  • Patent number: 5181863
    Abstract: A system is provided for mounting shielded cables in a manner to provide good EMI (electromagnetic interference) shielding, which facilitates terminations and enables field replacements. The system includes a backshell housing having a conductive shell (16, FIG. 1) holding an insert, the housing also having a conductive cover (24) that mounts over the rear end of the shell and that has rows of holes (46) that each pass a prepared cable end (44). After the cables are inserted through the cover holes, a ferrule assembly is attached to the cable. The ferrule assembly (60) includes a ferrule (40) crimped to each cable, a conductive elastomeric seal (50) lying closely about each ferrule crimped portion, and a clip (56) with a rear end that abuts the seal. A grating (62) with parallel beams is inserted sideways between ferrule assemblies to organize them into rows and to abut the forward ends of the clips.

  • Patent number: 5167521
    Abstract: Electrical plug connectors used in humid locations are provided with sealing elements (16, 26) at their cable ends and at their plug ends, which results in an enclosed volume of air in the interior space (27) of the plug connector. If there are fluctuations in temperature and/or pressure in the surrounding space (19), the interior space (27) is at relative overpressure or underpressure; the underpressure situation leads to seepage of water into the plug connector. In accordance with the invention, this is avoided by forming the sealing elements (16,26) of an air-transmissive yet water-repellant material, preferably polytetrafluoroethylene (PTFE), so that they can also serve as pressure equalizing elements. Plug connectors according to the invention are particularly well suited for use in spaces subjected to wide-ranging temperatures and/or to water infiltration resulting from high ambient humidity.

  • Patent number: 5116236
    Abstract: An electrical connector is provided with a transversely aligned terminal position assurance (TPA) component that is slidably insertable into a transverse keyway in the connector housing. The TPA component includes a plurality of flexing primary latches and a corresponding plurality of static secondary locks. The flexing primary latches are disposed to align with the terminal receiving cavities of the housing when the TPA component is in a pre-load position. The terminals can be inserted into the housing with the TPA component in this pre-load position such that the flexing primary latches at least temporarily retain the terminals in the housing. Upon complete insertion of all terminals the TPA component is indexed transversely into a final locked position such that the static secondary locks thereof positively engage each terminal to ensure complete insertion. A symmetrical front mating seal is configured to be held in the housing by suction to prevent separation during unmating.

  • Patent number: 5035638
    Abstract: An electrical connector (2) has terminal receiving cavities (48) in which are provided terminals (4). Each terminal (4) has a mating end (10, 12) and a conductor receiving end (26) for receipt of a conductor (6) therein. The terminals have insulating cover means (8) which are positioned over the conductor receiving ends (26). The insulating cover means are secured to the terminals by securing means (22) which are integrally attached to the terminals. The configuration of the insulating cover means is such to eliminate air voids provided in the terminal receiving cavities (48) of the connector (2), thereby protecting the terminals from the corrosion which can occur due to the moisture provided in the air voids condensing when the connector is exposed to temperature fluctuation.
