The frame serves as a common datum for the electrical and fiber optic backplanes, and includes integral mating interface features for enabling line replaceable module connectors having a common shell to mate with the separate electrical and fiber optic connector structures on the backplane. The optical backplane is a one-piece structure to which pairs of individual fiber optic connectors, including input/output connectors, may be directly secured via a simple retention plate arrangement, the fiber optic connectors all having the same orientation to enable direct routing of fiber ribbons between rows of connectors serving different line replaceable modules.

Abstract: The present invention relates to a miniature light bulb socket featured by the capability of preventing the rupture of electrical wires at deflection points. The light bulb socket according to the invention has primarily two semi-circular grooves each formed on two opposed side walls thereof. The two grooves are located on such positions that enable the outwardly extending electrical wires to deflect at different points or levels when the wires bend towards two sides so as to avoid ruptures of electrical wires resulting from repeated reversal deflection at the same position. Therefore, the socket structure of the invention can prolong the service life of a miniature light bulb series and enhance the efficiency.

Abstract: A mechanical strain relief for a cable is firmly attached directly to the using of the connector to which the cable termination is plugged into. The strain relief has a split clamp aligned perpendicularly to the cable and extends from the housing sufficiently such that the clamp does not interfere with the use of a watertight rubber boot bonded to the housing to make the connector watertight. The clamp is opened and the cable is inserted into the connector. The clamp is then closed and tightened against the cable, such that any forces on the cable are transmitted through the strain relief to the housing. A guard extends from the strain relief and is shaped to loop around the cable to provide protection for the connector from foreign objects which would otherwise strike the termination or connector.

Abstract: A connector for use with a ribbon cable grounds alternate conductors of a fine pitch ribbon cable, and allows selected conductors associated with the connector signal contacts to be grounded. The connector is readily adaptable to differing grounding configurations. The connector includes a plurality of signal contacts housed within an insulative body.

By altering the second ground bus, the grounding scheme of the connector can easily and quickly be altered. A latching cover is provided for securing the ribbon cable to the connector body and against the signal contacts, the first ground bus and the second ground bus.
