Abstract

A cable clamp includes a single metal plate shaped along an outer periphery of three cables that are triangularly arranged when viewed in cross-section, a mounting flange portion formed with both end portions of the metal plate overlapped each other, and a cable support member inserted between at least two of the three cables so as to support the at least two cables between itself and the metal plate. The cable support member is inserted between two horizontally arranged cables in a direction perpendicular to the horizontal direction as well as perpendicular to a longitudinal direction of the two horizontally arranged cables. The cable support member has a tapered shape on an end side in an insertion direction thereof for facilitating an insertion thereof into a gap between the two horizontally arranged cables.

Claims

1. A cable clamp, comprising:

a single metal plate shaped along an outer periphery of three cables that are triangularly arranged when viewed in cross-section;

a mounting flange portion formed by both end portions of the metal plate being overlapped together; and

a cable support member inserted between at least two horizontally arranged cables of the three cables so as to support the at least two cables between itself and the metal plate,

wherein the single metal plate comprises a first sandwiching-holding portion for sandwiching and holding the at least two cables in a horizontally-spaced state with two arc-shaped portions formed to include two arcs when viewed in a cross section prior to sandwiching and holding the at least two cables,

wherein the mounting flange portion is formed in a substantially perpendicular direction to a horizontal direction of the two horizontally arranged cables, the perpendicular direction of an extension of the mounting flange portion extending along a line that crosses with a line that connects central axes of the two horizontally arranged cables,

wherein the cable support member is inserted with the mounting flange portion being opened, from an opening of the mounting flange portion, between the two horizontally arranged cables housed in the two arc-shaped portions respectively and held with a space horizontally by the first sandwiching-holding portion, and in a direction perpendicular to a horizontal direction and perpendicular to a longitudinal direction of the two horizontally arranged cables,

wherein the cable support member has a tapered shape on an end side in an insertion direction thereof for facilitating an insertion thereof between the two horizontally arranged cables,

wherein the single metal plate further comprises a second sandwiching-holding portion for sandwiching and holding one cable of the three cables, which is not housed in the two arc-shaped portions of the three cables, and

wherein the first sandwiching-holding portion is formed along an outer periphery of the one cable to have a substantially circular shape when viewed in the cross-section.

2. The cable clamp according to claim 1, wherein the cable support member is formed in a shape to contact all of the three cables and to support the three cables between the cable support member and the metal plate.

3. The cable clamp according to claim 1, further comprising:

a deformation preventing rib extending from a surface of the mounting flange portion opposite to a mounting surface to the metal plate along the outer periphery of the three cables for preventing a deformation of the mounting flange portion.

4. The cable clamp according to claim 1, wherein the cable support member allows the at least two cables to be disposed to directly contact the metal plate such that the at least two cables are supported between the cable support member and the metal plate.

5. The cable clamp according to claim 2, wherein the cable support member allows the three cables to be disposed to directly contact the metal plate such that the three cables are supported between the cable support member and the metal plate.

6. The cable clamp according to claim 1, wherein the cable support member is inserted between the three cables such that the cable support member spaces apart the at least two cables from a third cable of the three cables.

7. The cable clamp according to claim 1, wherein surfaces of said both end portions of the metal plate contact each other to form a plate-like shape.

8. The cable clamp according to claim 1, wherein a length of the cable support member is a same as a width of the metal plate.

9. The cable clamp according to claim 1, wherein the cable support member is tapered from another end side of the cable support member to the end side of the cable support member in the insertion direction.

10. The cable clamp according to claim 1, wherein one side surface of the cable support member has a width equal to a distance between the at least two cables.

11. The cable clamp according to claim 1, wherein the insertion direction of the cable support member is between central axes of the at least two cables.

12. The cable clamp according to claim 1, wherein the cable support member is insertable between the at least two cables after arranging the at least two cables at fixed positions.

13. The cable clamp according to claim 1, further comprising:

a deformation preventing rib extending perpendicular to the mounting flange portion along the outer periphery of the three cables.

14. The cable clamp according to claim 13, wherein the deformation preventing rib extends from an edge of the mounting flange portion to a corner of the metal plate.

15. The cable clamp according to claim 1, wherein the cable support member is continuously tapered from another end side of the cable support member to the end side of the cable support member in the insertion direction.

16. The cable clamp according to claim 1, wherein the end side of the cable support member contacts the metal plate.

17. The cable clamp according to claim 1, wherein the mounting flange portion is arranged within a space formed between two parallel planes respectively extending in the insertion direction through each of the central axes of the two horizontally arranged cables.

18. The cable clamp according to claim 1, wherein the mounting flange portion protrudes outward from a vertex of a triangle formed by the three cables that are triangularly arranged.

19. The cable clamp according to claim 1, wherein the line that crosses with the line that connects the central axes of the two horizontally arranged cables extends in an overlapped area of the end portions of the metal plate.

20. The cable clamp according to claim 19, wherein the line that crosses with the line that connects the central axes of the two horizontally arranged cables passes through a center of one of the three cables.
