Description

TECHNICAL FIELD The present invention relates to an adapter device for charging a battery such as a small sealed storage battery.

2. Description of the Related Art In recent years, with the rapid spread of portable VTRs, various power supply systems for driving them have been developed. In such a situation, a battery pack containing a small sealed storage battery such as a nickel-cadmium storage battery, an AC adapter supplying power from an AC commercial power supply, a battery charging adapter containing a control circuit for rapidly charging the battery pack, Power supply systems with such configurations have become common.

Of these, for a relatively expensive battery charging adapter, how easy and cheap it is to make is very important in terms of widespread use.

The conventional battery charging adapter device will be described below.

In FIG. 6, 1 is a lid, 2 is an upper case, 3 is a lower case, and 4 is a hinge. The hinge 4 has a lid 1, an upper case 2,
Alternatively, it is attached to the lower case 3 and the lid 1 is opened and closed. This requires a large number of parts called hinges 4 and is difficult to assemble.

FIG. 7 shows another example, in which reference numeral 5 is a fastening component of the lid 1, which is mounted between the upper and lower cases 2 and 3. The lock mechanism of the lid 1 can also be realized by using this part, but at least two fastening parts are required.

Problems to be solved by the invention In both of these, there was a problem that the cost was low and the assembly work could not be simplified.

The present invention solves the above conventional problems.

Means for Solving Problems The battery charging adapter device of the present invention comprises an outer case composed of a synthetic resin lid, an upper case and a lower case, and a printed circuit board inside the upper and lower cases. In addition to incorporating the unit, the lid has a mechanism for locking it integrally formed on both sides, and the lid lock mechanism is located at a predetermined position of the upper case and the lower case. It was assembled by sandwiching it without any.

By thus sandwiching the lid itself between the upper and lower cases, it is possible to perform the function as a locking device, and the locking mechanism portion integrally formed with the lid has a
The lock can be positioned by providing two protruding and retractable protrusions that are separated by 80 °.

Embodiment An embodiment of the present invention will be described below with reference to FIGS.
In the figure, 6 is a lid, 7 is an upper case, 8 is a lower case, 9 is a battery contact terminal, 10 is a battery holder, 11 is an AC adapter contact terminal, 12 is an AC adapter holder, 13 is an AC adapter, and 14 and 15. Is a battery pack to be charged, 16 is a printed circuit board unit, 17 is a fastening screw, 6a is a lid locking mechanism, 7a is an upper case locking mechanism, and 8a is a lower case locking mechanism.

To assemble the adapter device, as shown in FIG. 4, a lock mechanism portion 6a is integrally formed on both left and right sides of the lid 6 which rotates.
Is incorporated into the lock mechanism portion 7a of the upper case 7, and the printed circuit board unit 16 is sandwiched between the upper case 7 and the lower case 8 by the two screws 17 penetrating the upper case 7 and the lower case 8. Assemble.

The printed circuit board unit 16 includes a battery contact terminal 9 and an A
A C adapter contact terminal 11 is incorporated. As shown in FIG. 3, the battery holder 10 includes a battery pack 14,
The battery pack is held by fitting the concave portions of the case of 15. By fitting the recess of the case of the AC adapter 13 into the holder 12 for AC adapter,
Hold the adapter.

The battery contact terminal 9 is for making contact with the terminal of the battery pack, and the AC adapter contact terminal 11 is for the AC adapter 1.
It is for making contact with the terminal of 3. As shown in FIG. 5, the lock mechanism portion 6a of the lid is provided with 18
There are two protrusions 6b which can be retracted and retracted by springs at two places apart from each other by 0 °, and the recess 7b of the lock mechanism 7a of the upper case
The lock mechanism portion 8a of the lower case is fitted and assembled into the concave portion 8b. As a result, when the lid 6 is closed,
It is locked and kept in that state, and is locked even when the lid 6 is opened 180 degrees.

In the state of FIG. 3, the AC adapter 13, the battery packs 14 and 15 are fitted to the battery charging adapter, and A
When the AC cord plug of the C adapter 13 is inserted into the AC applied power source, the battery packs 14 and 15 are charged through the charge control circuit in the battery charging adapter. Note that even one battery pack can be charged.

Effects of the Invention As described above, according to the present invention, the following effects can be obtained.

(1) It is extremely easy to assemble with a simple case structure.

(2) The lid locking mechanism can be easily configured.

(3) The lock mechanism cannot be seen from the outside, and the appearance of the adapter device can be improved.
