Abstract
The utility model provides a connecting clamp for connecting a ground wire, wherein the connecting clamp for connecting a ground wire is applicable to a power system. The connecting clamp for connecting a ground wire comprises a C-shaped ground wire connecting clamp. Ground wire connecting screws are arranged on the ground wire connecting clamp. The lower surface of the ground wire connecting clamp is fixedly connected with a vertically-arranged protective bushing. A lead screw is threaded and installed on the ground wire connecting clamp at the central position of the protective bushing through the matching of threads. The lower end of the lead screw is provided with a linear lead screw rotating handle, and the upper end of the lead screw is rotatably connected with an elongated pressing plate in a matching manner. One end of the pressing plate is placed in a rectangular sliding chute in the ground wire connecting clamp. Compared with existing fixed bar type ground wire connecting clamps, the connecting clamp of the utility model has advantages of small size, light weight, secure and reliable ground wire connection, simple structure, long service life, easy carry, easy storage, easy custody and flexible utilization, and the connecting clamp of the utility model is not easy to damage.
Description
Technical field
The utility model relates to the earth connection connection folder that a kind of suitable electric power system is used.
Background technology
Before the electric power apparatus examination operation begins, need to be on the electric equipment both sides wire after the power failure hanging earthing conductor, with protection service work personnel's safety.Hanging earthing conductor adopts the spring peaked hook with insulating bar at present, and this kind has bar spring peaked hook to have following shortcoming:
1, owing to the long insulation body of rod of traction, the body of rod swings with the wind behind the hanging earthing conductor, makes coupling hook unstable with being connected of wire, produces to become flexible, and easily causes coupling hook and poor wire connection;
2, press tongue spring mechanism complex structure, be subject to colliding with and easily damage, and press the active force of tongue spring to reduce gradually after repeatedly using, lose its due clamping force, useful life is low;
3, overall weight and volume are larger, are inconvenient to carry, use and deposit keeping.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of hanging earthing conductor safe and reliable, simple in structure, and is not fragile, and the earth connection that is convenient for carrying, uses and is connected keeping connects folder.
The technical scheme that realizes above-mentioned purpose is: a kind of earth connection connects folder, it has a c-shaped earth connection clamp, be provided with the ground wire connecting screw on this earth connection clamp, below this earth connection clamp, be fixedly connected with a perpendicular protecting pipe of putting, the center that is positioned at this protecting pipe is installed on the described earth connection clamp through threaded engagement a leading screw, the lower end of this leading screw is provided with the leading screw rotating handle that is in-line, rotatably the be connected pressing plate of a strip of the upper end of this leading screw, an end of this pressing plate place in the rectangle chute on the described earth connection clamp.
The technical solution of the utility model also comprises: described ground wire connecting screw vertical array arranges two.
When the utility model uses, utilize the ground wire connecting screw that earth connection is connected folder with this earth connection and finish connection, be grounded line in the upper end of insulating bar and connect being connected of folder and insulating bar by protecting pipe is nested with, and in-line notch and the cooperation realization insulating bar of in-line rotating handle and being connected of leading screw by being arranged on the insulating bar upper end.After in the power devices wire enters C shape earth connection clamp, drive leading screw and rotate by rotating insulating bar, make the pressing plate clamping wire that moves up, after earth connection connects the folder clamping wire, take off insulating bar, finish the hanging earthing conductor of maintenance electric equipment; After upkeep operation was finished, recycling insulating bar and the in-line notch of this insulating bar upper end and cooperating of in-line rotating handle unclamped wire, take off this earth connection and connect folder, finish the dismounting that earth connection connects folder.
The utility model is compared with existing fixedly rod-type earthing clamp, has following advantage:
1, volume is little, and is lightweight, and hanging earthing conductor is safe and reliable;
2, simple in structure, not fragile, long service life;
3, be convenient for carrying and deposit keeping, use flexibly.
Description of drawings
Fig. 1 is that this earth connection connects the clamping structure front view;
Fig. 2 is the right view of Fig. 1.
Embodiment
By reference to the accompanying drawings embodiment of the present utility model is described.
Such as accompanying drawing, this earth connection jockey has a c-shaped earth connection clamp 1, one side lower part of this earth connection clamp 1 is provided with vertically disposed two ground wire connecting screws 2, fixedly the circular jacket pipe 3 of putting is erected in welding one below earth connection clamp 1, the center that is positioned at this protecting pipe 3 is installed on through threaded engagement a perpendicular leading screw 4 of putting on the earth connection clamp 1, the lower end of this leading screw 4 is with the leading screw rotating handle 5 that is in-line, the plush copper shape is arranged in the upper end of this leading screw 4, its plush copper places in the plush copper caulking groove below the strip pressing plate 6, realize rotatably being connected of leading screw 4 and pressing plate 6, one end of this strip pressing plate 6 extend in the rectangle chute on the earth connection clamp 1, limits this pressing plate 6 and moves up and down in this chute.
