Definitions

  • the invention relates to a plug according to the preamble of claim 1.
  • Plugs are known, which are intended to connect high power devices, such as chargers for electric vehicles, to a low voltage grid. Due to the increasing spread of electromobility and the need to charge electric vehicles at home by means of a connectable to the household network charger, there is an increasing demand for such plugs. Due to the high connection power for a low-voltage network, charging may generate heat on the plug. This heat development can be monitored by means of temperature sensors, so that in the event of excessive heat generation of the charging current can be reduced to prevent damage to the plug, which could lead to electrical accidents or fire. The integration of temperature sensors in a plug is connected here for safety reasons with high restrictions.
  • the circuit with the mains voltage and the sensor circuit whose supply voltage makes up only a small fraction of the mains voltage, are electrically reliably separated from one another.
  • This can be done for example by the use of electrically insulating shrink tubing, with which the sensor circuit is isolated from the circuit with the mains voltage.
  • a good thermal contact between the contact pins and the temperature sensors is required so that a temperature rise can be detected quickly enough.
