Abstract:
A portable relay base, which is composed of an upper cover and at lower cover joined to each other including, at a lateral side thereof, an outlet unit composed of two contact poles and one ground pole and an opening;the portable relay base further comprising: a power line carrier, being a disk shape and fitting with the lower cover axially, including an automatic positioning/wire collecting apparatus, and a central hollow reel at a top thereof with at least two concentric spacing rings; a power line including a lead wire coiled around the central hollow reel with a first end thereof with an electricity plug extending outside the opening and a second end thereof having at least two conductive pieces; and a circuit board fixed to an inner part of the upper cover, including resilient contact pieces touching each of the conductive pieces, wherein the circuit board at an upper face thereof includes at least two concentric guide rings, each of the guide rings is connected to at least a signal output outlet exposed on the upper cover via electrical lines and a second opening is provided on the upper cover; the relay base further comprises a communication line, being a signal wire coiling around the reel with an end with a signal plug extending outside the second opening and another end thereof having resilient terminals corresponding to each of the guide rings, the resilient terminals being fixed to the hollow reel so as to touch the guide rings respectively; whereby, when the power line carrier rotates, power through the electricity taking plug is delivered to each of the outlet units via the at least two connecting wires, and, when the signal line carrier rotates, a signal from the signal plug is delivered to each of the signal outlets via the communication line.
