Abstract

The utility model discloses a spliced conductor type cable. The spliced conductor type cable comprises multiple conductors. Each of the conductors is externally wrapped with an internal insulating layer and is formed by intertwisting around a center. All the conductors are externally wrapped with an external insulating layer. Each of the conductors is formed by intertwisting an internal conductor and an external conductor. The cross section of each internal conductor is circular, and each internal conductor is formed by multiple core wires, the cross section of each of which is semicircle-shaped or fan-shaped. The cross section of each external conductor is circular ring-shaped, and the circular cross section is formed after each external conductor is spliced with the corresponding internal conductor. Each external conductor is formed by splicing multiple core wires, the cross section of each of which is tile-shaped. In the spliced conductor type cable, the core wires are processed to be semicircle-shaped, fan-shaped, or tile-shaped and can be spliced together to be circular. Then, the core wires are intertwisted together to form the conductors. In this way, gaps generated among the core wires are reduced; the compaction degree of the conductors is improved; and the geometry size of the conductors is decreased.

Description

A kind of splicing conductor type cable

Technical field

The utility model relates to cable technology field, relates 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 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 compression degree inadequate, makes wire physical dimension larger, takies larger usable floor area, urgently improves.

Utility model content

The problem existing for prior art, the purpose of this utility model is to propose a kind of splicing conductor type cable, to improve the compression degree of wire, reduces wire physical dimension.

A splicing conductor type cable, comprising:

Many conductors, described wire is coated with inner insulating layer, and is twisted into round Yi Gen center, and whole outside is coated 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 after the splicing of described inner wire, form circular cross-section, by the heart yearn of a plurality of watts of tee sections, be spliced.

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

In the utility model, 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 wire physical dimension.

Accompanying drawing explanation

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

Reference numeral:

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

Embodiment

Below in conjunction with accompanying drawing and by embodiment, further illustrate the technical solution of the utility model:

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

With reference to Fig. 1, the utility model embodiment 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 Yi Gen center, and whole outside is coated 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, has reduced can produce gap between heart yearn and heart yearn, improves the compression degree of wire, reduces wire physical dimension.

The utility model embodiment provide the above; it is only preferably embodiment of the utility model; but protection range of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; according to the technical solution of the utility model and utility model design thereof, be equal to replacement or changed, within all should being encompassed in protection range of the present utility model.

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 Yi Gen center, and whole outside is coated 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 after the splicing of described inner wire, form circular cross-section, by the heart yearn of a plurality of watts of tee sections, be spliced.
