Abstract: In an optical fiber connector for joining the ends of pairs of light conducting fibers which includes a mounting plate provided with guide grooves receiving the fiber ends and a pressure plate structure disposed on top of the mounting plate and hinged and latched thereto, guide grooves are formed only in the mounting plate and have a depth greater than the fiber radius and the pressure plate structure has elastic clamping members formed therefrom so as to project toward the mounting plate for resilient engagement with the respective optical fiber ends and the clamping members engaging the ends of each pair of fibers are spaced such that an open area is provided at the fiber joints to provide for visibility of and access to the joints, the mounting plate and pressure plate structure having at their ends clamping structures for engaging and axially fixing the position of the fibers where the connector is closed.

Abstract: In a connector for a flat conductor strip cable which consists of a two-part housing in which the cable is engaged by compression, one of the housing parts has a cavity with a cable support surface disposed at a first acute angle with respet to the direction in which the two housing parts are movable in engagement with one another and the other housing parts carry leaf spring contact members disposed at a second acute angle with respect to the same direction, which angle is smaller than the first angle and the leaf spring contact members have cutting edges adapted to cut through the insulation of the conductor strip cable and the slide onto the surface of the flat conductors upon compression of the housing parts thereby providing for firm contact of the leaf spring contact members with the flat conductors.

Abstract: In a method of manufacturing a contact construction material structure a corrosion resistant contact layer of silver, palladium, or alloys thereof is applied to a metal base, a gold coating is applied to the contact layer surface by molecular gold material deposition and the contact construction structure is then heated to 350.degree. to 650.degree. C. for a short period of time to cause diffusion of the gold coating into the corrosion resistant contact layer to further improve its corrosion resistance.
