Abstract: One end of a bus bar for leading an output voltage output from a switching power supply to the outside is a connection terminal connected to an output end associated with the switching power supply, while the other end is an output terminal VO. A ferrite core has a through-hole through which the bus bar is disposed. Electromagnetic coupling from the switching power supply is suppressed between the output terminal VO of the bus bar and at least a part of the ferrite core on the output terminal VO side along the bus bar. In this way, electromagnetic coupling of a part of a choke coil including the ferrite core with the bus bar penetrating therethrough on the output terminal VO side and the switching power supply is suppressed, whereby propagation of noise to the output terminal VO is suppressed.
Abstract translation: 用于将从开关电源输出的输出电压引导到外部的母线的一端是连接到与开关电源相关联的输出端的连接端子，而另一端是输出端子VO。 铁氧体磁芯具有通孔，母线通过该通孔设置。 汇流条的输出端子VO与汇流条的输出端子VO侧的铁氧体磁心的至少一部分之间抑制来自开关电源的电磁耦合。 以这种方式，抑制了包括铁氧体磁芯的扼流线圈的一部分与在输出端子VO侧穿过的母线的电磁耦合和开关电源，由此抑制了对输出端子VO的噪声传播。

Abstract: A securing mechanism comprises a supporting column, an elastic piece, and a plurality of locking pieces. When the supporting column is inserted into a hole, at least one of the plurality of locking pieces is caught by or brought into pressure-contact with an outlet-side peripheral portion of the hole or an inner circumferential portion of the hole. The plurality of locking pieces form a plurality of arrays extending in a projection direction of the supporting column. The locking pieces included in each array of the plurality of arrays are aligned spaced apart from one another in the projection direction of the supporting column. The plurality of arrays comprise a first array and a second array; positions of the locking pieces in the first array are displaced from positions of the corresponding locking pieces in the second array in the projection direction of the supporting column.

Abstract: A fixture includes two mounted portions and an interposing portion. At least the one mounted portion includes a strut portion, a check portion, and an abutment portion. The strut portion is insertable into a mounting hole provided in a mounting target. The check portion is caught on the mounting target on an outlet side of the mounting hole. The abutment portion abuts on the mounting target on an inlet side of the mounting hole. When any one of the mounting target or the fixture vibrates, the check portion and the abutment portion deform to suppress a vibration in a direction parallel to an insertion direction. When any one of the mounting target or the fixture vibrates, the interposing portion deforms to suppress a vibration in a direction parallel to a plane orthogonal to the insertion direction.
