Electrical connector with flat-type conductor and electrical connector assembly

An electrical connector assembly comprising:

• an electrical connector with a flat-type conductor configured to matingly connect a front end section of a flat-type conductor with a strip-like configuration extending in a forward-backward direction to a counterpart electrical connector;
• and
• the counterpart electrical connector to which said electrical connector with the flat-type conductor is matingly connected,
• wherein said electrical connector with the flat-type conductor comprises:
• the flat-type conductors;
• and
• a housing holding the front end section of the flat-type conductor,
• wherein the housing comprises a locking portion lockable to the counterpart electrical connector and receiving spaces configured to receive counterpart terminals provided in the counterpart electrical connector, and
• wherein the locking portion, along with being positioned differently from a position of the receiving spaces when viewed in a thickness direction of the flat-type conductor, is positioned so as to at least partially overlap with the receiving spaces in the thickness direction of the flat-type conductor, the locking portion comprises:
• a locking arm portion extending in the forward-backward direction and resiliently deformable in the thickness direction of the flat-type conductor;
• and a locking engagement portion engageable with the counterpart electrical connector.
