Definitions
- the present invention relates to an airtight terminal used for a high capacity relay and a relay contact device using the airtight terminal.
- HEV hybrid cars
- RV vehicles The development of electric vehicles (hereinafter abbreviated as EV) is also active.
- HEV and EV require a large motor output, and the mounted battery has a high capacity.
- a high-performance high-capacity relay is indispensable for driving HEVs and EVs stably and efficiently.
- a high-capacity relay for in-vehicle use is required to be small and light because it is installed in a limited space. Further, in order to improve the energization performance of the relay, it is necessary to suppress the temperature rise during continuous energization as much as possible while using a low resistance metal for the energization portion. Furthermore, since it is a vehicle-mounted component, robustness and reliability that can withstand severe vibration and temperature load are also required (see Non-Patent Document 1).
- This electromagnetic relay includes an electromagnet device, a contact device, and a trip device.
- the electromagnet device includes a first excitation coil, a mover, and a first stator, and the mover is attracted to the first stator by a magnetic flux generated when the first excitation coil is energized. Is moved from the second position to the first position.
- the contact device has a fixed contact and a movable contact, and the movable contact moves with the movement of the mover, so that the movable contact comes into a closed state when the mover is in the first position.
- the mover is in the second position and in the third position, the movable contact is in an open state away from the fixed contact.
- the trip device has a second exciting coil connected in series with the contact device, and is generated in the second exciting coil due to an abnormal current exceeding a specified value flowing through the contact device in a state where the mover is in the first position.
