[0002] A capacitor, abbreviated as capacitance and represented by the letter C, is a device that can hold electric charges and is also a main component of an electronic circuit. A capacitor is composed of two conductors close to each other with a layer of non-conductive insulating medium in between. It can store electrical energy and has the characteristics of charging, discharging, passing alternating current, and blocking direct current. The overall structure of the capacitor is cylindrical. However, the electrodes of the existing capacitors cannot be disassembled. When the electrodes are damaged, the entire capacitor cannot be reused. The prior art proposes a clamping structure that cooperates a bolt with a bushing. A radial hole is opened along the side of the bushing, and the pin to be connected is radially inserted into the hole from the side.

Although this method can achieve the purpose of changing and replacing the pins, it will limit the PCB design and requires more space to place the capacitor, causing problems for the installation of the capacitor.
