Abstract
The utility model relates to a precision cable metal wire bonded by nano powder sintering, and the precision cable metal wire is wired by main wires, a gap wire, and nano powders, a cross section of the main wire is in a round shape, a cross section of the gap wire is in a round shape, a cross section area of the gap wire is one fiftieth to one hundredth of a cross section area of the main wire, the gap wire is positioned in a gap position among three adjacent main wires, the nano powders fill gaps between the gap wire and the main wires, and the nano powders tightly bond the gap wire with the main wires through sintering. Beneficial effects are that effective conduction area of metal wire wiring structure is effectively improved, resistance among wires is reduced, and compactibility of the metal wire wiring structure is improved.
Description
Technical field
The utility model relates to the cable technology field, relates to or rather a kind of accurate cable metal wire rod of nanometer powder sintered bonds.
Background technology
Cable with metal wire rod comprise copper cash or aluminum steel normally cross section be circular wire rod, the conductive cores of cable is exactly to be made by the metal wire rod spiral winding of many circles, squeezing action by mould, 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 three adjacent wire rods, because the space is non-conductive, like this in order to reach satisfactory effective conductive area, the actual cross-sectional area of the strand structure processed of metal wire rod tends to greater than effective conductive area, after the metal wire rod chap, the material usage of the outer jacket that the outside needs, armour and packed layer also increases thereupon, causes the cable chap, become heavy, and then the lifting cable cost, improve logistics cost, increased difficulty of construction.In addition, because metal wire rod strand structure processed is to be formed by the mould extruding, the stress that self has expanse, cause each money paid for shares to belong to the larger sheet resistance of existence between the wire rod, so that the part transmission current is not mobile along the axis direction of cable, but along each strand electric wire internal flow that is spiral strand state processed, the current delivery length of equivalence increases, and resistance dissipates and increases; Near the section that cable blocks, loose situation can occur in an end of the opening of metal wire rod strand structure processed under the effect of swelling stress simultaneously.
This shows, above-mentioned existing cable still has many defectives with metal wire rod strand structure processed, and demands urgently being improved.
Because the defective that above-mentioned existing cable exists with metal wire rod strand structure processed, 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 metal wire rod of nanometer powder sintered bonds, can improve the general on the market molding structure of existing cable metal wire rod, 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 wire rod strand structure processed, and provide a kind of cable metal wire rod of nanometer powder sintered bonds, overcome existing cable and had the space with metal wire rod, there is expansionary stress, resistance loss between each strand electric wire, and loose defective can occur at an open end improves cable with the tightness degree of metal wire rod strand structure processed.
The utility model solves its technical problem underlying and realizes by the following technical solutions.Accurate cable metal wire rod according to the nanometer powder sintered bonds that the utility model proposes, formed by electric main, space electric wire and nanometer powder strand system, the electric main cross section is rounded, the space wire cross-section is rounded, space wire cross-section area is one of 1/50th to one percentage of electric main cross-sectional area, the space electric wire is positioned at the position, space of adjacent three electric mains, nanometer powder is filled the space between space electric wire and the electric main, by sintering, nanometer powder is with space electric wire and electric main close adhesion.
The accurate cable metal wire rod of nanometer powder sintered bonds described in the utility model, the beneficial effect of its generation is: adopt the position, space of adjacent three electric mains of space wire pair to fill, effectively improved effective conductive area 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, space electric wire; 3, nanometer powder.
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, the accurate cable metal wire rod of nanometer powder sintered bonds of the present utility model, formed by electric main 1, space electric wire 2 and nanometer powder 3 strand systems, electric main 1 cross section is rounded, electric wire 2 cross sections in space are rounded, electric wire 2 cross-sectional areas in space are one of 1/50th to one percentages of electric main 1 cross-sectional area, space electric wire 2 is positioned at the position, space of adjacent three electric mains 1, the space that nanometer powder 3 is filled between space electric wire 2 and the electric main 1, by sintering, nanometer powder 3 is with space electric wire 2 and electric main 1 close adhesion.In metal wire rod strand process processed, corresponding deformation can occur in each strand electric wire, so that further reduce in the space between each strand material.
The above, it only is 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.
