Definitions

  • the invention relates to a circuit board terminal arrangement according to the preamble of claim 1.
  • Such basic circuit board terminals are known according to their basic structure (DE-B-2 035 326).
  • the connection pins for the electrical connection between the tracks of the circuit board and the conductor connection are formed in the terminal for in particular soldering, but also wrap or plug connections.
  • the structure is relatively complicated. The assembly is also complicated due to the need for screwing.
  • the present invention has for its object to provide a circuit board terminal arrangement of the generic type, which ensures a particularly simple, in particular solderless or screw-free assembly of the circuit board terminals on the circuit board with the required electrical but also high mechanical security.
  • each terminal of the arrangement has at least one housing pin
  • a single-pole terminal for example, in addition to the connecting pin designed as a press-in pin for mechanical anchoring, also has the housing pin, which in particular can absorb the forces which occur when the clamping screw is tightened when a conductor is connected to the conductor connection of the terminal .
  • the printed circuit board terminals can now be connected to the printed circuit board using a press-fit technique, and the wiring work can be carried out subsequently, without the risk of the electrical press-in connection being removed. Since the contacting press-in pin is closely guided in the interior of the terminal housing right up to the outlet therefrom, perfect installation is also ensured, taking into account the relatively high forces that occur during the press-in process.
  • the housing pin protrudes further beyond the corresponding housing surface of the terminal than the press-in zone of the press pin or pins, the guide of the housing pin in the mounting hole of the printed circuit board starts even before the actual press-in process of the connecting pin. Any tilting possibility of the clamp which impairs the electrical press-in connection when pressed in is switched off.
  • the contacting press-in pin is also firmly connected to the housing via a latching lug.
  • the force for the press-in process can be carried out directly over the surface of the terminal housing without special additional tools.
  • a three-pole circuit board terminal is provided.
  • the circuit board terminal could also have fewer poles, in particular also be single-pole and it could also have more poles.
  • the circuit board terminal according to FIGS. 1 and 2 has an insulating plastic housing 1, in which there are three conductor connections 2 in the exemplary embodiment shown for connecting the incoming electrical conductors.
  • the conductor connections 2 each have a clamping screw 2a, by tightening the inserted conductor is connected.
  • a connector pin 3 leads from each conductor connection 2 to the underside of the housing 1.
  • the connector pins 3 emerge from the underside of the housing. They are now designed as press-in pins and have a tapered insertion zone 4 on the underside of the housing 1 at their free end and, above that, adjacent to the underside of the housing 1, a press-in zone 5.
  • the printed circuit board 6 shown in FIG Holes 7 which are metallized throughout in a corresponding grid, into which the press-in pins 3 are pressed with electrical contact and a certain mechanical hold.
  • the housing 1 of the circuit board terminal is now provided on the underside in the exemplary embodiment shown with three housing pins 8.
  • the mutually assigned Press-in pins and housing pins each together in the central longitudinal plane of the affected pole, as can be seen in particular from FIG. 2. Deviating from this, it would be conceivable to provide only one housing pin for a two-pole terminal, or only three housing pins for a four-pole terminal.
  • receiving holes 9 are provided for the housing pins 8 in a corresponding grid. If wiring work is carried out in the press-in technology after connecting the printed circuit board terminal to the printed circuit board and possibly not inconsiderable forces are applied to the respective pole point by means of the clamping screw 2a when the conductor is fixed, these forces are now not only via the pressed-in press-in pins 3, but in particular also via the housing pins 8 are accommodated in a manner preventing canting, tilting, twisting of the circuit board terminal or even destruction in the connection area between the circuit board terminal and the circuit board.
  • the housing pins 8 are designed for this function in terms of shape, length and diameter, as well as to prevent the clamp from tilting when pressed in. Therefore, as can be seen in particular from FIG. 2, the housing pins 8 each project further downward over the housing underside than the press-in zones 5 of the press-in pins 3. This means that the guide through the housing pins in the mounting holes 9 of the printed circuit board already starts before the actual press-in process of the press-in pins 3 begins in their press-in zones 5.
  • the pin guide accompanies the press-in process to the end.
  • the press-in pin is guided closely in the housing 1 of the printed circuit board clamp as close as possible to the press-in zone 5.
  • it is firmly connected to the housing 1 with a locking lug 10. Thanks to this configuration, the introduction of force for pressing in can take place directly over the surface of the housing 1 without a special additional tool.
  • the number of housing pins can be less than that of the press-in pins.
