Patent number: 6556762Abstract: A cable management bar and bracket assembly is mounted within an equipment enclosure. The brackets are supported on and movable along the bar to present cable support positions at various transverse locations. The brackets are of generally U-shaped configuration with cable supporting hooks formed in one depending flange and with inwardly projecting tabs formed in the other depending flange which extend beneath the bar to make the bracket captive on the bar. Slots formed in the bar at one axial location permit the bracket to be assembled to and removed from the bar when the tabs are aligned with and passed through the slots. The assembly also includes mounting brackets at each end of the bar which are formed integral with the bar of a single piece of material while the bar portion is formed as a downwardly opening U-shaped channel element.Type: GrantFiled: December 13, 2001Date of Patent: April 29, 2003Assignee: International Business Machines CorporationInventors: Ricky Dean Erickson, David George Lund, Aleksander Miroslaw Mustwillo, Christopher Lee Tuma

Patent number: 6545222Abstract: A cable and a cable stripping method which facilities the stripping of an intermediate part of a cable having a cable core covered by a plastic sheath provided around the outer periphery without damaging the cable core. In a cable having a plastic sheath 2 on a cable core 1, either a groove 2a is provided in the inner surface of the plastic sheath 2 extending in the longitudinal direction of the cable. A ripcord 3 is either fitted in the groove 2a or adhered to the inner surface of the plastic sheath. In either case, the position-indicating means 2b showing the position of the ripcord is provided on the outer surface of the plastic sheath 2 at the point where the ripcord 3 is fitted.Type: GrantFiled: January 9, 2001Date of Patent: April 8, 2003Assignees: Sumitomo Electric Industries, Ltd., Nippon Telegraph and Telephone CorporationInventors: Tomoyuki Yokokawa, Yoshiyuki Suetsugu, Masahiro Eguchi, Kiyotaka Nishioka, Kazuo Hogari, Hideyuki Iwata

Patent number: 6359228Abstract: A closure arrangement for cable splice assemblies having two hinged cover members. The cover members are independently hingedly secured to a central spine. The spine, in turn, is affixed to a portion of the frame of the splice assembly. In operation, the cover members are opened outwardly to expose virtually all of the outer portion of the internal splice components. In the described embodiment, the cover members are secured to one another by clasp or buckle-type closures that engage complimentary tabs.Type: GrantFiled: January 31, 2000Date of Patent: March 19, 2002Assignee: Corning Cable Systems LLCInventors: Kevin L. Strause, Kelly J. Smith, Christopher L. Holderness

Patent number: 6337438Abstract: A casing structure for a communication equipment in which panels mounted in the casing are electrically insulated from a messenger wire. When the casing of the communication equipment is mounted on the messenger wire, the insulation prohibits impediments otherwise caused by extraneous noise current flowing in the messenger wire. The mounting portion of the case has a handle structure which provides improved operability and convenience.Type: GrantFiled: November 10, 1997Date of Patent: January 8, 2002Assignee: NEC CorporationInventor: Takashi Oyamada

Patent number: 6284972Abstract: A distributor including a plurality of connection points interconnected by jumpers. The distributor further includes: cable terminations each of which is provided with a plurality of connection strips, each strip being designed to receive one or more connector elements constituting the connection points; a central hub; and around the central hub, fixing means for individually connecting the cable terminations, where the cable terminations and the fixing means are organized so that the connections strips of each cable termination are disposed radially relative to the hub when the cable termination is put into place, and so that all of the jumpers can present substantially the same length and can pass from one connection point to another connection point by begin laid in part over the hub.Type: GrantFiled: March 9, 2000Date of Patent: September 4, 2001Assignee: PropticInventors: Michel L. Dillat, Pierre J. Bouvier

Patent number: 6204445Abstract: A communications cable is provided having a support strand and at least one coaxial cable helically wound around the support strand. The coaxial cable includes an inner conductor, a dielectric surrounding the inner conductor, an outer tubular metallic sheath surrounding the dielectric, and optionally a protective jacket surrounding the metallic sheath. The communications cable is manufactured such that the ratio of the length of coaxial cable to the length of support strand is between about 1.005 and 1.015. The communications cable is also preferably wound around the support strand using a varying lay length thereby minimizing signal loss due to cable damage. The communications cable of the invention is especially suitable for aerial installation and may be installed in one pass, without the need to form expansion loops in the coaxial cable.Type: GrantFiled: February 5, 1998Date of Patent: March 20, 2001Assignee: CommScope Properties, LLCInventors: Michael Damon Gialenios, David Jonathan Irvin, Andy Bryant, Jr.
