Description
Technical field:
The utility model relates to a kind of copper aluminium crimp type terminal of embedded bushing pipe.
Background technology:
At present, connect transition between power circuit or electric equipment and usually adopt binding post machinery by crimping.
One, traditional copper aluminium crimp type terminal material is single, structure is simple, and operating personnel only has contact gear ratio between crimping point place's wire and binding post comparatively tight in crimping process, copper aluminum connecting terminal and conductive contact area little.
Two, the coefficient of expansion difference of aluminium and copper is comparatively large, heats up and after power-off cooling, makes joint loosen and occur space being repeatedly energized, and when air or moisture enter, causes aluminum steel surface oxidized or corrode, contact resistance is increased.
Three, the chemism difference of copper and aluminium, will form local cell effect, aluminium conductor is corroded, and cause contact condition to worsen after junction enters tide (wetting) gas.
Summary of the invention:
For overcoming the defect of prior art, the purpose of this utility model is the copper aluminium crimp type terminal providing a kind of embedded bushing pipe, connects part for needing the transition of copper aluminum conductor in power circuit and electric equipment.
The utility model technical solution problem adopts following technical scheme:
A kind of copper aluminium crimp type terminal of embedded bushing pipe, comprise the fine copper matter crimp type terminal of flat body structure, one end of described fine copper matter crimp type terminal is provided with wiring hole, copper pipe is provided with in the other end integral type of fine copper matter crimp type terminal, fine aluminium matter bushing pipe is provided with at described copper pipe coaxial, described copper pipe and described fine aluminium matter bushing pipe elastic conjunction, the internal diameter of fine aluminium matter bushing pipe be crimped wire diameter and match; The one end open of described fine aluminium matter bushing pipe is to insert wire, and the other end is closed and is circular arc.
The openend of described fine aluminium matter bushing pipe is concordant with the oral area of described copper pipe, and the length of fine aluminium matter bushing pipe and wire specify crimp modulus and spacing matches.
The wall thickness of described fine aluminium matter bushing pipe and copper pipe is not less than 2mm, ensures intensity during crimping.
A kind of copper aluminium crimp type terminal of embedded bushing pipe, comprise the fine aluminium matter crimp type terminal of flat body structure, one end of described fine aluminium matter crimp type terminal is provided with wiring hole, aluminum pipe is provided with in the other end integral type of fine aluminium matter crimp type terminal, fine copper matter bushing pipe is provided with at described aluminum pipe coaxial, described aluminum pipe and described fine copper matter bushing pipe elastic conjunction, the internal diameter of fine copper matter bushing pipe be crimped wire diameter and match; The one end open of described fine copper matter bushing pipe is to insert wire, and the other end is closed and is circular arc.
The openend of described fine copper matter bushing pipe is concordant with the oral area of described aluminum pipe, and the length of fine copper matter bushing pipe and wire specify crimp modulus and spacing matches.
The wall thickness of described fine copper matter bushing pipe and aluminum pipe is not less than 2mm.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
Problem to be solved by this invention is, traditional copper aluminum connecting terminal and conductive contact area too little, and because the copper aluminium coefficient of expansion is different, after be repeatedly energized intensification and power-off cooling, easily occur that joint loosens and produces cavitation, when air or moisture enter, cause the oxidized or corrosion in aluminum steel surface, contact resistance is increased and then occurs that joint is overheated blows phenomenon.In order to solve the problems of the technologies described above, the copper aluminium crimp type terminal of the embedded bushing pipe that the invention provides, connects part for needing the transition of copper aluminum conductor in power circuit and electric equipment.Described copper aluminium crimp type terminal inside has inlays bushing pipe, and the two mode by cold extrusion interference fit carries out combination assembling, in conjunction with closed seamless gap between guarantee copper aluminium, causes oxidation after effectively preventing moisture and air from entering both faying faces.By add internal lining pipe again with conductor compression jointing, the contact area of copper aluminium junction can be increased, decrease crimping point outside space, effectively reduce the contact resistance between copper aluminium, prevent terminal place to blow the generation of accident because of overheated.Embedded bushing pipe has certain thickness, and consistent be crimped lead material, and the contact area of aluminium hydraulic pressed connecting pipe and wire when effectively can increase crimping, reduces contact resistance, prevent terminal place to blow the generation of accident because of overheated.
