Abstract

A cable splice includes a casing, a guide, and a pilot cup. The casing has a first opening and an interior cavity. The guide includes a receiving end and a shaft extending at least partially into the interior cavity. The pilot cup is integrally formed with the guide and frangibly connected to the shaft. The cable splice may also include a clamp positioned in the interior cavity and moveable between a loading position and a terminated position. A biasing member urges the clamp into the terminated position. During movement of the clamp from the loading position to the terminated position, the clamp contacts the guide causing at least a portion of the shaft to exit the interior cavity. The guide may also include a rib and a slot allowing the guide to fit in casings having different sized interior cavities.

First claim

What is claimed is:

1. A method for electrically connecting a conducting cable to a splice, the method comprising:
positioning at least a portion of a shaft of a guide within a casing such that a cup coupled to an inner end of the shaft is positioned within a clamp, the clamp biased toward an opening of the casing;
inserting an end of the conducting cable through the guide and into the cup;
separating the cup from the inner end of the shaft by exerting pressure on the cup through the conducting cable; and
after separation of the cup and the inner end of the shaft, further inserting the conducting cable through the guide to move the cup through the clamp, permitting the clamp to move toward a terminal position in which the clamp securely engages the conducting cable.

2. The method of claim 1 , wherein permitting the clamp to move toward a terminal position causes the clamp to contact the inner end of the shaft and move a portion of the shaft through the opening of the casing.

3. The method of claim 2 , further comprising retaining the shaft against complete removal from the casing by a stop engaging an inner surface of the casing.

4. The method of claim 1 , wherein positioning at least a portion of the shaft includes positioning the cup between at least two jaw members to prevent the jaw members from moving toward the opening of the casing.

5. The method of claim 1 , wherein positioning at least a portion of the shaft includes positioning the cup between at least two jaw members to prevent the jaw members from moving radially inward toward one another.

6. The method of claim 1 , wherein separating the cup from the inner end of the shaft includes rupturing a frangible connection formed by a plurality of projections extending between the inner end of the shaft and the cup.

7. The method of claim 1 , wherein, when the cup is positioned in the clamp, the clamp is biased toward the opening of the casing by a biasing member.

8. The method of claim 1 , wherein, after the cup has moved through the clamp, the clamp is biased toward the opening of the casing by a tension in the conducting cable.

9. The method of claim 1 , wherein positioning at least a portion of the shaft includes compressing a portion of the shaft to permit a portion of the shaft to pass through the opening of the casing.

10. A method for electrically connecting a conducting cable to a splice, the method comprising:
positioning at least a portion of a shaft of a guide within a casing such that a cup coupled to an inner end of the shaft is positioned within a clamp, the clamp biased toward an opening of the casing;
inserting an end of the conducting cable through the guide and into the cup;
separating the cup from the inner end of the shaft by rupturing a frangible connection between the shaft and the cup; and
after separation of the cup and the inner end of the shaft, further inserting the conducting cable through the guide to move the cup through the clamp, permitting the clamp to move toward a terminal position in which the clamp securely engages the conducting cable.

11. The method of claim 10 , wherein permitting the clamp to move toward a terminal position causes the clamp to contact the inner end of the shaft and move a portion of the shaft through the opening of the casing.

12. The method of claim 11 , further comprising retaining the shaft against complete removal from the casing by a stop engaging an inner surface of the casing.

13. The method of claim 10 , wherein positioning at least a portion of the shaft includes positioning the cup between at least two jaw members to prevent the jaw members from moving toward the opening of the casing.

14. The method of claim 10 , wherein positioning at least a portion of the shaft includes positioning the cup between at least two jaw members to prevent the jaw members from moving radially inward toward one another.

15. The method of claim 10 , wherein the frangible connection is formed by a plurality of projections extending between the inner end of the shaft and the cup.

16. A method for electrically connecting a conducting cable to a splice, the method comprising:
positioning a cable splice to receive a conducting cable, the cable splice including a casing having an opening and an interior cavity at least partially defined by an interior wall, a clamp positioned in the interior cavity and moveable between a loading position and a terminal position, a biasing member biasing the clamp toward the terminal position, a guide including a shaft extending through the opening of the casing and a stop extending from the shaft toward the interior wall, the shaft including a receiving end and an inner end opposite the receiving end, and a pilot cup connected to the shaft by a frangible coupling, the pilot cup holding the clamp in the loading position against a force of the biasing member;
inserting an end of the conducting cable through the guide and into the cup;
separating the cup from the inner end of the shaft by rupturing the frangible coupling between the shaft and the cup; and
after separation of the cup and the inner end of the shaft, further inserting the conducting cable through the guide to move the cup through the clamp, permitting the clamp to move toward a terminal position in which the clamp securely engages the conducting cable.

17. The method of claim 16 , wherein the frangible connection is formed by a plurality of projections extending between the inner end of the shaft and the cup.

18. The method of claim 16 , wherein during movement of the clamp from the loading position to the terminal position, the clamp contacts the guide causing a portion of the shaft to pass through the opening.

19. The method of claim 18 , wherein the stop prevents the shaft from completely exiting the interior cavity though the opening.

20. The method of claim 19 , wherein the stop wherein the stop encircles the shaft.
