  • Publication number: 20150333303
    Abstract: This rack structure includes: a battery shelf (55) for accommodating a plurality of battery units (30); a rack (10) in which at least one battery shelf (55) is mounted; and a connector (180) which electrically connects the battery shelf and the rack with each other. The connector (180) has a first connector member (181) disposed on a rear surface of the battery shelf and a second connector member (191) disposed on the rack side, and is configured such that the first connector member (181) and the second connector member (191) are connected with each other while the battery shelf (55) is moved to a predetermined mounting position in the rack.

  • Publication number: 20150303419
    Abstract: A battery shelf assembly (50) includes: a plurality of battery units (30); a battery shelf (55) accommodating the battery units (30), configured such that the battery units (30) are mounted or dismounted by sliding movement in the battery shelf; and a power connector (120) connecting the battery unit (30) and the battery shelf (55) so that power of the battery unit can be output. The power connector (120) has: a first connector member (121) disposed at an electrode terminal of the battery unit (30); a second connector member (131) disposed on the battery shelf side and configured to connect with the first connector member (121); and a floating structure that absorbs a position gap between the first and second connector members.

  • Patent number: 6222977
    Abstract: A structure for introducing an optical cable into a communication apparatus includes an adapter (3) to be affixed to a side wall (21) forming a part of the casing (2) of the apparatus. A case (4) is fitted in a bore axially extending throughout the center of the adapter (3). A ring nut assembly (5) holds an optical cable (6) at its center and is connected to the adapter (3) in such a manner as to cover the case (4). The cable (6) includes a tension merber (61) introduced into the casing (2) via the case (4) and adapter (3) and affixed by a tension member affixing portion (46) disposed in the casing (2). In this condition, the cable (6) is firmly affixed by the ring nut assembly (5) and tension member affixing portion (46), i.e., at two points. The fibers of the cable (6) are therefore free from breakage ascribable to a twisting force or a pulling force.

  • Patent number: 6023602
    Abstract: A coaxial repeater of the present invention includes a connector having an L shaped metal piece 1 and an insulating casing 2. The connector is mounted in an introducing hole 3a-1 provided in a casing 3. A connecting portion 8a of an amplifier portion 8 is electrically connected to one of protrusions of the connector and a center conductor 4a-1 of an adapter 4-1 is fitted in and electrically connected to the other protrusion of the connector. The introducing hole 3a-1 becomes a space 3g-1 when the adapter 4a-1 and the amplifier portion 8 are mounted. The space 3g-1 is shielded from a receiving space 3b of the casing 3. With the coaxial repeater constructed as mentioned above, it is possible to improve electrical characteristics of a device operating in a high frequency band, facilitate the maintenance thereof, reduce the number of parts thereof and reduce the cost of parts.
