Detailed Description

Referring to fig. 1 and 2: the utility model relates to an integrated cable for communication vehicle, integrated cable includes conductor 1, insulating layer 2, around covering 4, weaving layer 5 and outer jacket 6.

The conductors 1 are multiple, and the multiple silver-plated copper wires are twisted in a regular arrangement and twisting mode at a pitch (preferably, 12 times pitch) which is 11-12 times, so that the flexibility is improved, and the processing is not influenced.

The insulating layer 2 made of fluorine-containing polymer film is wrapped outside each conductor 1 to form an insulating wire core,

the insulated wire cores are multiple, are twisted in a regular arrangement twisting mode in a pitch (preferably, 10 times of pitch) which is 10-11 times, so that the flexibility is improved, and the processing is not influenced.

The whole body formed by twisting the insulated wire cores is wrapped with a wrapping layer 4 made of raw material belts, namely a cable core is formed,

the braided layer 5 (with shielding function) is braided outside the cable core by adopting a silver-plated copper wire,

the outer protective layer 6 is made of flame-retardant thermoplastic polyether type polyurethane elastomer and is wrapped outside the woven layer 5.

The embodiment has good high-temperature resistance and good flexibility as a whole.

Specifically, the method comprises the following steps: firstly, the insulating layer 2 made of a fluorine-containing polymer film has good high-temperature resistance; adopt the raw material area to make around covering 4, have insulating, high temperature resistant, low temperature resistant performance, both (insulating layer 2 with around covering 4) cooperation use, can greatly improve the high temperature resistant performance of composite cable. Secondly, the conductors 1 are multiple, and the multiple silver-plated copper wires are twisted in a regular arrangement and twisting mode at a pitch which is 11-12 times that of the silver-plated copper wires, so that the conductors 1 have good flexibility; the insulating layer 2 made of a fluorine-containing polymer film is wound outside each conductor 1 to form an insulating wire core, the traditional insulating extrusion molding structure is replaced, and in addition, the insulating layer 2 has the flexibility, so that each insulating wire core has good flexibility; the cable is characterized in that the number of the insulated wire cores is multiple, and the insulated wire cores are twisted in a regular arrangement and twisting mode at a pitch of 10-11 times, so that the whole insulated wire cores have good flexibility, and the cable core formed by the wrapping layer 4 also has good flexibility; the braided layer 5 also has certain soft performance; the outer protective layer 6 is made of flame-retardant thermoplastic polyether polyurethane elastomer, and has good flexibility, wear resistance, good elasticity, chemical resistance, environmental resistance and the like. It can be seen that the conductor 1, the insulating layer 2, the insulated wire core, the cable core, the wrapping layer 4, the braid layer 5, the outer sheath 6, and the like are used in combination, so that the electric composite cable has excellent flexibility as a whole and has balanced flexibility.

The composite cable further comprises a reinforcing part 3 (the reinforcing part 3 of the embodiment is only required to be an existing mature filling rope), and the reinforcing part 3 is filled in the stranding gap between the insulated wire core and the insulated wire core. So as to increase the tensile strength of the whole electric composite cable. Preferably, the reinforcing member 3 is made of aramid filaments.
