Abstract
An electrical cable and connector assembly for electrically coupling equipment to a power source, and having an electrical cable with a plurality of power conductors and a pilot conductor releasably coupled to an electrical contact in an electrical connector, so that the pilot conductor releases from the electrical contact of the connector when a mechanical stress or force is applied to the cable. The pilot conductor releases from the contact of the connector prior to damage occurring to the remaining conductors from the stress or force applied to the cable. The power conductors are spirally wrapped about the centrally located pilot conductor so that the power conductors can stretch while the pilot conductor is pulled from its electrical contact upon application of the force or stress on the cable. In another embodiment, a non-conducting line or wire is connected to the ends of one of the conductors so that the stress or force applied to the cable is transmitted to the non-conducting line instead of to any of the conductors. Specifically, the non-conducting line is shorter than the conductors so that when the non-conducting line is stressed, the releasable end of the conductor will disconnect from its contact before stress is transmitted to the conductors.
