Claims

[Scope of utility model registration request]

When connecting the self-sufficient power source and the communication line to telephones and intercoms that require network power supply and self-sufficient power source through the communication line,
a wall-embedded box into which the AC power line that generates the self-sufficient power source and the communication line are respectively introduced;
The device includes a DC power adapter that converts AC supplied from the AC power line to DC, and a modular jack that is attached to the wall-mounted box, and the modular jack is connected to the communication line. A modular plug has a communication line terminal and a self-sufficient power supply terminal that outputs the self-sufficient power supply via the DC power adapter, and connects the communication line terminal and the self-sufficient power supply terminal to the telephone/intercom via a connecting cable. A self-sufficient power connection structure for telephones and intercoms that is detachable.
