Description

Technical Field

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

[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. Cable is made of one or more mutually insulated conductors and an outer insulating protective layer. It is a wire that transmits electricity or information from one place to another. It is usually a rope-like cable made of several or several groups of wires twisted together. Cable is used as a conductive carrier. When used outdoors for a long time, it is exposed to wind and rain. If it is damaged or broken due to quality problems, it is easy to cause large-scale casualties and property losses. Therefore, for safety reasons, cables need to be tested for quality before leaving the factory.

[0003] However, the existing quality inspection devices for cable production on the market generally need to replace different machines to perform various complex tests such as tensile testing and repeated bending fatigue testing when inspecting cables, which results in a long time consumption and low efficiency. For this reason, we propose a cable inspection device. Utility Model Content
