JPH04220946A - Battery contact of battery box - Google Patents

Abstract

PURPOSE:To permit a battery to be in service even in case it is set in a battery box of any appliance with no respect of battery inserting direction, by adopting the constitution according to the invention as described hereunder. CONSTITUTION:In the battery box 11a of any appliance 11, for example a camera, positive contacts 12, 13 and negative contacts 14, 15 are furnished on the over-side and under-side, respectively, so that they will touch the positive and negative terminals 1a, 1b of a battery 1. In case as illustrated where the battery 1 is set in the battery box 11a in such a way that the positive and negative terminals arc situated up, they will touch the over-side contacts 12, 13 -- in case the battery 1 is inserted in such a way that the terminals are situated down, they will touch the under-side contacts 14, 15. Thus the intended purpose can be implemented.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery contact in a battery box for a camera or other camera using a vertically symmetrical battery such as 2CR5.

0002

2. Description of the Related Art Conventionally, when inserting a vertically symmetrical battery 1, such as a 2CR5 battery having an appearance as shown in FIG.
The person inserting the battery must check the direction so that the contacts and the + terminal 1a and - terminal 1b of battery 1 match, respectively. One side is flat so that it cannot be inserted in the direction in which the positive terminal of the battery 1 contacts the negative contact of the battery box. That is, when inserting the battery 1 from the battery insertion slot 2a of the battery box of the camera 2 as shown in FIG. 4, the battery 1 can be inserted in the orientation of the battery 1A, but cannot be inserted in the orientation of the battery 1B. It has become.

[Problem to be Solved by the Invention] By the way, since the battery 1 is vertically symmetrical, it is often the case that the battery 1 is inserted in the wrong direction and the battery box lid is closed before the camera is turned on. However, the camera may not work, which may confuse the camera user. Furthermore, when there is no time to spare, such as when replacing a battery during photography, it is easy to forget to check the orientation of the battery terminals, and there is a possibility of missing a photo opportunity due to having to replace the battery twice. In particular, many modern cameras use screws to secure the battery box cover using coins, etc., and even though it takes time to replace the battery, it is easy to avoid incorrectly oriented battery terminals. Loosen the screw again with a coin, etc., remove the battery box cover, reverse the direction of battery 1, and close the battery box cover.
If the screws were tightened with a coin or the like, it would take too much time to replace the battery.

SUMMARY OF THE INVENTION An object of the present invention is to provide a battery contact for a battery box that can be inserted into the battery box regardless of the vertical orientation of the battery.

[0005]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a battery box that uses a vertically symmetrical battery such as 2CR5 as a power source, and that when the battery is inserted in a certain direction, the + Two sets of contacts are provided, one that can contact the terminal and the negative terminal, respectively, and the other that can contact the positive and negative terminals of the battery when the battery is inserted in the opposite direction. It is something that

[0006]

[Operation] By having two sets of electrical contacts in the electrical box configured as described above, it is possible to properly contact the + terminal and - terminal on the battery side regardless of the vertical orientation of the inserted battery.

[0007]

Embodiments Hereinafter, embodiments of the present invention will be explained based on FIGS. 1 and 2. In the figure, a + contact 12 and a - contact 13 are provided at the top of the battery box 11a of the camera 11, and a + contact 14 and a - contact 15 are provided at the bottom, respectively, so that the upper and lower opposing polarities are opposite. There is. In this embodiment with the above configuration, when the 2CR5 type battery 1 is inserted into the battery box 11a so that the + and - terminals 1a and 1b of the battery 1 are at the top as shown in FIG.
The + terminal 1a and the - terminal 1b of the terminal 1a and 1b contact the + contact 12 and the - contact 13, respectively, but do not contact the + contact 14 and the - contact 15 at the bottom. Therefore, power from the battery 1 is received from the + terminal 1a and the - terminal 1b of the battery 1 through the + contact 12 and the - contact 13.

Next, as shown in FIG.
Insert the battery box 11a so that the and - terminals 1a and 1b come together.
, the + terminal 1a and - terminal 1b of battery 1
contact the + contacts 14 and - contacts 15, respectively, but do not contact the + contacts 12 and - contacts 13 at the top. Therefore, the power from the battery 1 is the + terminal 1a and the - terminal 1 of the battery 1.
b through the + contact 14 and the - contact 15. By providing two sets of battery contacts in the battery box 11a in this manner, battery power can be supplied to the camera regardless of the direction in which the battery is inserted.

Effects of the Invention As explained above, the present invention provides 2CR5
By providing two sets of battery contacts in the battery boxes of devices that use vertically symmetrical batteries such as the above, you can insert the batteries without worrying about the direction in which they are inserted. Eliminates the hassle of reinserting batteries. Furthermore, batteries can be replaced smoothly when the device is in use.
