Tube-type Holding Structure Patents (Class 385/66)
  • Patent number: 5121455
    Abstract: A fiber optic connector for terminating a length of fiber optic cable having a central fiber optic core covered by cladding. The connector preferably comprises a rigid, one-piece, integrally molded plastic sleeve for fitting over the end of the optic cable with an outermost end of said cable being typically stripped of all material outside of said cladding, and said outermost end projecting in snugly fitting relation through a bore in an outer end of the rigid sleeve. The bore also defines through the sleeve a section spaced from the outer end which is of increased diameter when compared with the bore at the outer end, to snugly receive a portion of the fiber optic cable having unstripped buffer. The rigid sleeve may carry side apertures for receiving a plurality of U-shaped retention members which pass transversely through the side apertures, preferably from a plurality of transverse directions, to grip and retain the fiber optic cable.

  • Patent number: 5091987
    Abstract: A fiber optic transmission line is passed uninterrupted through a hermetically sealed dielectric pressure barrier. This is accomplished by fusing glass or casting a resin about hollow upstanding sleeves within the bore of a connector housing. The glass forms a strong hermetically sealed barrier caused by strong compressive forces resulting from the different coefficients of thermal expansion between the metal bore walls and glass matrix. A fiber optic core is passed through a hollow sleeve and sealed to an aperture in a contact pin which is hermetically sealed to the end of the sleeve. The end of the pin is polished to provide an abutment joint with a corresponding contact surface on an associated connector. In the case of a resin matrix, the resin may be cast about the sleeves within the housing bore. During hardening, the resin will bond to the sleeves and walls of the bore to form a strong hermetically sealed pressure barrier.

  • Patent number: 5091990
    Abstract: A fiber-optic connector for a cable with an optical fiber. The connector includes a first backpost having an exteriorly threaded forward portion, a rearward portion attachable to the cable, and a central passageway extending therethrough. The connector further has a body with a forward end portion, an interiorly threaded rearward end portion, and a central passageway extending therethrough. The body threads have a pitch diameter and pitch thread which mate with the threads of the first backpost. A second backpost is positioned within the body central passageway, and has a forward end portion which holds a ferrule in position, and a rearward end portion which extends through a rearward opening in the body and into a forward opening of the first backpost.
