A reduced area imaging device is provided for use in medical or dental instruments such as an endoscope. The imaging device is provided in various configurations, and connections between the imaging device elements and a video display may be achieved by wired or wireless connections. A connector assembly located near the imaging device interconnects the imaging device to an image/power cable extending through the endoscope. The connector provides strain relief and stabilization for electrically interconnecting the imager to the cable. The connector also serves as the structure for anchoring the distal ends of steering wires extending through the body of the endoscopic device. The connector includes a strain relief member mounted over a body of the connector. The connector allows a steering wire capability without enlarging the profile of the distal tip of the endoscopic device.

A fiber optic stub fiber connector for reversibly and nondestructively terminating an inserted field fiber having a buffer over at least a portion thereof. The connector includes a housing and a ferrule including a stub fiber disposed within and extending from a bore through the ferrule. The ferrule is generally at least partially disposed within and supported by the housing. The connector further includes a reversible actuator for reversibly and nondestructively terminating the inserted field fiber to the stub fiber. The reversible actuator includes a buffer clamp for engaging with the buffer to simultaneously provide reversible and nondestructive strain relief to the terminated field fiber.

An adjustable strain relief boot includes a stationary portion and a moving portion slidably connected to the stationary portion. The adjustable strain relief boot is used to guide an optical fiber away from a connector of the optical fiber. In application, the stationary portion of the adjustable strain relief boot is press fitted onto to the connector. The adjustable strain relief boot provides for a predetermined, fixed angle of departure of the optical fiber away from the connector. The fixed angle of departure can be adjusted by the operator from a first position to a second position. The fixed angle of departure is adjustable between forty five and ninety degrees. In a locked position, the moving portion can not move relative to the stationary portion since actuator engagement teeth of an actuator arm of the stationary portion engage teeth of the moving portion. In an unlocked position, a force is applied to a release tab of the actuator arm of the stationary portion so as to disengage the actuator engagement teeth of the stationary from the teeth of the moving portion so as to allow the moving portion to move relative to the stationary portion. Due to the resiliency of the actuator arm of the stationary portion, when the force applied to the release tab is removed, the actuator arm tends to move towards its undeflected position thus engaging the actuator engagement teeth with the teeth of the moving portion.

An equipment fan has a housing (22) that externally defines an air passage opening (41) provided in the fan (20). The fan has a motor (21) for rotatably driving blades (40) about a rotation axis (23), as well as a carrier element (51), provided between the motor (21) and the housing (22), which extends transversely to the passage (41) and is configured as a trough (53) that serves to receive an electrical lead (52) and guides the lead along a predetermined path from the motor (21) to a location (64) on the housing (22). The fan also has a deflection device (50) which, by deflecting the lead (52) at a first deflection location (55) and at a second deflection location (84) and in at least two planes extending at a predetermined angle with respect to one another, effects strain relief for the lead (52) that proceeds to the motor (21).

The preferred embodiments of the present invention include an optical splitter module having connectorized pigtails that are stored on the bulkhead faceplate of the module. The module includes an optical splitter output harness, for example, a ribbon cable assembly attached to the bulkhead with rugged strain relief mechanism. The ribbon harness is converted to individual pigtails with connectors which are stored on adapter receptacles on the faceplate. Adapter receptacles used may optionally be half receptacles when storage is the only desired function or may be full receptacles when access to the pigtail ferrule tip is required. Access to the ferrule tip may be required for attaching fiber optic terminators to eliminate undesirable reflections caused by unterminated connectors. The module provides an administrative location for splitter outputs prior to being connected individually into service. The module also provides an administrative storage location for splitter outputs taken out of service as a temporary staging area before being reassigned and connected individually into service again.

A fiber routing tray to hold, organize, and route fiber cables from external sources to other optical modules and optical components. The fiber routing tray mechanical device comprises a fiber entry block, fiber channel slot, retention bar with fiber clamps, fiber clamping slots, curved fiber routing fence, and a fiber exit opening. A retention bar with a contoured fiber retention clamps is used to hold fiber cables in place, provide a strain relief to a fiber cable, and distribute uniform clamping force on the fiber cable preventing insertion and return losses. Curved fiber channel slots with a preferable width help route fiber cables and prevent them from overbending. In addition, these fiber channel slots control the extension and retraction distance of the fiber cables during external fiber cable assembly. A curved fiber routing fence help route fiber cables and help prevent them from over-bending and tangling inside of the fiber reel tray. An exit opening allows fiber cables to drop below the fiber tray before the fiber cables are attached to the optical devices and optical modules.

A connector adapter that can be used to directly connect a peripheral device to a host device. The connector adapter is adjustable so as to allow selective reorientation of the peripheral with respect to the host device. The connector adapter includes a limiting mechanism that restricts the degree to which the adapter can be selectively rotated. In addition, the adapter includes an indexing mechanism that allows the position of the adapter to be locked in predetermined positions. In one embodiment, the connector adapter is partially formed from a compliant material so that the adapter can bend when submitted to an external force, and thereby resist breakage. The connector adapter may also have a physical geometry that provides additional strain relief, such as a plurality of serrations formed on the outer surface. An extension spring can be positioned within the connector adapter so as to return the adapter to substantially its original shape when the external force is removed.

The assembly may further be installed directly into a mounting structure for use as a patch panel. The fiber optic module assembly may be attached in a vertical orientation, facilitated by an articulated strain relief boot that pivots and rotates for cable management, which reduces the vertical footprint of the fiber optic module assembly. Embodiments of the fiber optic module assembly may be connected to the rear or side of a mounting structure for optical connection to pigtailed modules. The fiber optic module assembly may have a modular connector interface for mating dissimilar fiber optic connector assemblies.
