がある。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealed lead-acid battery,
In particular, it relates to a sealed lead-acid battery having an improved pole. 2. Description of the Related Art In recent years, sealed lead-acid batteries have been required to have a high volume density as a power source for cordless products and as a backup power source for computers and the like. One way to meet this requirement is to reduce the space between the electrode and the lid. A conventional sealed lead-acid battery will be described below with reference to the drawings. In FIG. 4, 1 is an electrode group, 3 is a battery case, 4 is a lid, 5 is a rubber packing (hereinafter abbreviated as rubber packing) such as an O-ring for sealing between the pole 6 and the through hole 4b of the lid. 7 is a bonding agent to be filled in the bonding groove 4a of the lid;
Is an adhesive for filling the pole 4 and the lid 4 by flowing into the recess 4c of the lid. [0004] The sealed lead-acid battery configured as described above will be described below. First, the pole 6 is welded to the electrode plate group 1 and housed in the battery case 3. Bonding agent 7 on lid 4
Is filled in the joint groove 4a of the lid. Then, the pole 6 of the electrode plate group 1 that has entered the battery case 3 penetrates into the through hole 4b of the lid,
The battery case 3 and the cover 4 are joined by fitting the battery case upper edge 3a into the joint groove 4a of the cover. The rubber packing 5 is inserted between the pole 6 and the through hole 4b of the lid to create a sealed state, and finally, the adhesive 8 flows into the concave portion 4c of the lid to be completely sealed. [0005] However, in the above-mentioned conventional configuration, in order to achieve a hermetic seal between the pole 6 and the rubber packing 5, as shown in FIG. Also, the inner diameter of the packing 5 needs to be reduced, and the length of the pole 6 needs to be increased since the filling adhesive 8 needs to be inserted. For these reasons, there is a drawback that the rubber packing 5 is difficult to insert. An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a sealed lead-acid battery which facilitates insertion of a rubber packing. [0007] In order to solve this problem, the present invention provides a battery case in which an electrode group having a cylindrical pole is inserted;
A lid having a joint groove fitted to the upper edge of the battery case, a pole and a lid
O-ring packing inserted between the through hole
In sealed lead-acid battery was example, a position facing the through hole of the lid portion (pole of requiring sealing of pole packing instrumentation
(Position where it is attached) The diameter above the part of the pole that needs to be sealed is made smaller than the inner diameter of the packing,
The diameter of the pole at the mounting position is constant and the packing inner diameter
To make it bigger. With this configuration, the sealed lead-acid battery of the present invention has almost no resistance while the rubber packing is inserted into the small diameter portion of the pole (the portion having a diameter equal to or less than the inner diameter of the rubber packing). The part that needs to be sealed (the position facing the through hole of the pole post) , ie, the pole
Although the diameter is larger than the inner diameter of the rubber packing, the portion inserted here is extremely short, so that the rubber packing can be inserted with a momentary resistance. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A sealed lead-acid battery according to one embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes an electrode group;
a is a portion of the pole above the position corresponding to the through hole 4b of the cover of the pole 2 having a diameter equal to or smaller than the inner diameter of the rubber packing 5 (hereinafter abbreviated as a small diameter portion of the pole). Lid 5, pole column 2
And rubber through-hole 4b of the lid, 7 is a bonding agent to fill the joint groove 4a of the lid, 8 is a recess 4c of the lid.
Is an adhesive for sealing the pole 2 and the lid 4 that have flowed. The sealed lead-acid battery constructed as described above will be described in detail below. First, the pole 2 is provided with a small-diameter portion 2 a of the pole, is welded to the electrode plate group 1, and is housed in the battery case 3. The joining agent 7 is filled in the joining groove 4a of the lid. The pole 2 of the electrode group 1 that has entered the battery case 3 penetrates the through hole 4b of the cover, and the battery case 3 and the cover 4 are joined by fitting the battery case upper edge 3a into the joining groove 4a of the cover. are doing. The O-ring-shaped rubber packing 5 is sequentially inserted from the small-diameter portion 2a of the pole and is inserted to a position facing the through hole 4b of the lid . This position
The diameter of the pole 2 is larger than the inner diameter of the rubber packing 5
The rubber packing 5 is expanded and sealed
A state is created. Finally, the sealing adhesive 8 is applied to the recess 4 of the lid.
c to make a completely closed state . As described above, according to the present embodiment, when the rubber packing 5 is inserted through a portion having a diameter smaller than the inner diameter of the rubber packing 5 (the small-diameter portion 2a of the pole), including the insertion start. Insertion can be performed with almost no resistance, and insertion into the portion of the pole pole lid requiring sealing is very short, so that it is inserted with a momentary resistance. As is apparent from the above description of the embodiment, the sealed lead-acid battery of the present invention has a structure in which the upper portion of the pole is made to have a diameter equal to or smaller than the inner diameter of the rubber packing. A sealed lead-acid battery that can be easily inserted can be realized. Even if the core of the pole is slightly displaced, the rubber packing is easier to insert than before, and the downward pressing operation and the expanding operation at the insertion start part are separated, so that it is possible to concentrate on the downward pressing operation, so that mechanization is easy, etc. Has the effect.
