  • Patent number: 7597580
    Abstract: A connector assembly has a first part with an interior for receiving right-angle electrical terminals through an insertion end. Wire-connect segments of the terminals seat within cradle-like members aligned in sets of rows extending across the width of the interior. Electrical mating segments of the terminals extend perpendicularly from the wire-connect segments. A second part of the connector assembly has chambers for receiving the mating segments of the terminal and a compartment with inner cradle-like members aligned in sets of rows across the compartment. The cradle-like members of the first and second parts are arranged to correspond in position to each other when the second part is assembled on the first part so the wire-connect segments are clamped within the cradle-like members, reducing vibrational and other motion of the terminals within the assembly.

  • Patent number: 7594821
    Abstract: A sealing system for a connector assembly used to house one-piece right-angle electrical terminals. The assembly has a first part for receiving the terminals and allowing the terminals to be turned such that wire-connect portions of the terminal are seated in the first part and electrical mating portions of the terminals perpendicular to the wire-connect portions extend through a second part. The second part has an insertion section for receipt in an opening and recess of the first part and a chamber section for accommodating the mating portions of the terminals. A gap is formed by the relative sizes and shapes of the parts around the insertion section at an engagement area between the first and second parts. Latch features within the first part and on the insertion section secure the two parts together internally from the gap. A resilient gasket fits into the gap and seals the engagement area.

  • Patent number: 7530843
    Abstract: An electrical terminal is sealed for use in high voltage vehicle systems. The terminal has a cylindrical section positioned between a contact section for mating with another electrical contact or terminal and a crimp section for mechanically and electrically securing the terminal to an electrical wire. The cylindrical section is integral with both the contact section and the crimp section, and includes an outer surface with a circumferential groove. The groove receives and retains an o-ring seal for preventing contaminant seepage between the contact section and the crimp section when the contact section is inserted into a connector for mating with the other contact or terminal. The contact section may be either a substantially flat eyelet contact, a male contact or female contact.
