When the first sleeve 21 and the female connection assembly 100 are not clamped in place, the male connection assembly 200 is separated from the female connection assembly 100 under the elastic force of the elastic member 13, so as to detect whether the male connection assembly 200 and the female connection assembly 100 are assembled in place. In the embodiment, the elastic member 13 is a compression spring.

As can be seen from fig. 1 and fig. 5 to 7, optionally, the second sleeve 14 is disposed in the offset groove along the first direction, the connector device further includes a TPA12, one end of the TPA12 is connected to the second sleeve 14, and the first sleeve 21 can be sleeved on the other end of the TPA12 and slidably disposed relative to the TPA12, so as to not only guide the first sleeve 21 to slide in the offset groove, but also limit the sliding displacement of the first sleeve 21. Further, a female terminal is disposed in the second sleeve 14, and when the male connection assembly 200 and the female connection assembly 100 complete the mutual connection, the male terminal contacts with the female terminal to complete the electrical connection of the two to-be-connected components.

Specifically, the first suspension arm 112, the second suspension arm 15 and the third suspension arm 113 are properly lifted during the mating process of the male-end connection assembly 200 and the female-end connection assembly 100. Accordingly, the first, second, and

third suspension arms

112, 15, and 113 are made of an elastically deformable material.

As shown in fig. 2, further alternatively, a stop block 114 is disposed on the third suspension arm 113, and when the CPA11 is located at the first position, the stop block 114 abuts against the short arm to limit the movement of the CPA11 in the first direction.

The second CPA is provided with a third cantilever 113, two first cantilevers 112 and two positioning pillars 111, and the two first cantilevers 112 and the two positioning pillars 111 are both symmetrically arranged along the central axis of the third cantilever 113. The provision of two CPA11 allows for a targeted selection of CPA11 during production based on the structure within the female-end connection assembly 100. In order to improve the detection effect, two or more elastic members 13 are provided in the female connection assembly 100. Illustratively, when two elastic members 13 are provided in the female terminal connection assembly 100, two first CPAs or one second CPA should be selected.
