Embodiment Construction

[0015] The technical solution of the present invention is to be used for testing the cable with multiple core wires, such as figure 1 As shown, in the first embodiment of the cable testing device of the present invention, it includes a first test joint 21 and a second test joint 22 respectively connected to two ends of the cable 1, the first test joint 21 and the second test joint 22 After connecting the two ends of the cable 1, the core wires of the cable 1 will be connected in series to form a test circuit, and then the test circuit will be formed after connecting the series test circuit with the positive and negative interfaces of the test instrument. Among them, The multimeter will be set to the resistance measurement mode. Therefore, if the multimeter has a certain reading, it can be judged that the test line is connected at this time, that is, there is no disconnection of each core wire of cable 1. In specific design, the test instrument can be a multimeter or a resistan...

Abstract

The invention relates to a cable testing device, which is used for testing a cable with a plurality of cores and comprises a first testing connector and a second testing connector which are respectively connected at two ends of the cable so as to connect a plurality of cores of the cable in series into a testing circuit, thus being connected with a positive interface and a negative interface of amultimeter, thereby forming a testing loop. The technical proposal adopts passive design, i.e. an external power supply is not required, the multimeter is directly used for detection, the testing efficiency is high and the testing time is second-magnitude; the cable testing device can prevent judging a failure cable as a good cable under multi-failure condition (i.e. wire breakage and continuous pin occur simultaneously); therefore, the testing items are complete and any problems during the processing of the cable can be found.

Description

technical field [0001] The present invention relates to testing devices, and more particularly, to a cable testing device. Background technique [0002] At present, the cable test needs a special circuit, which is complicated to implement and the test efficiency is relatively low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cable testing device for the above-mentioned cable testing in the prior art, which requires a special circuit, is relatively complicated to implement, and has relatively low testing efficiency. [0004] The technical solution adopted by the present invention to solve the technical problem is: to construct a cable testing device for testing a cable with multiple core wires, which includes a first test joint and a second test joint respectively connected to the two ends of the cable , used to connect multiple core wires of the cable in series to form a test line, so as to be connected to ...
