Description

Technical Field

[0001] The invention relates to the technical field of wire harness testing, in particular to a wire harness tensile testing machine. Background Art

[0002] The wiring harness is the overall service equipment for a certain group of load sources, such as relay lines, switching devices, control systems, etc. The basic research content of traffic theory is to study the relationship between traffic volume, call loss and harness capacity. The wiring harness is an important basic concept in traffic theory. According to the different structures, it is divided into full utilization harness, partial utilization harness and link system. According to the different service modes, it is divided into loss-controlled harness and waiting harness. According to the number of load sources served, it is divided into unlimited load source harness and limited load source harness. The standard of the wiring harness is mainly determined by calculating its crimping rate. The calculation of the crimping rate requires special instruments.
