A communications connector has a shielded jack body and a wire cap. The shielded jack body has a single pair of plug interface contacts having a first thickness and a single pair of insulation displacement having a second smaller thickness. The plug interface contacts are configured to electrically connect to the insulation displacement contacts. The wire cap is configured to terminate a pair of conductors to the pair of insulation displacement contacts by being secured to the sheilded jack body in a direction perpendicular to a direction of an insertion of an associated connector.

A connector includes small-diameter shielded terminals 51 that are connected to small-diameter shielded electric wires 61, and a housing 10 that includes wide terminal housing parts 73 and a narrow terminal housing part 74. The wide terminal housing parts 73 include wide holding parts 35 and a lid part 41. The narrow terminal housing part 74 includes a narrow holding part 36 and the lid part 41. The lid part 41 includes a plate-like covering part 42 that covers openings in the wide holding parts 35 and the narrow holding part 36, and elastic pressure-receiving parts 43 that protrude from the plate-like covering part 42 into the wide terminal housing parts 73 and the narrow terminal housing part 74 and are elastically deformable under pressing forces of the small-diameter shielded electric wires 61 or the coated electric wire 67.
