Abstract
The utility model discloses a cable. The cable comprises a plurality of conductors, insulating layers wrapped around the outer sides of the conductors, filler, a wrapping layer and a sheath layer. The conductors and the insulating layers form insulated wire cores; the wrapping layer is wrapped around the outer surfaces of the insulated wires; the filler is disposed in a gap among the insulating layers and the wrapping layer; the sheath layer is wrapped around the outer surface of the wrapping layer; the insulating layers are wound around the outer surfaces of the conductors in a spiral manner and form a plurality of spiral rings; an overlap part is formed between every two adjacent spiral rings; and one surface, which faces the corresponding conductor, of each insulating layer is provided with a glue layer. With the overlap parts, the sealing performance between the spiral rings is improved; the glue layers can prevent the spiral rings from slipping and thus exposing the conductors and causing potential safety hazards. For manufacturing a cable end, one can peel off the insulating layers from ends of the insulating layers and expose the conductors for a certain length. Therefore, one can peel off the insulating layers with hands for manufacturing a cable head and cutting of the conductors is not needed so that the cable head can be manufactured easily.

Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of cable, this cable has changed the structure of insulating barrier, between any two adjacent spiral coils, form overlapping portion, make energy close contact between two adjacent spiral coils, improve the sealing between spiral coil, be provided with glue layer at insulating barrier with respect to conductor one end, prevent that spiral coil slippage from making the exposed potential safety hazard that out causes of conductor, in the time that needs are made cable end, can tear stripping from the termination of insulating barrier, make conductor exposed to certain length, unnecessary insulating barrier can tear and also can still be wound on conductor outer surface, so in the time making cable end, not by instrument in the situation that, just can use hand stripping of insulatin layer, can not produce the situation of cutting off conductor, the convenient cable end of making.
For achieving the above object, the utility model provides following technical scheme: a kind of cable, comprise some conductors, be coated on the insulating barrier of every conductor outside, filler, lapping layer and restrictive coating, described conductor and insulating barrier form insulated wire cores, described lapping layer is wrapped in the outer surface of some insulated wires, described filler is filled in the space between insulating barrier and lapping layer, described restrictive coating is located at the outer surface of lapping layer, described insulating barrier helically is wound on the outer surface of conductor and forms multiple spiral coils, between any two adjacent spiral coils, form overlapping portion, described insulating barrier is simultaneously provided with glue layer with respect to conductor.
By adopting technique scheme, between any two adjacent spiral coils, form overlapping portion, make energy close contact between two adjacent spiral coils, improve the sealing between spiral coil, be provided with glue layer at insulating barrier with respect to conductor one end, prevent that spiral coil slippage from making the exposed potential safety hazard that out causes of conductor, in the time that needs are made cable end, can tear stripping from the termination of insulating barrier, make conductor exposed to certain length, unnecessary insulating barrier can tear and also can still be wound on conductor outer surface, so in the time making cable end, not by instrument in the situation that, just can use hand stripping of insulatin layer, can not produce the situation of cutting off conductor, the convenient cable end of making.
The utility model is further set to: described restrictive coating outer surface is provided with several and is convenient to tear the depressed part of stripping.
The utility model is further set to: described depressed part is the semicircular arc groove circle that is arranged on restrictive coating outer surface.
By adopting technique scheme, be provided with several at restrictive coating outer surface and be convenient to tear the depressed part of stripping, not by external tool in the situation that, can fasten depressed part with finger and tear off restrictive coating.
The utility model is further set to: described glue layer is silicone based adhesive phase.
By adopting technique scheme, what glue layer was coated with is silicone based adhesive, and this adhesive has good waterproof effect, in the time that cable is dipped in water, can block water enters into and in insulating barrier, prevents cable short circuit; Adopt this adhesive, when after insulating barrier strip off, still insulating barrier can be adhered on conductor, reusable.
The utility model is further set to: described filler is to be made up of the non-net polypropylene tearing material of opening.
By adopting technique scheme, filler adopts the non-net polypropylene tearing material of opening to form, and can increase the resistance to wear of insulating barrier and restrictive coating.
