Abstract

The utility model discloses a cable. The cable comprises a plurality of core conductors, each of which possesses an insulating layer, a wrapping layer outside each core conductor, a metal protective layer outside the wrapping layer, and an external protective layer outside the metal protective layer. The arrangement of the metal protective layer between the wrapping layer and the external protective layer of the utility model can strengthen total cable intensity so as to make sure that the cable can bear larger load and outside force. In addition, the metal protective layer of the utility model can prevent animals, such as mice from biting and damaging structure layers within the metal protective layer, for example wrapping layer, insulating layer, thereby providing better protection for cable.

Description

Cable

Technical field

The utility model relates to technical field of electricity, refers in particular to a kind of cable.

Background technology

Common cable, it includes some core conductors that abut one another, each core conductor is equipped with an insulating barrier, outside each core conductor, be provided with a lapping layer, outside this lapping layer, be provided with an outer jacket that adopts the PVC material preparation again, between each core conductor or be provided with filler such as asbestos etc.The intensity of the cable of said structure is less, ruptures easily when bearing bigger load or external force, influences the normal use of cable.In addition, this type of cable is subjected to mouse, ant and so on nibbling of animal easily and exposes core conductor, causes the problem of cable appearance such as short circuit.

So, have and need improve, to satisfy the needs in market to the structure of existing cable.

Summary of the invention

The purpose of this utility model is to solve the existing defective of existing cable, provides a kind of and bears than heavy load and external force, cable with better protection structure.

For achieving the above object; the utility model is by technical scheme as described below: a kind of cable; including a plurality of core conductors, that are equipped with insulating barrier is arranged at the outer lapping layer and of described core conductor and is arranged at the outer outer jacket of described lapping layer; wherein, be provided with a coat of metal between described outer jacket and the lapping layer.

In the above-mentioned cable, described coat of metal is the galvanized steel strip protective layer.

In the above-mentioned cable, fill out between described each core conductor and be provided with filler.

In the above-mentioned cable, described filler is the asbestos filler.

In the above-mentioned cable, described lapping layer is the glass fibre lapping layer.

In the above-mentioned cable, described lapping layer is the nonwoven fabrics lapping layer.

The beneficial effects of the utility model are: this cable is provided with a coat of metal between its lapping layer and outer jacket, can strengthen the bulk strength of cable, makes cable can bear bigger load and external force effect; In addition, because the setting of this coat of metal, can prevent the bad structure sheafs such as lapping layer within this coat of metal, insulating barrier that are positioned at of animal bites such as mouse, for cable provides better protection.

Fig. 1 is the structural representation of the utility model cable.

Embodiment

For making those of ordinary skill in the art be expressly understood the purpose of this utility model, technical scheme and advantage more, the utility model is further elaborated below in conjunction with drawings and Examples.

With reference to shown in Figure 1; cable disclosed in the utility model includes a plurality of core conductors 10; each core conductor 10 outer insulating barrier 20 that are provided with; each core conductor 10 abuts against together and is provided with a lapping layer 30 outside it; one coat of metal 40 is set outside lapping layer 30, is provided with an outer jacket 50 outside this coat of metal 40.The material that this insulating barrier 20 and outer jacket 50 can adopt existing cable to adopt--for example PVC material--preparation certainly, also can be adopted the suitable material such as other types such as polyolefin.

Preferably, can fill out between each core conductor 10 and establish filler 60, core conductor 10 firmly is set and makes the comparatively effect of rounding of cable profile to play, this filler 60 can select for use asbestos to make.

Each core conductor 10 of lapping layer 30 hard-pressed bales, to guarantee the tightness and the roundness of cable, it can adopt glass fibre or nonwoven fabrics preparation, has dampproof effect.

These coat of metal 40 preferred galvanized steel strips that adopt are made, and certainly, also can adopt such as materials such as copper strips and make.The utility model is provided with a coat of metal 40 between lapping layer 30 and outer jacket 50, can strengthen the bulk strength of cable, makes cable can bear bigger load and external force effect.In addition, because the setting of this coat of metal 40, can prevent the bad structure sheafs such as lapping layer 30 within this coat of metal 40, insulating barrier 20 that are positioned at of animal bites such as mouse, for cable provides better protection.

The above only is a preferred embodiment of the present utility model, but not the utility model is done any pro forma restriction.Those skilled in the art can impose various changes that are equal to and improvement on the basis of the foregoing description, all equivalent variations or modifications of being done in the claim scope all should fall within the utility model protection range.
