Device and method for forming a notch for stripping wires

A device for forming a notch for stripping, comprising:

• a plurality of cutting mechanisms including a plurality of mechanism parts, with one of the plurality of mechanism parts being associated to each of the plurality of cutting mechanisms, wherein the plurality of cutting mechanisms are configured to be arranged around an electric wire axis of a coated electric wire, wherein the coated electric wire includes a core covered with an insulating layer or covered with the insulating layer and one conductive layer or a plurality of conductive layers, wherein the one conductive layer or the plurality of conductive layers are layered inside the insulating layer, wherein each of the plurality of cutting mechanisms is configured to form one or more notches in the coated electric wire to a specified notch depth starting from an outer circumferential surface of the coated electric wire by means of a respective one of the plurality of mechanism parts,
• wherein each of the plurality of cutting mechanisms includes:
• an electrically conductive cutter blade which is movable in an intersection direction intersecting the outer circumferential surface;
• a contact detecting section including an in-terminal and an out-terminal configured to form an electric circuit to detect a contact between an outermost conductor of the coated electric wire and the cutter blade based on a variable capacitance between the outermost conductor and the cutter blade,
• wherein the outermost conductor is one of the core, the one conductive layer, or a conductive layer of the plurality of conductive layers located closest to the outer circumferential surface in the coated electric wire,
• wherein the variable capacitance depends on movement of the cutter blade;
• and
• a movement mechanism configured to move the cutter blade in the intersection direction, wherein upon detecting the contact by the contact detecting section during movement of the cutter blade, the movement mechanism is configured to adjust a position of the cutter blade in the intersection direction and position the cutter blade to a position corresponding to the notch depth for forming one or more notches therein,
• wherein each mechanism part associated with a respective cutting mechanism is formed by a pair of one movement mechanism and one cutter blade,
• wherein the plurality of mechanism parts of the plurality of cutting mechanisms are configured to be arranged around the electric wire axis, and
• wherein the device further comprises:
• a rotation mechanism configured to rotate the plurality of mechanism parts of the plurality of cutting mechanisms around the electric wire axis and thus extend a plurality of notches in a direction around the electric wire axis in a state of the plurality of cutting mechanisms which have formed the plurality of notches in the coated electric wire, which makes a stripped region corresponding to the notch depth removable.
