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.

Systems, devices, and methods for an electrical switch including: an enclosure; a hinged armature disposed within the enclosure; a moveable contact electrically coupled to the hinged armature and disposed substantially parallel to the hinged armature; and a rib positioned between the hinged armature and an outer edge of the electrical switch, where the rib transfers external forces applied to the electrical switch to the enclosure by limiting movement of the hinged armature towards an outer edge of the electrical switch.

An electronic component includes a component main body having a rectangular parallelepiped shape and a plurality of lead terminals, and each lead terminal is disposed to droop along a side surface of the component main body facing the lead terminal. The plurality of lead terminals having different rigidities are arranged in a width direction of at least one side surface of the component main body, and the lead terminal having a highest rigidity among the plurality of lead terminals is disposed to protrude more in a direction in which it gets apart from the corresponding side surface of the component main body than the other lead terminals. Accordingly, it is possible to prevent deformation of the lead terminal.

A contact device includes a moving contactor, a pair of moving contacts arranged in one direction, a pair of fixed terminals, and a pair of fixed contacts. At least one fixed terminal, selected from the pair of fixed terminals, includes a contact holder. The contact holder includes a first fixed extension and a second fixed extension. As for either a current component flowing in the one direction into the fixed contact or a current component flowing in the one direction out of the fixed contact, the current component flowing through the first fixed extension has a larger amount of current than a current component flowing through the second fixed extension.

An electromagnetic relay includes a fixed contact, a movable contact corresponding to the fixed contact, a movable element that retains the movable contact and moves in a contacting direction and a separating direction relative to the fixed contact, an axial core coupled to the movable element, a movable core coupled to the axial core to move in the contacting direction and the separating direction relative to a movement of the axial core, a driving part that drives the movable core in the contacting direction, an urging part that exerts force to the axial core in the separating direction, and a constraining part that constrains the relative movement of the axial core in the separating direction.

A relay device comprises a base, a pin, and an outer cap. A gap is arranged at a peripheral of the base. The pin has a convex plate and assembled to the gap of the base and one end thereof is protruded from the gap. The convex plate is covered/shielded the gap. The outer cap includes a receiving groove. A notch of the receiving groove is covered the base and the pin. A paste is applied among the peripheral of the base, the convex plate of the pin, and the notch of the receiving groove for fastening. The gap arranged at the peripheral of the base is providing the pin for assembling without directional limitation and advantageous to once assembly of the base and the pin in an automatic machine so as to simplify the manufacturing process of the relay device.

The fixed contact member includes a fixed contact. The movable contact member includes a movable contact and is movable between a position where the movable contact is in contact with the fixed contact and a position where the movable contact is away from the fixed contact. The permanent magnet forms a magnetic field around the fixed contact. The case is for accommodating at least the fixed contact member and the movable contact member. Further, the case includes an accommodation part which is partitioned from an internal space of the case and is for accommodating the permanent magnet through an opening thereof directed to an outside of the case.

Provided is a connection unit including an electromagnetic relay and a bus bar connected to the electromagnetic relay. In such a connection unit, a first bus bar connected to a first fixed contact terminal is disposed facing one surface of a movable touch piece located on an opposite side of the movable touch piece from the other surface of the movable touch piece in a contact-making and breaking direction, with a gap provided between the first bus bar and the movable touch piece in the contact-making and breaking direction, the first bus bar extends in a direction that intersects the contact-making and breaking direction and in which a first movable contact and a second movable contact of the movable touch piece are arranged, and at least part of the first bus bar lies over the movable touch piece in plan view in the contact-making and breaking direction.
