Abstract The disclosure relates to a strain relief boot which, when affixed to an electrical cable and connector, will act in a manner that greatly reduces the stresses transmitted from the cable to the electrical contact, thereby preventing wire breakage and will also be flexible enough so as to allow free movement of said cable when in use so that bending and kinking of the cable does not occur at the cable-boot transition point causing wire breakage. The disclosure is more particularly related to a strain relief boot which may be molded directly onto a prewired electrical connector and cable or as an alternative embodiment may be molded separately for later assembly on the cable and connector at the time they are joined together.
A plastic strain relief boot affixed to an electrical cable and connector in order to transmit transverse and axial forces acting on the cable away from the conductor-connector junction and to limit cable flexing, wherein the hardness of the boot is graduated along the length of the boot, the hardness being greatest adjacent to the connector.
