Description
本考案は、電気機器に信号や電源を供給する目的に使用される気密端子に関する。 The present invention relates to an airtight terminal used for the purpose of supplying a signal or power to an electrical device.
電子・電気機器に信号や電源を供給する目的で、ハウジング等に設けた通孔の周囲に沿って電気溶接などで密閉できるように構成した気密端子がある。例えば、空調機器や冷凍機などに使用されるコンプレッサには、モータユニットのハウジングに密閉式に固定した気密端子を介して電源からハウジング内のモータに電力供給されている。ところが、コンプレッサは内部に回転部分のモータを有するので、使用中の摺動磨耗によって導電性微粉末が発生することが避けられない。もし、この導電性微粉末が気密端子の金属ステムと電極棒とを電気的に絶縁するガラスなどからなる絶縁材の表面に付着すると、金属ステムと電極棒との間の絶縁抵抗が次第に低下し、甚だしい場合は両者間が短絡して過大な電流が流れ、その発熱によって絶縁材が溶融して、冷媒内圧によって電極棒が外部に抜けて飛び出してくる危険があった。 For the purpose of supplying signals and power to electronic and electrical equipment, there is an airtight terminal configured so that it can be hermetically sealed by electric welding or the like along a periphery of a through hole provided in a housing or the like. For example, a compressor used in an air conditioner, a refrigerator, or the like is supplied with electric power from a power source to a motor in the housing via an airtight terminal fixed in a sealed manner to the motor unit housing. However, since the compressor has a motor in the rotating portion, it is inevitable that conductive fine powder is generated due to sliding wear during use. If this conductive fine powder adheres to the surface of an insulating material made of glass or the like that electrically insulates the metal stem of the hermetic terminal and the electrode rod, the insulation resistance between the metal stem and the electrode rod gradually decreases. In a severe case, there was a risk that an excessive current would flow due to a short circuit between the two, the insulating material would melt due to the heat generation, and the electrode rod would come out and jump out due to the internal pressure of the refrigerant.
こうした事故を防止するために、従来から気密端子の電極棒にセラミック材からなる絶縁スリーブを挿着して、金属ステムと電極棒との沿面距離を大きく取れるようにし、金属ステムと電極棒との間の絶縁信頼性を向上させた気密端子がある。例えば、特許文献１に記載された気密端子のように、断面形状が漏斗形を有するセラミック製の絶縁スリーブを、金属ステムの小筒部に貫通させた電極棒に挿通し、さらに絶縁スリーブの小径端部を金属ステムの小筒部孔内に挿入させて金属ステム内底部に当接させて、この絶縁スリーブと小筒部孔内の絶縁ガラス材と共働して金属ステムを封止したものがある。しかしながら、セラミック製絶縁スリーブは表面に微細な凹凸があり、導電性微粉末が表面に付着しやすいため、短絡不良を完全に無くすことが出来なかった。また、部品単価が高価なセラミック部材は、一般用途向けの汎用気密端子には経済的に使い難いと言う欠点もあった。
In order to prevent such an accident, conventionally, an insulating sleeve made of a ceramic material is attached to the electrode rod of the hermetic terminal so that the creepage distance between the metal stem and the electrode rod can be increased. There are hermetic terminals with improved insulation reliability. For example, like a hermetic terminal described in
本考案の目的は、上記課題を解消するため提案するものであり、より経済的かつ簡便に気密端子の耐トラッキング特性を向上できる気密端子の構成を提案することにある。 An object of the present invention is to propose the structure of an airtight terminal capable of improving the tracking resistance characteristics of the airtight terminal more economically and easily.
本考案の気密端子は、金属外環と、この金属外環に設けた貫通孔に挿通したリードと、このリードと金属外環とを気密に封着した封止ガラスと、少なくとも片側リードに装着した耐熱性プラスチックからなる絶縁鞘体とを備え、絶縁鞘体の一端を封止ガラスおよび金属外環に耐熱性封止樹脂で固着したことを特徴とする気密端子が提供される。絶縁鞘体は、概ね２００℃以上の耐熱性プラスチックであればよく、従来のセラミック・スリーブに比べ安価な材料構成となる。この絶縁鞘体は、完成後の気密端子に常温ないし低温加熱でオプションとして簡便に取り付けることができ、従来のセラミック・スリーブの様に高温炉でガラス封着させる必要が無く、作業を容易にして加工プロセスの効率化と組み立てコスト低減を実現する。 The hermetic terminal of the present invention is attached to a metal outer ring, a lead inserted through a through hole provided in the metal outer ring, a sealing glass in which the lead and the metal outer ring are hermetically sealed, and at least one lead. There is provided an airtight terminal comprising an insulating sheath body made of a heat-resistant plastic, wherein one end of the insulating sheath body is fixed to a sealing glass and a metal outer ring with a heat-resistant sealing resin. The insulating sheath body may be a heat-resistant plastic of approximately 200 ° C. or higher, and has a material structure that is less expensive than a conventional ceramic sleeve. This insulation sheath can be easily attached to the completed airtight terminal as an option at room temperature or low temperature heating, and does not require glass sealing in a high temperature furnace like conventional ceramic sleeves, making it easy to work. Realize more efficient machining process and lower assembly cost.
本考案の気密端子は、従来のセラミック・スリーブ挿着端子に比べ安価な材料構成となる。本考案の絶縁鞘体は、封止が完成した気密端子に常温ないし低温加熱で簡便に取り付けができ、従来のセラミック・スリーブの様に高温炉でガラス封着させる必要が無ない。従って、材料費の削減ができ、作業の簡素化と効率化に寄与する他、既製品の気密端子に後付可能なオプション形態としても利用できる。 The hermetic terminal of the present invention has an inexpensive material structure compared to a conventional ceramic sleeve insertion terminal. The insulating sheath body of the present invention can be easily attached to a hermetic terminal which has been sealed at normal or low temperature heating, and there is no need for glass sealing in a high temperature furnace unlike a conventional ceramic sleeve. Therefore, the material cost can be reduced, contributing to the simplification and efficiency of the work, and can also be used as an optional form that can be retrofitted to a ready-made airtight terminal.

There is provided an airtight terminal comprising an insulating sheath body made of a heat-resistant plastic, wherein one end of the insulating sheath body is fixed to a sealing glass and a metal outer ring with a heat-resistant sealing resin. The insulating sheath body is preferably a plastic material having a heat resistance of approximately 200 ° C. or higher. For example, PBI (PolyBenzImidazol), PEK (PolyEtherKetone), PPS (PolyPhenyleneSulfide), PTFE (PolyTertraFluoroEthyene), PEEK (PolyEtherEtherKetone), PEKK (PolyEtherKetoneKetone), PEEKK (PolyEtherEtherKetoneKetone), plastic tubing selected from the group of PEKEKK (PolyEtherKetoneEtherKetoneKetone) Is preferred.
