The housing includes a cavity extending through the housing from the mating side to the mounting side. The receptacle contact is disposed within the cavity and is configured to receive a mating contact of the mating connector. The receptacle contact includes elongated shafts disposed on opposite sides of a longitudinal axis and mating tips coupled to the shafts. The mating tips have tapered shapes between the shafts and outer ends of the mating tips. The tapered shapes are wider than the shafts in a lateral direction that is transverse to the longitudinal axis. The receptacle contact is configured to receive a mating contact of a mating connector between the mating tips to electrically couple the mating connector with the receptacle connector. ## Claims ### Claim 1 A receptacle connector configured to mate with a mating connector, the receptacle connector comprising: a housing having a mating side configured to engage the mating connector and a mounting side configured to be mounted to a substrate, the housing including a cavity extending through the housing from the mating side to the mounting side; and a receptacle contact disposed within the cavity and configured to receive a mating contact of the mating connector, the receptacle contact comprising outwardly protruding barbs and openings disposed to permit the barbs to inwardly collapse when the receptacle contact is loaded into the cavity and the barbs engage the housing, the receptacle contact further comprising elongated shafts disposed on opposite sides of a longitudinal axis and tapered mating tips coupled to the shafts, the mating tips having tapered shapes between the shafts and outer ends of the mating tips, the mating tips and the shafts extending between opposite sides in directions oriented parallel to a lateral axis, the opposite sides of the mating tips laterally extending farther from the longitudinal axis than the opposite sides of the shafts, wherein the receptacle contact is configured to receive the mating contact of the mating connector between the mating tips. ### Claim 2 (depends on 1) The receptacle connector of claim 1, wherein the housing comprises a separation element disposed within the cavity, the mating tips of the receptacle contact engaging the separation element to maintain a separation distance between the mating tips in a direction that is transverse to the longitudinal axis and to the lateral directions. ### Claim 3 (depends on 1) The receptacle connector of claim 1, wherein the receptacle contact is a unitary conductive body. ### Claim 4 (depends on 1) The receptacle connector of claim 1, wherein the tapered shape of each of the mating tips is approximately symmetrical on opposite sides of the longitudinal axis. ### Claim 5 (depends on 1) The receptacle connector of claim 1, wherein the housing includes a separation element protruding into the cavity from an inner wall of the cavity and extending from one side to an opposite side in a direction extending between the mating tips of the receptacle contact, each of the sides engaging a different one of the mating tips prior to receiving the mating contact between the mating tips. ### Claim 6 (depends on 1) The receptacle connector of claim 1, wherein the cavity holds a single receptacle contact. ### Claim 7 (depends on 1) The receptacle connector of claim 1, wherein the receptacle contact includes a mounting portion configured to mount the receptacle contact to the substrate and a retention portion interconnecting the contact beams with the mounting portion, wherein the retention portion secures the receptacle connector in the cavity. ### Claim 8 (depends on 7) The receptacle connector of claim 7, wherein the retention portion includes retention members protruding from the retention portion and configured to engage the housing. ### Claim 9 (depends on 7) The receptacle connector of claim 7, wherein the retention portion includes the barbs. ### Claim 10 A receptacle connector comprising: a housing having a cavity extending along a longitudinal axis and shaped to receive a contact pin of a mating connector, the housing comprising a separation element protruding into the cavity; and a receptacle contact disposed within the cavity and including a protruding barb and an opening, the barb engaging the housing and securing the receptacle contact in the housing, the opening positioned to permit the barb to inwardly collapse, the receptacle contact further comprising contact beams disposed on opposite sides of and extending along the longitudinal axis, the contact beams receiving the contact pin of the mating connector, wherein the contact beams engage the separation element and the separation element maintains a separation distance between the contact beams in the cavity. ### Claim 11 (depends on 10) The receptacle connector of claim 10, wherein the contact beams include mating tips joined to elongated shafts, the mating tips being tapered from a coupling end to an outer end, the mating tips and the shafts extending between opposite sides, further wherein the opposite sides of the mating tips laterally extend in directions oriented perpendicular to the longitudinal axis farther than the opposite sides of the shafts. ### Claim 12 (depends on 11) The receptacle connector of claim 11, wherein the coupling ends of the mating tips engage the separation element in the housing to maintain the separation distance between the contact beams. ### Claim 13 (depends on 10) The receptacle connector of claim 10, wherein the contact beams comprise retention members extending in a direction transverse to the longitudinal axis to engage the housing and retain the receptacle contact in the cavity. ### Claim 14 (depends on 10) The receptacle connector of claim 10, wherein the housing comprises recesses on opposing sides of the cavity, the recesses shaped to permit the contact beams to be deflected in opposing directions transverse to the longitudinal axis. ### Claim 15 (depends on 10) The receptacle connector of claim 10, wherein the contact beams of the receptacle contact include mating tips having symmetrical tapered shapes, each of the mating tips being approximately symmetrical on opposite sides of the longitudinal axis. ### Claim 16 (depends on 10) The receptacle connector of claim 10, wherein the separation element extends from one side to an opposite side in a direction extending between the contact beams of the receptacle contact, each of the sides engaging a different one of the contact beams prior to receiving the contact pin between the contact beams. ### Claim 17 (depends on 10) The receptacle connector of claim 10, wherein the cavity holds a single receptacle contact. ### Claim 18 (depends on 10) The receptacle connector of claim 10, wherein the contact beams of the receptacle contact have symmetrically tapered mating tips joined with the contact beams, the mating tips having larger widths in directions parallel to a lateral axis than largest widths of the contact beams in directions parallel to the lateral axis. ### Claim 19 (depends on 10) The receptacle connector of claim 10, wherein the receptacle contact comprises a mounting portion interconnected with the contact beams and configured to mechanically and electrically couple the receptacle contact with a substrate. ### Claim 20 (depends on 19) The receptacle connector of claim 19, further comprising a retention portion interconnecting the contact beams with the mounting portion, wherein the retention portion engages the housing to limit movement of the receptacle contact in the cavity along the longitudinal axis.
