• the sleeve 20 is now rotated to pass the cam 28 through the delay section 22b. However, further insertion of the holding extension 33 into the holding receptacle 32 is only possible against the resistance between the latching section 34 and the second counter-latching section 36 .
• the force for disengaging the latching section 34 and the second counter-latching section 36 in the joining direction can, as with a thread, due to the gearing behavior between the cam 28 and the separating section 22b, by rotating the sleeve 20 via the plug 13 onto the retaining extension 33 be transmitted. Alternatively or additionally, this movement can be at least supported by pressing the plug 13 in the joining direction.
• the spring accumulator 30 with the spring element 30a, 30b mentioned above in connection with the description of the separation or another spring element can help to ensure that the contact between the plug contact 15 and socket contact 16a is made abruptly.
• a connector device 10 is provided with a plug 13, which has a plug housing 14 and at least one electrical plug contact 15 held insulated in the plug housing 14, and a socket 11, which has a socket housing 12 and a socket contact 16a , disclosed.
• the socket housing 12 has an electrically insulating plug channel for receiving the plug contact 15, in which plug channel the socket contact 16a is arranged.
• a sleeve 20 is rotatably arranged on the plug housing 14 or the socket housing 12 . Between the sleeve 20, the plug housing 14 and the socket housing 12, a connecting link arrangement 21 is effectively arranged.
• a link 22 of the link arrangement 21 has a separating section 22b with a pitch relative to a circumferential direction U.
• a delay section 22c is arranged, which has a smaller gradient than the separating section 22b.
