Electrical insulator having clamping jaws with separately fabricated liner members
First Claim
1. In an electrical insulator having opposed jaws, at least one jaw being adjustable in relation to the other jaw for clamping an electrical conductor therebetween, the said jaws consisting of plastic pieces which are molded at elevated temperatures and which undergo thermal contraction when cooled subsequent to the molding process, the improvement comprising:
- opposed grooves in the confronting surfaces of said jaws; and
, liner members consisting of a material different from that of said jaws, said liner members being inserted into said grooves while the interior groove dimensions are expanded as a result of the elevated molding temperatures, with the subsequent thermal contraction of the internal groove dimensions during cooling resulting in said liner members being firmly anchored within said grooves.

Abstract
An electrical insulator having opposed jaws with at least one of the jaws being adjustable in relation to the other jaw for clamping an electrical conductor therebetween. The jaws are part of plastic pieces which are molded at elevated temperatures and which undergo thermal contraction when cooled subsequent to the molding process. Opposed grooves are provided in the confronting surfaces of the jaws. Liner members consisting of a material different from that of the jaws are received in the grooves. The liner members are sized for ready insertion into the grooves while the interior groove dimensions are expanded as a result of the elevated molding temperatures. The subsequent thermal contraction of the internal groove dimensions during cooling results in the liner members being firmly anchored within the grooves.
