The application discloses an improved interposer assembly with a molded plastic plate and stamp-formed metal contacts inserted in through passages in the plate. The contacts have redundant separate metal circuit paths extending between opposed contact points to reduce inductance and contact resistance.

Interposer assembly and method

An interposer plate assembly having an insulating plate and metal contacts in the plate with contact points above and below the plate and a central portion in the plate. Two cantilever arms extend from the central portion to each contact point. The central portion may be formed to have a large area to form an impedance shield for reducing impedance between adjacent signal contacts. Plastic bodies may be overmolded on separate contacts or on contact pairs and may have sliding fits in passages of the interposer plate. Contacts may be arranged as differential pairs with ground contacts located between the differential pairs.

Impedance controlled LGA interposer assembly

An interposer assembly includes an insulating plate with passages extending through the thickness of the plate and projections extending into the passages. Metal contacts are loosely confined in the passages by the projections. The contacts include noses that project outwardly from the plate for engagement with contact pads on overlying and underlying circuit members.

A low profile, surface-mounted receptacle includes a housing having a cavity defined at least in part by the interior surfaces of the sidewalls thereof. The interior surface of at least one sidewall has a groove, one wall of the groove being defined by an inclined portion. An electrical spring contact is received within the groove, the contact being of the curved, dual cantilever type having a first leg, a curved transition portion and a second leg. The contact being disposed to define a clearance space between itself and the inclined. The legs and curved portion responding to the introduction of a male plug by cantilever toward the inclined sidewall and undergoing a reduction in the radius of curvature, thereby displacing to an extent sufficient to exert a predetermined normal force on the plug, despite dimensional variations in the housing due to manufacture.

A shielded ribbon cable electrical connector assembly includes a shielded cable connector with an overmolded body mounted on the end of the shielded cable and a shielded pin header adapted to be mounted on a circuit board and to mate with the connector. The connector includes a cable clamp on the end of the cable, a premolded connector block containing a row of disconnect terminals and a circuit board forming electrical connections between conductors in the cable and terminals in the connector block. A ground shield plate overlies the circuit board and includes a contact tongue which extends into the cable clamp and is held against the cable shield and a contact finger which overlies the connector block and forms a ground connection with a ground shield on the header. An overmolded plastic body surrounds the cable clamp, circuit board, connector ground shield and part of the connector block.

A retention system for retaining a connector housing to a substrate includes a pair of slotted arms extending from the housing and a wedge-shaped abutment member having a camming surface and a latching surface thereon. One leg of an L-shaped clip is insertable into a channel defined by the slotted arms. The top edge of this leg of the clip is notched to form a tab. The clip is deflectable by the camming surface as the leg advances into the channel until the latch bar on the clip snaps into latching engagement with the latching surface on the abutment member, thereby to secure the clip to the housing. The second leg of the clip is bent to underlie the connector housing when the clip is attached thereto.

An electrical connector assembly includes a pair of elongate connector blocks with a plurality of terminals in each block, latch members on the ends of one block and a latch assembly on the ends of other block. The latch assemblies include rotary latches and latch operators extending between the rotary latches and the adjacent body. Manual actuation of the operators rotate the latches between opened and closed positions.

The leg of an L-shaped clip is insertable into a channel defined by the slotted arms. The clip is deflectable by the camming surface as the leg advances into the channel until at latch bar on the clip snaps into latching engagement with the latching surface on the abutment member, thereby to secure the clip to the housing. The clip is attachable to the substrate to retain the housing to the same.

An electrical connector adapted to be mounted on a circuit board, said connector having at least two legs, each of said legs being adapted to fit snugly into a corresponding hole on said circuit board, each leg having a cross section perpendicular to its long axis which is a closed geometric shape having a major axis substantially perpendicular to a minor axis, the length of said major axis being greater than the diameter of the corresponding mounting hole in the circuit board and the length of the minor axis being somewhat less than the diameter of the corresponding mounting hole in the circuit board, and a process for securing a contact wire within a plastic connector comprising ultrasonically melting a portion of the plastic in contact with said wire along a portion of the length of said wire and then allowing the plastic to solidify.
