摘要： An optical communication device comprising a horizontally rectangular main shelf, and a horizontally rectangular sub-shelf arranged in a vertically overlapping relationship with the first shelf. The main shelf and the sub-shelf have parallel guide rails in register with each other. Unit plates comprising optical modules for optical-electrical signal conversion are inserted in the main shelf in upright positions for engagement with the respective guide rails. Optical fiber supporting plates having means for supporting the optical fiber having a surplus length portion coiled in a freely extendable manner are inserted in the sub-shelf in upright positions for engagement with the respective guide rails. Accordingly, the surplus length portions of the optical fibers are orderly arranged in correspondence with the optical modules so as to prevent an incorrect connection between the optical fibers and the optical modules.

摘要： There is provided a circuit board cabinet which is capable of more reliably preventing flames of a fire in a shelf from spreading to external devices, without degrading cooling capability thereof. Flames of the fire occurring in the shelf rise within a slot, pass through a shield plate, and then enter a heat shield unit. In the heat shield unit, the flames are first blocked by a heat shield plate and substantially reduced in force while passing through holes formed through the heat shield plate. Portions of the flames which were not blocked by the heat shield plate reach a top board of the unit after passing through the holes, where they are reduced. Since there is a predetermined distance between the heat shield plate and the top board, the flames having passed through the heat shield plate spread horizontally to some extent and then reach the top board. Therefore, it is possible to reduce the force of the flames sufficiently by the top board. The flow of cooling air in normal use is sufficiently slower than that of flames, so that there is no fear of the existence of the heat shield unit causing a degraded heat dissipation.
摘要翻译：提供一种电路板机柜，其能够更可靠地防止搁板中的火焰蔓延到外部装置，而不降低其冷却能力。在货架内发生火灾的火焰在槽内升起，穿过屏蔽板，然后进入隔热罩。在隔热罩单元中，火焰首先被隔热板遮挡，并且通过穿过隔热板形成的孔时实质上减小。没有被隔热板遮挡的部分火焰穿过孔后到达设备的顶板，在那里它们被还原。由于在隔热板和顶板之间存在预定的距离，所以通过隔热板的火焰在一定程度上水平扩展，然后到达顶板。因此，可以通过顶板充分地减少火焰的力。正常使用中的冷却空气的流动比火焰的流动充分慢，所以不用担心热屏蔽单元的存在导致散热劣化。

摘要： A shelf-type telecommunications device has a back wired board assembly mounted on a back of a shelf unit into which a plurality of plug-in units are inserted side by side. The back wired board assembly has a main back wired board to which at least one plug-in unit is connected and a sub back wired board to which at least one external cable is connected, the outer surface of the main back wired board and the inner surface of the sub back wired board opposing each other. The main back wired board and the sub back wired board are fitted together by using a plurality of relay connectors or pin terminals so as to electrically connect the main back wired board and the sub back wired board to each other without the need for coaxial cables, thus reducing the size of the device.

摘要： A test connector for an electronic circuit unit to be mounted on a shelf (11) of an electronic apparatus, which is adapted to be inserted on the shelf only when a projection (33) on the electronic circuit unit comes into a matching position relative to a groove (25) provided on a frame portion (21) of the shelf (11). Guide members (51, 53) with guide grooves (55, 65) which guide the opposite side edges of the electronic circuit unit (27) are provided on a printed wiring board (45) which has connectors (47, 49) at the opposite ends thereof. A plurality of rod members (61, 63) are slidably located on the guide member (51). When mounting the electronic circuit unit, at least one of the rod members (61) or (63) is slid forwardly by the projection (33), prohibiting the placement of the test connector (43) on the shelf (11) unless a protruded end of the rod member (63) is in a matching position relative to the groove (25) on the shelf (11).
