Definitions

  • Terminal for connecting an electrical conductor
  • the invention relates to a connection terminal for connecting an electrical conductor to a terminal lug of an electrical contact, for example the terminal lug of a NH fuse contact in a fuse or house connection box.
  • Terminals for connecting a conductor of a cable to a terminal lug (connecting rail, flat rail, circuit strip) of a contact of a switching device are known in different versions as block terminals, flat direct terminals and box terminals.
  • the block clamp consists of a lower clamp part which is firmly connected to the terminal lug of the NH fuse contact and a clamp upper part which is arranged by means of two screws and forms a clamp channel with it.
  • the upper part of the terminal must be loosened from the lower part so that it can be swiveled away from it by one of the two screws so that the end of the conductor is inserted and the upper part of the terminal is then swung back over the inserted end of the conductor and screwed back to the lower part of the terminal can.
  • the box clamp also known as V-direct clamp, for a V-shaped connecting rail is formed from a hollow profile-like closed lower clamp part with a V-bed and a clamped upper part held thereon, which has a clamping jaw to form a clamping channel with the V-bed of the Has lower part of the clamp for receiving the conductor.
  • the clamping jaws can be moved perpendicularly to the axis of the clamping channel by means of a threaded bolt.
  • the box terminal is pushed to connect the conductor to a connecting rail (connecting lug) with a V-shaped cross-section into a parking position on the relevant cable core and, after the conductor has been positioned in the connecting rail, is pushed back over this and the connecting rail and then the conductor is actuated by actuating the threaded bolt between the connecting lug and the jaws fixed.
  • a connecting rail connecting lug
  • the conductor is actuated by actuating the threaded bolt between the connecting lug and the jaws fixed.
  • the flat direct connection terminal for use in house connection boxes, cable distribution cabinets and station distributors consists of a lower terminal part and an upper terminal part with opposing clamping surfaces to form a clamping gap or clamping channel formed which are held together by means of a screw or a stud and are movable relative to each other.
  • This terminal also has to be largely connected to a conductor. be dismantled in order to be able to be positioned.
  • connection of a conductor to a lug of an electrical contact with one of the connection terminals described above leaves nothing to be desired with regard to its handling or also with regard to the positioning of the conductor.
  • connection formed in a known manner from a terminal lower part engaging on the connecting lug or a support part for this and a terminal upper part held thereon to form a clamping channel for the conductor, in which the terminal upper part has a clamping jaw movable by screwing means perpendicular to the axis of the clamping channel, is after Claim 1 designed according to the invention in such a way that the lower clamp part, the upper clamp part and the connecting lug or the supporting part form a unit in which the upper clamp part parallel to the axis of the clamping channel between a receiving position in which the lower clamp part is free for receiving the conductor, and one Clamping position in which the inserted conductor is covered by the upper part of the terminal, is slidably arranged on the lower part of the terminal.
  • the receiving position of the upper part of the terminal is given on the side of the lower part of the terminal facing the contact.
  • the terminal is easy to use and does not need to be dismantled to connect the conductor.
  • the conductor can be inserted into the lower part of the terminal in a simple manner when the upper part of the terminal is displaced and can then be reliably fixed to the connecting lug by pushing back the upper part of the terminal into a clamping position given above it and then actuating the screwing means.
  • the object according to the invention allows further clamping positions between the receiving position and the most distant clamping position, so that the clamping position can be selected or adapted to the position of the end region of a cable inserted in the terminal, so that the axial accuracy of the same is only subordinate Role play.
  • the lower clamp part can be U-shaped transversely to the axis of the clamping channel and have on its legs between the receiving position and the clamping position parallel to the axis of the clamping channel formed guide slots for sliding elements formed on the upper clamp part.
  • the upper clamp part is advantageously arranged between the legs of the lower clamp part and has a base plate on which sliding elements for the guide slots are formed and on which a clamping jaw is held with a threaded bolt which is movable perpendicular to the axis of the clamping channel formed.
  • the sliding elements can have a rectangular cross section in order to prevent undesired pivoting or tilting of the upper terminal part.
  • the upper part of the terminal can thus be moved in the area of the guide slots parallel to the lower part of the terminal into a contact-side receiving position for the conductor.
  • the contact-side end of the guide slots can be widened into an annular recess so that the sliding elements - and thus also the upper part of the clamp - can be pivoted in the receiving position.
  • This design enables the overall length of the lower part of the terminal to be shortened.
  • a recess can be formed with a link guide, through which the upper part of the clamp can be pivoted by 90 ° in relation to the clamped position.
  • This design also allows the overall length of the lower part of the terminal and thus that of the connecting terminal to be shortened.
  • locking elements can be arranged on the lower part of the clamp. This further improves the handling of the connection terminal.
  • the connecting terminal can also be designed as a unit consisting of a lower terminal part, an upper terminal part and the connecting lug or the supporting part with a terminal upper part which is immovable relative to the lower terminal part, the lower terminal part being displaceable between a defined receiving position and a clamping position for the conductor is arranged on the connecting lug or the support part.
  • the connection terminal is easy to handle. After positioning the conductor with the connecting terminal in the receiving position and then moving it into the clamping position, the conductor can be reliably fixed by actuating the upper part of the terminal.
  • the connecting lug or the supporting part can at the same time be designed as a guide for the lower clamp part and have stop elements for defining the receiving position and the most distant clamping position.
  • the clamping surface of the clamping jaw and / or the connecting lug can be finely grooved on the side facing the clamping surface.
  • cutting ribs can be arranged on the clamping jaws and / or on the connecting lug, preferably transversely to the longitudinal axis of the clamping channel, which insulate the conductor when it is fixed in the connecting terminal reliably penetrate actuation of the upper part of the terminal and establish electrical contact with it.
  • These cutting ribs are advantageously formed in one piece on the clamping jaws and / or the connecting lug. This design of the clamping surface eliminates the need to deposit the conductor.
