Description

A capacitor protection and fixing device

Technical field

The invention belongs to the technical field of capacitors, specifically a capacitor protection and fixing device.

Background technique

A capacitor is two conductors close to each other with a layer of non-conductive insulating medium sandwiched between them, which constitutes a capacitor. A capacitor stores charge when a voltage is applied between its two plates. The capacitance of a capacitor is numerically equal to the ratio of the amount of charge on one conducting plate to the voltage between the two plates. Capacitors play an important role in tuning, bypass, coupling, filtering and other circuits. Capacitors are widely used in various circuits. They are common electronic components in circuits and play a vital role in circuits.

Conventional small capacitors are generally soldered between the bottom pins and the circuit, and there is a certain distance between the bottom end of the capacitor and the circuit to ensure insulation, while larger capacitors are generally soldered between the mounting bracket and the circuit. Connection, that is, first connect the bottom end of the capacitor to the installation, then connect the installation bracket to the ground, and finally connect the circuit. This kind of installation bracket needs to be customized with the corresponding bracket to complete the stable installation of the capacitor. After replacement When installing a capacitor, you need to find a matching mounting bracket, which has poor versatility. At the same time, when the capacitor is damaged or bursts, it is easy to cause damage to the mounting bracket, thereby causing irreversible damage to the overall circuit.

Common capacitors will store a certain amount of charge when working, which will inevitably cause the temperature of the capacitor to rise. Small capacitors generate less heat and are usually installed in an exposed design, while large capacitors are larger in size and generate less heat. It is also larger and usually installed with a mounting bracket. The part connecting the capacitor and the mounting bracket is not exposed. The heat cannot be completely dissipated due to the relative sealing here, which ultimately leads to the problem of poor heat dissipation in the capacitor, making it easy to work on the capacitor. cause greater impact.
