Abstract

The utility model relates to a compound double contact silk material of jumbo size, including copper tape layer and silver-nickel layer, silver-nickel layer has two, is located the both ends on copper tape layer respectively, and silver-nickel layer passes through high temperature melting and the compound fixed connection of copper strips layer, directly compounds silver-nickel layer and copper strips layer, and the customer only needs to cut it into required size as the contact when using, has saved welding process, has improved production efficiency greatly, has saved the copper-nickel layer simultaneously, has saved purchasing cost for the customer, improves enterprise's profit the utility model discloses the advantage: 1. the welding procedure is saved, and the production efficiency is greatly improved. 2. The purchasing cost is saved for the client, and the enterprise profit is improved.

Description

Large-size composite double-contact wire material

Technical Field

The utility model relates to a silk material, concretely relates to compound two contact silk materials of jumbo size.

Background

The silk material is mostly used as the switch contact, its application range is very wide, the double contact silk material is generally used in switch or relay, the double contact silk material that uses at present, compound with silver nickel and copper nickel high temperature earlier, provide the customer with compound silk material, the customer spot welding is on the copper strips layer again after cutting into the contact, every double contact customer all needs spot welding twice like this, production efficiency is very low, and the fastness of spot welding is unstable, produce the obscission easily, cause the unqualified phenomenon of product quality, market competition is more and more intense, raw materials cost is high, in order to save the cost, must look for other methods to replace current double contact silk material under the prerequisite that does not influence the result of use.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: aiming at various defects and shortcomings in the prior art, a large-size composite double-contact wire is provided.

The utility model discloses a concrete technical scheme is: a large-size composite double-contact wire comprises a copper strip layer and two silver-nickel layers, wherein the two silver-nickel layers are respectively positioned at two ends of the copper strip layer, and the silver-nickel layers are fixedly connected with the copper strip layer in a composite mode through high-temperature melting.

The silver nickel layer and the copper strip layer are directly compounded, and a customer only needs to cut the silver nickel layer and the copper strip layer into required sizes to serve as contacts when using the contact, so that the welding process is omitted, the production efficiency is greatly improved, the copper nickel layer is omitted, the purchasing cost is saved for the customer, and the enterprise profit is improved.

The utility model discloses owing to adopted above technical scheme, had following advantage: 1. the welding procedure is saved, and the production efficiency is greatly improved. 2. The purchasing cost is saved for the client, and the enterprise profit is improved.

Detailed Description

Embodiments of the present invention will be described with reference to the accompanying drawings.

A large-size composite double-contact wire comprises a copper strip layer 1 and two silver-nickel layers 2, wherein the two silver-nickel layers 2 are respectively positioned at two ends of the copper strip layer 1, and the silver-nickel layers 2 are fixedly connected with the copper strip layer 1 in a composite mode through high-temperature melting.

Directly compound silver nickel layer 2 and copper tape layer 1, only need cut into required size with it as the contact when customer uses, saved welding process, improved production efficiency greatly, saved copper nickel layer 3 simultaneously, saved purchasing cost for the customer, improved the profit of enterprise.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.

Claims

1. A large-size composite double-contact wire material is characterized in that: the copper-nickel composite belt comprises a copper belt layer (1) and two silver-nickel layers (2), wherein the two silver-nickel layers (2) are respectively positioned at two ends of the copper belt layer (1), and the silver-nickel layers (2) are fixedly connected with the copper belt layer (1) in a compounding way through high-temperature melting.
