Abstract

The utility model provides a welding knife for directly welding an aluminium-in-copper enamelled wire. The welding knife for directly welding the aluminium-in-copper enamelled wire comprises two electrodes which are integrally adhered to each other, wherein an insulating layer is arranged between the two electrodes; a tip part is arranged at one end of each electrode; and a machining gap is formed in the middle of the tip part. The machining gap is formed at the front end of the welding knife for directly welding the aluminium-in-copper enamelled wire, so that loss of welding energy is reduced; meanwhile, the end part of the welding knife is melted by a laser beam at a high temperature, so that the welding knife has a relatively high resistance to high temperature and is applicable for welding the aluminium-in-copper enamelled wire.

Description

A kind of weldering cutter of direct welding copper-in-aluminum enameled wire

Technical field

The utility model relates to the weldering cutter, a kind of specifically weldering cutter of direct welding copper-in-aluminum enameled wire.

Background technology

In the electronics industry production field; The copper enamel-covered wire is a kind of wire rod commonly used; But along with the increase day by day of production demand, directly adopt the copper enamel-covered wire can cause the production cost of electronic devices and components too high, cause the profit of electronic devices and components more and more lower; So industry has adopted a kind of copper-in-aluminum enameled wire instead of copper enamel-covered wire, to reduce production costs.

Though adopt copper-in-aluminum enameled wire to greatly reduce production cost, copper-in-aluminum enameled wire has strict more requirement for welding sequence, perhaps putting soldering tip can only weld gold thread, silver-colored line, tin copper cash and copper enamel-covered wire to electrode in the past; But can't directly weld copper-in-aluminum enameled wire, because copper-in-aluminum enameled wire is made up of two kinds of metals, skin is a copper product; And inside is aluminum metal, because the fusing point of two kinds of metal materials of copper and aluminium is different, the fusing point of copper is 1084 ℃; And the fusing point of aluminium is 660 ℃; So will be on metal substrate with the copper-in-aluminum enameled wire direct spot welding, in case electrode in the past or put soldering tip and can't accomplish is electrode or to put the most advanced and sophisticated temperature of soldering tip too high; The inner aluminum metal of copper-in-aluminum enameled wire can produce splash phenomena; And temperature is crossed and low the illusive phenomenon of spot welding can be occurred, in the process of direct welding copper-in-aluminum enameled wire, has serious defective so use traditional electrode or put soldering tip, can directly influence the quality of electronic product.

The utility model content

To the deficiency and the defective of above prior art, the purpose of the utility model is to provide a kind of weldering cutter of direct welding copper-in-aluminum enameled wire.

The purpose of the utility model realizes through adopting following technical scheme:

A kind of weldering cutter of direct welding copper-in-aluminum enameled wire comprises electrode, and said electrode is provided with two, and these two electrode adhesion are one, is provided with insulating barrier between wherein, and an end of these two electrodes is provided with point, and the middle part of this point is provided with a machining gap.

As the optimal technical scheme of the utility model, said insulating barrier is a mica sheet.

As the optimal technical scheme of the utility model, the thickness of said mica sheet is 0.05mm.

As the optimal technical scheme of the utility model, said machining gap is not more than 0.1mm.

As the optimal technical scheme of the utility model, the width of said point end is 0.05mm～0.35mm.

Compared with prior art, the weldering cutter that the utility model disclosed, its front end is provided with a machining gap; Reduced the loss of welding energy, simultaneously, after the laser beam high-temperature fusion is adopted in the end of weldering cutter; Have stronger high-temperature tolerance, be applicable to the welding of copper-in-aluminum enameled wire.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:

Fig. 1 is the structural representation of the weldering cutter of a kind of direct welding copper-in-aluminum enameled wire of the utility model.

Fig. 2 is the enlarged diagram in a zone among Fig. 1.

The specific embodiment

See also Fig. 1 and Fig. 2, be respectively the enlarged diagram in a zone among structural representation and Fig. 1 of weldering cutter of a kind of direct welding copper-in-aluminum enameled wire of the utility model.

This weldering cutter is made up of the consistent electrode 101 of two size shape; These two electrodes 101 are bonded as one, are provided with insulating barrier 102 between wherein, and this insulating barrier 102 is a mica sheet; Its thickness is 0.05mm; One end of these two electrodes 101 is provided with point 105, and the middle part of this point 105 is provided with a machining gap 103, and this machining gap 103 is not more than 0.1mm.

Wherein, the laser beam high-temperature fusion is adopted in the end 104 of the point 105 of two electrodes 101, and the width of these point 105 ends 104 is 0.05mm～0.35mm after the fusion.

Above-mentioned weldering cutter, its point 105 is provided with a machining gap 103, has reduced the loss of welding energy, simultaneously, after the point 105 of weldering cutter adopts the laser beam high-temperature fusion, has stronger high-temperature tolerance, is applicable to the welding of copper-in-aluminum enameled wire.

The preferred embodiment that the above is merely the utility model is not the practical range that is used for limiting the utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by the scope of the utility model claims.
