Definitions

  • the invention relates to a terminal for electrical conductors for potential distribution.
  • a potential is usually distributed via a feed terminal to a large number of terminals arranged in a row, which are often also referred to as terminal blocks.
  • the distribution from the feed terminal to the distribution terminals usually takes place via a bridge element, which is often designed as a plug-in bridge for plugging into corresponding openings on the terminals.
  • the aforementioned terminals can have at least one first and one second contact.
  • such terminals often have more contacts, for example four contacts, and are usually connected to the contacts either above or below the bridge element, depending on whether a potential is to be used internally or in a periphery.
  • the terminals mentioned are designed as isolating terminals, the potential to the upper contact, ie to the first contact, can be separated for maintenance purposes simply by opening a isolating element, such as a isolating knife.
  • a conductor connected to the clamp must be disconnected for the lower contact, ie for the second contact. Disconnecting is often very cumbersome and therefore time-consuming.
  • the object of the present invention is to provide an improved clamp which simplifies the carrying out of maintenance work and also makes it safer and furthermore enables a larger area of application of the clamp.
  • the feed element which can also be referred to as a contact point or as a feed point of the terminal, for feeding in the electrical potential, can have an opening into which a pole of a multi-pole bridge element can be introduced in order to connect the potential fed in to the respective contacts via the isolating elements to distribute.
  • the feed element can be arranged, for example, centered in the terminal housing between the separating elements.
  • the multi-pole bridge element may be in electrical communication with a plurality of terminals as described herein and cross-distribute the potential into the connected terminals.
  • the multi-pole bridge element can also be electrically connected to at least one pole with a feed terminal.
  • An electrical conductor can be inserted into the feed terminal.
  • the first electrical conductor can, for example, feed current into a power grid and can have a larger cross-section than the electrical conductors that can be connected to the terminals.
  • the terminal also has two separating elements, each with at least two contacts, with a first contact of the separating elements being electrically connected to the feed element and the separating elements being adapted to be able to be switched independently of one another between a contact position in which the respective separating element makes the respective first contact with electrically connects the respective second contact to one another, and a disconnected position in which the respective disconnecting element electrically isolates the respective first contact from the respective second contact.
  • the separating elements can be constructed in the same way and can, for example, comprise a mechanically movable separating means, such as a separating blade.
  • the separating means may comprise an electrically conductive element between the first contact and the second Contact can be arranged and removed again.
  • the electrically conductive element can be moved via a mechanical switch.
  • the separating element can also comprise a fuse holder which can accommodate a fuse, such as a fuse, for example.
  • the separating element can also include a component carrier for accommodating passive components, such as for accommodating capacitors, diodes or resistors.
  • the respective first contact of the isolating elements is electrically connected to the feed element.
  • the potential at the respective second contact can thus be controlled via the respective separating element, wherein when the separating element is inserted, the respective first contact can be electrically conductively connected to the respective second contact and with the separating element removed, the respective first contact can be electrically insulated from the second contact.
  • the terminal housing can be designed as an insulating plastic housing and can be adapted to accommodate the feed element and the isolating elements.
  • the terminal housing can also have openings into which conductors can be inserted for connection to the second contacts and an opening for making electrical contact with the feed element. The electrical connection between the feed element and the respective first contacts can be established in the terminal housing.
  • the feed element is arranged on the terminal housing between the separating elements.
  • the feed element can be configured as a center feed, which can also be referred to as a center feed.
  • the central feed can be arranged at least in some areas in a bridge shaft or as part of a bridge shaft for connecting a bridge element, such as a jumper.
  • the term "central feed” can be understood as meaning a feed which is arranged between the separating elements.
  • the central feed and the respective second contacts of the isolating elements can be arranged on or on one side of the housing.
  • the terminal can also be referred to as a feed-through terminal, for example, since an electrically conductive connection can exist between the second contacts when the separating elements are closed.
  • each terminal division of a terminal described herein can carry two potentials in the future, since there are two separate marking options.
  • the marking option between the first contact and the first separation point can be divided into an upper and a lower half in order to mark the different, internal and peripheral potentials.
  • the marking option that covers the bridge shaft can also be used in combination with the marking described above to mark the different potentials. Another option for marking the different potentials is to use marking options on the side that are directly related to the respective contacts.
  • a marking which covers the bridge shaft can also advantageously prevent a plugged-in bridge element from being removed at the same time.
  • the feed element is designed at least in regions as at least one bridge shaft and is adapted to be electrically connected to a bridge element for feeding in the potential from an adjacent terminal.
  • “Bridge shaft” can be understood here to mean a contact area that lies lower than a housing surface and is adapted to be electrically connected to a pin-shaped contact of the bridge element, for example.
  • the feed element can, for example, comprise a row of pins arranged next to one another and be designed to be pluggable or screwable as a comb jumper, box jumper and/or cross connector.
  • this allows feeding via the bridge shaft, which means that there is no need to arrange a separate feeding contact.
  • the feed element is designed as an at least two-part bridge shaft and is adapted to be electrically connected to at least two feed bridges, in particular to a box jumper and/or a central feed.
  • the feed element is arranged on one side of the clip together with the second contacts.
  • the terminal can be mounted on a mounting rail with one side of the housing and the second contacts can be arranged on the opposite side for connection to corresponding lines.
  • the feed element is arranged centrally, in particular as a central feed, between the second contacts.
  • the feed element is designed as a clamp contact or screw contact for connection to at least one contact of a multi-pole bridge element.
  • the respective second contact is designed as a screw, tension spring, push-in, quick and/or bolt connection contact.
  • At least one of the separating elements comprises a mechanically movable separating means, in particular a separating blade, and/or a fuse holder, for connecting and electrically isolating the respective first contact and the respective second contact.
  • At least one of the separating elements includes a contact, in particular a plug contact, for electrical connection to a fuse plug.
  • the terminal housing includes a connection structure adapted to attach a lever type fuse holder to at least one of the disconnects.
  • This connection structure can be shaped like a joint and advantageously ensures that the pivotable lever fuse holder cannot be lost by at least 90°.
  • the articulation point can be dimensioned in such a way that it does not protrude beyond the width of the housing, but instead has the shape of an ear in the “height” housing dimension.
  • such a lever fuse holder can be added to the clamp, which makes it possible to prevent unfavorable operating conditions, such as an overload condition.
  • the terminal housing is adapted for rail mounting, in particular the housing is adapted to be fastened on a profile mounting rail.
  • the rail can have a hat-like profile and can therefore also be referred to as a top-hat rail.
  • several terminal housings can be pushed on to the side and plugged together when pushed on, or plugged together first and then plugged onto the profile mounting rail and locked.
  • the terminal housing can also be glued to a surface using an adhesive, for example an adhesive strip.
  • the second contact of at least one of the separating elements is designed in two or more parts for the connection of two or more electrical conductors.
  • the feed terminal and the terminals described herein can be easily and modularly lined up by plugging them together.
  • the potential distribution system has a multiplicity of terminals as described herein, the respective feed elements of the terminals being designed as at least two-part bridge shafts; and at least two multi-pole bridge elements, which are each designed as jumping comb bridges and can be arranged in the feed elements of the terminals in order to distribute an alternating potential to adjacent terminals.
