each of the pair of housing-side lock parts includes:

a locked part extending in an electric wire extraction direction of the electric wire extraction part; and

a stopper preventing displacement of the protector-side lock part engaged with the locked part in the electric wire extraction direction,

each of the pair of protector-side lock parts includes:

an arm flexibly deformable in a direction orthogonal to the electric wire extraction direction; and

a locking claw part provided at a tip end of the arm, and

the arms are flexibly deformed in opposite directions to allow the locking claw parts to be engaged with the locked parts upon the protector being assembled to the housing from the direction orthogonal to the electric wire extraction direction.

2. The shield connector according to claim 1 , wherein the protector comprises:

a base member; and

a cover connected to the base member through a hinge and capable of opening and closing at least a region of the base member toward an assembly direction of the base member.

3. The shield connector according to claim 2 , wherein

the base member comprises a bottom plate part and a pair of rising side parts rising from both of left and right ends of the bottom plate part,

the cover has a shape of covering a top surface, left and right side surfaces, and a back surface of the base member,

the hinge connects one of the rising side parts and one end of the cover to each other.

4. The shield connector according to claim 3 , wherein the cover is capable of being displaced between:

a covering position covering spaces on the top surface, left and right side surfaces, and the back surface of the base member and

an open position for opening the spaces on the top surface, left and right side surfaces, and the back surface of the base member based on the flexural deformation of the hinge.

5. The shield connector according to claim 2 , wherein

the base member comprises a pair of left and right protector-side auxiliary lock parts formed on the rising side parts of the protector together with the pair of left and right protector-side lock parts,

the pair of left and right protector-side auxiliary lock parts are arranged inside of the protector-side lock parts, and

each of the pair of left and right protector-side auxiliary lock parts comprises an upper stopper step surface formed on a top thereof.

6. The shield connector according to claim 1 , wherein

the housing includes a pair of housing-side auxiliary lock parts,

the protector includes a pair of protector-side auxiliary lock parts,

each of the pair of housing-side auxiliary lock parts includes

a position restriction part extending in the electric wire extraction direction of the electric wire extraction part, and

a stopper preventing displacement of the protector-side auxiliary lock part in the electric wire extraction direction, and

the pair of protector-side auxiliary lock parts are engaged with the position restriction parts and the stoppers of the pair of housing-side auxiliary lock parts, upon the protector being assembled to the housing from the direction orthogonal to the electric wire extraction direction.

7. The shield connector according to claim 1 , wherein a portion between the outer circumference of the housing and an inner circumference of the shield shell is sealed by a shell packing, and a unit packing is formed on the outer circumference of the housing.

8. The shield connector according to claim 1 , wherein

the terminal comprises a pair of terminals,

an electric wire is connected to the pair of terminals, and

the electric wire extends in the electric wire extraction direction from the housing, and is covered by the protector.

9. The shield connector according to claim 1 , wherein

the housing comprises a flange part provided at a back side of the housing, the flange part projecting in a direction orthogonal to the electric wire extraction direction are.

10. The shield connector according to claim 9 , wherein the pair of left and right housing-side lock parts project from a surface of the flange part.

11. The shield connector according to claim 1 , wherein the housing further comprises a pair of left and right housing-side auxiliary lock parts arranged inward from the pair of left and right housing-side lock parts.

12. The shield connector according to claim 11 , wherein

the housing comprises a flange part provided at a back side of the housing, the flange part projecting in a direction orthogonal to the electric wire extraction direction are,

the pair of left and right housing-side auxiliary lock parts project from the surface of the flange part, and

the pair of left and right housing-side auxiliary lock parts comprise position restriction parts extending in the electric wire extraction direction of the electric wire extraction part and stoppers.
