Center load terminal position assurance for an electrical connector

摘要

An electrical connector includes a housing having a plurality of terminal towers with terminal channels therein. The terminal towers surround a central cavity. A TPA device is front loaded into the central cavity through a mating end in a loading direction. The TPA device includes a locking device having locking tabs. The locking device is loaded into the central cavity in the loading direction to a loaded position and moved in a locking direction generally perpendicular to the loading direction to a locked position. The locking tabs are at least partially received in the terminal channels in corresponding terminal towers in blocking positions for blocking removal of the terminals from the terminal channels when in the locked position.
