An electrical connector having a terminal position assurance device

摘要

An electrical connector (10) having a housing body (12) with a contact receiving passage (14) therein. The contact receiving passage (14) has a contact retention arm (30) for securing a contact within the passage (14). A terminal position assurance member (50) has an outer wall (52') with an inner shoulder (54) and a locking surface (56). The outer wall (52') is received around the arm (30). The terminal position assurance member (50) has a first position in which it forms a space (58) behind the arm (30) and a second position wherein the locking surface (56) is received behind the arm (30) thereby preventing deflection of the arm (30). An improperly positioned contact deflecting the arm (30) into the space (58) causes the shoulder (54) to abut the arm (30) and prevent the terminal position assurance member (50) progressing to its second position.
