Description

TECHNICAL FIELD

[0001] The present invention relates to a connector according to the preamble of claim 1. STATE OF THE ART

[0002] DE 20 2013 000 969 U1 discloses a connector comprising a plurality of contact elements held in a housing by a locking element. Each of the contact elements can be individually inserted into a corresponding receptacle.

[0003] The disadvantage of DE 20 2013 000 969 U1 is that the contact elements can only be inserted and removed again with a comparatively large amount of force.

[0004] GB 1 491 217 discloses another connector in which the contact elements are held in place by spring clips. The spring clips are held in their clamped position by a locking element.

[0005] GB 1 491 217 has the advantage over DE 20 2013 000 969 U1 that the contact element can be more easily removed from or inserted into the receptacle. However, inserting or removing the contact element is complex because the locking element also has to be manipulated.

[0006] Another disadvantage is that the articles according to DE 20 2013 000 969 U1 and GB 1 491 217 are complex to manufacture and assemble, particularly with regard to their complex mechanical design with multiple parts.

[0007] From WO 2013 / 042376 A1, a connector has become known which has a plurality of contact elements which are held in a housing, wherein a holding web can be moved from a clamping position into a release position by deformation. PRESENTATION OF THE INVENTION

[0008] Based on this prior art, the invention is based on the object of providing a connector that overcomes the disadvantages of the prior art. In particular, a preferred object is to provide a connector whose contact elements are easy to install and remove.

[0009] This object is achieved by the subject matter of claim 1. Accordingly, a plug-in connector comprises a contact carrier and a plurality of contact elements mounted in the contact carrier, which contact elements extend along a central axis. The contact carrier has a front wall and a rear wall, which are connected to one another via side walls, wherein the front wall, rear wall, and the side walls define a receiving space. At least one retaining web extends from the front wall to the rear wall through the receiving space. There may also be several retaining webs running parallel to one another. The at least one retaining web has a front fastening section and a rear fastening section, as well as a clamping section located between the fastening sections.The at least one retaining web has at least one clamping structure in the clamping section, with which a contact element is clamped in a space between two adjacent retaining webs and / or with which a contact element is held in a space between a retaining web and one of the side walls. At least one of the fastening sections has the structure of a solid-state joint, such that the retaining web can be moved from a clamping position to a release position upon insertion and / or removal of the contact element by elastic deformation of the solid-state joint.

[0010] The arrangement of the flexure joint allows for easy installation and removal of the contact elements. It creates predetermined points that can be elastically deformed during installation and removal.

[0011] The arrangement of the solid-state joint creates a deterministic joint, which makes it possible for the installation or removal of a contact element to always take place under the same conditions.

[0012] In other words, the retaining bar is deflected from the clamping position into the release position.

[0013] The term "flexible joint" refers to a joint that allows relative movement between the front wall and the clamping section, or between the rear wall and the clamping section. When a force is applied, the flexible joint is elastically deformed from the clamped position to the released position and returns to the clamped position when the force is removed. The flexible joint can be deformed by bending or torsion. A combination of bending and torsional deformation is also conceivable.

[0014] The term "held" refers to a mechanical retention of the contact element in the gap. For example, the contact element is clamped and / or locked into place.

[0015] Preferably, a plurality of retaining webs are present in the receiving space so that several intermediate spaces can be provided for the contact elements.

[0016] The contact carrier is preferably made of plastic, wherein the contact carrier is preferably manufactured by an injection molding process.

[0017] The contact element is preferably an electrical contact element or a pneumatic contact element or a hydraulic contact element or an optical contact element.

[0018] During the movement of the retaining web, the clamping section preferably undergoes deformation, in particular elastic deformation, in addition to the at least one solid-state joint. The degree of deformation of the clamping section is preferably smaller than the degree of deformation of the at least one solid-state joint.

[0019] Preferably, the solid-state joint has a cross-sectional area which is smaller than the cross-sectional area of the clamping section.

[0020] This design ensures that the deformation actually occurs in the flexure joint when the force is applied. The clamping section is therefore more robust than the flexure joint and is therefore not deformed or is only slightly deformed.

[0021] Preferably, the cross-sectional area of the solid-state joint corresponds to 15% to 75%, in particular 25% to 60%, of the maximum cross-sectional area of the clamping section.

[0022] The front fastening portion is preferably integrally formed on the front wall and the rear fastening portion is preferably integrally formed on the rear wall.

[0023] Preferably, the extension of the retaining web between the front wall and the rear wall is defined as length, the extension between two adjacent spaces as width and the extension transverse to the length as height, wherein the width of the clamping section is equal to the width of the solid joint and wherein the height of the clamping section is greater than the height of the solid joint.

[0024] This design allows for a solid-body joint that is easy to deform.

[0025] Preferably, the clamping section extends vertically on both sides of the flexure joint. Preferably, the width is smaller than the height.

[0026] When actuated, the flexure joint preferably undergoes a torsional movement about an axis running parallel to the central axis of the contact element and centrally through the flexure joint, as well as a deflection movement away from the contact element or perpendicular to the axis. The axis preferably runs through the center of the cross-sectional area of the flexure joint. The cross-sectional area of the flexure joint in the direction of said axis is preferably constant.

[0027] Preferably, the transition between the solid-state joint and the front wall and / or between the solid-state joint and the rear wall is rounded.

[0028] The rounding allows stress peaks that occur during deformation to be easily dissipated.

[0029] Preferably, the clamping section has an actuating tab via which a force can be exerted on the holding web such that the holding web can be moved from the clamping position into the release position.

[0030] Preferably, the actuating tabs of two adjacent retaining webs are located at the same position on the respective retaining webs, viewed in the direction of the retaining web, such that the two retaining webs are moved away from each other from the clamping position into the release position by a tool that can be positioned between the actuating tabs and acts via the two actuating tabs.

[0031] Preferably, the side wall has an actuating tab or the side wall provides an actuating tab, wherein the adjacent retaining web is moved away from the side wall from the clamping position into the release position by means of a tool acting on the actuating tab of the side wall and the actuating tab of the retaining web adjacent to the side wall.

[0032] Preferably, the actuating tab extends over the entire length or part of the length of the clamping section.

[0033] Preferably, the contact element is substantially cylindrical on the outside, wherein the contact element has at least one recess into which the clamping structure engages.

[0034] According to the invention, the clamping structure has at least one hook, wherein the hook has a concave curve for receiving the contact element, and wherein the concave curve, viewed in cross-section transverse to the central axis, has substantially the shape of a circular segment, in particular substantially the shape of a quarter circle.

[0035] The hook therefore grips the contact element and holds it in the gap.

[0036] According to the invention, two hooks are arranged on two adjacent retaining webs or the side wall opposite one another with respect to the intermediate space and form a pair of hooks, wherein one hook engages the contact element from below with respect to the central axis and the other hook engages the contact element from above with respect to the central axis.

[0037] Preferably, the hooks of a hook pair grip the contact element at different angles. This makes it easier to release the contact element.

[0038] Preferably, at least two pairs of hooks are arranged offset from one another in the direction of the central axis of the contact element or the holding web or the side wall, wherein the length of the hooks between the individual pairs of hooks is the same or different.

[0039] The offset arrangement of two pairs of hooks can improve the bearing of the contact element.

[0040] Preferably, the clamping structure further comprises a securing element on the retaining web or on the side wall, which provides a stop with respect to a movement of the contact element in the direction of the central axis of the contact element.

[0041] The securing element protrudes, for example, into one of the recesses mentioned.

[0042] Preferably, the side walls have a clamping structure on the surface facing the receiving space, which is substantially identical or similar to the clamping structure on the holding webs.

[0043] Preferably, the front wall and the rear wall each have an opening for each contact element, through which access to the contact element is provided. Preferably, two adjacent openings are offset from each other, both downwards and upwards. This also offsets the contact elements. The clamping structures that protrude into two adjacent receiving spaces are also offset from each other.

[0044] Particularly preferably, the contact element is an electrical contact element and has a front contact section designed as a socket or pin. Furthermore, the contact element has a rear contact section designed for connection to a cable.

[0045] The contact carrier preferably has clamping tabs on the outside with which the contact carrier can be clamped to a holding frame.

[0046] Preferably, a first contact carrier has a receptacle in the area of the front wall into which a guide section of another contact carrier can be inserted. The receptacle can also serve as protection for the parts of the contact elements that project into the receptacle.

[0047] Preferably, the further contact carrier has a guide section in the region of the front wall and in a partial region of the side wall, which guide section can be inserted into a receptacle of a further contact carrier.

[0048] Further embodiments are specified in the dependent claims. BRIEF DESCRIPTION OF THE DRAWINGS

DESCRIPTION OF PREFERRED EMBODIMENTS

[0050] In the Figures 1 to 7 Various views of a connector 1 are shown. In the embodiments shown, the connector is depicted as a socket side 1a or a pin side 1b. The essential features of the connector 1 are essentially identical on the socket side 1a and the pin side 1b. In the following, only connector 1 is referred to, whereby this refers equally to the socket side 1a and the pin side 1b.

[0051] The connector 1 comprises a contact carrier 2 and a plurality of contact elements 3 mounted in the contact carrier 2. The contact elements 3 extend along a central axis M. The contact elements 3 are shown here as electrical contact elements 3. However, pneumatic, hydraulic, or optical contact elements can also be used.

[0052] The contact carrier 2 has a front wall 4 and a rear wall 5, which are connected to one another via side walls 6. The front wall 4, the rear wall 5 and the side walls 6 define a receiving space 7. The contact elements 3 are located in the receiving space 7. Furthermore, a plurality of holding webs 8 extend through the receiving space 7 from the front wall to the rear wall 5. The holding webs 8 each have a front fastening section 9 and a rear fastening section 10 as well as a clamping section 11 located between the fastening sections 9, 10. The contact element 3 is held in the receiving space 7 via the clamping section 11.

[0053] The front fastening section 9 is integrally formed on the front wall 4, and the rear fastening section 10 is integrally formed on the rear wall 5. This means that the fastening sections 9, 10 are integrally connected to the front wall 4 and the rear wall 5, respectively. Likewise, the front wall 4 and the rear wall 5 are integrally connected to the side walls 6. The retaining webs 8 have at least one clamping structure 12 in the clamping section 11. The clamping structure 12 holds a contact element 3 clamped in a space 14 between two adjacent retaining webs 8 or in the space 14 between a retaining web 8 and the side wall 6.

[0054] The at least one fastening section 9, 10 has the structure of a solid-state joint 15. In the embodiment shown, both fastening sections 9, 10 have the shape of a solid-state joint 15. The solid-state joint 15 is, as shown in the Figures 3a and 3bAs can be clearly seen, the retaining web 8 is designed such that the retaining web 8 can be moved from a clamping position to a release position by elastic deformation of the solid-state joint 15 upon insertion and / or removal of the contact element 3. The actuation can be carried out, for example, by means of a tool W, as shown in the Figure 2 shown.

[0055] The arrangement of the flexural joint 15 provides a deterministic or specific joint. This makes it possible for the contact element 3 to be installed and removed under the same conditions every time. Furthermore, the flexural joint provides the advantage that a mechanical joint is present, which accordingly enables relative movement between the front wall 4 and the clamping section 11 or between the rear wall 5 and the clamping section 11. When a force is applied, the flexural joint 15 is elastically deformed and thus moves the retaining web 8 or parts of the retaining web 8 from the clamped position to the release position. Depending on its design, the retaining web 8 can also be elastically deformed. Preferably, however, the flexural joint 15 and the retaining web 8 are defined such that the majority of the deformation occurs in the flexural joint.

[0056] When the force is removed, the retaining web 8 and the flexure joint 15 return to the clamped position. This is therefore an elastic deformation. The flexure joint 15 is subjected to a combined movement of bending and torsion and deforms accordingly. Depending on its design, the flexure joint can also be subjected to only bending or only torsion.

[0057] Of the Figures 3a and 3b It can be clearly seen that the flexural joint 15 has a cross-sectional area that is smaller than the cross-sectional area of the clamping section 11. This means that the flexural joint 15 is tapered compared to the clamping section 11.

[0058] Particularly preferably, the cross-sectional area of the solid-state joint corresponds to 15 to 65%, in particular 25 to 60% of the maximum cross-sectional area of the clamping section 11. The maximum cross-sectional area of the clamping section 11 is defined in a region in which the clamping structure 12 is not present.

[0059] The extension of the retaining web 8 between the front wall 4 and the rear wall 5 is defined as the length. The extension of the retaining web 8 between two adjacent gaps 14 is defined as the width. The extension of the retaining web 8 transverse to the length of the retaining web 8 is defined as the height. The width of the clamping section is essentially equal to the width of the flexure joint 15. This means that, apart from the clamping structure 12, the retaining web 8 has an essentially constant width between the front wall 4 and the rear wall 5.

[0060] The height of the clamping section 11 is greater than the height of the flexural joint 15. As a result, the clamping section 11 is designed with greater robustness than the flexural joint 15, which is advantageous for the movement of the flexural joint 15.

[0061] The clamping section 11 extends vertically on both sides of the flexure joint 15. This means that the clamping section 11 extends both above and below the flexure joint 15.

[0062] When actuated, the flexure joint 15 in the illustrated embodiment undergoes a torsional movement and a deflection movement. The torsional movement occurs about an axis A running parallel to the central axis M of the contact element 3 and centrally through the flexure joint 15. The deflection movement occurs transversely to the axis A. As already mentioned, the axis A runs parallel to the central axis M of the contact element 5 and centrally through the flexure joint 15 and through the retaining web 8.

[0063] Of the Figures 3a and 3b It can also be seen that the transition from the flexural hinge 15 to the front wall 4 and the transition from the flexural hinge 15 to the rear wall 5 are rounded with a curve 16. This design of the transition has the advantage that stress peaks resulting from the elastic deformation of the flexural hinge 15 can be easily introduced into the front wall 4 and the rear wall 5, respectively.

[0064] The clamping section 11 has, as shown in the figures, in particular the Figure 2 , shown, an actuating tab 17. Via the actuating tab 17, which protrudes from the actual clamping section 11, a force can be exerted on the holding web 8 and on the solid-state joint 15. The force can be exerted in such a way that the holding web 8 is moved from the clamping position into the release position. In the embodiment shown, a tool W can be placed between two adjacent holding webs 8, wherein by actuating the tool, in particular by twisting the tool W, a force can then be exerted on the actuating tabs 17 of the two adjacent holding webs 8. In the embodiment shown, the tool W is a screwdriver.

[0065] The actuating tabs 17 of two adjacent retaining webs 8 are essentially always in the same position when viewed in the direction of the retaining web 8, so that the two retaining webs can be moved away from each other from the clamping position into the release position by the tool W which can be positioned between the actuating tabs 17 and acts via the actuating tabs 17.

[0066] From all figures, it can be clearly seen that the contact element 3 is essentially cylindrical on the outside. The contact element 3 has at least one recess 18 into which the clamping structure 12 engages.

[0067] With reference to the Figures 3a , 3b , 4 , 5 and 7 Details of the clamping structure 12 are now explained in more detail.

[0068] According to the invention, the clamping structure comprises at least one hook 19, wherein the hook 19 has a concave curve 20 for receiving the contact element 3. The concave curve 20 only partially surrounds the contact element when viewed in cross-section around the central axis M. In the embodiment shown, the concave curve 20 has the shape of a quarter circle.

[0069] According to the invention, two hooks 19 are arranged on each of two adjacent retaining webs 8. The two hooks 19 are arranged opposite one another with respect to the intermediate space 14. These two hooks 19 form a pair of hooks. One hook 18 surrounds the contact element 3 from below and the other hook 19 surrounds the contact element 3 from above. This encircling is Figure 7shown accordingly. The hooks 19 of a hook pair hold the contact element 3 in the gap 14. Furthermore, the hooks 19 can also act as a positioning aid for the contact element 3.

[0070] Preferably, the hooks 19 are designed so that the contact element 3 is mounted in a floating manner. This means that the contact element is mounted in the intermediate space 14 so that it can be easily moved.

[0071] In the embodiment shown, as shown in the Figures 3a and 3b As clearly shown, two pairs of hooks are arranged offset from one another in the direction of the central axis M of the contact element 3 and in the direction of the retaining web 8. A total of four hooks 18 are arranged per space 14. The length of the hooks 18 between the individual pairs of hooks can be the same or different. This means that the contact element 3 is essentially encompassed by two pairs of hooks at two points.

[0072] Furthermore, the clamping structure has a securing element 21 on the retaining web 8. The securing element 21 is designed as a protrusion extending away from the retaining web 8 and provides a stop with respect to the movement of the contact element 3 in the direction of the central axis M of the contact element 3. This stop effect is Figure 5 shown. The securing element 21 engages in a recess 18 on the contact element 3.

[0073] The side walls 6 also have a clamping structure 12 on the surface 22 facing the receiving space 7. The clamping structure 12 is essentially identical or similar to the clamping structure 12 on the retaining webs 8. This means that in the present case, corresponding hooks 19 and the securing element 21 are also present.

[0074] The front wall 4 and the rear wall 5 have an opening 23 for each contact element. Access to the contact element 3 can be created through this opening 23.

[0075] In the Figure 6 It is shown that the openings 23 are not located on the same axis, but are offset upwards and downwards from each other. This arrangement has the advantage that the retaining webs can be deflected with less force. Furthermore, the distance between two adjacent contact elements is increased, which in turn has the advantage of preventing electrical crosstalk between the two contact elements.

[0076] The contact element shown in the figures is an electrical contact element. The electrical contact element has a front contact section 24 and a rear contact section 25. In the socket side 1a, the front contact section 24 is designed as a socket part, and in the pin side 1b, the front contact section 24 is designed as a pin part. When connected, the pin part protrudes into the socket part. The rear contact section 25 serves to accommodate a cable.

[0077] The contact carrier 2 has, as shown in all figures, clamping tabs 26 on the outside. With these clamping tabs, the contact carrier 2 can be clamped to a holding frame 27. An example of a holding frame 27 is shown in the Figure 8shown. The holding frame 27 has a structure that allows the contact carrier 2 to be clamped to the holding frame 27 using the external clamping tabs 26. In the embodiment shown, additional connector parts are also shown.

[0078] Furthermore, the contact carrier 2 of the pin side 1b has a receptacle 28 in the area of the front wall 4. The receptacle 28 provides a guide for a guide section 29 of the contact carrier 2 of the socket side 1a. The contact carrier 2 of the socket side 1a has a guide section 29 in the area of the front wall 4 and in a partial area of the side wall 6, which can then be inserted into the receptacle 28 of the contact carrier 1 of the pin side 1b.
