然し乍ら、特許文献１や特許文献２に記載のものは、マグネットを組設したものであるが、一般の電気機器に用いられているコネクターであり、比較的大きいことから接続のための強力な磁着力を有した大きさや複数のマグネットを組み込むスペースを有しているものであるが、マグネットより吸着される金属等の異物の侵入を防ぐ構造には成っておらず、又、特許文献３に記載のものは、差込口に可撓性を有したシャッターは備えているものの、接続するためのマグネットは備えていないものである。   However, the ones described in Patent Document 1 and Patent Document 2 are ones in which a magnet is assembled, but are connectors used in general electric equipment and are relatively large, so that a strong magnetic force for connection is obtained. Although it has a size that has an adhesion force and a space for incorporating a plurality of magnets, it does not have a structure that prevents intrusion of foreign substances such as metal adsorbed by the magnets, and is described in Patent Document 3. Although the thing provided with the shutter which has flexibility in the insertion port, the thing for which the magnet for connecting is not provided.

つまり、一般の家庭電器製品の電源用として用いられているコネクターは比較的大きなプラグや、コンセント、プラグ受けが用いられているために充分に磁着力を有した大きさや、複数のマグネットを組み込むことが可能であるが、携帯電話とその充電器との接続、コードレスヘッドホンの充電器との接続、ノート式パーソナルコンピュータの電源コードとを接続するような超小型のプラグ受けとプラグとのコネクターにおいては、接続端子が多芯である上に、ケーシングか小さいために充分な磁着力を有したマグネットを組込スペースが無かった。   In other words, connectors used for the power supply of general household appliances use relatively large plugs, outlets, and plug receptacles, so that they have sufficient magnetizing force and incorporate multiple magnets. It is possible to connect a mobile phone to its charger, a cordless headphone charger, a laptop personal computer power cord and an ultra-small plug receptacle and plug connector. In addition to the multi-core connection terminals, there was no space for installing a magnet with sufficient magnetic adhesion because the casing was small.

更には、近年、携帯電話やコードレスヘッドホン、ノート式パーソナルコンピュータは年々小型化、軽量化され、机等の上に置いて充電や使用をすることから、不用意にコードを引っ張ってしまい床に落下させて高価な本体そのものを壊してしまい記憶させたデータが飛んでしまうような取り返しのできないような事故も頻発している実情である。   Furthermore, in recent years, cell phones, cordless headphones, and notebook personal computers have become smaller and lighter year by year, and since they are placed on a desk or the like for charging or use, they accidentally pulled the cord and dropped it on the floor. In fact, accidents that cannot be recovered, such as destroying the expensive main body itself and losing the stored data, are frequently occurring.

本発明の小型マグネットコネクターは、前述の課題に鑑み、鋭意研鑽の結果、小型のプラグ受けとプラグから成るコネクターであって、プラグ受けは先端面にプラグの嵌着部を挿通させる開口凹陥部を形成したプラグ受け本体と、プラグ受け本体の略中央に配設されたマグネットと、マグネットの両側に接触させると共に開口凹陥部の底面を貫通させた一対の磁性板と、一対の磁性板に平行させて開口凹陥部の底面を夫々摺動自在に貫通させた複数のプラグ受け側接点部材と、プラグ受け側接点部材を固定させた板状バネ体と、プラグは開口凹陥部に嵌入する嵌着部を突設したプラグ本体と、プラグ本体に先端に露出させて一対の磁性板と当接するように埋設した一対の吸着板と、一対の吸着板に平行させて嵌着部の先端に露出させプラグ受け側接点部材と当接するプラグ側接点部材とを備えたものであり、更に、プラグ受けの開口凹陥部の開口端辺に相対的にヒンジ部を介装して枢動可能に装着した一対のシャッターと、シャッターを絶えず閉鎖位置に維持するように弾性を付与するコイルスプリングとを備えたものであり、更には、プラグ本体にＬＥＤチップを埋設して、ＬＥＤチップの点灯により磁性板と吸着板とが接触することにより通電状態が確認できる構造としたものである。   The small magnet connector of the present invention is a connector composed of a small plug receiver and a plug as a result of diligent research in view of the above-mentioned problems, and the plug receiver has an opening recessed portion through which the plug fitting portion is inserted into the distal end surface. The formed plug receiving body, a magnet disposed substantially at the center of the plug receiving body, a pair of magnetic plates contacting both sides of the magnet and penetrating the bottom surface of the opening recess, and parallel to the pair of magnetic plates A plurality of plug receiving side contact members slidably penetrating the bottom surface of the opening recessed portion, a plate spring body to which the plug receiving side contact member is fixed, and a fitting portion in which the plug is fitted into the opening recessed portion.

更には、プラグ受け本体１１の開口凹陥部１２は未使用状態では一対のシャッター１７により閉ざされており、塵芥や不用意に侵入物が侵入しないようにしているもので、プラグ受け本体１１の開口凹陥部１２にプラグ本体２１の嵌着部２１ａを一対のシャッター１７の夫々のコイルスプリング１８の弾性に抗して挿通させるもので、以後は前述と重複するので詳述は省略するものである。   Furthermore, the opening recess 12 of the plug receiving body 11 is closed by a pair of shutters 17 when not in use so that dust and inadvertent objects do not intrude. The fitting portion 21a of the plug main body 21 is inserted into the recessed portion 12 against the elasticity of the coil springs 18 of the pair of shutters 17, and since this overlaps with the above description, the detailed description is omitted.

本発明の小型マグネットコネクターは、携帯電話とその充電器との接続、コードレスヘッドホンの充電器との接続、ノート式パーソナルコンピュータの電源コードとを接続するような超小型のコネクターに、接続用のマグネットと塵芥等の侵入を防ぐシャッターを備えたものであり、電源と接続中に不用意にコードを引っ張ったような場合でも、磁着した接続部が外れ電気機器本体の落下等を防止すると共に、磁気を有する開口部に磁着し易い塵芥物の侵入を防止する小型マグネットコネクターを提供するものである。   The small magnet connector of the present invention is a magnet for connection to an ultra-compact connector that connects a mobile phone and its charger, a cordless headphone charger, and a power cord of a notebook personal computer. And a shutter that prevents the intrusion of dust, etc., even if the cord is accidentally pulled while connected to the power supply, the magnetically attached connection part will come off to prevent the electric device body from falling, etc. It is an object of the present invention to provide a small magnet connector that prevents the entry of dust that easily adheres to an opening having magnetism.
