Description

Technical Field

[0001] The utility model relates to the technical field of communication cables, in particular to a communication cable conductivity testing device. Background Art

[0002] Communication cables are widely used. Whether communication is normal is closely related to the components of the communication link, such as the communication transmitter, the receiver, and the communication cable. Among them, communication cables are often damaged in conductivity, resulting in communication abnormalities. When communication problems occur, checking the conductivity of the communication cable is often the first inspection direction. Among the commonly used communication methods, RS485, RS232, and RS422 serial ports are widely used. When checking such multi-pin serial port line communications, the common method is for two working members to use the same multimeter resistance range probe, with pins corresponding to pins, to check the resistance between the pins at both ends of the cable. This method first requires two members to work at the same time, and there are problems such as unstable contact between the multimeter wiring and the pins, the serial port connector is small and difficult to contact, and the probe accidentally touches other pins, which often leads to troublesome conductivity measurements and inaccurate measurement results.
