Abstract: A fibre optic coupling assembly includes a coupling assembly comprised of a spring loaded coupling lock which locks to fibre connectors together by way of spring balls located in locking grooves. The forward movement of the coupling locks, against the spring pressure of the spring, allows the disengagement of the two fibre connectors. The fibre connector has a connector housing with a crimp sleeve and an outer coupling nut. The coupling nut is threadably received over the rear end of the connector housing. The combination of the coupling nut and the crimp sleeve provides for strain relief of the fibre cable as well as pushes the fibre forward due to the radial contraction of the crimp sleeve, thereby gripping the outer insulation of the cable, and forcing the entire cable further forward upon further rotation of the coupling nut.

Abstract: Apparatus for breaking an optical fiber comprises fiber gripping units (2 and 4) each comprising a rigid block (6 or 6') having adhered thereto a strip (8 or 8') of a resilient material, for example a synthetic felt, the blocks (6 and 6') being relatively movable between an open position to receive an optical fiber (OF) between the resilient strips (8 and 8') and a closed position to clamp the fiber (OF) between the strips (8 and 8'). A fiber holder (9) is provided for applying a pulling force (P1) to the fiber (OF) to cause it to slide between the resilient strips (8 and 8') in the closed position of the blocks (6 and 6') Before being inserted between the strips (8 and 8'), the fiber is formed with a V-shaped notch (N) at which the fiber is to be broken.

Abstract: A printed circuit board connector (11) comprises a housing (12) with terminals (13,111) each having a mating portion (34); an anchoring post (32,112) with a compliant portion (33,113); and a resilient contact (35,55) trapped against the surface of a printed circuit board (37) by receipt of the compliant portion (33,113) in an unplanted through-hole (36). The compliant portion (33,113) may comprise a strip-form post (112) split to form limbs (115,115') which have been pushed out in opposite directions, relatively away from each other, parallel to the plane of the slit (123) to lie in adjacent parallel planes and subsequently pushed relatively towards each other across the plane of the slit (123) to bring portions of their oppositely facing rolled surfaces adjacent the slit (123) into partially overlapping face-to-face engagement.
