Abstract

A crimping device of an aluminum electromagnetic wire and a copper conductor comprises an aluminum electromagnetic wire joint, a copper conductor joint and a crimping member. The crimping device of the aluminum electromagnetic wire and the copper conductor is characterized in that the crimping member is a long U-shape bar; nine protruding horizontal strips are arranged inside the long bar; both sides of the surface of each horizontal strip are provided with burrs higher than a plane; after being stamped, the aluminum electromagnetic wire joint and the copper conductor joint are wrapped in the crimping member; the burrs on the horizontal strips in the crimping member will pierce an insulation layer of the aluminum electromagnetic wire joint in stamping, such that the contact resistance of the crimping member and the aluminum electromagnetic wire joint is almost zero; and as a result, the connection of the aluminum electromagnetic wire and the copper conductor is completed. The crimping device of the aluminum electromagnetic wire and the copper conductor has the following advantages that: without removing the insulation layer of the aluminum electromagnetic wire joint in advance required, production processes can be reduced; and in stamping operation, only the aluminum electromagnetic wire joint and the copper conductor joint need to be placed in a crimping and molding mold so as to be stamped, such that the connection of the aluminum electromagnetic wire and the copper conductor can be completed, and therefore, production efficiency is very high.

Description

A kind of aluminium magnet wire and copper conductor compression bonding apparatus

Technical field

The utility model relates to the jockey of a kind of aluminium magnet wire and copper conductor.

Background technology

For copper conductor and aluminium magnet wire are linked together, at present the most general solution adds the scaling powder welding exactly, but this will relate to environmental protection and the problem such as corrosion-resistant; It is interconnection technique that employing " terminal is beaten button " is also arranged, and " crimp technology " of this American-European countries comparative maturity needs with more expensive safe section terminal, and only more applicable to the heavy caliber enamelled wire, so uneconomical applicable; Also have and adopt the sleeve pipe of colding pressing, be that aluminum steel inserts respectively a special copper sleeve when being connected from two with copper cash, and then with cord end plier, connector is flattened, make aluminum steel and copper cash complete connection, the shortcoming of this structure is that the insulating barrier of aluminium magnet wire is difficult for abolishing fully, causes contact resistance value unstable.

The utility model content

The purpose of this utility model is exactly in order to overcome above-mentioned weak point of the prior art, provide a kind of simple and reasonable, cost of manufacture is low, production process is few, decay resistance and the good aluminium magnet wire of processing performance and the compression bonding apparatus of copper conductor.

The utility model solves the problems of the technologies described above adopted technical scheme: the compression bonding apparatus of a kind of aluminium magnet wire and copper conductor, comprise the aluminium magnet wire joint, copper wire lead and crimp, it is characterized in that: described crimp is the rectangular of a U word shape, the horizontal stripe that nine projections are arranged in described crimp rectangular, described horizontal stripe is uniformly distributed, there is the burr of high out-of-plane on both sides on the horizontal stripe face, the height of burr is at 0.05mm, only have described crimp, the aluminium magnet wire joint is placed in the crimping shaping dies together with copper wire lead, carry out punching press, the shape of crimp has become similar concavity by U word shape, enter to middle concave in U word shape two row tops, aluminium magnet wire joint and copper wire lead are enclosed in crimp, complete the connection of aluminium magnet wire and copper conductor.

Because copper wire lead and aluminium magnet wire joint are crimped the part bag pressure, the hair tooth in crimp on horizontal stripe can puncture the insulating barrier of aluminium magnet wire joint when punching press, makes the contact resistance of crimp and aluminium magnet wire joint almost nil, connects effect fine.

Crimp is prefabricated component, makes band shape, together with the crimping mould, is placed on stamping machine in advance.

The beneficial effects of the utility model are:

1, because in crimp, the burr on horizontal stripe can puncture the insulating barrier of aluminium magnet wire joint when punching press, so need not remove in advance the insulating barrier of aluminium magnet wire joint, saved production process.

2, because crimp and crimping mould are placed on stamping machine in advance, when punching operation, as long as aluminium magnet wire joint and copper wire lead are put into to the crimping mould, carry out punching press, just complete connection, highly efficient in productivity.

The accompanying drawing explanation

Fig. 1 is the prototype structure schematic diagram of embodiment of the present invention crimp;

Fig. 2 is the horizontal stripe of expansion in crimp and the burr amplification view on the horizontal stripe plane;

Fig. 3 is the cutaway view that crimp, copper wire lead and the aluminium magnet wire joint after punching press is connected.

Embodiment

Below in conjunction with Fig. 1, Fig. 2, Fig. 3 and an embodiment, the utility model is described in further detail:

Fig. 1, Fig. 2, Fig. 3 shows the compression bonding apparatus of a kind of aluminium magnet wire of the utility model and copper conductor, comprise aluminium magnet wire joint 1, copper wire lead 2, crimp 3, it is characterized in that: described crimp 3 is the rectangular of a U word shape, the horizontal stripe 3.1 that nine projections are arranged in described crimp 3 rectangular, described horizontal stripe 3.1 is uniformly distributed, there is the burr 3.2 of high out-of-plane on both sides on 3.1 of horizontal stripes, the height of burr 3.2 is at 0.05mm, by described crimp 3, aluminium magnet wire joint 1 is placed in the crimping mould together with copper wire lead 2, carry out punching press, the shape of crimp 3 has become similar concavity by U word shape, enter to middle concave in U word shape two row tops, tightly suppress copper wire lead 2, aluminium magnet wire joint 1, complete the connection of aluminium magnet wire and copper conductor.
