Test box special for pre-assembled quick connectors and cables

Abstract

The invention discloses a test box special for pre-assembled quick connectors and cables. The test box comprises a shell which comprises a box body and a box cover, a power source joint, a cable socket, an indicating lamp, a cable triphase joint and a conversion switch are arranged on the box cover, the power source joint is coupled with an outside power source, the cable socket and the cable triphase joint are both used for inserting connection with a to-be-tested cable, the power source joint comprises a null line joint coupled with an outside null line and a live line joint coupled with an outside live line, and the indicating lamp, the cable triphase joint, the cable socket and the conversion switch are mutually connected serially between the null line joint and the live line joint. By arranging the indicating lamp, the cable triphase joint, the cable socket and the conversion switch on the box cover, parts can be provided for cable testing effectively; compared with the prior art of adopting a mode of testing through a multimeter, the test box has the advantage of being simpler and more accurate.

Description

technical field [0001] The present invention relates to a test equipment, more specifically to a pre-installed quick connector and a special test box for cables. Background technique [0002] Cable testing is a very important step in the process of cable production and use. Through cable testing, you can effectively know the withstand voltage of the cable, whether the internal circuit of the cable is in a conductive state, and the cable plug connector. Whether the self-shorting structure can work normally. [0003] In the prior art, when the cable is tested, it is generally selected to connect the cable to the power supply, and then use a multimeter to detect the current flowing through the cable, so as to achieve the effect of detecting the cable power supply. There are many cores inside, so when detecting the on-off condition of each channel, it is necessary to contact the multimeter with each core. Due to the limited volume of a cable plug, the distance between each core...

[0003] In the prior art, when the cable is tested, it is generally selected to connect the cable to the power supply, and then use a multimeter to detect the current flowing through the cable, so as to achieve the effect of detecting the cable power supply. There are many cores inside, so when detecting the on-off condition of each channel, it is necessary to contact the multimeter with each core. Due to the limited volume of a cable plug, the distance between each core is not very good. Large, so it is easy to appear that the multimeter encounters other cores during the detection process, resulting in inaccurate detection. At the same time, it is very inconvenient to operate during the detection process.
