Definitions
- the invention relates to a switching device with a fixed contact and a movable contact, which together form a contact point form, and with one to delete one on it Arc extinguishing device that serves as the contact point for arcing, the one designed as an arc chamber Assembly of several parallel by means of an insulating strip, spaced extinguishing sheets and a first and comprises a second arc baffle, the two Arc baffles each one of the outer quenching plates are arranged adjacent to the arc quenching device and the insulating strip at the arc chamber end has forming wall on which the quenching plates end.
- Such an arc extinguishing device exists according to the figure 4 often from an arc chamber 1 with arc baffles 2 and 3 and various components, which among other things also perform fluidic tasks.
- the arc chamber 1 is, as shown in FIG. 5, as a U-shaped package punched quenching plates 4, which are arranged in parallel and are kept at a distance.
- a strip of insulating material usually a volcanic fever strip 5, which folded the fire-fighting sheets 4 keeps at a distance and combines into an assembly.
- openings 6 are punched, the under the flow conditions in the arc chamber 1 influence.
- the baffles 2 and 3 are on the top and on arranged lower end of the arc chamber 1 according to Figure 4.
- the upper arc guide plate 2 forms together with a movable Contact bridge 7 a contact point 8.
- FIG. 6 shows a cross-sectional illustration of the arc quenching device the migration of the arc from the Contact point in the arcing chamber.
- the arc baffles are kept relatively short, i.e. not to the end of the arc chamber where the Extinguishing plates end, guided. Another option is completely dispensing with the lower arc guide plate.
- the solution with short baffles has the important one Disadvantage that the entire volume of the inner part of the arc chamber during the extinguishing process optimal is exploited.
- the invention has for its object a switching device to improve the above type in that the arc chamber is optimally used in its extinguishing effect, and at the same time eliminates the danger that the arc shorts in the room behind the arc chamber.
- the object is achieved in that one of the arc baffles beyond the wall of the insulating strip into one Survives behind the arc chamber and at the same time the other of the arc baffles opposite the one behind the arc chamber through the wall of the Insulated strip in connection with a housing wall is. With this configuration, an optimal Efficiency of the arc extinguishing device reached. By the specified partitioning of one of the arc baffles prevents the arc in the room behind the Can short circuit the arc chamber.
- a particularly advantageous embodiment of the invention consists of if one of the arc baffles is supported in this way is that an approximation to the nearest quenching sheet is prevented.
- the support is advantageously carried out on the wall of the Insulating strip. Furthermore, it is advantageous if that over the space behind the arcing chamber Arc baffle except for a mounting game to the Wall of the insulating strip reaches the arc chamber to make optimum use of their extinguishing effects.
- the solution according to the invention does not require any additional parts additional assembly steps.
- an arc extinguishing device is composed of an arc chamber 10 with an upper 11 and a lower Arc guide plate 12 shown.
- the arc chamber 10 is designed as a package made of U-shaped die-cut sheet metal 13, which are arranged in parallel and kept at a distance are.
- the insulating strip 14 has a wall 15 forming the arc chamber closure of the quenching plates 13 end.
- the upper arc baffle 11, which is arranged parallel to the top quenching plate 13, forms a together with a movable contact bridge 16 Contact point 17 at which when the contact opens, i.e.
- an arc forms when the switching device trips.
- Parallel to the lowest quenching plate 13 is the lower arc guide plate 12 arranged that over the wall 15 of the insulating strip 14 into the rear of the arc chamber 10 survives lying space.
- the lower arc baffle 12 is supported on a projecting tab 18 of the wall 15, so that on the one hand an approximation to the closest Extinguishing plate 13 is prevented and on the other hand at the same time Emigration of the arc base at the lower arc baffle 12 in the room located behind the arc chamber 10 is excluded.
- the upper arc guide plate 11 is apart from an assembly game led to a projecting tab 19 of the wall 15. It is in a groove 20 of the housing, of which the housing cutout 21 is shown.
- the upper projecting tab 19 the wall 15, in connection with the housing, creates a partition of the upper arc guide plate 11 compared to the behind the arc chamber 10, which is the above prevents undesirable short-circuiting of the arc.
- Arc quenching device is shown in Figure 2.
- the arc guide plates 11 and 12 have a Arc chamber 10 optimally utilizing length, while at the same time by supporting the lower arc baffle 12 and the partitioning of the upper arc guide plate 11 Danger of a short circuit of the arc behind the arc chamber 10 is turned off. As measures were taken the wall 15 up and down by protruding rags 18 and 19 extended.
- the arc guide plate 12 also down through the housing to be supported so that it is the same as for the upper arc guide plate 11 there is such a partition that the arc base only up to wall 15 of the insulating strip 14 can hike.
- Figure 3 shows the arc chamber 10 with the from the quenching plates 13 existing package through the insulating strip 14 is held together.
- the wall 15 is up and down extended by projecting tabs 18 and 19 as mentioned above.
