Description
Technical Field
The utility model relates to a copper aluminium transition binding post.
Background
The copper-aluminum transition terminal is a wiring terminal product for connecting an aluminum wire to a copper end of equipment on a power transmission and distribution line. At present, a copper-aluminum transition terminal comprises a copper end and an aluminum wiring end, wherein the copper end and the aluminum wiring end are used for welding a copper bar and an aluminum bar together through friction welding and are manufactured through stamping and machining.
However, the structures of the copper-aluminum transition terminals are connected together in a friction welding manner, which easily causes unstable welding process during welding, thus resulting in high rejection rate of the copper-aluminum transition terminals, and the copper-aluminum welding parts are easy to break during installation and use, thus causing line faults; moreover, friction welding consumes a long time, and meanwhile, a lot of burrs are welded, machining process is complex, and efficiency is low; in addition, the technology that needs in the installation use is higher, because the aluminium end is bare to leak outward, improper installation causes the aluminium end directly to contact with equipment copper end easily, takes place circuit fault.
SUMMERY OF THE UTILITY MODEL
The main object of the utility model is to overcome the disadvantages of the prior art, and to provide a copper-aluminum transition terminal which has simple process, convenient manufacture, high yield and easy installation.
In order to realize the above-mentioned purpose, the utility model provides a copper aluminium transition terminal, including copper aluminium crimping piece and the copper aluminium wiring end of being connected with copper aluminium crimping piece, copper aluminium crimping piece is flattened jointly by an aluminium bar and the one end that fuses the cladding at the copper clad layer outside this aluminium bar and forms, has seted up the mounting hole on the copper aluminium crimping piece, copper aluminium wiring end system by aluminium bar and the cladding copper clad layer outside this aluminium bar fuse and form, wherein the free end orientation of copper aluminium wiring end copper aluminium crimping piece direction punches a hole and is formed with the wiring hole.
As above, the utility model discloses copper aluminium transition terminal includes copper aluminium crimping piece and copper aluminium wiring end, and copper aluminium crimping piece is flattened jointly by an aluminium bar and the one end that fuses the copper clad layer outside this aluminium bar and forms, and copper aluminium wiring end is fused the formation by aluminium bar and cladding copper clad layer outside this aluminium bar, and the copper aluminium transition terminal of this kind of structure is simple process not only, preparation convenience, yield height, easy installation use moreover.

Detailed Description
The embodiments of the present invention will be described in detail below. It should be emphasized that the following description is merely exemplary in nature and is not intended to limit the scope of the invention or its application.
Referring to fig. 1 and 2, the copper-aluminum transition terminal of the present invention includes a copper-aluminum crimping piece 10 and a copper-aluminum terminal 20 connected to the copper-aluminum crimping piece 10.
Referring to fig. 3 and 4, the copper-aluminum crimping piece 10 is flat and is formed by flattening an aluminum rod a and one end of a copper cladding layer b fused and coated outside the aluminum rod a together, and the copper-aluminum crimping piece 10 is provided with a mounting hole 11, and the mounting hole 11 is used for mounting and connecting with a copper connecting end of equipment.
The copper-aluminum terminal 20 is formed by fusing the aluminum rod a and a copper cladding layer b cladding the aluminum rod a, wherein a free end of the copper-aluminum terminal 20 is punched towards the copper-aluminum crimping piece 10 to form a wiring hole 21, and the wiring hole 21 is used for containing and connecting a wire core of a wire cable.
To sum up, the utility model discloses copper aluminium transition terminal includes copper aluminium crimping piece 10 and copper aluminium wiring end 20, and copper aluminium crimping piece 10 is flattened jointly by an aluminium bar an and the one end that fuses cladding copper clad layer b outside this aluminium bar an and forms, and copper aluminium wiring end 20 is fused by aluminium bar an and cladding copper clad layer b outside this aluminium bar an and forms, and the copper aluminium transition terminal of this kind of structure is simple in process not only, the preparation is convenient, the yield is high, installs easily moreover and uses.
The foregoing is a more detailed description of the present invention, taken in conjunction with the specific/preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. For those skilled in the art to which the invention pertains, a plurality of alternatives or modifications can be made to the described embodiments without departing from the concept of the invention, and these alternatives or modifications should be considered as belonging to the protection scope of the invention.
