【発明の詳細な説明】 ［発明の目的］ （産業上の利用分野） 本発明は電子式電力量計の封印構造に関する。[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a sealing structure for an electronic watt-hour meter.
（従来の技術〉
電力量計の封印には日本電気計器検定所で行なわれる検
定封印と電力量計を需要家に取り付けて配線等を終了し
たときに行う電力封印とがある。(Prior Art) There are two types of sealing methods for power meters: the verification seal performed at the Japan Electric Meter Inspection Institute, and the power seal performed when the power meter is attached to a consumer and wiring etc. are completed.
検定封印は、各需要家で計量される電力量に格差を生じ

を行うものとなっている。The certification seal is made by adjusting the internal circuit to make the accuracy of each electronic watt-hour meter the same so that there is no disparity in the amount of electricity measured by each consumer. This is done to prevent the person from being forcibly tampered with from the outside. On the other hand, power sealing is performed to prevent improper measurement of power due to wiring such as power lines being changed after the electronic power meter is installed. Therefore, in an inductive watt-hour meter as shown in FIG. 4, verification seals 2 are performed on both sides of the main body 1, and power seals 4.5 are performed on the top surface of the terminal cover 3 where power lines and the like are wired. There is. The specific structure of these seals 2.4.5 is, for example, the electric power seal 4, as shown in FIG.
is provided on the terminal cover 3, and a sealing wire 9 is inserted between this sealing hook end 6 and the sealing hole 8 of the sealing screw 7 that tightens the terminal cover 3 to the main body 1, and this sealing wire 8 is formed into a ring shape to seal it. It is supposed to be carried out.

が現状である。(Problem to be solved by the invention) However, when sealing is performed, if the structure shown in Figure 5 is simply applied to an electronic watt-hour meter, for example, the installation of the consumer may not match the position. Even if you design it for its appearance, it will spoil its appearance. For this reason, without impairing the function of each seal,
At present, there is a desire for a sealing structure that is suitable for electronic watt-hour meters.
そこで本発明は、検定封印および電力封印を外観に影響
