Abstract

This invention provides a method for processing ends of coaxial cables and apparatus for processing the ends of the coaxial cables, which can perform end processing against extremely fine coaxial cables at high speed and with accuracy. This invention utilizes first and second cutting blades (11), (12) respectively having cutting edges (11a), (12a) which contact each other when brought towards each other to strip and hence expose the end of a coaxial cable (1) without producing residual cut portions. Therefore, the end of the coaxial cable 1 having an insulation skin (5) or insulation body (3) with a relatively small thickness can be accurately and speedily stripped to expose an inner conductor (2) and an outer conductor (4). Furthermore, a twisting mechanism (20) is used to twist the outer conductor (4) exposed on the outer surface of the insulation body (3). Therefore, the exposed portions of the outer conductor (4) and the inner conductor (2) can be spaced apart along the axial direction of the coaxial cable (1) to positively prevent short circuits therebetween.

However, the coaxial cable shown in Fig. 13 has an inner conductor 2 made up of a large number of core wires. @On the outer surface of the insulator 3 covering the inner conductor 2 for insulation, the same as the coaxial cable! The outer conductor 4 formed by a plurality of wires whose axes extend in parallel is arranged on the entire circumference in the circumferential direction, and the conductor 3 is covered and insulated by a cylindrical insulating sheath 5. If you want to connect to an electronic device with a structure like this] When you want to connect to an electronic device, 'the insulator 3 and the insulating sheath 5 should be removed to a predetermined length ^ The terminal treatment of the internal conductor 2 and the external conductor 4 should be exposed, and ^ .

Creation description (2) After the coaxial cable is rotated, and the entire end of the coaxial cable is cut into the inlet, the end treatment method of the insulation sheath 5 and the insulator 3 can be peeled off. In addition, a laser light is used to cut the insulation sheath 5 and insulator 3 into the end of the inlet. The problem to be solved by the present invention is to use a pair of V-shaped cutting blades to peel off the ends of the coaxial cable in order to produce a cutting residue on the insulation sheath and the insulator. At this time, on the end treatment of the coaxial cable with a certain outer diameter, the insulation sheath or insulator with the remaining cutting part will be displaced in the axial direction of the coaxial cable, that is, the remaining cutting part will break Therefore, the insulation sheath or the cut part of the insulator can be removed without obstruction and exposed (peeled off). However, for extremely thin coaxial cables with an outer diameter of 丨 mm or less, the thickness of the body of the insulator or the insulation sheath (thickness) is thin. Therefore, the insulation sheath and the insulator will produce the original one pair of V. Type cutting knives cannot be used for end processing. Also, the method of processing a pair of V-shaped cutting edges around the coaxial cable and rotating the coaxial coaxially will not cause the insulation sheath and the insulator to cut off the remaining parts of the cog, but it will take time in operation. Therefore, it is not suitable for high-speed terminal processing. Moreover, although the end-of-line processing method using laser light can cut the insulation sheath and the insulator, the process of peeling off the cut part in the axial direction of the coaxial cable is another project.
