Printed circuit board module

摘要

A printed circuit board module consists of a first printed circuit board with a nonconductive panel connected to the foil side of the board. Extending parallel to and spaced from the first printed circuit board is a frame having a number of standoffs connected to the first printed circuit board and its insulating panel. A frame insert consisting of a nonconductive panel to which a second printed circuit board is fastened is removably positioned within the central opening of the frame. Two opposed inner edges of the frame have two sets of spaced support tabs. The two sets of tabs are parallel to one another and staggered so as to form a channel therebetween. The corresponding edges of the frame insert have a plurality of aligned locking tabs so dimensioned and positioned as to fit between adjacent locking tabs in one set and slide along the channel to retain the insert within the frame. An additional locking mechanism is provided to prevent the frame insert so retained from sliding along the channel into the position at which it may be released from the frame.
