The electric wire includes a terminal which is provided at an end of the electric wire. The inner housing includes a terminal accommodation chamber configured to accommodate the electric wire with the terminal. The outer housing is configured to accommodate the inner housing. The inner housing has an opening which opens in a terminal fitting direction intersecting with an extending direction of the electric wire so that the electric wire and the terminal are inserted into the terminal accommodation chamber through the opening. The cover part is configured to cover a part of the opening. ## Claims ### Claim 1 A connector comprising: an electric wire; a terminal which is provided at an end of the electric wire; an inner housing including a terminal accommodation chamber configured to accommodate the terminal and an electric wire accommodation chamber configured to accommodate the electric wire; an outer housing configured to accommodate the inner housing; and a cover part connected to the inner housing through a hinge part having a rotation axis extending along an extending direction of the electric wire, wherein the cover part is configured to cover only the electric wire accommodation chamber in the inner housing such that the terminal accommodation chamber remains to be open when the cover part is closed. ### Claim 2 (depends on 1) The connector according to claim 1, wherein a shape of the terminal accommodation chamber viewed from the terminal fitting direction corresponds to an outer shape of the terminal, and the shape of the terminal accommodation chamber is asymmetrical with respect to the extending direction of the electric wire. ### Claim 3 (depends on 2) The connector according to claim 2, wherein an engaging wall protrudes from an inner side wall defining the terminal accommodation chamber, so as to define a slit, and the engaging wall is configured to come in contact with a corner part of the terminal at the extending direction so as to prevent the electric wire from falling out. ### Claim 4 (depends on 1) The connector according to claim 1, wherein the outer housing has an electric wire pullout opening so that the inner housing is inserted through the electric wire pullout opening in the extending direction of the electric wire. ### Claim 5 (depends on 4) The connector according to claim 4, further comprising: a stepped part protruding from an inner wall of the outer housing, wherein a protruding tip of the stepped part is configured to support the inner housing, an end face of the stepped part at a side of the electric wire pullout opening in the extending direction is configured to come in contact with an end face of the cover part in the extending direction when the inner housing is inserted into the outer housing, and a tip imaginary line of the end face of the stepped part is curved so that a position corresponding to an edge of the cover part opposite to the hinge part is located on a far side in an inner housing insertion direction in which the inner housing is inserted into the outer housing in the extending direction. ### Claim 6 (depends on 5) The connector according to claim 5, wherein the stepped part includes a plurality of ribs extending in the inner housing insertion direction and provided in parallel to each other with intervals therebetween in an inner peripheral direction of the outer housing. ### Claim 7 (depends on 1) The connector according to claim 1, wherein a protrusion configured to press the electric wire is provided in the cover part. ### Claim 8 (depends on 1) The connector according to claim 1, wherein the outer housing has an electric wire pullout opening so that the inner housing is inserted through the electric wire pullout opening in the extending direction of the electric wire, and a sealing member is provided between the electric wire pullout opening and the electric wire. ### Claim 9 A connector comprising: an electric wire including a terminal which is provided at an end of the electric wire; an inner housing including a terminal accommodation chamber configured to accommodate the electric wire with the terminal; an outer housing configured to accommodate the inner housing; a cover part; and a stepped part protruding from an inner wall of the outer housing, wherein the inner housing has an opening which opens in a terminal fitting direction intersecting with an extending direction of the electric wire so that the electric wire and the terminal are inserted into the terminal accommodation chamber through the opening, and the cover part is configured to cover a part of the opening, wherein the outer housing has an electric wire pullout opening so that the inner housing is inserted through the electric wire pullout opening in the extending direction of the electric wire, the cover part is connected to the inner housing by a hinge part, and the hinge part extends in the extending direction, a protruding tip of the stepped part is configured to support the inner housing, an end face of the stepped part at a side of the electric wire pullout opening in the extending direction is configured to come in contact with an end face of the cover part in the extending direction when the inner housing is inserted into the outer housing, and a tip imaginary line of the end face of the stepped part is curved so that a position corresponding to an edge of the cover part opposite to the hinge part is located on a far side in an inner housing insertion direction in which the inner housing is inserted into the outer housing in the extending direction. ### Claim 10 (depends on 9) The connector according to claim 9, wherein the stepped part includes a plurality of ribs extending in the inner housing insertion direction and provided in parallel to each other with intervals therebetween in an inner peripheral direction of the outer housing.
