PURPOSE:To improve the duarability and to restrict the generation of an instant circuit cutting, by forming steps to compose plural stepped surfaces at guide surfaces of a cell housing, and projecting connections from the stepped surfaces respectively making the height of the connections lower than that of the steps. CONSTITUTION:At the end 2A of a cell housing 2 of a terminal unit 1, a gearing hole 5 to gear with a gearing click 4 of a cell 3 is furnished, and at one side of guide surface 2B, two steps are furnished making a projection 6 and a projection 7 thereover. In the projections 6 and 7, leaf spring type connection terminals 6A and 7A are incorporated as connectors respectively. On the other hand, at the side 3B of the cell 3, sliding surfaces 8 and 9 with steps responding to the projections 6 and 7 are formed, and contact terminal plates 8A and 9A are buried at the sliding surfaces 8 and 9 respectively. In such a composition, the unnecessary contact between connections can be avoided at every insertion and removal, and, the duarability is improved and the generation of an instant circuit cutting can be restricted. |
