PURPOSE:To simplify the assembly process and to stabilize and improve the working efficiency by composing an insulating terminal by using a base on whose upper side and lower side insulating packings are formed integrally after providing an electrolyte- resisting insulating seal layer with an excellent heatproof and adhesive property, at the peripheral edge of the permeable hole of a lid plate. CONSTITUTION:At the peripheral edge of the permeable hole 2a of a metallic lid plate 2, an insulating layer 3 composed mainly of a fluorine resin and a binder of heatproof and electrolyte-resisting property is provided. Then, an insulating packing layer 4 which consists of a synthetic resin and the like is formed integrally on the upper and the lower surfaces of the lid plate 2 including the surface of the layer 3 and the inner wall surface of the permeable hole 2a, the rivet leg 5 of a terminal rivet 5 is inserted to an insertion hole 4d for the rivet leg on the layer 4 to fasten and fix the tip of the above leg 5a. As a result, the assembly process is simplified to improve the working efficiency, and a sealing plate with insulating terminal is produced. By using such a sealing plate, a sealed alkaline cell with a high airtightness and a high dampproof property is formed. |
