Abstract

The invention relates to a power supply assembly intended to recharge electric batteries for several vehicles introducing a plurality of electricity transmission devices (1A, 2A) intended to be placed on the ground with a conductive arrangement (1B, 2B) positioned in said electricity transmission device and including at least one post supporting a power supply terminal and positioned on said electricity transmission devices. According to the invention—each said electricity transmission device is made up of a set of conductive strips (1B, 2B) coated in a bar of an electrically insulating material—at each of those ends, said bar has a perpendicular extension (1C, 1D, 2C, 2D) at the end of which said conductive strips (1B, 2B) are accessible, said bar and its said extensions forming a U-shaped structure whereof the substantially horizontal bar is the base provided with arrangements for fastening to the floor and the substantially vertical extensions are the branches,—said conductive strips are accessible at the free end of said extensions,—each power supply device is adjacent to at least one other power supply device and said adjacent perpendicular extensions of these power supply devices are electrically connected to each other and to a corresponding shared power supply terminal.

Claims

1. A power supply assembly for recharging electric batteries for several electric motor vehicles comprising:

a plurality of electricity transmission devices for placing on the floor;

a conductive arrangement disposed in said electricity transmission device and including at least one post supporting a power supply terminal and disposed on said electricity transmission devices, wherein;

each said electricity transmission device is formed by a set of conductive strips coated in a bar of electrically insulating material,

said bar has, at each of these ends, a perpendicular extension at the end of which said conductive strips are accessible, said bar and its said extensions forming a U-shaped structure of which the substantially horizontal bar is the base provided with arrangements for fastening to the floor and the substantially vertical extensions are the branches,

said conductive strips are accessible at the free end of said extensions,

each power supply device is adjacent to at least one other power supply device and said adjacent perpendicular extensions of these power supply devices are electrically connected to each other and to a corresponding shared power supply terminal.

2. The assembly as claimed in the preceding claim, wherein said adjacent perpendicular extensions are covered by said post arranged atop said extensions and disposed below said terminal.

4. The assembly as claimed in claim 1, wherein said bar has a length between 2 and 3 meters.

5. The assembly as claimed in claim 1, wherein a longitudinal neutral strip and/or ground strip (C_N, C_T) coated in said bar covers said longitudinal phase strips (C₁ to C₃).

6. The assembly as claimed in claim 1, wherein at least one of said perpendicular extensions has a straight cylindrical cavity (2F′

).

7. The assembly as claimed in claim 1, wherein at least one of said perpendicular extensions has a straight cylinder (1F′

).

8. The assembly as claimed in claim 6, wherein the radius of said cylinder and of said cavity is identical.

9. The assembly as claimed in claim 6, wherein two of said perpendicular extensions having a straight cylindrical cavity are assembled with each other by way of a tubular element of the same radius, encased in each of said straight cylindrical cavities.

3. The assembly as claimed in claim, wherein said bar is trapezoidal in section, its greatest face (S) being intended to be disposed on the floor or equivalent,
