[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery storage unit, and more particularly to a battery storage unit used for a portable telephone.

[0002]

2. Description of the Related Art In a portable telephone, a unit such as a non-rechargeable dry battery may be temporarily used in addition to a rechargeable battery unit such as a Ni-Cd battery.
When this battery unit is worn out, the internal battery must be replaced without fail. For this reason, various dry cell storage units with lids have been proposed.

[0003]

However, in the conventional dry cell storage unit, when the lid of the battery unit is removed to replace the dry cell, the repulsive force of the coil spring or the leaf spring used to secure the dry cell contact. There was a risk that the lid would pop out at high speed and be lost. In the case of fixing the lid using screws, it is possible to prevent the lid from popping out when the lid is removed, but the work to rotate the screws is involved, and the removal operation of the lid is not easy . As described above, many parts are required to prevent the cover from being released or lost, and the work for assembling is also complicated.

An object of the present invention is to provide a dry cell storage unit which eliminates the above-mentioned disadvantages of the prior art, minimizes the number of parts, and simplifies the operation of manufacturing and assembling a dry cell unit or attaching / detaching a lid when replacing a battery. To provide.

[0005]

The dry battery storage unit of the present invention comprises a battery storage case and a battery cover for closing an opening end surface of the battery storage case, and the battery cover is inserted into the battery storage case. The battery case has a key-shaped protrusion formed at a tip thereof, and the battery storage case has the key-shaped protrusions at a position where the two protrusions are completely inserted into the battery storage case and a position where the protrusion is pulled out halfway, respectively. Having a first and second stepped portion that engages with the portion, and a handle portion that is deformed to press the key-shaped portion at a position where the two protrusions are completely inserted, and pressing the handle portion. Thus, the key-shaped portion can be detached from the first step portion.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

FIGS. 1 to 3 show a dry battery storage unit according to the present invention, wherein 1 is a battery storage case, 2 is a dry battery, 3 is a battery cover, and 4 is a battery holder attached to the battery storage case 1 and the battery cover 3, respectively. Negative terminal portions 5 and 5 are coil springs attached to the negative terminal portions.

In the present invention, two projections 7 are provided on both sides of the end face of the battery lid 3 in contact with the open end face 6 of the battery storage case 1.
7 are projected from each other, and a key-like portion 8 is formed on the outer surface of the leading end of each of the two shape projections 7, 7, and the two shape projections 7, 7 are completely inserted into the battery housing case 1. Key-like part 8
The first step 9 engaging with the key surface of the battery storage case 1
Are provided at corresponding portions of the inner wall surface, and the inner surface of the two projections 7 is an inclined surface. As a result, the thickness of the one projection 7 becomes smaller toward its tip.

In the present invention, the first step 9
And between the opening end face 6 of the battery storage case 1 and
A recess or groove 11 having a second step portion 10 engageable with the key surface of the key portion 8 is formed on the inner wall surface of the battery housing case 1 facing the outer surface of the two protrusions 7.

Further, in the present invention, in a state in which the two protrusions 7 are completely inserted into the battery storage case 1, a U-shaped portion is formed on a wall portion of the battery storage case 1 facing the key portion 8 of the one protrusion 7. A groove 12 is formed, and a handle portion 13 which can be pressed is formed in a wall portion surrounded by the groove 12, and a stopper 14 for preventing excessive deformation due to the pressing of the handle portion 13 is provided in the battery storage case. 1 is provided.

Since the dry battery storage unit of the present invention has the above-described configuration, a battery before use is put in the battery storage case 1 and the protrusion 7 of the battery cover 3 is pushed into the battery storage case 1. The key portion 8 advances to the first step portion 9 and is hooked, and the battery cover 3 is fixed at a predetermined position. This is the use state.

Next, when the battery is exhausted and replaced, a pair of handle portions 13 provided on the side surface of the battery housing case 1 are provided.
The key-shaped part 8 is disengaged from the first step part 9 by pushing the finger from both right and left sides, and the battery cover 3 is attached to the battery storage case 1 by the repulsive force of the coil spring 5 which secures the connection of the battery.
The key-shaped portion 8 gets caught on the second step portion 10 more,
As shown in FIG. 4, it is fixed again in a state where it has come out partway. In order to completely pull out the battery cover 3, the key-shaped portion 8 is pushed inward with a fingertip while holding the battery cover 3 that has been pulled out halfway. With the above operation, the battery cover 3 is pulled out while being completely held in the hand, so that the risk of being released or lost is greatly improved. Also, if the battery storage case and the battery lid are made of plastic, the necessary projections, steps and the like can be integrally formed, so that it is not necessary to prepare special components. This eliminates the need for a ribbon or string for preventing radiation, and eliminates the step of connecting them, which can contribute to a reduction in manufacturing cost.

FIG. 5, FIG. 6, and FIG. 7 show another embodiment of the dry battery storage unit of the present invention. In this embodiment, the tip of one projection 7 is bent into an L-shape, and the bent lower end is formed. The key portion 8 is provided, and the key portion 8 is formed into a cylindrical shape. It should be noted that the first,
The second steps 9, 10 are preferably each arcuate.

In this embodiment, the battery cover 3 is pulled out of the battery storage case 1 halfway, and the battery cover 3 is lowered with respect to the battery storage case 1 with the cylindrical key portion 8 abutting against the second step portion 10. In this state, the end face of the dry battery 2 is completely exposed, so that the dry battery can be replaced without removing the battery cover 3 from the battery storage case 1. it can.

[0015]

According to the dry cell storage unit of the present invention, the following effects can be obtained.

[0016] To use the snap fit, the battery cover can be set only by pushing in, turning the screw,
Operation is simplified because a screwdriver or the like is unnecessary.

The battery cover is prevented from being released or lost due to the repulsive force of the spring. Also, there is no need to add components for that.

The above effects can be obtained without increasing the manufacturing cost.
