Abstract
The utility model discloses a kind of oil immersion type high-voltage and current-limitation fuse oil-leakage-prevention assembly; The purpose of this utility model is to provide a kind of oil immersion type high-voltage and current-limitation fuse oil-leakage-prevention assembly preventing oil immersion type high-voltage and current-limitation fuse leakage of oil; It comprises screw and nut, described screw comprises pedestal, screw rod is extended with facing up of pedestal, nut coordinates with screw rod, have a screwed hole in the center at the back side of pedestal, screwed hole extends upwardly to inside screw, and the center line of the center line of screwed hole and screw rod on the same line, be provided with the seal groove of annular at the back side of pedestal, seal groove is positioned at the outside of inner bolt hole; It has the features such as structure is simple, reasonable in design and easy to use.
Description
Technical field
The utility model relate to a kind of screw, especially a kind of oil immersion type high-voltage and current-limitation fuse oil-leakage-prevention assembly.
Background technology
Oil immersion type high-voltage and current-limitation fuse is simple protective device, it is used for protecting electric equipment from overload and the infringement of short circuit current, the outer sleeve of existing oil immersion type high-voltage and current-limitation fuse is provided with the conducting strip that runs through outer sleeve sidewall, one end of conducting strip is connected with conductive ring, the other end is connected with nut, but this connected mode also exists Leakage in use, conducting strip on oil immersion type high-voltage and current-limitation fuse and conductive ring junction have gap, pass through sealant sealing, but sealing effectiveness is bad, oil can enter oil immersion type high-voltage and current-limitation fuse inside via gap, damage is caused to oil immersion type high-voltage and current-limitation fuse.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of oil immersion type high-voltage and current-limitation fuse oil-leakage-prevention assembly preventing oil immersion type high-voltage and current-limitation fuse leakage of oil.
In order to achieve the above object, a kind of oil immersion type high-voltage and current-limitation fuse oil-leakage-prevention assembly designed by the utility model, it comprises screw and nut, described screw comprises pedestal, screw rod is extended with facing up of pedestal, nut coordinates with screw rod, a screwed hole is had in the center at the back side of pedestal, screwed hole extends upwardly to inside screw, and the center line of the center line of screwed hole and screw rod on the same line, be provided with the seal groove of annular at the back side of pedestal, seal groove is positioned at the outside of inner bolt hole.
Conveniently process, the seal groove of described annular is circular seal groove.
Oil immersion type high-voltage and current-limitation fuse oil-leakage-prevention assembly of the present utility model, oil immersion type high-voltage and current-limitation fuse oil-leakage-prevention assembly coordinates with the screw rod on the outer sleeve of oil immersion type high-voltage and current-limitation fuse, and the sealing ring be arranged in seal groove can prevent the gap between the screw rod of fluid on oil immersion type high-voltage and current-limitation fuse oil-leakage-prevention assembly and outer sleeve from entering oil immersion type high-voltage and current-limitation fuse inside; Therefore, it has the features such as structure is simple, reasonable in design and easy to use.
