[Means for Solving the Problems]

 The battery case according to claim 1 is a case in which a battery is inserted into an opening in which a positive electrode terminal and a spring-shaped negative electrode terminal are provided on opposed inner surfaces. A plurality of ribs for supporting the battery are formed on the bottom surface of the opening so as to intersect with the direction connecting the negative electrode terminal and the positive electrode terminal. The plurality of ribs are used to insert the battery into the opening. In such a case, the battery is provided at a position where the insertion of the battery is not hindered in a state where the negative electrode terminal and the end of the battery are in contact with each other, and the height is set.

[0008] The battery case is attached to or incorporated in an electric product, and supplies electricity from a battery provided therein. The depth of the opening of the battery case is deeper than the diameter of the battery. For this reason, a plurality of ribs for supporting the battery are provided on the bottom surface of the opening of the battery case so as to extend in a direction intersecting the direction connecting the negative electrode terminal and the positive electrode terminal. The battery inserted into the battery case is supported by the ribs, and the height of the electrode of the inserted battery and the height of the negative electrode and the positive electrode terminal of the battery case are aligned. In addition, the provision of the ribs improves the rigidity of the battery case.

When the battery is inserted into the battery case, the battery is inserted so that the battery slides along the bottom surface of the battery case while pressing the end of the battery against the spring-like negative terminal of the battery case. After the negative terminal shrinks until the battery can be set in the opening, set the other end of the battery to the positive terminal.

[0010] At this time, a rib for supporting the battery and aligning the terminals is provided on the bottom surface of the opening, but this rib prevents the battery from being inserted when the battery is inserted. It is installed at a position where it does not interfere with the battery and is set at a height that does not interfere with the battery, so that the battery can be inserted smoothly.

A battery case according to a second aspect includes a box, a negative electrode terminal, a positive electrode terminal, and a plurality of ribs. The box has an opening through which a battery for power supply is inserted. The negative electrode terminal has a spring shape, is provided on the inner surface of the opening, and comes into contact with the negative electrode of the battery when the battery is inserted into the opening. The positive electrode terminal is provided on the inner surface of the opening facing the negative electrode terminal, and comes into contact with the positive electrode of the battery when the battery is inserted into the opening. The plurality of ribs are opened so as to intersect the direction connecting the negative electrode terminal and the positive electrode terminal at a position where the battery terminal is not obstructed when the negative electrode terminal and the negative electrode of the battery contact each other when the battery is inserted into the box portion. It is provided on the bottom of the part.

When the battery is inserted into the battery case, the battery is inserted so as to slide along the bottom surface of the case while pressing the end of the battery against the spring-like negative terminal of the battery case, and the entire battery is opened. After the negative terminal has shrunk until it can be set in the battery compartment, set the other end of the battery to the positive terminal.

[0013] Here, a rib is provided on the bottom surface of the opening, but this rib is provided at a position that does not hinder the loading when the battery is loaded, so that the battery can be loaded smoothly. Can be.

A battery case according to a third aspect is the battery case according to the second aspect, wherein the plurality of ribs are provided on a bottom surface of an opening near an intermediate position between the negative electrode terminal and the positive electrode terminal. .

Here, the rib is provided near the middle position of the bottom surface, that is, apart from the negative electrode terminal. As a result, when the battery is inserted into the battery case, the ribs do not hinder the battery from sliding with respect to the bottom surface.

A battery case according to a fourth aspect is the battery case according to the second or third aspect, wherein the plurality of ribs do not hinder the insertion of the battery when the battery is inserted into the box portion. In addition, a rib having a height at which the battery does not contact is provided at a position where the battery does not contact.

Here, the rib is provided at a position where the battery does not come into contact with the rib when the battery is inserted into the battery case. Thus, the battery can be easily inserted into the battery case.

A battery case according to a fifth aspect is the battery case according to the second to fourth aspects, wherein the number of ribs is two. If there is only one rib, the battery supported by the rib is not stable, so that it is necessary to adjust at the time of loading in order to surely contact the negative electrode and the positive electrode terminal.

Here, since two ribs are formed, by appropriately setting the heights of the ribs, the battery can be stably and appropriately contacted with the negative electrode and the positive electrode terminal. A battery case according to claim 6 is the battery case according to any one of claims 2 to 5, wherein the box portion is a remote control main body for remote operation.

Here, since the battery case is used in the remote control main body, the battery insertion of the remote control can be performed smoothly.

[0021]

[Embodiment of the invention]

 The remote control 1 shown in FIG. 1 has the battery case 2 of the present invention. The remote control 1 is a remote control for operating a video (not shown). FIG. 1 shows the front surface of the remote controller 1 and FIG. FIG. 3 is a cross-sectional view of the remote controller 1 taken along the plane AA in FIG.

<Overall Configuration> The remote control 1 has a plurality of operation buttons 10 on its surface. The operation button 10 is a button for performing operations such as power supply, channel, playback, and stop of a video (not shown).

On the other hand, the remote control 1 includes a battery case 2 below the back surface. The battery case 2 has a lid 20, an opening 21, two positive terminals 22, two negative terminals 23, and two ribs 24.

The lid 20 is a member for closing the opening 21 of the battery case 2 and preventing the battery C inserted in the battery case 2 from dropping off. The opening 21 is a space in which the substantially rectangular parallelepiped battery C is inserted, and is closed by the lid 20. The depth of the opening 21 in the height direction is larger than the diameter of the battery C.

The positive electrode terminal 22 is a terminal for making contact with the positive electrode of the battery C inserted into the opening 21, and is provided on the inner surface of the opening 21. The negative electrode terminal 23 is a terminal for contacting the negative electrode of the battery C inserted in the opening 21, and is provided on the inner surface of the opening 21 facing the positive electrode terminal 22. Also, since the shape of the negative electrode terminal 23 is spring-shaped, the battery C is pressed against the positive electrode terminal 22 by the negative electrode terminal 23, and the battery C is held by the opening 21. As shown in FIG. 2, the two positive electrode terminals 22 and the two negative electrode terminals 23 are provided at diagonal positions on the inner surface of the opening 21.

Two ribs 24 are provided on the bottom surface of the opening 21 in the vicinity of an intermediate position between the positive terminal 22 and the negative terminal 23 so as to extend in a direction intersecting the direction connecting the terminals 22 and 23. (See FIG. 3A). Here, the battery case section 2 is not provided with a board (not shown) built in the remote controller 1. Therefore, when the rib 24 is not provided, the battery C is directly supported on the bottom surface of the opening 21. However, since the bottom surface of the opening 21 is generally formed on a curved surface, if the battery C is directly disposed on the bottom surface of the opening 21, the positive terminal 22 and the negative terminal 23 are not connected when the battery C is inserted. The battery poles do not contact properly. Therefore, in the present embodiment, two ribs 24 are provided on the bottom surface of the opening 21 to support the battery C in a stable posture by the ribs 24, and when the battery C is inserted into the opening 21, The height position of the battery C is adjusted so that the positive electrode and the negative electrode of the battery C and the positive electrode terminal 22 and the negative electrode terminal 23 are securely in contact with each other. Further, the rib 24 also plays a role as a reinforcing member for maintaining the strength while reducing the weight of the remote controller 1.

<Operation> By inserting two batteries C into the battery case 2, a video operation can be performed by pressing the operation button 10 of the remote controller 1. When the life of the battery C has expired, it can be further used by replacing it with a new battery C.

FIG. 3B is a diagram when the battery C is started to be inserted into the battery case 2 by removing the lid 20. When the battery C is to be inserted into the battery case portion 2, the charging is started by contacting the bottom and side surfaces of the opening 21 and the negative electrode terminal 23, and the negative electrode is kept until the entire battery C can be set in the opening 21. The positive electrode of the battery C is set in the positive electrode terminal 22 by compressing the terminal 23 and inserted into the opening 21.

As shown in FIG. 3B, two ribs 24 are provided near the middle between the positive terminal 22 and the negative terminal 23 so as not to come into contact with the battery at the start of charging. Further, when the battery C compresses the negative electrode terminal 23, the rib 24 is provided at a position where the rib 24 does not interfere with the position at which the bottom surface of the opening 21 contacts the battery C. For this reason, the rib 24 does not prevent the battery C from being inserted into the opening 21. For this reason, the battery C is easily inserted into the battery case 2.

<Other Examples> The remote controller 1 described in the above embodiment is a remote controller for video operation. However, a remote control having a built-in battery, such as a television, a DVD player, and an air conditioner, may be used.

The battery case according to the present invention is not limited to a remote controller, and may be used for a small electric device using a battery.
