摘要:
An electromagnetic contactor (1a) is provided with an erroneous mounting prevention unit (8) which permits an entry of a connection piece when a connection piece (6f) of a reversible unit (6) attempts to enter a normal position (NP) inside a display window (3a) where the connection piece is connectable to an operation display piece (4a), and prevents the entry of the connection piece when the connection piece attempts to enter a position inside the display window (3a) deviated from the normal position (NP).

A voice-coil motor (VCM) with voice coils configured to reduce vibrations of a head when data is accessed on a disk in a disk drive. The VCM includes at least one VCM magnet and a voice-coil assembly. The voice-coil assembly includes a first voice coil and at least a second voice coil. The first voice coil is disposed in proximity to a magnetic pole of the at least one voice-coil-motor magnet. The second voice coil is disposed in close proximity to the first voice coil such that the first voice coil substantially overlays the second voice coil. The first voice coil and the second voice coil are configured to reduce vibrations of the head when data is accessed on a disk in the disk drive. A rotary actuator including the voice coils and a disk drive including the VCM are also provided.
摘要:
A mounting unit for an electromagnetic contactor can prevent erroneous mounting of a non-mountable unit in a state in which a mountable unit is mounted on a case-side mounting portion, and a connection structure of an electromagnetic contactor uses the mounting unit. A mounting unit (3) for an electromagnetic contactor can be mounted on electromagnetic contactors (2a, 2b) having on a unit attaching portion (6b) a contactor-side mounting preventing portion (6f) that prevents mounting by engagement when a non-mountable unit, which cannot be mounted, is mounted. In the mounting unit (3), a unit main body (39) is provided with a mounting preventing transfer member (51) that forms a unit-side mounting preventing portion (54) that engages with a contactor-side mounting preventing portion (6f) when mounted on the electromagnetic contactors (2a, 2b) and prevents mounting of the non-mountable unit on a unit mounting portion (3g) onto which the non-mountable units (5a, 5b) are mounted.

The electromagnetic contactor enables a reliable return to a pole open position without increasing the spring force of a return spring. In an electromagnetic contactor, an electromagnetic device having an exciting coil and a contact mechanism having a return spring are disposed in parallel, and the electromagnetic device and contact mechanism are linked by a drive lever. The electromagnetic device has a polarized electromagnet having a magnetic circuit that includes a permanent magnet generating a suction force that moves the contact mechanism to a pole open position side when the exciting coil is not energized. The drive lever is fixed to either one of the electromagnetic device or contact mechanism and contacts with the other with no gap at least when the contact mechanism is moved to the pole open position side. The return force of the contact mechanism is covered by the suction force of the permanent magnet.

摘要:
An electromagnetic contact device has a terminal base (18) formed on one end of a coil frame around which a winding of an electromagnetic coil is wound; a terminal (20a) which can be connected to external wiring, and a winding wire binding portion (20e) which can bind an end portion of the winding, wound around the coil frame to establish connection. The coil terminal (20) is a component formed by integrating the terminal (20a), the winding wire binding portion (20e), and a portion to be engaged (20b). This coil terminal (20) is mounted by press-fitting a press-fit engaging portion (18b), which is formed in the terminal base (18), in the portion to be engaged (20b) to establish engagement.

First fitting portions (9a and 9b) and second fitting portions (9c and 9d) are arranged in a hook shape on the bottom (3a) of a housing to face each other. The first fitting portions are fittingly engaged to one rail edge (2a) of a rail (2) in the width direction and the second fitting portions are fittingly engaged to the other rail edge (2b) of the rail. A linear spring (10) bent in a mountain shape is disposed on the bottom of the housing. The linear spring elastically deforms to reduce the inclination angle of the mountain by contacting the end surface of the one rail edge engaged to the first fitting portions. The urging force of the linear spring urges the rail such that the other rail edge is pressed by the second fitting portions.
