Description

Die Erfindung betrifft eine Schleifleitung, insbesondere eine Kastenschleifleitung, nach dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zum Verbinden von Leiterbänder von benachbarten Teilstücken einer Schleifleitung sowie die Verwendung eines Klemmverbinders zum Verbinden von Leiterbändem von benachbarten Teilstücken einer Schleifleitung.The invention relates to a conductor rail, in particular a box grinding line, according to the preamble of claim 1 and a method for connecting conductor strips of adjacent sections of a conductor rail and the use of a clamp connector for connecting Leiterbändem of adjacent sections of a conductor rail.

Eine Schleifleitung nach dem Oberbegriff des Anspruchs 1 ist aus dem Firmenprospekt der Wampfler AG "Kastenschleifleitungen Programm 0842" und aus DE 102 27 079 bekannt. Die Schleifleitungsteilstücke der darin beschriebenen Kastenschleifleitung können auf verschiedene Arten miteinander verbunden werden. Eine Möglichkeit der Verbindung besteht darin, die in dem Gehäuse der Kastenschleifleitung verlaufenden Leiterbänder an ihrem Ende nach außen um 90° umzubiegen. Die nach außen umgebogenen Enden der Leiterbänder von benachbarten Schleifleitungsteilstücken können dann mit einem Winkelklemmverbinder elektrisch und mechanisch miteinander verbunden werden, der über die quer aus dem Gehäuse vorstehenden und aneinander gefügten Enden der Leiterbänder von benachbarten Schleifleitungsteilstücken geklemmt oder auch geschraubt werden kann.A contact line according to the preamble of claim 1 is known from the company brochure of Wampfler AG "box grinding lines Program 0842" and from DE 102 27 079 known. The slip line sections of the box grinding line described therein may be interconnected in various ways. One possibility of the connection is to bend the conductor strips extending in the housing of the box-type grinding line at their end outwards by 90 °. The outwardly bent ends of the conductor strips of adjacent conductor rail sections can then be electrically and mechanically interconnected with an angle clamp connector that can be clamped or threaded over the transversely projecting and joined ends of the conductor strips of adjacent conductor rail sections.

Diese Art von Verbindung von Schleifleitungsteilstücken erweist sich bei der Montage allerdings als aufwendig. Darüber hinaus gestaltet sich der Transport der noch unmontierten Schleifleitungsteilstücke auf Grund der nach außen abstehenden Enden der Leiterbänder als schwierig und es besteht die Gefahr, dass die abstehenden Leiterbänderenden beim Transport umgebogen werden oder abbrechen.However, this type of connection of conductor rail sections proves to be expensive during assembly. In addition, the transport of the still unmounted Schleifleitungsteilstücke due to the outwardly projecting ends of the conductor strips designed as difficult and there is a risk that the protruding conductor strip ends are bent or broken during transport.

Aus der EP 0 771 999 A2 ist ein Niedervoltstromschienensystem für Leuchten bekannt, welches Niedervoltstromschienen aus zwei parallel zueinander verlaufenden, streifenförmig leitenden Außenschichten und einer zwischen diesen angeordneten Isolierschicht umfasst. Die Verbindung von zwei benachbarten Stromschienen oder der Anschluss von Stromschienen an Anschlussvorrichtungen wird dabei dadurch realisiert, dass die leitenden Außenschichten an den Enden der Stromschienen jeweils um etwa 90° nach außen umgebogen sind, so dass sich an jedem Ende einer Stromschiene zwei Verbindungsflächen ergeben. Diese Verbindungsflächen sind an die entsprechenden Verbindungsflächen einer benachbarten Stromschiene anlegbar, wobei die Verbindungsflächen von miteinander zu verbindenden Stromschienen beispielsweise durch Schrauben und Muttern über geeignete Bohrungen aneinander festlegbar sind. Der Verbindungsbereich von miteinander verbundenen Stromschienen kann durch geeignete Verkleidungskörper umgeben werden.From the EP 0 771 999 A2 a low-voltage busbar system for lighting is known, which comprises low-voltage busbars of two mutually parallel, strip-shaped conducting outer layers and an insulating layer arranged between them. The connection of two adjacent busbars or the connection of busbars to connection devices is thereby realized in that the conductive outer layers are bent at the ends of the busbars in each case by about 90 ° to the outside, so that there are two connecting surfaces at each end of a busbar. These connection surfaces can be applied to the corresponding connection surfaces of an adjacent busbar, wherein the connection surfaces to be connected by each other Busbars, for example, by screws and nuts on suitable holes are fixed to each other. The connection region of interconnected busbars may be surrounded by suitable trim bodies.

Hiervon ausgehend liegt der Erfindung die Aufgabe zu Grunde, eine gattungsgemäße Schleifleitung so zu verbessern, dass eine einfache, manuell durchführbare Verbindung von Schleifleitungsteilstücken unter Verwendung von möglichst wenigen Bauteilen und unter Beibehaltung einer hohen Systemsicherheit möglich wird. Ferner soll der Transport der noch unmontierten Schleifleitungsteilstücke vereinfacht werden. Die Kontaktstelle, an der die Leiterbänder von benachbarten Schleifleitungsteilstücken miteinander verbunden sind, soll möglichst vibrationsfest und elektrisch gut leitend sein.On this basis, the invention is based on the object to improve a generic conductor rail so that a simple, manually feasible connection of Schleifwerksteilstücken using as few components and while maintaining a high level of system security is possible. Furthermore, the transport of the still unmounted Schleifleitungsteilstücke should be simplified. The contact point at which the conductor strips are connected by neighboring Schleifleitungsteilstücke with each other should be as vibration resistant and good electrical conductivity.

Gelöst werden diese Aufgaben mit einer Schleifleitung mit den Merkmalen des Anspruchs 1 sowie einem Verfahren zum Verbinden von Leiterbändern von benachbarten Teilstücken einer Schleifleitung nach Anspruch 7 und der Verwendung eines Klemmverbinders zum Verbinden von Leiterbändern von benachbarten Teilstücken einer Schleifleitung nach Anspruch 8. Bevorzugte Ausgestaltungen der erfindungsgemäßen Schleifleitung sind den Ansprüchen 2 bis 6 zu entnehmen.These objects are achieved with a conductor rail having the features of claim 1 and a method for connecting conductor strips of adjacent sections of a conductor rail according to claim 7 and the use of a clamp connector for connecting conductor strips of adjacent sections of a conductor rail according to claim 8. Preferred embodiments of the invention Conductor line can be found in claims 2 to 6.

Die in den Darstellungen der Figur 1 in einer perspektivischen Ansicht gezeigte Kastenschleifleitung besteht aus mehreren Schleifleitungsteilstücken 1a, 1b, welche an ihren Enden miteinander elektrisch und mechanisch verbunden sind. Die Kastenschleifleitung umfasst ein kastenförmiges Gehäuse 2 aus einem elektrisch isolierenden Material, üblicherweise Kunststoff, und ein oder mehrere in dem Gehäuse verlaufende Leiterbänder 4, 4',6, 6', aus einem elektrisch leitenden Material, beispielsweise aus Kupferband. Die in Figur 1 dargestellte Ausführungsform der erfindungsgemäßen Schleifleitung umfasst zwei Leiterbänder, wobei die in dem Schleifleitungsteilstück 1a verlaufenden Leiterbänder mit den Bezugszahlen 4 und 4' und die in dem Schleifleitungsteilstück 1a verlaufenden Leiterbänder mit den Bezugszeichen 6 und 6' gekennzeichnet sind. An der in Figur 1 perspektivisch dargestellten Kontaktstelle von zwei aufeinander folgenden Schleifleitungsteilstücken 1a, 1b sind die Leiterbänder 4, 4' bzw. 6, 6' an ihren Enden aus dem Gehäuse 2 nach außen um 180° umgebogen. Die nach außen umgebogenen Enden der Leiterbänder 4, 4' und 6, 6' verjüngen sich zu ihrem Ende hin und sind in dem hier zeichnerisch dargestellten Ausführungsbeispiel insbesondere konisch nach hinten spitz zulaufend. Im Bereich der Biegung der Leiterbänder 4, 4' bzw. 6, 6' stoßen die oberen Leiterbänder 4, 6 und die unteren Leiterbänder 4', 6' der beiden Schleifleitungsteilstücke 1a und 1b stirnseitig aneinander. Die Biegung der Leiterbänder bildet dadurch eine Kontaktfläche 5, an der die jeweils zueinander korrespondierenden Leiterbänder 4, 6 und 4', 6' in elektrischem Kontakt miteinander stehen und den Stromfluss von dem Schleifleitungsteilstück 1a zum benachbarten Schleifleitungsteilstück 1b gewährleisten.The in the representations of the FIG. 1 The box grinding line shown in a perspective view consists of a plurality of conductor rail sections 1a, 1b, which are electrically and mechanically connected to one another at their ends. The box grinding line comprises a box-shaped housing 2 of an electrically insulating material, usually plastic, and one or more in the housing extending conductor strips 4, 4 ', 6, 6', made of an electrically conductive material, such as copper tape. In the FIG. 1 illustrated embodiment of the conductor rail according to the invention comprises two conductor strips, wherein in the slip line section 1a extending conductor strips with the reference numbers 4 and 4 'and in the slip line section 1a extending conductor strips with the reference numerals 6 and 6' are marked. At the in FIG. 1 perspectively illustrated contact point of two successive Schleifleitungsteilstücken 1a, 1b, the conductor strips 4, 4 'and 6, 6' at their ends from the housing 2 to the outside by 180 ° bent. The outwardly bent ends of the conductor strips 4, 4 'and 6, 6' taper towards their end and, in the exemplary embodiment illustrated here in the drawing, are in particular conically tapered towards the rear. In the region of the bending of the conductor strips 4, 4 'and 6, 6', the upper conductor strips 4, 6 and the lower conductor strips 4 ', 6' of the two conductor line sections 1a and 1b abut one another at the front. The bending of the conductor strips thereby forms a contact surface 5, at which the respectively mutually corresponding conductor strips 4, 6 and 4 ', 6' are in electrical contact with each other and ensure the flow of current from the conductor rail section 1a to the adjacent conductor rail section 1b.

In Figur 2a ist ein aus einem elektrisch leitfähigen Material hergestellter Klemmverbinder 3 in einer Vorderansicht dargestellt (Figur 2a oben). In der Darstellung darunter ist in einer Seitenansicht die Kontaktstelle der Leiterbänder 4 und 6 der Schleifleitungsteilstücke 1a und 1b gezeigt (Figur 2a unten). Der in Figur 2a oben dargestellte Klemmverbinder 3 besteht aus zwei Flügeln 7, 8 und einem zwischen den beiden Flügeln angeordneten Verformungsbereich 9. Der Verformungsbereich 9 kann aus einem leichter verformbaren Material gebildet sein oder aus demselben Material wie die beiden Flügel 7, 8, jedoch dünner. Die Flügel 7, 8 und der Verformungsbereich 9 können jedoch auch aus demselben und gleich dicken Material gebildet werden. Der Verformungsbereich 9 ist durch Falze oder Biegelinien von den Flügeln 7, 8 abgegrenzt. In Figur 1c ist der Klemmverbinder 3 in einer perspektivischen Ansicht gezeigt und es ist zu sehen, dass der Verformungsbereich 9 gegenüber den Flügeln 7, 8 hochgebogen ist und aus der Ebene der Flügel 7, 8 vorsteht.In FIG. 2a a clamp connector 3 produced from an electrically conductive material is shown in a front view ( FIG. 2a above). In the illustration below, the contact point of the conductor strips 4 and 6 of the conductor rail sections 1a and 1b is shown in a side view ( FIG. 2a below). The in FIG. 2a Clamping connector 3 shown above consists of two wings 7, 8 and a deformation area 9 arranged between the two wings. The deformation area 9 can be formed of a material which deforms more easily or can be made of the same material as the two wings 7, 8, but thinner. However, the wings 7, 8 and the deformation region 9 can also from the same and the same thickness material be formed. The deformation region 9 is delimited by folds or bending lines of the wings 7, 8. In Figure 1c the clamping connector 3 is shown in a perspective view and it can be seen that the deformation region 9 is bent upwards relative to the wings 7, 8 and protrudes from the plane of the wings 7, 8.

Zum Verbinden der Enden der Leiterbänder 4, 6 bzw. 4', 6' von benachbarten Schleifleitungsteilstücken 1a, 1b wird der Klemmverbinder 3 zunächst wie in Figur 2b gezeigt mit einem Flügel 7 über ein umgebogenes Ende eines Leitungsbandes 4 geschoben. Damit der Flügel 7 des Klemmverbinders 3 das Ende des Leiterbandes 4 umgreifen kann sind auf der Innenseite des Klemmverbinders 3 an jedem Flügel 7, 8 Umgreiflaschen 10 vorgesehen. Der Klemmverbinder 3 kann somit über das Ende eines Leiterbandes 4 geschoben werden und die Umgreiflaschen 10 umschließen das Ende des Leiterbandes 4 und stellen eine Klemmverbindung zum Leiterband 4 her. Anschließend wird der Klemmverbinder 3 zunächst leicht in Längsrichtung auf das benachbarte Schleifleitungsteilstück 1b hin gezogen und der zweite Flügel 8, der ebenfalls über eine Umgreiflasche 10 verfügt, wird über das nach außen umgebogene Ende des korrespondieren Leiterbandes 6 geschoben. Auf Grund der Flexibilität und der federnden Eigenschaften insbesondere des Verformungsbereichs 9 des Klemmverbinders 3 zieht dieser sich in seine Ursprungsform zurück. In Figur 1b ist die Kontaktstelle der beiden Schleifleitungsteilstücke 1a und 1b in diesem Stadium des erfindungsgemäßen Verfahrens gezeigt. Zur Verfestigung der Verbindung und zur Herstellung eines elektrischen Kontakts zwischen den korrespondierenden Leiterbändern, 4, 6 und 4', 6' wird der Klemmverbinder 3 im Verformungsbereich 9 mittels einer Zange oder eines anderen Verformwerkzeugs zusammengedrückt, wie in Figur 1c dargestellt. Durch das Zusammendrücken des Klemmverbinders 3 zieht sich der Klemmverbinder 3 in seiner Längsrichtung zusammen und drückt dabei die in seinen Flügeln 7, 8 eingeschobenen Enden der Leiterbänder 4, 6 bzw. 4', 6' aneinander. Auf Grund der sich nach außen verjüngenden Enden der Leiterbänder 4, 6 bzw. 4', 6' wird der Klemmverbinder 3 beim Zusammendrücken des Verformungsbereichs 9 weiter in die Enden der Leiterbänder 4, 6 bzw. 4', 6' geschoben. Die Form der Flügel 7, 8 des Klemmverbinders 3 ist der Form der Enden der Leiterbänder 4, 6 angepasst, so dass beim Zusammendrücken des Verformungsbereichs des Klemmverbinders 3 gleichzeitig auch die Leiterbänder 4, 6 bzw. 4', 6' im Bereich ihrer Biegung stirnseitig zur Bildung einer Kontaktfläche 5 aneinander gedrückt werden. In Figur 1d ist die Kontaktstelle der Schleifleitungsteilstücke 1a, 1b mit den durch die Klemmverbinder 3 aneinander gedrückten Leiterbänder 4, 6 bzw. 4', 6' gezeigt. Figur 2c zeigt diese Kontaktstelle mit der Kontaktfläche 5 in einer Seitenansicht von innen gesehen.For connecting the ends of the conductor strips 4, 6 and 4 ', 6' of adjacent sliding line sections 1a, 1b, the clamping connector 3 is first as in FIG. 2b shown with a wing 7 pushed over a bent end of a conduction band 4. Thus, the wing 7 of the clamp connector 3 can embrace the end of the conductor strip 4 are provided on the inside of the clamp connector 3 on each wing 7, 8 Umgreiflaschen 10. The clamping connector 3 can thus be pushed over the end of a conductor strip 4 and the Umgreiflaschen 10 enclose the end of the conductor strip 4 and provide a clamping connection to the conductor strip 4 ago. Subsequently, the clamp connector 3 is first slightly pulled in the longitudinal direction of the adjacent slip line section 1b and the second wing 8, which also has a Umgreiflasche 10 is pushed over the bent-out end of the corresponding conductor strip 6. Due to the flexibility and the resilient properties, in particular of the deformation region 9 of the clamp connector 3, this pulls back into its original shape. In FIG. 1b the contact point of the two sliding line sections 1a and 1b is shown at this stage of the method according to the invention. To consolidate the connection and to produce an electrical contact between the corresponding conductor strips, 4, 6 and 4 ', 6', the clamping connector 3 is compressed in the deformation region 9 by means of a pliers or other deformation tool, as in Figure 1c shown. By compressing the clamping connector 3, the clamping connector 3 contracts in its longitudinal direction and presses the inserted in its wings 7, 8 ends of the conductor strips 4, 6 and 4 ', 6' to each other. Due to the outwardly tapered ends of the conductor strips 4, 6 and 4 ', 6' of the clamping connector 3 is further pushed in compressing the deformation region 9 in the ends of the conductor strips 4, 6 and 4 ', 6'. The shape of the wings 7, 8 of the terminal connector 3 is adapted to the shape of the ends of the conductor strips 4, 6, so that when compressing the deformation region of the terminal connector 3 at the same time, the conductor strips 4, 6 and 4 ', 6' in the region of their bending frontally to form a contact surface 5 are pressed against each other. In Figure 1d is the contact point of the sliding line sections 1a, 1b with each other through the clamp connector 3 pressed conductor strips 4, 6 and 4 ', 6' shown. Figure 2c shows this contact point with the contact surface 5 in a side view seen from the inside.

Durch die erfindungsgemäße Verbindung der Leiterbänder von benachbarten Schleifleitungsteilstücken ist eine elektrisch gut leitende Verbindung der Leiterbänder unter einer definierten Klemm- und Kontaktkraft gewährleistet. Die Handhabung des Klemmverbinders ist sehr einfach und es werden nur wenige Bauteile, nämlich lediglich der Klemmverbinder 3, zur Herstellung der Verbindung benötigt. Die Montage ist unter Zuhilfenahme eines Klemmwerkzeugs auch mit einer Hand möglich. Darüber hinaus ist der Transport der noch unmontierten Schleifleitungsteilstücke 1a, 1b unproblematisch, da die Enden der Leiterbänder nicht wie beim Stand der Technik rechtwinklig nach außen vom Gehäuse überstehen sondern um 180° umgebogen sind. Der Klemmverbinder ermöglicht ferner auch eine einfache Demontage der Schleifleitungsteilstücke, da der zusammengedrückte Klemmverbinder auch wieder ohne Probleme auseinander gezogen und von den umgebogenen Enden der Leiterbänder abgezogen werden kann.The connection according to the invention of the conductor strips of adjacent conductor rail sections ensures an electrically good conductive connection of the conductor strips under a defined clamping and contact force. The handling of the terminal connector is very simple and there are only a few components, namely only the terminal connector 3, needed to make the connection. The assembly is possible with the aid of a clamping tool with one hand. In addition, the transport of the still unmounted sliding line sections 1a, 1b is unproblematic, since the ends of the conductor strips are not projecting at right angles to the outside of the housing as in the prior art but are bent by 180 °. The clamp connector also allows easy disassembly of the sliding line sections, since the compressed clamp connector can be pulled apart again without problems and withdrawn from the bent ends of the conductor strips.
