【発明が解決しようとする課題】
上記従来例の電池収納構造は乾電池を挿入した時、トーションバネから成る陰極端子が乾電池の陰極に押されて回動することにより、乾電池が円滑に収納される。そして、該陰極端子の構造は、陽極側を先に挿入しても、該陰極端子が回動することにより、乾電池の陰極側が円滑に挿入でき、該陰極端子が破損することもない。
【００１２】
然しながら、前記陰極端子は前記乾電池が挿入された時、該陰極端子の先端部が左右壁部の外方に回動するため、該左右壁部の外方に該陰極端子の先端部が回動するためのスペースを確保する必要がある。そのため、前記陰極端子を用いる場合、該スペースを確保することが前記電池収納構造の小型化の障害になっている。
【００１３】
そこで、電池収納構造に於て、電池収納空間を形成する両端壁部外方の陰極端子回動スペースを不要にして、電池収納構造の小型化を図るために解決すべき技術的課題が生じてくるのであり、本発明はこの課題を解決することを目的とする。
【００１４】
【課題を解決するための手段】
本発明は上記目的を達成するために提案されたものであり、電池収納空間を形成する両端壁部に乾電池の陽極と接する陽極端子と、陰極と接する回動自在の陰極端子とを夫々備え、該陰極端子は両端にコイルバネを有し中央部に突設部を有するトーションバネで形成されて成る電池収納構造に於て、前記陰極端子の前記突設部を側面視くの字状に屈曲させて形成し、且つ、該屈曲部の角度を鈍角に形成し、該陰極端子の前記両端壁部外方への回動を規制するように構成した電池収納構造、
及び、電池収納空間を形成する両端壁部に乾電池の陽極と接する陽極端子と、陰極と接する回動自在の陰極端子とを夫々備え、該陰極端子は両端にコイルバネを有し中央部に突設部を有するトーションバネで形成されて成る電池収納構造に於て、前記陰極端子の前記突設部を側面視くの字状に屈曲させて形成し、且つ、該屈曲部の角度を鈍角に形成し、該陰極端子の前記両端壁部外方への回動を規制するように構成し、更に、前記電池収納空間を形成する底部の前記陰極端子近傍に、該陰極端子の突設部先端部を係止するための突片を形成し、乾電池が収納されていない状態で該突設部先端部が該突片に係止されるように構成した電池収納構造を提供するものである。
【００１５】
【発明の実施の形態】
以下、本発明の一実施の形態を図１乃至図４に従って詳述する。尚、説明の都合上、従来例と同一構成部分については同一符号を付してその説明を省略する。
【００１６】
図１乃至図３に於いて、２２は電池収納構造であり、該電池収納構造２２は従来例の陰極端子（図５に於て１５及び２１）に代えて後述する陰極端子２３及び２４を用いるものであり、該陰極端子２３，２４は同形状を有するため陰極端子２３について説明すると、該陰極端子２３は、中央部に線条のＵ字形突設部２５が突設され、該突設部２５の両端にコイルばね２６，２６が形成され、該コイルバネ２６，２６の両端に所定長さの線条の係止部２７，２７が延びており、該係止部２７が金具１４に係止されている。
【００１７】
更に、前記突設部２５は左方に突設する如く側面視くの字状に折曲され、且つ、該折曲部２５ａを鈍角に折曲され、該突設部２５の先端部２５ｂは前記電池収納構造２２の底部５に形成された孔５ａの下方に延びている。
【００１８】
そして、該孔５ａの周縁部には長方形状の突片５ｂが右方に突設する如く形成されており、乾電池２が収納されない状態で、前記突設部２５の先端部２５ｂが該突片５ｂに係止され、該突設部２５が保持されるように構成されている。
【００１９】
一方、前記陰極端子２４も前記陰極端子２３と同様に形成されると共に、該陰極端子２４近傍の底部５の孔（図示せず）の周縁部にも前記突片５ｂ同様の突片（図示せず）が形成されている。

【００２１】
或いは、前記乾電池２の陽極２ａ側を先に挿入し、次に、陰極２ｂを挿入した場合も、該陰極２ｂの挿入動作により前記突設部２５は、該突設部２５の基端部２５ｃを支点として図に於て反時計回りに回動し、乾電池２は円滑に収納される。そして、この時、該突設部２５の先端部２５ａが前記突片５ｂから離間して右方へ回動するが該先端部２５ｂは前記右壁部７よりも右方に回動することはない。即ち、前記陰極端子２３を用いた構成に於て、陰極２ｂ、陽極２ａのいずれを先に挿入しても同様に円滑に収納される。
【００２２】
又、前記乾電池３を前記電池収納空間４内に収納する時も向きを代えて前記乾電池２同様に収納できる。そして、該乾電池３の収納時の陰極３ｂの挿入動作により前記陰極端子２４の突設部（図示せず）の先端部（図示せず）が左方へ回動するが該先端部は左壁部６よりも左方に回動することはない。
【００２３】
斯くして、乾電池２，３を収納した時、前記陰極端子２３，２４の突設部の先端部は前記左右壁部６，７よりも外側に回動しないため、該左右壁部６，７の外方に前記陰極端子２３，２４の回動スペースを設ける必要がなく、電池収納構造の小型化を図ることができる。
【００２４】
尚、本発明は、本発明の精神を逸脱しない限り種々の改変を為すことができ、そして、本発明が該改変されたものに及ぶことは当然である。
【００２５】
【発明の効果】
本発明は上記一実施の形態に詳述したように、請求項１記載の発明は陰極端子がトーションバネで形成されて成る電池収納構造に於て、前記陰極端子の突設部を側面視くの字状に屈曲させて形成し、且つ、該屈曲部の角度を鈍角に形成し、該陰極端子の電池収納空間両端壁部外方への回動を規制するように構成したので、該両端壁部の外方に前記陰極端子の回動スペースを設ける必要がなく、電池収納構造の小型化を図ることができる。
【００２６】
又、請求項２記載の発明は、陰極端子がトーションバネで形成されて成る電池収納構造に於て、前記陰極端子の突設部を側面視くの字状に屈曲させて形成し、且つ、該屈曲部の角度を鈍角に形成し、該陰極端子の電池収納空間両端壁部外方への回動を規制するように構成し、更に、前記電池収納空間を形成する底部の前記陰極端子近傍に、該陰極端子の突設部先端部を係止するための突片を形成し、乾電池が収納されていない状態で該突設部先端部が該突片に係止されるように構成したため、請求項１記載の発明の効果に加え、乾電池が収納されていない状態で該突設部先端部が確実に前記突片に係止されて、前記陰極端子が安定して保持されると共に、これによって乾電池の収納も容易である等、正に著大なる効果を奏する発明である。

[Problems to be solved by the invention]
In the conventional battery storage structure, when a dry battery is inserted, the cathode terminal formed of a torsion spring is pushed by the cathode of the dry battery and pivots, so that the dry battery is smoothly stored. The structure of the cathode terminal allows the cathode side of the dry battery to be smoothly inserted by rotating the cathode terminal even if the anode side is inserted first, and the cathode terminal is not damaged.
[0012]
However, when the dry battery is inserted, the tip of the cathode terminal pivots outward of the left and right walls, so that the tip of the cathode terminal pivots outward of the left and right walls. It is necessary to secure space for Therefore, when the cathode terminal is used, securing the space is an obstacle to downsizing the battery housing structure.
[0013]
Therefore, in the battery storage structure, there is a technical problem to be solved in order to reduce the size of the battery storage structure by eliminating the necessity of a cathode terminal rotation space outside both end walls forming the battery storage space. Therefore, an object of the present invention is to solve this problem.
[0014]

The present invention has been proposed to achieve the above-described object, and includes an anode terminal in contact with an anode of a dry battery on both end walls forming a battery storage space, and a rotatable cathode terminal in contact with a cathode, respectively. In the battery housing structure formed of a torsion spring having a coil spring at both ends and a projecting portion at the center thereof, the cathode terminal is formed by bending the projecting portion of the cathode terminal into a letter shape as viewed from the side. A battery housing structure formed so that the angle of the bent portion is obtuse, and the rotation of the cathode terminal to the outside of the both end wall portions is restricted;
An anode terminal in contact with the anode of the dry battery and a rotatable cathode terminal in contact with the cathode are provided on both end walls forming the battery housing space, and the cathode terminal has coil springs at both ends and protrudes from the center. In the battery housing structure formed of a torsion spring having a portion, the projecting portion of the cathode terminal is formed by bending in a side view-like shape, and the angle of the bent portion is formed to be obtuse. The cathode terminal is configured to restrict the outward rotation of the both end wall portions, and furthermore, a protruding portion tip of the cathode terminal is provided near the cathode terminal on the bottom forming the battery housing space. The present invention provides a battery accommodating structure in which a projecting piece is formed for locking the protruding portion, and the tip of the projecting portion is locked to the projecting piece in a state where the dry battery is not stored.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. For convenience of description, the same components as those of the conventional example are denoted by the same reference numerals, and description thereof will be omitted.
[0016]
1 to 3, reference numeral 22 denotes a battery housing structure. The battery housing structure 22 uses cathode terminals 23 and 24 described later instead of the conventional cathode terminals (15 and 21 in FIG. 5). Since the cathode terminals 23 and 24 have the same shape, the cathode terminal 23 will be described. The cathode terminal 23 is provided with a U-shaped projecting portion 25 having a linear shape at the center thereof. Coil springs 26, 26 are formed at both ends of the coil spring 25, and linear locking portions 27, 27 of a predetermined length extend at both ends of the coil springs 26, 26, and the locking portions 27 are locked to the metal fitting 14. Have been.
[0017]
Further, the protruding portion 25 is bent in a shape like a side view so as to protrude to the left, and the bent portion 25a is bent at an obtuse angle. It extends below a hole 5 a formed in the bottom 5 of the battery housing structure 22.
[0018]
A rectangular protruding piece 5b is formed on the periphery of the hole 5a so as to protrude rightward. When the dry battery 2 is not stored, the tip 25b of the protruding part 25 is connected to the protruding piece. 5b so that the protruding portion 25 is held.
[0019]
On the other hand, the cathode terminal 24 is also formed in the same manner as the cathode terminal 23, and a protrusion (not shown) similar to the protrusion 5b is also formed on the periphery of a hole (not shown) in the bottom 5 near the cathode terminal 24. Are formed.
[0020]
Thus, when storing the dry battery 2 in the battery storage space 4, the lid 10 is removed, and the anode 2a side of the dry battery 2 faces the anode terminal 13 side, and the cathode 2b side of the dry battery 2 With the cathode 2b side of the dry battery 2 inserted first, and the anode 2a side of the dry battery 2 inserted while pressing the cathode 2b against the cathode terminal 23 side. Are stored in the battery storage space 4. At this time, as shown in FIG. 4, the projecting portion 25 of the cathode terminal 23 rotates counterclockwise in the drawing with the base end 25c of the projecting portion 25 as a fulcrum, and the projecting portion 25 The distal end portion 25b separates from the protruding piece 5b and rotates rightward, but the distal end portion 25a does not rotate rightward than the right wall portion 7 due to the above-described shape of the protruding portion 25. .
[0021]
Alternatively, even when the anode 2a side of the dry battery 2 is inserted first, and then the cathode 2b is inserted, the projecting portion 25 is formed by the insertion operation of the cathode 2b so that the base end 25c of the projecting portion 25 is formed. Is rotated counterclockwise in the figure with the fulcrum as a fulcrum, and the dry battery 2 is smoothly stored. At this time, the distal end portion 25a of the protruding portion 25 separates from the protruding piece 5b and rotates to the right. However, the distal end portion 25b does not rotate to the right of the right wall portion 7. Absent. That is, in the configuration using the cathode terminal 23, even if any one of the cathode 2b and the anode 2a is inserted first, it is stored smoothly similarly.
[0022]
Also, when the dry battery 3 is stored in the battery storage space 4, it can be stored in the same manner as the dry battery 2 by changing the direction. The distal end (not shown) of the protruding portion (not shown) of the cathode terminal 24 is rotated leftward by the insertion operation of the cathode 3b when the dry battery 3 is stored, but the distal end is located on the left wall. It does not rotate to the left than the part 6.
[0023]
Thus, when the dry batteries 2 and 3 are stored, the tips of the protruding portions of the cathode terminals 23 and 24 do not rotate outside the left and right walls 6 and 7, so that the left and right walls 6 and 7 are not rotated. There is no need to provide a rotating space for the cathode terminals 23 and 24 outside the above, and the size of the battery housing structure can be reduced.
[0024]
The present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified ones.
