An electrical component assembly suitably prevents electrical components from coming off, while adopting a simple structure of connection by a connection terminal to a control board. The electrical component assembly includes a housing in which the electrical components are assembled, and the electrical components and the housing are fixed to a surface of a base body. The electrical component includes a connection terminal to be press-contacted into a through hole of a substrate of the housing. The electrical component is provided with an electrical component adhesion margin facing said surface of the base body, so as to be fixed to the base body by an adhesive interposed between the base body and the electrical component adhesion margin.

An electromagnetic actuating apparatus having an armature unit (14) which can move along an axial direction (10) in response to current applied to a stationary coil unit and designed to interact with an actuating partner, wherein the coil unit has a winding (22) with which a connection contact (26) can make contact. The coil unit is accommodated in a housing (12) which surrounds the coil unit at least in sections. The coil unit has an electrical connection for connecting the connection contact to a plug section (18, 20) on the housing. The connection contact (26), together with a flat end section (30) of the electrical connection, which is oriented parallel to the connection contact and is permanently connected to the connection contact, extends at least in sections parallel to the axial direction (10) or is angled out of a position of extent in this direction after connection, wherein the housing end region is axially opposite a housing outlet for the armature unit (14).

A method for manufacturing a magnetic core module in a magnetic head, the magnetic core module and the magnetic head. The method for manufacturing the magnetic core module includes: a process for placing a magnetic core group in a holder mold cavity as an insert; and a process for injection-molding in the holder mold cavity. A method for manufacturing the magnetic core module allows the magnetic core group and the holder to be integrally injection-molded with a method of injection molding which uses the magnetic core group as an insert. The method simplifies the process of manufacturing a magnetic head to improve production efficiency, and saves labor and production costs. Further, the method prevents failures such as positional displacement and scattering of magnetic cores, which tends to occur when assembling thin and small magnetic cores, and ensures an ideal yield for a product.

A solenoid is provided with a valve body having a cylindrical shape extending along a front-rear direction, and a device connector including leg portions projecting outward from a side wall of the valve body and a connector housing provided on sides of the leg portions opposite to the valve body with a clearance provided between the side wall of the valve body and the connector housing, and a magnetic shield member made of metal, to be mounted outside the valve body and having a tubular shape open on one end part. The magnetic shield member includes avoidance recesses formed into a concave shape from an opening end to avoid interference with the leg portions and an inserting portion to be inserted into the clearance between the side wall of the valve body and the housing.

An apparatus and method of making the apparatus, the apparatus including an optical component; an electromagnetic microactuator configured to deflect the optical component; and a substrate configured to support the electromagnetic microactuator, wherein in an undeflected state the electromagnetic microactuator is configured to support the optical component above a plane of the substrate, and wherein the electromagnetic microactuator is configured to deflect from the undeflected state, to deflect at least a portion of the optical component towards the plane of the substrate without the portion of the optical component intersecting the plane of the substrate.

An electromagnetic actuator. The electromagnetic armature includes: an armature movable in an axial direction in an armature space; a magnetic coil for generating a magnetic field to move the armature; an operating element motion-coupled to the armature; and a flux-directing part, disposed at an axial end of the magnetic coil, having a recess which extends in the axial direction and in which the operating element is displaceably disposed, the flux-directing part being embodied in two parts. The flux-directing part is embodiment in two parts from a base part facing toward the armature and a top part facing away from the armature. The operating element is mounted, displaceably in the axial direction, in a first bearing point embodied on the top part and in a second bearing point embodied on the base part.

[Object] To provide a coil device, which is small and can be easily attached to various apparatus without providing a lead wire and can be easily and inexpensively manufactured, and a method for manufacturing the coil device, and a bobbin for coil which is used in the coil device and the method.

[Solution] The bobbin for coil 1 according to the present invention is for winding a conductor wire configuring an electromagnetic coil, and contains a first bobbin body 2, a second bobbin body 3 disposed in series to the first bobbin body 2, and a connecting part 4 coupling the first bobbin body 2 and the second bobbin body 3 in series.
