Definitions

  • the invention relates to a conductor connection clamp for connecting electrical conductors to a conductor rail.
  • the conductor terminal has an insulating housing with a housing base and a housing cover that can be connected to the housing base.
  • the housing base has a conductor insertion opening which opens into a conductor connection space in the housing base. At least two clamping points are formed in the conductor connection space, at which electrical conductors inserted into the conductor insertion opening can be clamped to the busbar.
  • connection spring element for clamping a conductor to a current bar.
  • the connection spring element has two clamping springs, so it is designed as a double spring.
  • the connecting spring element has an intermediate wall leg, which is a material tab bent out of the connecting spring element and forms a partition between the two clamping springs.
  • the U.S. 2014/127932 A1 shows a connection terminal with a housing in whose conductor connection space a spring seat is arranged separately, which at the same time forms the partition for two clamping springs arranged next to one another on the spring seat.
  • the housing can optionally be closed with a housing cover.
  • the U.S. 2008/248699 A1 describes a terminal with an actuator that is inserted into an opening of the housing and conductor entry openings having. By depressing the actuating element, two opposite clamping points are opened.
  • the actuator includes an integral divider for the two ports and a back wall separating the dual port from another dual port.
  • the U.S. 2018/277968 A1 discloses a connection device for electrical conductors with a housing, the housing having free spaces into which a spring carrier can be inserted.
  • the spring carrier can be equipped with clamping springs and clamping cages that form clamping points for electrical conductors to be clamped.
  • the terminal cages are placed on a busbar.
  • the ladder clamp according to claim 1 the projection formed on the housing cover, which protrudes into the conductor connection space when the housing cover is connected to the housing body, forms a partition between two clamping points.
  • the formed partition ensures a defined and reliable guidance of the conductors to be connected. The improved guidance is also ensured when conductors are inserted at greater angles and not parallel to the walls of conductor entry openings.
  • the projection forms a partition between the two clamping points, so that the clamping points are separated from one another in the manner of a chamber.
  • a chamber is understood to mean a partitioned area that does not have to be completely closed off.
  • an improved chamber separation is carried out according to the invention. while at the DE 10 2015 105 757 A1 a chamber separation is produced by means of a partition wall of the contact part, ie material with good electrical conductivity, the chamber separation according to the invention takes place with the insulating material of the housing cover in cooperation with the insulating material housing.
  • a terminal point is understood to mean an area of electrical contact between a connection element, for example a busbar, and an electrical conductor.
  • a conductor rail also known as a current bar, is a largely rigid electrical conductor, for example a metal strip.
  • An insulating housing is a housing made of an insulating, electrically non-conductive material, such as plastic.
  • the housing base body of the insulating housing is a carrier for components of the conductor connection terminal, for example for the busbar and other connection or contact elements.
  • the housing body has a conductor insertion opening, which can also be designed as an elongate conductor entry channel, as a result of which the housing body provides a guide for inserted conductors.
  • the conductor entry channel leads one or more electrical conductors to their respective terminal points at which the conductors can be clamped to the busbar.
  • the basic body of the housing has a conductor connection space which adjoins the conductor entry opening.
  • a conductor connection space is, for example, a cavity in which the terminal points are formed.
  • a busbar and the stripped ends of inserted conductors that make electrical contact with the busbar are located in the conductor connection space.
  • the housing body can more Have openings, for example, for actuating tools for actuating, for example opening a terminal point, or for test tools, for example to check the electrical potential present at a terminal point.
  • the housing cover forms a closure of the housing body.
  • the insulating material housing can also have other components and can therefore be designed in several parts with more than two parts.
  • the housing cover can preferably be releasably connected to the housing base body. In this way, even after the housing cover has been attached to the housing body, it is possible to check or maintain the conductor connection terminal located in the insulating housing.
  • plug-in, screw or snap-in connections can be considered as detachable connections.
  • a projection formed onto the housing cover is understood to mean a form of any shape protruding from the housing cover, which is suitable for forming a partition wall between two clamping points.
  • the projection can be round, bar-like or L-shaped, for example.
  • the L-legs can be designed differently.
  • one leg can be round and rod-shaped and the other leg can be flat and, for example, approximately cuboid.
  • the legs of such an L-shape can be made in one piece, but also in multiple pieces and made of different materials.
  • the projection protrudes into the conductor connection space and forms a partition wall between two terminal points.
  • the projection does not necessarily have to extend only in one direction or in one plane, but can run in different, in particular several, directions and angles.
  • the projection can extend partially or entirely parallel to inserted conductors.
  • the projection may extend partially or entirely across inserted conductors.
  • the conductor terminal for example, multiple conductor entry openings, multiple projections and have multiple partitions.
  • the conductor connection terminal can also have more than two clamping points.
  • the projection of the conductor terminal can be made of an insulating material, ie not electrically conductive.
  • the non-electrically conductive separation of the terminal points enables a defined current transfer exclusively at the terminal points.
  • the projection can be formed in one piece with the housing cover.
  • a one-piece design of the projection with the housing cover simplifies the production of the housing cover, which can be done, for example, using an injection molding process. If the projection is designed in one piece with the housing cover, no additional connecting means are required to connect the projection to the housing cover. In principle, however, it is also conceivable to connect a separately designed projection to the housing cover, for example by gluing. As a result, conductor connection terminals can also be retrofitted with a projection and thus retrofitted.
  • the conductor connection terminal can have a clamping spring to form clamping points in the conductor connection space.
  • a clamping spring consists of a contact leg and a clamping leg. Together with the conductor rail, the clamping leg forms a clamping point in which an electrical conductor is clamped with spring force.
  • a particularly reliable, proven and cost-effective formation of a clamping point is possible with a clamping spring.
  • the clamping spring can be part of a contact element, which is designed, for example, as a sheet metal part with a clamping spring arranged on it or formed in one piece.
  • An opening can be provided in the contact element, for example in the sheet metal part, for receiving or guiding an electrical conductor inserted into the conductor insertion opening.
  • other means of forming a terminal point are also conceivable, for example screw connections, insulation displacement connections or the like.
  • the insulating housing can have a spring carrier as a support for one or more clamping springs.
  • the spring carrier carries or supports the entire clamping spring or individual legs, for example the clamping leg of the spring.
  • the spring carrier can be provided as a separate insert that is inserted into the insulating housing and optionally fixed. It is preferred if the spring carrier is formed in one piece with the housing base body, as a result of which the manufacturing and assembly costs are significantly reduced. It is also conceivable that a part of the spring carrier, for example one half, is integrally formed on the housing base body and another part of the spring carrier, for example the other half, is integrally formed on the housing cover. This achieves increased rigidity of the spring support, so that improved support is made possible, since possible deformation or yielding of the spring support when a clamping leg of the clamping spring is deflected is minimized.
  • the conductor connection terminal can be designed as a double connection for two electrical conductors.
  • the conductor connection terminal can have common or separate conductor entry openings for the two conductors.
  • the two conductors can be provided for connection to a common electrical potential or to different electrical potentials.
  • a projection made of an insulating material molded onto the housing cover is particularly advantageous since it prevents current transfer between the conductors or between their terminal points. Double connections are preferred when space is limited.
  • the dividing wall formed by the projection formed on the housing cover enables a particularly space-saving and space-optimized design of the double connection.
  • a common actuating device for at least two clamping points can be provided in the housing base body. This greatly simplifies handling when connecting electrical conductors.
  • the actuating device can be, for example, an opening for an actuating tool or an actuating mechanism, for example a pusher.
  • the actuating device is used to actuate a clamping point, for example to open or close the clamping point.
  • the clamping spring can be shifted to open or close the clamping point.
  • the Actuating device can be designed to interact with two clamping legs of the clamping spring arranged next to one another.
  • the projection can have an arcuate shoulder, which merges into a partition wall protruding from the shoulder towards the conductor connection space.
  • a support or a guide for a clamping spring is additionally provided by the arcuate shoulder.
  • One leg, in particular a clamping leg, of the clamping spring can rest on the arcuate shoulder and be laterally delimited and guided by the partition wall projecting perpendicularly from the shoulder.
  • the dividing wall protruding from the shoulder can, in particular, protrude perpendicularly from the shoulder.
  • the arcuate shoulder can transition towards the housing cover into a wall protruding from the shoulder.
  • the housing cover is not to be equated with the wall. Rather, a separate material tab is formed on the projection or adjoining the projection on the housing cover.
  • the wall protruding from the shoulder can, in particular, protrude perpendicularly from the shoulder.
  • Such a wall enables improved guidance of a clamping spring held by the arcuate shoulder.
  • Such a wall can serve as a spacer between the clamping spring and the housing cover.
  • Such a wall can also serve as an overload stop for a clamping spring that is deflected, for example, to open the clamping point.
  • the projection can have a connecting device for connecting the housing base body to the housing cover.
  • the connecting device can be, for example, an opening for a screw.
  • the connecting device is preferably a blind hole as an insertion opening that can interact with a pin on the housing base body, or a pin that can interact with a blind hole as an insertion opening on the housing base body.
  • the connecting device can also be a latching device, for example a latching lug that can interact with a latching opening in the housing base body, or a latching opening that can interact with a latching lug formed on the housing base body.
  • the connecting device on the projection is offset further inwards compared to a connecting device on the housing edge of the insulating material housing. This enables the housing base body to be held better on the housing cover and protects the connection point from external influences, for example from dirt. At this position, the connection point does not interfere with the insertion of conductors into the conductor connection space.
  • the dividing wall formed by the projection can have a rounded and/or tapering edge in the direction of the conductor insertion opening.
  • the curves of the partition are on the side of the partition facing the conductor insertion opening.
  • Tapering is understood to mean a decreasing diameter of the partition wall in the direction of the conductor insertion opening, that is to say the partition wall becomes narrower in the direction of the conductor insertion opening.
  • the guidance of inserted conductors is thus improved.
  • the ends of the conductors are prevented from kinking or fanning out as a result of individual wires slipping off a sharp or wide edge of the partition. In this way, an electrical conductor that is inserted at an angle or at an angle is guided back in the direction of its terminal point.
  • the basic housing body can have a defined contour that deviates from a purely rectangular shape, and the housing cover can have a section with a negative contour to the contour.
  • the contour and the negative form of the contour can be designed, for example, as an arc, zigzag or wavy contour. This simplifies the assembly of the housing cover on the housing base body, since the housing cover can only be fitted in a specific orientation. This ensures that the projection and the partition wall formed with it are automatically located in the intended position in the conductor connection space during assembly.
  • the housing body and the housing cover can have positioning elements to facilitate assembly.
  • the positioning elements can be designed, for example, as elevations and depressions according to a positive locking pin-hole principle. They can also form a latching connection when they are plugged into one another, in that a slight undercut is provided for both positioning elements.
  • the housing cover forms a side wall of the insulating housing when the housing cover is placed on the housing body. When the housing body and housing cover are assembled, the housing cover forms a lateral closure of the conductor connection space.
  • a lateral termination or a side wall is understood to mean an area of the insulating material housing which runs essentially parallel to the conductor insertion direction. In principle, all four side walls of the insulating material housing running parallel to the conductor insertion direction can be considered for forming the projection.
  • the assembly or connection direction of the housing cover with the housing body is transverse to the conductor insertion direction.
  • the housing cover can be a substantially flat part of the insulating housing, in which the projection represents the only significant elevation from the plane of the housing cover. By molding the projection onto a housing cover designed as a side wall, the projection can have a comparatively small extent in order to achieve the desired position in the conductor connection space between two terminal points.
  • the Figures 1 to 7 show a conductor terminal 1 according to the invention or individual components of the conductor terminal 1.
  • This has an insulating material housing with a housing base body 4a and a lateral housing cover 4b.
  • the housing base body 4a has two conductor insertion openings 9, into which two conductors 2 are inserted and which each form a clamping point 6 with a busbar 3 and a clamping spring 10 in a conductor connection space 5.
  • the conductor entry openings 9 are designed as elongated conductor entry channels. As in figure 1 As can be seen, the conductors are not straight but inserted into the conductor insertion openings 9 at different angles.
  • a partition 8 is provided between the terminal points 6.
  • the partition wall 8 is formed by a projection 7 formed onto the housing cover 4b.
  • the projection 7 has an L-shape when viewed from the side, with a round web which connects the flat, plate-shaped partition 8 of the projection 7 to the housing cover 4b.
  • the partition wall 8 has a rounded edge 11 that tapers in the direction of the conductor insertion openings 9 in order to prevent conductors 2 from fanning out on the partition wall 8 . In this way, an electrical conductor 2 that is inserted at an angle is guided back in the direction of its terminal point 6 .
  • a connecting device here in the form of a lower blind hole 16g, with which the housing cover 4b can be connected to the housing base 4a of the insulating material housing via a lower pin 16 arranged on the housing base 4a.

  • the projection 7 connects to the spring carrier part 15 "On or take the projection 7 and a housing wall of the housing cover 4b the spring carrier part 15" between them figure 3 shown example, however, no spring carrier part is formed, so that the spring carrier 15 corresponding thereto is completely contained in the housing base body 4a.
  • a lower pin 16 is formed on the spring carrier part 15 ⁇ of the housing base body 4a and is intended to interact with the lower blind hole 16g in the projection 7 on the housing cover 4b in order to enable the housing cover 4b to be connected to the housing base body 4a.
