Abstract: The present invention provides a contact with low impedance even in a high frequency band. The contact (1) includes a base part (3), a contact part (5), and a spring part (7). The spring part (7) is elastically deformed to bias the contact part (5) in the x-axis positive direction and the z-axis positive direction. The contact part (5) includes a sliding part (23A) oriented in the x-axis positive direction. The base part (3) includes a part to be slided (14) oriented in the x-axis negative direction. The contact part (5) is biased in the x-axis positive direction by the spring part (7), so that the sliding part (23A) is in pressure contact with the part to be slided (14). The contact part (5) is configured to be slidable in the z-axis direction relative to the base part (3) while maintaining a state in which the sliding part (23A) is in pressure contact with the part to be slided (14).

Abstract: The present invention provides a contact capable of suppressing an increase in a DC resistance value for a long period and a method of manufacturing the same. The contact includes a base portion and an elastic contact portion. The elastic contact portion includes a planar portion configured in a planar shape; and a projection portion that is disposed on one surface of the planar portion and protrudes from the one surface. The elastic contact portion is configured to come into pressed contact with the second surface at the projection portion. The projection portion is configured such that a dimensional ratio H/L of the height H to the length L satisfies 0.25≤H/L≤0.44, where H is a height in a direction perpendicular to the one surface and L is a length in a direction parallel to the one surface.

Abstract: A contact includes a base portion fixable to a first member, a contact portion configured to make contact with a second member, and a spring portion configured to displaceably support the contact portion. The base portion, the contact portion, and the spring portion are integrally formed with a thin plate made of metal. The contact portion includes a flat plate portion extending in a flat plate shape from one end of a bent portion, and a protrusion protruding toward the second member is provided on the flat plate portion. The protrusion is provided at a location separated from a boundary between the contact portion and the spring portion by greater than or equal to 0.9 mm toward the contact portion.

Abstract: [Object] To provide a contact that can hold down effects caused by solder, even if an elastic contacting portion is extending from a location contacting a first member. [Solving means] The contact includes a base portion, an elastic contacting portion and a gap forming portion. The base portion is configured solderable on a component mounting surface of the first member. The elastic contacting portion is configured elastically deformable and relatively swingable with respect to the base portion, and when contacting a contacted surface of the second member, is configured to elastically deform to be in pressurized contact with the contacted surface. In the gap forming portion, a concave portion is provided between a first end portion and a second end portion, and is configured to have a gap between the concave portion and the component mounting surface when the base portion is soldered on the component mounting surface in a state in which the concave portion and the component mounting surface are oriented in directions facing each other.

Abstract: A clip is provided with a base portion, at least one holding portion, and a guiding portion. The holding portion includes spring pieces including a first and second spring pieces connected to the base portion and facing each other, and sandwiches an insert inserted between these spring pieces. The guiding portion includes a contact surface that guides the insert toward a position between the first and second spring pieces when the insert moves in an insertion direction and the guide portion comes into contact with the insert. The contact surface is at least partially in a position farther away from the base portion than the second portion of at least one of the first or second spring pieces. The contact surface is at least partially, in relation to a facing direction, in a position farther away from the corresponding spring piece than the second portion of the one spring piece.

Abstract: A noise suppression member according to one aspect of the present disclosure includes: a first core part and a second core part; and a first case part and a second case part. The first case part and the second case part are provided with engagement mechanisms. The engagement mechanisms each include an engaging portion and an engaged portion and is configured to fix the first case part and the second case part by engaging the engaging portions with the respective engaged portions. When the first case part and the second case part are fixed with the engagement mechanisms, the first core part and the second core part are maintained in a state of forming an annular magnetic core. When the engaging portion engages with the engaged portion, the first core part and the second core part are configured to come into contact with each other.
