Description

Technical Field

[0001] The present invention relates to a preparation method of a tantalum capacitor, in particular to a chip-type conductive polymer tantalum capacitor, belonging to the technical field of tantalum capacitors. Background Art

[0002] For example, a tantalum capacitor disclosed in application number CN111210994A comprises: a tantalum body comprising tantalum powder; a tantalum wire exposed at one end surface of the tantalum body; an anode lead frame comprising a first electrode member and a second electrode member bent perpendicularly to the first electrode member; a cathode lead frame comprising a third electrode member and a fourth electrode member bent perpendicularly to the third electrode member, the third electrode member being spaced apart from the first electrode member, and the tantalum body being mounted on the upper surface of the third electrode member; an encapsulation portion covering the tantalum body and the tantalum wire, exposing the lower surfaces of the first and third electrode members and the outer surfaces of the second and fourth electrode members; the anode lead frame comprising a bent portion extending obliquely from a connection portion between the first and second electrode members, and an end of the bent portion being in contact with the tantalum wire.

[0003] Based on the search and analysis, the existing technology still has shortcomings:

[0004] The prior art uses a frame limiting structure. During use, the frame and the tantalum capacitor contact each other, resulting in poor heat dissipation. During use, heat is generated, which causes the shell or fixing parts to age, causing the tantalum capacitor to become loosely fixed. The present application uses an extruded connector to cooperate with the tantalum capacitor and the connecting plate group to facilitate installation and operation, and prevent the problem of equipment becoming loose over time. In view of the shortcomings of the prior art, a chip-type conductive polymer tantalum capacitor is needed to improve the above-mentioned shortcomings. Summary of the Invention

[0005] The main purpose of the present invention is to provide a polymer tantalum capacitor with a chip-type conductive structure that is easy to disassemble and has a split, multi-directional heat dissipation function.

The two sides of the external plate 1 and the external plate 2 are respectively installed with an external guide plate, a positive electrode external interface, and a negative electrode external interface. A gap is provided between the tantalum capacitor body and the external plate 1 and the external plate 2. Connectors that connect to each other are installed on the inner sides of the external plate 1 and the external plate 2. A threaded fixing structure is installed in the connector. The external plate 1, the external plate 2, and the tantalum capacitor body are squeezed and connected by a guide plate. This achieves the function of multi-directional heat dissipation during use, facilitates installation and prevents loosening, and realizes the function of conducting on one side and energizing on the other side.
