  • Patent number: 10825596
    Abstract: A laminated electronic component includes an element body and a pair of conductors. The element body is formed by laminating a plurality of element-body layers in a first direction. The pair of conductors is formed by laminating a plurality of conductor layers in the first direction. The pair of conductors is provided to the element body in such a way as to be separated from each other in a second direction orthogonal to the first direction. At a cross section orthogonal to the first direction, the pair of conductors has an uneven portion and the element body has an uneven portion engaged with the uneven portion of the pair of conductors.

  • Publication number: 20190386417
    Abstract: A connector which can improve reliability of electrical connection is provided. Accommodation recesses are formed to a plate-like terminal member, and a coil member accommodated in the accommodation recesses is retained to the terminal member, thereby allowing wire winding portions of the coil member to be deformed within the accommodation recesses when the winding wire portions are sandwiched between bottom faces of the accommodation recesses and a mating terminal. Consequently, the obliquely wound coil member is not likely to experience deformation other than fall over of ring portions, and/or is not likely to be displaced, improving contact between the coil member and both of the terminal member and the mating terminal. As a result, reliability of electrical connection can be improved.
