Copper strip flexible connection part facilitating heat dissipation

Abstract

The invention discloses a copper strip flexible connection part facilitating heat dissipation, and the connection part comprises a copper strip, projections, a heat dissipation hole, a first copper foil piece, a second copper foil piece, a third copper foil piece, a convex block, and a tin-coated heat dissipation layer. The external surfaces of the two sides of the copper strip are provided with projections, thereby increasing the heat dissipation area of the surface of the copper strip, and enabling the copper strip to be easier to cool. A connection fixing part is provided with a connection fixing hole, and the side surface, perpendicular to the connection fixing hole, of the connection fixing part is provided with a heat dissipation hole, thereby solving a problem that a large amount of heat is liable to be generated at a copper strip flexible connection point, and achieving the timely and effective heat dissipation function. The external surfaces of the convex blocks on the first and second copper foil pieces and the external surface of the convex block on the third copper foil piece are welded together, thereby achieving the forming of through holes between the internal convex blocks of the copper strip flexible connection part, and facilitating the heat dissipation. The copper strip is provided with the tin-coated heat dissipation layer, and the tin-coated heat dissipation layer is good in heat dissipation effect, thereby facilitating the heat dissipation of the copper strip, and solving a problem that a conventional large-current copper strip flexible connection part is difficult to cool.

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.
