Definitions
- the present invention relates to spring-loaded connections and circular connectors with a large number of spring-loaded connections.
- the DE 10 2010 048 698 A1 describes an electrical connection terminal with an insulating material housing and with a spring clamp connection arranged therein, the spring clamp connection having a cage tension spring which has a contact leg resting on a busbar section, an adjoining rear spring arch and an actuating leg, the actuating leg being bent over in the direction of the busbar section Clamping section has a window recess through which the busbar section is passed and whose lower crossbar forms a clamping point for clamping an electrical conductor between the crossbar and the busbar section, and wherein a tab extends from the actuating leg forwards and outwards in the direction opposite to the rear spring arch protrudes, the spring clamp connection having an actuating lever which is pivotally mounted in front of the clamping section of the actuating leg of the cage tension spring adjacent to the tab and has a support aligned to rest on the tab.
- the correspondingly constructed connecting clamp has a complex geometry.
- the cage tension spring in particular must have a complex geometry with a large number of bends and a window recess. Furthermore, a conductor can only be inserted into the connecting terminal and clamped by the cage clamp spring when the cage clamp spring is in its release position.
- the WO 2010/022955 A1 describes an electrical connection terminal with a clamping spring, with a metal part and with a housing that accommodates the clamping spring and the metal part and has at least one conductor insertion opening.
- An actuating element mounted in the housing is provided for opening and closing the connection terminal, the actuating element having a handle via which the actuating element can be converted into an open state.
- the object underlying the present invention is to provide an improved spring-loaded connection which has a simpler structure and is easier and more flexible to handle.
- the object on which the present invention is based is achieved by a spring-loaded connection with a housing part, with a pivoting lever which can be pivoted between an open position and a closed position, with an electrically conductive connecting device which is accessible via a conductor insertion opening in the housing part, and with a contact spring, using the one via the conductor insertion opening conductor inserted into the housing part can be subjected to force on the connecting device,
- the spring-loaded connection being characterized in that the contact spring, which can be pivoted between a release position and a clamping position, has a pressure leg and a clamping leg connected to it via a flexible joint, the pivoting lever having a pusher and a Driver, wherein the pressure leg is arranged at least in the closed position of the pivot lever between the pusher and the driver, wherein by pivoting the pivot lever in its closed position, the pusher at least indirectly applies force to the pressure leg in such a way that the contact spring is pivoted into its clamping position, so that an over the conductor insertion opening
- the spring force connection according to the invention and in particular the contact spring have a simple structure. Therefore, the assembly of the spring-loaded connection is simplified. Despite the simple structure of the spring-loaded connection, a forced coupling between the position of the pivot lever and the position of the contact spring is still guaranteed.
- a movement of the pivoting lever is consequently positively coupled to a pivoting of the contact spring, with the contact spring in particular having to be transferred into its release position by means of the pivoting lever.
- the contact spring By moving the pivoting lever into its closed position, the contact spring is pivoted into its clamping position by taking the pressure leg with it, and by moving the pivoting lever into its open position, the contact spring is moved by taking the Pressure leg pivoted into its release position.
- the contact spring can be actively pivoted between the release position and the clamping position by means of the pivoting lever.
- the contact spring is therefore always subjected to force when the pivoting lever is pivoted or is always taken along by the pivoting lever.
- the spring-loaded connection according to the invention is easy to handle because the spring-loaded connection according to the invention can be operated with one hand.
- the pivoting lever is preferably pivoted into its open position, although this is not absolutely necessary, as will be explained further below. Since the pivoting lever remains in its open position, the electrical conductor can then be inserted into the spring-loaded connection via the conductor insertion opening, whereupon the pivoting lever is pivoted into its closed position. This operation can be carried out with one hand.
- the spring-loaded connection is used in particular to connect an electrical conductor to a further electrical connection device, for example with an electrical contact pin or with an electrical connection socket.
- the housing part has a conductor insertion opening for each pole, via which electrical conductors can be inserted into the housing part and brought into contact with the connecting device.
- Both the housing part and the pivoting lever are made of an electrically insulating material or include an electrically insulating material at the points where they come into contact with the electrical conductors or with the contact spring.
- the electrically insulating material is in particular a plastic.
- the contact spring which can be designed in particular as a leg spring, preferably consists of spring steel or includes it at least in the area of the flexible joint. Furthermore, the contact spring can be pivoted about a pivot axis which is defined by the housing part and/or the connecting device and/or the geometry of the contact spring.
- the pusher can also be referred to as the first driver, the first pressure element or the first pressure surface.
- the pusher is preferably designed as part of an inner surface of the pivot lever.
- the driver can also be referred to as a second driver, a second pressure edge, a return edge, a return pin or a return nose.
- the electrically conductive connection device preferably has a current bar.
- the at least indirect application of force to the pressure leg by means of the pusher or the driver of the pivoting lever is preferably carried out by means of a locking leg which is connected to the pressure leg via a locking joint.
- the pressure leg is arranged between the pusher and the driver, at least in the closed position of the pivot lever.
- the spring force connection is designed in such a way that the contact spring further has a locking leg connected to the pressure leg via a locking joint, which is arranged between the pusher and the driver, the contact spring being designed to be elastic at least in sections and an angle enclosed by the pressure leg and the locking leg being changeable, wherein when the contact spring is pivoted in the direction of its clamping position, the locking leg comes into contact with a locking device of the spring force connection, the angle between the locking leg and the pressure leg being determined by means of the
- the closing force exerted by the pivoting lever can be increased, with the locking leg engaging behind the locking device in the closed position of the pivoting lever, so that pivoting of the pivoting lever in the direction of its open position is only possible with elastic deformation of the locking joint, and when pivoting the contact spring in the direction of its release position, the driver holds the locking leg force is applied in such a way that the angle between the locking leg and the pressure leg is increased by the opening force exerted by means of the pivoting lever.
- the correspondingly designed spring force connection has the advantage that in the closed position of the pivoting element, the contact spring is locked with a latching device of the spring force connection, so that the pivoting lever can only be pivoted into its open position when a predetermined opening force is exceeded. This ensures secure contacting of the electrical conductor connected to the spring-loaded connection.
- the pusher By pivoting the pivoting lever into its closed position, the pusher applies force to the locking leg and thus the pressure leg indirectly in such a way that the contact spring is pivoted into its clamping position, so that a conductor inserted into the housing part via the conductor insertion opening is applied to the connecting device by means of the clamping leg.
- Pre-bending of the locking joint is preferably in the same direction as pre-bending of the bending joint.
- the locking joint can also be referred to as the second bending joint of the contact spring.
- the bending joint between the pressure leg and the clamping leg is then referred to as the first bending joint.
- the locking device can also be referred to as a locking lug or a locking projection.
- the latching device can be designed as part of the housing part.
- the spring force connection is designed such that the electrically conductive connecting device has a spring basket with two side walls and a busbar arranged between the side walls, an electrical conductor being positionable via the conductor insertion opening in an insertion direction between the side walls of the spring basket, with one between the side walls positioned electrical conductor can be applied to the busbar by pivoting the contact spring in its clamping position by means of the clamping leg, and wherein the locking device has at least one locking projection which is formed on an edge of a side wall facing away from the conductor insertion opening.
- the spring basket is preferably electrically connected to the busbar, which can also be referred to as a power bar. Further preferably, the spring basket and the busbar are formed in one piece. Even more preferably, the spring basket has a U-shaped cross-sectional geometry.
- the clamping leg In the clamping position of the contact spring, the clamping leg applies force to the electrical conductor on the busbar.
- the spring force connection is designed such that the contact spring has two pivot pins which extend laterally from the flexible joint in opposite directions and define a pivot axis of the contact spring, about which the contact spring can be pivoted between the release position and the clamping position.
- the spring force connection is designed such that a groove is formed in each of the two side walls of the spring basket on an edge facing the conductor insertion opening, the contact spring being suspended in the spring basket in such a way that the pivot pins are arranged in the grooves of the side walls.
- the contact spring By appropriately designing the contact spring and the spring basket, the contact spring can be hooked into the spring force connection in a particularly simple manner, so that the construction and assembly of the correspondingly designed spring force connection are particularly simple.
- the spring force connection is designed such that a pivot axis of the contact spring, about which the contact spring can be pivoted between the release position and the clamping position, is arranged between the conductor insertion opening and the pusher and/or the driver of the pivot lever.
- the spring force connection is designed such that the pusher and the driver of the pivoting lever are arranged between the conductor insertion opening and a pivoting lever axis about which the pivoting lever can be pivoted between the open position and the closed position.
- the pivot lever and the contact spring By appropriately arranging the pivot axis of the contact spring and the pivot lever pivot axis, the pivot lever and the contact spring always pivot in opposite directions. That is, if, for example, the pivot lever is pivoted clockwise from its open position to its closed position, the contact spring pivots counterclockwise from its release position to its clamping position. As a result, the correspondingly designed contact plug is very compact.
- the spring force connection is designed in such a way that the contact spring is designed to be elastic at least in sections and an angle enclosed by the pressure leg and clamping leg can be changed, so that when the contact spring is in the clamping position, a conductor can be inserted into the housing part via the conductor insertion opening and with elastic deformation of the contact spring between the clamping leg and the busbar can be positioned.
- a correspondingly designed spring-loaded connection offers the advantage that, despite the pivoting element being in the closed position and consequently the contact spring being in the clamping position, a preferably rigid conductor can still be inserted into the housing part via the conductor insertion opening and connected to the connecting device, while still ensuring that the conductor force is applied to the connecting device by means of the contact spring and is thus clamped.
- the handling of the correspondingly designed spring-loaded connection is therefore significantly improved, since the pivoting element does not necessarily have to be pivoted into its release position in order to contact an electrical conductor with the spring-loaded connection.
- the spring-loaded connection is designed such that the connecting device has a busbar with which a conductor insertion opening into the Housing part inserted conductor can be brought into contact, wherein in the clamping position of the contact spring, the clamping leg and the busbar enclose an angle of less or equal to 90 ° open to the conductor insertion opening.
- the present invention is based on the object of providing an improved circular connector which has a simple structure and is easy and flexible to handle.
- this object on which the present invention is based is achieved by a circular connector with a plurality of the spring-loaded connections described above, a housing of the circular connector forming the respective housing parts of the spring-loaded connections, and the respective conductor insertion openings of the spring-loaded connections being arranged on an end face of the housing.
- the housing preferably accommodates a number of pivoting levers, connecting devices and contact springs corresponding to the number of poles.
- the circular connector is designed in such a way that the respective spring-loaded connections are arranged relative to one another in such a way that the respective pivot levers of the spring-loaded connections are arranged angularly offset from one another on a circumference of the housing.
- FIGS 1A to 4A show a side cross-sectional view of a spring force connection 10 according to the invention in different phases of transferring a pivoting lever 20 of the spring force connection 10 from its open position to its closed position, whereby in Figure 1A the pivot lever 20 in its open position and in Figure 4A is in its closed position.
- a housing part 11 of the spring-loaded connection is not shown.
- FIGs 1B to 4B is a side cross-sectional view of a circular connector 1 according to the present invention, wherein the circular connector 1 has a plurality, in the present case five, spring-loaded connections 10.
- the respective pivot levers 20 are in the same positions as in the Figures 1A to 4A positions shown.
- FIGS 5A to 8A show a side cross-sectional view of the spring force connection 10 according to the invention in different phases of transferring the pivoting lever 20 of the spring force connection 10 from its closed position to its open position, whereby in Figure 5A the pivot lever 20 in its closed position and in Figure 8A is in its open position. Also in the Figures 5A to 8A the housing part 11 of the spring force connection 10 is not shown. In the Figures 5B to 8B is shown in a side cross-sectional view of the circular connector 1, with the respective pivot levers 20 in the same positions as in the Figures 5A to 8A positions shown.
- FIG 9 the spring force connection 10 according to the invention is shown alone in a perspective view, with both the housing part 10 and the pivot lever 20 not being shown.
- a contact spring 40 of the spring force connection 10 according to the invention is shown, wherein in Figure 10A the contact spring 40 in a side plan view and in Figure 10B is represented spatially.
- the circular connector 1 according to the invention is shown spatially in the Figures 11A and 11B shown, whereby in the illustration according to Figure 11A the respective pivot levers 20 of the respective spring force connections 10 are in their open position, whereas in Figure 11B the respective pivot levers 20 are shown in their closed position.
- the spring force connection 10 has a housing part 11, which in the illustrated embodiment is designed as a housing 11 of the circular connector 1.
- the housing 11 thus forms the in the Figures 1B to 8B and 11A and 11B shown circular connector 1, the respective housing parts 11 of the five spring-loaded connections 10.
- Each spring force connection 10 has a pivoting lever 20 which can be pivoted between an open position and a closed position.
- the pivot lever 20 In the Figures 1A and 8A the pivot lever 20 is shown in its open position, and in the Figures 4A and 5A the pivot lever 20 is shown in its closed position. In the Figures 2A , 3A , 6A and 7A the pivot lever 20 is shown in intermediate positions between the open position and the closed position.
- the spring force connection 10 also has an electrically conductive connecting device 30, which is accessible via a conductor insertion opening 13 in the housing 11.
- the Electrically conductive connecting device 30 has a spring basket 31, which in turn has two side walls 32 and a busbar 37 arranged between the side walls 32.
- An electrical conductor L is via the conductor insertion opening 13 in an in Figure 1A Insertion direction R shown can be positioned between the side walls 32 of the spring basket 31.
- the spring force connection 10 also has a contact spring 40, by means of which a conductor L inserted via the conductor insertion opening 13 into the housing 11 and between the two side walls 32 can be applied to the connecting device 30, more precisely to a busbar 37 of the connecting device 30.
- the contact spring 40 has a pressure leg 41 and a clamping leg 45 connected to it via a bending joint 44.
- the contact spring 40 also has a locking leg 43 connected to the pressure leg 41 via a locking joint 42. It can be seen that the bend of the bending joint 44 is in the same direction as the bend of the locking joint 42.
- the clamping leg 45 is curved and has a clamping edge 46 at its end.
- the contact spring 40 is between one in the Figure 1A and 8A Release position shown and one in the Figures 4A and 5A shown clamping position pivotable.
- the contact spring 40 has two pivot pins 47, which extend laterally from the flexible joint 40 in opposite directions and define a pivot axis 48 of the contact spring 40, about which the contact spring 40 can be pivoted between the release position and the clamping position.
- a groove 36 is formed in the edges 34 facing the conductor insertion opening 13.
- the contact spring 40 is suspended in the spring basket 31 in such a way that the pivot pins 47 are arranged in the grooves 36 of the side walls 32.
- the pivoting lever 20 has a pusher 21, which in the illustrated embodiment is designed as a pressure surface 21 of the pivoting lever 20.
- the pressure surface 21 or the pusher 21 are designed as an inner surface 21 of the pivot lever 20.
- the pivoting lever 20 also has a driver 22, which in the exemplary embodiment shown is designed as a curved pin 22 which is connected to the inner surface 21 to form a gap.
- the pressure leg 41 is arranged in the closed position of the pivot lever 20 between the pusher 21 and the driver 22 and thus in the space between the inner surface 21 and the driver 22. From the Figures 1A to 8A It can be seen that the locking leg 43 is arranged between the pusher 21 and the driver 22.
- the contact spring 40 is designed to be elastic and, for example, made of spring steel. Consequently, an angle between the pressure leg 41 and the clamping leg 45 can be changed. Furthermore, an angle between the pressure leg 41 and the locking leg 43 can also be changed.
- the pivoting lever 20 is pivoted into its closed position, the pusher 21 applies force to the pressure leg 41 via the locking leg 43 in such a way that the contact spring 40 is pivoted into its clamping position, so that the conductor L inserted into the housing 11 via the conductor insertion opening 13 is placed on the housing 11 by means of the clamping leg 45 Busbar 37 is subjected to force.
- the spring force connection 10 has a latching device 35, which in the illustrated embodiment is designed as two latching projections 35 of the edges 34 of the side walls 32 facing away from the conductor insertion openings 13.
- the spring force connection 10 is therefore designed in such a way that when the pivoting lever 20 is transferred from its open position to its closed position, the pressure leg 41 is subjected to force at least indirectly by means of the inner surface 21 of the pivoting lever 20.
- the pressure leg 41 is pushed through by means of the locking leg 43 the driver 22 is subjected to force. Consequently, there is a forced coupling between the position or the position of the pivot lever 20 and the position or the position of the contact spring 40.
- pivot axis 48 of the contact spring 40 is arranged between the conductor insertion opening 13 and the pusher 21 and the driver 22 of the pivot lever 20. Furthermore, it can be seen from these figures that the pusher 21 and the driver 22 of the pivoting lever 20 are arranged between the conductor insertion opening 13 and a pivoting lever axis 23 about which the pivoting lever 20 can be pivoted between its open position and its closed position.
- the contact spring 40 pivots clockwise from its release position in their clamping position.
- the clamping lever 20 is pivoted clockwise from its closed position to its open position, the clamping spring 40 pivots counterclockwise from its clamping position to its release position.
- the angle between the pressure leg 41 and the clamping leg 45 can be changed, so that when the contact spring 40 is in the clamping position, a conductor L can be inserted into the housing 11 via the conductor insertion opening 13 and with elastic deformation of the contact spring 40 between the Clamping leg 45 and the busbar 37 can be positioned.
- the contact spring is in the clamping position 40, the clamping leg 45 and the busbar 37 enclose an angle of less than 90° that is open to the conductor insertion opening 13. This makes it easier to insert the electrical conductor L into the spring-loaded connection 10.

Im Genaueren wird die der vorliegenden Erfindung zugrundeliegende Aufgabe durch einen Federkraftanschluss mit einem Gehäuseteil, mit einem Schwenkhebel, der zwischen einer Offenstellung und einer Schließstellung verschwenkbar ist, mit einer elektrisch leitfähigen Verbindungseinrichtung, die über eine Leitereinführöffnung des Gehäuseteils zugänglich ist, und mit einer Kontaktfeder, mittels der ein über die Leitereinführöffnung in das Gehäuseteil eingeführter Leiter auf die Verbindungseinrichtung kraftbeaufschlagbar ist, gelöst, wobei der Federkraftanschluss dadurch gekennzeichnet ist, dass die zwischen einer Freigabestellung und einer Klemmstellung verschwenkbare Kontaktfeder einen Druckschenkel und einen mit diesem über ein Biegegelenk verbundenen Klemmschenkel aufweist, wobei der Schwenkhebel einen Drücker und einen Mitnehmer aufweist, wobei der Druckschenkel zumindest in Schließstellung des Schwenkhebels zwischen dem Drücker und dem Mitnehmer angeordnet ist, wobei durch Verschwenken des Schwenkhebels in dessen Schließstellung der Drücker den Druckschenkel zumindest mittelbar derart kraftbeaufschlagt, dass die Kontaktfeder in deren Klemmstellung verschwenkt wird, so dass ein über die Leitereinführöffnung in das Gehäuseteil eingeführter Leiter mittels des Klemmschenkels auf die Verbindungseinrichtung kraftbeaufschlagt wird, und wobei durch Verschwenken des Schwenkhebels in dessen Offenstellung der Mitnehmer den Druckschenkel zumindest mittelbar derart kraftbeaufschlagt, dass die Kontaktfeder in deren Freigabestellung verschwenkt wird.In more detail, the object on which the present invention is based is achieved by a spring-loaded connection with a housing part, with a pivoting lever which can be pivoted between an open position and a closed position, with an electrically conductive connecting device which is accessible via a conductor insertion opening in the housing part, and with a contact spring, using the one via the conductor insertion opening conductor inserted into the housing part can be subjected to force on the connecting device, the spring-loaded connection being characterized in that the contact spring, which can be pivoted between a release position and a clamping position, has a pressure leg and a clamping leg connected to it via a flexible joint, the pivoting lever having a pusher and a Driver, wherein the pressure leg is arranged at least in the closed position of the pivot lever between the pusher and the driver, wherein by pivoting the pivot lever in its closed position, the pusher at least indirectly applies force to the pressure leg in such a way that the contact spring is pivoted into its clamping position, so that an over the conductor insertion opening of conductors inserted into the housing part is applied to the connecting device by means of the clamping leg, and by pivoting the pivoting lever into its open position, the driver at least indirectly applies force to the pressure leg in such a way that the contact spring is pivoted into its release position.
Der erfindungsgemäße Federkraftanschluss und insbesondere die Kontaktfeder weisen einen einfachen Aufbau auf. Daher ist der Zusammenbau des Federkraftanschlusses vereinfacht ermöglicht. Trotz des einfachen Aufbaus des Federkraftanschlusses ist weiterhin eine Zwangskopplung zwischen der Stellung des Schwenkhebels und der Stellung der Kontaktfeder gewährleistet.The spring force connection according to the invention and in particular the contact spring have a simple structure. Therefore, the assembly of the spring-loaded connection is simplified. Despite the simple structure of the spring-loaded connection, a forced coupling between the position of the pivot lever and the position of the contact spring is still guaranteed.
Eine Bewegung des Schwenkhebels ist folglich mit einer Verschwenkung der Kontaktfeder zwangsgekoppelt, wobei insbesondere die Überführung der Kontaktfeder in deren Freigabestellung mittels des Schwenkhebels erfolgen muss. Durch Überführen des Schwenkhebels in dessen Schließstellung wird die Kontaktfeder durch Mitnahme des Druckschenkels in deren Klemmstellung verschwenkt, und durch Überführen des Schwenkhebels in dessen Offenstellung wird die Kontaktfeder durch Mitnahme des Druckschenkels in deren Freigabestellung verschwenkt. Mit anderen Worten ist die Kontaktfeder mittels des Schwenkhebels zwischen der Freigabestellung und der Klemmstellung aktiv verschwenkbar. Die Kontaktfeder wird folglich bei einer Verschwenkung des Schwenkhebels stets kraftbeaufschlagt bzw. von dem Schwenkhebel stets mitgenommen.A movement of the pivoting lever is consequently positively coupled to a pivoting of the contact spring, with the contact spring in particular having to be transferred into its release position by means of the pivoting lever. By moving the pivoting lever into its closed position, the contact spring is pivoted into its clamping position by taking the pressure leg with it, and by moving the pivoting lever into its open position, the contact spring is moved by taking the Pressure leg pivoted into its release position. In other words, the contact spring can be actively pivoted between the release position and the clamping position by means of the pivoting lever. The contact spring is therefore always subjected to force when the pivoting lever is pivoted or is always taken along by the pivoting lever.
Darüber hinaus weist der erfindungsgemäße Federkraftanschluss eine einfache Handhabung auf, denn der erfindungsgemäße Federkraftanschluss ist einhändig zu bedienen. Zum Verbinden eines elektrischen Leiters mit dem Federkraftanschluss wird vorzugsweise der Schwenkhebel in dessen Offenstellung verschwenkt, wobei dies nicht unbedingt notwendig ist, wie weiter unten noch erläutert wird. Da der Schwenkhebel in dessen Offenstellung verbleibt, kann anschließend der elektrische Leiter über die Leitereinführöffnung in den Federkraftanschluss eingeführt werden, woraufhin der Schwenkhebel in dessen Schließstellung verschwenkt wird. Diese Betätigung ist einhändig durchführbar.In addition, the spring-loaded connection according to the invention is easy to handle because the spring-loaded connection according to the invention can be operated with one hand. To connect an electrical conductor to the spring-loaded connection, the pivoting lever is preferably pivoted into its open position, although this is not absolutely necessary, as will be explained further below. Since the pivoting lever remains in its open position, the electrical conductor can then be inserted into the spring-loaded connection via the conductor insertion opening, whereupon the pivoting lever is pivoted into its closed position. This operation can be carried out with one hand.
Der Federkraftanschluss dient insbesondere zum Verbinden eines elektrischen Leiters mit einer weiteren elektrischen Verbindungseinrichtung, z.B. mit einem elektrischen Kontaktstift oder mit einer elektrischen Verbindungsbuchse. Das Gehäuseteil weist in diesem Fall für jeden Pol jeweils eine Leitereinführöffnung auf, über die elektrische Leiter in das Gehäuseteil einführbar und jeweils mit der Verbindungseinrichtung in Kontakt bringbar sind.The spring-loaded connection is used in particular to connect an electrical conductor to a further electrical connection device, for example with an electrical contact pin or with an electrical connection socket. In this case, the housing part has a conductor insertion opening for each pole, via which electrical conductors can be inserted into the housing part and brought into contact with the connecting device.
Sowohl das Gehäuseteil als auch der Schwenkhebel sind aus einem elektrisch isolierenden Material gebildet oder umfassen ein elektrisch isolierendes Material an den Stellen, an denen diese mit den elektrischen Leitern bzw. mit der Kontaktfeder in Kontakt kommen. Bei dem elektrisch isolierenden Material handelt es sich insbesondere um einen Kunststoff.Both the housing part and the pivoting lever are made of an electrically insulating material or include an electrically insulating material at the points where they come into contact with the electrical conductors or with the contact spring. The electrically insulating material is in particular a plastic.
Die Kontaktfeder, die insbesondere als Schenkelfeder ausgebildet sein kann, besteht vorzugsweise aus einem Federstahl oder umfasst diesen zumindest im Bereich des Biegegelenks. Ferner ist die Kontaktfeder um eine Schwenkachse verschwenkbar, die durch das Gehäuseteil und/oder die Verbindungseinrichtung und/oder die Geometrie der Kontaktfeder definiert ist.The contact spring, which can be designed in particular as a leg spring, preferably consists of spring steel or includes it at least in the area of the flexible joint. Furthermore, the contact spring can be pivoted about a pivot axis which is defined by the housing part and/or the connecting device and/or the geometry of the contact spring.
Der Drücker kann auch als erster Mitnehmer, als erstes Druckelement oder als erste Druckfläche bezeichnet werden. Der Drücker ist vorzugsweise als Teil einer Innenfläche des Schwenkhebels ausgebildet. Der Mitnehmer kann auch als zweiter Mitnehmer, als zweite Druckkante, als Rückholkante, als Rückholstift oder als Rückholnase bezeichnet werden.The pusher can also be referred to as the first driver, the first pressure element or the first pressure surface. The pusher is preferably designed as part of an inner surface of the pivot lever. The driver can also be referred to as a second driver, a second pressure edge, a return edge, a return pin or a return nose.
Die elektrisch leitfähige Verbindungseinrichtung weist vorzugsweise einen Strombalken auf.The electrically conductive connection device preferably has a current bar.
Die zumindest mittelbare Kraftbeaufschlagung des Druckschenkels mittels des Drücker bzw. des Mitnehmers des Schwenkhebels erfolgt vorzugsweise mittels eines Rastschenkels, der mit dem Druckschenkel über ein Rastgelenk verbunden ist.The at least indirect application of force to the pressure leg by means of the pusher or the driver of the pivoting lever is preferably carried out by means of a locking leg which is connected to the pressure leg via a locking joint.
Der Druckschenkel ist zumindest in Schließstellung des Schwenkhebels zwischen dem Drücker und dem Mitnehmer angeordnet.The pressure leg is arranged between the pusher and the driver, at least in the closed position of the pivot lever.
Der Federkraftanschluss ist derart ausgebildet, dass die Kontaktfeder ferner einen über ein Rastgelenk mit dem Druckschenkel verbundenen Rastschenkel aufweist, der zwischen dem Drücker und dem Mitnehmer angeordnet ist, wobei die Kontaktfeder zumindest abschnittsweise elastisch ausgebildet ist und ein vom Druckschenkel und Rastschenkel eingeschlossener Winkel veränderbar ist, wobei bei Verschwenken der Kontaktfeder in Richtung deren Klemmstellung der Rastschenkel mit einer Rasteinrichtung des Federkraftanschlusses in Kontakt kommt, wobei der Winkel zwischen dem Rastschenkel und dem Druckschenkel durch mittels des Schwenkhebels ausgeübter Schließkraft vergrößerbar ist, wobei in Schließstellung des Schwenkhebels der Rastschenkel die Rasteinrichtung hintergreift, so dass ein Verschwenken des Schwenkhebels in Richtung dessen Offenstellung nur unter elastischer Verformung des Rastgelenks ermöglicht ist, und wobei bei Verschwenken der Kontaktfeder in Richtung deren Freigabestellung der Mitnehmer den Rastschenkel derart kraftbeaufschlagt, dass der Winkel zwischen dem Rastschenkel und dem Druckschenkel durch mittels des Schwenkhebels ausgeübter Öffnungskraft vergrößert wird.The spring force connection is designed in such a way that the contact spring further has a locking leg connected to the pressure leg via a locking joint, which is arranged between the pusher and the driver, the contact spring being designed to be elastic at least in sections and an angle enclosed by the pressure leg and the locking leg being changeable, wherein when the contact spring is pivoted in the direction of its clamping position, the locking leg comes into contact with a locking device of the spring force connection, the angle between the locking leg and the pressure leg being determined by means of the The closing force exerted by the pivoting lever can be increased, with the locking leg engaging behind the locking device in the closed position of the pivoting lever, so that pivoting of the pivoting lever in the direction of its open position is only possible with elastic deformation of the locking joint, and when pivoting the contact spring in the direction of its release position, the driver holds the locking leg force is applied in such a way that the angle between the locking leg and the pressure leg is increased by the opening force exerted by means of the pivoting lever.
Der entsprechend ausgebildete Federkraftanschluss weist den Vorteil auf, dass in Schließstellung des Schwenkelements eine Verrastung der Kontaktfeder mit einer Rasteinrichtung des Federkraftanschlusses erfolgt, so dass der Schwenkhebel nur bei Übersteigen einer vorgegebenen Öffnungskraft in dessen Offenstellung verschwenkt werden kann. Somit ist eine sichere Kontaktierung des mit dem Federkraftanschluss verbundenen elektrischen Leiters gewährleistet.The correspondingly designed spring force connection has the advantage that in the closed position of the pivoting element, the contact spring is locked with a latching device of the spring force connection, so that the pivoting lever can only be pivoted into its open position when a predetermined opening force is exceeded. This ensures secure contacting of the electrical conductor connected to the spring-loaded connection.
Durch Verschwenken des Schwenkhebels in dessen Schließstellung kraftbeaufschlagt der Drücker den Rastschenkel und somit den Druckschenkel mittelbar derart, dass die Kontaktfeder in deren Klemmstellung verschwenkt wird, so dass ein über die Leitereinführöffnung in das Gehäuseteil eingeführter Leiter mittels des Klemmschenkels auf die Verbindungseinrichtung kraftbeaufschlagt wird.By pivoting the pivoting lever into its closed position, the pusher applies force to the locking leg and thus the pressure leg indirectly in such a way that the contact spring is pivoted into its clamping position, so that a conductor inserted into the housing part via the conductor insertion opening is applied to the connecting device by means of the clamping leg.
Durch Verschwenken des Schwenkelements in dessen Offenstellung kraftbeaufschlagt der Mitnehmer den Rastschenkel und somit den Druckschenkel mittelbar derart, dass die Kontaktfeder in deren Freigabestellung verschwenkt wird.By pivoting the pivoting element into its open position, the driver applies force to the locking leg and thus the pressure leg indirectly in such a way that the contact spring is pivoted into its release position.
Durch die Vergrößerung des Winkels zwischen dem Rastschenkel und dem Druckschenkel hintergreift der Rastschenkel nicht mehr die Rasteinrichtung, so dass ein Verschwenken der Kontaktfeder in deren Freigabestellung durch Verschwenken des Schwenkhebels in dessen Offenstellung annähernd widerstandslos möglich ist.By increasing the angle between the locking leg and the pressure leg, the locking leg no longer engages behind the Locking device, so that the contact spring can be pivoted into its release position by pivoting the pivoting lever into its open position with almost no resistance.
Eine Vorbiegung des Rastgelenks ist vorzugsweise gleichsinnig wie eine Vorbiegung des Biegegelenks.Pre-bending of the locking joint is preferably in the same direction as pre-bending of the bending joint.
Das Rastgelenk kann auch als zweites Biegegelenk der Kontaktfeder bezeichnet werden. Das Biegegelenk zwischen dem Druckschenkel und dem Klemmschenkel wird dann als erstes Biegegelenk bezeichnet.The locking joint can also be referred to as the second bending joint of the contact spring. The bending joint between the pressure leg and the clamping leg is then referred to as the first bending joint.
Die Rasteinrichtung kann auch als Rastnase oder als Rastvorsprung bezeichnet werden. Die Rasteinrichtung kann als Teil des Gehäuseteils ausgebildet sein.The locking device can also be referred to as a locking lug or a locking projection. The latching device can be designed as part of the housing part.
Weiter vorzugsweise ist der Federkraftanschluss derart ausgebildet, dass die elektrisch leitfähige Verbindungseinrichtung einen Federkorb mit zwei Seitenwänden und einer zwischen den Seitenwänden angeordneten Stromschiene aufweist, wobei ein elektrischer Leiter über die Leitereinführöffnung in einer Einführrichtung zwischen die Seitenwände des Federkorbes positionierbar ist, wobei ein zwischen den Seitenwänden positionierter elektrischer Leiter durch Verschwenken der Kontaktfeder in deren Klemmstellung mittels des Klemmschenkels auf die Stromschiene kraftbeaufschlagbar ist, und wobei die Rasteinrichtung zumindest einen Rastvorsprung aufweist, der an einer der Leitereinführöffnung abgewandten Kante einer Seitenwand ausgebildet ist.Further preferably, the spring force connection is designed such that the electrically conductive connecting device has a spring basket with two side walls and a busbar arranged between the side walls, an electrical conductor being positionable via the conductor insertion opening in an insertion direction between the side walls of the spring basket, with one between the side walls positioned electrical conductor can be applied to the busbar by pivoting the contact spring in its clamping position by means of the clamping leg, and wherein the locking device has at least one locking projection which is formed on an edge of a side wall facing away from the conductor insertion opening.
Der Federkorb ist vorzugsweise mit der Stromschiene, die auch als Strombalken bezeichnet werden kann, elektrisch verbunden. Weiter vorzugsweise sind der Federkorb und die Stromschiene einstückig ausgebildet. Nochmals weiter vorzugsweise weist der Federkorb eine U-förmige Querschnittsgeometrie auf.The spring basket is preferably electrically connected to the busbar, which can also be referred to as a power bar. Further preferably, the spring basket and the busbar are formed in one piece. Even more preferably, the spring basket has a U-shaped cross-sectional geometry.
In der Klemmstellung der Kontaktfeder kraftbeaufschlagt der Klemmschenkel den elektrischen Leiter auf die Stromschiene.In the clamping position of the contact spring, the clamping leg applies force to the electrical conductor on the busbar.
Vorzugsweise ist der Federkraftanschluss derart ausgebildet, dass die Kontaktfeder zwei Schwenkzapfen aufweist, die sich seitlich aus dem Biegegelenk in entgegengesetzte Richtungen erstrecken und eine Schwenkachse der Kontaktfeder definieren, um die die Kontaktfeder zwischen der Freigabestellung und der Klemmstellung schwenkbar ist.Preferably, the spring force connection is designed such that the contact spring has two pivot pins which extend laterally from the flexible joint in opposite directions and define a pivot axis of the contact spring, about which the contact spring can be pivoted between the release position and the clamping position.
Weiter vorzugsweise ist der Federkraftanschluss derart ausgebildet, dass in jeder der zwei Seitenwände des Federkorbes jeweils eine Nut an einer der Leitereinführöffnung zugewandten Kante ausgebildet ist, wobei die Kontaktfeder derart in dem Federkorb eingehängt ist, dass die Schwenkzapfen in den Nuten der Seitenwände angeordnet sind.Further preferably, the spring force connection is designed such that a groove is formed in each of the two side walls of the spring basket on an edge facing the conductor insertion opening, the contact spring being suspended in the spring basket in such a way that the pivot pins are arranged in the grooves of the side walls.
Durch eine entsprechende Ausbildung der Kontaktfeder und des Federkorbes kann die Kontaktfeder auf besonders einfache Art und Weise in den Federkraftanschluss eingehängt werden, so dass der Aufbau und die Montage des entsprechend ausgebildeten Federkraftanschlusses besonders einfach sind.By appropriately designing the contact spring and the spring basket, the contact spring can be hooked into the spring force connection in a particularly simple manner, so that the construction and assembly of the correspondingly designed spring force connection are particularly simple.
Vorzugsweise ist der Federkraftanschluss derart ausgebildet, dass eine Schwenkachse der Kontaktfeder, um die die Kontaktfeder zwischen der Freigabestellung und der Klemmstellung schwenkbar ist, zwischen der Leitereinführöffnung und dem Drücker und/oder dem Mitnehmer des Schwenkhebels angeordnet ist.Preferably, the spring force connection is designed such that a pivot axis of the contact spring, about which the contact spring can be pivoted between the release position and the clamping position, is arranged between the conductor insertion opening and the pusher and/or the driver of the pivot lever.
Weiter vorzugsweise ist der Federkraftanschluss derart ausgebildet, dass der Drücker und der Mitnehmer des Schwenkhebels zwischen der Leitereinführöffnung und einer Schwenkhebelachse, um die der Schwenkhebel zwischen der Offenstellung und der Schließstellung schwenkbar ist, angeordnet sind.Further preferably, the spring force connection is designed such that the pusher and the driver of the pivoting lever are arranged between the conductor insertion opening and a pivoting lever axis about which the pivoting lever can be pivoted between the open position and the closed position.
Durch eine entsprechende Anordnung der Schwenkachse der Kontaktfeder und der Schwenkhebelschwenkachse schwenken der Schwenkhebel und die Kontaktfeder stets in entgegengesetzte Richtungen. D.h., wenn beispielsweise der Schwenkhebel im Uhrzeigersinn von seiner Offenstellung in seine Schließstellung verschwenkt wird, verschwenkt die Kontaktfeder entgegengesetzt zum Uhrzeigersinn von deren Freigabestellung in deren Klemmstellung. Dadurch baut der entsprechend ausgebildete Kontaktstecker sehr kompakt.By appropriately arranging the pivot axis of the contact spring and the pivot lever pivot axis, the pivot lever and the contact spring always pivot in opposite directions. That is, if, for example, the pivot lever is pivoted clockwise from its open position to its closed position, the contact spring pivots counterclockwise from its release position to its clamping position. As a result, the correspondingly designed contact plug is very compact.
Der Federkraftanschluss ist derart ausgebildet, dass die Kontaktfeder zumindest abschnittsweise elastisch ausgebildet ist und ein vom Druckschenkel und Klemmschenkel eingeschlossener Winkel veränderbar ist, so dass bei in Klemmstellung befindlicher Kontaktfeder ein Leiter über die Leitereinführöffnung in das Gehäuseteil einführbar und unter elastischer Verformung der Kontaktfeder zwischen dem Klemmschenkel und der Stromschiene positionierbar ist.The spring force connection is designed in such a way that the contact spring is designed to be elastic at least in sections and an angle enclosed by the pressure leg and clamping leg can be changed, so that when the contact spring is in the clamping position, a conductor can be inserted into the housing part via the conductor insertion opening and with elastic deformation of the contact spring between the clamping leg and the busbar can be positioned.
Ein entsprechend ausgebildeter Federkraftanschluss bietet den Vorteil, dass trotz in Schließstellung befindlichem Schwenkelement und folglich in Klemmstellung befindlicher Kontaktfeder weiterhin ein vorzugsweise starrer Leiter über die Leitereinführöffnung in das Gehäuseteil eingeführt und mit der Verbindungseinrichtung in Verbindung gebracht werden kann, wobei weiterhin gewährleistet bleibt, dass der Leiter mittels der Kontaktfeder auf die Verbindungseinrichtung kraftbeaufschlagt und somit geklemmt ist. Die Handhabbarkeit des entsprechend ausgebildeten Federkraftanschlusses ist daher erheblich verbessert, da zum Kontaktieren eines elektrischen Leiters mit dem Federkraftanschluss das Schwenkelement nicht notwendigerweise in dessen Freigabestellung verschwenkt werden muss.A correspondingly designed spring-loaded connection offers the advantage that, despite the pivoting element being in the closed position and consequently the contact spring being in the clamping position, a preferably rigid conductor can still be inserted into the housing part via the conductor insertion opening and connected to the connecting device, while still ensuring that the conductor force is applied to the connecting device by means of the contact spring and is thus clamped. The handling of the correspondingly designed spring-loaded connection is therefore significantly improved, since the pivoting element does not necessarily have to be pivoted into its release position in order to contact an electrical conductor with the spring-loaded connection.
Weiter vorzugsweise ist der Federkraftanschluss derart ausgebildet, dass die Verbindungseinrichtung eine Stromschiene aufweist, mit der ein über die Leitereinführöffnung in das Gehäuseteil eingeführter Leiter in Kontakt bringbar ist, wobei in Klemmstellung der Kontaktfeder der Klemmschenkel und die Stromschiene einen zur Leitereinführöffnung geöffneten Winkel von weniger oder gleich 90° einschließen.Further preferably, the spring-loaded connection is designed such that the connecting device has a busbar with which a conductor insertion opening into the Housing part inserted conductor can be brought into contact, wherein in the clamping position of the contact spring, the clamping leg and the busbar enclose an angle of less or equal to 90 ° open to the conductor insertion opening.
Durch eine entsprechende Ausbildung des Federkraftanschlusses und insbesondere der Kontaktfeder ist ein nochmals vereinfachtes Einführen eines Leiters trotz sich in Schließstellung befindlichen Schwenkelements ermöglicht. Weiterhin wird durch eine entsprechende Winkelstellung des Klemmschenkels hin zum in der Verbindungseinrichtung eingeführten Leiter gewährleistet, dass der Klemmschenkel der Kontaktfeder einem ungewollten Herausziehen des Leiters verbessert entgegenwirkt, da sich die Kante des Klemmschenkels der Kontaktfeder bei einem Herausziehen des Leiters aus dem Gehäuseteil in den Leiter eingräbt.By appropriately designing the spring-loaded connection and in particular the contact spring, a further simplified insertion of a conductor is made possible despite the pivoting element being in the closed position. Furthermore, a corresponding angular position of the clamping leg towards the conductor inserted in the connecting device ensures that the clamping leg of the contact spring better counteracts unwanted pulling out of the conductor, since the edge of the clamping leg of the contact spring digs into the conductor when the conductor is pulled out of the housing part .
Ferner liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen verbesserten Rundsteckverbinder bereitzustellen, der einen einfachen Aufbau und eine einfache und flexible Handhabbarkeit aufweist.Furthermore, the present invention is based on the object of providing an improved circular connector which has a simple structure and is easy and flexible to handle.
Diese Aufgabe wird durch einen Rundsteckverbinder mit den Merkmalen von Anspruch 10 gelöst.This task is solved by a circular connector with the features of
Im Genaueren wird diese der vorliegenden Erfindung zugrundeliegende Aufgabe durch einen Rundsteckverbinder mit einer Vielzahl von den oben beschriebenen Federkraftanschlüssen gelöst, wobei ein Gehäuse des Rundsteckverbinders die jeweiligen Gehäuseteile der Federkraftanschlüsse bildet, und wobei die jeweiligen Leitereinführöffnungen der Federkraftanschlüsse an einer Stirnseite des Gehäuses angeordnet sind.In more detail, this object on which the present invention is based is achieved by a circular connector with a plurality of the spring-loaded connections described above, a housing of the circular connector forming the respective housing parts of the spring-loaded connections, and the respective conductor insertion openings of the spring-loaded connections being arranged on an end face of the housing.
Das Gehäuse nimmt vorzugsweise eine der Polzahl entsprechende Anzahl von Schwenkhebeln, Verbindungseinrichtungen und Kontaktfedern auf.The housing preferably accommodates a number of pivoting levers, connecting devices and contact springs corresponding to the number of poles.
Vorzugsweise ist der Rundsteckverbinder derart ausgebildet, dass die jeweiligen Federkraftanschlüsse derart zueinander angeordnet sind, dass die jeweiligen Schwenkhebel der Federkraftanschlüsse an einem Umfang des Gehäuses winkelversetzt zueinander angeordnet sind.Preferably, the circular connector is designed in such a way that the respective spring-loaded connections are arranged relative to one another in such a way that the respective pivot levers of the spring-loaded connections are arranged angularly offset from one another on a circumference of the housing.
Durch eine entsprechende Ausbildung des Rundsteckverbinders baut diese besonders kompakt. Ferner ist die Bedienbarkeit der Schwenkhebel bei einer entsprechenden Anordnung vereinfacht möglich.Appropriate design of the circular connector makes it particularly compact. Furthermore, the operability of the pivoting levers is simplified with an appropriate arrangement.
