An electrical distribution center assembly having a connector including a plurality of terminals and a terminal stabilizer plate engaging the tips of the terminals to hold the terminals in position and resist bending prior to inserting a mating connector into the electrical distribution center assembly. The terminal stabilizer plate is held in a ready position by a releasable latch means until an axial force applied to the releasable latch means by the mating connector body exceeds a force threshold, whereby the terminal stabilizer plate is released from the ready position and is moved to a seated position. The releasable latch means may include a flexible beam or other resilient member to hold the terminal stabilizer plate in the ready position until it is released.
