Definitions

  • the invention relates to a connecting terminal, for example for installation devices such as circuit breakers, in which a clamping screw is guided in a frame-like clamping body in a side wall of the clamping body, in detail according to the preamble of claim 1.
  • the clamping screw works clampable against an opposite side wall, a pressure piece is arranged in an imaginary connection level.
  • a bracket made of electrically highly conductive material is guided from the pressure piece next to the walls of the clamping body to a connecting plane (DE-A-2 642 262).
  • this is intended to make it possible to deliver the terminal in a consumer-friendly open state and still enable testing of the devices which are connected to the terminal even when the terminal is open.
  • Connection terminals such as those used in installation devices, usually form an electrical connection between conductors to be connected in the terminal and elements of an installation device located behind the terminal.
  • the designer has to meet opposing conditions: namely, on the one hand, to manufacture the connection terminal up to a connecting bracket from electrically highly conductive material and, on the other hand, to ensure greater mechanical stability.
  • the invention has for its object to develop a connecting terminal that meets the mechanical and electrical requirements in a particularly economical manner.
  • a connecting clamp according to claim 1.
  • a bracket made of electrically highly conductive material is next to the pressure piece Walls of the clamp body led to a connection level such that the bracket on the connection side for conductors to be connected runs edged to the connection level and there merges into an upright bracket area, in particular according to the characterizing features of claim 1.
  • the bracket rotates the clamp body at least partially and merges into a connection conductor on the connection side. This creates an electrical transition from a connection level to a higher connection level without being dependent on the electrically conductive properties of the material of the clamping body itself.
  • the electrical connection between the pressure bracket and the connection conductor is achieved in the clamping body by the clamping screw on the pressure bracket working against the adjacent wall.
  • a clamp with a movable pressure piece is known (DE-PS-2 502 675), the pressure piece being actuated by means of a screw guided in the pressure piece upper part.
  • a hat-shaped driver is arranged between the screw head and the pressure piece upper part, which grips under the pressure piece upper part with its brim and rests with its hat body on the screw head, a passage through to the screw head being left open in the middle field.
  • the electrical connection of a conductor to be connected takes place between the clamping body and the pressure piece, the special construction allowing the clamping screw to be open for easier connection of conductors.
  • a connection to elements of a device is not addressed in its design. It can be produced in the usual way by means of brackets or rags for the clamping body.
  • a bracket made of electrically highly conductive material is guided from the pressure piece next to the walls of the clamping body to a connecting plane in such a way that hardly any space is required laterally next to the clamping body.
  • the electrical requirements can be met by choosing the ironing material and / or by its correspondingly wide design.
  • bracket on the connection side for conductors to be connected runs edged to the connection level and there merges into an edgewise bracket which at least partially rotates around the clamping body and which merges into the connection conductor on the connection side.
  • the bracket can be manufactured using simple stamping and bending technology and are connected to the connecting conductor by brazing.
  • the bracket can be guided around the outside of the clamping body by appropriate shaping or bending deformation in the manner of a screw line part.
  • the upright bracket part can be designed in the manner of a sleeve comprising the clamping body, to which the connecting conductor connects.
  • a particularly wide current-carrying cross-section is available and, at the same time, a mechanically stable holder is achieved for the bracket adjoining the pressure piece and for the connecting conductor.
  • the connecting conductor merges into an arc running rail for a stack of fire-extinguishing sheets.
  • the fixed contact for a circuit breaker can also be arranged on this arc running rail.
  • connection conductor 7 has a frame-like clamping body 1, in one side wall 2 of which a clamping screw 3 is guided. This works clampable against an opposite side wall 4, a pressure piece 5 being arranged in an imaginary connection plane. The pressure piece 5 goes into a bracket 6, likewise made of electrically good conductive material. The bracket is guided next to walls of the clamping body 1 to a connection level, in which it merges into a connection conductor 7.
  • the material and the shape can be chosen from the perspective of mechanical stability. With the bracket you are free to choose a material that meets the electrical requirements. Due to the flat course of the bracket 1, little space is required next to the clamping body. No space is required laterally next to the clamping body if the transfer of the bracket 6 to the connecting conductor 7 is carried out laterally next to the clamping screw within the base area of the clamping body.
  • the bracket 6 on the connection side for conductors to be connected extends or is bent up to the connection level; there it merges into an upright bracket area 8.
  • the bracket area 8 runs around the clamping body 1 at least partially, it merges into the connecting conductor 7.
  • the transition from the upright bracket area 8 to the connecting conductor 7 has been achieved by twisting bending.
  • the bracket 6 rotates the clamp body 1 in the manner of a portion of a helix.
  • the upright bracket area 8 is designed in the manner of a sleeve comprising the clamping body, to which the connecting conductor 7 is connected.
  • the connecting conductor 7 merges into an arc running rail 9.
  • Arc guide rail 9 can also be a fixed contact piece for a movable mating contact of a circuit breaker. Special material requirements can be taken into account in area 11 of the arc guide rail, to which quenching plates can be adjacent to a quenching chamber. Transition points between different materials can be realized by known connection techniques, for example by brazing.
