Splice restraint and mating indicator
View Patent ↗The present invention relates to a splice restraint for use with sleeves that attach to joints. The splice restraint includes a first securing member constructed and arranged to be received in a groove of a first sleeve that is installable on a first leg of a joint, a second securing member constructed and arranged to be received in a groove of a second sleeve that is installable on a second leg of the joint, and a strap connecting the first securing member to the second securing member. The strap having a length determined by the distance between the groove on the first sleeve and the groove on the second sleeve when the first and second sleeves are properly installed on the joint. The splice restraint provides a visual indication that the sleeves are properly installed on the joint, as well ensures that sleeves will not be displaced after the lineman leaves the site.
1. A splice restraint for use with sleeves that attach to electrical joints in an electrical power distribution system, the splice restraint comprising:
a first securing member configured to engage a first sleeve installable on a first leg of a joint at a first point, the first securing member extending around the entire circumference of the first groove and further comprising a tightening device for tightening the first securing member to the first sleeve;
a second securing member configured to engage a second sleeve installable on a second leg of said joint at a second point; and
a strap connecting the first securing member to the second securing member, the strap having a length determined by the distance between the first point on the first sleeve and the second point on the second sleeve when the first and second sleeves are properly installed on the joint;
wherein the first point is within a groove formed in the first sleeve, and the second point is within a groove formed in the second sleeve.
2. The splice restraint of claim 1 further comprising a second strap connecting the first securing member to the second securing member, the second strap having a length determined by the distance between the first point on the first sleeve and the second point on the second sleeve when the first and second sleeves are properly installed on the joint.
3. The splice restraint of claim 1 , wherein the strap comprises a grounding eye.
4. The splice restraint of claim 1 , wherein the tightening device comprises a worm gear.
5. The splice restraint of claim 1 , wherein the second securing member extends around the entire circumference of the second groove and further comprises a tightening device comprising a worm gear for tightening the second securing member to the second sleeve.
6. The splice restraint of claim 1 , wherein the strap connects to an inner side of the first securing member such that the strap is sandwiched between the first securing member and the first sleeve when the first securing member engages with the first sleeve.
7. The splice restraint of claim 1 , wherein the second securing member is configured to be flexible enough to expand around and into at least a portion of the groove when sufficient pressure is applied and resilient enough to hold the first and second sleeves onto the joint without a tightening device.
8. The splice restraint of claim 1 , wherein the first point is proximate a raised member formed in the first sleeve.
9. The splice restraint of claim 1 , wherein the second point is proximate a raised member formed in the second sleeve.
10. The splice restraint of claim 1 , wherein the first point is an end of the first sleeve distal a cable end of the sleeve.
11. The splice restraint of claim 1 , wherein the second point is at an end of the second sleeve distal a cable end of the sleeve.
