Multifunctional alternating current capacitor

Abstract

The invention discloses a multifunctional alternating current capacitor. A capacitor core is positioned in a shell; the shell is provided with a pin; the external of the pin is provided with a protective cover; the lower part of the protective cover is connected with the shell; a weight lever is arranged in the protective cover cavity; the weight lever is wrapped with an internal connecting wire; the pin is connected with the lower end of the inner connecting wire; the upper end of the inner connecting wire is welded with an outer connecting wire through an outer welding point; an inner welding point is arranged on the lower end plane of the protective cover; one side of the inner welding point is in contact with the inner connecting wire; a side plate is arranged on the other side of the inner welding point; and a spring is arranged between the side plate and the inner welding point. The multifunctional alternating current capacitor is provided with the weight lever and the outer welding point; when the outer connecting wire is heating and over-burnt, the outer welding point is melted; the inner connecting wire falls off with the weight lever to disconnect a circuit; when the capacitor is inverted, the outer connecting wire is heating and over-burnt, the heat melts the inner welding point, the spring bounces off the inner connecting wire for protecting the capacitor; and the pin is connected with the inner connecting wire by screws, and the pin is clamped with the shell, so that the pin can the inner connecting wire are convenient to replace.

Description

Technical field [0001] The invention relates to the technical field of capacitors, in particular to a multifunctional AC capacitor. Background technique [0002] Capacitors, usually called capacitors, are the most widely used electrical components in electronic equipment. They are widely used in circuits for blocking, coupling, bypassing, filtering, tuning loops, and energy conversion control. [0003] In the prior art, the capacitor is composed of a shell cover, a shell and a core body. Terminal pins are usually drawn on the shell cover for connection to the circuit, but the capacitor pins are generally directly welded to the core body. Up. Due to the limitation of the realization principle of AC capacitors, in the case of overvoltage, overcurrent, high ambient temperature, material aging, material defects, etc., due to the overload and aging of the wiring, heating and burning will occur, and the overheating temperature will slow down. Slowly lead to the inside of the capacitor,...

AI Technical Summary

Problems solved by technology

Due to the limitations of its realization principle, AC capacitors will generate heat and overburn due to overload and aging of the wiring under the conditions of overvoltage, overcurrent, high ambient temperature, material aging, and material defects, etc., and the overheating temperature will slow down. Slow lead to the inside of the capacitor, causing the capacitor to catch fire, explode and other accidents, resulting in fire of home appliances, causing loss of life and property to users

Moreover, in long-term use, when the pins are aging and fractured, the entire capacitor is generally replaced, but the capacitor itself has not failed, so unnecessary waste is generated.
