Description
Affiliated technical field
The utility model relates to a kind of electric energy meter, the electric energy meter that especially a kind of terminal cap can be overturn.
Background technology
At present, the terminal cap of electric energy meter all is by the lead sealing screw retention, the First Astronautic Research Institute for Measurement and Test of power supply administration must turn on the lead sealing screw when calibration, just can carry out after taking down terminal cap, after the school is intact, must refill terminal cap, calibration like this, not only efficient is low, and in the process of dismounting, lose lead sealing screw or terminal cap easily, cause unnecessary loss; Also there is identical problem at the scene during the dress table.
Summary of the invention
The purpose of this utility model is the weak point that overcomes existing electric energy meter, provides a kind of terminal cap to overturn, and installation, verification are conveniently saved the anti-electricity-theft electric energy meter of cost, enhancing anti-stealing electricity function simultaneously.
The purpose of this utility model is achieved in that it comprises the table lid, nameplate, terminal cap, connection terminal, wiring board, O-ring seal, drain pan, the lead sealing screw, described wiring board is contained in the inner chamber of described drain pan, described connection terminal is installed in the described drain pan lower lumen, described nameplate is fixed on described table interior surface, described table lid and described drain pan top are with described lead sealing screw retention, the boss that the grab that its underpart adopts described table to cover hooks described drain pan inboard is fixed, described terminal cap is covered on described connection terminal, described terminal cap embeds table by the turning axle on it and covers in the rotating hole of two sides, and described terminal cap can be overturn.
Described terminal cap inside surface is provided with the waterproof outer ring, and described connection terminal surface is provided with the waterproof inner ring that is complementary with above-mentioned waterproof outer ring.
Described table lid two sides are provided with positive stop lug boss.
Described lead sealing screw top is provided with the lead sealing lid, and described lead sealing lid merges by ultrasonic soldering with described table lid.
Described lead sealing lid is made of plastics.
The beneficial effects of the utility model are: terminal cap can be overturn, and installs, verification is convenient and swift, saves cost, stops electricity filching behavior effectively, raises the efficiency.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.

Among the figure: 1. table covers; 2. lead sealing is covered; 3. nameplate; 4. terminal cap; 5. connection terminal; 6. wiring board; 7. O-ring seal; 8. drain pan; 9. grab; 10. boss; 11. lead sealing screw; 12. waterproof outer ring; 13. waterproof inner ring; 14. positive stop lug boss.
Embodiment
The technical scheme that the utility model adopted is: table cover 1 and drain pan 8 by lead sealing screw 11 fixing after, lead sealing lid 2 covers above lead sealing screw 11, lead sealing lid 2 and show to cover 1 and utilize ultrasonic soldering to merge.Like this; the outside does not have the position that can prize; promptly use the red iron wire sled lead sealing of burning to cover 2 surfaces; because lead sealing lid 2 covers 1 by ultrasonic soldering with table and merges, cannot pry open lead sealing lid 2, thereby protect lead sealing screw 11 not outwarded winding; even destroyed lead sealing lid 2; but anti-electricity-theft lead sealing material is plastics, cannot integer restore, and the surface directly can be found.Strengthened the anti-stealing electricity function of electric energy meter.Simultaneously, terminal cap 4 is fixing without lead sealing screw 11, embeds table by the turning axle on the terminal cap 4 and covers in the rotating hole of 1 two sides, when verification or installation electric energy meter, needn't repeat to install and remove the lead sealing screw 11 on the terminal cap 4.Raise the efficiency, save cost.
Above-mentioned terminal cap 4 can be to spin upside down structure, also can be left and right sides overturn structure.
In Fig. 4, connection terminal 5 is put into the downside inner chamber of drain pan 8, and connection terminal 5 surfaces are provided with waterproof inner ring 13.Terminal cap 4 is covered above connection terminal 5, terminal cap 4 inside surfaces are provided with waterproof outer ring 12, terminal cap 4 both sides are provided with turning axle, turning axle embeds table and covers in the rotating hole of 1 two sides, stir terminal cap 4 and cover connection terminal 5 surfaces, owing to be provided with inside and outside water proof ring, outside water can not enter connection terminal 5.
In Fig. 3, O-ring seal 7 embeds in the seal groove of drain pans 8, and wiring board 6 is contained in the inner chamber of drain pan 8, and nameplate 3 is contained in table and cover 1 inside surface, and table cover 1 and hooks the boss 10 of drain pan 8 inboards by bottom grab 9, shows to cover 1 top and fixes by lead sealing screw 11.As shown in Figure 2, lead sealing lid 2 covers above lead sealing screw 11, makes lead sealing lid 2 and table cover 1 fusion with ultrasonic soldering again and goes one.
In Fig. 5, electric energy meter can open terminal cap 4 when verification or installation, overturn downwards for preventing terminal cap 4, covers 1 two sides at table and is provided with positive stop lug boss 14.
