Definitions

  • the invention relates to an at least 3-pole overcurrent protection switch.
  • 1-pole overcurrent protection switches are common (DE 27 21 162 C2). It is also known to connect a 2-pole overcurrent protection switch to manufacture two 1-pole overcurrent protection switches that the functional parts of the two individual switches on either side of one transverse to the row direction extending partition positioned in a common housing are, with the moving parts of these two individual switches each shared overcurrent release mechanically with each other via thru axles are connected (DE 27 21 162 C2; Fig. 4-8).
  • the market is increasingly demanding applications in which 3 phases or 3 phases and the neutral conductor must be switched or protected.
  • Such applications can be, for example, pumps, high-pressure cleaners or motor protection in general.
  • the invention has for its object to produce such a 3- or 4-pole circuit breaker with little manufacturing effort.
  • This object is solved by claim 1.
  • two existing 2-pole overcurrent protection switches of the type mentioned at the beginning are used. These two 2-pole switches are positioned on both sides of a partition and fixed to it.
  • the intermediate wall is aligned at right angles to the row direction of the two 2-pole double switches or the single switches combined in them to form an assembly. It forms approximately a plane of symmetry for the approximately three-phase or three-pole overcurrent protection switch which is symmetrical in space.
  • the partition wall forms, so to speak, the backbone of the 3-pole or 4-pole overcurrent protection switch, which is assembled as a mounting unit and which, for reasons of language simplification, is also referred to below as Combination switch "is called.
  • this assembly unit is mounted within a housing, which surrounds the side walls of the assembly unit in the manner of a shaft.
  • the mounting unit is fixed within the switch housing after Claim 3 or 4.
  • the one located between the two 1-pole single switches Partition of one-piece part of a surrounding the two 1-pole single switches pot-like and upward for positioning the manual shift actuators are open housing, any used according to the invention, consisting of individual switches arranged on both sides of a partition Switch assembly open on both sides in the row direction to the outside.
  • the required air and creepage distances between the neighboring individual switches are within the 2-pole combined into one module Switch through their partition and between the two to the combination switch summarized assemblies determined by the partition respected.
  • the assembly unit is shielded from the outside by the housing side walls. The shielding is down through the middle Bottom edge of the partition and on both sides of it with the partition made of two two-pole switch one-piece bottom walls according to claim 7.
  • the combination switch has a common according to claim 14
  • Switch rocker like the mechanical connection of all individual switches by axially aligned axes according to claim 12 ensures that only one in the combination switch when tripping overcurrent combined single switch the entire combination switch is actuated with all its poles, i.e. in the event of an overcurrent trip triggers overall.
  • the actuation of the rocker switch can be according to claim 15 facilitated by two separate, snap-on push buttons and it always affects all individual switches.
  • the combination switch is 4-pole. It contains two lined up, drive-connected, each forming a module, approximately identical 2-pole overcurrent protection switch 1, 2, hereinafter also referred to as Switch assembly ".
  • Each switch assembly 1, 2 contains, on both sides of a partition 4 or 5 running transversely to the row direction 3, in each case a 1-pole individual switch 6-9, each with essentially identical, pivotable moving parts parallel to the partition 4 or 5.
  • Pole switch assembly 1 or 2 is positioned on one side of an intermediate wall 10 running parallel to the partition walls 4, 5, and both switch assemblies 1, 2 are connected to this intermediate wall 10 to form an assembly unit 11.
  • the moving parts described in detail below also all functionally Individual switches 6-9, described in more detail below, are mechanically connected to one another by axes 12-15 (FIG. 5) for common effectiveness.
  • the mounting unit 11 is mounted within a housing 16, which the Side walls of the assembly unit 11 surrounds in the manner of a shaft.
  • the assembly unit 11 is by means of the exposed side edges 17, 18 of the Intermediate wall 10 of fixing lugs 19, 20 (the latter invisible in FIG. 5) on the opposite housing side wall 21 or 22 (the latter invisible) snap-in fixation recesses 23,24 (the latter invisible).
  • the partitions 4.5 of a 2-pole switch assembly 1 or 2 form the core of one Carrier frame for holding the moving parts and the functional parts of the in their combined individual switches 6.7 and 8.9.
  • the partitions 4,5 of a 2-pole Switch assemblies 1 and 2 each form approximately a plane of symmetry for whose individual switches 6.7 and 8.9. They carry on their flanks on both sides in a row 3 protruding bottom walls 25 of the switch assembly 1 or 2.
  • the partitions 4 and 5 also carry a 2-pole switch assembly 1 or 2 3 rear walls 26 projecting on both sides in the row direction 4,5 carry on their sides opposite the rear walls 26 Contact ribs 28 for contacting the opposite housing side wall 21.
  • the axes used to couple the functions between the individual switches 6-9 12-15 lie loosely in the assigned functional or movement parts and are secured against displacement in the longitudinal direction 3 by the housing side walls 30, 32.
  • the mode of operation and the kinematics of the individual switches 6, 9 are such according to DE 27 21 162 C2. It is described in detail below.
  • the Manual control device of the assembly unit 11 is a row direction 3 common over the entire width of the assembly unit 11 Rocker arm 33 as a rocker switch. There are still two in the area of the lever ends 34,35 of the rocker arm 33 by one each, not shown, to the row direction 3 parallel axis for rotatable mounting snap-on push buttons 36.37 present in the longitudinal guides 38.39 of the front of the housing 40 are guided longitudinally.
  • An add-on functional part 41 can be attached to the underside of the assembly unit 11, in particular snap-on or snap-on.
  • the fixation of such add-on functional parts 41 preferably takes place on the intermediate wall 10, more precisely on the bottom edge.
  • the housing end wall 40 is a contact flange over the housing side walls 30.32 beyond.
  • the housing side walls 42, 43 are on the outside with Resilient locking arms 44 for snapping the assembly unit 11 into a panel (not shown) provided.
  • the axis 14 is fixed performed in the rocker arm 33. It runs perpendicular to the image plane of FIGS. 2 and 3, namely in the row direction 3. It passes through the latching lever 57 in a groove 60 and this groove 60 has the shape of an upside down V.
  • the rocker arm 33 is rotatable about the axis 13 on the base 51 or on the partition 4 rotatably supported and by the return spring 61 with a in the off position directed permanent pressure.
  • a different torque is effective for this pressurization, which the contact spring 53 exerts on the latch lever 57.
  • This opposite Torque ensures in the on position, i.e. when resting on the stop 58 Latch lever 57 to ensure that the axle 14 does not cross the apex 62 of the V-shaped groove 60 can slide away.
  • the contact separation that is, tripping or switching off of the device, by acting on the effective end 63 of the angle lever 59 with a force that is exerted, for example, by a current Bimetal 64 or through the opening tappet (not shown) of an attachment 41 is effected.
  • the detent stop 58 of the angle lever 59 is the result a rotation of the angle lever 59 counterclockwise around its Pivot axis 65 from its support position for the detent 66 of the latch lever 57 swung away. This releases the latch lever 57, so that the torques generated by the axis 14 and the contact spring 53 the contact opening cause.
  • the force acting on the angle lever 59 is eliminated, for example through the bimetal 64 or the plunger of the add-on functional part, so the Angle lever 59 reset by the torsion spring 67, so that the switch is switched on again (contact closing position).
  • the latching lever 57 is U-shaped so that it surrounds the base 51 or can reach around the partition 4 or 5.
  • the closed end of the U lies in the area of the detent 66.
  • the angle lever 59 also extends through one Opening the partition 4 or 5 with an axial extension 68, where the other Pole of the switch assembly is positioned or can be attached.
