Definitions

  • Electricity meter with a housing, an electrical terminal arrangement and a circuit board
  • the invention relates to an electricity meter according to the features of the preamble of patent claim 1.
  • 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.
  • 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.
  • 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.
  • 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.
  • the part of the terminal fastened on the circuit board can be electrically connected directly to the conductor tracks
  • 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.
  • 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.
  • the current transformer assembly can have current terminals, which are also firmly connected to the current transformer assembly before assembly.
  • the current transformer assembly has current conductors which can be designed to carry the current terminals.
  • 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.
  • the current transformer assembly can be pushed on for final assembly via the voltage and additional terminals that are located on the circuit board.
  • the simplified assembly also has the advantage of being compact and saving space on the finished assembled component.
  • 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.
  • 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.
  • 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.
  • the terminal block can have strip-like webs which encompass pin-like projections of the base plate.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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).
  • Terminal block 1 also serves to stabilize the position of the individual terminals.
  • 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'.
  • 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.
  • 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.
  • 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.
  • 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.
