Abstract
Abstract An electrical connector includes a housing having terminal chambers, terminals which are inserted into the chambers, and a terminal engagement holder provided with a locking anchor for an engagement portion of the housing in order to be assembled with the housing by two-steps of manipulation, which are a step of tentatively engaging the holder with the housing, and the other step of thereafter engaging the holder with the housing on a full scale. The locking anchor functions to urge the holder toward the housing while the holder is in the full-scale engagement with the rear portion of the housing, so that the holder can be surely engaged with the housing on the full scale even if the rear end of each of the terminals is located slightly behind a prescribed position.
