- the ES 2 159 247 A1 shows an electrical terminal with a housing for a pluggable electrical conductor with a spring terminal.
- a lever-like pusher is integrally formed on the upper side thereof.
- a pin is provided, which engages in a recess of the housing and in a recess of a contact insert and acts upon actuation of the pusher on the clamping spring to release the clamping contact.
- the pusher is overall very large and elaborately designed.
- a comparable embodiment is in the EP 1 182 750 A2 disclosed.
- DE 37 43 409 A1 shows a screwless connection terminal with an insulating housing and with a substantially Z-shaped contact insert and with a release lever which is integrally formed on a Z-like elastic web of a cover.
- DE 33 46 027 C2 discloses an electrical terminal having a spring force clamping member formed around more than one wrap of an annularly wound leaf spring with overlapping legs.
- a rocker switch is formed on the terminal housing and provided with a predetermined bending point.
- On the terminal housing a limit stop for the rocker switch is provided.
- EP 0 212 330 A2 discloses a terminal with a two-part insulating body, which has a base body and ice plug-lockable second component.
- a pushbutton is connected to the rear side of the rigid second component and extends over a cover wall covering the contact part.
- the object of the invention is to provide an improved electrical terminal for the connection of an electrical conductor, which ensures a secure clamping of the electrical conductor and at the same time has a simple, compact construction and can be safely operated.
- the angular design of the pusher allows a relatively long effective pusher with a correspondingly long lever arm, which is particularly in confined space conditions or very small electrical terminals with small Isolierstoffgeophusen advantage.
- the inventive design of the pusher makes it possible to provide an effective pusher for actuating a contact frame.
- the pusher arm is preferably formed from a first, the course of a rear housing adapted Pückerarmteil and a second, the course of a housing surface adapted Prankerarmteil. Furthermore, the pusher arm is thus arranged in a recess of the insulating material.
- the pusher arm on an actuating surface with a trough-shaped recess, so that in a simple way a piecemeal option for an operating tool is created so that the pusher can be operated safely.
- the pusher arm is designed elastically deformable, so that a simple movement or deflection of the pusher with minimal design effort can be guaranteed.
- the spring element is designed as at least one leaf spring or a spring leg, so that in the preferred embodiment of the contact frame in the manner of a channel and the contact frame to form a PorterklemmanBankes on each side wall in each case a leaf spring in the manner of a punched out of a flat metal part tongue has, which is bent out of the plane of the flat metal part, such that the free end of the leaf spring forms a directed against the electrical conductor clamping edge.
- the electrical terminal is formed of only two components, the insulating housing with integrated pusher and a one-piece contact frame, so that a simple structure and easy installation can be ensured at low cost.
- the pusher can be easily pressed between the leaf springs to open the terminal connection of the electrical conductor by pushing apart of the leaf springs.
- the pusher on a corresponding wedge-shaped pusher surface, which is formed at the end connected to the insulating housing end of the handle arm.
- the pusher arm In the assembled state of the electrical terminal, in which the contact frame is inserted in the insulating housing, the pusher arm is under a bias, so that the pusher arm over the surface of the housing top protrudes.
- the trigger arm Characterized in that the trigger arm is subjected in the unactuated state of a bias voltage, the voltage with which the trigger arm is acted upon, be kept small.
- the value of the bias voltage is relatively small, since the deflection of the trigger arm in the unactuated state is also relatively small.
- the deflection of the pusher arm in the actuated position in the insulating material inside is also not much much larger than in the unactuated state, so that the voltages, which is subjected to the pusher, can be kept small overall.
- the low voltage levels within the pusher or pusher arm help to keep the pusher and thus the insulating material housing small.
- an overload protection is provided for this purpose.
- the deflection of the spring element designed as a leaf spring spring can be limited by side walls and / or intermediate walls of the insulating material housing. Further advantageous is the limitation of the deflection of the pusher arm of the pusher by a contact of the pusher arm on at least one spring element formed as a leaf spring.
- the FIG. 1 shows an inventive electrical terminal 1 with an insulating 2, in which a metallic contact frame 4 was added is.
- the insulating housing 2 has at one end face 19 at least one conductor insertion opening 3 for the insertion of an electrical conductor 5 (FIG. FIG. 4 ).
- the terminal 1 is bipolar, each with a conductor insertion opening 3 and a contact frame 4 per pole executed.
- the terminal can also have any other number of poles.
- connection regions 16 of the contact frame 4 which contact corresponding contact sections 28, eg printed conductors, of a printed circuit board 7 ( FIG. 2 ).
- the connection regions 16 are connected to the contact sections 28 in particular via a solder connection (SMD solder connection), but a plug connection is also conceivable.
- SMD solder connection solder connection
- a plug connection is also conceivable.
- the insulating material has been omitted, so that the connection of the electrical conductor 5 to the contact frame 4 can be seen.
- the electrical conductor 5 is inserted through an annularly curved, at least almost closed running channel input 8 of the Kunststoffhornes 4, wherein the stripped end 6 of the electrical conductor 5 between the leaf springs 9 formed as side walls of the channel-shaped contact frame 4, is added.
- the leaf springs 9 are bent out of a flat metal part and their free ends form a clamping edge 10, so that the two opposite clamping edges 10 of the leaf springs 9 form a terminal point for the electrical conductor 5.
- the area from the channel entrance 8 of the contact frame 4 adjoining the conductor insertion opening 3 up to the nip formed by the clamping edges 10 defines a conductor insertion area 30.
- the structure of the contact frame 4 is in the FIG. 3 clearly visible, it can be seen that the formation of the clamping edge 10 at the free end of the leaf spring 9 an additional, directed against the electrical conductor 5 exhibition 12 is embossed or molded to improve the clamping action. Furthermore, the contact frame 4 has a contact bottom 11, which in such a way from the Surface of a flat metal part is exposed or bent out, that this is carried by the channel entrance 8 in the direction of the clamping point, ie substantially in the conductor insertion region 30, rising in the direction of an inserted conductor 5 inclined. At the contact bottom 11, one end at the channel entrance 8 is followed by a first contact region 16 and at the other end a second contact region 16. In addition, in FIG.
- the leaf spring 9 respectively on its side remote from the contact bottom 10 a starting slope 12, which is directed in each case to the outside of the terminal 1.
- the chamfers 12 of a contact frame 4 thus together form an upward, facing away from the contact bottom 10 funnel-shaped receptacle.
- FIGS. 4 5a and 5b each show a sectional view of the invention composed of a contact frame 4 and an insulating material 2 electrical terminal 1, wherein in the FIG. 4 in addition, a connected electrical conductor 5 is shown.
- the housing inner wall 31 has an oblique region, within which the housing inner wall 31 is designed to be inclined with respect to an inserted conductor 5. This inclined region lies within the above-defined conductor insertion region 30 or may also extend over the entire conductor insertion region 30.
- the conductor insertion region 30 due to the design of the contact frame 4 with its leaf springs 9 and its contact base 10 and the housing inner wall 31 of the insulating housing 2 has an at least partially funnel-shaped design, it being clear that the funnel-shaped conductor insertion region 30 is composed of the contact frame 4 and the insulating 2.
- the funnel-shaped conductor insertion region 30 is peripherally closed at least almost completely. Only between the leaf springs 9 and the contact bottom 10 on the one hand and the leaf springs 9 and the Gescouseinnenwandung 31 on the other hand, narrow gaps are present.
- the cross section of the conductor insertion region 30 is executed in the embodiment substantially rectangular or square, but may also have any other shape, in particular round or at least partially round or arcuate.
- the funnel-shaped conductor insertion region 30 forms a guide for a plug-in electrical conductor 5, in particular for its stripped end 6, so that the stripped end can be purposefully fed to the clamping point.
- the electrical connection terminal 1 can also be used for multi-wire electrical conductors 5, in particular when the clamping point formed by the clamping edges 10 is opened by an actuating element which is designed as a pusher 21 prior to the insertion of the electrical conductor 5.
- the individual wires of the stranded conductor 5 can not escape due to the circumferentially nearly closed conductor insertion region 30 and are securely held by the clamping edge 10 by clamping.
- the end of the funnel-shaped section of the conductor introduction region 30 with the larger cross-section facing the conductor insertion opening 3 can also, if desired, serve as a stop for the insulated section of the electrical conductor 5.
- the funnel-shaped conductor insertion region 30 is composed of the insulating housing 2 and the contact frame 4 and of formed these two Baueilen, a simple and effective conductor guidance is achieved, in particular, the contact frame 4 can be very simple, compact and material-saving.
- a pusher 21 as an actuating element with a pusher arm 23 can be seen, which is designed in one piece with the insulating material 2.
- the pusher 21 acts on run-on slopes 12 and presses on actuation these chamfers 12 together with the leaf spring 9, ie, when pressed with a force F in the direction of the insulating 2, apart.
- the clamping edges 10 of the leaf spring 9 are pressed apart and opened the terminal point for removing an electrical conductor 5 or plugging an electrical conductor 5, in particular a stranded conductor 5.
- the trigger arm 23 is as shown in FIGS. 6a and 6b in one piece in the region of the housing rear side 20, preferably in its lower half facing away from the housing upper side 18, formed on the insulating housing 2.
- the pusher arm 23 follows the contour of the insulating material housing 2, so that a first pusher arm part 24 connected to the housing rear wall 20 extends approximately in the plane of the housing rear side 20 or approximately parallel thereto.
- the contour of the pusher arm 23 follows in the further course of the contour of the transition from the housing rear side 20 to the housing top side 18, so that a second pusher arm part 25 which is integrally connected to the first pusher arm part 24 approximately in the plane of the housing top 18 or approximately parallel thereto runs.
- the housing rear side 20 and the housing upper side 18 are arranged at an angle to each other, preferably, the housing rear side 20 and the housing top 18 are arranged at least approximately at right angles to each other.
- the pusher arm 23 is thus substantially formed as an angle.
- an actuating surface 27 is integrally formed on its end facing away from the first presser arm part, which in the present embodiment is trough-shaped, but alternatively also any other desired shape, for example slit or phillips shape, can accept. It can thus be seen that the pusher 21 is arranged in a housing recess 22, which extends over the housing rear side 20 and the housing upper side 18.
- the housing recess 22 is designed substantially as a breakthrough, so that the pusher 21 can act on the arranged in the interior of the insulating housing 2 contact frame 4.
- the pusher 21 as an actuating element is thus integrated with its angled embodiment in the wall or surface of the insulating housing 2 and constitutes a part of the insulating housing 2 itself.
- the pusher arm 23 and the outer surface is located substantially in the plane of the surface contour of the insulating housing 2, both in the area of the housing top 18 and in the region of the rear housing 20.
- the pusher 21 is at least slightly opposite the housing upper side 18, as shown in FIG. 5a is recognizable.
- the chamfers 12 of the contact frame 4 lie on the pusher 21 or more precisely on the pusher surface 26 (FIG. FIG. 7 ) and deflect the pusher 21 to the outside, so that the pusher arm 23 is under a resilient bias.
- the actuated state is shown, in which the pusher 21 is acted upon by an actuating force F in the region of the trough-like actuating surface 27. It can be seen that the pusher arm 23 deforms substantially uniformly elastically under the actuating force F, the region of the pusher 21 with the actuating surfaces 26 being inserted between the leaf springs 9.
- the pusher arm 23 has a substantially uniform thickness or thickness for uniform elastic deformation.
- the pusher 21 is displaced from the position projecting beyond the housing upper side 18 into a position in which the pusher arm 23, in particular the second pusher arm part 25, dips into the insulating material housing 2.
- the elastic bias of the pusher arm 23 is released and the pusher arm 23 subjected to a reverse tension, so that the pusher arm endeavors to move outward again in order to reach its starting position.
- the Figures 6a and 6b represent the insulating housing 2 as a single part, in particular, the described construction of the pusher 21 and the connection of the pusher 23 to the insulating material 2 are clearly visible again. Furthermore, it can be seen that the insulating housing 2 has recesses 32 on a housing underside, into which the contact areas 16 of the contact frame 4 engage, so that these contact areas 16 can protrude beyond the housing rear side 20 and the housing front side 19 with the conductor insertion openings 3 (see also FIG FIG. 1 ). At the same time it is achieved that the housing underside of the assembled electrical terminals forms a substantially flat surface without protruding components. The insulating material housing 2 can thus extend as far as the surface of the printed circuit board 7 in the state arranged on the printed circuit board 7 or rest on the printed circuit board 7.
- the pusher surface 26 of the pusher 21 is formed substantially wedge-shaped and acts on the corresponding inclined ramps 12 of the contact frame 4.
- the pusher 21 with a force F on the actuating surface 27 slides the wedge-shaped pusher surface 26 on the chamfers 12, dips between the leaf springs 9 and pushes them apart.
- the leaf springs 9 press the pusher 21 back into the starting position via the starting bevels 12 and the corresponding actuating surface 26 due to their restoring force.
- the illustrated angular design of the pusher 21 allows a relatively long effective pusher 23 with a correspondingly long lever arm, which is particularly in confined space conditions or very small electrical terminals with small Isolierstoffgeophusen advantage. This is especially the case with miniaturized terminals made possible by the inventive design of the pusher 21 in the first place to provide an effective pusher 21 for the operation of a contact frame 4.
- the voltage with which the pusher arm 23 is acted upon be kept small.
- the value of the bias voltage is relatively small, since the deflection of the pusher arm 23 in the unactuated state is also relatively small.
- the deflection of the pusher arm 23 in the actuated position in the insulating material 2 is also not much much larger than in the unactuated state, so that the voltages which the pusher arm 23 is subjected to can also be kept relatively small.
- the pusher 21 can be kept very small overall and thus is particularly suitable for very small-sized terminals.
- FIG. 7 It can be seen that the arranged on the leaf springs 9 chamfers 12 abut at a sufficient deflection of the leaf springs 9 on the side walls 33 of the insulating 2 and / or one or more arranged between the poles of the Anschluß1 intermediate walls 34 of the insulating housing 2.
- the side walls 33 and / or intermediate walls 34 thus limit a deflection of the leaf springs 9 and thus prevent them from being overloaded and thus from being able to plastically deform or break.
- Trigger arm can be realized. Due to the limited deflection of the leaf springs 9, only a limited intermediate space can arise between two mutually associated leaf springs. If the maximum width of the portion of the pusher arm 23, which dips between the leaf springs 9 is greater than the gap between the maximum deflected leaf springs 9, the pusher 23 can be deflected only limited, so that this can not be subjected to excessive stress and breaking the pusher arm 23 is effectively avoided.
- An overload protection for the pusher 21 or the pusher arm 23 can also be achieved by providing a stop on the section of the pusher arm 23 which dips between the leaf springs 9, which stops at a maximum deflection of the pusher arm or at a maximum insertion depth on the leaf springs 9 or rests on the run-on slopes 12, so that a further deflection of the pusher arm is prevented and damage to the pusher 21 is avoided.

Die Erfindung betrifft eine elektrishe Anschlussklemme mit einer Betätigungseinrichtung, wobei die elektrische Anschlussklemme einen in einem Isolierstoffgehäuse angeordneten Kontaktrahmen mit einem Leiterklemmanschluss für einen elektrischen Leiter umfasst und die Betätigungseinrichtung ein als Drücker ausgebildetes Betätigungselement umfasst, welches einstückig mit dem Isolierstoffgehäuse verbunden ist, und wobei der Leiterklemmanschluss am Kontaktrahmen durch mindestens ein Federelement gebildet wird, dessen freies Ende eine gegen den elektrischen Leiter gerichtete und mit einer Klemmkraft beaufschlagten Klemmkante bildet und der Leiterklemmanschluss durch ein Einwirken des Drückers auf das mindestens eine Federelement geöffnet werden kann, indem durch den Drücker eine Kraft entgegen der Klemmkraft auf das Federelement aufgebracht wird.The invention relates to an electrical connection terminal with an actuating device, wherein the electrical connection terminal comprises a arranged in an insulating housing contact frame with a Leitererklemmanschluss for an electrical conductor and the actuator comprises a handle formed as actuating element, which is integrally connected to the insulating housing, and wherein the conductor clamping connection is formed on the contact frame by at least one spring element whose free end forms a against the electrical conductor directed and acted upon by a clamping force clamping edge and the Leiterklemmanschluss can be opened by an action of the pusher on the at least one spring element by the pusher a force against the Clamping force is applied to the spring element.
Die
Aufgabe der Erfindung ist es, eine verbesserte elektrische Anschlussklemme für den Anschluss eines elektrischen Leiters bereitzustellen, welche eine sichere Klemmung des elektrischen Leiters gewährleistet und gleichzeitig einen einfachen, kompakten Aufbau aufweist und sicher betätigt werden kann.The object of the invention is to provide an improved electrical terminal for the connection of an electrical conductor, which ensures a secure clamping of the electrical conductor and at the same time has a simple, compact construction and can be safely operated.
Gelöst wird die Aufgabe durch die elektrische Anschlussklemme mit den Merkmalen des Anspruchs 1.The object is achieved by the electrical terminal with the features of claim 1.
Die winkelförmige Ausbildung des Drückers ermöglicht einen verhältnismäßig langen wirksamen Drückerarm mit einem dementsprechend langen Hebelarm, was insbesondere bei beengten Bauraumverhältnissen oder sehr kleinen elektrischen Anschlussklemmen mit kleinen Isolierstoffgehäusen von Vorteil ist. So wird es insbesondere bei miniaturisierten Anschlussklemmen durch die erfindungsgemäße Ausbildung des Drückers überhaupt erst ermöglicht, einen wirksamen Drücker für die Betätigung eines Kontaktrahmens vorzusehen.The angular design of the pusher allows a relatively long effective pusher with a correspondingly long lever arm, which is particularly in confined space conditions or very small electrical terminals with small Isolierstoffgehäusen advantage. Thus, it is in the case of miniaturized connection terminals that the inventive design of the pusher makes it possible to provide an effective pusher for actuating a contact frame.
Die beiden in einem Winkel zueinander angeordneten Oberflächen sind zumindest nahezu senkrecht zueinander angeordnet. Somit ist der Drückerarm bevorzugt aus einem ersten, dem Verlauf einer Gehäuserückseite angepassten Drückerarmteil und einem zweiten, den Verlauf einer Gehäuseoberfläche angepassten Drückerarmteil gebildet. Des Weiteren ist der Drückerarm damit in einer Ausnehmung des Isolierstoffgehäuses angeordnet.The two surfaces arranged at an angle to each other are arranged at least nearly perpendicular to each other. Thus, the pusher arm is preferably formed from a first, the course of a rear housing adapted Pückerarmteil and a second, the course of a housing surface adapted Prankerarmteil. Furthermore, the pusher arm is thus arranged in a recess of the insulating material.
In einer besonders vorteilhaften Ausführungsform weist der Drückerarm eine Betätigungsfläche mit einer muldenförmigen Ausnehmung auf, so dass auf einfache Weise eine Ansetzmöglichkeit für ein Betätigungswerkzeug geschaffen ist, so dass der Drücker sicher betätigt werden kann.In a particularly advantageous embodiment, the pusher arm on an actuating surface with a trough-shaped recess, so that in a simple way a piecemeal option for an operating tool is created so that the pusher can be operated safely.
Bevorzugt ist der Drückerarm elastisch verformbar gestaltet, so dass eine einfache Bewegung bzw. Auslenkung des Drückers bei minimalem konstruktivem Aufwand gewährleistet werden kann.Preferably, the pusher arm is designed elastically deformable, so that a simple movement or deflection of the pusher with minimal design effort can be guaranteed.
In einer bevorzugten Ausführungsform ist das Federelement als zumindest eine Blattfeder oder ein Federschenkel ausgebildet, so dass in der bevorzugten Ausbildung des Kontaktrahmens in Art eines Kanals und der Kontaktrahmen zur Bildung eines Leiterklemmanschlusses an jeder Seitenwand jeweils eine Blattfeder in Art einer aus einem flachen Metallteil ausgestanzten Zunge aufweist, welche aus der Ebene des flachen Metallteil herausgebogen ist, derart, dass das freie Ende der Blattfeder eine gegen den elektrischen Leiter gerichtete Klemmkante bildet. Somit wird die elektrische Anschlussklemme aus lediglich zwei Bauteilen, dem Isolierstoffgehäuse mit integriertem Drücker sowie einem einteiligen Kontaktrahmen gebildet, so dass ein einfacher Aufbau und eine einfache Montage mit niedrigen Kosten gewährleistet werden kann.In a preferred embodiment, the spring element is designed as at least one leaf spring or a spring leg, so that in the preferred embodiment of the contact frame in the manner of a channel and the contact frame to form a Leiterklemmanschlusses on each side wall in each case a leaf spring in the manner of a punched out of a flat metal part tongue has, which is bent out of the plane of the flat metal part, such that the free end of the leaf spring forms a directed against the electrical conductor clamping edge. Thus, the electrical terminal is formed of only two components, the insulating housing with integrated pusher and a one-piece contact frame, so that a simple structure and easy installation can be ensured at low cost.
An den Blattfedern ist jeweils eine zur Außenseite der elektrischen Anschlussklemme gerichtete Anlaufschräge angeformt, welche zueinander trichterförmig ausgestellt sind. Somit kann der Drücker auf einfache Weise zwischen die Blattfedern eingedrückt werden, um den Klemmanschluss des elektrischen Leiters durch Auseinanderdrücken der Blattfedern zu öffnen. Hierzu weist der Drücker eine korrespondierende keilförmige Drückerfläche auf, welche an dem am Isolierstoffgehäuse angebunden Ende abgewandte Ende des Drückerarms ausgebildet ist.On the leaf springs in each case a directed to the outside of the electrical terminal run-on slope is formed, which are issued to each other funnel-shaped. Thus, the pusher can be easily pressed between the leaf springs to open the terminal connection of the electrical conductor by pushing apart of the leaf springs. For this purpose, the pusher on a corresponding wedge-shaped pusher surface, which is formed at the end connected to the insulating housing end of the handle arm.
Im montierten Zustand der elektrischen Anschlussklemme, in dem der Kontaktrahmen in dem Isolierstoffgehäuse eingesetzt ist, steht der Drückerarm unter einer Vorspannung, so dass der Drückerarm über die Oberfläche der Gehäuseoberseite hervorsteht. Dadurch, dass der Drückerarm im unbetätigten Zustand einer Vorspannung unterworfen ist, kann die Spannung, mit welcher der Drückerarm beaufschlagt wird, klein gehalten werden. Der Wert der Vorspannung ist relativ klein, da die Auslenkung des Drückerarms im unbetätigten Zustand auch relativ klein ist. Die Auslenkung des Drückerarms in der betätigten Stellung in das Isolierstoffgehäuse hinein ist auch nicht Wesentlich viel größer als im unbetätigten Zustand, so dass die Spannungen, welcher der Drückerarm unterworfen wird, insgesamt klein gehalten werden können. Die niedrig gehaltenen Spannungswerte innerhalb des Drückers bzw. des Drückerarms tragen dazu bei, dass der Drücker und damit auch das Isolierstoffgehäuse klein gehalten werden kann.In the assembled state of the electrical terminal, in which the contact frame is inserted in the insulating housing, the pusher arm is under a bias, so that the pusher arm over the surface of the housing top protrudes. Characterized in that the trigger arm is subjected in the unactuated state of a bias voltage, the voltage with which the trigger arm is acted upon, be kept small. The value of the bias voltage is relatively small, since the deflection of the trigger arm in the unactuated state is also relatively small. The deflection of the pusher arm in the actuated position in the insulating material inside is also not much much larger than in the unactuated state, so that the voltages, which is subjected to the pusher, can be kept small overall. The low voltage levels within the pusher or pusher arm help to keep the pusher and thus the insulating material housing small.
Um eine Beschädigung, insbesondere ein Brechen, des zumindest einen Federelements und/oder des Drückers wirksam zu vermeiden ist in einer bevorzugten Ausführungsform ein Überlastschutz hierfür vorgesehen. Vorteilhafterweise ist dabei die Auslenkung des als Blattfederfeder ausgebildeten Federelements durch Seitenwände und/oder Zwischenwände des Isolierstoffgehäuses begrenzbar. Weiterhin vorteilhaft ist die Begrenzung der Auslenkung des Drückerarms des Drückers durch eine Anlage des Drückerarms an zumindest einem als Blattfeder ausgebildeten Federelement. Diese Ausbildungsformen ermöglichen einen Überlastschutz ohne wesentliche Anpassungen der elektrischen Anschlussklemme und sind daher kostengünstig.In order to effectively avoid damage, in particular breakage, of the at least one spring element and / or the pusher, in a preferred embodiment an overload protection is provided for this purpose. Advantageously, the deflection of the spring element designed as a leaf spring spring can be limited by side walls and / or intermediate walls of the insulating material housing. Further advantageous is the limitation of the deflection of the pusher arm of the pusher by a contact of the pusher arm on at least one spring element formed as a leaf spring. These forms of training allow overload protection without significant adjustments to the electrical terminal and are therefore inexpensive.

Im Bereich des freien Endes der Blattfedern 9, an welchem jeweils die Klemmkante 10 ausgebildet ist, weist die Blattfeder 9 jeweils an ihrer dem Kontaktboden 10 abgewandten Längsseite eine Anlaufschräge 12 auf, welche jeweils zur Außenseite der Anschlussklemme 1 gerichtet ist. Die Anlaufschrägen 12 eines Kontaktrahmens 4 bilden somit zusammen eine nach oben gerichtete, vom Kontaktboden 10 abgewandte trichterförmige Aufnahme.In the region of the free end of the

Es ist in diesen Darstellungen ferner erkennbar, dass der Leitereinführungsbereich 30 auf Grund der Gestaltung des Kontaktrahmens 4 mit seinen Blattfedern 9 und seinem Kontaktboden 10 sowie der Gehäuseinnenwandung 31 des Isolierstoffgehäuses 2 eine zumindest abschnittsweise trichterförmige Ausbildung aufweist, wobei deutlich wird, dass der trichterförmige Leitereinführungsbereich 30 aus dem Kontaktrahmen 4 und dem Isolierstoffgehäuse 2 zusammengesetzt ist. Der trichterförmige Leitereinführungsbereich 30 ist dabei umfangsseitig zumindest nahezu vollständig geschlossen. Lediglich zwischen den Blattfedern 9 und dem Kontaktboden 10 einerseits und den Blattfedern 9 und der Gehäuseinnenwandung 31 andererseits sind schmale Spalte vorhanden. Der Querschnitt des Leitereinführungsbereiches 30 ist im Ausführungsbeispiel im Wesentlichen rechteckig bzw. quadratisch ausgeführt, kann allerdings auch jede beliebige andere Form aufweisen, insbesondere rund oder zumindest abschnittsweise rund oder bogenförmig.It can also be seen in these representations that the
Der trichterförmige Leitereinführungsbereich 30 bildet dabei für einen einzusteckenden elektrischen Leiter 5, insbesondere für dessen abisoliertes Ende 6, eine Führung, so dass das abisolierte Ende zielgerichtet der Klemmstelle zugeführt werden kann. Die elektrische Anschlussklemme 1 ist auch für mehrdrähtige elektrische Leiter 5 verwendbar, insbesondere dann, wenn die durch die Klemmkanten 10 gebildete Klemmstelle durch ein Betätigungselement, welches als ein Drücker 21 ausgebildet ist, vor dem Einstecken des elektrischen Leiters 5 geöffnet wird. Die einzelnen Drähte des mehrdrähtigen Leiters 5 können auf Grund des umfangsseitig nahezu geschlossen Leitereinführungsbereiches 30 nicht ausweichen und werden sicher von der Klemmkante 10 klemmend gehalten. Das der Leitereinführungsöffnung 3 zugewande Ende des trichterförmigen Abschnitts des Leitereinführungsbereichs 30 mit dem größeren Querschnitt kann dabei auch, wenn erwünscht, als ein Anschlag für das den isolierten Abschnitt des elektrischen Leiters 5 dienen.The funnel-shaped
Dadurch, dass der trichterförmige Leitereinführungsbereich 30 zusammengesetzt ist aus dem Isolierstoffgehäuse 2 und dem Kontaktrahmen 4 bzw. von diesen beiden Baueilen gebildet wird, wird eine einfache und wirkungsvolle Leiterführung erzielt, wobei insbesondere der Kontaktrahmen 4 sehr einfach, kompakt und materialsparend ausgeführt werden kann.Characterized in that the funnel-shaped

Im nicht montierten Zustand befindet sich der Drückerarm 23 bzw. des äußere Oberfläche im Wesentlichen in der Ebene der Oberflächenkontur des Isolierstoffgehäuses 2, sowohl im Bereich der Gehäuseoberseite 18 als auch im Bereich der Gehäuserückseite 20. Im montierten mit dem im Isolierstoffgehäuse 2 eingesetzten Kontaktrahmen 4 und nicht betätigten Zustand steht der Drücker 21 dagegen zumindest gegenüber der Gehäuseoberseite 18 etwas heraus, wie dies in

Die
Die dargestellte winkelförmige Ausbildung des Drückers 21 ermöglicht einen verhältnismäßig langen wirksamen Drückerarm 23 mit einem dementsprechend langen Hebelarm, was insbesondere bei beengten Bauraumverhältnissen oder sehr kleinen elektrischen Anschlussklemmen mit kleinen Isolierstoffgehäusen von Vorteil ist. So wird es insbesondere bei miniaturisierten Anschlussklemmen durch die erfindungsgemäße Ausbildung des Drückers 21 überhaupt erst ermöglicht, einen wirksamen Drücker 21 für die Betätigung eines Kontaktrahmens 4 vorzusehen.The illustrated angular design of the
Dadurch, dass der Drückerarm 23 im unbetätigten Zustand einer Vorspannung unterworfen ist, kann die Spannung, mit welcher der Drückerarm 23 beaufschlagt wird, klein gehalten werden. Der Wert der Vorspannung ist relativ klein, da die Auslenkung des Drückerarms 23 im unbetätigten Zustand auch relativ klein ist. Die Auslenkung des Drückerarms 23 in der betätigten Stellung in das Isolierstoffgehäuse 2 hinein ist auch nicht Wesentlich viel größer als im unbetätigten Zustand, so dass die Spannungen, welcher der Drückerarm 23 unterworfen wird, auch verhältnismäßig klein gehalten werden können. Würde dagegen der gesamte Betätigungsweg auf einen spannungslosen Drückerarm 23 aufgegeben werden, wäre die auf den Drückerarm 23 wirkende Spannung wesentlich größer, so dass auch der Drückerarm 23 insgesamt größer dimensioniert werden müsste. Man erkennt also, dass mit der vorliegenden Anordnung des Drückers 21 innerhalb der Anschlussklemme 1 und dessen Zusammenwirken mit dem Kontaktrahmen 4, der Drücker 21 insgesamt sehr klein gehalten werden kann und damit insbesondere für sehr klein bauende Anschlussklemmen geeignet ist.Characterized in that the

Drückerarm realisiert werden. Durch die begrenzte Auslenkung der Blattfedern 9 kann zwischen zwei zueinander zugeordneten Blattfedern lediglich ein begrenzter Zwischenraum entstehen. Sofern die maximale Breite des Abschnitts des Drückerarms 23, welcher zwischen die Blattfedern 9 eintaucht größer ist als der Zwischenraum zwischen den maximal ausgelenkten Blattfedern 9, kann der Drückerarm 23 nur begrenzt ausgelenkt werden, so dass dieser auch keiner übermäßigen Belastung unterworfen werden kann und ein Brechen des Drückerarms 23 wirksam vermieden wird.Trigger arm can be realized.
