Description

Technical Field

[0001] This utility model relates to the field of semiconductor terminal technology, specifically to an integrated copper busbar structure. Background Technology

[0002] In the power semiconductor packaging industry, due to space constraints, the two copper busbars at the high-power input and output terminals are typically stacked one on top of the other, insulated by high-voltage insulating paper. Because a very lightweight insulating paper needs to be placed between the two copper busbars, manual assembly is very slow and the insulating paper is easily disturbed, causing displacement during soldering or transportation. Therefore, existing technology pre-fixes the stacked copper busbars using a mold, and then uses injection molding to fix them together, achieving a one-piece assembly.

[0003] However, in actual use, copper busbars are affected by the surrounding environment, which affects their service life. In addition, the copper busbar itself is relatively fragile and is easily damaged by external pressure and impact. Therefore, it is necessary to maintain or replace it regularly. However, in the above structure, the two are fixed by injection molding, which makes it impossible to easily disassemble the two copper busbars. The entire integrated copper busbar structure can only be scrapped, which increases the equipment maintenance cost. Utility Model Content

[0004] Based on the above description, this utility model provides an integrated copper busbar structure to solve the problem that the existing integrated copper busbar structure uses injection molding to connect and fix the two parts, which makes it impossible to disassemble and recycle them separately during subsequent maintenance, resulting in high maintenance costs.

[0005] This utility model is achieved through the following technical solution:

[0006] An integrated copper busbar structure includes a first copper busbar and a second copper busbar stacked on top of each other. Insulating paper is horizontally arranged between the first copper busbar and the second copper busbar. A first fixing seat is provided on the top surface of the first copper busbar, and a second fixing seat is provided on the bottom surface of the second copper busbar. The bottom surface of the first fixing seat and the top surface of the second fixing seat are attached to each other and locked together by a locking component.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the first copper busbar and the second copper busbar are respectively provided with connecting terminals at both ends, and the surface of the connecting terminals is provided with through holes.

[0009] Furthermore, a rectangular groove is provided at the center of the bottom surface of the first fixing base and the top surface of the second fixing base. The main bodies of the first copper busbar and the second copper busbar are respectively embedded in the rectangular groove, and the surfaces of the first copper busbar and the second copper busbar are arranged flush with the planes on both sides of the rectangular groove.

[0010] Furthermore, both sides of the first and second fixing seats are provided with flanges. The bottom surface of the flange of the first fixing seat is provided with a positioning groove, and a rod is vertically provided at the center of the bottom surface of the positioning groove. The flange surface of the second fixing seat is provided with a connecting part, and a limiting hole is provided at the center of the top surface of the connecting part. When the connecting part is inserted into the positioning groove, the rod is vertically inserted into the limiting hole.

[0011] Furthermore, the locking assembly includes an adjusting plate rotatably mounted inside the flange of the second fixed seat. The top surface of the adjusting plate is provided with a spiral groove, and multiple mounting slots are provided on the inner sidewall of the limiting hole. A locking block is slidably mounted in each mounting slot, and the bottom surface of the locking block is provided with a protrusion that extends downward and is inserted into the spiral groove.

[0012] Furthermore, an adjustment shaft is provided at the center of the bottom surface of the adjustment plate. The adjustment shaft extends downward to the bottom surface of the flange of the second fixed seat and is connected to an adjustment cap. The top surface of the adjustment cap is flush with the bottom surface of the flange of the second fixed seat.

[0013] Furthermore, the outer wall of the insertion rod is provided with a locking groove, and the locking block extends toward the center of the limiting block and is inserted into the locking groove.

[0014] Furthermore, the insulating paper extends outward on both sides and has holes on the surface of the extended portion, and the protruding portion of the insulating paper is fitted onto the connecting portion through the holes.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0016] 1. This application improves upon the existing integrated copper busbar structure by replacing the injection-molded fixing block with a detachable connection structure fixing seat. This allows workers to quickly assemble the copper busbar and insulating paper using the pre-set slots on the fixing seat, while ensuring that the insulating paper does not wobble during assembly. Moreover, this detachable structure facilitates subsequent regular maintenance, enabling the replacement of the integrated copper busbar individually. Even in the event of eventual scrapping, the copper busbar and fixing seat can be disassembled, sorted, and recycled, greatly reducing maintenance costs and making it more convenient to use.

[0023] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0025] Combination Figure 1-5 As shown, an integrated copper busbar structure includes:

[0026] The copper busbar is divided into a first copper busbar 1 and a second copper busbar 2, which are stacked one on top of the other, with the connecting terminals at both ends facing opposite directions. The surface of the connecting terminals is also provided with through holes for use in fixing and connecting with other copper busbars.

[0027] Insulating paper 3 is placed at the center of the two copper busbars to isolate the current between them;

[0028] The fixing base is divided into a first fixing base 4 and a second fixing base 5. The first fixing base 4 and the second fixing base 5 are respectively located on the outer side walls of the first copper busbar 1 and the second copper busbar 2. By squeezing, the opposite sides of the first fixing base 4 and the second fixing base 5 are made to fit together, thereby clamping and fixing the first copper busbar 1, the second copper busbar 2 and the insulating paper 3.

[0029] The locking component 7 is located inside the flanges 6 on both sides of the fixing seat to assist the fixing seat in locking and fixing, thereby replacing the bolt structure and improving the convenience of disassembly.

[0030] Specifically, in this embodiment, a rectangular groove is provided at the center of the bottom surface of the first fixing seat 4 and the top surface of the second fixing seat 5. The main body of the first copper busbar 1 and the second copper busbar 2 are respectively embedded in the rectangular groove, so that the surface of the copper busbar is flush with the end face of the fixing seat, and the insulating paper 3 is placed between the two.

[0031] In addition, since the insulating paper 3 arranged here is very easy to be tilted due to touch or shaking, which will cause the two copper busbars to come into direct contact, in order to avoid this phenomenon, the width of the insulating paper 3 should be greater than the width of the copper busbar body. In addition, a connecting part 61 should be provided on the top surface of the flange 6 on both sides of the second fixing seat 5. The connecting part 61 is set as a cylindrical structure, and a limiting hole 62 is opened at the center of the top surface, and the limiting hole 62 extends downward into the interior of the flange 6.

[0032] Simultaneously, based on the structure of the connecting part 61, the insulating paper 3 should also protrude outwards on both sides, and holes should be cut into the surface of the protruding parts. The protruding parts are then fitted onto the connecting part 61 using these holes. When both sides are fitted onto the connecting part 61, the insulating paper 3 can be initially limited and fixed. In this embodiment, the first fixing seat 4 and the second fixing seat 5 should be equipped with multiple sets (minimum two sets) according to the length of the copper busbar, for example, attached... Figure 1 As shown, the insulating paper 3 can be fixed to the surface of the second copper busbar 2 by using the four protruding parts to cooperate with the connecting part 61. Even if it is touched or shaken later, it can be ensured that the insulating paper 3 completely covers the surface of the second copper busbar 2.

[0033] A positioning groove 63 is provided on the bottom surface of the flange 6 of the first fixed seat 4. The size of the positioning groove 63 is adapted to the connecting part 61, and a vertically downward-facing insertion rod 64 is provided at the center of the bottom surface of the positioning groove 63. When the connecting part 61 abuts against the inside of the positioning groove 63, the insertion rod 64 is vertically inserted into the limiting hole 62, and the two are interlocked.

[0034] The locking assembly 7 includes an adjusting plate disposed inside the flange 6 of the second fixed seat 5. The adjusting plate is annular and is movably assembled with the inside of the flange 6 using ball bearings. In addition, a spiral groove is provided on its top surface, and an adjusting shaft is vertically disposed on its bottom surface. The adjusting shaft extends vertically downward to the bottom surface of the flange 6 and is connected to an adjusting cap 74. A circular groove of a certain size should be provided around the adjusting cap 74 so that the operator can turn it by hand.

[0035] In the above structure, the adjusting plate 71 should be arranged concentrically with the limiting hole 62. On this basis, an installation groove 72 is provided on the inner wall of the limiting hole 62. There are 4 installation grooves 72 arranged in a circumferential array. A locking block 73 is slidably installed in each installation groove 72. Both have matching sliding groove structures on their side walls, so that the locking block 73 can move along the side wall of the installation groove 72.

[0036] The bottom surface of the mounting groove 72 should extend downward and communicate with the mounting space where the adjustment plate 71 is mounted. Therefore, the bottom of the locking block 73 located inside the mounting groove 72 can be inserted into the spiral groove on the surface of the adjustment plate 71 with the protrusion facing downward. Thus, when the adjustment plate 71 is rotated, the arc-shaped inner wall of the spiral groove can be used to force the four locking blocks 73 to move synchronously toward the center or unfold outward.

[0037] To ensure the locking block 73 can firmly lock the insertion rod 64, a corresponding locking groove 65 should be provided on the outer wall of the insertion rod 64. The end of the locking block 73 is triangular, and the two parts are fastened together using a mutually compatible structure, thereby firmly fixing the insertion rod 64 inside the limiting hole 62, thus locking the first fixing seat 4 and the second fixing seat 5. Therefore, when the workers disassemble and maintain the structure or recycle it, they can easily disassemble the two copper busbars and classify and recycle the fixing seats and copper busbars. Moreover, the fixing seats can be directly reused. Because its locking structure adopts a snap-fit ​​structure, compared with the bolt fixing structure, it will not wear out due to repeated disassembly and assembly friction during long-term use, nor will it rust, resulting in a longer service life and further reducing the manufacturing cost of the entire integrated copper busbar structure.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this utility model.
