TECHNICAL FIELD

[0001] The present application relates to the technical field of harness testing, in particular to a harness tensile testing machine. BACKGROUND

[0002] The harness is a total body of service equipment provided for a certain load source group, such as a trunk line, a switching device, a control system, etc. The basic research content of traffic theory is to study the relationship among traffic volume, call loss and harness capacity. The harness is an important basic concept in traffic theory. According to the different structures, it is divided into full utilization degree harness, partial utilization degree harness and link system. According to the different service modes, it is divided into loss system harness and waiting system harness. According to the different number of load sources of service, it is divided into infinite load source harness and finite load source harness. The standard of the harness is mainly calculated by the compression rate. The calculation of the compression rate needs to pass through a special instrument. The harness cross-section standard detector developed by Suzhou Ouka Optical Instrument Factory is the most effective detector specially used for detecting whether the compression of the harness is qualified.
