Description

Technical Field

[0001] This utility model mainly relates to the field of supercapacitor system technology, specifically a supercapacitor module terminal block and its welding fixture. Background Technology

[0002] In a supercapacitor module, the input and output terminals are composed of connecting posts, which are made up of tabs and tab connecting pieces. Due to the requirements of subsequent housing assembly, in the initial design, two cylinders of different diameters with steps at one end of the tabs were made, and a flat surface was machined on one of the cylinders for positioning.

[0003] Meanwhile, the electrode connecting piece is provided with corresponding steps and holes. A flat surface is machined on one of the holes for positioning. Before welding, the electrode and the electrode connecting piece are installed together. When processing the electrode and the electrode connecting piece, multiple processing steps are required. The processing steps are numerous, and the process needs to be switched during processing, which increases the processing difficulty and the difficulty of quality assurance, resulting in excessive processing costs. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. It mainly provides a supercapacitor module terminal block and its welding fixture, which solves the technical problem mentioned in the background that traditional electrode tabs and electrode tab connecting pieces have many processing steps, require process switching, and thus increase the difficulty of processing and quality assurance, potentially leading to excessively high processing costs.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A supercapacitor module terminal block includes a supercapacitor cell, wherein the supercapacitor cell is provided with a supercapacitor module connection post.

[0006] The supercapacitor module connection post consists of tabs and tab connecting pieces, and the tabs and tab connecting pieces are interconnected.

[0007] More preferably, the supercapacitor cells are provided in multiple units, and the supercapacitor cells are connected to each other by capacitor connecting pieces.

[0008] More preferably, the tab has a cylinder, and the tab connecting piece has a circular hole, which forms a clearance fit with the cylinder.

[0009] More preferably, both the electrode tab and the electrode tab connecting piece have a flat surface.

[0010] A supercapacitor module terminal block includes a welding fixture for welding the terminal block. The welding fixture includes a fixture body, on which are formed grooves that match the external structure of the tab connecting piece and stepped holes that match the external structure of the tab.

[0011] More preferably, the contoured groove and the contoured stepped hole together form a positioning hole, which matches the external structure of the supercapacitor module connecting column, and the tooling body is provided with a number of positioning holes, which are distributed in a uniform and equidistant manner.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The optimized design of the terminal block and its welding fixture, through optimization of the electrode tab and electrode tab connecting piece, eliminates the stepped cylinder and positioning plane of the electrode tab, and eliminates the stepped hole and positioning plane of the electrode tab connecting piece, simplifying the structure, reducing processing steps, reducing processing difficulty and quality control difficulty, and thus reducing processing costs.

[0013] Furthermore, there is no need to spend time finding the positioning surface before welding. Simply place the optimized electrode tab and electrode tab connecting piece into the stepped hole and groove of the welding fixture to complete the positioning, which can shorten the assembly time and improve welding efficiency.

[0019] Please refer to the appendix carefully. Figure 1-7 A supercapacitor module terminal block includes a supercapacitor cell 2, and a supercapacitor module connection post 1 is provided on the supercapacitor cell 2.

[0020] The supercapacitor module connection post 1 consists of a tab 101 and a tab connecting piece 102, and the tab 101 and the tab connecting piece 102 are connected to each other.

[0021] In this embodiment, as Figure 1 As shown, there are multiple supercapacitor cells 2, and each supercapacitor cell 2 is connected to the others by capacitor connecting pieces 3; multiple supercapacitor cells 2 can be connected by capacitor connecting pieces 3 according to different capacity / power requirements.

[0022] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the electrode tab 101 is provided with a cylinder 10101, and the electrode tab connecting piece 102 is provided with a circular hole, which forms a clearance fit with the cylinder 10101; the cylinder 10101 on the electrode tab 101 and the circular hole on the electrode tab connecting piece 102 provide positioning guidance for the two during assembly, reducing the difficulty of alignment and improving the accuracy of subsequent welding.

[0023] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, both the tab 101 and the tab connecting piece 102 have a flat surface, which is used to cooperate with the welding fixture 4 of the connecting column to achieve positioning. By fitting and limiting the plane, the relative position of the two in the welding fixture is accurately fixed, avoiding displacement during assembly and improving the positioning accuracy before welding.

[0024] A supercapacitor module terminal block includes a terminal block welding fixture 4 for welding the terminal block. The terminal block welding fixture 4 includes a fixture body 401. The fixture body 401 has a contoured groove 402 that matches the external structure of the tab connecting piece 102 and a contoured stepped hole 403 that matches the external structure of the tab 101.

[0025] The contouring structure can limit the fit of the tab connecting piece 102 and the tab 101, ensuring that their installation positions in the tooling match the preset welding posture, avoiding welding deviations caused by component misalignment, and improving positioning accuracy. Furthermore, the contouring groove 402 and the contouring stepped hole 403 can provide stable support for the tab connecting piece 102 and the tab 101 respectively. At the same time, the adaptable contouring structure can reduce the difficulty of component placement for operators, eliminating the need for repeated alignment adjustments, shortening tooling assembly time, and improving overall welding operation efficiency.

[0026] In this embodiment, as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the contoured groove 402 and the contoured stepped hole 403 together form a positioning hole. This positioning hole matches the external structure of the supercapacitor module connecting post 1. Several positioning holes are provided on the tooling body 401, and these positioning holes are distributed in a uniform and equidistant manner. The positioning hole formed by the contoured groove 402 and the contoured stepped hole 403 can prevent relative misalignment when the tab 101 and the tab connecting piece 102 are assembled, ensuring the uniform overall posture of the supercapacitor module connecting post 1 during welding. At the same time, the several uniformly spaced positioning holes provided on the tooling body 401 can meet the synchronous welding requirements of multiple sets of supercapacitor module connecting posts 1, improving the efficiency of mass production.

[0027] The specific operation process of this utility is as follows: The supercapacitor module connecting post 1 is composed of an optimized tab 101 and a tab connecting piece 102. The cylindrical 10101 on the tab 101 and the circular hole on the tab connecting piece 102 form a clearance fit, which can provide a stable positioning guide for the assembly of the two. Both the tab 101 and the tab connecting piece 102 are provided with a plane. The contact limit of the plane can ensure the accurate relative position of the two, laying a reliable foundation for the subsequent welding process. On the main body 401 of the welding fixture 4 for the connecting column, there are corresponding contoured grooves 402 that match the structure of the tab connecting piece 102, and contoured stepped holes 403 that match the structure of the tab 101. Together, they form positioning holes that are adapted to the connecting column 1 of the supercapacitor module, which can limit the displacement of the tab 101 and the tab connecting piece 102. At the same time, several positioning holes evenly and equidistantly distributed on the main body 401 of the fixture can meet the synchronous welding requirements of multiple sets of connecting columns, greatly improving the welding operation efficiency. During welding operations, simply place the tab connecting piece 102 and the tab 101 into the contoured groove 402 and contoured step hole 403 of the tooling body 401 respectively to perform welding work. The operation is convenient and the positioning is accurate. During the supercapacitor module assembly stage, multiple supercapacitor cells 2 with supercapacitor module connecting posts 1 can be connected through capacitor connecting pieces 3 according to different capacity or power requirements of actual use scenarios, ultimately forming a complete and performance-adapted supercapacitor module.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
