Claims (7)

A reactor in which a coil is wound around the core;
A terminal block in which the coil of the reactor is connected to one end of a terminal plate held by an insulating base and an external device is connected to the other end;
An external structure to which the reactor and the terminal block are fixed by fastening;
In electrical equipment with
An electric device characterized in that the terminal block and the reactor are positioned by concave-convex fitting.   The reactor includes a fixing plate having a fastening through-hole, and the terminal block and the reactor are positioned by concave-convex fitting in a part of resin for molding the fixing plate. The electrical apparatus according to 1.   The reactor includes a fixing plate having a fastening through hole, the positioning plate has a positioning through hole, and the positioning rod is fitted and positioned in the positioning through hole. The electric device according to claim 1, wherein   The positioning bar extends from the terminal block, passes through the positioning through-hole of the fixing plate member, and is fitted into the concave portion of the external structure so that the terminal block, the reactor, and the external structure are uneven. The electrical device according to claim 3, wherein the electrical device is positioned by fitting.   The positioning bar extends from the external structure, passes through the positioning through hole of the fixing plate, and is fitted into the recess of the terminal block, thereby unevenly forming the terminal block, the reactor, and the external structure. The electrical device according to claim 3, wherein the electrical device is positioned by fitting.   The reactor includes a fixing plate having a fastening through-hole, the fixing plate has a protrusion, and the protrusion is positioned by fitting into a recess of the terminal block. The electrical apparatus according to 1.   The electric device according to claim 6, further comprising a protrusion for an external structure in the fixing plate member, wherein the protrusion for the external structure is fitted and positioned in a recess of the external structure.
