Abstract

A copper clad aluminum core silicon rubber insulation flat type flexible cable belongs to the field of control cables. The inner layer of the flexible cable comprises a plurality of round conductor cores; each round conductor core adopts a design mode that a copper layer is concentrically coated on an aluminum core so as to closely integrate copper and aluminum surfaces; an insulation layer is coated outside the conductive core, and an outer protection layer is coated outside the insulation layer; and the outer protection layer is made of silicon rubber material. The copper clad aluminum core silicon rubber insulation flat type flexible cable has the beneficial effects of lowering the production cost, saving resources and being beneficial to restricting copper price as a copper clad aluminum core is adopted as the conductive core instead of a pure copper core.

Description

The flat type flexible cable of copper-covered aluminum-core silicon rubber insulation

Technical field

The utility model relates to the flat type flexible cable of copper-covered aluminum-core silicon rubber insulation, belongs to the control cable field.

Background technology

Cable is widely used in the every field of productive life, and cable commonly used is several copper core outsourcing insulating layer coatings, is shaped as flat.With respect to round cable, flat cable has advantages such as the installing space of saving and cost, and its bending radius is littler than round cable under the identical situation of core radical.

General flat cable all is by the multicore round conductor, behind the extruded insulation layer, the multicore core is parallel to extrude that outer jacket forms, described round conductor core is that fine copper is made, because World Economics and fast development of Chinese economy, supply falls short of demand in global copper market, China uses copper big country in addition, demand situation to copper is powerful, and the internal copper demand is very outstanding greater than the contradiction of supplying with, and causes the copper price to rise.Because it is higher that copper material accounts for the production cost of such cable, therefore cause the material cost of this cable significantly to increase, the operated pressure of enterprise is big.

Summary of the invention

In view of the defective that prior art exists, it is few that the purpose of this utility model provides a kind of copper consumption, the flat type flexible cable of the copper-covered aluminum-core silicon rubber insulation that cost is low.

For achieving the above object, the technical solution that the utility model adopted is: the flat type flexible cable of copper-covered aluminum-core silicon rubber insulation, its internal layer comprises the multicore round conductor, every round conductor core adopts the design that coats the copper layer on the aluminium core with one heart, and copper aluminium interface is closely merged, be coated with insulating barrier in conductive cores, insulating barrier is outward an outer jacket.

Described outer jacket is to be made by silastic material.

The flat type flexible cable of copper-covered aluminum-core silicon rubber insulation, its beneficial effect is: conductive cores replaces the fine copper core with copper-covered aluminum-core, reduces production costs, and economizes on resources, and helps suppressing the copper valency simultaneously.
