Directly-inserted capacitor

Abstract

The invention discloses a directly-inserted capacitor, which includes a sleeve body. A middle part of the sleeve body is provided with a matching cavity. The inside of the matching cavity is connectedwith a capacitor body. The capacitor body is composed of an aluminum shell, a capacitor core and a rubber seal. The capacitor core is embedded in the aluminum shell. The opening of one end of the aluminum shell is fixedly connected to the rubber seal. One end of the capacitor core is fixedly connected to a positive pin and a negative pin. One end of the positive pin and one end of the negative pin both pass through the rubber seal and are located outside the aluminum shell. The DIP capacitor has the beneficial effects of avoiding the wrapping manner of a traditional capacitor by using the sleeve body and the aluminum cover plate, preventing the capacitor body from being exposed and damaged by the cooperation of the sleeve body and the aluminum cover plate, and providing the aluminum coverplate and a heat conducting seat with good heat conduction performance, such that the heat on the surface of the capacitor body can be quickly dissipated out to achieve the effects of rapid heat dissipation and prolonging the service life of the capacitor.

Description

technical field [0001] The invention relates to a capacitor, in particular to an in-line capacitor. Background technique [0002] Capacitors, usually referred to as capacitance for their ability to hold charges, are denoted by the letter C. Definition 1: A capacitor, as the name implies, is a 'charged container', 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: Capacitors, any two are insulated from each other A capacitor is formed between conductors (including wires) that are very close to each other. [0003] In-line capacitors are one type of capacitors. However, the existing in-line capacitors still have some shortcomings. Most of the existing in-line capacitors are coated to wrap the shell. Abrasion leads to the exposure of the shell, which ...

Problems solved by technology

[0004] The purpose of the present invention is to provide an in-line capacitor to solve the problem that most of the existing in-line capacitors proposed in the above background technology adopt the form of coating to wrap the shell, and the shell is often exposed due to wear during use. This will lead to damage to the inner core. At the same time, the use of coating wrapping in the existing in-line capacitors will lead to poor heat dissipation and reduced service life.
