Abstract
The utility model discloses an anti-bending and anti-stretching multipurpose braided cable, which comprises a cable core, a braided layer and an insulation layer. The cable core is in the form of a bundle of conductive metal wires. The braided layer is in the form of a tightly braided layer and is configured to closely surround the cable core. The tightly braided layer is formed through braiding conductive metal wires around the cable core. The insulation layer is made of rubber and plastic materials. A single layer of conductive metal wires are intertwined and overlapped to form the tightly braided layer. The tightly braided layer is composed of a hollowly intertwined part and a projectedly overlapped part. Each strand of the conductive metal wires of the tightly braided layer covers the other two strands of the conductive metal wires and is covered by the next two strands of the conductive metal wires at the same time. The insulation layer is in the form of an extruded insulation layer tightly coupled to the hollowly intertwined part and the projectedly overlapped part of the tightly braided layer. According to the technical scheme of the utility model, the insulation layer of the cable core is formed through the injection molding process, while the insulation layer and the cable core are intertwined and closely combined together at the same time. Therefore, the insulation layer and the cable core are mutually engaged with each other. In the mutual engagement state, the cable core is much less likely to deform, scatter and break off.
Description
Technical field
The utility model relates to a kind of essential electronic element of electricity field, specifically a kind of cable.
Background technology
Big machinery develops rapidly, and matched cable often needs mobile, bears larger more number of times pulling force and bending, and traditional flexible cable is used i.e. bending about half a year and various fracture defects conventionally, and impact is used.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of resistance to cable of subduing, and can bear and bear larger more number of times pulling force and bending, and be difficult for occurring the faults such as wire fracture.
For solving the problems of the technologies described above, warping strength, stretch-proof Multi-purpose knitting cable of the present utility model, comprise core, braid, insulating barrier, core is a branch of conductive wire, braid is tight braid, and closely braid closely surrounds core, closely braid itself is also formed by the braiding of conducting metal filament winding heart yearn, and described insulating barrier is rubber and plastic.
As the further improvement to the technical program, described tight braid is interlaced by individual layer conductive wire, be formed by stacking, and closely braid comprises the staggered portion of depression, protrudes stack portion.
As the further improvement to the technical program, 4 described of conductive wires are one above.
As the further improvement to the technical program, the conductive wire that every one conductive wire of described tight braid all covers after other conductive wires of two strands again by lower two strands covers.
As the further improvement to the technical program, described insulating barrier and the tight staggered portion of braid depression, protrude the insulating barrier of extruding that stack portion combines closely.Extruding insulating barrier is to utilize injection molding machine extruding and hot melting rubber to be enclosed in cable periphery, forms rubber insulation.
The anti-method of subduing of traditional increase cable is mainly to realize as reinforcement or by increasing soft and fine tension steel wire by the non-woven fabrics fiber of the integument in cable.
Above-mentioned way can change to a certain extent cable tension and warping strengthly have certain effect, but effect is still undesirable.Reason is that the cable of main equipment in use moves, the frequency crooked, that stretch is higher.The two non-tight parcel of the core layer of fibrage and conduction; The wire of conduction easily scatter in mobile BENDING PROCESS; Scattered wire is compared with the wire of tight bunchy, frangibility when occuring bending and deformation.
Equally also there are the problems referred to above in soft and fine tension steel wire.
In cable of the prior art, also have twisted wire cable, compare the single cord of same sectional area, twisted wire has higher mechanicalness pliability.But be also a kind of relative loose structure between the wire harness of twisted wire and wire harness.
Cable of the present utility model, the mentality of designing of breakthrough traditional cable, adopts core to add the mode of tight braid, and core is conductive wire with tight braid, and core is a branch of conductive wire; And closely braid is formed around core braiding by strands of metal wire; For preventing rupturing in braiding process, by adopting 4 of conductive wires, be one above.
Compare with traditional cable; In the following aspects, there is obvious superior function in the braid of the technical program:
First: conduct electricity the existence of tight braid, the tight braiding structure of itself has huge lifting to the ability of the stretch-proof of wire and anti-ability of subduing on the one hand.
Second: the conductor wire core of the cable of the technical program is that the tight braid of conduction closely wraps up equally; Conductor wire core is conducted electricity tight braid and is fettered into a branch ofly closely, is out of shape at random in the process that the line of core is difficult to bend at cable.Increased wire resistance to ability of subduing during flexural deformation in moving process.
The the 3rd: the tight braid of conduction of the technical program is owing to adopting the closely mode of braiding, when establishment, there will be that conductive wire is interlaced, the situation of stack, by and at tight braid, just formed and comprise the staggered portion of depression, protrude stack portion.Above-mentioned two interlaced distributions of part; When carrying out the insulating barrier of expressing technique formation core, insulating barrier and core can produce staggered combining closely; Insulating barrier and core are " interlock " mutually state.Under this state, the core possibility at random, that wreck that deforms reduces greatly.
The the 4th: this programme compares with the wire that increases metallic tensile wires the weight that has also effectively reduced wire.
Apply the five-core cable line that braid is made, in five heart yearns, zero line and earth connection adopt braid, are to take the axial symmetry that the radius of a circle of cable is symmetry axis and distribute in five heart yearns.If the core of cable adopts braid entirely, can increase the cost of line; Zero line in five heart yearns and earth connection are adopted to braid, in five heart yearns, be and take the axial symmetry that the radius of a circle of cable is symmetry axis and distribute, in cable, adding 2 lines is litzendraht wire, can effectively solve the technical problem of cable tensile strain easy fracture and crooked frangibility.
