Definitions

  • the invention relates to an electrical switching device, in particular a contactor, with at least one contact system which has two contact bridges which are movably held in parallel and at a distance from one another under spring pressure in a contact bridge holder and which cooperate with fixed contact connecting rails, a device with a slide being provided between two end positions can be moved and acts on the contact system such that the contact system forms a closer in one end position and an opener in the other end position.
  • Switchgear of the aforementioned type are required in large numbers in practice. They are used to carry out a wide variety of switching tasks, the switching device in question being actuated either by hand or by machine or by an electromagnet.
  • the switching devices contain at least one contact system, whereby the individual contacts can be designed either as make contacts or as break contacts, depending on which switching task the switching device is to perform, i.e. if the contact in question closes when the device is actuated, it is called a make contact and if a contact opens when the device is actuated, i.e. breaks the circuit, it is called a break contact. Now it happens very often in practice, e.g.
  • a switching device explained at the beginning is already known from document FR-A-2 352 388, and as said, a conversion from a make contact to a break contact and vice versa can be carried out.
  • a rotating body which can be rotated through 180 ° and which, depending on the rotating position, forms different stops for extension parts of the contact bridges.
  • an insulating body is moved against the force of the compression spring in the axial direction between two end positions. In this case too, extension parts of the contact bridges come to different stops and thus optionally to convert from a make contact into a break contact or vice versa.
  • the invention has for its object to provide an electrical switching device that can be made very compact and that requires only a small amount of material for switching from an opener to a closer and vice versa.
  • the displaceable plate is designed so that at least two insulated projections are arranged perpendicular to the plate, which are offset from one another in the stroke direction of the contact bridge holder by the thickness of the contact connecting rails plus the thickness of the fixed contact pieces on both sides, so that the one projection in the one end position of the slide between the one contact bridge and the one contact connection rail and the other projection in the other end position of the slide between the other contact bridge and the other contact connection rail engage in an insulating manner.
  • a further solution to the problem arises from the fact that two contact bridges, which are held parallel and at a distance from one another under spring pressure, are arranged on both sides of the contact connecting rails in a contact bridge holder, and that a middle piece is provided as a device between the contact bridges, such that in the one end position both Contact bridges are held in the raised position and when actuated one contact bridge forms a make contact and that in the other end position the other contact bridge is held in contact position and forms an opener when actuated.
  • the device has a movably mounted body which, on the one hand, contacts the contact acts on the bridge and on the other hand carries a role that interacts with a sliding guide for actuating the switching device, which is designed such that the contact bridge optionally forms a closer or an opener.
  • the main advantages are that the length of the switching device does not go beyond switching devices that have so far been designed without the possibility of switching from normally closed to normally open and vice versa. Furthermore, you can get by with a pair of contact connection rails and the contact bridges can remain symmetrical and small in size.
  • Figures 1 and 2 illustrate a contact system according to the prior art, such as is used as a so-called auxiliary contact in a contactor.
  • the contact system has two fixed contact connecting rails 1 and 2 with contact pieces 3 and 4 and a movable contact bridge 5 with contact pieces 6 and 7.
  • the contact bridge 5 is held in a contact bridge holder 8, which is essentially designed as a double frame and has two openings or windows 9, 10 and two outer webs 11 and 12 and an inner web 13.
  • the contact bridge 5 is inserted in the window 10 and rests on the top of the inner web 13 in the rest position.
  • a contact pressure spring 14 is inserted between contact bridge 5 and web 11.
  • the contact system according to FIG. 1 represents a make contact.
  • the mode of operation is essentially as follows.
  • the contact bridge holder 8 is held in the uppermost rest position by the action of a spring, not shown.
  • the contact bridge holder is connected to a movable armature of a magnet system, the armature also being held in the uppermost rest position by said spring. If the contactor picks up or if it is moved by hand, for example via a push button (not shown) at the upper end of the contact bridge holder in the direction of arrow 15, the contact bridge 5 is carried along until the contact pieces 6, 7 meet the contact pieces 3, 4. The contact bridge holder 8 is then usually moved a little further down, so that the contacts are under the pressure of the contact pressure spring. If one wants to convert this contact system from a closer according to FIG. 1 into an opener according to FIG.
  • FIGS. 3 to 6 show an exemplary embodiment of a switching device according to the invention, in which the conversion from a break contact to a make contact or vice versa can be carried out extremely easily, without any wiring having to be loosened or assembly measures having to be carried out on the contact bridge holder.
  • a device is provided here, in the present exemplary embodiment a slide 21, which can be moved between two end positions. One end position is shown in FIG. 3, the other end position, corresponding to the direction of displacement 24, is shown in FIG. 4.
  • This slide is designed and acts on the contact system in such a way that the contact system has a closer in one end position of the slide and one in the other end position NC contact results.
  • two contact bridges 5 and 16 which are held parallel and at a distance from one another, are arranged on both sides of the contact connection rails 1 and 2 in the contact bridge holder 8 in this exemplary embodiment.
  • the two contact bridges 5 and 16 are under the influence of the contact pressure springs 14 and 25.
  • the contact connecting rails carry contact pieces on both sides, that is to say the contact pieces 3 and 4 on the upper side and the contact pieces 19 and 20 on the underside.
  • the second contact bridge 16 is also provided with contact pieces 17 and 18 equipped.
  • the slide 21 carries two insulated projections 22 and 23, which are arranged such that the one projection 22 in the one end position of the slide 21 according to FIG. 4 between the contact bridge 5 and the contact connecting rail 1 on one side of this contact connecting rail and the other projection 23 in the other end position of the slide 21 according to FIG. 3 engages between the contact bridge 16 and the contact connecting rail 2 on the other side of this contact connecting rail.
  • the principle of operation is as follows. In the position of the slide 21 according to FIG. 3, the passage of current between the contact connection rails 1 and 2 is prevented by the insulated projection 23. If the contact system is now actuated by moving the contact bridge holder 8 in the direction of arrow 15, the contact pieces 6 and 7 of the contact bridge 5 come into contact with the contact pieces 3 and 4, so that a closer is formed. In the other position of the slide according to FIG. 4, the projection 23 is disengaged, so that the contact bridge 16 bears against the contact pieces. In contrast, the insulated projection 22 now engages between the contact pieces 3 and 7. When the contact system is actuated, the contact bridge 16 opens, so that an opener is formed. The contact bridge 5 cannot be switched on again because of the engagement of the insulated projection 22.
  • the slide 21 is advantageously designed as a plate which can be displaced parallel to the two contact bridges 5, 16.
  • the projections 22 and 23 arranged perpendicular to the plate are offset in height approximately by the thickness of the contact connecting rails 1 and 2 and the fixed contact pieces 3, 4 and 19, 20 located thereon.
  • the projections 22, 23 according to FIG. 6 in the direction of displacement of the slide i.e. are each designed inwards to be wedge-shaped or tapered.
  • the plate-shaped slide 21 is longer than the contact bridges 5, 16, the projections 22 and 23 being arranged near the plate ends, so that they come into engagement parallel to the contact bridges 5, 16 when they are pushed in in the direction of arrow 24.
  • the slide can expediently be held on the inside of the wall of a housing 27 shown schematically in FIG. 5 by guide rails (not shown) with stops or similar path-limited guides.
  • the slide 21 is expediently designed and accommodated in the device housing 27 such that it is visible and / or actuatable from the outside. For this you can e.g.
  • the slide 21 is advantageous to provide the slide 21 with labels that are visible from the outside, if possible, which, depending on the position, indicate whether the contact system is effective as a closer or opener.
  • the designations can, for example, be designed according to the European standard.
  • the slider 21 and / or the projections 22, 23 are formed from insulating material. It is advantageous to make the protrusions, but possibly also the slide, from arc-proof material.
  • locking devices are expediently provided with respect to the two end positions of the slide.
  • This can e.g. Be leaf springs that engage in notches of the slide.
  • FIGS. 7 to 9 illustrate a further exemplary embodiment of a switching device according to the invention, which essentially corresponds to that according to FIGS. 3 to 6, so that the explanations there also apply mutatis mutandis to this exemplary embodiment, the same reference numerals being used for the same parts .
  • the slide 21 is provided with two pairs of projections 22, 23 and 29, 30 for the alternating engagement between the contact bridges 5, 16 and the contact connecting rails 1, 2 at both ends of the contact bridges.
  • the projections engage at both ends of the bridge in question and prevent the passage of the electrical current.
  • the current passage between the contact connecting rails 1, 2 and the contact bridge 16 is interrupted.
  • a contact system according to the prior art will be explained with reference to FIGS. 10 and 11. It is then known per se to arrange two contact bridges 5 and 16 in a contact bridge holder 8 on both sides of the contact connecting rails 1, 2. When actuated, the contact bridge 16 first opens, after which the contact bridge 5 then closes again. It is therefore only a question of a special switching operation, namely when the contact bridge holder 8 is actuated or pressed down once, the contact is first opened and then immediately closed again. There can be no question of converting make contact into break contact or vice versa.
  • FIGS. 12 to 17 illustrate a further exemplary embodiment of a switching device according to the invention, the same reference numerals having been used for the same or equivalent parts as in the previously explained exemplary embodiments.
  • the inner web 13 of the contact bridge holder 8 explained above has been at least partially omitted.
  • a middle piece 31 is arranged between the contact bridges 5 and 16, which is movable between two end positions, such that in the one end position according to FIGS. 12 and 13 both contact bridges 5, 16 are held in the raised position and, when actuated, the one contact bridge 5 forms a closer and that in the other end position according to FIG. 14 the other contact bridge 16 is held in contact position and forms an opener when actuated.
  • the center piece 31 is advantageously designed as a rectangular piece with rounded corners and is pivotably mounted about an axis 32 which is offset from the center.
  • the contact system offers a closer and according to FIGS. 14 and 15 an opener.
  • the conversion from make contact to break contact is carried out in a simple manner by rotating the rectangular center piece 31 from the position shown in FIG. 12 clockwise through 90 ° about the axis 32.
  • the axis 32 is mounted perpendicular to the common center plane of the contact bridges 5, 16 in the contact bridge holder 8.
  • the axis is advantageously accessible from the outside at least at one end, i.e. according to FIGS. 13 or 15, it can be extended up to the outer surfaces of the contact bridge holder 8.
  • Notches 33 can be provided on one or both ends of the axis 32, which can be engaged, for example, by means of a screwdriver and the change can be made.
  • the axis 32 can also be extended so far that it extends to an opening in the housing wall of the device or protrudes through the opening, so that the described changeover can be carried out from outside the device without any assembly work.
  • a plunger 26 or a push button for manual actuation or for mechanical actuation can be connected to the upper end of the contact bridge holder 8, as can be seen in the housing wall or through an opening in the cover of the housing protrudes.
  • Figures 18 to 22 illustrate a further embodiment of the switching device.
  • a contact pressure spring 14 which is under the pressure of a contact pressure spring 14, this contact pressure spring 14 being supported on any abutment 34.
  • the device has a movably mounted body 35 which acts on the one hand on the contact bridge 5 and on the other hand carries a roller 44 which interacts with a cam guide which can be displaced to actuate the switching device and which is designed such that the Contact bridge 5 optionally forms a closer or an opener.
  • the curve guide consists of two guide parts 45 and 46 running alongside one another.
  • the body 35 has a shaft 36, on the one end of which, in the lower drawing, ends, pins 38 and 39 are provided on both sides, which are held removably in a pivot bearing 40 .
  • the pivot bearing 40 can for example be semi-cylindrical.
  • a hammer head 37 or a hammer-head-like extension is provided, on which, at a distance from one another, bearing pins 41 and 42 for the optional attachment of the roller 44 are mounted on one side parallel to the pins 38 and 39.
  • the roller 44 is therefore attached to the body 35 so that it can be placed against one or the other guide part 45 or 46.
  • the guide parts 45 and 46 have mutually offset depressions 48 and 50 as well as projections 47 and 49.
  • This design of the two guide parts makes the contact bridge 5 by pressing the contact pressure spring 14 in the direction of the contact connecting rails 1, 2 when the roller runs on the one guide part 46 moved because the roller 44 hits the recess 50 (FIG. 19) from the projection 49 via the inclined surface 52 as soon as the guide part 46 moves downward in the direction of the arrow 51, that is to say the switching device is actuated.
  • the body 35 is expediently provided in the extension of its shaft 36 with a handle 43, on which at the same time an inscription visible from the outside can be applied, which indicates whether the contact system forms a closer or an opener. In order to convert the contact system from the closer described into an opener, one only needs to detach the body 35 from the pivot bearing 40.
  • the roller 44 is pushed from the bearing journal 41 onto the other bearing journal 42. If you now pivot the body 35 in the direction of arrow 54 about the longitudinal axis of the shaft 36 by 180 ° and then, as described, reinsert the body into the pivot bearing, the roller 44 rests on the guide part 45, in the rest position now of the recess 48. If you now guide the guide member 45 in the direction of arrow 51 when actuating the switching device down, the roller 44 runs from the recess 48 over the inclined surface 53 on the projection 47, whereby in this case the body 35 is pivoted such that the entrained Contact bridge 5 lifts off and thus an opener is formed. In the representation according to FIGS. 18 to 21, the contact system thus forms a closer, while an opener is formed after the changeover according to FIG.
  • FIGS. 24 to 28 finally illustrate a further exemplary embodiment of a switching device according to the invention, the effect of which essentially corresponds to that of FIGS. 18 to 22, so that the explanations there apply analogously.
  • the head piece 56 is designed to project only on one side of the body 35, which in turn interacts with the contact bridge 5.
  • an axle bearing 57 is provided for the axle 55 of the roller 44, which in turn runs in a fork-shaped recess 58.
  • only a single component 60 is provided as a guide, which is detachably attached to an actuator (not shown) and can be pivoted through 180 °.
  • the component 60 has at least one projection 61 and a depression 62, such that the projection 61 and depression 62 are exchanged in their position relative to the roller 44 when pivoted through 180 °.
  • roller 44 runs from projection 61 over inclined surface 63 and thus swivels together with body 35 and head piece 56 in the direction of Arrow 59, so that the contact bridge 5, which is under pressure from the contact pressure spring 14, can go along and thus form a closer.
  • Figures 26 to 28 illustrate a practical embodiment of a component 60 with two lateral guide ribs 67 and 68, which are used for insertion into a guide of the actuator of the switching device.
  • a projection 69 can be provided on the rear side, which comes into a recess in the actuating member and thus prevents unintentional displacement.
