Electronic circuit unit capable of external connection

摘要

An electronic circuit unit includes a circuit board (10) with conductors for connection (14) on an edge (12), a case (20) for housing the circuit board (10) and a connector (C). The case (20) includes an opening (21) that allows the circuit board (10) to be inserted in a board inserting direction and holds the circuit board (10) at a specific board holding position. The connector (C) includes connector terminals (30) to be mounted on ends of wires (W), and a housing (40) for holding the connector terminals (30) so that the connector terminals (30) can simultaneously contact the conductors for connection (14). The housing (40) includes a lid (48) for closing the opening (21). The case (20) locks the housing (40) at a position where the connector terminals (30) contact the conductors for connection (14) of the circuit board (10) at the board holding position.

主权项

1. An electronic circuit unit, comprising:
a circuit board including an edge part and first and second opposite surfaces extending from the edge part, a plurality of first conductors for connection provided on the first surface thereof and a plurality of second conductors for connection provided on the second surface thereof; a case for housing the circuit board; and a connector for connecting wires to the conductors for connection of the circuit board; wherein: the case includes an opening that is open in a specific direction and is so shaped that the circuit board is insertable into the case in a board inserting direction perpendicular to a plate thickness direction of the circuit board through the opening with the edge part in the lead; the connector includes a board insertion space configured for receiving the edge part of the circuit board therein, first and second pluralities of terminal accommodating chambers disposed respectively on first and second sides of the board insertion space, first and second pluralities of connector terminals connected to ends of the respective wires and disposed respectively in the first and second terminal accommodating chambers, the first and second pluralities of connector terminals being electrically conductively connectable respectively to the first and second pluralities of conductors for connection of the circuit board by respectively coming into contact with the conductors, the housing being configured for holding the connector terminals in such an arrangement that the respective connector terminals simultaneously come into contact with the respective conductors for connection, the housing being shaped to be mountable into the case to close the opening of the case at a position where each connector terminal held in the housing comes into contact with each conductor for connection of the circuit board at a board holding position; and the case includes a housing locking portion for locking the housing of the connector at the position where each connector terminal of the connector comes into contact with each conductor for connection of the circuit board housed in the case.
