Definitions
- the invention relates to screwable fasteners such as screws or nuts, with the help of which releasable electrical connections are made by using these fasteners a cable lug, which in turn is connected to an electrically conductive cable, in close, electrically conductive contact with another metallic object brought.
- This technology is not only used for switching elements in the high-voltage area, but also, for example, in motor vehicle construction, where the body of the vehicle forms the negative pole of the circuit due to the DC power supply, and a large number of cables must be connected to the body in an electrically conductive manner.
- the cable lug which is permanently attached to the cable and whose contact plate has a hole, is either placed over the threaded bolt that protrudes from the body and secured with a nut, or a screw is inserted through the hole in the contact plate and the screw is screwed in to screw their threaded part in a corresponding internal thread of the body, or to push it through a further hole in the body, and to secure it with a nut on the back of the body panel.
- the object of the invention is to design the individual parts concerned in such a way that a faster and more error-free assembly of the cable lug and thus the electrical connection is ensured.
- the fastening element is a screw
- this non-detachable but rotatable connection between the cable lug and the screw is achieved in a simple manner, for example, in that the contact plate of the cable lug is rotatably mounted with its bore on the outer diameter of a shaft region 14, which is located between the head 3 and the threaded area 13 of the screw 2 and wherein the bore of the contact plate has a smaller diameter than the outer diameter of the threaded area and also the head of the screw.
- connection e.g. can be selected when using a nut as a fastening element is that the nut or the head of a screw adjacent to the end face directed against the main part has a region of a greatly reduced outer diameter.
- the contact plate of the cable lug with the inwardly directed lateral surfaces of the bore is rotatably but not detachably supported by one element having an annular circumferential groove and the other element an encircling groove engaging in this groove Ring bead or several individual projections distributed over the circumference.
- the axial dimensioning is selected so that the axial length of the shoulder with a reduced diameter of the nut or the head of the screw is at most as large, preferably slightly less, than the thickness of the contact plate. This ensures that after screwing the nut or screw, the nut or head of the screw presses against the contact plate of the cable lug, and only the contact plate of the cable lug bears against the main part, but not the mother herself with her directed against the main part Face in the area of the reduced diameter.
- Adequate storage could, however, also be carried out in the area of the inner circumference of the through hole of the nut, into which a corresponding flange area of the contact plate protrude would have to be, in which case the inner diameter in the mother would have to be larger than the internal thread of the mother, and this bearing would also have to be adjacent to the front contact surface of the mother.
- Figure 1 first shows a cable lug 5 which - as is generally known - is connected to the stripped end of the cable 6 by pressing the clamping part 18 of the cable lug with the cable 6.
- the contact plate 8 of the cable lug 5 strives from the clamping part 18, the clamping part being 18 and the cable 6 are usually located as shown above the underside 16 of the contact plate 8, which is to be brought into the electrically conductive with the main part, not shown, for example the sheet metal of a car body.
- the nut 1 With the contact plate 8 of the cable lug 5, the nut 1 is rotatably but non-detachably connected, in that the nut 1 has a shoulder with a greatly reduced outside diameter, in which an annular circumferential groove 11 is formed, in relation to the main part, on its normal, front-side contact surface 4.
- the contact plate 8 with its bore 9 is rotatably mounted on the greatly reduced outer diameter, the inner wall of the bore 9 not being cylindrical, but having an annular circumferential projection 12 which engages in the groove 11, and due to the existing play allows rotation between the nut 1 and the contact plate 8, but not their separation, for example in the axial direction.
- the axial length of the area of the nut 1 with a greatly reduced outer diameter is less than the thickness of the contact plate 8 in this area, so that in the assembled state, that is to say screwed to the main part, only the contact plate 8 with its underside 16 rests on the corresponding opposite side of the main part, but not the nut 1 with its end face 4, since otherwise the necessary pressure of the nut 1 against the top of the contact plate 8 and thus also the necessary pressure between the underside 16 of the contact plate 8 and the main part, not shown, would not be given.
- FIG. 3 shows the connection of an analog cable lug 5 with a screw 2, as is used when there is not a fixed threaded bolt on the main part, but only a through hole with or without an internal thread.
- the contact plate 8 of the cable lug 5 is mounted with its bore 9 between the head 3, which has a larger diameter than the shaft, and a thickening in the shaft area.
- This thickening is usually the threaded area 13, which extends to the free end of the shaft while extending between it Thread region 13 and the head 3 is a shaft region 14 without an external thread, the axial length of which corresponds at least to the thickness of the contact plate 8.
- the diameter of the bore 9 in the contact plate 8 is larger than the outer diameter in the shaft region 14, but smaller than the outer diameter in the threaded region 13, the contact plate 8 can rotate freely about the longitudinal axis 7 of the screw 2, but not of the screw 2 subtracted from.
- the advantage in all these cases is that the operator only has to grasp and screw the screw or nut, for example with the aid of his screwing tool, but not additionally the cable lug, since this is undetachable with the nut 1 or with the screw 2 is connected.
- annular or radial projections 17 can be arranged striving downwards in order to press the underside 16 of the contact plate 8 to produce an intimate, reliably electrically conductive contact with the main part, not shown, even if this main part should already be painted.

Abstract
Description
Die Erfindung betrifft verschraubbare Befestigungselemente wie Schrauben oder Muttern, mit deren Hilfe auch lösbare, elektrische Verbindungen hergestellt werden, indem mit Hilfe dieser Befestigungselemente ein Kabelschuh, der seinerseits mit einem elektrisch leitenden Kabel verbunden ist, in engen, elektrisch leitenden Kontakt mit einem anderen metallischen Gegenstand gebracht wird.The invention relates to screwable fasteners such as screws or nuts, with the help of which releasable electrical connections are made by using these fasteners a cable lug, which in turn is connected to an electrically conductive cable, in close, electrically conductive contact with another metallic object brought.
Diese Technik wird nicht nur für Schaltelemente im Starkstrombereich angewendet, sondern beispielsweise auch im Kfz-Bau, wo wegen der Gleichstromversorgung die Karosserie des Fahrzeuges den Minuspol des Stromkreises bildet, und damit eine Vielzahl von Kabeln elektrisch leitend mit der Karosserie verbunden werden müssen.This technology is not only used for switching elements in the high-voltage area, but also, for example, in motor vehicle construction, where the body of the vehicle forms the negative pole of the circuit due to the DC power supply, and a large number of cables must be connected to the body in an electrically conductive manner.
Dabei ist es bekannt, den am Kabel unlösbar befestigten Kabelschuh, dessen Kontaktplatte eine Bohrung aufweist, entweder über den fest aus der Karosserie aufragenden Gewindebolzen zu stülpen und mit einer Mutter zu sichern, oder eine Schraube durch die Bohrung der Kontaktplatte zu stecken und die Schraube mit ihrem Gewindeteil in einem entsprechenden Innengewinde der Karosserie zu verschrauben, bzw. durch eine weitere Bohrung in der Karosserie hindurchzustecken, und mit einer Mutter auf der Rückseite des Karosseriebleches zu sichern.It is known that the cable lug, which is permanently attached to the cable and whose contact plate has a hole, is either placed over the threaded bolt that protrudes from the body and secured with a nut, or a screw is inserted through the hole in the contact plate and the screw is screwed in to screw their threaded part in a corresponding internal thread of the body, or to push it through a further hole in the body, and to secure it with a nut on the back of the body panel.
Dabei besteht das Problem darin, daß das Montagepersonal immer mit der einen Hand den Kabelschuh ergreifen muß, und mit der anderen Hand das benötigte Befestigungselement, also Schraube oder Mutter, und auf diese Art und Weise häufig eine dritte Hand fehlt, um weitere Teile positionieren oder festhalten zu können. Zusätzlich besteht das Risiko darin, daß aus den bevorrateten Schrauben und Muttern am Montageplatz die falsche gegriffen wird und damit eine Montage zunächst nicht möglich ist, oder aber aufgrund falscher Länge der Schraube etc. kein ausreichend sicherer elektrischer Kontakt trotz mechanisch ausreichender Befestigung des Kabelschuhes gegeben ist. Beides zusammen führt zu erhöhten Montagezeiten bzw. Nacharbeitszeiten.The problem is that the assembly personnel must always take the cable lug with one hand, and with the other hand the required fastening element, i.e. screw or nut, and in this way a third hand is often missing in order to position further parts or to be able to hold on. In addition, there is a risk that from the stored screws and Nuts at the assembly site are gripped incorrectly and assembly is initially not possible, or due to the incorrect length of the screw etc. there is no sufficiently secure electrical contact despite mechanically sufficient fastening of the cable lug. Both together lead to increased assembly times or rework times.
Um die Montagezeit und Fehleranfälligkeit von Kraftfahrzeugen zu verringern, besteht die Aufgabe der Erfindung darin, die betroffenen Einzelteile so auszubilden, daß eine schnellere und fehlerfreiere Montage des Kabelschuhs und damit der elektrischen Verbindung gewährleistet ist.In order to reduce the assembly time and susceptibility to errors of motor vehicles, the object of the invention is to design the individual parts concerned in such a way that a faster and more error-free assembly of the cable lug and thus the electrical connection is ensured.
Diese Aufgabe wird dadurch gelöst, daß die Mutter bzw. Schraube mit der Kontaktplatte des Kabelschuhs nicht lösbar und damit unverlierbar verbunden ist. Lediglich die Drehung der Schraube bzw. Mutter gegenüber der Kontaktplatte, wie sie für das Verschrauben notwendig ist, ist möglich.This object is achieved in that the nut or screw is not detachably and thus captively connected to the contact plate of the cable lug. Only the rotation of the screw or nut relative to the contact plate, as is necessary for screwing, is possible.
Handelt es sich bei dem Befestigungselement um eine Schraube, wird diese unlösbare, jedoch drehbare Verbindung zwischen dem Kabelschuh und der Schraube auf einfache Art und Weise etwa dadurch erreicht, daß die Kontaktplatte des Kabelschuhs mit ihrer Bohrung auf dem Außendurchmesser eines Schaftbereiches 14 drehbar gelagert ist, der sich zwischen dem Kopf 3 und dem Gewindebereich 13 der Schraube 2 befindet und wobei die Bohrung der Kontaktplatte einen kleineren Durchmesser hat, als der Außendurchmesser des Gewindebereiches und auch der Kopf der Schraube.If the fastening element is a screw, this non-detachable but rotatable connection between the cable lug and the screw is achieved in a simple manner, for example, in that the contact plate of the cable lug is rotatably mounted with its bore on the outer diameter of a
Dies kann bei der Herstellung erreicht werden, indem die Kontaktplatte auf den Schaftbereich der Schraube aufgeschoben wird, bevor im Gewindebereich das Außengewinde der Schraube mittels Gewinderollen hergestellt wird, wodurch erst der Außendurchmesser im Gewindebereich so stark vergrößert wird, daß er größer ist als der Innenbereich der Bohrung der Kontaktplatte.This can be achieved during manufacture by pushing the contact plate onto the shaft area of the screw before the external thread of the screw is used in the threaded area by means of thread rolls is produced, whereby only the outer diameter in the threaded area is increased so much that it is larger than the inner area of the bore of the contact plate.
Eine andere Möglichkeit der Verbindung, wie sie z.B. bei Verwendung einer Mutter als Befestigungselement gewählt werden kann, besteht darin, daß die Mutter oder auch der Kopf einer Schraube angrenzend an die gegen das Hauptteil gerichtete Stirnfläche einen Bereich eines stark verringerten Außendurchmessers aufweist. In dem dadurch entstehenden Absatz ist beispielsweise auf dem verringerten Außendurchmesser die Kontaktplatte des Kabelschuhs mit den nach innen gerichteten Mantelflächen der Bohrung drehbar, aber nicht lösbar gelagert, indem das eine Element eine ringförmig umlaufende Nut aufweist, und das andere Element eine in diese Nut eingreifende umlaufende Ringwulst oder auch mehrere, über den Umfang verteilte einzelne Vorsprünge.Another possibility of connection, e.g. can be selected when using a nut as a fastening element is that the nut or the head of a screw adjacent to the end face directed against the main part has a region of a greatly reduced outer diameter. In the resulting paragraph, for example, on the reduced outer diameter, the contact plate of the cable lug with the inwardly directed lateral surfaces of the bore is rotatably but not detachably supported by one element having an annular circumferential groove and the other element an encircling groove engaging in this groove Ring bead or several individual projections distributed over the circumference.
Dabei ist es wichtig, daß die axiale Dimensionierung so gewählt ist, daß die axiale Länge des Absatzes mit verringertem Durchmesser der Mutter bzw. des Kopfes der Schraube maximal so groß, vorzugsweise etwas geringer, ist als die Dicke der Kontaktplatte. Dadurch ist sichergestellt, daß nach dem Verschrauben der Mutter bzw. der Schraube die Mutter bzw. der Kopf der Schraube gegen die Kontaktplatte des Kabelschuhs drückt, und ausschließlich die Kontaktplatte des Kabelschuhs am Hauptteil anliegt, nicht jedoch die Mutter selbst mit ihrer gegen das Hauptteil gerichteteten Stirnfläche im Bereich des verringerten Durchmessers.It is important that the axial dimensioning is selected so that the axial length of the shoulder with a reduced diameter of the nut or the head of the screw is at most as large, preferably slightly less, than the thickness of the contact plate. This ensures that after screwing the nut or screw, the nut or head of the screw presses against the contact plate of the cable lug, and only the contact plate of the cable lug bears against the main part, but not the mother herself with her directed against the main part Face in the area of the reduced diameter.
Eine adäquate Lagerung könnte jedoch ebenfalls im Bereich des Innenumfanges der Durchgangsbohrung der Mutter vollzogen werden, in welchen ein entsprechender Flanschbereich der Kontaktplatte hineinragen müßte, wobei dann der Innendurchmesser in der Mutter größer sein müßte als das Innengewinde der Mutter, und diese Lagerung ebenfalls benachbart an die stirnseitige Kontaktfläche der Mutter anschließen müßte.Adequate storage could, however, also be carried out in the area of the inner circumference of the through hole of the nut, into which a corresponding flange area of the contact plate protrude would have to be, in which case the inner diameter in the mother would have to be larger than the internal thread of the mother, and this bearing would also have to be adjacent to the front contact surface of the mother.

Figur 1 zeigt zunächst einen Kabelschuh 5 der - wie allgemein bekannt - mit dem abisolierten Ende des Kabels 6 verbunden ist durch Verpressen des Klemmteiles 18 des Kabelschuhs mit dem Kabel 6. Vom Klemmteil 18 strebt die Kontaktplatte 8 des Kabelschuhs 5 ab, wobei sich das Klemmteil 18 und das Kabel 6 in der Regel wie dargestellt oberhalb der Unterseite 16 der Kontaktplatte 8 befinden, welche in elektrisch leitenden mit dem nicht dargestellten Hauptteil, beispielsweise dem Blech einer Autokarosserie, gebracht werden soll.Figure 1 first shows a
Mit der Kontaktplatte 8 des Kabelschuhs 5 ist die Mutter 1 drehbar, aber unlösbar verbunden, indem die Mutter 1 anschließend an ihre normale, stirnseitige Anlagefläche 4 gegenüber dem Hauptteil einen Absatz mit stark verringertem Außendurchmesser aufweist, in welchem eine ringförmig umlaufende Nut 11 ausgebildet ist.With the contact plate 8 of the
In dem Absatz ist auf dem stark verringerten Außendurchmesser die Kontaktplatte 8 mit ihrer Bohrung 9 drehbar gelagert, wobei die Innenwandung der Bohrung 9 nicht zylindrisch ausgebildet ist, sondern einen ringförmig umlaufenden Vorsprung 12 aufweist, der in die Nut 11 eingreift, und aufgrund des vorhandenen Spieles zwar eine Drehung zwischen der Mutter 1 und der Kontaktplatte 8 zuläßt, jedoch nicht deren Trennung z.B. in axialer Richtung.In the paragraph, the contact plate 8 with its bore 9 is rotatably mounted on the greatly reduced outer diameter, the inner wall of the bore 9 not being cylindrical, but having an annular
Dabei ist es wichtig, daß die im montierten Zustand die axiale Länge des Bereiches der Mutter 1 mit stark verringertem Außendurchmesser geringer ist als die Dicke der Kontaktplatte 8 in diesem Bereich, damit im montierten, also mit dem Hauptteil verschraubten, Zustand lediglich die Kontaktplatte 8 mit ihrer Unterseite 16 an der entsprechenden Gegenseite des Hauptteiles anliegt, nicht jedoch die Mutter 1 mit ihrer stirnseitigen Anlagefläche 4, da ansonsten die notwendige Pressung der Mutter 1 gegen die Oberseite der Kontaktplatte 8 und damit auch die notwendige Pressung zwischen der Unterseite 16 der Kontaktplatte 8 und dem nicht dargestellten Hauptteil nicht gegeben wäre.It is important that in the assembled state the axial length of the area of the
Figur 3 zeigt demgegenüber die Verbindung eines analogen Kabelschuhs 5 mit einer Schraube 2, wie sie Verwendung findet, wenn am Hauptteil nicht ein feststehender Gewindebolzen, sondern lediglich eine Durchgangsbohrung mit oder ohne Innengewinde vorhanden ist.FIG. 3, on the other hand, shows the connection of an
In diesem Fall wird die Kontaktplatte 8 des Kabelschuhs 5 mit ihrer Bohrung 9 zwischen dem Kopf 3, der einen größeren Durchmesser als der Schaft aufweist, und einer Verdickung im Schaftbereich gelagert. Diese Verdickung ist in der Regel der Gewindebereich 13, der sich bis zum freien Ende des Schaftes erstreckt, während sich zwischen diesem Gewindebereich 13 und dem Kopf 3 ein Schaftbereich 14 ohne Außengewinde befindet, dessen axiale Länge wenigstens der Dicke der Kontaktplatte 8 entspricht. Wenn der Durchmesser der Bohrung 9 in der Kontaktplatte 8 zwar größer als der Außendurchmesser im Schaftbereich 14, jedoch kleiner als der Außendurchmesser im Gewindebereich 13 ist, kann die Kontaktplatte 8 zwar frei um die Längsachse 7 der Schraube 2 drehen, jedoch von der Schraube 2 nicht abgezogen werden. Der Vorteil in all diesen Fällen liegt darin, daß der Bediener lediglich die Schraube bzw. Mutter, beispielsweise mit Hilfe seines Schraubwerkzeuges, erfassen und in Position bringen muß, jedoch nicht zusätzlich den Kabelschuh, da dieser unlösbar mit der Mutter 1 bzw. mit der Schraube 2 verbunden ist.In this case, the contact plate 8 of the
Wie weiterhin in Figur 3 dargestellt, können auf der Unterseite 16 der Kontaktplatte 8, vorzugsweise im Bereich des Kopfes 3 der Schraube 2, einzelne oder auch ringförmige bzw. radiale Vorsprünge 17 nach unten abstrebend angeordnet sein, um bei Anpressung dieser Unterseite 16 der Kontaktplatte 8 gegenüber das nicht dargestellte Hauptteil einen innigen, zuverlässig elektrisch leitenden Kontakt herzustellen, selbst wenn dieses Hauptteil bereits lackiert sein sollte.As further shown in FIG. 3, on the
