CN202049771U - Double-layer insulating cable - Google Patents

Abstract

The utility model discloses a double-layer insulating cable, which comprises a cable core positioned in a center. An F46 (fluorinated ethylene propylene) insulating layer tightly covers the outside of the cable core, and a PE (polyethylene) insulating layer tightly covers the outside of the F46 insulating layer. The designed double-layer insulating cable adopts the F46 insulating layer positioned at the inside and the PE insulating layer positioned at the outside; the performance of the F46 insulating layer is more fragile, but enough hardness can be provided, and the damage can be prevented; however, the PE insulating layer has a smooth and even surface and can be resistant to friction and scratch; and furthermore, as a PE material has good toughness, the PE insulating layer can be resistant to stretch and has a good shaping effect. Therefore, by using the double-layer insulating cable provided by the utility model, the advantages of an F46 insulating material and a PE insulating material can be combined simultaneously, and the cable core can be effectively prevented from being damaged due to external force.

Description

A kind of double-insulated cable

Technical field

The utility model relates to a kind of insulated cable.

Background technology

Insulated cable commonly used all is simple to set up a layer insulating in the cable core outside, this insulating barrier generally adopts the PE material, because PE material itself is soft, toughness is big, but the PE material can not provide enough hardness, so external force is rigid collides with cable the time in case have, be easy to pass the PE insulating barrier and be damaged to cable core.

The utility model content

The purpose of this utility model is to provide a kind of double-insulated cable, and the PE single layer of material insulation layer structure that solves present customary insulation cable can not provide enough intensity, is subjected to external force easily and damages the problem of cable core.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of double-insulated cable comprises the cable core that is positioned at the center, tightly coats one deck F46 insulating barrier in the cable core outside, tightly coats one deck PE insulating barrier in the outside of F46 insulating barrier.

Double-insulated cable through above-mentioned design, adopted and be positioned at inner F46 insulating barrier and be positioned at outside PE insulating barrier, F46 insulating barrier performance is more crisp, but can provide enough hardness, can prevent damage, and the PE surface of insulating layer is smooth, smooth, can rub resistance, scratch resistance rubs, and because the PE toughness of material is good, can stretch-proof, it is effective to finalize the design, so the double-insulated cable that the utility model provides, can simultaneously comprehensive F46 and the advantage of two kinds of insulating material of PE, can effectively prevent the damage that cable core causes owing to external force.

Description of drawings

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

Fig. 1 is the structure chart of the described double-insulated cable of the utility model embodiment.

Embodiment

As shown in Figure 1, double-insulated cable described in the utility model comprises the cable core 1 that is positioned at the center, tightly coats one deck F46 insulating barrier 2 in the cable core outside, tightly coats one deck PE insulating barrier 3 in the outside of F46 insulating barrier 2.

Double-insulated cable through above-mentioned design, adopted and be positioned at inner F46 insulating barrier and be positioned at outside PE insulating barrier, F46 insulating barrier performance is more crisp, but can provide enough hardness, can prevent damage, and the PE surface of insulating layer is smooth, smooth, can rub resistance, scratch resistance rubs, and because the PE toughness of material is good, can stretch-proof, it is effective to finalize the design, so the double-insulated cable that the utility model provides, can simultaneously comprehensive F46 and the advantage of two kinds of insulating material of PE, can effectively prevent the damage that cable core causes owing to external force.

Claims (1)

1. a double-insulated cable comprises the cable core that is positioned at the center, it is characterized in that, tightly coats one deck F46 insulating barrier in the cable core outside, tightly coats one deck PE insulating barrier in the outside of F46 insulating barrier.
