The housing of this capacitor is the tubular structure of upper end open, end cap is for closing the opening of housing, flange four, flange five, flange six, flange seven and flange eight is formed by carrying out turnover on end cap, thus the flange one of housing, flange two and flange three are wrapped up, thus formed fixing by the closure of openings of housing, and multiple flange and the design that mutually reclines, thus extend the path of sealing, add sealing property, extend service life.
In above-mentioned capacitor, the upper surface of described flange three offers annular groove, and described flange eight has annular lug, and described annular lug embeds in described annular groove.By annular lug and the mating reaction of annular groove, extend the path of sealing further, improve the sealing property of capacitor, extend service life.
In above-mentioned capacitor, described flange five having annular mounting groove, be embedded with O-ring seal in described annular mounting groove, described O-ring seal is set in outside flange two and is resisted against the surface of flange two and forms sealing.By arranging O-ring seal, define double sealing effect, further increase the sealing property of capacitor, extend service life.
In above-mentioned capacitor, described end cap offering through hole, described capacitor core is filled with sealing resin in described through hole and the gap described capacitor core and described through hole hole wall.In order to easy to assembly, the through-hole aperture on usual end cap is bigger than the radial dimension of capacitor core, by filling sealing resin between capacitor core and through hole hole wall, improves stability and the fastness of capacitor core, improves the sealing of end cap simultaneously.
In above-mentioned capacitor, also having the annular shoulder block of protrusion in described end cap, be filled with sealing block in described end cap, described sealing block upper end abuts in end cap top, lower end is resisted against on annular shoulder block, and described capacitor core sequentially passes through sealing block and through hole stretches out outside end cap.By design annular shoulder block, and it is provided with sealing block between annular shoulder block and the top of end cap, thus forms triple seal, further increase the sealing property of capacitor, extend service life.
In above-mentioned capacitor, described end cap uses plastics or elastomeric material to make.End cap uses plastics or elastomeric material to make, and insulate non-conductive, and itself has certain elasticity, and switch is convenient, and has certain pretightning force, and sealing effectiveness is more preferably.
Compared with prior art, this capacitor has the advantage that 1, by carrying out turnover formation flange four, flange five, flange six, flange seven and flange eight on end cap, thus the flange one of housing, flange two and flange three are wrapped up, multiple flange and the design mutually reclined, thus extend the path of sealing, add sealing property, extend service life.The design of 2, O-ring seal, sealing resin and sealing block, thus formed multi-sealed between end cap and housing, further increase sealing property, extend service life.
