A connector housing (1, 101), comprising: a board (11a, 111a) which supports a conductor exposed portion (Wa) bent in a U shape at a fore-end of a harness when a side from which a mating connector is fitted is set as the front, wherein the board (11a, 111a) has a front end edge where a U-shaped bent portion of the conductor exposed portion (Wa) is arranged, a lower surface serving as a first plate surface on which a part of the conductor exposed portion (Wa) closer to a base-end side than the U-shaped bent portion is arranged along a front-rear direction, and an upper surface serving as a second plate surface on which a part of the conductor exposed portion (Wa) closer to a fore-end side than the U-shaped bent portion is arranged along the front-rear direction; a harness guide portion (23, 123) which is arranged on one plate surface of the first plate surface and the second plate surface and support the part on the fore-end side or the part on the base-end side of the conductor exposed portion (Wa) when arranged on the one plate surface, the part serving as an electric contact when in conductive contact with an electric contact of the mating connector; the connector housing being characterized in that: a cover (50, 150) which clamps the harness between the board (11a, 111a) and the cover (50, 150) by being in surface matching with other plate surface of the first plate surface and the second plate surface; a coupling part (16, 56, 116, 156) which couples the board (11a, 111a) and the cover (50, 150) in a state when the harness is clamped therebetween and releases the coupling between the board (11a, 111a) and the cover while being disengaged; and a front projecting piece (52,152) and a rear projecting piece (53, 153) which are arranged at a front end and a rear end of the cover (50, 150), and restrict, by being respectively engaged with a front end and a rear end of the board (11a, 111a), a position of the board (11a, 111a) in the front-rear direction when the cover (50, 150) is coupled to the board (11a, 111a). a board (11a, 111a) which supports a conductor exposed portion (Wa) bent in a U shape at a fore-end of a harness when a side from which a mating connector is fitted is set as the front, wherein the board (11a, 111a) has a front end edge where a U-shaped bent portion of the conductor exposed portion (Wa) is arranged, a lower surface serving as a first plate surface on which a part of the conductor exposed portion (Wa) closer to a base-end side than the U-shaped bent portion is arranged along a front-rear direction, and an upper surface serving as a second plate surface on which a part of the conductor exposed portion (Wa) closer to a fore-end side than the U-shaped bent portion is arranged along the front-rear direction; a harness guide portion (23, 123) which is arranged on one plate surface of the first plate surface and the second plate surface and support the part on the fore-end side or the part on the base-end side of the conductor exposed portion (Wa) when arranged on the one plate surface, the part serving as an electric contact when in conductive contact with an electric contact of the mating connector; the connector housing being characterized in that: a cover (50, 150) which clamps the harness between the board (11a, 111a) and the cover (50, 150) by being in surface matching with other plate surface of the first plate surface and the second plate surface; a coupling part (16, 56, 116, 156) which couples the board (11a, 111a) and the cover (50, 150) in a state when the harness is clamped therebetween and releases the coupling between the board (11a, 111a) and the cover while being disengaged; and a front projecting piece (52,152) and a rear projecting piece (53, 153) which are arranged at a front end and a rear end of the cover (50, 150), and restrict, by being respectively engaged with a front end and a rear end of the board (11a, 111a), a position of the board (11a, 111a) in the front-rear direction when the cover (50, 150) is coupled to the board (11a, 111a). a cover (50, 150) which clamps the harness between the board (11a, 111a) and the cover (50, 150) by being in surface matching with other plate surface of the first plate surface and the second plate surface; a coupling part (16, 56, 116, 156) which couples the board (11a, 111a) and the cover (50, 150) in a state when the harness is clamped therebetween and releases the coupling between the board (11a, 111a) and the cover while being disengaged; and a front projecting piece (52,152) and a rear projecting piece (53, 153) which are arranged at a front end and a rear end of the cover (50, 150), and restrict, by being respectively engaged with a front end and a rear end of the board (11a, 111a), a position of the board (11a, 111a) in the front-rear direction when the cover (50, 150) is coupled to the board (11a, 111a).
