    Counter block for an electricity meter and electricity meter
    The present invention relates to a meter switching block for a connection of an electricity meter and an electricity meter. Such a switching block has at least two meter switching contacts per phase, while a corresponding electricity meter has at least two contacts per phase, typically using 3-phase devices.
    With the help of such a counter switching block, it is possible to connect relatively easily electricity meter or replace. In the case of exchanging an elasticity counter, there are further known bridging means which are insertable in the counter switching block and which each bridge two associated contacts of one phase, so that the electricity meter can be taken out and replaced or exchanged without disconnecting the customer equipment from the mains got to.
    Such counter-switching blocks and electricity meters and corresponding bridging devices, which are sometimes referred to as., Zählsteckklemme "are known for example from DE 75 29 435.8 Ul or from DE 200 18 372 Ul.
    It is an object of the present invention to further improve a meter switching block, an electricity meter and / or a bypass device, in particular with regard to the qualitative characteristics and the lifetime of such devices, also with regard to the number of possible changes of the electricity meter.
    This object is achieved by a counter switching block according to claim 1, an electricity meter according to claim 13 and a bridging device according to claim 14. The claims 2 to 12 relate to particularly advantageous embodiments of the counter switching block according to the invention, the claim 15 relates to a particularly advantageous embodiment of the bridging device according to the invention. 2 * # ** ·· ♦ · · · «· ·« «* * · ·« «* *« * * «·» »····» · * * »· · · * ι ·» * · ♦ · · ··· ** · * ··· «« · »« «· · |
    According to the invention, a counter switching block for at least two counter switching contacts per phase is provided for a connection of a leakage counter, which also comprises at least two contacts per phase, each counter switching contact being designed to be able to decouple an associated contact piece of the leakage counter, so that an electrical connection can be produced between the contact pieces and the Zählschahkontakten.
    A housing of the counter switching block has at least one opening. which is trained so that at least a part of a Übrbrückungseinrichtung, also called counter switching handle, is inserted into this at least one opening. so that each two Zählcrscbaltkontakte a phase can be bridged by means of the bridging device. This makes it possible to herauszunchmcn the electricity meter, for example, to replace it without the customer system must be disconnected from the network.
    According to the invention, there is provided a spring device which is so shaped that it contacts a predetermined contact pressure or contact pressure between the counter switching contact or parts of the counter switching contact such as contact points, contact lines or contact surfaces, and the associated contact piece or parts of the associated contact piece of an electricity meter can generate when the Kontakistück is inserted into the ZählschaltkontakL, which is typically the case when the Elektrizitätszählcr is inserted with the contact pieces in the Zählschaltblock.
    According to the invention, the divider switch block comprises at least one switch element, each counter switch contact being designed in this way. in that it can be switched back and forth between an operating position and a removal position by means of a switching element.
    According to the invention the at least one Schaltclemcnt and each counter switch contact are further designed so that the counter switch contact is in the removal position when the Überbrbrückungseinrichtung or the Zählschaltgriff is inserted into the Zälilerschaltblock, the predetermined Kontakldruck or contact pressure between the counter switch contact and the associated contact piece in the Removal position is lower than in the Betriebsposilion and / or the contact pressure is canceled or almost canceled and / or a contact between the Zählschaltkontakt and the associated contact piece is completely canceled or prevented, at least in the state in which the Elektrizitätszählcr still in its original position located for the Beirieb. It is of course not to be ruled out in this case that in cases where a user removes the electricity meter from the meter switching block, typically pulls the electricity meter from the meter switching block, forces on the Elcktrizitätszähler or Kontaklstücke act, for example, by uneven withdrawal of the electricity meter by the user, cause during this process, in some places or for certain periods, a higher contact pressure arises, for example, when the electricity meter is twisted or tilted during extraction.
    The embodiment of the invention has the advantage that when removing the Elektrizitätszählcrs, in which the contacts of the electricity meter are pulled out of the counter switching contacts of the counter switching block, no friction between counter switching contact and contact piece is formed or this friction is at least reduced. This noticeably reduces the wear of the corresponding parts, which is of particular importance because, in the prior art device, the wear occurs exactly at the points where the electrical contact and the connection are to be restored after a renewed wiping operation that wear very quickly leads to poor electrical contact and to shorten the life of the devices.
    By the counter switching block according to the invention, therefore, both the life of the counter switching block itself and the life of the Elcktrizitätszähler is significantly increased, also the quality of the contacts and thus the quality of the function of the Zählschaltblocks and the Elektrizitätszählcrs is significantly increased during life.
    The lower friction or even the cancellation of the friction causes the materials of Zählcrschaltkontakte and the contact pieces can be selected only in terms of their actual task, namely the line and the Kontakthersteilung, in contrast, to the devices according to the prior art , in which the resistance to the above-described Verschleißerschcinungen and thus the hardness of the material must be taken into account.
    Typically, in the prior art devices, for example, hard nickel plated brass is used as the material for the counter contacts and the contacts, although the conductivity of this material is limited to ensure that a hard material is provided in which the wear is at least is acceptable to allow a meaningful life, so that the selected material is merely a compromise. In particular, hard nickel-plated brass has the problem that nickel oxide forms on the surface, which further hampers or restricts the conductivity.
    On the other hand, in a counter switching block according to the present invention, it is possible to use, for example, copper or aluminum, in particular silver-plated copper or galvanized copper, which have much better conductivities but are a softer material, thereby also compromising the quality and performance of the counter switching block and the electricity meter can be increased.
    Another advantage of the present invention is that with the onset of bridging, even before the removal of the electricity meter, the connection to the electricity meter can be safely disconnected so that there are unique switching states.
    The electricity meter can therefore be removed, for example, while at the time of removal already no electrical connection between the contact pieces of the electricity meter and the Zählschaltkontakten counter switch block is present, so that, for example, a sparkover, also to increased wear on the one hand and not desired and uncontrolled current peaks in Network, on the other hand, can be avoided. This also significantly increases the quality and life of the devices.
    Due to the above-mentioned embodiment of the invention and the advantages described, it is also possible, for example, to realize higher outputs. Typically, the devices should be designed, for example, for 63 A or 100 A, but in reality cs, in contrast, is often the case in the prior art, because of the wear that has already taken place and due to the materials used and the resulting inadequate contact, significantly less power is realized can be. The inventive
    On the other hand, the device ensures, over the entire extended life of the devices, that the specified power can actually be transmitted, and also makes it possible to provide higher performance devices.
    According to a particular embodiment, the counter switch contacts are formed substantially egg-shaped, wherein they preferably comprise two opposing legs between which a contact piece of a Elcktrizitätszahlers is cinsctzbar.
    Preferably, the legs face each other and have, at least partially, substantially co-planar contact surfaces or partial surfaces.
    Such a C-shaped configuration of the Zählcrschaltkontakte and the substantially co-planar contact surfaces in particular has a great advantage when contacts with square, rectangular, hexagonal or polygonal cross-sections are used, which in turn are very advantageous for a Elektrizitätszähl, as also described below will be.
    In a preferred embodiment, at least one spring device is provided, which is designed so that it on the tavern! Of course, and in the context of this invention, a spring device is of course independent of the configuration of the counter switch contacts, and a spring device can also be provided for any other counter switch contacts, the spring device serving the Zählcrschaltkontakte in some way "pretension" and / or to increase the contact pressure or contact pressure with an inserted contact pin to produce a better contact.
    As spring device different springs, both in terms of the type and the positioning can be provided. One possibility is cs, for example, in the case of C-shaped ausgecbildcten Zählcrschaltkontakten to provide a single spring for each leg, which biases the legs toward a contact piece to be inserted. However, it is also possible to provide a single Federclement that, for example, in the case of a C-förmigcn or substantially C-fönnigen Zählcrschaltkontakts, both legs engages around and compresses them. It is also possible for the spring device to be integral
    · * ··· ** ·· # · t · • · * * · · · · * * * · ** ·· · 1 · * | t · f * · · · > Is formed with the counter switch contact and / or the counter switch contact itself is a spring element which is biased in a certain direction.
    Preferably, the switching element between an operating position and a removal position is switched back and forth, wherein preferably in a removal position pressure is exerted on at least parts of the counter switching contacts, which counteracts the spring force of the at least one spring device (or against the bias of the counter switching contact itself) acts.
    This has the advantage that the switching element can reduce the contact pressure or the Anprcssdruck between Zählcrschaltkontakt and contact piece in a relatively simple manner or even completely cancel, so that, with the achievement of the above advantages, the contacts without friction or reduced friction and thus with reduced or can be removed without wear.
    Particularly preferably, the Schaltelemcnt is at least partially formed as a shift lever and / or displaceable between the operating position and the removal position and / or rotatable trained. This realizes a particularly simple mechanical realization of the desired function, as has been described above.
    It is particularly advantageous in a rotatable Schaltclement if this comprises a Exzentcr, which is designed so that in the removal position of the eccentric is positioned so that it the contact surfaces, contact lines or contact points of the counter switching contact against the bias or away from the associated contact pieces bcw ' egt, so that the contact pressure or contact pressure is reduced or preferably a contact between the Zählcrschaltkontakten and the associated contact pieces is completely canceled.
    In a particularly preferred embodiment, the Schaltelcmeni on a connection Bercich or also connection or Betäligungsbereich which is formed so that it can cooperate with a corresponding connection area (or connection or Betäligungsbereich) of the Brückungscinrichlung so that when inserting the Überbrbrückungseinrichtung the Schaltclement and / or the Zählcrschaltkontakt is automatically or forcibly moved to its removal position.
    This ensures in a simple manner that the switching element is in its removal position when the bridging device is used, so that a friction-free or friction-reduced removal of the electricity meter is possible.
    The connection regions of the switching element and the bridging device can be designed differently, for example, one connection region, for example of the switching element, can have a recess or groove, for example a V-shaped groove, while another connection region, for example the override device, comprises a projection or pin which engages in the recess or groove and thereby moves the switching element.
    The connections between the two connection regions can be positive or non-positive or comprise both possibilities.
    In one embodiment, each one switching element for two counter switching contacts a phase is provided. This ensures a simple and therefore cost-effective design.
    In another embodiment, all the switching elements in a counter switching block are coupled together so that they are always in the same state, either in the operating position or in the picking position. This ensures that even in the event that, for example, in multiple phases, a malfunction in one of the switching elements should take place, for example, because a projection or pin, which is to act as a connection portion of the Überbrbrungsierungsrichtung is aborted, moves all switching elements in the removal position become.
    In another embodiment, it is also possible that only one switching element is provided, which is designed so that it can reciprocate each meter switching contact between the operating position and the removal position. In such cases, cs is also possible in the case of polyphase devices, that only a single corresponding connection region of the bridging device can be provided, and accordingly only a single opening for engaging a part of the bridging device in the housing of the counting circuit block needs to be provided.
    The invention further relates to an electricity meter with two contact pieces per phase, which is connectable to a counter switching block, in particular according to one of the preceding claims, with at least two Zählschaitkontakten per phase, each Kontakistiick having a rectangular, hexagonal or polygonal cross-section.
    In contrast to the conventionally round cross-sections according to the prior art, the rectangular or polygonal cross-section has the advantage that a plurality of clearly defined contact lines between the contact piece and the associated connection piece are realized in the elasticity counter.
    This leads to a better defined and thus more powerful electrical connection, in particular in comparison to the annular in cross-section trained Fcderelcmentcti for receiving round contact pieces, but not completely applied due to manufacturing tolerances, but rather have rather random contact contacts that in a smooth transition to Gaps between the contact piece and associated connector in the electricity meter lead, which also increases the wear and results in that not the full power can be transferred.
    In a preferred embodiment, each contact piece has a key dimension, ie from surface to surface, of 5 mm, while the corner dimension, ie the distance between two corners, is greater than 5 mm. This has the advantage that a prior art electricity meter with cross-section circular contacts and a diameter of 5 mm can be used with a new counter switching block according to the invention, but on the other hand it can be ensured that an elasticity counter according to the invention is not included a counter switch block according to the prior art having the disadvantages described above can be used.
    The invention further relates to a bridging device and an overall system comprising a counter switching block with an elasticity counter and / or with a bridging device, as described above. Further features and advantages of the invention will be more apparent from the following drawings:

    Figure 1 shows a perspective view of a fülmmgs form of a counter switching block 100 according to the invention, a erfmdungsgemäßen bridging means 200 and an inventive Elektrizitätszähiers 300. The electricity meter 300 is not used in Fig. 1 in the counter switching block, the lock-up device 200 and the Zählschaltgriff is partially in the Counting block 100 is used.
    This embodiment is a 3-phase system. At the electricity meter 300, a total of 7 contact pieces 320 can be seen very well, which can be inserted into associated meter switching contacts of the meter switching block 100. The contact pieces 320 are each two contacts 320 per phase and a contact piece for an N-Leitcr.
    In this embodiment, the contact pieces have a hexagonal cross-section, which provides advantages in terms of secure contact and good electrical connection both between the contact pieces 320 and further electrical leads within the electricity meter 300 (see also Figs. 7 and 8, Figs show a further embodiment with contact pieces 320 which have a square cross section), as well as between the contact pieces 320 and associated Zählschaltkontaktcn of Zählcrschaltbloclcs (see, for example, Fig. 3 in conjunction with Fig. 6).
    FIG. 2 shows an embodiment of a bridging device 200 according to the invention or of a meter switching handle. The lock-up device 200 includes a handle 210 that can be grasped by the user so that he can operate the lock-up device 200 and, if necessary, operate on the counter switching block.
    The bridging device 200 has a total of 4 bridging clasps 220 extending from a lower portion of the bridging device 200, which in this embodiment are formed substantially in the form of elongate or plate-shaped protrusions.
    Three of the bridging elements 220 have an eccentric bridging contact L 222, one per phase, which in turn is located in the upper region, that is to say in a region closer to the handle 210, of a contact protection 224 which is made of electrically insulating material
    Material is made, covered. One of the bridging elements 220, namely the left bridging element in FIG. 2, which is provided for the N conductor, has a contact 223 which can contact the N line. This may be of importance if an electronic board is used in the bridging device 200, which indicates a rotating field recognition, as this additionally requires contact with the N-conductor.
    Further, each bridging member 220 includes a protrusion 226 which forms a connecting portion of the bridging means and which can engage or interact with an associated connecting portion of a switching member to actuate the switching member, as shown particularly in FIGS. 3 and 4.
    FIG. 3 shows a cross-section through a counting circuit block 100 according to the invention and a bridging device 200, which has not yet been inserted in the counter switching block 100. In the case of the bridging device 200, it is particularly easy to see the bridging contact 222, the contact protection 224 and the projection 226. The bridging device 200 can be used in an opening 170 of the counter switching block 100, see the following description of FIG. 4. The opening 170 is designed so that you can not reach with the finger bridging device 200 to conductive parts, so that a Protection against contact is ensured.
    In the cross section shown in Fig. 3 is also seen very well a substantially egg-shaped counter switching contact 120 with two legs, wherein the legs are Fedkrelementen 122 which compress the legs of the counter switch contact 120 to a contact pressure or a contact pressure between the Kontaktbercichcn of the counter switch contact 120 and of a contact piece 320 of an electricity meter. In FIG. 3, only the contact piece 320 is shown without showing further details of the electricity counter.
    The counter switching block shown in Fig. 3 further comprises a switching element 140 which is formed in the form of a shift lever and an eccentric 142 and a Verbindungsbcrcich 144, the switching element 140 isL arranged so that the eccentric 142 rotatably disposed between the legs of the Zählschaltkontakt 120 is that in the region of the Exzcntcrs 142 are substantially parallel to each other. Ί1

    The Schaltclemcnt 140 is located in Fig. 3 in the operating position, the longer axis of the eccentric is not effective here, so that the legs of the Zählschaltkontakt 120 are pressed by means of the springs 122 to the contact piece 320.
    It should already be pointed out at this point that cs is a contact piece with a hexagonal cross-section in the contact piece 320, so that a surface contact is established between the counter-switching contact 120 and the contact piece 320.
    Now, when the lock-up device 200 is inserted in the counter switching block 100, as shown in FIG. 4, the projection 226 acting as the connection portion of the lock-up device engages the connection portion 144 of the switching element 140, which is shaped in the form of a substantially V-shaped groove ,
    By shifting the bridging device 200 downwards in FIG. 3, therefore, the shifting element 140 is brought from its operating position (see FIG. 3) into a removal position (see FIG. 4).
    In the case of the switching element 140 shown here, the sound element is rotated about an indexing axis, which is located substantially in the center of the eccentric 142, by an angle of approximately 40 degrees. However, it should be noted at this point that au eh other Schalteleincnte can be provided, which have a different pivot point and / or which can also be moved in the longitudinal direction.
    As can be seen in FIG. 4, which shows the removal position, the longer axis of the eccentric 142 now lies directly between the limbs of the meter switch contact 120, so that they are pressed outward counter to the spring force of the springs 122. The connection between counter switch contact 120 of the counter switch block 100 and contact piece 320 of the Elcktrizitätszählcrs is thereby canceled, there is a gap between counter switch contact 120 and Koniaktstück 320,
    The Elcktrizitätszählcr can therefore be removed with its contact pieces 320, wherein no contact and therefore no friction between counter switch contact 1 20 and contact piece 320 is formed. An Elcktrizitätszählcr with the associated contact pieces 320 can therefore be any number of times and used without affecting the life of the devices or their quality negative.
    If now the bridging device 200 is removed again, i. pulled upward in Figure 4, the Schaitelemcnt 140 is automatically and forcibly moved by engagement of the projection 226 in the groove 144 back to the operating position, see Fig. 3.
    FIG. 5 shows a cross section through the embodiment shown in FIG. 4 along the line B-B. FIG. 5 shows very clearly how a connection can be established between two counter switch contacts 120 of the counter switch block by means of a bridging contact 222 of the bridging device 200, so that the two counter hold contacts 120 are bridged,
    5 that the counter switch block 100 includes another spring device 170 which presses on a counter switch contact 120, in FIG. 5 laterally, so that a contact pressure between the counter switch contacts 120 and the bypass contact 222 is established.
    The bridging contact 222 lies directly between rear sides 126 of the counter switching contacts 120 (see also FIG. 6), so that a very direct contact and short routes are achieved in the bridging state.
    Figure 6 shows another embodiment of a counter contact 120 which is very similar to the counter contacts 120 described in the preceding figures, so that identical reference numerals have been used for the same or similar elements and reference is made to the preceding description to avoid repetition.
    Instead of the two springs biasing the legs of the meter switch contacts 120, in this embodiment a single spring 122 is provided which is substantially C-shaped and includes and thereby compresses the two legs of the count circuit 120 and biases it in the direction of a contact gap to be inserted ,

    Very clearly in Fig. 6, the back 126 of the Zählschaltkontakts 120 can be seen, which can be brought into contact with the bridging contact 222 of the lock-up device, see Fig. 5 and the associated description.
    A lead 150 is attached by means of a lead spring 160 to the outside of the rear face 126 of the counting contact switch, so that easy insertion of the lead 150 is possible.
    Figure 7 shows a perspective view of an embodiment of a Schaltelcments L40, which includes an eccentric.
    The switching element 140 comprises a connecting region 144, which is designed as a substantially V-shaped groove, into which, for example, a projection 226 of the bridging device 200 can engage, see FIGS. 3 and 4.
    Clearly visible is also the eccentric 142, which comprises a circular or tubular in cross-section element which is rotatably mounted in the Zählsehaltblock, wherein projections or projections 148 are formed on two sides, which realize the eccentric.
    FIG. 8 shows in cross section some parts of an electricity meter according to the invention with a contact piece 320, which in this embodiment has a rectangular cross section. The contact piece 320 is fastened by means of two screws 342 in a receiving contact 340 within the housing of the electricity meter 300.
    FIG. 9 shows a plan view of the embodiment shown in FIG. 8, wherein the annular front part of the receiving contact 340, the cross section of the contact 320 and the eyebrow 342 are very clearly visible. Due to the quadrangular cross section, two clearly defined contact lines between contact piece 320 and receiving contact 340 are produced. Furthermore, the geometrical choice of the cross-section of the concertina piece 320 ensures that the positioning of the contact piece 320 within the receiving contact 340 by pressing the screw 342 on a surface of the contact piece 320 always occurs exactly in the same way, so that a clearly defined
    Contact between contact piece 320 and receiving contact 340 is made, which also enables cs to transmit high powers.
    The features disclosed in the foregoing description, claims and drawings may be significant to the practice of the invention in its various forms both individually and in any combination thereof.
