There was a problem in that the connector part could be damaged due to this action.

The present invention was developed to solve the above problems, and prevents the battery case from being inserted into the battery case storage recess in an inclined state, thereby preventing excessive force from being applied to the connector part. The purpose is to provide a battery case storage structure.

[Means for solving problems]

The battery case storage structure of the present invention includes a protruding guide rail formed on two side faces that are perpendicular to the open side and located opposite each other, and the two protrusions on the face opposite to the open side. a battery case storage recess provided with a connector portion provided near one of the shaped guide rails; groove portions provided on both side surfaces and slidably fitted into the two protruding guide rails; and the connector portion. and a protrusion provided on the bottom side of the battery case from one of the grooves on the side far from the battery case side connector part, so that the protrusion is properly connected to the battery case storage recess. It is configured to include a battery case that is slidably fitted with a clearance.

〔Example〕

Next, embodiments of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a perspective view showing one embodiment of the present invention;
The figure is a view taken along the arrows in FIG.

The battery case storage structure shown in FIG. 1 includes a battery case storage recess 2 formed on the back surface 1a of a portable computer terminal body 1, and a battery case 3 that slides into the battery case storage recess 2. configured.

A battery case accommodating recess 2 for accommodating a battery case 3 is formed on the back surface 1a of the computer terminal main body 1 with an appropriate clearance t. The battery case storage recess 2 has one side open, and two side surfaces 4 that are perpendicular to the one side and opposite each other.
Protruding guide rails 5a and 5b extending parallel to the bottom surface 6 are provided on a and 4b, respectively. As shown in FIG. 2, the two side surfaces 4a and 4b are both sloped so that the bottom surface 6 side of the battery case storage recess 2 is narrower. A connector portion 7 that enables electrical connection with the battery case 3 is formed protrudingly on the surface facing the open side portion on the side closer to the one protruding guide rail 5a. .

On the other hand, on both sides 8a and 8b of the battery case 3,
Grooves 9a and 9b are formed in the protruding guide rails 5a and 5b, respectively, into which they can be slidably fitted. Further, on the end surface 11 of the battery case 3 on the front side when inserted into the battery case storage recess 2, a built-in connector 10 is provided as a case-side connector part that fits into the connector part 7 on the battery case storage recess 2 side.

Side surface 8b on the bottom surface 6 side and end surface 11 side from the one groove portion 9b on the side far from this built-in connector 10
is provided with a protrusion 12 whose height is approximately the same as or slightly lower than the clearance t described above. In the above configuration, when the battery case 3 is slid into the battery case storage recess 2 from the end surface 11 side by fitting the grooves 9a, 9b and the protruding guide rails 5a, 5b, the connector on the battery case storage recess 2 side The part 7 and the built-in connector 10 on the battery case 3 side are fitted into each other, and the two are electrically connected, making it possible to supply power to the computer terminal main body 1.

When the battery case 3 is inserted into the battery case housing recess 2, as shown in FIG. If the battery case storage recess 2 is not pushed in and pushed in at an angle, the protrusion 12 will hit the end of the protruding guide rail 5b at the beginning of the push-in, making it impossible to push it in any further. This prevents the built-in connector 10 of the battery case 3 from being connected to the connector portion 7 of the battery case storage recess 2 in an inclined state. As a result, the action of excessive force on each connector portion can be avoided, and damage to each connector portion can also be prevented.

Note that, contrary to the above, if the battery case 3 is pushed into the battery case storage recess 2 without the protruding guide rail 5a on the side closer to the connector part 7 and built-in connector 10 and the groove part 9a fitting together, Since there is no protrusion on the side surface 8a to prevent incorrect insertion, it is possible to push the battery case 3 all the way in. However, in this case, the built-in connector 10 side of the battery case 3 is not connected to the bottom surface 6 of the battery case storage recess 2. connector part 7.
Therefore, in this case, no excessive force will be applied to the connector portion 7 and the built-in connector 10, and no damage will occur.

[Effect of the invention] When the battery case storage structure of the invention is incorrectly inserted into the battery case storage recess, the protrusion that comes into contact with the end of the protruding guide rail provided on the side of the battery case storage recess is inserted into the battery case. This prevents the battery case from being stored in an inclined position with respect to the battery case storage recess, and prevents undue force on the connector part due to the two connector parts being connected to each other in an inclined position. This has the advantage of being able to avoid the effects of this and prevent damage to the connector section.
