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.
