[0046] Please refer to Figures 1 to 6In the first embodiment of the present application, a prefabricated combination pin plate 10 for capacitor production is proposed. The prefabricated combination pin plate 10 for capacitor production includes an upper combination plate 11 and a lower combination plate 12. The upper combination plate 11 includes two first side edges 16, and a plurality of slots 129 are arranged on the first side edges 16; specifically, the upper combination plate 11 is a rectangular plate having two first side edges 16. A plurality of slots 129 are arranged on each first side edge 16. These slots 129 are used to receive corresponding tenons 130 on the lower combination plate 12 to ensure precise alignment of the upper combination plate 11 and the lower combination plate 12. The lower combination plate 12 includes two second side edges 17, and a plurality of tenons 130 are arranged on the second side edges 17; specifically, the lower combination plate 12 matches the shape and size of the upper combination plate 11, and is also a rectangular plate, and the lower combination plate has two second side edges 17. A plurality of tenons 130 are provided on each second side edge 17 , and the tenons 130 are adapted to the slots 129 on the upper assembly plate 11 so as to be accurately embedded in the slots 129 during assembly.

[0047] When the upper assembly plate 11 and the lower assembly plate 12 are assembled together, the plurality of tenons 130 are arranged in a one-to-one correspondence in the plurality of slots 129. Specifically, when assembled, the upper assembly plate 11 and the lower assembly plate 12 are precisely aligned through the cooperation of the slots 129 and the tenons 130. This not only simplifies the assembly process, but also effectively avoids the problem of poor electrical contact of the produced capacitors by reducing alignment errors. Through precise mechanical docking, the risk of poor contact between the pins and the capacitor body 13 can be greatly reduced, and the possibility of damage to the capacitor during use is reduced, thereby improving the yield and reliability of the product.

[0048] Please continue to refer to Figure 7 In some specific embodiments, the tenon 130 is provided with a base 131, a first protrusion 132 and a second protrusion 133; the base 131 is arranged flush with the second side 17, and the first protrusion 132 and the second protrusion 133 both protrude from the second side 17. Specifically, the base 131 is flush with the second side 17 to maintain the overall structural consistency and stability. The base 131 provides the main support for the tenon 130 to ensure that the tenon 130 can be stably connected to the lower assembly board 12. The first protrusion 132 is located on the base 131, protruding from the second side 17, and is used to be inserted into the corresponding slot 129 in the upper assembly board 11. The shape and size of the first protrusion 132 precisely match the corresponding slot 129 to achieve precise mechanical docking and stable fixation. The second protrusion 133 is also located on the base 131, and the second protrusion 133 works together with the first protrusion 132, and also protrudes from the second side 17. The second protrusion 133 has the same shape or size as the first protrusion 132 for enhancing precise mechanical docking.

[0049] Please refer to Figure 7 In some specific embodiments, the base 131 has a first end 135, a second end 137 and a middle end 136; specifically, the base 131 has a first end 135, a second end 137 and a middle end 136 located between the first end 135 and the second end 137; the first protrusion 132 is arranged between the first end 135 and the middle end 136; specifically, the first protrusion 132 is arranged between the first end 135 and the middle end 136 of the base 131, rather than directly at the first end 135, so that the first protrusion 132 can enter the slot 129 of the upper combination plate 11 more conveniently and accurately, thereby effectively improving the speed and accuracy of assembly. The second protrusion 133 is arranged between the second end 137 and the middle end 136; similarly, the second protrusion 133 is arranged between the second end 137 and the middle end 136 of the base 131, rather than directly at the second end 137, and the second protrusion 133 is also precisely docked with the first protrusion 132 to enhance the alignment accuracy of the prefabricated combination pin plate 10 used for capacitor production.

[0050] Please refer to Figure 1 to Figure 2 In some specific embodiments, a plurality of positioning holes 134 are provided on the first side 16 and the second side 17. Specifically, the main function of the positioning holes 134 is to ensure the accurate placement and fixation of the pin plate by being sleeved on the positioning holes 134 of the production equipment during the capacitor production process. This arrangement helps to reduce human operation errors and improve the repetitive accuracy and efficiency of assembly. Through the positioning holes 134 on the first side 16 and the second side 17, it is easier to achieve accurate alignment of the upper assembly plate 11 and the lower assembly plate 12. While the positioning holes 134 are sleeved on the positioning holes 134 of the production equipment, it also ensures that when the upper assembly plate 11 and the lower assembly plate 12 are combined, all the slots 129 and the tenons 130 can be correctly docked, further improving the alignment accuracy of the prefabricated assembly pin plate 10 used for capacitor production.

[0051] Please refer to Figures 8 to 10 , the upper assembly board 11 further includes a plurality of upper beams 116, and the lower assembly board 12 further includes a plurality of lower beams 126; in some specific embodiments, both ends of the plurality of upper beams 116 are connected to the two first side edges 16, and both ends of the plurality of lower beams 126 are connected to the two second side edges 17. Specifically, due to the fixed connection between the upper beams 116 and the first side edges 16, and the fixed connection between the lower beams 126 and the second side edges 17, the upper beams 116 and the lower beams 126 ensure that when the prefabricated assembly pin board 10 for capacitor production is assembled, the upper pins 111 and the lower pins 121 can be correctly aligned, further improving assembly efficiency and product quality.

[0052] Please continue to refer to Figures 8 to 10 In some specific embodiments, the upper pins 111 include an upper bending portion 112 and an upper fixing portion 113; the upper contact portion 114, the upper bending portion 112 and the upper fixing portion 113 are sequentially connected. Specifically, the upper contact portion 114 is located at one end of the upper pin 111, directly in contact with the upper end of the capacitor 13, to ensure good electrical connection. The upper bending portion 112 connects the upper contact portion 114 and the upper fixing portion 113, and the upper bending portion 112 is configured to have a certain bending angle, which helps to absorb and disperse the mechanical stress that may be generated on the connection point during production and use. At the same time, the bending structure of the upper bending portion 112 makes the upper contact portion 114 and the upper fixing portion 113 in different planes, which facilitates the installation of the capacitor 13 below the upper contact portion 114. The upper fixing portion 113 is used to fix the upper pin 111 on the upper assembly board 11 to ensure that the position of the lower pin 121 is stable during the entire production and application period.

[0053] The plurality of lower pins 121 include a lower bending portion 122 and a lower fixing portion 123; the lower contact portion 124, the lower bending portion 122 and the lower fixing portion 123 are sequentially connected and arranged. Specifically, the lower contact portion 124 is located at one end of the lower pin 121, and directly contacts the lower end of the capacitor body 13, so as to ensure a good electrical connection. The lower bending portion 122 connects the lower contact portion 124 and the lower fixing portion 123, and the lower bending portion 122 is configured to have a structure with a certain bending angle, which helps to absorb and disperse the mechanical stress that may be generated on the connection point of the capacitor body during production and use. At the same time, the bending structure of the lower bending portion 122 makes the lower contact portion 124 and the lower fixing portion 123 in different planes, so as to facilitate the installation of the capacitor body 13 above the lower contact portion 124. The lower fixing portion 123 is used to fix the lower pin 121 on the upper assembly board 11, so as to ensure the stability of the position of the lower pin 121 during the entire production and application period.

[0054] See also Fig. 9In some specific embodiments, the upper bending portion 112 and the lower bending portion 122 are both configured to be arched; specifically, the arched configuration improves the elasticity and load-bearing capacity of the upper bending portion 112 and the lower bending portion 122, and the arched structure helps to more effectively disperse and absorb the mechanical stress that may be generated during the production and use of the capacitor, thereby protecting the capacitor body 13 from damage. At the same time, the arched upper bending portion 112 and the lower bending portion 122 provide a storage space between the upper contact portion 114 and the lower contact portion 124, and the capacitor body 13 is disposed in the storage space; specifically, the capacitor body 13 is precisely placed in the storage space to ensure that the capacitor body 13 is fixed and protected during the production process. The existence of the storage space ensures that the upper contact portion 114 and the lower contact portion 124 will not cause direct mechanical pressure on the capacitor body 13, thereby reducing the risk of damage. The width of the upper bending portion 112 is smaller than the width of the upper contact portion 114 and the upper fixing portion 113, and the width of the lower bending portion 122 is smaller than the width of the lower contact portion 124 and the lower fixing portion 123, so as to allow the upper bending portion 112 and the lower bending portion 122 to have a better elastic response when subjected to external force during production without affecting the stability of the overall connection and the efficiency of the electrical connection.

[0055] Please continue to refer to Figures 8 to 9 In some specific embodiments, the upper bending portion 112 is provided with a first upper hollow hole 115 at one end thereof facing the upper contact portion 114; specifically, the first upper hollow hole 115 is provided mainly to reduce the weight of the overall structure and to improve the elasticity of the pin portion, so that the upper pin 111 can provide better bending and buffering capabilities when subjected to mechanical stress during the production process. The lower bending portion 122 is provided with a first lower hollow hole 125 at one end thereof facing the lower contact portion 124; similarly, the first upper hollow hole 115 is provided mainly to reduce the weight of the overall structure and to improve the elasticity of the lower pin 121, so that the lower pin 121 can provide better bending and buffering capabilities when subjected to mechanical stress during the production process.

[0056] Please continue to refer to Figures 8 to 9 In some specific embodiments, the upper fixing portion 113 is connected to the upper beam 116; specifically, the upper beam 116 is used to provide structural support and stability. The upper beam 116 not only enhances the overall strength of the upper assembly board 11, but also provides a support point for fixing the upper pins 111. The lower fixing portion 123 is connected to the lower beam 126. Similarly, the lower beam 126 is used to provide structural support and stability. The lower beam 126 not only enhances the overall strength of the lower assembly board 12, but also provides a support point for fixing the lower pins 121.

[0057] Please continue to refer to Figures 8 to 9In some specific embodiments, a plurality of the upper fixing parts 113 are provided with a second upper hollow hole 117; specifically, the second upper hollow hole 117 is provided so that the heat energy is more evenly distributed when welding the capacitor, reducing the concentration of thermal stress and avoiding overheating and deformation of the material. The second upper hollow hole 117 is located at one end of the upper fixing part 113 facing the upper beam 116; specifically, the capacitor is cut and stamped from a prefabricated combined pin plate 10 for capacitor production, and the cutting position is the intersection of the second upper hollow hole 117 and the upper beam 116, so the cut capacitor pin has a second upper hollow hole 117. A plurality of the lower fixing parts 123 are provided with a second lower hollow hole 127; specifically, the second lower hollow hole 127 is provided so that the heat energy is more evenly distributed when welding the capacitor, reducing the concentration of thermal stress and avoiding overheating and deformation of the material. The second lower hollow hole 127 is located at one end of the lower fixing portion 123 toward the lower beam 126; specifically, the capacitor is cut and punched from a prefabricated combined pin plate 10 used for capacitor production, and the cutting position is the intersection of the second lower hollow hole 127 and the lower beam 126, so the cut capacitor pin has the second lower hollow hole 127.

[0058] During welding, the second upper hollow hole 117 and the second lower hollow hole 127 facilitate the flow and filling of solder, ensuring the strength and stability of the solder joint throughout the entire service life. It helps to disperse the heat during the welding process and reduce the risk of material stress and deformation caused by high temperature. At the same time, by reducing the use of materials, not only the cost is saved, but also the weight of the prefabricated combination pin board used for capacitor production is reduced, which helps to improve operating efficiency and reduce energy consumption.

[0059] Please continue to refer to Figures 8 to 9 In some specific embodiments, the second upper hollow hole 117 and the second lower hollow hole 127 are both set to a square shape, and the four corners of the square are provided with chamfers; the chamfers are curved chamfers. Specifically, the chamfers are to reduce stress concentration that may be generated during welding, thereby preventing the generation of cracks, thereby improving the welding stability of the capacitor. The curved chamfers help to more evenly disperse the stress caused by thermal expansion or other physical forces in the structure, especially during welding and processing, thereby significantly reducing the risk of structural failure.

[0060] Please continue to refer to Figures 8 to 9 In some specific implementations, a plurality of the upper beams 116 are provided with a plurality of third upper hollow holes 118; a plurality of the lower beams 126 are provided with a plurality of third lower hollow holes 128. The third upper hollow holes 118 and the third lower hollow holes 128 are used to reduce the weight of the upper assembly plate 11 and the lower assembly plate 12, improve the use efficiency of the material, and provide positioning during the production process.

[0061] Please continue to refer to Figures 8 to 9 In some specific embodiments, several of the upper contact portions 114 and several of the lower contact portions 124 are provided with several welding bumps 15. Specifically, the bumps can be set as small dots or small cylinders, formed by the lower convexity of the upper contact portion 114 and the upper convexity of the upper contact portion 114. The welding bumps 15 are used to provide enhanced welding contact points, so that the capacitor body 13 can form a more uniform and stable welding bond around the contact points. This helps to improve the mechanical strength and electrical performance of the welding, and ensure a good electrical connection between the capacitor body 13 and the pins.

[0062] In the second embodiment of the present application, a capacitor is provided, which is produced by the prefabricated combination pin plate 10 for capacitor production as described above. It can be seen that the capacitor has the advantages of high performance consistency and high reliability.

[0063] In summary, the present application provides a prefabricated combination pin plate and capacitor for capacitor production, and the prefabricated combination pin plate for capacitor production includes: an upper combination plate, the upper combination plate includes two first sides; a lower combination plate, the lower combination plate includes two second sides; a plurality of slots are provided on the first side; a plurality of tenons are provided on the second side; when the upper combination plate and the lower combination plate are combined together, the plurality of tenons are arranged in a one-to-one correspondence in the plurality of slots.
