Abstract:
A receptacle assembly for retaining electric power leads comprising:a pin retainer made of a relatively inflexible, heat resistant nylon having a plurality of orifices therethrough, each shaped to receive an electric power lead and associated pin such that relative rearward movement of said lead is prevented, wherein each of said pin retainer orifices includes a recess, spaced from a periphery of said orifice, forming an annular collar about said power lead pin, each of said collars being shaped to engage an annular rib formed on said power lead pin;a cylindrical backshell having an internal shoulder shaped to seat said pin retainer and prevent relative rearward movement thereof, such that said annular rib is clamped against said collar when a receptacle is connected to said backshell; andsaid receptacle having a housing shaped to threadably engage said backshell, and a grommet of silicone rubber shaped to engage said pin retainer and having a plurality of orifices therethrough, positioned to correspond to said pin retainer orifices when said receptacle is connected to said backshell, and receive said electric power leads, such that, when said receptacle is attached to said pin retainer and said backshell, relative rearward movement of said electric power leads and associated pins is prevented below a predetermined force of approximately 200 pounds (889.6N), and wherein said grommet orifices include constrictions to engage said lead pins, said grommet further including annular recesses positioned to engage and capture said annular ribs, and annular protruding ridges shaped to engage said pin receptacle orifice recesses; andwherein said receptacle housing is shaped to engage said backshell such that such engagement clamps said pin retainer against said grommet.
