Definitions

  • the invention relates to a disconnect terminal according to the preamble of claim 1.
  • the present invention is therefore based on the object of creating a disconnect terminal of the generic type which enables smooth, reliable displacement of the disconnect slide to the busbar and back from there.
  • the separating slide Due to the elongated sliding surface of the additional and separate guide part placed on the upper clamping jaw of the disconnect slide and the guidance of this sliding surface on the terminal housing, the separating slide is now guided over a relatively large area not only on the busbar but also on the terminal housing. Despite the relatively unstable state of the opened slide valve, the slide valve can now be moved in the open state without any risk of canting. This also contributes to the fact that in this embodiment the force applied by the screwdriver when the displacement force is applied is close to the newly created guide through the elongated sliding surface on the top.
  • the guide part engages behind the clamping jaws with an angle.
  • this enables particularly good force transmission of the displacement force to be achieved on the clamping jaws to be displaced on the busbar.
  • this bend if it is advantageously provided with receptacles for end regions of the clamping jaws, offers in a very simple way the possibility of counteracting an undesired mutual turning of the clamping jaws when the clamping screw is tightened. This is of particular advantage when hollow jaws are used as clamping jaws, which have a tendency to turn laterally out of the clamping plane when the clamping screw is tightened.
  • the guide part is assigned a further very important function in that it is provided on the rear with a catch for which a catch is provided on the disconnect terminal housing in a position corresponding to the zero position of the disconnect slide.
  • Disconnect terminals are sometimes arranged so that the isolating slide is located substantially vertically above the busbar and must therefore be moved towards and away from it in an approximately vertical direction. If after the disconnection of the disconnect terminal is forgotten to properly tighten the clamping screw again in the zero position of the disconnect slide, it may well happen that the disconnect slide or the like from the zero position as a result of operational vibrations. falls back onto the busbar. This is life-threatening for the operating personnel, since they believe that they are disconnected from the network and are working on the downstream devices.
  • the guide part provided ensures that the isolating slide cannot accidentally fall out of the zero position when it is installed above the busbar, even if the clamping screw is accidentally not tightened or not properly tightened.
  • the locking force can be easily measured so that on the one hand an unintentional falling is not possible, on the other hand the displaceability is not impaired, all the more, as well as the new design, if necessary, a very high displacement force without the risk of tilting or tilting the Slider can be applied.
  • the disconnect terminal shown in Fig. 1 has within its insulating material housing 1 a busbar 2, on one end of which a connection 3 is provided for a conductor.
  • a busbar 2 On the busbar 2, in the area of the other terminal side, there is also a sliding slide 4 which essentially consists of an upper jaw 5 located above the busbar 2 and a lower jaw 6 located below the busbar 2, the jaws 5 being firmly clamped together and 6, a clamping screw 8 is provided on the busbar 2 and / or a busbar 7 leading past a row of such disconnect terminals and indicated by dash-dotted lines in FIG. 1.
  • the busbar 7 brings the line voltage to the series of disconnect terminals.
  • a plastic guide part 9 is attached to the upper jaw 5 of the separating slide 4 and has an elongated sliding surface 10 on the upper side, which is guided on the inner surface of the upper boundary wall 1 of the insulating housing 1.
  • the guide part 9 also has a screwdriver guide opening 11 which leads to a receiving chamber 12 in which the screw head of the clamping screw 8 lies.
  • an elongated opening 1b is provided, in which the screwdriver at one Moving the slide valve 4 can move back and forth.
  • the guide part 9 also has an opening 13 for a test plug.
  • the guide part 9 is provided at its rear lower end with a downward-pointing bend 14 which engages behind both the upper jaw 5 and the lower jaw 6 of the separating slide 4.
  • the bend 14 has an opening 15 through which the busbar 2 can pass.
  • the bend 14 also forms a receptacle for the rear ends of the upper clamping jaws 5 and 8 by means of a laterally formed, forwardly projecting web 16, which abut laterally with their end regions on the web 16 in such a way that they tighten when the clamping screw 8 is tightened can no longer turn laterally out of the clamping plane, as can happen in particular when the clamping jaws 5 and 6 are designed as hollow jaws.
  • the guide part 9 can be clamped on the upper jaw 5.
  • a receptacle 18 is formed by means of a material shoulder 17 on the front side, which is delimited opposite the material shoulder 17 by the elastic bend 14, which is limited due to the use of plastic material.
  • the guide part 9 also has a catch with which a slight latching of the isolating slide 4 in its zero position, ie in the position inserted into the clamp, is possible at a distance from the busbar 7.
  • a female connector 19 is formed in the rear area of the guide part 9, which has a locking knob 20 on its underside at its rear end.
  • a counter-latching body 21 is integrally formed on the insulating material housing 1 of the disconnect terminal. Locking in the zero position means that with a ** .
  • Disconnect terminal arrangement vertically or approximately vertically above a busbar of the isolating slide 4 cannot inadvertently fall from the zero position onto the busbar carrying the mains voltage, even if the clamping screw 8 in the zero position was accidentally not or not properly tightened again.
