Detailed description of the invention

For making the purpose of this utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.

Embodiment:

Communications cable grounding connection protection device, this device includes upper shield 1, lower shield 2, inner cover 3, screw 4, nut 5, tapping screw 6; Upper shield 1 for upper half round platform 101 with upper half cylinder 102 in conjunction with shape, the upper half cylinder 102 both sides sidewall of upper shield 1 is respectively arranged with a up knob 7, and up knob 7 centre has the first hole 701, and upper half round platform 101 upper bottom surface has the second hole 103; Lower shield 2 for lower half round platform 201 with lower half cylinder 202 in conjunction with shape, the lower half cylinder 202 both sides sidewall of lower shield 2 is respectively arranged with a lower handle 8, and lower handle 8 centre has the 3rd hole 801, and lower half round platform 201 upper bottom surface has the 4th hole 203; Upper shield 1 is the same with lower shield 2 shape size, upper shield 1 and lower shield 2 coalition be round platform with cylinder in conjunction with shape, this coalition is hollow form; Screw 4 is by the first hole 701 and the 3rd hole 801 and nut 5 combined fixed; Inner cover 3 is hollow form, and the outer face of inner cover 3 has the 5th hole 301 up and down, and two the 5th hole 301 positions are corresponding with the second hole 103 and the 4th hole 203 respectively; Tapping screw 6 is fixed with upper shield 1 by the 5th hole 301 and the second hole 103, and tapping screw 6 is fixed with lower shield 2 by the 5th hole 301 and the 4th hole 203.

Implement step:

A. being placed on below corrugated tube 9 by lower shield 2, be placed on by upper shield 1 above corrugated tube 9, upper shield 1 is corresponding with lower shield 2 position;
