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 dsurrounded by an outer insulation coating generally defining a diameter dand a downstream elongated slot formed by parallel opposing edges spaced from each other a distance h less than d. 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.

Surface mount keyhole connectors

A surface mount insulation terminal is formed of flat deformable conductive member to provide a substantially uniform U-shaped cross-section to form a wire-receiving channel. One or more piercing spikes are formed on a bottom wall of the channel and point to an opposing open side through which a conductor may be introduced. Ribs inside the channel provide an interference fit with a conductor introduced into the channel. A crimping tool lowered into engagement with the terminal after it has been soldered to a PCB increasingly deforms the side walls of the terminal inwardly towards each other and towards the bottom wall to enhance the electrical and mechanical properties of the resulting termination.

There is provided an insulation displacement connector (IDC) assembly having a main body defining at least one wire channel. The main body has at least one substantially flat surface to which a vacuum nozzle can be affixed in order to pickup the IDC assembly. The IDC assembly has at least one contact member with a piercing, cutting or slicing end that is slideably disposed within the main body, and a mounting end that extends from the main body. The mounting end of the contact is attached to a printed circuit board. An insulated conductor, such as wire, cable, and/or ribbon, can be quickly and easily inserted in the channel without being pierced by the piercing end of the contact. When a user pushes down on the IDC, the contact slides into the channel and pierces the insulated conductor.

There is provided a feeder device for a pick-and-place machine used to surface mount connectors on printed circuit boards. The feeder is designed for use with matrixes of connectors, such as pin headers. The feeders, with the proper conversion kits, can be configured to feed any type and/or size of the connector. Individual connectors are separated from the matrix by the feeder using a rotating clamping device. Preferably, the feeders are microprocessor controlled, use an edge conveyor to transport the strips to the pick point, and pneumatic cylinders to break each pin header from the strip.

One and two piece surface mount pin constructions include excess solder receiving channels. In the one piece construction an elongate channel is provided through a tubular pin which is flared or swaged at the lower end to form a base. In the two piece construction a solid pin is provided at a lower end with a uniform cross section in the form of a regular polygon, such as a square, hexagon or octagon. The resulting edges are press-fit against an internal surface of a sleeve which is also swaged at a lower end to form a base. The spaces between the sleeve and the flat or convex surfaces on the captured end of the pin provide the solder-receiving channels. A bead or shoulder on the pins can provide a stop for a vacuum nozzle. When a flared upper lip is used for this purpose it can also serve as a reservoir or well to receive excess solder beyond the amount that can be received in the channels.
