Abstract
The utility model discloses a three-phase digital intelligent power meter, which comprises a back shell and a front shell, wherein sliding slots are arranged in the two side surfaces of the back shell; clamping strips are positioned at the front end parts of the sliding slots and respectively extend from the upper edges and the lower edges of the sliding slots to the centers of the sliding slots; screw holes corresponding to the positions of the sliding slots are arranged in the back end surface of the back shell; hardware brackets are arranged in the sliding slots and comprise connecting parts, first fixed parts formed at one end of the connecting parts in a bent manner, and second fixed parts formed at the other ends of the connecting parts in a bent manner; the first and second fixed parts are bent in opposite directions; the first fixed parts are connected onto the front shell; holes are arranged in the second fixed parts; and the second fixed parts are fixedly arranged on the back shell through using bolts to pass through the holes and the screw holes. Since the hardware brackets are arranged on the structure, the connection strength and reliability are improved.
Description
Technical field
The utility model relates to several intelligence electric instruments.
Background technology
Continuous propelling along with Utilities Electric Co.'s intelligent grid " informationization, robotization, interactive " construction; In September, 2009; State Grid Corporation of China has unified surface structure, size model, calibrating index and the standard of intelligent electric energy meter; And since 2009, intelligent electric energy meter was economized measurement centre of net company by each then and is unified storage, calibrating and dispensing by State Grid Corporation of China's centralized purchasing; The primary structure of existing several intelligence electric instruments comprises back cover, fore shell, be located at glass and button on the fore shell, be located at the circuit board in the back cover; Fore shell and back cover are through screw retention, and the defective of this structure is: only through screw retention fore shell and back cover, its fixing fastness is unreliable.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of three number of phases intelligence electric instruments.
The technical scheme that solves the problems of the technologies described above is: three number of phases intelligence electric instruments, comprise back cover and fore shell, and fore shell is installed on the back cover; Fore shell has a window, and the window place is equipped with glass, and button is installed on fore shell; The two sides of back cover are provided with chute, and the leading portion portion that is positioned at chute is extended with card article to the center respectively from the last lower limb of chute, on the rear end face of back cover, is provided with and the corresponding screw of runner position; Be provided with the five metals support in the chute; First fixed part that the five metals support comprises connecting portion, be bent to form from connecting portion one end, second fixed part that is bent to form from the connecting portion other end; The overbending direction of first fixed part and second fixed part is opposite; First fixed part is connected on the fore shell, and second fixed part is provided with the hole, passes the hole and screw is fixed on the back cover through bolt.
As improvement, be formed with a convex tendon through punching press on the connecting portion.
As improvement, on the inwall of back cover, be provided with circuit board draw-in groove is installed.
As improvement, the end face of button is a circular arc.
The beneficial effect of the utility model is: owing to be provided with the five metals support, therefore, improved the intensity and the reliability that connect; Owing to be provided with convex tendon, therefore, improved the intensity of five metals support itself, improve the anti-bending of connecting portion deformation ability; Owing to be provided with draw-in groove, therefore, be convenient to install the subcard of length elongated, also be convenient to location to the subcard installation position; Because the section of button is an arc surface, therefore, has strengthened feel, outward appearance is also more attractive in appearance.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further elaborated.
Three number of phases intelligence electric instruments comprise back cover 1, fore shell 2, glass 3, button 4, circuit board (not shown), five metals support 5.Back cover 1 and fore shell 2 are connected through screw, are formed with accommodation space between back cover 1 and the fore shell 2; On fore shell 2, have window, described glass 3 is installed on the window.As shown in Figure 2, be provided with draw-in groove 11 in the described back cover 1, the dual-side holding of circuit board is carried out stationary positioned through this mode to circuit board in draw-in groove 11.To shown in Figure 5, the two sides of back cover 1 are provided with chute 12 like Fig. 1, and the leading portion portion that is positioned at chute 12 is extended with card article 13 to the center respectively from the last lower limb of chute, on the rear end face of back cover 1, is provided with and the corresponding screw 14 of runner position.Extremely shown in Figure 15 like Figure 11; First fixed part 52 that five metals support 5 comprises connecting portion 51, be bent to form from connecting portion one end, second fixed part 53 that is bent to form from the connecting portion other end; The overbending direction of first fixed part 52 and second fixed part 53 is opposite; First fixed part 52 is connected on the fore shell 2, and second fixed part 53 is provided with hole 54, passes the hole and screw is fixed on the back cover through bolt; In order to improve the intensity of connecting portion itself, on connecting portion 51, be formed with convex tendon 55 through punching press; After five metals support 5 installed, the front end holding of connecting portion prevented that connecting portion breaks away from back cover between two card articles, like this, just improved the intensity and the reliability that connect.Shown in figure 10, the end face 41 of button is a circular arc, to strengthen feel, beautifies outward appearance.
