【発明の詳細な説明】 センサのためのシール部材 背景技術 本発明は請求項１の上位概念によるガスセンサのセンサ部材のためのシールか ら出発する。このようなシールは例えばＤＥ １９５ ３２ ０９０から公知で あり，この公知のシールにおいては，センサ部材はケーシングの縦孔内で，少な くとも２つのシール体とこれらのシール体の間に配置されている変形可能な付加 シールとによって取り付けられている。両方のシール体はケイ酸アルミニウムマ グネシウム又はステアタイトから成り，これらのシール体の間に取り付けられて いるシール体はホウ素窒化物の六方晶系同素体から成っている。 発明の利点 請求項１の特徴を具備した本発明によるシールは，シールがガス密であるとと もに，液体特に燃料に対して不透過性であり，しかも極めて大きな耐熱性を有し ているという利点を備えている。このことは，ホウ素窒化物（ＢＮ）の六方晶系 同素体と少なくとも１種の酸化物セラミック成分との混合物によって達成される 。更に種々の化学的組成のシール部材からシールを構成する代わりに，酸化物セ ラミック成分とＢＮとの混 合物を使用することによって，シールの取り扱い及び組み立てが簡単になる。 従属請求項に記載した手段によって，本発明によるシールを有利に構成し，か つ発展させることが可能である。 特に有利には，ほぼ化学式３ＭｇＯ・４ＳｉＯ2・Ｈ2Ｏのステアタイト，換言 すれば凍石の燃焼生成物がＢＮの六方晶系同素体と混合させて使用される。これ によって特に大きな温度安定性が保証される。その六方晶系同素体が，極めて細 粒の，かつその等構造体であるグラファイトと同じように良好に変形可能な化合 物であるホウ素窒化物を使用することによって，シール性が著しく改善される。 特に有利な構成では，シール部材内のＢＮ分は５〜１０重量％である。シール の組み立ての際の良好な取り扱い性は，ステアタイト/ＢＮのシール体があらか じめ焼結された状態で使用され，組み立ての際の力の作用によって変形せしめら れて，シール体の材料がセンサ部材及びケーシングに圧着され，これによってセ ンサ部材がケーシング内でガス密に保持されるようにすると，達成される。 図面 本発明の１実施例は図面に示されており，以下において詳細に説明する。図１ は本発明によるシール装置を有するガスセンサの断面を示す。 実施例 ただ１つの図面はガスセンサ１０，例えば電気化学的酸素センサ，を示し，こ れは金属製のケーシング１２を有しており，このケーシングは，図示していない 測定ガス管内への取り付けのための固定手段としてねじ山１３を有している。ケ ーシング１２は肩形の環状面１６を備えた縦孔１５を有している。肩形の環状面 １６上には例えば金属製のシールリング１８があり，このシールリング上に測定 ガス側のセラミック成形部分２１が載着されている。この測定ガス側のセラミッ ク成形部分２１は縦孔１５の方向に延びている測定ガス側の貫通孔２２を有して いる。測定ガス側のセラミック成形部分２１から間隔をおいて，更に縦孔１５内 に接続側のセラミック成形部分２３が配置されている。この接続側のセラミック 成形部分２３はやはり縦孔１５の方向に延びている中央の接続側の貫通孔２４を 有している。測定ガス側のセラミック成形部分２１の測定ガス側の貫通孔２２と 接続側のセラミック成形部分２３の接続側の貫通孔２４とは互いに一直線に並ん で延びている。 貫通孔２２，２４内には，測定ガス側の端区分２８及び接続側の端区分２９を 備えた小板形のセンサ部材２７がある。 センサ部材２７の測定ガス側の端区分２８はケーシング１２から突出していて ，保護管３１によって取り 囲まれており，この保護管はケーシング１２に固定されている。保護管３１は測 定されるガスのための出入開口３２を有している。接続側の端区分２９は接続接 点３４を有しており，この接続接点はやはりケーシング１２から突出している。 接続接点３４は接続ケーブルを備えた図示していない接点プラグと接点接触せし められる。ケーシング１２から突出している接続側の端区分２９は，図示してい ない包囲体によって取り囲まれており，この包囲体は端区分２９を周囲の影響に 対して保護する。 測定ガス側のセラミック成形部分２１と接続側のセラミック成形部分２３との 間にはシール３７があり，これはＢＮ/ステアタイトの混合物から成っている。 ホウ素窒化物は六方晶系同素体として存在し，例えばシール部材３７に対して１ ０重量％の割合を有している。このシール部材３７上を接続側のセラミック成形 部分２３が加圧している。接続側のセラミック成形部分２３のこの加圧力は金属 スリーブ４０によって作用せしめられる。金属スリーブ４０は例えば一様に分配 された複数の，内方に向いたつめ４１を有しており，これらのつめはケーシング １２に形成されたノッチ４２内に係合している。しかし金属スリーブ４０をケー シング１２と溶接しておくことも考えられる。ＢＮ/ステアタイト混合物から成 るシール部材３７は，ケーシング１２の縦孔１５内に取り付ける前に，例えば５ ００℃の低い温度で焼結されて，あらかじめリングに成形される。このようにし て形成されたリング形のシール部材３７は，この実施例におけるように，センサ 部材２７を既に有している縦孔１５内にはめ込まれる。シール３７上に次いで接 続側のセラミック成形部分２３が配置される。次いで接続側のセラミック成形部 分上に金属スリーブ４０が載着される。次いで例えばプランジャによって金属ス リーブ４０上に力が作用せしめられ，この力は接続側のセラミック成形部分２３ を介してシール部材３７に作用する。この場合シール部材３７のあらかじめ製作 されたリングは変形せしめられ，シール部材３７の材料がセンサ部材２７及びケ ーシング１２に圧着される。 シール作用は大体において六方晶系のＢＮ−同素体の割合によって決定される ことが分かった。 広い温度範囲にわたってガス及び燃料に対するシール性を達成するために重要 なことは，シール部材３７に常に金属スリーブ４０からの力が作用していること である。ホウ素窒化物の熱膨張係数（約４．４×１０-6Ｋ-1）よりもステアタイ トの熱膨張係数（８．８×１０-6Ｋ-1）が大きいことに基づいて，両方の成分を 相応に混合することによって，温度が高い場合でも金属スリーブ４０からの加圧 力をシール部材３７に作用させることができる。 本発明によるシール部材３７は金属製のケーシング 内のプレーナ型のセンサ部材のシールに限定されるものではない。このようなシ ール部材３７をいわゆるフィンガセンサのシールに使用することも当然考えられ る。この場合には，シール部材３７のためのあらかじめ製作されたリングの構造 を，縦孔及びケーシングとフィンガ形のセンサ部材との接触面の幾何形状に適合 させるだけでよい。BACKGROUND OF THE INVENTION The invention starts with a seal for a sensor element of a gas sensor according to the preamble of claim 1. Such a seal is known, for example, from DE 195 32 090, in which a sensor element is arranged in a longitudinal bore of a housing and at least two seals are arranged between these seals. Mounted with possible additional seals. Both seals are made of aluminum magnesium silicate or steatite, and the seal between these seals is made of hexagonal boron nitride allotrope. ADVANTAGES OF THE INVENTION The seal according to the invention with the features of claim 1 has the advantage that the seal is gas-tight, impermeable to liquids, in particular to fuel, and has a very high heat resistance. Have. This is achieved by a mixture of a hexagonal allotrope of boron nitride (BN) and at least one oxide ceramic component. Further, the use of a mixture of oxide ceramic component and BN, instead of constructing the seal from seal members of various chemical compositions, simplifies the handling and assembly of the seal. By means of the dependent claims, it is possible to advantageously design and develop the seal according to the invention. Particularly advantageously used in approximately chemical formula 3MgO · 4SiO 2 · H 2 O steatite, combustion products frozen stones in other words mixed with hexagonal allotrope of BN. This ensures a particularly high temperature stability. The use of boron nitride, a compound whose hexagonal allotrope is extremely fine-grained and as easily deformable as its isostructural graphite, significantly improves the sealability. In a particularly advantageous configuration, the BN content in the sealing element is between 5 and 10% by weight. The good handleability during the assembly of the seal is due to the fact that the steatite / BN seal body is used in a pre-sintered state and is deformed by the action of the assembly force, and the material of the seal body is used as the sensor member This is achieved when the sensor element is pressed against the housing so that the sensor element is kept gas-tight within the housing. Drawings One embodiment of the present invention is shown in the drawings and will be described in detail below. FIG. 1 shows a cross section of a gas sensor having a sealing device according to the present invention. DESCRIPTION OF THE PREFERRED EMBODIMENTS The sole FIGURE shows a gas sensor 10, for example an electrochemical oxygen sensor, which has a metal housing 12, which is provided for mounting in a measuring gas pipe, not shown. It has a thread 13 as a fixing means. The casing 12 has a longitudinal hole 15 with a shoulder-shaped annular surface 16. On the shoulder-shaped annular surface 16 there is, for example, a sealing ring 18 made of metal, on which a ceramic molding 21 on the measuring gas side is mounted. The ceramic molded part 21 on the measurement gas side has a through hole 22 on the measurement gas side extending in the direction of the vertical hole 15. A ceramic molding portion 23 on the connection side is arranged in the vertical hole 15 at a distance from the ceramic molding portion 21 on the measurement gas side. The connection-side ceramic molded part 23 has a central connection-side through-hole 24 that also extends in the direction of the vertical hole 15. The through hole 22 on the measurement gas side of the ceramic molding portion 21 on the measurement gas side and the through hole 24 on the connection side of the ceramic molding portion 23 on the connection side extend in line with each other. A small plate-shaped sensor member 27 having an end section 28 on the measurement gas side and an end section 29 on the connection side is provided in the through holes 22 and 24. The end section 28 of the sensor element 27 on the measuring gas side protrudes from the housing 12 and is surrounded by a protective tube 31, which is fixed to the housing 12. The protective tube 31 has an access opening 32 for the gas to be measured. The connection-side end section 29 has a connection contact 34, which also projects from the housing 12. The connection contact 34 is brought into contact with a contact plug (not shown) provided with a connection cable. The connection-side end section 29 projecting from the housing 12 is surrounded by an enclosure (not shown), which protects the end section 29 against ambient influences. Between the ceramic molding part 21 on the measuring gas side and the ceramic molding part 23 on the connection side there is a seal 37, which consists of a mixture of BN / steatite. Boron nitride exists as a hexagonal allotrope, and has a ratio of, for example, 10% by weight to the sealing member 37. The ceramic molding portion 23 on the connection side presses the seal member 37. This pressing force of the ceramic part 23 on the connection side is exerted by the metal sleeve 40. The metal sleeve 40 has, for example, a plurality of evenly distributed inwardly directed pawls 41 which engage in notches 42 formed in the casing 12. However, it is also conceivable that the metal sleeve 40 is welded to the casing 12. The seal member 37 made of the BN / steatite mixture is sintered at a low temperature of, for example, 500 ° C. before being mounted in the vertical hole 15 of the casing 12 and is formed into a ring in advance. The ring-shaped sealing member 37 thus formed is fitted into the vertical hole 15 already having the sensor member 27 as in this embodiment. The connection-side ceramic molded part 23 is then arranged on the seal 37. Next, the metal sleeve 40 is mounted on the ceramic molding portion on the connection side. A force is then exerted on the metal sleeve 40 by, for example, a plunger, which acts on the sealing member 37 via the ceramic molding 23 on the connection side. In this case, the previously manufactured ring of the sealing member 37 is deformed, and the material of the sealing member 37 is pressed against the sensor member 27 and the casing 12. It has been found that the sealing action is largely determined by the proportion of the hexagonal BN-allotrope. What is important for achieving gas and fuel sealing over a wide temperature range is that a force from the metal sleeve 40 always acts on the sealing member 37. Based on the fact that steatite has a larger thermal expansion coefficient (8.8 × 10 −6 K −1 ) than that of boron nitride (about 4.4 × 10 −6 K −1 ), both components Can be applied to the sealing member 37 even when the temperature is high. The sealing member 37 according to the present invention is not limited to sealing a planar sensor member in a metal casing. It is naturally conceivable to use such a sealing member 37 for sealing a so-called finger sensor. In this case, it is only necessary to adapt the structure of the prefabricated ring for the sealing element 37 to the geometry of the vertical bore and the contact surface between the casing and the finger-shaped sensor element.
