Abstract

The utility model relates to a wear-resistant electric wire, which comprises an insulating layer and a conductive core wire arranged in the insulating layer, and a wear-resistant coil is wound on the external surface of the insulating layer. The utility model has the advantages of high wear resistance, low production cost and the like.

Description

A kind of abrasion resistant electrical wire cable

Technical field

The utility model belongs to the telecommunication apparatus technical field, especially relates to a kind of abrasion resistant electrical wire cable.

Background technology

Electric wire is at the widely used material of occasions such as electric power, communication, is user's requisite material in using electric process.Along with the extensive use of electric power, electric wire also is applied in various operational environments thereupon.Because therefore the difference and the variation of operational environment have also just proposed requirement in various degree to the electric wire service behaviour.Such as: in the comparatively cold place of weather, what often need is the electric wire with winter protection, antifreeze function; In the higher place of temperature, then require the higher electric wire of fusing point is installed, in case electric wire melts easily, cause situations such as electric leakage.At the construction field (site) or other use occasions, electric wire usually will be pulled and hauled a man inevitably, to frequently rub with ground or other body surfaces, can make electric wire outer surface generation wearing and tearing in various degree, particularly in the abominable job site of environment, the wearing and tearing of electric wire outer surface are especially serious.At present, it is not very good having the still less and wear-resisting effect of the low electric wire of good abrasion resistance and cost, and some enterprises have adopted special material in order to produce the strong electric wire of resistance to wear, obviously increased production cost like this, economy that neither be very concerning the numerous common people.

Summary of the invention

The purpose of this utility model is the problems referred to above that exist at prior art, and a kind of simple in structure, resistance to wear is strong, production cost is low abrasion resistant electrical wire cable is provided.

The purpose of this utility model realizes by following technical proposal:

A kind of abrasion resistant electrical wire cable comprises the electric wire body, and this electric wire body comprises insulating barrier and the conductive core line of the portion that sets within it, and in the solderless wrapped connection of insulating barrier outer surface wear-resisting coil is arranged.

Further, described wear-resisting coil twist solderless wrapped connection at the insulating barrier outer surface.

Further, adopt bonding between described insulating barrier and the wear-resisting coil or hot melting way is connected.

Further, described insulating barrier and wear-resisting coil adopt same material to make, and preferred, insulating barrier and wear-resisting coil all adopt the PVC material to make.

Further, the long-pending ratio of the cross-sectional area of described wear-resisting coil and electric wire body cross-section is 1: (4.5-6.5).Formed pitch length of described wear-resisting coil and electric wire body maximum outside diameter length ratio are (3-5): 1.

Adopt abrasionproof electric wire of the present utility model, though simple in structure, its effect is extremely significant.By outside the common wiring cable insulation, increasing wear-resisting coil, can strengthen the anti-wear performance of electric wire greatly, effectively reduced contacting of insulating barrier and other objects.Simultaneously, in the technical program, wear-resisting coil and insulating barrier can adopt identical materials, as can adopting good, the with low cost PVC material of resistance to wear, and wear-resisting coil and insulating barrier are linked into an integrated entity, both simplified production process, save material again, reduced production cost.

Because the wear-resisting coil that increases can significantly reduce the touch opportunity of insulating barrier and other objects, this just can greatly reduce the requirement of insulating barrier to material property, and can alternative costs lower material is as insulating layer material.Since electric wire be use very extensive, the product that involves the interests of the state and the people, under contemporary fierce market competition environment, cost is exactly the lifeline of enterprise, abrasion resistant electrical wire cable of the present utility model, can reduce the production cost of enterprise greatly, improve the market competitiveness of enterprise, have good market application prospect.

Description of drawings

Fig. 1 is that the master of the utility model embodiment looks schematic diagram;

Fig. 2 is the conductive core line schematic diagram of the utility model embodiment;

Fig. 3 is the cross section enlarged diagram of the utility model embodiment.

Among the figure; 1, insulating barrier; 2, conductive core line; 3, wear-resisting coil.

Embodiment

Shown in Fig. 1,2 and 3, a kind of abrasion resistant electrical wire cable, comprise the electric wire body, this electric wire body comprises insulating barrier and the some conductive core lines 2 of the portion that sets within it, in the present embodiment, the conductive core line 2 of insulating barrier 1 inside is provided with three, and insulating barrier 1 outer surface solderless wrapped connection has wear-resisting coil 3, this wear-resisting coil 3 twist solderless wrapped connection at insulating barrier 1 outer surface.

The thickness of wear-resisting coil and coil pitch size have relation with the thickness of electric wire and the site environment of use electric wire, wear-resisting coil is thick more, and wear-resisting coil pitch is more little, and its anti-wear performance is good more, but its cost is also just high more simultaneously, and the also corresponding increase of the weight of electric wire; Meticulous or the wear-resisting coil pitch of wear-resisting coil is excessive, then possibly can't play good wear-resisting effect, and the excessive insulating barrier that also will cause protecting electric wire of coil pitch.Therefore, take into account cost and anti-wear performance, as preferably, the cross-sectional area of wear-resisting coil is 1 with the ratio of the cross-sectional area of electric wire body: (4.5-6.5), the maximum outside diameter length ratio of formed pitch length of wear-resisting coil and electric wire body is (3-5): 1.

The insulating barrier of present embodiment and wear-resisting coil can adopt bonding or hot melting way links together.Insulating barrier and wear-resisting line 3 can adopt the identical materials manufacturing, as, all adopt the PVC made.Insulation 1 and wear-resisting line 3 adopt identical materials, can simplify production technology and reduce production costs.

The foregoing description only is enumerating the utility model design way of realization; protection range of the present utility model is not limited only to the foregoing description, and protection range of the present utility model may extend to those skilled in the art according to the thinkable equivalent technologies means of technical conceive of the present invention.
