摘要： In a magnetic shield material comprising a magnetic layer containing a magnetic material and an electrically conductive layer containing an electrically conductive material, the electrically conductive layer is designed to have a thickness corresponding to a frequency band of electromagnetic wave to be shielded. More specifically, the thickness of the electrically conductive layer (thickness of the aluminum foil in the drawing) is designed to have a thickness to maximize magnetic field shield effect of the magnetic shield material (thickness of the aluminum foil corresponding to peak value frequency in curve E in the drawing) in a frequency band of electromagnetic wave to be shielded. This makes it possible to obtain good magnetic field shield effect of the magnetic shield material in the frequency band of electromagnetic wave to be shielded.

摘要： A noise current absorber includes a pair of split magnetic bodies formed by equally splitting an annular magnetic body into an open annular shape, and a pair of housing parts capable of housing the split magnetic bodies. The pair of housing parts are coupled, and thus the pair of split magnetic bodies are abutted into an annular shape. The pair of housing parts include a first spring and a pair of second springs. The first spring is disposed in a central region of a bottom surface of the housing part facing the split magnetic body. The pair of second springs are disposed on both sides of the first spring.

摘要： A contact member for which downsizing beyond conventional products is feasible is provided. The contact member includes a base portion, a contact portion, and a spring portion. The spring portion includes a first extension portion, a second extension portion, a third extension portion, and a fourth extension portion. The first extension portion is bent from a rear end of the base portion and extends upward. The second extension portion is bent from an upper end of the first extension portion and extends forward, and its upper surface is made to be a sucked surface that is capable of being attracted to a suction nozzle of an automatic mounting machine. The third extension portion is bent from a front end of the second extension portion and extends forward obliquely downward. The fourth extension portion is bent from a front end of the third extension portion, extends upward obliquely rearward, and is provided with the contact portion on a distal end side in its extension direction.

摘要： A connector fixture includes a fixture body and a positioning member. The fixture body includes a fixing portion, a retaining portion, and a contact portion. When the fixture body is attached to the first connector, the fixing portion determines the relative position between the fixture body and the first connector in a z-axis direction. The contact portion determines the relative position between the fixture body and the first connector in a y-axis direction. The positioning member determines the relative position between the fixture body and the first connector in an x-axis direction. The positioning member is configured to be separable from the fixture body.

摘要： A contact includes a thin plate member having elasticity and conductivity, is disposed between a first member and a second member, and electrically connects the first member and the second member via the thin plate member, and the contact includes a base portion and a movable portion. The base portion has a bonding surface to be bonded to the first member by soldering. The movable portion includes: a contact portion that contacts with the second member; and a connecting portion that connects to the base portion, and is configured to be elastically deformable with respect to the base portion. The connecting portion is gradually separated from the first member. A predetermined range from a connecting position of the connecting portion with the base portion is lower in solder wettability than the bonding surface.
