Claim 13

An electrical connector comprising: an insulator having a front face and a rear face with a contact cavity therein extending from said front face to said rear face; said cavity having a top, a bottom and a pair of sides; a projection in one corner of said cavity joined to said top and one side thereof, said projection providing a forwardly facing shoulder; an electrical contact mounted in said cavity, said contact comprising an electrically conductive body having a forward section and a generally U-shaped retention section behind said forward section; said retention section having a generally flat elongated base lying on said bottom of said cavity and first and second upstanding sidewalls adjacent to said one side and the other side, respectively, of said cavity; a spring retention tine formed from said second sidewall extending rearwardly and inwardly toward said one side with the end of said tine engaging said shoulder to restrict rearward movement of said contact in said cavity; and said first sidewall blocking said tine from extending outwardly beyond the perimeter of said U-shaped retention section and being sufficiently short so as to pass under said projection when said contact is inserted into said cavity from said rear face of said insulator.
