Wire stripper

Abstract

Provided is a wire stripper having a function of detecting contact between a core wire of an electric wire and a stripping blade and capable of detection even if the electric wire is cut short. The wire stripper is configured such that the wire stripper includes a signal analyzer circuit (74) that measures impedance, eg through the stripping blades (27, 27). In the process of stripping the coating (71) of the electric wire (W), when the stripping blades (27, 27) contact the core wire (70) of the electric wire (W), due to the impedance of the core wire (70) adding to the stripping blade ( 27, 27) impedance changes are detected; and a buffer circuit (103), when detecting stripping blades (27, 27) contact with the core wire (70), said buffering circuit will be connected to the stripping blade (27 , 27) the signal of the level same level of the electrical signal is applied to one side of the shielding material (101) of the shielded cable (100), and the shielded cable (100) is used to transmit the electrical signal to the stripping blade (27, 27 ) or transmit electrical signals from the stripping blades (27, 27) to reduce or prevent current leakage between the signal wire (73) of the shielded cable (100) and the shielding material (101) of the shielded wire (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...

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 wire 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
