[0002] A through-hole capacitor is a three-terminal capacitor. Compared with ordinary capacitors, a through-hole capacitor can be directly installed on a circuit board, and the influence of lead inductance is almost eliminated. Currently, the through-hole capacitors usually adopt the traditional wiring method of in-and-out leads for installation. When multiple groups of through-hole capacitors need to be connected, multiple groups of in-and-out leads are required for installation, resulting in excessive wiring inside the installation cabinet. On the one hand, the installation is cumbersome, leading to an increase in installation time cost; on the other hand, too much wiring occupies the cabinet space, causing the internal space of the cabinet to be tense and inconvenient for the installation of other devices.

[0020] As can be seen from the background art, when multiple feedthrough capacitors are currently installed, the wiring method of incoming and outgoing lines is usually adopted for installation. It is necessary to use wires to connect the motors at both ends of the feedthrough capacitors, and then connect the feedthrough capacitors to the external circuit through wires. When multiple feedthrough capacitors need to be connected and installed, the installation and placement are carried out by wiring. Due to the large number and complexity of the incoming and outgoing lines, the installation is cumbersome and inconvenient. Moreover, too many wirings will occupy the space inside the installation cabinet, causing inconvenience to the installation of other devices, and it is necessary to replace a larger installation cabinet to meet the space requirements for use, resulting in an increase in cost.

[0021] To solve the above problems, an embodiment of the present invention provides a feedthrough capacitor group, which includes a plurality of feedthrough capacitors and an electrical connection board. The electrical connection board is electrically connected to each feedthrough capacitor respectively, and the electrical connection board connects the plurality of feedthrough capacitors in parallel. The connection between the plurality of feedthrough capacitors is realized through the electrical connection board, and there is no need to adopt the incoming and outgoing line method for connection and installation. The installation structure is simple, the installation is convenient, and the occupied installation space is small, which is beneficial to reducing costs.

[0028] In this embodiment, each of the feedthrough capacitors 100 extends along a first direction X, which is the extending direction from the second end 104 to the first end 103. The first electrical connection plate 201 and the second electrical connection plate 202 are arranged perpendicular to the first direction X.

[0029] In this embodiment, a plurality of first holes 203 are provided on the first electrical connection plate 201. The first holes 203 are adapted to the first end 103 of the feedthrough capacitor 100, and the first end 103 penetrates through the first holes 203.

[0030] The number of the first holes 203 and their positions on the first electrical connection plate 201 can be determined according to the number and positions of the feedthrough capacitors 100 in actual use.

[0031] In this embodiment, the number of the first holes 203 is equal to the number of the feedthrough capacitors 100 to be installed; in other embodiments, the number of the first holes 203 can also be greater than the number of the feedthrough capacitors 100 to be installed.

[0032] Similarly, in this embodiment, a plurality of second holes 204 are provided on the second electrical connection plate 202. The second holes 204 are adapted to the second end 104 of the feedthrough capacitor 100, and the second end 104 penetrates through the second holes 204.

[0040] In this embodiment, the first fastening bolt 205 is connected to the first electrical connection plate 201 and the second electrical connection plate 202 by welding. Welding can make the connection between the first fastening bolt 205 and the first electrical connection plate 201 and the second electrical connection plate 202 more firm, so that the connection between the feedthrough capacitor 100 and the first electrical connection plate 201 and the second electrical connection plate 202 is more firm.
