30 : 전화기 회로 L1, L2 : 전원라인30: telephone circuit L1, L2: power line

본 고안은 무선전화기의 전원장치에 관한 것으로, 특히 전원 장치를 구비한 무선전화기에 있어서 전원장치에 충전장치를 부가하여 정전시에도 무선전화기 사용이 가능토록 하는 전원장치에 관한 것이다.The present invention relates to a power supply device for a cordless phone, and more particularly, to a power supply device for adding a charging device to the power supply device so that a cordless phone can be used even in a power failure.

일반적으로 유선전화기는 교환시스템으로 부터 공급되는 통화공급전원(-48V)에 의해 동작하도록 되어 있으나, 무선전화기는 별도의 전원공급을 필요로 한다. 이에따라 무선전화기는 동작 전원을 공급하기 위한 전원장치를 구비하고 있으며, 상기 전원 공급장치는 110V 또는 220V교류의 상용전원을 일정 전압으로 강압하고 정류하여 직류전원을 무선전화기에 공급한다. 그리고 통상적으로 상기와 같은 전원장치로서 어댑터(adapter)가 사용된다.In general, wired telephones are operated by a call supply power (-48V) supplied from an exchange system, but wireless telephones require a separate power supply. Accordingly, the wireless telephone is provided with a power supply for supplying the operating power, the power supply device to step down and rectify the commercial power of 110V or 220V AC to a predetermined voltage to supply DC power to the wireless telephone. In general, an adapter is used as the power supply as described above.

그러므로 상기한 바와같이 어댑터에 의한 직류전원을 공급받아 동작하는 종래의 무선전화기는 정전시에는 사용이 불가능한 문제점이 있었다. 또한 정전시를 대비하여 유선전화기와 병행하여 사용해야만 하는 문제점이 있었다.Therefore, as described above, the conventional wireless telephone operating by receiving DC power by the adapter has a problem that it is impossible to use it in case of power failure. In addition, there was a problem that must be used in parallel with a landline telephone in case of power failure.

따라서 본 고안의 목적은 무선전화기의 전원장치에 있어서, 충전장치를 부가하여 평상시에 충전시켜 정전시에 충전된 전원을 무선전화기에 공급함으로써 정전시에도 무선전화기의 사용이 가능토록 할 수 있는 전원장치를 제공함에 있다.Accordingly, an object of the present invention is to provide a power supply device for a cordless phone, which can be used in case of a power outage by adding a charging device to supply the charged power to the cordless phone at the time of power failure. In providing.

이하 본 고안을 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제 1 도는 본 고안에 따른 전원장치의 일실시에의 회로도로서, 전원라인(L1, L2)으로 부터 입력되는 교류 상용전원을 일정전압으로 강압하기 위한 트랜지스포머(transformer)(12)와, 상기 강압된 교류전원을 정류하여 직류전원으로 변환하는 정류회로(14)를 구비한 어댑터(10)와, 상기 어댑터(10)의 출력 직류전원에 의해 동작하여 무선전화 기능을 수행하는 전화기회로(30), 상기 어댑터(10)의 출력단자에 상기 전화기회로(30)와 병렬접속되어 상기 어댑터(10)의 출력 직류전원을 충전하며 정전시 충전된 직류전원을 방전하여 상기 전화기회로(30)에 공급하는 충전장치(캐패시터)(20)로 구성된다. 상기 제 1 도의 구성중 충전장치(캐패시터)(20)는 전화기회로(30)와 함께 무선전화기 본체에 위치한다.1 is a circuit diagram of one embodiment of a power supply apparatus according to the present invention, a transformer 12 for stepping down AC commercial power input from power lines L1 and L2 to a constant voltage, An adapter 10 having a rectifying circuit 14 for rectifying the stepped down AC power and converting the DC power into a DC power source; and a telephone circuit operated by an output DC power source of the adapter 10 to perform a wireless telephone function. 30) connected to the output terminal of the adapter 10 in parallel with the telephone circuit 30 to charge the output DC power of the adapter 10 and discharge the charged DC power at the time of power failure to the telephone circuit 30 It is composed of a charging device (capacitor) 20 for supplying. The charging device (capacitor) 20 in the configuration of FIG. 1 is located in the main body of the wireless telephone together with the telephone circuit 30.

이하 본 고안에 따른 제 1 도의 동작예를 상세히 설명한다.Hereinafter, an operation example of FIG. 1 according to the present invention will be described in detail.

지금 제 1 도의 전원라인(L1, L2)을 통하여 110V 또는 220V의 교류 상용전원이 어댑터(10)의 트랜스포머(12)에 입력되면, 일정전압으로 강압되고 정류회로(14)에서 정류됨으로써 직류전원으로 변환되어 전환기회로(30)의 전원입력단자에 입력된다. 그러므로 상기 전화기회로(30)가 동작하며 통상적인 무선전화 기능을 수행할 수 있게 된다. 여기서 상기 트랜스포머(12)의 출력전압은 상기 전화기회로(30)를 동작시키기 위한 전압이다.When AC commercial power of 110V or 220V is input to the transformer 12 of the adapter 10 through the power lines L1 and L2 of FIG. 1, it is stepped down to a constant voltage and rectified by the rectifying circuit 14 to be a DC power source. The signal is converted and input to the power input terminal of the switch circuit 30. Therefore, the telephone circuit 30 operates and can perform a normal wireless telephone function. The output voltage of the transformer 12 is a voltage for operating the telephone circuit 30.

이때 상기 정류회로(14)의 출력 직류전원은 충전장치인 캐패시터(20)에 충전됨으로써, 정전시에 충전된 직류전원을 방전하여 전화기회로(30)에 공급하게 된다. 그리고 충전시의 전류 흐름은 화살표 방향(K1)과 같고 방전시에 전류 흐름은 화살표방향(K2)과 같다.At this time, the output DC power of the rectifier circuit 14 is charged in the capacitor 20 as a charging device, thereby discharging the DC power charged at the time of power failure to supply to the telephone circuit 30. The current flow at the time of charging is the same as the arrow direction K1 and the current flow at the time of discharge is the same as the arrow direction K2.

따라서 정전시에도 무선전화기의 사용이 가능해진다.Therefore, it is possible to use a wireless telephone even in the event of a power failure.

제 2 도는 본 고안에 따른 다른 실시에의 회로도로서, 충전장치(캐패시터)(20)를 어댑터(10)내에 설치하여 구성한 것으로 동작을 전술한 제 1 도와 같다.2 is a circuit diagram according to another embodiment of the present invention, in which a charging device (capacitor) 20 is installed in the adapter 10, and the operation is the same as the first diagram described above.

상술한 바와같이 본 고안은 무선전화기의 전원장치에 충전장치를 부가하여 평상시에 직류전원을 충전시키고 정전시 충전된 직류전원을 방전하여 무선전화기에 공급함으로써 정전시에도 무선전화기의 사용이 가능하게 되는 잇점이 있다.As described above, the present invention adds a charging device to the power supply unit of the wireless telephone to charge the DC power at normal times, and discharges the charged DC power at the time of power failure to supply the wireless telephone to use the wireless telephone even during a power failure. There is an advantage.
