Abstract
The utility model relates to an electric energy measurement equipment, in particular to a theft-proof end cover for an induction-type single-phase KWH meter, which comprise an end cover plate with a connecting section corresponding to the connecting section of a junction box arranged on and is characterized in that a sheltering part for the outlet terminal extends downwards from one side approaching the outlet terminal of the junction box on the end cover plate. A sheltering cover is arranged on one side approaching the locking part of the upper shell and the lower shell on the end cover plate. The theft-proof end cover for an induction-type single-phase KWH meter mainly solves the problems that the flat-end end cover of the prior single-phase KWH meter can protect the electrical components inside the junction box and yet fails to prevent thieves from conducting electricity thefts in the way of changing the connection mode of the outlet terminal of the junction box or destroying the locking device, and simultaneously strengthens the safe-guarding distance of the KWH meter with the outside world.
Description
Technical field
The utility model relates to a kind of electric energy measuring equipment, particularly the anti-electricity-theft end cap of induction type single-phase watt-hour meter.
Background technology
Along with the high speed development of Chinese national economy, living standards of the people improve constantly, and the kind and the quantity of household electrical appliance increase sharply in ordinary family, and home-use electric weight grows with each passing day." covil construction electrical design standard " and power supply department clearly stipulate, no matter be high level or multi-storey building, should adopt all that Every household has an ammeter, and it is complete separately to carry out electricity consumption metering and protection.The power supply house lead in device of China residential houses was quite simple and crude in the past, fixed a single-phase watt-hour meter on a plank, and one plug-in strip and two ceramic pluging type fusing, do not have protected enclosure.Therefore, be easy to generate two subject matters after the installation:
1, some electrical equipments in this equipment (as: ceramic pluging type fusing) are very easily stolen by the people, damage.
2, the simple syndeton of this single-phase watt-hour meter is as easy as rolling off a log is the electricity filching person utilization, causes stealing electricity phenomenon.
As shown in Figure 1, existing single-phase watt-hour meter table body comprises upper casing A, lower casing B and terminal box C, can connect by catch member D between this upper casing A and the lower casing B, this terminal box C is positioned at the side of lower casing B, is mainly used in to place electrical equipment E and wiring F is drawn from the one side; As shown in the figure: this terminal box C can be an one with lower casing B also, and at this moment, catch member D connects as one upper casing A, lower casing B and terminal box C in fact.In addition, for the electrical equipment E in the butted line box C protects, this terminal box C is provided with a plate end cap G, and this end cap G can be fixed on the open side of terminal box C by retaining element, so just can protect by the interior electrical equipment E of butted line box C.
Though the plate end cap that said structure is furnished with can be protected the electrical equipment in the terminal box, but can't prevent the mode of connection or the mode of the destruction catch member situation of carrying out stealing of electricity filching person by changing the terminal box leading-out terminal.
The utility model content
The purpose of this utility model is to provide a kind of induction type single-phase watt-hour meter anti-electricity-theft end cap; can protect the interior electrical equipment of terminal box though mainly solve the plate end cap of existing single-phase watt-hour meter; but but can't prevent the mode of connection or the mode of the destroying catch member situation of carrying out stealing of electricity filching person by changing the terminal box leading-out terminal, strengthen watt-hour meter and extraneous security protection distance simultaneously.
For addressing the above problem, the utility model is achieved in that
The anti-electricity-theft end cap of a kind of induction type single-phase watt-hour meter, it comprises an end casing, this end casing is provided with the connecting portion corresponding with the connecting portion of terminal box, it is characterized in that: this end casing is extended with the leading-out terminal occlusion part near under leading-out terminal one side direction of terminal box.
The anti-electricity-theft end cap of described induction type single-phase watt-hour meter is characterized in that: this end casing is provided with a covering near latch part one side of upper casing and lower casing.
By technique scheme, the beneficial effects of the utility model are:
The utility model has effectively prevented the mode of connection or the mode of the destroying catch member situation of carrying out stealing of electricity filching person by changing the terminal box leading-out terminal, has strengthened watt-hour meter and extraneous security protection distance simultaneously.

Fig. 1 is the structural representation of existing single-phase watt-hour meter.
Fig. 2 is the structural representation of single-phase watt-hour meter in the utility model.
Fig. 3 is the structural representation of the anti-electricity-theft end cap of the utility model induction type single-phase watt-hour meter.
Embodiment
See also Fig. 2,3, the utility model provides a kind of induction type single-phase watt-hour meter anti-electricity-theft end cap, and it is applied on as shown in Figure 2 the single-phase watt-hour meter table body.This table body comprises upper casing 1, lower casing 2 and terminal box 3, can connect by catch member 4 between this upper casing 1 and the lower casing 2, and this terminal box 3 is positioned at a side of lower casing 2, is mainly used in to place electrical equipment 5 and wiring 6 is drawn from the one side; As shown in the figure: this terminal box 3 is an one with lower casing 2, and at this moment, catch member 4 connects as one upper casing 1, lower casing 2 and terminal box 3 in fact.
As Fig. 3, this end cap 7 comprises an end casing 71, this end casing 71 is provided with the connecting portion 72 corresponding with the connecting portion 31 of terminal box 3, and this end casing 71 is extended with leading-out terminal occlusion part 73 near under leading-out terminal 32 1 side direction of terminal box 3, so just can take precautions against the stealing mode of change external terminal.
Moreover this end casing 71 is provided with a covering 74 near latch part one side of upper casing 1 and lower casing 2, can take precautions against the stealing mode of opening the table lid like this.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
