Earth connection is the lifeline ensureing power construction personnel on site safety work.In recent years along with electrical network is defeated, join, the increasing of power transformation project construction and technological transformation dynamics, particularly the O&M maintenance of power network line equipment is increasing, when carrying out site examining and repairing operation, the technical measures ensureing safety must be taked, wherein one is exactly by installing earth connection, guarantees personal safety during maintainer's operation.Current use earth connection employing multiply high-quality annealed copper wire is stranded to be formed, cover softness, resistant to elevated temperatures transparent insulation sheath outward, can prevent the wearing and tearing to ground connection copper cash in using, the wire clamp of conductor wire end and earth terminal adopts copper tip die casting, and the securing member metal supporting with it is all through Nickel Plating Treatment.On construction operation site grounding wire uses, exhale high different owing to being subject to shaft tower, operating environment is different, equipment ground position is different, cause the earth connection of at present unified model can not be general, especially production maintenance unit is when tackling different maintenance location, due to the problem because of earth connection curtailment, causes the problem that cannot install particularly outstanding.
Summary of the invention:
For overcoming the defect of prior art, the object of the present invention is to provide a kind of earth connection connecting clip, earth connection length can be chosen according to on-the-spot actual needs and connecting, solve because installing problem that is high different, the equal operation field of phase spacing exhaled by shaft tower.
Technical solution problem of the present invention adopts following technical scheme:
Arrange in the hex nut of U-shaped, be fixedly connected with the first earth connection intubate at the blind end of described hex nut along the axis direction of nut; The screw rod mated with described hex nut is set, is fixedly connected with the second earth connection intubate in the rear end of described screw rod along the axis direction of screw rod, and on described screw rod, is fixed with the hold-down nut for increasing bolt rotary moment of torsion;
The caliber of described first earth connection intubate, the second earth connection intubate mates with the wire diameter of connecting wires, and is intervally distributed with on the tube wall of the first earth connection intubate, the second earth connection intubate and is easy to intubate of connecting wires to press from both sides flat through hole/counterbore.
Arrange four hex nuts in U-shaped, described in each, the blind end of hex nut is fixedly connected with the first earth connection intubate along the axis direction of nut; The caliber of described first earth connection intubate mates with the wire diameter of connecting wires, and described earth connection is plugged in described first earth connection intubate, and is intervally distributed with on the tube wall of the first earth connection intubate and is easy to intubate of connecting wires to press from both sides flat through hole/counterbore;
The conduction contiguous block of box-shaped is set, two opposing end surfaces of described contiguous block be provided with altogether four with described four hex nuts corresponding conductive lever connected one by one, the surface of described contiguous block is provided with insulating sheath.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, earth connection connecting clip of the present invention is easy for installation, flexible, reliably can be crimped with earth connection by hydraulic pressure, be connected firmly, two of contiguous block in opposite directions end face be provided with four screw rods, four earth connections can be connected by nut and earth connection intubate simultaneously.
2, after earth connection connecting clip of the present invention comes into operation, can according to field operation needs, free different earth connection length connects, and solves because installing problem that is high different, the equal operation field of phase spacing exhaled by shaft tower, meet different work task, the use of different work environment.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of a kind of earth connection connecting clip of the present invention; Fig. 2 is the structural representation of hex nut; Fig. 3 is the structural representation of the another kind of earth connection connecting clip of the present invention.
Number in the figure: 1 hex nut, 2 first earth connection intubate, 3 screw rods, 4 second earth connection intubate, 5 hold-down nuts, 6 earth connections, 7 through holes/counterbore, 8 contiguous blocks, 9 insulating sheath.
Below by way of embodiment, and the invention will be further described by reference to the accompanying drawings.
Embodiment:
Embodiment 1: composition graphs 1,2, the earth connection connecting clip of the present embodiment, it is characterized in that, hex nut 1 in U-shaped is set, from the axis direction of hex nut, one end open is closed in its one end, is fixedly connected with the first earth connection intubate 2 at the blind end of hex nut 1 along the axis direction of nut; The screw rod 3 mated with hex nut 1 is set, is fixedly connected with the second earth connection intubate 4 in the rear end of screw rod 3 along the axis direction of screw rod, and on screw rod 3, is fixed with the hold-down nut 5 for increasing bolt rotary moment of torsion;
In specifically arranging, the caliber of the first earth connection intubate 2, second earth connection intubate 4 with connect wires 6 wire diameter mate, earth connection is plugged in intubate, and is intervally distributed with on the tube wall of the first earth connection intubate 2, second earth connection intubate 4 and is easy to intubate of connecting wires to press from both sides flat through hole/counterbore 7.
