9. A method for coupling components employed in a downhole environment, comprising:
providing a connector with a sealing system and a retainer system each formed of a shape memory alloy material;
mounting sections of an electrical cable in an installation jig;
positioning the connector onto one section of the electrical cable and joining conductor wires of the sections of the electrical cable to form a coupling;
sliding the connector, with the sealing system and the retainer system, over the coupling; and
applying heat to the connector to activate the shape memory alloy material of the sealing system and of the retainer system to form a sealed connection with each section of the electrical cable able to withstand a predetermined tensile loading.
