Definitions

  • the invention relates to a residual current circuit breaker or a circuit breaker with a switch for a center conductor, in which the movable switching bridge of the circuit breaker is coupled to the movable contact of the switch for the center conductor via a slide guided on the side wall of the housing of the circuit breaker, the slide being one of the Switch bridge of the circuit breaker engaging approach and at least one on the opposite side of the slide and the projection engaging on the movable contact of the switch for the center conductor and the projection is electrically isolated from the projection.
  • a circuit breaker with inevitable all-pole shutdown is known from DE-A-15 63 919.
  • a transmission element designed as a slide is provided, which is guided in grooves in the side walls of adjacent shell halves.
  • a disadvantage of this known circuit breaker is that the actuating parts (knee joint parts) of the circuit breaker must be designed with extensions that operate the slide.
  • the invention has for its object to provide a circuit breaker of the type mentioned, in which the coupling of the contact apparatus of the circuit breaker with that of the switch for the center conductor is possible without changing the structure of the circuit breaker and neither the mechanics nor the contact apparatus of the circuit breaker is too much be claimed.
  • this object is achieved in that the projection designed as a pin is the bearing pin for the joint between the switching bridge and its actuating member, a bridge tab and that the projection engaging on the movable contact of the switch for the center conductor is in a hole in the movable contact engaging pin is.
  • a cam is provided on the slide next to the pin, which bears against the back of the movable contact.
  • the pin serving as a bearing pin between the switching bridge and bridge link is a metal pin inserted into the slide.
  • a metal bearing pin ensures a stable joint between the switching bridge and the actuating element, the bridge tab, and the circuit breaker.
  • the slide designed as a plate is guided between longitudinal ribs formed on the outer surface of the side wall of the housing for the circuit breaker, and that the side of the slide remote from the housing of the circuit breaker is connected to at least one strip-like projection which is formed by the half-shell of the switch for the center conductor protrudes towards the circuit breaker, slides.
  • the housing of the switch for the center conductor only needs to consist of a half shell.
  • a circuit breaker 1 shown in FIG. 1 has a structure which is known per se and is accommodated in a housing consisting of lower shell 2 and upper shell 3 (FIG. 2). Common magnetic releases, the bimetallic release and the mechanism for actuating the contact device are housed in the housing. Since these components of the circuit breaker 1 can have a conventional structure, only the parts essential for understanding the invention are briefly explained below.
  • the adjoining the switching bridge 4 end of the hinge bracket 6 is coupled via a pawl tab 8 with a pawl 9 pivotably mounted in the housing. If the actuating button 7 is pivoted, the switching bridge 4 moves against the force of a spring 10 in contact with a fixed contact 11.
  • the switch 12 for the center conductor (FIG. 3) to be attached to the circuit breaker 1 or a group of such circuit breakers is accommodated in a housing 13 designed as a half-shell, which has the same external dimensions as the housing of the circuit breaker 1.
  • a movable contact 14 is pivotably mounted in the housing 13 via a bearing 15 formed from an eye and a bearing journal which is fixed to the housing, the movable contact 14 being pressed into its open position by a spring 16.
  • the movable contact 14 is connected to a connecting terminal 18 via a conductor cable 17.
  • the fixed contact 19 assigned to the movable contact 14 is connected to a second connection terminal 21 via a conductor rail 20 inserted into the housing 13.
  • a slide 22 is provided for actuating the movable contact 14 of the switch 12.
  • the slide 22 (FIG. 5) comprises a plate 23 which, on its side facing away from the switch 12, has a projection 24 in which a pin 25 is inserted as an extension.
  • the plate 23 On the side 30 opposite the pin 25, the plate 23 has a projection in the form of a pin 26 and next to this a cam 27.
  • the pin 26 engages in a hole in the movable contact 14 and takes it with it.
  • the cam 27 lies on the back of the movable contact 14, i.e. 3 from above against the contact 14 and relieves the pin 26.
  • it In order to give the slide 22 the necessary stability, it is equipped on its side 30 projecting into the housing 13 with a stiffening rib 28.
  • the slide 22 can be made in one piece from plastic.
  • the slide 22 lies between the guide ribs 31 (FIG. 2) provided on the outside of the upper shell 3 and the pin 25 projects through an opening 32 in the upper shell 3 Interior of the circuit breaker 1.
  • the pin 25 engages in the hole 33 of the bridge plate 5 visible in FIG. 2 and the hole in the switching bridge 4 aligned with this hole 33, so that not only the bridge plate 8 is articulated but also connected to the switching bridge the movements of the switching bridge 4 of the circuit breaker 1 are also transferred to the movable contact 14 of the switch 12 via the slide.
  • the slide 22 has a plate 23, which covers the opening 32 when the circuit breaker 1 is attached to the switch 12 for the center conductor, is moreover a transfer of ionized gas from the housing consisting of the lower shell 2 and upper shell 3 of the circuit breaker 1 in the housing 13 of the switch for the center conductor is obstructed.
  • the shells 2, 3 and the housing 13 can be connected via continuous connecting means, e.g. Rivets or the like, are connected to one another.
  • the movable contact 14 of the switch 12 follows every movement of the switching bridge 4 of the circuit breaker 1, regardless of whether this is done by the actuating button 7 or in the event of a trip Release of the pawl 9 is effected by the magnetic release or the bimetallic release by the spring 10.
  • an exact guidance of the slide 22 is ensured, so that the unfavorable tilting moments act on the moving parts of the circuit breaker 1 as little as on the moving parts of the switch 12.
