An electrical connector includes a housing having a plurality of terminal passages. Each terminal passage has a deflectable latch for securing the terminal within the passage and is configured to permit an electrical terminal to be inserted into the passage. Openings are provided proximate the deflectable latches, with each opening extending from a first terminal passage of the plurality of terminal passages to an adjacent second terminal passage. Projections extend from side surfaces of the terminal passages, with at least one projection extending into each terminal passage. At least one projection is positioned to cooperate with a side surface of a respective deflectable latch to prevent the deflectable latch from being overstressed. The openings and the projections allow the terminal passages to be closely spaced thereby reducing the size of the connector while providing overstress protection for the deflectable latches.
