Description

Technical Field

[0001] The utility model relates to the technical field of automobile wiring harness detection, in particular to a combined wiring harness detection device for new energy vehicles. Background Art

[0002] The automotive wiring harness is composed of a wiring harness and a terminal. The wiring harness must be pressed on the terminal to have a certain clamping force requirement, that is, the wiring harness and the terminal will not be pulled off under a certain tensile force after being pressed. If the requirement is not met, it means that the tensile strength of the wiring harness and the terminal is unqualified. Such automotive wiring harnesses are prone to the risk of disconnection under the action of external forces, resulting in electrical appliances not working properly. Therefore, the tensile force detection of the wiring harness and the terminal plays a key role in the production process of automotive wiring harnesses;

[0003] The traditional combined wiring harness detection device for new energy vehicles has some disadvantages. Generally, the two ends of the wiring harness need to be fixed. Generally, two clamps threaded on the screw are used to fix the wiring harness, so as to perform tensile detection on the wiring harness. At the same time, due to the influence of the length of the wiring harness, it is not convenient to limit the middle position of the wiring harness, which causes the wiring harness to tilt, thus affecting the tensile detection of the wiring harness.
