Description

Technical Field

[0001] The present invention relates to the technical field of electrical components, and in particular to an external assembly pin for an electrolytic capacitor. Background Art

[0002] An electrolytic capacitor is a type of capacitor with a metal foil (aluminum or tantalum) as the positive electrode. The oxide film (aluminum oxide or tantalum pentoxide) in close contact with the metal serves as the dielectric. The cathode is composed of a conductive material, an electrolyte (which can be liquid or solid), and other materials. The electrolyte is the primary component of the cathode, hence the name electrolytic capacitor. Furthermore, the positive and negative terminals of electrolytic capacitors must be connected correctly. Aluminum electrolytic capacitors can be divided into four categories: leaded aluminum electrolytic capacitors; horn-type aluminum electrolytic capacitors; bolt-on aluminum electrolytic capacitors; and solid-state aluminum electrolytic capacitors.

[0003] The pins of existing electrolytic capacitors mostly use a fixed connection structure using spot welding. If a pin fails during use, the entire capacitor needs to be replaced to ensure normal operation of the circuit, which increases working costs and reduces the overall service life. Therefore, an external assembly pin for electrolytic capacitors is designed.

[0004] After searching, Chinese patent number CN202310140707.1 discloses a pin-replaceable dual-clamp assembly fixed inductor, comprising an assembly bottom shell, an assembly top shell movably mounted on the upper end of the assembly bottom shell, an adapter snap-in slot pre-set on the outer side of the assembly bottom shell, a positioning through-hole pre-set in the middle position of the lower end of the side of the assembly bottom shell, an alignment snap-in slot pre-set on the upper end of the side of the assembly bottom shell, an assembly column fixedly mounted in the middle position of the interior of the assembly bottom shell, a matching slot pre-set inside the matching slot, an assembled winding movably mounted on the outside of the assembly column, a matching block fixedly mounted on the bottom of the matching snap-in block, and an external pin movably mounted inside the matching slot. The present invention optimizes and improves the packaging structure of existing fixed inductors, replacing the original resin or plastic packaging structure with a detachable structure with multiple snap-ins, enabling quick disassembly and assembly, making it more convenient to use and reducing work and maintenance costs.

[0005] The pins of the electrical components will oxidize, and the above patent cannot process the pins of the electrical components. In addition, the connection between the assembled pins and the capacitor body is not compact enough, and the capacitor is easily separated from the assembled pins. Summary of the Invention
