Abstract

PURPOSE:To facilitate loading and unloading of battery and realize more reliable connection of battery power supply by providing a contact segment having the contact area at the inner side than the end portion of upper wall which engagingly stops the end of battery to the bottom wall. CONSTITUTION:A flat battery B is inserted into a battery case 11 in such a way as being stabbed therein and it is then gradually pushed as it is fallen along a recessed portion 11a while it is being engaged with the upper wall member 13. Thereby the side edge of battery B collides with a rising portion 11b of the case 11. A contact segment 12 can be given previously an intensive spring force. When a battery is loaded, said contact segment is opposed to the battery, maintaining a high contact pressure between the battery and contact segment. Moreover, when the battery is inserted, the contact area of contact segment 12 slides with battery, resulting in the self-cleaning effect. Meanwhile, when a battery case 15 is removed for taking out the battery, the battery B is floated by a spring force of contact segment 12 and can easily be removed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a flat battery chamber used in cameras, etc., in which a coin-shaped flat battery such as Lychicum Kameike is installed as a battery power source. The present invention relates to the structure of a flat battery compartment.

[Conventional technology]

A flat battery with ten electrodes on the front and back (including the side edges) is thin, so it is used as a power source for a microcomputer in a camera, etc., and a battery compartment is provided in the small space of the camera. It is possible to use it by wearing it. Figure 3 shows a conventional flat battery compartment, and Figure 3 (a) shows the #tt battery source taken out from the surface and side edges of the flat battery B.
The battery case 31 is provided with a T contact piece 32 that contacts near the center of the surface of the flat battery B, and a contact piece mark 234 that contacts the side edge of the flat 1L battery B. Although it is a battery cover, it is a flat battery B battery case 3.
1, an electrical connection is immediately made. In this conventional arrangement, the contacts 8 and 11 of the contact pieces 0 and 34 are not in opposing positions, so there is a drawback that contact pressure is insufficient and electrical contact failures are likely to occur. @Figure 3 (b) This is the contact side for flat battery B, with 37 facing each other, but the contact piece 36 is attached to the battery case, and the contact piece 37 is attached to the battery cover. , the terminal from the contact piece 37 must be electrically connected to the connecting piece 39 provided in the battery case, which can easily cause a connection failure.For both of the above two rows, remove the flat batteries from the battery case. The disadvantage is that it is not easy to

[Problem that the invention seeks to solve]

It is easy to install and remove the flat battery, and the battery 'I
It is an object of the present invention to provide a flat battery having a structure that allows reliable connection to a power source.

[Defined means of solving problems]

The present invention aims to achieve the above object, and the present invention F
i A contact having a soil wall that locks the tip of the battery when the battery is inserted, and a bottom wall having a recess S that forms a slide guide surface of the VC4IC cell when the battery is inserted, and a contact portion inside the tip of the upper wall. The present invention provides a structure of a flat FFI battery plug characterized in that a piece is provided on the bottom wall.

[Implementation row]

Figure F1 shows a side sectional view of one implementation row of the present invention. Figure 1 (1) shows the street where the flat IE pond B is to be installed, and Figure 1j41 (bl is the installation Indicates the condition.

11 is a dish-shaped battery case made of insulating material such as night fat, and the inner bottom wall has a recess 1ls11. A lower contact piece 12 is provided, which has a recessed portion 11a, a support portion 11a, a spring-like shape, and a contact portion 12m at its tip.

The battery case IIIC has an upper wall part 13 fixedly installed so as to partially cover the inner surface. Of course, the battery case 11 and the upper wall member 13 may be integrated.
ij slightly protrudes on the end surface near the center of the inner side! tCI
! An upper contact piece 14 is attached to the first part 14a and the whole 14. This upper wall member 13 has the function of protecting the contact piece 14 both structurally and electrically.

The contact piece 12 and the contact piece 14 are attached so that the flat battery B is separated from the battery B by more than the thickness of the battery B, and the flat battery B is inserted between them. The concave portion 111 of the spindle 17 forms an inclined surface that guides the tip when inserting the 1,000 mtaB when inserting the flat battery B as indicated by ■→■ in FIG. 1(a).

Insert the flat battery into the flat battery chamber with such a structure so that it stands up in the BFi battery case 11, and while locking it to the upper member 13, insert the
If you push it in gradually along the 1 m length, it will be flat.

b, resulting in the state shown in FIG. 1(b). 15 is the battery capacity.

This is where a strong spring force is applied in advance to the contact piece 12, and since the contact pieces are facing each other when the parrot is loaded, there is a high contact pressure between one pond and the magnetic piece. can be maintained. In addition, during the process of inserting the battery, the contact portion of the piece came into contact with the battery and self-cleaned, eliminating the occurrence of poor contact.

When taking out the flat type '4 Ugly B from the battery compartment, when the battery quantity 15 is removed, it will float due to the penetrating pressure of the battery contact piece 12 and can be taken out easily.

FIG. 2 shows an example of application of the present invention, in which the camera is equipped with a date module n for recording information such as the shooting date on the film. A flat battery B is provided as an operating power source for module n.

In this application-1, the back cover 4 is provided at the end portion that covers the film chamber on the film winding side so that the flat battery B is in a position inclined with respect to the camera 20 when the back cover 1i21 is in the closed state. The battery chamber according to the invention is integrally provided inside the back cover. The hollow portion 21aFi having a triangular shape in the cross-sectional view of FIG.
a This is a book equivalent to VC.

〔Effect of the invention〕

The flat battery according to the invention is easy to load and take out the battery, and it takes only 41 seconds to load the battery. Then, the 4m piece is self-cleaning, and the Fi is in the W & cover of the battery.
The debris contacts the battery with sufficient contact pressure to ensure stable and reliable fIt? A flat plate battery chamber will be provided which will be connected to the 11L after the ft air.
