Miniature electrical connector

Claim 2

A one-piece housing for an edge connector for a circuitry board or the like, said housing comprising a body portion formed of a dielectric material, a plurality of regularly spaced apertures disposed in said body portion, said apertures being of cylindrical configuration for receiving complementary-shaped electrical contacts, abutment means disposed within said body portion for limiting the extent of contact insertion within said apertures, a generally rectangular opening extending along said housing for receiving an edge of a circuitry board, said apertures and said opening being disposed along opposite side faces of said housing, constructed passageways extending between said apertures and said rectangular opening for receiving contact tab portions, shoulder means disposed at the intersection of said passageways and said rectangular opening, and camming means disposed within said passageways between said abutment means and said shoulder means for camming the contact tab portions into engagement with said shoulder means for preventing withdrawal of the contacts.

Claim 3

A one-piece housing as set forth in claim 1 further comprising a plurality of grooves disposed in parallel relation along said rectangular opening for receiving the contact tab portions.

Claim 4

A one-piece housing as set forth in claim 1 wherein said apertures are disposed along two parallel rows and wherein the apertures in one row are staggered in relation to the apertures in the second row.

Claim 5

An electrical connector for a circuitry board or the like comprising a housing formed of a dielectric material and having a plurality of regularly spaced apertures disposed therein, said apertures being of generally cylindrical configuration and being disposed along a first side face of said housing, a generally rectangular opening disposed in said housing and lying along a second side face of said housing opposite to said first side face for receiving a circuitry board, a plurality of electrical contacts disposed respectively in said plurality of apertures and being of complementary shape therewith and insertable from said first side face of said housing, means integral with said housing for preventing said contacts from being insertable from said second side face of said housing, a constricted passageway in said housing for joining each said aperture with said opening, tab means extending from each said contact and having an undulation adjacent the contact passing through said passageway for connection with said circuit board, shoulder means disposed at the intersection of said passageways and said rectangular opening, means mounting the tabs with a segment of the undulation in contact with the shoulder means and passageway to hold said tab means in engagement with said shoulder means for preventing withdrawal of said contacts from said apertures.

Claim 6

An electrical connector for a circuitry board or the like comprising a housing formed of a dielectric material and having a plurality of regularly spaced apertures disposed therein, said apertures being of generally cylindrical configuration and being disposed along a first side face of said housing, a generally rectangular opening disposed in said housing and lying along a second side face of said housing opposite to said first side face for receiving a circuitry board, a plurality of electrical contacts disposed respectively in said plurality of apertures and being of complementary shape therewith and insertable from said first side face of said housing, means integral with said housing for preventing said contacts from being insertable from said second side face of said housing, a constricted passageway in said housing for joining each said aperture with said opening, tab means extending from each said contact and having an undulation adjacent the contact passing through said passageway for connection with said circuit board, shoulder means disposed at the intersection of said passageways and said rectangular opening, means mounting the tabs with a segment of the undulation in contact with the shoulder means and passageway to hold said tab means in engagement with said shoulder means for preventing withdrawal of said contacts from said apertures.

Claim 7

An electrical connector as set forth in claim 4 wherein said contacts comprise female receptacles for receiving pin members.

Claim 8

An electrical connector as set forth in claim 4 wherein said contacts comprise male pin members for insertion in receptacles.

Claim 9

An electrical connector as set forth in claim 4 wherein said apertures are disposed along two parallel rows and wherein the apertures in one row are staggered in relation to the apertures in a second row.

Claim 10

An electrical connector as set forth in claim 7 wherein said tab means extending from one row of said contacts are disposed along a first side of said rectangular opening and wherein said tab means extending from a second row of said contacts are disposed along a second side of said rectangular opening.

Claim 11

An electrical connector as set forth in claim 7 wherein said tab means extending from both rows of electrical contacts are disposed along the same side of said rectangular opening.
