Claim of US Patent No. 10,251,294

1. A power supply structure comprising:a first plate member that includes a load, and has first wiring connected to the load;
a second plate member that includes a power supply unit that supplies electric power to the load and has second wiring connected to the power supply unit; and
a block member that has prism-shaped conductive members arranged with a gap interposed therebetween and fixed, is held between the first plate member and the second plate member such that end faces of the conductive members are in contact with the first plate member and the second plate member, and consists of power feed blocks and GND blocks being arranged alternately, the power feed blocks being connected to the first wiring and the second wiring such that current flows from the second plate member to the first plate member, the GND blocks being connected to the first wiring and the second wiring such that current flows from the second plate member to the first plate member;
wherein in the block member, the conductive member through which current flows in the direction from the second plate member to the first plate member has one end face connected to an electrode on the second plate member connecting to the second wiring and has another end face connected to an electrode on the first plate member connecting to the first wiring connected to an input terminal of the load, and the conductive member through which current flows in the direction from the first plate member to the second plate member has one end face connected to an electrode on the first plate member connecting to the first wiring connected to an output terminal of the load and has another end face connected to a terminal on the second plate member connecting to the second wiring connected to ground.
