Abstract
The utility model provides a carbon fiber electric joint, relating to the technical field of a connection joint between a carbon fiber heating wire and a metal lead. One end of a carbon fiber beam exposes out of a carbon fiber insulation layer, and one end of a metal conductor exposes out of a metal insulation layer; the carbon fiber beam that exposes out of the carbon fiber insulation layer is lap-connected with the metal conductor that exposes out of the metal insulation layer; at least one metal wire is winded on the carbon fiber beam and the metal conductor which are lap-connected mutually; one side of the metal wire twists and extends to the periphery of the end of the carbon fiber insulation layer, the metal wire and the metal conductor are welded into a whole. Moreover, the carbon fiber insulation layer at the end of the exposed carbon fiber beam and the metal insulation layer at the end of the exposed metal conductor are arranged in a same pyrocondensation sleeve; and hot melt glue is positioned between the carbon fiber insulation layer and the pyrocondensation sleeve and between the metal insulation layer and the pyrocondensation sleeve. The utility model realizes the aims of simple structure, good using effect and high safety factor.
Description
Technical field
The utility model 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.
The utility model content
The utility model purpose provides a kind of simple in structure, result of use good, coefficient of safety is high carbon fiber electric joint.
The utility model comprises 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 utility model has been realized.
The utility model 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.
