Abstract
The utility model discloses an electric energy meter casing which comprises a bottom casing (1), a cover casing (2) and a circuit board (3). The circuit board (3) is fixed in the bottom casing (1), and a casing fastening device which is convenient to install and good in anti-theft performance is arranged on the bottom casing (1) and the cover casing (2). The electric energy meter casing is convenient to install and good in anti-theft performance.
Description
Technical field
The utility model relates to the electric energy meter technical field, specifically is a kind of electric energy meter housing.
Background technology
The electric energy meter housing of prior art comprises drain pan, case and wiring board, and described wiring board is fixed in the drain pan, and described drain pan is connected or ultrasonic soldering with the case screw.There is following defective in the electric energy meter housing of said structure in the use of reality: though screw retention drain pan and case are easy for installation, its theftproof performance is poor.The ultrasonic soldering theftproof performance is good, and is inconvenient but it is installed, and if there is a piece housing not weld, and very easily is destroyed and influences theftproof performance.
The utility model content
The technical matters that the utility model will solve is, overcomes the defective of above prior art, and a kind of easy for installation and electric energy meter housing that theftproof performance is good is provided.
The technical scheme of the utility model is, a kind of electric energy meter housing is provided, and comprises drain pan, case and wiring board, and described wiring board is fixed in the drain pan, and described drain pan and case are provided with housing fastening device easy for installation and that anti-theft is good.
Described housing fastening device comprises and is located on the drain pan and stretches out the outer box of drain pan and be located at the pin thread on the case; Described box is provided with groove; Described pin thread is provided with the breach that supplies box to slip into, and is provided with the trapezoidal projection that matches with the groove size shape in the described breach.
After adopting above structure, the utility model compared with prior art has the following advantages:
The utility model electric energy meter housing only need insert drain pan with case when mounted, makes trapezoidal projection embed groove and gets final product, and therefore installs very convenient.Because the housing fastening device is located in the housing, therefore be difficult for being destroyed, its theftproof performance is good.
As improvement; Said wiring board at the height on the drain pan a little less than the height of box on drain pan; Be provided with the gap that is slightly less than trapezoidal bump height between described wiring board and the box, when case inserted or take out drain pan, box produced deformation and is propped up by wiring board; Therefore not only install firmly, and its theftproof performance is very good.
Description of drawings
Accompanying drawing is the structural representation of the utility model electric energy meter housing.
Shown in the figure 1, drain pan, 2, case, 3, wiring board, 4, box, 5, pin thread, 6, groove, 7, breach, 8, trapezoidal projection, 9, pillar.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Shown in accompanying drawing; A kind of electric energy meter housing of the utility model; Comprise drain pan 1, case 2 and wiring board 3, described wiring board 3 is fixed in the drain pan 1, and drain pan 1 inner bottom surface is provided with four pillars 9; Described wiring board 3 is screwed on four pillars 9, and described drain pan 1 is provided with housing fastening device easy for installation and that anti-theft is good with case 2.
Described housing fastening device comprises and is located on the drain pan 1 and stretches out the outer box of drain pan 14 and be located on the case 2 and box 4 positions pin thread 5 one to one; Described box 4 is provided with groove 6; Described pin thread 5 is provided with the breach 7 that supplies box 4 to slip into, and is provided with the trapezoidal projection 8 that matches with groove 6 size shape in the described breach 7.
Said wiring board 3 at the height on the drain pan 1 a little less than the height of box 4 on drain pan 1; Be the upper surface of the upper surface of wiring board 3 a little less than box 4; Box 4 can be propped up by the side of wiring board 3 when outward-dipping; Be provided with the gap (not shown) that is slightly less than trapezoidal projection 8 height between described wiring board 3 and the box 4, make box 4 when distortion, propped up and the fastness that reduces stolen possibility and increase housing by wiring board 3.
Below only be described, but can not be interpreted as it is restriction claim with regard to the most preferred embodiment of the utility model.The utility model is not limited only to above embodiment, and its concrete structure allows variation.In every case the various variations of in the protection domain of the utility model independent claims, being done are all in the protection domain at the utility model.
