Electrical connector with terminal position assurance system

摘要

An electrical connector assembly includes an elongated housing having a plurality of terminal-receiving cavities extending transversely of the housing. The cavities are arranged in at least two rows lengthwise of the housing, and two rows of terminal-protective silos project forwardly of a front mating face of the housing in alignment with the cavities. Two generally parallel channels run longitudinally of the housing and intersect the two rows of cavities. A longitudinal solid wall portion of the front mating face of the housing extends lengthwise between the two rows of forwardly projecting silos. A plurality of slits are formed in the front mating face between adjacent silos in alignment with transverse walls between the cavities, the slits extending rearwardly to the channels. A plurality of terminals are adapted to be inserted into the cavities to fully inserted positions in the forwardly projecting silos. The terminals have portions adapted to block the channels if the terminals are not in their respective fully inserted positions. An elongated bifurcated terminal position assurance device includes a pair of longitudinal legs insertable into the two channels unless one of the channels is blocked by a portion of one of the terminals in either row thereof.
