An apparatus and method for field attaching an electrical connector to an MC-HL type of cable includes a housing having a built-in ninety degree radius. The housing includes sockets at each end, one for attachment to an oil field wellhead, for example, and the other end to the MC-HL cable. Various component parts are described along with both audible and visual verification that proper attachment has occurred. A method of securing the cable to the connector to provide the required strain relief and not damage the metal cladding is disclosed.

1. A field-attachable, disconnectable electrical connector for use with MC-HL cable, comprising:(a) a housing, said housing including a first end and an opposite second end, said first end including a plurality of electrical conductors attached thereto and said second end adapted for connecting to a stationary electrical connector, and including an electrical continuity from said plurality of electrical conductors to said stationary electrical connector; (b) means for providing an environmental seal intermediate said cable and said connector and wherein said means for providing an environmental seal includes a sealing grommet that is disposed over said plurality of electrical conductors and adjacent to said first end of said housing, and wherein said sealing grommet includes a groove on its peripheral surface that is adapted to permit at least one ground wire to pass through said groove, and wherein said ground wire includes means for electrical and mechanical connection to said first end of said housing; and (c) wherein said cable is secured to said connector. 2. The field-attachable, disconnectable electrical connector of claim 1 wherein said sealing grommet is disposed over said plurality of conductors and adjacent to said first end of said housing, and wherein said sealing grommet includes a groove therein that is adapted to permit at least one ground wire to pass through, said ground wire including means for electrical and mechanical connection to said first end of said housing and including a backshell, said backshell including a cylindrical shape and threads adapted to attach a first end of said backshell to said first end of said housing, and wherein said backshell includes an epoxy therein sufficient to fill a first void.3. The field-attachable, disconnectable electrical connector of claim 1 including a retaining nut that is adapted to cooperate with portion of said housing sufficient to urge an armor grip to engage a predetermined amount with an armor cladding of said cable.4. The field-attachable, disconnectable electrical connector of claim 1 including a backshell, said backshell including a cylindrical shape and threads adapted to attach a first end of said backshell to said first end of said housing, and wherein said backshell includes a second opposite end and wherein said second opposite end includes second threads, and including a retaining nut that is adapted to cooperate with said second threads sufficient to urge a pair of split armor grips to engage a predetermined amount with an armor cladding of said cable, each of said split armor grips including a substantially cylindrical shape with a first taper at a first end thereof and a second taper at a second end thereof, wherein when said retaining nut is tightened said first taper is urged into contact with a corresponding inner first taper of said backshell sufficient to urge a first end of each of said split armor grips closer toward a longitudinal axis of said cable and said second taper is urged into contact with a corresponding inner second taper of said retaining sufficient to urge an opposite end of said split armor grips closer toward a longitudinal axis of said cable and wherein each of said split armor grips includes means for engaging said armor cladding disposed on an interior surface thereof.5. The field-attachable, disconnectable electrical connector of claim 1 including means for attaching a certification label thereto.6. The field-attachable, disconnectable electrical connector of claim 1 wherein said sealing grommet is disposed over said plurality of conductors and adjacent to said first end of said housing, and wherein said sealing grommet includes a groove therein that is adapted to permit at least one ground wire to pass through, said ground wire including means for electrical and mechanical connection to said first end of said housing and including a backshell, said backshell including a cylindrical shape and threads adapted to attach a first end of said backshell to said first end of said housing, and wherein said backshell includes an epoxy therein sufficient to fill a first void and wherein said backshell includes a second opposite end and wherein said second opposite end includes second threads, and including a retaining nut that is adapted to cooperate with said second threads sufficient to urge a pair of split armor grips to engage a predetermined amount with an armor cladding of said cable, each of said split armor grips including a substantially cylindrical shape with a first taper at a first end thereof and a second taper at a second end thereof, wherein when said retaining nut is tightened said first taper is urged into contact with a corresponding inner first taper of said backshell sufficient to urge a first end of each of said split armor grips closer toward a longitudinal axis of said cable and said second taper is urged into contact with a corresponding inner second taper of said retaining sufficient to urge an opposite end of said split armor grips closer toward a longitudinal axis of said cable and wherein said retaining nut includes an epoxy therein intermediate said pair of split armor grips and an opposite end of said retaining nut sufficient to fill a second void.7. The field-attachable, disconnectable electrical connector of claim 6 including a portion of cold shrink tubing disposed over a portion of said electrical connector and over a portion of said cable.8. The field-attachable, disconnectable electrical connector of claim 1 wherein said housing includes a radius.9. The field attachable, disconnectable electrical connector of claim 8 wherein said radius includes ninety degrees of arc.10. The field-attachable, disconnectable electrical connector of claim 1 including a power contact pin that is crimped onto each of said plurality of electrical conductors of said cable and a corresponding socket in said first end of said housing, and wherein each of said power contact pins is adapted to connect to one of said corresponding sockets.11. The field-attachable, disconnectable electrical connector of claim 10 including means for latching each of said power contact pins to each of said corresponding sockets sufficient to retain each of said power contact pins in each of said corresponding sockets.12. The field-attachable, disconnectable electrical connector of claim 11 wherein said means for latching each of said power contact pins to each of said corresponding sockets includes a plurality of locking flanges that are disposed circumferentially around a body of each power contact pin and wherein said plurality of locking flanges are adapted to engage with an interior of each of said corresponding sockets.13. The field-attachable, disconnectable electrical connector of claim 1 including a plurality of power pins disposed in said housing, and wherein each of said plurality of power pins is connected electrically at a first end to a portion of said plurality of electrical conductors thereto and wherein each of said plurality of power pins is connected electrically at a second end to a portion of said stationary electrical connector.14.
