A holder body integrally formed of an insulating member and a support formed with a locking claw for stopping; and a first electrode member provided on the first electrode mounting portion and having elasticity and pressed against a peripheral surface of the battery. And an elastic second electrode member provided on the second electrode mounting portion and pressed against the lower surface of the battery.

[0005] When a disc-shaped button battery is inserted obliquely from above the holder body toward one side, for example, the first electrode member side,
The front side is inserted between the locking pawls of the columns on both sides of the first electrode member and the bottom plate, and the rear lower surface contacts the upper surfaces of the locking claws on both sides of the second electrode member on the other side. When the battery is pushed in, the front peripheral surface is elastically pressed against the first electrode member while the outer peripheral edge on the upper surface front side is locked by the locking claw on the first electrode member side.
When the battery is further pushed in, the bottom and the rear of the peripheral
The upper surfaces of the locking claws of the columns on both sides of the electrode member are pushed to spread and push these columns, the lower surface is elastically pressed against the second electrode terminal, and the rear side of the upper peripheral edge is locked by the locking claws. . When the lower surface is in contact with the bottom plate, the peripheral edge of the upper surface is locked by each locking claw, the peripheral surface is in contact with each column, and is accommodated in the holder body, and the first electrode member is connected to the peripheral surface of the battery (positive electrode). ), The second electrode members are elastically pressed against the lower surfaces to be electrically connected. As a result, the battery is stored in the battery holder in such a manner that it cannot deviate.

a and is flush with the bottom plate 21.

The operation will be described below. As shown in FIG. 5A, in the battery 30, the upper surface 31 and the peripheral surface 32 have a positive (+) pole,
The lower surface 33 is a negative (-) pole. When the battery 30 is inserted obliquely above the holder body 2 toward the electrode terminal 3, the front side enters between the locking claws 24 a, 25 a of the columns 24, 25 on both sides of the electrode terminal 3 and the bottom plate 21. The rear lower surface 33 abuts against the upper surfaces of the locking claws 26b and 27b of the columns 26 and 27.

When the battery 30 is pushed in, as shown in FIG.
The front side of the peripheral surface 32 is elastically pressed against the contact portion 3d of the electrode terminal 3 in a state where the outer peripheral surface 32 is locked by 5b. When the battery 30 is further pushed in, the lower surface 33 and the rear surface of the peripheral surface 32 slide on the tapered upper surfaces of the locking claws 26b, 27b of the columns 26, 27 on both sides of the electrode terminal 4 while sliding these columns 26, 2
7, the lower surface 33 is elastically pressed against the contact portion 4d of the electrode terminal 4, and the lower surface 33 is
And the peripheral edge of the rear side of the upper surface 31 is engaged with the locking claws 26b, 2
7b. The contact portion 4c is housed in the slit 21a of the bottom plate 21 and is flush with the bottom plate 21.

The contact portion 4d of the electrode terminal 4 is elastically pressed against the lower surface 33 (negative electrode) and electrically connected to the (positive electrode). In this manner, the battery 30 is accommodated in the battery holder 1 so as not to deviate.

When the battery 30 is removed from the battery holder 1, two locking claws on one side, for example, locking claws 24 b and 25 b on both sides of the electrode terminal 3 are moved outward against the elasticity of the columns 24 and 25. When the battery 30 is spread and released from engagement with the peripheral edge of the upper surface 31 of the battery 30, the battery 30 is pushed out of the holder body 2 by the spring force of the contact portion 4 d of the electrode terminal 4. Thereby, the battery 30 can be easily taken out from the battery holder 1.
