Patent number: 11942261Abstract: A common-mode choke coil includes a core having a winding core portion, a first winding and a second winding. A winding start side region ranges from one end portion to a position where a first winding is brought into contact with the winding core portion, and a winding finish side region ranges from the other end portion to a position where a second winding is brought into contact with the winding core portion. The first winding is wound on the winding core portion such that the first winding is positioned on a negative direction side in an x axis direction with respect to the second winding at the same turn in the winding start side region and the second winding is interposed between the first winding and the winding core portion in the winding finish side region.Type: GrantFiled: June 4, 2021Date of Patent: March 26, 2024Assignee: Murata Manufacturing Co., Ltd.Inventor: Takayuki Yamakita

Patent number: 10361028Abstract: A method for manufacturing a wound coil which has a stable appearance configuration with improved shape accuracy of a coating resin formed on the wound coil. A wound coil element is pressed into a holding jig including an elastic holding hole, and held therein such that an upper end of a coil is level with or lower than an upper end of the holding hole, and a gap G is present between an inner surface of the holding hole and the coil. Next, a flowable coating resin is supplied into the holding hole holding the wound coil element such that the coating resin is held without flowing away downwardly from the gap G, and the upper end 16a of the coil is buried in the coating resin. Next, the supplied coating resin is subjected to curing, thereby forming a wound coil.Type: GrantFiled: May 26, 2016Date of Patent: July 23, 2019Assignee: Murata Manufacturing Co., Ltd.Inventor: Takayuki Yamakita

Patent number: 9842691Abstract: A wire winding method which can prevent twisting tendency of a wire and the occurrence of damage on the wire. The wire winding method includes: a first step of making a plurality of wires pass through a tensioner and a nozzle sequentially and fixing distal ends of the plurality of wires to a core side; and a second step of winding the plurality of wires on the core while twisting the plurality of wires by making the nozzle revolve around the core such that a mutual positional relationship between a plurality of wire insertion holes formed in the nozzle through which the plurality of wires are made to pass respectively with respect to the tensioner is set to a fixed value.Type: GrantFiled: June 16, 2016Date of Patent: December 12, 2017Assignee: Murata Manufacturing Co., Ltd.Inventor: Takayuki Yamakita
