Description

Technical Field

[0001] The present application belongs to the technical field of filter equipment production, and specifically relates to a shielding grounding reliability connection structure of a filter connector. Background Art

[0002] In the prior art, plate-type filter capacitors are electronic components primarily used for filtering in circuits to eliminate noise and interference, improving circuit stability and performance. They are commonly used in power management systems, such as input and output filtering in switching power supplies, and filtering high-frequency noise in high-frequency digital circuits. Plate-type filter capacitors can be made of different materials and specifications to suit specific frequency response and electrical characteristics, depending on the application requirements.

[0003] In the prior art, plate-type filters are often used in conjunction with a housing. The housing can provide physical protection for the plate-type filter to prevent damage to electronic components caused by external environmental factors such as humidity, dust, and mechanical impact. The housing can also dissipate heat to help electronic components maintain a suitable operating temperature, thereby ensuring long-term stable operation. The shielding grounding structure of existing filter connectors usually adopts welding, crimping, etc. Although the connection can be achieved, the welding process may cause thermal damage, and the outer layer of the filter is usually chrome-plated, which may easily lead to loose welding. The shielding material usually used for crimping is usually a non-elastic material. The crimping process is affected by factors such as the dimensional tolerance of the shielding material, and there is a problem of loose contact. When the voltage fluctuates, the filter capacitor cannot be connected to the housing for grounding, and the filter equipment is prone to short circuit and burnout, which significantly reduces the reliability and service life of the equipment. Improvements are urgently needed. Utility Model Content

[0022] The present application provides a shielding grounding reliability connection structure of a filter connector, which includes a filter body, a grounding shielding component arranged on the filter body, and a connecting component arranged between the filter body and the grounding shielding component. By setting the material of the grounding shielding component to an elastic metal material and arranging a connecting component between the filter body and the grounding shielding component, the grounding shielding component can be fitted with the outer wall of the filter body, effectively avoiding the situation where the grounding shielding component is not welded firmly, and can also avoid the grounding shielding component being affected by factors such as the dimensional tolerance of the shielding material during the crimping process. When the voltage of the filter body fluctuates greatly, the grounding shielding component is easy to fall off the grounding shielding component body, thereby causing the filter equipment to be overloaded and burned.

[0036] The present application provides a shielding grounding reliability connection structure of a filter connector, which includes a filter body, a grounding shielding component arranged on the filter body, and a connecting component arranged between the filter body and the grounding shielding component. By setting the material of the grounding shielding component to an elastic metal material and arranging a connecting component between the filter body and the grounding shielding component, the grounding shielding component can be fitted with the outer wall of the filter body, effectively avoiding the situation where the grounding shielding component is not welded firmly, and can also avoid the grounding shielding component being affected by factors such as the dimensional tolerance of the shielding material during the crimping process.
