Abstract: Couplers for a cable trough system including a terminal end sized to receive a terminal end of a trough member along a longitudinal direction of the body. A spring may be coupled to the body for securing the terminal end of the trough member to the coupler, the spring including first and second spring arms extending generally in opposition to one another in a plane generally parallel to the longitudinal direction. The spring may be received in a slot formed by the trough member. Also included may be a spring release mechanism coupled to the body, the spring release mechanism sliding in the longitudinal direction between a locked position, such that the first and second spring arms engage the terminal end of the trough, and an unlocked position, such that the first and second fingers release the first and second arms of the spring.

Abstract: A fiber optic switch package and method of assembling the same with improved protection of the fibers and simple assembly. A fiber support device has passages that receive optic fibers and help align those fibers with respect to an optic switch component. In addition, the fibers that extend into the interior of the fiber support device are isolated from strains that may occur on the fibers that extend external to the fiber support device.

Abstract: A cable trough is provided including a bottom portion and two upstanding sides extending from the bottom portion to define a cable pathway. The upstanding sides define an enlarged central portion of the cable trough, and the bottom portion including at least one exit trough portion. The exit trough portion can be centrally located, with a bypass pathway on either side. At least one separator wall is provided to separate the exit trough portion from each bypass pathway. A component flange is also provided extending from one of the upstanding sides. The cable trough can also include a cable storage pathway. Alternatively, two exit trough portions can be positioned on opposite sides of the cable trough adjacent each upstanding side, and on opposite sides of a central bypass pathway.

Abstract: A coupling for a cable routing system includes wall guides spaced apart by a thickness equal to a thickness of the walls of fiber troughs to be joined by the coupling. The wall guides carry a fastener system including a bracket disposed to oppose an external surface of a trough or fitting attached to the coupling. A fastener is carried on the bracket and is axially drivable to pierce and penetrate into the wall thickness of a coupled trough.

Abstract: A fail-safe device is provided for a thyristor where the thryistor has a body member with extending tip, ring and ground leads. The fail-safe device includes an electrically conductive spring member having first, second and third contact ends. The spring member is sized to be fitted over the thyristor body with the first contact end opposing the tip lead, the second contact end opposing the ring lead and the third contact end opposing the ground lead. A dielectric spacer is provided disposed to space the first and second contact ends from the tip and ring leads. The spacer means is formed from a material selected to deform under a force of the bias of the spring at an elevated temperature generated in response to the thyristor failing to ground the tip or ring leads during an overvoltage condition.

Abstract: A test plug is disclosed for alternatively providing releasable electrical connection between a test lead and a first and second electrical contact where the first contact is a female contact and the second contact is a male contact. The plug includes a housing sized to be manually engageable and having a slot formed through a first end of the housing. A plunger is slidably disposed within the housing and slidable between an extended position and a retracted position with the plunger having a contact portion sized to extend through the slot and be received within the female contact when the plunger is in the extended position. The contact portion is further sized to be received within the housing when the plunger is in the retracted position with the slot being unobstructed to the insertion of a male contact. A first electrical contact point is disposed within the slot and yieldably biased into electrical connection with a male contact received within the slot.
