Detailed ways

As shown in Figure 1, Figure 2 and Figure 3, a cable support suitable for large-pitch installation includes a cable support column 10, a cable support arm 12 and a cable clamp 11, and the inner side of the cable support column 10 is Two or more cable support arms 12 are connected, and one or more cable pallet clamps 11 are respectively arranged on the cable support arms 12;

The cable holder clamp 11 includes a cable rigid fixing clip body 1, a cable holder 3 and a threaded connection assembly, and the cable rigid fixing clip body 1 is detachably mounted on the cable holder 3 through a threaded connection assembly, The length of the cable supporting plate 3 is 200mm, and there are two symmetrical arc grooves on the described cable supporting plate 3, and a square neck bolt hole 4 is provided in the center of the cable supporting plate 3, The top of the cable rigid fixing clip body 1 is arc-shaped, and the radian of the top of the cable rigid fixing clip body 1 matches the curvature of the arc groove, and the inner side of the cable rigid fixing clip body 1 is also installed with a rubber An insulating pad 2, the two side walls of the cable rigidly fixing the clip body 1 form an included angle of 60°.

The utility model can fix and install multiple cables at one time. When the cables need to be fixed by using the cable clamp 11, the cable support plate 3 is fixedly connected to the cable support arm by passing the external bolt 9 through the square neck bolt hole 4 first. Then loosen the threaded connection assembly and place the two cables in the arc groove on the cable support plate 3, then superimpose the third cable on the top between the cables in the two arc grooves, and finally pass Tighten the threaded connection assembly and use the cable rigid clamp body 1 and the cable support plate 3 to clamp and fix the three cables; the inner side of the cable rigid clamp body 1 is also equipped with a rubber insulating pad 2, which is used for protection.

Both the cable rigid fixing clip body 1 and the cable support plate 3 in this design are made of non-magnetic material aluminum. If the cable rigid fixing clip body 1 and the cable supporting plate 3 are made of iron or other magnetic materials, eddy currents will be generated; the cable rigid fixing clip body 1 and the cable supporting plate 3 in this design are made of non-magnetic material aluminum to avoid eddy currents generation.

The threaded connection assembly shown in Figure 2, Figure 4 and Figure 5 includes bolts 5 and nuts 6, the two ends of the cable rigid fixing clamp body 1 are respectively connected with a first connecting lug 8, and the cable supporting plate The two sides of 3 are respectively connected with a second connecting lug 7, and the corresponding positions of the first connecting lug 8 and the second connecting lug 7 are each provided with a through hole, and the bolts 5 are passed through in turn. Connect with the nut 6 through the through holes on the second connecting lug 7 and the first connecting lug 8 . When the threaded connection assembly needs to be loosened, the nut 6 can be rotated to allow relative movement between the first connection ear seat 8 and the second connection ear seat 7; The nut 6 clamps and fixes the first connecting lug 8 and the second connecting lug 7 , so that there is no relative movement between the first connecting lug 8 and the second connecting lug 7 .
