Abstract: An apparatus is provided for use in molding a ferrule which must hold an optical fiber cable so the optical fiber lies precisely concentric with the cylindrical outside surface of the forward portion of the ferrule. A corepin which lies within a mold to form a ferrule cavity between them, has a rearward end held to the mold and a forward end which must be held precisely concentric with the inside surface of the ferrule cavity. A bushing of clover leaf design is positioned in the mold cavity, and has three radially-extending arms that precisely center the forward end of the corepin, while leaving spaces between the arms through which plastic can flow during the molding of the ferrule. The radially-outer arms of the bushing are tied by tying portions whose radially inside surfaces form an interrupted cylindrical outside surface of the ferrule.

Abstract: An improvement is described in a type of connection system wherein an insertable circuit assembly can be pushed into a housing which contains an inplace circuit assembly, until terminals on the two assemblies lie opposite one another but out of contact, at which time a deflecting member on one of the assemblies is moved sidewardly to deflect its terminals into contact with the other terminals. In the present system the inplace assembly is movable along with the insertable assembly after they engage one another. As the assemblies move, a cam on the housing moves the deflecting member sidewardly to deflect the terminals.

Abstract: A substantially continuous "bracelet-like" grounding and electromagnetic shielding device for placement in a circumferential cavity formed by an annular groove in at least one of two overlapping body portions of mating electrical connector subassemblies. The device is formed as a flat stamping and curved into a "bracelet" shape with closely interleaving first and second axially extending flat fingers. A base portion in the form of a ring extending about the circumference of the groove and having a first set of substantially flat, integral, axially-extending fingers spaced circumferentially and occupying substantially the entire axial dimension of the cavity.
