Abstract
The invention relates to a novel grounding wire clamp for a ferromagnetic material grounding down lead. The novel grounding wire clamp comprises a clamp main body, a grounding copper block, a spring and powerful magnets. Each epitaxial plate of the clamp main body is embedded with one powerful magnet; the lower bottom surface of a top plate is connected with the grounding copper block through the spring; the grounding copper block is arranged between the two side plates; and one side wall of the grounding copper block is equipped with grounding terminals. The novel grounding wire clamp for the ferromagnetic material grounding down lead is scientific in design, reasonable in structure and convenient to use; the grounding wire clamp is suitable for the case that the grounding down lead is arranged along the wall (or a cement framework), can be directly absorbed on the ferromagnetic material grounding down lead without enabling the wire clamp to pass through the gap between the down lead and the wall (or the cement framework), is simple and convenient to wire, and prevents the wiring difficulty caused by the fact that a conventional wire clamp cannot pass through the gap between the down lead and the wall (or the cement framework); and through the utilization of the novel grounding wire clamp, work difficulty can be reduced, and work efficiency can be improved.
Description
Technical field
The present invention relates to the managing security tools and instruments in technical field of electric power, especially a kind of novel grounded wire clamp for ferromagnetic material down conductor.
Background technology
Down conductor in transformer station, usually arrange along wall (or cement framework), less with the distance of wall (or cement framework), conventional earthing clamp size is difficult to through the gap downlead and wall (or cement framework), cause certain difficulty to wiring, affect efficiency of construction.
Summary of the invention
The object of the invention is to make up the deficiencies in the prior art part, a kind of compact structure, easy to use is provided, the novel grounded wire clamp for ferromagnetic material down conductor of efficiency of construction can be improved.
The object of the invention is to be realized by following technological means:
A kind of novel grounded wire clamp for ferromagnetic material down conductor, it is characterized in that: comprise wire clip body, ground connection copper billet, spring and strong magnets, wire clip body comprises top board, left plate, right plate and extension plate, the left and right sides of top board bottom surface installs left plate and right plate respectively, the bottom of the outer wall of left plate and right plate installs the extension plate of a level respectively, equal setting-in strong magnets on each extension plate; The bottom surface of top board connects a ground connection copper billet by spring, and this ground connection copper billet, between two side plates, one of them sidewall of this ground connection copper billet installs earth terminal.
And described wire clip body adopts the metal of hard material or plastic materials to make.
And described strong magnets is inlaid in the lower surface of extension plate.
And described spring is under the state of naturally extending, and the lower surface of ground connection copper billet exceeds wire clip body lower surface.
Advantage of the present invention and good effect are:
1, the present invention utilizes magnet principle, devise a kind of earthing clamp be fixed on down conductor, this earthing clamp is made up of wire clip body, ground connection copper billet, spring and strong magnets, when wire clip body by utilizing powerful magnet for adsorption on the down conductor of ferromagnetic material time, ground connection copper billet is compressed by spring and down conductor surface, forms good electrical connection.Thus solve the difficulty that traditional wire clamp cannot cause to wiring through gap between downlead and wall (or cement framework), reduce work difficulty, accelerate operating rate, improve operating efficiency.
2, the present invention is reasonable in design, compact structure, cost are low, easy to carry, easy to use, is especially applicable to using when going out operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention (broken section);
Fig. 2 is overall structure schematic diagram of the present invention (omission binding post).
Embodiment
Embodiments of the invention are described in detail below in conjunction with accompanying drawing; It should be noted that, the present embodiment is narrative, is not determinate, can not limit protection scope of the present invention with this.
For a novel grounded wire clamp for ferromagnetic material down conductor, comprise wire clip body 9, ground connection copper billet 5, spring 3 and strong magnets 7, wire clip body adopts the metal of hard material or plastic materials to make, as the skeletal support of wire clamp entirety.Wire clip body comprises top board 2, left plate 1, right plate 4 and extension plate 8, the left and right sides of top board bottom surface installs left plate and right plate respectively, top board and two side plates form " several " character form structure, the bottom of the outer wall of left plate and right plate installs the extension plate of a level respectively, a bottom surface equal setting-in strong magnets (being equivalent to the lower surface being flush-mounted in wire clip body) of each extension plate, for being adsorbed in the down conductor of ferromagnetic material by wire clamp entirety.
The bottom surface of top board connects a ground connection copper billet by spring, this ground connection copper billet is between two side plates, as the electrical connection position of wire clamp and down conductor, copper billet should be different according to the demand of earth current, suitable size is set, guarantee the contact area with wire clamp, ensure that copper billet can move up and down at the groove position in wire clip body simultaneously, one of them sidewall of this ground connection copper billet is installed the earth terminal 6 that can be connected with practice ground line.
Spring is used for the fixing of ground connection copper billet and wire clip body, and when copper billet contacts with down conductor, provides enough contacts, and its length should meet under the state of elongation naturally, makes the lower surface of ground connection copper billet exceed wire clip body lower surface.
Operation principle of the present invention is:
During use, only need wire clamp be adsorbed on the down conductor of ferromagnetic material by strong magnet, now copper block surface should with down conductor close contact, and by spring compression, the earth connection needed for connecting from the ground lead of copper billet.
