Description
本発明は、高周波加熱装置の電流ヒューズ部の構成に関するものである。 The present invention relates to a configuration of a current fuse portion of a high-frequency heating device.
従来の高周波加熱装置の電流ヒューズ部の一例を図４に示す（例えば、特許文献１参照）。図４は、特許文献１に記載された従来の高周波加熱装置の電流ヒューズ部のノイズフィルター基板の正面図である。図４に示すように、プリント基板１にリード付き電流ヒューズ２がハンダ付けされている。 An example of a current fuse portion of a conventional high-frequency heating device is shown in FIG. 4 (see, for example, Patent Document 1). FIG. 4 is a front view of the noise filter substrate of the current fuse portion of the conventional high-frequency heating device described in Patent Document 1. As shown in FIG. 4, a current fuse 2 with leads is soldered to the printed circuit board 1.
もう一例を図５に示す（例えば、特許文献２参照）。図５は、特許文献２に記載された従来の高周波加熱装置の電流ヒューズ部のノイズフィルター基板の外観図である。図５に示すように、プリント基板１にヒューズホルダ６がハンダ付けされており、ヒューズホル
ダ６には管形電流ヒューズ７がはめ込まれている。
上記従来の高周波加熱装置の電流ヒューズ部は、電流ヒューズにリード付き電流ヒューズを使用した場合、プリント基板にハンダ付けされているので、市場でヒューズが溶断し交換サービスする時に、最近はハンダ付けの信頼性などの観点からリード付き電流ヒューズのみを交換する事はほとんどなく、プリント基板ごとの交換が通例であり、サービス費用が高くなるという課題を有していた。 The current fuse part of the above conventional high-frequency heating device is soldered to the printed circuit board when a current fuse with a lead is used as the current fuse. From the viewpoint of reliability and the like, only the current fuse with lead is rarely replaced, and replacement for each printed circuit board is common, and there is a problem that the service cost becomes high.
なお、上記従来例はノイズフィルター基板にリード付きヒューズがハンダ付けされているが、高周波加熱装置の制御基板にリード付きヒューズがハンダ付けされている場合も多々あり、その場合は、制御基板の方がノイズフィルター基板より高価なので、サービス費用がさらに高くなるという課題を有していた。 In the above conventional example, the fuse with lead is soldered to the noise filter substrate, but there are many cases where the fuse with lead is soldered to the control substrate of the high-frequency heating device. However, since it is more expensive than the noise filter substrate, there is a problem that the service cost is further increased.
一方、電流ヒューズに管形電流ヒューズを使用した場合は、ヒューズホルダが必要だが、電気用品安全法によって、ヒューズホルダとヒューズの接触部の温度上昇には温度限度が設けられているので、ヒューズを冷却するために、冷却ファンによる冷却をしたり、冷却するための部品を追加するなど、性能面での制約やコスト高になるという課題を有していた。 On the other hand, when a tubular current fuse is used as the current fuse, a fuse holder is required. However, due to the Electrical Appliance and Material Safety Law, there is a temperature limit for the temperature rise at the contact point between the fuse holder and the fuse. In order to cool, there are problems such as cooling by a cooling fan or adding parts for cooling, resulting in restrictions on performance and high costs.
本発明は、リード付きヒューズを使用することにより、電気用品安全法による温度限度はないので、ヒューズを冷却するための性能面での制約やコスト高になる事がなく、かつ市場でヒューズが溶断し、交換サービスする時でもプリント基板ごとの交換が不要で、ヒューズのみを交換する事が出来るので、サービス費用も安価ですむ高周波加熱装置の電流ヒューズ部を提供することを目的とする。 Since the present invention uses a leaded fuse, there is no temperature limit according to the Electrical Appliance and Material Safety Law, so there is no performance limitation or cost increase for cooling the fuse, and the fuse is blown in the market. However, it is an object of the present invention to provide a current fuse portion of a high-frequency heating apparatus that does not require replacement for each printed circuit board even when performing replacement service, and can replace only the fuse, so that the service cost is low.
上記従来の課題を解決するために、本発明の高周波加熱装置の電流ヒューズ部は、プリント基板にハンダ付けされた第１リード付き電流ヒューズと、プリント基板上に設けられ前記第１リード付き電流ヒューズの一対のリードとそれぞれ電気的に接続された一対のプリント基板側接続端子と、前記プリント基板とは別体の第２リード付き電流ヒューズと、前記第２リード付き電流ヒューズの一対のリードの端部に固定された電流ヒューズ側接続端子と、を有し、前記第１リード付き電流ヒューズが溶断した時、前記第２リード付き電流ヒューズは、前記電流ヒューズ側接続端子を介して、前記プリント基板側接続端子と電気的かつ機械的に接続する事により、電気用品安全法による温度限度はないので、ヒューズを冷却するための性能面での制約やコスト高になる事がない。 In order to solve the above problems, a current fuse of the high frequency heating apparatus of the present invention includes a first lead with a current fuse which is soldered to the PCB, the first lead with a current provided on the printed circuit board A pair of printed circuit board side connection terminals respectively electrically connected to the pair of leads of the fuse, a current fuse with a second lead separate from the printed circuit board, and a pair of leads of the current fuse with the second lead A current fuse-side connection terminal fixed to an end, and when the current fuse with the first lead is blown, the current fuse with the second lead is connected to the print via the current fuse-side connection terminal. by connecting the substrate-side connecting terminals electrically and mechanically, the temperature limit is not due DENAN, in performance for cooling the fuse Not be made in about and high cost.
また、市場でヒューズが溶断し、交換サービスする時はリード付き電流ヒューズの両端に電気的に接続された接続端子にサービス専用ヒューズを取り付ける事により、ヒューズのみの交換が可能となり、プリント基板ごとの交換は不要になるので、サービス費用も安価ですむものである。 In addition, when a fuse is blown in the market and a replacement service is performed, it is possible to replace only the fuse by attaching a dedicated service fuse to the connection terminals electrically connected to both ends of the current fuse with leads. Since no replacement is required, the service cost is low.
