摘要： A relay unit includes a first busbar, a relay device, a second busbar, and a heat dissipation structure. The first busbar forms at least a part of an electric current path between a connecting portion, which is connected to a charging connector of an external charging device, and an in-vehicle battery. The relay device is provided on the first busbar. The second busbar forms at least a part of an electric current path between the in-vehicle battery and a power conversion device. The first busbar is branched at a branch portion from the second busbar, and includes at least a part of an electric current path extending from the branch portion to the connection portion via the relay device. The heat dissipation structure dissipates the heat from at least a part of the first busbar between the branch portion and the relay device.

摘要： The present disclosure discloses a specially packaged relay and a packaging method thereof. The relay includes an electromagnetic relay and an injection molded body. The injection molded body is injection molded outside the electromagnetic relay and wraps the electromagnetic relay therein. A plurality of conventional terminals of the electromagnetic relay are respectively exposed, or the conventional terminals of the electromagnetic relay are respectively located within the injection molded body, and each of the conventional terminals of the electromagnetic relay is connected with an external terminal that is exposed. The electromagnetic relay of the present disclosure is completely wrapped and sealed by the injection molded body, and is completely isolated from external liquid, which can effectively prevent the external liquid from flowing into the electromagnetic relay and ensure the electromagnetic relay to work stably for a long time in a liquid environment.

摘要： A high-voltage relay system for a vehicle is provided. The system includes a relay, a first contact part positioned between a battery and a power converter, a voltage application unit, and a second contact part positioned between the voltage application unit and the ground. A first resistor is connected, at a first end thereof, in series to a second end of the second contact part and connected, at a second end thereof, to the ground. A controller operates the relay in response to an ON/OFF control signal to short-circuit or open the contacts at both ends of the first contact part or the contacts at both ends of the second and determines whether the relay fails based on the type of the ON/OFF control signal and the voltage value between both ends of the first resistor.

摘要： An electromagnetic relay includes a base, a casing, a coil, a movable contact piece and two fixed contact pieces. Each of the fixed contact pieces includes a plate-shaped base. A portion of one side of the plate-shaped base extends outward and is bent to form a fixed contact fixing part. The fixed contacts are arranged on the fixed contact fixing part, and an abdicating through hole is defined in the base. The plate-shaped bases of the fixed contact pieces are respectively connected to an outer side surface of the base and spaced from each other. Each of the fixed contact fixing parts protrudes through the abdicating through hole and located between the base and the casing. Each of the fixed contacts faces to the movable contact on the movable contact piece, and a portion of the plate-shaped base on the fixed contact piece protrudes out of the casing to form a connecting part.

摘要： A contact device of the present disclosure includes a fixed terminal, a movable member, a regulating member, and a heat transmission structure. The fixed terminal includes a fixed contact. The movable member includes a movable contact and is configured to move between a closed position where the movable contact is in contact with the fixed contact and an open position where the movable contact is apart from the fixed contact. The regulating member is configured to be in contact with the movable contact when the movable member is in the open position. The heat transmission structure is configured to transmit, to the fixed terminal, heat from the movable contact when the movable member is in the open position, through a thermal path including at least the regulating member.
