Definitions

  • the invention relates to a connection of a conductor wire to a terminal piece and to a method for producing such connections according to the preambles of claims 1 and 2.
  • the object of the invention is to create a connection which is simple to produce and which is equivalent to a soldered connection.
  • a terminal piece 1 has a through bore 2 for receiving a conductor to be connected to the terminal piece 1.
  • wire 3 on. This can be the end of any electrical conductor.
  • the type of connection described below is advantageously used for electricity meters in order to connect their current coils, consisting of a conductor wire 3 with a rectangular cross section, to the terminal piece 1.
  • the conductor ends are to be rectangular, at least over the length serving for the connection, for example by squeezing.
  • the bore 2 has the same diameter over its entire length, while in the sectional drawings of FIGS. 2 to 5 the bore 2 merges into a bore 4 of larger diameter outside of a length L (FIG. 2) claimed for the connection with the conductor piece .
  • the larger bore 4 serves for the connection of one or more wires which can be clamped by means of two threaded holes 5 (FIG. 2) in the terminal piece 1 by screws, not shown, while in the smaller bore 2 in the finished connection the conductor wire 3 accordingly 1, is compressed like a harmonica in the form of a leporello stack.
  • the conductor wire 3 to be connected is inserted into the bore 2 and held outside the terminal piece 1 with two clamping jaws 6.
  • the depth of penetration V of the conductor end 7 into the terminal piece 1 depends on the desired package thickness S (FIGS. 1 and 5) of the finished connection and is to be determined by tests.
  • the conductor wire 3 should be guided with a little play over the entire length of its penetration depth V in the bore 2. If the bore 2 widens to a larger bore 4 (FIGS. 2 to 5), then the conductor wire end 7 penetrating into the bore 4 is to be guided in a guide sleeve 8 of the same inner diameter as the bore 2 during the crimping process, because otherwise it would dodge the wire end 7 laterally.
  • the conductor wire 3 bends on the long side of its rectangular cross section I of multiple, as shown in Figures 3 to fifth
  • the friction between the conductor wire 3 and the wall of the bore 2 in the harmonica-like together. pressing leads to local friction welding, the connection quality of which can be equated to a soldered connection.
  • clamping piece 1 In order to have the clamping piece 1 in an almost tension-free state after the crimping process, it is advantageous if the outer sides of the clamping piece 1, at least along the bore 2 having the finished connection, are enclosed by clamping jaws 11 (FIG. 2) during the upsetting process. These press the clamp piece 1 together and counteract the transverse forces generated during the squeezing process, so that only small internal stresses remain in the clamp piece 1 of the finished connection. This is important to avoid stress corrosion cracking if the clamp piece 1 is made of brass and is inserted into an embedding made of ammonia-containing molding compound.
  • Paint-insulated conductor wires can be used for the connection. It has proven to be advantageous if, when the wire is cut to length, its ends 7 are cut on the narrow sides to the length of the depth of penetration V. The resulting sharp edges and the side cutting away of the insulating layer of the conductor wire create a good starting point for cold welding during upsetting. Furthermore, by cutting on the side, a conductor wire 3 of larger cross-section can also be connected to the same terminal piece 1, it having been shown that the resulting reduction in cross-section has no disadvantageous effect.
  • connection described allows both copper and aluminum conductor wire to be used, and there are reliable, uniform series-produced connections of low electrical resistance and high thermal and mechanical stability.
