Description

  The present invention relates to a dry cell holder for loading a small dry cell into a large predetermined dry cell storage unit.

Many applications have been filed for this type of dry battery holder, such as Japanese Utility Model Laid-Open No. 6-77155 and Japanese Utility Model Laid-Open No. 6-28990.
The reason is that the electrical conductivity between the stored dry battery and the device is significantly inferior to the case of direct use.

  The present invention has been made in view of such circumstances, and it is an object of the present invention to make the energization of a housed small dry battery almost the same as in the case of direct use.

  In order to achieve this object, the dry battery holder of the present invention is a cylindrical case body having a size that fits into the dry battery storage part, and an anode terminal is pierced and held at one end thereof so as to be able to advance and retreat. A spring claw that sandwiches the outer periphery of a small battery with the anode facing the anode terminal is provided inside, and when the small battery is pressed and inserted into the free end of the spring claw toward the anode terminal, its outer periphery A dry battery holder configuration is adopted, in which a guide surface is formed so as to be guided around.

With this configuration, when storing a small dry battery, the spring claw elastically deforms and goes around the outer periphery of the small dry battery, and the anode is pressed against the anode terminal. At the same time, the small dry battery is sandwiched between spring claws. As a result, the anode terminal and the anode of the small battery are held in a state where they are strongly pressed against each other, and the current-carrying property becomes the best state. The anode terminal is in a protruding state and is held by a small battery held by a spring claw.
When the use is finished, the small battery can be pushed out and removed by pushing the anode terminal strongly.

  Furthermore, by adopting a configuration in which the outer periphery of the small dry battery in contact with the anode is removed at the position where the anode terminal is pushed in most, the clamping position by the spring pawl is taken out as follows. Becomes easier. That is, since the spring claw is released by pushing the anode terminal, the small dry battery can be easily removed without receiving resistance by the spring claw.

  And since a small battery to be housed inside is provided with a rib for guiding the spring claw and the working anode terminal, it can be easily inserted into a predetermined position for loading the small battery. .

  Hereinafter, the best embodiment of the present invention will be exemplified, but the present invention is not limited thereto.

(1) The holder body is a cylindrical body having the same diameter as that of the single dry battery, and one end is opened and the other end is closed.
On the inner closed end side of the holder (1), a spring holder that can protrude to the outside and holds the anode terminal (2) so as to be able to advance and retreat, and is integrally molded with spring claws (4a) (4b) (4c) (4) is fitted and fixed.
A detachment prevention disk (2b) is integrally fixed around the inner end (2a) of the anode terminal (2).
The spring claws (4a) (4b) (4c) are arranged so as to surround the anode terminal (2).

The opposing surfaces of the spring claws (4a), (4b), and (4c) are in contact with the clamping surfaces (6a), (6b), and (6c) so as to be in free contact with a virtual circle that is smaller than the diameter of the AA dry battery (B). It is formed.
The top end of the free end (the open end side of the holder body (1)) is positioned in a virtual circle larger than the diameter of the AA dry battery (B), and then the clamping surfaces (6a) (6b) ( 6c) are formed on the guide surfaces (5a), (5b) and (5c) that continue toward 6c).

Three ribs (3a) (3b) (3c) are provided inside the main body (1).
The ribs (3a) (3b) (3c) are for guiding the AA batteries (B) toward the spring claws (4a) (4b) (4c).

When the AA battery (B) is inserted from the open end of the holder (1) with its anode (B1) facing inward, it collides with the apex of the spring claws (4a) (4b) (4c).
In this state, when the AA dry battery (B) is pushed in strongly, the spring claws (4a) (4b) (4c) are pushed and expanded by the guide surfaces (5a) (5b) (5c) while being elastically deformed. The clamping surfaces (6a), (6b), and (6c) come to the outer periphery of the AA battery (B).
As a result, the anode (B1) of the AA battery is strongly pressed against the inner end (2a) of the anode terminal (2), and in this state, the AA battery (B) is secured to the holder body (1). Will be.
That is, the AA dry battery (B) is secured in a state close to integration in a state where the anode (B1) and the anode terminal (2a) are pressed.
The length of the anode terminal (2) is the same as the length from the outer apex to the cathode of the AA dry battery (B) secured in the holder (1) and the length from the anode to the cathode of the single dry battery. It is set to become.

  The protruding lengths of the spring claws (4a), (4b), and (4c) are determined by the size of the AA batteries (B ) Is set so as to be disengaged from the clamping surfaces (6a) (6b) (6c).

In this way, the AA dry battery (B) is released from being clamped by the spring claws (4a), (4b), and (4c) by strongly pushing the anode terminal (2).
In the figure, (S) is a cathode spring of a battery housing part provided in an electric appliance (not shown).

  In the present invention, not only can a small dry battery be used in an electric device of a large dry battery specification, but also the conventional problem of conductivity deterioration can be eliminated.
