CONNECTING SYSTEM WITH AN ELECTROMAGNETIC SWITCHGEAR, IN PARTICULAR CONTACTOR, AND A PLUG

Description

Connecting system with an electromagnetic switchgear, in particular contactor, and a plug

The invention concerns a connecting system with an electromagnetic switchgear, in particular contactor, and a plug.

For the control a contactor must be set on the contactor drive unit a tension. For this it is well-known to firmly plan at least two coil connecting terminals attached at the contactor housing. Since contactors can be combined in different way with other switchgears, these coil connecting terminals are frequently covered, so that they are intended again partly in other places of the contactor housing. In particular if the coil connecting terminals beside the connecting terminals for the main circuit or auxiliary conducting path are arranged, so that the coil connection borrowed from the front zugäng is, at least one coil connecting terminal is more badly accessible with a combination with other switchgears. This is in particular then a problem, if lines with large diameter are intended, around larger achievements too scolded. Beside these devices, with those the coil on conclusion-wedges in a connection area with the main and

Auxiliary leader clamps lie, are well-known switchgears, with de¬ nen the coil connecting terminals under the main leader clamps are arranged. With such switchgears the accesibility is again due to the still more complex structure he sword, if the main leader is attached. With a cultivation of additional switchgears, for example a Leis¬ tungsschalters and/or an overload relay, the Spu¬ is not lenanschlüsse in these cases any more zugäng¬ lich.

Besides the task exists to attach the drives and auxiliary switches with the control and the electrical bolting device of contactors and/or switchgear combinations (for example reversing contactor combinations, star triangle contactor combinations, circuit-breaker contactor combinations). Usually this happens with insulating lines, which are attached to the connecting terminals planned for it. Problema table with this connection technology is however the time-consuming and possibly faulted wiring of the switchgears.

The DE 89 0 0361 Ul reveals electromagnetic equipment, whose auxiliary switch and coil connections are in one level. The auxiliary switch connection are taktierbar with a plug kon.

A task of the invention is it to facilitate an attaching of auxiliary and control lines with electromagnetic switchgears.

This task is solved by an electromagnetic switchgear according to requirement 1. Afterwards the connecting system exhibits at least an electromagnetic switchgear and a Ste¬ more cker. With the fact it is substantial that the plug is trained as the simultaneous contacting of in one level lying reeling and auxiliary switch connection at least a Schaltgerä¬ of the tes, whereby the plug exhibits an internal Verdrah tung for electrical connection the reeling and/or auxiliary switch connection among themselves. Thus on the one hand the connection and thus the handling of the Schaltgerä¬ of tes are substantially simplified, since the coil connections are substantially better accessible made available unabhän¬ gig by different superstructures and connection technologies flexi with and the solutions well-known compared with. On the other hand according to invention needed for the realization of different Anschlussfunkti¬ onen only in each case another plug. A aufwändige and error-prone manual wiring of the auxiliary and control lines is void. Attaching can be accomplished with the help of the before-wired plug substantially faster and faultlessly. The invention is suitable from there beson¬ ders well for the use with switchgear combinations without SPS control, which put very often additional aufge¬ front-lateral auxiliary switch blocks needs.

Favourable execution forms of the invention are in the Un teransprüchen indicated.

Thereafter an arrangement of the Spulenan¬ of conclusion at the front of the switchgear is particularly favourable. Coil on to conclusion-wedge knows then universally in such a manner arranged who that an accesibility is by the plug from above, from downside and from the front realizable, without coil on conclusion-wedges at several different places be planned must. Thus the structure is not only simplified by Schaltge¬ advice highly. Also the management a that acre of a tigen switchgear is substantially improved, since an on conclusion is from the front possible. With the use one from the front electrically and coil connection mechanically plug-in of klemmenblocks is reached thereby a particularly simple handling. The coil connecting terminal block is connected by manufacturing only one plug connector not only mechanically, but also electrically with the switchgear. Aufwändige auxiliary connections are void.

It is particularly favourable, if the Spulenanschlussklem menblock and/or the auxiliary switch blocks as integrated

Construction units are trained in the plug. The coil connection and/or the connection of the auxiliary switches can take place thereby via simply plug-on of the plug to the front of the Schalt¬ of equipment, without intermediate elements must be inserted in the form of SE ready blocks, which simplifies the handling clearly again.

The invention in the following described on the basis of Ausführungsbeispie¬ len, which are tert with the help of the designs more near erläu. Here show:

FIG 1 shows one from the state of the art admitted contactor 101, which is upward represented with its back 102 downward and with sei¬ ner front 103. On the Vor¬ that side 103 the contactor the 101 is toward the contactor upper page 104 an upper connection row 105 and toward the contactor lower surface 106 a lower connection row 107 vorgese¬ hen. The two connection rows 105, 107 cover thereby in each case three main terminals 108, an auxiliary switch on conclusion 109 and a coil connection 110. The upper connection row 105 and the lower connection row 107 lie in one level. Main stream, auxiliary switch and coil connection 108, 109, 110 are designed as screw connections. The o bere connection row serves 105 thereby as input and the lower connection row 107 as outlet side.

With the contactor 111, which likewise admits from the state of the art is, shown in FIG 2, are on the same Bau¬ broad, as them that contactor 101 from FIG 1 exhibit, in place of five only in each case three connections intended, so that grö¬ ßere cross sections for connection scolded to by higher rivers be used can. Since the main terminals 108 take the entire building width the contactor the 111, 111 four photographs 112 for additional auxiliary switches (not illustrated) are intended on the Vor¬ that side 103 the contactor. Auxiliary scarf more ter can be attached however also laterally at the recesses 113 of the contactor housing for this planned. For the connection of the coils 106 and at the contactor top side 104 in each case two coil connections 114 are intended at the contactor lower surface, which are leading connected diagonally by the contactor housing with one another. Now for example sol¬ cher contactor 111 at its lower surface 106 or its upper egg if a Te 104 is connected with a further switchgear or such a thing, then individual coil connections are 114 completely covered in such a manner that either coil entrance or Spulenaus¬ course cannot be contacted any longer.

Contrary to these from the state of the art solutions admitted an optimal accesibility made possible with a switchgear according to invention the coil connecting terminal block with any structure way of the switchgear to the clamps of the coil connection and prevent with the fact that wires must be led across other switchgears.

Clamps with different connection technologies, for example cage tension spring etc., at the switchgear can be put for screw connection, gumption clamp, Push in technology. If it concerns with the switchgear a contactor, with which for example the main leader clamps are implemented in screwing technology, all possible connection variants can, including which auxiliary and tax leaders are put. The switchgear is in other words preparatory for a plug-in connection with auxiliary and tax leaders.

With the help of the invention it is possible to reduce the number of en for ski those necessary designs with switchgears. Even if the switchgears plan different An¬ conclusion techniques with the tax clamps, they can be combined with the help of the invention among themselves. Due to the plug connector an exchange of the coil on of conclusion wedging block and thus a change of the Anschluss¬ technology are easily and way possible and can also by the user be implemented.

Preferably the Spulenanschlussklem from the front plug-in is intended menblock as exclusive coil connection. Further one

Coil connections toward the upper connection side bezie¬ hungsweise toward the lower connection side of the Schalt¬ of equipment are in other words intended. Thus the constructional structure of the switchgear becomes strongly association kindles, without the functionality of the switchgear suffers darun¬ more ter. Of course it is likewise possible to use the coil connecting terminal block according to invention as addition of existing stationary coil connecting terminals.

It is particularly favourable, if the coil connecting terminals are one above the other arranged in stages. Thereby different contacting levels can be defined.

A coil connecting terminal block also in stages one above the other arranged coil connecting terminals can be preferably turned in its connection direction. The coil connecting terminal block is then depending upon arrangement at the switchgear both from downside and from above contactable. In other words it is for example possible to begin for the coil connecting terminal block with its stage lain more highly toward the upper connection side or toward the lower connection side of the switchgear. Thereby the universal applicableness coil connecting terminal according to invention of the block is again improved. Depending on, which are desired Gerätekombina¬ tionen or connection variants, the different connection areas can be aligned upward or down.

FIG 3 to 6 show coil connecting terminal according to invention of blocks 1, 2, 3, 4. the coil connection klemmenblock 1 represented in FIG 3 exhibit two coil connecting terminals 5, 6, which are gradate-like arranged in two connection areas 7, 8 arranged one above the other. At its lower surface 9 the coil connecting terminal block 1 exhibits two plug contacts 10 in the form of contact pins. These serve the simultaneous mechanical and electrical putting contacting of the coil on of conclusion wedging block 1 with a contactor according to invention. The coil connecting terminals 5, 6 can with compression joints and/or plug connectors and/or bolt connections (FIG 6) to be implemented. The arrangement of feather/spring course clamps (FIG 5) is alternative possible. In the simplest case the plug contacts 10 at the lower surface 9 of the Spulenanschlussklem are upward extended menblocks 2 and rise up as entspre¬ chende connection plug contacts 11 out of the top side 12 of the coil connecting terminal block 2 outside (FIG 4). Selbstver¬ ständlich is likewise possible it that more than two Spu¬ lenanschlussklemmen in a coil connecting terminal block 3, 4 are integrated. Like that it is for example possible that je¬ weils two connection contacts are input and outlet-laterally intended (FIG 5 and 6). In variation with arbitrary gradations for the education of different connection areas 7, 8 arises as a result of it a multiplicity of connection variants. The connection directions are represented in FIG 3 to 6 by arrows A. An alternative connection type in FIG 3 shows arrow A'.

In FIG 7 is shown an example contactor according to invention 15. Beside already from FIG the 2 three in admitted 16 three Hauptstromanschlüs¬ to course-lateral outlet-lateral in an upper connection row 17 and main terminals sen 18 in a lower connection row 19 and three photographs 20 for additional auxiliary switches (not illustrated), is intended at the front 21 the contactor 15 an additional Steckerauf¬ nahme 22 to the training of a plug connector. The admission 22 points thereby 23 to the Aufnah ME of the plug contacts 10 of a coil connecting terminal block 1, 2, 3, 4 to two photograph openings to in such a manner that with a put in coil on conclusion wedging block 1, 2, 3, 4 exist its plug contacts 10 in an electrical connection with the coil connections 24 at the contactor top side 25 on the one hand and the contactor lower surface 26 on the other hand. This connection can be created for example by a plate 27, a wire or such a thing by the plug admission 22 to the coil.

FIG 8 shows the contactor 15 from FIG 7 with put on reeling connecting terminal block 1. the coil connecting terminal block 1 with its plug contacts 10 and the plug admission 22 at the front 21 the contactor the 15 is in such a manner ausgebil¬ det with the fact that the coil connecting terminal block 1 with its stage 8 lain more highly can be used toward the upper connection row 17 (as shown). Thus are the Spu lenanschlussklemmen 5, 6 from downside (arrow A) accessible. Beyond that it is just as possible, the coil connecting terminals 5, 6 with the mounting method from above, shown in FIG 8, to attach (arrow B).

Alternatively to it however the coil connecting terminal block 1 with its stage 8 lain more highly knows (turned around 180°) toward the lower connection row 19 the contactor the 15 einge¬ also sets to become. Thus it is guaranteed that the coil on conclusion-wedges 5, 6 also from above (arrow B) is accessible. Beyond that it is just as possible, the Spulenanschluss¬ wedges 5, 6 with this mounting method from downside close (arrow A) anzu¬. Due to the many connection variants a multiplicity of application type results for the coil connecting terminal block.

At the same time the coil connecting terminal block 1 lifts few individual coil connecting terminals 6 into the level of the connection wedges 30 installed front-lateral auxiliary switch blocks 31, as it is exemplarily in FIG 9 shown. In this case the input, upper connecting terminals 30 of the front-lateral auxiliary switch blocks 31 can be contacted together with, the upper connection area 8 of the Spulenanschlussklem lain more highly menblocks 1 over a common plug (not illustrated), which facilitates the accesibility.

In FIG 10 a further execution form of the invention is posed, with which again three auxiliary switch blocks 32 and a coil connecting terminal block 2 on the front 21 are put for the contactor the 15 next to each other. All contacts 10, 11 participate as plug contacts trained such, how this with the coil connecting terminal shown in FIG 4 2 the case blocks is. Since all contacts 11 besides in a common connection area 33 lie, a contacting of all connections including auxiliary and control ports is from the front possible with the help of a common plug 34. The plug 34 points thereby an internal wiring to (not illustrated) for the electrical connection of the reeling and/or auxiliary switch connections among themselves. Thus are a fast, a simple and an error-proof brought together from lines to superordinate controllers like e.g. Tracer, signalling equipment, SPS etc. possible. Besides can lines, which serve for bolting devices or connection of the contacted devices (e.g. for grinding through for a zero-leader for the coil connection or for a connection of the opener first contactor to a Spulenklemme second contactor with a reversing contactor combination) by the internal wiring of the plug are replaced. The plug 34 is provided with a connecting cable 40 for connection with a superordinate tax module or such a thing.

Of course it is possible to contact such contactors 15 with egg for nem plug 34 the blocks with other connection types exhibits. For example a contactor 15 from the front with a plug 34 could be contacted, the blocks 3 exhibits with connections as represented in FIG 5. Even if is possible a plug 34, which does not make a contacting from the front, but the blocks in one seitli¬ chen contacting direction attach, so that also blocks 1, 4 can be used with connections, as they are shown into the FIG 3 and 6.

FIG 11 illustrates the connection of two contactors 15, 15 ' with the help of only one plug 41. Each contactor 15, 15 ' points again three auxiliary switch blocks 32 (normally open contact, opener, normally open contact) and a coil connecting terminal block 2 next to each other to (in this order), so that a kind Wende¬ combination results. All eight blocks 2, 32 are from the front contacted at the same time with the plug 41. The plug 41 exhibits an integrated wiring in form of a Verdrah tungsbausteins, whereby both an auxiliary leader wiring and a main circuit wiring (coil wiring) take place. As on the plug top side by markings 42 suggested, the plug shown 41 connects on the one hand the upper coil connection to first contactor 15 with the upper coil connection second contactor 15 ' and on the other hand so¬ probably the lower coil connection first contactor 15 with the lower opener connection second contactor 15 ' and the lower opener connection first contactor 15 with the lower coil connection second contactor 15 '. In other words take place with the contactor turning combination shown via the plug 41 a connection of the two Spulenklemmen a2, the mutual electrical bolting device (by the connection from coil connection Al first contactor 15 with the opener second contactor 15 ' and the connection of coil connection of the Al second contactor 15 ' with the opener first contactor 15) and the coupling to a control system (e.g. tracer or SPS) via a flat strip cable 43. That means that by er¬ would not preferably only find-in accordance with-eat plug 41 a connection of the contacted contactors 15, 15 ' among themselves, son dern also a binding of the contactors to a bus system. Alternatively to the flat strip cable 43 also a connection can take place to a superordinate control system with the help of a two-wire communication. As represented in FIG 11, a reduction takes place from An¬ conclusion lines thus via internal linkages. These linkages can follow for example also over logic components he, so that also certainly over a simple electrical Kontak tierung handing out connections can be created to the implementation (scolding) functionalities. In other words also a signal processing and/or a signal preprocessing can take place in the plug 41.

That the two contactors 15, 15 ' together contacting Ste¬ more cker 41 can be einstückig trained. Regarding the manufacture and stock program costs it is of advantage however, if only a kind is intended by plug. That the two contactors of 15, 15 ' together contacting plugs 41 is compound up from there preferably from two smaller plugs 34.

FIG 12 shows a schematic representation of a combination of a circuit-breaker 36 and a according to invention

Contactor 15. That contactor 15 is arranged thereby below the Leistungs¬ of switch 36 and connected with this. In other words the circuit-breaker 36 borders on those, top side 25 the contactor the 15. So that is freely accessible to Handbedienteil 37 of the achievement of switch 36 and not of lines ver¬ covers becomes, is from downside, thus necessary from direction of its lower surface 26, a connection the contactor the 15. Here a front-lateral auxiliary switch block (not illustrated) with the connecting terminals is used downward. The coil on conclusion wedging block 1 becomes in such a way on the front 21 of the

Contactor 15 touched down that the connecting terminals 5, 6 show downward. In other words all auxiliary lines (not illustrated) become to the contactor 15 from downside at these herange¬ lead, since the upper input the contactor 15 of the circuit-breaker 36 nachbarten because of cannot be used. The connection direction is represented by arrow A. In FIG 13 is shown a schematic representation of a combination a contactor 15 with an overload relay 39. The overload relay 39 is arranged thereby mechanically outlet-laterally, thus at the lower surface 26 the contactor the 15. The coil on conclusion wedging block 1 is with its connection stage 7 lain more deeply toward the contactor top side 25, thus in course-laterally, arranged. From there it is contacted over a wire (not illustrated). In other words auxiliary leaders and coil are attached from above. Frontseiti the ge auxiliary switch block (not illustrated) is used upward with an¬ to conclusion-wedge. The Spulenanschlussklem menblock 1 is thus in such a manner turned that the connecting terminals 5, 6 show upward, so that all auxiliary lines are attached to the contactor 15 from above. The connection direction is represented by arrow A.

FIG 14 shows finally a schematic representation of a combination of circuit-breaker 36, contactor 15 and overload relay 39. With this combination the coil connections are covered both above and down with most knew contactors. By the employment of the Spu according to invention lenanschlussklemmenblocks 1 the accesibility of the Spu¬ lenanschlüsse is protected. The front-lateral auxiliary switch block (not illustrated) is used downward with the connecting terminals. The coil connecting terminal block 1 is turned likewise in such a way that the connecting terminals 5, 6 to show downward, so that all auxiliary lines are from downside attached to the contactor 15. The Handbedienteil 37 of the Leistungsschal¬ ters 36 remains free thus. With the available invention a simple contacting barness becomes at all only possible with this combination. Beyond that one results vari¬ abel selectable wiring over only one equipment, whereby preferably a wiring selects over the overload relay 36 ge¬ becomes. The connection direction is by arrow A darge places.

FIG 15 illustrates a schematic representation of a contactor turning combination, thus a combination of a Leis tungsschalters 36 and contactor according to invention 15, as she is represented already in FIG 12. In contrast to FIG 12 on the contactor however beside a coil connection also the auxiliary switch blocks 32 are attached klemmenblock 3. Are the coil connection the coil connection of the klemmenblocks 3 in one level 8 with the auxiliary switch on conclusions 30. All connections in this level 8 are contacted with the help of a common plug 34.

At the input of the circuit-breaker 26 the Ein¬ feeding system 44 is shown, with whose assistance a main leader is attached at the circuit-breaker 36. For the connection the contactor the 15 to the main circuit serves a nes contacting element 45 angeschlosse on the opposite outlet side the circuit-breaker 36, which connects the line switch 36 with the contactor 15. Outlet-laterally the Hauptlei¬ leaves tung 46 then the contactor 15 again.

Beyond that an auxiliary switch 47 is intended at the circuit-breaker 36, over which the switching status of the Leistungsschal¬ is passed on ters 36 to the plug 34. For this purpose the auxiliary switch 47 connected with the plug 34 by a signal line 48 is. The plug 34 exhibits beyond that a flat strip cable 43, the which for the connection the contactor serves 15 to a bus system and which plug 34 leaves outlet-laterally. With other words, with the plug 34 the single connections are summarized and bundled and passed on to the Flach¬ ribbon cable 43, which connects the combination with a superordinate tax place.

Contrary to FIG 15, where the auxiliary switch 47 over lines 48 to the plug 34 is coupled, FIG 16 shows an execution of a system, with the circuit-breaker 36 and contactor 15 with the help of a complete plug 50 is connected. Into this complete plug 50 only the coil connecting terminal block is not integrated. It contains in addition also the appropriate auxiliary switch blocks 32 so that it for a direct contacting with the front 21 the contactor the 15 is trained. In other words the plug contacts of this complete plug 50 directly with appropriate plug photographs 20, 22 on the front 21 are connected the contactor the 15. In the complete plug 50 also that is the Leis more tungsschalter assigned auxiliary switch 47 ' integrated.

The complete plug 50 serves beyond that for the connection the protection turning combination to a component arranged between line switch 36 and contactor 15 for the collection and Auswer tung the river in the lines, e.g. an overload relay 51, as well as to an overload protection 52. The overload protection 52 is arranged from assembly view behind the circuit-breaker 36, sozusa¬ towards in the building depth of the combination, so that front¬ place for the complete plug 50 remains laterally sufficient to the en adding. The overall height of the combination is however not increased by this arrangement.

Finally contain the plug 50 also sensors, those the switching status of circuit-breaker 36 and contactor 15 abfra towards. In addition the contactor coil and the current evaluation component 51 are contacted, linked and summarized the connections entwe¬ that central or connected by a Kommunikations¬ interface with the control. Thus the complete plug 50 measures all functions of the combination (Mo torabzweig), then to a central control unit, bei¬ a spielsweise SPS, to be passed on.

As a result of the available invention thus summarized the following advantages arise: Integration of several auxiliary switches into the plug system, application with most different contactors and sizes (equivalent auxiliary switch and Spu lenanschlussblock for the contactors), optional integration of different circuit-breakers by their auxiliary scarf more ter as well as use of an identical interface (ouple places front-lateral auxiliary switch), whereby the interface for most contactors is size-spreading alike. A nuclear thought of the available invention consists of the fact that with the help of a plug both the front-lateral auxiliary switches and the coil connecting terminals is contacted directly at the same time. Thus can be seized substantially more auxiliary switch per equipment, and this with different contactors.
