Patent ID: 8026452

Claim:
A method of holding an armor layer of an armored cable, having an end arranged to be grounded and held, using a cable coupler, comprising: placing the armor layer on an inclined surface of a sleeve after a cap fastener and a cylindrical housing are provided on said end of the armored cable, inserting a support ring having a smaller inner diameter into the cylindrical housing, and engaging an internal thread, formed in an extension part of the cylindrical housing, with an external thread, formed in an extension part of a support fastener such that the support ring is brought into contact with the armor layer to preliminarily bend the armor layer in a shape in which the armor layer is held by the cable coupler; loosening the extension part of the cylindrical housing from the support fastener so that the support ring, which is in the cylindrical housing, is removed from the cylindrical housing, confirming whether the armor layer is correctly bent and placed on the inclined surface of the sleeve, and moving the support ring backwards; and fitting a fastening ring over the armor layer of the armored cable, and screwing the cylindrical housing to the support fastener again, such that the fastening ring is seated onto a front end of the armor layer and the support ring supports the fastening ring and the armor layer to support the armor layer in a double support structure.
