Definitions

  • the invention relates to a switchable bar, as is used above all in low voltage technology.
  • Switchable strips usually have the shape of elongated cuboids and essentially consist of a lower part, two side walls, a cover, a switching mechanism and power connections and contacts inside the cuboid, as well as a switch lever that can be actuated from the outside and can be moved in the longitudinal direction of the cuboid.
  • On one of the small faces of the cuboid are the connections - also called "outlet" in technical terms - for the respective consumer.
  • the opposite end face generally remains open or is given a protective cover.
  • Such a switchable bar is mounted transversely on busbars running generally horizontally on a wall. When the switchable bar is actuated by means of the switch lever, it is moved in the vertical direction. Relevant safety regulations require that the contacts inside the switchable bar are closed when the switch lever is up (switch position "on”), and that the switch contacts inside the switchable bar are open when the switch lever is down (switch position "off) ").
  • switchable strips in which the A-B transition from top to bottom or vice versa are modified can, but the associated conversion measures are time consuming and cumbersome.
  • Switchable strips are also known, in which fuse links and / or contact blades are attached to the cover, which is lifted off the side parts with the aid of the switching lever when the strip is switched off, or is placed on the side parts when the switch is switched on, but the position can also be used for these strips the departure cannot be changed in a simple manner.
  • the technical problem to be solved now is to develop a switchable bar, for which the point of departure (side, top or bottom) can be freely selected during assembly and can be easily changed again after assembly.
  • the shift lever is an angle lever with a first lever arm and a second lever arm, which are rotatably fastened at their connection point via a web on the cover, and in that the cover and / or the angle lever have connection and guide elements of a switching mechanism , whose counterparts attached to the lower part and / or to the side parts, as well as all other connecting parts arranged on the lower part or the side parts, are formed symmetrically to the cover, and that the cover with the parts attached to it can be separated from the lower part and the side parts. It is particularly advantageous if, according to the invention, the symmetrical design of the switching mechanism is provided with respect to a 180 ° rotation about an axis of symmetry which runs perpendicular to the plane of the cover.
  • Such a switchable strip has the advantage over all previously known switchable strips that after a separation of the cover with the parts attached to it from the lower part and the side parts attached thereto, the latter are rotated by 180 ° relative to the cover and because of their rotational symmetry again with the cover and the attached parts can be put together.
  • the outlet connection can be attached on the front (one side) or on the side.
  • the counterparts of the switching mechanism consist of slots, grooves and bulges which are essentially perpendicular to the plane of the cover and open on the cover side and which are substantially perpendicular to the cover parts, in the corresponding cams or Engage the pin of the angle lever and / or the webs attached to the cover.
  • This arrangement of the switching mechanism on the side members has the further advantage that in the interior of the switchable bar, especially in the area of the switching mechanism, sufficient space remains for the fuse links, contact springs and connecting elements, so that the E of the switchable bar inbauumble comparatively low is maintained.
  • a further advantageous embodiment of the invention consists in further grooves parallel to the grooves of the switching mechanism, in which guide webs attached to the cover can slide, which prevent the cover from tilting against the side parts and the lower part when the switching lever is actuated.
  • the angle lever is designed as a double lever and thus consists of two angle levers constructed in mirror image to one another, which are connected to one another by a handle at the free end of the second lever arm.
  • This handle advantageously has the form of a rod, tube or open profile.
  • all other parts of the switching mechanism are expediently constructed in mirror image of one another. The forces acting when the shift lever is actuated are thus transmitted evenly to both side parts and the cover, which engages in a corresponding manner via two opposite connecting webs with pins located in the opposite, matching bores of the angle lever designed as a double lever.
  • the two opposite angle levers are advantageously arranged on the inside of the side parts.
  • two connecting webs are attached, which protrude parallel to the side parts into the interior of the switchable strip and have pins attached to their ends are, which engage from the inside through suitable bores of the two angle levers and into a slot arranged in the middle of the side parts and running perpendicular to the cover plane.
  • the two opposite angle levers are thus rotatably connected to the cover at the junction of their respective first and second lever arms against the cover.
  • Each angle lever has a cam at the free end of its first lever arm, which is slidably arranged in a groove parallel to the slot mentioned and / or in a bulge arranged perpendicular to it.
  • the angle between the lever arms of the angle lever is defined as the angle between the lines connecting N-ockenstofftician Zapfenmit Center point and center point of the center of the handle attachment. This angle is advantageously in the range between 80 and 120 ° and is preferably 100 °.
  • the recesses on the lid edges can also serve as stops for the second lever arm.
  • the stops are expediently chosen so that at one stop - the center of the cam is further away from the cover - than the center of the pin, while at the other stop the center of the cam is closer to the cover than the center of the pin. It is advantageous to ensure at the same time that the angle between the first lever arm and the plane perpendicular to the groove and slot corresponds to the value at the first stop at which the cams and pins can slide simultaneously in their groove or slot; while at the second stop this angle is smaller so that the cam must be in the bulge.
  • the length of the connecting web on the cover is to be chosen so that the cover just lies on the side parts at the second stop.
  • the switch-on process takes place in reverse.
  • the force on the shift lever acts in the opposite direction and causes a torque on the angle lever.
  • the support point of the cam and thus the axis of rotation are now on the opposite side of the bulge.
  • the bulge is somewhat wider than the groove and the diameter of the cam. This ensures that, at the start of the switching-on process, the cam does not get into the groove above the bulge and is then no longer rotatable, but instead is immediately moved into the bulge and is supported on its upper side.
  • a catch is attached to the cover, into which a cam arranged on the second lever arm can snap. Since with this stop the cam of the first lever arm and the pin can slide simultaneously in the cover-side open groove or in the cover-side open slot, in this position the cover with the parts attached to it, i.e. be separated from the side parts with the fuse links and the double lever, the angle lever being held in this position by the catch.
  • this detent is designed as a double detent, the normal "off" position of the switchable bar being given when the detent cam of the second lever arm rests in the first detent, in which the angle of the first lever arm relative to the groove and Slot vertical plane is smaller than the angle at which the cam of the first lever arm and the pin can slide simultaneously in the groove or in the slot. Only when the locking cam of the second lever arm rests in the second locking, is this angle so large that the cover with the parts attached to it can be separated from the side parts.
  • FIG. 8 shows the U-shaped cross-section of the switchable bar with the lower part 23 and the side parts 9, 9 'forming the legs of the "U", which are also again a mirror-image of the cover 13 and the angle lever 3 with respect to the plane II-II .
  • a handle 17 in the form of a tube connects the angle lever 3 on this side with a mirror image Angle lever 3 'on the opposite side part 9', which is also constructed in mirror image, to form a double lever.
  • the guide webs 12 of the cover 13 are engaged in their full length in the grooves 11 of the side part 9, the cam 4 on the lever arm 1 1 lies in the bulge 8 of the groove 7, and The full length of the cover 13 rests on the side parts 9, 9 '.
  • the angle lever 3 is at the laser g erzapfen 5 of the connecting web 14 against the lid 13 pivotally connected thereto.
  • a force on the handle 17 of the angle lever 3 in the direction of the arrow 18 causes a torque with respect to an axis that is perpendicular to the plane of the side parts 9, 9 ′ and runs through the point of contact of the cam 4 in the bulge 8.
  • the angle lever 3 rotates about this axis, at the same time the support point of the cam 4 slides deeper into the bulge 8, and the bearing pin 5 slides in the slot 6 open on one side in the direction of the opening and thereby the cover 13 of the switchable strip from the side parts 9 , 9 'takes off.
  • the guide webs 12, which slide in the grooves 11, prevent the cover 13 from tilting with respect to the side parts 9, 9: fuse inserts 19 fastened to the cover 13 with contact blades 20 slip out of the contact springs 21 fastened to the lower part.
  • Figure 2 zei g t.die switchable strip in the off state.
  • the latching cam 16 is located in the latch 15, the bearing pin 5 is located closer to the open end of the slot 6 in comparison to its position in the switched-on state and the cam 4 of the short lever arm 1 is located with its entire diameter in the groove 8 and lies on the basis of.
  • the blade 20 of the fuse links 19 are pulled out of the contact springs 21 and the lid 13 can be separated together with the angle levers 3 and the fuse links 19 ste from the remaining part of the switchable LEI.
  • the guide webs 12 slide out of the grooves 11 of the side parts 9, 9 ′, the cams 4 slides in the groove 7 and at its open end, and the journal 5 slides out of the open end of the slot 6.
  • FIGS. 1 and 2 illustrate the operation of the switching mechanism. Partial views of FIGS. 1 and 2 are shown in each case.
  • FIG. 4 shows the lever arm 1 in FIG Switch position "on".
  • the cam 4 of the lever 1 lies in the bulge 8 of the groove 7.
  • the angle ⁇ 1 between the connecting line 26 center of the cam-center pin and a plane perpendicular to the groove 7 and the slot 6 is smaller than the angle ⁇ 2 between the connecting line 26 and the level mentioned, when the switchable bar is in the "off" position.
