Description

Plug-in box for replacing single-phase electric energy meter without power outage

[ technical field ] A method for producing a semiconductor device

The utility model relates to a plug box specifically indicates a plug box that single-phase electric energy meter was used is changed in not having a power failure.

[ background of the invention ]

The single-phase electric energy meter is usually assembled with the plug box in a matching way, so as to adapt to the need of replacing the electric energy meter by live disassembly and assembly, the terminal in the plug box is provided with a corresponding short circuit hole, before the electric energy meter is replaced without power outage, the short circuit wire is inserted into the short circuit hole in advance, the operation of replacing the electric energy meter by disassembly and assembly can be carried out, however, the single-phase electric energy meter is in the daily operation process, the short circuit hole is exposed in the air, the short circuit hole is easy to cause dust and moisture in the air to corrode the short circuit hole, and therefore the short circuit hole is easy to oxidize and corrode.

In view of the above, there is a need for an improved docking pod.

[ Utility model ] content

Not enough to above-mentioned prior art exists, the utility model aims to provide a do not have a power failure and change peg graft box that single-phase electric energy meter was used, this peg graft box's short circuit hole is difficult for by oxidation, corruption, therefore the durability is good.

To this end, the utility model provides the following solution:

a plug-in box for replacing a single-phase electric energy meter without power outage comprises a box cover, a box base and four binding posts, wherein four through holes for the binding posts to be plugged in are formed in the side face of the box base at intervals; four terminals are located the tip of box seat inner place section and have been opened respectively into wire hole, just terminal and box seat fixed connection respectively, and four terminals stretch out the box seat respectively outside and form the end post separately, and its improvement point lies in: the top surfaces of the sections of the four binding posts in the box base are respectively provided with a short connecting hole, and the short connecting holes in the binding posts are not communicated with the wire inlet and outlet holes; the box cover is provided with four protective plugs at intervals on the inner bottom wall, the box cover is positioned on the box base, and the four protective plugs are inserted into the corresponding short-circuit holes one by one.

The utility model discloses still include two shorting stub, the lid is taken off from the box seat, and the shorting stub hole of adjacent terminal is connected through a shorting stub.

The utility model discloses increase after the configuration shorting stub, can swiftly carry out electrified meter change and need not change the electric energy meter again after having a power failure.

The two plugs of each short-circuit wire are respectively provided with a closed hole and an elastic body arranged in the closed hole.

After the elastic body is added, the contact internal resistance can be reduced, the repeated plugging resistance of each short-circuit plug is improved, and the closed hole of the plug cannot be reduced.

The communication seat, contact pin and the communication line of connecting the two are still installed respectively to the inner diapire of lid, so when being connected to single-phase electric energy meter with the contact pin, do benefit to external terminal and read the data of single-phase electric energy meter.

After the technical scheme is adopted, the utility model has the advantages of as follows and beneficial effect:

because the utility model discloses a lid is add after the protection stopper post, can effectively reduce the short circuit hole of each terminal and the contact of dust in the air, aqueous vapor to reduce the chance that the short circuit hole is by oxidation, corruption.
