Dry-battery housing

摘要

A dry-battery housing includes an electrode terminal member made of a single wire, a dry-battery housing unit, a flange portion arranged so as to project at first side of the electrode terminal member, a first partition plate projecting along outside for first side of the electrode terminal member, a second partition plate projecting along outside for second of the electrode terminal member, a first fixing plate projecting from the first partition plate toward the second partition plate, a second fixing plate projecting from the second partition plate toward the first partition plate, a flange-root portion including a narrow space portion for allowing insertion and removal of a rim at the first side of the electrode terminal member and an engagement portion arranged between the narrow space portion of the flange-root portion and a border of an opening portion of the dry-battery housing.

主权项

1. A dry-battery housing comprising:
a removable and replaceable electrode terminal member made of a single wire; a dry-battery housing unit that is a hollow portion defined by an opening portion, a side wall portion and a bottom portion; a flange portion that projects from one border toward another border of the opening portion of the dry-battery housing unit, at a first side of the electrode terminal member that is arranged so as to face the side wall portion of the dry-battery housing unit; a first partition plate that projects from the side wall portion of the dry-battery housing unit toward the hollow portion thereof along an outside of the first side of the electrode terminal member that is arranged so as to face the side wall portion of the dry-battery housing unit; a second partition plate that projects from the side wall portion of the dry-battery housing unit toward the hollow portion thereof along an outside of a second side of the electrode terminal member that is arranged so as to face the side wall portion of the dry-battery housing unit, the second side opposing to the first side of the electrode terminal member; a first fixing plate that projects from the first partition plate toward the second partition plate and is independent of the flange portion, the first fixing plate facing a rim portion at the first side of the electrode terminal member that is arranged so as to face the side wall portion of the dry-battery housing unit and fixing the electrode terminal member thus arranged; a second fixing plate that projects from the second partition plate toward the first partition plate and is independent of the first fixing plate, the second fixing plate facing a rim portion at the second side of the electrode terminal member that is arranged so as to face the side wall portion of the dry-battery housing unit and fixing the electrode terminal member thus arranged; a flange-root portion that includes a narrow space portion formed so as to be wide enough to allow insertion and removal of a rim at the first side of the electrode terminal member, the narrow space portion being in parallel with the side wall portion and the first fixing plate; and an engagement portion that is arranged at a space between the narrow space portion of the flange-root portion and the one border of the opening portion of the dry-battery housing unit, the engagement portion fixing a first corner portion of the rim at the first side of the electrode terminal member that is arranged so as to face the side wall portion of the dry-battery housing unit; wherein the electrode terminal member comprises:
a positive terminal portion formed at a first end of the single wire, as a spiral that slightly swells; anda negative terminal portion formed at a second end of the single wire, so as to project as a coil, wherein a width of a spatial area between the first fixing plate and the second fixing plate is made wider at an area heading for the opening portion of the dry-battery housing unit from the negative terminal portion of the electrode terminal member, the area being wide enough to allow the negative terminal portion to project into the hollow portion of the dry-battery housing unit when the electrode terminal member is arranged so as to face the side wall portion of the dry-battery housing unit, wherein the negative terminal portion of the electrode terminal member is arranged so as to face the side wall portion of the dry-battery housing unit and is positioned closer to the opening portion of the dry-battery housing unit, with a tip thereof positioned inside the hollow portion of the dry-battery housing unit by projecting from the area, and the positive terminal portion of the electrode terminal member is arranged so as to face the side wall portion of the dry-battery housing unit and is positioned closer to the bottom portion of the dry-battery housing unit, with a tip thereof positioned outside the hollow portion of the dry-battery housing unit and merely exposed in the area, wherein, for attachment of the electrode terminal member, the rim portion at the first side of the electrode terminal member is firstly inserted in the narrow space portion of the flange-root portion, and subsequently, the rim portion at the first side of the electrode terminal member is inserted in a space between the side wall portion of the dry-battery housing unit and the first fixing plate concurrently with insertion of the rim portion at second side of the electrode terminal member in a space between the side wall portion of the dry-battery housing unit and the second fixing plate,
wherein the first corner portion of the rim at the first side of the electrode terminal member is hooked up on the engagement portion, whereby the electrode terminal member is arranged so as to face the side wall portion of the dry-battery housing unit,wherein, by tilting the first corner portion of the rim at the first side of the electrode terminal member toward an open space between the first fixing plate and the flange portion, the first corner portion of the rim at the first side of the electrode terminal member can be removed from the engagement portion, the first corner potion of the rim at the first side of the electrode terminal member arranged so as to face the side wall portion of the dry-battery housing unit, and wherein the electrode terminal member connects a set of two dry batteries aligned in a depth direction of the dry-battery housing unit when the set of two dry batteries are housed therein.
