Abstract
Abstract A connector assembly is disclosed for effecting zero insertion force mating of projecting blade portions of terminals carried by a plug member with conductive holes in a circuit board or the like and enclosed in a header. The plug member has a housing, a plurality of terminals carried in the housing each with a blade portion projecting from a mating face and a conductor engaging portion, and hermaphroditic cover members enclosing a portion of the housing. The housing also has a cam surface and polarizing lugs. The header has means to mount it on a circuit board or the like with walls of the header forming a shroud around an array of conductive holes in the circuit board. A cam member is rotatably mounted in one end of the header to act on the plug member driving it transversely to bring the blades of the terminals into contact with the walls of the respective conductive holes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
163 words
A low entry force electrical connector system for making interconnection with an array of conductive holes of a circuit board or the like, comprising: a plug assembly having a housing with a mating face and a plurality of terminals mounted in said housing each with a beam portion extending beyond said mating face; a header assembly having means to mount said header assembly on a circuit board and spaced walls defining a plug receiving cavity enclosing an array of conductive holes in said circuit board, cam means mounted in one end of said header assembly adapted to act on said plug assembly whereby when said plug assembly is initially engaged in said header assembly said beam portions extend at least partially into each respective conductive hole in said circuit board and upon actuation of said cam means said plug assembly is driven transversely with respect to said header assembly to bring said beam portions into engagement with walls of the respective conductive holes.
Claim 2
Dependent Claim
163 words
A low entry force electrical connector system for making interconnection with an array of conductive holes of a circuit board or the like, comprising: a plug assembly having a housing with a mating face and a plurality of terminals mounted in said housing each with a beam portion extending beyond said mating face; a header assembly having means to mount said header assembly on a circuit board and spaced walls defining a plug receiving cavity enclosing an array of conductive holes in said circuit board, cam means mounted in one end of said header assembly adapted to act on said plug assembly whereby when said plug assembly is initially engaged in said header assembly said beam portions extend at least partially into each respective conductive hole in said circuit board and upon actuation of said cam means said plug assembly is driven transversely with respect to said header assembly to bring said beam portions into engagement with walls of the respective conductive holes.
Claim 3
Dependent Claim
33 words
The electrical connector system according to claim 1 further comprising: polarizing means on said plug assembly and said header assembly permitting only a unidirectional mating of said plug assembly and said header assembly.
Claim 4
Dependent Claim
34 words
The electrical connector system according to claim 1 further comprising: cam abutment means on one end of said plug assembly which abutment is engaged by said cam means to drive said plug assembly transversely.
Claim 5
Dependent Claim
42 words
The electrical connector system according to claim 1 further comprising: mounting legs depending from said header assembly and engagable in mounting apertures in said circuit board adjacent said array of conductive holes to securely mount said header assembly on said circuit board.
Claim 6
Dependent Claim
41 words
The electrical connector system according to claim 1 wherein said cam means comprises: a first driving surface acting against said plug assembly, and a second profiled flange portion guided by said header assembly to limit the rotary movement of said cam.
Claim 7
Dependent Claim
72 words
An electrical connector system according to claim 1 wherein said header assembly further comprises: a cam receptacle having an arcuate wall and a pair of lugs spaced inwardly of said arcuate wall defining an arcuate slot therebetween, an annular recess in said cam means, an inwardly directed shoulder on a free end of each said lug engageable in said annular recess whereby movement of said cam means is limited to rotary only.
