Abstract
A printed circuit board assembly is disclosed. The printed circuit board assembly includes a printed circuit board, a sensor mounted on one side of the printed circuit board to detect a magnetic field, and a bus bar disposed in contact with another side of the printed circuit board, wherein a thickness between a region of the another side of the printed circuit board, with which the bus bar is in contact, and the one side of the printed circuit board is smaller than a thickness between a remaining region of the another side of the printed circuit board and the one side of the printed circuit board.
Claims16
A printed circuit board assembly comprising:
- a printed circuit board;
- a bus bar disposed in contact with a front side of the printed circuit board;
- a sensor mounted on a rear side of the printed circuit board, the sensor being configured to detect a magnetic field;
- a shield disposed around at least a portion of the bus bar;
- and
- a holding member disposed in contact with the shield,
- wherein the printed circuit board comprises a plurality of first through holes and a second through hole penetrating from the front side to the rear side,
- wherein the bus bar comprises:
- a longitudinal part disposed in contact with both the front side of the printed circuit board and the shield;
- and
- a connection part disposed in contact with the longitudinal part and fitted into the second through hole in a direction toward the rear side from the front side of the printed circuit board,
- wherein at least a part of the shield is fitted into holes of the plurality of first through holes in the direction toward the rear side from the front side of the printed circuit board so that a rear side of the shield is disposed in contact with the longitudinal part, and
- wherein the holding member comprises a top holding part disposed in contact with a front side of the shield.
