A solenoid apparatus is combined with a printed circuit board to form an improved combination of structures. The solenoid apparatus includes a solenoid that is situated on a frame that is formed from an electrically nonconductive material. In another embodiment, a frame of a solenoid apparatus is modified to remove a dependent structure in order to avoid a frame from being soldered together with an electrical connector of a solenoid. In a third embodiment, a solenoid apparatus includes a frame having a protuberance that is situated at a location spaced equally from each of a pair of electrical connectors of the coil. In a fourth embodiment, a solenoid apparatus includes a frame with a protruding structure, but the protruding structure is spaced from a circuit board and thus does not become electrically connected therewith. A method is also disclosed.

A magnetic latching relay comprises a metal insertion portion of a contact portion and a slot of a base. The metal insertion portion is composed of two segments having different depth corresponding to the slot; when one segment is fitted to bottom wall of the slot, a preset gap is formed between the other segment and the bottom wall. The slot is formed by two segments having different thickness corresponding to the metal insertion portion; when two side walls of one segment of the slot are adapted to two sides of thickness of metal insertion portion, two side walls of the other segment of the slot and two sides of thickness of metal insertion portion respectively form a preset gap; one segment of metal insertion portions cooperates with the other segment of the slot, and the other segment of the metal insertion portion cooperates with one segment of the slot.

Provided is a tactile information supply module. The tactile information supply module includes a receiver for receiving message information from the outside, a controller for converting the message information into a tactile signal, and an operator for providing tactile information to a user based on the tactile signal, wherein the operator includes at least one tactile sensation provider comprising magnetic particles and a matrix material, and wherein the tactile sensation provider is transformed in response to an external magnetic field to provide the tactile information.

The present disclosure provides systems and methods for an electromagnetic actuator having a unitary pole piece arranged within and coupled to a housing. The electromagnetic actuator can include the housing, the unitary pole piece, an armature received within the unitary pole piece, and an end cap. The unitary pole piece is structured to provide a reduction in air gaps within the electromagnetic actuator.

An electric component assembly includes a housing with which an electric component is fitted together, and the electric component and the housing are fixed to one side of a base body. The electric component includes a connecting terminal configured to be press-fitted in a through-hole of the control board of the housing, and a direction in which the connecting terminal is inserted into the through-hole is same as a fitting direction relative to the housing. There are provided a rib protruding from one of the electric component and the housing, and a groove portion recessed from another one of the electric component and the housing and into which the rib is press-fitted. Movement of the electric component in a direction intersecting the fitting direction and rotation of the electric component around an axis parallel to the fitting direction are restrained by the rib press-fitted into the groove portion.

A solenoid actuator includes a housing assembly, a bobbin assembly, a coil, an armature, and an anti-rotation structure. The bobbin assembly is disposed at least partially within the housing assembly and includes a return pole and a yoke. The yoke has an inner surface that defines an armature cavity. The coil is disposed within the housing assembly and is wound around at least a portion of the bobbin assembly. The armature is disposed within the armature cavity and is axially movable relative to the yoke. The anti-rotation structure is disposed within the housing assembly and engages at least a portion of the armature. The armature and the anti-rotation structure each have at least one feature formed thereon that mate with each other and thereby prevent rotation of the armature.
