Abstract: A lead-free sealing glass and a manufacture method thereof are provided. The lead-free sealing glass includes: 30 wt %-60 wt % of SiO2, 10 wt %-30 wt % of BaO, 1 wt %-5 wt % of Na2O, 1 wt %-10 wt % of K2O, 2 wt %-10 wt % of V2O5, 5 wt %-10 wt % of CaO, 1 wt %-5 wt % of Al2O3, 0 wt %-5 wt % of B2O3, 1 wt %-3 wt % of Fe2O3, and 0-5 wt % of alkaline earth metal oxide.

Abstract: A fuse appliance has a fuse carrier for receiving a fuse and a base. The fuse carrier is in a cavity of the base and is manually operable to remove or insert the fuse. Fixed contacts are provided on the base which engage with moving contacts provided on the carrier. Wiring terminals are electrically connected to the fixed contacts. A rotational-linear pulling operation mechanism has a semicircular rotary shaft structure that has two semicircular convex shafts and first and second circular straight grooves fitted to each other so that the fuse carrier performs rotational and linear movements relative to the base and an interchange between rotational and linear movements at a transition position when the carrier is pulled out of or pushed into the appliance.

Abstract: Disclosed is a fuse appliance, which comprises a fuse carrier for carrying a fuse and a fuse appliance base. The fuse carrier is arranged, in a manually operable way, in a hollow cavity of the fuse appliance base that is formed by buckling and assembling a shell bottom and a shell cover, so as to remove or insert the fuse. Arranged on the two sides of the fuse appliance base are fixed contacts which come into contact with moving contacts arranged on the fuse carrier, and wiring terminals for electrically connecting the two contacts of the fuse appliance with a main circuit respectively.
