Description

Single slot type battery charger for mobile phones {Single slot type charger for battery packs for mobile phone}

The present invention relates to a battery charging device for a mobile phone, and more particularly, a first charging unit capable of charging a battery mounted in a mobile phone and a second charging unit capable of charging a battery separated solely in a single slot formed on an upper surface of a charger case. In each case, when the battery mounted in the mobile phone is placed in the first charging unit, the second charging unit is covered by the battery mounted in the mobile phone, so that the battery cannot be placed alone. If the separated battery is placed, it interferes with the first charging part and forms a structure in which the battery mounted in the mobile phone cannot be placed, thus eliminating the changeover switch and other circuit parts and simplifying the mechanical structure. The present invention relates to a battery charger for a mobile phone, which can reduce and improve productivity.

Conventional mobile phone battery charging device as shown in Figure 1, it is possible to settle the battery 21 separately separated from the first charging slot 10 that can be placed in the battery 11 mounted on the mobile phone (30) The second charging slots 20 are formed in the inclined state in the charger case 40, respectively, and several charging terminals 12 and 22 mounted on the internal charging circuit board 50 of the charger case 40 are Penetrating through the lower portion of the filling slot (10, 20) protrudes into the filling slot (10, 20), respectively.

In addition, in the conventional charging method for a battery charger for a mobile phone, when charging only one of a battery mounted on a mobile phone and a battery separated by a single cell, charging starts as soon as the battery is inserted into the charging slot. In the case of inserting the battery (11) attached to the first charging slot 10 and the separately separated battery 21 into the second charging slot 20 to charge the two batteries together, Batteries 11 and 21 do not start charging at the same time, only the charging path of the first charging slot 10 is turned on to charge the battery 11 mounted in the mobile phone 30 first, and then mounted in the mobile phone 30. When the charging of the battery 11 is completed, the charging path of the second charging slot 20 is sequentially turned on by a switching switch that charges the battery 21 that is separated by itself.

As such, the conventional battery charger for mobile phones requires switching switches and other components necessary for the sequential charging of two batteries, which makes the circuit configuration complicated, making the charging device difficult, and charging for charging the battery mounted in the mobile phone. It is difficult to miniaturize the charger case because the charging slot is separately formed to charge the battery separated from the slot alone, and the two charging slots are inclined so that the parting line may be inclined when manufacturing the mold of the charger case. There is a problem in that a slide core must be used.

The present invention has been made to solve the above-described problems, for a mobile phone having a structure that does not require a switching switch that can be charged only in one battery of the battery mounted on the mobile phone or a battery separated by a single slot type charger case It is an object to provide a battery charger.

According to an aspect of the present invention, there is provided a battery charger device for a mobile phone, including: a first charging unit capable of charging a battery mounted in a mobile phone, a second charging unit capable of charging a separate battery, and a first charging unit; And a circuit unit for applying a charging current to the charging unit and the second charging unit, and a power supply unit for supplying power to each part.

The first charging unit is formed in a shape having a predetermined inclination to be placed inclined on the top of the charging case, the battery mounted in the mobile phone, the lower part of the first charging portion of the first charging terminal located inside the charger case And a first charging terminal hole formed to protrude through the charger case.

The second charging part is formed in a slot shape having a steeper inclination than the first charging part downward from an upper surface of the first charging part so that the battery separated solely in the middle of the upper surface of the first charging part can be placed in a vertical direction. The lower part includes a second charging terminal hole formed so that a part of the second charging terminal located inside the charger case may protrude through the charger case.

In addition, the first charging unit and the second charging unit has a mutually exclusive structure. When the battery mounted on the mobile phone is placed in the first charging unit, the second charging unit is covered by the battery mounted on the mobile phone. The separated battery cannot be placed, and when the battery separated by the second charging unit is placed alone, the battery may interfere with the first charging unit, and thus the battery mounted on the mobile phone cannot be placed. Accordingly, the battery charger for a mobile phone according to the present invention can be charged by placing only one of a battery mounted on a mobile phone and a battery separated by a single cell, thus having a simple structure without a switching switch.

The circuit unit converts a current applied from the power supply unit into a charging current and supplies the charging terminal to the charging terminal, and when the battery mounted in the mobile phone is placed in the first charging unit, the charging circuit is connected to the battery terminal and the battery mounted in the mobile phone The first charging terminal disconnects the charging circuit from the battery terminal when the first charging unit is detached, and the charging circuit is connected to the battery terminal when the battery separated by itself is placed in the second charging unit. The second charging unit includes a second charging terminal which disconnects the charging circuit from the battery terminal when the second charging unit is separated. Therefore, when the battery mounted on the mobile phone or the battery separated by itself is placed in the first charging unit or the second charging unit in a state where power is applied to the power supply unit and current flows on the circuit board, the first charging terminal or the second charging terminal is Charging is performed by applying a charging current flowing through the circuit board to the battery.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;
