Definitions

  • the invention relates to a switchable bar, as used especially in the low voltage range.
  • Such strips essentially consist usually of a housing in which on the one hand the contacts and electrical connections of the fuses with the busbars and on the other hand, the contacts and electrical connections of the fuses with a arranged on a front side terminal area, also called outlet done.
  • the switchable strips have the design of an elongated cuboid and are usually mounted perpendicular to the horizontally extending busbars.
  • On the housing usually a lid is mounted, which covers the current-carrying parts and in which the fuses are mechanically attached.
  • the cover In a position of the handle referred to below as a third position, the cover is usually moved a short distance further. This position is locked by a safety mechanism such that unintentional operation is made difficult or prevented.
  • the guide elements of the lid are designed so that it can be removed from the housing in this third position. In the now exposed cover, the fuses can be easily replaced.
  • switchable strips are usually used in single or three-phase design, ie with one or three fuses, used in cabinets in the low-voltage supply, the switchable strips are arranged side by side. To allow cabling from both above and below, the enclosures are either inserted with the clamp side up or down. Therefore, some safety edges are designed so that the insertion of the cover relative to the housing in two positions is possible to comply with the prescribed in standards movement direction of the handle in both mounting positions.
  • Mechanisms for power amplification are built to eliminate this deficiency, which allow movement as a tensile or compressive movement in an ergonomically favorable manner.
  • An exemplary embodiment of this kind is in DE 100 14 055 disclosed. When NH fuse switchgear shown there, the motive force is reduced by a lever arrangement.
  • Another disadvantage is that there is no safety mechanism preventing inadvertent movement to the third position.
  • the object of the present invention is to improve the operability of the switchable bar in such a way that an easy insertion of the lid is made possible, an ergonomically good arrangement of the handle takes place, a reduction in operating forces is achieved and easy to use, but safe against unintentional Operation protective safety mechanism is present.
  • the lid is slidably supported by large-sized guide elements and is brought in operation of the handle by a curved lever arrangement in the required positions.
  • the third position is protected against unintentional actuation by a safety mechanism integrated in the lever construction.

  • Fig. 12 An isometric view of the handle 3 with not pressed button
  • Fig. 13 An isometric view of the handle 3 with pressed button
  • FIG. Shown are the main components of the switchable bar in the switched-on operating state.
  • the housing 1 is mounted on a lower part 29 , which at one end face a terminal block 4 not described in detail here , in the jargon also called “departure” has, to which the wires of the electrical consumers are connected.
  • the housing 1 is covered with a cover 2 , whereby all electrical elements present in the housing 1 are secured against contact.
  • a handle 3 is pivotally mounted, by pulling or pressing on the gripping surface 22a and 22b can be actuated, whereby the switch-off position is reached.
  • By pressing the button 9 while pulling the handle 3 of the safety mechanism is actuated with the third position is released to remove the lid 2 .
  • Fig. 2 shows the switchable bar with the cover removed 2 with the arrangement of the fuses 26 and electrical connections 27 and the busbar used in the lower part 29 contact 28, in technical language also called "entrance”.
  • Fig. 3 shows the switchable bar in the off position.
  • the cover 2 is slidably guided by guide columns 15a and 15b in the housing 1 in guide channels 20a and 20b .
  • the central arrangement of the two guide columns 15a and 15b ensures that in particular a lateral or diagonal tilting of the lid 2 during the opening and closing movements is avoided.
  • the lever 6 is rotatably mounted in the lid via a bolt-shaped axis 14 located on this and has on the handle 3 side facing a bolt-shaped projection 11 which engages in a backdrop-shaped opening 8 in the handle 3 and on the other, the housing. 1 facing side, also a bolt-shaped projection 12 which engages in a backdrop-shaped opening 7 in the housing 1 .
  • Fig. 4 shows the switchable bar in the third position, which can be achieved by pressing the button 9 .
  • FIGS. 5 to 7 The function of the leverage effect can be seen in detail with reference to FIGS. 5 to 7 .
  • Fig. 5 In the closed position in Fig. 5 is the bolt-shaped projection 11 of the lever 6 at the left end of the backdrop-shaped opening 8 in the handle 3.
  • the lever 6 By the pivotal movement of the handle 3 , the lever 6 is rotated about its axis 14 in a clockwise direction, the bolt-shaped approach 11 of the lever 6 along the backdrop-shaped opening 8 in the handle 3 slides.
  • This breakthrough is designed by juxtaposed curves so that at the beginning of the movement path, the rotational movement of the lever 6 is reduced and increased at the end of the movement path becomes. This ensures that the lever ratio at the beginning of the movement, in which the contact pressure must be overcome and at the end of the movement in which a high travel of the lid 2 is desired, is changed advantageously.
  • the bolt-shaped projection 12 of the lever 6 is moved in a similar manner by the rotational movement of the lever 6 in the backdrop-shaped opening 7 in the housing, in which case the design of the link affects the lever ratio in an analogous manner in an advantageous manner.
  • Fig. 7 it is seen that only upon further movement of the handle 3 and subsequently the lever 6 passes through the safety lock formed by the button 9 away the bolt-shaped projection 12 completely at the end of the backdrop-shaped opening 7 in the housing. In this position, the housing wall thickness is dimensioned so that a withdrawal of the lid 2 and thus its removal is made possible.
  • Fig. 8 and Fig. 9 show in sectional view the arrangement of the large-sized and over the entire height of the product extending guide columns 15a and 15b. These serve on the one hand the easy accurate attachment of the lid 2 after the backup exchange and on the other hand the precise guidance in the guide channels 20a and 20b during the movement operations.
  • the dimensioning of these guide units ensures that the movement of the cover 2 takes place exclusively in the desired direction, even if the resistances are uneven due to tolerance reasons for slightly different contact pressures of the three fuses 26 .
  • the function of the safety mechanism is shown in FIGS. 3, 4 and 9 .
  • the lever 6 has in the region of the handle-side end at least one stop 16 , which in the off position shown in FIG. 3 at one or more Edge 25 of the button 9 strikes. A further movement of the handle is prevented.
  • the button 9 is preferably made in one piece with the handle 3 , wherein a suspension of the button 9 is achieved by a suitable arrangement of exemptions 23 and stiffeners 24 .
  • Fig. 4 the position is at the button is pressed 9. If this against the moved before described spring force in the direction of the lid 2, for example by deliberate pressure with the thumb of the operator, the edge 25 of the button 9 from the area of influence of the lever 6 are attached stops 16 away, whereby the lever 6 can be moved on. By this further movement, the third position shown in Fig. 6 and Fig. 7 is reached.
  • the placement of the button 9 is selected at a convenient location for the operator, however, arranged so that an unintentional actuation of the safety device is prevented.
  • FIGS. 10 and 11 show the handle 3 in a sectional view
  • FIGS. 12 and 13 show an isometric view
  • FIGS. 10 and 12 showing the rest position of the button 9
  • FIGS. 11 and 13 showing the bending of the spring-formed section Elements and the position of the button 9 in the pressed state.
  • a limit 21 of the touch stroke is provided, which is preferably integrally integrated in the handle 3 .
  • FIGS. 10 to 13 furthermore show the bolt 17, which forms the axis of rotation of the handle 3 .
  • holes 13 are provided in the region of the handle 3 and the lever 6 , which are arranged congruently in the closed state. Through these holes, a seal can be done by a conventional seal 5 .
  • tabs can be mounted with further holes 19 in the handle, which are congruent in the closed state with holes 19 in tabs of the lid 2 .
  • these holes 19 conventional padlocks can be attached.
