Description

Technical Field

[0001] The utility model relates to the technical field of automobile wiring harness auxiliary devices, in particular to a device used for auxiliary testing of the welding pulling force of a sliding switch on an automobile wiring harness. Background Art

[0002] In the process of automobile wiring harness processing, according to the processing technology and operation flow of automobile wiring harness products, employees need to use a tensile machine to test the welding pull-out force of the welded harness switch according to the requirements of the drawings before and during each batch of processing. For this type of sliding switch, customers require that the pull-out force should be tested along the horizontal direction of the wire. First, the switch is fixed horizontally on the tensile machine, along the direction of the wire, and the switch is kept horizontal for testing. The test piece fixing module of the standard tensile machine purchased outsourced is in the form of a disc, which is mostly suitable for the test of the terminal crimping tensile resistance. The test switch cannot be well matched in the fixing module of the tensile machine. Therefore, when the existing wire harness with switch is tested for welding pull-out force, employees need to manually hold the switch, keep the switch horizontal, and then pull it along the axial direction of the wire. This state will cause work fatigue for employees for a long time, and because the switch is manually held, it cannot be fully guaranteed to be in a horizontal state, which has the risk of unstable and inaccurate tensile test, resulting in product defects and unrecognizable effects. This method has the defects of laborious employees, high production time cost, low efficiency, and high quality risk. Utility Model Content
