<p><P>PROBLEM TO BE SOLVED: To provide a ceiling hanging socket in which power supply and information communication are compatible while avoiding adverse affect of noise. <P>SOLUTION: The ceiling hanging socket includes a main unit 3 prepared at an end of a string 2, which can freely lift and drop; an optical curled code 4 whose one end is put in a support 1, and another end is pulled in the main unit 3; a power supply curled cord 5 whose one end is put in the support 1, and another end is pulled in the main unit 3; an optical receptacle 6 connected to the end of the optical curled code 4 in the main unit 3; and a socket 7 connected to the end of the power supply cord 5 in the main unit 3. The power supply and the information communication are compatible while avoiding the adverse affect of noise, since there is no mutual adverse affect between a power supply line (power supply curled cord 5) and an optical fiber optics (optical curled code 4) employed as a medium for the information communication. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
