Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of capacitors, in particular to a common compensation capacitor with an elastic inner shell. Background Art
[0002] As an indispensable key component in power electronic equipment, capacitors are widely used in various circuits to achieve functions such as energy storage, voltage stabilization and filtering. Traditional capacitors usually include an outer shell to encapsulate the internal dielectric and plates. However, most of the capacitor shells in the prior art adopt a single-layer structure design. Although this design can meet basic packaging requirements, its buffering capacity is relatively limited when facing external shocks or vibrations, which can easily cause damage to the internal components of the capacitor, thereby affecting the overall performance and life of the capacitor. Utility Model Content
[0003] In view of the deficiencies in the background technology, the utility model provides a common compensation capacitor with an elastic inner shell.
[0004] The technical solution adopted by the utility model is: a common compensation capacitor with an elastic inner shell, comprising an outer shell, an upper cover covering the upper end of the outer shell and a lower cover covering the bottom of the outer shell, and also comprising an elastic inner shell, the elastic inner shell comprising a plug connector respectively plugged with the upper cover and the lower cover, an inner protective shell connected to the plug connector, and an outer protective shell connected to the plug connector, a buffer gap is left between the inner protective shell and the outer protective shell and between the outer shell and the outer protective shell, and an elastic member that plays a buffering role is provided in the buffer gap.
[0005] Furthermore, the elastic member is a coil spring.
[0006] Furthermore, two ends of the elastic member located between the inner protective shell and the outer protective shell are respectively fixedly connected to the inner protective shell and the outer protective shell, and one end of the elastic member located between the outer shell and the outer protective shell is fixedly connected to the outer protective shell.
[0007] Furthermore, the plug connector is provided with a connector with a frustum structure, and the upper cover and the lower cover are provided with connecting holes for plugging and matching with the connector.

[0009] Furthermore, a grounding column is also provided on the upper cover.
[0010] The beneficial effect of the utility model is that the present application adds an elastic inner shell inside the capacitor, and the inner shell can effectively absorb and disperse the impact force and vibration energy applied from the outside. By setting a buffer gap between the inner protective shell and the outer protective shell, and between the outer shell and the outer protective shell, and filling the gap with elastic parts, the direct impact on the internal components of the capacitor can be significantly reduced, thereby avoiding physical damage to the internal plates and dielectrics, enhancing the mechanical stability of the capacitor, and extending the service life of the capacitor.
