Patent ID: 7180003

Claim:
A method for manufacturing an insulator comprising the steps of: a) providing a material that includes a fiber and a polymer; b) shaping the fiber and polymer material so that the material encloses a cavity and forms a body that is provided with an axis, a first end that includes a first outer diameter, and a second end that includes a second outer diameter, c) providing a first connector with a first connector axis that has been cast and machined to include an anchoring surface; d) providing a second connector with a second connector axis that has been cast and machined to include an anchoring surface; e) dimensioning the anchoring surface on the first connector so that the anchoring surface includes a first diameter that is smaller, at least before assembly onto the body, than the first outer diameter; f) dimensioning the anchoring surface on the second connector so that the anchoring surface includes a second diameter that is smaller, at least before assembly onto the body, than the second outer diameter; g) assembling the first connector onto the first end of the body so that, after assembly, the first connector and the body are generally coaxial; h) assembling the second connector onto the second end of the body so that after assembly, the second connector and the body are generally coaxial; i) providing a housing defining element that has been previously shaped to form at least one shed with shield layer portions on each side; j) arranging the body and the housing defining element in relation to each other so that a distance exists between the body and the housing defining element that corresponds to a cylindrical thickness of a shield layer; k) ejecting rubber into the housing defining element so that the rubber forms a housing comprising the shield layer and at least one shed; and l) molding, at least in part, the shield layer portions simultaneously on each side of the shed.
