Electrical connector assembly for a refrigerator door
First Claim
1. An electrical connector assembly comprising:
- a plug subassembly including;
an insulative plug body having a hollow forward mating portion bounded by a cylindrical wall defining a longitudinal plug axis and subtending an arc greater than 180° and
less than 360°
to provide a gap in said cylindrical wall, the plug body further having a contact receiving portion rearwardly of said gap, said contact receiving portion being a substantially solid partial cylinder coextensive with said cylindrical wall and subtending an arc greater than 180° and
less than the arc subtended by the cylindrical wall to provide a planar surface rearwardly of said gap and angularly symmetrical about said axis with respect to said gap, said contact receiving portion being formed with at least one contact receiving bore extending longitudinally therethrough from a rear wall to a front mating wall defining the rear of said forward mating portion;
at least one conductive male contact member received in a respective one of said at least one contact receiving bore and having a forward mating end extending beyond said front mating wall into said forward mating portion; and
a latch member mounted to said planar surface and pivotable about a pivot axis orthogonal to said plug axis, said latch member having a forward end with a rear engagement wall extending into said gap; and
a receptacle subassembly including;
an insulative receptacle body having a substantially cylindrical shape defining a longitudinal receptacle axis and sized so that a forward portion fits within said forward mating portion of said plug body with the receptacle axis being parallel to the plug axis, said receptacle body being formed with at least one contact receiving bore extending longitudinally therethrough from a rear wall to a front mating wall and aligned with a respective one of said plug body at least one contact receiving bore when said receptacle body is received in said plug body forward mating portion;
at least one conductive female contact member received in a respective one of said receptacle body at least one contact receiving bore and having a forward mating end adapted for mating engagement with the forward mating end of a respective plug male contact member, the forward mating end of said at least one female contact member being recessed within its respective bore behind said receptacle front mating wall; and
an abutment extending radially outward from said receptacle body forward portion, said abutment extending into said gap when said receptacle body forward portion is received in said plug body forward mating portion, said abutment having a rear wall adapted for interfering engagement with the rear engagement wall of said plug latch member when said receptacle body forward portion is fully seated in said plug body forward mating portion.

Abstract
An electrical connector assembly which includes a plug subassembly and a receptacle subassembly. The receptacle subassembly is substantially cylindrical with a diameter such that it passes through the hollow hinge pin of a refrigerator door. The receptacle body is formed with an outwardly extending abutment which is confined to the diametrical extremity of the cylinder and which cooperates with a latch member of the mating subassembly. The plug subassembly has a hollow forward mating portion for accepting the receptacle body therein. The forward mating portion is formed by an incomplete cylindrical wall having a longitudinal gap. The receptacle abutment is aligned with the gap and the plug latch member extends into the gap. Polarizing features are provided on both the plug and receptacle bodies to insure appropriate alignment of the plug and receptacle subassemblies.

9. An electrical connector subassembly comprising:
-
an insulative body having a hollow forward mating portion bounded by a cylindrical wall defining a longitudinal axis, the body further having a contact receiving portion which is substantially solid and coextensive with at least part of said cylindrical wall, said contact receiving portion being formed with at least one contact receiving bore extending longitudinally therethrough from a rear wall to a front mating wall defining the rear of said forward mating portion; at least one conductive contact member received in a respective one of said at least one contact receiving bore of said body and having a forward mating end extending beyond said front mating wall into said hollow forward mating portion; and at least one raised longitudinal rib within said hollow forward mating portion to provide a polarizing feature in cooperation with a complemental groove on the exterior of an insulative body of a complemental mating connector subassembly received in said hollow forward mating portion, the forward end of said at least one rib being recessed within said hollow forward mating portion whereby said insulative bodies of said complemental mating connector subassemblies are partially mated before polarization and subsequent mating of complemental contact members within said subassemblies.
