Abstract:
An improved method of making a flexible coaxial cable (10) having a dielectric core (12) comprising an inner conductor (14) and a dielectric (16) surrounding the inner conductor (14), and a corrugated outer conductive sheath (18, 20) having a plurality of peaks (22) and valleys (24) of predetermined pitch, comprises the step of substantially simultaneously crimping solely the valleys (24) from at least three angularly spaced directions, such as three equiangularly spaced directions about the longitudinal axis (110) of the outer sheath (18, 20), by using angularly spaced crimping wheels (100, 102, 104) which float to follow the predetermined pitch of the corrugated sheath (18, 20) for embedding the valleys (24) in the dielectric (12, 16) so as to lock the dielectric (12, 16) to the sheath (18, 20) for providing electrical stability for the resultant coaxial cable (10). The depth of at least one of the crimping wheels (100) may be micrometer (108) adjusted with respect to the sheath longitudinal axis (110) for setting the depth of locking. The other crimping wheels (102, 104) may act as guides in conjunction with a guide slot (118) through which the sheath (18, 20) passes during crimping for controlling the degree of freedom of movement of the crimping wheels (100, 102, 104) and sheath (18, 20).
