ーダと電源コードが邪魔になることは申すまでも無い。The portable communication device referred to here is mainly a small or ultra-small transceiver called a handy type or a personal type, and the internal power battery is extremely small and has a small capacity due to the volume and weight. Limited. Therefore, when used in a vehicle, it is natural to use a vehicle battery as an external power source. In such cases, conventionally, as shown in FIG. 1, the feeder 5 of the external antenna 4 is connected to the antenna terminal 2 of the communication device 1, and the cord 6 of the vehicle battery is connected to the external power terminal 3. However, since the microphone is built-in in such a small device, it is necessary to bring it to the mouth when transmitting, and needless to say, the antenna feeder and power cord get in the way.

電源で動作するものである。As described in the claims and exemplified in FIG. ) The antenna feeder 5a passes through the DC branch circuit 15 provided between the antenna feeders 5a and 5b.
This is an external power supply connection method, in which the power is supplied to the power supply circuit of the communication device through a DC branch circuit provided in the antenna input circuit of the communication device 10, and an example thereof is shown in FIG. The antenna feeder 5a connected to the antenna terminal 2 of the communication device is connected to the DC branch circuit 15 feeder 5b.
The external power supply is connected to the high frequency choke 21 within the DC branch circuit P through the power cord 6.
Through the feeder 5a, it flows into the inner part of the communication device from the antenna terminal 2, and flows into the antenna 4 through the feeder 5a.
2, direct current is blocked and only high frequency current flows. C is a high frequency bypass capacitor,
In reality, it is necessary to provide a strict filter to prevent power supply noise from entering the antenna circuit, and only the minimum configuration is shown in the figure. Inside the communication device 10, a capacitor 11 and a high-frequency choke 16 constitute a DC branch circuit, and high-frequency waves pass through the capacitor 11, pass through the transmitter/receiver switch 12, and connect to the transmitting section 13 and the receiving section 14, and the direct current passes through the choke 16. , a reverse current blocking diode 17, and a power switch 15 to connect to an internal power supply circuit. The internal battery 19 is connected to the internal power supply circuit through the reverse current blocking diode 18, so if there is no external power supply, the internal battery will operate, and if an external battery with a higher stain pressure than the internal battery is connected, it will automatically shut down. It operates on an external power supply.
以上に述べたように本発明の外部電源接続方式によれば
通信機１０にはアンテナフィーダ５ａが接続されるのみ

のである。As described above, according to the external power supply connection method of the present invention, only the antenna feeder 5a is connected to the communication device 10, and since the external DC branch circuit 4 is in the shape of a slight grain, the external It is easy to install it near the antenna lead-in part, and there is no problem in implementation.
