Waterproof soft cable

Abstract

The invention discloses a waterproof soft cable which comprises a cable core. The cable core is formed by twisting three insulating wire cores. A stuffing layer formed by stuffing is arranged in a gap in the cable core. The outmost layer of the cable is coated with a polyurethane elastomer outer protective layer in an extruding mode. Each insulating wire core is composed of a copper conductor and insulating layers sequentially wound on outside the conductor. Compared with an existing waterproof cable, fundamental difference is that an outer protective sleeve is made of a different material, and therefore the waterproof soft cable has the functions of an ordinary waterproof cable, can work normally under the extremely cold condition of low temperature of -40 DEG C and is pressure resistant, anti-abrasion, anti-corrosion and capable of maintaining soft performance.

Description

[0001] technical field

[0002] The invention relates to the field of wires and cables, in particular to a low-temperature-resistant, pressure-resistant, corrosion-resistant, waterproof flexible cable. Background technique

[0003] Since the beginning of the 21st century, with the continuous development of electric power industry, data communication, automobile industry and transportation industry, the demand and requirements for wire and cable have also increased rapidly, which makes the future cable industry have huge development potential.

[0004] At present, the existing cables are mainly composed of inner conductors, insulating layers, outer conductors and sheaths; due to their use requirements, they are more exposed to the outdoors, and outdoor construction often encounters such as low-temperature cold currents, acid-base corrosion, oil pollution, crowding, etc. When the sheath is damaged or the joints at both ends of the cable are not tightly sealed, moisture and rai...

Examples

Embodiment Construction

[0017] like figure 1 As shown, a waterproof flexible cable according to the present invention includes a cable core, which is characterized in that the cable core is formed by twisting three insulated wire cores; the inner space of the cable core is provided with a filling layer 3 made of filling, The outermost layer of the cable is extruded with a polyurethane elastomer outer sheath 4; the insulated wire core is composed of a copper conductor 1 and an outer insulating layer 2 wrapped around the conductor 1 in turn.

[0018] The present invention provides an idea and implementation method of a waterproof flexible cable. There are many specific application methods. The above description is only a preferred embodiment of the present invention. Under the premise of the principle of the invention, some improvements can also be made, and these improvements should also be regarded as the protection scope of the present invention.
