Abstract

A conducting path includes a plurality of cables, and a cable clamp for clamping the plurality of cables together. The cable clamp includes a single metal plate molded along a perimeter of the plurality of cables, an attachment flange formed by overlapping both ends of the metal plate, and a cable supporting member for supporting the plurality of cables between the cable supporting member and the metal plate. The cable supporting member includes a coolant passage formed therein for passing a coolant to cool the plurality of cables in a longitudinal direction of the plurality of cables.

Claims

1. A conducting path, comprising:

a plurality of cables; and

a cable clamp for clamping the plurality of cables together,

the cable clamp comprising;

a single metal plate formed along a perimeter of the plurality of cables;

an attachment flange formed by overlapping both ends of the metal plate; and

a cable supporting member for supporting the plurality of cables between the cable supporting member and the metal plate,

wherein the cable supporting member comprises a coolant passage formed therein for passing a coolant to cool the plurality of cables in a longitudinal direction of the plurality of cables.

2. The conducting path according to claim 1, wherein

the plurality of cables comprise three cables arranged in a triangular shape in a cross sectional view thereof,

the metal plate is formed along a perimeter of the three cables,

the cable supporting member is formed to contact all of the three cables, and support the three cables between the cable supporting member and the metal plate, and

the coolant passage is formed at a central part of the cable supporting member.

3. The conducting path according to claim 2, wherein

the cable supporting member is inserted between two of the three cables arranged in a horizontal direction in the cross sectional view, perpendicularly to the horizontal direction and to the longitudinal direction of the two of the three cables arranged in the horizontal direction, and

the cable supporting member is formed to reduce in width toward a forward end in a direction of being inserted between the two of the three cables arranged in the horizontal direction so as to facilitate the insertion.

4. The conducting path according to claim 1, wherein

the plurality of the three cables each comprise an in-cable coolant passage at a center part thereof in the longitudinal direction of the plurality of cables for passing the coolant.

5. The conducting path according to claim 2, wherein

the plurality of the three cables each comprise an in-cable coolant passage at a center part thereof in the longitudinal direction of the plurality of cables for passing the coolant.

6. The conducting path according to claim 3, wherein

the plurality of the three cables each comprise an in-cable coolant passage at a center part thereof in the longitudinal direction of the plurality of cables for passing the coolant.
