Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a method for removing an insulator from the outside of a microwave rigid type high frequency coaxial cable.

(Prior art) Conventional coaxial cable terminal processing involves fixing the coaxial cable with a chuck such as a lathe and rotating it while advancing a cutting tool from a direction perpendicular to the coaxial cable until the cutting tool reaches the center conductor. The method used was to cut the insulator and then remove the cut external conductor and insulator by pulling them in the axial direction.

Termination processing using this method requires rotating the coaxial cable to be terminated, so depending on the length and shape of the coaxial cable, termination treatment may not be possible. There are drawbacks such as damage to the center conductor as the knife cuts toward the center conductor.

(Object of the Invention) An object of the present invention is to provide a coaxial cable terminal processing method that improves the above-mentioned drawbacks.

(Structure of the Invention) In a coaxial cable terminal processing method, the present invention provides a plurality of cutting blades that can be cut by rotational movement of the cylindrical metal member on the end face of the cylindrical metal member, and a portion located at the center of the coaxial cable. While rotating a cutter that made a hole #1 approximately matching the required length and diameter of the center conductor,
The cutting edge surface of the cutter is pressed so that the center conductor of the coaxial cable and the center of the cutter hole are concentric with each other.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

Figure 1 is a sectional view showing the structure of a coaxial cable. Figure 1 (a) shows the shape before terminal processing, and Figure 1 (b)
) indicates the shape after terminal processing.

FIGS. 2(a) and 2(b) are a side view and a front view showing the shape of the cutter.

The cutter 2 has a plurality of cutting blades 2a and a hole 2a for the center conductor IC of the coaxial cable 1, and
It has a structure in which a plurality of chips are provided with a plurality of chips to release chips generated by cutting the external conductor 1a and the insulator 1b.

An embodiment of the present invention will be described with reference to FIG.

In FIG. 3, a coaxial cable holder 3 and a cutter holder 4 are auxiliary tools necessary for rotating the cutter 2 concentrically with respect to the coaxial cable 1.

First, as a preparatory work, attach the cutter 2 to the cutter holder 4.
Further, the coaxial cable 1 is fixed to the coaxial cable holder 3 so as not to move in the axial direction and the internal direction. For terminal processing, hold the coaxial cable holder 3, move the cutter holder 4 in the direction of the coaxial cable holder 3 so that the coaxial cable 1 and cutter 2 are concentric, and rotate the cutter holder 4. Press it against the end face of the coaxial cable l until it takes the shape shown in Figure 1.

(Effects of the Invention) According to the present invention, terminal processing can be easily performed without using a machine tool such as a lathe. In addition, there are fewer restrictions on the length and shape of the coaxial cable, making it suitable for application 1.
The area is enlarged, and the terminal can be processed without giving a phase to the center conductor.
