    • A rack-mounted assembly (10) comprises one or more racks, each capable of containing one or more printed circuit boards (PCB) (18), interconnected by a backplane (15) which is located along the bottom of a shelf (14). This position of the backplane (15) allows the rear wall of the rack-mounted assembly to be perforated, thereby permitting a cooling airflow for the PCBs to pass in through the front of the assembly and then out through the back. An insertion mechanism is provided to allow a PCB to be inserted into a rack. To achieve this, the PCB must first travel backwards into the rack-mounted assembly, and then downwards into engagement with the backplane (15). In one embodiment, this is accomplished by supporting the PCB from a hanger (100) which moves in and out of the rack-mounted assembly along a guide rail (45). The hanger includes slots (115) that retain pins (110) from the PCB. The slots are orientated diagonally upwards and backwards. A compression spring (60) is also provided to urge the pins (and hence PCB) forwards. Upon insertion, the hanger moves along guide rail (45) until the PCB abuts a stop (50). At this point further insertion of the hanger forces the pins (110) to move along slots (115) in opposition to spring (60), thereby driving the PCB down into engagement with the backplane (15).
    • 机架安装组件(10)包括一个或多个机架,每个机架能够容纳通过沿着架子(14)的底部定位的背板(15)互连的一个或多个印刷电路板(PCB)(18) 。 背板(15)的该位置允许机架安装组件的后壁穿孔,从而允许PCB的冷却气流通过组件的前部通过,然后穿过背部。 提供插入机构以允许PCB插入机架中。 为了实现这一点,PCB必须首先向后移动到机架安装的组件中,然后向下移动以与背板(15)接合。 在一个实施例中,这是通过从沿着导轨(45)进出机架安装组件的衣架(100)支撑PCB来实现的。 衣架包括从PCB保持销(110)的槽(115)。 槽向上和向后倾斜定向。 还提供压缩弹簧(60)以将销(以及因此PCB)向前推动。 插入时,吊架沿着导轨(45)移动,直到PCB邻接止动件(50)。 在这一点上,衣架的进一步插入迫使销(110)相对于弹簧(60)沿狭槽115移动,从而将PCB向下驱动以与背板(15)接合。
