電力量計が製造されている。The conventional manufacturing method of a watt-hour meter, as shown in FIGS. 2 to 5, includes a base (1) formed from a cold-rolled steel sheet or a galvanized steel sheet and a latch (2) formed from an austenitic stainless steel sheet. ), or similarly the base (1) and the lug (3) formed from an austenitic stainless steel plate, or similarly the base (1) and a guard formed from a cold-rolled steel plate or a galvanized steel plate. (4) are joined by projection welding or nubot welding, and then a coating film (9) of approximately 20μ is formed by electrodeposition coating for rust prevention, and then coated on top of it by electrostatic powder coating. A film (9) with a thickness of about 100 μm is formed. Then, attach the energy meter parts (not shown) to the base (
1) and the guard (4), attach the sensor cover (6) shown in Figure 3 or the band (6) shown in Figure 4.
5) By attaching a glass cover (not shown) etc. to the base (1) by tightening the screws,
Electric energy meters are manufactured.

れている。However, base (1) and latch (2) or base (1)
) and the lug (3), or the base (1) and the guard (4), are manufactured as described above, so their cross-sectional structure is such that there is no void around the weld, as shown in Figure 5. Department (
8) occurs, and the coating film (9) is not formed on that part. Therefore, rust occurs from this gap (8), and in order to prevent this, it is necessary to form a correction coating 11'lu (10) on this area as shown in FIG. This correction painting is difficult to automate and is performed manually.
従来の電力量計は以上の様に製造されているため、前記
の如く人手による補正塗り工程に多大な労力を要してお

に接合強度の低下、さらには破損するという問題点があ
った。Conventional watt-hour meters are manufactured in the manner described above, and as mentioned above, the manual correction coating process requires a great deal of effort. There were problems such as a decrease in performance and even damage.
また、例えば掛金（２）は電力量計全体を長年月にわた
って保持せねばならず、高強度な接合が要求されている
。Further, for example, the latch (2) must hold the entire watt-hour meter for many years, and is required to have a high-strength connection.
この発明は上記のような問題点を解消するためになされ

に各接合部の接合強度を大きくすることができる電力量
計の製造方法を得ることを目的とする。This invention was made to solve the above-mentioned problems, and aims to manufacture a watt-hour meter that can prevent rust from occurring without the need for correction coating and further increase the joint strength of each joint. The purpose is to obtain a method.
上記目的を達成するために、この発明に係る電力量計の

着剤を併用した工法により製造するものである。In order to achieve the above object, a method for manufacturing a watt-hour meter according to the present invention uses a method in which each joint between the base and the latch, the pace and the lug, or the base and the guard is welded together using an adhesive. It is something to do.
この発明においては、空隙部に接着剤が充填されるので
、この部分からの錆の発生が防止される。In this invention, since the gap is filled with adhesive, rust is prevented from forming in this area.
以下この発明の一実施例を図について説明する。 An embodiment of the present invention will be described below with reference to the drawings.
沁１図はペース（１）と掛金（２）との接合部の断面構

適量、即ち第６図の空隙部（８）が充填される程度の量
を接合しようとする部分へ塗布し、その後従来と同様の
方法によりフロジエクション溶接を行う。Figure 1 shows the cross-sectional structure of the joint between the pace (1) and the latch (2). When joining the base (1) and latch (2), first apply anoleminium or zinc to the joint part.
Apply an appropriate amount of epoxy adhesive (11) containing metal powder such as iron, that is, enough to fill the void (8) in Figure 6, to the parts to be joined, and then apply the same amount as before. Flogeection welding is performed by the method.
これにより、溶接部（７）は従来と同様に金属同志の溶

ことができる。Therefore, rust does not occur from the gap (8) shown in FIG. 5 as in the conventional case, and there is no need to apply a correction coating to prevent this. Furthermore, in addition to the conventional welding strength, the bonding strength due to the adhesive (11) is added, and a high-strength bond can be obtained.

。After that, painting is carried out using the same method as before, but since the adhesive (11) contains metal powder such as aluminum, zinc, or iron as described above, it has electrical conductivity, and electrodeposition coating is not possible. It can be done easily. In this case, the adhesive (
No. 11) undergoes a complete curing reaction during the baking process in electrodeposition coating or electrostatic powder coating, and exhibits high reliability over a long period of time. Thereafter, manufacturing is carried out in the same manner as in the past, but the step of forming a correction coating film is not necessary.

る効果がある。(5) As described above, according to the present invention, when each joining the base and the latch, the lug, or the guard, the adhesion is performed at the same time as welding, and the gap in the joint is filled with adhesive. This has the effect of preventing rust from forming in this area, eliminating the need for the labor-intensive correction coating work that was previously performed, and increasing the joint strength of each joint. be.
