Abstract: In a specific embodiment, a connector 100 is disclosed. The connector 100 comprises an insulative housing 102 defining a rear opening 108 for receiving a plurality of electrical wires 110 and a front opening 106 and a circuit board 104 disposed in the housing 102 and comprising a mating section 112 for mating with a corresponding mating section of a mating connector. The mating section 112 protrudes outwardly from the front opening 106 and terminates at a front edge 118 disposed between opposing side edges 114,116 of the mating section 112. The connector 100 further comprises opposing side arms 128,130 extending forwardly from opposing lateral sides 124,126 of the front opening 106 along, adjacent and beyond corresponding side edges 114,116 of the mating section 112 with a maximum separation between each side edge 114,116 and the corresponding side arm 128,130 being sufficiently small so that when the connector 100 mates with a mating connector, no portion of the mating connector can be inserted between the side edge 114,116 and the corresponding side arm 128,130. Other exemplary embodiments are also disclosed.

Abstract: An electrically conductive contact of an electrical connector includes an L-shaped main body comprising first and second legs connected at a junction. The first leg is configured to make physical and electrical contact with a first electric conductor. The contact includes an elongated resiliently flexible arm extending from an end of the second leg toward the junction and making an acute angle with the second leg at the end of the second leg. The flexible arm is configured to make solderless contact with a second electric conductor by pressing against the second electric conductor and resiliently flexing toward the second leg.

Abstract: A connector assembly, configured to mate with a mating connector along a mating direction, includes a circuit board, at least one cable, an insulative housing, an electrically conductive unitary shield, a pull tab, and a retention feature. The cable includes a plurality of conductors having front ends terminated at conductive pads of the circuit board. The housing is tightly overmolded around at least a portion of the circuit board. A mating end of the circuit board extends forwardly from a mating face of the housing. The shield includes a top wall extending between a back end and a front end thereof. The pull tab is rotatably attached to the shield near a front end of a top wall of the shield. The retention feature of the shield engages a corresponding retention feature of the mating connector to prevent the connector assembly from unmating from the mating connector.
