Description
Technical field
The present invention relates to a kind of capacitor binding post, be related specifically to a kind of capacitor binding post being applicable to work in HI high impact voltage environment.
Background technology
Traditional capacitor binding post is resembled glue sealing ring and nut etc. formed by conductive copper bar, working of plastics, metal cap, silicon, when there is very high surge voltage, there are arcing electric discharge phenomena between conductive copper bar and metal cap, make metal-back cover strip electricity afterwards easily and the conductive copper bar of capacitor internal or metal nuts discharge thus cause capacitor to occur short circuit, the even serious accident such as blast.The anti-impacting with high pressure performance of the capacitor binding post of prior art haves much room for improvement.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, the capacitor binding post that a kind of anti-impacting with high pressure, security performance are good is provided.
Technical scheme of the present invention is as follows:
A kind of capacitor binding post, comprise the metal cap of capacitor, and be installed on two groups of terminals that metal-back covers, terminal comprises threaded conductive copper bar, moulding, silica gel sealing ring and metal nuts, after assembling, conducting rod is through moulding, metal cap, silica gel sealing ring and metal nuts, is provided with silica gel sealing ring, it is characterized in that: described silica gel sealing ring bottom is also provided with high-voltage insulation cap in the gap between conducting rod and metal cap; High-voltage insulation cap outside is insulation crust, and insulation crust entirety becomes hollow cylindrical, becomes spill with holes by the cross section entirety of its center line; High-voltage insulation cap inside is male ports, and male ports entirety becomes round table-like.
Above-mentioned metal nuts, moulding, metal cap, silica gel sealing ring, high-voltage insulation cap, metal nuts are sleeved on conductive copper bar successively, and after assembling, the parts being located thereon portion are fixed by the metal nuts of conductive copper bar both sides; Silica gel sealing ring is between metal cap and high-voltage insulation cap, and the side of silica gel sealing ring extends and embeds in the gap between conductive copper bar and metal cap.
The male ports top of above-mentioned high-voltage insulation cap inside is connected with conductive copper bar dimensional fits, and male ports bottom is fixed with metal nuts, and after assembling, metal nuts compresses the insulation crust of high-voltage insulation cap.
Above-mentioned two groups of terminals share a set of moulding, and moulding is made up of two boss, and boss center is provided with the cylindrical hole of different size from top to bottom, and the section between two boss becomes U-lag shape.
Beneficial effect of the present invention: one is by arranging high-voltage insulation cap, and the cylindrical insulation crust shape and structure of high-voltage insulation cap concavity, can conserve space, add insulation distance, withstand voltage level between conductive copper bar and metal cap is improved greatly, has stopped the phenomenon that between conductive copper bar and metal cap, arcing is discharged; Two is the designs of moulding integrative-structure, and realizing two groups of terminals and share a set of moulding, is all insulating material before two groups of terminals, reduces the area that the metal cap of capacitor external conductive copper bar surrounding is exposed, reduces the rate of failure of arcing electric discharge; Three is the U-lag designs between two boss of moulding, and waterproof and dustproof is effective, can reduce because external dust or rainwater cause the rate of failure of short circuit.
