  • the invention relates to a blow-out system for a "Plug-in" - or plug-in component and in particular relates the invention the blowout system of a circuit breaker or a circuit breaker that are designed as such a plug-in component.
  • Control centers or central points of electrical installations are usually arranged in a row of individual components put together on a top-hat rail and then the purpose of regulations or according to the function of the electrical installation wired.
  • the in the Usually for functional components are standardized in Germany, for example, that in The component is installed on the input side at the bottom and the exit side of the component is up.
  • the components are assembled on one Mounting rail, because of its hat-shaped profile is called a hat rail.
  • the individual components are snapped onto the profile and locked there, the profile reminiscent of a hat brim Profile sections of the DIN rail partially encompassed become.
  • a resilient section as a locking section on the housing of the respective component can the profile section when inserting the component dodge springily and then reaches behind Profile section.
  • the subsequent wiring is done then on screw terminals of the component.

  • the movable contact is with a drive system connected, which is a key switch, a spring-loaded Lever mechanism or other drive system can be.
  • a trigger mechanism in the circuit breaker provided that the drive system at Occurrence of a trigger criterion for separating the Triggers contacts, whereupon the movable contact of the fixed contact and the circuit through the Miniature circuit breaker is interrupted.
  • the trigger mechanism usually detects the occurrence an overload and / or an overcurrent as possible trigger criteria.
  • To detect the overload is the circuit breaker with a bimetal strip provided by the current to be monitored is flowed through and becomes overloaded, i.e. a while to a somewhat longer period of time high current, bends until it drives the drive system Separation of the contacts actuated, i.e. triggers.
  • For the Overcurrent i.e. a short-term occurring high Electricity is usually used as a trigger mechanism Magnetic system that uses an anchor and one of the coil through which the current to be monitored has flowed. A correspondingly high overcurrent occurs in the coil on, so the armature is generated by the magnetic field shifted against the force of a resilient element and triggers the switch.
  • the contacts are through the drive mechanism separately.
  • a deletion sheet package in is to be deliberately deleted the circuit breaker provided.
  • a blow-out duct can be removed from the gas.
  • free metal ions should be discharged or in a predetermined area of the component housing be carried out, for example, to prevent at an undesired location in the component housing forms a metallic layer.
  • the exhaust duct to be interpreted so that the escaping gas is a certain dielectric strength is reached.
  • the component housing usually has the shape of a flat cuboids.
  • the cuboid has one in the installed position Back, one opposite this front, which is usually also the control element side of the component is, and has narrow sides above and below as well Side surfaces left and right, which are usually the have the greatest extent.
  • the front usually wears Operating and display elements. Often this is Control unit designed as a toggle, which is a manual Allows opening and closing of the contacts.
  • the toggle position is usually used in conjunction with a Marking on the gag as a display device for the Switching state. Screw terminals for electrical connection the switch are usually also from accessible from the front. Since the front is the Visible side in the installation position, are there for the Labeling the switch suitable labeling fields intended.
  • the contacting i.e. the electrical connection is made near the edges of the back that are attached to the Border narrow sides.
  • the contact tongue of the plug component stands perpendicular to the back of the Reverse front, being the main plane of the contact tongue aligned parallel to the main plane of the narrow sides is.
  • the sliding bolt is against the force of a resilient or latching element, in one piece on the sliding latch itself or is formed on the housing, parallel to the main plane the back can be moved in grooves on the component housing guided.
  • In the back of the component housing is also a receiving groove for receiving a Mounting rail (top-hat rail) molded from plastic.
  • the receiving groove and the sliding lock are like this coordinated that the mounting rail in the Recording groove is included and the slide lock on Prevents the mounting rail from coming out of the groove, by sliding the slide latch with one edge of the mounting rail is engaged.
  • Fig. 1 shows a schematic representation of a Top view of a section of a housing half a corner of the housing in which a contact tongue 40 a plug-in component is included. simultaneously this corner is the corner of the housing in which the recordings 14 trained for a quenching plate package (not shown) are.
  • a quenching plate holder 15 is the end of Extinguishing sheet package assigned, which the to be separated Contacts (not shown) is turned away. To the quenching plate holder 15 is followed by a blow-out duct 50, which will be explained later.
  • the housing half-shell 10 has an outer wall 11, which surrounds the housing shell all around.
  • a receiving groove 16 for one Molded mounting rail.
  • the contact tongue 40 has a angled shape in which sections 43, 44 and 42 successively at right angles to each other extend.
