Detection mechanism of circuit breaking and short circuit of wires and cables

Abstract

The invention relates to a detection mechanism of circuit breaking and short circuit of wires and cables, belonging to the technical field of detection devices of the wires and the cables and comprising a detection instrument, a wire holder fixing plate with a separating cavity, a group of wire holders, first signal connecting wires, second signal connecting wires and a circuit breaker, wherein the wire holder fixing plate is provided with a group of signal wire holes which are communicated with the separating cavity; a digital sequence number is respectively labeled on the wire holder fixing plate and positions corresponding to the group of signal wire holes; the group of wire holders are fixed on the wire holder fixing plate and correspond to the signal wire holes; the number of the first signal connecting wires is equal to that of the wire holders; one end of each first signal connecting wire is electrically connected with a wiring port of the detection instrument for testing the short circuit, and the other end is introduced into the separating cavity and is electrically connected with the wire holders after penetrating through the signal wire holes; and one end of each second signal connecting wire is connected with a wiring port of the detection instrument for testing the circuit breaking, and the other end is electrically connected with the circuit breaker. The detection mechanism has the advantages of high detection speed and no detection omission phenomenon, and effectively reduces the labor intensity of detection workers.

Description

technical field [0001] The invention belongs to the technical field of cable detection devices, and in particular relates to a wire and cable break and short circuit detection mechanism. Background technique [0002] As known in the industry, in order to ensure the quality of wires and cables, 100% open circuit and short circuit detection must be performed on the wires and cables before leaving the factory, that is, it is not allowed to detect open and short circuits by random inspection. At present, the detection of open circuit and short circuit of wires and cables usually requires two workers to work together. First, the insulation sheath at the end of the core wire is peeled off, and then the colors are compared with each other. Through the display and / or alarm of the instrument, it is judged whether the wire is short / broken circuit. Since there are usually dozens or even hundreds or hundreds of wires in a cable, it takes a long time to complete the detection of whethe...

Problems solved by technology

For example, it takes two people about 90 minutes to detect short circuit and open circuit on a cable with 50 cores to 100 cores, and it is not enough to avoid missed detection.
