Description

Technical Field

[0002] Motor vehicle wiring harness is one of the most critical parts inside a motor vehicle, and its quality, safety and reliability are crucial to the quality of the motor vehicle. The function of the wiring harness connector is to connect different wires together, so that current can flow and the entire circuit can achieve the predetermined function. During the production process, detection means are needed to detect whether the wiring harness is qualified, that is, whether the signal or instruction can be fed back in time. The qualification of the wiring harness is usually determined by testing the wiring harness connector. Therefore, when the motor vehicle wiring harness connector is tested for electrical appliances, the connector, as the core component of the wiring harness, has a great impact on the overall performance of the wiring harness.

[0003] The wiring harness connector generally includes a first connector and a second connector that match each other. When the wiring harness is detected, the connection end of the detection device has a second connector that is plugged and matched with the first connector at the end of the wiring harness. In the prior art, the first connector and the second connector are connected by snapping, one end of the second connector has a slot, and one end of the first connector has a tenon. When in use, after the first connector is inserted into the second connector, the tenon is fixed in the slot. Another connection method is threaded connection. After the first connector is inserted into the second connector, the threaded sleeve on the outside of the first connector is threadedly connected to the second connector by rotating the threaded sleeve, or the first connector has a screw, and the first connector and the second connector are connected by rotating the screw.

[0042] In order to facilitate use and reduce costs, the first plug-in portion is configured as a plug and the second plug-in portion is configured as a socket.

[0043] When in use, a person presses the force-bearing end of the force transmission component with his hand. When the force-bearing end of the force transmission component is subjected to pressure, the output end of the force transmission component drives the second rotating end to rotate, and the second rotating end drives the first rotating end to rotate, so that the second locking tooth 42 of the first rotating end is disengaged from the first locking tooth 41, and then the plug is unplugged to achieve the separation of the plug and the socket.

[0044] During docking, the person presses the force-bearing end of the force-transmitting component with the hand, and after the first plug-in part and the second plug-in part are plugged in, the person releases the force-bearing end of the force-transmitting component with the hand.
