Spacers specific not montees floating on printed circuit with spacers hollow gripping two caps blinds art, making it possible to stack the modules with screw

摘要

The assembly has non-encrusted hollow threaded upper spacers (15) and lower nut rings (22) freely mounted on two printed circuit boards (10, 11) with hollow spacers (24) and special nut locking two cover caps (8, 9), which permit screwing of electronic modules (5) connected to each other by a screw (28). The screw traverses the hollow spacers and the nut rings. The upper spacers have spigots (14G1, 15G1) and lateral holes (16X1) mounted on an upper side of the boards.
