The other end of the electric wire 80 is electrically connected to an external alternating current power source. In the present embodiment, each of the power sockets 15 is connected to three conductive wires 60 respectively inserted into the conductive liquid 53 in the three storage tanks 52. The three wires 80 are respectively connected to the live wire, the neutral wire and the ground wire of the AC power source.
使用時,市電藉由電線80、導電組件50的導電液53和導線60連通至該基台10的電源插座15上,以對該基台10上的電子設備供電。該基台10旋轉,帶動支架16、導線60及蓋體56一起旋轉,這樣便不會出現測試轉台轉動過程中線纜絞線的情況。In use, the mains is connected to the power outlet 15 of the base 10 by wires 80, conductive liquid 53 of the conductive assembly 50, and wires 60 to power the electronic devices on the base 10.
