Abstract
A limited bend transmission cable for coaxial microwave cables which also has controlled movement under torque. A coaxial microwave transmission line of choice is covered by successive layers of helically-wound armor sheath, hard wire located in the groove of the sheath to aid in control of bend of the cable, a hard wire or braid, insulation, and strain relief boot.
Claims10
A crush resilient flexible transverse electromagnetic mode transmission cable having a controlled bend radius and controlled twist movement under torque, comprising:
- (a) a microwave coaxial transmission line;
- (b) a flexible crush-resilient helically-wound metallic armor sheath having interlocking edges and grooves between its joints, in which said microwave coaxial transmission line is sheathed;
- (c) a metallic wire of a diameter selected to cooperate with the armor in the control on the bend of the cable spirally wound into the groove between the joints of the armor;
- (d) a braided high tensile strength wrap surrounding the armor and the wire;
- (e) an insulating jacket surrounding said braided wrap;
- (f) a strain relief boot surrounding and affixed to the insulating jacket at each end of the cable;
- and
- (g) a connector end for fixation of connectors for the microwave transmission line to said strain relief boot and the microwave transmission line at each end of the cable, for joining the transmission cable to a transmission receiving apparatus.
