Simple wire harness conduction detector

The utility model provides a simple wire harness conduction detector, belonging to the field of detection control. The detector includes a power supply module, a single-chip microcomputer, an audible and visual alarm module, a wire harness interface module, a button input module, and a liquid crystal display module, the modules are connected with the single-chip microcomputer, the interfaces of the two terminals of a wire harness are included in the wire harness interface module and are connected with the corresponding pins of the single-chip microcomputer via the wire harness interface module, the button input module inputs the lead number of the wire harness terminals to be measured, the single-chip microcomputer sets the pins, which are corresponding to the leads in number, in the interfaces of the two terminals of the wire harness into high level and low level respectively, the lead number and the pins at the high level and the low level are displayed on the liquid crystal display module, the two terminals of the wire harness are connected to the corresponding pins via the wire harness interface module, the single-chip microcomputer detects whether the corresponding pins switch to the low level at the same time or not, if yes, the corresponding leads in the two terminals of the wire harness are conducted, if no, the corresponding leads in the two terminals of the wire harness are disconnected, and then the audible and visual alarm module works, and the positions of the corresponding leads in the two terminals of the wire harness are displayed on the liquid crystal display module.
