Description

[Detailed Description of the Invention] The present invention relates to a dry battery holder, and an object of the present invention is to provide a dry battery holder that can prevent the dry battery from falling off by providing a stopper at a predetermined position near the negative electrode storage section of the dry battery.

FIG. 1 shows a longitudinal sectional view of an example of a conventional dry battery holder. In the figure, 1 is a dry battery holder, which consists of a housing 2 and a positive electrode plate 3 and a negative electrode plate 4 provided in the housing 2, with the positive electrode of the dry battery 5 being connected to the positive electrode plate 3,
Further, a negative electrode is housed in contact with the negative electrode plate 4. The conventional dry battery holder 1 described above holds the dry battery 5 by the pressing force of the negative electrode plate 4 in the direction of the positive electrode plate 3, and a protrusion 3a is provided on the upper part of the positive electrode plate 3 to hold the dry battery 5 between the positive and negative electrodes. Prevents it from coming off the electrode.

However, since the conventional dry battery holder 1 described above presses the dry battery 5 in the direction of the positive electrode plate 3 only by the spring force of the negative electrode plate 4, the dry battery 5 is pushed away from the battery holder 1 even in the event of a relatively mild shock or vibration. It had the disadvantage that it could come off.

The present invention eliminates the above-mentioned drawbacks, and the embodiments thereof will be described below with reference to the drawings.

FIG. 2 shows a perspective view of a first embodiment of the dry battery holder according to the present invention. In the figure, the dry battery holder 6 is
A positive electrode plate 7 and a negative electrode plate 8 are fixed to opposing walls in the housing, a protrusion 9 is provided on the upper part of the positive electrode plate 7, and a dry battery is provided on the upper part of the housing near the negative electrode plate 8 to be stored. A stopper 10 having a locking portion extending in a direction perpendicular to the longitudinal direction is integrally molded. Like the conventional negative electrode plate 4, the negative electrode plate 8 has an elastic structure to apply a pressing force in the direction of the positive electrode plate 7, and the protrusion 9 prevents reverse connection of the dry cell and prevents the battery from being connected to the positive electrode. It also works to prevent it from coming off.

When storing a dry battery in the battery holder 6, as shown in FIG. 3, first the negative electrode of the dry battery 11 is brought into contact with the negative electrode plate 8, and at the same time, the lower end of the negative electrode side of the dry battery 11 is brought into contact with the housing. Then, while applying force in the X direction in FIG. 3 and pushing the negative electrode 8 to the right in the figure against the spring force of the negative electrode 8, the positive electrode of the dry battery 11 is moved to the protrusion. Press 9 down. As a result, the dry battery 11 is placed in the battery holder 6.
The positive electrode of the dry battery 11 is pressed against the positive electrode plate 7, and the negative electrode is pressed against the negative electrode plate 8 by the spring force of the negative electrode plate 8. Ru. The protrusion 9 may be made of an elastic member that is deformed by pressure with the positive electrode of the dry battery 11 and returns to its original state after the pressure is released.

Figures 4A, B and C are respectively the first and second figures shown in the second figure above.
A front view, a top view, and a vertical side view are shown when a dry battery 11 is housed in the dry battery holder 6 of the example. The protrusion length a of the protrusion 9 in the direction of the negative electrode 8 shown in FIG. Also, the distance b between the stopper 10 and the inner wall surface of the housing to which the negative electrode plate 8 is fixed as shown in FIG. 4B.
and the distance c between the lower end surface of the stopper 10 on the dry battery side and the lower surface of the housing of the dry battery holder 6 are set to predetermined dimensions so as not to interfere with insertion or removal of the dry battery 11, respectively. Note that in order to prevent the dry battery 11 from coming off even if the impact force is as large as possible while remaining in contact with the positive electrode plate 7 and the negative electrode plate 8, the stopper shown in FIG. 4B is used. It is desirable to make the distance g between the lower end surface of the battery 10 and the upper end side surface of the dry battery 11 as small as possible.

Further, as shown in FIG. 4C, the length d of the stopper 10 of the portion of the dry cell holder 6 extending in the direction inside the case and the distance c are the diameter e of the dry cell 11 and the distance between the end face of the stopper 10 and the case. When the length of the opening between the upper part of the body and the upper part of the body is f, each design is made so that e>f.

The dry battery 11 housed and held in the dry battery holder 6 having the above configuration and dimensions is subjected to a force greater than the pressing force exerted by the negative electrode plate 8 upward in FIG. 4B due to vibrations, shocks, etc. Also, since the positive electrode of the dry battery 11 is locked by the protrusion 9 and the part of the dry battery 11 near the negative electrode is locked by the stopper 10, they are prevented from coming off from the dry battery holder 6. According to this embodiment, it has been experimentally confirmed that the dry battery 11 does not come off even under a force that is about five times the force that would cause the dry battery 5 to come off in the conventional dry battery holder 1.

Note that, when the dry battery 11 is to be removed from the dry battery holder 6, this can be easily done by pulling out the positive electrode side portion of the dry battery 11 in the Y direction, as shown in FIG.

Next, a second embodiment of the dry battery holder according to the present invention will be described with reference to FIGS. 5 and 6. In both figures, the same components as in FIG. 2 are designated by the same numbers.
The explanation will be omitted. Dry battery holder 1 of this embodiment
No. 2 is a device in which the upper part of the casing near the negative electrode 8 is covered with a stopper 13 extending in a direction orthogonal to the longitudinal direction of the dry battery 11 by integral molding. According to this embodiment, since the negative electrode portion of the dry battery 11 is completely prevented from coming off, it is possible to prevent the dry battery from coming off even under stronger force than in the first embodiment.

As described above, the dry battery holder of the present invention includes a protrusion that protrudes in the longitudinal direction of the dry cell at a position above the positive electrode of the stored dry cell to prevent the dry cell from falling off;
A stopper that extends in a direction perpendicular to the longitudinal direction of the battery at a position above the area near the negative electrode of the dry battery and restricts movement of the area near the negative electrode of the dry battery is integrally molded with the housing, so that Compared to conventional dry battery holders, which prevent batteries from falling out by the pressing force of the electrode plate and the protrusion above the positive electrode of the dry cell, the battery can be prevented from falling off even when an impact force of about five times is applied. Moreover, since the stopper is provided by integral molding, the manufacturing process can be simplified, and the dry battery can be easily attached and detached.
