Abstract
Electrical connector carbon fiber, carbon fiber involved with the hotline and the metal wires connecting joints technical fields. Carbon fiber beam exposed to carbon fiber insulation layer, the metal conductor one end exposed insulation layer metal, exposed to carbon fiber insulation layer of the carbon fiber beam with the bare metal in the insulation layer of metal conductor lap, at least one metal filament winding overlap each other in the carbon fiber beam and metal conductor on the side of winding wires of carbon fiber insulation extended to the end of the peripheral layer, metal wire and welded into a metal conductor overall; exposed carbon fiber beam above one end of the carbon fiber insulation layer one end and the exposed metal conductor insulation layer metal pyrocondensation installed in the same casing, the carbon fiber insulation layer and metal layer and the thermal insulation between the casing installed with hot melt adhesive. This invention achieved a simple structure, the use of effective, high safety factor of the purpose.
Description
Technical field
The present invention relates to the technical field of jointing between carbon fiber heating line and the plain conductor.
Background technology
All can use carbon fiber heating line in a lot of occasions in the daily life, such as using in people winter used electric blanket, but carbon fiber heating line itself has very big resistivity, so joint location at carbon fiber heating line and plain conductor, when simply connecting, cause the excessive phenomenon of contact resistance easily by conventional method.According to the electrotechnics principle, the contact resistance of joint is big more, and then the reliability of joint is low more.In addition,, generally use the insulation of ordinary hot Heat-Shrinkable Tubings or adopt adhesive plaster to twine, can not well play effects such as waterproof, protection against the tide, be easy to generate the accident of electric leakage in the joint location of carbon fiber heating line and plain conductor.
Summary of the invention
The object of the invention provides a kind of simple in structure, result of use good, coefficient of safety is high carbon fiber electric joint.
The present invention includes carbon fiber heating line and plain conductor, carbon fiber heating line comprises carbon fibre tow and carbon fiber insulating barrier, plain conductor comprises metallic conductor and metal dielectric layer, one end of carbon fibre tow exposes outside the carbon fiber insulating barrier, one end of metallic conductor exposes outside metal dielectric layer, expose carbon fibre tow and the metallic conductor overlap joint that exposes outside metal dielectric layer outside the carbon fiber insulating barrier, at least one one metal wire is wrapped on the carbon fibre tow and metallic conductor of mutual overlap joint, a side wiry is twined and is extended to carbon fiber insulating barrier end periphery, and wire and metallic conductor are welded into an integral body; The metal dielectric layer of the carbon fiber insulating barrier of above-mentioned exposed carbon fibre tow one end and bare metal conductor one end is arranged in the same heat-shrinkable T bush, is provided with hot melt adhesive between carbon fiber insulating barrier and metal dielectric layer and the heat-shrinkable T bush.
In the process of making, the insulating barrier of carbon fiber heating line and plain conductor blank area is peelled off respectively, with one or one group of wire carbon fibre tow and metallic conductor exposed, mutual overlap joint are intertwined, wire integral solder after the winding, can reduce the contact resistance of joint area between whole carbon fiber heating line and the plain conductor, thereby improve its reliability.Wire is wrapped on the carbon fibre tow and metallic conductor of mutual overlap joint, a side wiry is twined and is extended to carbon fiber insulating barrier end periphery, wire and metallic conductor are welded into an integral body, can reduce the contact resistance of joint area between whole carbon fiber heating line and the plain conductor, thereby improve its reliability, a side wiry extends to the outside, carbon fiber insulating barrier end simultaneously, strengthened the mechanical support intensity of the carbon fibre tow that exposes outside the carbon fiber insulating barrier, prevented that in use carbon fibre tow fractures.Exposed carbon fibre tow and metallic conductor are nested with in heat-shrinkable T bush, corresponding carbon fiber insulating barrier and metal dielectric layer are overlapped with heat-shrinkable T bush respectively, the inwall of heat-shrinkable T bush is provided with hot melt adhesive, behind overbaking, become insulating barrier with two wire rod water-tight, play waterproof, dampproof effect, strengthen fail safe in use.Purpose simple in structure, that result of use good, coefficient of safety is high that the present invention has realized.
The present invention is set in wire in the carbon fibre tow that overlaps with metallic conductor.In the use,, can play the effect of further reduction contact resistance because wire is passed from carbon fiber wire is intrafascicular.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
As shown in the figure, carbon fiber heating line 3 comprises carbon fibre tow 3-2 and carbon fiber insulating barrier 3-1, plain conductor 4 comprises metallic conductor 4-2 and metal dielectric layer 4-1, the end of carbon fibre tow 3-2 exposes outside carbon fiber insulating barrier 3-1, the end of metallic conductor 4-2 exposes outside metal dielectric layer 4-1, expose carbon fibre tow 3-2 and the metallic conductor 4-2 overlap joint that exposes outside metal dielectric layer 4-1 outside carbon fiber insulating barrier 3-1, wire 5 is wrapped on the carbon fibre tow 3-2 and metallic conductor 4-2 of mutual overlap joint, one side of wire 5 is twined and is extended to carbon fiber insulating barrier 3-1 end periphery, wire 5 and metallic conductor 4-2 welding; The metal dielectric layer 4-1 of the carbon fiber insulating barrier 3-1 of above-mentioned exposed carbon fibre tow 3-2 one end and bare metal conductor 4-2 one end is separately positioned in the heat-shrinkable T bush 1, and the inwall of heat-shrinkable T bush 1 is provided with hot melt adhesive 2.
Wire 5 is set in the carbon fibre tow 3-2 that overlaps with metallic conductor 4-2.This wire can be that thin copper wire also can be silver-gilt copper wire or tinned copper wire etc.
