Abstract: An electrical connector assembly comprising a socket, a plug and a medial wire termination device which includes an insulative housing with a socket receiving recess at one end and a plug engaging projection at the other end. Between the socket and the plug there are transversely spaced, generally parallel metallic contacts. On each of these metallic contacts there are a pair of wire receiving terminals each of which terminals is adjacent to a wire receiving aperture in the housing.

Abstract: Disclosed is an electrical header assembly comprised of an insulative housing having pins extending from its mounting and mating sides and a mounting bracket adjacent its mounting side. A coding bar is superimposed over its mating side and is retained in position by a horizontal support having a vertical footer positioned between the bracket and its mounting side.

Abstract: Disclosed is a multi-row right angle connector and a press block for installing the connector on a mounting substrate without soldering the contact pins. The connector legs comprise "eye of the needle" compliant interfaces that make electrical contact with the interior surfaces of the substrate's plated through holes. The press block is designed for use with a four-row right angle receptacle and locates rows 2, 3, and 4 on respective true grid positions and serves as a means for transmitting force from an external press to the contact pin tails. The contact tails in rows 2, 3, and 4 have a T-shaped shoulder that is pressed into a pocket in the press block. The insertion force is applied to the pins in row 1 by a corner having a radius matching the radius of the row 1 tails.

Abstract: Disposable tools for locating a power receptacle or a power pin within the corresponding port therefor in a header housing are disclosed. The tool for positioning a receptacle within a port includes a base having a positioning contour and a plug having an axis therethrough extending from the base. The plug is sized such that when the positioning contour on the base is engaged against at least two opposed lead-in surfaces about the port the plug extends into the barrel of the first receptacle to align the axis of the same with the axis of the port.The tool for positioning a pin within a port includes a sleeve having a central bore extending therethrough and an outer positioning surface thereon. The power pin is receivable in and retainable by the sleeve. The sleeve is sized such that when the positioning surface thereon engages against at least two opposed surfaces of the port the axis of the pin is retained in a predetermined relationship with the housing.

Abstract: A power port terminal formed by stamping from a blank of conductive material comprises a contact receiving socket portion and an integral mounting portion. The socket includes a web with a plurality of beams thereon. Each of the beams has a curved surface with a bend therein. The inner surface of the beams on the bends thereof define a substantially continuous cylindrical contact surface at a predetermined point along the reference axis of the terminal. The contact surface has a predetermined constricted dimension measured in a plane perpendicular to the reference axis, this dimension being the most constricted dimension along the reference axis of the terminal. The terminal is thereby able to accommodate a pin of any desired axial length. The trailing mounting portion has a set of mounting legs thereon that, the preferred instance, extend generally perpendicular to the reference axis of the terminal. Latch tabs may be provided one or more of the beams.

Abstract: A spacer is disposed in abutting relationship between the outer surfaces of a pin header and a shroud as the same are mounted to opposed major surfaces of a board. As a result, the pins of the header extend for substantially the same distances from the bases of the header and the shroud into the pockets thereof.

Abstract: In a system including a motherboard and a daughterboard a receptacle is disposed in an insulated housing mounted on the motherboard while a pin is disposed on the daughterboard. The receptacle comprises a socket and an integral threaded shank, the socket portion having an enlarged collar with an abutment surface thereon. The receptacle has a central and axial passage. The collar is larger than the dimension of an opening extending through the motherboard while the shank is sized to pass therethrough and to present the threads to the second surface thereof. A threaded nut engages with the threads on the shank accessible from the second surface of the motherboard. When the nut is threaded onto the shank the receptacle is held mechanically to the motherboard and into electrical connection with a conductive path thereon.

Abstract: A retaining arrangement for securing a housing of a connector to a substrate having a first and a second surface thereon and an opening therethrough includes a spring member connected at one end to the housing having a latching feature at the other end thereof. The spring member is deflectable upon insertion through the opening from a first surface of the substrate to generate a restoring force that acts generally perpendicularly to the substrate to draw the latching feature toward the housing into engagement with the second surface of the substrate.

Abstract: A connector interface for electrically mating a multi-row connector with a printed circuit board is defined by a flex circuit in the form of laminated polyimide layers having conductive traces for each interconnect pair with connection fields at the opposite ends of the traces for electrical connection to the terminal pins on the connector and the conductive pads or pins on the circuit board. The conductive traces are all of equal length to provide equal resistance and impedance paths for each of the circuit interconnects.
