Problems solved by technology

[0002] In the traditional microwave circuit of the prior art, the high-voltage capacitor and the high-voltage diode are separately installed and connected. In this way, the exposed high-voltage diode is more likely to be polluted by oily smoke and air impurities, so that the withstand voltage strength of the diode is low, which in turn leads to the breakdown of the diode. scrapped, thus affecting the normal operation of the entire system
In the past, some people wanted to integrate high-voltage capacitors and diodes, but they failed because of problems in connection and insulation.
Therefore, the service life of the diode is short, how to protect the diode and prolong the service life of the diode has become a difficult problem in the industry

Abstract

A high-voltage capacitor with a rectifying device comprises a casing (1) and two soldering terminals (3). A cover (2) is arranged at the opening end of the casing (1), a capacitor core (9) is arranged in the inner cavity of the casing (1), two electrodes of the capacitor core (9) are respectively soldered with one end of each soldering terminal (3) together, a resistor (7) is arranged between the two electrodes, the other ends of the soldering terminals (3) extend outside the cover (2), a silicon pad (5) is arranged between each soldering terminal (3) and the cover (2), and an insulating stool (4) is arranged around the end of each soldering terminal (3) extending outside the cover (2). The high-voltage capacitor also comprises a diode (8) which is arranged inside the inner cavity of the casing (1) and has one end thereof connected with the capacitor core (9) and the other end thereof connected with the cover (2), and insulating paper boards (6) are arranged between the diode (8) and the casing (1), between the diode (8) and the cover (2) and between the diode (8) and each soldering terminal (3). Compared with the prior art, the high-voltage capacitor is characterized by high withstand voltage strength of the diode, and long service life.

Description

Technical field: [0001] The invention belongs to the field of electronics, in particular to a high-voltage capacitor with a rectifying device. Background technique: [0002] In the traditional microwave circuit of the prior art, the high-voltage capacitor and the high-voltage diode are separately installed and connected. In this way, the exposed high-voltage diode is more likely to be polluted by oily smoke and air impurities, so that the withstand voltage strength of the diode is low, which in turn leads to the breakdown of the diode. scrapped, thereby affecting the normal operation of the entire system. Some people wanted to integrate high-voltage capacitors and diodes before, but they failed because of the inability to solve the problems of connection and insulation. Therefore, the service life of the diode is short, and how to protect the diode and prolong the service life of the diode has become a difficult problem in the industry.
