Abstract:
1. A surface mount electrical keyhole connector comprises a generally flat mounting portion suitable for surface mounting on a printed circuit board (PCB) and two contact portions that are generally parallel to each other and generally normal or perpendicular to said flat mounting portion, said at least one flat contact portion being provided with an aperture generally in a shape of a keyhole that defines a longitudinal axis and includes an upstream open region dimensioned to receive with clearance an insulated conductor having a metallic conductor generally having a diameter d 1 surrounded by an outer insulation coating generally defining a diameter d 2 and a downstream elongated slot formed by generally parallel opposing edges substantially parallel to said axis of symmetry and spaced from each other a distance h that is less than said diameter d 1 , said generally circular and opposing edges meeting at intermediate transitions points where said enlarged upstream open region transitions with said downstream elongated slot, said edges at said transition points forming insulation cutting means for cutting or stripping insulation off an insulated conductor, said opposing edges of said elongated slot downstream of said transition points serving to make positive contact with the conductive wire or wires within an insulated conductor after the conductor is urged downstream into and is fully seated within said elongated slot, wherein said mounting portion is split along its longitudinal length to break electrical continuity between said two contact portions.
