Abstract
The utility model discloses an electric energy meter, including drain pan (1), first housing (2) and antenna terminal (3), drain pan (1) in lower part and first housing (2) connect, antenna terminal (3) establish the one side on drain pan (1) upper portion, drain pan (1) upper portion still sliding fit have second housing (4), second housing (4) and drain pan (1) on be equipped with the waterproof construction, drain pan (1) on be equipped with a baffle (5), baffle (5) and drain pan (1) between have passageway (6), second housing (4) on have breach (7) that supply the wire to pass, second housing (4) be connected with drain pan (1). This electric energy meter's antenna can be enough built -in, also can be external, can guarantee also that sleet water does not get into inside the electric energy meter simultaneously.
Description
Technical field
The utility model relates to a kind of electric energy meter.
Background technology
At present, electric energy meter has exterior antenna and inside antenna two kinds.Although exterior antenna signal is good, it is vulnerable to rain erosion and damages.Although inside antenna should not damage, its dtr signal.If directly inside antenna is caused outside by wire, then sleet water can be made again to enter electric energy meter inside and damage electric energy meter.Therefore, for these reasons, urgently need a kind of electric energy meter, the antenna of this electric energy meter can either be built-in, also can be external, also can ensure that sleet water does not enter electric energy meter inside, to solve the problem simultaneously.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of electric energy meter, and the antenna of this electric energy meter can either be built-in, also can be external, also can ensure that sleet water does not enter electric energy meter inside simultaneously.
The technical solution of the utility model is, provides a kind of electric energy meter, comprises drain pan, the first case and antenna terminal; Described drain pan middle and lower part is connected with the first case; Described antenna terminal is located at the side on drain pan top; Described drain pan top is also sliding combined with the second case; The second described case and drain pan are provided with waterproof construction; Described drain pan is provided with a baffle plate, has passage between described baffle plate and drain pan; The second described case there is the breach passed for wire; The second described case is connected with drain pan.
Described waterproof construction is: be provided with a flat board after described drain pan, be provided with a cavity between described flat board and drain pan, and described dull and stereotyped bottom is also provided with multiple opening flowed out that supplies water, and described opening is communicated with cavity; The second described case and flat board offset.
Polylith weather board is also provided with between described flat board and drain pan.
Polylith back up pad is also provided with between described flat board and drain pan.
Described flat board and drain pan bottom are at grade.
After adopting above structure, the utility model compared with prior art, has the following advantages:
When the utility model electric energy meter uses in sleet environment, directly worked by inside antenna.Use exterior antenna when other environmental works, can between by wire through passage, pull out from the breach of the second case, then place.Simultaneously due to the existence of waterproof construction, therefore, antenna is external does not damage electric energy meter to causing sleet water to enter electric energy meter inside.Therefore, the antenna of the utility model electric energy meter can either be built-in, also can be external, also can ensure that sleet water does not enter electric energy meter inside simultaneously.
As improvement, between described flat board and drain pan, be also provided with polylith weather board.Weather board be provided with the quick derivation being beneficial to water.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of electric energy meter of the utility model, comprises drain pan 1, first case 2 and antenna terminal 3; Described drain pan 1 middle and lower part is connected with the first case 2, is generally screw and connects; Described antenna terminal 3 is located at the side on drain pan 1 top; Described drain pan 1 top is also sliding combined with the second case 4, and there is chute 13 drain pan 1 both sides, and slide block 14 is arranged at the bottom of the second case 6, and described slide block 14 is slidably fitted in chute 13; The second described case 4 is provided with waterproof construction with drain pan 1; Described drain pan 1 is provided with a baffle plate 5, has passage 6 between described baffle plate 5 and drain pan 1; The second described case 4 there is the breach 7 passed for wire; The second described case 4 is connected with drain pan 1, and the second case 4 is connected with drain pan 1 screw.
Described waterproof construction is: described drain pan 1 is provided with a flat board 8 below, is provided with a cavity 9 between described flat board 8 and drain pan 1, and described flat board 8 bottom is also provided with multiple opening 10 flowed out that supplies water, and described opening 10 is communicated with cavity 9; The second described case 4 offsets with dull and stereotyped 8.
Polylith weather board 11 is also provided with between described flat board 8 and drain pan 1.
Polylith back up pad 12 is also provided with between described flat board 8 and drain pan 1.
Described flat board 8 and drain pan 1 bottom are at grade.
Described drain pan 1 middle and lower part and the first case 2 junction can also be connected with the O-ring seal of a ring-type.
Below only just most preferred embodiment of the present utility model is described, but can not be interpreted as it is limitations on claims.The utility model is not limited only to above embodiment, and its concrete structure allows to change.In every case the various change done in the protection domain of the utility model independent claims is all in protection domain of the present utility model.
