Abstract

PROBLEM TO BE SOLVED: To facilitate work of inserting into and extracting from the inside of electronic equipment, by combining an inner side housing having a contact piece contacting the terminal part of a printed wiring board, and an outer side housing having a terminal portion contacting the contact piece. SOLUTION: A printed wiring board 10 is inserted into an inner side housing 5 while being pushed against it, the terminal part 12 of the housing 5, having elasticity by the guiding part 11 of an outer side housing 9, is made into a condition where the terminal part 12 is being closed, the terminal 13 of the wiring board 10 and terminals 2 are contacted gradually, and the terminal part 12 of the housing 5 and the wiring board 10 are contacted by the guiding part 11 of the housing 9 to be housed in the housing 9 to contact a terminal 3 and the terminal 7 of the housing 5. The housing 5 is pushed up in an upper part direction by a spring 6 to be fixedly retained by a cam 4 whose rotation angle is regulated by the protruded part 8 of the housing 9.
