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 invention has for its object to provide a simple connection that is equivalent to a soldered connection.
- a terminal piece 1 has a continuous bore 2 for receiving a conductor wire 3 to be connected to the terminal piece 1.
- This can be the end of any electrical conductor.
- the type of connection described below is used in electricity meters 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 hole 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 clamping piece 1 by screws, not shown, while in the smaller hole 2 in the finished connection the conductor wire 3 corresponds to the figure 1, is compressed like a leporello stack.
- 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 position for a calf welding during upsetting. Furthermore, by the side cutting also a conductor wire 3 of larger cross-section can be connected to the same terminal piece 1, it having been shown that the resulting reduction in cross-section has no adverse effect in any way.
- 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.

5. Procédé suivant l'une des revendications 2 à 4, caractérisé en ce que, pendant l'opération d'acrasement, l'extrémité (7) du fil conducteur pénétrant avant le refoulement dans un perçage (4) de plus grand diamètre, est guidé par un fourreau de guidage (8) de mëme diamètre intérieur que le perçage (2) servant pour le raccordement.
6. Raccordement suivant la revendication 1, caractérisé par l'utilisation dans un compteur d'électricité pour la connexion des extrémités (3) de la bobine ampère-métrique à une borne ( 1 ) respective.
7. Raccordement suivant la revendication 1, caractérisé en ce que le fil conducteur (3) est en cuivre ou en aluminium.
8. Raccordement suivant la revendication 1, caractérisé en ce que le rapport de la largeur à la hauteur de la section rectangulaire sur la longueur de la profondeur de pénétration (V) du fil conducteur (3) est compris entre 5:1 et 2:1 et en ce que le diamètre du perçage correspondant (2) est supérieur d'environ 2 à 10% à la diagonale de la section rectangulaire.
