Description

Technical Field

[0001] The utility model belongs to the technical field of wire harness detection, and particularly relates to a wire harness connector detection jig. Background Art

[0002] A wiring harness, also known as a wire harness or wire bundle, refers to a wire assembly in which multiple wires or cables are assembled together and fixed as a whole after being wound with materials such as plastic or rubber. A wiring harness can connect multiple devices and is an indispensable part of modern industry and transportation. A wiring harness consists of a wiring harness and a connector. According to national standards, the wiring harness and the connector should not be pulled off under a certain tensile force after being tightened. If the requirements are not met, it means that the tensile strength of the wiring harness and the connector is unqualified. Such a wiring harness is prone to the risk of decoupling under the action of external force, so a detection fixture is needed to perform tensile testing on the wiring harness connector.

[0003] In comparison, a Chinese patent with authorization announcement number CN220251538U discloses a wiring harness connector detection fixture, including a base plate; the base plate: a mounting plate is arranged on the left side of its upper end, and a vertical plate is arranged symmetrically on the upper end of the mounting plate, and electric push rods are arranged in the mounting holes inside the vertical plates, and the telescopic ends of the electric push rods located on the same side are fixedly connected to a wiring harness clamp, and the relatively inner ends of the wiring harness clamps are arranged with anti-slip teeth, and sliding grooves are respectively opened on the middle side of the upper end of the base plate, and a movable plate is slidably connected between the two sliding grooves, and a connector clamp is symmetrically slidably connected in the sliding groove inside the movable plate, and a bracket is arranged on the right side of the upper end of the base plate, and a roller is rotatably connected between the upper end of the bracket and the base plate through a bearing, and a pull rope is wrapped around the outer arc surface of the roller.

[0004] The above patent can only detect one connector of the wiring harness at a time, and connectors are installed at both ends of the wiring harness, so the connectors at both ends of the wiring harness need to be detected twice, and the detection speed is slow. Therefore, a new device needs to be designed. Utility Model Content
