a timing capacitor

Abstract

The present invention discloses a timing capacitor. The timing capacitor comprises a shell, a capacitor component group and a timer. The inside of the shell forms a cavity, the top of the shell formsan opening, the shell is provided with a sealing plate used for closing and opening the opening, and the bottom of the shell is provided with a metal panel. The capacitor component group comprises a hard insulating inner liner, an electrolyte, a dielectric baffle, an electrode bar, connecting terminal(s), an insulating filling material and a discharge resistor. The top of the hard insulating innerliner has no cover seal, the top of the hard insulating inner liner is provided with a coating layer, and the insulating filling material and an adsorbent cover the coating layer. The hard insulatinginner liner is located in the shell, the hard insulating inner liner is tightly connected with the inner wall of the shell, the top of the hard insulating inner liner is provided with the insulatingfilling material, and the electrolyte is located in the hard insulating inner liner. The timer is arranged in the upside of the inner cavity of the shell, the timer is fixed on the lower surface of the sealing plate, and the timer is connected with the connecting terminal(s) via wires. The present invention provides a timing capacitor capable of blocking a capacitor circuit.

Description

technical field [0001] The invention belongs to the field of electronic capacitors, in particular to a timing capacitor. Background technique [0002] From the localization of color TVs in the 1980s to the popularization of home appliances today, my country's capacitor industry has achieved unprecedented development, fully meeting the needs of the development of various electronic complete machines in terms of quantity, quality, and service. There are also various types of capacitors, such as: aluminum electrolytic capacitors, film capacitors, ceramic capacitors, monolithic capacitors, paper capacitors, trimmer capacitors, ceramic capacitors, mica capacitors and glass glaze capacitors, etc. The types are complex and diverse. , the capacitor field has also reached saturation.

The insulation effect between the two-pole circuit components in the capacitor is poor, and it is easy to break down and short-circui...

AI Technical Summary

Problems solved by technology

[0003] The existing capacitors mainly have the following defects: 1. The insulation effect between the two-pole circuit components in the capacitor is poor, and it is easy to break down and short-circuit, causing high-temperature bursts and even burning; 2. Even when the power is cut off, the voltage stored in the capacitor element If it still exists and the insulation effect of the capacitor shell is poor, if the user touches the capacitor, it is easy to cause the danger of electric shock to the human body; The capacitor is short-circuited, causing a high-temperature explosion or even burning
