  • Patent number: 8029322
    Abstract: An electrical connector that includes a plug insert having a dielectric body and having a pair of contact channels. The contact channels have central axes that extend parallel to each other in a common direction. The contact channels are defined by respective channel walls and are separated by an inter-channel portion of the dielectric body. The channel walls have wall perimeters that extend around the corresponding central axes. The electrical connector also has a contact sub-assembly that includes mating contacts that are received in the contact channels and retention clips that are positioned within the contact channels between the mating contacts and the channel walls. Each of the retention clips has a concave body with an open side. The concave body extends partially about the wall perimeter with the open side positioned along a portion of the wall perimeter. The retention clips are oriented to face one another.

  • Patent number: 7997923
    Abstract: A connector assembly includes a housing, a grommet, and a cable organizer. The housing includes an interior chamber. The grommet is disposed in the interior chamber of the housing and extends between a forward end and an opposite exit end. The grommet includes openings extending through the grommet with insulated conductors extending through the openings and joined with contacts such that the contacts project from the forward end. The cable organizer is disposed proximate to the grommet and includes channels extending through the cable organizer with the cables extending through the channels. The cable organizer limits bending by the cables at the exit end of the grommet.

  • Patent number: 7549885
    Abstract: An electrical connector assembly is disclosed that includes a receptacle connector and plug connector. The receptacle connector includes a receptacle housing having a top surface and a bottom surface, a support plate, spacers configured to retain the support plate adjacent to the top surface, and a post retained against the support plate by a spring and a fastener configured to releasable assemble the post and the support plate. The receptacle connector is less complex, lighter, and less expensive than receptacle connectors entirely made of a unitary composite, metal, or metallized composite.

  • Patent number: 7527523
    Abstract: A power terminal and a method for making a power terminal having an electrically insulated connector body. A terminal insert is incorporated into the connector body and has at least one threaded electrically conductive member engaged with the terminal insert. The conductive member also includes a cap portion. The terminal insert is formed from a substantially rigid material and is configured to resist torque and pull out forces provided to the conductive member.

  • Publication number: 20080252158
    Abstract: A power terminal having a unitary connector body. The body includes at least one opening therethrough. The opening is configured to receive an electrically conductive member. The body further includes a recess configured to receive a cap portion of the electrically conductive member. The connector body has an electrically insulative coating on at least a portion of a surface thereof. The insulative coating provides sufficient electrical insulation to substantially prevent electrical communication between the electrically conductive member and the connector body. A method for fabricating a power terminal is also provided.
