<p>The circuit housing is basically rectangle and has guide ribs (7) arranged in pairs at the side walls (3), between which, in a vertical direction to the base, circuit boards can be slotted in and held firmly. In addition, wider, bracket shaped-guide ribs (9) are formed on the inner surface of the side walls (3), having moulded nuts for fixing the cover. For guiding and retaining circuit boards (6), adaptor walls (10) are fixed to the side walls (3),having two support ribs (11) running parallel to the guide ribs (9), and guide grooves (12) for easy introduction of the board (6). The housing is able to accept circuit boards of various dimensions, without being complicated in construction, and is cost saving to produce.</p> |
