【従来の技術】[Prior art]

従来この種の変成器は、図4及至図6に示すようにホルダー9が下つぼみの形 状になっており、EE型磁芯8に挿入係止された時、EE型磁芯8の圧接方向へ の加圧力を確保する為、EE型磁芯の外形寸法に対し、ホルダーのEE型磁芯へ の挿入口が小さくなっており、ホルダーのEE型磁芯への挿入作業が困難であり 、且つ挿入係止後には、ホルダーの抜け防止の為、EE型磁芯との接着固定が必 要であった。 In the conventional transformer of this type, as shown in FIGS. 4 to 6, the holder 9 has a shape of a lower bud, and when the holder 9 is inserted and locked in the EE type magnetic core 8, the pressure contact of the EE type magnetic core 8 is performed. In order to secure the pressing force in the direction, the insertion opening of the holder into the EE type magnetic core is smaller than the external dimensions of the EE type magnetic core, making it difficult to insert the holder into the EE type magnetic core. In addition, after insertion and locking, it was necessary to adhere and fix the EE type magnetic core to prevent the holder from coming off.

【考案が解決しようとする課題】[Problems to be solved by the device]

図4、図5、図6に示す従来の変成器にあっては、ホルダー9が下つぼみの形 状、すなわちホルダーの開口部2がEE型磁芯8の外形寸法よりも狭くなってい る。そのため変成器を組み立てる際にホルダー9の開口部2を、指及び治具を使 用し拡げてEE型磁芯8に挿入係止する必要があり、変成器組み立て作業に多大 の時間を要していた。更にEE型磁芯8とホルダー9は何ら係止する部分が無い ためズレ動く場合があり、ホルダー9の端部とEE型磁芯8を接着する必要があ った。 本考案は上記課題を解決するため、EE型磁芯の外足側面に、図2に示す背面 方向両側端部に切り込み状の凹凸部を形成し、ホルダーはコの字の両先端の側面 にツメ状部を設けたものである。本手段によりEE型磁芯の固定が容易になり、 また、接着工程が除去される変成器を提供することを目的とする。 In the conventional transformers shown in FIGS. 4, 5 and 6, the holder 9 is in the shape of a lower bud, that is, the opening 2 of the holder is narrower than the outer dimensions of the EE type magnetic core 8. Therefore, when assembling the transformer, it is necessary to expand the opening 2 of the holder 9 with fingers and a jig and insert and lock it in the EE type magnetic core 8, which requires a lot of time for the transformer assembling work. Was there. Further, since the EE type magnetic core 8 and the holder 9 do not have any engaging portion, there is a case where they are displaced, and it is necessary to bond the end portion of the holder 9 and the EE type magnetic core 8. In order to solve the above problems, the present invention forms notch-shaped concave and convex portions at both end portions in the rear direction shown in FIG. 2 on the side surface of the outer foot of the EE type magnetic core, and the holder is formed on the side surfaces at both ends of the U-shape. A claw-shaped portion is provided. It is an object of the present invention to provide a transformer in which the EE type magnetic core can be easily fixed by this means and the bonding step can be eliminated.

本考案は、端子付ボビンにEE型磁芯が横方向より対称に組まれ、その上部よ りコイル全体を覆うようにコの字形のホルダーが組み込まれてなる変成器におい て、EE型磁芯は外足側面でEE型磁芯の背面方向両側端部に切り込み状の凹凸 部を形成し、該凹凸部の凸部は上側辺がテーパー部を形成し、凹部はホルダーの ツメ状部と係止が可能となるようツメ状部と相似形を形成している。更にEE型 磁芯を保持するホルダーはコの字形を形成し、該ホルダーの両先端の側面にツメ 状部を形成し、該ツメ状部が該EE型磁芯の切り込み状の凹凸部の凸部でホルダ ーの開口部が拡げられ、凹部に係止するように構成したことを特徴とする変成器 である。 The present invention is a transformer in which an EE-type magnetic core is assembled symmetrically from the lateral direction on a bobbin with terminals, and a U-shaped holder is incorporated so as to cover the entire coil from the upper part thereof. Is a notch-shaped uneven portion formed on both sides of the outer foot side in the back direction of the EE-type magnetic core. The convex portion of the uneven portion has a taper portion on the upper side, and the concave portion is engaged with the tab portion of the holder. It has a similar shape to the claw-shaped part so that it can be stopped. Further, the holder for holding the EE-type magnetic core has a U-shape, and the claw-shaped portions are formed on the side surfaces of the both ends of the holder, and the claw-shaped portions are the projections of the notched concave and convex portions of the EE-type magnetic core. The transformer is characterized in that the opening of the holder is widened by the part and is locked in the recess.

【作用】[Action]

本考案は、ホルダーのコの字の両先端の側面にツメ状部を設け、EE型磁芯に は外足側面で背面方向両側端部に切り込み状の凹凸部を構成したものである。ホ ルダーのEE型磁芯への挿入時、EE型磁芯の外足側面で背面方向に形成された 切り込み状の凹凸部の凸部のテーパー部によりホルダーの開口部先端が挿入しや すくなり、挿入後は切り込み状の凹凸部の凹部により、ホルダー先端のツメ状部 が係止する為に確実に係止する。又、挿入後の接着工程を除去することができる 。 According to the present invention, claw-shaped portions are provided on both side surfaces of the U-shaped tip of the holder, and the EE type magnetic core is provided with cut-out concave and convex portions at both lateral end portions on the outer foot side surface. When inserting the holder into the EE-type magnetic core, the tip of the opening of the holder can be easily inserted due to the taper of the convex part of the notch-shaped uneven part formed on the outer side surface of the EE-type magnetic core in the rear direction. After the insertion, the recesses of the notch-shaped uneven parts ensure that the tabs at the tip of the holder are locked. Also, the bonding step after insertion can be eliminated.
