Abstract

A casing comprises two half-shells (1,2), each containing a ferrite element for noise suppressing. In the clamped state the casing has a through aperture in each side wall (5) for an electric cable. The two ferrite elements have each a semi-cylindrical groove so that, with the casing closed, an enclosed, cylindrical passage for the electric cable is formed. Each half-shell contains a fastener for the ferrite element.

Description

Die Erfindung geht aus von einer Einrichtung zum Absorbieren des elektrischen Rauschens. Es ist seit langem bekannt, daß man mit Hilfe von Elementen aus ferromagnetischem Material das elektrische Rauschen auf der Leitung reduzieren kann (US-PS 3462715).The invention is based on a device for absorbing electrical noise. It has long been known that one can reduce the electrical noise on the line by means of elements made of ferromagnetic material (US-PS 3462715).

Weiterhin ist eine Einrichtung zum Absorbieren des elektrischen Rauschens bekannt (US-A-5,506,909), bei der in jeder Gehäusehalbschale an der Kante der Längsseitenwand ein flexibler Streifen angeformt ist, ebenso wie an der Kante der Stirnwand. Die Streifen sind so flexibel, dass sie gegenüber den Gehäusewänden umgebogen werden können. Wenn die Magnete in die Gehäusehälften eingesetzt werden, liegen diese flexiblen Streifen an den Seiten- bzw. Stirnflächen der Magnete an.Furthermore, a device for absorbing the electrical noise is known (US-A-5,506,909), in which in each housing half shell at the edge of the longitudinal side wall, a flexible strip is formed, as well as at the edge of the end wall. The strips are so flexible that they can be bent over the housing walls. When the magnets are inserted into the housing halves, these flexible strips abut the side or end faces of the magnets.

Es ist bereits eine solche Einrichtung bekannt (EP-A-452992), bei der zwei Halbelemente aus ferromagnetischem Material in einem geteilten Gehäuse untergebracht werden, dessen Böden elastische Vorspannmittel aufweisen, die die beiden magnetischen Elemente aufeinander zu pressen.There is already known such a device (EP-A-452992) in which two half-elements of ferromagnetic material are housed in a split housing, the bottoms of which have elastic biasing means which press the two magnetic elements towards one another.

Der Erfindung liegt die Aufgabe zugrunde, eine einfach aufgebaute und sicher wirkende Einrichtung zum Absorbieren des elektrischen Rauschens zu schaffen.The invention has for its object to provide a simply constructed and safe-acting device for absorbing the electrical noise.

Zur Lösung dieser Aufgabe schlägt die Erfindung eine Einrichtung mit den Merkmalen des Anspruchs 1 vor. Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche, deren Wortlaut ebenso wie der Wortlaut der Zusammenfassung durch Bezugnahme zum Inhalt der Beschreibung gemacht wird.To solve this problem, the invention proposes a device with the features of claim 1. Further developments of the invention are the subject matter of the dependent claims, the wording of which as well as the wording of the abstract is incorporated by reference into the content of the description.

Die Einrichtung wird so benutzt, daß die beiden Elemente aus dem ein Rauschen verhindernden Material, die im folgenden Ferritelemente genannt werden, in die Gehäuseteilschalen eingesetzt werden und dann das Gehäuse um das elektrische Kabel herum angeordnet wird. In Weiterbildung der Erfindung kann vorgesehen sein, daß die Einrichtung zum Festlegen der Ferritelemente an mindestens einer stirnseitigen Eckkante des Ferritelements angreift, die senkrecht zu der Grenzfläche zwischen den beiden Ferritelementen verläuft. Die Festlegeeinrichtung greift daher in einer solchen Weise an, daß keine Kräfte entstehen, die die Ferritelemente in Richtung auf die Trennfläche anpressen, so daß diese auch nicht in umgekehrter Richtung nachgeben können.The device is used so that the two elements of the noise-preventing material, which are hereinafter referred to as ferrite elements, in the housing shell parts are used and then the housing is placed around the electrical cable around. In a further development of the invention can be provided that the means for fixing the ferrite acts on at least one end corner edge of the ferrite element, which extends perpendicular to the interface between the two ferrite elements. Therefore, the fixing device acts in such a way that no forces arise which press the ferrite elements in the direction of the separating surface, so that they can not yield in the reverse direction.

Insbesondere kann in Weiterbildung die Festlegeeinrichtung einen im Bereich einer Ecke der Gehäusehälfte angeordneten schräg zu der Ecke verlaufenden an dem Ferritelement angreifenden Steg aufweisen. Dieser Steg läßt sich bei Herstellung des Gehäuses einfach ohne zusätzlichen Aufwand herstellen.In particular, in a further development, the fixing device may have a web extending in the region of a corner of the housing half and extending obliquely to the corner, acting on the ferrite element. This bridge can be easily produced in production of the housing without additional effort.

Der Steg kann insbesondere eine Kerbe aufweisen, in der die entsprechende Ecke des Ferritelements zu liegen kommt.In particular, the web can have a notch in which the corresponding corner of the ferrite element comes to lie.

Es kann erfindungsgemäß vorgesehen sein, daß der erwähnte Steg einerseits an der Stirnwand und andererseits der Seitenwand des Gehäuses angeformt wird. Zwischen den beiden Stellen, an denen er angeformt ist, verläuft er vorzugsweise frei, so daß er eine gewisse Spannung aufbringen kann.It can be inventively provided that the mentioned web is formed on the one hand on the end wall and on the other hand, the side wall of the housing. Between the two points where it is formed, it is preferably free, so that it can muster a certain tension.

Es ist ebenfalls möglich, daß der Steg geteilt ist, so daß die einander zugeordneten Enden der beiden Teile des Stegs an dem Ferritelement angreifen können.It is also possible that the web is divided so that the mutually associated ends of the two parts of the web can engage the ferrite element.

Insbesondere kann vorgesehen sein, daß die einander zugewandten Enden der beiden Stegteile abgeschrägt verlaufen, wobei die Abschrägung insbesondere so gewählt ist, daß die schrägen Kanten flächig an den Ferritelementen anliegen.In particular, it can be provided that the mutually facing ends of the two web portions are chamfered, wherein the chamfer is chosen in particular so that the oblique edges lie flat against the ferrite elements.

Bei dem zweiteiligen Steg kann erfindungsgemäß vorgesehen sein, daß ein Stegteil an der Stirnwand und der andere an der Seitenwand der Teilschale des Gehäuses angeformt wird.In the two-part web can be inventively provided that a web portion is integrally formed on the end wall and the other on the side wall of the partial shell of the housing.

Erfindungsgemäß kann vorgesehen sein, daß der Steg bzw. die beiden Stegteile nicht bis zu dem Boden der Teilschalen des Gehäuses reicht.According to the invention it can be provided that the web or the two web parts does not extend to the bottom of the subshells of the housing.

Erfindungsgemäß kann die Einrichtung eine Verriegelungseinrichtung zum Verriegeln des Gehäuses in geschlossenem Zustand aufweisen. Damit soll sichergestellt werden, daß sich das Gehäuse nicht wieder öffnet, so daß die Einrichtung wirksam bleibt. Es kann hierbei mit Vorteil vorgesehen werden, daß die Verriegelungseinrichtung derart angeordnet und ausgebildet ist, daß sie nicht über die Außenseite des geschlossenen Gehäuses übersteht, insbesondere vollständig innerhalb des Gehäuses angeordnet ist. Damit wird ein absichtlicher oder unbeabsichtigter Zugriff auf die Verriegelungseinrichtung ausgeschlossen.According to the invention, the device may have a locking device for locking the housing in the closed state. This is to ensure that the housing does not open again, so that the device remains effective. It can be provided with advantage that the locking device is arranged and designed such that it does not protrude beyond the outside of the closed housing, in particular completely disposed within the housing. This precludes intentional or unintentional access to the locking device.

Es kann vorgesehen sein, daß die Verriegelungseinrichtung eine an einer Kante einer Gehäusehälfte angeformte Lasche aufweist, die in eine Ausnehmung in der Kante der anderen Gehäusehälfte verrastend eingreift. Durch diese Anordnung an der Kante kann sichergestellt werden, daß bei geschlossenem Gehäuse die Lasche nicht mehr zugänglich ist. Es kann vorgesehen werden, daß die Ausnehmung nur in das Innere des Gehäuses offen ist.It can be provided that the locking device has an integrally formed on one edge of a housing half lug which engages latching in a recess in the edge of the other housing half. By this arrangement on the edge can be ensured that when the housing is closed, the tab is no longer accessible. It can be provided that the recess is open only in the interior of the housing.

Die Verrastung kann insbesondere so ausgebildet sein, daß sie an den Stirnkanten der Ausnehmung erfolgt.The latching can in particular be designed so that it takes place at the end edges of the recess.

In Weiterbildung kann vorgesehen sein, daß die Lasche im Bereich mindestens einer ihrer einander gegenüberliegenden Stirnenden eine federnde Rastzunge aufweist.In a further development it can be provided that the tab has a resilient latching tongue in the area of at least one of its opposing front ends.

Erfindungsgemäß kann die Verrastung derart ausgebildet werden, daß sie sich einer Öffnung widersetzt. Dies kann durch die Art der Anordnung der Feder beispielsweise erreicht werden.According to the invention, the latch can be formed such that it opposes an opening. This can be achieved by the type of arrangement of the spring, for example.

Um die geschlossene Verriegelungseinrichtung bei Bedarf dennoch wieder öffnen zu können, kann erfindungsgemäß das Gehäuse eine Öffnung aufweisen, durch die hindurch mit Hilfe eines speziellen Werkzeugs an der Verriegelungseinrichtung angegriffen werden kann. Dann wird es einem Spezialisten ermöglicht, die Einrichtung zu öffnen und ggf. auszutauschen.In order to still be able to open the closed locking device when needed, according to the invention, the housing can have an opening through which it can be attacked by means of a special tool on the locking device. Then a specialist is allowed to open the device and replace it if necessary.

Die Durchgangsöffnung für das Kabel kann erfindungsgemäß von zwei Ausnehmungen in den Stirnwänden der beiden Gehäusehälften gebildet werden. Beim Schließen des Gehäuses bilden die beiden einander gegenüberliegenden Ausnehmungen dann die Durchgangsöffnung. Es kann dabei vorgesehen werden, daß die beiden Ausnehmungen längs der einander zugeordneten Kanten der Gehäusehälften versetzt angeordnet sind. Dadurch entstehen Engstellen, die zum Ausgleich verschieden großer Durchmesser der Kabel dienen können, ohne daß die Ausnehmungen von der glatten Form abweichen müssen.The passage opening for the cable can be formed according to the invention of two recesses in the end walls of the two housing halves. When closing the housing, the two opposing recesses then form the passage opening. It can be provided that the two recesses are arranged offset along the mutually associated edges of the housing halves. This creates bottlenecks that can serve to compensate for different diameters of the cable without the recesses must deviate from the smooth shape.

Erfindungsgemäß kann vorgesehen sein, daß die Durchgangsöffnungen von der Kreisform abweichen, also beispielsweise oval oder elliptisch ausgebildet sind.According to the invention it can be provided that the passage openings deviate from the circular shape, that is, for example, are oval or elliptical.

Die beiden Teilschalen können beispielsweise durch ein Filmscharnier miteinander verbunden sein. Es ist aber ebenfalls möglich, daß sie getrennt hergestellt sind und sich durch Stecken miteinander verbinden lassen.The two partial shells can be connected to each other for example by a film hinge. It is also possible that they are made separately and can be connected by plugging together.

In jeder Stirnwand 5 ist eine halbkreisförmige Ausnehmung 10 gebildet, die an der gleichen Stelle jeder Stirnwand 5 angeordnet ist. Klappt man die beiden Gehäusehälften 1, 2 um die durch das Filmscharnier 7 gebildete Achse zusammen, so liegen die freien Kanten der Wände aufeinander, und die beiden Ausnehmungen 10 bilden eine Durchgangsöffnung. Diese Durchgangsöffnung weist Kreisform auf.In each end wall 5, a semicircular recess 10 is formed, which is arranged at the same location of each end wall 5. If the two housing halves 1, 2 are folded together around the axis formed by the film hinge 7, the free edges of the walls lie on one another, and the two recesses 10 form a passage opening. This passage opening has a circular shape.

In den Ecken zwischen den Längsseitenwänden und den Stirnwänden 5 sind Stege 11 angeordnet, die an den Längsseitenwänden 4 bzw. den Stirnwänden 5 einstückig angeformt sind und von den die Trennebene zwischen den beiden Gehäusehälften bildenden Kanten ausgehen. Sie reichen von der Trennebene bis etwas über die Hälfte der Tiefe der Gehäusehälften, also nicht bis zu dem Boden 3. Die Anordnung der Stege 11 geht aus der Fig. 2 deutlicher hervor, die eine Aufsicht auf die Anordnung der Fig. 1 von oben zeigt. Die Stege 11 bestehen aus zwei Teilen 12, 13, die in gegenseitiger Verlängerung angeordnet sind. Ein Stegteil 12 ist an der Innenseite der Stirnwand 5 angeformt und verläuft unter einem Winkel von etwa 45° in Richtung auf die benachbarte Längsseitenwand 4. Der zweite Stegteil 13 ist an der benachbarten Längsseitenwand 4 angeordnet und verläuft ebenfalls unter einem Winkel von etwa 45° in Richtung auf die benachbarte Stirnwand 5. Die der Ecke 14 zugewandten Flächen der Stegteile 12, 13 liegen in einer Ebene. Die beiden freien Kanten 15, 16 der beiden Teile 12, 13 des Stegs 12 sind so abgeschrägt, daß sie eine Ecke mit einem Winkel von 90° bilden. Die Kanten 15, 16 können also an den Seitenflächen 17, 18 der Ecke eines Ferritelements 19 flächig anliegen. Größentoleranzen der Ferritelemente 19 können durch ein geringes Nachgeben der Stegteile 12, 13 in das Innere der Ecke 14 hinein ausgeglichen werden.In the corners between the longitudinal side walls and the end walls 5 webs 11 are arranged, which are integrally formed on the longitudinal side walls 4 and the end walls 5 and emanating from the dividing plane between the two housing halves forming edges. They range from the parting plane to slightly more than half the depth of the housing halves, so not up to the bottom 3. The arrangement of the webs 11 is clear from Fig. 2, which shows a plan view of the arrangement of Fig. 1 from above. The webs 11 consist of two parts 12, 13, which are arranged in mutual extension. A web portion 12 is integrally formed on the inside of the end wall 5 and extends at an angle of about 45 ° in the direction of the adjacent longitudinal side wall 4. The second web portion 13 is disposed on the adjacent longitudinal side wall 4 and also extends at an angle of about 45 ° in Direction to the adjacent end wall 5. The corner 14 facing surfaces of the web parts 12, 13 lie in a plane. The two free edges 15, 16 of the two parts 12, 13 of the web 12 are chamfered so that they form a corner with an angle of 90 °. The edges 15, 16 can thus lie flat against the side surfaces 17, 18 of the corner of a ferrite element 19. Size tolerances of the ferrite elements 19 can be compensated for by a slight yielding of the web parts 12, 13 into the interior of the corner 14.

Die an allen vier Ecken 14 der Gehäusehälften 1, 2 vorhanden Stege 11 bilden eine Festlegeeinrichtung, um ein Ferritelement 19 in jeder Gehäusehälfte 1, 2 festzuhalten. Ein Winkelausgleich für die Ferritelemente 19 ist in Form eines abgerundeten Vorsprungs 20 auf dem Boden 3 jeder Gehäusehälfte 1, 2 vorgesehen.The webs 11 present at all four corners 14 of the housing halves 1, 2 form a fixing device in order to hold a ferrite element 19 in each housing half 1, 2. An angular compensation for the ferrite elements 19 is provided in the form of a rounded projection 20 on the bottom 3 of each housing half 1, 2.

Die einen Teil der Verriegelungseinrichtung bildende Lasche 8 ist auf der Kante 21 der Seitenwand 4 ausgebildet. Ihre Außenseite 22 ist gegenüber der Außenseite 23 der Längsseitenwand 4 nach innen versetzt.The tab 8 forming part of the locking device is formed on the edge 21 of the side wall 4. Its outer side 22 is offset from the outside 23 of the longitudinal side wall 4 inwards.

Die Lasche 8 wirkt mit der Ausnehmung 9 der gegenüberliegenden Seitenwand 4 der anderen Gehäusehälfte 1 zusammen. Diese Ausnehmung ist in das Innere der Gehäusehälfte 1 offen. An beiden Stirnenden 24 der Ausnehmung 9 sind Rippen 25 zur Bildung einer Verrastung angeordnet, siehe Fig. 1.The tab 8 cooperates with the recess 9 of the opposite side wall 4 of the other housing half 1. This recess is open in the interior of the housing half 1. At two front ends 24 of the recess 9 ribs 25 are arranged to form a latching, see Fig. 1st

Die Lasche 8 weist im Bereich ihrer beiden Stirnkanten 25 je eine Rastnase 26 auf, siehe Fig. 4, die am Ende einer Federzunge 27 ausgebildet ist. Die Federzunge 27 ist an der Endfläche 28 der Lasche 8 angeformt. Dies bedeutet, daß sich die in der Verrippung 25 festhaltende Rastnase 26 bei einem Herausziehen nach außen verkeilt und dadurch die Festlegung verstärkt. Wie man der Fig. 2 entnehmen kann, weist die Lasche 8 in das Innere des Gehäuses gerichtete Vorsprünge 29 auf, die über die Innenseite 30 der Längsseitenwand 4 vorspringen. Da die beiden Längsseitenwände 4 im Bereich der Lasche 8 und der Ausnehmung 9 gleich dick sind, stehen diese Vorsprünge 29 auch bei geschlossenem Gehäuse über die Innenwand vor.The tab 8 has in the region of its two end edges 25 each have a latching nose 26, see Fig. 4, which is formed at the end of a spring tongue 27. The spring tongue 27 is integrally formed on the end surface 28 of the tab 8. This means that the latching lug 26 retained in the ribbing 25 wedges outwards when it is withdrawn and thereby reinforces the fixing. As can be seen from Fig. 2, the tab 8 in the interior of the housing directed projections 29 projecting beyond the inner side 30 of the longitudinal side wall 4. Since the two longitudinal side walls 4 in the region of the tab 8 and the recess 9 are the same thickness, these protrusions 29 are also in the closed housing on the inner wall.

Der Boden 3 der Gehäusehälfte 1, die die Ausnehmung 9 enthält, enthält zwei Öffnungen 31, die direkt an die Innenseite der die Ausnehmung 9 aufweisenden Längsseitenwand 4 angrenzen. Durch diese Öffnungen kann man mit einem Werkzeug in das Innere des geschlossenen Gehäuses eingreifen und durch Angreifen an den Vorsprüngen 29 die Rastnasen 26 außer Eingriff mit den Rippen 25 bringen.The bottom 3 of the housing half 1, which contains the recess 9, contains two openings 31, which adjoin the inner side of the recess 9 having longitudinal side wall 4 directly. Through these openings, one can engage with a tool in the interior of the closed housing and bring by engaging the projections 29, the locking lugs 26 out of engagement with the ribs 25.

Fig. 3 zeigt einen Längsschnitt durch die in den Figuren 1 und 2 linke Gehäusehälfte mit der Ausnehmung 9. Dadurch, daß die Verrippung 25 an beiden Stirnwänden 24 der Ausnehmung 9 vorhanden ist und auch die Rastnasen 26 an beiden Enden der Lasche 8, können sich die beiden Rastnasen durch Aufspreizen in den Rippen 25 festlegen.Fig. 3 shows a longitudinal section through the left in Figures 1 and 2 housing half with the recess 9. Due to the fact that the ribbing 25 on both end walls 24 of the recess 9 is present and the locking lugs 26 at both ends of the tab 8, can set the two locking lugs by spreading in the ribs 25.

Fig. 3 zeigt ebenfalls, daß die Stege 11 sich von der Kante ausgehend bis zu der gleichen Stelle erstrecken, wo auch die Ausnehmungen 10 enden, die zusammen die Durchgangsöffnung bilden.Fig. 3 also shows that the webs 11 extend from the edge up to the same point, where the Recesses 10 ends, which together form the passage opening.

Fig. 5 zeigt nun eine Stirnansicht des in den Figuren 1 bis 4 dargestellten Gehäuses bei geschlossenem Gehäuse. Das Gehäuse bildet mit Ausnahme der durch die beiden Ausnehmungen 10 gebildeten Durchgangsöffnung 32 eine glatte Außenseite. Da die beiden Ausnehmungen 10 mit gleichem Durchmesser versehen sind und den gleichen Abstand von beiden Längsseiten haben, wird eine kreisrunde Durchgangsöffnung 32 gebildet.Fig. 5 now shows an end view of the housing shown in Figures 1 to 4 with the housing closed. The housing forms, with the exception of the through hole 32 formed by the two recesses 10, a smooth outer side. Since the two recesses 10 are provided with the same diameter and have the same distance from both longitudinal sides, a circular passage opening 32 is formed.

Bei der Ausführungsform nach Fig. 6 sind die Ausnehmungen ebenfalls halbkreisförmig mit gleichem Durchmesser, jedoch an versetzten Stellen der Seitenwände 5 angeordnet. Dadurch wird eine Durchgangsöffnung 33 gebildet, die an der Trennfläche der beiden Gehäusehälften eine Engstelle bildet, die zur Festlegung an dem Kabel verwendet werden kann.In the embodiment of Fig. 6, the recesses are also semicircular with the same diameter, but arranged at staggered locations of the side walls 5. As a result, a passage opening 33 is formed, which forms a constriction on the parting surface of the two housing halves, which can be used for fixing to the cable.

Bei der in Fig. 17 dargestellten Ausführungsform weisen die beiden Stirnwände 5 der beiden Gehäusehälften ebenfalls je eine Ausnehmung 34 auf, die im dargestellten Beispiel von der Kreisform abweicht, so daß im geschlossenen Zustand des Gehäuses eine ovale Durchgangsöffnung gebildet wird.In the embodiment shown in Fig. 17, the two end walls 5 of the two housing halves also each have a recess 34 which differs in the example shown from the circular shape, so that in the closed state of the housing, an oval passage opening is formed.

Die Figuren 8 bis 10 zeigen Darstellungen, die den Figuren 3 bis 1 entsprechen, bei einer Ausführungsform, die etwas abgeändert ist. Dabei beschränkt sich die Beschreibung auf diejenigen Teile, in denen eine Änderung erfolgt ist.Figs. 8 to 10 are diagrams corresponding to Figs. 3 to 1 in an embodiment which is somewhat modified. The description is limited to those parts in which a change has been made.

Wie man der Fig. 8 entnehmen kann, sind die Stege zum Halten der Eckkanten der Ferrite 19 anders ausgebildet. Die Stege 41 gehen vom Boden der beiden Gehäusehälften aus und reichen bis etwa zur Mitte der Höhe der beiden Gehäusehälften. Die zu der Trennfläche gerichteten Endkanten verlaufen in der Seitenansicht unter einem rechten Winkel, ebenso wie die beiden die Kerbe 42 bildenden Kerbflanken 15, 16, die den Enden der beiden Stegteile 12, 13 entsprechen.As can be seen from FIG. 8, the webs for holding the corner edges of the ferrites 19 are designed differently. The webs 41 extend from the bottom of the two housing halves and extend to about the middle of the height of the two housing halves. The end edges directed towards the separating surface run in the side view at a right angle, as well as the two notch 42 forming notch flanks 15, 16 corresponding to the ends of the two web portions 12, 13.

In der in Fig. 8 in Ansicht zu sehenden Seitenwand ist beidseits der Ausnehmung 9 je ein von der Kante 21 ausgehendes Sackloch 43 gebildet, das zur Aufnahme eines zylindrischen Zapfens 44 bestimmt ist. Die Zapfen 44 sind in der Fig. 10 zu sehen.In the side wall to be seen in FIG. 8, a blind hole 43 extending from the edge 21 is formed on both sides of the recess 9, which is intended to receive a cylindrical pin 44. The pins 44 can be seen in FIG.

Die Lasche 45 entsprechend der Lasche 8 bei der vorhergehenden Ausführungsform ist insgesamt etwas dicker ausgebildet, ebenso wie der zugehörige Teil der Seitenwand 4. Wiederum sind im Boden 3 der die Ausnehmung 9 enthaltenden Gehäusehälfte 2 Durchbrechungen 31 angeordnet, durch die ein Fachmann mit einem Werkzeug an der Lasche 8 angreifen kann, um die Verriegelung zu lösen.The tab 45 corresponding to the tab 8 in the previous embodiment is slightly thicker overall, as well as the associated part of the side wall 4. Again, the recess 9 containing housing half 2 openings 31 are arranged in the bottom 3, by a specialist with a tool the tab 8 can attack to release the lock.

Aus Fig. 10 ist zu sehen, daß statt eines mittig angeordneten Filmscharniers zwei Filmscharniere 7 vorhanden sind, die im Endbereich der Verbindungsstelle zwischen den beiden Gehäusehälften angeordnet sind. Die dadurch jetzt frei zur Verfügung stehenden Kanten 21 der beiden einander zugewandten Seitenwände 4 sind mit je einer Vertiefung 46 und einem der Vertiefung entsprechenden leistenartigen Vorsprung 47 versehen. Beim Zusammenklappen kommen die Vorsprünge 47 in die Vertiefungen 46 zu liegen. Durch den Eingriff dieser Vorsprünge und Vertiefungen und das Zusammenwirken der in die Sacklöcher 43 eingreifenden Zapfen 44 wird eine zusätzliche Verriegelung des Gehäuses gegeben, die auch ein seitliches Abdrehen oder Abscheren der Gehäusehälften fast unmöglich macht. Es ist daher praktisch unmöglich, eine einmal an einem Kabel angebrachte Einrichtung zur Absorption des elektrischen Rauschens wieder von dem Kabel zu lösen. Dies können nur Personen tun, die das nötige Werkzeug haben und wissen, wie es durch die Öffnungen 31 eingesetzt werden kann.From Fig. 10 it can be seen that instead of a centrally arranged film hinge two film hinges 7 are provided, which are arranged in the end region of the connection point between the two housing halves. The thus freely available edges 21 of the two mutually facing side walls 4 are each provided with a recess 46 and a recess corresponding to the strip-like projection 47. When folding the projections 47 come to lie in the recesses 46. Through the engagement of these projections and recesses and the interaction of engaging in the blind holes 43 pin 44 an additional locking of the housing is given, which makes a lateral turning or shearing the housing halves almost impossible. It is therefore practically impossible to detach once again a cable-mounted electrical noise absorption device from the cable. Only people can do this who have the necessary tools and know how it can be used through the openings 31.

Fig. 11 zeigt ein Werkzeug 50 in Form eines Schlüssels, mit dem das zusammengeklappte Gehäuse wieder geöffnet werden kann. Der Schlüssel enthält zwei parallele geradlinige im Querschnitt rechteckige Beine 51, deren Abstand und Größe dem Abstand und der Größe der Öffnungen 31 im Boden der einen Gehäusehalbschale entsprechen. Es wird hierzu auf Figur 2 verwiesen. Die Beine 51 sind ausreichend lang, um mit den Enden 52 an den Vorsprüngen 29 der Rastnasen 26 angreifen zu können. Dadurch wird es möglich, die Rastnasen 26 außer Eingriff mit den Rippen 25 zu bringen, so daß sich das Gehäuse wieder öffnen lässt.Fig. 11 shows a tool 50 in the form of a key, with which the collapsed housing can be opened again. The key includes two parallel rectilinear rectangular cross-section legs 51, the spacing and size of which correspond to the spacing and size of the apertures 31 in the bottom of the housing half-shell. Reference is made to FIG. 2 for this purpose. The legs 51 are sufficiently long to engage with the ends 52 on the projections 29 of the locking lugs 26 can. This makes it possible to bring the locking lugs 26 out of engagement with the ribs 25, so that the housing can be opened again.

Durch die Verwendung eines speziellen auf die Öffnungen 31 abgestimmten Schlüssels kann erreicht werden, dass nur ein Fachmann den in dem Gehäuse angeordneten Rauschabsorber wieder entfernen kann.By using a special key matched to the openings 31, it can be achieved that only a specialist can remove the noise absorber arranged in the housing again.
