[Technical field to which the device belongs]

 The present invention relates to a reactor device.

[0002]

[Prior art]

 Reactor equipment is used to absorb reactive power due to large inductive reactance in an AC circuit, or to give reactance only to AC in a circuit where AC and DC overlap. As a configuration of such a reactor device, there is one as shown in FIG. The reactor device 61 includes an air gap core reactor 2, a support substrate 63 that supports the reactor 2, and insulating type connection terminal portions 65 attached to both ends of the winding 4 of the reactor 2. As shown in the schematic vertical sectional view of FIG. 4B, the insulated connection terminal portion 65 is obtained by soldering the lead wire 66 to the end portion of the winding 4 of the reactor 2 and connecting the connection terminal 67 to the end portion of the lead wire 66. After being fixed by soldering, the insulating silicon tube 68 is covered from the lead wire 66 to the base of the winding 4.

First, in the reactor device 61 in which a large current flows, the amount of heat generated from the winding 4 is large, and the insulated connection terminal portion 65 has the complicated structure as described above. It is necessary to insulate the wire 66, and secondly, because the connection terminal 67 is configured to move freely, the conductor part composed of the winding 4 and the lead wire 66 intersects or short-circuits due to contact with an external one. This is to prevent this.

[0004]

[Problems to be solved by the device]

 However, the conventional reactor device 61 has the following problems. (1) With the configuration of the insulating type connection terminal portion 65, the caulking work and the soldering work of the winding wire 4 and the lead wire 66, and the caulking work and the soldering work of the connection terminal 67 and the lead wire 66 are performed. In addition, it is necessary to cover the silicon tube 68, which complicates the manufacturing and assembling work and increases the number of parts.

(2) In the work of assembling the reactor device 61 to a predetermined product, each of the insulating type connecting terminal portions 65 can freely move by itself, so that the insulating type connecting terminal portion 65 at the time of assembling is installed. Is different in each reactor device 61. Therefore, when the insulated connection terminal portion 65 is connected to the connected terminal (not shown) in a state close to the reactor 2, a part of the silicon tube 68 of the insulated connection terminal portion 65 is generated by the heat generated from the reactor 2. May be impaired, and the insulation may deteriorate. In addition, there is a problem that the work of assembling the reactor device 61 varies from person to person, and it is difficult to standardize the work of assembling. An object of the present invention is to provide a reactor device that solves the above problems (1) and (2).
