Wherein the first bearing part 41 is arranged close to the first end face 20 and far from the second end face 30.
In the embodiment of the present invention, the connector 100 is connected to the connecting seat 200 through the first connecting assembly 40, and the connector 100 can be pressed on the first end surface 20, so that in the process that the connector 100 enters the connecting seat 200 along the direction from the first end surface 20 to the second end surface 30, the free end 422 of the guiding elastic portion 42 can be deformed under the action of the guiding portion 242 of the connecting seat 200, and the connector 100 is driven to rotate along the direction parallel to the first end surface 20, so that the first bearing portion 41 is disposed between the guiding inclined surface 2421 and the second bearing portion 241 and abuts against the second bearing portion 241, so as to prevent the connector 100 from being separated from the connecting seat 200, meanwhile, the free end 422 of the guiding elastic portion 42 still abuts against the guiding portion 242 of the connecting seat 200, and the guiding elastic portion 42 bears the elastic force from the first end surface 30 to the direction of the first end surface 20, the component direction of the elastic force is opposite to the abutting force of the second bearing part 241 on the first bearing part 41, so that the first end face 20 of the connector 100 only needs to be pushed towards the second end face 30, a large area of fingerprints or scratches cannot be left on the connector 100, the connector 100 can be limited and fixed in the connecting seat 200, and the connector 100 can be detached from the connecting seat 200.

Of course, the second connecting surface 210 may not be a circular surface, but a plane surface, and correspondingly, the third end surface 220 and the fourth end surface 230 may be rectangular surfaces. Specifically, the second connecting surface 210 may be an annular inner surface or an annular outer surface.

Further, on the second connection surface 210, since the positioning portion is spaced from the guide slope 2421 in the direction parallel to the third end surface 220, the stopper surface is also spaced from the second receiving portion 241 in the direction parallel to the third end surface 220.
In the embodiment of the present invention, the connecting seat 200 may be a lamp housing for accommodating the reflector, or may be other components.
