    CONNECTOR FOR ISOLATION DISPLACEMENT Field of the invention
    The present invention is framed in the sector of the connectors by displacement of the insulator, more specifically in those constituted by a metal sheet cut or punched and folded and in which said displacement and connection are made by inserting the cable between two blades.
    Background of the invention
    Insulation displacement connectors, also known as IDC's (acronym for Insulation Displacement Connector), of the type comprising two cutting and connection blades each provided with a centering and insertion section of a cable and a cutting edge are known which extends to the centering and introduction section.
    These are the basic parts of these connectors. They are used as follows. In the first place, the cable is supported in the sections of centering and introduction of blades, which define a concave housing, at the bottom of which there is an opening defined by the separation between the initial sections of the blades. Then, directly manually or by means of a pressure lever belonging to a complementary part of the connection, such as a multiple connection housing, the cable, arranged with the longitudinal axis of its core perpendicular to the plane of the sheets, is pressed so that the sheets sequentially make a cut in the cable sheath and finally a contact, with eventually a plastic deformation of the metal core of the cable. As a result of the operation, an electrical contact has been established between the connector and the cable core.
    These connectors are completed with a support base, which will normally be that part intended to come into contact with another conductor for the conduction of the current, and connecting arms of each leaf to the base. In this base a guide is usually housed that brings the cable to its correct insertion position in front of the blades and a cable pressure lever.
    There are many examples of this type of connectors, among which the following can be highlighted, for presenting characteristics similar to those of the present invention:
    US6431903, US2012178315, JP2014212094, JP2014203568, W010029392, US2011117769, JP2003045510, US2013323988, US6142817, US5997336, US4773875, CN103825123.
    In these connectors and in the absence of stress and deformation due to the presence of a cable, the edges of the blades / blades are parallel. The arrangement of the leaves is usually faced, the leaves being joined at the bottom, so that these are practically rigid, at least in the face of rotations of the leaves in the plane that contains them. This condition and the fact that the diameter of the cable is greater than the separation between sheets means that the force is not constant and that the depth of the cable lock and the force exerted by the sheets are not controlled correctly, so that easy breakage occurs or the blocking force is insufficient and barely resists tensile forces on the cable.
    In DE202014106002, US2011076898 or US5685733, for example, it is proposed to guarantee a control of the force of the blades, so that they can pivot on points near the centering and introduction sections, specifically by means of a die cut of the leaves that make them “hang ”Of the lower ends of the mentioned sections of Centering and Introduction. The resulting structure is weak, and also the force exerted by the blades is decreasing according to the direction of introduction, so that the blockage is not stable, unless the cable is inserted fully. These solutions therefore do not offer control of the stable position of the cable.
    In US5911593 and JP59186967U are described connectors whose distance between sheets is decreasing in the direction of introduction of the cable, but the sheets are joined by its lower part, so that by increasing the depth of introduction between blades, the cutting force increases greatly and You can cut the cable, or leave it weakened.
    In US6036527 the sheets are not joined by their Bottom, at least not at the level of the edges, but the centers of rotation of the sheets are somewhat separated from the lower ends of the sheets. Even so, this design implies an increase in the force on the cable with the increase in depth.

    insulator displacement, comprising:
    two cutting and connection blades each provided with:
    > a section of centering and introduction of a cable; Y
    > a cutting edge that extends the centering and Introduction section,
    one base; Y
    one arm connecting each leaf to the base; so that they are defined:
    an introduction address between the sheets;
    a transverse direction, perpendicular to the direction of introduction and that goes from one sheet to another; a front direction perpendicular to the introduction and transverse directions, and corresponding to the axis of the cable when it is correctly inserted between the blades.
    Being these known characteristics, according to the present invention, in the absence of tensions caused by the introduction of a cable between the sheets, the cutting edges are inclined with respect to the direction of introduction and along the entire length of the edges, the projections of the cutting edges in a plane defined by the introduction and transverse directions are secants at an intermediate point of the cutting edges, and the cutting and connecting blades are not joined together at one end of the blades opposite the end of union with the sections of centering and introduction, but are attached to the arms of union so that the blades can be separated from each other according to the transverse direction along the entire length of the cutting edges.
    This structure allows to solve the inconveniences of the state of the art. By being able to separate the arms over their entire length and by arranging the crossed edges, a desired evolution of the force with depth can be easily achieved, that is, that the cutting force is controlled over the entire length of the cutting edges.
    In some embodiments, the connector is a die-cut and folded metal sheet.
    In some embodiments, the base and arms together define a U-section, that is to say that the section is a shape that has two ends internally joined so that an accessible cavity is configured from above. In this case the bottom of the U is the base, the leaves are attached to two arms at the top of some lateral edges of the arms and perpendicular to them, so that a volume of reception of a cable between the base is defined , the arms and a lower edge of the leaves.
    This structure provides a relative arrangement of arms, base and leaves that allows a movement of the leaves, by elastic deformation of the arms, which allows them to separate along the entire length of the cutting edges, and therefore adapt correctly to the diameter of the cable.
    In some embodiments, the centering and introduction sections have a circle arc contour.
    In some embodiments, the sheets and the base form an angle between 70 ° and 80 °.
    In some embodiments, the base is a section of U-folded sheet, the arms being extensions of the legs of the U so that the arms are in parallel planes, the leaves being extensions of the arms, the base being in the part opposite to the end of the leaves opposite to the end of union with the sections of centering and introduction.
    In some embodiments, the arms are cut in a sheet according to a circle-shaped contour in internal edges adjacent to the centering and insertion sections of a cable, so that an opening for the introduction of a cable is defined.
    In some embodiments, the connector consists of a closed metal strip, so that it has a tube section shape constituted by the base, the arms and the leaves. Preferably, the section of the connector is constituted by the base articulated with the arms by means of two curved sections, the other two ends of the arms being constituted by two semicircular sections followed by two curved sections ending in the leaves.

    Description of embodiments of the invention
    As shown in the figures, the present invention relates to a connector 1 by displacement of the insulator, comprising:
    two blades 2, 3 of cut and connection each provided with:
    > a section 21, 31 of centering and introduction of a cable W; Y
    > a cutting edge 22, 32 extending to the section 21, 31 centering and introduction, a base 4; Y
    one arm 5, 6 connecting each sheet 2, 3 to the base 4.
    In all the illustrated embodiments, the connector consists of a body obtained by trimming / stamping a metal sheet, to which an additional crushing, sharpening stage can be applied ... to give cutting edges edge. The laminar nature of the connector confers elasticity to the arms, so that the blades or blades can be separated when a cable is inserted between them. For very small IDCs such as those of 0.3 mm cable thickness it is not even necessary to reduce the section on the blades.
    As shown in Figures 1, and 5, the presence of the mentioned components allows defining the following reference, which will be useful for relating the characteristics of the connector:
    an input address X between sheets 2, 3; if carried out correctly, in the different embodiments according to the invention, the sheathed cable is arranged in the centering section and introduction to the height of the cable where it is desired to make the cut and the connection. Therefore, the direction of Introduction is that with respect to which the blades / blades 2, 3 are symmetrical, and the direction of Introduction is that which goes from the centering and introduction section towards the cutting and contact edges.
    a transverse direction Y, perpendicular to the direction of introduction and going from one sheet 2 to another 3;
    a front direction Z perpendicular to the X and transverse insertion directions Y, and that
    corresponds to the axis of cable W when it is correctly inserted between sheets 2, 3.
    Figures 1 to 10 show the different embodiments of the invention in steady state in the absence of inserted cable. The configuration in the absence of cable is different from the configuration with inserted cable, so the invention is described and claimed in the absence of tensions caused by the introduction of a cable between the sheets 2, 3.
    Under these conditions, and as can be clearly seen in Figures 1, 5 or 8, the cutting edges 22, 32 are inclined with respect to the direction of introduction X and along the entire length of the edges 22, 32.
    The inclination is not any, but it is the one that has the result that the projections of the cutting edges 22, 32 in a plane defined by the directions of Introduction X and transverse Y are drying at an intermediate point of the cutting edges 22 , 32. That is to say, although in some embodiments the case could be given
    that the cutting edges 22, 32 in the absence of cable are really secant, as for example in the figure
    10, more generally according to the invention, these edges intersect when the connector is viewed frontally. In practice, given the minimum separation that must be between edges to be able to cut the sheath of the cables, it can be assumed that they are effectively cut, as occurs in scissors.
    This characteristic, to fully define the invention, is complemented by the fact that the cutting and connecting blades 2, 3 are not joined together at one end of the blades 2, 3 opposite the end of union with the sections 21, 31 centering and introduction, as in the known connectors, but are connected to the

    joining arms 5, 6 so that the leaves 2, 3 can be separated from each other according to the transverse direction Y along the entire length of the cutting edges 22, 32.
    If theoretically in any pair of blades, although they are joined by their lower part, a separation occurs, because all the materials have a certain elasticity, according to the invention, the separation has a translation component, that is to say that the separation of the blades it is allowed, and in the absence of complementary stopper parts, and as can be seen in the figures, in any of the embodiments of the invention continuing to push the conductor beyond the lower end (lower considering the figures) would result in the cable would be released.
    As can be seen, considering the first embodiment, the effect of introducing a cable W in the connection 1 of the invention has the effect that as the cable is introduced the depth of introduction increases, and the lever arm is smaller as its going down. If the blades / blades 2, 3 were parallel, the force would decrease as the cable moves away from the axes of rotation of the arms 5, 6.
    This distancing occurs in the three embodiments of the invention, since in the third, although the section is constant, the stiffness of the arms will decrease when the blast outlet ends are reached (the blast outlet ends are opposite to the input ends, which are adjacent to the centering and introduction sections of the cable W).
    However, by arranging the blades as claimed, as the cable is introduced, a greater separation of the blades is forced, thus compensating the distance with respect to the axes of rotation of the elastic articulation arms. This effect is achieved by providing the inclination edges, but by making them interlaced and overlapping (according to their projection), the effects of pressure reduction (by turning axes away) and increased Pressure (per slope of the edges) is compensated.
    The person skilled in the art will achieve the evolution of the desired pressure by playing with the arrangement of the axes of rotation of the arms, which should never be close to the cut-off zone (as occurs in most of the connectors of the state of the technique), and with the slope of the leaves and their separation at the level of the entrance mouth. It is noted that these last two parameters determine the crossing point of the cutting edges, which in the illustrated embodiments is located in the middle of the edges.
    In other words, the connection 1 has the interlocking blades 2, 3, creating a triangular space so that the distance between blades decreases progressively from the entrance to the point where the occluded cable is left (Point located at depth h in Figure 12 ). The advantage is that the cutting force at the inlet is reduced, but as it advances / deepens, sufficient force is achieved to reach any cable core. In the state of the closest known art the blades 2, 3 have a more or less constant distance and the entry is made a reduction so that the input force is smaller but the force of the rest of the route is constant and does not always allow to reach to the core (obviously depending on the size of this), a technical problem that is solved by the present invention.
    The connection of the invention is designed to be integrated in a plastic housing provided with complementary elements such as the connection to other conductive elements, inlet ports for the cables W and especially a pressure element or lever P that allows the cable to be pressed for insertion between the sheets 2, 3 and also to serve as a stable blocking of the cable already stripped and connected to the sheets in the connection position, which is illustrated in Figure 12.
    Therefore, the cable is blocked above by the lever P, and below by the greater pressure due to the inclination and the blades. The block in the lower part can also be guaranteed by means of lateral stops, external when connected, facing the arms 5, 6. In any case, it has been possible to verify that the block provided by the slope of the leaves 2, 3 provides a better performance of the tension cables according to the Z direction.
    As illustrated in Figures 1 to 4, according to a first embodiment the base 4 and the arms 5, 6 together define a section. In this case the bottom of the U is the base 4, and the leaves 2, 3 are attached to two arms 5, 6 at the top of some lateral edges of the arms 5, 6 and perpendicular to these, so that defines a volume V for receiving a cable W between the base 4, the arms 5, 6 and a lower edge of the sheets 2, 3, as shown in Figure 11.
    As can be seen in Figure 1 and 11, the centering and introduction sections 21, 31 have a circle arc contour, which will be designed according to the diameter of the cables to be introduced.
    As can be seen in Figure 2, the blades 2, 3 form an angle between 70 ° and 80 ° with the X direction. This embodiment of the connection can be conceived with two pairs of blades. This double version would consist of making the mirror image of the elevation of Figure 2 on the right of this along a vertical axis,

    so that base 4 was common. Therefore, the sheets would have the inverted angle.
    Figures 11 and 12 illustrate the introduction and cutting process. As can be seen in Figure 11, the cable W is supported first, that is to say the outer surface of its sheath W2 on the centering and insertion sections 21, 31. Then, by means of a lever P the cable is pressed and a cable is introduced depth h until the blades 2, 3 come into contact with the core W1 of the cable, thus establishing the electrical contact.
    According to a second embodiment, illustrated in Figures 5 to 7, the base is a section of U-folded sheet, and the arms 5, 6 are two extensions of the legs of the U so that the arms are in parallel planes.
    In this case, the leaves 2, 3 are extensions of the arms 5, 6, and the base is opposite the end of the leaves 2, 3 opposite the end of union with the sections 21, 31 of centering and introduction.
    In this embodiment, the arms 5, 6 are cut along an outline 51, 61 in the form of a circular arc at internal edges adjacent to the centering sections 21, 31 of the centering and introduction of a cable W, so that an opening A is defined for the introduction of a W cable.
    A third embodiment, illustrated in Figures 8 to 10, consists of a closed metal strip, so that it has a tube section shape constituted by the base 4, the arms 5, 6 and the leaves 2, 3. In this case The section, shown in Figure 9, is constituted by the base 4 articulated with the arms 5, 6 by two curved sections 41, 42, the other two ends of the arms 5, 6 being constituted by two semicircular sections 52, 62 followed by two curved sections 53, 63 ending in sheets 2, 3.
    In the first and second embodiments, the axes of rotation of the arms are below the blades, considering figures 1 and 5, that is, that they are located after the sections 21, 31 of centering and Introduction, but at the end opposite to the direction of cut of the cable. In fact, in these cases the leaves are plots in two axes that would be located at the base 4 level and that would be perpendicular axes to the representation axis, that is, to an axis in the Z direction of Figures 1 and 5. That is, in these embodiments, the movement of the leaves 2, 3 are rotations in opposite directions, but since the axes are sufficiently far apart, the resulting effect is of translation between the leaves, that is to say that they are transferred with respect to the other.
    In contrast, in the embodiment of Figures 8 to 10, the axes of rotation of the arms, which could be considered as located near the corners 41 and 42, and perpendicular to the representation plane considering Figure 9, result in a substantially translational movement between sheets 2, 3.
    In this text, the word “understand” and its variants as “understanding”, etc. they should not be interpreted in an exclusive way, that is, they do not exclude the possibility that what has been described includes other elements, steps, etc.
    On the other hand, the invention is not limited to the specific embodiments that have been described but also covers, for example, the variants that can be made by the average person skilled in the art for example, in terms of the choice of materials, dimensions, components, configuration, etc., within what follows from the claims.
