Capacitor cover plate line bank
Technical field
The present invention relates to capacitor technology field, more particularly to a kind of capacitor cover plate line bank.
Background technology
The recombiner condenser explosion-protection equipment of domestic production at present, is all that capacitor manufacturer welds common cover terminal rod
Fuze, mixes plastics bursting diaphragm, then weld the blast resistance construction that iron electrode weld tabs constitutes capacitor.This blast resistance construction is for little Rong
Explosion-proof effect is still, but poor for the explosion-proof effect of the recombiner condenser of Large Copacity this technique for the recombiner condenser of amount,
Because large value capacitor capacity is big, it is easy to large value capacitor explosion-proof in advance, causes the service life of capacitor shorter,
Capacitor service efficiency is low, and cost increases.
The content of the invention
In order to solve technical problem present in background technology, the present invention proposes a kind of simple structure, explosion-proof efficiency high
Capacitor cover plate line bank.
A kind of capacitor cover plate line bank proposed by the present invention, including cover plate, upper insulating base, lower insulating base, upper insulating base
Cover plate front is arranged on, lower insulating base is arranged on the cover plate back side, and cover plate central position is provided with through hole, and upper insulating base upper end is provided with and connects
Line terminals, upper insulating base lower end is provided with the card column of insertion through hole;Lower insulating base upper end is provided with the groove corresponding with card column, lower exhausted
The circle that is dielectrically separated from being connected with card column is provided with the groove of edge seat, lower insulating base lower end is provided with conducting strip;Upper insulating base, it is lower absolutely
Edge seat is internal to be provided with interconnected explosion-proof plug perforation, and explosion-proof plug, explosion-proof plug one end and upper insulating base are provided with explosion-proof plug perforation
The binding post of upper end is connected, the other end is mutually welded with the conducting strip of lower insulating base lower end.
Preferably, the insulating board pasted on the cover board, the outward flange of insulating board are provided between cover plate and lower insulating base
Size is corresponding with the outward flange size of lower insulating base upper end.
Preferably, binding post is integrally formed with explosion-proof plug.
Preferably, it is dielectrically separated from the depth of the height higher than lower insulating base upper recess of circle.
Capacitor cover plate line bank of the invention, by capacitor from explosion deck design into test line bank construction, in the upper of cover plate
Lower surface is provided with a pair upper and lower insulating bases being mutually interlocked, convenient to install explosion-proof plug;The present invention improves the reliability of capacitor
Property, capacitor cost is reduced, greatly improve capacitor service efficiency, while explosion-proof effect may directly be seen by visual observation
Arrive, very convenient practicality.
Brief description of the drawings
Fig. 1 is the structural representation of capacitor cover plate line bank proposed by the present invention.
Specific embodiment
As shown in figure 1, Fig. 1 is the structural representation of capacitor cover plate line bank proposed by the present invention.
Reference picture 1, a kind of capacitor cover plate line bank proposed by the present invention, including cover plate 1, upper insulating base 2, lower insulating base
3, upper insulating base 2 is arranged on the front of cover plate 1, and lower insulating base 3 is arranged on the back side of cover plate 1, and the center of cover plate 1 is provided with through hole, on
The upper end of insulating base 2 is provided with binding post 4, and the lower end of upper insulating base 2 is provided with the card column 5 of insertion through hole;The lower upper end of insulating base 3 be provided with
The corresponding groove of card column 5, be provided with the groove of lower insulating base 3 be connected with card column 5 be dielectrically separated from circle 7, be dielectrically separated from circle 7
Highly higher than the depth of groove, the lower lower end of insulating base 3 is provided with conducting strip 6;It is provided with inside upper insulating base 2, lower insulating base 3 mutually
The explosion-proof plug perforation of connection, explosion-proof plug 8 is provided with explosion-proof plug perforation, the binding post of the one end of explosion-proof plug 8 and the upper end of upper insulating base 2
4 are connected, the other end is mutually welded with the conducting strip 6 of the lower lower end of insulating base 3.It is provided between cover plate 1 and lower insulating base 3 and is pasted onto cover plate
Insulating board 9 on 1, the outward flange size of insulating board 9 is corresponding with the outward flange size of the lower upper end of insulating base 3.
Wherein, binding post 4 is integrally formed with explosion-proof plug 8, simplifies production technology, reduces the set-up time, improves
Production efficiency.The present invention by capacitor from explosion deck design into test line bank construction, the front of cover plate 1, the back side be provided with a pair it is mutual
Upper insulating base 2, the lower insulating base 3 being interlocked, facilitate the installation of explosion-proof plug 11.
The present invention improves the reliability of capacitor, reduces capacitor cost, greatly improves capacitor service efficiency,
While explosion-proof effect may directly be seen by visual observation, very convenient practicality.
More than, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, technology according to the present invention scheme and its invention
Design is subject to equivalent or change, should all be included within the scope of the present invention.
