Claim 2

An electrical connector comprising: an insulating housing comprising a mating face and a rear face and including a plurality of electrical contacts disposed in said housing, said plurality of electrical contacts being adapted to extend from at least said rear face to at least said mating face, said insulating housing further including two sockets positioned in spaced-apart relation on lateral sides of said insulating housing, said sockets each including a contact receiving cavity positioned within an inboard portion of said socket; and an electrostatic discharge contact located within each of said contact receiving cavities, each said electrostatic discharge contact comprising; a proximal portion and a distal portion and having a substantially flat outside and a substantially flat inside surface extending therebetween; retention dimples disposed in spaced-apart relation on said proximal portion of said outside surface, said retention dimples being adapted to engage a corresponding surface in a receiving cavity in an insulating housing; and an arm extending away from said proximal portion, said arm including a rounded distal end adapted to electrically engage a portion of a board mount disposed in said insulating housing.

Claim 3

An electrical connector according to claim 1 wherein said board mount comprises: a web having a first edge defining a periphery of a mounting post and a first flange extending in transverse coplanar relation to said mounting post, said first flange being adapted for engaging a circuit board; a second edge on said web defining a second flange turned out from the plane of said web, said second flange extending in transverse relation to said mounting post, said second flange extending over said mounting post so as to provide a force receiving pressure plate on which an insertion force is applied to insert said mounting post in an aperture of a circuit board; and an anchor fluke connected to said web for fastening said board mount in said insulating housing, a portion of said anchor fluke being disposed in electrical engagement with said arm.

Claim 4

An electrical connector assembly comprising: a first electrical connector comprising: an insulating housing having a mating face for connection with a second mating electrical connector; a plurality of electrical contacts disposed in said insulating housing and extending from a rear face toward said mating face; insulating posts disposed in spaced-apart relation on the lateral sides of said insulating housing and further comprising conductive ground contacts extending along said insulating posts, said posts and said ground contacts projecting outwardly beyond said mating face to establish a ground connection of said ground contacts with said second mating electrical connector at a location spaced apart from said mating face, and to align said mating face while said mating face is spaced apart from said second mating electrical connector; and said second mating electrical connector comprising: an insulating housing comprising a mating face and a rear face and including a plurality of electrical contacts disposed in said housing, said plurality of electrical contacts being adapted to extend from at least said rear face to at least said mating face, said insulating housing further including two sockets positioned in spaced-apart relation on lateral sides of said insulating housing, said sockets each including a contact receiving cavity positioned within an inboard portion of said socket; and an electrostatic discharge contact located within each of said contact receiving cavities, each said electrostatic discharge contact comprising; a proximal portion and a distal portion and having a substantially flat outside and a substantially flat inside surface extending therebetween; retention dimples disposed in spaced-apart relation on said proximal portion of said outside surface, said retention dimples being adapted to engage a corresponding surface in a receiving cavity in an insulating housing; and an arm extending away from said proximal portion, said arm including a rounded distal end adapted to electrically engage a portion of a board mount disposed in said insulating housing.

Claim 5

An electrical connector assembly comprising: a first electrical connector comprising: an insulating housing having a mating face for connection with a second mating electrical connector; a plurality of electrical contacts disposed in said insulating housing and extending from a rear face toward said mating face; insulating posts disposed in spaced-apart relation on the lateral sides of said insulating housing and further comprising conductive ground contacts extending along said insulating posts, said posts and said ground contacts projecting outwardly beyond said mating face to establish a ground connection of said ground contacts with said second mating electrical connector at a location spaced apart from said mating face, and to align said mating face while said mating face is spaced apart from said second mating electrical connector; and said second mating electrical connector comprising: an insulating housing comprising a mating face and a rear face and including a plurality of electrical contacts disposed in said housing, said plurality of electrical contacts being adapted to extend from at least said rear face to at least said mating face, said insulating housing further including two sockets positioned in spaced-apart relation on lateral sides of said insulating housing, said sockets each including a contact receiving cavity positioned within an inboard portion of said socket; and an electrostatic discharge contact located within each of said contact receiving cavities, each said electrostatic discharge contact comprising; a proximal portion and a distal portion and having a substantially flat outside and a substantially flat inside surface extending therebetween; retention dimples disposed in spaced-apart relation on said proximal portion of said outside surface, said retention dimples being adapted to engage a corresponding surface in a receiving cavity in an insulating housing; and an arm extending away from said proximal portion, said arm including a rounded distal end adapted to electrically engage a portion of a board mount disposed in said insulating housing.

Claim 6

An electrical connector assembly according to claim 3 wherein said first electrical connector further comprises inwardly facing surfaces on said posts and having said ground contacts disposed along said inwardly facing surfaces of said posts.

Claim 7

An electrical connector assembly according to claim 3, wherein said board mount comprises: a web having a first edge defining a periphery of a mounting post and a first flange extending in transverse coplanar relation to said mounting post, said first flange being adapted for engaging a circuit board; a second edge on said web defining a second flange turned out from the plane of said web, said second flange extending in transverse relation to said post, said second flange extending over said post so as to provide a force receiving pressure plate on which an insertion force is applied to insert said post in an aperture of a circuit board; and an anchor fluke connected to said web for fastening said board mount in said insulating housing, said anchor fluke disposed in electrical engagement with said arm.

Claim 8

An electrical connector assembly according to claim 5 further wherein said plurality of electrical contacts and said ground contacts in said first electrical connector are arranged so that said ground contacts extend beyond said mating face and are longer than said electrical contacts, and further wherein said insulating posts partially surround portions of said ground contacts, with said ground contacts projecting outwardly beyond said mating face to engage said electrostatic discharge contacts of said second mating electrical connector while said posts engage said sockets.

Claim 9

An electrical connector assembly according to claim 5 wherein said plurality of electrical contacts in said first electrical connector engage said corresponding plurality of electrical contacts in said second mating electrical connector subsequent in sequence to engagement of said ground contacts and said electrostatic discharge contacts.
