Problems solved by technology

[0009] If the wire length to be completed is short, then for Figure 10 It is very difficult to ensure the point of connecting the corresponding mechanism for the method of detecting the scratch of the core body shown in Patent Document 1
In the case of manual stripping operations by means of bench-top wire strippers, the detection method is also inappropriate from a safety point of view

Embodiment Construction

[0042] In the wire stripper of the present invention, the signal applying means may be a buffer circuit that is connected between the electrical signal generator circuit and the signal analyzer circuit and the shielding material of the shielded wire and outputs signals with the same level to The shielding material side of the shielded wire.

[0043] In addition, when an electric signal is applied to the stripping blade and the stripping blade contacts the core wire of the electric wire, the electric signal changes due to the impedance of the core wire. A function is provided to monitor this phenomenon, wherein said function detects contact between the core wire and the stripping blade.

[0044] Further, it is possible to arbitrarily set the timing or period of time when detecting whether the stripping blade touches the core wire and monitor the time such as starting the stripping operation, just before the end of the stripping operation or during the end of the stripping opera...

Abstract

The wire stripper is configured such that the wire stripper includes a signal analyzer circuit 74 that measures, for example, an impedance through stripping blades 27 and 27; in the process of stripping a coating 71 of an electric wire W, when the stripping blades 27 and 27 contact a wire core 70 of the electric wire W, a change in impedance caused by addition of the impedance of the wire core 70 to the stripping blades 27 and 27 is detected; and a buffer circuit 103 that when a contact of the stripping blades 27 and 27 to the wire core 70 is detected, applies a signal having the same level as that of the electric signal to the stripping blades 27 and 27 to the side of a shielding material 101 of a shielded cable 100 for transmitting the electric signal to the stripping blades 27 and 27 or from the stripping blades 27 and 27 so as to reduce or prevent current leakage between a signal line 73 of the shielded cable 100 and a shielding material 101 of the shielded line 100.

Description

technical field [0001] The present invention relates to a wire stripper having a core contact detection function of detecting contact between a core wire of an electric wire and a stripping blade and capable of detecting the core even when the electric wire is cut short. The function of the contact between the wire and the stripping blade; and the wire stripper reduces the attenuation of the signal at the time of detection to improve the detection accuracy. Background technique [0002] There is known a wire coating stripping device (hereinafter may be referred to as a wire stripper) configured such that a stripping blade is fed into the coating of an electric wire and the stripping blade is relatively moved against the electric wire , thereby peeling off (peeling off) a part of the coating. [0003] When stripping the wire coating by such a wire stripper, it is necessary to feed the stripping blade as deeply as possible into the wire coating to make the cutting edge of the...
