Definitions

  • the invention relates to a power switch, consisting of a housing with a lower part and attached side walls and with connections for busbars, from one relative to the housing, transverse to the longitudinal and transverse axis movable cage with it arranged fuse links and guide bars and from a gear lever with at a distance mutually arranged pivot and bearing pins, which in complementary and parallel first and second recesses in the side walls of the housing, the second recess is open to the upper edge of the housing on the lever side and at the opposite, inner end of the second recess, a storage pocket for non-positive Support of the bearing pin is provided on the shift lever and a plate-shaped on the shift cage Shift lock unit is arranged with at least one inner locking cam, which in a Sliding groove is guided in the side wall of the housing.
  • NH fuse-links are switched with such load-switching strips, and they are used for this purpose Low voltage distribution of energy supply companies in industrial companies and large buildings used. In addition to protecting the connected circuits, these devices have also the task of carrying out certain systems or power supplies over a safe isolating section during inspection work switch off voltage.
  • an improved power switch of the type mentioned has an inexpensive one Arrangement of the pivot and bearing pins on the one hand and the complementary recesses in the side walls of the housing measures, on the other hand, provided that even when switched off Condition a small footprint is achieved and switching with low operating forces is possible, although, for example, three fuse links are switched simultaneously can.
  • Sizes 1 to 3 works.
  • size 00 safety edges guidance problems can occasionally occur occur, and in particular the measures to lock the switch cage, for example in the park position, not with the known locking unit with the movable buttons and Lugs are ensured.
  • Known Safety edges of sizes 1 to 3 have a width of 100 mm, for example, while the corresponding width with a size 00 safety edge is only 50 mm.
  • a user only wants to replace fuse links and out of the off position do not get into the parking position, an inexperienced user may that when opening from the on position by the swing of its switching movement over the Switch-off position unintentionally reaches the third parking position.
  • a locking unit articulated with movable buttons and latches.
  • the locking lugs are with recesses in the side wall of the housing can be brought into locking engagement.
  • the well-known plate-shaped shift lock unit also called locking unit, is parallel and flat next to a phase partition of the switch cage and is supported by this.
  • the well-known shift lock unit is for its operation even pivoted to this phase partition via pivot points.
  • the switch cage can also be used with a 00 size load switch Switched on position in the off position and then pulled out into a parking position and there so that the shift lever is parallel to the housing, especially in the park position, i.e. is arranged parallel to the upper edge of the housing on the shift lever side.
  • the switching lock unit advantageously takes over the effects of a phase partition.
  • only a single shift lock unit is used for a load switching strip provided here.
  • the switch lock unit Due to the switch lock unit, the user does not switch to the off position, park position, without authorization or switch-on position. This provides the possibility, also from the off position, if, for example, a machine has been switched off, an accidental restart to prevent, for example, risk of injury to a worker working on the machine prevent.
  • the pivot can be attached to the shift lever or to the shift cage. He will be in a first elongated recess in the form of an elongated hole in the side wall. At a distance from The trunnion is located on the pivot pin, for example on the gear lever, and is in a second one Recess with the bearing pocket for non-positive support of the bearing pin.
  • the Storage pocket extends a little from the second recess in the direction of the longitudinal axis of the housing while the second recess moves in the direction of movement of the switch cage Extends a bit and then ends so that the bearing journal emerge from the second recess and can move freely, namely to apply the shift lever to the upper edge of the housing and back. That is why the second recess is also open to the outside.
  • the outside is outer, front side, which the user sees first when opening the control cabinet. Therefore the storage pocket is located further inside in the direction of the user's eye.
  • the plate-shaped switching block extends essentially in the direction of view of the user, that is, from the outside in.
  • the end of the plate-shaped shift lock unit is consequently the at least one inner one Locking cams.
  • the inner locking cam engages perpendicular to the direction of movement of the switch cage into a sliding groove in the side wall or comes into locking engagement with the same through a stop or similar. Before or after the locking engagement, the inner locking cam slides in the sliding groove, which is located in the side wall and is also in the direction of movement of the switch cage, i.e. perpendicular to the longitudinal and transverse axes of the housing.
  • the plate-shaped shift lock unit itself becomes a phase partition.
  • the plate-shaped switch block unit guided with the switch cage, always between two fuse links, if these are used.
  • Shift lock unit In contrast to the known switch lock unit, also called a locking unit Shift lock unit according to the invention designed simpler and yet highly effective. She is provided with a toggle button at its outer end. The user only needs to take them and can thus move the plate-shaped shift lock unit in the permitted direction, namely swivel about a tilt axis.
  • the bracket of the outer locking cam of the shift lock unit is bendable, so that a tilting movement is made possible.
  • the shift lock unit is held through a hole in the side wall of the switch cage, through which the outer locking cam extends extends. If you have this with tolerance or a small distance of 0.1 to 2 mm, preferably 0.5 to 1 mm, can engage in the hole in the cage wall, you can switch the switching unit around the resulting tilt axis swivel or tilt.
  • the power switch strip according to the invention has a forked locking guide at the outer end of the sliding groove with stops.
  • the sliding groove is located in the side wall on the lower part. It is easy to make stops at desired locations in the groove in the groove.
  • the least an inner locking cam of the shift lock unit is guided on the one hand in the sliding groove, on the other hand, can only move up to the intended stop because of this Sliding movement is in the way.
  • the locking guide is bifurcated for alternative movement options pretend.
  • the tilt axis allows tilting of the shift lock unit both in one direction as well as in the other. This allows the inner locking cam to be moved to one or the other side of the locking guide, which of course with the sliding groove communicates.
  • the inner locking cam then against hits the first stop and is stopped there.
  • the inner locking cam can then pull out the Allow switch cage, for example in a parking position.
  • Further stops can be provided there be to further pull out and / or push in the locking cam and thus the To prevent switching cage. For example, you can use these stops to define the parking position.
  • the two guide tongues extend from the bottom or inside of the switch cage only a small distance to the inside, for example 5 to 25 mm, preferably 10 to 15 mm. It must be ensured that neither of the two guide tongues up to the space inside comes between two fuse links, because this space is already from the plate-shaped Shift lock unit is taken, the height of which is approximately equal to the height of the side wall the housing is as described above. Arrangement, mounting and actuation options of the Thanks to the two guide tongues, plate-shaped shift lock units are also excellent for one 00 size load switch.
  • the forked Locking guide in continuation of the sliding groove has two groove branches forming the fork, one of which ends in a storage bag.
  • the forked Call the locking guide V-shaped In top view of the sliding groove you can see the forked Call the locking guide V-shaped, with the lower tip of the V at the transition point between the locking guide and the sliding groove.
  • the inner locking cam can slide outwards along the sliding groove or alternatively inwards and in the event of sliding outwards, when the switch cage moves from the on to the off or even pushed into the park position, from the sliding groove directly into one or forward another groove branch of the locking guide.
  • the slot branches In which of the slot branches he slides depends on the position of the plate-shaped shift lock unit, which is in the longitudinal direction of the housing can be tilted forward or alternatively back.
  • a storage pocket arranged parallel to the longitudinal axis of the '' Housing extends and is open on one side, i.e. on this open side in the groove branch empties.
  • the latching cam can thus get into the storage pocket from the sliding groove via the groove branch and vice versa.
  • both groove branches are at least partially in Extend outwards to the upper edge of the housing on the shift lever side and a slot branch runs freely outwards to this upper edge.
  • the latter is the slot branch, that doesn't end in a storage bag. Rather, this groove branch is on the outside on the upper edge of the housing so open that the locking cam on sliding outwards from the sliding groove this slot branch can slide completely out of the locking guide, with the result that the Switch cage can remove from the housing.
  • the shift lock unit has a plate shape.
  • the main part is a rectangular plate with two longer, opposite narrow edges and two shorter, perpendicular to them narrow edges.
  • the at least one outer edge is located next to the outer narrow edge Locking cams. This protrudes over the longer narrow edge perpendicular to this in the plate plane in addition, approximately in the area of the outer short, narrow edge. Through this very outside
  • the cam axis also runs the tilt axis, which has already been described above.

  • the outer locking cam is located so that the shift lock unit can be installed particularly easily on a support bar, and this is through a recess in the plate of the shift lock unit in Area of the outer locking cam formed.
  • the supporting web can bend slightly, so that the outer locking cam by a fraction of a millimeter, possibly up to 2 mm, from the narrow longer edge can be moved outside inwards. This can be additional be favored by an insertion bevel on the outside of the locking cam. So you can more easily insert the outer locking cam into the hole mentioned in the side wall of the switch cage. In this way, the shift lock unit is securely in the side wall above the locking cams of the switch cage.
  • the outer locking cam extends in the same direction as the inner one Locking cams or parallel to this direction of extension.
  • two are located opposite one another Narrow edges of the plate-shaped shift lock unit each have an inner and an outer locking cam attached.
  • an outer and an inner locking cam on the shift lock unit are sufficient, But this works particularly cheaply if four locking cams are provided, one outer and one inner detent cam on each of the two longer, opposite one another Narrow edges. The attacking forces are then halved and prevented by the symmetrical structure of any jamming.
  • phase partition according to the invention is advantageously flexible. On the inside of the switch cage is one side attached to the phase partition, and the end of the phase partition opposite this side can be bent freely to a certain extent and also carries a stop.
  • the phase divider is bent to disengage the stop by an operating lug attached to at least one cheek of the shift lever and so is attached above that when pivoting the shift lever and thus the cheek Actuating nose runs against the phase partition and bends it so that the stop of the cover is disengaged.
  • You can in this way in the locked position Relieve the forces acting on the shift lock unit, for example distribute it in half.
  • the locking guide with a stop for example a stop in the area of Storage pocket, intended for locking by the inner locking lugs of the shift lock unit, then the lock against pulling out and pushing in the switch cage would be asymmetrical, so that tilting of the switch cage in one direction or another is not excluded would.
  • the cover on the lower part of the housing is like a counter-stop to the stop against the phase partition and thereby prevents the switching cage from moving relative to the housing.
  • a sliding groove is preferably not only present in one side wall, but also symmetrically on the opposite side wall, especially since the housing in Cross-section has a U-shape and thus the opposite two inner locking cams in the two then opposite sliding grooves run and controlled by these in their movement can be.
  • An assembly of the new load switch and in particular the plate-shaped switch block is simple and convenient.
  • the two guide plates on the inside of the switch cage are used for Example of a better introduction of the plate-shaped shift lock between the two guide plates.
  • the shift lever In operation, the shift lever is flat on the cage, and this lies on the upper edge of the Side walls so that the safety edge in the control cabinet has an extremely low overall depth Has.
  • the user opens the control cabinet, grips the shift lever and pulls this together with the switch cage to the outside, in the opposite direction of his view, to the off position.
  • the switch lock unit allows it to be pulled out to the off position by that the inner locking cams in the sliding groove to the outside until the start of the locking guide slide. There the inner locking cams run against a stop which is on the lower one Tip of the V the locking guide is arranged to think. The user must now decide whether he wants to use one or the other slot, i.e. remove the switch cage and wants to remove it from the housing or into the parking position.
  • the shift lock unit tilted so that the inner locking cams slide into the slot branch that in a storage bag ends.
  • This can be a groove guide in the form of an inverted L act.
  • the crossbar of the L forms the storage pocket.
  • the inner locking cam has the connecting corner the user no longer reaches and presses the toggle button on the shift lock unit, then it swings back into the vertical zero position, causing the inner locking cam to move in the storage bag moves.
  • This is also the parking position, in which it is possible to Swing the gear lever into a space-saving parallel position.
  • the storage bag is practical on yours provided on both opposite sides with stops such that the switch cage without actuation the shift lock unit is neither pulled out nor inwards towards the switch-on position can be pushed back in.
  • the measures according to the invention allow a switch lock unit that is simple to manufacture and stable. At the same time, this forms a phase partition in such a way that the size for the load switch 00 only a single plate is provided as a phase partition. This leave the space available to. Tilting the new shift lock unit is a very simple operation. In the side wall is a particularly simple locking guide by the measures according to the invention. To all of this is even the assembly after the manufacture and / or the fuse change the individual parts of the power switch according to the invention easier, without tilting or special Einfädelungsddling.
