Description

Die Erfindung betrifft eine Sicherungsbox für Kraftfahrzeuge mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a fuse box for motor vehicles with the features of the preamble of claim 1.

Bekannte Sicherungsboxen für Kraftfahrzeuge sind in aller Regel im vorderen Fahrzeugbereich, beispielsweise im Motorraum oder im Fußraum des Fahrzeuginnenraums, untergebracht und dienen zur Aufnahme von elektrischen Sicherungen für die einzelnen Verbraucher bzw. für die von der Sicherungsbox abzweigenden Kabelstränge. Die Sicherungsbox bzw. die einen Enden der darin aufgenommenen Sicherungen ist dabei über ein oder mehrere Kabel mit einem Pol der Fahrzeugbatterie, meist dem Pluspol, verbunden. Das jeweils andere Ende der Sicherungen ist mit einem abgehenden Kabel oder Kabelstrang verbunden. Im Fall einer Sicherung zur elektrischen Absicherung eines Verbrauchers ist lediglich der betreffende Verbraucher mit dem abgehenden Ende der Sicherung verbunden. Dient die betreffende Sicherung zur elektrischen Absicherung eines gesamten Kabelstrangs, so sind an diesem Kabelstrang meist mehrere Verbraucher angeschlossen, wobei jeder einzelne Verbraucher nach dem Abzweig von dem Kabelstrang nochmals mit einer separaten Sicherung abgesichert sein kann.Known fuse boxes for motor vehicles are in everything Usually in the front of the vehicle, for example in the engine compartment or housed in the footwell of the vehicle interior and serve to accommodate electrical fuses for the individual Consumers or for those branching off from the fuse box Harnesses. The fuse box or one ends the fuses included in it are over or several cables with one pole of the vehicle battery, mostly that Positive pole, connected. The other end of the fuses is connected to an outgoing cable or harness. in the Case of a fuse for the electrical protection of a consumer is just the consumer in question with the outgoing end of the fuse connected. Serves the one in question Fuse for electrical protection of an entire cable harness, there are usually several consumers on this cable harness connected, with each individual consumer after the Branch from the cable harness again with a separate fuse can be secured.

Es ist bekannt, insbesondere zur Absicherung von Kabelsträngen, sogenannte Streifensicherungen zu verwenden, die kein eigenes Gehäuse besitzen und zur Absicherung der erforderlichen hohen Stromstärken dienen. Im Gegensatz zu den üblichen steckbaren Flachsicherungen, die meist zur elektrischen Absicherung von einzelnen Verbrauchern dienen, ist ein Auswechseln solcher Streifensicherungen in der Regel nur durch Fachpersonal vorgesehen, da bei einer Zerstörung einer Streifensicherung für einen ganzen Kabelstrang ein gravierender Fehler in der Fahrzeugelektrik zu vermuten ist, der zu überhöhten Stromstärken und damit einem Schmelzen des Schmelzbereichs der betreffenden Sicherung geführt hat. Eine derartige Einrichtung ist beispielsweise aus der FR-A-513 414 bekannt.It is known, in particular for securing cable harnesses, to use so-called strip fuses that do not own housing and to secure the necessary serve high currents. In contrast to the usual pluggable flat fuses, mostly for electrical protection serving individual consumers is a substitute such strip security systems usually only by specialist personnel provided because if a strip fuse is destroyed a serious mistake for an entire cable harness in the vehicle electrics is presumed to be excessive Amperages and thus a melting of the melting range of the concerned fuse. Such a facility is known for example from FR-A-513 414.

Dagegen ist das Auswechseln von Sicherungen für einzelne Verbraucher in aller Regel auch für ungeschulte Personen, beispielsweise Fahrzeugführer, ermöglicht, da in diesem Fall unzulässig hohe Stromstärken auch durch kleinere elektrische Fehler, beispielsweise den Kurzschluß des Glühfadens einer Glühbirne bei deren Ausfall, verursacht werden können.In contrast, the replacement of fuses for individual consumers usually also for untrained people, for example Driver, because in this case impermissibly high currents, even from smaller electrical ones Failure, such as shorting the filament one Light bulb if it fails, can be caused.

Bekannte Sicherungsboxen weisen den Nachteil auf, daß bei einem Crash des Fahrzeugs und einer hierdurch verursachten mechanischen Zerstörung von Kabelsträngen zwischen der Sicherungsbox und der Fahrzeugbatterie Kurzschlüsse zwischen den Enden des zerstörten Kabelstrangs, der nach wie vor elektrisch mit einem Pol der Batterie verbunden ist, und der Fahrzeugkarosserie, die das Potential des jeweils anderen Batteriepols aufweist, entstehen können. In solchen Fällen kann es zur Funkenbildung und hierdurch verursachte Brände und Explosionen des Fahrzeugs kommen.Known fuse boxes have the disadvantage that at a crash of the vehicle and one caused thereby mechanical destruction of cable strands between the fuse box and the vehicle battery shorts between the Ends of the destroyed wire harness, which is still electrical is connected to a pole of the battery and the vehicle body, the the potential of the other battery pole exhibits, can arise. In such cases Sparking and resulting fires and explosions of the vehicle.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Sicherungsbox für Kraftfahrzeuge zu schaffen, die auch im Falle eines Crashs des Fahrzeugs Kurzschlüsse und hierdurch verursachte Gefahren sicher vermeidet und welche darüber hinaus einfach und kostengünstig herstellbar und im Fahrzeug montierbar ist.The present invention is therefore based on the object to create a fuse box for motor vehicles that also in the In the event of a crash of the vehicle short circuits and thereby safely avoids the dangers caused and furthermore easy and inexpensive to manufacture and in the vehicle is mountable.

Die Erfindung löst diese Aufgabe mit den Merkmalen des Patentanspruchs 1.The invention solves this problem with the features of the claim 1.

Nach der Erfindung ist das Gehäuse so ausgebildet, daß der Schmelzbereich der Streifensicherungen durch einen im Gehäuse vorgesehenen Abschirmbereich abgeschirmt ist. Hierdurch ergibt sich der Vorteil, daß bei einem Schmelzen der Sicherung kein abgeschmolzenes Material an unerwünschte Stellen innerhalb des Gehäuses gelangt.According to the invention, the housing is designed so that the Melting range of the strip fuses by one in the housing provided shielding area is shielded. This gives the advantage that when the fuse melts no melted material to unwanted locations within the Housing arrives.

Durch das Vorsehen der Sicherungsbox direkt auf der Batterie eines Kraftfahrzeugs, d.h. in unmittelbarer Nähe des mit der Sicherungsbox zu verbindenden Batteriepols ist gewährleistet, daß auch im Fall eines Fahrzeugcrashs kein Zerstören von ungesicherten Kabelsträngen und hierdurch verursachte Funkenbildung auftreten kann.By providing the fuse box directly on the battery a motor vehicle, i.e. in the immediate vicinity of the with the The fuse box to be connected to the battery pole is guaranteed that even in the event of a vehicle crash there is no destruction of unsecured Cable harnesses and the resulting sparking can occur.

Die Sicherungen, insbesondere die Sicherungen für die elektrische Absicherung von Kabelsträngen, sind vorzugsweise als Streifensicherungen ausgebildet, die sehr kostengünstig herstellbar sind.The fuses, especially the fuses for the electrical Protection of cable harnesses are preferably as Strip fuses are formed, which can be produced very inexpensively are.

Bei der bevorzugten Ausführungsform der Sicherungsbox nach der Erfindung ist jeweils ein Ende mehrerer Streifensicherungen mit einer direkt mit dem Pol der Fahrzeugbatterie verbindbaren gemeinsamen Stromschiene verbunden.In the preferred embodiment of the fuse box after the The invention is in each case the end of several strip fuses with a directly connectable to the pole of the vehicle battery common busbar connected.

Gegenüber bekannten Kontaktierungsmöglichkeiten für ein Ende der Streifensicherungen unter Verwendung von Hülsen, die zwischen den Sicherungen und den Anschlußelementen für den Anschluß an den Batteriepol angeordnet sind, sowie von Schrauben und Muttern ergibt sich hierdurch der Vorteil eines minimalen Übergangswiderstandes. Des weiteren ergibt sich hierdurch der Vorteil eines mechanisch sehr einfachen Aufbaus und damit einer kostengünstig fertigbaren Sicherungsbox.Compared to known contact options for an end of strip fuses using sleeves that are between the fuses and the connection elements for the connection are arranged on the battery pole, as well as screws and nuts gives the advantage of minimal Contact resistance. Furthermore, this results in the Advantage of a mechanically very simple structure and thus an inexpensive fuse box.

Bei der bevorzugten Ausführungsform nach der Erfindung weist jede Streifensicherung zwei Bohrungen auf, die zur Befestigung der Sicherung mittels jeweils eines Gewindebolzens und einer Mutter dienen. In the preferred embodiment according to the invention Each strip fuse has two holes for fastening securing by means of a threaded bolt and one Serve mother.

Dasjenige Ende der Streifensicherung, welches die gemeinsame Stromschiene kontaktiert, wird auf einen Gewindebolzen aufgesteckt, der durch eine Bohrung in der gemeinsamen Stromschiene ragt, und mittels einer Mutter sicher fixiert. Zwischen Sicherung und Mutter wird vorzugsweise eine Federscheibe eingesetzt, welche zur Aufrechterhaltung eines vorgegebenen Anzugs-Drehmoments für die Mutter dient.The end of the strip guard, which is the common one Contacted busbar, is attached to a threaded bolt, through a hole in the common track protrudes, and securely fixed by means of a nut. Between backup and nut a spring washer is preferably used, which are used to maintain a specified tightening torque serves for the mother.

Dies ist insbesondere dann erforderlich, wenn die Streifensicherung aus Zink besteht, da sich gezeigt hat, daß durch das Setzverhalten des Materials Zink, insbesondere bei Einwirken von Temperaturzyklen auf die Verbindung zwischen Stromschiene und Streifensicherung, im Lauf der Zeit das Anzugs-Drehmoment reduziert wird.This is particularly necessary if the strip security consists of zinc, since it has been shown that Settling behavior of the material zinc, especially when it acts of temperature cycles on the connection between busbar and strip protection, the tightening torque over time is reduced.

Bei der bevorzugten Ausführungsform der Erfindung sind im Gehäuse seitliche Anschlagflächen zur Verdrehsicherung der eingesetzten Streifensicherung vorgesehen. Hierdurch ergibt sich der Vorteil, daß bei einem Anziehen der Mutter ein Verdrehen oder Verwinden der Streifensicherung vermieden wird.In the preferred embodiment of the invention Housing side stop surfaces to prevent rotation of the provided strip security provided. This gives the advantage that twisting when tightening the nut or twisting of the strip security is avoided.

Nach der bevorzugten Ausführungsform kann der Abschirmbereich gleichzeitig die Funktion einer mechanischen Kodierung für die einzusetzende Streifensicherung übernehmen. Auf diese Weise wird insbesondere das Einsetzen von Sicherungen mit höheren Nennströmen an solche Sicherungsplätze vermieden, die für Sicherungen mit niedrigeren Nennströmen vorgesehen sind. Denn Sicherungen mit größeren Nennströmen weisen bei gleicher Dicke einen breiteren Schmelzbereich auf als Sicherungen mit niedrigeren Nennströmen. According to the preferred embodiment, the shielding area at the same time the function of a mechanical coding for the Take over the strip security to be used. In this way is particularly the insertion of fuses with higher Avoid rated currents to such fuse locations that for Fuses with lower rated currents are provided. Because Fuses with larger nominal currents have the same thickness a wider melting range than fuses with lower ones Rated currents.

In gleicher Weise kann derjenige Bereich des Gehäuses, der zur Aufnahme eines mit der betreffenden Streifensicherung zu verbindenden Kabelschuhs dient, so ausgebildet sein, daß hierdurch eine mechanische Codierung bewirkt ist. Hierzu ist selbstverständlich erforderlich, daß sich die geometrische Form der einzelnen Kabelschuhe an den Enden der Kabel zu den abzusichernden Verbrauchern bzw. an den Enden der abzusichernden Kabelstränge jeweils unterscheidet. Auf diese Weise wird das versehentliche fälschliche Einsetzen eines Kabelschuhs an einem hierzu nicht vorgesehenen Sicherungsplatz vermieden.In the same way, that area of the housing which is used for Inclusion of one to be connected to the relevant strip security Cable lug serves to be designed so that this mechanical coding is effected. This is of course, required that the geometric Shape the individual cable lugs at the ends of the cables to the consumers to be insured or at the ends of the insured Different cable strands. That way the accidental incorrect insertion of a cable lug Avoid a safe place not provided for this.

Zusätzlich zu dieser Codierungsmaßnahme kann das Gehäuse seitliche Öffnungen für das Herausführen der betreffenden Kabel aufweisen, die im wesentlichen dem Durchmesser des betreffenden Kabels entsprechen. Da Kabel zur Führung höherer Ströme dicker ausgeführt werden als Kabel zur Führung niedrigerer Ströme, wird auch hierdurch das Einsetzen von Kabeln für höhere Ströme an Sicherungsplätzen für niedrigere Ströme vermieden. In umgekehrter Weise wird auch das Einsetzen von dünneren Kabeln für niedrigere Ströme an Sicherungsplätzen für höhere Ströme sofort augenfällig, da das Kabel in diesem Fall nicht dicht mit dem Gehäuse abschließt bzw. nicht sicher gehalten ist.In addition to this coding measure, the housing can be lateral Openings for routing the relevant cables have substantially the diameter of the relevant Cable. Because cables for carrying higher currents run thicker than cables for lower routing Currents, this also involves the insertion of cables for higher Avoid currents at fuse locations for lower currents. Conversely, the onset of thinner Cables for lower currents at fuse locations for higher ones Currents are immediately noticeable because the cable is not in this case fits tightly with the housing or is not held securely is.

Bei der bevorzugten Ausführungsform der Sicherungsbox nach der Erfindung sind die Anschlagflächen des Gehäuses für die Verdrehsicherung der Streifensicherungen, die im Gehäuse vorgesehenen Abschirmbereiche für die Schmelzzonen der Sicherungen, die Sicherungs-Codierungsbereiche oder die Kabelschuh-Codierungsbereiche auf einem in das Gehäuse einsetzbaren Zwischenboden ausgebildet. Hierdurch ergibt sich der Vorteil einer flexiblen Anpassung der Sicherungsbox für unterschiedliche Sicherungswerte bzw. für unterschiedliche Anzahlen von Sicherungen. Zudem können die Gewindebolzen in diesem Fall einfach dadurch im Gehäuse unverlierbar gehalten sein, daß die Gewindebereiche der Gewindebolzen durch Bohrungen in dem Zwischenboden ragen und die Kopfteile der Gewindebolzen zwischen dem Gehäuseboden der Unterseite des Zwischenbodens gehalten sind. In the preferred embodiment of the fuse box after the Invention are the stop faces of the housing for the anti-rotation the strip fuses provided in the housing Shielding areas for the fuse's melting zones, the fuse coding areas or the cable lug coding areas on a shelf that can be inserted into the housing educated. This gives the advantage of a flexible adjustment of the fuse box for different Fuse values or for different numbers of fuses. In addition, the threaded bolts can be simple in this case be held captive in the housing that the thread areas the threaded bolt through holes in the mezzanine protrude and the head parts of the threaded bolts between the Housing bottom of the underside of the mezzanine are held.

Bei der bevorzugten Ausführungsform der Sicherungsbox ragt der Gewindebolzen für die Halterung des nicht mit dem Batteriepol verbundenen Endes der Streifensicherung durch eine Federhülse, die unverlierbar im Gehäuse gehalten, vorzugsweise eingepreßt ist. Die Federhülse kann bei Verwendung eines Zwischenbodens in eine in diesem vorgesehene Bohrung eingepreßt sein. Die Federhülse weist dabei einen axial zu dem Gewindeteil des Gewindebolzens verlaufenden Hülsenbereich für das Einpressen und einen radial verlaufenden Kragen zur federnden Auflage der Streifensicherung auf. Der im wesentlichen radial verlaufende Kragen bewirkt durch seine federnde Eigenschaft ein Aufrechterhalten des ursprünglichen Anzugs-Drehmoments für die Mutter zur Befestigung des betreffenden Kabelschuhs auf dem Gewindebolzen bzw. dem betreffenden Sicherungsende.In the preferred embodiment of the fuse box, the protrudes Threaded bolt for holding the not with the battery pole connected end of the strip security by a spring sleeve, which are held captive in the housing, preferably pressed is. The spring sleeve can be used when using an intermediate floor be pressed into a bore provided in this. The Spring sleeve has an axial to the threaded part of the Threaded bolt-running sleeve area for pressing and a radially extending collar for resilient support of the Strip security. The essentially radial one Collar maintains due to its resilient properties of the original tightening torque for the mother for fastening the relevant cable lug on the threaded bolt or the relevant backup end.

Durch das Vorsehen von unverlierbar im Gehäuse gehaltenen Gewindebolzen und Federhülsen ergibt sich der Vorteil, daß die Sicherungsbox vom Hersteller der Sicherungsbox mit bereits eingesetzten Streifensicherungen lieferbar ist, wobei auf den Gewindebolzen zur Befestigung der Sicherungsenden, die nicht mit dem abzusichernden Batteriepol verbunden sind, keine Mutter zur Halterung des Bolzens, der Sicherung bzw. der Federhülse aufgeschraubt sein muß. Beim Einbau der Sicherungsbox in das Fahrzeug müssen dann lediglich die Sicherungsbox auf der Batterie befestigt und die Kabelschuhe mit den betreffenden Enden der Streifensicherungen verbunden werden.By providing captive ones in the housing Threaded bolts and spring sleeves have the advantage that the Fuse box from the manufacturer of the fuse box with already used strip fuses is available, with the Threaded bolts for securing the fuse ends that are not are connected to the battery pole to be protected, not a nut for holding the bolt, the fuse or the spring sleeve must be screwed on. When installing the fuse box in the vehicle then only need the fuse box on the Battery attached and the cable lugs with the concerned Ends of the strip fuses are connected.

Die in Fig. 1 dargestellte erfindungsgemäße Sicherungsbox 1 umfaßt ein Gehäuse 3, welches im wesentlichen aus einem Bodenteil 5 und einem Deckelteil 7 besteht, welches zumindest den Aufnahmebereich 9 (Fig. 2) für die Sicherungen abdeckt.The fuse box 1 according to the invention shown in FIG. 1 comprises a housing 3, which consists essentially of a bottom part 5 and a cover part 7, which at least the Receiving area 9 (Fig. 2) covers for the fuses.

Wie aus den Fig. 1 und 2 ersichtlich, ist das Deckelteil 7 über Gelenke 11 verschwenkbar mit dem Bodenteil 5 verbunden und über entriegelbare rastende Verschlußeinrichtungen 13 öffen- und schließbar. In den Sicherungsaufnahmebereich 9 ragt eine aus Stabilitätsgründen vorzugsweise L-förmig ausgebildete Stromschiene 15, deren eines Ende direkt mit dem betreffenden Pol 17 einer Batterie eines Kraftfahrzeugs verbunden ist (Fig. 5).As can be seen from FIGS. 1 and 2, the cover part 7 pivotally connected to the base part 5 via joints 11 and via unlockable latching locking devices 13 can be opened and closed. Protrudes into the fuse receiving area 9 one which is preferably L-shaped for reasons of stability Busbar 15, one end of which is directly connected to the relevant one Pole 17 of a battery of a motor vehicle is connected (Fig. 5).

Wie aus den Fig. 1, 2 und 5 ersichtlich, dient der in den Zeichnungen 1 und 2 rechts dargestellte und in Fig. 5 vergrößerte Bereich der Sicherungsbox 1 gleichzeitig zur Abdeckung des betreffenden Pols, vorzugsweise des Plus-Pols, der Batterie. Dieser Bereich kann selbstverständlich ebenfalls mittels eines Deckels öffenbar ausgebildet sein, so daß der betreffende Pol der Batterie auch ohne ein Öffnen des Deckelteils bzw. komplettes Entfernen der Sicherungsbox 1 zugänglich ist, beispielsweise für das Anschließen eines Starterkabels.As can be seen from FIGS. 1, 2 and 5, the serves in the Drawings 1 and 2 shown on the right and enlarged in Fig. 5 Area of fuse box 1 at the same time for covering of the relevant pole, preferably the positive pole, of the battery. This area can of course also by means of of a lid can be designed to be openable, so that the relevant one Pole of the battery even without opening the cover part or complete removal of the fuse box 1 is accessible, for example for connecting a starter cable.

Aus der Draufsicht gemäß Fig. 2 bei geschnittenem Deckelteil 7 ist ersichtlich, daß insgesamt fünf Streifensicherungen 19 mit jeweils einem Ende mechanisch und elektrisch mit der Stromschiene 15 verbunden sind. Wie in Fig. 4 dargestellt, ist hierzu zur Halterung jeder der Streifensicherungen 15 ein Gewindebolzen 21 vorgesehen, der, wie im Fall des dargestellten Ausführungsbeispiels, als Kopfschraube ausgebildet sein kann. Der Gewindebolzen 21 ragt mit seinem Gewindeteil durch jeweils eine Bohrung 23 in der Stromschiene 15. Die Stromschiene 15 ist dabei mittels eines Teils 25, welches mit dem Bodenteil 5 des Gehäuses 3 verbunden ist und eine die Stromschiene 15 übergreifende Schulter 27 aufweist, sowie mittels eines in das Bodenteil 5 einsetzbaren Zwischenbodens im Gehäuse fixiert, wobei der Zwischenboden 29 die Stromschiene 15 ebenfalls mittels eines Bereichs 29a übergreift.2 with the cover part 7 cut it can be seen that a total of five strip fuses 19 with one end each mechanically and electrically with the busbar 15 are connected. As shown in Fig. 4, is for this purpose to hold each of the strip fuses 15 Threaded bolt 21 is provided which, as in the case of the illustrated Embodiment, be designed as a head screw can. The threaded bolt 21 projects through with its threaded part each have a hole 23 in the busbar 15. The busbar 15 is by means of a part 25 which with the Bottom part 5 of the housing 3 is connected and the busbar 15 overlapping shoulder 27, and by means of an insertable in the bottom part 5 shelf in the housing fixed, with the intermediate floor 29 the busbar 15 also overlaps by means of a region 29a.

Da der Gewindebolzen 21 als Kopfschraube ausgebildet ist, deren Kopf in einem Aufnahmebereich 31 zwischen dem Bodenteil 5 und der fixierten Stromschiene 15 aufgenommen ist, erfolgt auf diese Weise eine unverlierbare Fixierung des Gewindebolzens 21.Since the threaded bolt 21 is designed as a cap screw, whose head in a receiving area 31 between the bottom part 5 and the fixed busbar 15 is added takes place in this way an captive fixation of the threaded bolt 21.

Die betreffende Streifensicherung 19, die in Fig. 3 in vergrößerter Draufsicht als Einzelteil dargestellt ist, weist für das Aufstecken auf den Gewindebolzen 21 eine Bohrung 33 auf.The relevant strip fuse 19, which is enlarged in FIG. 3 Top view is shown as a single item points for plugging onto the threaded bolt 21 has a bore 33.

Wie in Fig. 4 dargestellt, wird die Streifensicherung 19 nach dem Aufstecken auf den Gewindebolzen 21 mittels einer Mutter 35 mit der Stromschiene 15 verbunden, wobei zwischen der Unterseite der Mutter 35 und der Oberseite der Streifensicherung 19 eine Federscheibe 37 angeordnet ist. Die Federscheibe 37 gewährleistet infolge ihrer federnden Eigenschaft eine dauernde Aufrechterhaltung eines vorgegebenen Anzugs-Drehmoments bzw. einer vorgegebenen Anpreßkraft der Streifensicherung 19 an die Stromschiene 15.As shown in Fig. 4, the strip fuse 19 is after plugging onto the threaded bolt 21 by means of a nut 35 connected to the busbar 15, being between the bottom the nut 35 and the top of the strip fuse 19 a spring washer 37 is arranged. The spring washer 37 ensures a permanent due to its resilient property Maintaining a specified tightening torque or a predetermined contact pressure of the strip fuse 19 to the busbar 15.

Das jeweils andere Ende der Streifensicherungen 19 wird ebenfalls mittels eines weiteren Gewindebolzens 39 im Gehäuse 3 gehalten, wobei der Gewindebolzen 39 wiederum als Kopfschraube ausgebildet ist, deren Kopf in einem Aufnahmebereich 41 im Bodenteil 5 des Gehäuses 3 aufgenommen ist. Der Gewindeteil des Gewindebolzens 39 ragt durch eine Bohrung 43 im Zwischenboden 29, wodurch der Bolzen 39 wiederum unverlierbar im Gehäuse 3 fixiert ist. Der Zwischenboden 29 kann hierzu beispielsweise schnappbar mit dem Bodenteil 5 verbunden sein.The other end of the strip fuses 19 is also by means of a further threaded bolt 39 in the housing 3 held, the threaded bolt 39 in turn as a cap screw is formed, the head in a receiving area 41 in the Bottom part 5 of the housing 3 is added. The threaded part of the threaded bolt 39 protrudes through a hole 43 in the intermediate floor 29, whereby the bolt 39 in turn captive in the housing 3 is fixed. The intermediate floor 29 can, for example, do this be snapped connected to the bottom part 5.

Selbstverständlich kann der Zwischenboden 29 jedoch auch fest mit dem Bodenteil 5 verbunden, beispielsweise verklebt sein. Hierdurch kann die Dichtigkeit des Gehäuses bei geschlossenem Deckel leichter gewährleistet werden.Of course, the intermediate floor 29 can also be fixed connected to the bottom part 5, for example glued. As a result, the tightness of the housing when closed Lids can be guaranteed more easily.

In die Bohrung 43 im Zwischenboden 29 ist eine Federhülse 45 mit ihrem im wesentlichen axial zum Gewindeteil des Gewindebolzens 39 verlaufenden Hülsenteil eingepreßt. Durch das Einpressen ist die Federhülse 45 ebenfalls unverlierbar im Gehäuse bzw. im Zwischenboden 29 gehalten.A spring sleeve 45 is in the bore 43 in the intermediate floor 29 with their essentially axial to the threaded part of the threaded bolt 39 running sleeve part pressed. By pressing the spring sleeve 45 is also captive in the housing or held in the intermediate floor 29.

Ein oberer sich im wesentlichen radial erstreckender Kragen der Federhülse 45 dient als Auflage für das betreffende Ende der Streifensicherung 19, wobei die in diesem Ende vorgesehene Bohrung 33 wieder für das Aufstecken der Streifensicherung 19 auf den Gewindebolzen 39 dient.An upper radially extending collar the spring sleeve 45 serves as a support for the end in question the strip fuse 19, the provided in this end Hole 33 again for attaching the strip fuse 19 serves on the threaded bolt 39.

Auf den Gewindebolzen 39 ist in nicht dargestellter Weise ein Kabelschuh aufsteckbar, in welchem ebenfalls eine entsprechende Bohrung oder Ausnehmung vorgesehen ist. Der Kabelschuh kann mittels einer in den Figuren gestrichelt dargestellten Mutter 47 mechanisch fixiert und elektrisch mit der Streifensicherung 19 verbunden werden. Der Kragen der Federhülse 45 dient mit seinen federnden Eigenschaften zur Aufrechterhaltung eines vorgegebenen Anzugs-Drehmoments bzw. zur Aufrechterhaltung einer vorgegebenen Anpreßkraft des Kabelschuhs an die Streifensicherung 19.On the threaded bolt 39 is in a manner not shown Cable lug attachable, in which also a corresponding Bore or recess is provided. The cable lug can by means of a mother shown in dashed lines in the figures 47 mechanically fixed and electrical with the strip security 19 are connected. The collar of the spring sleeve 45 also serves its resilient properties to maintain a specified tightening torque or for maintenance a predetermined contact pressure of the cable lug to the strip fuse 19th

Auf dem Zwischenboden 29 sind an den seitlichen Bereichen der Streifensicherungen 19 wiederum seitliche Wandungen 61 vorgesehen, welche als Anschlagflächen für die Seiten der Streifensicherungen 19 dienen. Hierdurch wird ein Verdrehen und Verwinden der Streifensicherungen beim Anziehen der Muttern 35 bzw. 47 vermieden. Die Wandungen dienen darüber hinaus gleichzeitig zur Abschirmung der Schmelzbereiche 19a der Streifensicherungen 19. Hierdurch werden unerwünschte Einflüsse beim Schmelzen einer Streifensicherung 19 auf die übrigen Sicherungen und Anschlußelemente vermieden.On the intermediate floor 29 are the Strip fuses 19 in turn provided lateral walls 61, which as stop surfaces for the sides of the strip fuse 19 serve. This will twist and Twist the strip retainers when tightening the nuts 35 or 47 avoided. The walls also serve simultaneously for shielding the melting areas 19a of the strip fuses 19. As a result, undesirable influences on Melt a strip fuse 19 on the other fuses and connecting elements avoided.

Wie in Fig. 2 dargestellt, sind anschließend an die Bolzen 39 zur Befestigung jeweils eines Kabelschuhs Kabelschuh-Codierungsbereiche 49 vorgesehen, welche zur Aufnahme des betreffenden Kabelschuhs dienen. Um eine Codierung zu gewährleisten, ist jeder Codierungsbereich 49 verschiedenartig ausgebildet, so daß nur der Kabelschuh mit der jeweils im wesentlichen komplementären Außenkontur in den betreffenden Codierungsbereich 49 einsetzbar ist. Auf diese Weise wird eine falsche Zuordnung eines Kabelschuhs zur zugehörigen Streifensicherung 19 vermieden. Hierzu können auf dem Zwischenboden 29 Wandungen 51 vorgesehen sein, welche die Codierungsbereiche 49 seitlich begrenzen und die jeweilige Kontur bestimmen.As shown in FIG. 2, the bolts 39 are connected for attaching one cable lug each to cable lug coding areas 49 is provided, which for receiving the relevant Serve cable lug. To ensure coding, each coding area 49 is designed differently, so that only the cable lug with each essentially complementary outer contour in the relevant coding area 49 can be used. This way, a wrong one Assignment of a cable lug to the associated strip fuse 19 avoided. For this purpose 29 walls can be on the intermediate floor 51 are provided, which the coding areas 49 laterally limit and determine the respective contour.

Das mit dem jeweiligen Kabelschuh kontaktierte Kabel ist durch jeweils eine Öffnung 53 in der Seitenwandung des Gehäuses 3 nach außen geführt. Der Durchmesser jeder Öffnung 53 entspricht dabei dem Durchmesser des jeweiligen Kabels. Auch hierdurch kann wiederum eine zusätzliche Codierung bewirkt werden.The cable contacted with the respective cable lug is through each have an opening 53 in the side wall of the housing 3 led to the outside. The diameter of each opening 53 corresponds the diameter of the respective cable. Also this can in turn cause additional coding become.

Wie aus den Fig. 1 und 2 ersichtlich, können die Öffnungen 53 zum einen durch im wesentlichen vertikal verlaufende, nach oben offene Schlitze in einer Seitenwandung des Zwischenbodens 29 und zum anderen durch nach unten offene Schlitze im Deckelteil 7 gebildet sein. Auf diese Weise ergibt sich der Vorteil, daß durch verschiedene Zwischenböden 29 und Deckelteile 7 die Sicherungsbox 1 an die Anzahl der benötigten Streifensicherungen und an die Dicke der abzusichernden Kabel bzw. Kabelstränge anpaßbar ist. Für eine derartige Anpassung muß lediglich das Spritzwerkzeug für den Zwischenboden und ggf. das Spritzwerkzeug für das Deckelteil entsprechend geändert werden.As can be seen from FIGS. 1 and 2, the openings 53 on the one hand by essentially vertical, after Open slots at the top in a side wall of the intermediate floor 29 and on the other hand through slits in the cover part which are open at the bottom 7 be formed. In this way there is the advantage that through different shelves 29 and lid parts 7 the Fuse box 1 to the number of strip fuses required and the thickness of the cable or cable harness to be protected is customizable. All that is required for such an adjustment the injection mold for the intermediate floor and, if necessary, the injection mold for the cover part can be changed accordingly.

Die bisher erläuterten Streifensicherungen 19 dienen in aller Regel zur Absicherung von Kabelsträngen und werden in aller Regel nur von geschultem Fachpersonal ausgetauscht, da bei einem Ansprechen einer Streifensicherung mit Nennströmen von 100 A und mehr in aller Regel ein gravierender Defekt in der Elektrik des Kraftfahrzeugs vorliegt. The strip fuses 19 explained so far serve in all Rule for securing wiring harnesses and are used in all As a rule, only replaced by trained specialists, as with response of a strip fuse with rated currents of 100 A and more usually a serious defect in the Electrical system of the motor vehicle is present.

Darüber hinaus dient die Sicherungsbox 1 jedoch auch zur Aufnahme von herkömmlichen Sicherungen zur elektrischen Absicherung von Verbrauchern, beispielsweise von Antiblockiersystemen, Airbags, Scheinwerfern etc. Diese Sicherungen sind in Fig. 2 mit den Bezugszeichen 55 versehen und können in üblicher Weise als steckbare Flachsicherungen ausgebildet sein. Die Kontaktierung dieser Sicherungen erfolgt in üblicher Weise mittels Anschlußkontakten 57 (Fig. 4), wobei am Gehäuse 3 bzw. am Bodenteil 5 ein Aufnahmebereich 59 zur Aufnahme eines oder mehrerer Stecker zur Kontaktierung der Flachsicherungen vorgesehen ist.In addition, the fuse box 1 is also used for recording from conventional fuses to electrical protection by consumers, for example anti-lock braking systems, Airbags, headlights etc. These fuses are in Fig. 2 provided with the reference numeral 55 and can in the usual Be designed as pluggable flat fuses. These fuses are contacted in the usual way by means of connection contacts 57 (FIG. 4), on the housing 3 or on the bottom part 5 a receiving area 59 for receiving one or Several plugs are provided for contacting the flat fuses is.

Wie bereits erwähnt, ist das Deckelteil 7 in Verbindung mit dem Bodenteil 5 des Gehäuses 3 so ausgebildet, daß sich beim Schließen des Deckelteils 7 ein wasser- und feuchtigkeitsdichter Abschluß ergibt.As already mentioned, the cover part 7 is in connection with the bottom part 5 of the housing 3 so designed that when Closing the lid part 7 a water and moisture proof Conclusion results.
