The technical solution of the utility model is, the utility model electric energy meter watchcase, and it comprises drain pan, the drain pan medial surface is provided with at least three pillars; Be equipped with rubber-like first opening that restriction first wiring board moves along the pillar axes direction on each pillar; At least one also is provided with second opening that moves along the pillar axes direction of restriction second wiring board in the described pillar, and second opening is in the elastic part that can be strutted by elasticity outside drain pan of pillar; Pillar except that the pillar that is provided with second opening all also is provided with restriction second wiring board along second projection of moving perpendicular to the direction of pillar axes.
After adopting said structure, the utility model compared with prior art has the following advantages: because the drain pan medial surface is provided with at least three pillars; Be equipped with rubber-like first opening that restriction first wiring board moves along the pillar axes direction on each pillar, like this, three first openings limit a plane, just can utilize first opening to clamp and fix first wiring board, when first wiring board is installed, first opening that can strut the pillar of drain pan one side is earlier put into first wiring board, one side part, then the other side that first wiring board is relative against the pillar that is positioned at the other side of drain pan to lower slider, in slipping into corresponding first opening; And at least one also is provided with second opening that moves along the pillar axes direction of restriction second wiring board in the described pillar, and second opening is in the elastic part that can be strutted by elasticity outside drain pan of pillar; Pillar except that the pillar that is provided with second opening all also is provided with restriction second wiring board along second projection of moving perpendicular to the direction of pillar axes, like this, second opening and second projection limit a plane, just can utilize second opening and second projection to clamp and fix second wiring board, when second wiring board is installed, can earlier the spacing hole of second wiring board be aimed at each second projection, second wiring board is taken advantage of a situation downwards then, can strut elastic part when the second wiring board upper limit hole and second projection are matched with hand elasticity outside drain pan, part, the second wiring board side snaps in second opening, thereby finishes installation; To sum up, the utility model need not screw first wiring board and second wiring board is installed, and has the wiring board of convenience and installs, and the high advantage of circuit plate efficiency is installed.
As improvement, the next door of described first opening is provided with and is used to limit first wiring board along first projection of moving perpendicular to the direction of pillar axes, and fixing of such first wiring board is more reliable.
As further improvement, described elastic part is provided with the guiding surface that conveniently struts it, can rely on the outer elasticity of a side direction drain pan of second wiring board that moves downward to strut elastic part like this, snap in second opening, promptly more convenient installation with the office of a side of convenient second wiring board.
As further improvement, described drain pan also is provided with at least one and limits second wiring board along the 3rd projection of moving perpendicular to the direction of pillar axes, and fixing of such second wiring board is more reliable.
As further improvement, described pillar is four, two one group, be located at respectively on two opposed inside faces of drain pan, and wiring board is stressed more even like this, more helps the protection to wiring board.
