Description
Technical field
The utility model is related to Aviation cable field, more particularly to a kind of shielding type cable.
Background technology
The electric wire used under the hot environment of aerospace, existing method is the thick insulating layer of setting, this
Structural volume is big, weight is heavy and insulation is easy cracking aging due to high-energy electron radiation in the outer space, and safety and reliability are poor.
Invention content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of shielding type cable, which sets
It counts reasonable, simple in structure, has the advantages that small, shield effectiveness is good.
Technical solution used by the utility model is:A kind of shielding type cable, is characterized in that, the first insulated wire cores
It is made of the first conductor and the inner insulating layer and external insulation layer that are wrapped in successively outside the first conductor, the second insulated wire cores, third are exhausted
Edge core, the 4th insulated wire cores are respectively made of multiple conductors and inner insulating layer, and multiple conductors therein are arranged in fan-shaped,
Multiple conductors are wrapped with fan-shaped insulating layer, and the first insulated wire cores insulate with an end face of the second insulated wire cores, the 4th respectively
One end face of core is tangent, third insulated wire cores respectively with another end face of second insulated wire cores adjacent with it, third
Another end face of insulated wire cores is in contact;It is equipped with groove in the inner surface of the inner insulating layer, in the interior table of external insulation layer
Face also is provided with groove, and metal coating is coated respectively in groove;Four insulated wire cores twist together after again on the outside of them
It is enclosed with establishment shielded layer, inner restrictive coating, armouring shielded layer and external sheath layer successively, between inner sheath and armouring shielded layer also
Equipped with an at least drainage thread.
The utility model has the beneficial effects that:The shielding type cable, the insulated wire cores of built-in two kinds of different-diameters, wherein one
A insulated wire cores are externally provided with the inner insulating layer and external insulation layer for being coated with metal coating, the structure of this conductor shape component shields,
Substantially increase shield effectiveness.The insulating layer of the other three insulated wire cores is set as fan-shaped, and is in contact two-by-two, peripheral surface shape
At sector, and it is tangent with circular cable, it ensure that the roundness of insulated wire cores, so that each core position is stablized constant, improve
The stability of cable;An at least drainage thread is additionally provided between inner sheath and shielded layer, it can be ensured that shielded layer after laying and
In long-time service, excellent interference free performance is remained, meet bonding requirement.
