[0002] In existing technologies, it is often necessary to connect multiple capacitors in parallel with copper wires to form a parallel capacitor bank, and then connect multiple parallel capacitor banks in series with copper wires. Because the cross-sectional area of ​​copper wires is very large, a lot of solder material is required when connecting them to the end face of the capacitor core. Moreover, when a single capacitor is damaged, the entire capacitor bank is usually removed and replaced, which is time-consuming, labor-intensive, and wasteful of resources. Summary of the Invention

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Reference Figure 1 and Figure 2 The present invention proposes a series-parallel capacitor bank support, comprising: multiple parallel capacitor bank supports and multiple connectors 6;

[0034] Multiple parallel capacitor bank brackets are arranged sequentially, and each parallel capacitor bank bracket includes a first connection terminal 12 and a second connection terminal 21 for connecting in parallel with multiple capacitors 3 mounted on the parallel capacitor bank bracket;

[0035] Each connector 6 connects between two adjacent parallel capacitor bank supports;

[0036] Each connector 6 includes a third connection terminal and a fourth connection terminal. The third connection terminal is plugged into the first connection terminal 12 of the previous parallel capacitor bank bracket in a plug-and-play manner, and the fourth connection terminal is plugged into and fixed to the second connection terminal 21 of the adjacent next parallel capacitor bank bracket in a plug-and-play manner.

[0037] This invention uses connector 6 to quickly connect multiple parallel capacitor groups mounted on multiple parallel capacitor brackets 3 in series, eliminating the need for copper wire soldering, saving solder, and making it very convenient to disassemble and replace capacitors.

[0038] Reference Figure 3-7 In this embodiment, the parallel capacitor bank support includes a housing box 1 and a connecting plate 2 for accommodating multiple capacitors 3 sequentially along the length direction.

[0039] The connecting plate 2 has a first end and a second end opposite to each other in its length direction. The bottom of the connecting plate 2 is provided with a first receiving groove 22 for accommodating the top electrode post of each capacitor 3 along its length direction. The first end is provided with a clearance opening 23 that allows the electrode post of the capacitor 3 to slide into the first receiving groove 22 along the length direction of the connecting plate 2. Each capacitor 3 is provided with a conductive contact piece 24 for conductive contact with the top electrode post of the capacitor 3 in the first receiving groove 22. The second connecting terminal 21 is provided on the second end and is electrically connected to a plurality of second conductive contact pieces 24 respectively.

[0040] The receiving box 1 has a first sidewall and a second sidewall opposite to each other in its length direction. The top of the first sidewall has a through hole 13 for the first end of the connecting plate 2 to pass through. The second sidewall has an insertion hole 14 for inserting into the first end of the connecting plate 2 at the corresponding position of the through hole 13. The bottom of the receiving box 1 has a second receiving groove 11 for accommodating the bottom electrode post of the corresponding capacitor 3 at the corresponding position. The second receiving groove 11 is provided with an elastic conductive contact component 5 for conductive contact with the bottom electrode post of the capacitor 3. The first connecting terminal 12 is disposed at the bottom of the first sidewall and is electrically connected to each elastic conductive contact component 5 respectively.

[0041] When the first end of the connecting plate 2 passes through the through hole 13 and is inserted into the insertion hole 14, the conductive contact piece 24 is used to make contact with the top electrode post of the corresponding capacitor 3, and the elastic conductive contact assembly 5 is used to make contact with the bottom electrode post of the corresponding capacitor 3.

[0042] This configuration allows multiple capacitors 3 to be fixed inside the housing box 1. The first receiving groove 22 on the connecting plate 2 and the second receiving groove 11 at the bottom of the housing box 1 can limit the electrode posts of the capacitors 3, ensuring that the capacitors 3 are placed vertically. This ensures that the bottom electrode post of the capacitors 3 is connected to the elastic conductive contact component 5 and the top electrode post of the capacitors 3 is connected to the conductive contact piece 24. This allows for the rapid parallel connection of multiple capacitors 3 without the need for copper wire welding, making assembly convenient and saving solder material. It is also suitable for parallel connection of different numbers of capacitors 3 and easy to disassemble.

[0043] In order to achieve elastic conductive contact with the bottom electrode post of capacitor 3, in one specific embodiment, the elastic conductive contact assembly 5 includes a conductive contact seat 51, a spring 53 and a guide post 52.

[0044] The conductive contact seat 51 is slidably disposed in the second receiving groove 11 in the vertical direction, and a third receiving groove matching the guide post 52 is opened at the bottom of the conductive contact seat 51.

[0045] The guide post 52 is disposed at the bottom of the second receiving groove 11, the top end of the guide post 52 extends into the third receiving groove and is slidably connected to the conductive contact seat 51, and the conductive contact seat 51 is electrically connected to the guide post 52, and the bottom end of the guide post 52 is electrically connected to the first connecting terminal 12 through a wire.

[0046] Spring 53 is sleeved on guide post 52. One end of spring 53 is fixedly connected to conductive contact seat 51, and the other end is fixedly connected to the bottom of second receiving groove 11.

[0047] In a further embodiment, the conductive contact seat 51 is provided with a first limiting part, and the opening of the second receiving groove 11 is provided with a second limiting part for limiting the first limiting part from dislodging from the second receiving groove 11. The first limiting part and the second limiting part cooperate to limit the conductive contact seat 51 from dislodging from the second receiving groove 11, so as to improve the reliability of the elastic conductive contact assembly 5.

[0048] In a further embodiment, the top end of the guide post 52 is provided with a third limiting part, and the opening of the third receiving groove is provided with a fourth limiting part for restricting the third limiting part from falling out of the third receiving groove. The third limiting part and the fourth limiting part cooperate to restrict the guide post 52 from falling out of the third receiving groove, so as to further improve the reliability of the elastic conductive contact assembly 5.

[0049] In another specific embodiment, the elastic conductive contact assembly 5 includes a conductive spring, the bottom end of which is fixedly connected to the bottom of the second receiving groove 11, and the conductive spring is electrically connected to the first connecting terminal 12 via a wire.

[0050] Of course, those skilled in the art are capable of integrating each guide post 52 or conductive spring into the same conductive element or wire for electrical connection with the first connection terminal 12.

[0051] In this embodiment, a cover plate is also included, which is detachably connected to the receiving box 1.

[0052] When the cover plate is closed with the receiving box 1, the bottom surface of the cover plate contacts the top surface of the connecting plate 2.

[0053] This configuration improves the protection of multiple capacitors 3 and also allows for the simultaneous pressing of the connecting plate 2, ensuring that the conductive contact piece 24 on the connecting plate 2 is in contact with the top electrode post of the corresponding capacitor 3.

[0054] To enhance the connection strength between the connecting plate 2 and the receiving box 1, this embodiment also includes a bolt 4. A screw hole matching the bolt 4 is provided at the top of the first side wall. The bottom end of the screw hole communicates with the through hole 13. The bottom end of the bolt 4 passes through the screw hole, enters the through hole 13, and is pressed onto the connecting plate 2.

[0055] In a further embodiment, when a cover plate is present, the screw hole is a countersunk hole, thereby avoiding any impact on the sealing of the cover plate and the container.

[0056] In this embodiment, the receiving box 1 is provided with multiple partitions evenly and at intervals along its length direction. The partitions divide the receiving box 1 into multiple receiving cavities. Multiple capacitors 3 are placed in the multiple receiving cavities in a one-to-one correspondence. The side of the partitions near the capacitors 3 is provided with an arc-shaped contact surface for abutting against the capacitors 3.

[0057] This configuration allows for the repositioning of each capacitor 3, ensuring its vertical placement and thus guaranteeing contact between the capacitor 3 and the conductive contact piece 24 and the elastic conductive contact assembly 5. It also avoids interference caused by collisions between adjacent capacitors 3.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
