Abstract

Official abstract text for this publication.

A connector device including: a plug which has a plug housing and at least one electrical plug contact that is held so as to be insulated in the plug housing; and a socket which has a socket housing and a socket contact. The socket housing has an electrically insulating plug channel for receiving the plug contact, in which plug channel the socket contact is located. A sleeve is rotatably arranged on the plug housing or the socket housing. A slotted guide arrangement is operatively disposed between the sleeve, the plug housing and the socket housing. A slotted guide of the slotted guide arrangement has a separating portion having a slope relative to a circumferential direction. After the separating portion in an opening direction, a delay portion is located, which has a smaller slope than the separating portion.

First claim

Opening claim text (preview).

The invention claimed is: 1. A plug connection device, comprising: a plug comprising a plug housing and at least one electrical plug contact held in the plug housing in an insulated manner, a socket comprising a socket housing and a socket contact, wherein the socket housing comprises a plug channel configured in an electrically insulated manner in which the socket contact is arranged, for receiving the at least one electrical plug contact, wherein a sleeve is rotatably arranged on the plug housing or the socket housing, a slotted guide arrangement arranged to be effective between the sleeve, the plug housing and the socket housing, a guide slot having a separation section and a deceleration section arranged after the separation section in an opening direction, the separation section having an inclination relative to a circumferential direction and the deceleration section having a lower inclination relative to the circumferential direction than the inclination of the separation section, wherein the plug and the socket comprise a latch device having a latch section and a first counter latch section and a second counter latch section and the latch section is brought into engagement with the second counter latch section during guidance of a cam through the separation section. 2. The plug connection device according to claim 1 further comprising a spring mechanism that is arranged to be effective between the sleeve, the plug housing and the socket housing and the spring mechanism is configured to store movement energy during movement of the sleeve for separation of the plug and the socket in order to release the movement energy during a continued separation movement. 3. The plug connection device according to claim 1 , wherein the socket or the plug comprises a holding cavity for receiving a holding extension of the plug or the socket. 4. The plug connection device according to claim 3 , wherein the latch section is arranged on the holding extension and wherein the first counter latch section is arranged at a first position and the second counter latch section is arranged at a second position in the holding cavity. 5. The plug connection device according to claim 2 , wherein during guidance of the cam through the separation section the at least one electrical plug contact and the socket contact are driven away from one another at least partly due to energy released from the spring mechanism. 6. The plug connection device according to claim 2 , wherein at a location along a separation path of the plug and the socket a force for separating the at least one electrical plug contact and the socket contact applied by the spring mechanism is larger than a friction force between the latch section and a support of the first counter latch section and the second counter latch section. 7. The plug connection device according to claim 2 , wherein a cavity is formed between the separation section and the deceleration section in which the cam engages, during an explosion between the at least one electrical plug contact and the socket contact, in order to inhibit or temporarily block a further movement of the sleeve in the opening direction. 8. The plug connection device according to claim 7 , wherein if the cam has engaged the cavity, the cam can be brought into disengagement with the cavity against a spring force of the spring mechanism, so that at least the spring force has to be applied for movement of the sleeve in the opening direction. 9. The plug connection device according to claim 1 , further comprising a locking section of the guide slot, wherein the separation section is arranged after the locking section in the opening direction, wherein the locking section blocks a separation movement of plug contact relative to the socket contact. 10. The plug connection device according to claim 1 , wherein the guide slot comprises a release section that allows a further movement of the at least one electrical plug contact and the socket contact relative to each other in a separation direction. 11. A plug or socket for a plug connection device according to claim 1 . 12. The plug connection device according to claim 2 , wherein the socket or the plug comprises a holding cavity for receiving a holding extension of the plug or the socket. 13. The plug connection device according to claim 12 , wherein the latch section is arranged on the holding extension and wherein the first counter latch section is arranged at a first position and the second counter latch section is arranged at a second position in the holding cavity. 14. The plug connection device according to claim 13 , wherein during guidance of the cam through the separation section the at least one electrical plug contact and the socket contact are driven away from one another at least partly due to energy released from the spring mechanism. 15. The plug connection device according to claim 14 , wherein at a location along a separation path of the plug and the socket a force for separating the at least one electrical plug contact and the socket contact applied by the spring mechanism is larger than a friction force between the latch section and a support of the first counter latch section and the second counter latch section. 16. The plug connection device according to claim 15 , wherein a cavity is formed between the separation section and the deceleration section in which the cam engages, during an explosion between the at least one electrical plug contact and the socket contact, in order to inhibit or temporarily block a further movement of the sleeve in the opening direction.
