Portable real vehicle wire harness installation tester

Abstract

The invention relates to a portable real vehicle wire harness installation tester. The tester comprises a wire harness probe, an adjustable resistor module, a voltage acquisition module and a main control module, the wire harness probe is used for connecting head and tail mounting points of a wire harness; the voltage acquisition module is used for acquiring a voltage signal, amplifying and filtering the acquired voltage signal and then sending the voltage signal to the main control module; the main control module is used for sampling the voltage conditioned by the voltage acquisition module to obtain the voltage between the two wire harness probes and the voltage at the two ends of the adjustable resistor module; the main control module is also used for controlling the adjustable resistor module and adjusting the resistance value of the adjustable resistor module; and the adjustable resistance module is used for adjusting different resistance values according to the analog values of the corresponding resistance values output by the main control module. The tester disclosed by the invention can be used for carrying out real vehicle testing on wire harnesses with different specifications.

Description

technical field [0001] The invention relates to the field of vehicle wire harness installation detection, in particular to a portable real vehicle wire harness installation tester. Background technique [0002] With the popularity of automobiles, there are more and more functional requirements, and the wiring harness, as one of the important signal transmission media, is becoming more and more complex, especially for hybrid vehicles. The installation quality of the wiring harness and the aging of the contact points are particularly important to the safety of the car. [0003] During the use of the wire harness, the contact resistance of the wire harness may be too large due to reasons such as rust, overheating and aging of the wire harness, and harsh vibration of the vehicle, which may cause serious safety problems such as sparking and wire harness breakage during the use of the vehicle. [0004] At present, the traditional detection methods and existing detection devices c...

Problems solved by technology

[0003] During the use of the wiring harness, the contact resistance of the wiring harness may be too large due to reasons such as rust, overheating and aging of the wiring harness, and harsh vibration of the vehicle, resulting in serious safety problems such as sparking and breakage of the wiring harness during the use of the vehicle.

[0004] At present, the traditional detection methods and existing detection devices can only detect the on-off and misconnection of the line, but cannot detect the contact resistance of the installation position of the wire harness and the resistance of the wire harness conductor itself; with the actual vehicle wire harness detection device, generally it can only detect a single Specification wiring harness, for hybrid vehicles with a wide variety of wiring harnesses, it is not universal
