Thus, when the upper housing 12 is covered on the lower housing 11, the first conductive terminal 651 is electrically connected to the third conductive terminal 641, and the second conductive terminal 652 is electrically connected to the fourth conductive terminal 642, so that the first conductive terminal 651 transmits electricity to the second conductive terminal 652 through the third conductive terminal 641 and the fourth conductive terminal 642 to output power to the outside due to the electrically conductive connection between the third conductive terminal 641 and the fourth conductive terminal 642; and because the upper housing 12 is detachably fixed on the lower housing 11 through the fastening mechanism, the upper housing 12 is separated from the lower housing 11, and the electrical connection between the first conductive terminal 651 and the second conductive terminal 652 can be disconnected, i.e., the electrical connection or disconnection between the first conductive terminal 651 and the second conductive terminal 652 is very convenient.

Wherein in one embodiment the over-current protector 5 has a predetermined current threshold.

Further, referring to fig. 1 to 10, as an embodiment of the connector provided by the present invention, the overcurrent protector 5 is a fuse. Thus, the fuse opens when the current reaches the current threshold.

Specifically, in one embodiment, the buffer 81 is in contact with a central region of the overcurrent protector 5. Thus, when the buffer member 81 applies an external force to the overcurrent protector 5, the buffer member 81 can more effectively support the overcurrent protector 5 and maintain the stability of the overcurrent protector 5.

Specifically, in one embodiment, the positioning plate 82 is spaced apart from the upper housing 12, and/or the positioning plate 82 is spaced apart from the overcurrent protector 5.

Further, referring to fig. 1 to 10, as an embodiment of the connector provided by the present invention, an edge of an inlet of the slide groove 73 has a guide surface 731 for guiding the rod 74 to slide into the slide groove 73. Thus, the entrance of the slide groove 73 has a guide surface 731, which facilitates the rod body 74 to slide along the guide surface 731 from the entrance into the slide groove 73.

Further, referring to fig. 1 to 10, as an embodiment of the connector provided by the present invention, a limiting member 75 is disposed on the lower housing 11 and located on a rotation path of the rod 74 rotating around the pivot 72. Thus, the limiting member 75 can limit the rod 74 during the rotation of the rod 74.

Thus, the lower housing 11 is provided with the first and second

conductive terminals

651 and 652, and the upper housing 12 is provided with the third and fourth

conductive terminals

641 and 642; the third conductive terminal 641 is conductively connected to the fourth conductive terminal 642, and the external cable can be connected to the first conductive terminal 651 through the wire hole 113 on the lower housing 11; when the upper housing 12 is folded on the lower cover, the third conductive terminals 641 are inserted into the first conductive terminals 651, the fourth conductive terminals 642 are inserted into the second conductive terminals 652, and the first conductive terminals 651 form a current loop through the third conductive terminals 641, the fourth conductive terminals 642 and the second conductive terminals 652; when the upper housing 12 is separated from the lower cover, the first conductive terminal 651 is disconnected from the third conductive terminal 641, and the second conductive terminal 652 is disconnected from the fourth conductive terminal 642; that is, the closing/opening of the current path can be very conveniently performed by the closing/separating of the upper case 12 and the lower case 11.

Specifically, in one embodiment, the mounting hole 821 is opened in a central region of the positioning plate 82. In this way, when an external force is applied to the cushion member 81 positioned in the mounting hole 821 and the positioning plate 82, the shape of the positioning plate 82 can be kept stable. Specifically, in one embodiment, the central region of the positioning plate 82 is overhead. In this manner, the positioning plate 82 is easily released from vibration during the vibration.

Specifically, in one embodiment, the third conductive terminal 641 and the fourth conductive terminal 642 are L-shaped. Thus, the third conductive terminal 641 and the fourth conductive terminal 642 are anti-bent.

Specifically, in one embodiment, the third conductive terminal 641 extends and bends toward a direction away from the housing, and the fourth conductive terminal 642 extends and bends toward a direction away from the housing.
