Definitions

  • the present invention relates to a (multi-pole) connection terminal which can be plugged onto contact pins - for example a circuit board - for electrical contacting.
  • Connection terminals are generally known from the prior art. These are used for the electrical connection of electrical conductors.
  • the connection terminals can be provided loosely or can also be mechanically fastened.
  • Connection terminals are also generally known which are fastened directly to circuit boards in order to simplify the electrical connection of electrical conductors to the circuit board.
  • Such connection terminals generally have integrated contact projections by means of which they are plugged onto circuit boards and then generally permanently soldered to them. In particular, such a soldering process requires appropriate soldering temperatures, which can affect the insulating housing of a connection terminal to be fastened in this way, which is usually made of plastic.
  • Such known terminals generally only have a connection option for electrical conductors from one side, so that the through-wiring preferred for connection terminals cannot be implemented or can only be implemented with great effort.
  • connection terminals are known from the prior art, which are used in luminaires and are often provided integrated in a luminaire body of the luminaire; for example, clipped into it. These connection terminals are used in particular for looping through a through-wiring on the one hand and for optionally tapping off the through-wiring on the other hand; for example, to corresponding luminaire components, such as a luminaire operating device.
  • connection terminal and a printed circuit board arrangement equipped therewith, which enable simple and secure electrical contacting of the connection terminal with high flexibility for providing through-wiring.
  • the present invention relates to a connection terminal which has at least two contact elements.
  • Each of the contact elements in turn has two electrically connected conductor terminals each for electrical connection to an electrical conductor for providing through-wiring via the contact element.
  • the connection terminal has an insulating housing that accommodates the contact elements (preferably at least partially or completely).
  • the insulating housing delimits at least part of a conductor insertion channel leading from the outside to the respective conductor terminal point.
  • the conductor insertion channels assigned to the same contact element extend along the same axis of extension or at least substantially parallel to this, and are directed away from one another.
  • Each of the contact elements has a contact terminal point for receiving a contact pin.
  • the contact terminal points are in turn each electrically connected to the conductor terminal points of the assigned contact element; thus, the contact terminal point and the conductor terminal points of the same contact element are electrically connected to one another.
  • the insulating housing delimits at least part of contact insertion channels leading from the outside to the respective contact terminal points.
  • the contact insertion channels each extend along a further axis of extension, which is oriented substantially perpendicular to the axis of extension of the assigned conductor insertion channels - i.e. those assigned to the same contact element.
  • the fact that the conductor insertion channels extend along the same extension axis and are directed away from one another is understood to mean that the conductor insertion channels are aligned coaxially with one another and their accesses from the outside (i.e. the conductor insertion openings) are on opposite sides; i.e. they are open and accessible facing away from each other.
  • the fact that the conductor insertion channels extend (essentially) parallel to the same extension axis and are directed away from one another is understood to mean that the conductor insertion channels are radially offset from one another when viewed in the axial direction, but preferably still overlap when viewed in the axial direction, so that their entrances from the outside (i.e.
  • the conductor insertion openings are on opposite sides; i.e. they are open and accessible facing away from each other.
  • substantially parallel (to the extension axis) is understood to mean that the extension direction can be inclined with respect to the extension axis by a maximum of approximately 20°, preferably a maximum of approximately 10°; can therefore extend in a cone of 20° or 10° around the extension axis (longitudinal).
  • substantially perpendicular to the extension axis
  • the further extension axis can be inclined by a maximum of approximately 20°, preferably a maximum of approximately 10°, with respect to a normal on the extension axis; can therefore extend in a cone of 20° or 10° around the normal (longitudinal).
  • connection terminal described above makes it particularly easy to contact the connection terminal with contact pins (for example on a circuit board) by simply plugging it in, while at the same time the functionality of the connection terminal for providing through-wiring is retained due to the conductor insertion channels pointing away from each other. Since a clamping contact for receiving a contact pin is also provided in the connection terminal, contact pins used for making contact can be provided beforehand on a corresponding component, such as a circuit board in particular, so that any temperatures for attaching the contact pins (for example by soldering) do not affect the connection terminal itself. In addition, a connection terminal that is as flat and therefore as compact as possible can be provided in this way.
  • All contact insertion channels or their further extension axes are preferably aligned parallel to one another.

  • the spring clamping elements of the same contact element can preferably be formed integrally with one another. This reduces the number of individual parts on the one hand and simplifies production and assembly on the other.

  • a simple and effective design of the integrally provided spring clamping elements can thus be made possible.

  • the contact insertion channels are preferably each viewed from the outside towards the associated contact clamping point along their extension axis at least in sections on one side of a first contact guide section of the associated contact frame and at least in sections on a side opposite the one side by a second contact guide section of the associated contact frame.
