An electrical connector having an electrically non-conductive carrier, the carrier having a plurality of contact pin mounting holes extending there through. Each hole has a square cross-section. An electrically conductive contact pin is passed through each hole. Each contact pin has a generally cylindrical shape with a leading pin section, a trailing pin section, and a contact head at the end of the trailing pin section. A retainer is provided on the pin separating the leading pin section from the trailing pin section. The trailing pin section has a length slightly longer than the length of the hole and a diameter slightly less than the width of the hole. The retainer and the contact head both have a diameter at least slightly greater than the width of the hole to retain the pin in the hole. An electrical contact pin for use with a multi pin electrical connector adapted to be surface mounted on a printed circuit board. The contact pin is generally cylindrical in shape and has a leading pin section, a trailing pin section, and a retainer integral with the pin and located between the leading pin section and the trailing pin section. A contact head is provided at the free end of the trailing pin section. The retainer is in the form of a collar with a leading conical portion adjacent the leading pin section and a trailing cylindrical portion adjacent the trailing pin section. A method of inserting an electrically conductive, cylindrical, contact pin into a square hole on a non-electrically conductive carrier, the contact pin having a leading pin section with at least a portion having a diameter slightly greater than the width of the hole and a retainer behind the leading pin section having a diameter greater than the diameter of the portion of the leading pin section. The method comprises pushing the leading pin section into and through the hole to initially deform the hole, and continuing to push the pin to move the retainer through the hole to complete deformation of the hole to be able to pass the retainer through the hole.
