Definitions

  • the present invention relates to the field of low voltage built-in devices with switching, protection or signaling function. It concerns a low-voltage built-in device according to the preamble of claim 1 and a terminal family.
  • Circuit breaker which has an electronic evaluation unit instead of a bimetal, is known for example from DE 197 21 591 A1. This can be loaded with rated currents of up to 125 A and is equipped with connecting terminals for connecting connecting conductors with appropriately dimensioned conductor cross sections of up to 70 mm 2 .
  • the company Merlin-Gerin / Schneider Electric offers one under the designation NG125 Circuit breaker in modular device format, which via a flexible terminal change system features.
  • Different connection terminals for Copper conductors, aluminum conductors, ribbon conductors, cable lugs
  • openings of the Switch housing inserted and with an insertable terminal cover in the form fixed on an aperture.
  • the object of the present invention is to provide a low-voltage built-in device with a modular connection system for easy adaptation to different Specify connection conductor. This task is accomplished by a low voltage built-in device with the features of claim 1 and a terminal family with Features of claim 9 solved.
  • the essence of the invention is an insulating material carrier as part of the modular To provide terminal system, which can be used in the built-in device and a Clamping movement of the actual clamp leads.
  • This carrier will adapt to another type of connection conductor generally together with the terminal replaced. This results in greater flexibility and simpler Variant form.
  • the carrier By designing the carrier as an insulating body, the latter functions as a fifth also as a terminal cover, i.e. it will also be the first protection against accidental contact live conductor parts manufactured.
  • the clamping movement triggered by a clamping screw which is in a thread in the clamp is screwed in.
  • the carrier is equipped with a movable cover.
  • the insulating material carrier has a snap-in device or provided with a snap mechanism, which allow it to be detachably and Way to click or snap into the housing.
  • connection leads in a built-in device with a circuit breaker function Foreground namely a flexible or rigid, single or multi-wire conductor for direct connection or alternatively, a conductor provided with a cable lug indirect connection.
  • the clamp has the shape of a cage clamp, whereby the thread and the connecting conductor on opposite sides of one another contacting contact conductor and the cage clamp partially the two conductors surrounds.
  • the contact conductor with an opening which is the cable lug has a comparable diameter.
  • the cable lug comes in this case preferably to lie between the contact conductor and the connection thread of the terminal and the screw penetrates both the contact conductor and when the conductor is connected also the cable lug.
  • the insulating material carrier with a collar Mistake is the insulating material carrier with a collar Mistake.
  • a terminal family according to the invention comprises at least two terminal systems with the two main components of the bracket and the clamp.
  • Latter are easily interchangeable, i.e. is the change from a first system to a second possible in a few simple steps. Nevertheless, there is sufficient flexibility to Creation of new variants of connection terminal systems.
  • Fig. 1 a section of a low-voltage built-in device is shown, one of which End face for connecting a connecting conductor by means of an inventive modular terminal system (both not shown in Fig.1) is prepared.
  • Plastic housing 1 of the device forms a connection space 10 and has in the area this connection space 10 via a connection opening 11 for receiving the Terminal system.
  • a rigid contact conductor 2 protrudes into the connection space, which is brought into contact with the connection conductor and the electrical connection forms functional units inside the device and / or further connection points.
  • Terminal 4 in the form of a cage clamp is for connecting conductors or Strands provided without cable lugs.
  • a clamping screw 40 is in a thread in the Terminal 4 screwed, both together are mounted in the carrier 3 and with this inserted into the connection opening 11.
  • An insertion protector 41 in the form of a tongue blocks terminal 4 when terminal 4 is tightened.
  • the carrier 3 has an end surface 30, the circumference of which is the connection opening 11 of the housing 1 is simulated, so that the carrier 3 fits into the housing 1 can be used.
  • a movable cover 32 in the form of a lid allows access to the clamping screw 40, said cover 32 when the cover is closed Clamping screw 40 is protected against unintentional contact.
  • On the side of the carrier 3 attached receptacles 33 or tabs act with snap hooks in the housing 1 together and snap the carrier 3 into place.
  • connection system from FIG. 2 is mounted in the carrier 3 Terminal 4 shown from a different perspective, once without and once with Contact conductor 2 and connecting conductor 5. At least from the design of the terminal 4 partially surrounding carrier 3 it can be seen that the latter is only a movement of the Terminal 4 allows in the vertical direction.
  • the vertical freedom of movement of the Clamping screw 40 is through the internal contact conductor 2 or the carrier 3 itself limited, so that when the clamping screw 40 is turned, it is not the screw Terminal 4 moved in the vertical direction.
  • the clamping screw 40 in Moving clockwise, the terminal 4 and the connecting conductor 5 and the contact conductors 2 lying above are pressed together.
  • the clamp 4 shows an insulating material carrier 3 and a terminal 4 of a second terminal system shown. This is for the connection of connection conductors with cable lugs provided, and as protection against contact of a crimping point of the cable lug, the carrier 3 provided with a generously dimensioned collar 31. Again are one movable cover 32 and receptacles 33 available.
  • the clamp 4 has the shape a rectangular nut.
  • a clamping screw 40 only screwed into a thread of the clamp 4 when the Carrier 3 with terminal 4 installed in connection space 10 and on Cable lug inserted through an opening in the carrier 3 and with the clamp 4 in cover was brought.
  • contact conductors 2 and Cable lug each have a hole whose diameter is larger than that of Clamping screw 40.
  • FIG. 5 the variant of the cable lug with a mount in the carrier 3 is analogous to FIG Terminal 4 shown from a different perspective, both without and with Contact conductor 2 and connection conductor 5 including cable lug 51. Again, the one used Terminal 4 can only be moved vertically. When tightening the clamping screw 4 will be Cable lug 51 and contact conductor 2 pressed together.
