Connector

A connector, comprising:

• a housing comprising at least one terminal accommodating chamber, and at least one lance projecting into the terminal accommodating chamber and capable of withdrawing from the terminal accommodating chamber due to elastic deformation of the lance;
• at least one terminal which can be inserted into the terminal accommodating chamber, the terminal having a terminal contact part formed on a leading side thereof for contact with a mating terminal and an engagement part formed for engagement with the lance;
• and
• a front holder fitted to a front part of the housing to move between a formal engagement position and a temporary engagement position to hold the terminal contact part, wherein
• in the process of inserting the terminal into the terminal accommodating chamber, the lance is elastically deformed in a direction to withdraw from the terminal accommodating chamber to allow the terminal to be inserted into the terminal accommodating chamber,
• in a terminal's position where an insertion of the terminal into the terminal accommodating chamber is completed, the lance is elastically recovered to engage with the engagement part, and
• the housing is provided with an opening which exposes an engagement point between the lance and the engagement part in a direction generally perpendicular to an elastically-deformable direction of the lance.
