CN202384026U - Circular cable provided with powder filling layer - Google Patents

Abstract

The utility model provides a circular cable provided with a powder filling layer. The circular cable includes a plurality of cable cores which are formed by covering conductors with insulating layers. The cable cores are embedded into an outer sheath via a squeezing technology. A power is filled between the insulating layers and the cable cores. The circular cable has the basic transmission function of the cable, and can maintain the roundness and the integrity, save the raw material and the raw material cost. Besides, the cable cores can not adhere to the outer sheath.

Description

A kind of round cable with the powder packed layer

Technical field

The utility model relates to the electric wire field, particularly a kind of round cable with the powder packed layer.

Background technology

In the prior art, round cable is made up of the many groups of cable cores that are placed in the oversheath, and cable core comprises the insulating barrier composition of conductor and coating conductor; It is circular mostly cable core is, because the existence of the circular cable core of many groups, is between the many groups of circular cable cores in the oversheath and has the slit; Extruding between itself and the oversheath; Can influence round cable and keep rounding on the whole, can influence the serviceability of round cable, have two kinds of solutions in the prior art with this:

One of which, between cable core and oversheath, add packing material.This method makes round cable keep rounding on the whole through filling unnecessary gap between cable core and the oversheath; The problem of its existence is:

Owing to need to add extra material, can improve the input cost of cable, and increase the whole deadweight of round cable, need to improve.

Two, another kind is to adopt squash type technology, and cable core is embedded in the cable cover(ing).This method is filled up the gap between cable core and the oversheath through the oversheath body.The problem of its existence is:

This method can make the quality of oversheath increase, and increases the whole quality of round cable, causes the round cable cost to increase, and simultaneously, in adopting the squash type technical process, can cause taking place between oversheath and the cable core bonding, causes the whole cable degradation.

Based on above description, two kinds of methods that make round cable become rounding all need to improve in the prior art.

The utility model content

Utility model provides a kind of can keep rounding, save raw material, economize in raw materials the round cable of bonding band powder packed layer can not take place between cost and cable core and the oversheath.

The utility model solves the problems of the technologies described above through following technical scheme; A kind of round cable with the powder packed layer is proposed; Comprise many groups by the cable core that the insulating barrier coating conductor forms, organize said cable core more through squash type technology embedding oversheath, filling powder between insulating barrier and the said cable core.

Based on disclosing of above technical scheme, the utility model has possessed the cable basic functions.Further, the utility model adopts squash type technology to embed oversheath, before cable core is embedded oversheath; On cable core, evenly apply one deck powder and make powder embed into cable core; The entering of powder at first can occupy a part of space between cable core and the oversheath, because powder quality is light partially, makes that the use amount of raw material is on the low side; Thereby reduced cost of material; Further can make round cable keep rounding by the moulding process between sheath and the cable core because the existence of powder, also make can not take place between cable core and the oversheath bonding.

Based on open technique scheme, the utlity model has following beneficial effect:

The utlity model has the basic transfer function of cable.And can keep rounding, save raw material, can not take place between the cost that economizes in raw materials, cable core and the oversheath bonding.

Description of drawings

Below in conjunction with accompanying drawing the utility model is done further explanation:

Fig. 1 is the cross-sectional view of the utility model;

Among the figure:

1, conductor; 2, insulating barrier; 3, powder; 4, oversheath.

Embodiment

Embodiment 1

In conjunction with Fig. 1, present embodiment proposes a kind of round cable with the powder packed layer, comprises many groups by the cable core that insulating barrier 2 coating conductors 1 form, and organizes said cable core through squash type technology embedding oversheath 4, filling powder 3 between insulating barrier 2 and the said cable core more.

The utility model is not limited thereto execution mode, and the related realization assembly that is the basis with the utility model thought is all in the protection range of the utility model.

Claims (1)

1. the round cable with the powder packed layer comprises many groups by the cable core that insulating barrier (2) coating conductor (1) forms, and organizes said cable core through squash type technology embedding oversheath (4) more, it is characterized in that: filling powder (3) between insulating barrier (2) and the said cable core.
