Abstract
A substrate unit includes a conductive case, an insulating case arranged in the conductive case, a first screw member having conductivity, arranged in the conductive case and fixing the insulating case to an inner wall surface of the conductive case, a circuit substrate provided opposite to the inner wall surface with respect to the insulating case and fixed to the insulating case, and a second screw member having conductivity and fixing the circuit substrate to the insulating case. The first screw member and the second screw member are screwed in toward the inner wall surface. The first screw member and the second screw member are spaced from each other. The first screw member and the second screw member are connected to each other with a connecting member having conductivity.
Claims6
A substrate unit comprising:
- a conductive case having conductivity;
- an insulating case arranged in said conductive case;
- a first screw member having conductivity, arranged in said conductive case and fixing said insulating case to an inner wall surface of said conductive case;
- a circuit substrate provided opposite to said inner wall surface with respect to said insulating case and fixed to said insulating case;
- and
- a second screw member having conductivity and fixing said circuit substrate to said insulating case,
- said first screw member and said second screw member being screwed in toward said inner wall surface, when said first screw member and said second screw member are seen from a position away from said inner wall surface in a direction that said inner wall surface and said insulating case are arranged, said first screw member and said second screw member being spaced from each other, and
- said first screw member and said second screw member being connected to each other with a connecting member having conductivity.
