Abstract
The utility model discloses an electric energy meter casing which includes a casing shell (1) provided with a card slot (1.1), and a card slot baffle plate (2). The card slot baffle plate (2) is hinged with the casing shell (1), and the undersurface of the card slot baffle plate (2) near a hinge shaft is a cambered surface (2.1). The electric energy meter casing can prevent the water from entering into the electric energy meter via the card slot, thus guaranteeing the performance of the electric energy meter.
Description
Technical field
The utility model relates to the electric energy meter technical field, specifically is a kind of electric energy meter case.
Background technology
A kind of plug-in card electric energy meter is arranged at present, and it comprises the case housing, and the front of this case housing is provided with the draw-in groove that is used for plug-in card, the medial surface of this draw-in groove is provided with the draw-in groove baffle plate, this draw-in groove baffle plate is hinged by torsion spring and case housing, makes the draw-in groove baffle plate be close to the case housing all the time, to block draw-in groove.There is following shortcoming in the electric energy meter case of prior art: because the lower surface of draw-in groove baffle plate is a plane, and the inside surface of the hinge axis of draw-in groove baffle plate and case housing is at regular intervals, after the draw-in groove baffle plate is installed like this, there is the gap between the lower surface of draw-in groove baffle plate and the case housing, make the draw-in groove baffle plate not block draw-in groove fully like this, extraneous water is entered from draw-in groove, thereby influence the performance of electric energy meter.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of water of avoiding to enter from draw-in groove, thereby guarantee the electric energy meter case of electric energy meter performance.
The technical solution of the utility model is, a kind of electric energy meter case with following structure is provided, it comprises case housing and the draw-in groove baffle plate that is provided with draw-in groove, and described draw-in groove baffle plate and case housing are hinged, and described draw-in groove baffle plate is a cambered surface near the lower surface of jointed shaft one side.
After adopting said structure, the utility model electric energy meter case compared with prior art, have the following advantages: because the lower surface of close jointed shaft one side of described draw-in groove baffle plate is a cambered surface, from said structure as seen, the technical scheme of the utility model electric energy meter case is to have guaranteed draw-in groove baffle plate and the applying of case housing medial surface in fact, make between draw-in groove baffle plate and the case housing very close to each otherly, avoid water to enter, thereby guarantee the electric energy meter performance from draw-in groove.
Description of drawings
Figure is the cross-sectional view of the utility model electric energy meter case.
Shown in the figure, 1, the case housing, 1.1, draw-in groove, 2, the draw-in groove baffle plate, 2.1, cambered surface.
Embodiment
Below in conjunction with accompanying drawing the utility model electric energy meter case is described further.
As shown in the figure, electric energy meter case of the present utility model, it comprises case housing 1 and the draw-in groove baffle plate 2 that is provided with draw-in groove 1.1, described draw-in groove baffle plate 2 is hinged with case housing 1, be that both link together by torsion spring, described draw-in groove baffle plate 2 is a cambered surface 2.1 near the lower surface of jointed shaft one side.
Claims (1)
