Claim 11

A termination assembly comprising a plastic molded support fixture, a plastic molded enclosure and a plastic molded lid, and connecting means for connecting said support fixture, enclosure and lid, said support fixture having a floor having top and bottom surfaces, and at least one open-ended tube depending from said floor bottom surface and opening through said top surface of said floor; said enclosure having a bottom wall, at least one socket wall depending from said bottom wall, said socket wall having an inner surface defining a socket with an open mouth at a lower end thereof of a shape and position complementary to the opening of said tube in said top surface of said support fixture floor, and a knock-out plate forming a closure for said enclosure socket at the upper end thereof, said enclosure having an enclosure skirt extending below a lower surface of said bottom wall and below said socket-defining socket wall, said upper surface of said support fixture floor extending within and being completely surrounded by said enclosure skirt when said enclosure and support fixture are assembled, said support fixture having a support fixture skirt depending from, extending downwardly from and then offset outboardly with respect to said floor to define an enclosure skirt lip-receiving step on its upper surfaces and encompassing said tube with its under surface.

Claim 12

The assembly of claim 9 including a pair of legs integral with said support fixture floor bottom surface and depending therefrom and extending beyond said tube and skirt, said legs being spaced from one another along said bottom surface.

Claim 13

The assembly of claim 10 wherein the skirt is elongatedly rectangular in plan, with side and end walls, the legs are spaced in the lengthwise direction of the side walls, and the lower end of each of said spaced legs has an inverted V-shaped.

Claim 14

The assembly of claim 11 including a strap-receiving bracket positioned symmetrically between said legs in the long dimension of the skirt, said bracket having an elongated strap-receiving opening extending in the direction substantially parallel to the bottom surface of said floor.

Claim 15

The assembly of claim 12 wherein the bracket comprises a metal plate molded into a boss in said support fixture floor lower surface.

Claim 16

A termination assembly comprising a plastic molded cap and a plastic molded pressure plate, said cap having a body with an internal side wall and an internal bottom wall defining a well closed at one end and open at the other, said internal side wall tapering convergently toward said bottom wall, a stepped shelf surrounding said open end of said well at one end of said body and an external flanged base at the other end of said body, said flanged base having an arc of one radius outboard of one side of said body and an arc of a different radius outboard of an opposite side; said pressure plate having a closure body with a flange at one end, said flange having an inside surface defining a receptacle to receive the stepped shelf of the cap and an outside wall having an arc of one radius corresponding to the arc of one radius of said flanged base of said cap and parallel thereto and aligned therewith when the device is assembled and an arc of another radius corresponding to the arc of different radius of said flanged base of said cap and parallel thereto and aligned therewith when the device is assembled, said closure body having an internal wall defining an open-ended socket shaped and positioned at its inner end complementarily to the open end of said cap well and opening at its outer end in a configuration to receive a conductor to be terminated and tapering convergently toward said outer end, and an elastically compressible grommet mounted within said cap and pressure plate, said grommet having a long lower body section tapering convergently complementarily to said cap well and seated therein, and a shorter top body section tapering convergently upwardly complementarily to said pressure plate socket and seated therein, said grommet being of a length and shape to be compressed between said cap and said pressure plate when said cap and pressure plate are assembled.

Claim 17

A termination assembly comprising a plastic molded cap and a plastic molded pressure plate, said cap having a body with an internal side wall and an internal bottom wall defining a well closed at one end and open at the other, said internal side wall tapering convergently toward said bottom wall, a stepped shelf surrounding said open end of said well at one end of said body and an external flanged base at the other end of said body, said flanged base having an arc of one radius outboard of one side of said body and an arc of a different radius outboard of an opposite side; said pressure plate having a closure body with a flange at one end, said flange having an inside surface defining a receptacle to receive the stepped shelf of the cap and an outside wall having an arc of one radius corresponding to the arc of one radius of said flanged base of said cap and parallel thereto and aligned therewith when the device is assembled and an arc of another radius corresponding to the arc of different radius of said flanged base of said cap and parallel thereto and aligned therewith when the device is assembled, said closure body having an internal wall defining an open-ended socket shaped and positioned at its inner end complementarily to the open end of said cap well and opening at its outer end in a configuration to receive a conductor to be terminated and tapering convergently toward said outer end, and an elastically compressible grommet mounted within said cap and pressure plate, said grommet having a long lower body section tapering convergently complementarily to said cap well and seated therein, and a shorter top body section tapering convergently upwardly complementarily to said pressure plate socket and seated therein, said grommet being of a length and shape to be compressed between said cap and said pressure plate when said cap and pressure plate are assembled.
