Abstract

A cable splice for overhead power transmission lines includes a flexible housing. A first casing is positioned in the flexible housing. The first casing is configured to receive and retain a first conductor. A second casing is positioned in the flexible housing. The second casing is configured to receive and retain a second conductor. A connecting member is connected to the first casing and the second casing. The first casing is moveable relative to the second casing.

First claim

The invention claimed is:

1. A cable splice for overhead power transmission lines comprising:
a flexible housing comprising a plurality of cables forming a first section, a second section, and a central section positioned between the first and second sections, wherein the central section is narrower than the first section and the second section;
a coupling positioned at a first end of the flexible housing, the coupling having a plurality of openings respectively receiving the plurality of cables;
a first casing positioned in the first section of the flexible housing, the first casing configured to receive and retain a first conductor;
a first end cap positioned in the flexible housing;
a second casing positioned in the second section of the flexible housing, the second casing configured to receive and retain a second conductor;
a second end cap positioned in the flexible housing; and
a connecting member connected to the first casing and the second casing,
wherein the first casing is moveable relative to the second casing, and
wherein the first end cap is formed separately from and securely engages both the first casing and the connecting member and the second end cap is formed separately from and securely engages both the second casing and the connecting member.

2. The cable splice of claim 1 , wherein the connecting member is flexible.

3. The cable splice of claim 1 , wherein the connecting member electrically connects the first casing and the second casing.

4. The cable splice of claim 1 , wherein a first jaw assembly and a first biasing member are positioned in the first casing and a second jaw assembly and a second biasing member positioned in the second casing.

5. A cable splice for overhead power transmission lines comprising:
a plurality of cables forming a flexible housing including a first section, a second section, and a central section positioned between the first and second sections, wherein the central section is narrower than the first section and the second section;
a first casing positioned in the first section of the flexible housing, the first casing configured to receive and retain a first conductor;
a first end cap positioned in the flexible housing;
a second casing positioned in the second section of the flexible housing, the second casing configured to receive and retain a second conductor;
a second end cap positioned in the flexible housing; and
a connecting member connected to the first casing and the second casing,
wherein the first casing is moveable relative to the second casing, and
wherein the first end cap is formed separately from and securely engages both the first casing and the connecting member and the second end cap is formed separately from and securely engages both the second casing and the connecting member.

6. The cable splice of claim 5 , wherein the plurality of wound cables form a resilient housing.

7. The cable splice of claim 5 , wherein the connecting member is a flexible cable.

8. The cable splice of claim 5 , wherein a first jaw assembly and a first biasing member are positioned in the first casing and a second jaw assembly and a second biasing member positioned in the second casing.

9. The cable splice of claim 5 , further comprising a coupling positioned at a first end of the flexible housing, the coupling having a plurality of outer openings respectively receiving the plurality of cables.

10. The cable splice of claim 9 , wherein the coupling includes a central opening for receiving the first conductor.

11. The cable splice of claim 9 , further comprising a ferrule connected to each cable.

12. A cable splice for overhead power transmission lines comprising:
a plurality of cables forming a flexible housing including a first section, a second section, and a central section positioned between the first and second sections, wherein the central section is narrower than the first section and the second section;
a coupling positioned at a first end of the flexible housing, the coupling having a plurality of outer openings respectively receiving the plurality of cables;
a first casing positioned in the first section of the flexible housing and having a first interior cavity and a first opening for receiving a first conductor;
a first end cap positioned in the flexible housing;
a first jaw assembly moveably positioned in the first interior cavity for retaining the first conductor in the first casing;
a second casing positioned in the second section of the flexible housing and having a second interior cavity and a second opening for receiving a second conductor;
a second end cap positioned in the flexible housing;
a second jaw assembly moveably positioned in the second interior cavity for retaining the second conductor in the second casing;
a connecting member connected to the first casing and the second casing,
wherein the first casing is moveable relative to the second casing and the connecting member provides an electrical connection between the first conductor and the second conductor, and
wherein the first end cap is formed separately from and securely engages both the first casing and the connecting member and the second end cap is formed separately from and securely engages both the second casing and the connecting member.

13. The cable splice of claim 12 , wherein the plurality of cables are wound in a spiral configuration.

14. The cable splice of claim 12 , wherein a first biasing member is positioned in the first casing to bias the first jaw assembly toward the first opening.

15. The cable splice of claim 12 , wherein the connecting member is flexible.
