Capacitor cover plate line bank
Technical field
The present invention relates to capacitor technology field, relate in particular to a kind of capacitor cover plate line bank.
Background technology
The recombiner condenser explosion-protection equipment of domestic current production, is all that common cover terminal rod is welded fuze by capacitor manufacturer, mixes plastics bursting diaphragm, then welds the blast resistance construction of ferroelectric utmost point weld tabs composition capacitor.This blast resistance construction explosion-proof effect for the recombiner condenser of low capacity still can, but the explosion-proof effect for jumbo this technique of recombiner condenser is poor, because large value capacitor capacity is large, make large value capacitor as easy as rolling off a log explosion-proof in advance, cause the useful life of capacitor shorter, capacitor service efficiency is low, and cost increases.
Summary of the invention
In order to solve the technical problem existing in background technology, the present invention proposes one simple in structure, the capacitor cover plate line bank that explosion-proof efficiency is high.
A kind of capacitor cover plate line bank that the present invention proposes, comprise cover plate, upper insulating base, lower insulating base, upper insulating base is arranged on cover plate front, lower insulating base is arranged on the cover plate back side, cover plate center is provided with through hole, upper insulating base upper end is provided with binding post, and upper insulating base lower end is provided with the card column of inserting through hole; Lower insulating base upper end is provided with the groove corresponding with card column, is provided with the insulation cage ring being connected with card column in the groove of lower insulating base, and lower insulating base lower end is provided with conducting strip; Be provided with the explosion-proof plug perforation being interconnected in upper insulating base, lower insulating base inside, in explosion-proof plug perforation, be provided with explosion-proof plug, explosion-proof plug one end is connected with the binding post of upper insulating base upper end, the conducting strip of the other end and lower insulating base lower end welds mutually.
Preferably, between cover plate and lower insulating base, be provided with stickup insulating board on the cover board, the outward flange size of insulating board is corresponding with the outward flange size of lower insulating base upper end.
Preferably, binding post and explosion-proof plug are one-body molded.
Preferably, the height of insulation cage ring is higher than the degree of depth of lower insulating base upper end groove.
Capacitor cover plate line bank of the present invention, is designed to test line bank construction by capacitor from explosion cover plate, is provided with the upper and lower insulating base of a pair of mutual fastening in the upper and lower surface of cover plate, the convenient explosion-proof plug of installing; The present invention has improved the reliability of capacitor, has reduced capacitor cost, and capacitor service efficiency is improved greatly, and explosion-proof effect directly may be seen by visual simultaneously, very convenient practicality.

Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of the capacitor cover plate line bank that proposes of the present invention.
With reference to Fig. 1, a kind of capacitor cover plate line bank that the present invention proposes, comprise cover plate 1, upper insulating base 2, lower insulating base 3, upper insulating base 2 is arranged on cover plate 1 front, lower insulating base 3 is arranged on cover plate 1 back side, cover plate 1 center is provided with through hole, and upper insulating base 2 upper ends are provided with binding post 4, and upper insulating base 2 lower ends are provided with the card column 5 of inserting through hole; Lower insulating base 3 upper ends are provided with the groove corresponding with card column 5, are provided with the insulation cage ring 7 being connected with card column 5 in the groove of lower insulating base 3, and the height of insulation cage ring 7 is higher than the degree of depth of groove, and lower insulating base 3 lower ends are provided with conducting strip 6; Be provided with the explosion-proof plug perforation being interconnected in upper insulating base 2, lower insulating base 3 inside, in explosion-proof plug perforation, be provided with explosion-proof plug 8, explosion-proof plug 8 one end are connected with the binding post 4 of upper insulating base 2 upper ends, the conducting strip 6 of the other end and lower insulating base 3 lower ends welds mutually.Between cover plate 1 and lower insulating base 3, be provided with the insulating board 9 sticking on cover plate 1, the outward flange size of insulating board 9 is corresponding with the outward flange size of lower insulating base 3 upper ends.
Wherein, binding post 4 is one-body molded with explosion-proof plug 8, has simplified production technology, has reduced the set-up time, has improved production efficiency.Capacitor from explosion cover plate is designed to test line bank construction by the present invention, is provided with upper insulating base 2, the lower insulating base 3 of a pair of mutual fastening at front, the back side of cover plate 1, facilitates the installation of explosion-proof plug 11.
The present invention has improved the reliability of capacitor, has reduced capacitor cost, and capacitor service efficiency is improved greatly, and explosion-proof effect directly may be seen by visual simultaneously, very convenient practicality.
Above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
