Abstract

Disclosed is a plug connector for positioning on a mating connector and for producing an electrically conductive connection. The plug connector comprises a guide means and a contact pin. The guide means is configured and positioned such that to produce the electrically conductive connection, contact bars of a contact socket of the mating connector can be guided by means of the guide means toward the contact pin, said contact bars encompassing the contact pin in a frictional engagement to establish electrical contact.

First claim

The invention claimed is:

1. A plug connector for positioning on a mating connector and for producing an electrically conductive connection, the plug connector comprising:
a guide element; and
a contact pin;
wherein the guide element is configured and positioned to produce the electrically conductive connection, a plurality of contact bars of a contact socket of the mating connector being arranged to be guided toward the contact pin via the guide element, said contact bars encompassing the contact pin in frictional engagement to establish electrical contact,
wherein the guide element is embodied as an annular spring, wherein the guide element has at least one interruption in a circumferential direction, and wherein the annular spring is disposed substantially coaxially to the central longitudinal axis of the contact pin.

2. The plug connector according to claim 1 , wherein the contact pin is mounted so as to be displaceable along its central longitudinal axis, and wherein a compression spring of the plug connector biases the contact pin in a plug-in direction of the plug connector.

3. The plug connector according to claim 1 , wherein the guide element has an inner diameter which is smaller than an outer diameter of the assigned contact socket of the mating connector.

4. The plug connector according to claim 1 , wherein the contact pin has an outer diameter that is smaller than an inner diameter of the assigned contact socket of the mating connector in the uncontacted state.

5. A mating connector for positioning on a plug connector and for producing an electrically conductive connection, the mating connector comprising:
a contact socket having at least two contact bars, wherein the at least two contact bars are configured and arranged to produce the electrically conductive connection, the contact bars being guided toward a contact pin of the plug connector via a guide element of the plug connector, said contact bars encompassing the contact pin in frictional engagement to establish electrical contact,
wherein the guide element is embodied as an annular spring, wherein the guide element has at least one interruption in a circumferential direction, and wherein the annular spring is disposed substantially coaxially to the central longitudinal axis of the contact pin.

6. The mating connector according to claim 5 , wherein the contact bars are configured and arranged such that the contact bars, which are introduced to the guide element, which is embodied as an annular spring and is disposed substantially coaxially to the central longitudinal axis of the contact pin, are forced toward the contact pin.

7. The mating connector according to claim 5 , wherein in the uncontacted state, the contact socket has an inner diameter that is greater than an outer diameter of the assigned contact pin of the plug connector.

8. The mating connector according to claim 7 , wherein the contact bars are configured and arranged such that the contact bars, which are introduced to the guide element, which is embodied as an annular spring and is disposed substantially coaxially to the central longitudinal axis of the contact pin, are forced toward the contact pin.

9. The mating connector according to claim 5 , wherein the contact bars are arranged coaxially to the central longitudinal axis of the contact socket, and wherein the outer diameter of the contact socket is greater than an inner diameter of the assigned guide element of the plug connector.

10. The mating connector according to claim 9 , wherein in the uncontacted state, the contact socket has an inner diameter that is greater than an outer diameter of the assigned contact pin of the plug connector.

11. The mating connector according to claim 9 , wherein the contact bars are configured and arranged such that the contact bars, which are introduced to the guide element, which is embodied as an annular spring and is disposed substantially coaxially to the central longitudinal axis of the contact pin, are forced toward the contact pin.

12. The mating connector according to claim 5 , wherein the contact socket is configured and positioned such that the contact pin of the plug connector, which is mounted so as to be displaceable along its central longitudinal axis in the plug connector and is forced via a compression spring in the plug-in direction, assumes a contact position with respect to the plug connector once the frictional engagement between the contact bars and the contact pin has been established.

13. The mating connector according to claim 12 , wherein the contact bars are arranged coaxially to the central longitudinal axis of the contact socket, and wherein the outer diameter of the contact socket is greater than an inner diameter of the assigned guide element of the plug connector.

14. The mating connector according to claim 12 , wherein in the uncontacted state, the contact socket has an inner diameter that is greater than an outer diameter of the assigned contact pin of the plug connector.

15. The mating connector according to claim 12 , wherein the contact bars are configured and arranged such that the contact bars, which are introduced to the guide element, which is embodied as an annular spring and is disposed substantially coaxially to the central longitudinal axis of the contact pin, are forced toward the contact pin.

16. A plug connector system for producing an electrically conductive connection, the plug connector system comprising:
a plug connector comprising a guide element and a contact pin; and
a mating connector for positioning on the plug connector and for producing an electrically conductive connection with the plug connector, the mating connector comprising a contact socket having at least two contact bars;
wherein the guide element of the plug connector is configured and positioned to produce an electrically conductive connection with the mating connector, at least two of the contact bars of the contact socket of the mating connector being configured and arranged to be guided toward the contact pin via the guide element, the contact bars encompassing the contact pin in frictional engagement to establish electrical contact,
wherein the guide element is embodied as an annular spring, wherein the guide element has at least one interruption in a circumferential direction, and wherein the annular spring is disposed substantially coaxially to the central longitudinal axis of the contact pin.

17. The plug connector system of claim 16 , wherein, with regard to the plug connector:
the contact pin is mounted so as to be displaceable along its central longitudinal axis, and wherein a compression spring of the plug connector biases the contact pin in a plug-in direction of the plug connector; and
the guide element is embodied as an annular spring, and wherein the annular spring is disposed substantially coaxially to the central longitudinal axis of the contact pin.

18. The plug connector system of claim 17 wherein, with regard to the mating connector, the contact socket is configured and positioned such that the contact pin of the plug connector, which is mounted so as to be displaceable along its central longitudinal axis in the plug connector and is forced via a compression spring in the plug-in direction, assumes a contact position with respect to the plug connector once the frictional engagement between the contact bars and the contact pin has been established.

19. The plug connector system of claim 18 wherein the contact bars are configured and arranged such that the contact bars, which are
