Referring to FIG. 10 , a terminal 180 is inserted into the housing 100 .

The terminal 180 may pass through the rear wall hole 100H and proceed toward the terminal seating space 103S. While the terminal 180 is seated in the terminal seating space 103S, the lance unit 104 may be elastically moved such that the first locking protrusion 104b is inserted into the locking groove 123T. As an example, the terminal 180 may include an extension 184 disposed on the rear end of the contact 182 . The expansion part 184 may have an extended shape compared to the contact part 182 . While the terminal 180 is seated in the terminal seating space 103S, the lance unit 104 may be elastically moved by the extension unit 184. At this time, the first locking protrusion 104b may be inserted into the locking groove 123T.

Referring to FIG. 11 , the terminal 180 is completely inserted into the housing 100 .

For example, the terminal 180 may be completely seated within the terminal seating space 103S. When the terminal 180 is completely seated, the first locking protrusion 104b can be extracted from the locking groove 123T. For example, as the terminal 180 is completely seated in the terminal seating space 103S, the elastically operated lance unit 104 may be restored.
