    The invention relates to an arrangement comprising an electrical device, which has a device housing and at least one socket, and a connecting cable, via which the electrical device can be connected to a further electrical device and which is connected to the device by a cable connector attached to the connecting cable , A soft connector housing and having a projecting out of the connector housing plug-in extension with which the cable plug is inserted into the socket of the electrical device, wherein electrical contact elements of the plug-in extension contact electrical mating contact elements of the socket.
    To selectively connect electrical devices, such as computing devices, to peripheral devices, such as storage devices, the devices to be connected may be conventionally provided with sockets in which cable plugs mounted on either side of an electrical cable are inserted. For this purpose, different standardized types of connectors are known, in the computer field u.a. USB connectors.
    In many types of connectors, such as USB connectors, it is possible to pull the cable connector by a pull on the cable connector or on the cable from the socket, without the need for previously a lock must be solved. This has the advantage of easy closing and opening of the connector, however, it may also result in unintentional opening of the connector, for example, by an unwanted tensile load on the cable. If the devices to be connected are mobile devices, the connection of the devices via a separate cable also has the disadvantage that the entrainment of such a cable can be forgotten or a cable entrained can be lost.
    For example, therefore, manufacturers of external storage devices, which are intended in particular for use in connection with mobile computing devices, partly switched to install a fixed cable in the storage device, which has at its free end a cable connector for connection to a computer device. Such a built-in cable can thus not unintentionally solve the device in which it is installed, and can not be forgotten, but is disadvantageous in other respects. So there is always the risk of cable breakage, especially in the area in which the built-in fixed cable from the device emerges from this. In one of the highly integrated design but a user-side replacement of the cable is generally not possible. A repair by a specialist is time consuming and costly. It should also be borne in mind that storage devices in particular usually contain valuable and / or sensitive data for the user. Replacing the storage device with another would be associated with the loss of that data.
    To counter the problem of unintentionally loosening a USB plug from a USB socket, additional locking devices are known by means of which the USB plug is held in the USB socket. Such a device is apparent from US 7,559,788 B2.
    In addition to peripherals that are connected via a cable to a computer device, even very small-sized peripherals are known in which a connector, in particular USB connector, is integrated directly into the device. The device housing thus also represents a connector housing from which the plug-in extension of the plug, in particular USB plug, protrudes. Such wireless USB devices are widely used in the form of USB memory sticks or USB modems with SIM cards, for example.
    From JP 2011-164961 A, a wireless USB device with a locking device protrudes to prevent unauthorized removal of the USB device from the computer device.
    In order to reduce the overhanging length of a USB wireless device plugged into a computing device, it is known to provide a pusher extension pivotable relative to the housing of the USB device. Such training is evident, for example, from CN 201345479 Y.
    CN 2010-039596 A shows a USB socket with a swiveling socket, into which the plug-in extension of a wireless USB device is plugged. The pivoting socket with the inserted USB device can be pivoted so that the long side of the connector housing of the USB device comes to rest against the device housing in which the socket is mounted. The protruding length of the USB device is thereby reduced.
    US 2004/0208035 A1 discloses a storage device which has a permanently installed cable with a USB cable plug attached thereto. In one possible configuration, the cable is remote from the device housing and the plug-in extension of the USB cable connector can be plugged into a USB connector on the computer device to connect the storage device to a computer device. In another configuration, the USB connector can be folded with the cable so that the connector housing of the USB connector is connected to the device housing and forms a unit. To connect the device to a computer in this device configuration, the computer may have a bay in the area of which a USB socket is mounted. The storage device can be inserted in this case a total of the slot, the plug-in extension of the USB connector is plugged into the USB socket. The storage device is thus included as a whole in the shaft of the computer case.
    The object of the invention is to provide an advantageous connection between an electrical connection cable and an electrical device, in particular a device having microelectronic components, by means of which
    Disadvantages of the described conventional connections of connecting cables can be overcome with electrical equipment. According to the invention, this is achieved by an arrangement having the features of claim 1.
    To form the connection according to the invention between the electrical device and the connection cable, the device housing of the electrical device is formed with a shaft extending from an outer surface of the device housing. The device housing is thus formed with a cavity open to this outer surface of the device housing, which forms the shaft. When the cable plug fixed to the connecting cable is inserted with its plug extension into the socket of the electrical device, the plug housing of the cable plug is at least over a part of its measured parallel to the longitudinal axis of the shaft length, preferably at least over more than 50% of its measured parallel to the longitudinal axis of the shaft Length, more preferably over more than two thirds of its length within the shaft of the device housing.
    The protruding over the device housing length of the plug housing of the cable connector can thereby be at least reduced and a more compact design can be provided. The risk of unintentional loosening of the cable connector from the socket can already be reduced by the fact that the free attack surface on the connector housing is at least reduced. Advantageously, in addition, so little play between the plug housing and the shaft can be formed that, in the case of a pull on the connecting cable, which is at a small angle at an angle to the longitudinal axis of the shaft, tilting of the plug housing in the shaft or at least high friction occurs of the connector housing opposite the shaft comes. The risk of accidental withdrawal of the cable connector from the socket by an unintentional force acting on the cable tensile force can be significantly reduced. The probability that such an unintentional acting on the cable tensile force acts exactly parallel to the longitudinal axis of the shaft is very low.
    The plug housing can be held by friction in the shaft in a possible embodiment of the invention, even with respect to a tensile force acting parallel to the longitudinal axis of the shaft. In such a design, even with a centered orientation of the plug housing in the shaft at least over a part of the measured parallel to the longitudinal axis of the shaft length of the plug housing at least over a part or more parts of the circumference of the plug housing, a contact between the outer surface of the plug housing and the Shaft delimiting wall in front.
    A positive retention relative to a pulling force acting parallel to the longitudinal axis of the shaft is conceivable and possible. For this purpose, the connector housing outside at least have a survey, which is formed by an elastically deformable material of the plug housing and engages in the inserted state of the cable connector in a recess in the wall of the shaft. For example, the survey of the plug housing may be formed in the form of a circumferentially circumferential bead and the recess in the wall of the shaft in the form of a circumferential groove about the longitudinal axis of the shaft.
    Preferably, the coefficient of static friction between a material forming at least part of the outer surface of the plug housing and at least part of the material forming the wall of the duct is more than 0.7, more preferably more than 1. This is conveniently at least for portions of the outer surface of the Plug housing and the wall of the shaft, which are in the inserted state of the cable connector into the socket opposite each other, the case.
    In an advantageous embodiment it is provided that at least over a portion of the longitudinal extent of the shaft with respect to the entire circumference around the connector housing at most a gap between the connector housing and the wall of the shaft is present, whose size is less than 0.5mm, preferably less than 0, 3mm, more preferably less than 0.2mm. Conveniently, the length of the section of the duct over which the maximum size of the gap between the plug housing and the wall of the duct is limited in the manner as stated above is at least 3 mm, preferably at least 5 mm. With such a design it can be provided that at least at one point of the longitudinal extent of the shaft, a circumferential contact of the plug housing with the wall of the shaft is present, for example by the plug housing having an externally encircling bead-shaped elevation of an elastically deformable material. The wall of the shaft may conveniently have a circumferential groove-like depression in which engages the bead-shaped survey.
    The cable connector may have a kink protection sleeve for the connection cable in the usual way. This protects the connecting cable in the adjoining the cable connector area from damage due to buckling loads. In the context of this document, the kink protection grommet is regarded as part of the plug housing, regardless of whether the kink protection grommet is formed integrally with the plug housing or is formed by a separate part which is connected to a main part of the plug housing. In an advantageous embodiment of the invention, in which the cable connector is formed with such a kink protection grommet, only the kink protection grommet or a part of the kink protection grommet protrudes from the appliance casing in the plugged-in state of the cable plug, i. the connector housing is completely absorbed in the shaft, apart from the kink protection grommet or a part of the kink protection grommet. Preferably, in this case, a step in the connector housing is provided in the region of the transition between the main part of the plug housing and the kink protection sleeve and this step is flush with the outer surface of the device housing. It can be a visual impression of a permanently installed in the device connection cable awakened. The cable connector can be largely protected against unintentional release from the socket. In the event that the cable connector is formed without kink protection grommet, is advantageously a back of the connector housing flush with the outer surface of the device housing when the cable plug is inserted into the socket. Also in this case, the visual impression of a permanently installed in the device connection cable can be awakened and the cable plug to be largely protected against unintentional release from the socket.
    In the bottom of the shaft, an opening is advantageously provided whose cross-sectional area makes up only a part of the cross-sectional area of the entire shaft in the region of its bottom. In this case, the connector extension plugged into the socket protrudes through the opening in the bottom of the shaft into an interior of the device housing, in which at least part of the socket is located, and / or the socket, which lies partially in the interior of the device housing, protrudes through the opening in the ground of the shaft out of the interior of the device housing. It is thus a simple installation of the socket on a board in the interior of the device housing allows, as is known.
    By at least partially receiving the plug housing in the shaft of the device housing, a watertight or at least water-protected plug connection can be made possible or improved in a simple manner, ie. Ingress of water into the interior of the device housing is prevented or at least made more difficult, at least in the plugged into the socket state of the cable connector. For this purpose, it may be sufficient to make the maximum size of an optionally existing gap between the outer surface of the plug housing and the wall of the shaft sufficiently small. In addition or instead, a seal could be provided which lies between the plug housing and the device housing and is arranged inside the shaft on the device housing or is arranged on a part of the plug-in socket in the inserted state of the cable connector within the shaft lying portion of the plug housing.
    The electrical device of the arrangement according to the invention may be a storage device, for example in the form of an SSD. However, it can also be another peripheral device for a computer device or else a computer device to which a peripheral device can be connected. The invention can also be used with other electrical devices, in particular those with microelectronic components.

    The figures have different scales. In the figures, the sections through the cable connector and the socket are shown simplified and further contained in the interior of the device housing components only indicated schematically.
    The arrangement illustrated in FIGS. 1 to 25 comprises an electrical device 1 and an electrical connection cable 2 with a cable plug 3 attached thereto. In FIGS. 1, 5-7 and 11-14, the state of the connection cable connected to the electrical device 1 is shown shown, with the exception of Fig. 11 of the connection cable 2 only one of the cable connector 3 subsequent end portion is shown. At the other end of the connection cable, a further cable connector 32 is preferably attached to connect the electrical device 1 via the connection cable 2 with a further electrical device 34, as shown schematically in Fig. 11. The further cable connector 32 may e.g. A plug socket 33 in the interior of the further electrical device 34, in which the cable plug 32 is inserted, is indicated in Fig. 11 by dashed lines. In principle, the connection cable 2 at the other end could also be built into the further electrical device 34, i. the cable strands of the connection cable 2 (not shown in the figures) are directly and permanently connected to connection elements of the further electrical device 34, for example, soldered to this.
    The electrical device 1 may contain microelectronic components 35, which are indicated schematically only in FIG. 6 together with a circuit board 21. For example, the electrical device 1 may be a data processing device. In particular, it may be a peripheral device of a computing device, e.g. a mobile computing device, such as a data storage device. About the connection cable 2 can then be made the connection to the computer device. By such a data storage device, which is designed for example as an SSD, the storage capacity of the computing device can be extended.
    On the other hand, the electrical device 1 could, for example, also be a computer device and could be connected to a peripheral device via the connection cable 2.
    Electrical components of the device 1, which preferably comprise microelectronic components 36, are arranged within a device housing 4, that is to say in the interior 28 of the device housing 4.
    For connection to the cable connector 3 attached to the connection cable 2, the electrical device 1 has at least one socket 5. The cable connector 3 and the socket 5 may be, for example, a USB cable connector and a USB connector. In a preferred embodiment of the invention, the cable connector 3 is a USB plug according to the standard 3.1 type C and the socket 5 to a standard socket according to this standard. In the figures, such types of cable connectors 3 and sockets 5 are shown simplified.
    The cable connector 3 has a connector housing 6, in particular all or at least partially made of plastic, and a plug-in extension 7, which projects on the plug-in side of the connector housing 6. At the plug-in extension 7 electrical contact elements 8 are arranged. In the embodiment of the cable connector 3 shown in the figures, two rows of electrical contact elements 8 are provided, which are mounted on a respective contact carrier 10 and opposite each other and have a space between them, in which a mating contact carrier 17 of the socket 5 described below can be inserted.
    The electrical contact elements 8 are in electrical connection with the cable strands of the connection cable 2, not shown in the figures. For example, the cable strands are soldered to a circuit board 9, with which the contact carrier 10 are connected. The contact carrier 10 are surrounded by a metal sleeve 11. The circuit board 9 is surrounded by a plastic part 12 and an electrically conductive shielding film (not shown). These parts, which are within the connector housing 6, are shown in simplified form in the figures and correspond to the prior art.
    The connector housing 6 may in particular be a molded plastic housing, also according to the prior art. A remote from the Einsteckseite end portion of the plug housing 6, which is integrally formed with the rest of the plug housing (= main part 6b of the plug housing), in this case forms a kink protection grommet 6a. This kink protection sleeve 6a surrounds an end portion of the connection cable 2. Within the kink protection sleeve 6a is only the connection cable 2. Other parts of the cable connector are not in the region surrounded by the kink protection sleeve 6a.
    6, 7 and 25 through the cable connector 3 (ie, a parallel to the longitudinal axis 13 of the adjoining the cable connector 3 portion of the cable 2 section, which passes through the longitudinal axis 13), is a step 6c between the Bend protection grommet 6a and the main part 6b before. While the main part 6b of the plug housing 6 in the embodiment has a rather oval shape, the kink protection sleeve 6a is formed substantially with a circular outer contour.
    The longitudinal axis 13 of the cable 2 in the adjoining the cable connector 3 section is located with the longitudinal axis of the cable connector 3 on a common line.
    The socket 5 has a female housing 14, which is formed by a, here partially double-walled, metal sleeve. On the plug-in side, the socket housing 14 has an insertion opening for the plug-in extension 7. The socket has electrical mating contact elements 16 for contacting the electrical contact elements 8 of the cable connector 3. In the exemplary embodiment, the electrical mating contact elements 16 are arranged in two rows on both sides of a mating contact carrier 17. The illustrated socket 5 is formed according to the prior art and the representation is simplified. Conveniently, the female connector 5 may be directly connected to a circuit board 21 of the electrical device 1, in particular soldered to this. For electrical connection, the socket on electrical connecting elements 18, 19, which are inserted through openings in the board 21 (connecting elements 18) and / or superficially attached contacts of the board 21 are connected (connecting elements 19). In addition, mechanical connection elements 20 may be provided for connection to the circuit board 21.
    The device housing 4 has an outgoing from a surface 22 of the device housing 4 shaft 23. It is therefore an open towards the surface 22 channel or channel-like cavity, the longitudinal extent of which extends in a straight line in the direction of a longitudinal axis 24. The depth (= length) d of the shaft 23 measured parallel to the longitudinal axis 24 of the shaft 23 is preferably greater than any clear width w, w 'of the shaft measured at right angles to the longitudinal axis 24, cf. FIGS. 9 and 16.
    The longitudinal axis 24 of the shaft 23 is in the embodiment perpendicular to the surface 22 of the device housing 4, from which the shaft 23 emanates. A deviating angular arrangement, for example in the range of 90 ° +/- 45 ° but is conceivable and possible.
    In the context of this document, the surface (s) which delimit the shaft (23) in its entirety is referred to as the wall (25) of the shaft (23). In the embodiment shown, at least over a portion of the longitudinal extension of the shaft in cross section through the shaft, see. Figs. 13 and 17, there are two parallel walls joined by opposed arcuate wall sections adapted to the outer shape of the plug housing 6. In other embodiments, the shaft 23 could be bounded by a cylindrical wall, for example.
    In the bottom 26 of the shaft 23, which limits the shaft 23 in its longitudinal extent, an opening 27 is formed. The opening 27 is thus located between the shaft 23 and the interior 28 of the device housing 4. The socket 5, which is fixed in the interior 28 of the device housing 4, in the embodiment of the board 21, interspersed with its female housing 14, the opening 27 in the bottom 26th of the shaft 23.
    Between the bottom 26 and the female housing 14, an elastic sealing ring 29 is arranged in the exemplary embodiment, which seals the female connector 5 relative to the bottom 26. If the socket 5 is sealed against a passage of entering into the insertion opening 15 in the socket 5 water, thereby the interior 28 of the device housing 4 is sealed against ingress of water, even without a plugged into the socket 5 cable connector 3. The sealing ring 29 is arranged in a groove in the region of the bottom 26 passing through the opening 27, but could for example also be arranged on the outside of the female housing 14, for example, be vulcanized or molded.
    For connecting the connecting cable 2 to the electrical device 1, the cable connector 3 is plugged with its plug-in extension 7 in the insertion opening 15 of the socket 5. For this purpose, the cable connector 3 is inserted into the shaft 23. The insertion of the plug extension 7 of the cable connector 3 in the socket 5 is parallel to the longitudinal axis 24 of the shaft 23rd
    In the inserted state is in the illustrated embodiment, the entire body 6b of the plug housing 6 within the shaft 23 and closes on its back (= level 6c between the main part 6b and the anti-kink sleeve 6a) flush with the surface 22 of the device housing 4, from which the shaft 23 goes out. Only the anti-kink sleeve 6a of the cable connector 3 thus protrudes from the shaft 23 and projects from the device housing 4.
    In other embodiments, it would also be conceivable and possible that the main part 6b is not completely in the shaft 23, so a rear portion of the main part 6b still protrudes from the shaft, preferably less than a quarter of the parallel to the longitudinal axis 24 of the shaft 23 measured Length of the main part 6b protrudes from the shaft. On the other hand, the kink protection sleeve 6a or a part of the kink protection sleeve 6a could also lie within the shaft 23.
    In an embodiment of the cable connector 3 without kink protection sleeve 6a, it would be preferable for the rear end of the connector housing 6 to terminate flush with the surface 22 from which the shaft 23 originates. The plug housing 6 could also protrude beyond the rear section of the shaft 23, wherein the protruding portion would preferably be less than a quarter of the total measured parallel to the longitudinal axis 24 of the shaft 23 length of the plug housing 6, or the plug connector housing could with its back lie within the shaft, so that even when plugged in a recess in the shaft remains.
    The shaft 23 has a guide section 30, via which the width of the shaft measured at right angles to the longitudinal axis 24 is smaller, at least with respect to a part of the directions perpendicular to the longitudinal axis 24, than in other sections of the shaft 23. In the exemplary embodiment, the guide section 30 directly adjoins the outer surface 22 of the device housing 4, from which the shaft 23 emanates. The guide section could also be arranged deeper in the shaft 23. Conveniently, at least over the guide portion 30 is provided that, based on two directions that are perpendicular to each other and perpendicular to the longitudinal axis of the shaft, the outer diameter of the plug housing less than 0.5mm, preferably less than 0.3mm, more preferably less than 0.2mm , smaller than the diameter of the shaft. In the embodiment this applies to the entire length over which the cable plug is inserted into the shaft. Over the length of the guide section this applies in the exemplary embodiment in all directions at right angles to the longitudinal extent of the shaft.
    The plug housing 6 of the plug connector 7 inserted into the socket 5 cable connector 3 has in the guide portion 30 of the shaft relative to the shaft only a small amount of play. Advantageously, the play in the sense of a freedom of movement with respect to a parallel displacement perpendicular to the longitudinal axis 24 of the shaft 23, less than 0.5mm in all directions perpendicular to the longitudinal axis 24. A value of less than 0.3mm is preferred, more preferably a value of less than 0.2mm. The play in terms of a freedom of movement with respect to a tilting of the connector housing 6 about an arbitrary axis perpendicular to the longitudinal axis 24 of the shaft 23 is advantageously less than 2 °, with a value of less than 1 ° is preferred.
    In another section of the shaft 23 than the guide section 30, the play between the plug housing 6 and the wall of the shaft is greater at least in relation to a part of the directions perpendicular to the longitudinal axis 24 of the shaft 23 than in the guide section, cf. Fig. 14.
    The guide portion can be formed by raised portions 36 of the wall 25 of the shaft, cf. in particular Fig. 3, 4 and 10. In the embodiment are in cross-section perpendicular to the longitudinal axis 24 seen such raised portions 36 of the wall of the shaft 23 in the corner regions of the shaft 23, which is otherwise rectangular.
    In the region of the guide portion 30 so conveniently a clearance between the plug housing 6 and the shaft 23 is present. According to the fitting system "unitary bore", in particular clearance fits corresponding to H8 / h9, H7 / g6, H7 / h6 could be used, whereby the clearance fit H7 / g6 is preferred.
    The fact that such a clearance fit is made only on the guide portion 30 and in the other sections of the shaft on the other hand a larger game compared to the connector housing 6 is present, the manufacturing cost can be reduced. The risk of tilting of the connector housing 6 in the shaft 23 can be reduced.
    The length of the guide section 30 measured parallel to the longitudinal axis 24 of the shaft 23 is preferably less than half the length d of the shaft 23.
    In modified embodiments, the guide portion could also extend over the entire length of the shaft 23, over which the wall 25 of the shaft 23 in the inserted state of the cable connector 3 opposite the connector housing 6, or the shaft 23 could be formed without a special guide portion 30, i. the shaft 23 has the same cross-sectional dimensions over its entire length, to which the above statements apply to the guide section 30.
    Due to the small clearance between the connector housing 6 and the shaft 23, at least in the region of the guide section 30, there already occurs at a slightly oblique to the longitudinal axis 24 of the shaft 23 acting train on the connection cable 2 to tilt the connector housing 6 in the shaft 23, which a withdrawal of the plug housing 6 from the shaft 23 counteracts, or at least leads to a strong increase in the force required for pulling the cable connector 3 from the shaft 23 and the socket 5.
    This is favorably supported by a high static friction coefficient (= coefficient of static friction), which is present at least in sections between the outer surface 31 of the main part of the plug housing 6 and the wall 25 of the shaft 23. Preferably, the coefficient of static friction between the material forming the outer surface 31 of the plug housing 6 and the material of the wall 25 of the shaft 23, which has this in the guide section 30 is greater than 0.7, preferably greater than 1.
    For example, the plug housing 6 can be made of a polyvinyl ester (PVE) for this purpose. Other plastics come into question for this purpose. It could also be provided to coat the connector housing 6 with a corresponding plastic having a high coefficient of friction, for example PVE. Also, only over a part of the plug housing (based on its longitudinal extent and / or circumference) such a plastic could be provided with a high coefficient of friction.
    The wall of the shaft is advantageously formed at least over the guide portion 30 of a, for example by sandblasting, roughened metal surface. Such a roughened metal surface could also be provided only over part of the circumference of the shaft 23 and / or part of the longitudinal extension of the guide section 30.
    It is also conceivable and possible that the plug housing 6 of the cable plug 3 inserted into the socket 5 with its plug-in extension 7 is free of play relative to the shaft 23 at least in relation to a movement clearance in the sense of a parallel displacement perpendicular to the longitudinal axis 24. For this purpose, at least over a portion of the shaft 23, a contact of the plug housing 6 on the wall 25 of the shaft 23 is formed. This can be provided in particular over a part of the guide section 30. The connector housing 6 is then frictionally or frictionally and positively held in the shaft 23, even with a parallel to the longitudinal axis 24 acting on the connection cable 2 tensile force. The coefficient of static friction between the material forming the outer surface of the plug housing and the material of the wall 25 of the duct 23 can then be more than 0.7, preferably more than 0.7, over at least portions of the abutting areas of the outer surface of the plug housing 6 and the wall of the duct 23 1 amount.
    As a result of the construction according to the invention, in the inserted state of the cable connector 3, protection against ingress of water up to the contact elements 8 and mating contact elements 16 which are in contact with one another can be effected or improved. Such protection can be formed alone a small gap between the outer surface of the plug housing 6 and the wall 25 of the shaft 23. However, the outer surface of the plug housing 6 or via this projecting, arranged on the plug housing 6 sealing ring can also abut circumferentially on the wall 25 of the shaft 23. Instead or in addition to the wall 25 of the shaft 23 may be provided a sealing ring which projects beyond the wall 25 of the shaft 23 and circumferentially abuts the outer surface of the plug housing 4.
    As shown in the figures, the device housing 4 may comprise an upper housing part 4a and a lower housing part 4b, which can be connected to one another. Conveniently, in this case, as shown in Fig. 4, a part of the wall 25 of the shaft 23 from the lower housing part 4b and another part of the wall 25 of the shaft 23 are formed from the upper housing part 4a. In particular, that can
    Housing upper part 4a and the lower housing part 4b each have half-shell-shaped areas, which together form the shaft 23.
    The lower housing part 4b and the upper housing part 4a may also each have a portion of the bottom 26 of the shaft 23.
    4, in the sections of the lower housing part 4b and upper housing part 4a, which form the wall of the shaft 25 as a whole, raised areas 36 adjoining the outer opening of the shaft can also be seen in order to form the guide section 30 of the shaft 23.
    A modified embodiment of the invention will be explained below with reference to FIGS. 26 to 31. Apart from the differences described below, the previous embodiments related to the first embodiment are also applicable to this second embodiment.
    In this modified embodiment, the connector housing has a peripheral outer elevation (= bead) 6d. This can be formed as shown in one piece with the rest of the connector housing.
    In the wall 25 of the shaft 23 a around the longitudinal axis 2ides shaft 23 circumferential groove-like recess 37 is formed.
    If the cable connector 3 is inserted into the socket 5, the survey 6d of the plug housing 6 projects into the recess 37. The elevation 6d forming elastic material of the plug housing 6 can be compressed in this case. When the cable plug 3 is inserted and the portion 6d of the plug housing 6 having the elevation 6d is inserted into the shaft 23, the material forming the elevation 6d is first compressed more strongly and then, when entering the recess 37, it can at least partially relax.
    In this way, it comes in the inserted state of the cable connector 3 to a
    Positive connection between the cable connector 3 and the device housing 4, which counteracts pulling out of the cable connector 3 from the socket 5.
    Such a construction may also provide a seal against ingress of water.
    On the other hand, the survey could 6d, and possibly also the recess 37, extend over only part of the circumference or it could at one or more peripheral points a survey, such as knob-like survey, be provided which engages in a corresponding recess.
    By such a design can be achieved that no noticeable game with respect to a parallel displacement of the connector housing is perpendicular to the longitudinal axis 24 of the shaft 23. If elevations 6d and depressions 37 are provided at different locations with respect to the longitudinal extension of the shaft 23, it can furthermore be achieved that there is no appreciable play of the plug housing 6 with respect to tilting about any axis perpendicular to the longitudinal axis of the shaft 23.
    The invention is also applicable in connection with other types of cable plugs and sockets than those shown in the figures and described above. Thus, the invention is also advantageous for cable connectors and sockets for a different USB standard than the USB 3.1 type C can be used. However, the invention is also applicable to other cable connectors and sockets as such after a USB standard.
