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
The present invention relates to capacitor technology field, specifically belong to a kind of Multifunctional AC capacitor.
Background technology
Capacitor, is referred to as electric capacity usually, is a kind of electric elements that in electronic equipment, use amount is maximum, be widely used in circuit every straight-through friendship, coupling, bypass, filtering, resonant tank, power conversion control aspect.
In the prior art, capacitor is by cap, housing and core body composition, all can leading-out terminal pin on general cap, and for being connected in circuit, but the pin of capacitor is all generally directly be welded on core body.AC capacitor realizes the restriction of principle due to it, under there is the situations such as flaw in, material aging, material too high in overvoltage, overcurrent, ambient temperature, due to wiring overload, aging etc. can there is heating burning situation, overtemperature can with slowly guiding to capacitor internal, cause the accidents such as capacitor is on fire, blast, cause household appliances on fire, bring life and property loss to user.And in permanent use, after aging fracture appears in pin, generally all can change whole capacitor, but capacitor itself does not break down, therefore, produce unnecessary waste.
Summary of the invention
The object of this invention is to provide a kind of Multifunctional AC capacitor, overcome the deficiencies in the prior art, project organization is reasonable, by arranging heavy bar and outer solder joint, when there is heating burning situation in external connection, outer solder joint melts, and internal wiring falls with heavy bar, open circuit, capacitor for voltage protection core, when capacitor is inverted, external connection heating burning, heat causes interior solder joint to melt, spring is thrown off constraint and is flicked internal wiring, capacitor for voltage protection core, thus comprehensively capacitor is shielded, prevent the danger of capacitor blast on fire from occurring; Due to pin be connected by screw with internal wiring, pin and housing by fastener clamping, be convenient for changing pin and internal wiring, make the service time that capacitor reaches more of a specified duration.
The technical solution used in the present invention is as follows:
A kind of Multifunctional AC capacitor, comprise housing, capacitor core, described capacitor core is positioned at housing, housing is provided with pin, protective cover is provided with outside pin, protective cover bottom connects housing, heavy bar is provided with in described protective cover cavity, heavy bar is wound around internal wiring, described pin connects internal wiring lower end, housing 1 is stretched out in internal wiring upper end, internal wiring upper end is welded to connect by outer solder joint and external connection, outer solder joint is arranged on protective cover upper surface, protective cover lower surface is provided with interior solder joint, interior solder joint side contacts with internal wiring, interior solder joint opposite side is provided with side plate, side plate connects protective cover lower surface, spring is provided with between described side plate and interior solder joint.
The material of described interior solder joint and described outer solder joint is tin.The fusing point of tin is low, can melt very soon.
Described pin is connected by screw with internal wiring lower end.Screw replacing internal wiring easy to connect.
Described pin and housing are by fastener clamping.Be convenient for changing pin.
Described protective cover is connected by screw with housing.Screw is easy to connect opens protective cover, is convenient to maintenance.
Compared with the prior art, beneficial effect of the present invention is as follows:
The present invention is by arranging heavy bar and outer solder joint, and when heating burning situation appears in external connection, outer solder joint melts, internal wiring falls with heavy bar, open circuit, capacitor for voltage protection core, when capacitor is inverted, external connection heating burning, heat causes interior solder joint to melt, and spring is thrown off constraint and flicked internal wiring, capacitor for voltage protection core, thus comprehensively capacitor is shielded, prevent the danger of capacitor blast on fire from occurring; Due to pin be connected by screw with internal wiring, pin and housing by fastener clamping, be convenient for changing pin and internal wiring, make the service time that capacitor reaches more of a specified duration.
