Description

Technical Field

[0001] The utility model relates to the electronic field, in particular to a wiring protection capacitor. Background Art

[0002] Two conductors close to each other, with a non-conductive insulating medium in between, form a capacitor. When a voltage is applied between the two plates of a capacitor, the capacitor will store charge. The capacitance of a capacitor is numerically equal to the ratio of the charge on one conductive plate to the voltage between the two plates. The basic unit of the capacitance of a capacitor is farad (F). In circuit diagrams, the letter C is usually used to represent a capacitor element.

[0003] The existing patent (Announcement No.: CN220232934U) discloses "a wiring protection type capacitor, including a capacitor body, and also including an upper cover plate and a lower cover plate, the upper cover plate and the lower cover plate are respectively sleeved on the upper and lower outer walls of the capacitor body, and the upper cover plate and the lower cover plate are connected by a limiting mechanism; the limiting mechanism includes a card block fixed to the bottom of the upper cover plate, a card slot opened at the top of the lower cover plate and corresponding to the card block, and a positioning block fixed to the outer wall of the card block. The wiring protection type capacitor is used in combination with an upper cover plate, a lower cover plate and a limiting mechanism. The upper cover plate and the lower cover plate can be disassembled and separated in opposite directions, which can facilitate comprehensive protection of the capacitor. At the same time, it is more convenient when disassembly and maintenance are required. The card block is inserted into the card slot, which can be used for positioning effect, and the upper cover plate and the lower cover plate are conveniently locked with the cooperation of the moving rack and the limiting slot, so as to achieve a relatively stable limiting purpose and enhance the stability of the equipment."

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. When installing the outer shell, the device needs to operate the two limit mechanisms on both sides successively, and the installation and disassembly are not simplified enough; 2. In this device, only the outer shell can fix the capacitor, and there are fewer fixing elements, which may lead to a decrease in the fixing effect.

[0005] Therefore, the utility model provides a wiring protection capacitor to solve the problems raised in the above background technology. Utility Model Content

[0020] Furthermore, spring handles are rotatably provided on both sides of the upper end of the inner shell, and the pins on the upper end of the capacitor body penetrate the upper end of the first main body through the mounting hole;

[0021] Through the above technical solution, the spring handle facilitates the removal of the inner shell, and the mounting hole facilitates the pins to extend out of the protective shell, which facilitates wiring work and ensures that the capacitor body will not rotate in the protective shell.

[0022] The utility model has the following beneficial effects:
