【発明の詳細な説明】
本発明は交叉コイル式計器等の電気計器のワイ
ヤ接続方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for connecting wires to electrical meters, such as crossed coil meters.
交叉コイル式計器の端子にはワイヤを固定、接
続する必要があるが、従来の物はワイヤの絶縁皮
膜除去を行つた後に端子に仮固定しはんだ付けを
行つていた。端子形状についても単にワイヤの固
定が容易となるような形状でしかなかつた。 Wires need to be fixed and connected to the terminals of cross-coil meters, but in conventional devices, the insulation coating of the wires has been removed, then the wires have been temporarily fixed to the terminals and soldered. The terminal shape was simply such that the wire could be easily fixed.
従つて、上述した従来のものでは、以下のごと
き欠点がある。 Therefore, the above-mentioned conventional device has the following drawbacks.
(1) ワイヤ絶縁皮膜は加熱除去する方法がとられ

イヤを端子にからげた後では、端子に熱をうば
われ、短時間での除去は困難であつた。(1) The wire insulation film was removed by heating, but this requires a fairly high temperature, so once the wire is tangled with the terminal, the heat is carried away by the terminal, making it difficult to remove it in a short time. It was hot.
(2) 端子のワイヤ固定部の近くには樹脂製ベース
があり、端子加熱時にベースの溶融、変形、変
色等がおこり、製品として好ましくなかつた。(2) There is a resin base near the wire fixing part of the terminal, and when the terminal is heated, the base melts, deforms, discolors, etc., and is not desirable as a product.
(3) 上記(1)，(2)の理由により従来はまず、ワイヤ

て、終つた後にワイヤの接続を上記方法にて行
つているので、全自動巻線機を採用する上では
その工程は困難である。(3) Due to reasons (1) and (2) above, conventionally, the insulation film is removed before the wire is tied to the terminal, and then the wire is tied to the terminal and soldered. In addition, with the intermediate terminal of a crossed coil type meter, it is necessary to pull out the wire just long enough to wrap it around the terminal, then wind the wire, and then connect the wire using the method described above after winding is complete. Therefore, it is difficult to use a fully automatic winding machine.

間により高温加熱が可能なことを目的とする。 In order to solve the above-mentioned drawbacks, the present invention provides a small-diameter portion in the terminal of a crossed coil type meter and allows an appropriate current to flow in the axial direction, thereby eliminating the local heat generation that occurs due to the low conductivity of that portion. By using this method, it is possible to remove insulation from wires and to solder the wires to terminals. Also, by providing a small diameter part on the terminal, it is easier to untangle the wires and improve work efficiency. The method of heating the terminal in the present invention uses self-heating of the terminal itself, which requires less energy loss than a method of heating from the outside, and allows localized heating, allowing accurate heating of only the wire tangles. The purpose is to heat the device to a high temperature with little effect on other parts, to be able to easily control and manage an appropriate current from the outside, and to be able to heat at a high temperature in a short period of time.
