Abstract
Abstract Moisture-tight connectors are made from cut lengths of heatshrinkable plastic tubing by shrinking one end of the tubing around a plastic pellet that softens and bonds to it thus forming a seal. An inward constriction is formed in the other end of the tubing by shrinking it over a block that is spaced away from an internal metal sleeve. The constriction is needed to retain a dielectric paste with which the connector is filled.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
119 words
An apparatus for forming a connector of the type comprising a pressure deformable metal sleeve within a shrinkable plastic jacket, said jacket extending beyond said sleeve to provide unsupported first and second tubular extensions of said jacket at both ends thereof, comprising: A. a base, B. a stretcher block, mounted on said base, having a horizontal area approximating the horizontal section through said sleeve, C. a pin projecting upwardly centrally from said block, a. said pin fitting within said sleeve and supporting said sleeve spaced vertically from said block, thereby providing a gap between said block and said sleeve for the formation of a radial constriction upon the shrinking of a plastic jacket over said sleeve and said block.
