Easy-to-adjust multi-capacitance-value capacitor

Abstract

The invention discloses an easy-to-adjust multi-capacitance-value capacitor. A plurality of capacitor units are installed at capacitor installation sites in a housing respectively, and first pins of the capacitor units are located on the side walls, away from the housing, of second pins; a first main pin penetrates through a first installation opening of a cover plate, and a second main pin penetrates through a second installation opening of the cover plate; a plurality of through grooves in the cover plate are formed around the first installation opening, a weld line is arranged at the bottomof the cover plate and crosses over the through grooves in sequence, and the weld line is connected with the second main pin; the first pins of the capacitor units are connected with the lower end ofthe first main pin, and the second pins are connected with the weld line; an isolation film is arranged in each through groove. In the optimally designed easy-to-adjust multi-capacitance-value capacitor, by selecting the number of capacitor units in parallel connection according to needs, selective adjustment of multiple capacitance values is realized; besides, by means of the optimal design of the pin connection mode, on one hand, the positive and negative pole pins can be conveniently distinguished, and on the other hand, the pins can be conveniently connected when the capacitor units are installed, so that the subsequent processing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a multi-capacitance capacitor whose pins are easy to distinguish. Background technique [0002] Capacitors are extremely widely used electronic components. With the development of technology, capacitors whose capacitance value can be changed according to the needs of use have appeared. However, the internal structure of this type of capacitor and the structure of its insulating terminal cover are relatively complex, resulting in high cost, easy disconnection or false welding of each connection, and large creepage distance of the power supply. Simultaneously, its internal components fail to make full use of the space in its housing, resulting in an insufficiently compact structure and a large footprint. In other words, the overall performance of this type of capacitor is poor. Contents of the invention [0003] In order to solve the technical problems in the background tec...
