This utility model is further arranged to: the height of described locating piece distance back seat is more than the height of circuit board distance back seat.
By using technique scheme so that locating piece is while playing locating effect, the most protruding at circuit board surface, is supported between cover cap and circuit board, it is to avoid cover cap extrudes circuit board after being affected deformation by fortuitous event and causes circuit board damage.
This utility model is further arranged to: described locating piece is provided with buckle towards the side outside housing, described cover cap is provided with and the draw-in groove of buckle clamping.
By using technique scheme, further with the structure of locating piece so that locating piece also has and connects and fixes the effect of cover cap with cover cap.
This utility model is further arranged to: the end bosses of described sidewall has the waterproof ring that a circle edgewise is arranged, and this waterproof ring is closely connected with the medial wall of cover cap.
By using technique scheme, by the setting of waterproof ring, add from housing to climbing water distance in housing, be effectively improved the water proof and dust proof effect of housing.
This utility model is further arranged to: the end face of described mounting post offers screwed hole, described circuit board is provided with this screwed hole just to installing hole.
By using technique scheme, facilitate the connection of circuit board and back seat.
Compared with prior art, the electric energy meter in this utility model has the advantage such as easy accessibility, circuit board safety, stability is high, housing is completely embedded, good water-proof effect.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made after reading this specification by those skilled in the art as required does not has the amendment of creative contribution, but as long as all being protected by Patent Law in right of the present utility model.
Embodiment 1: a kind of electric energy meter, including housing 1, housing 1 includes cover cap 2 and back seat 3, and this cover cap 2 is square frame-shaped structure with back seat 3, jointly has the opening that a shape is identical, and is combined the cavity forming closing by this vent cover.Sidewall 32 end bosses of back seat 3 has the waterproof ring 10 that a circle edgewise is arranged, and this waterproof ring 10 is closely connected with the medial wall 32 of cover cap 2, adds from housing 1 to climbing water distance in housing 1, is effectively improved the water proof and dust proof effect of housing 1.
Installing a circuit board 4 in cavity, and be equipped with 6 mounting posts 5 in back seat 3, mounting post 5 is positioned at the marginal position of cavity, keeps the adjacent intensity in order to two-way reinforcement mounting post 5 with back seat 3 sidewall 32 in the medial wall 32 with back seat 3.The end (i.e. mounting post 5 is towards one end of cover cap 2) of mounting post 5 is protruding outside the opening of back seat 3, and the top of mounting post 5 is provided with screwed hole, and circuit board 4 is by this screwed hole and is bolted in mounting post 5.It is in the position floated on back seat 3 by mounting post 5 holding circuit plate 4.
