  • Electrical clamp connector and connecting terminal
    Patent number: 7384319
    Abstract: The invention relates to an electrical clamp connector and connecting terminal that, per pole, has at least two conductor terminal connections oriented in the same direction and an additional connecting contact on the opposite-lying side, which serves for connecting a countercontact external to the terminal. It is proposed for such a terminal to use the especially small-construction design features of a terminal that is produced from a single piece of spring steel sheet and a busbar rod, and to combine these with the new features that the busbar rod has one or two cross projections, which project through the free opening in the spring steel sheet and form the additional connecting contact, which, for example, may be constructed in the form of a socket contact or in the form of a plug-in contact.
