Abstract
The present invention discloses a copper-aluminum crimping terminal of an embedded liner tube. The copper-aluminum crimping terminal of the embedded liner tube comprises a flat pure copper crimping terminal of which one end is equipped with a wiring hole, and the other end is equipped with a copper tube integrally. A pure aluminum liner tube is arranged in an inner cavity of the copper tube coaxially, the copper tube is in interference fit with the pure aluminum liner tube, and the internal diameter of the pure aluminum liner tube matches the wire diameter of a crimped conducting wire. One end of the pure aluminum liner tube is opened to insert the conducting wire, and the other end is enclosed and is arc-shaped. The copper-aluminum crimping terminal of the embedded liner tube of the present invention is mainly used at the transition connection position of the copper-aluminum conducting wires in the electric power lines and the electrical devices, and enables the phenomenon that the original copper-aluminum crimping terminal is overheated and burnt out due to the own structure defect to be improved effectively.
Description
Technical field:
The present invention relates to a kind of copper aluminium crimp type terminal of embedded bushing pipe.
Background technology:
At present, between power circuit or electric equipment, connect transition and conventionally adopt binding post machinery crimping method.
One, traditional copper aluminium crimp type terminal material is single, simple in structure, and operating personnel only has between crimping point place's wire and binding post contact gear ratio tightr in crimping process, and copper aluminum connecting terminal and wire contact area are little.
Two, the coefficient of expansion of aluminium and copper differs larger, energising repeatedly heat up and power-off cooling after, make joint loosening and occur space, when air or moisture enter, cause the oxidized or corrosion in aluminum steel surface, make contact resistance increase.
Three, the chemism difference of copper and aluminium will form local cell effect after junction enters tide (wetting) gas, and aluminium conductor is corroded, and cause contact condition to worsen.
Summary of the invention:
For overcoming the defect of prior art, the object of the present invention is to provide a kind of copper aluminium crimp type terminal of embedded bushing pipe, for power circuit and electric equipment, need the transition of copper aluminum conductor to connect part.
Technical solution problem of the present invention adopts following technical scheme:
A kind of copper aluminium crimp type terminal of embedded bushing pipe, the fine copper matter crimp type terminal that comprises flat body structure, one end of described fine copper matter crimp type terminal is provided with wiring hole, other end integral type at fine copper matter crimp type terminal is provided with copper pipe, at described copper pipe inner chamber, be coaxially provided with fine aluminium matter bushing pipe, described copper pipe and described fine aluminium matter bushing pipe interference assembling, the internal diameter of fine aluminium matter bushing pipe be crimped wire diameter and match; One end opening of described fine aluminium matter bushing pipe to be to insert wire, and the other end seals and is circular arc.
The openend of described fine aluminium matter bushing pipe is concordant with the oral area of described copper pipe, and crimping modulus and the spacing of the length of fine aluminium matter bushing pipe and wire regulation match.
The wall thickness of described fine aluminium matter bushing pipe and copper pipe is not less than 2mm, the intensity while guaranteeing crimping.
A kind of copper aluminium crimp type terminal of embedded bushing pipe, the fine aluminium matter crimp type terminal that comprises flat body structure, one end of described fine aluminium matter crimp type terminal is provided with wiring hole, other end integral type at fine aluminium matter crimp type terminal is provided with aluminum pipe, at described aluminum pipe inner chamber, be coaxially provided with fine copper matter bushing pipe, described aluminum pipe and described fine copper matter bushing pipe interference assembling, the internal diameter of fine copper matter bushing pipe be crimped wire diameter and match; One end opening of described fine copper matter bushing pipe to be to insert wire, and the other end seals and is circular arc.
The openend of described fine copper matter bushing pipe is concordant with the oral area of described aluminum pipe, and crimping modulus and the spacing of the length of fine copper matter bushing pipe and wire regulation match.
The wall thickness of described fine copper matter bushing pipe and aluminum pipe is not less than 2mm.
Compared with the prior art, beneficial effect of the present invention is embodied in:
Problem to be solved by this invention is, traditional copper aluminum connecting terminal and wire contact area are too little, and because the copper aluminium coefficient of expansion is different, after repeatedly switch on intensification and power-off are cooling, being prone to joint becomes flexible and produces cavitation, when air or moisture enter, cause the oxidized or corrosion in aluminum steel surface, contact resistance is increased and then the overheated phenomenon of blowing in joint occurs.In order to solve the problems of the technologies described above, the copper aluminium crimp type terminal of the embedded bushing pipe the invention provides, needs the transition of copper aluminum conductor to connect part for power circuit and electric equipment.There is the bushing pipe of inlaying described copper aluminium crimp type terminal inside, and the two mode by cold extrusion interference fit is carried out combination assembling, guarantees that between copper aluminium, combination is closely seamless, effectively prevents from causing oxidation after moisture and air from entering both faying faces.By add internal lining pipe again with conductor compression jointing, can increase the contact area of copper aluminium junction, reduced the space outside crimping point, effectively reduce the contact resistance between copper aluminium, prevented that terminal place is because of overheated generation of blowing accident.Embedded bushing pipe has certain thickness, and consistent be crimped lead material, and the contact area of aluminium hydraulic pressed connecting pipe and wire in the time of can effectively increasing crimping reduces contact resistance, has prevented that terminal place is because of overheated generation of blowing accident.
