Cable Strain Relief through Shrinkable Tubing and Notched Encapsulation

A coaxial cable is connected to a tuning-fork connector that has a notch in its encapsulation that helps to hold a link of heat shrunk tubing that provides strain relief.

The tuning form connectors are described in various patents and publications including U. S. Patent 3,673,542. When a high speed triaxial cable is used with this connector, it is necessary to provide a strain relief for the cable.

The drawing shows the tuning-fork connector 2, its encapsulation 3, a triaxial cable 4, and a strain relief 5. A length 6 of the outer insulation of the cable is removed to expose a length of inner insulation 7 between the end of the connector encapsulation 3 and the fully insulated cable. This length of reduced mechanical rigidity provides a measure of strain relief, but it exposes the relatively fragile drain wire to sharp bends and potential breakage. A length of heat-shrinkable tubing spanning the cable and the tuning-fork encapsulation protects this bare wire from severe bending and adds tensile resistance to the total cable connector assembly. When the tubing shrinks, it grips the notch 8 in the connector encapsulation 3 so that the tubing is held in position.
