Abstract: In a method and a device for winding an acentric coil former, the coil former is set into a rotary motion with a winder drive, wherein the rotary motion of the coil former causes a wire attached to the coil former to be wound onto the coil former and unwound from a drum operatively connected to a brake drive, and the winder drive or the brake drive, or both, are controlled based on a rotation position of the coil former. The wire is unwound from the drum with a non-constant speed.

Abstract: A wire-wound electronic component, a core for a wire-wound electronic component and a method for manufacturing a core for a wire-wound electronic component are provided. A winding core portion of a core of a wire-wound electronic component includes flanges at respective ends of the winding core portion, and project in directions perpendicular to an axial direction of the winding core portion. Concaves are positioned at corners formed of adjoining surfaces of the flanges that adjoin to the winding core portion and end surfaces of the flanges that are located at ends in a first perpendicular direction, which is one of the projecting directions of the flange. Connecting surfaces, which connect contact portions where the flanges contact with the winding core portion to the end surfaces, are at least part of inner peripheries of the concaves. All normal vectors of the connecting surfaces have components in the first perpendicular direction.

Abstract: A cord management system includes a strap. The strap has a first set of magnets attached to a first location on the strap and a second set of magnets attached to a second location on the strap. The strap also includes at least two modes of operation. In a first mode of operation, the first set of magnets is magnetically attached to the second set of magnets so that a first segment of the strap located between the first set of magnets and the second set of magnets forms a loop configured to secure a cord that is wrapped around the strap. In a second mode of operation, the first set of magnets is magnetically detached from the second set of magnets so that the first segment no longer forms the loop. The strap is also configured to be coupled to an object.

Abstract: A method for manufacture of a conductor assembly. The assembly is of the type which, when conducting current, generates a magnetic field or in which, in the presence of a changing magnetic field, a voltage is induced. In an example embodiment one or more first coil rows are formed. The assembly has multiple coil rows about an axis with outer coil rows formed about inner coil rows. A determination is made of deviations from specifications associated with the formed one or more first coil rows. One or more deviations correspond to a magnitude of a multipole field component which departs from a field specification. Based on the deviations, one or more wiring patterns are generated for one or more second coil rows to be formed about the one or more first coil rows. The one or more second coil rows are formed in the assembly. The magnitude of each multipole field component that departs from the field specification is offset.

Abstract: Traditional methods of making headlamp coils have left a portion of the coils with slightly irregular forms. These irregularities can result in defects in the ultimate beam pattern. Accommodating these defects in robust lamp and headlamp optical systems can reduce the performance that might otherwise be available. The preferred coil is therefore continuously coiled as a straight body, and carefully cut into segments. Subsequently, legs are welded to the coil segment ends. The coil is then left substantially undistorted by the manufacturing process that would otherwise normally leave a portion of the coils distorted. The method particularly enables a functional center leg coil.

Abstract: A method of manufacturing a coil having a cross section differing from a circular ring cross section. In this method a circular cylindrical coil with a circular ring cross section is first wound and then reshaped into a coil with a cross section differing from the circular ring cross section. At least two axially parallel fingers of an expander are temporarily inserted into the coil interior for reshaping the wound circular cylindrical coil and are displaced in a diverging relative movement after the insertion and while doing so expand the initially circular cylindrical coil into the coil having the different cross section.

Abstract: A conductor wire material CW is wound into an accurate size without causing floating and deformation when an electric coil is formed. When the conductor wire material CW supplied from a wire material feed portion 3 is wound by turning a coil-winding mold 4 and is processed to fabricate an electric coil having a desired coil shape, the coil-winding mold 4 is linearly moved in a direction D away from the wire material feed portion 3 by a distance corresponding to a major side portion 40a to impart predetermined tension to the conductor wire material CW when a winding portion 40 of the coil-winding mold 4 on which the conductor wire material is wound is the major side portion 40a, and the coil-winding mold 4 is rotated when the winding portion 40 of the coil-winding mold 4 on which the conductor wire material is wound is a minor side portion 40b.

When the coil is wound, the former is disassembled and the end portions are pulled towards the center of the former and turned through 90° to be removed. A method of using the former is described.

Abstract: A bobbin for an electrical coil having a width that is small with respect to its depth. The bobbin is constructed from two identical halves, each having one generally flat flange and a web portion defining a latching feature, a locking feature and a core window centrally located in the flange. The mating surfaces of the two bobbin halves are defined along the distal ends of the web portions such that each half includes one complete flange and core window. The mating surfaces are also configured such as to prevent the fine coil wire from slipping between the mating surfaces of the two bobbin halves as the coil is being wound. The latching features of one bobbin half slidingly engage the latching features of the other bobbin half such that the two bobbin halves are held together. The locking features of the two bobbin halves also engage to prevent unintentional longitudinal movement between the two bobbin halves prior to winding the coil wire on the bobbin.
