Description
【０００１】
【発明の属する技術分野】
本発明は、電気加熱部品の構造に関するもので、特に家庭用電気用品のクッキングヒーターのフィッシュロースター部分に用いる加熱用の発熱体に関するものである。
【０００２】
【従来の技術】
従来、この種の導電体を印刷焼成してなる面状発熱体の電極は、特開平１１−４０３３０号公報に開示されるごとく、金属粒子の焼結体からなる導電体上に半田を用いて端子ピンを接合せしめるか、銀ろう等で接合していた。
【０００３】
この従来例について図５で説明する。セラミック製の板状体からなるヒーター板１８に銀−鉛の焼結体１５を焼付け、パターンを形成し、この表面に金属被覆層１６を析出させて発熱体としたものである。さらに電源との接続を確保するために端子を取り付ける部分に半田層１７を形成し、半田層１７の上に端子ピン１４を載置して加熱し、発熱体の表面に端子ピン１４を取り付け接合したものである。
【０００４】
【発明が解決しようとする課題】
前記、図５（特開平１１−４０３３０号公報）に開示される方法で電極を構成した発熱体では、電極（端子ピン）を保持する半田層と金属被覆層および金属粒子焼結体からなる導電体が数１００μｍと薄いことから、電極に外力を加えた場合導電体が基板から剥離断線し発熱不能になるという欠点があった。
【０００５】
【課題を解決するための手段】
本発明はかかる欠点を解決するもので、電極の取り付け構成を常に導電体を基板に押し付ける応力となる構成にし、電極に外力が加わっても導電体が基板から剥離断線せず発熱不能にならないものとした。
【０００６】
具体的には、電極は略円筒状の筒部と中心部に筒部と並行する方向に形成したピン状のネジ部と、前記ネジ部の反対側に前記ネジ部と同軸上に設けた円柱形状のピンもしくはネジとで構成し、前記電極の筒部を電圧供給部分に圧接せしめるべく前記ネジ部を電圧供給部分の丸穴を介して前記金属を貫通する穴を通し、さらに絶縁部材と平ワッシャとを介しナットで締め付け、前記ネジ部の反対側に設けた前記ピンもしくはネジにリード線を固定が出来る構成としたものである。
【０００７】
【発明の実施の形態】
本発明は、平板状の金属の表面に電気絶縁性を有する塗料を塗布焼付けし、その上に銀を主成分とする導電体を印刷、焼成し、この導電体の端部に金属製の電極を取り付けてなる発熱体において、導電体の端部の電圧供給部分は導電体のパターンを略円状にし中心部に丸穴を設けた構成とするとともに、電極は略円筒状の筒部と中心部に筒部と並行する方向に形成したピン状のネジ部とで構成し、前記電極の筒部を電圧供給部分に圧接せしめるべく、ネジ部を電圧供給部分の丸穴を介して金属を貫通する穴を通し、さらに中心部に前記電極のネジ部を貫通させる穴部と穴部の一方向外周に筒状の壁を設けた絶縁部材と、平ワッシャとを介しナットで前記電極のネジ部を締め付けて発熱体を構成したものである。
【００１２】
【実施例】
以下本発明の一実施例を図面に基づいて詳細に説明する。図１は本発明の一実施例を示す発熱体の分解斜視図である。図２は同じく平面図であり、図３は図２のＡ−Ａ断面図である。また、図４は図２のＢ−Ｂ断面図を示すもので、要部の詳細図である。
【００１３】
図において、図１は本実施例の特に電圧供給部分の斜視図であり、平板状のステンレス材などからなる金属１表面に、８００℃まで絶縁性を有するセラミック系の電気絶縁性を有する塗料２を塗布焼付けし、その上に銀を主成分とする導電体３を印刷、焼成してある。
【００１４】
４は電圧供給部分で導電体３の端部であり、後述する電極６を取り付ける部分である。この電圧供給部分４は導電体３のパターンを略円状にし中心部に前記金属１を貫通する穴と同心円となる丸穴５を設けた構成としてある。
【００１５】
６は金属製の電極であり、本実施例では真鍮（銅合金）もしくは鉄合金にニッケルめっきを施したものからなっている。電極６は略円筒状の筒部６ａと中心部に筒部６ａと並行する方向にピン状に形成されたネジ部６ｂとで構成されているものである。
【００１６】
７は絶縁部材であり、セラミックもしくは四フッ化エチレン樹脂からなり、その構成は中心部に前記電極６のネジ部６ｂを貫通させる穴部７ａと穴部７ａの一方向外周に筒状の壁７ｂを設けたものである。
【００１７】
また、８は平ワッシャであり、９はナットである。１０は前記各部品から構成されている発熱体である。
【００１８】
以上の構成において、導電体３の電圧供給部分４に電極６を取り付けるには、電極６のネジ部６ｂを電圧供給部分４の丸穴５を介して金属１の貫通穴に挿入する。その状態で下方から絶縁部材７の穴部７ａをネジ部６ｂに差し込み、平ワッシャ８を嵌めた後、ナット９をネジ部６ｂに締め付ける。これにより、電極６の筒部６ａを電圧供給部分４に圧接できるものであり、この状態で発熱体１０が完成するものである。
【００１９】
図３は発熱体１０の断面図であり、発熱体１０の導電体３表面の電圧供給部分４を避けて、さらに電気絶縁性を有する塗料１１を塗布焼付けした状態を示している。
【００２０】
図４は発熱体１０の要部断面拡大図であり、電極６は電圧供給部分４と筒部６ａを圧接せしめるべくネジ部６ｂを発熱体１０の金属１を貫通する穴を通し、絶縁部材７の穴部７ａにネジ部６ｂを貫通させた状態で、平ワッシャ８を介しナット９で締め付けた構造である。また、電極６のネジ部６ｂの反対側にネジ部６ｂと同軸上に、円柱形状のピン１２もしくはネジ１３を設けているものである。この様にすることにより、電源コード等を溶接、半田付け、またネジによる固定を容易に行える構造とすることができる。
【００２１】
【発明の効果】
以上、本発明はこのような構成としたことにより、電極の取り付け構成が常に導電体を基板に押し付ける応力となり、電極に外力が加わっても導電体が基板から剥離断線し発熱不能になることがない。
【００２５】
さらに、電極のネジ部と反対側筒部にネジ部と同軸上に、円柱形状のピンもしくはネジを設けることにより、リード線等を溶接、半田付け、またネジによる固定が容易に行えるようになるものである。
