Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

The purpose of the utility model is to provide a kind of central air-conditioning dedicated wires, are prevented by winding band in conducting wire periphery Conducting wire because extraneous factor influence due to damage, between band and bundle conductor be arranged filler prevent conducting wire deformed because of bending and oneself Body generates heat and damages, and to solve existing air-conditioning electric wire poor corrosion resistance, easy adhesion of generating heat bends easily-deformable problem.

To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have Body embodiment is described in further detail the utility model.

Embodiment 1:

A kind of central air-conditioning dedicated wires provided in this embodiment, as depicted in figs. 1 and 2, including by five conducting wires aggregations The bundle conductor 1 of composition, diameter of wire are respectively two 2.5mm²With three 0.75mm², the conductive core 11 of each wire is all by polychlorostyrene Ethylene insulating layer 12 wraps up, and while guaranteeing wire insulation, and conducting wire softness is made to have good extensibility, bundle conductor 1 Periphery one layer of belting layer 2 of package, belting layer 2 is a band made of polyethylene, and band is spirally wound on outside bundle conductor 1 It encloses, belting layer 2 can protect bundle conductor not corroded, and have fastening effect to bundle conductor, exempt extraneous factor to bundle conductor It influences, between five conducting wires, filler 3 is filled between conducting wire and belting layer 2, filler 3 is the interconnection of a plurality of filling tape The reticular structure of composition, material are halogen-free low-smoke flame retardant material, these materials have good heat-proof quality, by reticular structure It shrinks bunchy to be filled between conducting wire and conducting wire, between conducting wire and belting layer 2, separating conductive wires, netted knot can be played the role of Structure makes each gap that can will not shift, have because of the interaction between conducting wire full of filler, filler Prevent to effect conducting wire because of the generation of stick to each other auto-ignition caused by self-heating, while filler 3 is by all gaps It fills up, so that line body more rounding is beautiful, will not deform after external force bending, in periphery one strata of package of belting layer 2 The sheath 4 of vinyl chloride material can not only play a protective role to the entirety of electric wire, moreover it is possible to keep electric wire more soft, be not easy to send out It is raw damaged, the service life of extending wire.

In a kind of central air-conditioning dedicated wires provided in this embodiment, in order to protect conducting wire not corroded, exempt extraneous Influence of the factor to bundle conductor, the band made of the spiral winding polyethylene of bundle conductor periphery, plays a protective role to bundle conductor.

In other embodiments, the material of band can be other corrosion-resistant materials such as non-woven fabrics or fiberglass cloth material Material, the mode of winding can also be vertical package, naturally it is also possible to plastic packaging layer and network-like package structure be wrapped up outside bundle conductor, only It wants that bundle conductor can be protected to damage from the influence of extraneous factor, and fastening effect is played to bundle conductor, it is practical new at this In the range of type protection.

In a kind of central air-conditioning dedicated wires provided in this embodiment, in order to protect conducting wire mutual not because of self-heating Influence of the oneself factor to bundle conductor is exempted in adhesion spontaneous combustion, and keeps line body more rounding beautiful, and bending is unlikely to deform, in conducting wire The filler made of halogen-free low-smoke flame retardant material is filled in gap between conducting wire, between conducting wire and band, and will filling Object is arranged to reticular structure, specifically, as shown in figure 3, can be by paper fillers paper made of a halogen-free low-smoke flame retardant material Alternating straggly scratches several openings, and by paper fillers cross directional stretch, paper fillers are just provided with reticular structure, and paper fillers are filled into In gap between conducting wire and conducting wire, between conducting wire and band, so that all there is filler, and filler around each conducting wire It will not shift because of the interaction between conducting wire, effectively prevent the stick to each other that conducting wire is generated by self-heating The problem of spontaneous combustion, but also even closer between conducting wire, line body more rounding is beautiful, and bending is unlikely to deform.

In other embodiments, the material of filler can also using glass fiber material or bast-fibre material etc. other Thermal resistance fire proofing, reticular structure are also possible to the network that filler is woven into, as long as can guarantee to have between conducting wire good Thermal insulation layer, and filler will not shift because of the interaction between conducting wire, keep line body more rounding beautiful, bending On-deformable structure, in the range of the utility model is protected.

In use, selecting the electric wire for being suitble to that wire count need to be connect with this kind of central air-conditioning, central air-conditioning dedicated wires are pressed It is arranged according to reasonable wire laying mode, each conducting wire of central air-conditioning dedicated wires is connected by circuit diagram.
