Description

本発明は、工作機械等に使用される電気丸形コネクタに関するものであり、特にコンタクトとシェルとのアース構造に関するものである。   The present invention relates to an electric round connector used for a machine tool or the like, and more particularly to a ground structure of a contact and a shell.

電気丸形コネクタ１においては、保護回路接続のために、コンタクト２４とシェル２８との間のアースをとる必要があり、アースを取るために一般的に別部品のアースラグ６０を使用している。以下、図４に基づいて、従来のアースラグ６０の構造と該アースラグ６０を用いたアース構造について説明する。図４は従来のアースラグの斜視図である。まず、従来のアースラグ６０の構造について説明する。従来のアースラグ６０は、図４のように略円筒状をしており、この円筒状の内部にコンタクト２４が装着されることになる。アースラグ６０には、コンタクト２４と接触するために、円筒状の内部に湾曲した少なくとも１以上の接触片１２が設けられている。該コンタクト２４との安定した接触を考えると、２つ程度がよい。また、該アースラグ６０には、該シェル２８と接触するために、インシュレータ２２に装着した際に該シェル２８に接触できる位置で外側方向に突出した接触部６２が設けられている。該アースラグ６０は金属製であり、公知技術のプレス加工によって製作されており、まず板状片の材料を所定の形状に抜き、次に前記接触片１２や前記接触部６２を曲げ加工や切り起こし等で作成し、その後複数回の曲げ加工を繰り返すことで円筒状にしている。   In the electrical circular connector 1, it is necessary to ground between the contact 24 and the shell 28 in order to connect the protection circuit, and a separate ground lug 60 is generally used for grounding. Hereinafter, the structure of the conventional ground lug 60 and the ground structure using the ground lug 60 will be described with reference to FIG. FIG. 4 is a perspective view of a conventional earth lug. First, the structure of the conventional earth lug 60 will be described. The conventional earth lug 60 has a substantially cylindrical shape as shown in FIG. 4, and the contact 24 is mounted inside the cylindrical shape. The ground lug 60 is provided with at least one or more contact pieces 12 curved in a cylindrical shape so as to come into contact with the contact 24. Considering the stable contact with the contact 24, about two are preferable. In addition, the ground lug 60 is provided with a contact portion 62 that protrudes outward in a position where it can come into contact with the shell 28 when it is attached to the insulator 22 in order to come into contact with the shell 28. The earth lug 60 is made of metal and is manufactured by a known press process. First, the material of the plate-like piece is drawn into a predetermined shape, and then the contact piece 12 and the contact portion 62 are bent or cut and raised. It is made into a cylindrical shape by repeating the bending process several times after that.

次に、該アースラグ６０を用いたアース構造について説明する。上述したように、該アースラグ６０と該コンタクト２４は、コンタクト２４をアースラグ６０に装着すると、アースラグ６０の接触片１２と接触する構造になっている。該アースラグ６０と該シェル２８との接触構造は、該アースラグ６０を該インシュレータ２２に挿入すると、外側方向に突出したアースラグの接触部６２がシェル２８に接触するようになっている。該コンタクト２４と該シェル２８との接触構造は、インシュレータ２２に挿入された状態のアースラグ６０にコンタクト２４を装着することで行っている。   Next, a ground structure using the ground lug 60 will be described. As described above, the ground lug 60 and the contact 24 are configured to contact the contact piece 12 of the ground lug 60 when the contact 24 is attached to the ground lug 60. The contact structure between the ground lug 60 and the shell 28 is such that when the ground lug 60 is inserted into the insulator 22, the contact portion 62 of the ground lug protruding outwardly contacts the shell 28. The contact structure between the contact 24 and the shell 28 is achieved by attaching the contact 24 to a ground lug 60 inserted into the insulator 22.

該シェル２８の表面には、耐環境性向上のために、一般的にこの分野ではクロメート処理の表面処理を行っている。その為、従来の該アースラグ６０と該シェル２８との接触構造においては、予めアースラグ６０の接触部６２と接触する位置の該シェル２８の表面処理を取り除く必要が生じ、取り除く手間が掛かり、取り除く正確な位置が解り難いと言った解決すべき課題があった。また、表面処理を取り除く位置を間違えたりすると、アース出来ないといったことも発生していた。   In order to improve the environmental resistance, the surface of the shell 28 is generally subjected to a chromate treatment in this field. For this reason, in the conventional contact structure between the earth lug 60 and the shell 28, it is necessary to remove the surface treatment of the shell 28 at a position in contact with the contact portion 62 of the earth lug 60 in advance. There was a problem to be solved that said it was difficult to understand the correct position. In addition, if the position for removing the surface treatment is mistaken, grounding cannot be performed.

本発明は、このような従来の問題点に鑑みてなされたもので、該シェル２８の表面処理を予め取り除くことなく、安定した該アースラグ１０と該シェル２８のアース構造を得ることのできる電気丸形コネクタ１を提供せんとするものである。   The present invention has been made in view of such conventional problems, and an electric circle that can obtain a stable grounding structure of the earth lug 10 and the shell 28 without removing the surface treatment of the shell 28 in advance. The connector 1 is intended to be provided.

上記目的は、所要数のコンタクト２４と、このコンタクト２４を保持・固定するインシュレータ２２と、このインシュレータ２２を覆うように配置されるシェル２８と、このシェル２８及び１本のコンタクト２４と接触する構造のアースラグ１０とからなる電気丸形コネクタ１において、前記アースラグ１０には、１本の該コンタクト２４との接触手段（固定手段）を有すると共に、前記シェル２８方向に屈曲した弾性を有する弾性片１４を設けることにより達成できる。前記接触手段（固定手段）としては、該アースラグ１０を、１本の該コンタクト２４を覆うような弾性を有した略筒状にする。このように筒状にすることで、容易にコンタクト２４に該アースラグ１０を装着し、接触することができる。また、前記弾性片１４の自由端側に少なくと１個以上の角部１８，２０を設け、かつ、自由端側の近傍に少なくとも１以上の折曲げ部１６を設けたほうがよい。このように前記角部１８，２０と折曲げ部１６を設けることで確実に該シェル２８の表面処理を取り除く（削り取る）ことができる。なお、該アースラグ１０をインシュレータ２２に装着と同時に前記角部１８，２０で、該シェル２８の表面処理を取り除くようになり、該アースラグ１０を用いて、１本の該コンタクト２４と該シェル２８とのアース構造を取ることができるようにする。弾性片１４の最初の角度が１７〜２２゜で、前記折曲げ部１６からの角度が４０〜６５゜にする。即ち、折曲げ部１６からの角度を１８〜４８゜大きくする。このようにすることで、確実に該シェル２８の表面処理を削り取れるようにしている。折曲げ部１６からの大きくする角度が１８゜以下では内側に倒れ込むだけで削り取ることが出来ず、４８゜以上だとアースラグ１０が挿入できない。   The purpose is to provide a required number of contacts 24, an insulator 22 that holds and fixes the contacts 24, a shell 28 that is arranged to cover the insulator 22, and a structure that contacts the shell 28 and one contact 24. In the electric circular connector 1 comprising the earth lug 10, the earth lug 10 has a contact means (fixing means) with one contact 24, and an elastic piece 14 having elasticity bent in the direction of the shell 28. Can be achieved. As the contact means (fixing means), the ground lug 10 is formed into a substantially cylindrical shape having elasticity so as to cover one contact 24. By making it cylindrical like this, the ground lug 10 can be easily attached to and brought into contact with the contact 24. Further, it is preferable to provide at least one or more corners 18 and 20 on the free end side of the elastic piece 14 and at least one or more bent portions 16 in the vicinity of the free end side. Thus, by providing the corner portions 18 and 20 and the bent portion 16, the surface treatment of the shell 28 can be surely removed (scraped). At the same time that the earth lug 10 is mounted on the insulator 22, the surface treatment of the shell 28 is removed at the corners 18, 20. Using the earth lug 10, the contact 24, the shell 28, To be able to take the earth structure. The initial angle of the elastic piece 14 is 17 to 22 °, and the angle from the bent portion 16 is 40 to 65 °. That is, the angle from the bent portion 16 is increased by 18 to 48 degrees. In this way, the surface treatment of the shell 28 can be surely removed. If the angle from the bent portion 16 is 18 ° or less, it cannot be scraped simply by falling inward, and if it is 48 ° or more, the earth lug 10 cannot be inserted.

該コンタクト２４に装着した該アースラグ１０を該インシュレータ２２に挿入すると、アースラグ１０の角部１８，２０がシェル２８に押し付けられ、シェル２８の表面処理を削り取りながら挿入される。   When the earth lug 10 attached to the contact 24 is inserted into the insulator 22, the corners 18 and 20 of the earth lug 10 are pressed against the shell 28 and inserted while scraping the surface treatment of the shell 28.

以上の説明から明らかなように、本発明に係る電気丸形コネクタ１によると、次のような優れた効果が得られる。
（１）前記アースラグ１０には前記シェル２８方向に屈曲した弾性を有する弾性片１４が設けられているので、インシュレータ２２に挿入された状態のアースラグ１０をシェル２８に挿入する際に容易に接触できる。
（２）該アースラグ１０は１本の該コンタクト２４を覆うような弾性を有した略筒状になっていおるので、容易にコンタクト２４を該アースラグ１０に装着し、接触することができる。
（３）前記弾性片１４の自由端側に少なくと１個以上の角部１８，２０を設け、かつ、自由端側の近傍に少なくとも１以上の折曲げ部１６を設けているので、確実に該シェル２８の表面処理を取り除く（削り取る）ことができ、安定したアース構造を得ることができる。
（４）該アースラグ１０をインシュレータ２２に装着と同時に前記角部１８，２０で、該シェル２８の表面処理を取り除くようになり、該アースラグ１０を用いて、１本の該コンタクト２４と該シェル２８とのアース構造を取ることができるようなったので、予め表面処理を取り除くことがなく、容易にアース構造が得られるようになった。 As is clear from the above description, according to the electrical circular connector 1 according to the present invention, the following excellent effects can be obtained.
(1) Since the ground lug 10 is provided with the elastic piece 14 having elasticity bent in the direction of the shell 28, the ground lug 10 inserted in the insulator 22 can be easily contacted when inserted into the shell 28. .
(2) Since the ground lug 10 has a substantially cylindrical shape having elasticity so as to cover one contact 24, the contact 24 can be easily attached to and contacted with the ground lug 10.
(3) Since at least one or more corners 18 and 20 are provided on the free end side of the elastic piece 14 and at least one or more bent portions 16 are provided near the free end side. The surface treatment of the shell 28 can be removed (scraped), and a stable ground structure can be obtained.
(4) At the same time that the earth lug 10 is mounted on the insulator 22, the surface treatment of the shell 28 is removed at the corner portions 18, 20, and the single contact 24 and the shell 28 are removed using the earth lug 10. The ground structure can be easily obtained without removing the surface treatment in advance.

FIG. 1A is a perspective view of the ground lug of the present invention viewed from the contact mounting direction, and FIG. 1B is a perspective view of the ground lug of the present invention viewed from the opposite side of the contact mounting direction. FIG. 2A is a plan view of an electrical circular connector using the ground lug of the present invention, and FIG. 2B is a cross-sectional side view of the electrical circular connector using the ground lug of the present invention. FIG. 3 is an enlarged plan view of a portion where the earth lug of the present invention is inserted. The electrical circular connector 1 mainly includes a contact 24, an insulator 22, a shell 28, and a ground lug 10.

まず、本発明のポイント部分であるアースラグ１０について説明する。該アースラグ１０は、従来同様に金属製であり、公知技術のプレス加工によって製作され、材質としてはバネ性が要求されるので、黄銅やリン青銅やベリリウム銅などを挙げることができる。該アースラグ１０の役割は、該コンタクト２４と該シェル２８とのアースを取るためのものである。該アースラグ１０の形状としては、本実施例では略円筒状にしたが上記役割を満足できれば如何なる形状でもよい。図示はしないが、例えば箱型や楕円などでもよい。   First, the earth lug 10 which is the point part of this invention is demonstrated. The earth lug 10 is made of metal as in the prior art, and is manufactured by a known press process. The material is required to have a spring property, and examples thereof include brass, phosphor bronze, and beryllium copper. The role of the ground lug 10 is for grounding the contact 24 and the shell 28. The shape of the earth lug 10 is substantially cylindrical in this embodiment, but may be any shape as long as the above role can be satisfied. Although not shown, for example, a box shape or an ellipse may be used.

該アースラグ１０には、該コンタクト２４との接触手段（固定手段）として、従来のように、円筒状の内部にコンタクト２４が装着された際に、コンタクト２４と接触するための円筒状の内部に湾曲した少なくとも１以上の接触片１２が設けられている。該コンタクト２４との安定した接触を考えると、接触片１２は２つ程度がよい。前記円筒状の内部形状は、コンタクト２４の外形形状に沿った形状にしている。また、該アースラグ１０には、該シェル２８方向に屈曲した弾性を有する弾性片１４が設けられており、この弾性片１４が該シェル２８の内側面と接触する部分であり、確実に内側面に接触するように、前記弾性片１４の自由端側に少なくと１個以上の角部１８，２０を設け、かつ、自由端側の近傍に少なくとも１以上の折曲げ部１６を設けている。該アースラグ１０が該インシュレータ２２の挿入される前の形状は、図１のようになっており、前記弾性片１４は外側に幾分開いた状態である。幾分開かせることで、該シェル２８に装着した際に圧力が掛かるようにしている。   As a contact means (fixing means) for contact with the contact 24, the ground lug 10 has a cylindrical interior for contacting the contact 24 when the contact 24 is mounted inside the cylindrical interior as in the prior art. At least one or more contact pieces 12 that are curved are provided. Considering stable contact with the contact 24, about two contact pieces 12 are preferable. The cylindrical internal shape is a shape along the outer shape of the contact 24. Further, the ground lug 10 is provided with an elastic piece 14 having elasticity bent in the direction of the shell 28. The elastic piece 14 is a portion in contact with the inner side surface of the shell 28. At least one or more corners 18 and 20 are provided on the free end side of the elastic piece 14 so as to be in contact with each other, and at least one bent portion 16 is provided in the vicinity of the free end side. The shape of the earth lug 10 before the insulator 22 is inserted is as shown in FIG. 1, and the elastic piece 14 is somewhat opened outward. By opening it somewhat, pressure is applied when the shell 28 is attached.

本実施例では、前記折曲げ部１６は１箇所に設けてあり、ほぼ中央部付近から更に外側に開くようにしている。即ち、弾性片１４の屈曲角度を中央部付近から変えており、本実施例では最初の角度が１７〜２２゜で、前記折曲げ部１６からの角度が４０〜６５゜にしている。折曲げ部１６からの角度を１８〜４８゜大きくすることで、確実に該シェル２８の表面処理を削り取れるようにしている。折曲げ部１６からの大きくする角度が１８゜以下では内側に倒れ込むだけで削り取ることが出来ず、４８゜以上だとアースラグ１０が挿入できない。本実施例では、前記角部１８，２０を前記弾性片１４の自由端側に２箇所（角部Ａ１８及び角部Ｂ２０）設けられており、実際にはこの角部１８，２０が該アースラグ１０を該シェル２８に装着した際にシェル２８の内側壁部の表面処理を削り取る部分である。該シェル２８の表面処理を削り取ることが出来れば１箇所でも十分であるが、シェル２８の強度とアースラグ１０の強度を考えた場合の角部１８，２０の摩耗を考慮して確実性を向上させるために２箇所にした。角部Ａ１８と角部Ｂ２０の突出量との寸法関係はほぼ同一の寸法にしており、まず角部Ｂ２０でシェル２８の表面処理を削っていき、角部Ｂ２０が摩耗して該シェル２８の表面処理を削れなくなった場合には直ぐに角部Ａ１８で表面処理を削るようにするためである。上述のように、前記角部１８，２０と前記折曲げ部１６を双方とも設けることで確実に該シェル２８の表面処理を取り除く（削り取る）ことができるようになっており、上記折曲げ部１６からの角度や角部１８，２０の突出量は上記役割を考慮して適宜設計する。なお、該アースラグ１０は、第一に板状片の材料を所定の形状に抜き、次に前記接触片１２や折曲げ部１６を曲げ加工等で作成し、その後複数回の曲げ加工を繰り返すことで円筒状にし弾性片１４を作成している。   In the present embodiment, the bent portion 16 is provided at one place, and is further opened outward from the vicinity of the central portion. That is, the bending angle of the elastic piece 14 is changed from the vicinity of the central portion. In this embodiment, the initial angle is 17 to 22 °, and the angle from the bent portion 16 is 40 to 65 °. By increasing the angle from the bent portion 16 by 18 to 48 °, the surface treatment of the shell 28 can be surely removed. If the angle from the bent portion 16 is 18 ° or less, it cannot be scraped simply by falling inward, and if it is 48 ° or more, the earth lug 10 cannot be inserted. In the present embodiment, the corner portions 18 and 20 are provided at two locations (corner portion A 18 and corner portion B 20) on the free end side of the elastic piece 14, and actually the corner portions 18 and 20 are provided in the ground lug 10. This is a part for scraping off the surface treatment of the inner wall portion of the shell 28 when the shell 28 is attached to the shell 28. If the surface treatment of the shell 28 can be scraped off, one location is sufficient, but the reliability is improved in consideration of the wear of the corners 18 and 20 when the strength of the shell 28 and the strength of the earth lug 10 are considered. For this reason, it was made two places. The dimensional relationship between the protrusions of the corner A18 and the corner B20 is substantially the same. First, the surface treatment of the shell 28 is shaved at the corner B20, and the surface of the shell 28 is worn by the corner B20. This is because the surface treatment is immediately cut at the corner A18 when the treatment cannot be cut. As described above, by providing both the corner portions 18 and 20 and the bent portion 16, the surface treatment of the shell 28 can be surely removed (scraped). The angle from the angle and the protruding amount of the corner portions 18 and 20 are appropriately designed in consideration of the above role. The ground lug 10 is obtained by first extracting the material of the plate-shaped piece into a predetermined shape, then forming the contact piece 12 and the bent portion 16 by bending or the like, and then repeating the bending process a plurality of times. Thus, the elastic piece 14 is formed in a cylindrical shape.

ここで、該コンタクト２４と該シェル２８とのアース構造について説明する。まず、該アースラグ１０は、該インシュレータ２２に圧入等により固定され、アースラグ１０が挿入されたインシュレータ２２は該シェル２８に装着される。この際に、アースラグ１０の角部１８，２０で該シェル２８の表面処理を削っていくことで、アースラグ１０とシェル２８は接触した状態になる。更に、この状態のアースラグ１０にコンタクト２４を装着すると、アースラグ１０の接触片１２とコンタクト２４が接触する。すなわち、コンタクト２４とシェル２８は、アースラグ１０を介して接触していることになり、アースしていることになる。   Here, the ground structure between the contact 24 and the shell 28 will be described. First, the ground lug 10 is fixed to the insulator 22 by press fitting or the like, and the insulator 22 into which the ground lug 10 is inserted is attached to the shell 28. At this time, the ground lug 10 and the shell 28 are in contact with each other by cutting the surface treatment of the shell 28 at the corners 18 and 20 of the ground lug 10. Further, when the contact 24 is attached to the ground lug 10 in this state, the contact piece 12 of the ground lug 10 and the contact 24 come into contact with each other. That is, the contact 24 and the shell 28 are in contact with each other via the ground lug 10 and are grounded.

次に、インシュレータ２２について説明する。このインシュレータ２２は電気絶縁性のプラスチックであり、公知技術の射出成形等により製作され、材質としては寸法安定性やコストや絶縁性・難燃性等が要求されるのでＰＢＴ（ポリブチレンテレフタレート）やＰＥＴ（ポリエチレンテレフタレート）やＰＰＳ（ポリフェニレンサルファイド）やＬＣＰ（液晶ポリマー）等を挙げることができる。該インシュレータ２２には、所要数のコンタクト２４が挿入される挿入孔が設けられており、この挿入孔のうち必要数が該アースラグ１０が挿入できる構造の挿入孔にしている。   Next, the insulator 22 will be described. The insulator 22 is an electrically insulating plastic, and is manufactured by a known technique such as injection molding. Since the material is required to have dimensional stability, cost, insulation, flame retardancy, etc., PBT (polybutylene terephthalate) or Examples thereof include PET (polyethylene terephthalate), PPS (polyphenylene sulfide), and LCP (liquid crystal polymer). The insulator 22 is provided with an insertion hole into which a required number of contacts 24 are inserted. The required number of the insertion holes is an insertion hole in which the ground lug 10 can be inserted.

次に、コンタクト２４について説明する。該コンタクト２４は金属製であり、公知技術のプレス加工によって製作され、材質としては導電性やバネ性やが要求されるので、黄銅やリン青銅やベリリウム銅などを挙げることができる。該コンタクト２４は相手コネクタと接触する接触部とインシュレータ２２に固定される固定部とケーブルに接続する接続部とから構成される。該アースラグ１０にコンタクト２４を装着した場合には、コンタクト２４の最外径部分にアースラグ１０の接触片１２が接触することになる。   Next, the contact 24 will be described. Since the contact 24 is made of metal and is manufactured by a known press working, and the material is required to be conductive or springy, examples thereof include brass, phosphor bronze, and beryllium copper. The contact 24 includes a contact portion that contacts the mating connector, a fixed portion that is fixed to the insulator 22, and a connection portion that is connected to the cable. When the contact 24 is attached to the ground lug 10, the contact piece 12 of the ground lug 10 contacts the outermost diameter portion of the contact 24.

最後に、シェル２８について説明する。シェル２８は金属製であり、公知技術の鋳造等により製作され、材質としては強度やコストや加工性等を考慮して亜鉛ダイキャストやアルミダイキャスト等を挙げることができる。該シェル２８には、該インシュレータ２２が挿入される嵌入孔が設けられ、固定用止め輪等によって固定されている。また、該シェル２８には、筐体等に取付けるためのフランジ部２８が設けられ、本実施例では前記フランジ部２８にネジの取付孔が設けられている。   Finally, the shell 28 will be described. The shell 28 is made of metal and is manufactured by a known technique such as casting, and examples of the material include zinc die cast and aluminum die cast in consideration of strength, cost, workability, and the like. The shell 28 is provided with a fitting hole into which the insulator 22 is inserted, and is fixed by a retaining ring for fixing. The shell 28 is provided with a flange portion 28 for attachment to a housing or the like. In this embodiment, the flange portion 28 is provided with a screw attachment hole.
