Problems solved by technology

[0002] In order to prevent the ammeter from being opened at will, the existing ammeters all adopt such figure 1 In the lead seal structure shown, screw holes (not shown in the figure) and lugs 40 with wire holes are provided on the upper cover 1 of the electric meter, and threaded columns (not shown in the figure) are provided in the base 2 of the electric meter. out), the threaded column is embedded with a nut (not shown in the figure), and the lead seal screw 10 with a threading hole is passed through the screw hole of the upper cover 1 and connected with the nut in the threaded column of the base 2 to make the upper cover 1 Connect and fix with the base 2, then pass the lead seal wire 30 through the wire hole of the lug 40 and the wire hole of the lead seal screw 10 respectively, and finally seal and fix the two ends of the lead seal wire 30 through the lead seal block 20, this The lead-sealed screw 10 has a threading hole, which makes its cost higher, and the nut embedded in the threaded column also makes the cost increase. At the same time, the production process is more complicated and the production efficiency is low. Therefore, the lead-sealed structure of this traditional electric meter There are the following disadvantages: complex structure, high cost, low production efficiency
