Abstract

PURPOSE:To fix not only a battery but also a plug device to a battery charger main body by means of a battery attaching/detaching lever. CONSTITUTION:A rib 6a for fixing batteries and another rib 6b for fixing plug blades of plug devices are integrally formed with a battery attaching/detaching lever 6 by molding a synthetic resin and the lever 6 can independently fulfill two functions of fixing batteries and fixing plug blades 4c.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a charger having a main body case and a battery attaching / detaching lever that sandwich a battery, charge the battery, and have a plug device that can be stored in the main body case.

[0002]

2. Description of the Related Art As shown in FIG. 4, a charger generally fixes a battery by sandwiching it between a battery fixing rib 1a provided on a main body case 1 and a battery fixing component. Further, in the charger having the plug device 4 that can be stored in the main body,
The fixing of the battery, the housing of the plug, and the holding of the protruding state are performed by independent component configurations, and the structure thereof is generally complicated.

In particular, since the battery attaching / detaching lever 3 as a battery fixing part holds the battery, a conductive material such as a coil spring 3a or a leaf spring is used, and sufficient electrical insulation is required.

[0004]

SUMMARY OF THE INVENTION The present invention solves the problem of ensuring the electrical insulation of a conventional battery charger, and fixes the battery by utilizing the elasticity of the synthetic resin forming the battery attaching / detaching lever. In addition, the plug blade of the plug device capable of storing and projecting is also fixed.

[0005]

Therefore, the charger of the present invention has a battery attaching / detaching lever in which a rib for fixing the battery and a rib for fixing the plug device are integrally formed of resin.

[0006]

The charger of the present invention performs two functions of fixing the battery and fixing the plug device with one battery attaching / detaching lever. The rib for fixing the plug device on the battery attaching / detaching lever is for fixing the battery. Is not affected by the operation of the ribs for
Since they are always held stationary, they can perform their respective functions independently.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A charger according to an embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 and 2 are a main body case, 1a is a battery fixing rib, 6 is a battery attaching / detaching lever, and 6a.
Is a rib for fixing the battery, 6b is a rib for fixing the plug device, 6c
Is an engaging groove formed in the rib, 4 is a plug device, 4a is a base portion, and 4b is an engaging protrusion. The battery attaching / detaching lever 6 in which the ribs 6a and 6b are integrally formed of synthetic resin is fixed to the main body case 1 of the charger. This is combined with the main body case 2 having the plug device 4 pivotally supported.
Then, as shown in FIG. 2, by utilizing the elasticity of the battery fixing rib 6a, the rib 6a can be moved to easily attach and detach the battery. Further, as shown in FIG. 3, by rotating the plug device 4, the engagement protrusions 4 provided on the base portion 4a.
b engages with the engaging groove 6c of the plug device fixing rib 6b and can be fixed in a state where the plug blade of the plug device is projected.

[0008]

As described above, in the battery charger of the present invention, the ribs for fixing the battery and the ribs for fixing the plug device are integrally formed of synthetic resin, and each rib can independently function. Therefore, the battery and the plug device can be easily fixed to the main body case in a predetermined state by the main body case and the battery attaching / detaching lever without requiring a complicated mechanism, which is extremely advantageous in practical use.
