Abstract

(57) [Abstract] [Purpose] To provide a battery holder that does not take up space and allows easy battery replacement operation. [Structure] When the battery B is pressed against the concave portion 2 from directly above the concave portion 2, the battery B hits the bulging portion 6c, and both side portions 6b, 6b of the positive terminal 6 are radially outwardly repulsed by the spring force. It is pushed out against and is stored in the recess 2. In this state, the negative pole of the battery B contacts the negative terminal 4 and the positive pole contacts the positive terminal 6. Further, the lower surface of the battery B does not come into contact with the bottom surface of the recessed portion, and is held on the protrusions 5 and 5, that is, about 1/3 of the left and right side portions is floated from the bottom surface of the recessed portion.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a disc-shaped (button-shaped) battery holder such as a lithium battery to be loaded in a video camera.

[0002]

[Prior art]

 As a holder for a disk-shaped battery such as a lithium battery, the one disclosed in Japanese Patent Publication No. 3-40464 is known. In this holder, a terminal plate made of an elastic plate is laid over the bottom of the ring-shaped holder body to form a battery storage part.The front part of the opening part of this storage part has a front flange part and a rear part has a rear flange part. When loading the battery into the holder, insert the battery diagonally between the front and rear flanges and push the terminal plate in as far as it will go, and then slightly return the battery to the front. When removing, the battery is pushed inward and the elastic force of the terminal board lifts the battery diagonally.

[0003]

[Problems to be solved by the device]

 In the conventional battery holder described above, it is troublesome to replace the battery because the battery needs to be slid and pulled from the side with respect to the holder, and a space is required for sliding the battery. This imposes restrictions on the arrangement of other members, and further complicates the shape such as the front and rear flanges.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the battery holder according to the present invention is provided with a substantially circular recess in the battery holder body for accommodating a disk-shaped battery, and the diameter of the recess can be increased or decreased in the radial direction at the periphery of the opening. An elastic member is provided to allow the battery to move in and out of the recess by expanding the diameter, and to urge the battery toward the bottom surface of the recess by reducing the diameter. A ridge is provided to hold it from above.

[0005]

[Action]

 When loading the battery, push the battery in the direction perpendicular to the recess of the holder, and when removing it, push one side of the battery.

【Example】

 Embodiments of the present invention will be described below with reference to the accompanying drawings. Here, FIG. 1 is a plan view of a battery holder according to the present invention, and FIGS. 2A to 2C are vertical cross-sectional views showing a state of loading and unloading a battery with respect to the battery holder. A disc-shaped lithium battery is shown as the battery. This lithium battery has electrodes on the outer peripheral surface and one end surface.

In the battery holder, a resin holder body 1 is provided with a recess 2 slightly larger than the lithium battery B, and a leaf spring 3 is inserted from the side along the bottom surface of the recess 2 so that the leaf spring 3 A part of the gimbal is cut out to form the minus terminal 4 located above the bottom surface.

Further, two ridges 5 and 5 are provided on the bottom surface of the recess 2 so as to sandwich the leaf spring 3 from the left and right. The base end portions 5a, 5a of these ridges 5, 5 spread outward so as to serve as a guide when the leaf spring 3 is assembled, and the tip end portions 5b, 5b are bent inward to position the leaf spring 3. There is.

On the other hand, a positive terminal 6 is provided on the periphery of the opening of the recess 2. The positive terminal 6 is composed of a leaf spring, the central portion 6a thereof is fixed to the opposite side to the insertion direction of the leaf spring 3, and both side portions 6b and 6b are arranged inside the peripheral edge of the opening of the recess 2. As shown in FIG. 2, the side portion 6b has a radially inwardly bulging portion 6c at the widthwise middle portion, and a guide portion 6d for pushing the battery B is provided on the side portion 6b. There is.

In the above, to load the battery B into the holder, the battery B is pressed into the recess 2 from directly above the recess 2, as shown in FIG. Then, the battery B hits the bulging portion 6c, and both side portions 6b, 6b of the positive terminal 6 are pushed outward in the radial direction against the elastic force of the spring, and the battery B is shown in FIG. 2 (b). It is stored in the recess 2 as shown. In this state, the negative pole of the battery B contacts the negative terminal 4 and the positive pole contacts the positive terminal 6. Further, the lower surface of the battery B does not come into contact with the bottom surface of the recess, but is held on the ridges 5 and 5, that is, about 1/3 of the left and right sides are held floating from the bottom surface of the recess.

On the other hand, when removing the battery B from the battery holder, as shown in FIG. 2C, one of the left and right sides of the battery B is pushed with a finger. Then, the battery B swings with the upper end portion of one of the protrusions 5 as a fulcrum, and the other side portion pushes the side portion 6b of the plus terminal 6 outward in the radial direction and comes out of the recess 2.

FIG. 3 is a longitudinal sectional view showing another embodiment. In the above embodiment, the plus terminal 6 also serves as an elastic member for holding the battery B, whereas in this embodiment, the plus terminal 6 is used. Separately from the holder body 1, the elastic piece 7 is integrally erected. The elastic piece 7 holds the battery B. Further, the holder body 1 does not have to be an independent part, and may be formed in one part of the exterior of the video camera.

In the illustrated example, the number of ridges is two, but it may be one, and the shape of the ridge is linear in plan view, but within a range that does not interfere with the leaf spring that serves as a terminal. It may have an arc shape.

[0014]

[Effect of device]

 As described above, the battery holder according to the present invention is provided with the elastic member at the peripheral edge of the opening of the recess for loading the battery, and when the battery is loaded, the elastic member spreads radially outward to form the recess. On the other hand, loading from the orthogonal direction is possible, and by providing a ridge on the bottom surface of the recess and pushing in one side of the battery, the battery becomes slanted in the recess with the ridge as a fulcrum and resists the elastic member. Since it can be detached, it can be easily attached and detached with one fingertip, and it is also advantageous in terms of space.

In particular, when the elastic member provided in the opening of the recess is also used as the terminal, the number of parts can be reduced and the cost can be effectively reduced.
