Abstract

The utility model relates to a scalable wire or cable, comprising a wire or a cable. The utility model is characterized in that a scalable elastic rubber strip is spirally wound by a wire core of the wire or the cable, an elastic insulation layer or an elastic sheath is arranged outside. The utility model has the advantages that the wire or cable is scalable to some extent in length, thus the problem that the wire or cable is liable to be broken due to tension or frequent curvature during usage is completely solved; the utility model is also applicable to aviation, marine, machinery and military field and the like.

Description

Scalable electric wire, cable

Technical field

The utility model belongs to a kind of electric wire, particularly a kind of scalable electric wire, cable.

Background technology

Electric wire is used very extensive as the conductor of electric energy, but because this not flexible on length, in particular cases use at some and to be subjected to restriction, caused inconvenience, for example in the use of mining electric cable for coal mining machine, because cable is along with equipment constantly comes and goes, make cable be in the bending motion of S shape all the time, because cable interior curve radius is too small, core is subjected to pulling force excessive, often cause the control line in the cable to be broken and can not use, produce and brought safely great influence to the mine.This problem is perplexing the producer of electric wire, cable and the user that the mine produces all the time for a long time.

The utility model content

The purpose of this utility model provides a kind of scalable electric wire, cable, thoroughly solves the problem that electric wire, cable not flexible in use and alternating bending are easily broken.

The purpose of this utility model is achieved by the following technical solution: it comprises electric wire or cable, it is characterized in that: the core of electric wire or cable is spirally wound on the telescopic elastic adhesive tape, and elastic insulating layer or flexible sheath externally are set.

The utility model has the advantages that: electric wire or cable have certain retractility on length, thereby have thoroughly solved the problem that electric wire in use stretches or alternating bending is easily broken.It also is applicable to fields such as aviation, marine ship, machinery and military affairs.

Description of drawings

Fig. 1 is a wire structure schematic diagram of the present utility model.

Fig. 2 is a construction of cable schematic diagram of the present utility model.

Embodiment

See Fig. 1, wire structure of the present utility model is as follows: electric wire core 2 is spirally wound on the telescopic elastic caoutchouc adhesive tape 1, and elastic insulating layer 3 externally is set.

See Fig. 2, the construction of cable of the present utility model is as follows: cable core 2 is spirally wound on the telescopic elastic caoutchouc adhesive tape 1, and flexible sheath 3 externally is set.

Above-mentioned electric wire, cable are when being subjected to pulling force, and adhesive tape, spiral helicine electric wire, cable core and flexible sheath can both stretch or shrink, thereby have avoided electric wire, cable core to be broken.

Claims (1)

1, a kind of scalable electric wire, cable, it comprises electric wire or cable, it is characterized in that: the core of electric wire or cable is spirally wound on the telescopic elastic adhesive tape, and elastic insulating layer or flexible sheath externally are set.
