Split, non-metallic electrical insulating bushing
View Patent ↗A split, non-metallic electrical insulating bushing for placement on a terminating end of an electrical conduit, the bushing rotatable between a first open configuration and a second closed configuration and having first and second hemispherically shaped bushing portions. Both bushing portions have a first end and a second end. The first ends are dimensioned to rotate with respect to each other. The second end of the first bushing portion has a projecting clasp member with a hook portion, while the second end of the second bushing portion has a recess dimensioned for receipt of the projecting clasp member. The clasp member is angled relative to the recess so that the hook portion contacts the second bushing portion so as to align the first and second bushing portions as the clasp member enters the recess. The hook portion then extends through the recess to secure the bushing in its closed configuration.
1. A split, non-metallic electrical insulating bushing for placement on a terminating end of an electrical conduit, the bushing rotatable between a first open configuration and a second closed configuration comprising:
a first electrical insulating bushing portion having a substantially hemispherical shape with a first end and a second end, the first bushing portion including a rim,
a second electrical insulating bushing portion having a substantially hemispherical shape with a first end and a second end, the first end dimensioned to rotate with the first end of the first insulating bushing portion, the second bushing portion including a rim, and
means for allowing the first end of the first insulating bushing portion and the first end of the second insulating bushing portion to rotate with respect to each other,
wherein the second end of the first insulating bushing portion comprises a projecting clasp member,
wherein the second end of the second insulating bushing portion has a recess formed therein dimensioned for receipt of the projecting clasp member,
wherein the projecting clasp member has a hook portion, the hook portion having a surface angled relative to the recess when the first insulating bushing portion and second insulating bushing portion are rotated toward each other so as to align the second ends of the first insulating portion and the second insulating portion with respect to each other as the hook portion contacts a surface of the second insulating bushing portion forming said recess,
wherein the hook portion further extends through said recess so as to secure the bushing in its second closed configuration, and
wherein one end of the first insulating bushing portion has a seam cover that is dimensioned to overlie a gap between said end and the corresponding end of the second insulating bushing portion when the bushing is in the second closed configuration and wherein the second insulating bushing portion includes a seam cover that is dimensioned to overlie a gap between its other end and the corresponding other end of the first insulating bushing portion when the bushing is in the second closed configuration.
2. The split, non-metallic insulating bushing according to claim 1 , wherein the hook portion includes an underlying surface for snap secure engagement with the surface of the second insulating bushing portion forming said recess.
3. The split, non-metallic insulating bushing according to claim 1 , wherein the second end of the first insulating portion further comprises a projecting pin and wherein the second end of the second insulating portion further has an orifice formed therein dimensioned for receipt of the projecting pin when the split, non-metallic insulating bushing is in its second closed configuration, thereby providing enhanced securement of the split non-metallic insulating bushing when in the second closed configuration.
4. The split, non-metallic insulating bushing according to claim 1 , wherein the first bushing portion has a flange attached to the rim that projects radially inward so as to overlie the terminating end of an electrical conduit when installed thereon and wherein the second bushing portion has a flange attached to the rim that projects radially inward so as to overlie the terminating end of an electrical conduit when installed thereon.
5. The split, non-metallic insulating bushing according to claim 1 , wherein the rim of the first insulating bushing portion and the rim of the second insulating bushing portion each include threads formed on an interior surface thereof, said threads dimensioned for threading engagement with threads formed on a terminating end of an electrical conduit.
6. The split, non-metallic insulating bushing according to claim 1 , wherein the first end of the first insulating bushing portion and the first end of the second insulating bushing portion are rotatably secured to each other by a hinge pin.
7. The split, non-metallic insulating bushing according to claim 6 , wherein the hinge pin is fabricated from zinc plated steel.
8. The split, non-metallic insulating bushing according to claim 1 , wherein the rim of the first insulating bushing portion and the rim of the second insulating bushing portion end each include a plurality of ribs dimensioned to assist gripping the bushing.
9. The split, non-metallic insulating bushing according to claim 1 , wherein the first insulating bushing portion and the second insulating bushing portion are formed from a thermoplastic material.
