Description

Technical Field

[0001] The utility model relates to a visual detection device for insulating layers of electric wires and cables. Background Art

[0002] Wires and cables are basic products used to transmit electrical (magnetic) energy, transfer information, realize electromagnetic energy conversion and constitute automatic control circuits. There is no strict distinction between wires and cables. Wires and cables in a broad sense can also be called cables. Products with simple structures, no outer sheaths and small outer diameters are usually called wires, and products with complex structures, solid sealed outer sheaths and large outer diameters are called cables. The main structure of wires is "conductor + insulation", and the main structure of cables is "conductor + insulation + sheath"; conductors are generally made of copper, aluminum or their alloys, and insulation and sheaths are generally made of rubber, polyethylene, polyvinyl chloride and other materials.

[0003] According to the different insulating materials of insulation and sheath, wires and cables can be divided into rubber-sheathed cables and plastic cables. Rubber-sheathed cables, also known as rubber cables, are a kind of soft and movable cable with multiple strands of thin copper wire as conductors, rubber insulation and rubber sheaths. They have good bending properties and are particularly suitable for mobile power consumption and power supply devices that need to be bent frequently and are often used in harsh environments such as radiation sites. Plastic cables mainly include PVC cables, fluoroplastic cables, nylon cables, polyethylene cables, etc. Their manufacturing process is simple and their prices are lower than those of rubber-sheathed cables. Among them, PVC cables are wires and cables with polyvinyl chloride (PVC) as insulating materials. This type of insulating material has become one of the commonly used insulating materials for wires and cables due to its low price, good mechanical energy, simple manufacturing process, and light specific gravity; fluoroplastic cables are wires and cables with fluoroplastics as insulating materials. They have the characteristics of high temperature resistance, good flame retardancy, and aging resistance. They are mainly used for high-frequency signal transmission with high temperature resistance.

[0004] With the increase in the number of wires and cables, higher and higher requirements are put forward for the performance and driving safety of wires and cables. The mandatory standard GB 5023 has strict requirements on insulation thickness. Unqualified insulation makes the insulation unable to isolate the charged body from other parts, and the sheath reduces its ability to resist various types of external corrosion, which makes it easy for the insulation to be exposed to the external environment and reduce its dielectric properties. At present, the detection methods and devices used by inspection agencies are labor-intensive, inefficient, and have a high rate of human error. Utility Model Content
