Connector housing for microcircuit cards
The present invention relates to the field of readers for microcircuit cards, smart cards or smart cards. The present invention more particularly proposes a connector housing of a reader / writer device connected to a circuit for exploiting the data contained in a microcircuit card.
These devices are mainly used in the field of the banking transaction such as: - POS (point of sale) which are electronic payment terminals used by merchants for the payment by credit card of the expenses of their customers, - the cash registers department stores and supermarkets, - service stations, - devices for badges for the automatic payment of highway and urban tolls by all motorized vehicles.
Other areas of application of these devices are the Vitale card, the telephone card of public booths, parking ticket machines, tachographs for road hauliers, etc.
All these devices are characterized by the fact that the owner of the chip card of the format of a credit card manually introduces this card through a slot of a device housing by pushing it until it comes to bear on a card stop arranged at the bottom of the slot.
In the operating position, the rear part of the card remains visible and is generally used to grip the card to extract manually when the operations are completed.
In most applications, the device remains under the supervision of the one who exploits it: in its absence, this device is not accessible by third parties. However, in applications such as automatic service stations, the device is open to the public without supervision: additional precautions must be taken in the device to protect it from possible fraud.
The patents FR 2 722 592 and US 5 703 346 teach a monobloc connector housing to which a monobloc connector is attached. This housing has two parallel slides to guide two side edges of a microcircuit card. These slides are interconnected by a transverse connecting element having housings for receiving contact elements capable of cooperating with the card. This housing further comprises a second transverse element parallel and substantially identical in shape to the first transverse element to define a slot for the passage of the card and ensure the support of the card on the contact elements. Although substantially identical in shape, the two transverse elements have very different shape details specific to their functions. For example, a first transverse element comprises openings for the passage of contact blades of electrical connections while the zone opposite the second transverse element is full to allow its gripping by suction during the automatic installation of the housing on a printed electronic circuit. Similarly, the first transverse element has windows on either side of the contact zone with a microcircuit card to allow the implantation of other electronic components under the housing while the areas opposite the second transverse element are solid to ensure sufficient rigidity for its support function of the microcircuit card on the contact blades. The transverse elements and the slides of complex shape are made in one piece, this leads to manufacture a product of complex shapes. However, the injection of a molded plastic part of such a housing is difficult and has many disadvantages.
During the plastic injection of the housing, the differences in speeds and paths of the molten plastic material, in the two transverse elements having large disparities of shape details, generate a differential of withdrawals within the molded part which translated by deformations after the cooling following the injection as well as by a high level of stress that can be released during the reflow (temperature of the order of 250 ° C) for the implementation of the connector housing on the circuit printed electronics. To limit these deformations and constraints to an acceptable level, it is necessary to facilitate the flow of the molten plastic material in the first transverse element which is braked by windows located on either side of the contact zone and the plurality of opening openings of the latter for the passage of the contact blades. The method chosen is to add transverse sections (not initially provided as can be seen in US 5,703,346) in the middle of the windows. On the other hand, the solution of the casing molded in one piece does not make it possible to avoid the disturbances of the path caused by the opening openings of the contact passages. This results in a level of deformation on the molded part that must be managed, possibly with the aid of corrective actions, during assembly of the connector. The setting parameters of the injection molding machine are also difficult to regulate and a compromise has to be found between the risk of lack of filling in the first transverse element which has complex shape details difficult to fill if the injection pressure is insufficient. and the risk of burrs in the second cross member which has simple shapes, easy to fill, if the pressure is too high. This compromise of adjustment of injection parameters, which is very sharp, tends to change depending on the batches of plastic pellets and environmental conditions (temperature, humidity ...) during injection. This results in scrap and / or expensive sorting. The shape of the case presents another difficulty of molding: the slot of passage of the chip card located between the two transverse elements is thin (about 2 mm) and is obtained by molding with a sliding drawer in the mold. The dimensions, width and length, of this drawer are substantially those of the connector housing, so important, while its small thickness does not allow to arrange inside it a circulation of heat transfer fluid to cool at the same time. injection, unlike other molding parts of the mold. This problem is all the more crucial as the drawer is heated on both sides during the filling of the transverse elements. This results in: - a temperature differential between the inner and outer faces of the two transverse elements during the solidification of the molded part which participates in the nip of the slot in the middle. This pinching causes the friction of the two transverse elements on both sides of the microcircuit card during its introduction or extraction, hence the deterioration of the card, - premature wear of the drawer relative to the other mold parts during the molding of large series, resulting in a high maintenance cost.
Finally, the complexity of injecting the connector-box shape in practice limits the number of molding cavities in the same two or three-piece mold. Beyond that, the compromise on the injection regulation parameters becomes too sharp and the risks of rejection too high.
This type of housing in one piece, in addition to manufacturing disadvantages, has other disadvantages.
Usually, to ensure the protection of the card vis-à-vis the electromagnetic disturbances and / or hacking action performed on the device in order to read the data stored in the microcircuit of the card or exchanged by it, the housing the device must be shielded. As this type of housing does not allow shielding, it must be equipped with a flexible metallized envelope that encompasses the outer surface of the housing. This type of envelope is difficult to industrialize and is particularly expensive.
In addition, the windows located on either side of the contact zone are small because of the addition, resulting from a technical compromise, of the transverse sections which considerably reduce the space left available for the implantation of electronic components under the connector and reduce the size of the electronic components that can be implanted.
In addition, the centering and / or clipping pins coming from the molding with the housing are fragile and offer a low mechanical resistance to insertion thrust when the microcircuit card abuts the bottom of the connector housing. The addition of metal pegs machined by bar turning and glued into cavities of the housing is an expensive solution. The low height of these pins and their cylindrical shape do not allow to achieve a sufficiently elastic profile for a clipping function by pressure on the walls of the holes in which they are embedded in the PCB of the printed circuit.
Finally, the intrinsic deformations to the casing of the casing, despite the shape arrangements such as the addition of the transverse sections, make it difficult to obtain an overall coplanarity of plus or minus 0.05 mm on all the outputs of the blades. of contacts and the limit switch, which tend to reproduce the deformation of the housing on which they are mounted, without retouching performed manually on these blades during the final control of the connector housing.

The invention will be described with reference to FIGS. 1, 2, 2A, 3, 4, 4A, 4B, 4C, 4D, 5, 6, 7 and 8.
The present invention provides a housing (1) card connector (100) microcircuit, for example a credit card type credit card type ID-1 of ISO / IEC 7810). This housing (1) is intended to be mounted on a printed circuit board (PCB) (200). For example, the card (100) may be of rectangular shape with its four rounded corners and is delimited by an upper face and a lower face which comprises in the vicinity of its edge conductive pads made in the form of four pairs of two aligned ranges longitudinally in the insertion direction of the microcircuit card (100) in the housing (1) connector.
The first part of the description, which follows, will present the first embodiment of the housing (1) according to the invention shown in Figures 1,2, 2A, 3, 4, 4A, 4B, 4C, 4D, 5, 6 , 7 and 8.
The housing (1) connector comprises at least one frame assembly (10) contact holder and cover (50). This frame (10) one-piece contact carrier is inserted into the cover (50).
A microcircuit card (100) can then be inserted between the contact holder frame (10) and the cover (50).
The frame (10) contact carrier comprises at least on the same plane a first zone (32) lateral and a second zone (30) lateral on either side of a zone (31) central. The first zone (32) lateral and the second zone (30) lateral each form a ring whose center (33, 34) is recessed to allow the establishment, vis-à-vis each recess (33, 34) ring, electronic components supported by the PCB (200). These annular recesses (33, 34) are maximized to accommodate a large number of components that may be large under the connector housing (1).
In a preferred configuration, the rings (33, 34) have the shape of rectangles.
The first (32) lateral zone and the second (30) lateral zone are each formed of a longitudinal arm (27, 28), one parallel to the other.
The central zone (31) forms, with the annular lateral zones (30, 32), an H connected to the lateral zones (30, 32) by legs (25, 26) of the H parallel to longitudinal arms (27, 28). lateral zones (30, 32). The bar (24) of the H connecting the two legs (25, 26) of the H forms the contact support. At least one transverse arm (20, 21, 22, 23) connects a leg (25, 26) of the H with a longitudinal arm (27, 28) of a lateral zone (30, 32) at right angles to form each zone lateral.
The bar (24) connecting the two legs (25, 26) of the H constitutes a contact support which comprises a plurality of housings (44) each of which is arranged to receive by sliding in a slot parallel to the plane of the frame (10) at less a blade (5) resilient electrical contact for cooperating with the microcircuit of the card (100) microcircuit. The plurality of slides forming these housings (44) is arranged to receive at least one elongated contact blade (5) bent whose elbow (500) is positioned projecting in an opening formed between two slides. The bend (500) is intended to cooperate with the contacts of the microcircuit of the microcircuit card (100). The slides are arranged parallel to the first face of the frame (10) and another end (46) folded of the blade (5) contact being welded to contact pads of the PCB (200). The dimension of the contact support can depend on the number of housings (44) of blades (5) of contact that it comprises and the length of these blades (5) for which the housing (44) were designed. The number of elastic contact blades (5) is less than the number of housings (44). The position of the blades (5) is determined according to the type of microcircuit card (100) for which the housing (1) connector is manufactured. Each of these housings (44) is open at the top to allow each of the blades (5) of contact, extending through this passage opening, to bear elastically on the corresponding range of the card (100) with microcircuit inserted in operating position in the housing (1) connector. The electrical contact blades (5) extend in the opposite direction by a tab ensuring the electrical connection of each contact with a printed circuit range when mounting on the surface of the connector housing on the printed circuit. The bottom bottom of these housings (44) is in its greater part closed thus forming transversely continuity of material to allow a smooth flow during the injection of the molded part. In the case of a molded receiver case in one piece of the prior art, these housings are necessarily opening downwards to allow demolding of the part, thus creating strong discontinuities in shape which, during injection, significantly disturb the flow of the plastic in this area and greatly increase the flow velocity differential between the lower cross member and the upper cross member.
The at least one transverse arm (20, 21, 22, 23) connects a leg (25, 26) of the H with a lateral zone (30, 32) at right angles. The transverse arms (20, 21, 22, 23) connect at right angles each end of each longitudinal arm (27, 28) of the lateral zones (30, 32) at each end of the legs (25, 26) of the H. (20, 21, 22, 23) connects the end of a longitudinal arm (27, 28) of a lateral zone (30, 32) to the end closest to the leg (25, 26) of the H closest to the area (30, 32) side considered.
According to a preferred embodiment, the transverse arm or arms (22, 23) which connect the first zone (32) lateral to the central zone (31) have a length substantially equal to two-thirds of that of the arms (27, 28). longitudinals of the lateral zones (30, 32). The transverse arm or arms (20, 21) which connect the second zone (30) lateral to the central zone (31) have a length substantially equal to one third of that of the transverse arms (22, 23) which connect the first zone (32). ) to the central zone (31). The surface of the windows (33, 34) bounded by the lateral areas corresponding to the annular recesses, the legs (25, 26) of the H of the central zone (31) and the transverse arms (20, 21, 22, 23) cover a 65% of the total area of the two zones (30,32) lateral while the surface of the open windows (35,36) limited by the legs (25,26) of the H and the bar (24) of the H represents approximately 36% of the total area of the area (31)
H
Central.
The three-zone structure gives the contact frame (10) particularly advantageous molding properties. The injection being performed on the longitudinal arm (27, 28) of a lateral zone (30, 32), the molten plastic material flows simultaneously towards the front and towards the rear of the arm (27, 28). longitudinal, then in the two arms (20, 21, 22, 23) transverse. The material then flows from both ends of a leg (25, 26) from the H of the central zone (31) to the bar (24) of the H. The position of the injection point on the arm (27, 28) of the lateral zone (30, 32) is chosen so that the two streams of material arrive at the same time on the first end of the bar (24) of the H. These two flows which are joined at the first end of the bar (24) of the H combine into a smooth flow sheet along the latter to its second end. Then the combined flow then separates into two flows flowing in the front and bitter portions of the second leg (25, 26) of the H from the central zone (31) to the ends of the arms (20, 21, 22). , 23) transverse of the second zone (30) laterally, and along these two arms (20, 21, 22, 23) to the two ends of the arm (27, 28) longitudinal to finally meet in the latter. This structure thus allows a regular filling during the injection, avoiding any anarchic flow that would generate significant deformations, the molded part: with this structure the flatness obtained on the frame (10) contact door has a value that is less than half the maximum value allowed for the housing (1) connector.
The cover (50) is metallic and comprises at least one rectangular plate (72) which is predominantly flat and very slightly greater, in a non-limiting manner of the order of 2/10 mm, at one dimension of the microcircuit card (100). The cover (50) further comprises first means (501) for inserting and holding the frame (10) contact holder in the cover (50) by determining between the cover (50) and the frame sufficient sliding space for insertion of the microcircuit card (100) inserted between the frame (10) and the flat plate (72) of the cover (50).
The rectangular plate (72) has longitudinal and transverse dimensions which are substantially equal to those of the frame (10) contact-holder and very slightly, in a non-limiting manner of the order of 2/10 mm, greater than one dimension of the microcircuit card (100). The plate (72) comprises longitudinal members (51, 52) having a sliding surface (54) parallel to the plane of the plate (72). These rails (51, 52) are perpendicular to the plane of the plate (72) and parallel to the insertion direction of the card (100) in the housing (1), along two opposite edges of the plate (72).
The first insertion means (501) are arranged along longitudinal members (51, 52) parallel to the insertion direction of the microcircuit card (100) in the housing (1) along two opposite edges of the plate ( 72) of the cover (50) and are intended for insertion of the contact holder frame (10), the lateral zones (30, 32) of which are arranged to fit into the first cover insertion means (501) ( 50). The sliding space between the cover (50) and the frame (10) contact carrier are second insertion means (502) arranged along each spar (51, 52) and are intended for the insertion of the card (100) microcircuit for its implementation in a correct position on the frame (10) contact holder.
Sliding insertion of the frame (10) contact holder in the cover (50) is parallel to the plate (72) or insertion plane of the microcircuit card.
In order to form the first insertion means (501), two opposite lateral edges of the plate (72) are folded at right angles twice along two distinct lines parallel to the edges to form a spar (51, 52) for each of these edges. In the portion of the spar (51, 52) perpendicular to the plate (72), wings (53) are cut and folded on the same line parallel to the plate (72) towards the center of the hood (50) and to be parallel to the plate (72) of the cover (50).
The contact carrier frame (10) and the cover (50) define a passage slot for the passage of the microcircuit card (100) in the housing (1). A first face of the frame (10) contact-holder facing the plate (72) of the cover (50) is predominantly flat. It forms the sliding plane of the microcircuit card (100) on the contact holder frame (10) during insertion of the microcircuit card (100) into the casing (1). On this face, part of the face of the transverse arms contained in the first face of the frame (10) contact holder may be recessed relative to the sliding plane of the card (100) microcircuit to allow the passage of any engravings of it.
Part of the face of the zones (30, 32) contained in the first face of the frame (10) of the contact carrier may be recessed relative to the sliding plane of the microcircuit card (100) from a height to less equal to the thickness of the wings of the cover (50) to not interfere with the passage of the card (100) microcircuit. Vertical stop faces of the lateral zones form complementary abutment means which make it possible to abut against the wings (53) of the cover (50) due to the withdrawal relative to the sliding plane of the microcircuit card (100).
The second face of the contact carrier frame (10) has a housing (49) for receiving an optional shielding plate (90, 95). This housing (49) has a depth equal to or slightly less than the thickness of the shielding plate (90, 95), in a non-limiting manner of the order of 5/100 mm to 1/10 mm.
In order to detect the presence of a microcircuit card (100) in the casing when it is inserted into the operating position, the frame (10) may include a switch (6) provided with a triggering member. intended to cooperate with an edge of the microcircuit card (100). The switch (6) is integrated in a housing (261) opening at least on the first face of the frame (10) contact holder and located at one end of one of the legs (25, 26) of the H of the zone (31). ) central opposed to the introduction input of the microcircuit card (100) when inserted into the housing (1).
The flat plate (72) of the cover (50) may have protuberances (68) forming, in the same plane, bearing zones reducing the insertion space of the microcircuit card (100) between the zones of support and the blades (5) resilient contact carried by the frame (10) contact holder. These protuberances (68) make it possible to leave a sufficient spacing, between the internal face of the plate (72) of the cover (50) and the microcircuit card (100), for the passage of any embossed engravings provided, for example, by the ISO 7811-1, ISO 7811-3, ISO 7811-4 and ISO 7811-5 standards for smart cards and to prevent contact of the magnetic strip of the microcircuit card (100) on the cover plate (50).
These protuberances (68) can be obtained by stamping and / or stamping the plate (72) of the cover (50). They protrude into the slot and serve as pads on which a face of the card (100) slides during its insertion into the housing (1). They are arranged to leave the passage, without physical contact with the cover (50), embossed etchings and the magnetic strip possibly disposed on this face of the card (100). In the operating position, the card (100) is pressed against the protuberances (68) under the action of the blades (5) of contact and the actuator of the switch (6).
The cover (50) may comprise braking means (69) braking the microcircuit card (100) when it is inserted into the casing (1) and pinching the microcircuit card (100) for the duration of its use in the casing (1).
According to the first embodiment, the braking means (69) come to cut and fold the plate (72) of the cover (50). They provide, in the operating position, a holding force additional to that naturally exerted by the blades (5) of contact and the actuator of the switch (5). In some applications, these braking means (69) can be omitted.
The cover (50) has at least one stop means (58) perpendicular to the cover plate (50) defining, at one and the same time, an insertion end position of the contact carrier frame (10) inserted into the first means (501) and on the other hand, an insertion end position of the microcircuit card (100) inserted in the second insertion means (502).
These abutment means (58) are the result of folding an edge of the plate (72) perpendicular to the longitudinal members (51, 52) along a line parallel to this edge to form stop means (58). A part of the abutment means is cut to form an indentation and another part (60) is folded in a distinct line and parallel to the first fold to form a part (60) parallel to the cover plate (50), this part ( 60) being pressed to form at least one projection (57) intended to cooperate with a recess (18) located on at least one of the transverse arms (20, 21, 22, 23) for clipping and securing the frame (10). ) contact holder with the cover (50). This transverse arm (21, 22) is an opposite arm to the insertion input of the microcircuit card (100) when it is inserted into the casing (1). The portion (60) of the stop means (58) cut to form an indentation whose edge rests on an area (39) projecting from the end of the longitudinal arm (26) where the housing (261) is located, allows the central area of the hood (50) not to collapse if pressure is exerted on the hood (50).
When the microcircuit card (100) is inserted, the support of the portions (60) parallel to the cover plate (50) means (58) of abutment on the arms (21, 22) transverse of the frame (10) carries -contact prevents the central zone (31) of the hood (50) from being lifted by the action of the deflection forces of the contact blades (5) placed in the housings (44) of the contact support and which extend through the upper openings of these housings (44) to cooperate with the contact pads arranged on the face of the microcircuit card (100), and under the action of the deflection force of the switch (6).
The. frame (10) contact carrier may also include lifting feet (43) on the second face of the frame (10) contact holder which is not vis-à-vis the cover (50). These lifting feet (43) fix the height of the housing (1) connector relative to a printed circuit board PCB (200) when this housing (1) is placed on this printed circuit board (200).
The cover (50) has tabs (61) for fixing the housing (1) to a printed electronic circuit (200).
These fixing lugs (61) are made by cutting and folding part of the portion of the longitudinal members (51, 52) parallel to the plate (72) of the cover (50). They are formed of two elastic branches (62) which are delimited by a slot (64) which is extended by a portion (65) of the slot perpendicular to these tabs (61) on the part of the longitudinal members (51, 52) parallel to the cover plate (50), in the vicinity of the foot of these tabs (61). They allow, by sinking slightly into force in the corresponding holes of a printed circuit board (200), to accurately position the housing (1) connector. These lugs (61) for fixing ensure the maintenance of the housing (1) connector during soldering operations. This lug design (61) is particularly advantageous because the portion of the slot (65) perpendicular to the lugs (61) provides a very high elasticity to the two legs (62) of the lug (61) despite the low height of these branches (62) which is limited, in a nonlimiting manner, to approximately 2.8 mm so that their ends do not project from the side of the underside of the printed circuit board (200) of which [thickness is generally about 1.6 mm for example. Indeed, during insertion of the tabs (61) in the holes of the printed circuit board (200), the elastic deformation of the two branches (62), which approach each other, at their point of contact in the holes , generates on each of these a bending moment of vector perpendicular to their vertical plane which opposes a vector torsion moment parallel to the horizontal plane of their foot of the same value but of opposite direction. The thickness to be taken into account for the elastic deformation of the legs feet (61) is therefore the thickness of the metal sheet in which is cut the cover (50) which is 0.2 mm for example, while the thickness to take into account for the deformation of the branches (62) is their longitudinal dimension of cutting, about 1.5 mm for example. It is thus easily understood that the greater part of the elastic deformation of the tabs (61) is ensured by the twisting of their foot, even with a short length of the portion of the slot (65) perpendicular, or about 0.5 mm for example. These metal tabs (61) provide a high mechanical strength to the insertion forces of the microcircuit card (100) and allow the electrical connection of the cover (50) and the optional shielding plate (92, 95) to the electrical mass of the printed circuit board (100) by pressing the metallized wall of the holes of the printed circuit board (200) without the need for soldering in these holes. The cover (50) is shown in the figures with only two brackets (61) arranged staggered. A variant with four brackets (61) arranged symmetrically may be considered.
The housing (1) connector also has outputs (46) for electrical connection of the contact blades (5) and the electrical connection outputs of the switch (6) which are intended to be brazed by carrying flat on the board (200). printed circuit board on which it is mounted, or possibly by stitching when the outputs are of the type to stitch.
The edges of the contact holder frame (10) and the cover (50) at the input of the connector housing (1) can be chamfered to facilitate insertion of the microcircuit card (100) into the connector housing (1). .
For the first embodiment of the housing (1) connector, it is possible to add an optional shielding plate (90, 95). It may be for example the same metal as the cover (50) of the first embodiment and / or the same thickness.
It has an outer contour that matches that of the housing (49) located on the second frame face (10) contact holder.
The shield plate (90, 95) is placed in the housing of the contact carrier frame (10). This subassembly is then introduced into the first means (501) of insertion of the cover (50) to the interlocking and latching thereon.
The bottom of the housing (49) is recessed with respect to the second face of the frame (10) contact carrier of a height equal to or slightly less than the thickness of the plate (90, 95) shielding so that that the face of the shield plate (90, 95) placed in the housing is slightly protruding from the first face of the contact carrier frame (10). Thus, after nesting and snapping into the hood (50), the wings (54) of the longitudinal members (51, 52) parallel to the plate (72) of the hood (50) and the wings (60) of the parts ( 60) parallel to the plate (72) of the cover (50) means (58) abutment are in mechanical pressure on the plate (72) shielding, making electrical contact with these elements of the cover (50) holding it in position .
In a first embodiment of the shielding plate (90), the shielding plate (90) comprises openings (92, 93) of identical shapes to the windows (33, 34) delimited between each zone (30, 32) and the central region (31) of the contact frame (10), the openings (92, 93) of the shielding plate (90) facing the windows (33, 34) of the contact frame (10). This offers the same possibility of implantation of other components under the housing (1) connector that the housing version (1) connector without the plate (90) shielding. The central section of the shielding plate (90) between the two openings covers the entire area of the contact support to ensure good protection of the microcircuit of the microcircuit card (100) in operating position in the housing (1) connector .
In a second embodiment of the shielding plate (95), the shielding plate (95) is similar to the shielding plate (90) of the first embodiment with the exception of the openings (92, 93). The shielding plate (90) comprises instead embossings (96, 97) of shape corresponding to the openings (33, 34) formed by the windows delimited between each zone (30, 32) lateral and the zone (31) central frame (10) contact carrier and filling them. The volume available for the implantation of other components under the housing (1) connector is that of the size of the windows minus the material thickness of the embossings (96, 97). These embossings (96, 97) constitute a protective barrier between the microcircuit of the microcircuit card (100) and the components implanted on the printed circuit board (200) under the embossments.
The optional shielding plates (90, 95) do not change the size of the connector housing (1).
Other variants of optional shielding plates can, depending on demand, provide additional protections such as connection outlets, open windows, etc.
In the following description, a second embodiment of; housing (1) is shown in FIGS. 9, 10, 11, 11A, 12, 12A, 12B, 12C, 12D and 13.
This housing (1) connector is not shielded and is intended for devices for reading and / or writing card (100) microcircuit standard format of a bank card for which electromagnetic protection i at the connector n ' is not requested, thus benefiting from a lower cost and a lower mass in the first embodiment.
The hood (50) is molded of plastics material. Without limitation, the cover has a thickness of 7/10 mm. Apart from the shielding, this plastic cover (50) takes up all the functions of the metallic cover (50). It is designed to fit and snap together with the corresponding contact holder frame (10) in the same way as the connector housing (1) of the first embodiment. It is thus possible to use industrial means of assembly and control common to these two embodiments. Naturally, some forms specific to the stamping technique have been adapted to that of the molding.
The wings (54) in the part of the longitudinal members (51, 52) perpendicular to the cover plate forming the first means (501) for inserting the plastic cover (50) are molded, of discontinuous shape, for example, in three elements distributed along each of the two longitudinal members (51, 52).
The portions (60) parallel to the cover plate (50) of the stop means (58) are also discontinuous in three elements distributed over the portion perpendicular to the plate of the stop means (58).
The wings (53) of the first embodiment are replaced by bearing surfaces (153, 201) respectively disposed at the front of the longitudinal members (51, 52) and in notches arranged at the ends of the stop means (58). .
The protuberances (168) take the form of sliding and bearing rails projecting inwardly of the slot.
The protrusion (57) of the parts (60) parallel to the cover plate (50) of the stop means (58) for cooperating with a recess (18) on at least one of the transverse arms of the frame (10) takes the form of two elastic clips (157) molded in the extension of these portions (60) parallel to the cover plate (50).
The fastening tabs (61) coming from cutouts of the metal cover (50) of the first embodiment are replaced by brackets (61) of metal fasteners mounted and snapped into housings (213) molded with the feet (43). lifting, for example four in number, the frame (10) contact carrier.
The contact frame (10) of the housing (1) connector of the second embodiment is identical to the frame (10) of the housing (1) connector of the first embodiment with the exception of two pairs of studs (210, 211 ) molded with the frame (10) contact carrier. Each stud (211) of a first pair of studs extends one end of each zone (30, 32) side, the ends being those opposite to the introduction input of the card (100) microcircuit when inserted into the housing (1). Each stud (210) of the second stud pair is disposed along each lateral zone (30, 32) in the vicinity of the ends of the lateral zones (30, 32) closest to the input insertion of the card ( 100) with a microcircuit when inserted into the housing (1). In addition, the lifting feet (43) are located on the second face of the frame (10) contact holder at the housings (51, 52) in the same positions as those of the tabs (61) for fixing the housing (1). shielded connector. The lifting feet (43) comprise a housing (213) capable of receiving metal fastening tabs (61).
The contact carrier frame (10) receives the same contact resilient blades (5) and the same switch (6) as the frame for the connector housing (1) of the first embodiment.
As for the housing (1) connector, the frame (10) contact holder is engaged in a direction D1 in the first means (501) of insertion of the cap (50) of plastic. The faces of the frame (10) slide on the wings (54). At the end of nesting, the studs (210) of the second pair cooperate with the bearing surfaces (153) disposed respectively at the front of the longitudinal members. The pads (211) of the first pair engage in the notches arranged at the ends of the stop means (58) to cooperate with their bearing surface (201). When the contact frame (10) reaches the abutment means (58), the frame (10) and the cover (50) snap together and solidify to form the unshielded connector housing (10). According to a configuration, the action of plastic clips (157) which snap elastically into the recesses (18) of the contact frame (10) can be reinforced by those of four harpoons (214) coming from molding laterally to the frame (10) contact holder. These harpoons snap into recesses (177) made in the side rails of the hood (50). These four harpoons can also be made for the first embodiment on the frame (10) contact holder to reinforce the snap of the frame (10) by engaging in'des openings made in the perpendicular part of the side rails hood metal (50).
In one configuration, two wings (78) perpendicular to the plate (72) of the cover (50) coming from molding the ends of the longitudinal members (51, 52) close to the insertion input of the microcircuit card (100). 'fit into corresponding slots (225) made in the studs (210) of the second pair to reinforce the mechanical strength of the part of the longitudinal members (51, 52) close to the card insertion input (100) to microcircuit under the action of any lateral forces that could be exerted by the microcircuit card (100) during its insertion.
In the event of pressure exerted on the top of the plastic cover (50), pressing the edge of the stop means (58) against the protruding part (539) of the housing of the switch (6) coming from molding the frame (10) contact carrier prevents the central area of the hood (50) from collapsing.
The fastening tabs (61) have a planar shape having an axis of symmetry. They comprise two branches (62) of similar shape and dimensions to those of the fixing tabs (61) of the first embodiment. The two legs (62) are separated by a slot (63). The upper lateral end of each of the branches (62) comprises a stop (76) and is extended by a spur (79) provided with two harpoons (77). The upper central ends of the two branches (62) are interconnected by a central branch (81) which extends upwardly parallel and between the two spurs (79). The upper end of the central branch (81) has a rectangular window (82) whose upper edge serves as a non-return stop face.
The housing (213) formed in each foot (43) for lifting the frame (10) contact holder is capable of receiving a lug (61) attachment. The frame (10) contact carrier is represented by the figures with only two ~ lugs (61) arranged staggered. This representation is not limiting. For example, a variant with four brackets (61) arranged symmetrically can be considered.
The housing (213) has the shape of a slot which is open at its lower part and ends in its upper part by faces (223) stop. The thickness of the slot (213) is substantially equal to that of the tab (61) of attachment. The upper end of the slot (213) has a detent (219) provided with a ramp (224) and a face (218) stop. The slot (213) is vertically stepped: the edges (221, 222) side of the slot (213) define between them faces (216) stop. A second clearance slot (217) whose thickness is substantially twice the width of the slot (213) and the width is substantially equal to half that of the slot (213) extends parallel and symmetrically to the slot (213) facing the notch (219) stop. The second slot (217) is open at both ends.
The bracket (61) is inserted into its housing (213) in a direction D2 perpendicular to the frame (10) contact holder. The spurs (79) engage in force in the slot (213) and the harpoons (77) cooperate with the edges (222) of the side slot (213) to achieve a recess eliminating any risk of mechanical play of the paw in his dwelling (213). During the insertion, the lateral edges (84) of the limbs (62) slide on the lateral edges (221) of the slot (213) and provide guidance and lateral support of the fastening tab (61) in its housing (213). At the end of insertion, the upper edge of the central branch (81) cooperates with the ramp (224) of the catch (219) by elastically deforming the central branch (81) which flexes in the second slot (217). clearance slightly wider than the central branch (81). The fixing lug (61) has abutments (76, 85) which bear on the respective stop faces (216, 223) of the housing (213), the central branch (81) snaps onto the notch ( 219) by engaging the upper edge of the window (82) on the stop face (218) of the detent (219), thereby securing the fastening tab (61) in its housing (213). This design of the lug (61) inserted in the metal foot (43) of the lifting frame (1G) contact holder has a particularly high mechanical strength and substantially equal to that of the tab (61) for fixing the hood (50) metal of the first embodiment.
The frames (10) contact carrier shown in the figures comprise eight pairs of housings (44) capable of receiving blades (5) contact. Only the four pairs of housings (44) located near the center of the frame (10) contact carrier are equipped with blades (5) of contact: they correspond to the positioning currently applied for the ranges defined by the standard standard of the card (100). ) with microcircuit.
