  • Patent number: 9852845
    Abstract: In order to provide an air core coil fitting apparatus that can automatically fit an air core coil onto a core, an air core coil fitting apparatus includes a holding member, a coil fitting rod, a rod driving member, a pushing member, and a sending member. The holding member holds a core main body that is formed in a ring shape, has a gap extending through the core main body from an inner circumferential face to an outer circumferential face thereof, and allows an air core coil wound in advance to be fitted onto the core main body from one end thereof. On the coil fitting rod, the air core coil that is to be fitted onto the core main body held by the holding member is fitted. The rod driving member brings a front end of the coil fitting rod close to or into contact with the one end of the core main body held by the holding member. The pushing member pushes the air core coil fitted on the coil fitting rod, toward the one end of the core main body.

  • Patent number: 9609756
    Abstract: A method includes aligning a first portion of a magnetic core with respect to a first side of a PCB using a first alignment device. The method includes applying a first bonding material to a surface of at least one of the first portion of the magnetic core and a second portion of the magnetic core. The method further includes coupling a second alignment device that retains the second portion of the magnetic core to the first alignment device. When the first alignment device and the second alignment device are coupled, the first portion and the second portion of the magnetic core are retained in a specified assembly position. The specified assembly position includes a specified gap between the first portion and the second portion of the magnetic core. The method also includes curing the first bonding material.

  • Patent number: 9530585
    Abstract: The invention relates to a switching device (10), in particular in a motor vehicle, having an adjustable touch-sensitive switching element (12) which is switchable by a touch pressure exerted in a direction (s) of actuation. The switching element (12) is adapted to assume a first initial position, in which the switching element (12) bears on an abutment (14) in the direction (s) of actuation. The switching element (12) is adapted to assume a second initial position, in which, compared with the first initial position, the switching element (12) is adjusted by a predeterminable travel (x1) contrary to the direction (s) of actuation.

  • Patent number: 9406469
    Abstract: An electromagnetic relay has a movable touch piece, a movable contact provided on the movable touch piece, and a fixed contact opposed to the movable contact. The movable touch piece is rotated by a movable iron piece that rotates based on magnetization and demagnetization of an electromagnet block, to make the movable contact come into contact with and separate from the fixed contact. Operation characteristics are made adjustable by a press-fitting amount at the time of press-fitting a fixed contact terminal provided with the fixed contact into a spool of the electromagnet block along a moving direction of the movable contact.
