Description

It drives a vehicle special tensile wear-resistant flexibility flat cable

Technical field

The utility model is related to electronic wire technical fields, and in particular to special tensile wear-resistant flexibility flat cable of driving a vehicle.

Background technology

Driving is a kind of mechanism of intermitten, is widely used in factory, building site, goods yard as a kind of crane hoisting equipment The indoor and outdoors such as harbour place.Current driving cable, surface is easy to wear in moving process of driving a vehicle, and Long-term bend causes Conductive cable cores easy fracture easily causes to break.And general conventional round cable is easily rolled in mobile alternating bending and is made It radially distorts, frequently multiple radial distorted can influence the internal structure of cable, shorten the working life.

Utility model content

The purpose of this utility model is that disclosing the special tensile wear-resistant flexibility flat cable of driving, solves existing driving and use The problem of cable is easy to wear, easy fracture.

In order to achieve the above objectives, the utility model adopts the following technical solution：

Drive a vehicle special tensile wear-resistant flexibility flat cable, include from the inside to the outside several conductor wire cores, be wrapped in it is described several Band outside root conductor wire core, the first silicone resin layer, aluminium strip lapped shielding layer and TPE oversheaths set on band outer surface Layer (TPE：Thermoplastic Elastomer, thermoplastic elastomer (TPE))；Several conductor wire cores are arranged side by side.

Further, the section of the special tensile wear-resistant flexibility flat cable of driving is in the tetragonal structure equipped with rounded corner.

Further, the gap between several conductor wire cores and the band is filled with the rubber that blocks water.

Further, the conductor wire core includes the conductor being made by twisting by several tinned copper wires from the inside to the outside, is coated on The polyimide coating of conductor outside surfaces, anti-corona coating and the second silicone resin layer.

Further, the aluminium strip lapped shielding layer is made of polyethylene and aluminium wire netting, and polyethylene is in right-angled intersection side Formula is wrapped in outside the band, is tightened by aluminium wire netting winding in the outside of polyethylene.

Compared with prior art, the beneficial effects of the utility model：

The utility model using section in flat structure, using the first silicone resin layer, aluminium strip lapped shielding layer, The structure of TPE external sheath layers and the rubber that blocks water, with warp resistance, wearability is good, softness is good, tensile property is strong, antifatigue Property, good weatherability, water resistance it is good, excellent electrical properties, service life length etc. a series of excellent specific properties.Using the first organosilicon The structure of resin layer and the second silicone resin layer, have excellent thermo oxidative stability, electrical insulation capability, weatherability, waterproof, The characteristics such as salt spray proof, mould proof, biocompatibility.Conductor is made by twisting using tinned copper wire, and soft steel wire conductor structure makes With not only ensure that the flexibility of cable, but also greatly strengthen the tensile property of cable；Using aluminium strip lapped shielding layer, further really Having protected cable has preferable flexibility, is readily bent.
