Publication number: 20200373700Abstract: A connector For wires to be connected in harsh environment applications. This approach uses low pressure casting techniques. An alternative embodiment uses a thin, rigid stabilizer to position one or more contacts inside of the connector shell. Foamed polyurethane is injected inside the connector shell in liquid form. This encapsulates the stabilizer (when used) and forms an insulator around the contacts and wires. The polyurethane is bonded to the inside of the connector shell. The bonding strength of the polyurethane will form an environmental seal suitable for harsh environmental applications. In some cases a primer may be pre-applied to the inside of the connector shell the contacts, the wires, or the stabilizer to enhance the bonding of the polyurethane.Type: ApplicationFiled: May 24, 2019Publication date: November 26, 2020Applicant: ISC ENGINEERING, LLCInventors: Steven Lee WILLING, Harald Markus GIEBEL, Matthew Jay DUFFIELD, Ryan Timothy JENNER, Tyler James GOODEN

Patent number: 6931193Abstract: Methods are provided for validating the continuity of one or more optical fibers upon which a fiber optic connector is mounted. Typically, the fiber optic connector is mounted upon an optical field fiber by actuating a cam mechanism to secure the optical field fiber in position relative to an optical fiber stub. If subsequent testing indicates that the continuity of the optical field fiber and the optical fiber stub is unacceptable, the cam mechanism can be deactuated, the optical field fiber can be repositioned and the cam mechanism can be reactuated without having to remove and replace the fiber optic connector.Type: GrantFiled: September 13, 2004Date of Patent: August 16, 2005Assignee: Corning Cable Systems LLCInventors: Brandon A. Barnes, Thomas A. Church, Michael de Jong, Markus A. Giebel, Sean M. Kerr

Patent number: 6634796Abstract: Devices and methods are described that permit simple correction of a fiber optic polarity reversal problem. An adapter is described having receptacles to receive a connector on a first end, or user end, and on a second end, or contractor end. Both the receptacles provide keying arrangements so that the connectors can be received only when correctly oriented with respect to the adapter. The keying arrangement on the contractor end, however, is reversable so that the connector may be inserted in one of two predetermined orientations, at the behest of the contractor or installer. Adapters are also described that receive connectors only in a physically reversed orientation to counteract a reverse polarity condition. In addition, a jumper is described that can be interposed between a connector and adapter to correct a reverse polarity condition.Type: GrantFiled: June 30, 1999Date of Patent: October 21, 2003Assignee: Corning Cable Systems LLCInventors: Michael de Jong, Markus A. Giebel, Thomas A. Church, Kevin L. Morgan, James P. Luther

Patent number: 6547449Abstract: A preassembled multifiber connector is provided that includes a connector housing and a windowless multifiber ferrule that is substantially rectangular in lateral cross-section. The windowless multifiber ferrule can be at least partially disposed within an internal cavity defined by the connector housing to thereby form a multifiber connector that is free of optical fibers. Thus, the multifiber connector is capable of being preassembled prior to inserting the plurality of optical fibers into the optical fiber bores defined by the windowless multifiber ferrule. A corresponding method of preassembling a multifiber connector is therefore also provided according to the present invention. A ferrule is also provided that is capable of being selectively converted from a windowless configuration to a windowed configuration. The ferrule of this embodiment includes a ferrule body that not only defines at least one optical fiber bore, but that also defines a well extending through a side surface of the ferrule body.Type: GrantFiled: December 17, 1999Date of Patent: April 15, 2003Assignee: Corning Cable Systems LLCInventors: David L.

Patent number: 6457874Abstract: A mixed media outlet is provided that is capable of being mounted upon a wall and that includes ports that are typically designed to provide separate access to an electrical network and to an optical network. The wall mounted outlet can therefore permit a telephone to be connected to the electrical network, and a computer to be connected to the optical network. Alternatively, the outlet can permit a telephone to also be connected to either the same or a different optical network than the computer. The mixed media outlet includes a housing adapted to be wall mounted and first and second ports that are disposed within openings defined by the housing, such as a data port and a voice port.Type: GrantFiled: August 31, 2000Date of Patent: October 1, 2002Assignee: Corning Cable Systems LLCInventors: Donnie R.

Patent number: 6439780Abstract: A fiber optic cable connector for an optical ribbon comprises a multi-fiber ferrule having a plurality of stub fibers secured therein with ends of the fibers projecting beyond the end of the ferrule. The connector also includes first and second opposed splice members extending lengthwise from a first end proximate the end of the ferrule to an opposite second end, and the ends of the stub fibers extend between the opposed splice members at the first end thereof and are disposed in fiber-aligning grooves formed in the first splice member. The splice members are arranged with a fiber-receiving space therebetween to allow the optical fibers of the fiber optic ribbon to be inserted through the fiber-receiving space such that the optical fibers engage the grooves and are guided by the grooves into optically connected relation with the ends of the stub fibers.Type: GrantFiled: August 31, 2000Date of Patent: August 27, 2002Assignee: Corning Cable Systems LLCInventors: Ronald L.

Patent number: 6396993Abstract: The challenge of pulling an optical fiber having a connector at its terminal end without incurring damage to the fiber or connector due to excessive pulling or bending is met by introducing a breakaway feature that disconnects the connectorized fiber from the pulling mechanism upon detecting excessive force. The breakaway feature may be positioned at several locations along the pathway connecting the optical fiber and the pulling force. In one embodiment the breakaway feature is disposed on a cover over the connectorized front end of the optical fiber. In other embodiments the breakaway element is inserted along the cord connecting the connectorized optical fiber to the pulling force.Type: GrantFiled: December 30, 1999Date of Patent: May 28, 2002Assignee: Corning Cable Systems LLCInventors: Markus A.

Patent number: 6350062Abstract: A multifiber ferrule is provided that includes a ferrule body that defines at least one elongate hole opening through the front face of the ferrule body that, in turn, includes a lead-in portion proximate the front face for guiding the respective alignment member into the elongate hole. The ferrule body at least partially defines one or more elongate holes, such as a guide pin hole or an alignment groove, each having a longitudinal axis extending therethrough. Each elongate hole includes the lead-in portion proximate the front face and an adjacent alignment portion. The lead-in portion expands radially outward from the longitudinal axis in a direction extending from the adjacent alignment portion to the front face of the ferrule body. As such, the opening of the lead-in portion through the front face of the ferrule body is larger in lateral cross-section than the opening of the lead-in portion into the adjacent alignment portion.Type: GrantFiled: May 7, 1999Date of Patent: February 26, 2002Assignee: Corning Cable Systems LLCInventors: Dennis M.

Patent number: 6149313Abstract: A gender selectable fiber optic connector is provided which can be readily converted between male and female configurations following assembly and polishing of the connector. The gender selectable fiber optic connector includes a housing, a ferrule operably connected to the housing such that a forward portion of the ferrule extends beyond the housing, and a shroud adapted to be mounted upon the forward portion of the ferrule such that the forward portion of the ferrule extends through a passageway defined by the shroud. In order to alter the gender of the fiber optic connector, the shroud has both male and female configurations. In this regard, the male configuration of the shroud includes at least one guide pin extending lengthwise through the passageway defined by the shroud for engaging a lengthwise extending alignment groove defined by the ferrule in order to produce a male fiber optic connector.Type: GrantFiled: December 31, 1998Date of Patent: November 21, 2000Assignee: Siecor Operations, LLCInventors: Markus A.
