Description
Technical field
The utility model relates to technical field of electric appliances, particularly relates to a kind of electric capacity.
Background technology
Capacitor, being usually called for short its ability holding electric charge is electric capacity, represents by letter C.Definition 1: capacitor, as the term suggests being ' container of dress electricity ', is a kind of device holding electric charge.English name: capacitor.Capacitor is one of a large amount of electronic component used in electronic equipment, be widely used in circuit every straight-through friendship, coupling, bypass, filtering, resonant tank, power conversion, the aspects such as control.Definition 2: capacitor, any two insulated from each other and all form a capacitor between the conductor (comprising wire) of being separated by very near.Electric capacity is different from capacitor.Electric capacity is fundamental physical quantity, symbol C, and unit is F (farad).
Electric capacity is one of a large amount of electronic component used in electronic equipment, be widely used in the circuit such as power filter, signal filtering, signal coupling, resonance, filtering, compensation, discharge and recharge, energy storage, stopping direct current, in existing capacitor, between the circuit block of the two poles of the earth, insulation effect is poor, easy puncture short, cause explosive spalling, even burn, when capacitor case material is aluminium material simultaneously, easily distortion is produced during shock, destroy capacitor element, also easily cause capacitor short-circuit, cause explosive spalling, even burn.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of electric capacity.
The utility model is achieved through the following technical solutions:
A kind of electric capacity, comprise capacitance shell, described capacitance shell side is provided with seal cover, one end of described capacitance shell is provided with positive pole pin and negative pole pin, described positive pole pin, negative pole pin are connected with the first capacitance core, the second capacitance core respectively by wire, be positioned at capacitance shell inside and be provided with insulation fill stratum near described first capacitance core, the second capacitance core, outside described first capacitance core, the second capacitance core and upside is provided with explosion-proof layer, and the wire of described positive pole pin, negative pole pin is provided with fuse.
As optimal technical scheme of the present utility model, described insulation fill stratum is filled in capacitance shell inside.
As optimal technical scheme of the present utility model, described explosion-proof layer is fixedly connected with between insulation fill stratum.
As optimal technical scheme of the present utility model, described fuse two ends are connected with wire.
Compared with prior art; the beneficial effects of the utility model are: the utility model structure is simple, and reasonable in design, the utility model first capacitance core, the second capacitance core are in insulation fill stratum; insulation fill stratum can the parts of capacitor for voltage protection inside not be destroyed, and prevents short circuit or electric leakage.Insulation fill stratum place in the enclosure and be filled between the first capacitance core, the second capacitance core, insulation effect is good, simultaneously fuse can fuse when high temperature appears in capacitor internal, avoids the danger that electric shock occurs, and electric capacity can be avoided under the effect of explosion-proof layer to blast phenomenon.
