りも格段に向上する。As described above, the lower end 4 of the terminal piece 1 having the flange 2 at the lower part and the upper end 8 of the pole column 5 having the flange 6 at the upper part are made liquid-tight in the through hole 10 of the resin piece 9. This is because the terminal pole post 13 with a resin piece formed by resistance welding is welded to the electrode plate group 14, and the lower surface of the cover hole 17 through which the terminal piece 1 passes through and the upper surface of the resin piece 9 are thermally welded. , terminal pole post 1 with resin assembly
3, it is not necessary to have high machining precision as required when forming the conventional resin-wound terminal, and therefore it is possible to improve productivity and reduce costs. In addition, the flanges 2 and 6 are firmly attached to the resin piece 9 due to the caulking effect of the pressing force of the electrodes 18 and 18' applied when resistance welding the terminal piece 1 and the pole post 5, so the resin piece 9 In combination with the thermal welding of the lid 16, the liquid tightness of the terminal portion is significantly improved compared to conventional products.
