Patent number: 9122021Abstract: The invention relates to a sealing enclosure and a sealing assembly comprising the sealing enclosure and a mating enclosure as well as a method to connect both. The sealing enclosure loosely receives a connector within a connector volume so that the connector, which may be of a standard type used in electronic or optic data transmission, may be displaced within a plug face at the forward end of the connector volume. Thus, the connector may compensate variations in the position of a mating connector with respect to the mating enclosure. Moreover, the sealing enclosure allows to seal off the connector volume and engage the sealing enclosure with a mating enclosure in a single motion. This is affected by having a cable seal interposed between an inner body and an outer body. If the outer body is moved forward to engage the mating connector, the cable seal is squeezed between the cable and the inner body sealing off the connector volume at the rearward end of the inner body.Type: GrantFiled: October 11, 2013Date of Patent: September 1, 2015Assignee: TE Connectivity Nederland B.V.Inventors: Jacob Arie Elenbaas, Jarno Verhoeven

Patent number: 8221006Abstract: A fiber optic cable assembly includes a fiber optic cable with one or more optical fibers attached to a housing. The housing includes a connector housing for a connector, a furcation housing for a furcation, and a splice housing for a mid-span cable splice. The furcation housing and the splice housing include a crimp body. The crimp body has a compression area and at least one hoop about the compression area defining a crimp zone. A crimp band is arranged for engaging the crimp zone and including an indentation defining a compression surface and a rib defining a rib interior. The crimp band and the crimp body cooperate to grip the strength element and resist cable pull off forces. A method of making the fiber optic cable assembly is also disclosed.Type: GrantFiled: August 23, 2010Date of Patent: July 17, 2012Assignee: Corning Cable Systems LLCInventor: Thomas Theuerkorn

Patent number: 8152384Abstract: Push-pull fiber optic connectors and cable assemblies having a latch that is actuated by a cam surface are disclosed. The fiber optic connectors include a ferrule and a housing having the latch. A shroud fits over a portion of the housing and allows the craft to grab the shroud and push the shroud and hence the fiber optic connector into a suitable adapter or the like. Likewise, the craft can grab the shroud and pull on the same to remove the fiber optic connector out of the adapter or the like. The cam surface is disposed on a decoupling member, wherein the decoupling member is attached to the shroud so the components can move together. Methods of making the push-pull fiber optic connector are also disclosed.Type: GrantFiled: October 15, 2009Date of Patent: April 10, 2012Assignee: Corning Cable Systems LLCInventors: Michael de Jong, Paul X. Devereaux, Ashley W. Jones, Ronald L. Mudd

Patent number: 8047726Abstract: An optical connector in which the housing property into a cabinet or the like can be enhanced because of the compactification, and which can solve problems of the increase of the bending loss of an optical fiber, the breakage, and the like is obtained. In an optical connector which houses and holds a fusion spliced portion where a short optical fiber previously fitted to an optical connector ferrule is fusion-spliced with a coated optical fiber, one end of a protection sleeve which armors the fusion spliced portion is coupled to the optical connector ferrule. As a result, the length of the protection sleeve which covers the fusion spliced portion so that the fusion spliced portion is positioned at the middle can be set with reference to an end portion of the optical connector ferrule. Therefore, the protection sleeve can be shortened, and compactification of the optical connector can be realized.Type: GrantFiled: November 13, 2007Date of Patent: November 1, 2011Assignee: Sumitomo Electric Industries, Ltd.Inventors: Yoshikyo Tamekuni, Yukihiro Yokomachi, Tsutomu Watanabe, Toshihiko Honma, Masahiro Shibata
