By adopting the technical scheme, the forming and assembling process of the connector 31 is very simple, namely, the assembling process of the connector 31 is simplified.

In some embodiments, please refer to fig. 5 in conjunction with other figures. Fig. 5 is a partial cross-sectional view of an insulator 311 and a low voltage terminal 313 of a connector 31 according to some embodiments of the present application. The low voltage terminal 313 is detachably provided to the insulating member 311.

Thus, the low voltage terminal 313 is convenient to replace after being damaged, without replacing the whole connector 31, so that the convenience of use of the connector 31 can be improved.

In some embodiments, please continue to refer to fig. 5, in conjunction with other figures. The insulator 311 is provided with a slot 3101, and an elastic buckle 3111 is provided in the slot 3101. A portion of the low voltage terminal 313 is inserted into the slot 3101. The elastic clip 3111 elastically abuts against the low-voltage terminal 313 to abut the low-voltage terminal 313 against the inner wall of the slot 3101.

The slot 3101 refers to a slot in the insulator 311 for plugging the low voltage terminal 313. Wherein, a part of the low voltage terminal 313 is inserted into the slot 3101.

The elastic clip 3111 refers to an elastic structure of the insulating member 311 that can elastically move. Wherein the elastic buckle 3111 elastically abuts against the low-voltage terminal 313 to abut the low-voltage terminal 313 against the inner wall of the slot 3101. Specifically, the elastic clip 3111 elastically abuts against one side of the low-voltage terminal 313 to provide an elastic force to the low-voltage terminal 313, so that the other side of the low-voltage terminal 313 away from the elastic clip 3111 abuts against the inner wall of the slot 3101. In this way, opposite sides of the low voltage terminal 313 are respectively abutted against the elastic snap 3111 and the inner wall of the slot 3101, so that a portion of the low voltage terminal 313 is detachably fixed within the slot 3101.

The low voltage terminal 313 is elastically abutted against the low voltage terminal 313 by the elastic clip 3111 to abut the low voltage terminal 313 against the inner wall of the slot 3101, so that a portion of the low voltage terminal 313 is detachably fitted to the slot 3101. In this way, by providing an external force to the elastic buckle 3111, the elastic buckle 3111 can remove the elastic force to the low voltage terminal 313, so as to facilitate the detachment of the low voltage terminal 313 from the socket 3101, and further facilitate the replacement of the low voltage terminal 313 on the insulator 311.

In some embodiments, referring to fig. 5, the slot 3101 may be configured as a through slot penetrating the insulating member 311 along the first direction Z. One part of the low-voltage terminal 313 is inserted into the slot 3101 along the first direction Z, and the other part of the low-voltage terminal 313 extends out of one end of the slot 3101 along the first direction Z. Based on this, the structural member can be inserted from the other end of the slot 3101 in the first direction Z, and by pulling the elastic buckle 3111 through the structural member, the elastic force to the low-voltage terminal 313 can be removed by the elastic buckle 3111, thereby facilitating the removal and replacement of the low-voltage terminal 313.

In some embodiments, referring to fig. 5, the elastic clasp 3111 may be provided with a slope 3103, the slope 3103 being inclined compared to the first direction Z. In this way, during the entry of the structural member into the socket 3101 from the other end of the socket 3101 in the first direction Z, the structural member may provide a force to the inclined surface 3103 so that the elastic catch 3111 removes the elastic force to the low voltage terminal 313.

It should be noted that the first direction Z is parallel to the Z axis and parallel to the plugging direction in which the low voltage terminal 313 is plugged into the socket 3101.
