Abstract

The invention discloses a spliced conductor type cable. The spliced conductor type cable comprises a plurality of conductors, inner insulating layers wrap wires and are twisted around a center, and an outer insulating layer wraps the whole cable; the conductors are formed by twisting the inner conductors and the outer conductors, the cross sections of the inner conductors are circular, the inner conductors are formed by a plurality of core wires of which the cross sections are semicircular or of a sector shape, the cross sections of the outer conductors are of a circular ring shape, the outer conductors and the inner conductors are spliced to form circular cross sections, and the outer conductors are formed by splicing a plurality of core wires of which the cross sections are of a tile shape. According to the spliced conductor type cable, the core wires are machined into the semicircular shape or the sector shape or the tile shape which can be spliced to the circular shape, then, the core wires are twisted together to produce the wires, and therefore gaps among the core wires are reduced, the compaction degree of the wires is increased, and the geometric dimensions of the wires are reduced.

Description

A kind of splicing conductor type cable

Technical field

The present invention relates to the cable technology field, relate in particular to a kind of splicing conductor type cable.

Background technology

Cable normally forms by multiple conducting wires is stranded, and every wire is provided with inner insulating layer outward, and is twisted into round the Yi Gen center, and whole outside is surrounded by the cover layer of high-insulation.And every wire is by many stranded the forming of heart yearn.In prior art, every core section is circular, when many heart yearns are stranded, between heart yearn and heart yearn, can produce gap, causes the compression degree inadequate, makes the wire physical dimension larger, takies larger use area, urgently improves.

Summary of the invention

The problem existed for prior art, the object of the invention is to propose a kind of splicing conductor type cable, to improve the compression degree of wire, reduces the wire physical dimension.

A kind of splicing conductor type cable comprises:

Many conductors, described wire is coated with inner insulating layer, and is twisted into round the Yi Gen center, and whole outside coats external insulation layer;

Described conductor is by inner wire and outer conductor is stranded forms, described inner wire cross section is circular, by a plurality of cross sections, is that semicircle or fan-shaped heart yearn form, and described outer conductor cross section is annular, and with form circular cross-section after the splicing of described inner wire, by the heart yearn of a plurality of watts of tee sections, be spliced.

Preferably, be provided with interior wire armoring between described wire and described external insulation layer.

In the present invention, heart yearn is processed into and can splices conglobate semicircle, fan-shaped or watt shape, then twist together and make wire, reduced can produce gap between heart yearn and heart yearn, improve the compression degree of wire, reduce the wire physical dimension.

The accompanying drawing explanation

Fig. 1 is a kind of splicing conductor type cross-section of cable figure in the embodiment of the present invention.

Reference numeral:

1, inner wire; 2, outer conductor; 3, inner insulating layer; 4, armour; 5, external insulation layer.

Embodiment

Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by embodiment:

As shown in Figure 1, Fig. 1 is a kind of splicing conductor type cross-section of cable figure in the embodiment of the present invention.

With reference to Fig. 1, the embodiment of the present invention provides a kind of splicing conductor type cable, comprising: many conductors, and described wire is coated with inner insulating layer 3, and is twisted into round the Yi Gen center, and whole outside coats interior wire armoring 4 and external insulation layer 5 successively.Wherein, conductor is by inner wire 1 and outer conductor 2 is stranded forms, and inner wire 1 cross section is circular, by a plurality of cross sections, be that semicircle or fan-shaped heart yearn form, outer conductor 2 cross sections are annular, and with inner wire 1 splicing after form circular cross-section, by the heart yearn of a plurality of watts of tee sections, be spliced.This heart yearn connecting method, reduced can produce gap between heart yearn and heart yearn, improves the compression degree of wire, reduces the wire physical dimension.

The embodiment of the present invention provides the above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.

Claims (2)

1. a splicing conductor type cable, is characterized in that, comprising:

Many conductors, described wire is coated with inner insulating layer, and is twisted into round the Yi Gen center, and whole outside coats external insulation layer;
