Abstract

A cable fixing apparatus adapted to be fixed to an end of a cable includes a first sleeve having a first thread portion at a first end of the first sleeve, a second sleeve having a bottom portion with a through hole at first end of the second sleeve, and a clamp mechanism disposed in the second sleeve between the first thread portion of the first sleeve and the bottom portion of the second sleeve. The cable is inserted into the second sleeve and the first sleeve through the through hole in an insertion direction. The second sleeve is threaded onto the first thread portion at a second end of the second sleeve. The clamp mechanism clamps the cable in response to an engagement of the second end of the second sleeve to the first thread portion to prevent the cable from moving in the first sleeve and the second sleeve.

First claim

What is claimed is:

1. A cable fixing apparatus adapted to be fixed to an end of a cable, comprising:
a first sleeve having a first thread portion at a first end of the first sleeve and a holding portion extending from the first thread portion;
a second sleeve having a bottom portion with a through hole at first end of the second sleeve, the cable inserted into the second sleeve and the first sleeve through the through hole in an insertion direction, the second sleeve threaded onto the first thread portion at a second end of the second sleeve;
a seal ring disposed at a portion of the first thread portion engaged with the holding portion; and
a clamp mechanism disposed in the second sleeve between the first thread portion of the first sleeve and the bottom portion of the second sleeve, the clamp mechanism clamping the cable in response to an engagement of the second end of the second sleeve to the first thread portion to prevent the cable from moving in the first sleeve and the second sleeve.

2. The cable fixing apparatus of claim 1 , wherein the cable is an optical cable or an electrical cable.

3. The cable fixing apparatus of claim 1 , wherein the clamp mechanism includes an annular portion sleeved over the cable and a pair of clamp arms each extending from the annular portion in the insertion direction.

4. The cable fixing apparatus of claim 3 , wherein an inner wall of the second sleeve has an annular press protrusion protruding radially inwardly, the press protrusion presses the clamp arms radially inwardly toward each other in response to the engagement of the second end of the second sleeve to the first thread portion to clamp the cable.

5. The cable fixing apparatus of claim 4 , wherein the annular portion has an opening and an inner diameter of the annular portion is variable.

6. The cable fixing apparatus of claim 4 , wherein an inner side surface of each of the clamp arms has a plurality of projections.

7. The cable fixing apparatus of claim 4 , wherein the holding portion has a plurality of receiving grooves into which the clamp arms are inserted to prevent the clamp mechanism from being rotated relative to the first sleeve.

8. The cable fixing apparatus of claim 4 , wherein each of the clamp arms has a wedge feature protruding radially outwardly with respect to the insertion direction.

9. The cable fixing apparatus of claim 8 , wherein the press protrusion has an inclined surface in contact with the wedge feature.

10. The cable fixing apparatus of claim 1 , further comprising a seal member disposed between the clamp mechanism and the bottom portion of the second sleeve, the cable passing through the seal member.

11. The cable fixing apparatus of claim 10 , wherein the seal member has a plurality of steps.

12. A cable connector, comprising:
a cable fixing apparatus adapted to be fixed to an end of a cable, the cable fixing apparatus including a first sleeve having a first thread portion at a first end of the first sleeve and a holding portion extending from the first thread portion, a second sleeve having a bottom portion with a through hole at first end of the second sleeve, a seal ring disposed at a portion of the first thread portion engaged with the holding portion, and a clamp mechanism disposed in the second sleeve between the first thread portion of the first sleeve and the bottom portion of the second sleeve, the cable inserted into the second sleeve and the first sleeve through the through hole in an insertion direction, the second sleeve threaded onto the first thread portion at a second end of the second sleeve, the clamp mechanism clamping the cable in response to an engagement of the second end of the second sleeve to the first thread portion to prevent the cable from moving in the first sleeve and the second sleeve;
a third sleeve having a second thread portion at a first end of the third sleeve, the second thread portion adapted to be engaged with the second end of the first sleeve; and
a connector body mounted within the third sleeve, the end of the cable is connected to the connector body.

13. The cable connector of claim 12 , wherein the third sleeve has a lock mechanism extending from the second thread portion and holding the first sleeve on the third sleeve when the first sleeve is threaded with the third sleeve.

14. The cable connector of claim 13 , wherein the lock mechanism has a cantilever extending from the second thread portion towards the first sleeve and a lock protrusion disposed on the cantilever and protruding outwardly.

15. The cable connector of claim 14 , wherein the first sleeve has a lock groove engaged with the lock protrusion.

16. An electrical device, comprising:
a cable connector including:
a cable fixing apparatus adapted to be fixed to an end of a cable, the cable fixing apparatus including a first sleeve having a first thread portion at a first end of the first sleeve and a holding portion extending from the first thread portion, a second sleeve having a bottom portion with a through hole at first end of the second sleeve, a seal ring disposed at a portion of the first thread portion engaged with the holding portion, and a clamp mechanism disposed in the second sleeve between the first thread portion of the first sleeve and the bottom portion of the second sleeve, the cable inserted into the second sleeve and the first sleeve through the through hole in an insertion direction, the second sleeve threaded onto the first thread portion at a second end of the second sleeve, the clamp mechanism clamping the cable in response to an engagement of the second end of the second sleeve to the first thread portion to prevent the cable from moving in the first sleeve and the second sleeve;
a third sleeve having a second thread portion at a first end of the third sleeve, the second thread portion adapted to be engaged with the second end of the first sleeve; and
a connector body mounted within the third sleeve, the end of the cable is connected to the connector body; and

a mating connector including a shield housing and an electronic module mounted within the shield housing, the electronic module coupled with the cable connector inserted into the shield housing.

17. The electrical device of claim 16 , further comprising a mounting panel on which the third sleeve is mounted.
