Abstract
A crush, kink, and torque resistant, flexible coaxial cable having a closely spaced, spiralled rigid metal wire layer between the outer conductor of the coaxial transmission line and the outer jacket of the cable. Small size light weight, good flexibility with minimum spring-back and excellent crush resistance are provided together with excellent kinking, and torque resistance. This eliminates the need for external ruggedization to protect the electrical properties of the cable.
Claims11
A crush-resistant coaxial cable comprising:
- (a) a coaxial transmission line, including in order an electrically conductive metal signal-transmitting center wire, at least one layer of electric insulating material, and at least one layer of material containing electrically conducting metal;
- (b) a layer of rigid metal wire spiralled around said transmission line at a minimum angle of 45.degree. to the axis of the cable;
- and
- (c) at least one layer of mechanical braid surrounding said transmission line which lies under said rigid metal wire spiral.
