Description

Die Erfindung betrifft eine elektrische Vorrichtung mit Schraubklemme zum Anschluss oder Verbinden von elektrischen Leitern.The invention relates to an electrical device with screw terminal for connecting or connecting electrical conductors.

Schraubklemmen, die an der Innenseite ihres Schraubenschachts Vorsprünge in Gestalt von Wülsten oder Rippen aufweisen, so dass eine in den Schraubenschacht eingebrachte Schraube gegen ein unbeabsichtigtes Lösen aus dem Schraubenschacht gesichert ist, sind grundsätzlich bekannt. Diese Sicherung wird dadurch erreicht, dass die Vorsprünge den Innendurchmesser des Schraubenschachts reduzieren, so dass der Schraubenkopf einer eingesetzten Schraube auf die Vorsprünge eine radiale Druckkraft ausübt. Dadurch wird der Schraubenkopf kraftschlüssig gehalten.Screw terminals, which have projections in the form of beads or ribs on the inside of their screw shaft, so that a screw inserted into the screw shaft is secured against unintentional release from the screw shaft are known in principle. This securing is achieved in that the projections reduce the inner diameter of the screw shaft, so that the screw head of an inserted screw exerts a radial compressive force on the projections. As a result, the screw head is frictionally held.

Die durch den Schraubenkopf ausgeübten radialen Druckkräfte führen je nach Ausführung zu einer mehr oder weniger starken Deformation der Gehäusebereiche, die den Schraubenschacht umgeben. Dies erschwert beispielsweise ein passgenaues Einfügen der Schraubklemme in eine andere Anordnung. Es sind verschiedene Lösungen bekannt, die die Druckkräfte teilweise auffangen und somit die Deformationen reduzieren. So ist beispielsweise aus der DE 1972344 ein Schraubenschacht bekannt, der zur Reduzierung von Deformationen und Materialspannungen mit Durchbrüchen im Schraubenschacht versehen ist.Depending on the design, the radial pressure forces exerted by the screw head result in a more or less pronounced deformation of the housing areas surrounding the screw shaft. This complicates, for example, a fitting insertion of the screw in another arrangement. Various solutions are known which partially absorb the pressure forces and thus reduce the deformations. For example, from the DE 1972344 a screw shaft known which is provided to reduce deformation and material stresses with openings in the screw shaft.

Von besonders hoher Bedeutung sind die Deformationen und Materialspannungen bei Schraubklemmen mit mehreren, nebeneinander liegenden Schraubenschächten. Bei ihnen können sich die Druckkräfte respektive Deformationen und Materialspannungen in Anreihrichtung aufsummieren - sie werden also vervielfacht. Um bei solchen Schraubklemmen nachteilige Wirkungen der Druckkräfte einzuschränken, sind Lösungen bekannt, bei denen die Schraubenschächte durch zylinderische Schraubeneinführungskanäle verlängert werden. Diese Einführungskanäle ragen über die Oberseite des Grundgehäuses hinaus. Insbesondere, wenn sich die eingangs genannten Erhebungen ausschließlich an der Innenseite der Einführungskanäle befinden, bewirken die Druckkräfte allenfalls eine Deformation des Einführungskanals, das Grundgehäuse hingegen bleibt weitgehend formstabil. Eine solche Schraubklemme offenbart beispielsweise die GB 903223 .Of particular importance are the deformations and material stresses in screw terminals with several, adjacent screw shafts. With them, the compressive forces or deformations and material stresses in the direction of arrangement can add up - they are multiplied. In order to limit adverse effects of the compressive forces in such screw terminals, solutions are known in which the screw shafts are extended by zylinderische Schraubeneinführungskanäle. These introducer channels protrude beyond the top of the base housing. In particular, if the surveys mentioned above are located exclusively on the inside of the introduction channels, the pressure forces cause at most a deformation of the introduction channel, the base housing, however, remains largely dimensionally stable. Such a screw clamp discloses, for example, the GB 903223 ,

Die Entgegenhaltung DE 297 14 690 U1 zeigt eine als Schraubklemme ausgebildete Anschlussklemme, umfassend ein Gehäuse mit einer Ober- und Unterseite und wenigstens zwei in dem Gehäuse nebeneinander angeordneten Schraubenschächten, wobei die Schraubenschächte jeweils eine Schraubenzuführöffnung auf der Oberseite aufweisen und sich in Richtung der Unterseite erstrecken, die Schraubenzuführöffnung auf einem Niveau mit der übrigen Oberseite des Gehäuses ist, ein Übergangsbereich die Schraubenschächte miteinander verbindet, Erhebungen an der Innenseite der Schraubenschächte angeordnet sind und die Erhebungen von der Unterseite aus betrachtet an oder unterhalb des Niveaus der Oberseite des Übergangsbereichs enden.The citation DE 297 14 690 U1 shows a terminal formed as a screw terminal, comprising a housing having a top and bottom and at least two juxtaposed in the housing screw shafts, wherein the screw wells each have a Schraubenzuführöffnung on the top and extending in the direction of the underside, the Schraubenzuführöffnung on a level the remaining top of the housing is, a transition region, the screw shafts interconnects, elevations are arranged on the inside of the screw shafts and the elevations viewed from the bottom at or below the level of the End of the transition area.

Der Erfindung die Aufgabe zu Grunde, eine flachere Schraubklemme mit Erhebungen an der Innenseite ihres Schraubenschachts zu entwickeln.The invention is based on the object to develop a flatter screw with surveys on the inside of its screw shaft.

Diese Aufgabe wird durch die Merkmale der elektrischen Vorrichtung des Anspruchs 1 gelost.This object is achieved by the features of the electrical device of claim 1.

Die erfindungsgemäße elektrische Vorrichtung mit einer Schraubklemme zum Anschluss oder Verbinden von elektrischen Leitern, umfasst ein Gehäuse mit einer Ober- und Unterseite und wenigstens zwei in dem Gehäuse nebeneinander angeordneten Schraubenschächten, wobei

  • die Schraubenschächte jeweils eine Schraubenzuführöffnung auf der Oberseite aufweisen und sich in Richtung der Unterseite erstrecken,
  • ein Übergangsbereich die Schraubenschächte miteinander verbindet und
  • Erhebungen an der Innenseite der Schraubenschächte angeordnet sind,
    wobei
  • die Erhebungen von der Unterseite aus betrachtet an oder unterhalb des Niveaus der Oberseite des ÜbergangsbeÜbergangsbereichs enden und
  • die Erhebungen ausschließlich außerhalb des Übergangsbereichs angeordnet sind oder zumindest eine erste Erhebung außerhalb des Übergangsbereichs und eine zweite Erhebung innerhalb des Übergangsbereichs vorgesehen sind, wobei die radiale Erstreckung der zweiten Erhebung kleiner ist als die der ersten Erhebung.
The electrical device according to the invention with a screw terminal for connecting or connecting electrical conductors, comprises a housing with a top and bottom and at least two screw shafts arranged side by side in the housing, wherein
  • the screw shafts each have a screw feed opening on the upper side and extend in the direction of the lower side,
  • a transition region connecting the screw shafts and
  • Elevations are arranged on the inside of the screw shafts,
    in which
  • the bumps terminate at or below the level of the top of the transitional transition region when viewed from the bottom
  • the elevations are arranged exclusively outside the transition area or at least a first elevation outside the transition area and a second elevation within the transition area are provided, wherein the radial extent of the second elevation is smaller than that of the first elevation.

Da sich die Erhebungen im Schraubenschacht von der Unterseite aus betrachtet nicht oberhalb des Niveaus der Oberseite des Übergangsbereichs erstrecken, kann eine Verlängerung der Schraubenschächte oberhalb der Oberseite des Übergangsbereichs reduziert werden oder sogar ganz entfallen. Dadurch wird die Schraubklemme insgesamt flacher. Eine flachere Schraubklemme hat den Vorteil, den Anforderungen zunehmender Miniaturisierung im Gerätebau gerecht zu werden. Sie ist insbesondere für solche Anwendungen geeignet, die durch geringe Bauhöhen gekennzeichnet sind. Dies ist beispielsweise in Gerätegehäusen oder Schaltschränken der Fall.
Wird auf die Verlängerung der Schraubenschächte oberhalb des Niveaus der Oberseite des Übergangsbereichs ganz verzichtet, ist die gesamte Oberseite des Gehäuses der Schaubklemme ebenmäßig plan, ohne Erhebungen. Ein Gehäuse mit einer planen Oberseite hat den Vorteil, dass es sich einfacher und schonender entformen lässt. Dadurch reduzieren sich die Fertigungskosten und das Gehäuse wird in der Herstellung weniger mechanisch belastet. Zudem lässt sich eine solche Schraubklemme besser montieren und demontieren, weil die Schraubklemme nicht mit über die Oberseite hinaus ragenden Schraubenschächten hängen bleiben kann.Since the elevations in the screw shaft viewed from the bottom not above the level of the top extend the transition region, an extension of the screw shafts above the top of the transition region can be reduced or even eliminated altogether. As a result, the screw terminal is flatter overall. A flatter screw terminal has the advantage of meeting the requirements of increasing miniaturization in device construction. It is particularly suitable for applications that are characterized by low heights. This is the case, for example, in device housings or control cabinets.
If the extension of the screw shafts above the level of the upper side of the transitional area is completely dispensed with, the entire upper side of the housing of the Schaubklemme is evenly flat, without elevations. A housing with a flat top has the advantage that it can be removed easier and gentler. This reduces the manufacturing costs and the housing is subjected to less mechanical stress in the production. In addition, such a screw can be better assemble and disassemble, because the screw can not hang with protruding beyond the top screw wells.

Dadurch, dass sich im Übergangsbereich keine Erhebungen im Schraubenschacht befinden oder wenn, dann mit kleinerer radialer Erstreckung als andere Erhebungen außerhalb des Übergangsbereichs, wird die radiale Druckkraft des Schraubenkopfs einer im Schraubenschacht eingebrachten Schraube im Übergangsbereich deutlich reduziert. Das ist insbesondere bei mehreren, nebeneinander liegenden Schraubenschächten beziehungsweise Gehäusen von Vorteil, da sich deutlich weniger Druckkräfte in Anreihrichtung aufsummieren. Letztlich werden die radialen Druckkräfte je nach Art des Gehäusematerials eine mehr oder weniger starke Deformation des Gehäuses bewirken. Maßgeblich ist in diesem Zusammenhang, dass es nur eine minimale Deformation der Gehäuse in Anreihrichtung gibt. Denn insbesondere zwischen direkt benachbarten Gehäusen können aus nachteilig größeren Deformationen sogar Spalte entstehen. Dadurch würde die gesamte Anordnung der aneinander gereihten Gehäuse sich in sich verdrehen und/oder verbiegen. Dadurch aber, dass nur wenig Druckkräfte in Anreihrichtung wirken und dadurch die Gehäuse in Anreihrichtung weitgehend formstabil bleiben, bleibt beispielsweise die Kontaktüberdeckung der Schraubklemme zur Grundleiste sowie die Einlötbarkeit der Schraubklemme in eine Platine gewährleistet und somit die einwandfreie Funktion gegeben. Daher kann mit der vorliegenden Erfindung erreicht werden, dass sich mehrere Schraubenschächte beziehungsweise Gehäuse aneinander reihen lassen.Because there are no elevations in the screw shaft in the transition area or if, then with a smaller radial extent than other elevations outside the transition area, the radial compressive force of the screw head of a screw inserted in the screw shaft in the transition region is significantly reduced. This is particularly advantageous in the case of several screw shafts or housings lying next to one another, since significantly less pressure forces accumulate in the direction of arrangement. Ultimately, the radial compressive forces will cause a more or less severe deformation of the housing depending on the nature of the housing material. Decisive in this context is that there is only a minimal deformation of the housing in the direction of arrangement. Because especially between directly adjacent housings may even disadvantageously larger deformations arise gaps. As a result, the entire arrangement of the juxtaposed housing would be in itself twist and / or bend. As a result, however, that only little compressive forces acting in the direction of arrangement and thus the housing largely remain dimensionally stable in the direction of arrangement, for example, the contact overlap of the screw to the base bar and the solderability of the screw ensures a circuit board and thus given the perfect function. Therefore, it can be achieved with the present invention that several screw shafts or housings can be lined up.

Weiterhin sind Gehäusefreiräume vorgesehen, die zumindest teilweise die Schraubenschächte umgeben. In den Bereichen, in denen der Gehäusefreiraum den Schraubenschacht umgibt, wirken die radialen Druckkräfte des Schraubenkopfs einer im Schraubenschacht eingebrachten Schraube federnd auf die Schraubenschachtwände. Da die Schraubenschachtwände federnd in den Gehäusefreiraum hinein ausgelenkt werden, ist eine Deformation des Gehäuses jenseits der Gehäusefreiräume somit aus ausgeschlossen. Dadurch wird vorteilhaft erreicht, dass die Gehäusefreiräume die Wirkung der radialen Druckkräfte teilweise auffangen und sich das Gehäuse weniger verformt.
Wenn die Gehäusefreiräume außerhalb des Übergangsbereichs angeordnet sind, wird erreicht, dass sehr geringe Abstände zwischen den Schraubenschächten und damit sehr kleine Teilungen der Schraubklemme realisiert werden können.Furthermore, housing clearances are provided which at least partially surround the screw shafts. In the areas in which the housing free space surrounds the screw shaft, the radial pressure forces of the screw head of a screw inserted in the screw shaft act resiliently on the screw shaft walls. Since the screw shaft walls are resiliently deflected into the housing clearance, a deformation of the housing beyond the housing clearances is thus excluded. This advantageously ensures that the housing clearances partially absorb the effect of the radial compressive forces and the housing deforms less.
If the housing clearances are arranged outside the transition region, it is achieved that very small distances between the screw shafts and thus very small pitches of the screw can be realized.

Eine weitere Reduzierung der Gehäusedeformation lässt sich dadurch erreichen, dass die Erhebungen im Schraubenschacht ausschließlich im Bereich der Gehäusefreiräume angeordnet sind. Diese besonders bevorzugte Weiterbildung der Erfindung erreicht, dass die radialen Druckkräfte des Schraubenkopfs einer im Schraubenschacht eingebrachten Schraube ausschließlich federnd auf die Schraubenschachtwände wirken.A further reduction of the housing deformation can be achieved in that the elevations in the screw shaft are arranged exclusively in the area of the housing clearances. This particularly preferred development of the invention achieves that the radial compressive forces of the screw head of a screw inserted in the screw shaft act exclusively resiliently on the screw shaft walls.

Das bedeutet, die radialen Druckkräfte bewirken allein eine Auslenkung der Schraubenschachtwände in die Gehäusefreiräume hinein. Eine Deformation des Gehäuses erfolgt nicht, so dass die äußeren Abmaße des Gehäuses vollständig erhalten bleiben. Das hat den zusätzlichen Vorteil, dass sich die Schraubklemme passgenau in eine andere Anordnung einbauen lässt.
Ein weiterer Vorteil dieser Weiterbildung ergibt sich für die Materialauswahl des Gehäuses der Schraubklemme. Die federnde Wirkung der Schraubenschachtwand basiert wesentlich auf ihrer geringen Wandstärke, die durch den umgebenden Gehäusefreiraum ausgebildet wird. Daher werden radiale Druckkräfte auch dann noch federnd aufgefangen, wenn es sich um weniger elastisches Material, wie beispielsweise Duroplaste handelt. Damit stehen für die Auswahl des Gehäusematerials mehr Materialsorten zur Verfügung.
Die Stärke der radialen Druckkraft ist letztlich der Differenz aus dem Schraubenkopfdurchmesser und dem, durch die Erhebungen im Schraubenschacht, reduzierten Innendurchmesser des Schraubenschachts proportional. Da bei dieser Ausführung die Wirkung der radialen Druckkräfte ausschließlich federnd von den Schraubenschachtwänden aufgefangen wird, sind größere Schraubenkopfdurchmesser tolerierbar, als wenn die Druckkräfte auf ein massives Gehäuse wirken und dieses in Gänze verformen. Daher können bei dieser Weiterbildung der Erfindung größere Toleranzen der Schraubenkopfdurchmesser akzeptiert werden. Das vereinfacht die Herstellung der Schrauben, insbesondere bei sehr kleinen Schrauben, und reduziert die Herstellkosten.This means that the radial compressive forces alone cause a deflection of the screw shaft walls into the housing clearances. A deformation of the housing does not occur, so that the outer dimensions of the housing are completely retained. This has the additional advantage that the Screw terminal can be installed accurately in another arrangement.
Another advantage of this development results for the choice of material of the housing of the screw. The resilient action of the screw shaft wall is based essentially on its small wall thickness, which is formed by the surrounding housing clearance. Therefore, radial compressive forces are still resiliently collected even if it is less elastic material, such as thermosets. Thus, more material types are available for the selection of the housing material.
The strength of the radial compressive force is ultimately proportional to the difference between the screw head diameter and the reduced diameter of the screw shaft, due to the elevations in the screw shaft. Since in this embodiment, the effect of the radial compressive forces is absorbed only resiliently from the screw shaft walls, larger screw head diameter are tolerated, as if the pressure forces act on a solid housing and deform it in full. Therefore, larger tolerances of the screw head diameter can be accepted in this embodiment of the invention. This simplifies the manufacture of the screws, especially with very small screws, and reduces the manufacturing costs.

In einer Weiterbildung der Erfindung ist vorgesehen, dass sich die Erhebungen im Schraubenschacht von der Schraubenzuführöffnung beginnend in Richtung der Unterseite nur über einen Teil des Schraubenschachts erstrecken. Das hat den Vorteil, dass der Schraubenkopf einer eingebrachten Schraube bereits im obersten Teil des Schraubenschachts kraftschlüssig gehalten wird. Damit ist die Schraube gegen unbeabsichtigtes Lösen aus dem Schraubenschacht gesichert, noch bevor die Schraube in die ersten Gewindegänge eingedreht sein muss.In a development of the invention, it is provided that the elevations in the screw shaft extend from the screw feed opening starting in the direction of the underside over only a part of the screw shaft. This has the advantage that the screw head of an inserted screw is already held positively in the uppermost part of the screw shaft. Thus, the screw is secured against unintentional release of the screw shaft, even before the screw must be screwed into the first threads.

Fertigungstechnisch ist es besonders einfach, wenn sich die Erhebungen von der Unterseite aus betrachtet in Richtung der Schraubenzuführöffnung nur über einen vordersten Teil des Schraubenschachts erstrecken. Diese Ausführungsform der Erfindung zeichnet sich dadurch aus, dass die Erhebungen im Schraubenschacht keinen Hintergriff haben. Dadurch wird eine besonders einfache und schonende Entformung erreicht. Das wirkt sich auch vorteilhaft auf die Auswahlmöglichkeiten des Gehäusematerials aus. Denn es können auch solche Materialien verwendet werden, die aufgrund fehlender Elastizität eine Entformung bei vorhandenem Hintergriff nicht unbeschadet zulassen.Manufacturing technology, it is particularly simple if the surveys viewed from the bottom in the direction of the screw feed opening only over a foremost part of the screw shaft. This embodiment of the invention is characterized in that the elevations in the screw shaft have no rear grip. As a result, a particularly simple and gentle demolding is achieved. This also has an advantageous effect on the choices of housing material. Because it can also be used such materials that do not allow undamaged due to lack of elasticity demolding with existing rear grip.

In einer besonders bevorzugten Ausführung erstrecken sich die Erhebungen durchgängig über die gesamte Länge des Schraubenschachts. Diese Weiterbildung hat den Vorteil, dass der Schraubenkopf einer im Schraubenschacht eingebrachten Schraube bereits im obersten Teil des Schraubenschachts kraftschlüssig gehalten wird. Damit ist die Schraube gegen unbeabsichtigtes Lösen aus dem Schraubenschacht gesichert, noch bevor die Schraube in die ersten Gewindegänge eingedreht sein muss.
Ferner ist diese Ausführungsform vorteilhaft, da die Erhebungen im Schraubenschacht keinen Hintergriff haben. Dadurch wird eine besonders einfache und schonende Entformung erreicht. Das wirkt sich auch vorteilhaft auf die Auswahlmöglichkeiten des Gehäusematerials aus. Denn es können auch solche Materialien verwendet werden, die aufgrund fehlender Elastizität eine Entformung bei vorhandenem Hintergriff nicht unbeschadet zulassen.
Ein zusätzlicher Vorteil ergibt sich daraus, dass die Erhebungen den Innendurchmesser des Schraubenschachts über die gesamte Länge des Schraubenschachts gleichmäßig reduzieren. Dadurch übt der Schraubenkopf einer eingesetzten Schraube über die gesamte Länge des Schraubenschachts gesehen gleichermaßen radiale Druckkräfte auf die Erhebungen aus. Damit wird der Schraubenkopf über die gesamte Länge des Schraubenschachts gesehen gleichermaßen kraftschlüssig gehalten. Daher wird die Schraube über die gesamte Länge des Schraubenschachts gesehen gleichermaßen in Position gehalten, so dass daraus eine Führung für die Schraube erwirkt wird.In a particularly preferred embodiment, the elevations extend continuously over the entire length of the screw shaft. This development has the advantage that the screw head of a screw inserted in the screw shaft is already held positively in the uppermost part of the screw shaft. Thus, the screw is secured against unintentional release of the screw shaft, even before the screw must be screwed into the first threads.
Furthermore, this embodiment is advantageous because the elevations in the screw shaft have no rear grip. As a result, a particularly simple and gentle demolding is achieved. This also has an advantageous effect on the choices of housing material. Because it can also be used such materials that do not allow undamaged due to lack of elasticity demolding with existing rear grip.
An additional advantage results from the fact that the elevations evenly reduce the inner diameter of the screw shaft over the entire length of the screw shaft. As a result, the screw head of an inserted screw over the entire length of the screw shaft equally exerts radial compressive forces on the elevations. Thus, the screw head over the entire length of the screw shaft is viewed equally strong. Therefore, the screw is held equally in position over the entire length of the screw shaft, so that it is obtained from a guide for the screw.

Die erfindungsgemäße elektrische Vorrichtung sowie die Verwendung einer Schraube in der elektrischen Vorrichtung sind nachstehend in einem Ausführungsbeispiel beispielhaft beschrieben und zeichnerisch dargestellt.The electrical device according to the invention and the use of a screw in the electrical device are described below by way of example in one embodiment and shown in the drawing.

Die Figuren 1, 2 und 4 zeigen eine elektrische Vorrichtung 1. Sie umfasst ein Gehäuse 3 mit einer Oberseite 5 und einer Unterseite 7, die der Oberseite 5 gegenüber liegt. Ferner sind in dem Gehäuse 3 zwei Schraubenschächte 9 nebeneinander und zueinander parallel angeordnet. In dieser Ausführung befinden sich die Schraubenschächte 9 so nah beieinander, dass sie in einem Bereich nur durch eine gemeinsam genutzte Schraubenschachtwand 10 direkt miteinander verbunden sind (s. Fig. 1 und 2). In Figur 4 ist der Bereich, der die benachbarten Schraubenschächte 9 miteinander verbindet - in dieser Ausführung also die Schraubenschachtwand 10 - als Übergangsbereich 11 durch eine schwarz ausgefüllte Fläche gekennzeichnet. Auf der Oberseite 5 weisen die Schraubenschächte 9 jeweils eine Schraubenzuführöffnung 12 auf. In dieser Ausführung ist die Schraubenzuführöffnung 12 auf einem Niveau mit der übrigen Oberseite 5, das bedeutet, das Gehäuse 3 hat eine gesamt ebenmäßig plane Oberseite 5, wie insbesondere aus Fig. 3 hervorgeht. Das heißt, im Unterschied zum Stand der Technik ragen die Schraubenschächte 9 nicht über die Oberseite 5 des Übergangsbereichs 11 hinaus.The FIGS. 1 . 2 and 4 show an electrical device 1. It comprises a housing 3 with a top 5 and a bottom 7, which is the top 5 opposite. Further, in the housing 3, two screw shafts 9 are arranged side by side and parallel to each other. In this embodiment, the screw shafts 9 are so close to each other that they are directly connected to each other in an area only by a shared screw shaft wall 10 (s. Fig. 1 and 2 ). In FIG. 4 is the area that connects the adjacent screw shafts 9 together - in this embodiment, the screw shaft wall 10 - as a transition region 11 characterized by a black filled area. On the upper side 5, the screw shafts 9 each have a screw feed opening 12. In this embodiment, the screw feed opening 12 is at a level with the rest of the top 5, which means the housing 3 has an overall evenly flat top 5, as in particular Fig. 3 evident. That is, unlike the prior art, the screw shafts 9 do not project beyond the top 5 of the transition portion 11.

Über die Schraubenzuführöffnung 12 kann eine Schraube 13 mit Schraubenkopf 15 in den Schraubenschacht 9 eingebracht werden (s. Fig. 3). Dabei sind der Schraubenschacht 9 und der Schraubenkopf 15 derart aufeinander abgestimmt, dass der Innendurchmesser des Schraubenschachts 9 größer ist als der Durchmesser des Schraubenkopfs 15. Von ihrer Schraubenzuführöffnung 12 beginnend erstrecken sich die Schraubenschächte 9 in Richtung der Unterseite 7. Wie die Figuren 1 und 3 zeigen, befindet sich mit Blick von der Oberseite 5 in Richtung der Unterseite 7 unterhalb des Schraubenschachts 9 eine Klemmhülse 16 mit einem radialen Innengewinde einer an sich bekannten und deshalb nicht näher beschriebenen Schraubklemme. Der Schraubenschacht 9 und die Klemmhülse 16 sind derart aufeinander abgestimmt, dass das Gewinde der Schraube 13 in Funktionslage in das radiale Innengewinde der Klemmhülse 16 eingreift, so dass mit der Schraubklemme elektrische Leiter (nicht dargestellt) angeschlossen oder verbunden werden.About the screw feed opening 12, a screw 13 can be introduced with screw head 15 in the screw shaft 9 (s. Fig. 3 ). In this case, the screw shaft 9 and the screw head 15 are matched to one another such that the inner diameter of the screw shaft 9 is larger than the diameter of the screw head 15. Starting from its screw feed opening 12, the screw shafts 9 extend in the direction of the underside 7 FIGS. 1 and 3 show, looking from the top 5 in the direction of the bottom 7 below the screw shaft 9, a clamping sleeve 16 with a radial internal thread of a known and therefore not described in detail screw. The screw shaft 9 and the clamping sleeve 16 are matched to one another such that the thread of the screw 13 engages in functional position in the radial internal thread of the clamping sleeve 16, so that the screw terminal electrical conductors (not shown) are connected or connected.

An der Innenseite der Schraubenschächte 9 sind Erhebungen 17 angeordnet (s. Fig. 1, 3 und 4). In dieser Ausführung erstrecken sich die Erhebungen 17 von der Schraubenzuführöffnung 12 beginnend über die gesamte Länge des Schraubenschachts 9, wie insbesondere Figur 3 zeigt. Aufgrund der radialen Erstreckung der Erhebungen 17 wird der Innendurchmesser der Schraubenschächte 9 reduziert. Die radiale Erstreckung der Erhebungen 17 und der Schraubenkopf 15 sind derart aufeinander abgestimmt, dass der reduzierte Innendurchmesser des Schraubenschachts 9 kleiner ist als der Durchmesser des Schraubenkopfs 15 (s. Fig. 3 und 4). Daher übt der Schraubenkopf 15 auf die Erhebungen 17 eine radiale Druckkraft aus, derart dass der Schraubenkopf 15 kraftschlüssig gehalten wird.On the inside of the screw shafts 9 elevations 17 are arranged (s. Fig. 1 . 3 and 4 ). In this embodiment, the elevations 17 extend from the screw feed opening 12 beginning over the entire length of the screw shaft 9, in particular FIG. 3 shows. Due to the radial extent of the elevations 17, the inner diameter of the screw shafts 9 is reduced. The radial extent of the elevations 17 and the screw head 15 are matched to one another such that the reduced inner diameter of the screw shaft 9 is smaller than the diameter of the screw head 15 (s. Fig. 3 and 4 ). Therefore, the screw head 15 exerts on the elevations 17, a radial compressive force, so that the screw head 15 is held frictionally.

In dieser Ausführung befinden sich in dem Gehäuse 3 Gehäusefreiräume 19, die die Schraubenschächte 9 teilweise umgeben. Die Gehäusefreiräume 19 können direkt zwischen den benachbarten Schraubenschächten 9 angeordnet sein. In der hier vorliegenden Ausführung befinden sich die Gehäusefreiräume 19 außerhalb des zwischen den Schraubenschächten 9 angeordneten Übergangsbereichs 11. Wie die Figuren 1 und 4 zeigen, sind in dieser Ausführung die Erhebungen 17 ausschließlich im Bereich der Gehäusefreiräume 19 angeordnet. Daher besteht die Wirkung der radialen Druckkräfte des Schraubenkopfs 15 auf die Erhebungen 17 ausschließlich in einer federnden Auslenkung der Schraubenschachtwände in die Gehäusefreiräume 19 hinein.In this embodiment, 3 housing free spaces 19 in the housing, which surround the screw shafts 9 partially. The housing clearances 19 can be arranged directly between the adjacent screw shafts 9. In the present embodiment, the housing clearances 19 are located outside of the arranged between the screw shafts 9 transition region 11. Like the FIGS. 1 and 4 show, the elevations 17 are arranged exclusively in the area of the housing clearances 19 in this embodiment. Therefore, the effect of the radial compressive forces of the screw head 15 on the elevations 17 only in a resilient deflection of the screw shaft walls into the housing clearances 19 into it.
