Abstract
Abstract A tractor-trailer electrical receptacle is disclosed wherein a housing contains a cavity having a plurality of male contact members mounted therein; the cavity is adapted for receiving a mating electrical plug. A mounting member connected to the housing is adapted for mounting the housing at an angle inclined to the horizontal to promote drainage of any moisture in the cavity away from the contact members. A support member extends forwardly from the housing to provide such support for an electrical plug mated with the receptacle as minimizes the effects of vehicle vibration upon such plug. A cover is connected to said housing and urged by a spring to close the cavity when a plug is not inserted in the receptacle.

Claim 1
Independent Claim
64 words
An electrical receptacle comprising a housing including a cavity therein having a principal axis, contact means mounted at least partially within said cavity, said housing having a first end and said cavity being open at said first end, said first end of said housing having a substantially planar end surface at an angle significantly other than 90° to said principal axis of said cavity.
Claim 2
Dependent Claim
64 words
An electrical receptacle comprising a housing including a cavity therein having a principal axis, contact means mounted at least partially within said cavity, said housing having a first end and said cavity being open at said first end, said first end of said housing having a substantially planar end surface at an angle significantly other than 90° to said principal axis of said cavity.
Claim 3
Dependent Claim
55 words
An electrical receptacle as in claim 1 further comprising mounting means connected to said housing, said mounting means being adapted to mount said housing on a vertical member with said principal axis inclined to the horizontal; and wherein said contact means comprise a plurality of contact members mounted in said housing rearwardly of said cavity.
Claim 4
Dependent Claim
19 words
An electrical receptacle as in claim 2 further comprising a cover for said open cavity at said first end.
Claim 5
Dependent Claim
41 words
An electrical receptacle as in claim 3 further comprising spring means for urging said cover to close said opening of said cavity; and wherein said substantially planar first end includes an annular groove and said cover includes a mating annular rib.
Claim 6
Dependent Claim
43 words
An electrical receptacle according to claim 1 further comprising cover means for covering said open end of said cavity at said first end, said cover means including an annular rib and said end surface including an annular groove for receiving said annular rib.
Claim 7
Dependent Claim
33 words
An electrical receptacle according to claim 5 wherein said cavity is of substantially cylindrical form; and further comprising mounting means adapted for mounting said housing with said principal axis inclined to the horizontal.
Claim 8
Dependent Claim
96 words
An electrical receptacle comprising a housing having a cavity therein, said cavity having a principal axis and being open on one end of said housing, electrical contact means mounted in said housing, cover means rotatably mounted about a rotation axis at said one end of said housing, said housing including a support portion extending toward said one end substantially beyond a plane perpendicular in two directions to said principal axis and passing through the opening of said cavity, said support portion being adapted to provide support to a plug which may be mated with said receptacle.
Claim 9
Dependent Claim
96 words
An electrical receptacle comprising a housing having a cavity therein, said cavity having a principal axis and being open on one end of said housing, electrical contact means mounted in said housing, cover means rotatably mounted about a rotation axis at said one end of said housing, said housing including a support portion extending toward said one end substantially beyond a plane perpendicular in two directions to said principal axis and passing through the opening of said cavity, said support portion being adapted to provide support to a plug which may be mated with said receptacle.
Claim 10
Dependent Claim
35 words
