Definitions

  • the present invention relates to a relay, and in particular to a security relay equipped with a security function that allows the flow of current to a connected external circuit to be controlled depending on whether or not an external command to allow the relay to be energized is received.
  • a relay is a device that uses the passage of current through one terminal of a device as a trigger to control the flow of current through the other terminals, and is used, for example, to ensure safety when passing large currents and to ensure reliable operation.
  • security relays that not only control current flow but also have security functions have also come into existence.
  • This technology certainly makes it possible to provide a relay with many functions, but it is difficult to respond to abnormal situations such as unauthorized opening and closing of a contact device, and it is difficult to respond to unauthorized manipulation of an external circuit to which the relay is connected, so it cannot be said to be a sufficient technology from a security standpoint.
  • the security function of a relay is important because it makes it possible to cut off the flow of electricity and prevent unauthorized use, and is considered to be an effective function from a crime prevention perspective, as it protects devices that use relays, such as electronic components in automobiles, from unauthorized operation. Therefore, there has been a demand for the development of a security relay equipped with a security function that controls the flow of electricity to an external circuit depending on whether or not there is an external command to allow relay current to flow.
  • the security relay of the present invention is a security relay for controlling whether or not to energize an external circuit by an external signal
  • the security relay includes a control unit that receives a signal from the outside and analyzes the received signal, and determines whether or not to energize the external circuit based on the analysis result, and a power supply unit that supplies power to the control unit
  • the control unit includes a receiving unit for receiving a signal from an external device, and the receiving unit receives and analyzes a power permission signal from the external device to determine whether or not to energize the external circuit, and then performs the power supply process.
  • the security relay is a contact relay that includes an electromagnetic section having an electromagnet and a contact section that brings a movable contact into contact with or separates a fixed contact as current flows through the electromagnet.
  • the control section performs a current flow process that energizes the external circuit and energizes the electromagnetic section by receiving and analyzing a current permission signal from the external device using the receiving section.
  • the power supply section is configured to be connected to both the relay terminal on the electromagnetic section side and the relay terminal on the contact section.
  • the external circuit 20 is a circuit that controls the flow of electricity using a fuse or a switch. That is, the security relay 1 according to the present invention is configured to control whether electricity flows between the terminals of a fuse or through a switch.
  • the security relay 1 according to the present invention is configured to control whether electricity flows between the terminals of a fuse or through a switch.
