Reactor, reactor manufacturing method, and reactor component

摘要

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.

主权项

1. A reactor, comprising:
a combined product and a case storing the combined product, the combined product including a coil made of a wound wire and a magnetic core where the coil is disposed, wherein the case includes
a bottom plate portion being brought into contact with a fixation target when the reactor is installed in the fixation target,a side wall portion that is independent of the bottom plate portion, that is integrated with the bottom plate portion by a fixation member, and that surrounds a periphery of the combined product,a joining layer that is formed at one face of the bottom plate portion to fix the coil to the bottom plate portion, anda terminal fitting that is fixed to the side wall portion, an end portion of the wire structuring the coil being electrically connected to the terminal fitting, wherein the terminal fitting has, on its one end side, a plurality of joining pieces that are disposed at positions opposing to the end portion of the wire, the end portion of the wire being interposed in a space formed by the joining pieces.
