摘要： PROBLEM TO BE SOLVED: To provide a reactor that does not require any adhesives for assembling a core and has improved assembly properties. SOLUTION: The reactor includes: a pair of coil elements; an annular core 2 including a pair of intermediate cores 2m where each coil element is disposed and a pair of edge cores 2s for connecting edges of both of the intermediate cores; and a bobbin 3 including a cylindrical bobbin 3m for covering an outer periphery of the intermediate cores 2m and a frame-like bobbin 3s abutting on an end face of the coil elements 1. Then, engagement sections (a fitting recess 31 and a fitting projection 32) that fit mutually are provided in the cylindrical bobbin 3m and the frame-like bobbin 3s, respectively. A projecting frame 33 for positioning the edge core 2s is formed in the frame-like bobbin 3s. Further, by fitting the cylindrical bobbin 3m to the frame-like bobbin 3s, a position relationship between the intermediate core 2m and the edge core 2s is held without using any adhesives.

摘要： PROBLEM TO BE SOLVED: To provide a reactor capable of reducing size in a coil axial direction, and to provide a reactor bobbin which is suitable for structuring such a reactor. SOLUTION: A reactor comprises: a coil formed by spirally coiling wire to be wound; a core which is fitted in the coil to be formed in an annular shape; and a frame-shaped bobbin 20F in which the core is fitted and which is brought into contact with both ends of the coil. A contact surface in the frame-shaped bobbin 20F for the coil comprises an inclined surface corresponding to a form of a coil end composed of the wire. With this constitution, the frame-shaped bobbin 20F can be brought into surface contact with the coil end surface. Consequently, no dead space is formed between the contact surface of the frame-shaped bobbin 20F and the coil end surface, and size of the reactor in a coil axial direction can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a reactor core in which the amount of coils to be used can be reduced, a reactor and a manufacturing method of the reactor. SOLUTION: A reactor L comprises a core 1 and a coil C which is disposed in the outer periphery of the core 1 (inner core part 11). The core 1 includes the inner core part 11, an outer core part 12 disposed outside of the coil C, and a pair of connecting core parts 13 connecting both the core parts 11, 12 while covering both terminal portions of the coil C. A closed magnetic circuit passing through the core 1 is formed by exciting the coil C. In the core 1, the core parts 11, 12, 13 are integrated without interposing a gap. The inner core part 11 has a higher saturation magnetic flux density (1.2 times or more) than that of the outer core part 12 and the connecting core part 13. Since the saturation magnetic flux density of the inner core part 11 is higher, even if a cross sectional area of the core part 11 is reduced, a large magnetic flux can be obtained. Furthermore, since the core 1 has a gapless structure, the problem such as noise with the presence of a gap hardly occurs. COPYRIGHT: (C)2013,JPO&INPIT

摘要：【課題】リアクトルの物理量(温度など)を測定するセンサと外部装置とを安定して接続可能なリアクトルを提供する。
【解決手段】リアクトル1Aは、コイル2と、コイル2が配置される磁性コア3と、コイル2と磁性コア3との組合体10を収納するケース4とを具える。ケース4は、底板部と、組合体10の周囲を囲む側壁部41とを具え、側壁部41は絶縁性樹脂により構成されている。側壁部41には、温度センサなどのリアクトル1Aの物理量を測定するセンサに配線71を介して連結されたコネクタ部72を掛止するコネクタ掛止部44が側壁部41の構成樹脂により一体に成形されている。コネクタ掛止部44にコネクタ部72を掛止して固定することで、コネクタ部72がケース4に安定して保持され、リアクトル1Aは、コネクタ部72と外部装置のコネクタ部との接続を安定して行える。
