This increases the manufacturing cost.
Japanese Patent Laid-Open No. 11-233083

  In view of the above, an object of the present invention is to provide a dry battery case in which the manufacturing cost can be reduced by sharing the case body even if the design of the cover plate is different.

In order to solve the above-mentioned problems, the present invention is a dry battery case that is accommodated in a body of a device that uses a dry battery, and is freely retracted forward through an entrance opened in a front panel of the body, and accepts the dry battery. In the case having a case main body and a lid plate that is located in front of the case main body and fits into the doorway when the battery case is stored in the container, a plurality of types of lid plates are prepared, Ri freely der cover plate replacement, the male coupling part to be inserted into respective female coupling part and the female coupling portion is protruded to the one and the other of the back of the front face of the case body and the cover plate, The male connecting portion includes a claw piece having a claw portion at a tip that engages with an engaging portion formed on the female connecting portion to prevent the male connecting portion from coming off from the female connecting portion, and on both sides of the claw piece. Turkey provided a pair of guide pieces sliding contact with the female connector portion The features.
In the present invention, the female connecting portion is formed in a rectangular tube shape having an internal space having a rectangular cross section, and the direction along the long side of the cross section of the female connecting portion is defined as the X-axis direction and the direction along the short side. In the Y-axis direction, the claw piece of the male connecting portion is located in the middle of the X-axis direction, and the pair of guide pieces of the male connecting portion are located on both sides in the X-axis direction and are located in the female connecting portion. The X-axis direction one end and the other end surface of each and the both side surfaces facing in the Y-axis direction are slidably contacted.

  According to the present invention, by attaching various lid plates to the case body, it is possible to manufacture a plurality of types of dry battery cases having different lid plate designs. And the case main body becomes a common part, and the reduction of manufacturing cost can be aimed at.

They are spaced apart. Further, the lid plate 6B is formed so that most of the lid plate 6B is accommodated in a lower region inclined obliquely rearward and downward of the front panel 11, so that the lid plate 6B is not conspicuous when viewed from above.

  The dry battery case 4 is accommodated in the container 1 so that it can be pulled out to the front of the front panel 11 through an entrance 14 opened at a predetermined location of the front panel 11. As shown in FIG. 3, the dry battery case 4 includes a resin case main body 5 that receives a dry battery (not shown), and is positioned in front of the case main body 5 when the dry battery case 4 is stored in the container 1. And a resin lid plate that fits into the doorway 14. Although not shown in the drawings, terminals in contact with the negative and positive electrodes of the dry battery are attached to the rear end portion and the front end portion of the case body 5.

  Here, in this embodiment, a lid plate 6A for the model shown in FIG. 1 and a lid plate 6B for the model shown in FIG. 2 are prepared as the lid plates, and these lid plates 6A and 6B can be freely replaced on the case body 5. It is said. According to this, by attaching various cover plates 6A and 6B to the case body 5, a plurality of types of dry battery cases 4 having different cover plate designs can be manufactured. Accordingly, it is possible to share one type of case main body 5 among a plurality of types of dry battery cases 4, thereby reducing the manufacturing cost.

  The case body 5 is formed with a stopper portion (not shown) for locking the battery case 4 at a predetermined storage position in the container 1 and a lever portion 51 for operating the stopper portion. Is integrally formed so as to extend forward of the case body 5. Each cover plate 6A, 6B has a hole 61 through which the lever portion 51 is inserted. Then, the lid plates 6A and 6B are pulled forward while the lever portion 51 is pushed up with a finger, so that the dry battery case 4 is pulled out to the front of the container 1.

  By the way, it is also conceivable to connect the cover plates 6A and 6B to the front end of the case body 5 with screws in order to make it possible to replace the cover plates 6A and 6B with the case body 5. However, this requires a screwing operation and takes time to assemble the dry battery case 4. Therefore, in the present embodiment, a rectangular tube-shaped female connecting portion 7 having an internal space having a rectangular cross section is provided on the front end surface of the case body 5 and a male connecting portion is provided on the back surface of each cover plate 6A, 6B. 8 so that the cover plates 6A and 6B can be easily connected to the case body 5 simply by inserting the male connection portion 8 into the female connection portion 7.

  Hereinafter, the direction along the long side of the cross-sectional shape of the female connection part 7 is defined as the X-axis direction, and the direction along the short side is defined as the Y-axis direction, and the female connection part 7 and the male connection part 8 are also referred to with reference to FIG. Detailed description. In this embodiment, the female connecting portion 7 is formed so that the X-axis direction is the up-down direction and the Y-axis direction is the left-right direction, but the X-axis direction is the left-right direction and the Y-axis direction is the up-down direction. It is also possible to form the female connecting part 7 as described above.

  A female connecting portion 7 is provided on the front end surface of the case body 5 so as to be spaced apart in the Y-axis direction, and the male connecting portion 8 is also provided on the back surface of each cover plate 6 so as to be spaced apart in the Y-axis direction.
