Abstract
The utility model discloses an intelligent three-phase electric energy meter. The intelligent three-phase electric energy meter comprises an upper box assembly and a pedestal, wherein the upper box assembly comprises an upper box body, the front end of the upper box is equipped with a screwed hole, the front end of the pedestal is equipped with a similar screwed hole, positions of the screwed holes are corresponding, the upper box body and the pedestal are fastened and connected via a nut matching with the screw holes, and a snap is arranged outside the screw hole of the pedestal so that positioning of the nut is reliable. According to the utility model, the snap is arranged on the pedestal, and the nut connecting the upper box body with the pedestal is locked with the pedestal, thereby decreasing the failure rate of die moulding in the prior art, shortening the production period, and saving the production cost; and under the condition that the nut is slipped, it is only required to replace the nut instead of discarding the whole bottom box.
Description
Technical field
The utility model relates to a kind of three-phase intelligent electric-energy meter.
Background technology
At present, the lower case assembly of electric energy meter adopts the produced by insert molding mode, nut is put into the mould die cavity of base in die molding process, and injection molding product is embedded in the end box nut.There is certain deficiency in this mode, and the cycle length that moulding is produced is longer, and production cost is higher, and causes easily mould to break down, and consumes the maintenance that manpower and materials are used for mould.
The utility model content
The purpose of this utility model is to provide a kind of structural safety, three-phase intelligent electric-energy meter that production cost is low.
This three-phase intelligent electric-energy meter that the utility model provides, comprise case assembly and base, upper case assembly comprises upper cartridge body, the front end of upper cartridge body and base has identical threaded hole corresponding to position, both are connected by the fastening nuts with this threaded hole coupling, threaded hole on the described base has grab outward, is used for making described nut location reliable.
The utility model is designed with grab at base, the attaching nut of upper cartridge body and base and base adopt the mode that clamps, reduced the formed in mould failure rate of prior art, shortened the production cycle, saved production cost, and occur at nut need not box of the whole end is scrapped under the situation of stripped thread, only need to change a nut and get final product.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A section structure for amplifying synoptic diagram among Fig. 1.
Embodiment
Shown in Fig. 1-2, this three-phase intelligent electric-energy meter that the utility model provides comprises case assembly 1, base 2, measuring apparatus 3; Upper case assembly 1 comprises upper cartridge body 11, and the front end of upper cartridge body 11 and base 2 has identical threaded hole corresponding to position, and both are fastenedly connected by the nut 4 with this threaded hole coupling, and the threaded hole on the base 2 has grab 21 outward, is used for making nut 4 location reliable.
The utility model is produced first base 2, then nut 4 is packed in the threaded hole of reserving on the base 2, and block nut 4 fixing by the grab 21 on the base 2, form base assembly, then with base assembly and upper cartridge body 11 assemblings, again assembly and measuring apparatus 3 assemblings of upper cartridge body 11 with base 2 are got final product.
