That is, as illustrated in FIGS. 5A and 5B, the housing body 150 is provided with a flexible lance 161 for each terminal accommodating chamber 152, and the terminal 164 is connected from the rear. When inserted, the lance 161 is bent once according to the insertion and is elastically restored, and the engaging end of the lance 161 is engaged with the stepped portion of the terminal 164, thereby preventing the terminal 164 from coming out backward.

  When the terminal 164 is locked with the lance 161 in this way, when the terminal 164 is inserted to a fixed position, a sense of moderation is obtained by elastic recovery of the lance 161. Therefore, whether or not the terminal 164 has been assembled properly. There is a merit that the operator can confirm by touch of hands and fingers.

  Further, as illustrated in FIGS. 5A and 5B, a retainer 162 for locking the terminal 164 may be provided in addition to the lance 161. The retainer 162 is attached to an opening 166 formed in the housing main body 150 after assembling all the terminals 164, and is rotatably connected to the housing main body 150 via a hinge 165. . When the retainer 162 is attached to the opening 166 after all the terminals 164 are inserted, the locking portions 167 of the retainer 162 are engaged with all the terminals 164, thereby double-locking the terminals 164. Accordingly, the holding of the terminal 164 can be further ensured.
