Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention accommodates a battery in a holder, mounts the holder on a mounting portion of a device body, and uses contacts arranged in the mounting portion as electrodes of the battery. The present invention relates to a battery holding device that is brought into contact with each other to drive a device.

[Outline of device]

The present invention is, for example, in a button type battery holding device of a card type radio receiver, in which a bent portion is formed on each side of a contact point of a spring having both functions of crimping and taking out from the positive electrode of the battery. It is designed to obtain a strong spring pressure in a small space by the two bent portions.

[Conventional technology]

Generally, in a portable electronic device, for example, a card type radio receiver, a battery is used as its power source so that the radio receiver can receive a broadcast anywhere. In such a receiver, for example, a button type lithium battery is used, and such a battery is inserted into the holder, the holder is mounted at the mounting position of the cabinet, and the contacts are connected to the positive side of the battery and The electrodes on the minus side are brought into contact with each other for electrical connection. Therefore, the battery is connected to the predetermined circuit of the radio receiver via the contact, and thereby the radio receiver is driven.

[Problems to be solved by the invention]

The terminal mounted in the mounting position can obtain a stable connection so as to generate a high contact pressure with the electrode of the battery. Further, by urging the holder holding the battery in the removing direction, the battery removing operation becomes easy. Therefore, by providing the contact point on the conductive spring,
You will be able to share both. When such a spring is composed of a leaf spring and a large elastic restoring force is obtained, its cross-sectional area may be increased. However, when used in a thin set such as a card type radio receiver, the width of the spring is limited, and the plate thickness of the spring cannot be so large. By increasing the flexure of the leaf spring, the elastic restoring force also increases, but in this case, the amount of flexure is limited considering the settling of the leaf spring.

The present invention has been made in view of the above problems, and a battery holding device having a spring having a strong elastic restoring force without increasing the size and having a strong spring force. It is intended to provide.

[Means for solving problems]

The present invention relates to a device in which a battery is housed in a holder, the holder is mounted on a mounting portion of a device body, and contacts arranged in the mounting portion are brought into contact with electrodes of the battery. A conductive spring, which also serves as a contact for contacting one of the electrodes and a biasing means for taking out the holder, is provided, and the conductive spring has a mounting portion on the base end side thereof, and the mounting portion and the contact point. And a second bent portion is formed between the contact and the free end on the tip side, and a notch is provided on the tip side in the insertion direction of the battery case. The contact is formed in a V shape so as to fit into the notch, and when the battery holder accommodating and holding the battery is mounted on the mounting portion, the contact of the conductive spring is passed through the notch of the battery holder to the battery. One side When the first bent portion is elastically deformed and the first bent portion is deformed by a predetermined amount while being in contact with the electrode, the free end of the spring comes into contact with a predetermined position of the mounting portion, The present invention relates to a battery holding device, wherein the second bent portion is elastically deformed together with the bent portion.

[Action]

Therefore, when the battery is housed and held in the battery holder and the battery holder is mounted on the mounting portion, the contact point of the conductive spring enters the holder through the notch of the battery holder and contacts one electrode of the battery. When the battery holder is further inserted, the first bent portion on the mounting portion side is elastically deformed, and when the first bent portion is deformed by a predetermined amount, the free end side of this spring comes into contact with the predetermined position of the mounting portion. As a result, the second bent portion is elastically deformed together with the first bent portion. By utilizing the elastic restoring force that accompanies the elastic deformation of the two bent portions, it is possible to urge the battery holder when the battery holder is taken out.

〔Example〕

FIG. 3 shows a battery holding device of a card type radio receiver according to an embodiment of the present invention, in which a mounting portion 11 formed of a recess is provided on a side portion of a cabinet 10 of the card type radio receiver. The battery 12 is mounted on the mounting portion 11. Battery 12
Is held by the circular holding portion 14 of the battery holder 13. In this state, the holder 13 is inserted into the mounting portion 11 for mounting.

The structure of the mounting part 11 will be described. As shown in FIGS. 1 and 2, the mounting part 11 is composed of a space surrounded by ribs 18, and a part of the mounting part 11 is provided inside the cabinet 10. Is provided with a circuit board 19. Electronic components are mounted on the substrate 19 to form a predetermined circuit of the radio receiver. A spring 20 made of a conductive metal is attached to the circuit board 19. The spring 20 is attached to the circuit board 19 by an attachment portion 21 on the base end side thereof, and is electrically connected. A contact point 22 is formed on the tip side of the spring 20 so as to come into contact with the outer peripheral surface of the battery 12 through the notch 23 of the holder 13. And the contact 2 of this spring 20
Bent portions 24 and 25 are respectively formed on both sides of 2, and the elastic restoring force is generated by the deformation of these bent portions 24 and 25. A contact 27 is formed in the recess 11 to contact an electrode on the opposite side of the lower surface of the battery 12.

A lock lever 30 is further arranged in the cabinet 10. The lock lever 30 is the rib 1 of the mounting portion 11.
8 is provided so as to face the lacking portion, is rotatably supported by a pin 31, and is urged clockwise by the elastic piece 32 about the pin 31 in FIGS. 1 and 2. There is. Thereby, the claw 33 is engaged with the engaging recess 34 of the holder 13 holding the battery 12. Also, the button 3 of the lock lever 30
5 is an opening 36 formed in the side surface of the cabinet 10.
It is designed to stick out.

In the above structure, the button-type battery 12 is housed in the circular holding portion 14 of the holder 13 as shown in FIG. 1, and the holder 13 is moved upward in FIG. To be attached to. Then, the battery 12 held in the holder 13 has a notch 23
Through the contact 22 of the leaf spring 20. When the holder 13 is further pushed in, the first bent portion 24 of the leaf spring 20 is first deformed, and then the second bent portion 25 contacts the rib 18 and is deformed as shown in FIG. The engaging recess 34 of the holder 13 is engaged with the claw 33 of the lock lever 30, so that the battery holder 13 is locked at the mounting position as shown in FIG.

In this state, the positive electrode of the battery 12 is connected to the predetermined wiring pattern of the circuit board 19 via the contact 22 and the spring 20. Holder 1 at the same time
The other electrode on the lower surface of the battery 12 held in No. 3 is brought into contact with the other contact 27 formed on the lower surface of the mounting portion 11, thereby driving the receiving circuit of the radio receiver. Will be done. Further, at this time, as described above, since the two bent portions 24 and 25 of the spring 20 are both deformed, the holder 13 is biased in the take-out direction by the elastic restoring force thereof, and this biasing force is applied to the lock lever 30. Will be received by.

Next, when the button 35 of the lock lever 30 is pressed from the outside, the lock lever 30 is rotated counterclockwise in FIG. 2 against the elastic piece 32. Therefore, the lock of the holder 13 is released, and the holder 13 is pushed in the push-out direction by the elastic restoring force of the two bent portions 24, 25 of the spring 20, which causes the state shown in FIG. The state is changed to that shown in FIG. This operation is achieved by the spring 20 pushing the holder 13 via the battery 12, but when the holder 13 is pushed in without the battery 12, the button 35 of the lock lever 30 is pushed. The portions of the spring 20 on both sides of the contact 22 push the edges of the notch 23 of the holder 13 on both sides, thereby pushing the holder 13 out.

According to such a holding device for the battery 12, since the spring 20 that generates the biasing force generates the biasing force by the elastic restoring force caused by the deformation of the pair of bent portions 24 and 25, the two plates apparently appear. This is the same as the action of the spring, and the resultant force of the elastic restoring forces of the two bent portions 24 and 25 becomes the elastic restoring force of the leaf spring 20. Therefore, it becomes possible to take out a strong force even with a small amount of bending, whereby the contact 22 can be brought into contact with the positive side contact of the battery 12 by a strong crimping force, or the holder 13 can be reliably pushed out.
