Abstract: To provide a connector is provided in which insulated portions of wires can be securely connected with the terminal fittings mounted in a connector housing. A main body 2 of a housing 1 is integrally provided with a cover 43 via a hinge 17 at its rear end. When terminal fittings 7 are mounted in the housing 1 with the cover 43 in its open position, insulation barrels 40 of the terminal fittings 7 are exposed. Wires 19 are connected with the insulation barrels 40 by moving a crimper 42 and an anvil 41 from above and below, respectively, thereby securing the wires 19.

Abstract: To prevent an electric wire cover from being attached upside down, ribs 16 and 24 are formed respectively on the outer peripheral upper face of a housing 10 and the inner peripheral lower face of an electric wire cover 20. Two wire distribution spaces 36U and 36L are provided between the housing 10 and the electric wire cover 20, extending along the upper and lower faces of the housing 10. When the electric wire cover 20 is correctly attached, the ribs 16 and 24 of the housing 10 and the electric wire cover 20 do not interfere with one another. However, when the electric wire cover 20 is upside down, the ribs 16 and 24 interfere with one another, thereby preventing the attachment of the electric wire cover 20.
