Embodiment Construction

[0018] Such as Figure 1 to Figure 3 As shown, a leaky cable fireproof snap ring for high-speed railways of the present invention includes a lower cover plate 10 , an upper cover plate 20 , a bolt 31 , a spring washer 32 and a screw joint 40 . Both the lower cover 10 and the upper cover 20 are U-shaped parts, one end of the lower cover 10 and the upper cover 20 is rotationally connected by the screw 40, and the other end is detachable by bolts and nuts The connection constitutes an integrated structure of overturn connection, which can securely fix the leaky cable between the lower cover 10 and the upper cover 20, and the installation and fixing operation is convenient.

[0019] Specifically, the lower cover 10 has a screw connection end 11 of the lower cover, a connection end 12 of the lower cover and a bottom end 13 of the lower cover. The lower cover plate screwing end 11 and the lower cover plate connection end 12 are respectively located at two ends of the U-shape of the...

Abstract

The invention discloses a leaky coaxial cable fireproofing snap ring for a high-speed railway. The snap ring comprises a lower cover plate, an upper cover plate and a bolt, the lower cover plate and the upper cover plate are both U-shaped parts, one end of the lower cover plate is rotatably connected with one end of the upper cover plate, the other end of the lower cover plate is fixedly connectedwith a nut, and the other end of the lower cover plate is detachably connected with the end part of the upper cover plate through the bolt and the nut. The leaky coaxial cable fireproofing snap ringfor the high-speed railway is of an integrated structure, and has the advantages of firm structure, non-disengagement of parts, good safety, and fastness and convenience in mounting.

Description

technical field [0001] The invention relates to the related technical field of cable fixing equipment, and more precisely relates to a leaky cable fireproof snap ring for high-speed railways. Background technique [0002] Leaky coaxial cables, usually referred to simply as leaky cables or leaky cables or leaky cables, have basically the same structure as ordinary coaxial cables, consisting of three parts: an inner conductor, an insulating medium, and an outer conductor with periodic slots. While the electromagnetic wave is transmitted longitudinally in the leaky cable, the electromagnetic wave is radiated to the outside through the slot; the external electromagnetic field can also be induced into the inside of the leaky cable through the slot and transmitted to the receiving end. At present, the frequency band of the leaky coaxial cable covers more than 450MHz-2GHz, which is suitable for various existing wireless communication systems. The application occasions include subwa...
