Abstract
A collar assembly for an insulator assembly has first and second members secured together on the insulator assembly. The first member has first and second fastener holes and a first opening. The second member is connected to the first member, and has third and fourth fastener holes aligned with the first and second fastener holes, respectively. A second opening is formed in the second member. The first and second openings are adapted to receive a sealant. A first fastener is inserted through the first and third fastener holes and a second fastener is inserted through the fourth and second fastener holes to secure the first member to the second member on the insulator assembly.
Claims20
A collar assembly for an insulator assembly, comprising:
- a first member having first and second fastener holes, first inner and outer surfaces and a first opening extending between said first inner and outer surfaces;
- a second member connected to said first member, said second member having third and fourth fastener holes aligned with said first and second fastener holes, respectively, second inner and outer surfaces and a second opening extending between said second inner and outer surfaces, said first and second openings being adapted to convey a sealant;
- and
- a first fastener inserted through said first and third fastener holes and a second fastener inserted through said fourth and second fastener holes to secure said first member to said second member.
A method of installing a collar assembly on an insulator assembly, comprising the steps of
- disposing a first member having first and second fastener holes and a first opening on the insulator assembly;
- connecting a second member to the first member on the insulator assembly, the second member having third and fourth fastener holes aligned with the first and second fastener holes, respectively, and a second opening;
- inserting a first fastener through the second and third fastener holes of the first and second members on the insulator assembly;
- inserting a second fastener through the fourth and first fastener holes of the first and second members on the insulator assembly;
- and
- injecting a sealant through the first opening to fill the cavity formed between inner surfaces of the first and second members and an outer surface of the insulator assembly, the first and second openings being in fluid communication with the cavity.
An insulator assembly, comprising:
- a rubber housing having a first end;
- a metal fitting having a first end, said first end of said rubber housing being disposed in said first end of said metal fitting;
- a collar assembly disposed over said first ends of said rubber housing and said metal fitting, said collar assembly having an annular rib engaging a groove proximal said first end of said metal fitting and a lip engaging said rubber housing proximal said first end thereof, a cavity being defined by an inner surface of said collar assembly and an outer surface of said metal fitting and said rubber housing between said annular rib and said lip;
- and
- a sealant injected through said collar assembly to fill said cavity to create a seal between said collar assembly, said metal fitting and said rubber housing.
