Compared with the prior art, the method has the following positive effects: has the characteristics of heat resistance, scratch and abrasion resistance, acid and alkali resistance, environmental protection and flame retardance.
Description
Technical Field
The utility model relates to a cable, concretely relates to for military use special type is drawn and is connect cable for motor.
Background
The motor is widely applied as a power driving source and occupies an increasingly important position in economic development of various countries in the world, and the industry plays an important role in flying to draw economic development of a plurality of industrial countries.
According to the planning statistics of the industry, the motor serving as the most main power source of industrial equipment has huge machine loading amount and wide demand market, the market scale of the motor manufacturing industry in China is expected to exceed 5000 million yuan by 2018, and the annual composite growth rate exceeds 20%.
The motor leading cable connects the winding out to the junction box, bears all current and all voltage of the motor and electric appliance and can adapt to high temperature and high heat environment in the motor. A plurality of manufacturers in China can produce the motor lead cable, but the performance of the lead cable is not ideal, and the phenomena of breakdown, heating and burning of the whole motor caused by heating damage and poor contact of the lead cable occur sometimes, so that the manufacturability of the motor final assembly and the reliability in actual operation are seriously influenced. The high-frequency permanent magnet motor leading cable for military special vehicles has higher requirements.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing one kind for market, can satisfy rated voltage AC1000V, heat-resisting, wear-resisting, acid and alkali-resistance, environmental protection, shielding type silicon rubber insulating silicon rubber sheath military special type motor draws and connects the cable product.
In order to achieve the above object, the utility model provides a technical problem adopt following technical scheme:
a lead cable for military special motor is prepared as twisting several soft copper wires and copper foil wire into soft conductor by a certain pitch, extruding silicon rubber material to form insulation layer outside soft conductor, weaving tinned soft copper wire outside insulation layer to form woven shield layer, extruding silicon rubber material to form inner protection layer outside woven shield layer, weaving glass fiber and impregnating liquid silicon resin to form outer protection layer outside inner protection layer.
The copper foil wire is a conductor formed by one or more twisted elements, and each element is formed by spirally lapping one or more thin metal strips on a fiber wire and supporting the fiber wire.
The annealed copper wires and the copper foil wires are in a same-direction twisting and untwisting structure.
The section of the soft conductor is that the copper foil wire is arranged at the inner side and the soft copper wire is arranged at the periphery.
The silicone resin is a thermosetting polysiloxane polymer with a highly cross-linked structure, has the dual characteristics of organic resin and inorganic materials, has unique physical and chemical properties, and has good electrical insulation property, temperature resistance and waterproof effects.
A for military use special type motor is with drawing cable, compare with prior art and have following positive effect: the product has the characteristics of heat resistance, scratch and abrasion resistance, acid and alkali resistance, environmental protection and flame retardance, and in consideration of the use occasions of the product, the copper foil wire conductor structure is added in the middle of the conductor part of the product, and the equidirectional twisting and untwisting technology is adopted, so that the tensile property of the conductor is enhanced, the electrical property of the conductor is ensured, and the external diameter of the conductor is reduced due to the equidirectional twisting technology, and the use of outer layer materials is saved; the insulating layer and the inner protective layer are made of flame-retardant impregnating varnish-resistant silicone rubber material, and the flexibility, high and low temperature resistance and impregnating varnish resistance of the product are guaranteed by extrusion; the shielding layer adopts a shielding structure woven by tinned copper wires, so that the problem of mutual interference of external magnetic fields inside the product is effectively solved; the outer protective layer adopts a structure that glass fiber is woven and impregnated with flame-retardant liquid silicone resin, so that the problems that silicone rubber is not scratch-resistant and easy to damage are solved, and the flame retardant property of the product is improved.

Detailed Description
As shown in fig. 1, the utility model discloses an embodiment, this kind of for military use special type motor is with drawing cable adopts a plurality of annealed copper wires 2 and copper tinsel 1 to strand into the flexible conductor through certain pitch, and the outer crowded package silicon rubber material of flexible conductor constitutes insulating layer 3, and 3 outside weaving tinned annealed copper wires of insulating layer constitute and weave shielding layer 4, weave shielding layer 4 and extrude package silicon rubber material outward and constitute inner sheath 5, and inner sheath 5 weaves glass fiber and soaks liquid silicone resin outward and constitutes outer jacket 6.
The copper foil wire 1 is a conductor formed by one or more twisted elements, and each element is formed by spirally lapping one or more thin metal strips on a fiber wire and supporting the fiber wire.
The annealed copper wires 2 and the copper foil wires 1 are in the same-direction twisting and untwisting structure.
The section of the soft conductor is that the copper foil wire 1 is arranged at the inner side and the soft copper wire 2 is arranged at the periphery.
The utility model discloses a copper foil wire 1 and annealed copper conductor 2 strand into the soft conductor through certain pitch, constitute insulating layer 3 through crowded package fire-retardant, resistant impregnating varnish silicon rubber insulating material in the soft conductor outside, then weave the tinned copper wire outside the insulation core and constitute and weave shielding layer 4, weave the shielding layer outside crowded package fire-retardant, resistant impregnating varnish silicon rubber as interior sheath 5, weave glass fiber and impregnating silicon resin as outer jacket 6 at last.
