Elektrizitätszähler mit einem Gehäuse, einer elektrischen Klemmenanordnung und einer LeiterplatteElectricity meter with a housing, an electrical terminal arrangement and a circuit board
Die Erfindung betrifft einen Elektrizitätszähler gemäß den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to an electricity meter according to the features of the preamble of patent claim 1.
Derartige zum Stand der Technik gehörende Elektrizitätszähler sind z.B. aus G 93 18 942.7 bekannt. Die bekannten Elektrizitätszähler weisen eine Grundplatte und einen Klemmenblock auf, in welchem Kammern zur Aufnahme der Klemmen angeordnet sind. Die Klemmen werden dabei größtenteils einzeln in den Klemmenblock eingelegt und anschließend mit der Leiterplatte mit teilweise erheblichen Verdrahtungs- bzw. Verlötungsauf- wand verbunden.Such prior art electricity meters are e.g. known from G 93 18 942.7. The known electricity meters have a base plate and a terminal block, in which chambers for receiving the terminals are arranged. For the most part, the terminals are individually inserted into the terminal block and then connected to the printed circuit board with sometimes considerable wiring or soldering work.
Beim Einsatz derartiger Elektrizitätszähler kann es bei der Montage bzw. Demontage/Reparatur zur Beschädigung des Klem- menbereichs kommen. Die Klemmen sind in einem solchen Falle auszutauschen, was mit einem nicht unerheblichen Verdrahtungs- und Arbeitsaufwand verbunden ist.If such electricity meters are used, the terminal area may be damaged during assembly or disassembly / repair. In such a case, the terminals must be replaced, which involves a considerable amount of wiring and work.
Der Erfindung liegt die Aufgabe zugrunde, einen Elektrizi- tätszähler mit den Merkmalen des Oberbegriffs des Anspruchs 1 derart weiterzubilden, daß die Montage bzw. Demontage solcher Zähler vereinfacht wird.The invention has for its object to develop an electricity meter with the features of the preamble of claim 1 such that the assembly or disassembly of such meters is simplified.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Pa- tentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen 2 bis 19.This object is achieved by the characterizing features of patent claim 1. Advantageous developments of the invention result from subclaims 2 to 19.
Als Kern der Erfindung wird es angesehen, daß der Klemmenblock unabhängig von den Klemmen lösbar ist und ein Teil der Klemmen, nämlich die Spannungs- und gegebenenfalls Zusatzklemmen unmittelbar auf der Leiterplatte befestigt sind. Durch diese Anordnung können die Klemmen automatisch von einem Bestückungsautomaten auf die Leiterplatte aufgebracht und dann mit den Leiterbahnen elektrisch verbunden werden. Die Spannungs- und gegebenenfalls Zusatzklemmen sind also auf der Leiterplatte bereits vormontiert, was eine einfache Endmontage des gesamten Elektrizitätszählers mit sich bringt. Durch die Trennung von Klemmen und Klemmenblock ist außerdem eine einfache Demontage bzw. Montage des Elektrizitätszählers möglich. Dies ist wesentlich für eine Reparatur, da statt des aufwendigen Öffnens des verplombten Gehäuses und des Auslötens der Klemmleiste nur noch ein einfaches Auswechseln des Klemmkörpers erforderlich ist.It is considered to be the essence of the invention that the terminal block can be detached independently of the terminals and part of the terminals, namely the voltage and possibly additional terminals, are attached directly to the circuit board. This arrangement enables the terminals to be automatically applied to the circuit board by an automatic assembly machine and then electrically connected to the conductor tracks. The voltage and possibly additional terminals are thus already pre-assembled on the printed circuit board, which entails a simple final assembly of the entire electricity meter. The separation of terminals and terminal block also makes it easy to disassemble or assemble the electricity meter. This is essential for a repair, since instead of the time-consuming opening of the sealed housing and the soldering of the terminal strip, only a simple replacement of the clamping body is required.
Vorteilhafterweise kann der auf der Leiterplatte befestigte Teil der Klemme elektrisch direkt mit den Leiterbahnen derAdvantageously, the part of the terminal fastened on the circuit board can be electrically connected directly to the conductor tracks
Leiterplatte verbunden sein. Durch diese elektrische Verbindung der Klemmen mit den Leiterbahnen bereits in der Vormontage werden Fehler bei der Herstellung der elektrischen Verbindung in der Endmontage vermieden.PCB connected. This electrical connection of the terminals to the conductor tracks in the pre-assembly prevents errors in the establishment of the electrical connection in the final assembly.
Ferner kann von Vorteil sein, daß die Leiterplatte zumindest bereichsweise auf der Grundplatte aufliegt oder von dieser getragen wird. Damit ist die Unterseite der Leiterplatte geschützt und gleichzeitig ist eine stabile Lagerung der Lei- terplatte gewährleistet.It can also be advantageous that the printed circuit board lies at least in regions on the base plate or is carried by the latter. This protects the underside of the circuit board and at the same time ensures that the circuit board is stable.
Weiterhin kann eine Stromwandler-Baugruppe vorgesehen sein, die lösbar mit der Leiterplatte verbunden ist. Diese lösbare Verbindung trägt wiederum zur einfachen Montage bzw. Demon- tage des Elektrizitätszählers bei.Furthermore, a current transformer assembly can be provided, which is detachably connected to the circuit board. This detachable connection in turn contributes to the simple assembly and disassembly of the electricity meter.
Die Stromwandler-Baugruppe kann Stromklemmen aufweisen, welche ebenfalls schon vor der Montage fest mit der Stromwandler-Baugruppe verbunden sind.The current transformer assembly can have current terminals, which are also firmly connected to the current transformer assembly before assembly.
Die Stromwandler-Baugruppe weist Stromleiter auf, welche so konstruiert sein können, daß sie die Stromklemmen tragen. Da- mit ist eine kompakte Stromwandler-Baugruppe, bestehend aus Stromwandlern, Stromleitern und Stromklemmen geschaffen, welche von einer gewissen Stabilität geprägt ist und ebenfalls der vereinfachten Montage dient.The current transformer assembly has current conductors which can be designed to carry the current terminals. There- is a compact current transformer assembly, consisting of current transformers, current conductors and current terminals, which is characterized by a certain stability and also serves for simplified assembly.
Vorteilhafterweise kann die Stromwandler-Baugruppe zur Endmontage über die Spannungs- und Zusatzklemmen, welche sich auf der Leiterplatte befinden, aufgeschoben werden. Damit hat die vereinfachte Montage gleichzeitig den Vorteil der Kom- paktheit sowie Raumersparnis des fertig zusammengesetzten Bauteils.Advantageously, the current transformer assembly can be pushed on for final assembly via the voltage and additional terminals that are located on the circuit board. This means that the simplified assembly also has the advantage of being compact and saving space on the finished assembled component.
Der Klemmenblock kann konstruktiv so gestaltet sein, daß er als Trennkörper über die Gesamtheit der Klemmen (Strom-, Spannungs- oder Zusatzklemmen) aufsetzbar ist. Der Klemmenblock stellt damit eine Abschirmung bzw. Isolierung zwischen den einzelnen Klemmen dar und dient gleichzeitig der Stabilisierung der relativen Lagen der Klemmen. In dem Klemmenblock sind außerdem die entsprechenden Ausnehmungen vorhanden, um zugehende Kabel einzuführen bzw. Schraubverbindungen zu öffnen bzw. zu lösen.The terminal block can be designed in such a way that it can be placed as a separating body over the entirety of the terminals (current, voltage or additional terminals). The terminal block thus represents a shield or insulation between the individual terminals and also serves to stabilize the relative positions of the terminals. The corresponding recesses are also provided in the terminal block for inserting incoming cables or opening or loosening screw connections.
Eine Abdeckung für sämtliche Bauteile kann zum Schutz dieser vorgesehen sein. Indem die Frontseite des Klemmenblocks gleichzeitig einen Schutz nach außen darstellt, wird diese von der Abdeckung ausgenommen.A cover for all components can be provided to protect them. Since the front of the terminal block also provides protection to the outside, this is excluded from the cover.
Vorteilhafterweise kann es vorgesehen sein, daß der Klemmenblock Arretiermittel zur direkten oder indirekten Fixierung am Gehäuse umfaßt. Ebenso ist es auch möglich, daß der Klemmenblock Arretiermittel zur Fixierung mit der Abdeckung, der Grundplatte, der Leiterplatte, der Stromwandler-Baugruppe oder den Klemmen aufweist. So können beispielsweise Schnappverbindungen oder einfach kompatible Steckverbindungen zwi- sehen den betreffenden Bauteilen vorgesehen sein. Ebenso ist es auch möglich, daß die Grundplatte Halterungen für die Leiterplatte, die Stromwandler-Baugruppe, den Klemmenblock und/oder die Abdeckung aufweist. Auch hier können Schnappverbindungen, Plombiervorrichtungen oder dgl. vorgese- hen sein. Dementsprechend kann auch die Stromwandler-Baugruppe Zapfen oder Platten aufweisen, welche die Leiterplatte durchgreifen und in korrespondierende Ausnehmungen der Grundplatte eingreifen. Damit kann die aufgesetzte Stromwandler- Baugruppe sicher mit der Leiter- und Grundplatte fixiert wer- den.It can advantageously be provided that the terminal block includes locking means for direct or indirect fixing to the housing. It is also possible that the terminal block has locking means for fixing with the cover, the base plate, the circuit board, the current transformer assembly or the terminals. For example, snap connections or simply compatible plug connections can be provided between the relevant components. It is also possible that the base plate has holders for the circuit board, the current transformer assembly, the terminal block and / or the cover. Snap connections, sealing devices or the like can also be provided here. Accordingly, the current transformer assembly can also have pins or plates which pass through the circuit board and engage in corresponding recesses in the base plate. This allows the current transformer assembly to be securely attached to the circuit board and base plate.
Zur Fixierung des Klemmenblocks kann dieser leistenartige Stege aufweisen, welche stiftartige Anformungen der Grundplatte umgreifen.To fix the terminal block, it can have strip-like webs which encompass pin-like projections of the base plate.
Eine weitere vorteilhafte Ausgestaltung der Erfindung kann eine federnde Eichverbindung sein, welche zwischen den Stromleitern und den Spannungsklemmen elektrisch verbindend wirksam ist.A further advantageous embodiment of the invention can be a resilient calibration connection, which is electrically connected between the current conductors and the voltage terminals.
Bei einem Prüf- oder Eichvorgang dient die federnde Eichverbindung der Auftrennung des Spannungspfades. Die federnde Eichverbindung kann durch unmittelbar von den Spannungsklemmen seitlich abstehenden Federzungen gebildet sein, die unter Federdruck mit den Außenflächen der Stromleiter in Verbindung stehen. Diese notwendige elektrische Verbindung zwischen Stromklemmen und Stromleiter wird dann wirksam, wenn die Stromwandler-Baugruppe auf die Spannungsklemmen aufgeschoben wird, wodurch die elektrische Verbindung während des Betriebs stets gewährleistet ist.The resilient calibration connection is used to separate the voltage path during a test or calibration process. The resilient calibration connection can be formed by spring tongues which project directly to the side from the voltage terminals and which are connected to the outer surfaces of the current conductors under spring pressure. This necessary electrical connection between the current terminals and the current conductor becomes effective when the current transformer module is pushed onto the voltage terminals, as a result of which the electrical connection is always guaranteed during operation.
Beim Eichvorgang kann ein Trennstecker im Bereich der Spannungsklemmen eingeführt werden, der die Federzungen von den Stromleitern abbiegt. Damit ist der Spannungspfad unterbro- chen und der Eichvorgang kann ohne Öffnen/Schließen der Eichverbindungen mittels Schrauben und Schiebelaschen stattfin- den. Somit kann auch das Schließen der Eichverbindung nicht mehr vergessen werden.During the calibration process, an isolating plug can be inserted in the area of the voltage terminals, which bends the spring tongues from the current conductors. The voltage path is thus interrupted and the calibration process can take place without opening / closing the calibration connections using screws and sliding tabs. the. This means that closing the calibration connection can no longer be forgotten.
Zur Abschirmung des Stromwandlers kann an dem Kleπt enblock eine oberseitige Abschirmung vorgesehen sein. Somit erfüllt der Klemmenblock gleichzeitig die Aufgabe der Trennung und Stabilisierung der Klemmen sowie die oberseitige Abschirmung der Stromwandler. Die unterseitige Abschirmung der Stromwandler kann durch eine Platte, welche an der Grundplatte vorge- sehen ist, erfolgen.To shield the current transformer, an upper-side shield can be provided on the adhesive block. The terminal block thus fulfills the task of separating and stabilizing the terminals and shielding the current transformers at the top. The current transformers can be shielded on the underside by a plate provided on the base plate.
Die Erfindung ist anhand eines vorteilhaften Ausführungsbeispiels in der einzigen Zeichnungsfigur näher erläutert. Diese zeigt eine explosionsartige und perspektivische Darstellung des Elektrizitätszählers.The invention is explained in more detail using an advantageous embodiment in the single drawing figure. This shows an exploded and perspective view of the electricity meter.
Die explosionsartige Zeichnung stellt gleichzeitig die Mon- tierbarkeit der einzelnen Bauteile des Elektrizitätszählers dar. Der Elektrizitätszähler setzt sich im wesentlichen aus einer Grundplatte 4, einer elektrischen Klemmenanordnung, einer Leiterplatte 3 sowie einer Abdeckung 8 zusammen. Die Grundplatte 4 mit der Abdeckung 8 bilden dabei das Gehäuse. Dabei umfaßt die Klemmenanordnung einen Klemmenblock 1, der von den Klemmen lösbar angeordnet und extra montierbar ist. Ein Teil der Klemmen, die Spannungsklemmen 2 und eventuell weitere Zusatzklemmen sind unmittelbar auf der Leiterplatte 3 befestigt.The explosive drawing simultaneously represents the ability to mount the individual components of the electricity meter. The electricity meter essentially consists of a base plate 4, an electrical terminal arrangement, a printed circuit board 3 and a cover 8. The base plate 4 with the cover 8 form the housing. The terminal arrangement comprises a terminal block 1, which is detachably arranged from the terminals and can be assembled separately. Some of the terminals, the voltage terminals 2 and possibly other additional terminals are attached directly to the circuit board 3.
Dabei sind diese auf der Leiterplatte 3 befestigten Klemmen elektrisch direkt mit den Leiterbahnen der Leiterplatte 3 verbunden.These clamps fastened on the printed circuit board 3 are electrically connected directly to the conductor tracks of the printed circuit board 3.
In zusammengesetztem Zustand liegt die Leiterplatte 3, zumindest bereichsweise, auf der Grundplatte 4 auf bzw. wird von dieser getragen. Ferner ist zwischen Klemmenblock 1 und Leiterplatte 3 eine Stromwandler-Baugruppe 5 vorgesehen, die ebenfalls lösbar mit der Leiterplatte 3 verbunden ist. Die Stromwandler-Baugruppe 5 weist an ihrem vorderen Ende Stromklemmen 6 auf, welche von den Stromleitern 7 getragen werden. Die Stromleiter 7 stehen wiederum mit den Stromwandlern 18 direkt in Verbindung. Schließlich ist der Klemmenblock 1 als Trennkörper bzw. zur Isolierung über die Gesamtheit der Klemmen (Strom- 6, Spannungs- 2, Neutralleiter- 19 sowie eventuell Zusatzklemmen) aufsetzbar.In the assembled state, the printed circuit board 3 lies, at least in some areas, on the base plate 4 or is carried by the latter. Furthermore, a current transformer assembly 5 is provided between the terminal block 1 and the printed circuit board 3, which is also detachably connected to the printed circuit board 3. The Current transformer module 5 has current terminals 6 at its front end, which are carried by current conductors 7. The current conductors 7 are in turn directly connected to the current transformers 18. Finally, the terminal block 1 can be placed as a separating body or for insulation over the entirety of the terminals (current 6, voltage 2, neutral conductor 19 and possibly additional terminals).
Der Klemmenblock 1 dient außerdem zur Lagestabilisierung der einzelnen Klemmen. Es existiert außerdem eine oberseitige Abschirmung 16 für die Stromwandler 18. Die unterseitige Abschirmung 17 der Stromwandler 18 erfolgt durch ein platten- förmiges Element, welches mit der Grundplatte 4 in Verbindung steht. Die Grundplatte 3 weist Halterungen für den Klemmen- block 1 und die Abdeckung 8 auf. So ist ein sicherer Halt bzw. Verschluß der Abdeckung 8 mit Schnappverbindungen 14, 14' bzw. Plombierungen 15, 15' gewährleistet. Zur Fixierung des Klemmenblocks 1 auf der Grundplatte 4 weist dieser leistenartige Stege 9 auf, welche stiftartige Anformungen 10 der Grundplatte 4 umgreifen. Zusätzliche Arretiermittel der einzelnen Bauteile können vorgesehen sein, sind aber in der Zeichnungsfigur nicht näher angegeben.Terminal block 1 also serves to stabilize the position of the individual terminals. There is also a top-side shield 16 for the current transformers 18. The bottom-side shield 17 of the current transformers 18 is provided by a plate-shaped element which is connected to the base plate 4. The base plate 3 has holders for the terminal block 1 and the cover 8. This ensures a secure hold or closure of the cover 8 with snap connections 14, 14 'or seals 15, 15'. To fix the terminal block 1 on the base plate 4, it has strip-like webs 9 which engage around pin-like projections 10 of the base plate 4. Additional locking means of the individual components can be provided, but are not specified in the drawing figure.
Der erfindungsgemäße Elektrizitätszähler weist weiterhin eine federnde Eichverbindung 12 auf, die im zusammenmontierten Zustand zwischen den Stromleitern 7 und den Spannungsklemmen 2 elektrisch verbindend wirksam ist.The electricity meter according to the invention furthermore has a resilient calibration connection 12 which, in the assembled state, has an electrically connecting effect between the current conductors 7 and the voltage terminals 2.
Die federnde Eichverbindung 12 wird durch unmittelbar von den Spannungsklemmen 2 seitlich abstehenden Federzungen 13 gebildet. Beim Aufschieben der Stromleiter-Baugruppen 5 beaufschlagen die Federzungen 12 die Außenflächen der Stromleiter 7 und stehen mit diesen elektrisch in Verbindung.The resilient calibration connection 12 is formed by spring tongues 13 which project directly to the side from the voltage terminals 2. When the current conductor assemblies 5 are pushed on, the spring tongues 12 act on the outer surfaces of the current conductors 7 and are electrically connected to them.
Beim Eichvorgang sind die Federzungen 13 durch einen Trennstecker von den Stromleitern 7 zur Auftrennung des Spannungspfades abhebbar. Dazu muß der Trennstecker in den Bereich der Spannungsklemmen 2 und der Federzungen 13 eingeführt werden. Der Eichvorgang kann sodann ohne Öffnen/Schließen der Eichverbindungen mittels Schrauben und Schiebelaschen stattfinden.During the calibration process, the spring tongues 13 can be lifted off from the current conductors 7 by a separating plug in order to separate the voltage path. To do this, the isolating plug must be in the area of Voltage terminals 2 and the spring tongues 13 are introduced. The calibration process can then take place without opening / closing the calibration connections using screws and sliding tabs.
Die Montage des Elektrizitätszählers erfolgt also zunächst durch das Einlegen der Leiterplatte 3, auf welcher bereits die Spannungsklemmen 2 und eventuell Zusatzklemmen befestigt sind, auf die Grundplatte 4. Dann wird die Stromwandler-Bau- gruppe 5 (mit den Stromklemmen 6, den Stromleitern 7 sowie den Stromwandlern 18) und Neutralleiterklemmen 19 von oben aufgesetzt und durch Halteelemente in der Grundplatte positioniert. Anschließend wird der Klemmenblock 1 einfach von oben über die Klemmen geschoben und durch Verschlußmuttern fixiert. Mit dem Aufsetzen der Abdeckung 8 ist die einfache Montage schließlich beendet. The electricity meter is first installed by inserting the circuit board 3, on which the voltage terminals 2 and possibly additional terminals are already attached, onto the base plate 4. Then the current transformer assembly 5 (with the current terminals 6, the current conductors 7 and the current transformers 18) and neutral conductor terminals 19 from above and positioned by holding elements in the base plate. Then the terminal block 1 is simply pushed over the terminals from above and fixed with locking nuts. When the cover 8 is put on, the simple assembly is finally ended.
