Bottom can make pre-hinged strain clamp generate contact electric discharge to ground wire, bring great threat to route operation.Therefore zero electricity
The installation of bit line folder is it is prevented that pre-hinged strain clamp generates contact electric discharge to ground wire.
Utility model content
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a kind of zero potential wire clamp.
The purpose of this utility model is completed by following technical solution: a kind of zero potential wire clamp, under mainly including
Cover board, upper minor flaps and upper large cover are provided with the arc groove A and arc groove B interconnected, the song of arc groove A on lower cover plate
Rate radius is less than the radius of curvature of arc groove B, and upper minor flaps are equipped with arc groove C, and upper large cover is equipped with arc groove D, circular arc
Slot A and arc groove C form the in-profile for fitting closely ground wire, arc groove B and arc groove D-shaped at fitting closely preformed strain insulator
The in-profile of wire clamp；Upper minor flaps and upper large cover are mounted on lower cover plate by fastener, pre-hinged strain clamp and ground
The tie point of line is arranged in that there are the positions of certain distance with arc groove A and arc groove B tie point, so that a part peace of ground wire
There are exposed gaps in arc groove B and between ground wire and arc groove B.
At the position for the tie point that a side of the upper large cover is just pressed in pre-hinged strain clamp and ground wire, on
Minor flaps are pressed on ground wire, so that a part of ground wire for being mounted on arc groove B is exposed outside.
The fastener mainly includes screw bolt and nut, and spring washer and plain cushion are provided between nut and lower cover plate.
Lower cover plate, upper minor flaps and the upper large cover is cast by AL99.5 fine aluminium.
Bolt, nut, spring washer and the plain cushion uses stainless steel material.
The utility model has the following beneficial effects: the utility model acts on the crossover position of pre-hinged strain clamp and ground wire
On, it can prevent pre-hinged strain clamp from generating contact electric discharge to ground wire, elimination contact, which discharges, runs bring to route
Security risk, it is ensured that route operational safety；It is fastened, is installed simple and convenient using general bolt.

Specific embodiment
Detailed introduction is done to the utility model below in conjunction with attached drawing:
As shown in the picture, a kind of zero potential wire clamp mainly includes lower cover plate 1, upper minor flaps 2 and upper large cover 3, lower cover plate
The arc groove A9 and arc groove B10 interconnected is provided on 1, the radius of curvature of arc groove A9 is less than the curvature of arc groove B10
Radius, upper minor flaps 2 are equipped with arc groove C12, and upper large cover 3 is equipped with arc groove D13, arc groove A9 and arc groove C12 shape
At the in-profile for fitting closely ground wire 8 (steel strand wires), arc groove B10 and arc groove D13 formation fit closely preformed strain insulator
The in-profile of wire clamp 11；Upper minor flaps 2 and upper large cover 3 are mounted on lower cover plate 1 by fastener, clamp preformed strain insulator
Wire clamp 11 and ground wire 8 prevent that contact discharges.The fastener mainly includes bolt 4 and nut 5, nut 5 and lower cover
Spring washer 6 and plain cushion 7 are provided between plate 1 to increase clip stability, bolt 4, nut 5, spring washer 6 and plain cushion 7 use stainless steel
Material, and be all M12, it can install more conveniently, reduce installation difficulty, accelerate the speed of installation, and be not easy to give birth to
Rust, long service life.The setting of the tie point of pre-hinged strain clamp 11 and ground wire 8 is connect with arc groove A9 and arc groove B10
Point there are the position of certain distance (3-10mm) so that a part of ground wire 8 is mounted in arc groove B10 and ground wire and circular arc
There are exposed gap between slot B10, it is effectively prevented pre-hinged strain clamp 11 and ground wire 8 generates contact electric discharge.
Lower cover plate 1, upper minor flaps 2 and the upper large cover 3 is cast by AL99.5 fine aluminium, is connected improving
Property, prevent from can also preventing pre-hinged strain clamp 11 and ground wire 8 from generating contact electric discharge while the increase of resistance value.
Optimal embodiment: a side of the upper large cover 3 is just pressed in pre-hinged strain clamp 11 and ground wire 8
Tie point position at, upper minor flaps 2 are pressed on ground wire 8 so that a part of ground wire 8 for being mounted on arc groove B10 it is exposed
Outside.
The utility model use process: lower cover plate 1 is bonded pre-hinged strain clamp 11 (shield lines) and ground by the first step
Line 8 (steel strand wires), shield lines end and left hole circle center distance size should be less than the half equal to upper 3 width of large cover；Second
Upper large cover 3 is bonded shield lines by step, and shield lines end should not exceed the coverage area of large cover 3；Third step, will be upper small
