An electrical assembly may include a contactor, a bus bar connected to the contactor, a bracket connected to the bus bar, a flexible circuit electrically connected to the contactor, and/or a cooling member connected to the bracket. A method of assembling an electrical assembly may include disposing a flexible circuit at least partially on and/or in the bracket, connecting a bus bar with the one or more contactors, connecting the bus bar with the bracket, electrically connecting the flexible circuit to the one or more contactors, disposing a cooling member on or about the bracket, and/or connecting the cooling member with the bracket.

Provided is a circuit structure with a new structure that can improve a heat dissipation efficiency of a heat generating component while having resistance to a reaction force of a thermally conductive member. Provided is a circuit structure including: a heat generating component; bus bars that are connected to connection portions of the heat-generating component; cases that accommodate the heat-generating component and the bus bars; an elastic thermally conductive member that comes into thermal contact with the bus bars; a pressing portion that is provided on the cases and brings the bus bars into contact with the thermally conductive member; and a reinforcing wall portion that protrudes outside of the cases and reinforces the pressing portion.

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.

The present disclosure provides a circuit assembly that has a novel structure, with which it is possible to prevent the occurrence of a problem caused by an excessive repulsive force of a heat conductive member by controlling the repulsive force of the heat conductive member. A circuit assembly includes: a heat generation component; bus bars that are connected to connecting portions of the heat generation component; an insulating base member that holds the heat generation component and the bus bars; and an elastic heat conductive member that is in thermal contact with the bus bars. The bus bars press the heat conductive member in a mounting direction in which the bus bars are mounted on the base member. As a result of the bus bars abutting against bus bar positioning portions provided on the base member, the positions of the bus bars in the mounting direction are defined.

The present disclosure relates to a frame of an electromagnetic contactor, and more specifically, to an electromagnetic contactor having excellent coupling force between an arc box and a frame. The electromagnetic contactor, comprises: a lower frame; an upper frame coupled to the upper portion of the lower frame; and an arc cover coupled to the upper portion of the upper frame, wherein a first coupling part, is protrudingly formed on one surface of the lower frame, a second coupling part, connected to the first coupling part is protrudingly formed on one surface of the upper frame, and a third coupling part, connected to the second coupling part is protrudingly formed on one surface of the arc cover, wherein the fastening member is fastened by connecting the first coupling part, the second coupling part and the third coupling part.

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.

An electromagnetic relay including: a relay body that includes a first terminal; a base that includes a second terminal which contacts the first terminal and supports the relay body; an outer cover that covers the relay body; and an elastic member that is attached between the relay body and the outer cover.
