Abstract

PURPOSE:To prevent the seal material flowed on the surface and to make clear the code provided on the fornt, by performing the heat treatment through mating the cover on the opening of the case after thermally molten agent is inserted in the ring shaped grooves provided at the cover, in manufacturing the seal type electirc equipment such as electromagnetic relays. CONSTITUTION:The ring shaped grooves 3 are formed at the surrounding of the cover 2 mated to the opening 5 of the case 1, and the thermally molten agent 4 is mated to the ring shaped grooves 3. Further, after inserting the thermally molten agent 4 is inserted, the cover 2 is mated to the opening 5 of the case 1 and the cover 2 is held with the ring shaped step 6. With this condition, ultrasonic wave operation is made to seal the cover 2 at the opening 5 of the case 1 with thermally melting the thermally molten agent 4. The thermal adhesives 4 in this operation are sectioned into a plurality of section chips to mate them to the ring shaped grooves 3 of the cover 2. Further, the positioning latch 7 for the cover 2 is formed inside wall of the opening of the case 1 to make easy mating between the cover 2 and the opening 5.
