  • Patent number: 10873159
    Abstract: An electrical connector, and method of assembly, that has a conductive connector shell and a contact subassembly received therein. The contact subassembly has first and second signal wafers and a ground wafer sandwiched between the signal wafers. Each of the signal wafers includes one or more signal contacts and a dielectric wafer body formed around the signal contacts such that the tail and mating ends of the signal contacts are outside of the wafer body. The ground wafer includes one or more ground contacts and a dielectric wafer body formed around the ground contacts such that the tail ends of the ground contacts are outside of the wafer body of the ground wafer.

  • Patent number: 10243307
    Abstract: A wafer assembly for an electrical connector, and method for making, that has a first and second wafers configured to interlock with one another. Each of the wafers has at least one contact that has a body portion with a mating end for coupling to a mating contact and a tail end opposite the mating end for engaging a printed circuit board where the mating and tail ends extend from opposite sides of the wafer. A conductive spring member is sandwiched between the first and second wafers. The wafer assembly can include one or more electronic components in electrical contact with the spring member and one of the contacts.

  • Patent number: 9450322
    Abstract: The present invention relates to electrical contacts having tines with uneven edges to provide increased contact normal force and decreased peak stress. The socket electrical contact contains a socket body that includes a base defining a longitudinal axis and tines extending from the base at spaced-apart locations around the circumference of the base. The tines extend from the base in the direction of the axis to define a pin reception zone between the tines. Each tine contains two opposing edges that have different lengths and a blunt tip.

  • Patent number: 9362638
    Abstract: A contact wafer that has a plurality of contacts. Each of the contacts has a body portion with a mating end and an opposite tail end. The mating end is configured to couple to a mating contact and the tail end is configured to engage a printed circuit board. An overmold surrounds the body portions of the contacts such that the mating ends and the tails ends of the contacts are exposed and extend from opposite ends of said overmold. The overmold has a first side that includes a plurality of recessed surfaces. Each recessed surface is between adjacent body portions of the contacts and sized to receive a corresponding portion of an overmold of another contact wafer.
