Specifically, the free end 332 of the locking spring presses the wire 1 extending into the cavity 400, that is, the wire 1 is pressed between the free end 332 of the locking spring and the inner side wall of the wire holder 310, and then the wire 1 is electrically connected with the contact pin 200 through the wire holder 310 made of conductive material.
When the wire 1 needs to be electrically connected with the contact pin 200, the wire 1 stretches into the cavity 400, the wire 1 cannot directly enter between the free end 332 of the wire locking elastic piece 330 and the inner side wall of the wire holder 310 due to the blocking of the free end 332 of the wire locking elastic piece 330, the operating member 320 is driven to move downwards relative to the wire holder 310, so that the operating member 320 approaches and presses the free end 332 of the wire locking elastic piece 330, the free end 332 of the wire locking elastic piece gradually approaches the fixed end 331 of the wire locking elastic piece 330, namely, the free end 332 is far away from the inner side wall of the wire holder 310 opposite to the fixed end 331, so that the gap between the free end 332 and the inner side wall of the wire holder 310 is enlarged, the wire 1 stretches into the gap between the free end 332 and the inner side wall of the wire holder 310, then the force is applied to the operating member 320 is cancelled, the free end 332 of the wire locking elastic piece 330 automatically rebounds, the free end 332 approaches the inner side wall of the wire holder 310 opposite to the fixed end 331, so that the gap between the free end 332 and the inner side wall of the wire holder 310 becomes smaller, the wire 1 is pressed between the free end 332 and the inner side wall of the wire holder 310, and the wire 1 is electrically connected with the contact pin 200 through the wire holder 310; when the wire 1 needs to be removed to release the electrical connection with the contact pin 200, the operating member 320 is driven to move downward relative to the wire holder 310, so that the free end 332 of the locking wire spring is far away from the inner side wall of the wire holder 310 opposite to the fixed end 331, and the gap between the free end 332 and the inner side wall of the wire holder 310 becomes large, so that the wire 1 is released, and then the wire 1 is pulled out from the cavity 400, so that the electrical connection between the wire 1 and the contact pin 200 is released. This application has two shell fragments of lock wire shell fragment 330 and fixed shell fragment 340 simultaneously, and fixed shell fragment 340 is connected with wire holder 310, and fixed shell fragment 340 and the inside wall joint of insulating housing 100 to realized wire holder 310, lock wire shell fragment 330 and fixed shell fragment 340 fixed relative insulating housing 100 through fixed shell fragment 340, because fixed shell fragment 340 fixed connection is on wire holder 310, fixed shell fragment 340 sets up stably, thereby has improved wire holder 310, lock wire shell fragment 330 and the reliability of fixed shell fragment 340 and plastics plug-in components assembly. In addition, since the fixed end 331 of the locking wire elastic piece 330 is also fixedly connected to the wire holder 310, the setting of the locking wire elastic piece 330 is more stable, and the pressing of the locking wire elastic piece 330 on the wire 1 is more reliable.
