Abstract

A plug-and-socket connector with an electrically conductive female contact for receiving a contact pin and for establishing an electrically conductive connection to the contact pin is described. According to implementations here, the female contact is accessible by an opening in the plug-and-socket connector. Further, a closure element for closing the opening is movably supported inside the female contact.

First claim

The invention claimed is:

1. A plug-and-socket connector comprising:
an electrically conductive female contact shaped to receive a contact pin, comprising a contact section at a distal end, and having structure that establishes an electrical connection to the contact pin, wherein the female contact is accessible by an opening in the plug-and-socket connector; and
a closure element for closing the opening, wherein the closure element is movably supported inside the female contact, wherein a distal section of the closure element increases in diameter in a plugging direction, and wherein the distal section engages the contact section, and wherein the contact section opens upon an advancing motion of the distal section during a plugging procedure of the contact pin.

2. The plug-and-socket connector according to claim 1 , wherein the closure element is supported by a first pretensioning device on an opposing section of the female contact, wherein the first pretensioning device presses the closure element in the direction of the opening.

3. The plug-and-socket connector according to claim 2 , wherein a second pretensioning device encompasses the contact section of the female contact in order to radially compress the contact section.

4. The plug-and-socket connector according to claim 3 , wherein the distal section of the closure element is constructed as an outer support for the second pretensioning device.

5. The plug-and-socket connector according to claim 4 , wherein the distal section of the closure element has an outside diameter which substantially corresponds to an outside diameter of the contact pin to be received and/or to an inside diameter of the opening.

6. The plug-and-socket connector according to claim 3 , wherein the distal section of the closure element has an outside diameter which substantially corresponds to an outside diameter of the contact pin to be received and/or to an inside diameter of the opening.

7. The plug-and-socket connector according to claim 1 , wherein the distal section decreases in diameter in the plugging direction after the increase in diameter.

8. The plug-and-socket connector according to claim 7 , wherein the female contact is arranged inside an insulating body in a stationary manner and wherein the opening is constructed in a sealing element comprising silicone and different from the insulating body.

9. The plug-and-socket connector according to claim 8 , wherein a material defining the opening, including the insulating body and the closure element, is constructed to be electrically insulating.

10. The plug-and-socket connector according to claim 1 , wherein the female contact is arranged inside an insulating body of the plug-and-socket connector in a stationary manner and wherein the opening is constructed in a sealing element comprising silicone and different from the insulating body.

11. The plug-and-socket connector according to claim 1 , wherein a material, defining the opening of an insulating body of the plug-and-socket connector and the closure element, is constructed to be electrically insulating.
