Description
Technical field
The utility model relates to a kind of earthing device of low-tension distribution box, specifically a kind of low-tension distribution box earth connection.
Background technology
Current low-voltage grounding wire is single tongue formula or double tongue type earth connection mainly, hold adjustable (busbar) earth connection, this type of earth connection is normally using needs to meeting during aerial condutor ground connection, but at interior distribution cabinet, particularly after upgrade of rural power grids on a large amount of outdoor distributing box used during ground connection because contact head is generally excessive, and outlet copper bar spacing is less than normal in distribution box, existing various earth connection cannot be installed, cause the no ground line protection of a large amount of low pressure power cut construction, violate core " hanging earthing conductor " work of " safety " technical measures; Owing to there is no the suitable small and exquisite earth connection for mounting ground in distribution box in prior art, cannot hang earth connection, for scheming conveniently, a lot of workmen replaces earth connection with safety wire, be clipped on outlet copper bar with crocodile clip safety wire and replace earth connection, alleviate no ground lineman and make hidden danger.As can be seen here, adopt existing no ground lineman's work and underproof substitute ground connection all can not ensure the safety of workmen, the personnel that very easily cause get an electric shock and die, and suffer heavy losses; " safety " (2013.11 editions) 6.5.3 clear stipulaties simultaneously: forbid replacing earth connection to use with individual safety wire, therefore, it is unallowed that individual safety wire is used for low-tension distribution box ground connection.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of low-tension distribution box earth connection that can ensure workmen's safety.
In order to solve the problems of the technologies described above, low-tension distribution box earth connection of the present utility model, comprise wire clip body, wire clip body forms a quiet chuck, wire clip body also having one can the dynamic chuck that moves up and down of relatively quiet chuck, clamping face is formed between quiet chuck and dynamic chuck inner side end, the lower end of dynamic chuck is fixedly connected with insulated tension pole through after the through hole of wire clip body, the bottom of insulated tension pole is connected with handle, insulated tension pole overcoat has the insulating coating be fixedly connected with wire clip body, spring is mounted with between insulating coating and insulated tension pole, the lower surface of dynamic chuck 2 is provided with the confined planes for limit spring, limited step is provided with in the first half endoporus of insulating coating, the top of spring is pressed on the confined planes of dynamic chuck, the lower surface of spring is pressed on the limited step of insulated tension pole, the upper end of insulating coating is also overlapped one section of insulating sleeve be fixedly connected with wire clip body.
Described insulated tension pole is insulating epoxy pull bar.
Described insulating sleeve is bellows.
Also be provided with the guide groove vertical with clamping face in described wire clip body, the side of dynamic chuck extend in guide groove and also can move up and down under guide groove guide effect.
The inner face of described quiet chuck is also provided with arcwall face.
After adopting above-mentioned structure, because insulated tension pole overcoat has the insulating coating be fixedly connected with wire clip body, spring is mounted with between insulating coating and insulated tension pole, in use procedure, to leave behind insulated tension pole, distance between quiet chuck and dynamic chuck separately, conductor is cut thus between quiet chuck and dynamic chuck, after unclamping hand, spring reset makes quiet chuck and dynamic chuck clamping conductor, its structure is simple, small and exquisite easy to use, ensure that the safety of workmen completely, the insulating sleeve simultaneously arranged can increase creepage distance, shorten the length of whole device, fail safe is high and be easy to carry, the guide groove arranged in wire clip body, fine guide effect is served in use procedure, the arcwall face that quiet chuck is arranged, increase the contact area of conductor.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model low-tension distribution box earth connection;
Fig. 2 is the partial structurtes schematic diagram of the utility model low-tension distribution box earth connection.
Embodiment
Below in conjunction with the drawings and specific embodiments, low-tension distribution box earth connection of the present utility model is described in further detail.
As shown in the figure, what low-tension distribution box earth connection of the present utility model will solve is exactly the requirement that other earth connection can not carry out proper grounding in low-tension distribution box, it comprises wire clip body 1, wire clip body forms a quiet chuck 2, the inner face of quiet chuck 2 is also provided with arcwall face 10, increase contact area when copper when can be used for non-distribution box, aluminum conductor ground connection, form is multiplex, wire clip body 1 also having one can the dynamic chuck 3 that moves up and down of relatively quiet chuck, clamping face is formed between quiet chuck 2 and dynamic chuck 3 inner side end, the lower end of dynamic chuck 2 is fixedly connected with insulated tension pole 4 through after the through hole of wire clip body, the bottom of insulated tension pole 4 is connected with handle 7, insulated tension pole 4 overcoat has the insulating coating 5 be fixedly connected with wire clip body 1, spring 6 is mounted with between insulating coating 5 and insulated tension pole 4, the lower surface of dynamic chuck 2 is provided with the confined planes for limit spring, limited step is provided with in the first half endoporus of insulating coating 5, the top of spring 6 is pressed on the confined planes of dynamic chuck 3, the lower surface of spring 6 is pressed on the limited step of insulated tension pole 4, the upper end of insulating coating 5 is also overlapped one section of insulating sleeve 8 be fixedly connected with wire clip body 1, wherein, said insulated tension pole 4 is insulating epoxy pull bar, said insulating sleeve 8 is bellows (sheath fan skirt), increases climbing arc distance, and shorten handle length, overall dimensions reduces, and is easy to carry, and workmen is happy to use.
Further can also be provided with the guide groove 9 vertical with clamping face in wire clip body 1, the side of dynamic chuck 3 extend in guide groove 9 and also can move up and down under guide groove 9 guide effect, can not increase contact head size thus and play firm effect.
