Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a battery case connected to an electronic device such as a video camera.

[Summary of the Invention] In a battery case in which an external connection electrode is exposed on the case body and electrical connection with an electronic device is possible, the invention as set forth in claim 1 provides a battery case in which the external connection electrode is removable. Hiding with an insulating cover makes it possible to prevent current short-circuiting and leakage at externally connected electrodes.

The invention set forth in claim 2 is characterized in that the insulating cover is integrally formed with the case body in a removable manner. Since the insulating cover of the used battery case is removed due to the irreversible engagement, it is obvious at a glance whether the battery case is used or not.

Furthermore, in the invention described in claim 4, since the insulating cover is removably engaged with the case body, it is possible to insulate the externally connected electrodes again when the battery is used halfway. becomes.

Furthermore, the invention as set forth in claim 5 makes it possible for the insulating cover to come into contact with the external connection electrode of the electronic device to prevent the electronic device from being attached to the case body. Since the battery case cannot be attached to an electronic device with the battery case attached, it is easy to check whether the insulating cover is present or not, and malfunctions of the electronic device can be prevented.

[Prior Art] For example, in a video camera, generally, as shown in FIG.
A battery case 3 can be detachably attached to the battery case 3.

Positive and negative terminals 4 and 5 are provided on the battery case mounting surface 2 on one side of the video camera body 1.
, 5 protrudes a predetermined length from the battery case mounting surface 2 by the force of a spring (not shown), and when its tip is pressed, it retracts toward the battery case mounting surface 2, and when the pressing force is released, it protrudes by a predetermined length by the force of the spring. The length is protruding.

Also, the battery case 3 that overlaps the battery case mounting part 2
Positive and negative terminal plates 7 and 8 are provided on the joint surface 6 of the terminal so as to be exposed.

Then, the battery cases 3 are stacked on top of each other in alignment with the alignment line 11 so as to be sandwiched between a pair of guide projecting plates 9 and 1o provided parallel to the upper and lower parts of the battery case mounting surface 2, and then the battery cases 3 are When it is slid to the right in FIG. Matching groove 1.4. , +5,
The battery case 3 is attached to a battery case attachment surface 2 of the video camera body 1.

Such attachment of the battery case is the same for electronic devices other than video cameras.

[Problems to be Solved by the Invention] However, in such a battery case 3, as shown in FIG.
Since the battery case 3 is exposed, for example, when the battery case 3 is stored in a bag or the like, there is a problem that a conductive object such as a key chain may touch both terminals. Conventionally,
VTRs with built-in video cameras consume a lot of power, so
It was designed for use with nickel-cadmium (Ni-Cd) rechargeable batteries. Therefore, if both terminals were short-circuited, there was a risk that the temperature of the battery would rise. Therefore, in order to prevent this, the battery case is carried around in a plastic case, and the battery case is removed from the plastic case before use.

In addition, in recent years, the power consumption of video cameras has been reduced to 5.5 A or less, and it is now possible to operate for more than an hour with 3 or 6 AA alkaline batteries. As video cameras have become smaller, more and more people are carrying them with them when traveling, but with Ni-Cd rechargeable batteries, you have to carry a charger with you, and you also have to carry a charger with you. Demand for disposable batteries is increasing because luggage is bulky because people don't have to throw them away. Even when this disposable battery is used, there is a problem in that it is uneconomical to use a plastic case for each battery case to prevent short circuits.

Furthermore, the batteries stored in the battery case may be short-circuited.

A known method for preventing electrical leakage is to cover the protruding positive electrode of the battery with paper tape. However, if the battery is stored in the battery case while covered with paper tape, the paper tape may be If you forget to remove the paper tape, you may not be able to start shooting.

If the battery case and battery are stored separately in a bag, for example, there are problems such as it takes time to start shooting and it takes up a lot of space in the bag.

The present invention has been devised by focusing on these conventional problems, and aims to prevent electrical leakage and leakage from externally connected electrodes, save space, and ensure reliable start-up of electronic equipment. The aim is to create a battery case that makes this possible.

[Means for Solving the Problem] Therefore, the invention as set forth in claim 1 provides a battery case in which external connection electrodes are exposed on the case body and electrical connection with electronic equipment is possible. The solution is to hide the electrodes with a removable insulating cover.

The invention recited in claim 2 provides a solution in that the insulating cover is removably formed integrally with the case body.

The invention as set forth in claim 3 provides a solution in that the insulating cover is engaged with the case body in a manner that it cannot be reattached.

The invention set forth in claim 4 provides a solution in that the insulating cover is removably engaged with the case body.

The invention as set forth in claim 5 has a solution in that the insulating cover is brought into contact with an external connection electrode of the electronic device to prevent the electronic device from being attached to the case body.

[Function] In the invention set forth in claim 1, the insulating cover hides the external connection electrode and prevents short circuits and leakage caused by a conductive object such as a key chain coming into contact with the external connection electrode. In the invention set forth in claim 2, the insulating cover is integrally formed with the case body of the battery case, and the function when the battery is housed is the same as the invention set forth in claim 1 above. If the insulating cover is removed when using the electronic device, the external connection terminals of the battery case will be exposed, allowing electrical connection to the electronic device.

According to the third aspect of the invention, the insulating cover similarly has the function of preventing short circuits and leakage at external connection electrodes, and
When the insulation cover is removed from the case body during use,
It cannot be reattached. Therefore, the invention as set forth in claim 4, which is characterized by easy determination of which battery case is used, has the effect of preventing short-circuit 1 leakage at the insulating cover or externally connected electrode. In addition, when you stop using an electronic device and remove the battery case from the electronic device, you can re-insert the insulating cover into the case body to hide the external connection electrodes on the case body again. Become.

In the invention set forth in claim 5, the insulating cover has the effect of preventing conductive objects from coming into contact with the external connection electrodes of the case body, and the insulating cover is attached to the electronic equipment and the battery. Attachment of the case is obstructed, and as a result, the insulating cover must be removed from the battery case before it can be attached to the electronic device, thereby preventing mistakes in removing the insulating cover.
