Abstract

A plug system comprising a plug part having at least one contact element, and comprising a counter plug part having at least one contact point on a contact carrier surface running approximately parallel to an insertion direction (S), wherein the plug part can be plugged in the plug-in direction (S) into the counter plug part, and the at least one contact element is in electrical contact with the contact point in an end position (II), wherein the counter plug part has a counter-pressure surface facing the contact carrier surface at least partially in a pressing direction (H) running transversely to the plug-in direction, wherein the contact carrier surface is retained on the counter plug part such that it moves in the plug-in direction (S) relative to the counter-pressure surface.

First claim

Thus, having described the invention, what is claimed is:

1. A plug system comprising a plug part with at least one contact element and a mating plug part comprising a contact carrier having a contact carrier surface with at least one contact point on the contact carrier surface running approximately parallel to a plugging direction (S), wherein the plug part can be plugged into the mating plug part in the plugging direction (S) and in an end position (II) the at least one contact element is in electrical contact with the contact point, wherein the mating plug part has a counter-pressure surface arranged, at least in portions, opposite the contact carrier surface in a pressing direction (H) oriented transversely to the plugging direction, wherein the contact carrier is held on the mating plug part so as to be moveable in the plugging direction (S) relative to the counter-pressure surface, thereby optimizing the wear behavior of contact partners contact element and at least one contact point on the contact carrier surface, wherein the plug part has at least one limit-stop surface against which a front surface of the contact carrier comes to bear during the plugging operation, wherein the contact carrier is pushed in the plugging direction (S) by the limit-stop surface during the plugging operation.

2. The plug system of claim 1 , wherein, when the plug part is plugged in, the contact carrier surface, together with the contact element resting substantially without pressure against, or arranged opposite the contact point, without play, can be displaced in the plugging direction (S) until the contact element is introduced into an intermediate space between the counter-pressure surface and the contact carrier surface and as a result is pressed against the contact point in the end position (II).

3. The plug system of claim 1 , wherein the at least one contact element is flexible.

4. The plug system of claim 3 , wherein the dimension of the contact element in the pressing direction (H) is greater, in the relaxed state, than the distance between the contact carrier surface and the counter-pressure surface opposite this, so that the at least one contact element can be clamped therebetween.

5. The plug system of claim 4 , wherein the at least one contact element in each case have a self-supporting first leaf spring part projecting in the plugging direction (S) with a first contact region intended to rest against the contact point and a second leaf spring part bent back from a front end of the first leaf spring part with a second contact region intended to rest against the counter-pressure surface in the end position (II).

6. The plug system of claim 3 , wherein the at least one contact element in each case have a self-supporting first leaf spring part projecting in the plugging direction (S) with a first contact region intended to rest against the contact point and a second leaf spring part bent back from a front end of the first leaf spring part with a second contact region intended to rest against the counter-pressure surface in the end position (II).

7. The plug system of claim 3 , wherein the at least one contact element is in the form of an elastically compressible leaf spring element.

8. The plug system of claim 1 , wherein the plug part has a plurality of contact elements arranged next to one another in a breadthwise direction (B), and/or the mating plug part has a plurality of contact points arranged next to one another in the breadthwise direction (B) on the contact carrier surface which, on plugging-in, in each case come into electrical contact with an associated contact element.

9. The plug system of claim 8 , wherein the plug part has five, ten, thirty, or more of contact elements arranged next to one another in a breadthwise direction (B), and/or the mating plug part has a plurality of contact points arranged next to one another in the breadthwise direction (B) on the contact carrier surface which, on plugging-in, in each case come into electrical contact with an associated contact element.

10. The plug system of claim 1 , wherein the mating plug part comprises at least one circuit board element, and/or the plug part comprises at least one contact element pair consisting of two contact elements arranged opposite one another in the pressing direction (H), between which the circuit board element can be introduced during the plugging operation.

11. The plug system of claim 10 , wherein a distance (A) between the contact elements of the at least one contact element pair substantially corresponds to the thickness of the circuit board elements.

12. The plug system of claim 11 , wherein the at least one circuit board element is arranged displaceably between two counter-pressure surfaces of the mating plug part which are provided in order to press the opposing contact elements of the contact element pairs of the plug part against the contact carrier surfaces of the circuit board element.

13. The plug system of claim 12 , wherein the circuit board elements in each case pass through intermediate spaces of a lamellar body containing the counter-pressure surfaces, wherein the lamellae of the lamellar body have ramp surfaces facing the plug part and/or running obliquely to the plugging direction (S).

14. The plug system of claim 13 , wherein the plug part has at least one limit-stop surface against which a front surface of the at least one circuit board element comes to bear during the plugging operation, wherein the circuit board element is pushed in the plugging direction (S) by the limit-stop surface during the plugging operation.

15. The plug system of claim 10 , wherein the mating plug part comprises two, three or more circuit board elements, in each case extending in the plugging direction (S) with two contact carrier surfaces which can in each case be inserted between contact element pairs until each contact element makes electrical contact with an associated contact point.

16. The plug system of claim 10 , wherein the at least one circuit board element is arranged displaceably between two counter-pressure surfaces of the mating plug part which are provided in order to press the opposing contact elements of the contact element pairs of the plug part against the contact carrier surfaces of the circuit board element.

17. The plug system of claim 16 , wherein the circuit board elements in each case pass through intermediate spaces of a lamellar body containing the counter-pressure surfaces, wherein the lamellae of the lamellar body have ramp surfaces facing the plug part and/or running obliquely to the plugging direction (S).

18. The plug system of claim 10 , wherein the plug part can be displaced from an intermediate position (I) in which the contact elements are in each case already correctly positioned opposite the associated contact points, but substantially free of contact pressure, into the end position (II) in which the contact elements are in each case clamped between a circuit board element and a counter-pressure surface and as a result are pressed against the associated contact point.

19. The plug system of claim 10 , wherein each contact carrier surface, in particular each circuit board element, is assigned at least one preloading element, against the preload of which the contact carrier surface can be displaced in the plugging direction (S).

20. The plug system of claim 19 , wherein a leaf spring comb is arranged behind the circuit board elements in the plugging direction and which has a plurality of spring elements ( 70 ).
