Electrical connector with terminal position assurance device

摘要

A terminal position assurance (TPA) system is disclosed in an electrical connector assembly (20). The system includes a dielectric connector housing (32) having a plurality of terminal-receiving passages (46). A plurality of terminals (100) are insertable in an insertion direction (L) into the passages. A TPA device (26) is insertable into the housing and includes a plurality of fingers (90) movable in a direction transverse to the insertion direction (L) into the passages when the TPA device is moved from a pre-load position allowing insertion of the terminals (100) to a final position with the fingers (90) projecting into the passages (46) in engagement with the terminals. The TPA device (26) includes a pair of flexible latch arms (98) at opposite ends of the plurality of terminals for holding the TPA device in at least one of its pre-load and final positions. The flexible latch arms (98) are flexible in the same direction of movement of the fingers (90) into the terminal-receiving passages (46).
