Abstract: An energy management method is provided for detecting an energy consumption of at least one consumer connected to an energy supply network, wherein relevant detection values of each energy consumption are detected by a plurality of detection devices and/or calculated from detected values. A switching device is respectively assigned to at least one of the detection devices and/or at least one group of the detection devices. The detection values detected and/or calculated by the detection device and/or the group of detection devices are each provided to the switching device according to a predefined detection device protocol for the detection device and/or the group of detection devices. The respective energy values are transmitted to a central device via a network which connects the central device to all switching devices, according to a predefined central device protocol which differs from the detection device protocol.

Abstract: An electrical signal connector which is interposed between an electronic device and an electrical signal cable, which is used for an electrical signal which is output from the electronic device or an electrical signal which is input into the electronic device, and which has an electrical signal cut-in terminal, an electrically conductive plate and at least one metal cable clamp. At the time of installation of the electrical signal connector, electric wire connectors in the electrical signal cable which communicate with the exterior are taken forwards along one surface of the conductive plate and extended together with conductive plate projecting terminals into accommodating electrical signal cut-in terminal ports of the electronic device, and, at the same time, the electrical signal cable and conductive plate are closely connected via the metal cable clamp, so fixing the electrical signal cable and conductive plate together, and ensuring that the cable connectors do not suffer damage.
