As shown in the first diagram, this kind of conventional sealing device has a battery case b of a storage battery a.
The terminal portion e of the pole post E is passed through the pole post insertion hole D formed in the cover plate c, which is airtightly crimped with heat sealing or adhesive to the peripheral wall and partition wall of the cover plate c. Intermediate inner circumferential portion f of inner circumferential wall surface F of pole column insertion hole D
There is a storage battery terminal sealing device of the type in which an annular packing h is interposed between the terminal part e of the pole pole E and a protruding flange g protruding from the outer peripheral surface of the pole pole. Since there is a small annular gap i between the column insertion hole D, that is, the inner circumferential wall surface F of the cover plate c, the terminal portion e of the pole column E is deflected by impact, vibration, etc., and therefore the outer circumference is packed h. The degree of sealing becomes uneven, and there is a risk of electrolyte leaking from areas where the sealing performance is poor.

The shape of the pole column insertion hole 4 of the cover plate 3, that is, the cross-sectional shape of its inner peripheral wall surface is a truncated conical shape that becomes smaller in diameter toward the upper end, that is, the shape of the inner peripheral surface that slopes downward. The hole diameter of the inner peripheral portion 8b is formed to be slightly smaller than the diameter of the terminal portion 5a of the pole column. Thus, when inserting the terminal portion 5a of the pole post 5 into the tapered insertion hole 4 of the cover plate 3, the O-ring on the lower surface of the inclined intermediate inner circumferential portion 8a of the downwardly inclined inner circumferential wall surface 8 is inserted. 6 is pressed against the protruding flange 7 on the lower surface to provide a strong seal, and the terminal portion 5a is pressed against the minimum diameter of the upper end of the insertion hole 4 to protrude outward, and the outer peripheral surface of the terminal portion 5a is is held in pressure contact with the upper inner circumferential portion 8b of the inner circumferential wall surface 8 of the cover plate 3, and at the same time, the pole post 5 is pressed against the inner circumferential portion 8b of the lower end of the cover plate 3 with the circumferential step 7a of the protruding flange 7 on the outer circumference. 8c
The pole pillar 5 is brought into contact with and locked to the cover plate 3.
is fixed by pressure contact at two points at the upper and lower parts of the inner circumferential wall surface 8,
A sealing device that is stable and robust against shocks, vibrations, etc. is provided. In the drawings, reference numeral 9 denotes a protective wall that surrounds the outer periphery of the terminal portion 5a projecting to the outside of the cover plate 3 and projects upwardly from the upper surface of the cover plate 3 higher than the top surface of the terminal portion 5a. The terminal portion 5a is protected from being exposed to direct external force by being hit by equipment or the like from the outside. Reference numeral 10 indicates a notch provided at the upper end edge of the protective wall 9, and the notch 10 serves as an insertion portion when connecting the tip of the connecting wire to the pole terminal portion 5a, and after the connection. This helps prevent the connecting wire from rotating. Preferably, the width of the gap is suitable for holding the connecting wire. As is clear from FIG. 3, it is preferable to provide a plurality of cutouts 10 so that the direction in which the connecting wires are led can be arbitrarily selected.
