Abstract
A circuit board having: a through hole to mount the circuit board to a casing or an electronic apparatus; and a coil-shaped conductive pattern provided on a plane perpendicular to the through hole so as to intersect a circumference around the through hole as a center.
Claims20
A circuit board comprising:
- a through hole provided in said circuit board and located to permit a connector to be inserted in said through hole to mount said circuit board to a casing or an electronic apparatus;
- and
- a coil-shaped conductive pattern to permit measuring current flowing through said connector, said coil-shaped conductive pattern being provided on a plane extending along a longitudinal axis of the through hole, said plane extending through a center of the through hole located on said longitudinal axis to thereby intersect with a circumference of said through hole.
A circuit board comprising:
- a through hole provided in said circuit board and located to permit a conductive junction part to be inserted in said through hole to mount said circuit board to a casing or an electronic apparatus;
- and
- a conductive pattern formed around said through hole in said circuit board,
- wherein said conductive pattern is a coil-shaped conductive pattern located in such a manner relative to said through hole that when a conductive junction part is mounted in said through hole, said conductive pattern intersects a magnetic flux of a magnetic field which is caused by a current flowing in said junction part to permit measuring said current.
