Background technique

The gearbox is an important part of the car, which is used to transmit the work of the engine to the wheels to make the car run. The gearbox, the engine and the control system need to be connected by wiring harness to realize signal transmission control. The complete wiring harness is composed of wire strips and terminals at both ends. After the production of the wiring harness is completed, it is necessary to perform a tensile test on the terminals of the wiring harness to ensure good connection strength and avoid tensile fracture or contact with external forces during assembly and use. The terminal is disconnected. The existing wire harness terminal tension test equipment uses two sets of fixtures, one set clamps the terminal through the upper and lower positions of the splint or the left and right positions, and the other set is fixed on the dynamometer to clamp the wire row by extrusion and pressing, and then press down with a wrench Keep the dynamometer away from the terminal. Due to the inaccurate control of the clamping force during the tensile test, the terminal will usually be damaged due to excessive force or the clamping force is small, and it will fall off the splint during the test. The same The wire row is also easy to fall off under the grip of the splint, resulting in test failure, and when the wrench is pressed, the spring back of the wire row will cause the dynamometer to move in the opposite direction, so it takes a long time to press the wrench to keep it still, which is not only time-consuming and labor-intensive Large, and it is difficult to grasp the strength, resulting in inaccurate measurement. In view of this, we propose a terminal tension measurement device for gearbox wiring harness.
