摘要： A continuous strip method for producing an electric strip laminate which is wound into a coil is proposed in which at least two electric strips are pressed against each other on their flat sides and are integrally bonded to form an electric strip laminate and in a further step, this electric strip laminate is wound into a coil. More particularly, a first electric strip is coated on at least one of its flat sides with a first thermally activatable hot melt adhesive lacquer, the first hot melt adhesive lacquer on the first electric strip is thermally activated, and then the electric strips are pressed against each other on their flat sides with the activated first hot melt adhesive lacquer layer between these flat sides and a second electric strip is supplied to this pressing process at a temperature below the activation temperature of the first hot melt adhesive lacquer layer on the first electric strip.

摘要： A compression housing for a laminate core of an inductive current transformer is disclosed herein. The laminate core may include a portion wound with a secondary winding. The laminate core may be housed in the housing operable between opened and closed configurations. The compression housing may include contact plates for providing an electrical contact to the laminate core in closed configuration. The compression housing may include compression wedges to provide compression to the laminate core between the compression wedge and the contact plate. The current transformer may be used to obtain electric power and electric current measurements from a primary conductor.

摘要： A coil component includes a core including a winding core portion and a first flange portion that is disposed on a first end portion of the winding core portion in a direction in which the winding core portion extends. A first curved portion is formed at a connection between a bottom surface of the winding core portion and the first flange portion. A ratio of a length of the first curved portion in a height direction to a distance in the height direction between the bottom surface and a first terminal electrode is no less than 20% and no more than 60% (i.e., from 20% to 60%).

摘要： A preparation method for a metal matrix composite wire includes the following steps: 1) preparing a metal inner core; 2) preparing a glass-resin mixture; 3) dissolving self-adhesive resin in a solvent to prepare a self-adhesive resin solution; 4) uniformly coating the glass-resin mixture on a surface of the metal inner core, then coating the self-adhesive resin solution on a surface of the glass-resin mixture, and performing drying at a temperature of 80° C. to 150° C.; and 5) repeating the step 4) until a thickness of the glass-resin mixture plus the self-adhesive resin reaches 2 to 10 μm. When an inductor is prepared by using the composite wire, the inductor may have relatively good weather resistance, a relatively good dielectric voltage-withstand capability, as well as relatively good high-temperature resistance and electrical performance.
