The capacitor comprises a shell, wherein the shell is covered with the end cover; a capacitor core is arranged in the shell; the shell is cured integrally with the end cover through epoxy resin; a connection terminal is arranged in the end cover; the bottom end of the connection terminal is provided with the lead of which the tail end is electrically connected with the capacitor core; the neck part of the shell is molded into a corrugated pipe section; and the outer shell wall of the shell is provided with a latticed metal net.

Description

The incorporate explosion-proof electric capacity of lead end cap that a kind of reactive circuit disturbs

Technical field

The utility model relates to electron electric power device field, is specially the incorporate explosion-proof electric capacity of lead end cap that a kind of reactive circuit disturbs.

Background technology

Electric capacity is one of a large amount of electronic components that use in the electronic equipment, is widely used in every aspects such as straight, coupling, bypass, filtering, resonant tank, power conversion, control circuits.Electric capacity is to be made of any two insulated from each other and very near conductors of being separated by, and electric capacity is equivalent to open circuit in DC circuit, and in alternating current circuit, circuit passes through between electric capacity by the form of field.Its binding post of the electric capacity of prior art is positioned at the end cap top, be connected with the lead that the electric capacity core body is drawn by screw or other buss in end cap inside, such structure is comparatively complicated, resistance is bigger, and connecting portion is loosening can to cause the electric capacity cisco unity malfunction, and be difficult for finding reason, repair inconvenience.Because electric capacity is widely used in the circuit, and the electric field energy in the circuit tends to capacitive property is exerted an influence, serious also can cause electric capacity breakdown simultaneously.And the circuit circumstance complication of electric capacity work, the phenomenon of electric capacity blast also can appear in the electric capacity overload sometimes, if there is not blast resistance construction in the electric capacity, then can cause the injury to the user

The utility model content

The purpose of this utility model provides the incorporate electric capacity of a kind of lead end cap, to solve capacitance structure complexity of the prior art, repairs inconvenience during the electric capacity cisco unity malfunction, is subject to the influence of external circuitry electric field energy, the problem that the electric capacity overload can be blasted.

In order to achieve the above object, the technical solution adopted in the utility model is:

The incorporate explosion-proof electric capacity of lead end cap that a kind of reactive circuit disturbs, include uncovered housing, described housing open-mouth is covered with end cap, the electric capacity core body is arranged in the described housing, it is characterized in that: described end cap is the plastic cement end cap, described housing and end cap are one by epoxy resin cure, also include binding post, described binding post is installed in the end cap and is cured as one with end cap, described binding post bottom is connected with the lead with the binding post one, and described wire end stretches in the housing and is electrically connected with the electric capacity core body; Housing neck near the end cap place of covering is shaped to bellows piece, and described end cap bottom is stretched in the bellows piece of housing neck; Also be printed with latticed wire netting on the described housing shell wall.

The utility model is simple in structure, convenient maintenance, end cap and housing are the explosion-proof that one can strengthen electric capacity by epoxy resin cure, by binding post, lead is integrated, and binding post and end cap be cured as one, wire end directly is electrically connected with the electric capacity core body, and so not only resistance is less, and tie point is less.By the housing neck is shaped to bellows piece, the end cap bottom is stretched in the housing neck bellows piece, applies a stress to end cap like this, when electric capacity transships, can not pop easily.Print latticed wire netting on the housing shell wall of electric capacity, latticed wire netting plays the effect of shielding, and electric capacity is not vulnerable to the interference of other electronic equipment electric field energies in the circuit when being connected the circuit use like this.The utility model is easy to maintenance, has improved the useful life of electric capacity, has reduced the possibility that potential safety hazard occurs.
