A fiber optic connector comprising a coupling shell encircling a glass end portion of a bushing disposed axially within an encircling ferrule having an end portion extended axially out of the shell and terminating in a dish-shaped end surface provided with a central aperture through which an optical fiber element extending axially through the glass end portion of the bushing and the ferrule protrudes to terminate at a planar end surface spaced axially from the aperture, the dish-shaped end surface being curved concavely and continuously from the aperture radially to a circular rim which is spaced a greater axial distance from the aperture than the planar end surface of the optical fiber element. The method of assembling the fiber optic connector onto the optical fiber element including the steps of securing the glass end portion of the bushing to a body portion thereof with bonding material insensitive to ultraviolet light and securing the optical fiber element to the glass end portion with bonding material sensitive to ultraviolet light. A fiber optic junction assembly comprising two of the fiber optic connectors having the circular rims of their respective dish-shaped end surfaces disposed in abutting relationship and forming a biconvex enclosure wherein the planar end surfaces of the respective optical fiber elements are disposed in axial spaced alignment with one another.

A phone jack assembly comprising a piggy-back array of two phone jack housings made of moldable dielectric material and having integral walls defining respective axial cavities wherein a phone jack plug may be inserted; and a plurality of pairs of wire terminals extending downwardly from the lower housing of the array for insertion into respective apertures in a connecting device. Each of the wire terminals is recessed within a respective groove molded into the outer side surfaces of the housings and one of each pair has a portion extended into a cavity of one of the housing for electrical engagement with a portion of a phone jack plug inserted into the cavity. Also each of the wire terminals is provided with a laterally bent portion for pressingly engaging side wall surfaces of the respective groove to support the wire terminal when being inserted into or withdrawn from said respective aperture in the connecting device. The lower housing of the array may have an upper surface provided with a ridge which fits snugly into a channel in the lower surface of the overlying housing in the array; and some of the wire terminals recessed in said groove extend over the top surface of the upper housing in the array to aid in holding the housings of the array together as an assembly when being mated to or disconnected from said connector device.

The invention provides a modular structure for electrical connections with an integral molded frame wherein a forward portion of the frame has holes to receive electrical conductors and a rearward portion carries one or more electrical contact assemblies, said frame being adapted to fit into the rear of a panel, with or without elimination of screws previously used for panel mounting, and with the elimination of separate sleeves that have to be brazed on the jack frame, thereby reducing manual operations and simplifying manufacture while providing versatile modular components especially useful in telephone switchboards and apparatus, multiplex and microwave systems, television and broadcast equipment and other control panel applications where small size and reliability are prime engineering and operating parameters. Other features are the provision of a new extruded panel, and the provision of a special type of jack sleeve made from a wrapped up stamping.

The invention provides a time indicating device which contains an endless indicating belt carrying indicating means thereon that define three or more equally spaced segments of said belt, the belt passing beneath a face plate with an elongated opening therein mounted adjacent the belt so that from time to time said indicating means carried by said belt are visible through said opening, the length of said opening substantially corresponding to the length of one of said segments so that when said belt is moved past said opening there will be a moment when one of said segments will appear over the entire length of said opening. The device is especially useful in clocks where a plurality of belts are employed which are driven at different speeds to indicate seconds, minutes, hours or, if desired, additional belts can be used to indicate days, weeks, months or other time periods.
