Connector housing and optical waveguide assembled body
A connector housing includes a housing including a front end portion, a base end portion having end opening, and an inner cavity portion extending from the front end portion to the base end portion and formed such that a front portion of a flexible optical waveguide having band shape is inserted from the end opening into the cavity to the front end portion. The cavity has a length that extends in longitudinal direction of the waveguide, a width that extends in width direction of the waveguide, and a height that extends in thickness direction of the waveguide, and the housing has a pair of walls forming a pair of inner surfaces facing each other in the cavity such that the inner surfaces is gradually increasing a separation distance between the inner surfaces in the thickness direction of the waveguide toward base end side of the housing at the end opening.
Two-part and terminal connectors with conductor management device for use in hazardous environments
A terminal connector or two-part connector comprising male and female parts having respective contact pins and contact receivers (10,15) of a construction generally known in the art. In the body (1) of the or at least one part, closely juxtaposed a terminal block (9), there is provided a conductor management device (8) adapted to receive conductors (12) as they are unbundled from the connected cable or reel and support the unbundled or individual conductors through the transitional region of the connector part to where they are secured at the terminal block (9). The conductor management device (8) has through body apertures defining each conductor path (14) to align each conductor with its respective receiver (13). In a different configuration, the conductor management device provides strain relief to the conductors, provides support and conductor rigidity, provides a locking means and is a bore modifier.
Cable assembly with cable attach structure having off-axis fiber routing
A cable attach structure for attaching a fiber-optic cable to a rear end and a connector to a front end is disclosed. In one embodiment, the cable attach structure is a portion of a fiber optic cable assembly having a fiber optic cable with at least one optical fiber and a connector attached to the optical fiber. The fiber optic cable is attached to the cable attach structure at a rear end and circuit board is attached to the cable attach structure at the front end. The cable attach structure also routes the at least one optical fiber away from the centerline of the connector for off-axis fiber routing. In other embodiments, the optical fiber can enter the connector from a first direction and attach to the connector in a second direction if desired.
Structures and method for thermal management in active optical cable (AOC) assemblies
Disclosed are structures and methods for active optic cable (AOC) assembly having improved thermal characteristics. In one embodiment, an AOC assembly includes a fiber optic cable having a first end attached to a connector with a thermal insert attached to the housing for dissipating heat from the connector. The AOC assembly can dissipate a suitable heat transfer rate from the active components of the connector such as dissipating a heat transfer rate of 0.75 Watts or greater from the connector. In one embodiment, the thermal insert is at least partially disposed under the boot of the connector. In another embodiment, at least one component of the connector has a plurality of fins. Other AOC assemblies may include a connector having a pull tab for dissipating heat from the assembly.
Boot for optical connector ferrule
In a boot B for an optical connector ferrule including a rear opening portion 21b used to insert an optical fiber tape T having an optical fiber at a front end thereinto and a front opening portion 21a used to expose the optical fiber of the front end of the inserted optical fiber tape T to the outward front side, the boot is inserted into an insertion opening portion 14 formed at a rear end side of a ferrule body 10 and a surface of the boot B is provided with protrusions 22a, 22b, and 22c formed so as to be crushable when the protrusions are inserted into the insertion opening portion 14 of the ferrule body 10 in a direction orthogonal to the insertion direction of the boot B.
OPTICAL FIBER CONNECTION AND METHOD OF IMMOBILIZING THE SAME
An optical connection includes a first connector, a second connector, a first holder connected to the first connector, where the first connector is secured by the first holder by tight fitting or bonding, and a second holder connected to the second connector, where the second connector is secured by the second holder by tight fitting or bonding. An adapter can be configured to connect with the first connector and the second connector, and a third holder can be connected to the adapter and interconnected between the first holder and the second holder.
Mechanical interface between a fiber optic cable and a fiber optic connector
A fiber optic connector and cable assembly includes a cable and a fiber optic connector. The connector has a main connector body, a ferrule, a spring for biasing the ferrule, and a spring push for retaining the spring within the main connector body. A crimp band is provided for securing the fiber optic cable to the fiber optic connector. The crimp band includes a first portion securing a cable strength member. The crimp band also includes a second portion crimped down on a jacket of the cable. The crimp band further includes an inner surface having gripping structures for gripping the strength member and/or the jacket.
Guide pin retainer and optical connector using the same
The present invention provides a pin retainer comprising a base, and a retaining structure coupled to the base. The base has a through slot, two through-holes respectively formed at two opposite sides of an opening of the through-slot formed on a surface of the base for respectively accommodating guide pins, and first engaging structures respectively formed on two lateral surfaces of the base. The retaining structure has a pair of lateral plates slidably coupled to the two lateral surfaces. Each lateral plate has second engaging structure corresponding to the first engaging structure, and a positioning plate having a holding structure. The second engaging structure is combined with or released from the first engaging structure depending on the positions of the retaining structure. Alternatively, the present invention also presents an optical connector using the pin retainer.
STRAIN RELIEF BOOT AND FIBER OPTIC CABLE ASSEMBLY INCLUDING THE SAME
A strain relief boot and a fiber optic cable assembly are described. The strain relief boot has a first conduit made of at least a first material. The first conduit has a front segment and a rear segment. The rear segment includes at least one discontinuity to make the rear segment more flexible than the front segment. The rear segment also includes at least one projection extending outwardly from the rear segment at a location adjacent to the at least one discontinuity. The strain relief boot also has a second conduit made from at least a second material that is less rigid than the first material. The second conduit at least partially surrounds at least the rear segment of the first conduit and extends rearwardly of the first conduit.
Ruggedized fiber optic connectors and connection systems
Example fiber optic connector systems have rugged, robust designs that are environmentally sealed and that are relatively easy to install and uninstall in the field. Some connector systems can be configured in the field to be compatible with different styles of fiber optic adapters. Some connectors include a first seal (90) on a release sleeve; and a second seal (88) between the release sleeve and a connector body. Other connectors include a seal (139) and a flexible latch (136) on a connector. Other connectors include a protective structure (228, 328, 428) that mounts over the fiber optic connector.
