[0016] A rigid contact network anchor section joint busbar suspension clamp comprises a first suspension seat 3 and a second suspension seat 4 which are fixedly suspended side by side, wherein a first busbar clamp 1 and a second busbar clamp 2 are horizontally hinged side by side at the lower ends of the first suspension seat 3 and the second suspension seat 4, and the first busbar clamp 1 and the second busbar clamp 2 are electrically connected via a flexible conductor 5.

[0017] In one embodiment, the first busbar clamp 1 and the second busbar clamp 2 are both composed of an inverted "T"-shaped clamp body 7, a clamp plate 8 and a conductive plate 9; the upper end of the clamp body 7 has a double-ear structure, and the lower ends of the first suspension seat 3 and the second suspension seat 4 have a single-ear structure, and the double-ear structure and the single-ear structure are hinged through a horizontal hinge shaft 6; the conductive plate 9 is arranged between the clamp body 7 and the clamp plate 8, and the three are fixed together by a first bolt pair 10, and the clamp plate 8 is located below both sides of the clamp body 7 and protrudes from the outside of the conductive plate 9; the two ends of the flexible wire 5 are respectively fixedly connected to the protruding parts of the two conductive plates 9. In this embodiment, the flexible wires 5 are preferably two, and can also be increased or decreased according to the current carrying requirements of the line.

[0018] In one embodiment, the two ends of the flexible wire 5 are crimped with connecting terminals 11, and the connecting terminals 11 are fixed to the protrusions of the two conductive plates 9 through second bolt pairs 12, so that the flexible wire 5 is located on one side above the wire clamp body 7.
