Abstract

The utility model relates to a kind of 400 DEG C of shielding flexible cords of high temperature resistant, including the heatproof separation layer and silver-coated copper wire woven shield composition of the Kapton insulating layer, alkali-free glass wool braiding that outside the conductor that multiply silver-coated copper wire is constituted, are successively arranged.The utility model beneficial effect is: conductor uses more silver-coated copper wires, has excellent conductive capability, reduces the resistance of conductor.Insulating layer uses Kapton, demonstrate,proves with excellent electric property.One layer of alkali-free glass wool braiding heatproof separation layer is externally provided with using in Kapton insulating layer, using the thermal insulation of glass braid, control the temperature of insulating layer Kapton at 400 DEG C or less, it is not damaged with guaranteeing to work normally, to achieve the purpose that make cable to be used for a long time at 400 DEG C.Such structure have it is light-weight, outer diameter is small, soft, bending radius is small, 400 DEG C of high temperature resistant, can small space, heatproof occasion and have Weight control require occasion use.

Description

A kind of 400 DEG C of shielding flexible cords of high temperature resistant

Technical field

It is that signal passes in the high-temperature systems with Mr. Yu's signal equipment the utility model relates to 400 DEG C of shielding flexible cords of high temperature resistant Defeated cable.

Background technique

Currently used in certain signal equipment high-temperature systems signal transmit cable, generally common temperature-resisting cable, be by Conductor, insulating layer form the working portion of cable, then the insulating portion of cable is made of glass cloth tape and mica tape, and outermost layer is also Sheath is needed to protect glass cloth tape and mica tape, cable overall dimensions are big, weight is heavy, occupied space is big, are not easy to pacify Dress operation.

Summary of the invention

In view of situation of the existing technology, the utility model connects between the system Instrumental that reaches a high temperature and signal passes The defeated requirement used, provides 400 DEG C of shielding flexible cords of high temperature resistant, and it is small, light-weight that this cable meets 400 DEG C of high temperature resistant, outer diameter, The requirement for facilitating installation to operate.

The utility model to achieve the above object, is adopted the technical scheme that: a kind of 400 DEG C of shielding flexible cords of high temperature resistant, It is characterized by comprising the Kapton insulating layers outside the conductor that multiply silver-coated copper wire is constituted, being successively arranged, alkali-free glass The heatproof separation layer and silver-coated copper wire woven shield of glass silk braiding are constituted.

The beneficial effects of the utility model are: conductor uses more silver-coated copper wires, there is excellent conductive capability, reduce The resistance of conductor has good weldability.Insulating layer uses Kapton, has excellent electric property, lower Dielectric constant be it is low decaying, low capacitor basic assurance.Conventional polyimide film insulating cable is able to satisfy long-term at 300 DEG C It uses, is used no more than at 350 DEG C 5 minutes, otherwise will form heat ageing, reduce insulation performance, it can be by when reaching 400 DEG C Step carbonization is failed and is decomposed, and the utility model is resistance to using one layer of alkali-free glass wool braiding is externally provided in Kapton insulating layer Warm separation layer, using the thermal insulation of glass braid, make the temperature of insulating layer Kapton control 400 DEG C with Under, it is not damaged with guaranteeing to work normally, to achieve the purpose that make cable to be used for a long time at 400 DEG C.

Shielded layer effectively prevent the interference of outer bound pair cable using braiding silver-coated copper wire form.

Such structure has that light-weight, outer diameter is small, soft, bending radius is small, 400 DEG C of high temperature resistant, can be in small space, resistance to The occasion that thermal field closes and has Weight control to require uses.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

As shown in Figure 1, a kind of 400 DEG C of shielding flexible cords of high temperature resistant, the conductor 1 constituted including multiply silver-coated copper wire, polyamides are sub- The heatproof separation layer 3 and silver-coated copper wire woven shield 4 that amine thin dielectric film 2, alkali-free glass wool weave.

The wrapped strata imide membrane insulating layer 2 outside the conductor 1 that multiply silver-coated copper wire is constituted, in Kapton 2 external application alkali-free glass wool of insulating layer weaves one layer of heatproof separation layer 3, and one layer of silver-coated copper wire braiding is woven outside heatproof separation layer 3 Shielded layer 4.

Claims (1)

1. a kind of 400 DEG C of shielding flexible cords of high temperature resistant, it is characterised in that: outside including the conductor (1) that is constituted in multiply silver-coated copper wire, according to The heatproof separation layer (3) and silver-coated copper wire braid shielded that the secondary Kapton insulating layer (2) being equipped with, alkali-free glass wool weave Layer (4) is constituted.
