Description

[Detailed Description of the Invention] The present invention relates to a portable electric lamp with a charger, which is fitted into a charger during charging and is automatically charged, and which allows only the portable electric lamp to be removed during use.

Conventionally, this type of charger has a box-shaped charger 1 with a corner window 2 provided in a part of the upper surface of the box body into which an electrical device 4 can be inserted, as shown in FIG. By inserting the device 4, the charging terminal 5 provided on the bottom and side surface of the electrical device 4 comes into contact with the terminal 3 provided inside the corner window 2 of the charger 1, and the storage battery in the electrical device 4 is connected. It is for charging.

As a method of connecting the charger 1 and the electric device 4, the weight of the electric device 4 is used to press a push-type switch inside the charger 1, and automatic charging is performed.

However, this type of structure can cause poor contact between the connection terminals, or the built-in storage battery may explode or explode due to charging due to incorrect connection of the terminals.
There was a drawback that the pressing force was insufficient due to the use of the weight of the equipment.

The present invention relates to an electric device with a charger, particularly for a portable lamp, which eliminates the above-mentioned drawbacks, and will be described in detail below with reference to an embodiment.

In FIG. 2, reference numeral 11 denotes a charger that incorporates a charging circuit A configured with the circuit shown in FIG. , 14 is a convex portion protruding from the wall surface 13, 15 is an output terminal of the built-in charging circuit A formed on the convex portion 14,
16 is a reed switch connected to the charging circuit A, 17 is a portable lamp with a built-in storage battery B, 18 is a light emitting part, 19 is a handle, 20 is a switch, 21 is a recess that fits into the convex part 14, and 22 is a terminal 15 recess 2 in a position where it can come into contact with
A terminal 23 led out from the storage battery B provided in the reed switch 1 is a permanent magnet provided at an opposing position to turn on the reed switch 16.

According to the above configuration, the portable electric lamp 17 is fitted into the fitting part 12 of the charger 11 in a sliding manner along the wall surface 13 so that the protrusion 14 is inserted into the recess 21.

Conversely, by lifting the handle 19 upward, only the portable light 17 can be easily removed from the charger 11.

Furthermore, if the bottom of the portable light 17 is fitted to the top of the charger 11, the terminal 15 of the charger 11 and the terminal 22 of the portable light 17 are connected.
are in contact with each other, and charging circuit A and storage battery B are connected and ready to start charging.

At this time, the reed switch 16 provided on the surface of the charger 11 that comes into contact with the portable electric lamp 17 is turned on by the magnetic force of the permanent magnet 23 of the portable electric lamp 17, and charging begins.

The charging circuit A and the storage battery B are connected as shown in the circuit shown in FIG. 3, and since the reed switch 16 is inserted and connected between the AC power source 24 and the charging circuit A,
If the reed switch 16 is in the off state, the AC power supply 24
Therefore, no current flows through the charging circuit A, and no voltage is normally applied to the terminal 15 to prevent electric shock. When it is time to charge, the battery is automatically charged, and when the charging is completed, trickle charging and charging are automatically stopped. If the circuit is built-in, there is no need for a power switch.

With the above configuration, the terminal 22 of the mobile light 17 can be connected to the recess 21.
Since the fitting portion 12 is provided within the wall surface 13, short circuits due to contact are prevented, and since the fitting portion 12 is surrounded by the wall surface 13, erroneous positive and negative terminal connections are prevented.

Furthermore, in case of a box-shaped or cylindrical portable electric light having a shape other than that shown in the drawings, erroneous connection can be prevented by changing the shape of the concave and convex parts depending on the fitting part.

Furthermore, by providing a fitting part formed with unevenness on both sides, and by providing a terminal on the uneven part, electrical connection can be made reliably, and charging can be automatically stopped. For example, the charger 11 can be used as a stand or a storage space without overcharging.

Note that the positions where the uneven portions, magnets, and reed switches are provided are not limited to the above-mentioned positions; if they are placed in a portable lamp, the same effect can be obtained even if they are formed vertically.
As mentioned above, the present invention, which can be modified depending on the mode of use, has a structure that includes a storage battery in the portable lamp and a charging circuit in the charger to ensure charging.
It can also prevent short circuits and incorrect connections, and has great practical value.
