Abstract

PURPOSE:To eject and house a battery easily and smoothly by making one of terminals of a dry battery housing part work as a movable terminal, which is provided with a lock mechanism and of which projecting quantity can be changed. CONSTITUTION:When a dry battery 7 is slid in an arrow direction, a low projection of a member 3 to be locked is separated from the projected inclined surface of a lock member 12 by the member 3 and a spring 4, and a high projection adjacent to the member 3 is turned at a small angle by the spring pressure to push the projected inclined surface of the lock member 12, and the high projection is engaged with the minus terminal 2 side inside of a dry battery housing case 1. The lock of the member 3 is cancelled to make both electrodes of the battery 7 pressure-contact between the minus terminal 2 and a plus terminal 6 to connect them electrically. When the battery 7 is slid in the arrow direction again, since the minus terminal 2 is turned similarly to be locked under the condition that the terminal 2 enters the case 1 a little, the battery 7 can be ejected and housed freely.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to easily and smoothly store and take out dry batteries while connecting positive and negative terminals in a dry battery storage part of a product driven by dry batteries. The present invention relates to a storage structure for dry batteries.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, a ribbon, one end of which is fixed to the upper portion of a dry battery storage portion, intervenes in a gap between the dry battery and the bottom of the storage portion when the dry battery is stored. There is a storage structure in which the end (free end) is exposed to the upper part of the dry battery, and when the dry battery is taken out, the other end of the exposed ribbon is pulled to lift the dry battery from the storage part. ..

[0003]

However, in the case of the conventional structure in which the dry battery is lifted by pulling the ribbon, the free end of the ribbon to be exposed when the dry battery is housed is accidentally pinched under the dry battery, and the dry battery is removed. It is difficult to remove the ribbon, or if the clamping force between the positive and negative terminals is strong, you need to pull the free end of the ribbon strongly when removing the dry battery, but if you pull too hard, the dry battery will pop out and drop. There were challenges.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a dry battery storage structure which can easily and smoothly store and take out a dry battery in order to solve such a conventional problem.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention brings a positive terminal and a negative terminal formed in a dry battery storage portion of a product driven by a dry battery into contact with a positive electrode and a negative electrode of the dry battery. In the structure, either the positive terminal or the negative terminal is constituted by a movable terminal with a variable protrusion amount provided with a lock mechanism, and when the contained dry battery is slid to the movable terminal side, the piston of the movable terminal is moved. By motion, the operation of locking when the protrusion is small and unlocking when the protrusion is large is repeated alternately.When locking, a gap is created between the dry battery and both terminals, making it easy to take out and store the dry battery. I was able to do it.

[0006]

In the battery storage structure configured as described above, the lock mechanism operates when the amount of protrusion of the movable terminal is small due to the piston movement of the movable terminal, and the distance between the positive terminal and the negative terminal is equal to that of the dry battery. It is longer than the length, and when the dry battery is taken out by placing the dry battery in the storage part and sliding it to the movable terminal side once, it operates so that the lock is released and the protruding amount of the movable terminal becomes large. Easily and easily by locking the movable terminal
The battery can be taken out smoothly, and conversely, when it is stored, the dry battery is placed in the storage portion, and the movable terminals are unlocked, so that both terminals and both electrodes of the dry battery are pressed into contact with each other, so that electrical connection is possible.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a dry battery storage case,
A cylindrical case stepped hole 11 is provided on one side, and a cylindrical ring lock member 12 is fixed to the case stepped hole 11. The lock member 12 has a hole in the center thereof, a total of six triangular projections having high bases alternately in a crown shape at one end, and has a symmetrical inclined surface, and the other end forms a flat portion. .. On the other side of the dry battery storage case 1, a battery storage portion 13 that is a recess for storing the dry battery 7 is provided. A negative terminal 2 is guided by the hole of the lock member 12, is axially movable together with the lock member 12, and is electrically connected to the lead wire 5. Reference numeral 3 denotes a member to be locked, which has three triangular protrusions of the same height which engage with the protrusion inclined surface of the lock member 12 and are provided on the flange surface and have symmetrical inclined surfaces. Since the locked member 3 fixes the lead wire 5 through the hole, the locked member 3 is integrally movable together with the lead wire 5 and the negative terminal (movable terminal) 2. A compression spring 4 is provided between the side wall of the case stepped hole 11 and the locked member 3 in a stepped manner. A positive terminal (fixed terminal) 6 is fixed to the other side wall of the case 1 and is in contact with the positive electrode of the dry battery 7.

Next, the operation will be described. In FIG. 1, the inside of the minus terminal 2 side of the dry battery storage case 1 has the same operation as the knock mechanism of a knock type ball-point pen due to the locked member 3 and the spring 4, and the dry battery 7 slides once in the direction of the arrow. Then, the low protrusion of the locked member 3 is separated from the protrusion inclined surface of the lock member 12, and is rotated by a slight angle by the spring pressure, and again the high protrusion adjacent to the locked member 3 is protruded by the spring pressure. The inclined surface is pressed and engaged. The lock of the lock mechanism portion 3 is released, and as shown in FIG. 2, both electrodes of the dry battery 7 are pressed into contact with the negative terminal 2 and the positive terminal 6 and electrically connected. Here, the negative terminal 2 is connected to the body circuit by a lead wire 5.

When the dry battery 7 is slid once again from the state of FIG. 2 in the direction of the arrow, the negative terminal 2 is locked with the dry battery storage case 1 slightly inserted as shown in FIG. The dry battery 7 is in a free state, and can be taken out and stored easily and smoothly.
Finally, in the above description, an example in which the locked member 3 is configured on the minus terminal 2 side with one dry battery has been described, but even when a plurality of dry batteries 7 are arranged in series or in parallel,
Further, the application of forming the lock mechanism section 3 on the positive terminal 6 side is also sufficiently possible.

[0010]

As described above, according to the present invention, by configuring either the positive terminal or the negative terminal of the dry battery storage portion by the movable terminal having the lock mechanism,
When the dry battery is slid to the movable terminal side, the locked state and the unlocked state are alternately repeated, and the locked state has an effect that the dry battery can be taken out and stored easily and smoothly.
