Core wire deformation jig and core wire deformation method

A core wire deformation jig for providing bends to a plurality of adjacent core wires which are exposed from an end of a multi-core cable so that tip side portions of the adjacent core wires are spaced and aligned on a predetermined arranging plane, the bends with the adjacent core wires being spread out starting from root sides of their exposed portions to the tip side portions, the core wire deformation jig comprising:

• a first clamping unit for clamping the plurality of adjacent core wires aligned on the arranging plane in a first clamping direction intersecting the arranging plane;
• a separation pin for separating the adjacent core wires from each other, the separation pin being provided moveably in an insertion direction parallel to the first clamping direction so as to be insertable between the adjacent core wires clamped by the first clamping unit to move the adjacent core wires apart from each other;
• and
• a second clamping unit for providing the bends to the core wires by clamping the plurality of core wires, with the separation pin disposed between the adjacent core wires, in a second clamping direction parallel to the arranging plane and intersecting the adjacent core wires and applying a pressure on the adjacent core wires;
• wherein the first clamping unit comprises a pair of clamping portions configured to be arranged interposing the arranging plane between them;
• and
• wherein the second clamping unit also serves as one of the pair of clamping portions of the first clamping unit.

• a first clamping step for clamping with a first clamping unit the adjacent core wires aligned on the arranging plane in a first clamping direction intersecting the arranging plane;
• a separation step for separating the adjacent core wires from each other, the separation pin being inserted between the adjacent core wires clamped with the first clamping unit in an insertion direction parallel to the first clamping direction to move the adjacent core wires apart from each other;
• and
• a second clamping step for providing the bends to the adjacent of core wires by clamping the adjacent core wires with a second clamping unit, with the separation pin disposed between the adjacent core wires, in a second clamping direction parallel to the arranging plane and intersecting the adjacent core wires and applying a pressure on the core wires
• wherein the root sides of the exposed portions of the adjacent core wires are clamped in the second clamping direction in tight contact with each other by a third clamping unit, and
• wherein the separation pin is inserted between the adjacent core wires on a side closer to tip sides of the adjacent core wires than the root sides, while the root sides are clamped by the third clamping unit.
