た塗料も同様に流動化し鍔部外端面に流出する。(Problem to be solved by the invention) In the inductance element described in the above-mentioned Japanese Patent Publication No. 57-19563, the outer end surface of the flange including the connecting part between the lead wire and the lead wire is coated in a raised approximately hemispherical shape. In this case, during the process of heating and curing the paint, the heated paint becomes fluidized and cannot maintain its substantially hemispherical shape, and after flowing in the axial direction of the lead wire, the paint hardens. Similarly, the paint applied to the windings of the core body becomes fluidized and flows out to the outer end surface of the flange.

易いという問題がある。 Due to the above phenomenon, each end face of the inductance element becomes conical, and the coating film on the outer edge of the magnetic core flange becomes thinner. Therefore, the length of the inductance element in the axial direction becomes large, and the coating film on the edge portion becomes thin. Furthermore, since each end face of the element is conical, the centering accuracy of the taping supplied to the automatic insertion machine is also poor. Therefore, there is a problem that there is less margin for the pitch of the automatic insertion machine, and the connection part is likely to be disconnected.

塗布量が多くなるという問題がある。 Furthermore, in the case of the structure described in Utility Model Publication No. 56-519292, the outer end surface including the connecting portion from the peripheral surface of the magnetic core around which the winding is wound is integrally coated with an elastic synthetic resin layer, so that the lead wire The connection between the lead wire and the lead wire is held by a synthetic resin layer that has elasticity. Because it is a thin layer that is approximately the same as the outer diameter of the wire, when the lead wire is bent near the leader wire connection part, the leader wire is likely to be pulled due to deformation of the elastic synthetic resin layer and breakage may occur. There is a problem. In addition, since the paint is applied from the circumferential side to the end face of the magnetic core, the coating film tends to be thinner at the edges, which are susceptible to external forces from the winding lead wires, so if the edge parts are thickened, the overall coating film must be thickened. ,
There is a problem that the amount of coating increases.

To provide an inductance element which has a small length in the axial direction of the element, has enough room for an automatic insertion machine, and is free from disconnection at the connecting part between a lead wire and a lead wire.

る。(Structure of the Invention) (Means for Solving the Problems) The inductance element of the present invention includes a magnetic core having an approximately H-shaped cross section, which has flanges at both ends of the body, and one end of which is fixed to a concave portion on the outer end surface of both flanges. A lead wire extending in the axial direction and a winding wound around the body of the magnetic core are provided, and both ends of the lead wire drawn out across the flange of the winding are attached to the base of the lead wire. In the inductance element connected by winding, an annular inelastic synthetic resin layer made of an inelastic synthetic resin is formed around both flanges of the magnetic core, an elastic synthetic resin layer is formed around the outer periphery of the winding, and the The outer end surface of the flange including the connection portion between the lead wire and the outgoing wire, the annular non-elastic synthetic resin layer and the elasticity-retaining synthetic resin layer are coated with an outer coating layer made of non-elastic synthetic resin.

が引張られて断線することがない。(Function) In the inductance element of the present invention, when the elastic synthetic resin layer on the outer periphery of the winding is fluidized by heating during drying due to the annular inelastic synthetic resin layer on the circumferential surface of the flange of the magnetic core, Since the flow is prevented from flowing into the outer end surface of the flange, the elastic synthetic resin layer does not intervene in the connection between the winding lead wire and the lead wire located on the end surface of the flange, and the connection portion is made of inelastic material. Covered only with a resin layer, the connecting portion of the lead wire will not be pulled and disconnected due to bending of the lead wire or the like.

の引出線の損傷を防止することができる。 In addition, the inelastic annular synthetic resin layer covers the lead wire drawn out from the winding of the magnetic core to the flange, and the outer coating layer that covers the outside becomes thinner at the edge of the flange. Since there are no edges, damage to the leader line at the edge can be prevented.

One end of the lead wires 4, 4 is attached to the flange 3 at the center of the outer end surface of the
It is inserted into the recess 11 of the magnetic core, fixed with adhesive 12, and extends in the axial direction of the magnetic core.

成される外被塗料層１０が熱膨脹によつて発生す
る気泡によつて針状の孔が生ずることがない。 The elastic synthetic resin layer 8 formed on the outer periphery of the winding 5 becomes fluid when heated during drying and permeates into the gaps between the windings 5 wound around the body 2, thereby eliminating air present in the gaps. Therefore, the outer coating layer 10 formed on the outer periphery will not have needle-shaped holes due to air bubbles generated by thermal expansion.
また流動化した弾性合成樹脂層８は鍔部３の環
状合成樹脂層７によつて端面側に流入するのを阻

According to the present invention, the inelastic annular synthetic resin layer formed on the outer periphery of the flange prevents the elastic synthetic resin layer formed on the winding from flowing out to the outer end surface of the flange due to flow during heating. Therefore, the connection part between the lead wire and the outgoing wire located on the outer end surface of the flange part is not covered with the flowing elastic synthetic resin, and the connection part is fixed and held by the inelastic outer coating layer. There is no risk of winding wire breakage, etc.
また鍔部を跨いで引出された巻線の引出線は外

されているから移動することがなく、鍔部のエツ
ジとの擦れにより断線するようなこともない。 In addition, the outer surface of the winding wire pulled out across the flange is fixed to the outer surface of the flange with an inelastic annular synthetic resin layer, so it does not move and breaks due to rubbing against the edge of the flange. There's nothing to do.

出線部の保護効果を向上させることができる。 Furthermore, because the annular synthetic resin layer formed on the flange makes the edges of the flange obtuse, the thickness of the outer coating layer applied to the outer surface becomes especially thinner at the edges of the flange. Therefore, the protection effect of the leader line portion related to the edge can be improved.
