Abstract
Cable support insulators of the present invention generally have an insulator body having a cable base and a plurality of insulator sheds. The cable base has a ratchet locking mechanism to secure an electrical conductor to the insulator. In preferred embodiments, a cable support insulator is provided that has an insulator body includes a plurality of insulator sheds and a cable base. A locking base is connected to the cable base, and a retaining clamp is pivotally connected to the cable base. The cable base has a front end, a back end, and a seat adapted to receive a conductor cable. The locking base has a front plate having a plurality of ratchet teeth. The retaining clamp has a first retaining arm, a second retaining arm, and a locking blade.
Claims19
A cable support insulator comprising:
- an insulator body, the insulator body comprising a plurality of insulator sheds and a cable base, the cable base having a front end, a back end, and a seat adapted to receive a conductor cable;
- a locking base connected to the cable base, the locking base comprising a front plate having a plurality of ratchet teeth;
- and
- a retaining clamp pivotally connected to the cable base, the retaining clamp comprising a first retaining arm, a second retaining arm, and a locking blade;
- wherein the locking blade of the retaining clamp engages at least one of the ratchet teeth of the locking base when the retaining clamp is in a cable retaining position.
A cable support insulator comprising:
- an insulator body, the insulator body comprising a plurality of insulator sheds and a cable base, the cable base having a front end, a back end having a socket member, and a seat adapted to receive a conductor cable;
- a locking base connected to the front end of the cable base, the locking base comprising a front plate having a plurality of ratchet teeth;
- and
- a retaining clamp pivotally connected to the socket member that has an open position and a cable engaging position, the retaining clamp comprising a first retaining arm, a second retaining arm, and a locking blade that extends transversely from the first retaining arm to the second retaining arm;
- wherein the locking blade engages at least one of the plurality of ratchet teeth when the retaining clamp is in the cable engaging position.
A cable support insulator comprising:
- an insulator body having a top end and a bottom end, the insulator body comprising a cable base at the top end of the insulator body and a plurality of insulator sheds spaced on the insulator body below the cable base, the cable base having a front end, a back end having a socket member, and a seat adapted to receive a conductor cable;
- a locking base connected to the cable base, the locking base comprising a front plate having a plurality of ratchet teeth;
- and
- a retaining clamp pivotally connected to the cable base that has an open position and a cable engaging position, the retaining clamp comprising a first retaining arm having a guide that engages the front plate of the locking base when the retaining clamp is in the cable retaining position, a second retaining arm that engages the front plate of the locking base when the retaining clamp is in the cable retaining position, and a locking blade that engages at least one of the plurality of ratchet teeth when the retaining clamp is in the cable engaging position.
