Abstract

A connector component includes a housing portion and an insert portion. The insert portion includes a plurality of terminal-receiving passages. Conductive terminals may be inserted into the passages, and a ramped fixed shoulder is formed on each passage surface for retaining the terminals in the passage. Additionally, a flexible finger is provided for each passage for holding the terminals in position in the passage. A terminal may be loaded into each passage and disposed in front of the shoulder. The housing portion of the invention includes a generally box-shaped casing having a hollow cavity for receiving the insert portion of the invention. Each of the upper and lower walls includes a transverse step formed along the expanse between the side walls. The upper and lower walls further include a transverse ramped locking area which also extends between the side walls. The transverse step serves as part of a terminal position assurance ('TPA') system for preventing assembly of the insert portion into the housing if a terminal is not properly seated in its passage. When a terminal is not properly seated, the finger for that passage will extend outward more than the remaining fingers, and this finger will contact the transverse step on the upper or lower wall. The step will prevent further insertion of the insert and alert a technician assembling the component as to the incorrectly positioned terminal. However, when all terminals are properly seated, there is sufficient clearance for the insert to be completely inserted into the housing. As complete insertion occurs, the fingers on the insert contact the ramped locking area. The ramped area forces the fingers against the terminals, thereby securely locking the terminals in position.
