【考案の詳細な説明】
本考案は密閉形電池の安全装置の改良に関するものであ
る。[Detailed Description of the Invention] The present invention relates to an improvement of a safety device for a sealed battery.
従来円筒状密閉形ニッケル・カドミウム電池は、頂部に
陽極端子を兼ねたキャップ１を設け、該キャップ１の空
間部２に弁装置が固有されているが、弁装置はスプリン
グ３、ゴム弁体４等部品数が３乃至４種であるので組立
てに多くの工数を要し、従って製造価格が高価となり、
また弁圧を一定に保つ必要があるためキャップ１に外部
衝撃を加えたり、半田付は等加熱することができない欠
点を有していた。A conventional cylindrical sealed nickel cadmium battery has a cap 1 on the top that also serves as an anode terminal, and a valve device is provided in a space 2 of the cap 1. The valve device includes a spring 3 and a rubber valve body 4. Since the number of parts is 3 or 4, it requires a lot of man-hours to assemble, and therefore the manufacturing price is high.
In addition, since it is necessary to keep the valve pressure constant, it is not possible to apply an external impact to the cap 1, and it is not possible to uniformly heat the cap 1 during soldering.

プリング３が縮小して、ガスは排出孔５から排出される
。In the sealed nickel-cadmium battery shown in FIG. 1, when the internal pressure rises, the rubber valve body 4 rises, the spring 3 contracts, and gas is discharged from the discharge hole 5.
なお６は上蓋、７はカシメバッキング、８は電池罐、９
はＵ字状カシメ肩部、１０は極板群である。Note that 6 is the top lid, 7 is the caulking backing, 8 is the battery can, and 9
1 is a U-shaped caulking shoulder, and 10 is a group of electrode plates.
本考案は上記の如き欠点を除去するもので、カシメ肩の
外側に形成された電池罐の窪部の上面または底面の少な
くとも一方に排気孔を形成すると共に該窪部の板厚を電

プを端子専用とし、製造価格を低廉ならしめるものであ
る。The present invention eliminates the above-mentioned drawbacks by forming an exhaust hole on at least one of the top or bottom surface of the recess of the battery case formed on the outside of the caulking shoulder, and adjusting the plate thickness of the recess to the thickness of the recess of the battery case. By making the cap thinner than the other parts, and by placing a hard spacer in the recess to close the exhaust hole, the cap can be used exclusively for the terminal, and the manufacturing cost can be reduced.
本考案においては、帽体１１は陽極端子のみとなり、Ｕ
字状の窪部１２の上面または底面の少なくとも一方に排
気孔１２を有し、Ｕ字状の窪部１３に、該窪部１３の円
周方向にナイロン等の硬質合成樹脂からなる扁平状のス
ペーサー１４を位置せしめて、電池罐８の上部をカシメ
上蓋６を固定する。In the present invention, the cap body 11 has only an anode terminal, and U
The U-shaped recess 13 has an exhaust hole 12 on at least one of the top or bottom surface of the recess 12, and a flat hole made of hard synthetic resin such as nylon is provided in the U-shaped recess 13 in the circumferential direction of the recess 13. The spacer 14 is positioned and the upper part of the battery can 8 is caulked to fix the upper cover 6.
本考案における電池は、正常状態においては第３図に示
す如く、スペーサー１４により排気孔１２を閉塞してい

若干薄く形成されてＵ字状になっているため、鉄部に応
力が集中して第４図に示す如き形状に変形するので、排
気孔１２が開孔状態となり、ガスは該排気孔１２を通じ
て実線矢印に示す如く外部に排気される。In the battery according to the present invention, as shown in FIG. Since the thickness is slightly thinner than the thickness of the battery case 8 other than the recessed part 13 and has a U-shape, stress concentrates on the iron part and deforms it into the shape shown in FIG. 12 is opened, and gas is exhausted to the outside through the exhaust hole 12 as shown by the solid arrow.
この場合、スペーサー１４は変形せずして、バッキング
としての機能を果している。In this case, the spacer 14 functions as a backing without being deformed.
そしてスペーサー１４は、弾性を有するバッキングが変
形を繰り返すときに伴なうような劣化を起こすことはな
い。Further, the spacer 14 does not suffer from the same deterioration that occurs when an elastic backing undergoes repeated deformation.
次に本考案において、組電池として使用する場合には、
帽体１１を設けなくても電池として十分使用可能である
。Next, in this invention, when used as an assembled battery,
Even without providing the cap body 11, it can be fully used as a battery.
なお本考案は、銀電池、水銀電池、アルカリマンガン電
池、扁平形密閉ニッケル・カドミウム電池等ガス排気を
要する電池に適用し得ることは勿論である。It goes without saying that the present invention can be applied to batteries that require gas exhaust, such as silver batteries, mercury batteries, alkaline manganese batteries, and flat sealed nickel-cadmium batteries.
上述せる如く、本考案は製造部品が少なくなつて製造や
部品管理が容易となり、而も構造が簡単で、安価に製造
することができ、また製品のバラツキを減少せしめるこ
とができる等実用的価値共だ大なるものである。As mentioned above, the present invention has practical value such as fewer parts to be manufactured, easier manufacturing and parts management, simple structure, lower manufacturing cost, and reduced product variation. We are all great together.
