Abstract
Abstract Two dielectric housings are mounted respectively to printed circuit boards. When the housings are mated together the two printed circuit boards will be connected electrically together with pins on the one board within receptacles of the other board. One of the housings is connected to an edge margin of the board and is provided with a chamfered lip which covers the edge of the board and provides a polarizing structure to permit interconnection between the two housings when oriented as desired.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
208 words
A polarized connector, comprising: a first connector housing mounted on a printed circuit board and having a plurality of pins therein, an opening in said first connector housing encircled by chamfered edges defining a funnel entry, a second connector housing having a plurality of receptacles therein for receiving in mating engagement said pins, said second connector housing being mounted on an edge margin of a printed circuit board, a lip on said second connector housing flush with one end thereof and covering an edge of said printed circuit board, said lip and said one end of said second connector housing being chamfered on the peripheral edges thereof for ease in insertion within said funnel entry, said pins being arranged in rows within said first connector housing offset toward a side of said first connector housing, said receptacles being arranged in rows within said second connector housing and including tail portions projecting therefrom for mounting within said printed circuit board, said receptacles being of different distances from said one end of said second connector housing, said pins being received through said one end of said second connector housing, and said receptacles being sequentially received over corresponding pins during insertion of said second connector housing in said first connector housing.
Claim 2
Dependent Claim
208 words
A polarized connector, comprising: a first connector housing mounted on a printed circuit board and having a plurality of pins therein, an opening in said first connector housing encircled by chamfered edges defining a funnel entry, a second connector housing having a plurality of receptacles therein for receiving in mating engagement said pins, said second connector housing being mounted on an edge margin of a printed circuit board, a lip on said second connector housing flush with one end thereof and covering an edge of said printed circuit board, said lip and said one end of said second connector housing being chamfered on the peripheral edges thereof for ease in insertion within said funnel entry, said pins being arranged in rows within said first connector housing offset toward a side of said first connector housing, said receptacles being arranged in rows within said second connector housing and including tail portions projecting therefrom for mounting within said printed circuit board, said receptacles being of different distances from said one end of said second connector housing, said pins being received through said one end of said second connector housing, and said receptacles being sequentially received over corresponding pins during insertion of said second connector housing in said first connector housing.
Claim 3
Dependent Claim
221 words
A polarized connector, comprising: a first connector housing mounted on a printed circuit board and having a plurality of pins therein, an opening in said first connector housing encircled by chamfered edges defining a funnel entry, a second connector housing having a plurality of receptacles therein for receiving in mating engagement said pins, said second connector housing being mounted on an edge margin of a printed circuit board, a lip on said second connector housing flush with one end of said second connector housing and covering an edge of said printed circuit board, said lip and said one end being chamfered on the peripheral edges thereof for ease in insertion within said funnel entry, said pins being arranged in rows within said first connector housing offset toward a side of said first connector housing, said receptacles being arranged in rows within said second connector housing and including tail portions projecting therefrom for mounting within said printed circuit board, said second connector housing including a slotted opening communicating with the receptacles arranged in rows, and said second connector housing including a recess intersecting said receptacles of one of said rows, whereby an extraction tool may enter said recess and project into said slotted opening to deflect a portion of a selected receptacle and thereby allow removal thereof from said second connector housing.
