  • Patent number: 11118651
    Abstract: A connector includes a first buffer member that includes a spiral-shaped wire, a second buffer member that has a substantially annular and flat plate-like shape capable of warping in a thickness direction, a collar member that includes a first flange facing a radially inner side of the first buffer member, and a second flange facing a radially inner side of the second buffer member, and a coupling member. A gap for allowing the second buffer member to move in a radial direction is formed between the second buffer member and a cylindrical portion. A distance between a position of a surface of the second flange and a position of a lowest end of the collar member is greater than a distance between a position of a surface of the first flange and the position of the surface of the second flange in a view in an axial direction.

  • Publication number: 20200391269
    Abstract: Provided is a shield molding blank which has an uneven structure in which an air gap 4 is formed between metal plates 2, 3 formed in overlapping wavy shapes comprising recesses and projections that are periodically continuous in two directions orthogonal to each other, the shield molding blank being cut in a desired expanded shape and having peripheral edges folded. With the shield molding blank, it is possible to mold a shield having improved shield characteristics such as a heat-shielding property and a sound-shielding property.

  • Patent number: 10753423
    Abstract: A connector (1) that comprises first and second surfaces (20a) and (30a) disposed opposingly with an interval therebetween, said interval allowing the shielding body 100 to be inserted therein; a pressing member (4) having a through hole (40) and formed so as to be capable of extending and contracting by winding a prescribed wire material spirally around the through hole (40) as center such that a curvature thereof varies continuously around the through hole; and a holding part (31) that is inserted into a hole (103) formed in the shielding body and the through hole (40) and maintains a specific distance between the first and second surfaces (20a, 30a); wherein the pressing member (4a) and (4b) comprises: a first pressing member (4a) disposed between the first surface (20a) and the shielding body (100) such that a small-curvature side thereof in the extension and contraction direction faces the shielding body (100); and a second pressing member (4b) disposed between the second surface (30a) and the shielding

  • Patent number: 10494978
    Abstract: Provided is a shield in which a flexible member is interposed between two metal plates; still unfilled spaces that are not filled with the flexible member are secured, so that the shielding properties are improved by air layers. The shield 1A includes two metal plates 2, 3 disposed to face each other, and a plate-shaped flexible member 4 interposed between the two metal plates. Each of the two metal plates 2, 3 has a plurality of protrusion-depression structures. Gap-forming means is provided to form gaps of a width greater than the thickness of the flexible member 4 between the two metal plates 2, 3 when the flexible member 4 is interposed therebetween. Unfilled spaces (5) that are not filled with the flexible member 4 are provided between the two metal plates 2, 3.
