Embodiment 1

[0044] Such as Figure 1-2As shown, the conductive connection structure and method between copper materials or between copper materials and other components of the present invention adopts a multi-layer copper foil flexible soft connection structure to connect between copper materials or between copper materials and other components. The connection structure is a multi-layer structure formed by stacking wavy or serpentine or unfolded spiral copper foil strips. The two ends of the wavy or serpentine or unfolded spiral copper foil strips are connected to copper or On other components, the wavy or serpentine or unfolded spiral copper foil in the middle is in a free layered state (natural state after superimposition), and the two layers of the multilayer structure wave or serpentine or unfolded spiral copper foil The end is directly connected to copper or other components.

[0045] The copper foil soft connection parts (copper foil strips) used in the present invention are stacke...

Embodiment 2

[0047] Such as image 3 As shown, in the copper foil flexible connection structure of this embodiment, the middle part 1 of the copper foil is wavy or serpentine or unfolded spirally, and the two ends of the middle part 1 of the copper foil are the copper foil end plane 2 respectively, and the copper foil end Copper foil end screw holes 3 are opened on the top plane 2, and the copper materials or between copper materials and other components are connected through a copper foil soft connection structure, and the copper material or other components and the copper foil end plane 2 are connected through matching Copper bolts and copper foil end screw holes 3 are connected. In this embodiment, the middle part of the copper foil 1 is provided with an opening 4 in the middle part of the copper foil, which can increase the heat dissipation without affecting the convenience of passing large currents, and the vibration can be better isolated, and thermal expansion and contraction can ca...

Embodiment 3

[0050] The flexible connection structure is used to connect the conductive copper rings of the N and S pole damping windings, which is used to directly short-circuit the damping strips of all magnetic poles. After the copper solder is welded into a whole, it is connected with bolts. The main disadvantages are as follows:

[0051] 1) After the safety inspection and maintenance of the equipment, the replaced soft copper bars are not conducive to recycling and cannot more effectively meet environmental protection requirements;

[0052] 2) Welded with silver-copper solder as a whole, the vibration isolation effect is poor;

[0053] 3) The "U-shaped" structure takes up a lot of space.

[0054] In this case, the present embodiment designs the connection structure, see Figure 1-3 with Figure 5 , Image 6 shown. The copper foil flexible connection structure adopted in this embodiment is composed of wavy or serpentine or unfolded spiral copper foil and copper bolts 5. Copper fo...

Abstract

The invention relates to a connection technology between copper materials or between a copper material and other components, in particular to a structure and method for conductive connection between copper materials or between a copper material and other components. A multi-layer copper foil flexible connection structure is connected between the copper materials or between the copper material and other components, the copper foil flexible connection structure is a multi-layer structure formed by superposing wave-shaped or snake-shaped or unfolded spiral copper foil strips, the middle wave-shaped or snake-shaped or unfolded spiral copper foil strips are in a free layering state, and two ends of the wave-shaped or snake-shaped or unfolded spiral copper foil strips of the multi-layer structure are directly connected to the copper materials or other components. The structure and method for conductive connection disclosed by the invention solve the problems of unsatisfactory conductive performance, low reliability and the like of the prior art, the copper foil flexible connection which has a simple structure and high reliability and is convenient to maintain is adopted, and the conductive connection structure not only has a good conductive performance, but also has good heat compensation ability and a vibration isolation effect.

Description

technical field [0001] The invention relates to a connection technology between copper materials or between copper materials and other objects, in particular to a conductive connection structure and method between copper materials or between copper materials and other components. Background technique [0002] For equipment in metallurgy, chemical industry, electric power, electronics and other industries, the soft connection products are mainly braided flexible connection, copper bar flexible connection and rigid connection. The flexible connections in the prior art are mainly divided into braided flexible connections, copper bar flexible connections and rigid connections. The main disadvantages are: [0003] 1. Braided soft connection [0004] In the prior art, braided soft connection is often used for electrical connection of large load current. This soft connection structure is composed of multiple oxygen-free copper wires braided into soft copper strips, and then connec...
