Abstract
Abstract A connector having a plug housing and a receptacle housing, each having apertured mounting projections on the end walls thereof for mounting the housings to printed circuits and motherboards, respectively, by means of a bolt and nut associated with each projections; and key means including matching planar key tabs and polygonal mounting tabs configured to nestle within a polygonal cutout on the housing projections, these mounting tabs being apertured to receive a mounting bolts so that the keys are secured to the housings and do not protrude beyond the side walls of the housings.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
293 words
An electrical connector assembly comprising: an elongate first connector portion having first and second sidewalls, a top wall and first and second end walls, each having connector-securing projections extending from said end walls, said projections being apertured to receive a mounting bolt with a cutout at respective ends of said aperture for receiving a mounting nut; a second connector portion operable to mate with said first connector portion and having first and second walls, a bottom wall, and first and second end walls each having a connector-mounting projection extending from said end walls, said projections being apertured to receive a mounting bolt and having a cutout for receiving a nut at one end of said aperture; first electrical contact means disbursed in said first connector portion; second electrical contact means disbursed in said second connector portion and being operable to mate with said first electrical contact means when said first connector portion is mated with said second connector portion; and detachable pairs of key means being configured to match the surface contour of said mounting projections and each being apertured to receive the mounting bolt to fasten said key means to said projections, each of said pairs of detachable keys having a planar keying tab which is registered to operably pass by the other key tab of said pair when a match occurs and to contact each other and prevent mating of said first and second connector portions with a mismatch occurs between a pair of key means and wherein said key means each include a mounting tab which is configured to fit within said nut mounting cutout and said mounting tab is apertured in axial alignment with the aperture in said projection when said mounting tab is nested in said nut-receiving cutout.

An electrical connector assembly comprising: an elongate first connector portion having first and second sidewalls, a top wall and first and second end walls, each having connector-securing projections extending from said end walls, said projections being apertured to receive a mounting bolt with a cutout at respective ends of said aperture for receiving a mounting nut; a second connector portion operable to mate with said first connector portion and having first and second walls, a bottom wall, and first and second end walls each having a connector-mounting projection extending from said end walls, said projections being apertured to receive a mounting bolt and having a cutout for receiving a nut at one end of said aperture; first electrical contact means disbursed in said first connector portion; second electrical contact means disbursed in said second connector portion and being operable to mate with said first electrical contact means when said first connector portion is mated with said second connector portion; and detachable pairs of key means being configured to match the surface contour of said mounting projections and each being apertured to receive the mounting bolt to fasten said key means to said projections, each of said pairs of detachable keys having a planar keying tab which is registered to operably pass by the other key tab of said pair when a match occurs and to contact each other and prevent mating of said first and second connector portions with a mismatch occurs between a pair of key means and wherein said key means each include a mounting tab which is configured to fit within said nut mounting cutout and said mounting tab is apertured in axial alignment with the aperture in said projection when said mounting tab is nested in said nut-receiving cutout.
Claim 3
Dependent Claim
15 words
The electrical connector assembly of claim 1 in which said keying tabs are substantially rectilinear.
Claim 4
Dependent Claim
35 words
The electrical connector assembly of claim 1 in which said keying tabs are disposed in planes which are substantially parallel to the planes of said end walls of said first and said second connector portions.
Claim 5
Dependent Claim
36 words
The electrical connector assembly of claim 1 in which said keying tabs are oriented in planes which are at a right angle to the planes of said end walls of said first and second connector portions.
Claim 6
Dependent Claim
26 words
The electrical connector assembly of claim 1 in which said mounting tab is configured in a polygon, conforming to the polygonal configuration of the mounting nut.
Claim 7
Dependent Claim
24 words
The electrical connector assembly of claim 1 in which the aperture of one of said pairs of said key means include a threaded insert.
Claim 8
Dependent Claim
56 words
The electrical connector assembly of claim 1 in which each one of said key means of said pairs of key means when attached to the projections is disposed in a space defined generally by the planes of side walls, said top walls and said bottom walls of said first connector portion and said second connector portion.
Claim 9
Dependent Claim
15 words
The electrical connector assembly of claim 1 in which said nut receiving cutout is polygonal.
Claim 10
Dependent Claim
20 words
The electrical connector assembly of claim 8 in which said nut receiving cutout is polygonal to receive to hexagonal nut.
Claim 11
Dependent Claim
71 words
The electrical connector assembly of claim 1 in which one of said key means each of said pairs of key means has a stop member which is operable to contact the surface of said projection and the other of said key means of each of said pair of key means includes an alignment tab operable to contact the surface of projection on the other of said first and second connector portions.
Claim 12
Dependent Claim
35 words
The connector assembly of claim 10 in which the adjacent side walls of said keying tabs of said key pairs operable pass by each other without contact when a match occurs between that key pair.
