Abstract: An adapter (12, FIG. 1) is described, for mounting a passthrough on a panel (14) to hold by a wire cable or optical cable, wherein the adapter can be installed by merely pushing it rearwardly into a hole (20) in the panel. The adapter includes a tubular passthrough (16) and a molded plastic clip (18) that is mounted on the passthrough. The clip has a front end (40, FIG. 3) that forms a large washer to abut the front face of the panel, and has a sleeve (46) extending rearwardly from the washer with a rear sleeve end (50) that closely surrounds the passthrough. The sleeve has a pair of U-shaped slits (56, 64, FIG. 2), with the base of each U-slit lying most forward, to leave a latch (62, 66) having a rear latch end merging with the rest of the sleeve and a free front latch end (124, FIG. 3) which can abut the rear face of the panel. The passthrough has a recessed portion (76) into which the latches are deflected when the adapter is inserted rearwardly through the hole in the panel.

Abstract: An optical fibre connector is provided which is of simple, dirt-resistant, and easily cleaned construction. The connector includes an outer body (1, FIG. 1) having a main bore (2), a ferrule (4) lying in precision sliding fit in the main bore, with an optical fibre (9) extending through the ferrule, a spacer (15) lying against the front of the ferrule, and a spherical lens (3) lying against the spacer. The outer member (1) has a larger second bore (10). A termination sleeve (8) lies in the second bore, presses forwardly on the ferrule, extends rearwardly through a stepped bore (11) in a securing member (12), and is biased forwardly by an elastomeric part (14) in the securing member. The spherical lens (3) has an anti-reflection coating and is bonded to the front surface (17) of the spacer.

Abstract: An optical fibre cable terminating tool (16) and method for terminating a cable to a connector (13) of the type having at one end a ferrule (14) provided with a meltable adhesive therein. The tool (16) has a recess 16a for receiving and locating a connector (13) with its ferrule end projecting from the recess and permitting the end to be inserted into a heating recess of an oven. A heat sensitive element (36) is provided on the tool spaced from the recess end and this displays a change in appearance at a predetermined temperature which is indicative of a higher temperature at the ferrule at which higher temperature the adhesive is molten.
