Description

Technical Field

[0001] The utility model relates to the technical field of leaky cable clamps, in particular to a sideways hanging leaky cable clamp. Background Art

[0002] There are periodic slots distributed on the outer conductor of the leaky cable, and the electromagnetic wave signal radiates outward from the slots. In order to facilitate the identification of the radiation direction of the leaky cable, there are usually one or two raised identification ribs on the outside of the leaky cable. The identification ribs are located on the opposite side of the radiation direction of the leaky cable. In engineering applications, the leaky cable needs to be fixed with a leaky cable hanging fixture. The purpose of fixing with this hanging fixture is, firstly, to maintain the correspondence of the radiation direction of the leaky cable, and secondly, to maintain the fixed position of the leaky cable and avoid factors such as vibration from damaging the connection quality of the leaky cable. Existing leaky cable hanging fixtures, schematic diagram of which is shown in Figure 1 It is the corresponding hanging fixture of conventional cables. It does not fully consider the deviation of the installation direction and radiation angle of the leaky cable. The identification ribs of the leaky cable can only be arranged upward, which causes the electromagnetic wave signal radiated by the leaky cable to not be effectively utilized, thus affecting the coverage effect of the leaky cable wireless coverage link.

[0023] In a specific implementation, a side convex area 32 is provided on the right side of the radial area of ​​the annular area 31 , and the locking connection area 33 is arranged below the annular area 31 .

[0024] During specific implementation, it also includes an L-shaped support plate 50. The lower part of the second vertical connecting plate 23 is provided with an L-shaped support plate 50.

A second vertical plate 51 arranged downward is provided on the right side of the horizontal support plate 52. A group of positioning holes are provided on the second vertical plate 51. The lower area of ​​the second vertical connecting plate 23 is provided with two groups of vertically arranged waist-shaped holes at intervals in the height direction, which are the first waist-shaped holes 231 in the upper part and the second waist-shaped holes 232 in the lower part. The first waist-shaped holes 231 are used to be combined and matched with the corresponding connecting holes of the vertical plate 321 of the lateral convex area 32 and fixed by connecting bolts. The second waist-shaped holes 232 are used to be combined and matched with the positioning holes on the second vertical plate 51 and fixed by connecting bolts.
