[0002] The automotive wiring harness is mainly used to connect the battery, distribution box, actuator, controller, sensor and other components of the vehicle, provide power and signal transmission for the electrical and electronic components of the vehicle, and provide basic connection for the control circuit to realize all electrical functions. With the rapid development of automotive electronics and informatization, the extensive use of electronic equipment in the car has made the electrical wiring in the car longer and more complicated. As the relay station of the wiring harness in the automotive circuit, the connector plays an important role in the signal transmission of the whole vehicle. The existing connector generally includes a base, a connecting column and a conical connector. During assembly, the operator uses external force to squeeze and deform the conical connector and insert it into the sheet metal assembly hole to achieve clamping and fixing. Since the conical connector is conical in shape, the buckle is easily interfered by the surrounding components in the sheet metal assembly hole and easily rotates, making it impossible to completely fix the buckle. The rotation of the connector may cause the connector or the transmission harness to interfere with the surrounding components, increase the risk of wear of the wire transmission harness, and even cause the circuit of the whole vehicle to be broken, thereby affecting driving safety.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5, including a door sheet metal inner panel 1, a special-shaped mounting hole 11 is opened on the door sheet metal inner panel 1, the special-shaped mounting hole 11 includes an arc-shaped portion 111 and a square portion 112, a connector 2 is installed on the special-shaped mounting hole 11, the connector 2 includes a shell 21, a plug connector 23 is fixedly connected to the side of the shell 21, the plug connector 23 includes a plug portion 231 and a limiting portion 232, a wire insertion portion 22 is provided at one end of the shell 21, and a wiring portion 24 is provided at the other end, and a transmission line 25 is connected to the wiring portion 24. During use, the operator inserts the connector 2 into the special-shaped mounting hole 11. During insertion, the connector 23 enters the arc portion 111 of the special-shaped mounting hole 11, and the limiting portion 232 enters the square portion 112, thus completing the connection. The connector 2 is restricted by the square portion 112 through the limiting portion 232 and cannot rotate, thereby ensuring that the connector 2 will not rotate due to external interference after being connected to the door sheet metal inner panel 1, maintaining a stable connection between the connector 2 and the door sheet metal inner panel 1, avoiding the connector 2 from rotating and causing the connector 2 or the transmission line 25 to interfere with surrounding components, reducing the risk of wear of the transmission line 25, preventing the vehicle circuit from being broken, and improving driving safety.

[0020] In some embodiments, a buffer portion 233 is provided on the plug connector 23 at the side of the plug portion 231. When the operator inserts the connector 2 into the special-shaped mounting hole 11 of the door sheet metal inner panel 1, the buffer portion 233 can play a buffering role, so that the door sheet metal inner panel 1 will not be hit by the connector 2, thereby protecting the door sheet metal inner panel 1 from damage.

[0021] In some embodiments, the buffer portion 233 is in an open shape and covers the plug portion 231. The buffer portion 233 is in an open shape and covers the plug portion 231. It can not only open toward both sides of the plug portion 231 when the connector 2 is inserted into the special-shaped mounting hole 11, play a buffering role, and allow the plug portion 231 to be smoothly inserted into the special-shaped mounting hole 11, but also protect the plug portion 231 from external interference after the connector 2 is inserted into the special-shaped mounting hole 11, ensuring a stable connection.

[0022] In some embodiments, the buffer portion 233 is provided with a chamfer on one side close to the door sheet metal inner panel 1.
