Abstract

The utility model discloses a single-phase LCD/register carrier wave electric energy meter provided for an electric user to measure the electricity quantity, comprising a base housing, a display device, a name plate, a meter cover, a wire connecting terminal, a terminal cover and a hanging hook; wherein, the display device is arranged in the base housing in the method of liquid crystal display or the register. The meter cover covers the base housing and is pressed by the name plate in the middle part. Grooves are provided on the periphery of the upper edge of the base housing and the periphery of a terminal block. Sealing rings are arranged in the grooves. The meter cover and the terminal cover are respectively fastened on the base housing and the terminal block through the sealing ring, which facilitates the sealing effect to be sounder and has shift and convenient installation; furthermore, the traditional copper insert method on the base housing is changed, and the novel square form setting-in nut installation method is adopted. As a square-shaped nut can be replaced, the availability of the base housing is improved and cost is lower. The bolt fixing method of the name plate is cancelled, and the upper pressure type fixing method is adopted by the name plate through an upper cover; therefore, the shortcoming that the bolt can be seen after the transparent upper cover is effectively avoided. The utility model has the advantages of simple and manifest structure, simple proposal and convenient installation.

Description

Single-phase LCD/ register carrier electric energy meter

Technical field

The utility model relates to a kind of electric energy meter, and is especially a kind of for what single-phase LCD/ register carrier electric energy meter of electricity consumer metering power consumption.

Background technology

At present all electronic electric energy meters all have following not enough the need and improve: drain pan and table lid and and terminal block between sealing respectively, many employing " O " shape O-ring seals, the not good and complex structures of sealing effectiveness; Nameplate adopts screw retention, if use transparent upper cover just to be difficult to avoid making screw to expose, not only structure was loaded down with trivial details but also influence attractive in appearance; Drain pan adopts the copper insert mode, and inconvenience is changed, and has reduced usage degree, and flexibility ratio is relatively poor, can't change in case damage; The lead sealing screw is dashed forward in little cap surface more in addition, be not easy to vanning, and outward appearance plasticity is relatively poor; Drain pan mostly is linear structure, has not only influenced casing rigidity but also not attractive in appearance.

Summary of the invention

The purpose of this utility model is to overcome prior art above shortcomings part, and a kind of new-style electronic electric energy meter of economical and practical, rational in infrastructure, easy for installation, good sealing effect is provided.

The purpose of this utility model is achieved in that including drain pan, display, nameplate, table lid, connection terminal, terminal cap and hook forms, described display is contained in the drain pan, table covers on drain pan, be provided with groove around described drain pan upper edge periphery and the terminal block, in groove, be embedded with O-ring seal, described table lid and terminal cap are buckled in respectively on drain pan and the terminal block by O-ring seal, and described drain pan is provided with embedded nut.

Described O-ring seal is 8 fonts.

Described embedded nut is installed in the top and the Lower Half of drain pan.

Described drain pan bottom is fixed with connection terminal.

The last plane of described terminal cap is provided with pit.

Described pit is circular, oval, rhombus and square.

Described nameplate is pressed between the table lid and bottom shell.

Described hook is inlaid in the groove at back, drain pan upper end.

Described hook is an inverted U, and its two bottom sides is provided with dop.

The side of described drain pan, table lid and terminal cap is an arcwall face.

Because the utility model has adopted said structure, compared with prior art has the following advantages:

1. figure of eight O-ring seal is adopted in the lid sealing of drain pan and terminal block sealing and drain pan and table, and adopts the PVC made, makes good sealing effect, convenience quick for installation.

2. nameplate cancellation screw retention adopts by loam cake and to go up pressure type and fix, and has avoided the visible drawback of screw behind the use transparent upper cover effectively, simple for structurely understands that technology is simple, and is easy for installation.

3. oblong pits is adopted in tegillum lead sealing place, makes that the plane is lower than the tegillum plane on the lead sealing screw, and lead sealing screw and table body one integrated mass are elegant in appearance.

4. drain pan changes traditional copper insert mode, has adopted novel square embedded nut mounting means, owing to the convertibility of square nut, has increased the availability of drain pan, provides cost savings.

5. drain pan and terminal cap adopt the arc line type structure, have increased the intensity of table body, prevent the side distortion, increase visual effect simultaneously.

The utility model is compared with existing electronic electric energy meter, has to use gib screw less, and save cost, and can accelerate assembling speed, the exterior flow line style, elegant in appearance, complete function is flexible.
