AI Technical Summary

Benefits of technology

【0008】 本発明によれば、PTFEを絶縁被覆の材料として、平行電線を得ることができる。PTFEは、耐熱性、耐薬品性に優れ不燃材料であることから、平行電線も同様の優れた特性を得ることができる。また、この平行電線は、電線同士が確実に連結されており、割れ等を生じることはない。また、導体と絶縁被覆が密接していれば、導体が引き抜けてしまうことはなく、導体と絶縁被覆の間に水等が容易に浸入してしまうことも防止できる。

Abstract

To provide a parallel electric wire of PTFE that has excellent heat resistance and chemical resistance and is an incombustible material.SOLUTION: A parallel electric wire 10 in which a plurality of electric wires 5,5' made of conductors 1,1' and insulation coverings 2,2' provided for outer periphery of the conductors 1,1' are connected in parallel along a longitudinal direction, where the insulation coverings 2,2' in the plurality of electric wires 5,5' are integrally formed of substantially homogenous polytetrafluoroethylene resin, and the plurality of electric wires 5,5' are connected without a gap along a longitudinal direction. The parallel electric wire 10 in which the insulation coverings 2,2' in the plurality of electric wires 5,5' consists of PTFE containing no melting and flowing component. The parallel electric wire 10 in which a bridge part 3 that connects the plurality of electric wires 5,5' with each other and is thinner than the external diameter of the electric wires 5,5' is formed between the electric wires 5,5'.SELECTED DRAWING: Figure 1
