1. A connector assembly suitable for high voltage applications to connect electrical conductors having conductor wires therein, comprising:

  • first and second terminal means including respective first and second termination sections at rearward ends thereof adapted to be crimped to stripped ends of respective conductor wires, said first and second terminal means further including first and second contact sections at respective forward ends thereof adapted to matingly engage each other, and said first and second terminal means including first and second forwardly facing stop means disposed forwardly of said first and second termination sections and first and second rearwardly facing stop means disposed rearwardly from said first and second forwardly facing stop means and forwardly of said first and second termination section;

    first and second terminal housing subassembly means associated with said first and second terminal means respectively and including a respective first and second passageway extending from a rearward end to a forward end thereof within which a respective said first and second terminal means is disposed, said first and second terminal housing subassembly means including first and second rearwardly facing stop means cooperable with said first and second forwardly facing stop means of said first and second terminal means respectively to prevent axially forward movement of the terminal means, each of said first and second terminal housing subassembly means further including an enlarged passageway portion remote from said rearward and forward ends within which is disposed a first retention means between forward and rearward ends of said enlarged passageway portion in a manner preventing axially forward and axially rearward movement therealong, each said first retention means including inwardly and forwardly directed lances stoppingly engageable with a corresponding said rearwardly facing stop means of a respective one of said first and second terminal means to prevent axially rearward movement of said respective terminal means after full insertion of said respective terminal means into said terminal housing subassembly means, each said first and second terminal housing subassembly means including a second retention means secured therearound, each said second retention means including a forward end extending forwardly and radially inwardly to engage a rearwardly facing stop means around said terminal housing subassembly means and further including a rearward end spaced radially outwardly from said terminal housing subassembly means;

    said first and second terminal means, when crimped to respective said conductor wires and inserted into said first and second terminal housing subassembly means, defining first and second terminal assemblies respectively;

    first and second connector housing means including first and second terminal assembly-receiving passageways extending from a rearward face to a mating face thereof, said passageways receiving therein respective ones of said first and second terminal assemblies form said rearward face and including forwardly facing stop surfaces therealong cooperable with respective said rearward ends of said second retention means secured around respective said terminal housing subassembly means; and

    means for securing said first and second terminal assemblies within respective said first and second terminal assembly-receiving passageways of said first and second connector housing means against axially forward movement;

    each of said first and second terminal housing subassembly means including a respective first and second hood section extending forwardly and surrounding said first and second contact section of a respective said first and second terminal means after full insertion of the terminal means thereinto, a respective first and second rearward section extending rearwardly and surrounding a respective said first and second termination section and extending still farther rearwardly surrounding an insulated length of the conductor to which the respective terminal means is crimped, wherebya connector assembly is defined which is adapted to minimize corona discharge events and thereby be suitable for high voltage applications.
