Abstract
The utility model relates to a twisting structure of metal wires for a cable. The twisting structure comprises an internal layer of wires and an external layer of wires, wherein the internal layer of wires comprises four strands of wires with sector-shaped cross sections, the outer layer of wires comprises multiple strands of wires capable of embedding each other, and cross sections of the embedded parts are in square shapes. According to the twisting structure of the utility model, the situation that one open ends of the metal wires near the section of the cables are loosened under the action of an expansion stress, thereby the tightness of the twisting structure of the metal wires is improved.
Description
Technical field
The utility model relates to the cable technology field, relates to a kind of cable or rather with metal wire rod strand system structure.
Background technology
Cable use metal wire rod comprise copper cash or aluminum steel normally cross section be the wire rod of circle; The conductive cores of cable is exactly to be processed by the metal wire rod spiral winding of many circles; Squeezing action through grinding tool; The multiply metal wire rod is extruded distortion, and strand system cross section is the strand system structure of shapes such as fan-shaped, watt shape, circle.Because metal wire rod strand system structure is to be formed by the mould extruding; The stress that self has expanse property; Cause each money paid for shares to belong to the bigger sheet resistance of existence between the wire rod; Near the section that cable blocks, loose situation can take place in an end of the opening of metal wire rod strand system structure under the effect of swelling stress simultaneously.
This shows that above-mentioned existing cable still has many defectives with metal wire rod strand system structure, and demands urgently improving.
Because the defective that above-mentioned existing cable exists with metal wire rod strand system structure; The design people is based on being engaged in this type of product design manufacturing for many years; Long-pending have abundant practical experience and professional knowledge, actively studies innovation, in the hope of founding a kind of cable that improves molding structure with metal wire rod strand system structure; Can improve the molding structure of general existing cable on the market, make it have more competitiveness with metal wire rod strand system structure.Through constantly research, design, and after studying sample and improvement repeatedly, found out the utility model of true tool practical value finally.
Summary of the invention
The utility model technical problem underlying to be solved is; Overcome the defective that existing cable exists with metal wire rod strand system structure; And provide a kind of cable of new structure to make structure with the metal wire rod strand; Overcome existing cable and had expansionary stress, and loose defective can take place, improved the tightness degree of cable with metal wire rod strand system structure at an open end with metal wire rod strand system structure.
The utility model solves its technical problem underlying and adopts following technical scheme to realize.Cable according to the utility model proposes is made structure with the metal wire rod strand, deck wire and outer deck wire in comprising, and outer deck wire comprises the wire rod that multiply can embed each other.
The utility model solves its technical problem and can also adopt following technical measures further to realize.
Before described in deck wire comprise that four strands of cross sections are fan-shaped wire rod.
Before the shape of cross section of embedded part of the described multiply wire rod that can embed each other be square.
The utility model compared with prior art has tangible advantage and beneficial effect.Can be known that by above technical scheme the utility model is owing to adopt technique scheme, interior deck wire is that fan-shaped wire rod will be formed by four strands of cross sections; Four strands of cross sections are fan-shaped wire rod owing in strand system process, do not have deformation; So do not have the stress of repulsion each other, outer deck wire is made up of the wire rod that multiply can embed each other, the shape of cross section of the part that embeds each other is square; Like this under the mutual packing interaction of mutual embedded part; Loose situation just can not take place in metal wire rod strand system structure, and it is also tightr that each money paid for shares belongs to the combination of wire rod, reaches the purpose of the utility model.
Above-mentioned explanation is merely the general introduction partly of the utility model technical scheme characteristic; For making the professional and technical personnel can more know the technological means of understanding the utility model; And can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.
The embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Fig. 1 is the profile of this practical cable with metal wire rod strand system structure.
Among the figure, interior deck wire 1, outer deck wire 2, embedded part 22.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to its embodiment, structure, characteristic and the effect thereof that proposes according to the utility model, specify as after.
See also shown in Figure 1; The cable of the utility model is with metal wire rod strand system structure; Deck wire 1 and outer deck wire 2 in comprising; Outer deck wire 2 comprises the wire rod that multiply can embed each other, and interior deck wire 1 comprises that four strands of cross sections are fan-shaped wire rod, and the shape of cross section of the embedded part 22 of the wire rod that multiply can embed each other is square.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
Claims (3)
1. cable is characterized in that with metal wire rod strand system structure, deck wire and outer deck wire in comprising, and outer deck wire comprises the wire rod that multiply can embed each other.
2. cable according to claim 1 is characterized in that with metal wire rod strand system structure wherein said interior deck wire comprises that four strands of cross sections are fan-shaped wire rod.
