Mounting structure for a printed board
Abstract
Abstract A mounting structure for a printed circuit board comprises a rack frame having guide rails to receive the circuit board. The circuit board is retained in fixed position in the rack frame by a leaf spring which is flexibly mounted on the circuit board and has a detent portion engageable in a recess in the rack frame. A rod member mounted on the circuit by means of a bracket is engageable with the leaf spring and is operable to flex the leaf spring between a position in which the detent portion is engaged in the recess of the rack frame to secure the circuit board in position in the rack frame and a position in which the detent portion of the leaf spring is disengaged from the recess so as to release the circuit board for removal from the rack frame. In one form the rod member is rotatable and has a flat portion which is engageable by the leaf spring to disengage the detent portion from the recess. In other forms, the rod member is movable is a lengthwise direction and has a thicker portion and a thinner portion which are alternatively engageable with the leaf spring so as to bring the detent portion into engagement with or to disengage it from the recess in the rack frame.
