Shielded connector

1. A shielded connector comprising:

at least four distinct layers,

wherein the four distinct layers include:

a shield member having a front end, a rear end and a braided wire that encloses a bundle of a plurality of wires, the plurality of wires being drawn out of the rear end of the shield member;

a shield shell having a cylindrical shape and being fixed to the front end of the shield member;

a caulk ring disposed on an outer circumference of the shield shell to hold and fix the shield member between the shield shell by caulking; and

a rigid underlay ring that has a closed shape in cross section and receives caulking force to be applied to the shield shell from an outer circumferential side of the shield shell when the caulking is performed, the underlay ring being formed separately from the shield shell and disposed on an inner circumference of the shield shell at a position corresponding to the caulk ring.

2. The shielded connector according to claim 1 , wherein the caulk ring and the underlay ring are disposed at a position where the shield member and the shield shell are connected by the caulking.

3. The shielded connector according to claim 1 , further comprising a housing to which at least part of the shield shell is attached.

4. A shielded connector comprising:

at least four distinct layers,

wherein the four distinct layers include:

a shield member having a front end, a rear end and a braided wire that encloses a bundle of a plurality of wires, the plurality of wires being drawn out of the rear end of the shield member;

a shield shell having a cylindrical shape and being fixed to a front end of the shield member;

a caulk ring disposed on an outer circumference of the shield shell to hold and fix the shield member between the shield shell by caulking;

a rigid underlay ring that has a closed shape in cross section and receives caulking force to be applied to the shield shell from an outer circumferential side of the shield shell when the caulking is performed, the underlay ring being formed separately from the shield shell and disposed on an inner circumference of the shield shell at a position corresponding to the caulk ring; and

a housing to which at least part of the shield shell is attached,

wherein the housing includes:

a body portion that retains a plurality of terminal fittings each attached to an end of the corresponding wires;

a cylindrical fitting portion that encloses the body portion; and

a coupling portion that couples the body portion and the cylindrical fitting portion.

5. The shielded connector according to claim 4 , wherein the shield shell is attached to the housing by inserting at least part of the shield shell into the cylindrical fitting portion.

6. The shielded connector according to claim 4 , wherein the shield shell is provided with an escape portion formed by cutting away rearward from a front edge of the shield shell, the escape portion being provided to be fitted over the coupling portion.

7. The shielded connector according to claim 4 , wherein the body portion is provided with a retaining portion that projects from the body portion, and

wherein the shield shell is provided with an elastic retaining piece integrally formed therewith, the elastic retaining piece being provided to be retained to the retaining portion.

8. The shielded connector according to claim 4 , wherein the shielded shell is provided with an elastic contact piece integrally formed therewith, the elastic contact piece being provided to be in contact with an outer circumferential surface of a hood portion of a mating connector.

9. The shielded connector according to claim 4 , wherein the housing is provided with a lever to engage connection between the mating connector and the housing.

10. The shielded connector according to claim 4 , wherein the housing comprises a female terminal.
