Description

  The present invention relates to a battery charger with an outlet.

Batteries are generally used as power sources for small electric appliances, flashlights, mobile phones, digital cameras, and the like. However, receivable batteries that can be used repeatedly are becoming widespread from the viewpoints of environmental protection and cost reduction.
At present, various types of battery chargers are on the market for charging such batteries, but generally known battery chargers (see Patent Document 1, Patent Document 2, and Patent Document 3) The battery is simply charged and has no other function.
Moreover, as shown in FIG. 6, since the battery charger D is matched with the dimension of the battery A, it has a considerable size. For this reason, when the battery charger D is inserted into the power outlet B1, the battery charger D also covers the adjacent power outlet B2, and other electrical devices cannot be used.

  The battery charger with an outlet of the present invention comprises a pedestal and an outlet installed on the surface of the pedestal, and the pedestal is provided with a blade portion that can be connected to a battery storage portion and a power outlet, and the battery storage portion and the blade Are connected via a charging circuit, and a circuit for supplying power from the blade to the conductive terminal is provided between the conductive terminal installed in the outlet of the outlet and the blade. .

It is also possible to provide a switch between the conductive terminal and the blade portion for controlling energization of the circuit.
An overload protection device may be provided in the circuit between the conductive terminal and the blade portion to open and cut off the current when the current flowing through the circuit is overloaded.

According to the first aspect of the invention, not only can the battery be charged, but it can be used as a power source for other electrical equipment, and a plurality of power outlets can be occupied when charging the battery. Can be eliminated.
According to the second aspect of the present invention, it is possible to easily control the energization of the electrical equipment connected to the outlet simply by opening and closing the switch.
According to the third aspect of the present invention, since the energization is automatically cut off when the load on the outlet becomes too large, the safety is improved.

The battery charger with an outlet of the present invention includes a pedestal and an outlet installed on the surface of the pedestal. A blade that can be connected to the battery compartment and the power outlet is provided on the base.
The battery storage unit and the blade unit are connected via a charging circuit, and the power taken in from the external outlet can be charged into the battery stored in the battery storage unit. You may enable it to accommodate a some battery in a battery accommodating part.
A circuit for supplying electric power from the blade portion to the conductive terminal is provided between the conductive terminal and the blade portion installed in the outlet of the outlet. It is desirable to provide a plurality of outlets so that power can be supplied to a plurality of electrical devices.
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 to 3 show a first embodiment of the present invention.
As shown in FIG. 1, the battery charger with an outlet includes a base 1 and one or more outlets 2.
On the surface of the pedestal 1, a battery storage portion 11 that can store a plurality of batteries is formed, and terminals corresponding to the batteries to be stored are installed in the battery storage portion 11.
As shown in FIG. 2, a charging circuit 12 is provided in the base 1, and the charging circuit 12 is connected to a terminal installed in the battery storage unit 11.
Further, a pair of blade portions 13 are provided on the back surface of the base 11 (FIG. 1), and these blade portions 13 are connected to the charging circuit 12 (FIG. 2).
In addition, as shown in FIG. 1, the indicator lamp 14 is installed in the appropriate location of the outer surface of the base 1. As shown in FIG.

The outlet 2 is installed on the surface of the base 1 and has a pair of insertion ports 21. As shown in FIG. 2, conductive terminals 22 are provided inside each insertion port 21, and the conductive terminals 22 and the blade portion 13 are connected to a circuit 23.
The circuit 23 is provided with a switch 24 that can be opened and closed from the outside of the pedestal 1, and the energization of the circuit 23 can be controlled by opening and closing the switch 24.
The switch 24 can be omitted.

This battery charger with lighting device is used as follows.
As shown in FIG. 3, the blade 13 extending from the base 1 is connected to the power outlet B, the battery A that needs to be charged is stored in the battery storage 11, and the battery A terminal and the battery storage 11 are installed. Connect the connected terminals. Then, electric power is supplied from the power outlet B to the terminal in the battery storage unit 11 through the blade part 13 and the charging circuit 12, and the battery A is charged.
When charging is completed, the indicator lamp 14 is turned on to notify the end of charging.
At the same time, the plug C of another electric appliance is inserted into the insertion port 21 of the outlet 2, the plug C and the conductive terminal 22 are brought into contact with each other, the switch 24 is closed, and the blade portion 13 and the circuit 23 are connected from the power outlet B. It is also possible to supply power to the plug C.

FIG. 4 shows a second embodiment of the present invention.
The conductive terminal 22 of the outlet 2 is connected to the blade portion 13 via a circuit 23 in which the switch 24 is not provided.
Since other configurations are the same as those of the first embodiment, the same portions are denoted by the same reference numerals, and detailed description thereof is omitted.
