[0002] The design of the anti-pinch function of the car door can better prevent the accidental injury caused by the passengers' hands and other body parts, or objects being caught by the car door when closing the car door, thereby improving the safety of the car. A kind of automobile conductive anti-pinch strip with patent number CN202321651839.2 is provided with an inverted U-shaped contact deformation cavity. When squeezed, the first conductive strip contacts the second conductive strip, that is, the inner and outer walls of the contact deformation cavity are in contact, and the large surface contacts the small surface, which can increase the sensitivity and accuracy of the detection, avoid the risk of detection errors, save costs, and reduce the difficulty of processing. Although this structure can improve the detection sensitivity, the wiring harness cannot be fixed, and the wiring harness can only be fixed to the anti-pinch strip by means of glue bonding, etc., which is inconvenient to install and has the risk of contamination and detachment. Once detached, it will cause the door operation and anti-pinch function to fail; and the subsequent operation of the wiring harness has the risk of damaging the wiring harness and the anti-pinch strip. One damage will cause the entire anti-pinch strip to be scrapped, causing a lot of losses. Utility Model Content
