Abstract
The present invention relates to a kind of earth-continuity testing tool, it is characterized in：Including the connecting pole being made up of one section of cylinder (2) and one section of cone (1), cylinder (2) one end of the connecting pole is fixedly connected by connecting seat (4) with insulating bar (5), and the cut of file or topping are provided with the surface of its cone (1) one end, it is additionally provided with least one binding post (3) on the surface of cylinder (2) one end in addition.Test proves that, using instrument of the invention after, can rapidly polish and connecting test instrument, it is ensured that the safety of work.Simultaneously as the buffed surface to being grounded band iron is substantially reduced, both can effectively prevent exposed ground connection band iron from phenomenon of rupture occurred by corrosion, its attractive in appearance and life-span will not have been influenceed again.And monospace earth-continuity test average time was shortened to about 2.75 minutes by original about 6 minutes, so as to largely improve the efficiency that grounded screen connects test job.
Description
Technical field
The present invention relates to a kind of earth-continuity testing tool.
Background technology
The metal shell of electrical equipment must effective grounding, this be ensure personal safety, the important measures of equipment safety.Connect
The formal ground connection band iron to equipment of ground continuity test work whether the inspection carried out with grounded screen good connection, can find in time
Potential safety hazard, it is ensured that the safe and stable operation of power network.
But found by long-term use, existing test clamp is difficult to realize good connection with ground connection band iron that its is main
Reason is that ground connection band iron scribbles antirust paint or corrosion is serious, although by polishing, contact surface can make moderate progress, but so can be notable
Lengthen working hours and extensive damage antirust paint necessarily causes the corrosion for being grounded band iron to aggravate.
The content of the invention
It is an object of the invention to provide a kind of simple structure, earth-continuity testing tool easy to use, can be conveniently high
Realize that good conductive is connected with ground connection band iron with test in effect ground.
A kind of earth-continuity testing tool, it is particular in that：Including being made up of one section of cylinder and one section of cone
Connecting pole, the cylindrical member at one end of the connecting pole is fixedly connected by connecting seat with insulating bar, and in the table of its cone one end
Face is provided with the cut of file or topping, is additionally provided with least one binding post on the surface of the cylindrical member at one end in addition.
Wherein connecting seat is circular tube shaped, and the two ends of the connecting seat are set on connecting pole and insulating bar and are spiral shell
Line is connected.
Two planes are wherein provided with the surface of the cylindrical member at one end of connecting pole, each one is provided with two planes
Individual screwed hole, detachably binding post is provided with screwed hole.
Wherein connecting pole and binding post use steel or copper material.
Test proves that, using instrument of the invention after, can rapidly polish and connecting test instrument, it is ensured that work
The safety of work.Simultaneously as the buffed surface to being grounded band iron is substantially reduced, exposed ground connection band iron both can have effectively been prevented to be subject to
There is phenomenon of rupture in corrosion, and its attractive in appearance and life-span will not be influenceed again.And monospace earth-continuity is tested into average time by original
That comes has shortened to about 2.75 minutes for about 6 minutes, so as to largely improve the efficiency that grounded screen connects test job.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the present invention.
Specific embodiment
As shown in figure 1, the present invention is a kind of earth-continuity testing tool, including by one section of cylinder 2 and one section of cone 1
The connecting pole of composition, one end of cylinder 2 of the connecting pole is fixedly connected by connecting seat 4 with insulating bar 5, and in its cone 1
The surface of one end is provided with the cut of file or topping, is additionally provided with least one binding post 3 on the surface of the one end of cylinder 2 in addition.
Two planes specifically are provided with two relative surfaces of one end of cylinder 2 of connecting pole, are each opened in two planes
There is a screwed hole, binding post 3 detachably is installed in screwed hole.
Specifically connecting seat 4 be circular tube shaped, the two ends of the connecting seat 4 be set on connecting pole and insulating bar 5 and
It is threaded connection.Above-mentioned connecting pole and binding post 3 use steel or copper material.
Application method of the invention is：
Insulating bar 5 is held when using, the tip of cone 1 of connecting pole of the present invention is connect with part exposed on ground connection band iron
Touch, you can connecting test line is tested on binding post 3.If there is no exposed part or exposed part to become rusty on ground connection band iron
Erosion, then can obtain the naked of one piece of very little by the cut of file on the surface of cone 1 or the corner part of topping friction grounding band iron
Show up product, then withstood with the tip of cone 1 of connecting pole ensure good contact by tested, it is to avoid on the ground connection band iron
Fall the rust preventive coating of large area with dwarf's filing.
