Abstract

A termination structure of a cable with a shield layer wherein a part of a jacket of the cable is removed at an end of the cable to expose a part of the shield layer and the exposed part of the shield layer is grounded to a fitting object and the cable is fitted in water-tightness with the fitting object. The termination structure has: a metallic sleeve disposed on the jacket of the cable, the metallic sleeve being covered with the exposed part of the shield layer being folded at an end of the jacket; a cylindrical metal fitting being disposed on the periphery of the folded shield layer and swaged at a fixing section corresponding to the folded shield layer to fix the cable; and a heat-shrinkable tube disposed on the periphery of the cylindrical metal fitting and the jacket.

Claims (26)

1. A termination structure of a cable with a shield layer wherein a part of a jacket of the cable is removed at an end of the cable to expose a part of the shield layer and the exposed part of the shield layer is grounded to a fitting object and the cable is fitted in water-tightness with the fitting object, comprising:

a metallic sleeve disposed on the jacket of the cable, the metallic sleeve being covered with the exposed part of the shield layer being folded at an end of the jacket;

a cylindrical metal fitting comprising a flange section through which the cylindrical metal fitting is secured to the fitting object, the cylindrical metal fitting being disposed on the periphery of the folded shield layer and swaged at a fixing section corresponding to the folded shield layer to fix the cable; and

a heat-shrinkable tube disposed on the periphery of the cylindrical metal fitting and the jacket.

2. The termination structure according to claim 1 , further comprising:

a resin layer formed in a gap between the jacket of the cable and the cylindrical metal fitting to seal the gap.

3. The termination structure according to claim 1 , wherein:

the cylindrical metal fitting comprises an insertion section being inserted into the fitting object and a projection section protruding outside the fitting object,

the projection section is disposed on the periphery of the folded shield layer, and

an insulation layer of the cable exposed without the shield layer is inserted through the insertion section into the cylindrical metal fitting.

4. The termination structure according to claim 2 , wherein:

the cylindrical metal fitting comprises an insertion section being inserted into the fitting object and a projection section protruding outside the fitting object,

the projection section is disposed on the periphery of the folded shield layer, and

an insulation layer of the cable exposed without the shield layer is inserted through the insertion section into the cylindrical metal fitting.

5. The termination structure according to claim 3 , further comprising:

an annular seal disposed on the periphery of the insertion section to seal a gap between the insertion section and the fitting object.

6. The termination structure according to claim 3 , wherein:

the projection section comprises a groove formed on its periphery to engage an end of the heat-shrinkable tube with the groove to fix the tube.

7. The termination structure according to claim 6 , wherein:

the projection section comprises a plurality of the grooves formed on the periphery in an axial direction of the cylindrical metal fitting.

8. The termination structure according to claim 6 , wherein:

the projection section comprises a diameter expansion section formed adjacent to the groove on the periphery to increase a depth of the groove.

9. A termination structure of a cable with a shield layer wherein a part of a jacket of the cable is removed at an end of the cable to expose a part of the shield layer and the exposed part of the shield layer is grounded to a fitting object and the cable is fitted in water-tightness with the fitting object, comprising:

a metallic sleeve disposed on the jacket of the cable, the metallic sleeve being covered with the exposed part of the shield layer being folded at an end of the jacket;

a cylindrical metal fitting comprising a flange section through which the cylindrical metal fitting is secured to the fitting object, and an end section formed in a horn shape that allows an end of the cylindrical metal fitting to open radially from an axis of the cable, the cylindrical metal fitting being disposed on the periphery of the folded shield layer and swaged at a fixing section corresponding to the folded shield layer to fix the cable; and

an embedding seal provided in the end section to seal a gap between the cable and the cylindrical metal fitting.
