It is heated for fixed nut, the easily expansion because nut is heated is fixedly installed to inside specific small space again, so
Nut expanded by heating can then extrude pedestal, if the pedestal of plastic material then can deform pedestal, base of ceramic may press into broken
Split, the stability that strong influence pedestal is used.Therefore, a kind of base of support current-limiting fuse is proposed regarding to the issue above
Seat.
Utility model content
The purpose of this utility model is that the base that a kind of support current-limiting fuse is provided to solve the above problems
Seat.
The utility model is achieved through the following technical solutions above-mentioned purpose, a kind of pedestal of support current-limiting fuse,
Including the first connection contact, the first connection contact side sets second and connects contact, and the first connection contact and the institute
The second connection contact is stated to be installed on pedestal, it is described state the first connection contact be connected with described second contact both sides be all connected with it is solid
Fixed board, fixed plate lower section connection earthenware, and the ceramic tube inside install the first screw, first screw with it is described
Moisture absorption plate is installed in the junction of earthenware, and the second nut is installed in the second connection contact side.
Preferably, in order that the pedestal has more good heat dispersion, radiating is provided with the base outer wall outer
Shell.
Preferably, in order that the wire of the base interior is stably fixed to inside device, not with remaining component phase
Contact, effectively prevents wire heat damage, and the first connection contact is connected with described second and cabling channel is respectively provided with inside contact.
Preferably, in order that the pedestal overall structure is more stablized, the fixed plate side sets draw-in groove, and the card
Connected nail is installed in groove inside, and the fixed plate is fixedly connected the pedestal by connected nail.
Preferably, in order that the water energy of moisture absorption plate absorption enough penetrates into the ceramic tube inside, and with the earthenware
Internal ammonium nitrate reaction, produces the effect of heat absorption, it is to avoid first nut, the second nut expanded by heating, the suction
Damp intralamellar part is provided with water seepage hole, and the ceramic tube inside is filled with ammonium nitrate.
Preferably, in order that the pedestal is more stablized when intraware is supported, the pedestal overall structure is U-shaped knot
Structure.
The beneficial effects of the utility model are：Because current-limiting fuse is in running, device inside produces high temperature, so
Easily cause the pedestal of fuse to be heated, be inconjunction with pedestal and be heated for fixed nut, the easily expansion because nut is heated,
It is fixedly installed to again inside specific small space, so nut expanded by heating can then extrude pedestal, if plastic material
Pedestal then can deform pedestal, and base of ceramic may press into fragmentation.Nut is installed by base interior of the present utility model
Ceramic tube inside fills ammonium nitrate, and installs moisture absorption plate in the junction of nut and earthenware, using moisture absorption plate absorption air
In moisture, and penetrate into ceramic tube inside, ammonium nitrate meets water heat absorption, so as to reduce ceramic tube inside temperature, effectively prevents ceramics
Pipe internal nut thermal expansion extruding causes earthenware to deform, so that increase stability when pedestal is used, and security.Pass through
Heat-dissipating casing is set on the pedestal of device, the heat sinking function of device is effectively increased, it is ensured that base interior component can be stablized to be transported
OK.And device generally ceramic material, with good high-temperature stability, and service life is more long.
