  • Patent number: 9828151
    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.

  • Patent number: 9704638
    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.

  • Publication number: 20170194090
    Abstract: An object is to provide an output-noise reduction device that can achieve more effective fixing of an output terminal. A conducting bar in a noise filter module has a front end portion provided with a bent portion bent upward to be orthogonal with the front and rear direction. This bent portion serves as the resistance against the secondary molded member with respect to movement of the conducting bar in the front and rear direction. Thus, when the force in the detaching direction (the front and rear direction) is applied in a state where the bolt is fixed to the connection terminal of the supplying device, movement of the conducting bar in the front and rear direction with respect to the frame molded member can be prevented, with the bent portion serving as the resistance against the frame molded member.
