An SMT electrical keyhole connector includes a flat mounting portion for surface mounting on a PCB and two spaced contact portions each provided with an aperture in a shape of a keyhole that defines a longitudinal insertion axis and includes an upstream open region dimensioned to receive with clearance an insulated conductor having a metallic conductor generally having a diameter d1 surrounded by an outer insulation coating generally defining a diameter d2 and a downstream elongated slot formed by parallel opposing edges spaced from each other a distance h less than d1. Cutting edges cut or strip insulation off an insulated conductor. A retainer prevents a stripped conductor from moving upstream back into the open region to insure positive contact with the conductive wire or wires after the conductor is urged downstream into and is fully seated within the elongated slot.
