摘要:
The present invention is directed to a reactor 1 including a combined product 10 made up of a coil member 2 and a magnetic core 3, and a case 4 storing the combined product 10. The case 4 is formed by a combination of a side wall portion 41 surrounding the combined product 10 and a bottom plate portion 40 being a member separate from the side wall portion 41. Between the bottom plate portion 40 of the case 4 and the coil member 2 (coils 2a and 2b), an insulating sheet 42 is interposed. In order to fabricate the reactor 1, the insulating sheet 42 is disposed on the bottom plate portion 40, and the combined product 10 is disposed on the insulating sheet 42. Then, the side wall portion 41 is disposed from above the combined product 10, and the side wall portion 41 and the bottom plate portion 40 are engaged with each other.

An annular core (14) of a reactor (10) has two core mold members (24a, 24b) integrated by bonding core segments (32) and gap plates (34) with a cyanoacrylate-based adhesive agent (36) to each other and insert-molding the bonded core segments (32) and gap plates (34) with a thermoplastic resin (38).

A reactor including an assembly of a coil, a magnetic core on which the coil is disposed, and a case that houses the assembly. The case includes an installation face, a side wall that is removably attached to the installation face and surrounds the periphery of the assembly, and a heat dissipation layer formed on the inner face of the installation face and interposed between the installation face and the installation-side face of the coil. The installation face consists of aluminum, the side wall consists of an insulating resin, and the heat dissipation layer consists of an adhesive with high thermal conductivity and excellent insulation. The installation face is separate from the side wall, making it easy to form the heat dissipation layer, and having excellent heat dissipation. The side wall consists of an insulating resin, thus reducing the gap between it and the coil.

A reactor 1 of the present invention includes: a combined product 10 provided with a coil 2 and a magnetic core 3 where the coil 2 is disposed; and a case 4 storing the combined product 10. The case 4 includes: a bottom plate portion 40 fixed to a fixation target when the reactor 1 is installed in the fixation target; a side wall portion 41 attached to the bottom plate portion 40 to surround the combined product 10; and a heat dissipation layer 42 formed on the inner face of the bottom plate portion 40 to be interposed between the bottom plate portion 40 and the coil 2. The bottom plate portion 40 is made of aluminum, and the side wall portion 41 is made of an insulating resin. The heat dissipation layer 42 is made of an adhesive agent whose thermal conductivity is high and which exhibits an excellent insulating characteristic. Since the bottom plate portion 40 is structured as a separate member from the side wall portion 41, the heat dissipation layer 42 can easily be formed and, moreover, the heat dissipation layer 42 can be made of a material possessing an excellent heat dissipating characteristic. Since the insulator 5 evenly presses the coil 2 against the heat dissipation layer 42, an even more excellent heat dissipating characteristic is achieved.

A reactor being small in size and exhibiting excellent productivity, a method for manufacturing the same, and a reactor component suitable as the constituent component of the reactor are provided. The reactor includes a combined product including a coil and a magnetic core, and a case storing the combined product. The case includes a bottom plate portion made of aluminum, a side wall portion made of an insulating resin, and a joining layer formed on the inner face of the bottom plate portion for fixing the coil. The bottom plate portion and the side wall portion are independent separate members, which are integrated with each other by bolts and the like. Terminal fittings having a pair of joining pieces, which are disposed at the positions opposing to the end portions of the wire structuring the coil, are fixed to the side wall portion. Since each end portion of the wire is interposed in the space formed by the joining pieces, the wire and the terminal fittings can be electrically connected to each other without the necessity of using a separate jig. Since the joining layer is made of an adhesive agent exhibiting excellent thermal conductivity and insulation, the reactor possesses an excellent heat dissipating characteristic.

An electric power distribution unit is formed independently of a bus bar board by integrating a plurality of switching devices. The electric power distribution unit includes a heat radiation plate and a plurality of unit-forming bus bars. The switching devices are mounted on the bus bars. Input and output terminals are formed by bending appropriate unit-forming bus bars toward the heat radiation plate, and are connected to connection terminals of the bus bar board. A circuit is formed in which electric power inputted to the input terminal is supplied through the switching devices to the output terminals.
