1. A tile for forming a ground power supply line comprising:
- a supporting structure made of electrically insulating material;
an external conductive plate, arranged on an upper surface of said supporting structure and fixed to said supporting structure;
wherein said supporting structure has;
a first channel for a first portion of conductor which, in use, is connected to a first polarity of an electric generator;
a second channel for a second portion of conductor which, in use, is connected to a second polarity of said electric generator;
said second channel being parallel and electrically isolated from said first channel;
and an electric connection assembly, which is accommodated in said supporting structure and includes;
an electric connector in contact with said external conductive plate along said upper surface,a pair of electric connectors arranged at said first and second channels, respectively, to come in contact with said first and second portions of conductor;
a normally open switching element; and
a control and command circuit for switching said switching element and selectively electrically connecting said external conductive plate to said first and second portions of conductor in response to a signal deriving from an electric vehicle passing over said external conductive plate;
wherein said supporting structure comprises;
a base which may be fixed to the ground by means of connection devices;
an upper block defining said upper surface and accommodating said electric connection means; and
fixing member fixing said upper block to said base.

Abstract
A ground power supply line for electric traction vehicles is provided with two conductors carried by a series of tiles aligned to one another; each tile has a conductive plate and a lower supporting structure, which is made of insulating material and accommodates electric connectors, normally open switches, and a control and command unit, which switches the switches for selectively electrically connecting the conductive plate to the conductors in response to a signal deriving from an electric traction vehicle passing over said external conductive plate; the upper surface of the conductive plates is flushed with the remaining part of a road surface.

14. A system for providing power to a motor vehicle traveling on a road bed, the motor vehicle including a first electricity captor and a second electricity captor, said electricity captors being arranged longitudinally with each other with respect to a direction of movement of the motor vehicle, the system comprising:
-
a row of tiles supported by the road bed, each tile including a top plate having an electrically conductive top surface, a body made of an electrically insulated material, said body supporting said top plate; and
an electrical circuit;a first electrical conductor extending along said row of tiles; a second electrical conductor extending along said row of tiles; and an electrical generator generating a voltage and having a first terminal of a first polarity and connected to said first electrical conductor and a second terminal having a second polarity and connected to said second electrical conductor; said tiles cooperating to activate switching circuits to selectively connect the top plate of a first tile to said first connector and simultaneously to connect the top plate of a second tile adjacent to said first tile to the second electrical connector when said motor vehicle is disposed above said first and said second tiles with said first electricity captor being in contact with the top plate of the first tile and the second electricity captor being in contact with the top plate of the second tile to thereby apply said voltage between said first and second electrical captors; wherein the body of each tile includes a first and a second channel, said tiles cooperating to hold said first and second electrical conductors in said first and second channels, respectively. - View Dependent Claims (15, 16, 17)
