<p>The front plugs are coded according to their mounting positions. Each circuit board (3) has a coding bar (10) on the front side of a plate-shaped support (9) in the subassembly frame. It is provided with coding elements (16, 17) cooperating with coding elements of the corresponding front plug. The support (9) has on its short sides reinforcing ribs (11), and spring locking devices (12, 13) on its long sides. When the support (9) is inserted into the subassembly frame, they lock in recesses in holding strips (1, 2) for guiding bars (4, 5) for the circuit boards. They also hold the support (9) parallel to the corresponding circuit board.</p> |
