[0036] The following is a specific embodiment of the utility model and further describes the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.

[0037] Please refer to Figures 1-5 The utility model discloses a temporary connecting structure of connecting terminal, comprising:

[0038] The first metal piece 100 has a first surface and a second surface opposite to each other, and is provided with a first connecting hole 110 penetrating the first surface and the second surface;

[0039] The second metal piece 200 is attached to the first surface of the first metal piece 100, and is provided with at least two connecting pieces 220 penetrating the first connecting hole 110 and abutting against the second surface;

[0040] The first connecting hole 110 has a maximum inner diameter in the first direction greater than that in the second direction, and the first direction intersects with the second direction.

[0041] Specifically, the second metal piece 200 is attached to the first surface of the first metal piece 100, and the at least two connecting pieces 220 are bent after penetrating the first connecting hole 110 and abut against the second surface of the first metal piece 100, so as to fix the first metal piece 100 and the second metal piece 200 relative to each other, avoid displacement of the first metal piece 100 and the second metal piece 200 during welding, and ensure that the second metal piece 200 can cover the first metal piece 100 in the correct position.

[0042] It should be noted that the first metal piece 100 and the second metal piece 200 are not easy to move horizontally due to the fixation of the at least two connecting pieces 220, but the first metal piece 100 and the second metal piece 200 can still rotate relative to each other during welding due to the less constraint of the connecting pieces 220 on the rotating direction.

[0043] Therefore, the first connecting hole 110 in the present application is not a circular hole with equal inner diameter, but is set as other shapes (such as rhombus, parallelogram or waist shape) with different inner diameters, so that the two connecting pieces 220 abut against the inner wall of the first connecting hole 110, which can prevent the first metal piece 100 and the second metal piece 200 from rotating relative to each other, thereby improving the stability of the first metal piece 100 and the second metal piece 200 during welding.

[0044] It should be noted that the second direction is any direction intersecting with the first direction, and the inner diameter of the first direction is greater than that of the second direction, that is, the inner diameter of the first direction is the maximum inner diameter of the first connecting hole 110.

[0045] Then, the two connecting pieces 220 are arranged at the two ends of the maximum inner diameter, so that the distance between the two connecting pieces 220 is maximized, and the force arm formed between the two connecting pieces 220 is the longest. If the relative rotation of the first metal piece 100 and the second metal piece 200 is required, a greater driving force needs to be applied. In this way, the constraint force of the two connecting pieces 220 on the two metal pieces in the rotation direction can be further improved.

[0046] Further, the first connecting hole 110 is a waist hole, and the length direction of the waist hole is parallel to or coincides with the first direction.

[0047] Further, the cross section of the first connecting hole 110 is polygonal, and a plurality of connecting pieces 220 are arranged at the corners of the polygon, respectively.

[0048] Further, the cross section of the first connecting hole 110 is rhombic, and two connecting pieces 220 are arranged at two opposite corners of the rhombus, respectively.

[0049] Further, the connecting piece 220 includes a first connecting section 221 and a second connecting section 222, and the connecting piece 220 has an initial state and a connecting state.

[0050] In the initial state, the first connecting section 221 and the second connecting section 222 are in the same plane.

[0051] In the connecting state, the first connecting section 221 is arranged in the first connecting hole 110 and abuts against the inner wall of the first connecting hole 110, and the second connecting section 222 abuts against the second surface.

[0052] The connecting piece 220 can be deformed from the initial state to the connecting state.

[0053] Further, the second metal piece 200 has a cutting part, which is used to cut a second connecting hole 210 that can at least partially coincide with the first connecting hole 110, and form at least two connecting pieces 220.

[0054] Specifically, the second metal piece 200 is punched from a profile, and the second connecting hole 210 and the two connecting pieces 220 are punched simultaneously to reduce the processing procedures and processing cost and improve the processing efficiency. After the punching, the two connecting pieces 220 are perpendicular to the second metal piece 200, and the two connecting pieces 220 are passed through the first connecting hole 110 during assembly, and the second connecting section 222 is bent to be attached to the second surface by using a mold. That is, the mold is provided with two pressing blocks, the two pressing blocks are inserted between the two connecting pieces 220 and gradually move outward, and the second connecting section 222 is pressed and bent, so that the second connecting section 222 is attached to the second surface. In this way, the assembly of the temporary connecting structure is completed.

[0055] Further, in the connecting state, the first connecting section 221 is attached to the inner wall of the first connecting hole 110.

[0056] The first connecting section 221 is attached to the inner wall of the first connecting hole 110, which increases the contact area of the connecting piece 220 and the first metal piece 100, and can enhance the connection strength of the first metal piece 100 and the second metal piece 200, and avoid mispositioning of the first metal piece 100 and the second metal piece 200 during welding.

[0057] Further, the first metal piece 100 is a copper sheet, the second metal piece 200 is a nickel sheet, one of the nickel sheets is connected to each end of the copper sheet, and the two nickel sheets are on the same side of the copper sheet.

[0058] Please refer to Figure 6 The application further discloses a conductive connecting piece comprising the temporary connecting structure of the connecting terminal.

[0059] Further, the application further comprises:

[0060] The main body comprises a plurality of first metal pieces 100 stacked.

[0061] Two second metal pieces 200 are connected to the two sides of the main body.

[0062] Specifically, a plurality of first metal pieces 100 are arranged in the middle, two second metal pieces 200 are arranged on the first metal pieces 100 on the two sides, respectively, and the second metal pieces 200 and the first metal pieces 100 are temporarily fixed by the connecting pieces 220; finally, all the first metal pieces 100 and the second metal pieces 200 are fixed together by welding; finally, a larger circular hole or a hole with other shapes (the hole is used for connecting an electrode column or other conductive devices) is punched at the positions of the first connecting hole 110 and the second connecting hole 210, and all the connecting pieces 220 are cut off to form a final product required.
