BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat cable insulation stripping tool.

[0002]

2. Description of the Related Art In recent years, attention has been paid to the characteristic of low impedance, and flat cables have been frequently used in high-rise buildings and the like. In this flat cable, a plurality of conductors 1 are arranged horizontally as shown in FIG. 3, an outer layer of which is covered with an insulator 2 made of, for example, cross-linked polyethylene, and an outer layer of which is covered with a vinyl sheet 3. Be composed. In such a flat cable 4, for example, if the conductor 1 has a sectional area of 400 mm ² and a withstand voltage of 600 V, the insulator 2
Is 2.5 mm thick and vinyl sheet 3 is 2.3 m thick
m, the cross-sectional area is 500 mm ² and the withstand voltage is 600 V, the thickness of the insulator 2 is 3.0 mm, and the thickness of the vinyl sheet 3 is 2.5 mm, which is about 5 mm in total. For this reason, it takes a considerable amount of time to make a cut in the vinyl sheet 3 and the insulator 2 with a knife or the like at the time of wiring work and to peel off the cut from the cut.

Therefore, Japanese Utility Model Application No. 1-1206 (Japanese Utility Model Application No.
As disclosed in Japanese Patent Application Laid-Open No. 2-1909) , a pair of blades having a blade shape in which a plurality of arcs having an outer diameter corresponding to the outer diameter of an inner conductor of a flat cable are connected, and one ends of which are openably and closably connected. There is a flat cable tapping tool provided with a gripping member and a grip at the other end of the holding member.

[0004]

However, in the above-mentioned flat cable tapping tool, the flat cable is sandwiched between a pair of opposed blades by closing a pair of holding members connected at one end to insulate the flat cable. Since a cut edge for peeling is formed in the body, a considerable clamping force must be applied to form a cut edge for peeling, and there is a problem that the usability is poor.

[0005] Further, since the blade shape cannot be replaced, if the blade edge is worn out, the entire tool must be discarded, which is economically wasteful. Furthermore, since a plurality of types of tools must be prepared according to the thickness of the flat cable and the diameter of the conductor, there is a problem that an economic burden becomes extremely large for those who perform wiring work.

[0006] The purpose of the present invention is to be versatile and extremely economical.
And easy to use, with very little power
A cut edge can be formed on the insulator without scratching
