Capacitor and preparation method and installation method thereof

Abstract

The invention discloses a capacitor and a preparation method and an installation method of the capacitor, the capacitor comprises a capacitor body, a first pin and a second pin extend out of the right side end face of the capacitor body, the first pin and the second pin respectively comprise a protection pin, a heat dissipation pin and a welding pin which are the same, the length of the heat dissipation pin is larger than the radius of the capacitor body, and the length of the welding pin is larger than the radius of the capacitor body. The surface of the upper end of each welding pin is provided with a plurality of uniformly distributed through holes, each through hole is in a quadrangular frustum pyramid shape, the four side faces of each quadrangular frustum pyramid obliquely extend upwards by 30 degrees to form a circular hole channel, and the through holes and the circular hole channels are filled with soldering tin. The whole capacitor is good in heat dissipation effect, space-saving, tighter in welding, material-saving, and capable of reducing occupational diseases of workers. Potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the technical field of capacitor application, in particular to a capacitor and a preparation method and installation method of the capacitor. Background technique [0002] Two conductors that are close to each other, with a non-conductive insulating medium sandwiched between them, constitute a capacitor. When a voltage is applied between the two plates of the capacitor, the capacitor will store charge, and the capacitance of the capacitor is numerical. It is equal to the ratio of the amount of charge on a conductive plate to the voltage between the two plates. The basic unit of capacitance of a capacitor is Farad (F). In the circuit diagram, the letter C is usually used to represent the capacitive element. In a DC circuit, Capacitors are equivalent to open circuits. Capacitors are components that can store charges and are also one of the most commonly used electronic components. The types of capacitors can be divided into non-p...

AI Technical Summary

Problems solved by technology

[0003] The space height of the traditional vertical capacitor is too high, which is too wasteful of space, while the seated capacitor is too closely connected to the circuit board, the high temperature generated by the capacitor in the working process is easy to damage the circuit board body, and the welding process of the existing capacitor is complicated. The tightness is not enough, the solder raw materials are seriously wasted in the soldering process, and the soldering tin on the circuit board is irregular, causing unnecessary safety hazards and causing large manual operation errors. A capacitor and its preparation method and installation method are urgently needed to solve the above problems. question
