Definitions

  • the invention relates to a built-in switch
  • the switch lock consists essentially of a rotatably mounted contact lever and a manual control that is rotatably connected outside of its pivot bearing by a switching rod in the manner of a knee joint with the toggle lever, in detail according to the preamble of claim 1.
  • the contact lever is acted upon by a spring which determines the contact pressure and the switching force.
  • the generic term reads from the state of the art according to EP-B1-0047847.
  • the contact lever is indirectly connected to the shift rod via a ratchet lever.
  • the described prior art relates to a circuit breaker, but reference is made here to built-in switches.
  • Built-in switches can be installed in distributors and serve as hand switches for higher outputs.
  • the invention has for its object to develop a built-in switch that is simple in construction, gets by with a spring for the manual control element and for the contact force and yet has particularly good operating properties.
  • a ratchet lever rests on a ratchet with low tolerance.
  • the free adjustment of the contact-free arm of the contact lever causes the free end to be raised to a stop when it is opened, so that the movable contact piece to the fixed contact piece first performs a rolling movement and can break a welded contact.
  • an automatic adaptation to contact erosion is achieved.
  • a flexible conductor for example a stranded conductor, is led directly from the connecting terminal to the contact.
  • the contact lever can then be made of steel, which is cheaper and provides greater durability.
  • the arm length of the contact lever on the one hand from the contact to the pivot bearing of the switching rod and on the other hand from the pivot bearing of the switching rod to the free end of the contact lever or up to the stop, you can set the contact forces acting at the contact point and the speed of the contact opening in the course of the opening. If the contact lever has a shorter arm from the contact to the pivot bearing of the switching rod and a longer arm from the pivot bearing of the switching rod to the end of the contact lever, rapid opening and closing is achieved with large contact forces and a correspondingly high current carrying capacity.
  • the built-in switch 1 has a rotatably mounted contact lever 2 and a manual control element 3.
  • the manual control member 3 is connected to the contact lever 2 in a rotationally movable manner outside of its rotary bearing 4 by a switching rod 5 in the manner of a knee joint.
  • the contact lever 2 is loaded with respect to its pivot bearing 6 on the arm 8 opposite the contact 7 by a spring 9, in the exemplary embodiment a compression spring.
  • the spring 9 determines the contact pressure and the switching force.
  • the pivot bearing 6 of the contact lever 2 is formed by the shift rod 5 and guided in a backdrop 10.
  • the contact-free arm 8 of the contact lever, as measured by the contact opening path - compare FIG. 3 - can be set freely in a considerable range. In the exemplary embodiment, the setting is limited by a stop 11 and possibly by a bracket 12 of the connecting terminal 13.
  • the movable contact piece 14 can be riveted through the contact lever 2. It is preferably connected to a flexible conductor 15 which is led directly to the terminal 13.
  • the contact lever 2 has a shorter arm from the contact 7 to the pivot bearing 6 of the contact lever or the switching rod 5 and a longer arm from the pivot bearing 6 of the switching rod 5 to the free end 16 of the contact lever 2.
  • the electrical current supply takes place from the connection terminal 13 via the flexible conductor 15 to the movable contact piece 14 and to the fixed contact piece 17 to the further connection terminal 18.
  • an intermediate position according to FIG. 2 is reached when the manual control element 3 is turned clockwise.
  • the free end 16 of the contact lever 2 is raised to the stop 11, so that the movable contact piece 14 against the fixed contact piece 17 a rolling movement that also easily breaks welded contacts.
  • a pulling force initially acts on the control rod 5 via a lever arm up to a possibly welded contact 7 and, after the free contact arm 8 is in contact with the stop 11, a long lever arm from the pivot bearing 6 to the contact with the stop 11.
  • the lever arm is from Pivot bearing 6 to the point of application of the spring 19 and the short lever arm from the pivot bearing 6 to the contact 7 are decisive.
  • the contact opens rapidly, whereby the speed can be increased compared to the lifting speed of the rotary bearing 6 to the extent that the length of the arm of the contact lever between the rotary bearing 6 and contact corresponds.
  • the contact When switching on, the contact is quickly closed up to the intermediate position shown in FIG. 2 and then rolled off to the position shown in FIG. 1 at high contact pressure. Contact erosion can be compensated for by the spring 19 lifting the free end 16 of the contact lever 2, so that the movable contact piece 14 is lowered accordingly to the fixed contact 17 about the pivot bearing 6.
