ELECTRICAL CONNECTION STRUCTURE OF SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To conduct electrical connection of an external circuit for a circuit substrate in the structure with less number of components. SOLUTION: In a structure for electrically connecting a connector C connected to the other circuits to a circuit substrate P2, a hole 6 is provided on the circuit substrate P2, and a connection conductor 4 is provided on the internal surface of the hole for electrical connection with a circuit on the circuit substrate. The connector C is provided with a housing 20 in a shape which can be engaged with the internal side of the hole 6 and a terminal 10 which is held with the housing 20 and includes a contact portion 12b which is partly exposed from the external surface. The contact portion 12b is placed in contact with the connection conductor 4 under the condition that the housing 20 is engaged with the hole 6.
