Abstract

The utility model discloses an improvement on a conductor structure for producing flexible cables and relates to a multi-fine copper wire concentric bundle twisted conductor structure for producing the flexible cables. The multi-fine copper wire concentric bundle twisted conductor structure is characterized in that a cross section of a bundle twisted conductor comprises a central layer and a peripheral layer by threading in layers, so that the traditional aspheric bundle twisted conductor is changed into a round bundle twisted conductor. By using the multi-fine copper wire concentric bundle twisted conductor structure, the thickness of an insulating layer is uniform, the insulating quality and level of the cable are improved, the size of the cable is reduced and a large amount of insulating materials and jacket materials can be saved; and the multi-fine copper wire concentric bundle twisted conductor structure has remarkable economic benefit and is favored by users.

Description

A kind of many thin copper wires are restrainted the strand conductor structure with one heart

Technical field

The utility model is to producing the improvement of flexible cable with conductor structure, relating to a kind of production flexible cable and restraint the strand conductor structure with one heart with many thin copper wires.

Background technology

At present, domestic production flexible cable conductor generally adopts one to form the bundle formula is stranded by 0.30mm and following thin copper.Because traditional bundle formula is stranded, make finished product conductors cross out-of-shape, rounding not, has very big randomness, this irregular structure shape causes conductor overall dimension big, in order to ensure the book dot thickness that insulate, have to strengthen the insulation outside dimension, cause consequences such as waste of insulating material and sheath material and outside diameter of cable size are big.

Summary of the invention

The purpose of this utility model is for overcoming the defective of above-mentioned existence, providing a kind of many thin copper wires to restraint the strand conductor structure with one heart.

Many thin copper wires of the utility model are restrainted strand conductor structure content Description with one heart:

Many thin copper wires of the utility model are restrainted the strand conductor structure with one heart, it is characterized in that: adopt layering threading bundle strand, conductors cross is made of central core and peripheral layer, the central core and the rounded structure of peripheral layer of bundle strand conductors cross.

Many thin copper wires of the utility model are restrainted the strand conductor structure with one heart, make thickness of insulating layer evenly, cable insulation quality level is improved, cable dimension descends, save a large amount of insulating material and sheath material, has obvious economic benefit, and be subjected to the user and welcome.

Among the figure: the 1st, central core, the 2nd, peripheral layer.

Embodiment

Many thin copper wires of the utility model are restrainted the strand conductor structure with one heart and are achieved in that to do below in conjunction with accompanying drawing and specify.See Fig. 1, many thin copper wires are restrainted the strand conductor structure with one heart, adopt layering threading bundle strand conductors cross to be made of the central core 1 and the peripheral layer 2 rounded structures of bundle strand conductors cross central core 1 and peripheral layer 2.

Adopt the utility model to change in the past traditional not stratified one, make bundle twist conductors cross and become circular configuration the harness threading method.

Adopt the layering threading method, the total radical of thin copper wire of central core 1 and peripheral layer 2 sees Table 1.

Many thin copper wires of the utility model restraint the strand conductor structure with one heart, changed conductor by original irregularly shaped become circular configuration after, make thickness of insulating layer even, cable insulation quality level is improved.After conductor became circular configuration, cable dimension descended, and saves a large amount of insulating material and sheath material, has obvious economic benefit, and was subjected to user's welcome.

Claims

1. many thin copper wires are restrainted the strand conductor structure with one heart, it is characterized in that: bundle strand conductors cross is made of central core (1) and peripheral layer (2), the central core (1) and the rounded structure of peripheral layer (2) of bundle strand conductors cross.
