Wire harness detection device for voltage acquisition wire

Abstract

The invention provides a wire harness detection device for a voltage acquisition wire. The device includes a wire harness detector and an acquisition port conversion module, which are mutually connected. The acquisition port conversion module is connected with one end of the wire harness of the voltage acquisition wire so as to acquire a voltage signal of a battery pack which is connected with the other end of the wire harness of the voltage acquisition wire. The wire harness detector includes a detection board with N channels, a battery module, an N-pin plug-in and a display module. One end of the N-pin plug-in is connected with the acquisition port conversion module and the other end is connected with the voltage detection board with N channels. The device adopts separate voltage acquisition and detects the value of a battery-pack voltage which passes the wire harness of the voltage acquisition wire so as to judge whether the wire harness of the voltage acquisition wire is in an open circuit or reverse connection and the detection result is displayed on a handset or a liquid-crystal display screen; universality of the wire harness detector is realized through the acquisition port conversion module and compatibility of a plurality of kinds of plug-ins is realized; and the device is high in visualization and interactivity and directly observable in detection result so that the detection procedure is simplified and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of wire harness detection, in particular to a wire harness detection device for a voltage acquisition wire of an automobile. Background technique [0002] The automotive wiring harness plays a pivotal role in the vehicle system. The wiring harness is connected between the electrical appliances and between the electrical appliances and the power supply, which has a great impact on the performance and safety of the vehicle. The voltage acquisition line has a large number of wiring harnesses. During the battery assembly process, the voltage acquisition line is prone to disconnection or reverse connection. If the voltage acquisition line is connected to the battery management system at this time, it will cause the electrical equipment to lose control and may be caused by overvoltage. Burning out the battery management system, causing explosions and fires and other safety accidents, so the detection of wire harnesses is e...

[0002]The automotive wiring harness plays a pivotal role in the vehicle system. The wiring harness is connected between the electrical appliances and between the electrical appliances and the power supply, which has a great impact on the performance and safety of the vehicle. Large, but in the battery management system, the voltage acquisition line connected to multiple batteries has a large number of wiring harnesses, and it is easy to disconnect or reverse the connection of the voltage acquisition line during the battery assembly process. If the voltage acquisition line is connected to the battery at this time management system, it will lead to loss of control of electrical equipment and may cause safety accidents such as overvoltage burnout of the battery management system, explosion and fire, so the detection of wiring harnesses is extremely important, but the current detection of wiring harnesses is not intelligent enough, and the status of detected wiring harnesses is displayed It is not intuitive enough, resulting in low detection accuracy, and a single wire harness connector will have multiple different voltage acquisition chips connected to it. At the same time, different voltage acquisition port interfaces are composed of different connectors, and there are many types. When it is necessary to replace the connector, the process increases, the production process is complicated, and the production efficiency is low
