Abstract
Abstract An electrical connector includes a male plug having preferably two tapered major surfaces and a female receptacle having walls corresponding in taper to the major surfaces of the male plug. The male plug is adapted to terminate a ribbon cable and may be formed by a tapered circuit board or a tapered form around which conductors of a ribbon cable are bent. The female receptacle is lined with a flexible circuit for contact to the male plug and connection to a circuit board.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
219 words
An electrical connector comprising: a male connector half terminating in a plug end having a vertical axis and two major surfaces wherein at least one of said major surfaces is a tapered surface disposed at an acute angle to said vertical axis; a female connector half having walls defining a receptacle for said male connector half and a vertical axis parallel to said male connector half vertical axis wherein one of said walls is a tapered wall disposed at an angle to said female connector half vertical axis corresponding to said acute angle of said male connector half tapered surface; at least said male tapered surface and at least said female tapered wall each including corresponding individual electrical contact traces lying in planes parallel to said male tapered surface and said female tapered side wall, respectively, for making electrical contact between said male connector half and said female connector half when said connector halves are mated so as to force said male tapered surface and said female tapered wall together; and wherein said male connector half terminates an electrical cable comprising a series of parallel conductors encapsulated in an electrically insulating sheath, said tapered surface includes a series of parallel grooves, and said electrical contact traces are exposed conductors of said cable disposed one each in a said groove.
Claim 2
Dependent Claim
219 words
An electrical connector comprising: a male connector half terminating in a plug end having a vertical axis and two major surfaces wherein at least one of said major surfaces is a tapered surface disposed at an acute angle to said vertical axis; a female connector half having walls defining a receptacle for said male connector half and a vertical axis parallel to said male connector half vertical axis wherein one of said walls is a tapered wall disposed at an angle to said female connector half vertical axis corresponding to said acute angle of said male connector half tapered surface; at least said male tapered surface and at least said female tapered wall each including corresponding individual electrical contact traces lying in planes parallel to said male tapered surface and said female tapered side wall, respectively, for making electrical contact between said male connector half and said female connector half when said connector halves are mated so as to force said male tapered surface and said female tapered wall together; and wherein said male connector half terminates an electrical cable comprising a series of parallel conductors encapsulated in an electrically insulating sheath, said tapered surface includes a series of parallel grooves, and said electrical contact traces are exposed conductors of said cable disposed one each in a said groove.
Claim 3
Dependent Claim
50 words
An electrical connector according to claim 1 wherein said male connector half includes one tapered major surface and an opposite vertical major surface parallel to said vertical axis of said male connector half and said female connector half includes a vertical wall corresponding to said male connector half vertical surface.
Claim 4
Dependent Claim
28 words
An electrical connector according to claim 2 wherein both major surfaces of said male connector half and corresponding walls of said female connector half include electrical contact traces.
Claim 5
Dependent Claim
44 words
An electrical connector according to claim 1 wherein both major surfaces of said male connector half and corresponding walls of said female connector half are tapered surfaces inclined at opposite but equal acute angles with respect to said vertical axes of said connector halves.
Claim 6
Dependent Claim
28 words
An electrical connector according to claim 4 wherein both major surfaces of said male connector half and corresponding walls of said female connector half include electrical contact traces.
Claim 7
Dependent Claim
42 words
An electrical connector according to claim 1 wherein said female connector half includes a flexible circuit overlying a wall of said female connector half and defining said contact traces, said flexible circuit including a polymeric backing and electrically conductive pathways attached thereto.
Claim 8
Dependent Claim
35 words
An electrical connector according to claim 6 wherein said female connector half further includes a resilient member disposed between said flexible circuit and said wall of said female connector half which said flexible circuit overlies.
