  • the invention has for its object to provide a further improved connection terminal.
  • Such a conductor terminal can be provided with extremely little effort, since it can be implemented with very few components.
  • such a connection terminal can be realized without the busbar known from other conductor connection terminals.
  • the first and second electrical conductors are not each connected to a busbar piece, as is the case in the prior art, but rather can be clamped together directly at the conductor clamping point in the connection clamp according to the invention, ie directly in mechanical and electrical contact to be brought.
  • the first and the second conductor routing channel are thus at least in the open enough at the conductor clamping point that the electrical conductors can be brought into direct contact with one another.
  • the first conductor routing channel and/or the second conductor routing channel can advantageously be formed from the material of the housing, for example formed in one piece with one or more housing parts of the housing.
  • the housing can advantageously be designed as an insulating housing, i.e. consist of an insulating material, e.g. a plastic.
  • the first conductor routing channel and/or the second conductor routing channel can be formed as a continuous channel or as a channel with one or more interruptions.
  • the connecting clamp can also be designed to connect more than two electrical conductors to one another.
  • the connection terminal has one or more additional conductor routing channels.

  • the connecting terminal has at least one metal clamping spring, by means of which the first electrical conductor and the second electrical conductor can be clamped together at the conductor clamping point.
  • This allows a reliable, durable electrical connection that can be established quickly between the first and the second electrical conductor.
  • the conductor clamping point is closed automatically by the spring force of the clamping spring.
  • the first and second electrical conductors are then pressed against one another by the clamping spring.
  • the clamping spring can consist of a suitable spring steel, eg chrome-nickel steel.

  • the clamping spring is arranged completely or at least predominantly within the housing.
  • the electrically conductive elements of the connec tion terminal can be well insulated and protected from unwanted contact who the.
