Abstract: The present invention provides a multi fiber optical ferrule, a tool for forming the ferrule, and a method of making the ferrule. The multi fiber optical ferrule is formed of two ferrule halves which are either molded or cast as imprecise blanks which are machined using a broach in order to precisely cut inner surfaces thereof for receiving an array of fibers. The inner surfaces of a pair of ferrule halves are cut simultaneously in order to assure accuracy in the fiber receiving and pin receiving channels. The halves are joined together with a fiber array placed therebetween to form the ferrule.

Abstract: This invention relates to a method of making fiber optic interferometers. First, a plurality of optical fibers are bundled and placed into a sleeve. The bundle is then encased in the sleeve and the fiber ends are cut and polished. An area of cladding is stripped back from the polished fiber ends and layers of material are deposited on the fiber ends. These layers of material have varying indexes of refraction and form a grating. The bundle of optical fibers is then removed from encasing in the sleeve.

Abstract: A method of manufacturing a guide plate for use in a chip carrier socket or other electrical connector provides the precision required for close-center line spacing while minimizing the cost associated with production. A block of ceramic or the like is ground to the precise outside dimensions required. Grooves are then cut in the block of ceramic, and the ceramic is then sliced into respective guide plates. The guide plates are inserted into openings provided in the electrical connector an retained therein. The grooves are dimensioned to cooperate with contact pins of the electrical connector to precisely maintain the pins in position, whereby when a chip is positioned in the electrical connector, the pins will be in position to make an electrical connection with the pads of the chip.

Abstract: An electrical connector for connecting a first printed circuit board to a second printed circuit board has terminal contacts which provide a reliable electrical connection. The contact terminals are positioned adjacent to a board receiving recess, and are configured to make an electrical connection with the second printed circuit board when the second printed circuit board is rotated to a second position. Overstress projections provided on the contact terminals cooperate with shoulders of the electrical connector to prevent contact terminals from being deformed as the second printed circuit board is moved relative to the contact terminals. Contact projections are positioned on the contact terminals proximate a resilient contact arm. The contact projections electrically engage the resilient contact arm when the second printed circuit board is in the second position.

Abstract: An electrical connector assembly has terminals which have first resilient legs and second rigid legs. The second rigid legs cooperate with the housing to secure the terminals therein. The entire length of the first resilient leg is utilized as a resilient beam. The first and second legs also provide two parallel paths over which signals can travel. The configuration of the terminals minimize the height of the assembly and provides a reliable electrical connection over which high speed signals can travel.
