The patent US11996215B2 describes a metal sheath designed for housing multiple conductors, characterized by its unique structural configuration. The sheath is formed from a continuous strip of metal that is wound into a series of revolutions along a lengthwise axis. Each revolution includes a first section with a semicircular profile that extends into the interior cavity of the sheath, a second section that runs parallel to the lengthwise axis and is longer than the diameter of the first section, and a third section that interlocks with an adjacent revolution. The design incorporates specific inflection points where the sections connect, ensuring a compact and efficient arrangement. Notably, the length of the second section is at least three times the distance between certain inflection points when the sheath is in a linear configuration.

Additionally, the claims outline variations of the metal sheath, emphasizing the helical and convoluted arrangements of the metal strip. Each configuration maintains the essential features of the semicircular profile and the proportional relationships between the sections. The patent also specifies that the diameter of the first section must exceed the distance between specific inflection points, further enhancing the interlocking capability of adjacent revolutions. This innovative design aims to improve the structural integrity and functionality of the metal sheath, making it suitable for various applications involving conductor housing.
