SURFACE MOUNT KEYHOLE CONNECTORS

摘要

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.

1. A surface mount electrical keyhole connector comprises a generally flat mounting portion suitable for surface mounting on a printed circuit board (PCB) and at least one contact portion 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 d1 surrounded by an outer insulation coating generally defining a diameter d2 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 d1, 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; and retaining means for retaining a conductor forced into said downstream elongated slot to prevent an insulated conductor from moving upstream back into said upstream open region, 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.
