Abstract
The utility model relates to a precision metal material used for a cable. The material is made of a plurality of wires through stranding. A cross section is in a tile shape. The metal material is characterized in that the metal material is made of main wires, edge gap wires and intermediate gap wires through stranding; the cross section of the each main wire is in a round shape; the cross section of the each intermediate gap wire is in the round shape; the intermediate gap wires are located at gap positions among the three adjacent main wires; the edge gap wires are in a triangle shape; the edge gap wires are located at the gap positions of the two adjacent marginal main wires. By using the metal material of the utility model, there are the following advantages that a tightness degree of the metal material is effectively increased so that conductive performance of the metal material used for the cable is increased; a smooth degree of the edge of a metal wire stranding structure is effectively increased.
Description
Technical field
The utility model relates to the cable technology field, relates to or rather a kind of cable precision metallic material.
Background technology
The cable metal material is to be that circular metal wire rod spiral winding is made by many sliver transvers sections, and by extrusion die, the multiply metal wire rod is extruded distortion, twists cross section processed and be the strand structure processed of the shapes such as fan-shaped, watt shape, circle.Circular metal wire rod strand is built in together, can there be the space in the middle of adjacent wire rod, because the space can cause the metal wire rod chap, the outer jacket that the outside needs and the material usage of armour also increase thereupon, cause cable to become heavy and chap, improve cable cost, improved logistics cost, increased difficulty of construction.On the other hand, can there be the space in the middle of adjacent wire rod, also can hinders electric current flowing between adjacent wire, weaken the electric conductivity of metal material.
At the edge of cable with metal material, the cross section of metal wire rod is rounded, and it is irregularly shaped that the edge will occur rising and falling, and in high-tension environment for use, the projection at edge easily causes point discharge, causes accident.
This shows, above-mentioned existing cable still has many defectives with metal material, and demands urgently being improved.
Because the defective that above-mentioned existing cable exists with metal material, the design people is based on being engaged in this type of product design manufacturing for many years, amassing has abundant practical experience and professional knowledge, positive research and innovation in addition, to founding a kind of cable precision metallic material, can improve general existing cable on the market with the molding structure of metal material, make it have more competitiveness.Through constantly research, design, and after repeatedly studying sample and improvement, finally create the utility model that has practical value.
Summary of the invention
Technical problem underlying to be solved in the utility model is, overcome the defective that existing cable exists with metal material, and provide a kind of cable precision metallic material, overcome existing cable and had the up-and-down defective in space and edge with metal material, improved tightness degree, electric conductivity and the smooth of the edge degree that cable is used metal material.
The utility model solves its technical problem underlying and realizes by the following technical solutions.According to the cable precision metallic material that the utility model proposes, formed by strand wire strand system, cross section is a watt shape, cable is comprised of electric main, edge voids electric wire and intermediate gaps electric wire strand system with the precision metallic material, the electric main cross section is rounded, and the intermediate gaps wire cross-section is rounded, and the intermediate gaps electric wire is positioned at the position, space of adjacent three electric mains, the edge voids electric wire is triangular in shape, and the edge voids electric wire is positioned at the position, space of the electric main of adjacent two edges edge.
Cable described in the utility model precision metallic material, the beneficial effect of its generation is: adopt the position, space of adjacent three electric mains of intermediate gaps wire pair to fill, effectively improved the tightness degree of metal material, and then improved cable with the electric conductivity of metal material, adopt the position, space of the electric main of the adjacent adjacent two edges edge of edge voids wire pair to fill, effectively improved the smooth of the edge degree of metal wire rod strand structure processed.
Description of drawings
Fig. 1 is the schematic cross-section of embodiment of the present utility model.
Description of reference numerals: 1, electric main; 2, intermediate gaps electric wire; 3, edge voids electric wire.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to its embodiment, structure, feature and the effect thereof that the utility model proposes, be described in detail as follows.
See also shown in Figure 1, cable of the present utility model precision metallic material, formed by strand wire strand system, cross section is a watt shape, cable is comprised of electric main 1, intermediate gaps electric wire 2 and edge voids electric wire 3 strand systems with the precision metallic material, electric main 1 cross section is rounded, intermediate gaps electric wire 2 cross sections are rounded, intermediate gaps electric wire 2 is positioned at the position, space of adjacent three electric mains 1, edge voids electric wire 3 is triangular in shape, and edge voids electric wire 3 is positioned at the position, space of the electric main 1 of adjacent two edges edge.In metal wire rod strand process processed, corresponding deformation can occur in each strand electric wire, makes the space between each strand material further reduce.
The above, it is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
