Abstract

A shielded connector which can reduce production costs and prevent displacement of a shield wire is provided. The corrugated holder of the shielded connector is made up of a pair of half covers 36. Each half cover is provided with an outer cover and an inner cover. A case insertion chamber for a wire attachment case is formed between the outer cover and the inner cover. A wire stopper for the shield wire is formed at one end of the inner surface of the inner cover. A plurality of tube insertion grooves for a corrugated tube are formed at the other end of the inner surface of the inner cover. The outer cover is provided with a cover securing portion corresponding to the outer wall of the wire attachment case. The sheath of the shield wire is provided with a sheath holding ring for radially compressing the sheath.

Claims

1. A shielded connector comprising:

a connector terminal connected to an end of a shield wire;

a wire attachment case, arranged for securement to an attachment opening of a casing of electric equipment to accommodate and protect the shield wire;

a corrugated holder attached to a wire insertion side of the wire attachment case;

corrugated tube connected to the wire insertion side of the wire attachment case via the corrugated holder to protect the shield wire;

said corrugated holder having a pair of half covers facing to each other, each of the half covers being provided with an outer cover portion and an inner cover portion;

a case insertion chamber disposed between the outer cover portion and the inner cover portion on the wire insertion side of the wire attachment case;

a wire stopper for the shield wire at one end of an inner surface of the inner cover portion;

a plurality of tube insertion grooves engaged with the corrugated tube at the other end of the inner surface of the inner cover portion; and

a cover securing portion corresponding to an outer wall of the wire attachment case, the cover securing portion being provided to the outer cover portion.

2. The shielded connector according to claim 1, wherein

a sheath holding ring is provided to a sheath of the shield wire to compress the sheath in the radial direction.

3. The shielded connector according to claim 2, wherein

the sheath holding ring has a small caulking portion and a large stopper with a step portion, and

an open rim of the large stopper has a diameter large enough to interfere with the wire stopper of the corrugated holder.

4. The shielded connector according to claim 1, wherein

a rubber stopper which can be engaged with the wire stopper is attached to the shield wire.

5. The shielded connector according to claim 4, wherein

the wire stopper is held between the sheath holding ring and the rubber stopper attached to the shield wire.

6. The shielded connector according to claim 1, wherein

the wire stopper is made up of a plurality of protrusions situated at equal intervals and protruding toward the axis of the corrugated holder.

7. The shielded connector according to claim 1, wherein

the wire stopper is a ring-like protrusion for holding the shield wire.

8. The shielded connector according to claim 1, wherein

an inner coating of the shield wire extends from an opening at the connector terminal connecting side of the wire attachment case, and

the inner coating is provided with an inner coating holding ring having a flange which is capable of interfering with the opening at the connector terminal connecting side of the wire attachment case.

9. The shielded connector according to claim 8, wherein

the inner coating holding ring also serves as a stopper to prevent a shell member having electrical continuity to the braid of the shield wire from moving toward the connector terminal side of the wire attachment case.

10. The shielded connector according to claim 8, wherein

the inner coating holding ring is made of an insulating material.

11. The shielded connector according to claim 9, wherein

the inner coating holding ring is made of an insulating material.

12. A shielded connector comprising:

a connector terminal connected to an end of a shield wire, an inner case for accommodating and securing the connector terminal;

an outer case for covering the inner case and the end of the shield wire, the outer case being connected to a mating connector;

a corrugated holder attached to a wire insertion side of the outer case;

a corrugated tube for protecting the shield wire connected to the wire insertion side of the outer case via the corrugated holder;

said corrugated holder having a pair of half covers facing to each other,;

an outer cover portion and an inner cover portion provided to each of the half covers;

a case insertion chamber between the outer cover portion and the inner cover portion on the wire insertion side of the outer case;

a wire stopper for the shield wire provided at one end of an inner surface of the inner cover portion;

a plurality of tube insertion grooves for engaging the corrugated tube at the other end of the inner cover portion; and

a cover securing portion corresponding to an outer wall of the outer case, the outer securing portion being provided to the outer cover portion.

13. The shielded connector according to claim 12, wherein the shield wire is provided with a sheath holding ring which radially compresses the sheath.

14. The shielded connector according to claim 13, wherein

the sheath holding ring comprises a small caulking portion and a large stopper with a step portion, and

an opening at an end of the stopper has a diameter large enough to interfere with the wire stopper of the corrugated holder.
