Abstract
The utility model discloses an electric measuring and distributing three-phase terminal box, comprising a box body and a box cover. The box body is internally provided with a copper row. The box body is also internally provided with an integrated medium clapboard. The copper row is arranged below the medium clapboard. The copper row is screwed with a terminal bolt and a connecting screw. The side of the copper row which is positioned at one side of the connecting screw is provided with a terminal hole. A terminal opening is arranged on the medium clapboard corresponding to the terminal bolt. A terminal cut is arranged on the side of the box body corresponding to the terminal bolt. A first round hole is arranged on the side of the box body corresponding to the terminal hole. The utility model is characterized in that the other side of the copper row is provided with two ground wire connecting holes; the other side of the box body is correspondingly provided with a second ground wire round hole; and a ground wire connecting screw is arranged on the copper row corresponding to the ground wire connecting hole. The utility model has the advantages of easily identifying the fire wire and the ground wire when in mounting, decreasing the dangerous factors for maintainer, and being beneficial for mounting, maintenance and management.
Description
[technical field]
The utility model relates to a kind of electric energy metrical and distributes terminal box.
[background technology]
Along with The development in society and economy and growth in the living standard, install in the residential building that Every household has an ammeter popularizes, receive each kilowatt-hour meter from the house lead in cable and be equipped with special-purpose terminal box, but at present used junction box structure is unreasonable, wiring is relatively more chaotic, be unfavorable for administering and maintaining, some resident family's self-control or the terminal box copper bar of applying mechanically expose, and wiring all is that compression joint type connects, and does not have the sealing insulation, both dangerous, also easily by stealing.In light of this situation, it is neat that just the someone has invented a kind of wiring, helps the terminal box of installation and maintenance and management.Look into Chinese patent, one Granted publication number is CN2600963Y, name is called the utility model patent that electric energy metrical distributes the three-phase terminal box, disclose following content: a kind of electric energy metrical distributes the three-phase terminal box, comprise box body, the box body inner copper line, it is characterized in that described copper bar has three, be I-shaped, be provided with integrally formed median septum in the box body, three copper bars are positioned under the median septum, be bolted with connection bolt and attachment screw on the copper bar, copper bar is provided with wiring hole in the side correspondence that is positioned at attachment screw one side, position corresponding to connection bolt on the median septum is provided with the wiring opening, and the side of box body is provided with the wiring breach corresponding to the position of connection bolt, and the side of box body is provided with the wiring circular hole corresponding to the position of wiring hole.This technical scheme has just solved the shortcoming of above-mentioned prior art, but, when the cable on the terminal box is received ammeter, all there are ground wire and live wire to insert, during the wiring hole outlet that is provided with on the copper bar of this terminal box, its ground wire and live wire all are mounted in the same side of box body, just there is unsafe factor in such mode of connection, in case the crust of electric wire is easy to cause the phenomenon of short circuit because other reasons is destroyed, simultaneously, not same operator, of long duration, when carrying out maintenance and management again, its ground wire and live wire just can not directly be distinguished with eyes and come, thereby just bring the hazards of electric shock to the attendant.
[utility model content]
In view of the problem that background technology exists, the technical problems to be solved in the utility model provides a kind of not only safety but also the electric energy metrical easily ground wire and live wire distinguished distributes the three-phase terminal box.
For solving the problems of the technologies described above, the utility model adopts following technical scheme to realize: a kind of electric energy metrical distributes the three-phase terminal box, comprise box body and lid, in box body, be provided with copper bar, be provided with body formed median septum in the box body, copper bar places the below of median septum, be bolted with connection bolt and attachment screw on the copper bar, copper bar is provided with wiring hole in the side correspondence that is positioned at attachment screw one side, position corresponding to connection bolt on the median septum is provided with the wiring opening, the side of box body is provided with the wiring breach corresponding to the position of connection bolt, the side of box body offers the first wiring circular hole corresponding to the position of wiring hole, it is characterized in that, is provided with two ground wires in the another side of copper bar and connects the hole, and at the second wiring circular hole of the another side of box body correspondence, meeting the place, hole corresponding to ground wire and be provided with the ground wire attachment screw at copper bar.
Above-mentioned electric energy metrical distributes in the three-phase terminal box, and described median septum is provided with parting bead, and connection bolt and attachment screw are separated.
The utility model is applicable to that the three-phase house lead in connects table, one road inlet wire, the multichannel outlet, it is neat to connect table, safe in utilization, when safeguarding, the attendant can distinguish live wire and ground wire at an easy rate, no longer test, with the naked eye just can distinguish, help installation, maintenance and management by surveying electric tool.
[description of drawings]
In conjunction with the accompanying drawings and embodiments the utility model is further described again below.
Fig. 1 is plan structure figure of the present utility model;
Fig. 2 is a construction profile of the present utility model;
Fig. 3 is an another side of the present utility model structure chart.
[embodiment]
As shown in the figure, this electric energy metrical distributes the three-phase terminal box, comprise box body 1 and lid 8, in box body 1, be provided with copper bar 4, be provided with integrated median septum 10 in the box body 1, copper bar 4 places the below of median septum 10, be bolted with connection bolt 7 and attachment screw 3 on the copper bar 4, copper bar 4 is provided with the wiring hole (not shown) in the side correspondence that is positioned at attachment screw 3-side, position corresponding to connection bolt 7 on the median septum 10 is provided with wiring opening (not marking among the figure), the side of box body 1 is provided with wiring breach 5 corresponding to the position of connection bolt 7, the side of box body 1 offers the first wiring circular hole 9 corresponding to the position of wiring hole, all live wires all are installed in this first wiring circular hole 9, after live wire passes the first wiring circular hole 9, with attachment screw 3 electric wire are fixed; Be provided with two ground wires in the another side of copper bar 4 and connect the hole (not shown), and at the second wiring circular hole 6 of the another side of box body 1 correspondence, meeting hole place corresponding to ground wire and be provided with ground wire attachment screw 2 at copper bar 4, thereby ground wire just passes the ground wire wiring hole that this second wiring circular hole 6 puts in copper bar 4, and property-line attachment screw 2 is fixing again.Described median septum 10 is provided with parting bead 11, and connection bolt 7 and attachment screw 3 are separated, like this, prevent because lid when leaking, and with live wire and earth short.Described lid 8 is the transparent body, helps being used for observation, safety utilization of electric power and anti-electricity-theft.
