Description

コネクタconnector
　本発明は、各種電子機器或いは回路基板間をつなぐコネクタに関し、特に、各種電子機器から発生する不用な電磁波を低減することができるコネクタに関する。 The present invention relates to a connector for connecting various electronic devices or circuit boards, and more particularly to a connector capable of reducing unnecessary electromagnetic waves generated from various electronic devices.
　通信機器や各種電子機器からの電磁波が、外部に放射されたり伝送されたりすることで、外部及び内部干渉による機器自体の誤動作などの問題が大きくなってきている。特に、最近の通信技術、デジタル技術の進歩及び信号の高速化に伴い、高周波側の不要な電磁波（ノイズ）が問題となってきている。このような不要電磁波の発生、漏洩、相互干渉による誤動作への対策として、ノイズ発生源にシールドを施す方法やノイズ伝送線路にノイズフィルタ等を挿入する方法がとられている。最近では、コネクタから出る或いはコネクタに入る電磁波によるＥＭＩ（Electro　Magnetic　Interference）が問題となってきており、コネクタに対してＥＭＣ(Electro　Magnetic　Compatibility)性能が求められてきている。 As electromagnetic waves from communication devices and various electronic devices are radiated or transmitted to the outside, problems such as malfunctions of the devices themselves due to external and internal interference are increasing. In particular, unnecessary electromagnetic waves (noise) on the high frequency side have become a problem with recent advancements in communication technology and digital technology and higher signal speeds. As countermeasures against such malfunction due to the generation, leakage, and mutual interference of unnecessary electromagnetic waves, a method of shielding a noise generation source or a method of inserting a noise filter or the like in a noise transmission line is taken. Recently, EMI (Electro Magnetic Interference) due to electromagnetic waves coming out of or entering a connector has become a problem, and EMC (Electro Magnetic Compatibility) performance has been demanded for the connector.
　コネクタに対するＥＭＩ対策の従来技術として、特許文献１では、図１５に示すように、信号伝送や通信時等に発生する不要な電磁波の漏洩を吸収し得る電子機器間のコネクタ９００が提案されている。図１５に示すコネクタ９００は、接続ケーブル９１１の先端に設けられたコネクタハウジング９０２と、接続ケーブル９１１内の複数本の伝送線（図示せず）と配線接続されているコネクタピン９０３とから構成されている。そして、コネクタハウジング９０２の外側に電磁波吸収材９０５を塗布し固化させるか（図１５に示した従来例）、コネクタハウジング９０２内に電磁波吸収材９０５を充填させるか、電磁波吸収材９０５を含有した合成樹脂材を成形加工してコネクタハウジング９０２とするかの手段を用いて、安価にして不要な電磁波を効率よく吸収できるコネクタが得られるとしている。特に、電磁界エネルギーの熱変換、或いは反射させる等の特性を利用して吸収する電磁波吸収特性を有する電磁波吸収材９０５として、扁平状に加工された軟磁性体の磁性粉末を用いており、例えば、三菱マテリアル株式会社製の不繊布型電波吸収材“エミクロス”（商品名）が好適であるとしている。 As a conventional technique for EMI countermeasures for a connector, Patent Document 1 proposes a connector 900 between electronic devices that can absorb leakage of unnecessary electromagnetic waves generated during signal transmission or communication, as shown in FIG. . A connector 900 shown in FIG. 15 includes a connector housing 902 provided at the distal end of the connection cable 911 and connector pins 903 that are connected to a plurality of transmission lines (not shown) in the connection cable 911. ing. Then, the electromagnetic wave absorbing material 905 is applied to the outside of the connector housing 902 and solidified (conventional example shown in FIG. 15), the electromagnetic wave absorbing material 905 is filled in the connector housing 902, or the synthetic containing the electromagnetic wave absorbing material 905 is contained. It is said that a connector that can absorb unnecessary electromagnetic waves efficiently can be obtained by using a means of molding a resin material into the connector housing 902. In particular, as an electromagnetic wave absorber 905 having an electromagnetic wave absorption characteristic that absorbs by utilizing characteristics such as heat conversion of electromagnetic field energy or reflection, a soft magnetic material powder processed into a flat shape is used, for example, In addition, it is said that a non-woven cloth type electromagnetic wave absorber “Emicloth” (trade name) manufactured by Mitsubishi Materials Corporation is suitable.

And is formed integrally with the holding portion 12. Since the case 11 and the holding part 12 are formed using a synthetic resin material, they can be easily manufactured by injection molding or the like.
　ケース１１と一体で形成された保持部１２は、３本の端子１３が貫通されており、３本の端子１３の延出方向が、ケース１１の上面１１ｔ、底面１１ｂ及び側面１１ｓに対して、略平行になるように、３本の端子１３を保持して形成されている。また、保持部１２の背面側（図１に示すＹ１側）には、３本の伝送線１９ｃを保護するための保護カバー１８がスナップ係合されている（詳細の構造は図示していない）。 The holding portion 12 formed integrally with the case 11 has three terminals 13 extending therethrough, and the extending direction of the three terminals 13 is relative to the upper surface 11t, the bottom surface 11b, and the side surface 11s of the case 11.

Further, a protective cover 18 for protecting the three transmission lines 19c is snap-engaged on the back side (Y1 side shown in FIG. 1) of the holding portion 12 (detailed structure is not shown). .
　また、ケース１１には、図２ないし図４に示すように、フィルム状の磁性体シート１５がケース１１の上面１１ｔ及び底面１１ｂに埋め込まれており、磁性体シート１５は、３本の端子１３を囲うように上下で挟み込む位置に配置されるとともに、３本の端子１３の延出方向に対して、略平行になるように配置されている。なお、ケース１１には、図示していないが、相手方コネクタがコネクタ１０１に挿入された際に、相手方コネクタと係合させるための係止構造が設けられていることは言うまでもない。 2 to 4, a film-like magnetic sheet 15 is embedded in the upper surface 11t and the bottom surface 11b of the case 11, and the magnetic sheet 15 includes three terminals 13 as shown in FIGS. And is arranged so as to be substantially parallel to the extending direction of the three terminals 13. Although not shown, the case 11 is provided with a locking structure for engaging with the mating connector when the mating connector is inserted into the connector 101.
　ケース１１に埋め込まれた磁性体シート１５は、図５に示すように、ＡＢＳ（アクリロニトリルブタジエンスチレン）、ＰＰ（ポリプロピレン）等の合成樹脂Ｐ５と、扁平状磁性粉末Ｍ５とから構成される。また、磁性体シート１５は、合成樹脂Ｐ５のマトリックスに、扁平状磁性粉末Ｍ５の長手方向が磁性体シート１５の面内方向ＰＤの所望の方向に揃えた形で、複数の扁平状磁性粉末Ｍ５を並べるように配向ＨＤさせている。ここで言う配向ＨＤとは、複数の扁平状磁性粉末Ｍ５の平均傾き角度が磁性体シート１５の面内方向ＰＤに対して、４５°以下の状態を指し、好ましくは１０°以下の状態を指している。図６に示す複数の扁平状磁性粉末Ｍ５の傾き角度が４５°以上の角度の方向ＮＤの場合、扁平状磁性粉末Ｍ５の長手方向が磁性体シート１５の面内方向ＰＤに対して、複数の扁平状磁性粉末Ｍ５を並べるように配向ＨＤさせているとは言えない。 As shown in FIG. 5, the magnetic sheet 15 embedded in the case 11 is composed of a synthetic resin P5 such as ABS (acrylonitrile butadiene styrene) or PP (polypropylene), and a flat magnetic powder M5. Further, the magnetic sheet 15 has a plurality of flat magnetic powders M5 in a matrix of the synthetic resin P5 such that the longitudinal direction of the flat magnetic powder M5 is aligned with a desired direction in the in-plane direction PD of the magnetic sheet 15. Are aligned so as to be aligned. The orientation HD as used herein refers to a state in which the average inclination angle of the plurality of flat magnetic powders M5 is 45 ° or less, preferably 10 ° or less with respect to the in-plane direction PD of the magnetic sheet 15. ing. When the inclination angle of the plurality of flat magnetic powders M5 shown in FIG. 6 is the direction ND having an angle of 45 ° or more, the longitudinal direction of the flat magnetic powder M5 is a plurality of in-plane directions PD of the magnetic sheet 15. It cannot be said that the flat magnetic powder M5 is oriented HD so as to be arranged.
　このようにして、複数の扁平状磁性粉末Ｍ５の磁化が磁性体シート１５の面内方向ＰＤの所望の方向に配向するようになり、磁性体シート１５の磁界の向きが、所望の方向に揃うようになる。このことにより、電磁界エネルギーを熱変換、或いは反射させる等の特性が向上し、電磁波（ノイズ）を遮蔽する性能が向上する。 In this way, the magnetizations of the plurality of flat magnetic powders M5 are oriented in a desired direction in the in-plane direction PD of the magnetic sheet 15, and the direction of the magnetic field of the magnetic sheet 15 is aligned in the desired direction. It becomes like this. As a result, characteristics such as thermal conversion or reflection of electromagnetic field energy are improved, and the performance of shielding electromagnetic waves (noise) is improved.
　そして、複数の扁平状磁性粉末Ｍ５は、このケース１１に埋め込まれた磁性体シート１５が、３本の端子１３の延出方向に対して、略平行になるように配置されているので、ケース１１内に配設された３本の端子１３に対して、扁平状磁性粉末Ｍ５の長手方向が３本の端子１３の延出方向に対して略平行になるように、並べられ配向するようになる。このことにより、この磁性体シート１５の磁界の向きを端子１３の延出方向に向けて優先的に揃えることができるので、端子１３から出る或いは端子１３に入る電磁波を磁性体シート１５で遮蔽することができる。このようにして、扁平状磁性粉末Ｍ５の長手方向が磁性体シート１５の面内方向ＰＤの所望の方向に揃えられた磁性体シート１５をケース１１に埋め込む構成を採用したので、従来例のような電磁波吸収材９０５を塗布し固化させる方法等と比較して、容易に、磁性体シート１５の磁界の向きを端子１３の延出方向に向けて優先的に揃えることができる。 The plurality of flat magnetic powders M5 are arranged so that the magnetic sheet 15 embedded in the case 11 is substantially parallel to the extending direction of the three terminals 13. 11 so that the longitudinal direction of the flat magnetic powder M5 is aligned and oriented so that the longitudinal direction of the flat magnetic powder M5 is substantially parallel to the extending direction of the three terminals 13. Become. As a result, the direction of the magnetic field of the magnetic sheet 15 can be preferentially aligned in the extending direction of the terminal 13, so that the electromagnetic wave coming out of the terminal 13 or entering the terminal 13 is shielded by the magnetic sheet 15. be able to. As described above, the configuration in which the magnetic sheet 15 in which the longitudinal direction of the flat magnetic powder M5 is aligned in a desired direction in the in-plane direction PD of the magnetic sheet 15 is embedded in the case 11 is used as in the conventional example. Compared with the method of applying and solidifying the electromagnetic wave absorbing material 905, the direction of the magnetic field of the magnetic material sheet 15 can be easily preferentially aligned in the extending direction of the terminals 13.
　また、磁性体シート１５が端子１３を囲うように、上下で挟み込む位置にケース１１内に埋め込まれて配置されているので、端子１３の上下に対して磁性体シート１５が覆うように配置される。このことにより、端子１３から出る或いは端子１３に入る電磁波を、覆うように配置された磁性体シート１５でより遮蔽することができ、ＥＭＣ性能のより良いコネクタ１０１を提供できる。 Further, since the magnetic sheet 15 is embedded in the case 11 so as to surround the terminal 13 so as to surround the terminal 13, the magnetic sheet 15 is disposed so as to cover the upper and lower sides of the terminal 13. . As a result, the electromagnetic wave coming out of the terminal 13 or entering the terminal 13 can be further shielded by the magnetic sheet 15 arranged so as to cover it, and the connector 101 with better EMC performance can be provided.
　次に、本発明の第１実施形態のコネクタ１０１の製造方法について説明する。
　最初に、磁性体シート１５の製造方法について説明する。まず、鉄を主成分とする材料、例えばパーマロイ（Ｆｅ－Ｎｉ合金）を用い、水アトマイズ法により磁性粉末を作製する。なお、水アトマイズ法に限定されず、ガスアトマイズ法、上記合金溶湯から急冷したリボンを粉砕して粉末化する液体急冷法等を用いても良い。また、水アトマイズ法、ガスアトマイズ法、液体急冷法の処理条件については、原料の種類に応じて通常行われる条件を用いることが出来る。そして、得られた磁性粉末を分級して粒度を揃えた後に、遊星撹拌型ボールミル等の装置を用いて、磁性粉末を扁平状に加工する。なお、必要に応じて、磁性粉末の内部応力を緩和させる目的で、扁平状に加工された扁平状磁性粉末Ｍ５にアニール処理を施しても良い。 Next, the manufacturing method of the connector 101 of 1st Embodiment of this invention is demonstrated.
Initially, the manufacturing method of the magnetic material sheet 15 is demonstrated. First, a magnetic powder is prepared by a water atomization method using a material containing iron as a main component, for example, permalloy (Fe—Ni alloy). In addition, it is not limited to the water atomizing method, You may use the gas atomizing method, the liquid quenching method etc. which grind | pulverize and pulverize the ribbon rapidly cooled from the said alloy molten metal. Moreover, about the process conditions of the water atomizing method, the gas atomizing method, and the liquid quenching method, the conditions normally performed according to the kind of raw material can be used. Then, after classifying the obtained magnetic powder to make the particle size uniform, the magnetic powder is processed into a flat shape using an apparatus such as a planetary stirring ball mill. If necessary, the flat magnetic powder M5 processed into a flat shape may be annealed for the purpose of relaxing the internal stress of the magnetic powder.
　次に、磁性体シート１５を構成する合成樹脂Ｐ５と、扁平状磁性粉末Ｍ５とを有して成る混合液（スラリー）を、ドクターブレード装置に供給し、基材（キャリアテープ）を引きながら、ブレードにより混合液を所定厚さで基材上に塗布する。そして、加熱することにより、基材上に合成樹脂Ｐ５と扁平状磁性粉末Ｍ５とから構成される磁性体シート１５が得られる。なお、磁性体シート１５は、この基材と一緒に用いても良いが、本発明の第１実施形態のコネクタ１０１への適用は、肉厚の薄いケース１１の上面１１ｔ及び底面１１ｂに埋め込むため、この基材を除去して、単独で適用した。 Next, a mixed liquid (slurry) comprising the synthetic resin P5 constituting the magnetic sheet 15 and the flat magnetic powder M5 is supplied to the doctor blade device, and the base material (carrier tape) is drawn, The mixed solution is applied to the substrate with a predetermined thickness by a blade. And the magnetic material sheet 15 comprised from the synthetic resin P5 and the flat magnetic powder M5 on a base material is obtained by heating. Although the magnetic sheet 15 may be used together with this base material, the application to the connector 101 of the first embodiment of the present invention is to embed the upper surface 11t and the bottom surface 11b of the thin case 11. The substrate was removed and applied alone.
　図７は、本発明の第１実施形態のコネクタ１０１に用いた磁性体シート１５の磁性率磁気損失μ”の周波数特性を示したグラフである。縦軸に磁性率磁気損失μ”を示し、横軸に周波数を示している。測定は、マイクロストリップラインを設けたプリント配線板（ＰＣＢ）に磁性体シート１５を載置し、信号の入力値及び出力値をネットワークアナライザーにて検出して行った。 FIG. 7 is a graph showing the frequency characteristics of the magnetic susceptibility magnetic loss μ ″ of the magnetic material sheet 15 used in the connector 101 of the first embodiment of the present invention. The frequency is shown on the horizontal axis. The measurement was performed by placing the magnetic sheet 15 on a printed wiring board (PCB) provided with a microstrip line and detecting the input value and output value of the signal with a network analyzer.
　図７に示すように、磁性体シート１５の磁性率磁気損失μ”は、周波数が２０Ｍｈｚから１Ｇｈｚの範囲において、１５以上である。この磁性率磁気損失μ”が大きければ大きいほど、電磁界エネルギーを熱に変換する効率が高く、ひいては電磁波を吸収する電磁波吸収特性が高くなる。このため、磁性体シート１５は、高周波の信号を扱う通信機器や各種電子機器において問題となる高周波側の電磁波（ノイズ）を遮蔽することができる。このことにより、本発明の第１実施形態のコネクタ１０１は、高周波の信号を扱う通信機器や各種電子機器のコネクタに好適に用いることができる。 As shown in FIG. 7, the magnetic susceptibility magnetic loss μ ″ of the magnetic sheet 15 is 15 or more in the frequency range of 20 Mhz to 1 Ghz. Is efficiently converted into heat, and as a result, electromagnetic wave absorption characteristics for absorbing electromagnetic waves are enhanced. For this reason, the magnetic material sheet 15 can shield the electromagnetic waves (noise) on the high frequency side, which is a problem in communication devices and various electronic devices that handle high frequency signals. Accordingly, the connector 101 according to the first embodiment of the present invention can be suitably used for a connector of a communication device or various electronic devices that handle a high-frequency signal.
　次に、コネクタ１０１の製造方法について説明する。先ず、端子１３と磁性体シート１５をケース１１の金型の所望の位置に装着する。そして、ＡＢＳ（アクリロニトリルブタジエンスチレン）、ＰＢＴ（ポリブチレンテレフタレート）等の合成樹脂材料を射出成形する。これにより、磁性体シート１５がケース１１の上面１１ｔ及び底面１１ｂに埋め込まれるとともに、端子１３が保持部１２に保持されたコネクタ１０１を得ることができる。このようにして、磁性体シート１５をインサート成形にて加工して、ケース１１としたので、端子１３から出る或いは端子１３に入る電磁波を遮蔽する磁性体シート１５の扁平状磁性粉末Ｍ５を、端子１３の延出方向に向けて優先的に磁化が配向した位置に容易に配置することができる。 Next, a method for manufacturing the connector 101 will be described. First, the terminal 13 and the magnetic sheet 15 are attached to a desired position of the mold of the case 11. Then, a synthetic resin material such as ABS (acrylonitrile butadiene styrene) or PBT (polybutylene terephthalate) is injection molded. As a result, it is possible to obtain the connector 101 in which the magnetic sheet 15 is embedded in the upper surface 11 t and the bottom surface 11 b of the case 11 and the terminals 13 are held by the holding portion 12. Thus, since the magnetic material sheet 15 is processed by insert molding to form the case 11, the flat magnetic powder M5 of the magnetic material sheet 15 that shields electromagnetic waves that exit from the terminal 13 or enter the terminal 13 It can be easily arranged at a position where magnetization is preferentially oriented in the extending direction of 13.
　さらに、上記製造方法に加え、磁性体シート１５をフープ状にロール加工し、磁性体シート１５を順次インサート成形にて加工して、複数のケース１１を順次作製する工程にした。このため、磁性体シート１５がケース１１の上面１１ｔ及び底面１１ｂに埋め込まれたコネクタ１０１の製造コストを低減することができる。このことにより、端子１３から出る或いは端子１３に入る電磁波を遮蔽することができ、ＥＭＣ性能のより良いコネクタ１０１を安価に得ることができる。 Furthermore, in addition to the manufacturing method described above, the magnetic sheet 15 was rolled into a hoop shape, and the magnetic sheet 15 was sequentially processed by insert molding to sequentially produce a plurality of cases 11. For this reason, the manufacturing cost of the connector 101 in which the magnetic material sheet 15 is embedded in the upper surface 11t and the bottom surface 11b of the case 11 can be reduced. As a result, it is possible to shield the electromagnetic wave that exits from the terminal 13 or enters the terminal 13, and the connector 101 with better EMC performance can be obtained at a low cost.
　以上により、本発明のコネクタ１０１は、端子１３を囲んで収納するケース１１に、端子１３の延出方向に向けて優先的に配向されている磁性体シート１５の扁平状磁性粉末Ｍ５を有しているので、この磁性体シート１５の磁界の向きを端子１３の延出方向に向けて優先的に揃えることができる。このことにより、端子１３から出る或いは端子１３に入る電磁波を磁性体シート１５で遮蔽することができ、ＥＭＣ性能の良いコネクタ１０１を提供できる。 As described above, the connector 101 of the present invention has the flat magnetic powder M5 of the magnetic sheet 15 that is preferentially oriented in the extending direction of the terminal 13 in the case 11 that surrounds and accommodates the terminal 13. Therefore, the magnetic field direction of the magnetic sheet 15 can be preferentially aligned in the extending direction of the terminals 13. As a result, the electromagnetic wave that exits from the terminal 13 or enters the terminal 13 can be shielded by the magnetic sheet 15, and the connector 101 with good EMC performance can be provided.
　また、磁性体シート１５が端子１３を囲うように上下で挟み込む位置にケース１１内に埋め込まれて配置されているので、端子１３の上下に対して磁性体シート１５が覆うように配置される。このことにより、端子１３から出る或いは端子１３に入る電磁波を、覆うように配置された磁性体シート１５でより遮蔽することができ、ＥＭＣ性能のより良いコネクタ１０１を提供できる。 Since the magnetic sheet 15 is embedded in the case 11 at a position sandwiched between the terminals 13 so as to surround the terminal 13, the magnetic sheet 15 is disposed so as to cover the upper and lower sides of the terminal 13. As a result, the electromagnetic wave coming out of the terminal 13 or entering the terminal 13 can be further shielded by the magnetic sheet 15 arranged so as to cover it, and the connector 101 with better EMC performance can be provided.
　また、磁性体シート１５をインサート成形にて加工して、ケース１１としたので、端子１３から出る或いは端子１３に入る電磁波を遮蔽する磁性体シート１５の扁平状磁性粉末Ｍ５を、端子１３の延出方向に向けて優先的に磁化が配向した位置に容易に配置することができる。このことにより、端子１３から出る或いは端子１３に入る電磁波を容易に遮蔽することができ、ＥＭＣ性能のより良いコネクタ１０１を提供できる。 Further, since the magnetic material sheet 15 is processed by insert molding to form the case 11, the flat magnetic powder M 5 of the magnetic material sheet 15 that shields electromagnetic waves that exit from the terminal 13 or enter the terminal 13 is expanded to the terminal 13. It can be easily arranged at a position where magnetization is preferentially oriented in the outgoing direction. As a result, the electromagnetic wave that exits from the terminal 13 or enters the terminal 13 can be easily shielded, and the connector 101 with better EMC performance can be provided.
　また、フープ状にロール加工された磁性体シート１５を用い、複数のケース１１を順次作製する工程にしたので、磁性体シート１５がケース１１の上面１１ｔ及び底面１１ｂに埋め込まれたコネクタ１０１の製造コストを低減することができる。このことにより、端子１３から出る或いは端子１３に入る電磁波を遮蔽することができ、ＥＭＣ性能のより良いコネクタ１０１を安価に得ることができる。 In addition, since the magnetic sheet 15 rolled into a hoop shape is used to sequentially produce a plurality of cases 11, the manufacturing of the connector 101 in which the magnetic sheet 15 is embedded in the upper surface 11t and the bottom surface 11b of the case 11 is performed. Cost can be reduced. As a result, it is possible to shield the electromagnetic wave that exits from the terminal 13 or enters the terminal 13, and the connector 101 with better EMC performance can be obtained at a low cost.
　また、磁性体シート１５の磁性率磁気損失μ”が、周波数２０Ｍｈｚから１Ｇｈｚの範囲において、１５以上であるので、高周波の信号を扱う通信機器や各種電子機器において問題となる高周波側の電磁波（ノイズ）を遮蔽することができる。このことにより、高周波の信号を扱う通信機器や各種電子機器のコネクタに好適に用いることができる。 Further, the magnetic loss magnetic loss μ ″ of the magnetic material sheet 15 is 15 or more in the frequency range from 20 Mhz to 1 Ghz. Therefore, high-frequency electromagnetic waves (noise) that are problematic in communication devices and various electronic devices that handle high-frequency signals. Therefore, it can be suitably used for connectors of communication devices and various electronic devices that handle high-frequency signals.

　さらに、上記成形は、磁性体シート２５を曲げ加工の金型側から吸引し、金型に磁性体シート２５を密着させて行う真空成形の方法を用いている。このことにより、寸法精度の良いケース２１を得ることができるので、磁性体シート２５から構成されるケース２１の電磁波を吸収する電磁波吸収特性を安定させることができる。なお、ケース２１には、図示していないが、相手方コネクタがコネクタ１０２に挿入された際に、相手方コネクタと係合させるための係止構造が別途設けられている。 Further, the above molding uses a vacuum molding method in which the magnetic sheet 25 is sucked from the bending mold side and the magnetic sheet 25 is brought into close contact with the mold. As a result, the case 21 with good dimensional accuracy can be obtained, so that the electromagnetic wave absorption characteristic of absorbing the electromagnetic wave of the case 21 formed of the magnetic sheet 25 can be stabilized. Although not shown, the case 21 is separately provided with a locking structure for engaging with the mating connector when the mating connector is inserted into the connector 102.
　また、ケース２１を構成している磁性体シート２５は、第１実施形態の磁性体シート１５と同様に（図５を参照）、ＡＢＳ（アクリロニトリルブタジエンスチレン）、ＰＰ（ポリプロピレン）等の合成樹脂Ｐ５と、扁平状磁性粉末Ｍ５とから構成される。また、磁性体シート２５は、合成樹脂Ｐ５のマトリックスに、扁平状磁性粉末Ｍ５の長手方向が磁性体シート２５の面内方向ＰＤの所望の方向に揃えた形で、複数の扁平状磁性粉末Ｍ５を並べるように配向させている。このため、複数の扁平状磁性粉末Ｍ５の磁化が磁性体シート２５の面内方向ＰＤの所望の方向に配向するようになり、磁性体シート２５の磁界の向きが、所望の方向に揃うようになる。このことにより、電磁界エネルギーの熱変換、或いは反射させる等の特性が向上し、電磁波（ノイズ）を遮蔽する電磁波吸収性能が向上する。 Further, the magnetic sheet 25 constituting the case 21 is similar to the magnetic sheet 15 of the first embodiment (see FIG. 5), and a synthetic resin P5 such as ABS (acrylonitrile butadiene styrene) or PP (polypropylene). And the flat magnetic powder M5. Further, the magnetic sheet 25 has a plurality of flat magnetic powders M5 in a matrix of the synthetic resin P5 such that the longitudinal direction of the flat magnetic powder M5 is aligned with a desired direction in the in-plane direction PD of the magnetic sheet 25. Are aligned so that they are aligned. For this reason, the magnetization of the plurality of flat magnetic powders M5 is oriented in a desired direction in the in-plane direction PD of the magnetic sheet 25, and the direction of the magnetic field of the magnetic sheet 25 is aligned in the desired direction. Become. Thereby, characteristics such as heat conversion or reflection of electromagnetic field energy are improved, and electromagnetic wave absorption performance for shielding electromagnetic waves (noise) is improved.
　そして、複数の扁平状磁性粉末Ｍ５は、このケース２１を構成している磁性体シート２５が、３本の端子１３の延出方向に対して、略平行になるように配置されているので、ケース２１内に配設された３本の端子１３に対して、扁平状磁性粉末Ｍ５の長手方向が３本の端子１３の延出方向に対して略平行になるように、並べられ配向するようになる。このことにより、この磁性体シート２５の磁界の向きを端子１３の延出方向に向けて優先的に揃えることができるので、端子１３から出る或いは端子１３に入る電磁波を磁性体シート２５で遮蔽することができる。このようにして、扁平状磁性粉末Ｍ５の長手方向が磁性体シート２５の面内方向ＰＤの所望の方向に揃えられた磁性体シート２５をケース２１とした構成を採用したので、従来例のような電磁波吸収材９０５を塗布し固化させる方法等と比較して、容易に、磁性体シート２５の磁界の向きを端子１３の延出方向に向けて優先的に揃えることができる。 And since the magnetic material sheet 25 which comprises this case 21 is arrange | positioned so that the some flat magnetic powder M5 may become substantially parallel with respect to the extension direction of the three terminals 13, The three terminals 13 arranged in the case 21 are arranged and oriented so that the longitudinal direction of the flat magnetic powder M5 is substantially parallel to the extending direction of the three terminals 13. become. As a result, the direction of the magnetic field of the magnetic sheet 25 can be preferentially aligned in the extending direction of the terminal 13, so that the electromagnetic wave exiting from the terminal 13 or entering the terminal 13 is shielded by the magnetic sheet 25. be able to. Thus, since the configuration using the magnetic sheet 25 in which the longitudinal direction of the flat magnetic powder M5 is aligned in a desired direction in the in-plane direction PD of the magnetic sheet 25 as the case 21 is adopted, as in the conventional example Compared with the method of applying and solidifying the electromagnetic wave absorbing material 905, the direction of the magnetic field of the magnetic material sheet 25 can be easily preferentially aligned in the extending direction of the terminals 13.
　また、磁性体シート２５が端子１３の周囲を囲うように、配置されているので、端子１３から出る或いは端子１３に入る電磁波を、端子１３を覆うように配置された磁性体シート２５でより遮蔽することができ、ＥＭＣ性能のより良いコネクタ１０２を提供できる。 Further, since the magnetic material sheet 25 is arranged so as to surround the terminal 13, the electromagnetic wave coming out from the terminal 13 or entering the terminal 13 is further shielded by the magnetic material sheet 25 arranged so as to cover the terminal 13. The connector 102 with better EMC performance can be provided.
　以上により、本発明のコネクタ１０２は、端子１３を囲んで収納するケース２１に、端子１３の延出方向に向けて優先的に配向されている磁性体シート２５の扁平状磁性粉末Ｍ５を有しているので、この磁性体シート２５の磁界の向きを端子１３の延出方向に向けて優先的に揃えることができる。このことにより、端子１３から出る或いは端子１３に入る電磁波を磁性体シート２５で遮蔽することができ、ＥＭＣ性能の良いコネクタ１０２を提供できる。 As described above, the connector 102 of the present invention has the flat magnetic powder M5 of the magnetic sheet 25 that is preferentially oriented in the extending direction of the terminal 13 in the case 21 that surrounds and accommodates the terminal 13. Therefore, the direction of the magnetic field of the magnetic sheet 25 can be preferentially aligned in the extending direction of the terminals 13. As a result, the electromagnetic wave coming out of the terminal 13 or entering the terminal 13 can be shielded by the magnetic material sheet 25, and the connector 102 with good EMC performance can be provided.
　また、磁性体シート２５が端子１３の周囲を囲うように、配置されているので、端子１３から出る或いは端子１３に入る電磁波を、端子１３を覆うように配置された磁性体シート２５でより遮蔽することができ、ＥＭＣ性能のより良いコネクタ１０２を提供できる。 Further, since the magnetic material sheet 25 is arranged so as to surround the terminal 13, the electromagnetic wave coming out from the terminal 13 or entering the terminal 13 is further shielded by the magnetic material sheet 25 arranged so as to cover the terminal 13. The connector 102 with better EMC performance can be provided.
　また、磁性体シート２５を加熱軟化させて成形し、ケース２１としたので、端子１３から出る或いは端子１３に入る電磁波を遮蔽する磁性体シート２５を、端子１３の延出方向に向けて優先的に及び端子１３を囲うように容易に配置することができる。このことにより、端子１３から出る或いは端子１３に入る電磁波を容易に遮蔽することができ、ＥＭＣ性能のより良いコネクタ１０２を提供できる。 In addition, since the magnetic sheet 25 is softened by heating and formed into the case 21, the magnetic sheet 25 that shields electromagnetic waves that exit from the terminal 13 or enter the terminal 13 is preferentially directed toward the extending direction of the terminal 13. It can be easily arranged so as to surround the terminals 13. As a result, the electromagnetic wave that exits from the terminal 13 or enters the terminal 13 can be easily shielded, and the connector 102 with better EMC performance can be provided.
