Superior seal for overmolded assemblies

A method for sealing a cable to an overmold assembly using a sealing material, the method comprising:

• providing a cable comprising a cable material having a first coefficient of thermal expansion (CTE);
• applying a sealing material to the cable, the sealing material having a third CTE;
• and
• applying an overmold on top of the sealing material, the overmold comprising an overmold material having a second CTE, the overmold configured to compress the sealing material against the cable and form a seal between the cable and the overmold;
• wherein
• the first CTE of the cable material is different than the second CTE of the overmold material.

An apparatus comprising:

• a cable;
• a cable jacket disposed on the cable;
• a sealing material disposed about the cable jacket;
• and
• an overmold disposed around the sealing material and the cable jacket;
• wherein
• the sealing material has a coefficient of thermal expansion (CTE) selected to create a seal between the cable jacket and the overmold and prevent environmental ingress between the cable jacket and the overmold over a range of operating temperatures.
