Description
【考案の詳細な説明】
本考案は電池接続端子として使用する円錐コイルスプリ
ングの構造に関するものである。[Detailed Description of the Invention] The present invention relates to the structure of a conical coil spring used as a battery connection terminal.
電池を電池ケースに固定する場合、第１図に示すように
、電池１の十極は電池ケース２に固定した板バネ３に接
触させ、−極は電池ケースに固定したコイルスプリング
４に接触せしめていた。When fixing the battery to the battery case, as shown in Fig. 1, the ten poles of the battery 1 are brought into contact with the leaf spring 3 fixed to the battery case 2, and the - pole is brought into contact with the coil spring 4 fixed to the battery case. was.
ところで、このコイルスプリング４の形状は第２図に示
すように円錐状に形成されており、その小径端を電池の
一極に接触させ、大径端を第１図の電池ケース２と一体
に形成されたカギ状リブ２ａで挟持し固定している。By the way, the coil spring 4 is formed into a conical shape as shown in FIG. 2, and its small diameter end is brought into contact with one pole of the battery, and its large diameter end is integrated with the battery case 2 shown in FIG. It is clamped and fixed by the formed key-shaped ribs 2a.
しかし、この種のコイルスプリング４は第３図の如く電
池１を傾斜させて装着しようとすると、小径端が滑りや
すく、又、固定側の大径部の曲げ剛性が小径部に較べ小
さい為、根元より大きく曲がり第３図の如く座屈しやす
い欠点がある。However, when this type of coil spring 4 is installed with the battery 1 tilted as shown in Fig. 3, the small diameter end tends to slip, and the bending rigidity of the large diameter part on the fixed side is smaller than that of the small diameter part. It has the disadvantage that it bends more than the base and is prone to buckling as shown in Figure 3.
本考案の目的は座屈しにくい形状で、しかも容易に電池
ケースに装着固定可能な接続端子を得ることにある。The object of the present invention is to obtain a connecting terminal which has a shape that is resistant to buckling and which can be easily attached and fixed to a battery case.
このため本考案は第４図に示すようにコイルスプリング
４を逆円錐とし、大径部４ａを電池の極に接触させ、小
径部４ｂを固定するようにする。Therefore, in the present invention, as shown in FIG. 4, the coil spring 4 is made into an inverted cone, with the large diameter part 4a in contact with the battery pole and the small diameter part 4b fixed.
又、小径部４ｂをそのまま電池ケースに装着するのは困
難であるので、小径部に外周方向に拡がる巻部４Ｃを設
け、大径にして従来通りの装着を可能にした。Furthermore, since it is difficult to attach the small diameter portion 4b to the battery case as it is, the small diameter portion is provided with a winding portion 4C that expands in the outer circumferential direction to make it larger in diameter and allow for conventional mounting.
第５図は本考案のコイルスプリングを電池ケースに装着
する状態を示すもので、電池を傾斜して挿入しても、大
径部４ａは曲げ剛性が小さい為大きく曲がり、電池の一
極に密着する為すべりにくくなる。Figure 5 shows the state in which the coil spring of the present invention is attached to the battery case. Even if the battery is inserted at an angle, the large diameter part 4a bends greatly due to its low bending rigidity and sticks closely to one pole of the battery. This makes it less slippery.
しかも、固定側が小径部４ｂになっており、曲げ剛性大
の為、座屈現象が発生しない。Moreover, since the fixed side is the small diameter portion 4b and has high bending rigidity, buckling does not occur.
又、固定側が小径のままであると電池ケース２への固定
が困難であるので、小径部より大径にすべく半径方向に
広がる数巻のウズ巻状の巻部４Ｃを設けたので電池ケー
ス２に挟持固定しやすい。In addition, if the fixed side remains small in diameter, it will be difficult to fix it to the battery case 2, so we provided several spiral-shaped windings 4C that spread in the radial direction to make the diameter larger than the small diameter part, so the battery case 2. Easy to clamp and fix.
したがって本考案によれば、座屈しない、しかも取付作
業性が悪くならずコストも変らない所望のコイルスプリ
ングが得られた。Therefore, according to the present invention, a desired coil spring that does not buckle, does not deteriorate installation workability, and does not change cost.
特にコイルスプリングのコストは、その形状が自動機で
可能か否かで大きく左右されるので、小径端の固定をウ
ズ巻状に数回の巻部を設けて大径となしたもので、その
実用的効果は大きいものである。In particular, the cost of a coil spring is largely determined by whether the shape can be created using an automatic machine or not. The practical effects are significant.
