Abstract
The utility model relates to an electrical energy metering junction box comprising a connection box body and a face cover. The connection box body is a three-phase four-wire type or a three-phase three-wire type, and an electric voltage connection terminal and a current connection terminal are arranged on the connection box body. A special checking hole is beaten on the electric voltage connection terminal. When checking, a special secondary conductor wire can be inserted for convenience, safety, and shortcut. The connection box body cancels a group of current connection terminal, which can not cause connection adjustment when checking on site. The special checking hole is also beaten on the current terminal, the checking hole is directly inserted when checking, a connecting plate is opened, and series current is in a return circuit. The face plate of the connection box increases the link stoppers of the electric voltage and the current connecting plates. When working in the normal times, the current and the electric voltage connecting plates are in the correct position, and the face plate can be covered. When the current and the electric voltage connecting plates are not in the correct position, the face plate can not be covered. An arched notch which is corresponding to and tightly connected with the secondary conductor wire is arranged on the positive lateral face, so that the person for stealing electricity can not use a U-shaped ring for stealing.
Description
Technical field
The utility model relates to a kind of circuit connection device, particularly a kind of electric energy metrical terminal box.
Background technology
There is following shortcoming in the electric energy metrical terminal box of using in real work now: during (1) field-checking electric energy meter, voltage adopts clip to obtain, and easily comes off, and current return is connected, because many user's batch meters storehouse is little, and the wiring inconvenience.(2) when the work carelessness, very easily cause the voltage yoke plate not connect, electric current yoke plate short circuit or open circuit cause Lou metering.(3) when the initial loading table, current return only by two groups of electric current normal open terminals, must be adjusted wiring during field-checking, must cause metering inaccurate.(4) electricity filching person can use the stealing of " U " shape ring.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of electric energy metrical terminal box that makes things convenient for electrical energy meter calibration.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of electric energy metrical terminal box, it comprises junction box body and cover, junction box body is provided with voltage terminal block and electric current terminal block, be characterized in: described voltage terminal block is provided with upper connecting terminal and lower connecting terminal, connect by the voltage yoke plate between the upper and lower connection terminal, have the voltage check hole that communicates with connection terminal on the voltage terminal block; Described electric current terminal block is provided with one road normal open connection terminal and one tunnel folding connection terminal, the upper and lower connection terminal of folding connection terminal connects by the electric current yoke plate, has two electric current verification holes that communicate respectively with the upper and lower connection terminal of folding connection terminal on the electric current terminal block.
The technical problems to be solved in the utility model can also come by the following technical programs further to realize that described junction box body adopts three-phase and four-line formula or phase three-wire three formula.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, on described cover, be provided with voltage block and electric current block with voltage yoke plate, the corresponding position of electric current yoke plate, the electric current block also is provided with the rib of a retaining at electric current yoke plate sidepiece, and the front of cover also is provided with the sign of " normal operation " and " out of service ".When normal operation, cover covers on junction box body, and voltage block and electric current block retaining are below corresponding yoke plate, and cover shows " normal operation " sign.When stoichiometric point was cancelled, electric energy meter was out of service, and at this moment, the voltage yoke plate disconnects, and the electric current yoke plate turn 90 degrees with the normal open terminal and is connected, and when covering cover again, because the effect of block is arranged, can't cover cover, then needed and will can cover after the cover turnback.Show the sign of " out of service " this moment on the cover.
The technical problems to be solved in the utility model can also come by the following technical programs to realize that further the edge interface place that cover cooperates with junction box body is provided with involutory arch notch respectively that the arch notch is located at the entrance hole below of junction box body.After the arch notch was involutory, relative closely contact with the secondary lead made electricity filching person can't use " U " shape ring to carry out stealing.
The utility model compared with prior art, (1) stamps special-purpose verification holes on the voltage splicing ear, during verification, special-purpose secondary lead is inserted, convenient, safety, quick.(2) junction box body is cancelled one group of current terminal, adjusts wiring in the time of can not causing field-checking.Also stamp special-purpose verification holes on the current terminal, directly insert during verification, open yoke plate, the series current loop.(3) increase the link stopper of voltage, electric current yoke plate on terminal block panel, when operate as normal, electric current, voltage yoke plate should be in the trams, and panel can cover.When electric current, voltage yoke plate during not in the tram, panel can't cover.(4) open the arch notch in the positive side of panel, relative closely contact with the secondary lead makes electricity filching person can't use " U " shape ring to carry out stealing.
