Interconnecting cables and harnesses shall be designed with physical constraints (keying, sizing, polarization, etc.) to prevent incorrect mating/interchanging with similar sized/colored connectors. Hybrid cables/harnesses (copper/fiber optic/coaxial conductors) shall be designed to comply with the requirements of the most sensitive and demanding component (typically the fiber optic cable) in the assembly.Įach cable/harness shall be identified by a permanent label/marking.Įach connector shall be identified by a permanent label/marking affixed directly to the connector body, or to the cable adjacent to the connector. Connectors on ESD sensitive hardware shall be protected by ESD rated dust caps/covers. The mating surfaces of all unmated connectors shall be protected by covers during storage, handling and installation. Connector cable clamps and cable straps are properly set. Harnesses exhibit a neatly organized layout with smooth bends and sufficient stress relief. The use of right-angle connectors shall be minimized and restricted to applications where stress-free mounting of the cable assembly can be assured. Harnesses should be designed so that coaxial/fiber optic cables are located at or near the bundle center to minimize flexure and to provide additional protection.Ĭoaxial cable (flexible, semi-rigid, rigid) and fiber optic cables shall exhibit a neatly organized layout, with smooth bends and sufficient stress relief.Ĭonnectors shall be straight, right-angle or flange-mount. Often the most overlooked and ignored component of any electrical/electronic design, cable and harnesses are essential to the accurate and rapid transmission of data and control signals.Ĭonnector backshells shall be potted and molded, or use stress relief boots as required, in accordance with applicable engineering documentation.Ĭables and harnesses shall not be subjected to bending forces resulting in radii less than the minimum specified for the most sensitive component (i.e.: coaxial, fiber, etc.) in the assembly.
