Abstract
The utility model relates to a multi-core control cable against radiation, which belongs to a cable. The utility model solves the technical problems of low temperature resistance, poor performance of resisting electromagnetic interference, large specific density, poor flexibility, etc. existing in similar cables. The multi-core control cable against radiation has the technical scheme that the periphery of a conductive core wire twisted by tinned copper conducting wires is coated with an insulating plastic layer, and the periphery of the insulating plastic layer is wrapped with an aluminium-plastic composite film layer; the periphery of the aluminium-plastic composite film layer is wrapped with a polyimide film layer to form core cables, and three or more than three core cables are mutually and closely contacted or a multi-core cable is twisted; the periphery of the multi-core cable is orderly wrapped with the aluminium-plastic composite film layer and the polyimide film layer from inside to outside, the periphery of the polyimide film layer is provided with a PVC cold-resisting sheath of an elastic body, and a current guiding wire can be embedded in the multi-core cable. The utility model is mainly used for the connection of electric appliances in a ground control system or an outer space environment, the cable can resist cosmic rays, and simultaneously, the multi-core control cable against radiation has the advantages of high performance of resisting electromagnetic interference, high temperature resistance, small specific density and favorable flexibility.
Description
Technical field
The utility model relates to the cable that a kind of electrical equipment that is used for ground control system or space environment connects.
Background technology
At present, be used for this type of cable of the electrical equipment connection of ground control system or space environment, heatproof is lower, is generally below 70 ℃, and anti-electromagnetic interference capability generally also has only 60dB, and stupid heavy, and flexibility is poor.
Summary of the invention
The purpose of this utility model provides that a kind of proportion is little, flexibility good, can be used for the radioresistance multi-core controlled cable that the electrical equipment of ground control system or space environment connects.
The technical scheme that its technical problem that solves the utility model adopts is: the periphery coated insulation plastic layer 3 of the conductive core line 4 that is twisted into by the tin-coated copper lead, the wrapped plastic-aluminum combined thin layer 2 of the periphery of ambroin layer 3, the wrapped polyimide film layer 1 of the periphery of plastic-aluminum combined thin layer 2 constitutes the core cable, core cable more than 3 or 3 is close to mutually or is twisted into multicore cable, wrapped successively from the inside to the outside plastic-aluminum combined thin layer 5 of the periphery of multicore cable and polyimide film layer 6, the periphery of polyimide film layer 6 are provided with the cold-resistant sheath 8 of elastomer PVC.But setting-in channelizing line 7 also in the multicore cable.
The beneficial effects of the utility model are: it is compared with former use product, and heatproof is brought up to 200 ℃ from 70 ℃, and anti-electromagnetic interference capability is brought up to 80dB from 60dB, weight saving 20%, and flexibility improves 30%.The electrical equipment that it is mainly used in ground control system or space environment connects, the anti-cosmic ray of cable energy, and anti-electromagnetic interference capability is strong simultaneously.
Description of drawings
Fig. 1 is a cross-sectional structure schematic diagram of the present utility model.
Embodiment
The periphery coated insulation plastic layer 3 of the conductive core line 4 that is twisted into by the tin-coated copper lead, described ambroin layer 3 adopts fluoroplastics, the wrapped plastic-aluminum combined thin layer 2 of the periphery of ambroin layer 3, the wrapped polyimide film layer 1 of the periphery of plastic-aluminum combined thin layer 2 constitutes the core cable, the core cable of (preferably 5-100 root) is close to mutually or is twisted into multicore cable more than 3 or 3, but setting-in channelizing line 7 also in the multicore cable, wrapped successively from the inside to the outside plastic-aluminum combined thin layer 5 of the periphery of multicore cable and polyimide film layer 6, the periphery of polyimide film layer 6 are provided with the cold-resistant sheath 8 of elastomer PVC.The electrical equipment that it is mainly used in ground control system or space environment connects, the anti-cosmic ray of cable energy, and anti-electromagnetic interference capability is strong simultaneously.It is compared with former use product, and heatproof is brought up to 200 ℃ from 70 ℃, and anti-electromagnetic interference capability is brought up to 80dB from 60dB, weight saving 20%, and flexibility improves 30%.Its rated voltage: 120V and following, temperature range :-40 ℃～+ 200 ℃.
