As a plug with a built-in noise filter element, for example, Utility Application No. 62177788 (November 1988)
(filed on the 20th). This is a noise filter in which a chiyoke coil, in which a pair of windings are wound around a magnetic annular core, is connected between the plug terminal and the cord. A winding consisting of a pair of insulated wires is wound on the insulating cover. This insertion plug includes a protrusion that is inserted into a hole in a chiyoke coil, a noise filter element holding part that has a plurality of peripheral walls covering the outer periphery of the protrusion, and a connection part that accommodates the connection part between the cord-side lead end of the noise filter element and the cord conductor. It is composed of an integral fixing member consisting of a accommodating part and an insulating base that fixes the rear part of the plug terminal while giving a predetermined spacing dimension to the plug terminal. The hole of the chiyoke coil is inserted through the protruding body of the noise filter element holding part, the chiyoke coil is held while being protected by a plurality of surrounding walls, and the winding end of the chiyoke coil is connected to the connection terminal fixed to the cord connection part accommodating part. The wire is connected to the cord conductor by the wire, and the other winding end is connected to the plug terminal. Thereafter, the plug body is integrally molded from the rear end of the plug terminal to the end of the cord by injection molding.

上する等の多くの利点を有している。 This plug has a protruding body of an insulating base inserted and fitted into the hole of the chiyoke coil, and the outer periphery of the chiyoke coil is covered with a plurality of peripheral walls, which eliminates the movement of the chiyoke coil due to the molding pressure that occurs when the plug body is integrally molded. This prevents the exposed coil from being exposed on the surface of the plug body, prevents disconnections and short circuits at the connection portion of the windings, and improves quality. In addition, when holding the chiyoke coil in the plug body, it is only necessary to insert and fit the chiyoke coil into the protrusion of the noise filter element holding part by holding the hole in the chiyoke coil, which is a simple operation and improves productivity. It has many advantages.
しかし、提案中の差込みプラグによると、以下

および部品数が多く、差込みプラグのコストが
低減できず、かつ、生産性の向上に限界があ
る。(1) Cover the annular core with a pre-formed insulating cover, wind the winding wire on top of it to form a chiyoke coil, and then fit the chiyoke coil into the noise filter element holding part of the insulating base that has been molded in advance. In order to insert the plug, the number of processes and parts is large, such as molding the insulating cover, fitting and molding the insulating base, and fitting and inserting the chiyoke coil into the noise filter element holding part, making it impossible to reduce the cost of the plug and production. There are limits to sexual improvement.
(2) 環状コアーには絶縁カバーの嵌合、巻線の巻

持部がチヨークコイルを覆うため、プラグ本体
を小型化することが難しい。(2) Since the annular core is fitted with an insulating cover and the winding wire is wound, and the noise filter element holding portion covers the choke coil, it is difficult to downsize the plug body.
(3) 環状コアーに絶縁カバーを被覆し、更に巻線

に支障をきたす。(3) Since the annular core is covered with an insulating cover and the winding wire is further wound around the annular core, it is not possible to check whether the annular core is damaged or not. Since the annular core is made of sintered magnetic material such as ferrite, it is susceptible to impact and easily breaks. Therefore, it is necessary to check the characteristics of the noise filter element to identify the presence or absence of damage, which hinders cost reduction and productivity improvement.

The outer circumferential wall 221 of the annular lid body 220 is fitted into the ring 6 . Due to this fitting, the annular ferrite core 36 is covered by the annular container 210 and the annular lid 220, and the annular ferrite core 36 is
are arranged so that they are close together. Then, a pair of winding wires (0.75φ copper wire insulated with polyurethane) 32, 3 are passed through the hole 223 of this covering.
Wind 3. The winding is performed by hand or by an automatic winding machine, and the number of windings is about 10 to 15 turns with the insertion groove 226 of the winding division plate 224 as described later as a boundary. At this time, the winding wire needs to be wound with a tension that does not change the wound shape due to the molding pressure during molding of the plug body, and the tension is preferably about 3.0 kg or more. When the windings 32 and 33 have been wound a predetermined number of turns, the winding division plate 224 is inserted into the insertion groove 226 of the annular lid body 220 and the insertion groove 218 of the inner cylinder peripheral wall 215 to separate the pair of windings 32 and 33. Separate and insulate.

As explained above, according to the plug manufactured according to the present invention, the annular core of the noise filter element is accommodated on one side of the insulating cover that fixes the rear part of the plug terminal with a predetermined interval between the plug terminals. Since the annular core accommodating portion is provided and the pair of windings are wound around the annular core accommodating portion, the number of parts can be reduced and the plug can be made smaller. Therefore, cost reduction can be achieved. Further, according to the method of manufacturing an insertion plug of the present invention, in addition to reducing the number of parts, the number of steps can be reduced, and productivity can be improved. Furthermore, since the annular core can be stored in the annular core accommodating portion while checking for damage, quality can be improved.
