Description

Stand der TechnikState of the art

Die Erfindung geht aus von einer Vorrichtung zur Zugentlastung von Einzeladern nach der Gattung des Hauptanspruchs.The invention relates to a device for strain relief of individual wires according to the preamble of the main claim.

Es ist schon eine Vorrichtung zur Zugentlastung bekannt, mit zumindest einem Anschlussstecker, mit dem eine Einzelader elektrisch kontaktiert ist und mit einem Zugentlastungselement, das einen Schlitz zur Halterung der Einzelader aufweist. Nachteilig ist, dass der Schlitz des Zugentlastungselementes nur eine einzige Einzelader aufnehmen kann. Bei der Einführung von weiteren Einzeladern in den Schlitz würde die Presspassung und damit die Wirkung als Zugentlastung nicht mehr gewährleistet sein.There is already known a device for strain relief, with at least one connector, with which a single wire is electrically contacted and with a strain relief element having a slot for holding the single wire. The disadvantage is that the slot of the strain relief can accommodate only a single vein. When introducing further single wires into the slot, the interference fit and thus the effect as strain relief would no longer be guaranteed.

Eine weitere gattungsgemäße Ausführung dem Oberbegriff des Anspruchs 1 entsprechend, ist aus US 4 430 523 A1 bekannt.A further generic embodiment corresponding to the preamble of claim 1, is made US 4 430 523 A1 known.

Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße Vorrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, dass mehrere Einzeladern in einer ersten Ausnehmung unter Presspassung vorgesehen werden können, indem die erste Ausnehmung zumindest zwei Bereiche zur Lagerung von Einzeladern unterschiedlichen Querschnitts aufweist, wobei zwischen den Bereichen eine kontinuierliche Änderung der Breite erfolgt. Die zwei Einzeladern unterschiedlicher Dicke sind an dem gleichen Anschlussstecker befestigt. Durch die erfindungsgemäße Zugentlastung ist die Kontaktierung der beiden Einzeladern mit dem Anschlussstecker einfacher und kostengünstiger, da keine weitere Ausnehmung für die zweite Einzelader erforderlich ist und kein unterschiedlicher Verlauf der Einzeladern zu dem Anschlusstecker gegeben ist.The device according to the invention with the characterizing features of the main claim has the advantage that several individual wires can be provided in a first recess under interference fit by the first recess has at least two areas for storage of individual wires of different cross sections, wherein between the areas a continuous change of Width is done. The two single wires of different thickness are attached to the same connector. Due to the strain relief according to the invention, the contacting of the two individual wires with the connector is easier and less expensive, since no further recess for the second single wire is required and no different course of the individual wires is given to the connector plug.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Vorrichtung möglich.The measures listed in the dependent claims advantageous refinements and improvements of the main claim device are possible.

Besonders vorteilhaft ist, wenn für die beiden Bereiche der ersten Ausnehmung eine Presspassung vorgesehen ist, da auf die Einzeladern wirkende Zugbelastungen auf diese Weise nicht auf die Verbindung am Anschlussstecker, sondern auf das Zugentlastungselement wirken.It is particularly advantageous if an interference fit is provided for the two regions of the first recess, since tensile loads acting on the individual wires do not act in this way on the connection on the connector, but on the strain relief element.

Weiterhin vorteilhaft ist, wenn die beiden Bereiche eine gewölbte Vertiefung aufweisen, da auf diese Weise eine definierte Position der Einzelader in der ersten Ausnehmung erreicht ist. Außerdem wird eine höhere Auszugskraft senkrecht zur Kabelachse benötigt, um die Einzelader aus dem Zugentlastungselement zu lösen, und damit eine höhere Sicherheit gegen versehentliches Lösen der Einzeladern erreicht. Außerdem vorteilhaft ist, wenn der Abstand zwischen den Einzeladern möglichst gering ist, damit das dünne untere Kabel einen oberen Anschlag aufweist.It is also advantageous if the two areas have a curved depression, since in this way a defined position of the individual wire in the first recess is achieved. In addition, a higher pull-out force is required perpendicular to the cable axis to release the single wire from the strain relief, and thus achieved a higher level of security against accidental release of the individual wires. It is also advantageous if the distance between the individual wires is as small as possible, so that the thin lower cable has an upper stop.

Sehr vorteilhaft ist es, wenn die erste Ausnehmung senkrecht zur Durchgangsrichtung offen ausgebildet ist, da die Einzeladern auf diese Weise sehr einfach und maschinell in die erste Ausnehmung eingeführt werden können.It is very advantageous if the first recess is designed to be open perpendicular to the passage direction, since the individual cores can be introduced very easily and mechanically into the first recess in this way.

Auch vorteilhaft ist, wenn die erste Ausnehmung an ihrem offenen Ende zumindest eine Schräge aufweist, da sich die Einzeladern auf diese Weise einfacher in die erste Ausnehmung einführen lassen.It is also advantageous if the first recess has at least one bevel at its open end, since the individual cores can be introduced more easily into the first recess in this way.

Gemäß einem ersten Ausführungsbeispiel ist die erste Ausnehmung schlitzförmig, U-förmig, spaltförmig, langlochförmig oder ähnlich ausgebildet.According to a first embodiment, the first recess is slot-shaped, U-shaped, slit-shaped, elongated hole-shaped or similar.

Darüber hinaus vorteilhaft ist, wenn der Anschlussstecker eine zweite Ausnehmung zur Befestigung der zumindest zwei Einzeladern aufweist, da sich die beiden Einzeladern auf diese Weise besonders einfach und zuverlässig an dem Anschlussstecker befestigen lassen, beispielsweise mittels Crimpen oder Schweißen.Moreover, it is advantageous if the connector has a second recess for fixing the at least two individual wires, since the two individual wires can be fastened to the connector in a particularly simple and reliable manner, for example by means of crimping or welding.

Beschreibung der AusführungsbeispieleDescription of the embodiments

Fig.1 zeigt eine erfindungsgemäße Vorrichtung zur Zugentlastung von Einzeladern gemäß einem ersten Ausführungsbeispiel. Fig.1 shows a device according to the invention for strain relief of individual wires according to a first embodiment.

Die Vorrichtung dient dazu, Verbindungen von elektrischen Leitungen, beispielsweise Einzeladern, mit elektrischen Anschlüssen vor Zugbelastungen und damit vor einer Beschädigung oder Zerstörung zu sichern.The device serves to secure connections of electrical lines, for example single cores, with electrical connections against tensile loads and thus against damage or destruction.

Die Vorrichtung ist an einem beliebigen elektrischen Verbraucher 1, beispielsweise einer Elektrokraftstoffpumpe oder einem Kraftstofffördermodul, vorgesehen. Sie weist beispielsweise zwei Anschlussstecker 2 auf, die über elektrische Leitungen 3 mit einer Spannungsquelle 4 verbunden sind. Die elektrischen Leitungen 3 sind fest an den Anschlusssteckern 2 befestigt, beispielsweise mittels Schweißen, Löten, Crimpen, Quetschen oder Pressen.The device is provided on any electrical load 1, for example an electric fuel pump or a fuel delivery module. It has, for example, two connector 2, which are connected via electrical lines 3 to a voltage source 4. The electrical leads 3 are firmly attached to the connector plugs 2, for example by means of welding, soldering, crimping, crimping or pressing.

Damit die elektrische Verbindung an den Anschlusssteckern 2 nicht durch Erschütterungen oder Schwingungen beschädigt werden kann, ist zumindest ein Zugentlastungselement 7 vorgesehen, das auf die elektrischen Leitungen 3 wirkende Zugbelastungen aufnimmt, so dass diese nicht auf die Verbindung an den Anschlusssteckern 2 wirken. Das Zugentlastungselement 7 ist nahe den Anschlusssteckern 2 angeordnet und zu diesen beabstandet. Die elektrischen Leitungen 3 sind mittels einer Ummantelung elektrisch isoliert, selbstverständlich jedoch nicht am Anschlussstecker 2.So that the electrical connection to the connection plugs 2 can not be damaged by vibrations or vibrations, at least one strain relief element 7 is provided, which absorbs tensile stresses acting on the electrical leads 3 so that they do not act on the connection to the connection plugs 2. The strain relief element 7 is arranged near the connection plugs 2 and spaced therefrom. The electrical lines 3 are electrically insulated by means of a sheath, but of course not on the connector 2.

Das Zugentlastungselement 7 weist zumindest eine erste Ausnehmung 8 zur Halterung zumindest einer elektrischen Leitung 3 auf. Es ist beispielsweise als steckerförmige Wandung ausgebildet, in der die erste Ausnehmung 8 als Durchgangsöffnung vorgesehen ist. Die erste Ausnehmung 8 ist beispielsweise senkrecht zur Durchgangsrichtung offen ausgebildet, so dass die elektrische Leitungen 3 von oben oder seitlich in die erste Ausnehmung 8 einführbar sind. Die erste Ausnehmung 8 ist gemäß einer Ausführung schlitzförmig, U-förmig, spaltförmig, langlochförmig oder ähnlich ausgebildet. An ihrem offenen Ende weist die erste Ausnehmung 8 beispielsweise eine oder zwei Einführschrägen 9 auf, die das Einfädeln der elektrischen Leitungen 3 erleichtern. Die elektrische Leitung 3 verläuft durch die erste Ausnehmung 8 hindurch bis an den Anschlussstecker 2. Der Anschlussstecker 2 weist eine zweite Ausnehmung 10 zur Befestigung der elektrischen Leitung 3 auf, durch die das nicht isolierte Ende der elektrischen Leitung 3 hindurchragt. Beispielsweise ist die zweite Ausnehmung 10 schlitzförmig, U-förmig, spaltförmig, langlochförmig oder ähnlich ausgeführt. Das nicht isolierte Ende der elektrischen Leitung 3 ist mit dem Anschlussstecker 2 fest verbunden. Beispielsweise ist das Zugentlastungselement 7 derart ausgebildet und angeordnet, dass die elektrische Leitung 3 zwischen dem Zugentlastungselement 7 und dem Anschlussstecker 2 im wesentlichen geradlinig und in einer horizontalen Ebene verläuft. Beispielsweise sind die erste Ausnehmung 8 und die zweite Ausnehmung 10 fluchtend zueinander angeordnet.The strain relief element 7 has at least one first recess 8 for holding at least one electrical line 3. It is designed for example as a plug-shaped wall, in which the first recess 8 is provided as a passage opening. The first recess 8 is designed to be open, for example, perpendicular to the passage direction, so that the electrical leads 3 can be introduced from above or laterally into the first recess 8. The first recess 8 is according to one embodiment slit-shaped, U-shaped, slit-shaped, elongated hole-shaped or similar. At its open end, the first recess 8, for example, one or two insertion bevels 9, which is the threading of the electrical Lines 3 easier. The electrical line 3 extends through the first recess 8 through to the connector 2. The connector 2 has a second recess 10 for attachment of the electrical line 3, through which the non-insulated end of the electrical line 3 protrudes. For example, the second recess 10 is slot-shaped, U-shaped, slit-shaped, oblong-shaped or similar. The non-insulated end of the electrical line 3 is firmly connected to the connector 2. For example, the strain relief element 7 is designed and arranged such that the electrical line 3 between the strain relief element 7 and the connector 2 is substantially rectilinear and in a horizontal plane. For example, the first recess 8 and the second recess 10 are arranged in alignment with each other.

Erfindungsgemäß ist vorgesehen, dass die erste Ausnehmung 8 zwei Bereiche 11,12 zur Lagerung von zwei elektrischen Leitungen 3 unterschiedlichen Querschnitts aufweist, wobei zwischen den Bereichen 11,12 ein mittlerer Bereich 13 vorgesehen ist, in dem eine kontinuierliche Änderung der Breite erfolgt. Der untere Bereich 11 hat eine geringere Breite als der obere Bereich 12. Dem entsprechend nimmt der untere Bereich 11 eine elektrische Leitung 3.1 mit einem vorbestimmten ersten Durchmesser bzw. Querschnitt auf und der obere Bereich 12 eine elektrische Leitung 3.2 mit einem vorbestimmten zweiten Durchmesser bzw. Querschnitt, der größer ist als der der elektrischen Leitung 3.1 im unteren Bereich 11. Zwischen den elektrischen Leitungen 3.1,3.2 und den Bereichen 11,12 ist eine Presspassung vorgesehen, die eine vorbestimmte Haltekraft aufnehmen kann. Je höher die Presspassung ist, desto höher ist die von dem Zugentlastungselement 7 aufnehmbare Haltekraft. Andererseits darf die Presspassung nicht zu hoch gewählt werden, um ein Beschädigen der Isolierung der elektrischen Leitung 3 zu vermeiden. Die elektrischen Leitungen 3 sind derart in der ersten Ausnehmung 8 angeordnet, dass ihr Abstand zueinander möglichst gering ist, so dass die obere elektrische Leitung 3 für die untere elektrische Leitung 3 einen Anschlag bildet.According to the invention, it is provided that the first recess 8 has two regions 11, 12 for the storage of two electrical lines 3 of different cross-section, wherein between the regions 11, 12 a middle region 13 is provided, in which a continuous change of the width takes place. The lower portion 11 has a smaller width than the upper portion 12. Accordingly, the lower portion 11 receives an electric line 3.1 with a predetermined first diameter or cross section and the upper portion 12 an electric line 3.2 with a predetermined second diameter or Cross-section which is greater than that of the electrical line 3.1 in the lower region 11. Between the electrical lines 3.1.3.2 and the areas 11,12 a press fit is provided which can accommodate a predetermined holding force. The higher the interference fit, the higher the holding force that can be received by the strain relief element 7. On the other hand, the interference fit must not be too high to avoid damaging the insulation of the electrical line 3. The electrical lines 3 are arranged in the first recess 8, that their distance from each other is as small as possible, so that the upper electrical line 3 forms a stop for the lower electrical line 3.

Die elektrischen Leitungen 3.1,3.2, die zusammen in der ersten Ausnehmung 8 gelagert sind, können auch über ihre Isolierung fest miteinander verbunden, beispielsweise verschweisst, sein und gemeinsam in die erste Ausnehmung 8 eingeführt und verpresst werden.The electrical lines 3.1.3.2, which are mounted together in the first recess 8, can also be firmly connected to one another via their insulation, for example, welded, and be introduced and pressed together in the first recess 8.

Bei dem zweiten Ausführungsbeispiel ist eine spiegelsymmetrische erste Ausnehmung 8 vorgesehen mit zwei Einführschrägen 9. Es kann aber ausdrücklich auch nur eine einzige Einführschräge 9 ausgebildet sein. Die erste Ausnehmung 8 hat im unteren Bereich 11 eine konstante Breite B1 und im oberen Bereich 12 eine konstante Breite B2, wobei die Breite B1 kleiner ist als die Breite B2. Zwischen den Bereichen 11,12 erfolgt eine kontinuierliche Änderung der Breite von B1 auf B2 bzw. umgekehrt mittels zweier Schrägen 14.In the second embodiment, a mirror-symmetrical first recess 8 is provided with two insertion bevels 9. However, it can expressly be formed only a single insertion bevel 9. The first recess 8 has a constant width B1 in the lower region 11 and a constant width B2 in the upper region 12, the width B1 being smaller than the width B2. Between the regions 11, 12 there is a continuous change of the width from B1 to B2 or vice versa by means of two bevels 14.

Im Unterschied zum zweiten Ausführungsbeispiel hat der untere Bereich 11 und/oder der obere Bereich 12 zumindest eine Vertiefung 16, in die die elektrische Leitung 3.1,3.2 einrastet, so dass diese in Richtung der Längsertreckung der ersten Ausnehmung 8 festgelegt ist. Die Vertiefung 16 ist beispielsweise beidseitig vorgesehen, so dass sich eine spiegelsymmetrische erste Ausnehmung 8 ergibt. Es kann jedoch auch nur eine einzige Vertiefung 16 für einen Bereich 11,12 vorgesehen sein. Die Vertiefung 16 ist nach innen gewölbt ausgeführt.In contrast to the second exemplary embodiment, the lower region 11 and / or the upper region 12 has at least one depression 16 into which the electrical line 3.1, 3.2 engages, so that it is fixed in the direction of the longitudinal extension of the first recess 8. The recess 16 is provided on both sides, for example, so that a mirror-symmetrical first recess 8 results. However, it may also be provided only a single recess 16 for a range 11,12. The recess 16 is executed curved inwards.

Bei der Vorrichtung nach Fig.4 sind die gegenüber der Vorrichtung nach Fig.1 gleichbleibenden oder gleichwirkenden Teile durch die gleichen Bezugszeichen gekennzeichnet.In the device according to Figure 4 are the opposite to the device according to Fig.1 Constant or equivalent parts by the same reference numerals.

Bei dem vierten Ausführungsbeispiel ist die erste Ausnehmung 8 unsymmetrisch ausgebildet. Die Änderung der Breite erfolgt nur einseitig mittels einer einzigen Schräge 14. Auch bei dieser Ausführung kann für die einzelnen Einzeladern 3 eine gewölbte Vertiefung 16 zur Lagefixierung vorgesehen sein.In the fourth embodiment, the first recess 8 is formed asymmetrically. The change in width is only on one side by means of a single slope 14. Also in this embodiment, a curved recess 16 may be provided for fixing the individual veins 3.
