STRUCTURE FOR CONNECTING CONNECTOR TO CIRCUIT SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To reduce deviations between a circuit board and a terminal pin due to the difference in thermal expansions amounts and to stabilize a resistance in a connector connecting structure, in which a connector is electrically connected to the circuit board by bringing the end of the terminal pin having elasticity and extending from the connector into press-contact with the circuit board. SOLUTION: A terminal pin made of an elastic member is supported by and fixed to a connector 3 at one end and is brought into conductive contact with a circuit board 4 at the other end in an elastic force acting state. The circuit board 4 is fixed via a fixing member 6 at a board fixing portion 5. A supporting portion 1a and a contact portion 1b of the terminal pin and the board fixing portion 5 are aligned on one and the same line H perpendicular with respect to the circuit board 4.
