Abstract

Prior art terminals with operating buttons and a contact member movable against the force of a spring are relatively bulky and complex. It is proposed to provide a part of a curved leaf spring as the contact member having at least one aperture (16) fitted in such a way above the conductor guide (8) that an edge (16a) of the aperture acts as the contact member. This design also permits the contacting of thin conductors.

Description

Anschlußklemme für elektrische Installationen Terminal block for electrical installations
Die Erfindung betrifft eine Anschlußklemme für elektrische Installationen, insbesondere für die Informationstechnik, mit einer in einem Gehäuse bewegbaren Kontaktstück, das unter der Kraft einer Feder gegen eine Führung für einen Leiter drück¬ bar ist, die zum Kontaktstück hin offen ist, wobei das Kon¬ taktstück Teil einer im Gehäuse gehaltenen Blattfeder ist, die mit einer Öffnung versehen ist, die so zur Führung für den Leiter angeordnet ist, daß ein Rand als Kontaktstück dient und am Leiter anlegbar ist.The invention relates to a connection terminal for electrical installations, in particular for information technology, with a contact piece which can be moved in a housing and which, under the force of a spring, can be pressed against a guide for a conductor which is open towards the contact piece, the contact Taktstück is part of a leaf spring held in the housing, which is provided with an opening which is arranged for guiding the conductor that an edge serves as a contact piece and can be applied to the conductor.
Anschlußklemmen mit Betätigungstasten sind bekannt. Diese be¬ stehen in der Regel aus einem U-förmigem Bauteil, das einen Führungskanal für den Leiter umgibt und mit dem von dem Tastteil abgewandten Schenkel das Kontaktstück bildet, das unter der Kraft einer Feder in den Führungskanal für den Lei¬ ter zur Kontaktierung desselben hereingedrückt wird.Terminals with actuation buttons are known. These generally consist of a U-shaped component which surrounds a guide channel for the conductor and forms the contact piece with the leg facing away from the feeler part, which under the force of a spring enters the guide channel for the conductor to make contact with the latter is pushed in.
Solche Bauarten sind verhältnismäßig aufwendig in der Her¬ stellung. Sie lassen vor allen Dingen dann keine sichere Kon¬ taktierung mehr zu, wenn die Durchmesser der Leiter sehr dünn werden, wie das insbesondere in der Informations- und Kommu¬ nikationstechnik der Fall ist. Auch der Raumbedarf der be¬ kannten Bauart ist verhältnismäßig hoch. Wird daher eine Vielzahl von Anschlüssen erforderlich, wie das in der Kommu¬ nikationstechnik der Fall ist, dann ergibt sich ein erhebli¬ cher Platzbedarf für solche Anschlußklemmen.Such types are relatively expensive to manufacture. Above all, they no longer permit reliable contacting if the diameters of the conductors become very thin, as is the case in particular in information and communication technology. The space requirement of the known type is also relatively high. Therefore becomes a If a large number of connections are required, as is the case in communication technology, then there is a considerable space requirement for such connection terminals.
Bekannt ist auch eine Anschlußklemme der eingangs erwähnten Art (US-A-50 69 638) . Dort ist eine einseitig in einer Gehäu- seδffnung eingespannte Blattfeder vorgesehen, die eine Öff¬ nung (oder eine Ausnehmung) aufweist, deren obereKante als Kontaktstück klemmend an dem Leiter anliegt, der auf der an¬ deren Seite an der Wand einer Führung in dem Gehäuse gehalten ist. Da bei dieser Bauart nur eine Öffnung zum Durchführen des Leiters vorgesehen ist, wird es notwendig, das nicht mit der Öffnung versehene Ende der Blattfeder fest im Gehäuse einzuspannen.Also known is a connecting terminal of the type mentioned at the beginning (US-A-50 69 638). There is a leaf spring clamped on one side in a housing opening, which has an opening (or a recess), the upper edge of which, as a contact piece, is in clamping contact with the conductor, which is on the other side against the wall of a guide in the housing is held. Since only one opening is provided for passing the conductor through with this type of construction, it becomes necessary to clamp the end of the leaf spring not provided with the opening firmly in the housing.
Der Erfindung liegt die Aufgabe zugrunde, eine Anschlußklemme der eingangs genannten Art so auszubilden, daß sie bei mög¬ lichst geringem Raumbedarf auch zur sicheren Kontaktierung dünner Leiter einsetzbar ist.The invention has for its object to provide a terminal of the type mentioned in such a way that it can also be used for reliable contacting of thin conductors with as little space as possible.
Zur Lösung dieser Aufgabe wird bei einer Anschlußklemme der eingangs genannten Art vorgesehen, daß die Blattfeder recht¬ eckige, fluchtend untereinander angeordnete Fenster aufweist, und mit diesen in gebogener Form so auf die Führung für die Leiter aufgesetzt ist, daß eines der Fenster als Klemmglied zur Befestigung an der Führung für den Leiter dient und das andere mit seinem Rand das Kontaktstück bildet, und daß die gebogene Blattfeder zwischen dem Boden eines Schachtes im Ge¬ häuse und eine Betätigungstaste eingesetzt ist. Diese Ausge¬ staltung ist äußerst einfach. Sie erlaubt aber die Verwirkli¬ chung relativ hoher Kontaktdrücke, weil wegen der Verwendung einer Blattfeder hohe elastische Kräfte zur Verfügung stehen und das Kontaktstück nur eine geringe Berührungsfläche auf¬ weist. Diese Ausgestaltung ist daher insbesondere zur Kontak¬ tierung auch dünner Leiter vorteilhaft, die in erfindungsge¬ mäßen Anschlußklemmen auch sicher gehalten sind. Diese Ausführung ist besonders vorteilhaft, wenn in Weiter¬ bildung der Erfindung die Leiterführung jeweils aus zwei pa¬ rallelen mit einem etwa V-förmigen Querschnitt versehenen Streifenprofilen besteht, die mit einem Anschlußkontakt ver¬ bunden sind. An diesen Streifenprofilen läßt sich die Blatt¬ feder mit ihrem Fenster in einfacher Weise verklemmen. Mit dem das Kontaktstück bildenden Rand des zweiten Fensters kann ein in der Leiterführung eingelegter Leiter zum einen ein¬ wandfrei kontaktiert, zum anderen aber auch fest in die V- förmige Vertiefung des Streifenprofiles gedrückt und dort ge¬ halten werden.To solve this problem it is provided in a connection terminal of the type mentioned that the leaf spring has rectangular, aligned windows aligned with one another, and is placed with them in a curved shape on the guide for the conductors so that one of the windows as a clamping member for Attachment to the guide for the conductor and the other forms the contact piece with its edge, and that the curved leaf spring is inserted between the bottom of a shaft in the housing and an actuating button. This configuration is extremely simple. However, it allows the realization of relatively high contact pressures because high elastic forces are available due to the use of a leaf spring and the contact piece has only a small contact area. This configuration is therefore particularly advantageous for contacting even thin conductors, which are also securely held in connection terminals according to the invention. This embodiment is particularly advantageous if, in a further development of the invention, the conductor guide in each case consists of two parallel strip profiles provided with an approximately V-shaped cross section, which are connected to a connection contact. The leaf spring with its window can be clamped to these strip profiles in a simple manner. With the edge of the second window forming the contact piece, a conductor inserted in the conductor guide can be contacted without problems on the one hand, but on the other hand also firmly pressed into the V-shaped recess of the strip profile and held there.
Bei dieser Ausführungsform ist es in Weiterbildung der Erfin¬ dung vorteilhaft, die Betätigungstaste mit Einstecköffnungen für die anzuschließenden Leiter zu versehen, die zu der Längsrichtung der Streifenprofile fluchten. Ein zusätzlicher Raumbedarf quer zur Betätigungsrichtung der Betätigungstaste ist daher nicht erforderlich.In this embodiment, in a further development of the invention, it is advantageous to provide the actuation button with insertion openings for the conductors to be connected, which are aligned with the longitudinal direction of the strip profiles. An additional space requirement transverse to the direction of actuation of the actuation key is therefore not necessary.
In Weiterbildung der Erfindung kann die Blattfeder einteilig mit einer zweiten Blattfeder ausgebildet und mit einem zwi¬ schen den Streifenprofilen verlaufenden Trennschnitt versehen sein. Diese Ausführung erlaubt trotz der Anordnung nur eines Blattfederteiles auch die Kontaktierung von Leitern mit ver¬ schiedenen Durchmessern, was natürlich auch bei Verwendung von zwei Blattfedern für die beiden die Leiterführung bilden¬ den Streifenprofile möglich wäre. Diese letztere Ausführung allerdings wäre sowohl in der Herstellung als auch bei der Montage aufwendiger.In a further development of the invention, the leaf spring can be formed in one piece with a second leaf spring and can be provided with a separating cut running between the strip profiles. Despite the arrangement of only one leaf spring part, this embodiment also allows the contacting of conductors with different diameters, which of course would also be possible if two leaf springs were used for the two strip profiles forming the conductor guide. However, this latter version would be more complex both in production and in assembly.
In Weiterbildung der Erfindung kann der Anschlußkontakt ein¬ teilig mit den Streifenprofilen ausgebildet und mit minde¬ stens einer Rastnase zur Verriegelung am Gehäuse versehen sein. Dies erlaubt eine verhältnismäßig einfache Herstellung.In a further development of the invention, the connection contact can be formed in one piece with the strip profiles and can be provided with at least one latching lug for locking on the housing. This allows a relatively simple manufacture.
Der Anschlußkontakt kann dabei als eine aus dem Gehäuse her¬ ausragenden Lδtfahne ausgebildet sein. Er kann aber auch mit zwei Kontaktzungen zur Direktsteckung von Leiterplatten ver¬ sehen sein, wobei diese Kontaktzungen auch um 90° oder um 180° zu der Längsrichtung der Leiterführungen, d.h. zu der Längsrichtung der Streifenprofile angeordnet sein können. Diese Maßnahme ermöglicht das Einstecken von Leiterplatten auch unter einem Winkel zu der Einsteckrichtung für die Lei¬ ter. Schließlich kann in Weiterbildung der Erfindung das Ge¬ häuse auf der der Betätigungstaste gegenüberliegenden Seite mit einer Stecköffnung zur Gegensteckung von Leitern versehen sein, die fluchtend zu den Leiterführungen liegen.The connection contact can be designed as a solder tab protruding from the housing. But he can also with Two contact tongues for direct plugging in of printed circuit boards can be seen, these contact tongues also being able to be arranged at 90 ° or 180 ° to the longitudinal direction of the conductor guides, ie to the longitudinal direction of the strip profiles. This measure enables the circuit boards to be inserted even at an angle to the direction of insertion for the conductors. Finally, in a further development of the invention, the housing on the side opposite the actuation button can be provided with a plug-in opening for mating conductors which are aligned with the conductor guides.

Fig. 14 schließlich eine weitere Variante einer erfindungs¬ gemäßen Anschlußklemme, bei der der Gegenkontakt nicht durch Lötfahnen oder Kontaktzungen, sondern durch direkte Gegensteckung weiterer Leiter er¬ folgt. In den Fig. 1 bis 8 ist eine Anschlußklemme (1) gezeigt, die Teil einer mit mehreren Anschlußklemmen versehenen Klemmlei¬ ste (2) ist, die alle parallel zueinander in der Klemmleiste (2) angeordnet sind. Im Ausführungsbeispiel ist nur die An¬ schlußklemme (1) und eine weitere Anschlußklemme (3) gezeigt. Da alle Anschlußklemmen identisch ausgebildet sind, be¬ schränkt sich die folgende Beschreibung nur auf die Anschlu߬ klemme (1) .14, finally, a further variant of a connecting terminal according to the invention, in which the mating contact is not made by soldering lugs or contact tongues, but by directly mating other conductors. 1 to 8 show a connection terminal (1) which is part of a terminal strip (2) provided with a plurality of connection terminals, all of which are arranged parallel to one another in the terminal strip (2). In the exemplary embodiment, only the connecting terminal (1) and a further connecting terminal (3) are shown. Since all connection terminals are of identical design, the following description is limited only to connection terminal (1).
Aus den Fig. 1 bis 5 wird deutlich, daß jede Anschlußklemme und auch die Anschlußklemme (1) in einem schachtartigen Hohl¬ raum (4) innerhalb des Gehäuses der Klemmleiste (2) angeord¬ net ist, und daß eine Betätigungstaste (5) in Richtung der Pfeile (6) verschiebbar in der Schachtführung (4) gehalten ist. Die Betätigungstaste (5) weist zwei Öffnungen (7) auf, die beim Ausführungsbeispiel kreisrund gestaltet sind und sich nach oben leicht konisch erweitern. Diese Öffnungen (7) fluchten zu zwei Streifenprofilen (8) aus einem leitfähigen Material, die beide (siehe auch Fig. 8) einstückig mit einem als Lötfahne ausgebildeten Anschlußkontakt (9) verbunden sind. Dieser Anschlußkontakt (9) weist im Bereich des Ver¬ bindungssteges (10) zu den beiden Streifenprofilen (8) eine Rastnase (11) auf, und kann mit dieser Rastnase beim Einstek¬ ken des in der Fig. 8 gezeigten Teiles im Sinn des PfeilesIt is clear from FIGS. 1 to 5 that each connection terminal and also the connection terminal (1) are arranged in a shaft-like cavity (4) within the housing of the terminal strip (2), and that an actuation button (5) is in Direction of the arrows (6) is slidably held in the shaft guide (4). The actuation button (5) has two openings (7), which are circular in the embodiment and widen slightly conically upwards. These openings (7) are aligned to form two strip profiles (8) made of a conductive material, both of which (see also FIG. 8) are connected in one piece to a connection contact (9) designed as a soldering lug. This connection contact (9) has a locking lug (11) in the area of the connecting web (10) to the two strip profiles (8) and can be used with this locking lug when inserting the part shown in FIG. 8 in the direction of the arrow
(12) in den Schacht (4) an einer nicht näher gezeigten Öff¬ nung des Schachtes (4) und des Gehäuses (2) verrasten. In gleicher Weise besitzt auch die Betätigungstaste (5) seitlich abragende Nasen (13) , die dazu dienen, die Betätigungstaste(12) snap into the shaft (4) at an opening (not shown in detail) of the shaft (4) and the housing (2). In the same way, the actuation button (5) also has protruding lugs (13) which serve to actuate the actuation button
(5) nach dem Einsetzen in den Schacht (4) an einem Herausfal¬ len nach oben zu hindern.(5) after insertion into the shaft (4) to prevent it from falling out upwards.
Zwischen der Betätigungstaste (5) und dem Boden (4a) des Schachtes (4) ist eine Blattfeder (14) (siehe Fig. 6 und 7) eingesetzt, die beim Einsetzen in den Schacht (4) unter Vor¬ spannung kommt und sich daher mit ihrem unteren Ende am Boden (4a) und mit ihrem oberen Ende an einem Vorsprung (30) der Betätigungstaste (5) abstützt. Die Blattfeder (14) besteht dabei aus zwei durch einen Trennschnitt (15) voneinander in ihrer Funktion getrennten Teilblattfedern (14a und 14b) , die jeweils mit zwei Fenstern (16 und 17) versehen sind und in ihrem unteren Bereich einteilig miteinander verbunden sind. Die Fenster (16 und 17) sind rechteckig ausgebildet. Die Fen¬ ster (16) sind wesentlich größer gestaltet als die Fenster (17) . Die Seitenkanten der Fenster (16 und 17) fluchten zu¬ einander, so daß die Fenster (16 und 17) jeweils auch fluch¬ tend untereinander liegen.A leaf spring (14) (see FIGS. 6 and 7) is inserted between the actuation button (5) and the bottom (4a) of the shaft (4), which comes under pretension when it is inserted into the shaft (4) and is therefore subject to tension with its lower end on the floor (4a) and with its upper end on a projection (30) of the actuating button (5). The leaf spring (14) is made in this case from two partial leaf springs (14a and 14b) separated from one another in their function by a separating cut (15), which are each provided with two windows (16 and 17) and are integrally connected to one another in their lower region. The windows (16 and 17) are rectangular. The windows (16) are significantly larger than the windows (17). The side edges of the windows (16 and 17) are flush with one another, so that the windows (16 and 17) are also flush with one another.
Die Abmessungen der Fenster (17) sind so gewählt, daß sich die Ober- und Unterkanten jeweils fest an den Streifenprofi¬ len (8) verkanten, wenn die Blattfeder (14) , wie aus den Fig. 2 und 4 ersichtlich ist, mit beiden Fenstern (16 und 17) auf die Streifenprofile (8) in gebogener Form so aufgesetzt wird, daß die obere Kante (16a) jedes der Fenster (16) und die bei¬ den parallel zu der Kante (16a) verlaufenden Kanten der Fen¬ ster (17) an den Streifenprofilen (8) anliegen.The dimensions of the windows (17) are selected so that the upper and lower edges each jam firmly on the strip profiles (8) when the leaf spring (14), as can be seen from FIGS. 2 and 4, with both Windows (16 and 17) are placed on the strip profiles (8) in a curved shape such that the upper edge (16a) of each of the windows (16) and the two edges of the windows running parallel to the edge (16a) (17) rest on the strip profiles (8).
Die Streifenprofile (8) sind als Leiterführungen ausgebildet und sind in etwa in der Form von Rinnen mit einem etwa V- förmigem Querschnitt ausgebildet, in dem die Enden von nicht gezeigten Leitern zum Zweck der Kontaktierung durch die Öff¬ nungen (7) der Betätigungstaste (5) hereingeführt werden kön¬ nen. Die Leiterenden liegen dann innerhalb der Rinnenführung der Streifenprofile (8) an und werden durch die Kante (16a) (siehe Fig. 5) fest und sicher gegen diese Streifenprofile (8) gedrückt, wenn die Kanten (16a) nicht so wie in Fig. 5 gezeigt, unmittelbar an den Streifenprofilen (8) , sondern an der Außenfläche von entsprechenden eingeschobenen Leitern an¬ liegen. Aus der Fig. 5 wird im übrigen auch klar, daß durch die Anordnung des Trennschnittes (15) durch die Öffnungen (7) auch Leiter verschiedener Durchmesser eingeführt werden kön¬ nen, die auch dann von der jeweiligen Kante (16a) der zuge¬ ordneten Blattfeder (14a oder 14b) kontaktiert werden können. Die Herstellung der Anschlußklemme nach der Erfindung erfolgt automatisch in einfacher Weise so, daß zunächst die Blattfe¬ dern in gebogenem Zustand auf die zugeordneten Streifenpro¬ file (8) aufgesetzt wird, daß dann die Streifenprofile mit der aufgesetzten Blattfeder mit ihrem Anschlußkontakt (9) durch die entsprechende Öffnung (17) (Fig. 4) des Schachtes (4) eingeschoben werden bis die Rastnase (11) einschnappt und daß dann die Betätigungstaste (5) aufgesetzt wird, die mit ihren Nasen (13) zur Lagesicherung ebenfalls hinter entspre¬ chende Vorsprünge des Schachtes (4) greift. In diesem Zustand liegt die Blattfeder unter Spannung im Schacht (4) . Bei Betä¬ tigung der Taste (5) wird die Blattfeder mit ihrem oberen Teil (der untere kann mit dem Fenster (17) fest an den Strei¬ fenprofilen (8) verklemmt sein) nach unten gebogen, so daß dadurch ihre Kante (16a) , die damit auch das Kontaktstück bildet, von den Streifenprofilen (8) entfernt wird und das Einführen eines Leiterendes erlaubt.The strip profiles (8) are designed as conductor guides and are approximately in the form of channels with an approximately V-shaped cross section, in which the ends of conductors, not shown, for the purpose of contacting through the openings (7) of the actuation button ( 5) can be introduced. The conductor ends then lie within the channel guide of the strip profiles (8) and are pressed firmly and securely against these strip profiles (8) by the edge (16a) (see FIG. 5) if the edges (16a) are not as shown in FIG. 5 shown, lie directly on the strip profiles (8), but on the outer surface of corresponding inserted conductors. 5 also makes it clear that the arrangement of the separating cut (15) through the openings (7) can also be used to insert conductors of different diameters, which then also correspond to the respective edge (16a) Leaf spring (14a or 14b) can be contacted. The connection clamp according to the invention is automatically produced in a simple manner so that first the leaf springs in the bent state are placed on the associated strip profiles (8), and then the strip profiles with the leaf spring attached with their connection contact (9) the corresponding opening (17) (Fig. 4) of the shaft (4) are pushed in until the locking lug (11) snaps in and that the actuating button (5) is then placed, which also lugs behind with its lugs (13) to secure the position Projections of the shaft (4) engages. In this state, the leaf spring is under tension in the shaft (4). When the button (5) is actuated, the leaf spring is bent downward with its upper part (the lower part can be firmly clamped to the strip profiles (8) with the window (17)), so that its edge (16a) , which thus also forms the contact piece, is removed from the strip profiles (8) and allows the insertion of a conductor end.
Die Fig. 9 zeigt eine Abwandlung der Anschlußklemme nach der Erfindung insofern, als hier keine Lötfahne (9) einstückig mit den beiden Streifenprofilen (8) verbunden sind, sondern zwei eine gabelförmige Steckeinrichtung bildende Kontaktzun¬ gen (18) , die als Anschlußkontakte dienen. Die Kontaktzungen (18) ragen bei dieser Variante aber nicht frei aus dem Gehäu¬ se der Anschlußklemmenleiste (2) heraus, sondern sind in ei¬ nem ansonsten ebenfalls für mehrere Anschlußklemmen ausgeleg¬ ten Gehäuse (2') einer Klemmenleiste gehalten, das auch noch die Enden der Kontaktzungen (18) umgibt, die in entsprechen¬ den Schlitzen (19) des Gehäuses (2') geführt sind. Das Gehäu¬ se (2') weist außerdem einen Einführschlitz (20) auf, so daß hier eine direkte Kontaktierung von eingeschobenen Leiter¬ platten durch die Kontaktzungen (18) erfolgen kann. Der übri¬ ge Aufbau der Betätigungstaste (5) und der in einem Schacht (4) angeordneten als Leiterführung dienenden Streifenprofile (8) ist gleich wie beim Ausführungsbeispiel der Fig. 1 bis 8. Die Fig. 11 bis 13 zeigen AusführungsVarianten eines An¬ schlußkontaktes ähnlich der Fig. 8 bzw. ähnlich der Fig. 10. Die Fig. 11 zeigt dabei die Möglichkeit, daß die Lδtfahne, die auch ein Steckpin sein kann, unmittelbar zwischen die beiden Streifenprofile (8) hereingesteckt und mit diesen ent¬ weder einteilig oder auch durch eine Schweißung verbunden ist. Der Steckpin (21) besitzt hier die Rastnase (11) zur Ge¬ häusebefestigung unmittelbar. Die Ausbildung des Schachtes muß entsprechend angepaßt werden.FIG. 9 shows a modification of the connecting terminal according to the invention in that no lugs (9) are integrally connected to the two strip profiles (8), but two contact tongues (18) forming a fork-shaped plug device, which serve as connecting contacts. In this variant, however, the contact tongues (18) do not protrude freely from the housing of the connecting terminal strip (2), but are held in a housing (2 ') of a terminal strip, which is also designed for a plurality of connecting terminals surrounds the ends of the contact tongues (18) which are guided in corresponding slots (19) in the housing (2 '). The housing (2 ') also has an insertion slot (20) so that here inserted printed circuit boards can be directly contacted by the contact tongues (18). The rest of the structure of the actuation button (5) and the strip profiles (8) arranged in a shaft (4) and serving as a conductor guide is the same as in the embodiment of FIGS. 1 to 8. 11 to 13 show design variants of a connection contact similar to FIG. 8 or similar to FIG. 10. FIG. 11 shows the possibility that the soldering lug, which can also be a plug pin, directly between the two strip profiles (8) inserted and connected to them either in one piece or by welding. The plug pin (21) here has the locking lug (11) for fastening the housing directly. The design of the shaft must be adapted accordingly.
Die Fig. 12 zeigt eine Variante der Kontaktzungen der Fig. 10 insofern, als hier die Steckzungen (22) unter 90° zu der Längsrichtung der Streifenprofile (8) abragen. Bei dieser Va¬ riante kann eine Direktkontaktierung von Leiterplatten durch Einführung der Leiterplatten senkrecht zu der Zuführrichtung der anzuschließenden Leiterenden erreicht werden.FIG. 12 shows a variant of the contact tongues of FIG. 10 insofar as the insertion tongues (22) project here at 90 ° to the longitudinal direction of the strip profiles (8). In this variant, direct contacting of printed circuit boards can be achieved by introducing the printed circuit boards perpendicular to the feed direction of the conductor ends to be connected.
Die Fig. 13 zeigt eine Variante insofern, als hier die Kon¬ taktzungen (23) um 180° gegenüber der Einsteckrichtung der Leiter versetzt, d.h. parallel zu den Streifenprofilen (8) angeordnet sind. Hier kann daher eine Direktkontaktierung durch Leiterplatten von der gleichen Seite her erfolgen, von der auch der Anschluß der Leiter erfolgt. Natürlich ist die Gehäuseform den Kontaktzungen der Fig. 12 und 13 entsprechend anzupassen.FIG. 13 shows a variant in that the contact tongues (23) are offset by 180 ° with respect to the direction of insertion of the conductors, i.e. are arranged parallel to the strip profiles (8). Therefore, direct contact can be made by means of circuit boards from the same side from which the conductors are connected. Of course, the shape of the housing must be adapted accordingly to the contact tongues of FIGS. 12 and 13.
Die Fig. 14 schließlich zeigt auch die Möglichkeit, daß neben den beiden Leiter (24 und 25) , die unterschiedliche Durchmes¬ ser haben, und die in der vorher geschilderten Weise durch die Öffnungen (7) der Betätigungstaste (5) einführbar sind, auch von der anderen Seite her die Kontaktierung der als Lei¬ terführungen dienenden Streifenprofile (8) durch Leiter (26) erfolgen kann, wenn das Gehäuse (2) der Anschlußklemmleiste mit Öffnungen (27) am Boden des Schachtes (4) versehen ist, die wiederum fluchtend zu der Längsrichtung der Streifenpro¬ file (8) verlaufen. In diesem Fall muß die Lagesicherung der Streifenprofile (8) durch gesonderte Maßnahmen gelöst werden. Es wäre aber auch möglich, daß die Lagesicherung über die Blattfeder (14) bzw. deren Teile (14a, 14b) erfolgt, die mit den Fenstern (17) jeweils die Sicherung der Lage der Strei¬ fenprofile (8) übernehmen kann.Finally, FIG. 14 also shows the possibility that, in addition to the two conductors (24 and 25), which have different diameters, and which can be inserted through the openings (7) of the actuation button (5) in the manner described above from the other side, the strip profiles (8) serving as conductor guides can be contacted by conductors (26) if the housing (2) of the connecting terminal strip is provided with openings (27) on the bottom of the shaft (4), which in turn run in alignment with the longitudinal direction of the strip profile (8). In this case, the position securing of the strip profiles (8) must be solved by separate measures. However, it would also be possible for the position to be secured via the leaf spring (14) or its parts (14a, 14b), which can take over the securing of the position of the strip profiles (8) with the windows (17).
Bei der in der Fig. 14 gezeigten Ausführungsform dient auch eine Kante des Fensters (17) zur Kontaktierung des Leiters. Es ist zu erkennen, daß das Ende des Leiters (26) zwischen der Unterkante des Fensters (17) und dem Streifenprofil (8) gehalten ist. Es wird bei dieser Variante zweckmäßig sein, die zunächst fest anliegenden Kanten des Fensters (17) mit einem geeigneten Werkzeug (28) wegzudrücken, ehe der Leiter (26) eingeführt wird. Diese Ausführungform empfiehlt sich insbesondere dann, wenn beispielsweise empfindliche und auf¬ wendige Datenverarbeitungsgeräte in Bereichen installiert werden sollen, zu denen vor der eigentlichen Endmontage noch freier Zutritt besteht. In diesem Fall können die Datenverar¬ beitungsgeräte mit entsprechenden Anschlußleitern (z.B. 26) an die erfindungsgemäße Anschlußklemme gelegt werden, so daß zum Zeitpunkt der Endmontage nur noch die ortsfest liegenden Leiter (z.B. 24, 25) in einfacher Weise und ohne Werkzeuge an die Anschlußklemmen gelegt werden können. In the embodiment shown in FIG. 14, an edge of the window (17) also serves to contact the conductor. It can be seen that the end of the conductor (26) is held between the lower edge of the window (17) and the strip profile (8). With this variant, it will be expedient to press away the edges of the window (17) which are initially firmly in contact with a suitable tool (28) before the conductor (26) is inserted. This embodiment is particularly recommended if, for example, sensitive and complex data processing devices are to be installed in areas to which there is still free access before the actual final assembly. In this case, the data processing devices with appropriate connecting conductors (for example 26) can be placed on the connecting terminal according to the invention, so that at the time of final assembly only the fixed conductors (for example 24, 25) are connected to the connecting terminals in a simple manner and without tools can be.
