  • Patent number: 8556520
    Abstract: 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.

  • Patent number: 8556522
    Abstract: Connectors and cable assemblies having a label stored in a label storage area of a component of the connector along with methods for making the same are disclosed. The label is extendable from the label storage area with a label length that is longer than a length of the label storage area, thereby providing the craft with adequate space for marking information. Suitable components of the connector for the label storage area include housings, boots, clips and the like. Further, the label storage area protects the label from damage while also maintaining a relatively small footprint for the connector.

  • Patent number: 8511908
    Abstract: A connector has first and second connector units, each unit incorporating an oil-filled chamber housing one or more contact elements to be joined. At least one connector unit has a face seal assembly which seals the forward end of the contact chamber in the unmated condition. The face seal assembly comprises three elements. One element is an annular elastomeric seal situated radially outward. The two other elements are inner seal elements which are pressed together radially to form a substantially disc-like shape. The resulting disc-like shaped seal fills the central, circular end face opening of the outer annular seal. As the connector units are mated, elements of the elastomeric face seal assembly are displaced, one axially, and others both axially and radially, creating an opening between the oil-filled chambers that is sealed from the outside environment.

  • Publication number: 20120237166
    Abstract: A connector assembly including an actuator body that extends along a central longitudinal axis between a pair of connector ends. The actuator body is movable along the longitudinal axis and has an actuator cam feature. The connector assembly also includes an assembly frame that is operatively coupled to the actuator body and is movable along a mating axis that is non-parallel relative to the longitudinal axis. The assembly frame defines a connector compartment and has a frame cam feature that is positioned to engage the actuator cam feature. The actuator and frame cam features slidably engage each other when the actuator body is moved along the longitudinal axis thereby moving the assembly frame along the mating axis. The connector assembly also includes a mating connector that is held by the assembly frame within the connector compartment. The assembly frame is configured to move the mating connector in a mating direction.

  • Patent number: 8267595
    Abstract: A one-piece LC type optical fiber adapter is provided. The LC type adapter of the present invention has fewer parts than a conventional one. Therefore, it is simpler and easier to assemble the LC type adapter of the present invention. In addition, the main body of the LC type adapter is unitary thereby avoiding the prior art problem that the stresses cause the two halves of the adapter to separate from each other after time.

  • Patent number: 8256970
    Abstract: An improved, reversibly terminable fiber stub connector assembly is provided that can be readily and positively terminated in the field using simple termination tools. This allows repositioning or replacement of fiber optic cable field fibers if termination is not acceptable in performance. The tool may be a hand-held tool, or used in conjunction with a connector support structure to provide simplified and expeditious field termination of fiber optic cables. The cam tool can include a throughbore that enables connection of a patchcord to the stub fiber of the connector during or shortly after termination without removal of the termination tool. Accordingly, field testing of the connection can be made at the site of termination.

  • Patent number: 8240927
    Abstract: A cable attachment system is disclosed for attaching a fiber optic connector to a fiber optic cable. In particular, strength members of the fiber optic cable are crimped between a crimp sleeve and a cable anchor, and the cable anchor is anchored to the fiber optic connector. An end of the crimp sleeve is adapted to receive an end of a jacket of the fiber optic cable. An end of the cable anchor includes a nipple adapted for insertion into the end of the jacket. An end portion of the jacket is crimped between an intermediate portion of the crimp sleeve and the nipple of the cable anchor. A support portion of the crimp sleeve, positioned between the end and the intermediate portion of crimp sleeve, supports a transitioning portion of the jacket beyond the end of the cable anchor.

  • Patent number: 8226305
    Abstract: A fiber optic connector release mechanism for releasing a transceiver module in a cage permanently mounted on a PCB is disclosed. The release mechanism includes a bail rotating a U-shaped flange through a two stage travel path to urge the bail forward in a slide path on the transceiver module. The release mechanism includes a boss disposed on one of the bail and the arm assembly and a dimple disposed on another of the bail and the arm assembly to secure the bail in a locked position. As the bail moves forward from the locked position, wedge elements at the end of arms extending rearward may contact locking tabs on the cage, forcing the locking tabs outward. As the locking tabs are forced outward, the shoulders of the transceiver module are released, and the transceiver module is free to slide out of the cage.

  • Patent number: 8206043
    Abstract: A fiber optic connector release mechanism is disclosed. The mechanism may be used to release a transceiver module housed in a cage that is permanently mounted on a printed circuit board. The release mechanism may include a cam mounted bail that rotates a U-shaped flange through a two stage travel path to urge the bail forward in a slide path on the transceiver module. As the bail begins to move forward, wedge elements at the end of a pair of slide arms extending rearward from the bail may contact locking tabs on the cage, forcing the locking tabs outward. As the locking tabs are forced outward, the shoulders of the transceiver module are released, and the transceiver module is free to slide out of the cage as the operator pulls on the bail.

  • Patent number: 8192089
    Abstract: A connector has first and second connector units, each unit incorporating an oil-filled chamber housing one or more contact elements to be joined. At least one connector unit has a face seal assembly which seals the forward end of the contact chamber in the unmated condition. The face seal assembly comprises three elements. One element is an annular elastomeric seal situated radially outward. The two other elements are inner seal elements which are pressed together radially to form a substantially disc-like shape. The resulting disc-like shaped seal fills the central, circular end face opening of the outer annular seal. As the connector units are mated, elements of the elastomeric face seal assembly are displaced, one axially, and others both axially and radially, creating an opening between the oil-filled chambers that is sealed from the outside environment.
