Description
Technical field
The present invention relates to capacitor technology field, in particular to a kind of convenient electrical condenser installed.
Background technology
Electrical condenser usually letter be called electric capacity, be a kind of device holding electric charge. Electric capacity is one of a large amount of electronic component used in electronics, be widely used in circuit every straight-through friendship, coupling, bypass, filtering, tuning loop, energy transformation, the aspects such as control. For effectively transmitting or change electric energy, it is to increase its power factor, to be used electrical condenser usually. In the prior art, electrical condenser is made up of shell and capacitor core, and wherein, fuse is placed in shell, and the heat that capacitor core produces in working process is dispelled the heat by connection terminal and shell. And due to radiating effect good not, electrical condenser is easy to occur thermal ageing phenomenon in long-time high temperature situation, thus seriously affects electrical condenser work-ing life, and therefore the heat dissipation problem of electrical condenser also more and more causes the attention of people.
Summary of the invention
The main purpose of the present invention is to provide a kind of good heat dissipation effect and the convenient electrical condenser installed.
The present invention proposes a kind of convenient electrical condenser installed, the capacitor element comprising shell and be placed in described shell, described capacitor element comprises core, the capacitor element being centered around in described core, it is arranged on anode electrode plate and the negative el at capacitor element two ends, and the negative wire of the positive wire of extraction from described anode electrode plate and extraction from described negative el, described shell is by the ceramic package being added with the CaO-R2O-ZrO2 base LTCC stupalith that massfraction is 7.5%Al2O3 and at high temperature sintering, one end of described shell is that opening is arranged, described capacitor element loads in described shell from the opening end of described shell, it is filled with epoxy resin between described shell inner chamber and described capacitor element, open end cap at described shell establishes rubber seal plug, positive wire hole and negative wire hole is had beyond the Great Wall in described rubber seal, described positive wire stretches out from described positive wire hole, described negative wire stretches out from described negative wire hole, plug it is equipped with beyond the Great Wall in described rubber seal, described plug and described positive wire, described negative wire is electrically connected.
Preferably, also comprising a discharging resistance, described discharging resistance is electrically connected with described anode electrode plate, described negative el.
Preferably, described epoxy resin is heat-conduction epoxy resin.
The useful effect of the electrical condenser of the convenient installation of the present invention is:
The shell of the present invention is by the ceramic package being added with the CaO-R2O-ZrO2 base LTCC stupalith that massfraction is 7.5%Al2O3 and at high temperature sintering, the Al2O3 wherein added plays structure and modifies ceramic structure effect, along with Al2O3 content increases, the relative permittivity of ceramic package is progressive law, reduce the dielectric loss of electrical condenser, and improve bending strength so that it is profile is firm, is not easily out of shape. It is filled with epoxy resin in the enclosure between chamber and capacitor element, shell can be propped up, and insulation effect is good, moreover it is possible to protection capacitor element, prevents short circuit or electric leakage.
Epoxy resin is heat-conduction epoxy resin, can be conducted rapidly by the heat of capacitor internal, to reach the effect of quick heat radiating.
At the plug that rubber seal is equipped with positive wire, negative wire are electrically connected, when electrical condenser is installed, directly insert in corresponding jack by plug, it is achieved the installation of electrical condenser and electrical connection beyond the Great Wall, easy for installation.
