DETAILED DESCRIPTION

[0016] In order to enable the above-mentioned purpose, features and advantages of the utility model to be more clearly understood, the utility model will be further described in detail below in combination with the drawings and specific embodiments. It should be noted that the embodiments of the application and the features in the embodiments can be combined with each other without conflict.

[0017] For example, Figures 1-4The copper foil soft connection structure shown includes a copper foil segment 1 and a joint 2 fixed at both ends of the copper foil segment 1. The copper foil segment 1 is inserted into a preset mounting groove 21 of the joint 2 and fixed. The copper foil segment 1 is composed of multiple foil pieces 12 stacked together. Each foil piece 12 is provided with an arch structure 13 to support the adjacent two foil pieces 12. The fixing part 11 and the mounting groove 21 are both provided with a fixing hole 22. The joint 2 is also provided with an embedding groove 23 and an embedding block 24 extending from the joint 2. The embedding block 24 and the embedding groove 23 are matched in size. The embedding groove 23 and the embedding block 24 are provided with corresponding bolt holes 25.

[0018] As a further arrangement of the above scheme, the convex surface 131 of the arch structure 13 is larger in profile size than the concave surface groove 132. Figure 1 As shown, the arch structure 13 provided on the foil piece 12 is curved from the middle of the foil piece 12 to the two sides as the center line, and is convex in the direction of the two sides, that is, the convex surface 131 takes the middle of the multiple foil pieces 12 as the center line, so that the arching state of the foil pieces 12 on both sides is mirror-imaged.

[0019] As a further arrangement of the above scheme, the embedding block 24 and the embedding groove 23 are also provided with a corresponding tin liquid groove 28. The tin liquid groove 28 occupies a part of the embedding groove 23 and the embedding block 24, and is connected with the mating joint of the embedding block 24 and the embedding groove 23. When the soldering tin liquid is introduced, the soldering tin liquid can flow into the mating joint of the embedding block 24 and the embedding groove 23 from the gap.

[0020] As a further arrangement of the above scheme, the embedding block 24 and the embedding groove 23 are also provided with a crease groove 29, which is located in the middle position of the two.

[0021] As a further arrangement of the above scheme, the embedding groove 23 and the embedding block 24 are arranged in a structure with a large end and a small connection, which can make it difficult for the two copper foil soft connections to be separated from the horizontal direction after being connected.

[0022] As a further arrangement of the above scheme, the fixing hole 22 is provided with a rivet hole 26 on the outside of the joint 2. The structure of the rivet hole 26 is that a counterbore larger than the diameter of the fixing hole 22 is provided on the outside of the joint 2. The counterbore is provided to facilitate the connection between the joint 2 and the copper foil segment 1. The setting at this position enables a pin rivet with the same diameter as the fixing hole 22 to be deformed at the end under pressure and embedded into the rivet hole 26, forming a I-shaped structure to fix the two, improving the fixing strength and stability.

[0023] Reference Figures 1-3The copper foil soft connection structure shown comprises multiple layers of foil 12 with an arching structure 13, the arching structure 13 provides the function of supporting the two layers of foil 12 between the upper and lower layers, and the gap formed between the two sides of the supported foil 12 can allow better heat dissipation.

[0024] The opposite fixed holes 22 on the copper foil segment 1 and the joint 2 are provided with matching pin rivets, which can allow the copper foil segment 1 and the joint 2 to be firmly connected, such as Figure 1 As shown, after the fixed part 11 of the copper foil segment 1 is inserted into the mounting groove 21 of the joint 2, the pin rivet is sequentially inserted through the joint 2, the copper foil segment 1, and the joint 2, and then the two ends are extruded and deformed to be embedded in the rivet hole 26 through a pressure device or tool, so that the two ends of the pin rivet are deformed and cannot pass through the fixed hole 22 to form a fixed connection.

[0025] As shown, Figures 1-2 As shown, the embedding groove 23 and the embedding block 24 of the embodiment are also provided with opposite tin liquid grooves 28, which can be used for filling solder liquid after connection to enhance the connection strength of the two, especially for some use scenarios that require tight connection strength, the tin liquid groove 28 is filled with molten solder liquid, which not only fills the tin liquid groove 28, but also fills the connection gap between the embedding groove 23 and the embedding block 24, so as to eliminate the joint as much as possible, improve the connection, and reduce the electrical loss to a certain extent and improve the electrical conductivity.

[0026] As shown, Figure 4 As shown, during normal use, the staff can also selectively fold the embedding block 24 on the joint 2 towards the embedding groove 23, so that the two are embedded and fitted, and the bolt holes 25 on the two can be fixed by bolts after fitting, it is worth noting that in order to fold and embed the two, the embodiment is also provided with a crease groove 29 at the connection part of the folding surface of the embedding groove 23 and the embedding block 24, the crease groove 29 can make the embedding block 24 more easily folded when folded relative to the embedding groove 23, and the folding position is also more accurate, avoiding the problem of embedding misalignment.

[0027] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the present application and equivalent technology, the present application also intends to include these modifications and variations.
