Electrical connector

An electrical connector comprising:

• an insulating housing;
• contacts accommodated in the insulating housing;
• a retainer that is inserted from a front surface of the insulating housing, the retainer being locked to the insulating housing in a temporary locking position that allows the insertion of the contacts into the housing and in a main locking position that ensures that the contacts are prevented from slipping out of the insulating housing, the retainer having temporary locking arms extending to a free end thereof and comprising temporary locking projections that prevent the retainer from being pulled out when the retainer is in the temporary locking position, the temporary locking projections being exposed from side surfaces of the insulating housing when the retainer is in the main locking position;
• and
• the insulating housing having supporting parts that support a back surface of the temporary locking arms at the free end and in a vicinity of the temporary locking projections when the retainer is in the main locking position.

An electrical connector comprising:

• an insulating housing;
• contacts accommodated in the insulating housing;
• housing lances disposed within the insulating housing with spaces adjacent to the housing lances that allow the housing lances to flex to accommodate insertion of the contacts into the insulating housing, the housing lances securing the contacts in the insulating housing;
• and
• a retainer that is inserted from a front surface of the insulating housing and that is locked to the housing in a temporary locking position that allows the insertion of the contacts into the insulating housing and in a main locking position that ensures that the contacts are prevented from slipping out of the insulating housing, the retainer having main locking arms and temporary locking arms, the main locking arms comprising main locking projections that prevent the retainer from being pushed inward when the retainer is in the temporary locking position and that prevent the retainer from being pulled out when the retainer is in the main locking position, the main locking projections being exposed through openings in the insulating housing when the retainer is in the main locking position, the temporary locking arms comprising temporary locking projections that prevent the retainer from being pulled out when the retainer is in the temporary locking position;
• and
• the housing having supporting parts that support a back surface of the main locking arms in a vicinity of the main locking projections when the retainer is in the main locking position.
