A multi-core capacitor connection structure for uneven distribution of electrode terminals

Abstract

A multi-core capacitor connection structure for unevenly distributed electrode terminals, comprising a shell, a multi-core capacitor, a bus bar, two bus bars, an adapter group, and a plurality of electrode terminals connected to the adapter group. The bus bars are spaced apart and connected to the bus bar respectively. The adapter group comprises a first adapter, a second adapter, and a third adapter. The distances between the first adapter, the second adapter, and the third adapter and the bus bars are equal, and the resistances of the first adapter, the second adapter, and the third adapter are equal. Even if the electrode terminals are unevenly distributed, the currents flowing through the respective corresponding electrode terminals can be equalized by the first adapter, the second adapter, and the third adapter respectively, so that the current flowing through a certain electrode terminal is not too large, thereby preventing damage to the electrode terminal.

Description

Technical Field

[0001] This invention belongs to the field of capacitor manufacturing technology, and in particular to a connection structure for multi-core capacitors with unevenly distributed electrode terminals. Background Technology

[0002] A capacitor is formed by two conductors placed close together with a non-conductive insulating medium sandwiched in between. With the rapid development of electronic information technology and the increasingly fast pace of digital electronic product upgrades, the production and sales of consumer electronics, primarily flat-screen TVs, laptops, and digital cameras, have continued to grow, driving significant growth in the capacitor industry.

[0003] As in the utility model patent with publication number CN219403486U, the electrode terminals are evenly distributed on the outer casing, and copper busbars are vertically connected to the electrode terminals, thereby ensuring that the current passing through each electrode terminal is evenly distributed. However, in actual production, due to certain practical needs, the electrode terminals are not necessarily evenly distributed on the outer casing; some electrode terminals may be located on the same side of the outer casing. In this case, if a traditional vertical connection structure is used, the current distribution flowing through the electrode terminals will be uneven, easily leading to excessive current flowing through some electrode terminals, causing excessive heat generation at those electrode terminals, and ultimately damaging the electrode terminals. Summary of the Invention

[0004] In view of this, the present invention provides a connection structure for multi-core capacitors with unevenly distributed electrode terminals to solve the above problems.

[0005] A connection structure for a multi-core capacitor with unevenly distributed electrode terminals includes a housing, a set of multi-core capacitors housed within the housing, a set of current-conducting busbars connected to the multi-core capacitors and used to guide the current generated by the multi-core capacitors, two busbars connected to the current-conducting busbars and used to collect the current guided by the current-conducting busbars, a set of adapter groups connected to the busbars and used to collect the current on the busbars to the electrode terminals, and a plurality of electrode terminals connected to the adapter groups. The multi-core capacitors include a plurality of core groups connected in parallel, each core group consisting of a plurality of capacitors arranged at intervals according to the direction of current flow. Two of the current-conducting busbars are disposed opposite to each other. The adapter groups include a first adapter, a second adapter spaced apart from the first adapter, and a third adapter spaced apart from the second adapter. The first adapter, the second adapter, and the third adapter are connected at equal intervals at one end to the equal distribution point of the busbar, and their other ends are connected to their respective corresponding electrode terminals. The resistances of the first adapter, the second adapter, and the third adapter are equal.

[0006] Furthermore, the current guide includes a positive current guide group connected to the positive terminal of the capacitor, and a negative current guide group connected to the negative terminal of the capacitor.

[0007] Furthermore, the positive electrode current guide group includes a plurality of positive electrode current guides connected to the positive electrode of the capacitor, and the negative electrode current guide group includes a plurality of negative electrode current guides connected to the negative electrode of the capacitor.

[0008] Furthermore, the number of positive electrode current guides is equal to the number of core groups, and the positive electrode current guides are L-shaped.

[0009] Furthermore, one end of the manifold is connected to the flow guide, and the other end is connected to the adapter assembly.

[0010] Furthermore, the first adapter, the second adapter, and the third adapter are made of copper.

[0011] Furthermore, the adapter assembly is located between the busbar and the electrode terminal.

[0012] Furthermore, the electrode terminals are fixedly connected to the housing.

[0013] Furthermore, the two busbars are respectively connected to the positive electrode conductor and the negative electrode conductor.

[0014] Furthermore, the housing is made of stainless steel.

[0015] Compared with existing technologies, the multi-core capacitor connection structure for unevenly distributed electrode terminals provided by this utility model connects the first adapter, the second adapter, and the third adapter in the adapter group to the busbar at equal intervals. By controlling the different stacking numbers of the first adapter, the second adapter, and the third adapter, the resistance of the three is ensured to be equal. This ensures that the current flowing through each electrode terminal is equal even when the electrode terminals are unevenly distributed. It also prevents excessive current flowing through any electrode terminal, which could lead to excessive heat generation and thus affect the service life of that electrode terminal.

[0020] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0021] like Figures 1 to 4 The diagram shows a structural schematic of a multi-core capacitor connection structure for unevenly distributed electrode terminals provided by this utility model. The multi-core capacitor connection structure for unevenly distributed electrode terminals includes a housing 10, a set of multi-core capacitors 20 housed within the housing 10, a set of current-conducting busbars 30 connected to the multi-core capacitors 20, two current-conducting components 40 connected to the current-conducting busbars 30, a set of adapter groups 50 connected to the current-conducting components 40, and multiple electrode terminals 60 connected to the adapter groups 50. The multi-core capacitor connection structure for unevenly distributed electrode terminals also includes other functional modules, such as an assembly module and a heat dissipation module, etc., which should be known to those skilled in the art and will not be described in detail here.

[0022] It is not difficult to imagine that the multi-core capacitor connection structure for unevenly distributed electrode terminals also has an external load. A load refers to a device that converts electrical energy into other forms of energy, such as a light bulb, motor, or electric furnace, which is well known to those skilled in the art. In this invention, the load is used to connect with the multi-core capacitor connection structure for unevenly distributed electrode terminals to form a closed loop.

[0023] The housing 10 is used to house the multi-core capacitor 20, the current bus 30, the busbar 40, the adapter 50, and the electrode terminals 60. The housing 10 may be made of stainless steel, thereby providing better stability and protection for the capacitor 211 located within the housing 10.

[0024] The multi-core capacitor 20 includes multiple core groups 21 connected in parallel. Each core group 21 has the same structure. The number of core groups 21 can be set according to actual needs; in this embodiment, the number of core groups 21 is eight.

[0025] Each core assembly 21 includes multiple capacitors 211 connected in series in multiple rows and columns. The capacitors 211 are used to store electrical energy and are existing technology, so they will not be described in detail here. In this embodiment, the core assembly 21 is composed of six rows and two columns of capacitors 211 connected in series in a sequentially spaced manner.

[0026] like Figure 2 As shown, the current-carrying bus 30 is used to connect multiple capacitors 211 in series to form a group, and together discharge to the outside or charge the core group 21. The current-carrying bus 30 includes a positive current-carrying group 31 connected to the positive terminal of the capacitor 211, and a negative current-carrying group 32 connected to the negative terminal of the capacitor 211.

[0027] The positive electrode current guide group 31 includes a plurality of positive electrode current guides 311 connected to the positive electrode of the capacitor 211. The number of positive electrode current guides 311 is equal to the number of core groups 21. In this embodiment, the number of positive electrode current guides 311 is eight. The length of the positive electrode current guide 311 is determined by the number of rows of capacitors 211 in the core group 21. In this embodiment, the number of rows of capacitors 211 is six. The positive electrode current guide 311 can be L-shaped, so that the positive electrode current guide 311 has a bent portion facing the busbar 40. This bent portion is used for welding to the busbar 40 for fixed connection. The structure of the positive electrode current guide group 31 itself is prior art. The positive electrode connection group therein has been described in the utility model patent with publication number CN230085854U, and will not be repeated here.

[0028] The negative electrode current-conducting group 32 has the same structure and working principle as the positive electrode current-conducting group 31, and the structure of the negative electrode current-conducting group 32 will not be described in detail here. However, in order to more clearly illustrate the invention, only the composition of the negative electrode current-conducting group 32 is listed, that is, the negative electrode current-conducting group 32 includes a plurality of negative electrode current-conducting elements 321 connected to the negative electrode of the capacitor 211.

[0029] like Figure 3 As shown, the two busbars 40 are spaced apart and connected to the positive current-conducting group 31 and the negative current-conducting group 32, respectively. The busbars 40 are used to guide the current discharged from the current-conducting group 30 to the adapter group 50. The length of the busbar 40 is determined by the number of columns of the capacitors 211 in the multi-core capacitor 20. In this embodiment, the number of columns of the capacitors 211 is sixteen.

[0030] The adapter assembly 50 connects the busbar 40 and the electrode terminals 60. The adapter assembly 50 includes multiple adapters, the number of which is equal to the number of electrode terminals 60. The connection points between the multiple adapters and the busbar 40 are equally spaced. In this embodiment, there are three adapters, each connected to one of the three equal division points of the busbar 40. That is, the adapter assembly 50 includes a first adapter 51, a second adapter 52 spaced apart from the first adapter 51, and a third adapter 53 spaced apart from the second adapter 52.

[0031] Because the electrode terminals 60 are fixedly mounted on one side of the housing 10 due to actual production needs, the electrode terminals 60 are not evenly distributed on the housing 10. Furthermore, the connection points between the adapter and the busbar 40 are equally spaced, and the adapter is tilted at a certain angle during the connection between the busbar 40 and the electrode terminals 60. The first adapter 51, the second adapter 52, and the third adapter 53 are arranged at equal intervals, with the first adapter 51 closer to the electrode terminals 60. The lengths of the first adapter 51, the second adapter 52, and the third adapter 53 are different. Specifically, the length of the second adapter 52 is twice the length of the first adapter 51, and the length of the third adapter 53 is twice the length of the first adapter 51.

[0032] Since the lengths of the first adapter 51, the second adapter 52, and the third adapter 53 are different, to ensure that the resistance flowing through them is equal and the current flowing through each of the electrode terminals 60 is equal, the thickness of the three adapters can be controlled to ensure that the resistances of the three adapters are equal. Specifically, the thickness of the three adapters can be controlled by stacking different numbers of the first adapter 51, the second adapter 52, and the third adapter 53. The first adapter 51, the second adapter 52, and the third adapter 53 are equal in thickness and material, except for their lengths. In this invention, one first adapter 51 is stacked, two second adapters 52 are stacked, and three third adapters 53 are stacked to control the resistances of the three adapters to be equal. The above is only one embodiment of the present utility model. The adapter group 50 can also be provided with a fourth adapter, a fifth adapter, etc., according to actual needs. It is only necessary to ensure that the connection part of the adapter and the busbar 40 are located at the even distribution point and that the resistance of the multiple adapters is ultimately equal according to the corresponding length ratio and stacked in different quantities, so as to ensure that the current flowing through each of the adapters and each of the electrode terminals 60 is equal.

[0033] like Figure 4 As shown, the electrode terminal 60 is connected and fixed to the housing 10. The electrode terminal 60 serves as a lead-out terminal, primarily used for transmitting electrical signals or conducting electricity; this is a fact well-known to those skilled in the art. The number of electrode terminals 60 can be determined according to actual needs; in this embodiment, there are three electrode terminals 60. Conventionally, the electrode terminals 60 are generally evenly distributed on the housing 10, but for practical needs, the electrode terminals 60 can also be individually disposed on one side of the housing 10. In this invention, the electrode terminal 60 is disposed on one side of the housing 10.

[0034] During use, such as during discharge, electrons transfer from the negative electrode of the core assembly 21 to the positive electrode to form a current. Then, the current flows into the busbar 40 through the negative electrode conductor 321, and successively flows through the adapter 50 connected to the busbar 40 and the electrode terminal 60. After passing through the load (not shown), the current flows into the adapter 50 connected to the electrode terminal 60 and the busbar 40, and then flows into the positive electrode of the core assembly 21 through the positive electrode conductor 311, thus forming a closed loop.

[0035] It should be noted that when current flows through the electrode terminals 60, the current on the core assembly 21 passes through the current busbar 30 and is split into currents flowing into the busbar 40 by the adapter group 50, thereby ensuring that the current flowing through each electrode terminal 60 is equal. By connecting each adapter group 50 at equal intervals to the busbar 30 and controlling the number of stacked adapter groups 50, the resistance between each adapter group 50 is made equal, thus ensuring that the current flowing through the electrode terminals 60 is equal. This evenly distributes the current flowing out of the multi-core capacitor 20, preventing excessive current intensity flowing through any electrode terminal 60 and affecting its service life.

[0036] Compared with the prior art, the multi-core capacitor connection structure for unevenly distributed electrode terminals provided by this utility model connects the first adapter 51, the second adapter 52, and the third adapter 53 in the adapter group 50 at equal intervals to the busbar 30. By controlling the different stacking numbers of the first adapter 51, the second adapter 52, and the third adapter 53, the resistance among the three is ensured to be equal. This ensures that the current flowing through each of the electrode terminals 60 is equal even when the electrode terminals 60 are unevenly distributed. It prevents excessive current flowing through any one electrode terminal 60, which could lead to excessive heat generation and thus affect the service life of that electrode terminal 60.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
