Abstract

An electrical plug connector for a vehicle comprises a plug with a plug casing in which a contact chamber is formed, an electrical contact part arranged in the contact chamber, a locking bolt for releasably attaching a plug-in contact to the contact part, and a socket to be plugged with the plug, a socket casing and a plug-in contact attached thereto. The plug connector has a locking slide attachable to the plug casing that is mounted on the casing for displacement at least into a locking position in a direction transverse to the plugging direction of the plug, to lock the plug to the socket. The locking slide has a guide slot extending substantially transversely to the plugging direction and having an inclined plane to guide the locking bolt of the contact part as it is moved into the locking position.

First claim

What is claimed is:

1. An electrical plug connector for a vehicle, comprising:
a plug comprising a plug casing having a contact chamber;
an electrical contact part arranged in the contact chamber, the contact part comprising a locking bolt for releasably attaching a plug-in contact to the contact part;
a socket configured for coupling to the plug, the socket comprising a socket casing and the plug-in contact, the socket receiving the plug in a first direction; and
a locking slide attached to the plug casing, the locking slide comprising a guide slot extending substantially transversely to the first direction, the guide slot having an inclined plane for guiding the locking bolt of the contact part in a displacement direction transverse to the first direction into a locking position, the locking position locking the plug to the socket.

2. The plug connector according to claim 1 , wherein the guide slot comprises a first linear segment for receiving the locking bolt and a second linear segment, the inclined plane of the guide slot being arranged between the first linear segment and the second linear segment.

3. The plug connector according to claim 1 , wherein the inclined plane comprises an angle of inclination of approximately 30° to 60°.

4. The plug connector according to claim 1 , wherein the inclined plane comprises an angle of inclination of approximately 45°.

5. The plug connector according to claim 1 , wherein the locking slide is configured to lock the contact part in the contact chamber in a secondary locking position upstream of the locking position.

6. The plug connector according to claim 1 , wherein the locking slide comprises a secondary locking rib on a side facing the plug casing, the secondary locking rib being configured to lock the contact part in the contact chamber.

7. The plug connector according to claim 1 , wherein the plug casing comprises a first longitudinal rib extending in the first direction and a second longitudinal rib arranged parallel to the first longitudinal rib, the first and second longitudinal ribs configured to interact with the locking slide.

8. The plug connector according to claim 7 , wherein the locking slide comprises a detent lug configured to engage with at least one of the first longitudinal rib or the second longitudinal rib.

9. The plug connector according to claim 8 , wherein the detent lug engages behind the second longitudinal rib viewed in the displacement direction, in a secondary locking position upstream of the locking position.

10. The plug connector according to claim 8 , wherein the detent lug engages behind the first longitudinal rib viewed in the displacement direction, in an installation position upstream of the locking position.

11. The plug connector according to claim 10 , wherein the contact chamber is open in the installation position.

12. The plug connector according to claim 7 , wherein the locking slide comprises a resilient position-assurance arm engaged with at least one of the first longitudinal rib or the second longitudinal rib, the position-assurance arm being releasable from the engaged longitudinal rib by deflection to permit displacement into the locking position.

13. The plug connector according to claim 12 , wherein the socket casing comprises an unlocking rib configured to release the position-assurance arm from the engaged longitudinal rib.

14. The plug connector according to claim 13 , wherein the unlocking rib is guided between the first and the second longitudinal ribs when the plug is connected to the socket.

15. The plug connector according to claim 1 , wherein the socket and the coupled plug are at least partly encased in a protective housing.

16. The plug connector according to claim 1 , wherein the plug connector is a high-voltage plug connector.

17. An electrical plug for a high-voltage plug connector system in a vehicle, the electrical plug comprising:
a plug casing having a contact chamber for encompassing at least part of an electrical contact part, the electrical part comprising a locking bolt; and
a locking slide attached to the plug casing, the locking slide comprising a guide slot extending substantially transversely to a first direction, the guide slot having an inclined plane for guiding the locking bolt in a displacement direction transverse to the first direction into a locking position, the locking position locking the plug to a socket configured to receive the plug in the first direction.

18. The electrical plug according to claim 17 , wherein the guide slot comprises a first linear segment for receiving the locking bolt and a second linear segment, the inclined plane of the guide slot being arranged between the first linear segment and the second linear segment.

19. The electrical plug according to claim 17 , wherein:
the plug casing comprises a first longitudinal rib extending in the first direction and a second longitudinal rib arranged parallel to the first longitudinal rib, the first and second longitudinal ribs configured to interact with the locking slide; and
the locking slide comprises a detent lug configured to engage with at least one of the first longitudinal rib or the second longitudinal rib.

20. The electrical plug according to claim 19 , wherein the locking slide comprises a resilient position-assurance arm engaged with at least one of the first longitudinal rib or the second longitudinal rib, the position-assurance arm being releasable from the engaged longitudinal rib by deflection to permit displacement into the locking position.
