Description

[Detailed explanation of the idea] The present invention relates to an improvement in a battery charger.

For chargers that connect circuits in parallel to charge multiple storage batteries simultaneously and individually, when an indicator light is provided in each charging circuit, it is possible to indicate the energization of each circuit separately, but the disadvantage is that it increases the cost. There is.

Furthermore, when trickle charging is performed, there is no need to display energization throughout charging, and it is sufficient to confirm the energization display only when desired, making it difficult to configure the energization display device at a low cost.

The present invention has been devised in view of these points, and one embodiment of the present invention will be described below with reference to the drawings.

In Fig. 1, reference numeral 1 denotes a main body case, which is composed of a casing 2 and a bottom plate 3 as shown in Fig. 3, and one side 4 of the main case houses charging parts shown in Fig. 2. A plurality of storage battery storage recesses 5, 5 are arranged in parallel on the upper surface of the other side.

An elastic member 6 serving as a charging contact for the cathode is attached to the inner wall of one side 4 of each storage recess 5, and a charging contact for the anode 7 is fixed to the other inner wall.

As shown in FIG. 2, the elastic members 6 are connected to intermediate taps 11 of the secondary coils 10 of the step-down transformer 9 via charging current adjusting resistors 8, respectively, and the charging contacts 7 are connected to rectifying diodes 12 and 12, respectively. It is connected to both ends of the secondary coil 10 via the secondary coil 10 .

The primary coil 13 is connected to a commercial power source to form a trickle charging circuit.

Each elastic member 6 is provided with a proximal pull-out portion 14, which is disposed so as to be in contact with the inner surface of the top plate 15 of the housing 2, and the proximal pull-out portion A push button knob 16 is fixed to the upper plate 15.
It is made to protrude upward from the through hole 17 of.

Next, reference numeral 18 is a energization indicator consisting of a light emitting diode, which is inserted and fixed into the annular rib 20 of the upper plate 15 so as to be exposed through the hole 19 of the upper plate 15, and its cathode terminal 21 is connected to the charging current adjusting resistor 8 and the intermediate tap. 11 connection points, and the anode terminal 22 is connected to a common fixed contact plate 23 mounted oppositely below the distal end of each proximal end pull-out portion 14.

In the above configuration, when the storage battery 24 is stored in the storage recess 5 and the push button knob 16 corresponding to the recess is pressed,
The proximal end drawer portion 14 of the elastic member 6 attached to the storage recess 5
The tip 25 of the common fixed contact plate 23 is connected to the common fixed contact plate 23 as shown by the broken line in FIG.
come into contact with.

Therefore, the voltage across the charging current adjusting resistor 80 corresponding to the storage recess 5 is applied to the energization indicator lamp 18, and the lamp lights up to indicate that charging is in progress.

As described above, according to the configuration of the present invention, it is possible to selectively check whether molding is in progress using one energization indicator light for a plurality of charging circuits.

In addition, the elastic member constituting the charging contact is provided with a proximal pull-out portion,
A push button knob fixed to the proximal pull-out part is exposed on the top surface of the main body case, and a common fixing contact plate is provided that opposes each proximal pull-out part, and the proximal pull-out parts are commonly fixed by pressing the one knob. By making contact with the contact plate and lighting up one energization indicator light connected to this common fixed contact plate, the switch mechanism has a simple structure, and one energization indicator light can be used for multiple charging operations. Since the energization of the circuit can be displayed, an inexpensive charger can be provided.
