摘要

Disclosed is a DC power supply of a DC application. A DC power supply of a DC application device including a printed circuit board provided with a power supply terminal and a wire communication terminal, comprising: a pair of power lines, each of which is electrically energized with a DC power supply and spaced at regular intervals, between the power lines; An attachment plate having a pair of communication lines provided for wired communication, and installed to be exposed from a wall or a ceiling; The power supply terminal is composed of a positive terminal and a negative terminal, the positive terminal and the negative terminal is provided so as to project from the printed circuit board spaced apart at regular intervals so as to contact the pair of power lines, the communication terminal is The printed circuit board protrudes from the printed circuit board so as to be in contact with a communication line. The printed circuit board may include the power supply terminal contacting and disconnecting the pair of power lines, and the communication terminal contacting and disconnecting the communication line. And a plurality of magnets installed in a portion adjacent to the plus terminal and the minus terminal.
