Definitions
- the invention relates to a contact arrangement for an electromagnetic switching device with multiple interruption with movable contact pieces, the spring-loaded in a contact actuating element are feasible and are fixed by a spring plate.
- An electromagnetic switching device includes a magnetic coil which is fixedly fixed in the switching device and a magnetic coil driven by the magnetic yoke and armature, wherein the yoke is also fixedly disposed in the housing or relative to the magnetic coil and the armature is movable.
- the armature is connected to a contact carrier, which carries movable contacts, which are brought in turn in the closed state of the switching device with housing fixed fixed contacts in touch.
- the switching device also contains, among other springs or spring plate. All components of the electromagnetic switching device must be arranged with respect to their geometric arrangement to each other clearly over the lifetime mechanically and electrically reliable.
- a switching device is known in which the separate contact bridges are additionally provided in their center with defined contact points, which rest on a standing under the action of a common contact pressure spring pressure plate made of highly conductive material, so that the two contact bridges electrically connected to each other.
- a conical contact stud and on the other contact bridge two contact studs are present.
- the contact bridges are freely movable relative to the pressure plate, so that the contact bridges can tilt in any direction during the movement of the contact bridge carrier, in particular during the switching process.
- displacements of the contact bridges in the holder not exclude, which occurs in particular during assembly, since no special guide means are provided for the bridge.
- DE 22 53 918 C3 describes a contact arrangement for a switching device with multiple interruption by parallel contact contact points of two in a contact actuator via a spring plate for the contact pressure spring guided contact bridges, wherein the spring plate transversely to the suspension direction has incisions into which the contact bridges with the spring plate locked are inserted transversely to its longitudinal direction.
- Switching devices consisting of a held in a contact bridge carrier via a guided against displacement transverse to the direction of movement spring plate, against the force of a contact pressure spring in the direction of movement with the spring plate displaced, cranked contact bridge, which can be brought into contact with fixed contact parts via contact pads, wherein the contact bridge in the longitudinal direction is divided into two parts and in the region of the bend is narrower on both sides than the maximum width is executed.
- the known from the prior art embodiments for a contact arrangement of an electromagnetic switching device have the disadvantage that the switching pieces are designed with multiple interruption cranked to prevent the shifting of the contact pieces in the contact operation. With the cranked design of the switching pieces a larger space is required to achieve the freedom of overlap from NC to NO contact. In addition, a high installation effort is associated with the intermeshing of the contact pieces.
- the object of the present invention is to provide a contact arrangement for an electromagnetic switching device with multiple interruption create, which allows a compact, space-saving positioning of the contact pieces and also minimizes the assembly effort.
- This object is achieved by a contact arrangement with the features of patent claim 1.
- Advantageous embodiments and developments, which can be used individually or in combination with each other, are the subject of the dependent claims.
- electromechanical switchgear such as contactors or motor starters
- the contact arrangement of the movable contact pieces with multiple interruption is realized by means of movable switching pieces connected in parallel, which are preferably fixed in the center and guided in an error-loaded manner in a contact actuating part.
- the storage of the contact pieces in the spring plate is designed so that it withstands high shock loads. This is achieved by a finger-like projection on the contact piece, which is preferably close to the switching piece center to increase the support in the bearing.
- this effect is exacerbated by the fact that this finger-like projection engages in the spring plate and thereby prevents a displacement of the contact pieces.
- This extension on the movable contact piece is dimensioned so that only one contact piece design per flow path is required.
- material extensions are attached to the spring plate for this purpose, which should guide the switching pieces safely in the bearing.
- the contact arrangement according to the invention thus has the overall advantages that a smaller space requirement in the switching part is required, since by the chosen construction no cranking of the switching pieces is required, and that the assembly is characterized in that the switching pieces do not have to be mounted in each other, is much easier to carry out.
- the spring plate is also dimensioned so that it can be used as a spring plate for fixing the movable contact pieces as spring bearings.
- the spring plate is structurally designed so that the two parallel movable sections are galvanically separated from each other.
- the spring plate is provided with at least one notch, in which engage the finger-like extensions of the switching pieces to thereby fix the switching pieces more effectively in the bearing.
- the spring plate can be structurally designed so that it can be used both for supporting the spring in the contact actuating part, as well as for the storage of the two movable contact pieces.
- FIG. 1 shows a perspective view of two switching pieces according to the invention
- FIG. 2 is a sectional view of the switching pieces according to the invention according to FIG. 1 integrated into an electromagnetic switching device;
- FIG. FIG. 3 is a perspective view of the switching pieces according to FIG. 2 integrated into an electromagnetic switching device;
- FIG. 5 is a perspective view of the spring-loaded contact arrangement with spring plate and contact pieces
- FIG. 6 is a perspective view of the spring-loaded contact arrangement with spring plate and contact pieces of FIG .. 5
- the 1 shows two switching pieces 1, 2 which are preferably arranged parallel to one another and which preferably each have a finger-like extension 3, 4 centrally in the region of the respective switching piece center of gravity.
- the finger-like extensions 3, 4 are rectilinear, that is, not cranked, executed and are located in the gap between the two mutually parallel switching pieces 1, 2.
- two opposing finger-like projections 5, 6 are arranged, which from the underside to Switching device arranged Fe- derteller 15 emerge.
- the contact pieces 1, 2 are web-shaped and have contact elements 7, 8, 9, 10 at their respective ends.
- the contact pieces 1, 2 the finger-like projections 3, 4 opposite recesses 11, 12, in which installed in the switching device state guide rails protrude.
- the switching pieces 1, 2 are preferably galvanically separated from each other.
- Fig. 2 the switching pieces 1, 2 according to the invention are shown within the usual environment of an electromagnetic switching device.
- serving as guide rails 13, 14 housing projections are visible, which protrude into the recesses 11, 12.
- Fig. 3 shows the mutually parallel switching pieces 1, 2 with the finger-like projections 3, 4 and the protruding from the spring plate 15 finger-like projections 5, 6 within a contact actuating element sixteenth
- Fig. 4 the loaded by a spring 17 contact arrangement according to the invention is shown, wherein the spring 17 acts on the spring plate 15 which holds the switching pieces 1, 2 in a predetermined storage by the finger-like projections 5, 6.
- FIGS. 5 and 6 respectively show the spring-loaded contact arrangement according to the invention with spring plate 15 and the contact pieces 1, 2.
- the contact arrangement according to the invention for electromagnetic switching devices with multiple interruption enables the reduction of assembly work, since the switching pieces are rectilinear, that is, non-cranked, executed, and therefore do not need to be plugged into each other, as well as a compact, space-saving use of space.
