Copper strip flexible connection part facilitating heat dissipation

Abstract

The invention discloses a flexible copper strip connection that is easy to dissipate heat, comprising a copper strip, a protrusion, a heat dissipation hole, a first copper foil, a second copper foil, a third copper foil, a bump and a tinned heat dissipation layer. In the present invention, protrusions are provided on the outer surfaces of both sides of the copper strip, which increases the heat dissipation area on the surface of the copper strip and makes the copper strip itself easier to dissipate heat; The side of the fixing hole is provided with a cooling hole, which solves the problem that a large amount of heat is easily generated at the joint of the copper strip soft connection, and realizes a timely and effective heat dissipation function; the bumps on the first copper foil and the second copper foil are connected with the third copper foil The outer surfaces of the bumps set on the foil are welded to each other, realizing the formation of through holes between the inner bumps that are softly connected by the copper strip, which is good for heat dissipation; the copper strip is provided with a tin-plated heat dissipation layer, and the heat dissipation layer has a good heat dissipation effect. It helps the heat dissipation of the copper strip, and solves the problem of difficult heat dissipation in the soft connection of the current high-current copper strip.

Description

technical field [0001] The invention relates to the technical field of circuit connection, in particular to a copper strip flexible connection that is easy to dissipate heat. Background technique [0002] Soft connection, copper bar soft connection Tinned copper braided soft connection is suitable for various high-voltage electrical appliances, vacuum appliances, mining explosion-proof switches and automobiles, locomotives and other related products for soft connection, using bare copper wire or tinned copper braiding Wire (stranded wire), made by cold pressing. The bonding interface of the copper bar soft connection is formed by one-time welding with molecular diffusion welding technology. The product has the characteristics of good quality, strong conductivity, large current withstand, small resistance value, and durability. Widely used in metallurgy (such as: electrolytic aluminum, electrolytic zinc, electrolytic copper), chemical industry (such as: electroplating), whee...
