A quad-segment dual-diode circuit module structure

Abstract

This utility model discloses a four-segment dual-diode circuit module structure, including a negative terminal box and a positive terminal box. The negative terminal box includes a first edge metal base plate a, a first busbar through hole a, a middle metal base plate b, and a jumper through hole a. The first edge metal base plate b and the first busbar through hole b are fitted with limiting strips a and b. After limiting strips a and b are installed in the through holes on both the negative and positive terminal boxes, when a line passes through, the stacked limiting strips a and b restrict the position of the line, allowing the line to be arranged along a prescribed path. This ensures that the lines are closely arranged but do not interfere with each other. The clamping effect of the limiting strips a and b on the line effectively prevents the line from moving within the through holes. At the same time, when a circuit fault occurs and the line needs to be troubleshooted, the neat and orderly line layout benefits from the positioning effect of the limiting strips.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides, for example Figure 1-5 The diagram shows a four-segment dual-diode circuit module structure, including a negative terminal box 1 and a positive terminal box 14.

[0029] The negative terminal box 1 includes a first edge metal base plate a3, a first busbar through hole a5, a middle metal base plate b7, a jumper through hole a9, a first edge metal base plate b11, and a first busbar through hole b12;

[0031] A first busbar through-hole a5 is formed inside the upper outer wall of the first edge metal base plate a3; a jumper through-hole a9 is formed inside the upper outer wall of the middle metal base plate b7; a first busbar through-hole b12 is formed inside the upper outer wall of the first edge metal base plate b11; the positive terminal box 14 includes a second edge metal base plate a16, a second busbar through-hole 17, a jumper through-hole b18, a second edge metal base plate b20, and a diode c21; the diode c21 is disposed between the second edge metal base plate a16 and the second edge metal base plate b20; the second edge metal base plate a16 and the second edge metal base plate b20 are connected. The upper outer wall of the base plate b20 is provided with second busbar through holes 17, and the upper outer wall of the second edge metal base plate a16 is provided with jumper through holes b18. A circuit body 23 is provided between the lower outer walls of the negative terminal box 1 and the positive terminal box 14. The busbar passes through the first busbar through hole a5 from the bottom of the first edge metal base plate a3, and is then welded and fixed on the corresponding fixed platform. Another busbar passes through the first busbar through hole b12 of the first edge metal base plate b11 and is welded and fixed. The vertical jumper passes through the jumper through hole a9 of the middle metal base plate b7 and is connected to the corresponding fixed platform. Secure the jumpers that were disconnected on both sides together. Solder diodes a6 and b10 between the first edge metal base plate a3, the middle metal base plate b7, and the first edge metal base plate b11, respectively, to complete the diode connection. Install multiple limiting strips a25 and b26 inside the first busbar through-hole a5, jumper through-hole a9, and first busbar through-hole b12, ensuring they are stacked to restrict the position of the passing lines, thus completing the assembly of the negative terminal box 1. Then install the positive terminal box 14, passing the busbar through the second edge metal base plate a16 and the second... The second busbar through hole 17 of the edge metal base plate b20 is welded and fixed at the corresponding position. The jumper wire is passed through the jumper through hole b18 of the second edge metal base plate a16 and fixed. The diode c21 is welded between the second edge metal base plate a16 and the second edge metal base plate b20. Multiple limiting strips a25 and limiting strips b26 are installed inside the second busbar through hole 17 and the jumper through hole b18. Then the assembled negative terminal box 1 and positive terminal box 14 are connected to the circuit body 23 through the lower outer wall to ensure a firm connection and form a complete four-segment assembly dual diode circuit module structure.

[0032] Multiple limiting strips a25 and b26 are provided inside the first busbar through hole a5, jumper through hole a9, first busbar through hole b12, second busbar through hole 17, and jumper through hole b18. The multiple limiting strips a25 and b26 inside the first busbar through hole a5, jumper through hole a9, first busbar through hole b12, second busbar through hole 17, and jumper through hole b18 stack each other to restrict the position of the passing wires, ensuring that the busbars, jumpers, and other wires remain in a fixed position within the through holes, preventing the wires from shifting due to vibration, temperature changes, or other factors during equipment operation, thereby ensuring the stability and reliability of the circuit connection.

[0033] like Figure 4 and Figure 5 As shown, the first busbar through hole a5, jumper through hole a9, first busbar through hole b12, second busbar through hole 17 and jumper through hole b18 are all provided with multiple partition plates 28 to separate the limiting strip a25 and the limiting strip b26.

[0034] Through the partition plate 28, the limiting strips a25 and b26 in different areas can restrict different parts of the line respectively, avoiding mutual interference or squeezing of the lines in the perforation. The opening 27 alleviates the pressure on the line to a certain extent, reducing the wear of the outer sheath or damage to the internal conductor caused by excessive squeezing of the line.

[0035] like Figure 1 As shown, the negative electrode box 1 also includes a fixing hole a2, a first busbar welding fixing platform a4, a jumper welding fixing platform 8, and a first busbar welding fixing platform b13. Fixing holes a2 are provided inside the upper outer wall of the first edge metal base plate a3 and the first edge metal base plate b11, respectively, near the front and rear sides. The first busbar welding fixing platform a4 is fixedly connected to the center of the upper outer wall of the first edge metal base plate a3. The jumper welding fixing platform 8 is fixedly connected to the center of the upper outer wall of the middle metal base plate b7. The first busbar welding fixing platform b13 is fixedly connected to the center of the upper outer wall of the first edge metal base plate b11.

[0036] Align the protruding fixing support of the junction box body with the fixing hole a2 on the first edge metal base plate a3 and the first edge metal base plate b11. Then, use screws, rivets, or other suitable fixing tools to firmly fix the fixing support in the fixing hole a2, ensuring the stability of the frame structure of the negative terminal junction box 1. Pass the busbar through the first busbar through hole a5 from the bottom of the first edge metal base plate a3. Accurately place the end of the busbar on the first busbar welding fixing platform a4, and perform welding operations using welding equipment to ensure that a connection is formed between the busbar and the first busbar welding fixing platform a4. With good electrical and mechanical connections, another busbar is passed through the first busbar through-hole b12 from the bottom of the first edge metal base plate b11, and its end is placed on the first busbar welding and fixing platform b13 for welding and fixing, thus completing the installation of the busbars on both sides of the negative terminal box 1. The vertical jumper is passed through the jumper through-hole a9 from one side of the middle metal base plate b7, so that both ends of the jumper are located on the jumper welding and fixing platform 8. The jumper is welded to the jumper welding and fixing platform 8 using an appropriate welding process to ensure that the jumper connection is firm and realize the electrical connection of the lines on both sides.

[0037] like Figure 2 As shown, the positive electrode box 14 also includes a fixing hole b15 and a second busbar welding platform 19. Fixing holes b15 are provided inside the upper outer wall of the second edge metal base plate a16 and the second edge metal base plate b20, respectively, near the front and rear sides. The second busbar welding platform 19 is fixedly connected to the center of the upper outer wall of the second edge metal base plate a16 and the second edge metal base plate b20.

[0038] Accurately align the fixing support for fixing the positive terminal box 14 with the fixing holes b15 on the second edge metal base plate a16 and the second edge metal base plate b20. Use appropriate fixing tools, such as screwdrivers and rivet guns, to firmly fix the fixing support in the fixing holes b15, ensuring the frame structure of the positive terminal box 14 is stable and reliable. Pass the busbar through the second busbar through hole 17 from the bottom of the second edge metal base plate a16 and the second edge metal base plate b20 respectively. Accurately place the end of the busbar on the corresponding second busbar welding platform 19. Use appropriate welding equipment and processes to perform welding operations. During the welding process, ensure the welding quality so that a good electrical and mechanical connection is formed between the busbar and the second busbar welding platform 19.

[0039] like Figure 3 As shown, the negative terminal 22 is provided on the left side of the circuit body 23, and the positive terminal 24 is provided on the right side of the circuit body 23.

[0040] When the entire circuit is powered on, the current flows out from the negative terminal 22 of the circuit body 23 and into the negative terminal box 1. After flowing out from the negative terminal box 1, the current enters the positive terminal box 14 through the connection channel with the circuit body 23. In the positive terminal box 14, the current is transmitted through the connection formed by the busbar on the second busbar welding platform 19. After being controlled by the diode C21, the current flows to the positive terminal 24.

[0041] The implementation principle of this embodiment is as follows: A busbar is passed through the first busbar through-hole a5 from the bottom of the first edge metal base plate a3, and then welded and fixed on the corresponding fixed platform. Another busbar is passed through the first busbar through-hole b12 of the first edge metal base plate b11 and welded and fixed. A vertical jumper is passed through the jumper hole a9 of the middle metal base plate b7 and fixed on the corresponding fixed platform, connecting the disconnected jumpers on both sides. Diodes a6 and b10 are welded between the first edge metal base plate a3, the middle metal base plate b7, and the first edge metal base plate b11, respectively, completing the diode connection. Multiple limiting strips a25 and b26 are installed inside the first busbar through-hole a5, jumper hole a9, and first busbar through-hole b12 to ensure they are stacked and can restrict the position of the passing lines, thus completing the assembly of the negative terminal box 1. Subsequently, the positive terminal box 14 is installed. The busbar is passed through the second busbar through-hole 17 of the second edge metal base plate a16 and the second edge metal base plate b20, and welded and fixed in the corresponding position. The jumper wire is passed through the jumper through-hole b18 of the second edge metal base plate a16 and fixed. The diode c21 is welded between the second edge metal base plate a16 and the second edge metal base plate b20. Multiple limiting strips a25 and b26 are installed inside the second busbar through-hole 17 and the jumper through-hole b18. Then, the assembled negative terminal box 1 and positive terminal box 14 are connected to the circuit body 23 through the lower outer wall to ensure a firm connection and form a complete four-segment dual diode circuit module structure. The stacked components restrict the position of the lines passing through, ensuring that the busbar, jumper wire and other lines remain in a fixed position in the through-hole, preventing the lines from shifting due to vibration, temperature changes and other factors during equipment operation, thereby ensuring the stability and reliability of the circuit connection.
