Description

Technical field:

[0001] The utility model belongs to the technical field of wire harness terminal production, and particularly relates to a wire harness terminal tension tooling. Background technology:

[0002] Wire harness terminals are electrical components on electric vehicles. Ultrasonic welding is often used to weld the wire harness and the terminal together during the production process of the wire harness terminals. In order to ensure the quality of the wire harness terminals after welding, a tensile testing machine is required to test the strength of the welding part of the wire harness terminals.

[0003] In traditional tensile testing, the tensile machine clamps the wire harness and one end of the terminal respectively, and then pulls the wire harness and the terminal apart at a uniform speed to obtain the tensile force required to pull the wire harness and the terminal apart, and judges whether the strength of the wire harness terminal welding point is qualified based on the required tensile force. However, in actual testing, due to the low structural strength of the wire harness terminal itself after welding, when the tensile machine is working, the wire harness terminal welding point is often not pulled apart, and the wire harness terminal has been deformed and broken, resulting in inaccurate tensile force value testing, which affects the wire harness terminal tensile test.
