Definitions
- the invention relates to a terminal.
- Such a terminal is used for electrically contacting connecting a conductor.
- Such a terminal can be used for example on a circuit board as a so-called print terminal for connecting a conductor to the circuit board or as so-called terminal blocks for electrically connecting a plurality of conductors together.
- terminals of the type in question can be used for quite different purposes and in completely different embodiments.
- Such a connection terminal comprises a housing, an insertion opening arranged on the housing, into which a conductor can be inserted in a plug-in direction, and a contact element arranged on the housing, with which the conductor can be brought into contact by insertion into the insertion opening.
- a spring element is further arranged, which is held by a spring body to the housing and having an extending from the spring body, elastically adjustable spring legs.
- This spring leg is designed to clamp in a clamping position an inserted into the insertion opening conductor with the contact element such that the conductor is held in an electrically contacting manner on the contact element.
- the actuating element acts to adjust the spring leg to a remote from the spring body, the distal end of the spring leg.
- the actuating element has a shaft with a head, via which the actuating element can be actuated, and a leg section remote from the head, wherein the actuating element acts on the distal end of the spring leg via the foot section.
- the actuating element has at its foot portion on a contact projection which limits in cooperation with a projection of the housing a displacement of the actuating element against the actuating direction,
- an actuating element is arranged on the housing, which can be actuated in an actuating direction in order to adjust the spring leg out of the clamping position.
- the actuator is operable to release a conductor from the terminal.
- a terminal is known in which an actuating element at its projecting into the housing of the terminal end has a receiving area in which a resilient leg which is integrally connected to a current bar, is mounted and movable by a movement of the actuating element along an actuating direction.
- the object of the present invention is to further improve a connection terminal of this type.
- the actuating element in the region of its head a latching projection for latching with an associated latching projection of the housing in the open position, and that the actuating element is adjustable in the open position in a release direction transversely to the direction of actuation to the housing to release the latching between the actuating element and the housing.
- the actuating element acts on the distal end of the spring leg, the force effect between the actuating element and the spring leg and thus the feel upon actuation of the actuating element is improved.
- the actuating element acts on the spring element under a comparatively large lever, so that the force to be applied to the actuating element can be reduced.
- the interaction between actuator and spring leg can be further improved by the fact that the actuation direction along which the actuator is to be actuated, and the insertion, in which a conductor is to be inserted into the terminal, are directed obliquely to each other. Because of the spring leg is directed in the clamping position obliquely to the contact element, wherein the contact element preferably extends oblong along the insertion direction. By oblique orientation of the actuating direction to the insertion direction, the actuating element for adjusting the spring leg from the clamping position acting out approximately perpendicular to the spring leg. The spring leg and the actuating direction thus extend in the clamping position of the spring leg thus approximately perpendicular to each other.
- the actuating element passes through an opening of the contact element.
- the actuating element thus extends through the contact element, so that can be removed from the contact element by pressing on the contact element of the spring leg in an advantageous manner for pivoting the spring leg out of the clamping position.
- the actuating element comprises a shaft with a head, via which the actuating element can be actuated, and a foot section remote from the head.
- a foot section acts on the actuator the distal end of the spring leg, while a user over the head, for example manually or using a suitable tool, for. B. a screwdriver, can act on the actuator.
- the foot section preferably has a contact surface on a side facing the spring leg, via which the foot section is in contact with the spring leg.
- the foot portion may be adapted in its contact surface of the spring leg, so that the actuating element on the foot portion in an adjustment of the spring leg out of the clamping position and a thus accompanying pivoting of the spring leg relative to the spring body held on the housing can act in a favorable manner on the spring leg.
- the actuating element is locked in the open position of the terminal in which the spring leg is moved out of the clamping position with the housing, so that the actuating element is held in its assumed position and the spring leg is thus fixed in the open position.
- the actuating element has on its head a latching projection which can be brought into latching engagement with an associated latching projection of the housing.
- the attachment of the locking projection of the actuating element on the head - ie at the end remote from the foot portion of the actuating element - has the consequence that acts between the foot portion and the head, a large lever which allows easy release of the locking between the actuator and the housing.
- the actuating element can be pivoted about the advantageously rounded foot portion around the spring leg, in this way to bring the locking projection of the actuating element without great force disengaged from the locking projection of the housing.
- the actuating element has at its foot portion on a contact projection which limits in cooperation with a projection of the housing an adjustment of the actuating element against the actuation direction.
- the abutment projection of the foot portion In the clamping position of the spring leg, so when not actuated actuator, the abutment projection of the foot portion is advantageously in contact with the associated projection of the housing, so that the actuating element is in a defined position on the housing.
- the abutment projection of the foot portion is removed from the associated projection of the housing, so that in the open position of the abutment projection is not in contact with the projection.
- the abutment projection on the foot portion of the actuating element and the latching projection on the head of the actuating element are arranged on different sides of the actuating element.
- the latching projection is formed on a (with respect to the actuating direction) opposite, the second side of the actuating element.
- the spring leg By actuating the actuating element, the spring leg is pivoted out of its clamping position. This is done under elastic tension of the spring leg, which causes in the open position of the spring leg exerts a restoring spring force on the actuating element.
- This spring force acting in the open position is preferably directed obliquely to the actuation direction by a direction vector component of the restoring spring force against the actuation direction and a further, second direction vector component of the spring force acting transversely to the actuation direction.
- the direction vector components are to be understood as meaning the vector components of the spring force.
- the spring force is directed and thus represents a vector that can be decomposed into vector components. Characterized in that a direction vector component acts counter to the actuation direction, the restoring spring force causes an extraction of the actuating element against the actuating direction of the housing when the latch between the actuating element and the housing is released.
- the directional vector component acting transversely to the actuating direction acts on actuation of the actuating element for transferring the spring leg in the open position preferably in the direction of latching engagement of the actuating element with the housing, so that the locking of the actuating element with the housing made in an automatic manner and in the open position the spring leg is held in a locking manner.
- a user can act on the actuating element in a direction of release directed transversely to the direction of actuation, wherein this can be done manually or using a tool.
- By acting on the actuating element of the locking projection of the actuating element is pushed out of engagement with the associated locking projection of the housing, which advantageously takes place under rolling of the foot portion of the actuating element on the spring leg and thus under pivoting of the actuating element in the housing.
- Fig. 1 shows a schematic view of an embodiment of a terminal 1, which has a housing 10 with formed on a housing surface 100 insertion openings 101 for connecting one or more electrical conductors 2.
- an electrical conductor 2 can be inserted into each insertion opening 101 with a line end 20 in a plug-in direction E to be electrically contacted within the housing 10 and electrically connected thereto, for example, with a printed circuit board to which the terminal 1 is connected.
- Fig. 2A to 2C show sectional views taken along a line II of FIG Fig. 1
- a spring element 12 is arranged in the form of a leg spring and held with a spring body 120 to a spring holder 102 so stationary and rotationally fixed to the housing 10 that the spring body 120 is fixed to the housing 10, but a spring leg 121 extended by the spring body 120 can be pivoted within a space 103 of the housing 10.
- the spring leg 121 of the spring element 12 serves to insert an inserted into an insertion opening 101 line end 20 of a conductor 2 in an electrically contacting manner to jam with a metallic, electrically-conductive contact element 13.
- the contact element 13 is fixedly arranged within the housing 10 and extends with a clamping surface 131 approximately along the insertion direction E within the housing 10.
- the spring element 12 with its spring leg 121 can assume different positions within the housing 10. In a clamping position, shown in Fig. 2A , the spring leg 121 of the clamping surface 131 of the contact element 13 is approximated. In this clamping position, the spring leg 121 strives when a conductor 2 is inserted with a line end 20 in the housing 10, so that the line end 20 between the spring leg 121 and the clamping surface 131 of the contact element 13 is clamped.
- the spring leg 121 can be pivoted by an arranged on the housing 10 actuator 11 from its clamping position.
- the actuating element 11 is adjustably arranged along an actuating direction B on the housing 10 and has a shaft 11 which is arranged with a foot portion 112 within the space 103 of the housing 10 and protrudes with a head 115 from the housing 10.
- the actuating element 11 is designed to act with its foot portion 112 on a remote from the spring body 120, the distal end 122 of the spring leg 121.
- a user can act in the direction of actuation B on the actuating element 11 and this example, manually or using a suitable tool, for. B. a screwdriver, push into the housing 10.
- a suitable tool for. B. a screwdriver
- the actuating element 11 presses with its foot portion 112 on the distal end 122 of the spring leg 121, so that the spring leg 121 is pivoted about the spring holder 102 around and removed from the contact element 13, as shown in FIG Fig. 2B is shown.
- a latching projection 111 is formed, which engages upon actuation of the actuating element 11 in the operating direction B with an associated latching projection 105 on the housing 10, as shown in FIG Fig. 2B is shown.
- the actuating element 11 is latched after insertion into the housing 10 with the housing 10, so that the actuating element 11 remains in the assumed position and holds the spring leg 121 in this open position of the terminal 1.
- the actuator 11 can be released from its latching by means of a suitable tool 3 or manually in a direction transverse to the direction B direction of loosening L on a release tab 116th the actuating element 11 is acted upon.
- the latching projection 111 on the head 115 of the actuating element 11 can be disengaged from the associated latching projection 105 on the housing 10, as shown in FIG Fig. 2C is shown, so that the actuating element 11 is exposed due to the force acting through the spring leg 121 return spring force F against the direction of actuation B from the housing 10.
- actuation of the actuating element 10 in the operating direction B of the spring leg 121 is adjusted within the housing 10 and thereby stretched elastically.
- the actuation of the actuating element 11 thus takes place counter to the spring force of the spring leg 121. Because the actuating element 11 acts with its foot portion 112 on the distal end 122 of the spring leg 121, however comparatively small forces are required for adjusting the spring leg 121, so that the by a user applied force to actuate the actuating element 11 is comparatively low.
- the required force is further reduced by the fact that the operating direction B is directed at least approximately perpendicular to the extension direction of the spring leg 121 in the clamping position, as is apparent from Fig. 2A is apparent.
- the actuating element 11 acts upon actuation under favorable lever conditions on the spring leg 121.
- a first direction vector component V1 in this case acts counter to the direction of actuation B, while another, second direction vector component V2 is directed transversely to the direction of actuation B.
- the transverse direction vector component V2 in this case acts in such a way that it loads the actuating element 11 in the direction of bringing the latching projection 111 on the head 115 into engagement with the associated latching projection 105 on the housing 10. This supports at least the production of the locking of the actuating element 11 with the housing 10 and also causes a locking of the actuating element 11 in its latched position, so that the latch can not readily, in particular not automatically solved.
- the foot portion 112 is rounded at its contact surface 114 or shaped so that it is adapted to the bent shape at the distal end 122 of the spring leg 121. As a result, an advantageous contact of the foot portion 112 at the distal end 122 along the entire displacement of the spring leg 121 is achieved.
- the contact surface 114 also represents a tilting point of the actuating element 11, around which the actuating element 11 can be tilted to release the latch, as shown in FIG Fig. 2C is shown. Also, the release of the catch can be made so with little effort in haptic pleasant way.
- the foot portion 112 of the actuating element 11 is hook-shaped and has a contact projection 113 which, opposite to the actuating direction B, has an associated projection 104 on the housing 10.
- this investment projection 104 is in abutment with the associated projection 113 on the side of the housing 10, so that the actuating element 11 is in a defined position on the housing 10, over which the actuating element 11 can not be moved out of the housing 10 out.
- the action of the actuating element 11 under favorable leverage conditions on the in the clamping position at least approximately at right angles to the direction of actuation B extended spring leg 121 is possible because the plug-in direction E, in which a conductor 2 is inserted with its line end 20 in the housing 10, obliquely to Direction of actuation B is directed, as is made Fig. 2A is apparent.
- the angle between the operating direction B and the insertion direction E for example, between 30 ° and 60 °, for example, be 45 °.
- the actuating element 11 is intended to push away the spring limb 121 from the clamping surface 131, which is also oblique to the direction of actuation B, it is necessary for the actuating element 11 to reach through the contact element 13 at an opening 130, so that the actuating element 11 engages the actuating direction B beyond the contact element 13 located spring leg 121 can act.
- the actuating element 11 is in this case outside an insertion path of a conductor 2, so that a conductor 2 can be inserted with its line end 20 past the actuating element 11 into the housing 10, as in Fig. 2C is illustrated.
- Fig. 3 shows a schematic view of an embodiment of a spring element 12 in cooperation with an actuating element 11.
- a spring element 12 may for example be associated with two insertion openings 101 for clamping connection of two conductors 2 at a terminal 1.

Description
Die Erfindung betrifft eine Anschlussklemme.The invention relates to a terminal.
Eine solche Anschlussklemme dient zum elektrisch kontaktierenden Anschließen eines Leiters. Eine solche Anschlussklemme kann beispielsweise an einer Leiterplatte als sogenannte Printklemme zum Anschließen eines Leiters an die Leiterplatte oder als sogenannte Reihenklemmen zum elektrischen Verbinden mehrerer Leiter miteinander eingesetzt werden. Grundsätzlich können Anschlussklemmen der hier betroffenen Art zu ganz unterschiedlichen Zwecken und in ganz unterschiedlichen Ausführungsformen Verwendung finden.Such a terminal is used for electrically contacting connecting a conductor. Such a terminal can be used for example on a circuit board as a so-called print terminal for connecting a conductor to the circuit board or as so-called terminal blocks for electrically connecting a plurality of conductors together. In principle, terminals of the type in question can be used for quite different purposes and in completely different embodiments.
Eine derartige Anschlussklemme umfasst ein Gehäuse, eine an dem Gehäuse angeordnete Einstecköffnung, in die ein Leiter in eine Einsteckrichtung eingesteckt werden kann, und ein an dem Gehäuse angeordnetes Kontaktelement, mit dem der Leiter durch Einstecken in die Einstecköffnung in Kontakt bringbar ist. An dem Gehäuse ist weiter ein Federelement angeordnet, das über einen Federkörper an dem Gehäuse gehalten ist und einen sich von dem Federkörper erstreckenden, elastisch verstellbaren Federschenkel aufweist. Dieser Federschenkel ist ausgebildet, in einer Klemmstellung einen in die Einstecköffnung eingesteckten Leiter mit dem Kontaktelement derart zu verklemmen, dass der Leiter in elektrisch kontaktierender Weise an dem Kontaktelement gehalten ist. Das Betätigungselement wirkt zum Verstellen des Federschenkels auf ein von dem Federkörper abliegendes, distales Ende des Federschenkels ein. Das Betätigungselement weist einen Schaft mit einem Kopf, über den das Betätigungselement betätigbar ist, und einem von dem Kopf abliegenden Fußabschnitt auf, wobei das Betätigungselement über den Fußabschnitt auf das distale Ende des Federschenkels einwirkt. Das Betätigungselement weist an seinem Fußabschnitt einen Anlagevorsprung auf, der in Zusammenwirken mit einem Vorsprung des Gehäuses einen Verstellweg des Betätigungselements entgegen der Betätigungsrichtung begrenzt,Such a connection terminal comprises a housing, an insertion opening arranged on the housing, into which a conductor can be inserted in a plug-in direction, and a contact element arranged on the housing, with which the conductor can be brought into contact by insertion into the insertion opening. On the housing, a spring element is further arranged, which is held by a spring body to the housing and having an extending from the spring body, elastically adjustable spring legs. This spring leg is designed to clamp in a clamping position an inserted into the insertion opening conductor with the contact element such that the conductor is held in an electrically contacting manner on the contact element. The actuating element acts to adjust the spring leg to a remote from the spring body, the distal end of the spring leg. The actuating element has a shaft with a head, via which the actuating element can be actuated, and a leg section remote from the head, wherein the actuating element acts on the distal end of the spring leg via the foot section. The actuating element has at its foot portion on a contact projection which limits in cooperation with a projection of the housing a displacement of the actuating element against the actuating direction,
Um ein einfaches, eine geringe Kraft erforderndes Einsetzen eines Leiters in die Einstecköffnung zu ermöglichen, ist an dem Gehäuse ein Betätigungselement angeordnet, das in eine Betätigungsrichtung betätigt werden kann, um den Federschenkel aus der Klemmstellung heraus zu verstellen. Durch Betätigung des Betätigungselements kann der Federschenkel somit von dem Kontaktelement entfernt werden, so dass ein Leiter ohne weiteres und ohne großen Kraftaufwand in die Einstecköffnung in eine Lage zwischen dem Kontaktelement und dem Federschenkel geschoben werden kann und über den Federschenkel mit dem Kontaktelement verklemmt werden kann.In order to enable a simple, low force insertion of a conductor into the insertion opening, an actuating element is arranged on the housing, which can be actuated in an actuating direction in order to adjust the spring leg out of the clamping position. By actuating the actuating element of the spring leg can thus be removed from the contact element, so that a conductor readily and without much effort into the insertion in a position between the contact element and the spring leg can be pushed and can be clamped on the spring leg with the contact element.
Ebenso ist das Betätigungselement betätigbar, um einen Leiter von der Anschlussklemme zu lösen. Durch Entfernen des Federschenkels von dem Kontaktelement und durch Aufhebung der Klemmverbindung kann der Leiter ohne weiteres aus der Einstecköffnung herausgezogen werden.Likewise, the actuator is operable to release a conductor from the terminal. By removing the spring leg from the contact element and by removing the clamp connection, the conductor can be easily pulled out of the insertion.
Weil umständlich sein kann, ein Betätigungselement manuell oder unter Verwendung eines geeigneten Werkzeugs in Position zu halten, um einen Leiter an die Anschlussklemme anzusetzen, ist bei einer aus der
Aus der
Aufgabe der vorliegenden Erfindung ist es, eine Anschlussklemme dieser Art weiter zu verbessern.The object of the present invention is to further improve a connection terminal of this type.
Diese Aufgabe wird gelöst durch eine Anschlussklemme mit den Merkmalen des Anspruchs 1.This object is achieved by a terminal with the features of claim 1.
Demnach ist vorgesehen, dass das Betätigungselement im Bereich seines Kopfes einen Rastvorsprung zum Verrasten mit einem zugeordneten Rastvorsprung des Gehäuses in der geöffneten Stellung aufweist, und dass das Betätigungselement in der geöffneten Stellung in eine Löserichtung quer zur Betätigungsrichtung zu dem Gehäuse verstellbar ist, um die Verrastung zwischen dem Betätigungselement und dem Gehäuse zu lösen.Accordingly, it is provided that the actuating element in the region of its head a latching projection for latching with an associated latching projection of the housing in the open position, and that the actuating element is adjustable in the open position in a release direction transversely to the direction of actuation to the housing to release the latching between the actuating element and the housing.
Dadurch, dass das Betätigungselement auf das distale Ende des Federschenkels einwirkt, ist die Kraftwirkung zwischen dem Betätigungselement und dem Federschenkel und damit auch die Haptik bei Betätigung des Betätigungselements verbessert. Insbesondere wirkt das Betätigungselement dadurch, dass es auf das distale, vom Federkörper abliegende Ende des Federschenkels einwirkt, unter einem vergleichsweise großen Hebel auf das Federelement ein, so dass die am Betätigungselement aufzubringende Kraft reduziert sein kann.The fact that the actuating element acts on the distal end of the spring leg, the force effect between the actuating element and the spring leg and thus the feel upon actuation of the actuating element is improved. In particular, by acting on the distal end of the spring leg remote from the spring body, the actuating element acts on the spring element under a comparatively large lever, so that the force to be applied to the actuating element can be reduced.
Weil der Einwirkungspunkt zwischen Betätigungselement und Federschenkel am distalen Ende liegt, ist auch die Beanspruchung des Federelements, insbesondere des Federschenkels, reduziert.Because the point of action between the actuating element and spring leg lies at the distal end, the stress on the spring element, in particular the spring leg, is reduced.
Das Zusammenwirken zwischen Betätigungselement und Federschenkel kann weiter dadurch verbessert werden, dass die Betätigungsrichtung, entlang derer das Betätigungselement zu betätigen ist, und die Einsteckrichtung, in die ein Leiter in die Anschlussklemme einzustecken ist, schräg zueinander gerichtet sind. Denn der Federschenkel ist in der Klemmstellung schräg zum Kontaktelement gerichtet, wobei sich das Kontaktelement vorzugsweise länglich entlang der Einsteckrichtung erstreckt. Durch schräge Ausrichtung der Betätigungsrichtung zur Einsteckrichtung kann das Betätigungselement zum Verstellen des Federschenkels aus der Klemmstellung heraus in etwa senkrecht auf den Federschenkel einwirken. Der Federschenkel und die Betätigungsrichtung erstrecken sich in der Klemmstellung des Federschenkels somit in etwa senkrecht zueinander.The interaction between actuator and spring leg can be further improved by the fact that the actuation direction along which the actuator is to be actuated, and the insertion, in which a conductor is to be inserted into the terminal, are directed obliquely to each other. Because of the spring leg is directed in the clamping position obliquely to the contact element, wherein the contact element preferably extends oblong along the insertion direction. By oblique orientation of the actuating direction to the insertion direction, the actuating element for adjusting the spring leg from the clamping position acting out approximately perpendicular to the spring leg. The spring leg and the actuating direction thus extend in the clamping position of the spring leg thus approximately perpendicular to each other.
Hierbei kann vorteilhaft sein, dass das Betätigungselement eine Öffnung des Kontaktelements durchgreift. Das Betätigungselement erstreckt sich somit durch das Kontaktelement hindurch, so dass durch Drücken auf das Kontaktelement der Federschenkel in vorteilhafter Weise zum Verschwenken des Federschenkels aus der Klemmstellung heraus von dem Kontaktelement entfernt werden kann.It may be advantageous that the actuating element passes through an opening of the contact element. The actuating element thus extends through the contact element, so that can be removed from the contact element by pressing on the contact element of the spring leg in an advantageous manner for pivoting the spring leg out of the clamping position.
In der erfindungsgemäßen Ausgestaltung umfasst das Betätigungselement einen Schaft mit einem Kopf, über den das Betätigungselement betätigbar ist, und einem von dem Kopf abliegenden Fußabschnitt. Über den Fußabschnitt wirkt das Betätigungselement auf das distale Ende des Federschenkels ein, während ein Nutzer über den Kopf, beispielsweise manuell oder unter Verwendung eines geeigneten Werkzeugs, z. B. eines Schraubendrehers, auf das Betätigungselement einwirken kann.In the embodiment according to the invention, the actuating element comprises a shaft with a head, via which the actuating element can be actuated, and a foot section remote from the head. About the foot section acts on the actuator the distal end of the spring leg, while a user over the head, for example manually or using a suitable tool, for. B. a screwdriver, can act on the actuator.
Zum günstigen Einwirken auf den Federschenkel weist der Fußabschnitt vorzugsweise an einer dem Federschenkel zugewandten Seite eine Anlagefläche auf, über die der Fußabschnitt mit dem Federschenkel in Anlage ist. Durch geeignete Abrundung des Fußabschnitts (betrachtet im Querschnitt in einer Schwenkebene, in der der Federschenkel verschwenkbar ist) kann der Fußabschnitt in seiner Anlagefläche dem Federschenkel angepasst sein, so dass das Betätigungselement über den Fußabschnitt bei einem Verstellen des Federschenkels aus der Klemmstellung heraus und einem damit einhergehenden Verschwenken des Federschenkels relativ zu dem an dem Gehäuse gehaltenen Federkörper in günstiger Weise auf den Federschenkel einwirken kann.For a favorable effect on the spring leg, the foot section preferably has a contact surface on a side facing the spring leg, via which the foot section is in contact with the spring leg. By suitable rounding of the foot portion (considered in cross-section in a pivot plane in which the spring leg is pivotable), the foot portion may be adapted in its contact surface of the spring leg, so that the actuating element on the foot portion in an adjustment of the spring leg out of the clamping position and a thus accompanying pivoting of the spring leg relative to the spring body held on the housing can act in a favorable manner on the spring leg.
Das Betätigungselement ist in der geöffneten Stellung der Anschlussklemme, in der der Federschenkel aus der Klemmstellung heraus verstellt ist, mit dem Gehäuse verrastbar, so dass das Betätigungselement in seiner eingenommenen Stellung gehalten und der Federschenkel somit in der geöffneten Stellung fixiert ist. Zum Verrasten des Betätigungselements mit dem Gehäuse weist das Betätigungselement an seinem Kopf einen Rastvorsprung auf, der rastend mit einem zugeordneten Rastvorsprung des Gehäuses in Eingriff gebracht werden kann. Bei Betätigung des Betätigungselements zum Verstellen des Federschenkels in die geöffnete Stellung gelangt der Rastvorsprung am Kopf des Betätigungselements rastend in Eingriff mit dem Rastvorsprung am Gehäuse, so dass das Betätigungselement mit dem Gehäuse verriegelt und darüber der Federschenkel in der geöffneten Stellung gehalten wird.The actuating element is locked in the open position of the terminal in which the spring leg is moved out of the clamping position with the housing, so that the actuating element is held in its assumed position and the spring leg is thus fixed in the open position. For locking the actuating element to the housing, the actuating element has on its head a latching projection which can be brought into latching engagement with an associated latching projection of the housing. Upon actuation of the actuating element for adjusting the spring leg in the open position of the locking projection on the head of the actuating element is latchingly engages with the locking projection on the housing, so that the actuating element is locked to the housing and above the spring leg is held in the open position.
Das Anbringen des Rastvorsprungs des Betätigungselements am Kopf - also an dem vom Fußabschnitt abliegenden Ende des Betätigungselements - hat zur Folge, dass zwischen dem Fußabschnitt und dem Kopf ein großer Hebel wirkt, der ein leichtes Lösen der Verrastung zwischen dem Betätigungselement und dem Gehäuse ermöglicht. So kann zum Lösen der Verrastung des Betätigungselements mit dem Gehäuse das Betätigungselement um den vorteilhafterweise abgerundeten Fußabschnitt herum an dem Federschenkel verschwenkt werden, um auf diese Weise den Rastvorsprung des Betätigungselements ohne großen Kraftaufwand außer Eingriff von dem Rastvorsprung des Gehäuses zu bringen.The attachment of the locking projection of the actuating element on the head - ie at the end remote from the foot portion of the actuating element - has the consequence that acts between the foot portion and the head, a large lever which allows easy release of the locking between the actuator and the housing. Thus, to release the locking of the actuating element with the housing, the actuating element can be pivoted about the advantageously rounded foot portion around the spring leg, in this way to bring the locking projection of the actuating element without great force disengaged from the locking projection of the housing.
Das Betätigungselement weist an seinem Fußabschnitt einen Anlagevorsprung auf, der im Zusammenwirken mit einem Vorsprung des Gehäuses einen Verstellweg des Betätigungselements entgegen der Betätigungsrichtung begrenzt. In der Klemmstellung des Federschenkels, also bei nicht betätigtem Betätigungselement, liegt der Anlagevorsprung des Fußabschnitts vorteilhafterweise in Anlage mit dem zugeordneten Vorsprung des Gehäuses, so dass das Betätigungselement sich in einer definierten Lage an dem Gehäuse befindet. Durch Betätigen des Betätigungselements in Betätigungsrichtung wird der Anlagevorsprung des Fußabschnitts von dem zugeordneten Vorsprung des Gehäuses entfernt, so dass in der geöffneten Stellung der Anlagevorsprung nicht in Anlage mit dem Vorsprung ist.The actuating element has at its foot portion on a contact projection which limits in cooperation with a projection of the housing an adjustment of the actuating element against the actuation direction. In the clamping position of the spring leg, so when not actuated actuator, the abutment projection of the foot portion is advantageously in contact with the associated projection of the housing, so that the actuating element is in a defined position on the housing. By actuating the actuating element in the actuating direction, the abutment projection of the foot portion is removed from the associated projection of the housing, so that in the open position of the abutment projection is not in contact with the projection.
In einer weiteren vorteilhaften Ausführungsform sind der Anlagevorsprung am Fußabschnitt des Betätigungselements und der Rastvorsprung am Kopf des Betätigungselements an unterschiedlichen Seiten des Betätigungselements angeordnet. Während der Anlagevorsprung an einer ersten Seite des Betätigungselements angeordnet ist, ist der Rastvorsprung an einer (mit Bezug auf die Betätigungsrichtung) gegenüberliegenden, zweiten Seite des Betätigungselements ausgebildet.In a further advantageous embodiment, the abutment projection on the foot portion of the actuating element and the latching projection on the head of the actuating element are arranged on different sides of the actuating element. During the abutment on a first side of the actuator is arranged, the latching projection is formed on a (with respect to the actuating direction) opposite, the second side of the actuating element.
Durch Betätigung des Betätigungselements wird der Federschenkel aus seiner Klemmstellung heraus verschwenkt. Dies erfolgt unter elastischer Verspannung des Federschenkels, was bewirkt, dass in der geöffneten Stellung der Federschenkel eine rückstellende Federkraft auf das Betätigungselement ausübt. Diese in der geöffneten Stellung wirkende Federkraft ist vorzugsweise schräg zur Betätigungsrichtung gerichtet, indem eine Richtungsvektorkomponente der rückstellenden Federkraft entgegen der Betätigungsrichtung und eine weitere, zweite Richtungsvektorkomponente der Federkraft quer zur Betätigungsrichtung wirkt.By actuating the actuating element, the spring leg is pivoted out of its clamping position. This is done under elastic tension of the spring leg, which causes in the open position of the spring leg exerts a restoring spring force on the actuating element. This spring force acting in the open position is preferably directed obliquely to the actuation direction by a direction vector component of the restoring spring force against the actuation direction and a further, second direction vector component of the spring force acting transversely to the actuation direction.
Unter den Richtungsvektorkomponenten sind in diesem Zusammenhang die Vektorkomponenten der Federkraft zu verstehen. Die Federkraft ist gerichtet und stellt somit einen Vektor dar, der in Vektorkomponenten zerlegt werden kann. Dadurch, dass eine Richtungsvektorkomponente entgegen der Betätigungsrichtung wirkt, bewirkt die rückstellende Federkraft ein Herausstellen des Betätigungselements entgegen der Betätigungsrichtung aus dem Gehäuse, wenn die Verrastung zwischen dem Betätigungselement und dem Gehäuse gelöst wird.In this context, the direction vector components are to be understood as meaning the vector components of the spring force. The spring force is directed and thus represents a vector that can be decomposed into vector components. Characterized in that a direction vector component acts counter to the actuation direction, the restoring spring force causes an extraction of the actuating element against the actuating direction of the housing when the latch between the actuating element and the housing is released.
Die quer zur Betätigungsrichtung wirkende Richtungsvektorkomponente hingegen wirkt bei Betätigung des Betätigungselements zum Überführen des Federschenkels in die geöffnete Stellung vorzugsweise in Richtung des rastenden Ineingriffbringens des Betätigungselements mit dem Gehäuse, so dass die Verrastung des Betätigungselements mit dem Gehäuse in selbsttätiger Weise hergestellt und in der geöffneten Stellung des Federschenkels in arretierender Weise gehalten wird.The directional vector component acting transversely to the actuating direction, however, acts on actuation of the actuating element for transferring the spring leg in the open position preferably in the direction of latching engagement of the actuating element with the housing, so that the locking of the actuating element with the housing made in an automatic manner and in the open position the spring leg is held in a locking manner.
Zum Lösen des Betätigungselements aus seiner Verrastung mit dem Gehäuse kann ein Nutzer in eine quer zur Betätigungsrichtung gerichtete Löserichtung auf das Betätigungselement einwirken, wobei dies manuell oder unter Verwendung eines Werkzeugs erfolgen kann. Durch Einwirken auf das Betätigungselement wird der Rastvorsprung des Betätigungselements außer Eingriff mit dem zugeordneten Rastvorsprung des Gehäuses geschoben, wobei dies vorteilhafterweise unter Abrollen des Fußabschnitts des Betätigungselements am Federschenkel und somit unter Verschwenken des Betätigungselements im Gehäuse erfolgt.To release the actuating element from its latching with the housing, a user can act on the actuating element in a direction of release directed transversely to the direction of actuation, wherein this can be done manually or using a tool. By acting on the actuating element of the locking projection of the actuating element is pushed out of engagement with the associated locking projection of the housing, which advantageously takes place under rolling of the foot portion of the actuating element on the spring leg and thus under pivoting of the actuating element in the housing.

Der Federschenkel 121 des Federelements 12 dient dazu, ein in eine Einstecköffnung 101 eingestecktes Leitungsende 20 eines Leiters 2 in elektrisch kontaktierender Weise mit einem metallischen, elektrisch-leitfähigen Kontaktelement 13 zu verklemmen. Das Kontaktelement 13 ist fest innerhalb des Gehäuses 10 angeordnet und erstreckt sich mit einer Klemmfläche 131 in etwa entlang der Einsteckrichtung E innerhalb des Gehäuses 10.The
Das Federelement 12 mit seinem Federschenkel 121 kann unterschiedliche Stellungen innerhalb des Gehäuses 10 einnehmen. In einer Klemmstellung, dargestellt in
Um einen Leiter 2 mit seinem Leitungsende 20 in einfacher Weise ohne großen Kraftaufwand in das Gehäuse 10 einstecken zu können, kann der Federschenkel 121 durch ein an dem Gehäuse 10 angeordnetes Betätigungselement 11 aus seiner Klemmstellung heraus verschwenkt werden. Das Betätigungselement 11 ist entlang einer Betätigungsrichtung B verstellbar an dem Gehäuse 10 angeordnet und weist einen Schaft 11 auf, der mit einem Fußabschnitt 112 innerhalb des Raums 103 des Gehäuses 10 angeordnet ist und mit einem Kopf 115 aus dem Gehäuse 10 herausragt.In order to insert a
Das Betätigungselement 11 ist dazu ausgebildet, mit seinem Fußabschnitt 112 auf ein von dem Federkörper 120 abliegendes, distales Ende 122 des Federschenkels 121 einzuwirken. Hierzu weist der Fußabschnitt 112 an einer dem Federschenkel 121 zugewandten Seite eine Anlagefläche 114 auf, die mit dem distalen Ende 122 des Federschenkels 121 in Kontakt steht.The
Um den Federschenkel 121 aus seiner Klemmstellung heraus zu verstellen, kann ein Nutzer in die Betätigungsrichtung B auf das Betätigungselement 11 einwirken und dieses beispielsweise manuell oder unter Verwendung eines geeigneten Werkzeugs, z. B. eines Schraubendrehers, in das Gehäuse 10 hineindrücken. Dadurch drückt das Betätigungselement 11 mit seinem Fußabschnitt 112 auf das distale Ende 122 des Federschenkels 121, so dass der Federschenkel 121 um die Federhalterung 102 herum verschwenkt und von dem Kontaktelement 13 entfernt wird, wie dies in
Am Kopf 115 des Betätigungselements 11 ist ein Rastvorsprung 111 ausgebildet, der bei Betätigung des Betätigungselements 11 in die Betätigungsrichtung B mit einem zugeordneten Rastvorsprung 105 am Gehäuse 10 in Eingriff gelangt, wie dies in
Weil der Federschenkel 121 in dieser Stellung von der Klemmfläche 131 des Kontaktelements 13 entfernt ist, kann ein Leiter 2 mit seinem Leitungsende 20 ohne weiteres durch eine Einstecköffnung 101 des Gehäuses 10 in das Gehäuse 10 eingesteckt werden, wie dies in
Um den Leiter 2 mit seinem Leitungsende 20 nach Einstecken innerhalb des Gehäuses 10 zu verklemmen, kann sodann das Betätigungselement 11 aus seiner Verrastung gelöst werden, indem mittels eines geeigneten Werkzeugs 3 oder auch manuell in eine quer zur Betätigungsrichtung B gerichtete Löserichtung L auf eine Löselasche 116 des Betätigungselements 11 eingewirkt wird. Dadurch kann der Rastvorsprung 111 am Kopf 115 des Betätigungselements 11 außer Eingriff mit dem zugeordneten Rastvorsprung 105 am Gehäuse 10 gebracht werden, wie dies in
Beim Betätigen des Betätigungselements 10 in die Betätigungsrichtung B wird der Federschenkel 121 innerhalb des Gehäuses 10 verstellt und dadurch elastisch gespannt. Das Betätigen des Betätigungselements 11 erfolgt somit entgegen der Federkraft des Federschenkels 121. Weil das Betätigungselement 11 mit seinem Fußabschnitt 112 auf das distale Ende 122 des Federschenkels 121 einwirkt, sind jedoch vergleichsweise geringe Kräfte zum Verstellen des Federschenkels 121 erforderlich, so dass der durch einen Nutzer aufzubringende Kraftaufwand zum Betätigen des Betätigungselements 11 vergleichsweise gering ist.Upon actuation of the
Der erforderliche Kraftaufwand wird weiter dadurch reduziert, dass die Betätigungsrichtung B zumindest näherungsweise senkrecht zur Erstreckungsrichtung des Federschenkels 121 in der Klemmstellung gerichtet ist, wie dies aus
Bei Verstellen des Federschenkels 121 in seine geöffnete Stellung, wie sie in
Der Fußabschnitt 112 ist an seiner Anlagefläche 114 abgerundet bzw. so geformt, dass er der abgeknickten Formgebung am distalen Ende 122 des Federschenkels 121 angepasst ist. Hierdurch wird eine vorteilhafte Anlage des Fußabschnitts 112 am distalen Ende 122 entlang des gesamten Verstellwegs des Federschenkels 121 erreicht.The
Die Anlagefläche 114 stellt zudem einen Kipppunkt des Betätigungselements 11 dar, um den herum das Betätigungselement 11 zum Lösen der Verrastung verkippt werden kann, wie dies in
Um den Verstellweg des Betätigungselements 11 entgegen der Betätigungsrichtung B zu begrenzen, ist der Fußabschnitt 112 des Betätigungselements 11 hakenförmig ausgebildet und weist einen Anlagevorsprung 113 auf, der entgegen der Betätigungsrichtung B hin zu einem zugeordneten Vorsprung 104 an dem Gehäuse 10 weist. In der Klemmstellung des Federschenkels 121, dargestellt in
Das Einwirken des Betätigungselements 11 unter günstigen Hebelverhältnissen auf den in der Klemmstellung zumindest näherungsweise unter rechtem Winkel zur Betätigungsrichtung B erstreckten Federschenkel 121 wird möglich, weil die Einsteckrichtung E, in die ein Leiter 2 mit seinem Leitungsende 20 in das Gehäuse 10 einzustecken ist, schräg zur Betätigungsrichtung B gerichtet ist, wie dies aus
Weil das Betätigungselement 11 den Federschenkel 121 von der ebenfalls schräg zur Betätigungsrichtung B erstreckten Klemmfläche 131 wegdrücken soll, ist erforderlich, dass das Betätigungselement 11 das Kontaktelement 13 an einer Öffnung 130 durchgreift, so dass das Betätigungselement 11 auf den in Betätigungsrichtung B jenseits des Kontaktelements 13 gelegenen Federschenkel 121 einwirken kann.Because the
Das Betätigungselement 11 befindet sich hierbei außerhalb eines Einsteckwegs eines Leiters 2, so dass ein Leiter 2 mit seinem Leitungsende 20 an dem Betätigungselement 11 vorbei in das Gehäuse 10 eingesteckt werden kann, wie dies in
Der der Erfindung zugrunde liegende Gedanke ist nicht auf die vorangehend geschilderten Ausführungsbeispiele beschränkt, sondern lässt sich auch in gänzlich anders gearteter Weise verwirklichen.The idea underlying the invention is not limited to the embodiments described above, but can also be realized in a completely different kind of way.
Eine Anschlussklemme der hier beschriebenen Art lässt sich beispielsweise an einer Leiterplatte zum Anschließen eines Leiters an die Leiterplatte verwenden. Die Anschlussklemme kann dabei eine oder auch mehrere Einstecköffnungen aufweisen.A terminal of the type described here can be used, for example, on a printed circuit board for connecting a conductor to the printed circuit board. The terminal may have one or more insertion openings.
Ebenso ist denkbar, eine Anschlussklemme in Form einer sogenannten Reihenklemme zum Verbinden mehrerer Leiter miteinander einzusetzen.It is also conceivable to use a terminal in the form of a so-called terminal block for connecting a plurality of conductors together.
