a capacitor

Abstract

The invention discloses a capacitor, which comprises a housing, a shell cover, terminals and aluminum shells with cores, wherein the housing is of a structure of which the bottom is sealed, the top is open and the inside is hollow; the aluminum shells are arranged in an internal hollow cavity of the housing; the terminals are fixed on the shell cover; each terminal comprises an injection molding part, a conductive copper bar, a sleeve part, a wire pressing part and a spring sheet; the lower end of each conductive copper bar passes through the corresponding injection molding part and is connected with one extraction electrode at the upper end of the corresponding aluminum shell until the core in the corresponding aluminum shell; the upper end of each conductive copper bar is exposed outside for a certain height to provide one end connected with one external circuit; the aluminum shells are arranged in the internal hollow cavity of the housing through an installation bracket; the housing also comprises movable support assemblies; the bottom of the housing is of a rectangular sag structure; and the movable support assemblies and a base body are in sliding fit. The capacitor has the advantages that an external wire connector is safe, stable, simple in structure and easy to connect, an interface is convenient to dismantle and clean, the cores are convenient to assemble, good in stability after being assembled and convenient to dismantle and replace, and support blocks are free to retract and extend.

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to a capacitor. Background technique [0002] Capacitors, usually referred to as capacitance for their ability to hold charges, are denoted by the letter C. Definition 1: Capacitor, as the name suggests, is a "container for charging", a device that holds charges. English name: capacitor. Capacitors are one of the electronic components widely used in electronic equipment, and are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control, etc. in circuits. Definition 2: Capacitor, any two conductors (including wires) that are insulated from each other and are very close to each other form a capacitor. [0003] At present, the external wires are often arranged in the ports of the capacitor terminals by snap-fitting or fastening with fasteners. When the terminals of the aluminum profiles are heated or subjected to external forces,...

Problems solved by technology

Because the support block protrudes from the base, the capacitor takes up a lot of space when stored, and it is inconvenient to pack when it is transported
