Description

Technical Field

[0001] The utility model relates to the technical field of electric wires and cables, in particular to an anti-entanglement electric wire and cable. Background Art

[0002] Wires and cables refer to materials used for power, electrical and related transmission purposes. There is no strict boundary between "wires" and "cables". Usually, products with a small number of cores, small product diameters and simple structures are called wires, those without insulation are called bare wires, and others are called cables; conductors with larger cross-sectional areas (greater than 6 square millimeters) are called large cables, and those with smaller cross-sectional areas (less than or equal to 6 square millimeters) are called small wires, also known as cloth wires;

[0003] Since the cable is long when it is laid, it may get tangled and knotted during the laying process. The cable laid in front of the knot needs to be re-laid. Sometimes the knot is tight and inconvenient to untie, so it can only be cut at the knot, which is inconvenient to use. Utility Model Content

[0006] In order to improve the overall bending resistance of the cable, as a preferred anti-entanglement wire and cable of the utility model, the installation groove is a threaded structure wrapped around the outer wall of the installation base.

[0007] In order to improve the overall bending and torsion resistance of the cable, as a preferred anti-entanglement wire and cable of the utility model, the anti-bending ribs are made of TPU material.

[0008] In order to improve the waterproof and fireproof effect of the cable, as a preferred anti-entanglement wire and cable of the utility model, the fireproof and waterproof layer is a composite material of polyethylene foam and polyphenylene sulfide.

[0009] In order to improve the high temperature resistance of the cable, as a preferred anti-entanglement wire and cable of the utility model, the inner sheath is made of silicone rubber.

[0010] In order to improve the compression resistance of the cable, as a preferred anti-entanglement wire and cable of the utility model, the installation base layer is butyl rubber.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The fireproof and waterproof layer is a composite material of polyethylene foam and polyphenylene sulfide. The polyethylene foam has multiple independent bubbles inside, has good waterproof and moisture-proof properties, effectively prevents the entry of moisture, and improves the moisture-proof effect of the cable. The polyphenylene sulfide material has better flame retardancy, which improves the fireproof and waterproof properties of the cable. The inner sheath is made of silicone rubber and has strong high temperature resistance, which improves the high temperature resistance of the cable. At the same time, it is convenient for the internal fixed connection of the inner sheath with multiple evenly distributed anti-bending ribs. The anti-bending ribs are made of TPU material, which has the characteristics of high tension, high tensile force, strong toughness and aging resistance. At the same time, they have strong anti-bending and anti-torsion capabilities. When the wires and cables are bent, they can be quickly reset, thereby avoiding the entanglement of the wires and cables. The installation base is butyl rubber, which is convenient for opening an installation groove on the outer wall. A spring wire is embedded in the installation groove. By setting the spring wire, the entire wire and cable is further made more elastic, the anti-bending and anti-torsion capabilities are improved, and entanglement is effectively prevented.
