Patent attributes
A connector 1 includes a connector housing 2, and a retainer 3. The retainer 3 includes lances 6 which are inserted into respective terminal receiving spaces 21 through respective opening portions 28 to be retainingly engaged respectively with metal terminals 4, and a lance abutment portion 8 which abuts against the lances 6 to hold the lances 6 in retainingly-engaged relation to the respective metal terminals 4. The amount of insertion of the lance 6 in the terminal receiving space 21 before the lance is retainingly engaged with the metal terminal 4 is equal to the amount of insertion of the lance 6 in the terminal receiving space 21 when the lance is retainingly engaged with the metal terminal 4. When the metal terminal 4 is kept half inserted, the lance 6 is located outwardly of the terminal receiving space 21, so that the lance abutment portion 8 is held in a lifted condition, from which it is detected that and the metal terminal 4 is half inserted in the terminal receiving space 21.
