Abstract A method for separating a metallic braid from a core wire of a micro coaxial cable during connecting the coaxial cable to a printed circuit board (PCB) is disclosed. The coaxial cable includes a sheath surrounding the metallic braid and the inner conductor. An apparatus for performing the method includes a rotiform brush, a spin shaft extending through the rotiform brush and an electrical motor for driving the spin shaft and the rotiform brush. The rotiform brush includes a circular frame and a plurality of densely arranged hard brushings attached to the frame. The method comprising the following steps: (i) extending the coaxial cable through corresponding hole formed in the PCB; (ii) stripping a predetermined length of the sheath of the coaxial cable to expose the braid; (iii) moving the PCB with the cable towards the rotiform brush until the exposed metallic braid of the coaxial cable gets contact with the brushings; (iv) rotating the rotiform brush to urge the metallic braid and the core wire in the rotating direction and thus separating the braids from the core wire along a tangent direction of the rotiform brush.
In combination, a printed circuit board defining at least one through hole with at least two conductive pads thereabouts, a coaxial cable defined with a core wire enclosed by an metallic braid commonly extending through said through hole, said core wire including an inner conductor enclosed by an insulative jacket, a rotating brush first approaching the printed circuit board and engaging both said core wire and said braid to forcibly deflect both to extend along a tangent direction of rotation of said rotating brush, said rotating brush successively moving away from said printed circuit board to leave both of said core wire and said braid in a nature manner wherein said core wire is farther spaced from said printed circuit board than said braid due to stiffness thereof so as to separate said core wire and said braid from each other.
