一般に従来の密封ターミナルとしては実公昭56−46542号公報に記載さ れたようなものがあった。この公報に記載されたものは、ターミナル(端子)、 密着ガラス、金属外環から構成された密封ターミナルであった。 Generally, there is a conventional sealed terminal as described in Japanese Utility Model Publication No. 56-46542. What was described in this publication was a sealed terminal composed of a terminal, a contact glass, and a metal outer ring.

【考案が解決しようとする課題】[Problems to be solved by the device]

このように構成された密封ターミナルでは、誘電率が8程度のガラス(密封ガ ラス9でターミナルと金属外環とを絶縁しているが、このターミナルには圧縮機 の摺動部の磨耗粉が寄りつきやすい問題があった。また、圧縮機のモータ焼けな どの異常が生じると、このガラスにカーボンが付着して絶縁性が低下しガラスの 溶融等に至るなどの問題点があった。 In the sealed terminal configured in this way, the glass having a dielectric constant of about 8 is used to insulate the terminal and the metal outer ring with the sealed glass 9. In addition, there was a problem that when the compressor motor burned, an abnormality such as a motor burn occurred and carbon adhered to the glass to lower its insulating property, causing the glass to melt.

【0005】 このような問題点に対して図3(密封ターミナルの断面図)に示すようなもの を考えた。図3において、1は金属外環であり、密閉容器(密閉型圧縮機)の貫 通孔に内側から外側に向かって圧縮機の内部を密閉できるように嵌められている 。For such a problem, the one shown in FIG. 3 (cross-sectional view of the sealed terminal) was considered. In FIG. 3, reference numeral 1 denotes a metal outer ring, which is fitted in a through hole of a closed container (closed type compressor) so as to be able to close the inside of the compressor from the inside to the outside.

【0006】 2、3はターミナルであり、密閉容器の外側から内側へ電力を供給する。4は 密封ガラスであり、ターミナル2、3と金属外環1とを絶縁している。6はカバ ー(PET:ポリエチレンテレフタレート)であり、ターミナル2、3の密閉容 器の内側から嵌め、外周のツバ6でカバー5が斜めにはいるのを防止している。 また、このカバー5の形状はターミナル2、3にぴったり、しっくり納まるよう な形に構成されている。Reference numerals 2 and 3 denote terminals that supply electric power from the outside to the inside of the closed container. Reference numeral 4 denotes a hermetically sealed glass, which insulates the terminals 2 and 3 from the metal outer ring 1. Reference numeral 6 denotes a cover (PET: polyethylene terephthalate), which is fitted from the inside of the sealed container of the terminals 2 and 3, and the cover 5 at the outer periphery prevents the cover 5 from being obliquely inserted. Further, the shape of the cover 5 is configured so as to fit the terminals 2 and 3 and fit snugly.

【0007】 この図3に示すカバー5を用いた場合、冷媒や油がターミナル2、3とカバー 5との間に入り込み、低温で油が固まりターミナル部をシールすると、後に温度 が上昇し液状態で油にとけ込んでいた冷媒がガス化すると、カバーが膨れ、最悪 時にはその膨張でターミナル2、3が動くことがあった。When the cover 5 shown in FIG. 3 is used, the refrigerant or oil enters between the terminals 2 and 3 and the cover 5, and the oil solidifies at a low temperature to seal the terminal portion, and then the temperature rises to a liquid state. When the refrigerant that had melted in the oil was gasified, the cover swelled, and at worst, the expansion caused the terminals 2 and 3 to move.

【0008】 尚、7はクラスタ、8はリセプタクル、9は引出線であり、ターミナル2に与 えられた電力はリセプタクル8、引出線9を介して電動機へ供給される。In addition, 7 is a cluster, 8 is a receptacle, and 9 is a lead wire, and the electric power applied to the terminal 2 is supplied to the electric motor through the receptacle 8 and the lead wire 9.

【0009】 本考案はこのような問題点に対し、膨張冷媒の逃がし構造を備えたカバーを提 供するものである。The present invention provides a cover having a structure for allowing the expansion refrigerant to escape, in order to solve such problems.

【0010】[0010]

【課題を解決するための手段】[Means for Solving the Problems]

本考案のターミナルカバーは、密閉容器の内側から外側へ貫通して設けられる 密封ターミナルにおいて、この密封ターミナルに密閉容器の内側と外側とを電気 的につなぐ複数のターミナルと、このターミナルの密閉容器の内側に嵌められる カバーとを備えると共に、このカバーはターミナルの根本付近を包みこのカバー とターミナル間に生じるガスをカバーの縁から逃がす構成を備えたものである。 The terminal cover of the present invention is a sealed terminal that is provided to penetrate from the inside to the outside of a sealed container. In the sealed terminal, a plurality of terminals that electrically connect the inside and outside of the sealed container to the sealed terminal and In addition to having a cover fitted inside, the cover has a structure that wraps around the base of the terminal and allows gas generated between the cover and the terminal to escape from the edge of the cover.

【0011】[0011]

【作用】[Action]

このように構成されたターミナルカバーを用いることによって、冷媒がガス化 した際に、その圧力でカバーの外周が膨れガス化した冷媒を逃がすことができる ものである。 By using the terminal cover configured as described above, when the refrigerant is gasified, the pressure causes the outer circumference of the cover to swell and the gasified refrigerant can escape.

【0012】[0012]

【実施例】【Example】

以下本考案の実施例を図1、図2に基図いて説明する。尚、図3に示した構成 と同一のもは同一符号を付して説明を省略する。カバー10は図3に示すカバー 5のツバ6を取り除いた構成である。図2はカバー10の上面図であり、外周部 11にツバ6がない。他の構造は図3に示したカバー5と同じである。 An embodiment of the present invention will be described below with reference to FIGS. The same components as those shown in FIG. 3 are designated by the same reference numerals and the description thereof will be omitted. The cover 10 has a structure in which the brim 6 of the cover 5 shown in FIG. 3 is removed. FIG. 2 is a top view of the cover 10, in which the outer peripheral portion 11 has no brim 6. The other structure is the same as that of the cover 5 shown in FIG.

【0013】 このように構成することによって、カバー10とターミナルとの間で冷媒がガ ス化しても、カバー10の外周部11がめくれてガスを逃がすことができる。With this configuration, even if the refrigerant becomes gas between the cover 10 and the terminal, the outer peripheral portion 11 of the cover 10 is turned over to allow the gas to escape.

【0014】[0014]

【考案の効果】[Effect of device]

本考案のターミナルカバーは、密閉容器の内側から外側へ貫通して設けられる 密封ターミナルにおいて、この密封ターミナルに密閉容器の内側と外側とを電気 的につなぐ複数のターミナルと、このターミナルの密閉容器の内側に嵌められる カバーとを備えると共に、このカバーはターミナルの根本付近を包みこのカバー とターミナル間に生じるガスをカバーの縁から逃がす構成を備えたので、カバー とターミナルとの間にガスが発生しても、カバーの外周部からガスを逃がすこと ができ、ターミナルの押し上げなどの問題発生がなくなるものである。 The terminal cover of the present invention is a sealed terminal that is provided to penetrate from the inside to the outside of a sealed container. In the sealed terminal, a plurality of terminals that electrically connect the inside and outside of the sealed container to the sealed terminal and In addition to having a cover that fits inside, this cover has a structure that wraps around the base of the terminal and allows gas generated between this cover and the terminal to escape from the edge of the cover, so that gas is generated between the cover and the terminal. Even so, the gas can escape from the outer periphery of the cover, and problems such as pushing up the terminal will not occur.
