Description

本発明は、発火装薬（pyromechanical propellant charge）により駆動される切断具によって切断部で切断されることができるように形成されている導電性の電流伝導体レールが内部に配置されたハウジングを備えていて、電流伝導体レールが、その複数の端片（end pieces）に、それぞれ、導電部材を接続するための固定手段（fastening facility）を有している発火機械式の切断装置（pyromechanical disconnecting device）に関するものである。   The present invention includes a housing having a conductive current conductor rail formed therein that is configured to be cut at a cutting portion by a cutting tool driven by a pyromechanical propellant charge. A pyromechanical disconnecting device, wherein the current conductor rail has a fastening facility for connecting a conductive member to each of its end pieces, respectively. ).

この種の発火機械式の切断装置は、特許文献１に記載されているが、ハウジング内に直線状に配置された導電性の電流伝導体レール（導電体）を備えている。
独国特許出願公開第１９７１２３８７号明細書 This kind of ignition mechanical cutting device is described in Patent Document 1, but includes a conductive current conductor rail (conductor) arranged linearly in a housing.
German Patent Application Publication No. 1971387

このような導電体の担持手法の欠点は、次のとおりである。すなわち、導電体は、直線状に担持され、必要なねじにより、例えば自動車のバッテリに接続されているので、車両の運転時に生じる振動、衝撃、温度変化等が電流伝導体レールの望ましくない変形及びねじれを生じさせる結果となる。そして、これは、極端な場合には、電流伝導体レールの破損を生じさせ、これにより車両における電流の供給が中断されるといった望ましくない結果が生じる。   The disadvantages of such a conductor loading technique are as follows. That is, the conductor is supported in a straight line and is connected to, for example, an automobile battery by a necessary screw, so that vibration, impact, temperature change, etc. that occur during driving of the vehicle may cause undesirable deformation of the current conductor rail and This results in twisting. This, in extreme cases, can result in damage to the current conductor rail, which can lead to undesirable consequences such as interrupting the current supply in the vehicle.

本発明の目的は、請求項１の「おいて書き部」に記載された発火機械式の切断装置を、強い応力が生じた場合でも電流伝導体レールの破損を生じさせず、切断部が規定された導電体断面を有するようにさらに改良することである。   An object of the present invention is to provide an ignition-mechanical cutting device according to claim 1 that does not cause breakage of the current conductor rail even when strong stress is generated, and the cutting portion is defined. Further improvement is made to have an improved conductor cross section.

本発明によれば、この目的は、電流伝導体レールの２つの端片を切断部の面（plane of the disconnecting point）に対して直角に配置し、かつ、切断部を、電流伝導体断面がテーパ状（tapering）になるように形成することにより達成される。   According to the invention, the object is to place the two end pieces of the current conductor rail at right angles to the plane of the disconnecting point, and the cutting section has a current conductor cross section. This is achieved by forming the taper.

本発明の有利な形態においては、導電体断面のテーパ状の部分は、電流伝導体レールの全幅にわたって形成されている。   In an advantageous form of the invention, the tapered section of the conductor cross section is formed over the entire width of the current conductor rail.

切断部の面に対して直角に形成された端片の配置構造は、それぞれの場合において、電流伝導体レールの２つの直角曲がり部によって好ましく実現される。この曲がり部は、電流伝導体レールの２つの異なる部位に形成されている。   The arrangement of the end pieces formed perpendicular to the plane of the cut is preferably realized in each case by two right-angle bends of the current conductor rail. This bend is formed at two different locations of the current conductor rail.

切断部は、好ましく、電流伝導体レールの長手方向と交差するように配置された残存電流伝導体レール（remaining current conductor rail）への２つの移行部（transition）を伴って、電流伝導体レール上に四角形部を形成している。ここで、ある実施態様においては、移行部は残存電流伝導体レール内で終わるように対角線方向に伸びている。   The cut is preferably on the current conductor rail with two transitions to a remaining current conductor rail arranged so as to intersect the longitudinal direction of the current conductor rail. A quadrangular portion is formed. Here, in some embodiments, the transition extends diagonally to end within the residual current conductor rail.

あるいは、一方の移行部が、テーパ状の部分において片側に形成されたノッチ（notch）を有し、他方の移行部が曲がり部として形成されていてもよい。かくして、切断具は、ノッチで切断部を切断して、この後曲がり部でテーパ状の部分を曲げることができる。   Alternatively, one transition portion may have a notch formed on one side in a tapered portion, and the other transition portion may be formed as a bent portion. Thus, the cutting tool can cut the cut portion with the notch and thereafter bend the tapered portion at the bent portion.

これは、曲がり部が、切断具に背向している移行部の側に内側ノッチを好ましく有する場合には、より容易に実現される。   This is more easily achieved if the bend preferably has an inner notch on the side of the transition facing away from the cutting tool.

この発火機械式の切断装置は、事故に際しての自動車のバッテリの電気的な遮断に好ましく用いられる。   This ignition-mechanical cutting device is preferably used for electrical disconnection of an automobile battery in the event of an accident.

以下、添付の各図面を用いて、本発明をより詳しく説明する。   Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

図１は、ハウジング下部３とハウジング上部４とからなるハウジング２内に配置された電流伝導体レール１を示している。図１中には、さらに、切断具５が示されている。この切断具５は、適当な手段によって加速され、その運動エネルギにより電流伝導体レール１を切断する。   FIG. 1 shows a current conductor rail 1 arranged in a housing 2 consisting of a housing lower part 3 and a housing upper part 4. In FIG. 1, a cutting tool 5 is further shown. The cutting tool 5 is accelerated by an appropriate means, and cuts the current conductor rail 1 by its kinetic energy.

図２は、電流伝導体レール１の全体を示している。切断部７は、電流伝導体レール１の長手方向と交差するように配置された残存電流伝導体レール９への２つの移行部１１を伴って、電流伝導体レール１上に四角形部を形成している。複数の端片１１には（sic：原文）、それぞれ、固定手段６（fastening facility）が設けられている。なお、ここでは、固定手段は留め穴（fastening hole）である。これらの２つの端片１４は、切断部７の面に対して直角に配置されている。この切断部７の面に対する直角配置は、それぞれ、２つの異なる部位１６、１７における電流伝導体レール１の２つの直角曲がりによって実現される。これは、切断部７上の力を低減し、これにより部品上の機械的応力をかなり低減するので有利である。   FIG. 2 shows the entire current conductor rail 1. The cutting part 7 forms a square part on the current conductor rail 1 with two transitions 11 to the remaining current conductor rail 9 arranged to intersect the longitudinal direction of the current conductor rail 1. ing. Each of the plurality of end pieces 11 (sic: original text) is provided with a fixing means 6 (fastening facility). Here, the fixing means is a fastening hole. These two end pieces 14 are arranged at right angles to the surface of the cutting portion 7. This right-angled arrangement with respect to the plane of the cut 7 is realized by two right-angle bends of the current conductor rail 1 at two different sites 16, 17 respectively. This is advantageous because it reduces the force on the cut 7 and thereby significantly reduces the mechanical stress on the part.

図３は、切断部７の領域における、電流伝導体レール１の断面を示している。切断部７で、導電体断面８は、残存電流伝導体レール９に対してテーパ状となっている。このテーパ状の部分（tapering）の長さは参照番号１０で示されている。切断部７の縁部（edge）は、それぞれ、移行部１１を経て、残存電流伝導体レール９につながっている。図３に示す実施の形態においては、これらの移行部は、対角線方向に伸びて、残存電流伝導体レール７（sic：原文）につながっている。   FIG. 3 shows a cross section of the current conductor rail 1 in the region of the cutting part 7. At the cutting portion 7, the conductor cross section 8 is tapered with respect to the residual current conductor rail 9. The length of this tapered portion is indicated by reference numeral 10. The edges of the cutting part 7 are each connected to the residual current conductor rail 9 via the transition part 11. In the embodiment shown in FIG. 3, these transitions extend in a diagonal direction and are connected to a residual current conductor rail 7 (sic: original).

図４はノッチ１２が追加されたものを示している。   FIG. 4 shows a notch 12 added.

図５は、ノッチ１２を示すとともに、反対側の移行部として曲がった移行部１１が追加されたものを示し、これにより曲がり部１５（湾曲部）が形成されている。   FIG. 5 shows the notch 12 and the addition of the bent transition portion 11 as the opposite transition portion, whereby a bent portion 15 (curved portion) is formed.

図６に示す例では、切断具５と背向する側において移行部１１の曲がり部１５に内側ノッチ１３（inward notch）が形成されている。この内側ノッチ１３は、切断過程をかなり容易化する。   In the example shown in FIG. 6, an inner notch 13 (inward notch) is formed in the bent portion 15 of the transition portion 11 on the side facing away from the cutting tool 5. This inner notch 13 considerably facilitates the cutting process.

この切断装置は、事故に際しての自動車のバッテリの電気的な遮断に好ましく用いられる。   This cutting device is preferably used for electrical disconnection of an automobile battery in the event of an accident.
