It consists of an oblong plate with a length that can be inserted into
It is bent downwards so that its upper end can be locked to the ear of the ear group which is arranged outside the electrode group located at one end or the other end housed in the battery case of the storage battery. In this case, it is preferable that the steel sheet is thin and has appropriate elasticity.

Further, the terminal 1 of the present invention has a lower end portion 1b.
At a predetermined position, for example, by bending in a V- shaped cross section as shown in the drawing to form a bent projecting plate portion 2, and the terminals 1 projecting on the outer surfaces of both end walls of the battery case of the storage battery. The bending projecting plate portion 2 is pinched and fixed between the outer surface of the partition wall of the battery case and the inner surface of the surrounding frame in the pulling operation by inserting the bending projection plate portion 2 from above or below into the insertion hole. That is, the lower end side of the terminal 1 is fixed in the surrounding frame by the inserting operation. In the terminal 1, the lower end plate portion 1c extending downward from the bent projecting plate portion 2 may be extended vertically as shown by the alternate long and short dash line in FIG. In this case, the terminal 1
It can be inserted from the upper end or the lower end into the insertion hole of the insertion frame. As shown by the solid line, when the lower end plate portion 1c is bent to one side to form the locking plate portion 1c inclined with respect to the vertical surface, the terminal 1 is inserted into the surrounding frame from below. However, when the terminal 1 is pulled up and pulled up, it can also come into contact with the lower edge of the surrounding frame to act as a stopper.

Next, a more detailed description will be given with reference to FIGS. 4 and 5. Since the terminal 1 of the present invention has the above-mentioned structure, it can be easily mounted in the enclosure of the outer surface of both ends of the battery case of the storage battery, as described in detail below. That is, as clearly shown in FIGS. 4 and 5, by using the storage battery terminal 1 of the present invention, the monoblock battery case C of the storage battery A is integrally formed with a predetermined height on each outer surface of both end walls a, a. The terminal 1 is inserted from below into an insertion hole 4 formed between the outer surface of the end wall a by the protruding surrounding frame 3, which in the illustrated example is a pair of facing L-shaped frames. The upper end portion 1a that has been inserted is grasped and pulled upward, and the bent projecting plate portion 2 having a V-shaped cross section provided on the lower end portion thereof is forcibly accommodated in the surrounding frame 3 and the end wall a It is clamped and fixed between the outer surface and the inner surface of the surrounding frame 3. Thus, the terminal 1 is obtained in a state where it is held by the surrounding frame 3 and the ears of the upper end portion 1a and the long plate portion of a predetermined length extend upward from the stop point. Thus, the upper end 1 of the terminal 1
Since a is bent inward so as to be appropriately hooked on the ear b of the electrode plate group B, one of the ones is arranged at the outermost end of the electrode plate group B located at one end in the battery case C of the storage battery A. The poles of the pole plate of the poles are engaged with the ears b from diagonally above in a contact state. Similarly, the separately prepared terminal 1 of the present invention is inserted into the surrounding frame 3 provided on the opposite side, and the bent projecting plate portion 2 is fixed and held in the surrounding frame 3 in the same manner. The upper end portion 1a is locked to the ear b of the electrode plate ear group of the other pole that is arranged at the outermost end of the electrode plate group B located at the other end in the battery case.

In this case, each terminal 1 has a lower edge of the surrounding frame 3 when the lower end plate portion 1c below the bent projecting plate portion 2 is bent and formed on the inclined plate portion as shown by the solid line in FIG. Since it abuts on the terminal 1, it acts as a stopper when the terminal 1 is pulled upward.

As described above, with the pair of terminals 1 of the present invention set at both ends of the storage battery, the electrodes are inverted by a conventional method by a cast-on casting mold to lead-melt-cast all electrode plate ear groups. Connection by straps, cell-to-cell connection, and terminal connection are performed, then these electrode plate groups B, B, B are pushed into each cell chamber, and then the back surface of the monoblock battery lid is capped to attach the connecting agent. The battery and the lid are airtightly bonded to each other to produce a sealed storage battery.

As shown in FIG. 6, a fitting / locking projection 7 is provided on the outer surface of the end wall a of the battery case C at a position facing the inner surface of the surrounding frame 3 to attach the terminal 1 of the present invention. when inserted into the surrounding frame 3, the fitting <br/> retaining projection 7 is made to lock the fitting in the recess 8 of the back of the V-shaped bent veneer 2, further in its predetermined position It is possible to stop the insertion work of the terminal 1 of
Further, the fixing of the bent projecting plate portion 2 in the surrounding frame 3 can be strengthened. In this case, it is preferable that the upper and lower surfaces of the fitting and locking projection 7 are inclined surfaces 7a, 7a.

7, FIG. 8 and FIG. 9 each show a modified example of the terminal 1 of the present invention, the lower end plate portion 1c of which extends vertically downward, but at both side edges or one side edge thereof. With the locking plate portion 1d protruding from this, when the terminal 1 is inserted into the surrounding frame 3, the upper edge of the locking plate portion 1d engages with the lower surface of the surrounding frame 3. And acts as a stopper.

In the above embodiment, the V-shaped bent projecting plate portion 2 provided on the terminal 1 is bent so that the projecting ridge thereof engages with the inner surface of the surrounding frame 3. However, although not shown, On the contrary, it may be bent and projected so that when the terminal 1 is inserted into the insertion hole 4, the projection of the bent projecting plate portion 2 engages with the outer surface of the end wall a of the battery case C. Of course. Further, instead of the V-shape, a W-shaped double bent projecting plate portion may be used.
