摘要

The slide-in unit has a front plate (4) provided with two parts (12,18) on its inside each having a guide slot (13) with a projection (16). The circuit board (11) slides along the guide slots and is locked in place by recesses (17) set into its long edges. (The projection engage these recesses). One (12) of the two parts also contains the hole (3) for the bolt that locks the slide-in unit into its rack. The locking bolt is inserted from the rear of the front plate (4) and locked in an axial direction behind a spring flap (7) projecting from the said part (12). The advantage lies in cheapness and in rapid assembly.
