Abstract: A connection contact in a single piece has two insulation displacement contacts (14) having each an insulation displacement slot (16), a contact and guiding surface (20) and a shearing element. The connection contact further has two contact legs (22, 23) one end of which is connected to an insulation displacement contact (14), a home contact formed between the free ends of the contact legs and a section (27) that links the insulation displacement contacts (14). The disclosed connection contact in a single piece is characterized in that the linking section (27) is designed as a substantially U-shaped loop (28). As lead-shearing element, an insulation displacement contact (14) is associated to each leg (30) of the U- or V-shaped loop (28), so that the contact pressure between the contact legs of the home contact can be easily adjusted as desired. A fatigue-proof home contact is thus obtained, which is also economical to produce.

Abstract: A waterproof packing is axially compressed between a pair of female and male connectors in intimate contact therewith to form a liquid-tight seal between the two connectors. An axial thickness T1 of a radially outward portion of a compression portion of the packing which can be compressed between the two connectors is smaller than a thickness T2 of a radially inward portion thereof. With this construction, the radially-outward bulging or deformation, caused by the axial compressive deformation, proceeds progressively from the radially inward portion, so that the radially-outward bulging or deformation can be suppressed to a low level.

Abstract: An optic module contains a flexible circuit board forming a cable which connects between an optical sub-assembly and a rigid interconnect structure within the optic module. The cable includes lands proximate to through holes for soldered connection to leads which extend from the optical sub-assemblies and are substantially smaller than the hole. A soldering bridge comprising several separate tabs equally spaced about the land and which project from the land into the hole and are very flexible in relation to the lead so that the lead can be placed in any radial position within the hole, but regardless of the position of the lead within the hole the projections of the soldering bridge project close enough to the lead so that during wave soldering a joint of desired configuration is produced. The soldering bridge can be integral with the land so that the bridge helps connect the solder to the land allowing the land to be smaller and thus providing for closer spacing between connection holes.
