ELECTRICAL JUNCTION BOX

摘要

An electrical junction box is provided in which a printed circuit board is accommodated in a case so as to configure an internal circuit, the electrical junction box achieving downsizing/densification with high space efficiency and simplified routing of electric cables of connectors. As the internal circuit, a printed circuit board stack is used in which a first printed circuit board and a second printed circuit board are arranged so as to face each other. A power supply input connector that is to be mounted to a front wall-side connector mounting portion provided on a front wall of a case is connectable to the first printed circuit board, whereas an output connector that is to be mounted to a rear wall-side connector mounting portion provided on a rear wall of the case is connectable to the second printed circuit board.

主权项

1. An electrical junction box comprising:
printed circuit boards accommodated in a case so as to configure an internal circuit, the internal circuit including a printed circuit board stack in which respective printed wirings of a first printed circuit board and a second printed circuit board are electrically connected to each other via an inter-board connection terminal, the first printed circuit board and the second printed circuit board being arranged so as to face each other across a gap, wherein the case has a front wall and a rear wall that are arranged so as to face the printed circuit board stack from both sides in a direction in which the first printed circuit board and the second printed circuit board face each other, and wherein a power supply input connector mounted to a front wall-side connector mounting portion provided on the front wall of the case is connectable to the first printed circuit board, whereas an output connector that is to be mounted to a rear wall-side connector mounting portion provided on the rear wall of the case is connectable to the second printed circuit board.
