　特許文献１に開示された同軸コネクタ５００には、第１コネクタ５００Ａと第２コネクタ５００Ｂと接続したときの、高さ寸法が大きいという問題があった。以下、その理由について説明する。 The coaxial connector 500 disclosed in Patent Document 1 has a problem that the height dimension is large when connected to the first connector 500A and the second connector 500B. The reason will be described below.
　図９（Ａ）に示すように、同軸コネクタ５００の第２コネクタ５００Ｂには、円筒状の外部導体５５の内周であって、スカート部５７の付根部分に、ロック爪５８が形成されている。このロック爪５８は、通常、外部導体５５を円筒状に成形した後に、プレス加工によって形成される。そのため、外部導体５５のロック爪５８を形成した部分の外周には、高さ方向に一定の寸法を備えた溝５８ａが形成されており、ロック爪５８は、高さ方向に大きな寸法を備えたものになっていた。そして、第２コネクタ５００Ｂは、外部導体５５の内周に、高さ方向に大きな寸法を備えたロック爪５８が形成されているため、外部導体５５自体の高さ寸法が大きかった。その結果、同軸コネクタ５００は、第２コネクタ５００Ｂ自体の高さ寸法が大きく、更には、第１コネクタ５００Ａと第２コネクタ５００Ｂと接続したときの高さ寸法も大きかった。 As shown in FIG. 9A, the second connector 500 </ b> B of the coaxial connector 500 has a lock claw 58 formed on the inner periphery of the cylindrical outer conductor 55 and at the root of the skirt portion 57. . The lock claw 58 is usually formed by pressing after forming the outer conductor 55 into a cylindrical shape. Therefore, a groove 58a having a constant dimension in the height direction is formed on the outer periphery of the portion of the outer conductor 55 where the lock claw 58 is formed, and the lock claw 58 has a large dimension in the height direction. It was a thing. In the second connector 500B, the lock claw 58 having a large dimension in the height direction is formed on the inner periphery of the external conductor 55, and thus the height dimension of the external conductor 55 itself is large. As a result, the coaxial connector 500 has a large height dimension of the second connector 500B itself, and also has a large height dimension when connected to the first connector 500A and the second connector 500B.
　また、同軸コネクタ５００には、第２コネクタ５００Ｂのスカート部５７を、あまり長くできないという問題もあった。第２コネクタ５００Ｂのスカート部５７は、第１コネクタ５００Ａと第２コネクタ５００Ｂとを接続する際の位置を合せるためのガイドであるため、長いほど、いわゆる誘い込み量が大きくなり、第１コネクタ５００Ａと第２コネクタ５００Ｂとの位置合わせが容易になる。しかしながら、スカート部５７を長くすると、更に第２コネクタ５００Ｂの高さ寸法が大きくなってしまうため、同軸コネクタ５００には、スカート部５７を、あまり長くできないという問題があった。その結果、同軸コネクタ５００は、第１コネクタ５００Ａと第２コネクタ５００Ｂとの位置合わせが難しかった。 Also, the coaxial connector 500 has a problem that the skirt portion 57 of the second connector 500B cannot be made too long. Since the skirt portion 57 of the second connector 500B is a guide for aligning the position when the first connector 500A and the second connector 500B are connected, the longer the skirt portion 57, the larger the so-called lead-in amount. Positioning with the second connector 500B is facilitated. However, if the skirt portion 57 is lengthened, the height dimension of the second connector 500B is further increased. Therefore, the coaxial connector 500 has a problem that the skirt portion 57 cannot be made too long. As a result, it is difficult for the coaxial connector 500 to align the first connector 500A and the second connector 500B.
　本発明は、上述した従来の問題を解決するためになされたものであり、その手段として本発明の同軸コネクタは、外部導体と、センターピンまたはソケットとを備えた第１コネクタと、外部導体と、ソケットまたはセンターピンとを備えた第２コネクタと、を備え、第１コネクタの外部導体と第２コネクタの外部導体とを接続するとともに、第１コネクタのセンターピンと第２コネクタのソケットとを接続するか、または、第１コネクタのソケットと第２コネクタのセンターピンとを接続して使用するものであって、第１コネクタの外部導体は、第２コネクタが接続される側の主面に設けられた平面部と、平面部に形成された円形の開口とを備え、開口には、開口の中心軸に近づくほど平面部から離れる方向に傾斜した、第１コネクタと第２コネクタとを接続する際に位置を合せるためのガイドとなるテーパー部が形成され、テーパー部の先端にロック爪が形成され、第２コネクタの外部導体は円筒部を備え、円筒部の外周には、ロック溝が形成され、第１コネクタと第２コネクタとを接続したときには、ロック溝にロック爪が嵌合されるようにした。 The present invention has been made to solve the above-described conventional problems, and as a means for the coaxial connector of the present invention, a first connector including an outer conductor, a center pin or a socket, an outer conductor, A second connector having a socket or a center pin, and connecting the outer conductor of the first connector and the outer conductor of the second connector, and connecting the center pin of the first connector and the socket of the second connector. Alternatively, the socket of the first connector and the center pin of the second connector are connected and used, and the outer conductor of the first connector is provided on the main surface on the side to which the second connector is connected. The first connector and the first connector are provided with a flat portion and a circular opening formed in the flat portion, and the opening is inclined in a direction away from the flat portion as it approaches the central axis of the opening. A tapered portion is formed as a guide for aligning the position when connecting to the connector, a lock claw is formed at the tip of the tapered portion, the outer conductor of the second connector has a cylindrical portion, and the outer periphery of the cylindrical portion is When the first connector and the second connector are connected, a lock claw is fitted into the lock groove.
　第２コネクタの円筒部は、少なくとも１ヶ所に切欠きが設けられて、円筒部の中心軸方向に向かって力を加えると弾性的に変形するものであることが好ましい。この場合には、第１コネクタと第２コネクタとを接続する際に、第２コネクタの円筒部が中心軸方向に向かって弾性的に変形するため、第１コネクタと第２コネクタとをスムースに接続することができる。また、第１コネクタと第２コネクタとを接続した後においては、第１コネクタの外部導体と第２コネクタの外部導体（円筒部）とが弾性的に接触するため、両者の電気的接続が確実になる。なお、弾性的に変形するとは、力を加えると変形するが、力を加えるのを止めると元の形状に戻ることを意味する。 It is preferable that the cylindrical portion of the second connector is provided with a notch at at least one place and is elastically deformed when a force is applied in the direction of the central axis of the cylindrical portion. In this case, when the first connector and the second connector are connected, the cylindrical portion of the second connector is elastically deformed toward the central axis direction, so that the first connector and the second connector are smoothly moved. Can be connected. In addition, after the first connector and the second connector are connected, the outer conductor of the first connector and the outer conductor (cylindrical portion) of the second connector are in elastic contact with each other, so that the electrical connection between them is reliable. become. The term “elastically deformed” means that when a force is applied, the material deforms, but when the force is stopped, the original shape is restored.
　第２コネクタの外部導体が、更に、枠状のはんだ付け部を備え、はんだ付け部と円筒部とが梁によって接続されていることが好ましい。この場合には、円筒部は、はんだ付け部によって支持されているにもかかわらず、中心軸方向に向かって力を加えることによって、弾性的に変形する。すなわち、梁によって、はんだ付け部と円筒部とを接続すれば、円筒部の弾性的な変形は阻害されない。 It is preferable that the outer conductor of the second connector further includes a frame-shaped soldering portion, and the soldering portion and the cylindrical portion are connected by a beam. In this case, the cylindrical portion is elastically deformed by applying a force in the direction of the central axis, despite being supported by the soldering portion. That is, if the soldering portion and the cylindrical portion are connected by the beam, the elastic deformation of the cylindrical portion is not hindered.
　はんだ付け部と円筒部とを接続する梁は、３本であることが好ましい。この場合には、はんだ付け部と円筒部とが強固に接続され、かつ、梁の長さを大きくすることができるため、円筒部の弾性的な変形は更に阻害されなくなる。 It is preferable that there are three beams connecting the soldered portion and the cylindrical portion. In this case, since the soldering portion and the cylindrical portion are firmly connected and the length of the beam can be increased, the elastic deformation of the cylindrical portion is not further hindered.
　第２コネクタが、更に、絶縁体を備え、絶縁体に、第２コネクタのソケットまたはセンターピンがインサートモールドされ、第２コネクタの外部導体が、更に、枠状のはんだ付け部を備え、はんだ付け部に、少なくとも２つの固定用爪が形成され、固定用爪によって、絶縁体が外部導体に固定されたものとすることが好ましい。この場合には、製造工程において、ソケットまたはセンターピンがインサートモールドされた絶縁体を、容易に、外部導体に固定することができる。更に、この場合において、絶縁体に少なくとも２つの固定用凹部が形成され、固定用爪が固定用凹部に固定されていることが好ましい。この場合には、固定用爪を固定用凹部に固定することによって、絶縁体を外部導体に確実に固定することができる。また、固定用爪が固定用凹部に収容されるため、固定用爪の厚みによって第２コネクタの高さ寸法が大きくなってしまうことがない。 The second connector further includes an insulator, the socket or center pin of the second connector is insert-molded in the insulator, the outer conductor of the second connector further includes a frame-shaped soldering portion, and is soldered It is preferable that at least two fixing claws are formed on the portion, and the insulator is fixed to the external conductor by the fixing claws. In this case, in the manufacturing process, the insulator in which the socket or the center pin is insert-molded can be easily fixed to the external conductor. Further, in this case, it is preferable that at least two fixing recesses are formed in the insulator, and the fixing claws are fixed to the fixing recesses. In this case, the insulator can be securely fixed to the external conductor by fixing the fixing claw to the fixing recess. Moreover, since the fixing claw is accommodated in the fixing recess, the height dimension of the second connector does not increase due to the thickness of the fixing claw.
　本発明の同軸コネクタは、ロック爪が、第１コネクタの外部導体の平面部に形成された開口の開口縁部を利用したものであるため、ロック爪を設けているにもかかわらず、第１コネクタの高さ寸法が小さい。すなわち、ロック爪は、従来の同軸コネクタ５００の第２コネクタ５００Ｂのロック爪５８のように、外部導体５５をプレス加工して形成したものではなく、打抜き加工などによって形成された開口の開口縁部を利用したものであるため、ロック爪を設けているにもかかわらず、第１コネクタの高さ寸法は大きくならない。本発明の同軸コネクタは、ロック爪を設けた第１コネクタの高さ寸法が小さいため、第１コネクタと第２コネクタと接続したときの高さ寸法も小さい。 In the coaxial connector according to the present invention, the locking claw uses the opening edge of the opening formed in the flat portion of the outer conductor of the first connector. The height of the connector is small. That is, the lock claw is not formed by pressing the outer conductor 55 like the lock claw 58 of the second connector 500B of the conventional coaxial connector 500, but the opening edge of the opening formed by punching or the like Therefore, the height dimension of the first connector does not increase even though the lock claw is provided. Since the coaxial connector of the present invention has a small height dimension of the first connector provided with the lock claw, the height dimension when the first connector and the second connector are connected is also small.
　また、本発明の同軸コネクタは、第１コネクタの外部導体の平面部に形成された開口にテーパー部を設け、そのテーパー部を、第１コネクタと第２コネクタとを接続する際のガイドとして利用するため、第１コネクタと第２コネクタとの位置合わせが容易である。すなわち、第１コネクタに対して第２コネクタを近づけてゆくと、第１コネクタの中心軸と第２コネクタの中心軸とがずれていても、まず、第２コネクタの円筒部の開口の縁部が第１コネクタの大きな平面部に当接し、続いて、第２コネクタが第１コネクタのテーパー部にガイドされて正しい位置に導かれるため、容易に第１コネクタの中心軸と第２コネクタの中心軸とが合致する。したがって、本発明の同軸コネクタは、第１コネクタと第２コネクタとの位置合わせが容易である。 In the coaxial connector of the present invention, a tapered portion is provided in an opening formed in the flat portion of the outer conductor of the first connector, and the tapered portion is used as a guide when connecting the first connector and the second connector. Therefore, the alignment between the first connector and the second connector is easy. That is, when the second connector is moved closer to the first connector, even if the center axis of the first connector and the center axis of the second connector are shifted, first, the edge of the opening of the cylindrical portion of the second connector Abuts against the large flat surface portion of the first connector, and then the second connector is guided to the correct position by being guided by the tapered portion of the first connector, so that the center axis of the first connector and the center of the second connector can be easily obtained. The axis matches. Therefore, the coaxial connector of the present invention can easily align the first connector and the second connector.

Each of the outer conductor 21 and the socket 22 is made by processing a metal plate such as phosphor bronze, and has a surface plated with Ni, Ag, Au, or the like. The insulator 23 is made of resin. The socket 22 is insert-molded in an insulator (resin) 23. The insulator 23 in which the socket 22 is insert-molded is fixed to the outer conductor 21.
　外部導体２１は、本体部分として、円筒状の円筒部２１ａを備えている。 The outer conductor 21 includes a cylindrical portion 21a as a main body portion.
　円筒部２１ａは、１ヶ所に切欠き２１ｂが設けられている。円筒部２１ａは、切欠き２１ｂが設けられているため、完全な環状にはなっていない。したがって、円筒部２１ａは、円筒部２１ａの中心軸方向に向かって力を加えると、弾性的に変形する。弾性的に変形するとは、上述したとおり、力を加えると変形するが、力を加えるのを止めると元の形状に戻ることを意味する。なお、本実施形態においては、円筒部２１ａの１ヶ所に切欠き２１ｂを設けたが、円筒部２１ａの２ヶ所以上に切欠き２１ｂを設けても良い。 The cylindrical portion 21a is provided with a notch 21b at one location. Since the cylindrical portion 21a is provided with a notch 21b, the cylindrical portion 21a does not have a complete annular shape. Therefore, the cylindrical portion 21a is elastically deformed when a force is applied toward the central axis direction of the cylindrical portion 21a. As described above, elastically deforming means that when a force is applied, the material is deformed, but when the force is stopped, the original shape is restored. In the present embodiment, the notch 21b is provided at one location of the cylindrical portion 21a. However, the notch 21b may be provided at two or more locations of the cylindrical portion 21a.
　円筒部２１ａの外周に、ロック溝２１ｃが形成されている。 A lock groove 21c is formed on the outer periphery of the cylindrical portion 21a.
　また、外部導体２１は、枠状のはんだ付け部２１ｄを備えている。枠状とは、中央部分に空間（非形成部）を有するという意味である。本実施形態においては、はんだ付け部２１ｄは、略Ｃ字状に形成されている。 Further, the outer conductor 21 includes a frame-shaped soldering portion 21d. The frame shape means that there is a space (non-formed part) in the central part. In the present embodiment, the soldering portion 21d is formed in a substantially C shape.
　はんだ付け部２１ｄと円筒部２１ａとが、３本の梁２１ｅによって接続されている。梁２１ｅは、はんだ付け部２１ｄおよび円筒部２１ａと、一体的に形成されている。円筒部２１ａは、はんだ付け部２１ｄによって支持されているにもかかわらず、中心軸方向に向かって力を加えることによって、弾性的に変形する。すなわち、はんだ付け部２１ｄと円筒部２１ａとの接続を、梁２１ｅによっておこなっているため、円筒部２１ａの中心軸方向への弾性的な変形は阻害されていない。しかも、梁２１ｅの個数を３本にしているため、円筒部２１ａとはんだ付け部２１ｄとは、強固に接続されている。 The soldering part 21d and the cylindrical part 21a are connected by three beams 21e. The beam 21e is formed integrally with the soldering portion 21d and the cylindrical portion 21a. Although the cylindrical portion 21a is supported by the soldering portion 21d, the cylindrical portion 21a is elastically deformed by applying a force toward the central axis direction. That is, since the soldering portion 21d and the cylindrical portion 21a are connected by the beam 21e, the elastic deformation in the central axis direction of the cylindrical portion 21a is not hindered. Moreover, since the number of the beams 21e is three, the cylindrical portion 21a and the soldering portion 21d are firmly connected.
　また、外部導体２１のはんだ付け部２１ｄに、内側に向かって突出した、２つの固定用爪２１ｆが設けられている。 Further, two fixing claws 21f protruding inward are provided on the soldering portion 21d of the outer conductor 21.
　ソケット２２は、円筒状の接続部２２ａを備えている。接続部２２ａの１カ所に、ソケット２２の中心軸と平行な方向に、合わせ目２２ｂが形成されている。接続部２２ａの内径は、内部に第１コネクタ１００Ａのセンターピン１２の接続部１２ａを嵌合できる大きさに設定されている。 The socket 22 includes a cylindrical connecting portion 22a. A seam 22b is formed at one location of the connecting portion 22a in a direction parallel to the central axis of the socket 22. The inner diameter of the connecting portion 22a is set to a size that allows the connecting portion 12a of the center pin 12 of the first connector 100A to be fitted therein.
　ソケット２２には、接続部２２ａから平面方向に延びる、はんだ付け部２２ｃが形成されている。 The socket 22 is formed with a soldering portion 22c extending in the plane direction from the connection portion 22a.
　絶縁体２３には、上述したとおり、ソケット２２がインサートモールドされている。絶縁体２３からは、ソケット２２の接続部２２ａとはんだ付け部２２ｃとが、外部に露出されている。また、絶縁体２３には、外部導体２１の固定用爪２１ｆを固定するための、２つの固定用凹部２３ａが形成されている。 As described above, the socket 22 is insert-molded in the insulator 23. From the insulator 23, the connecting portion 22a and the soldering portion 22c of the socket 22 are exposed to the outside. The insulator 23 is formed with two fixing recesses 23 a for fixing the fixing claws 21 f of the outer conductor 21.
　ソケット２２がインサートモールドされた絶縁体２３は、外部導体２１に固定されている。より具体的には、絶縁体２３を、外部導体２１の円筒部２１ａに当接させて、外部導体２１の枠状のはんだ付け部２１ｄの内側に配置し、固定用爪２１ｆを固定用凹部２３ａに固定することによって、絶縁体２３が外部導体２１に固定されている。なお、固定後は、固定用爪２１ｆが固定用凹部２３ａ内に収容されるため、第２コネクタ１００Ｂの高さ寸法が固定用爪２１ｆの厚みによって大きくなってしまうことはない。 The insulator 23 in which the socket 22 is insert-molded is fixed to the outer conductor 21. More specifically, the insulator 23 is placed in contact with the cylindrical portion 21a of the outer conductor 21 and arranged inside the frame-shaped soldering portion 21d of the outer conductor 21, and the fixing claw 21f is fixed to the fixing recess 23a. The insulator 23 is fixed to the outer conductor 21 by fixing to the outer conductor 21. After fixing, the fixing claw 21f is accommodated in the fixing recess 23a, so that the height dimension of the second connector 100B is not increased by the thickness of the fixing claw 21f.
　第２コネクタ１００Ｂは、外部導体２１のはんだ付け部２１ｄ、および、ソケット２２のはんだ付け部２２ｃを、ランド電極などにはんだ付けすることにより、セラミック基板、樹脂基板、可撓性を備えたフレキシブル基板などに実装されて使用される。 The second connector 100B includes a ceramic substrate, a resin substrate, and a flexible substrate having flexibility by soldering the soldering portion 21d of the outer conductor 21 and the soldering portion 22c of the socket 22 to a land electrode or the like. It is implemented and used.
　同軸コネクタ１００の第１コネクタ１００Ａおよび第２コネクタ１００Ｂは、それぞれ、従来から同軸コネクタを製造するのに広く使用されている製造方法によって製造することができる。簡単に説明すると、次のとおりである。 The first connector 100A and the second connector 100B of the coaxial connector 100 can each be manufactured by a manufacturing method that has been widely used for manufacturing a coaxial connector. Briefly described, it is as follows.
　まず、第１コネクタ１００Ａの外部導体１１、センターピン１２、第２コネクタ１００Ｂの外部導体２１、ソケット２２の、それぞれの材料となる、リン青銅などの金属板を用意する。 First, metal plates such as phosphor bronze, which are the respective materials for the outer conductor 11 of the first connector 100A, the center pin 12, the outer conductor 21 of the second connector 100B and the socket 22, are prepared.
　次に、用意した金属板に対して、打抜き加工、プレス加工、曲げ加工、鍛造加工などを、適宜、施して、外部導体１１、センターピン１２、外部導体２１、ソケット２２を作製する。なお、これらの工程は、通常、外部導体１１、センターピン１２、外部導体２１、ソケット２２を、それぞれ、リードフレームに接続した状態でおこなう。 Next, a punching process, a pressing process, a bending process, a forging process, and the like are appropriately performed on the prepared metal plate to produce the outer conductor 11, the center pin 12, the outer conductor 21, and the socket 22. These steps are usually performed in a state where the outer conductor 11, the center pin 12, the outer conductor 21, and the socket 22 are connected to the lead frame.
　次に、外部導体１１、センターピン１２、外部導体２１、ソケット２２の表面に、それぞれ、めっきを施す。 Next, the surfaces of the outer conductor 11, the center pin 12, the outer conductor 21, and the socket 22 are plated.
　次に、金型を用意し、金型の内部にセンターピン１２を収容したうえで、金型の内部に樹脂を注入し、硬化させて、所定の形状からなる絶縁体１３を成型する。同様に、金型の内部にソケット２２を収容したうえで、金型の内部に樹脂を注入し、硬化させて、所定の形状からなる絶縁体２３を成型する。すなわち、絶縁体１３にセンターピン１２をインサートモールドし、絶縁体２３にソケット２２をインサートモールドする。なお、これらの工程は、通常、センターピン１２、ソケット２２を、それぞれ、リードフレームに接続した状態でおこない、絶縁体１３や絶縁体２３を成型した後に、不要なリードフレームを切断する。 Next, a mold is prepared, and after the center pin 12 is accommodated in the mold, a resin is injected into the mold and cured to mold the insulator 13 having a predetermined shape. Similarly, after housing the socket 22 in the mold, a resin is injected into the mold and cured to mold the insulator 23 having a predetermined shape. That is, the center pin 12 is insert-molded in the insulator 13, and the socket 22 is insert-molded in the insulator 23. These steps are usually performed with the center pin 12 and the socket 22 connected to the lead frame, respectively, and after the insulator 13 and the insulator 23 are molded, unnecessary lead frames are cut.
　次に、センターピン１２がインサートモールドされた絶縁体１３を、外部導体１１に固定する。具体的には、外部導体１１のはんだ付け部１１ｅの先端を折り曲げ、はんだ付け部１１ｅの先端を固定用凹部１３ａに加締めることによって、絶縁体１３を外部導体１１に固定する。 Next, the insulator 13 in which the center pin 12 is insert-molded is fixed to the outer conductor 11. Specifically, the insulator 13 is fixed to the external conductor 11 by bending the tip of the soldering portion 11e of the outer conductor 11 and crimping the tip of the soldering portion 11e to the fixing recess 13a.
　同様に、ソケット２２がインサートモールドされた絶縁体２３を、外部導体２１に固定する。具体的には、まず、図７（Ａ）に示すように、絶縁体２３を、外部導体２１の円筒部２１ａに当接させて、外部導体２１の枠状のはんだ付け部２１ｄの内側に配置する。次に、図７（Ｂ）に示すように、外部導体２１のはんだ付け部２１ｄを、両側から一点鎖線矢印Ｘ方向に変形させて、固定用爪２１ｆを固定用凹部２３ａに加締める。この結果、図７（Ｃ）に示すように、絶縁体２３が外部導体２１に固定される。 Similarly, the insulator 23 in which the socket 22 is insert-molded is fixed to the outer conductor 21. Specifically, first, as shown in FIG. 7A, the insulator 23 is placed in contact with the cylindrical portion 21a of the outer conductor 21 and inside the frame-shaped soldering portion 21d of the outer conductor 21. To do. Next, as shown in FIG. 7B, the soldering portion 21d of the outer conductor 21 is deformed from both sides in the direction of the dashed-dotted arrow X, and the fixing claw 21f is crimped to the fixing recess 23a. As a result, the insulator 23 is fixed to the outer conductor 21 as shown in FIG.
　以上により、第１コネクタ１００Ａおよび第２コネクタ１００Ｂが完成する。 Thus, the first connector 100A and the second connector 100B are completed.
　次に、第１コネクタ１００Ａと第２コネクタ１００Ｂとの接続方法について説明する。 Next, a method for connecting the first connector 100A and the second connector 100B will be described.
　まず、図８（Ａ）に示すように、第１コネクタ１００Ａの中心軸と第２コネクタ１００Ｂの中心軸とを揃えて、第１コネクタ１００Ａのセンターピン１２が形成された側と第２コネクタ１００Ｂのソケット２２が形成された側とを対向させて、第１コネクタ１００Ａと第２コネクタ１００Ｂとを配置する。なお、このとき、第１コネクタ１００Ａと第２コネクタ１００Ｂとは、それぞれ、既に基板などに実装されている。 First, as shown in FIG. 8A, the center axis of the first connector 100A and the center axis of the second connector 100B are aligned, and the side where the center pin 12 of the first connector 100A is formed and the second connector 100B. The first connector 100A and the second connector 100B are arranged facing the side on which the socket 22 is formed. At this time, the first connector 100A and the second connector 100B are already mounted on a substrate or the like.
　次に、同じく図８（Ａ）に矢印で示すように、第１コネクタ１００Ａに対して、第２コネクタ１００Ｂを接近させてゆく。 Next, as indicated by an arrow in FIG. 8A, the second connector 100B is moved closer to the first connector 100A.
　このとき、第１コネクタ１００Ａの中心軸と第２コネクタ１００Ｂの中心軸とが合致していると、第１コネクタ１００Ａの外部導体１１の開口１１ｂに、第２コネクタ１００Ｂの外部導体２１の円筒部２１ａの先端が挿入されるとともに、第２コネクタ１００Ｂのソケット２２の接続部２２ａに、第１コネクタ１００Ａのセンターピン１２の接続部１２ａの先端が挿入される。 At this time, if the central axis of the first connector 100A coincides with the central axis of the second connector 100B, the cylindrical portion of the outer conductor 21 of the second connector 100B is formed in the opening 11b of the outer conductor 11 of the first connector 100A. The tip of 21a is inserted, and the tip of connection portion 12a of center pin 12 of first connector 100A is inserted into connection portion 22a of socket 22 of second connector 100B.
　一方、第１コネクタ１００Ａの中心軸と第２コネクタ１００Ｂの中心軸とがずれていると、まず、第２コネクタ１００Ｂの外部導体２１の円筒部２１ａの開口の縁部が、第１コネクタ１００Ａの外部導体１１のテーパー部１１ｃ（あるいは平面部１１ａ）に当接する。そして、更に、第２コネクタ１００Ｂを第１コネクタ１００Ａに対して接近させてゆくと、円筒部２１ａがテーパー部１１ｃに導かれ、第２コネクタ１００Ｂが正しい位置にシフトし、第１コネクタ１００Ａの中心軸と第２コネクタ１００Ｂの中心軸とが合致する。そして、第１コネクタ１００Ａの中心軸と第２コネクタ１００Ｂの中心軸とが合致したうえで、第１コネクタ１００Ａの外部導体１１の開口１１ｂに、第２コネクタ１００Ｂの外部導体２１の円筒部２１ａの先端が挿入されるとともに、第２コネクタ１００Ｂのソケット２２の接続部２２ａに、第１コネクタ１００Ａのセンターピン１２の接続部１２ａの先端が挿入される。すなわち、テーパー部１１ｃが、第１コネクタ１００Ａと第２コネクタ１００Ｂとを接続する際の、位置を合せのためのガイドとして働く。 On the other hand, if the center axis of the first connector 100A and the center axis of the second connector 100B are deviated, first, the edge of the opening of the cylindrical portion 21a of the outer conductor 21 of the second connector 100B is the first connector 100A. It contacts the tapered portion 11c (or the flat surface portion 11a) of the outer conductor 11. When the second connector 100B is further moved closer to the first connector 100A, the cylindrical portion 21a is guided to the tapered portion 11c, and the second connector 100B is shifted to the correct position, so that the center of the first connector 100A is reached. The axis matches the central axis of the second connector 100B. Then, after the center axis of the first connector 100A and the center axis of the second connector 100B are matched, the opening 11b of the outer conductor 11 of the first connector 100A is inserted into the cylindrical portion 21a of the outer conductor 21 of the second connector 100B. The tip is inserted, and the tip of the connecting portion 12a of the center pin 12 of the first connector 100A is inserted into the connecting portion 22a of the socket 22 of the second connector 100B. That is, the taper portion 11c serves as a guide for aligning the positions when connecting the first connector 100A and the second connector 100B.
　そして、更に、第２コネクタ１００Ｂを第１コネクタ１００Ａに対して接近させてゆくと、第１コネクタ１００Ａの外部導体１１の開口１１ｂの開口縁部に押されて、第２コネクタ１００Ｂの外部導体２１の円筒部２１ａが、円筒部２１ａの中心軸方向に向かって弾性的に変形する。 When the second connector 100B is further brought closer to the first connector 100A, it is pushed by the opening edge of the opening 11b of the outer conductor 11 of the first connector 100A, and the outer conductor 21 of the second connector 100B. The cylindrical portion 21a is elastically deformed toward the central axis direction of the cylindrical portion 21a.
　続いて、更に、第２コネクタ１００Ｂを第１コネクタ１００Ａに対して接近させてゆくと、図８（Ｂ）に示すように、第２コネクタ１００Ｂの外部導体２１のロック溝２１ｃに第１コネクタ１００Ａの外部導体１１のロック爪１１ｄが嵌合されるとともに、外部導体１１と外部導体２１とが接続され、かつ、センターピン１２とソケット２２とが接続されて、第１コネクタ１００Ａと第２コネクタ１００Ｂとの接続が完了する。 Subsequently, when the second connector 100B is further brought closer to the first connector 100A, as shown in FIG. 8B, the first connector 100A is inserted into the lock groove 21c of the outer conductor 21 of the second connector 100B. The lock claw 11d of the external conductor 11 is fitted, the external conductor 11 and the external conductor 21 are connected, the center pin 12 and the socket 22 are connected, and the first connector 100A and the second connector 100B. Connection with is completed.
　なお、同軸コネクタ１００は、第１コネクタ１００Ａから離れる方向に、第２コネクタ１００Ｂを引っ張ることにより、ロック溝２１ｃとロック爪１１ｄとの嵌合が外れて、第１コネクタ１００Ａと第２コネクタ１００Ｂとの接続が解除される。 The coaxial connector 100 pulls the second connector 100B in the direction away from the first connector 100A, so that the fitting between the lock groove 21c and the lock claw 11d is released, and the first connector 100A and the second connector 100B Is disconnected.
　以上説明した、実施形態にかかる同軸コネクタ１００は、次のような特長を備えている。 The coaxial connector 100 according to the embodiment described above has the following features.
　本発明の同軸コネクタ１００は、ロック爪１１ｄが、第１コネクタ１００ａの外部導体１１の平面部１１ａに形成された開口１１ｂの開口縁部を利用したものであるため、ロック爪１１ｄを設けているにもかかわらず、第１コネクタ１００Ａは高さ寸法が小さい。すなわち、ロック爪１１ｄは、従来の同軸コネクタ５００の第２コネクタ５００Ｂのロック爪５８のように、外部導体５５をプレス加工して形成したものではなく、打抜き加工などによって形成された開口の開口縁部を利用したものであるため、ロック爪１１ｄを設けているにもかかわらず、第１コネクタ１００Ａの高さ寸法は小さい。そして、同軸コネクタ１００は、ロック爪１１ｄを設けた第１コネクタ１００Ａの高さ寸法が小さいため、第１コネクタ１００Ａと第２コネクタ１００Ｂとを接続したときの高さ寸法も小さい。 In the coaxial connector 100 of the present invention, the lock claw 11d is provided with the lock claw 11d because the lock claw 11d uses the opening edge of the opening 11b formed in the flat portion 11a of the outer conductor 11 of the first connector 100a. Nevertheless, the first connector 100A has a small height dimension. That is, the lock claw 11d is not formed by pressing the outer conductor 55 like the lock claw 58 of the second connector 500B of the conventional coaxial connector 500, but the opening edge of the opening formed by punching or the like. The height dimension of the first connector 100A is small even though the lock claw 11d is provided. Since the coaxial connector 100 has a small height dimension of the first connector 100A provided with the lock claw 11d, the height dimension when the first connector 100A and the second connector 100B are connected is also small.
　同軸コネクタ１００は、第１コネクタ１００Ａの外部導体１１の平面部１１ａに形成された開口１１ｂにテーパー部１１ｃを設け、そのテーパー部１１ｃを、第１コネクタ１００Ａと第２コネクタ１００Ｂとを接続する際のガイドとして利用するため、第１コネクタ１００Ａと第２コネクタ１００Ｂとの位置合わせが容易である。 In the coaxial connector 100, a tapered portion 11c is provided in an opening 11b formed in the flat surface portion 11a of the outer conductor 11 of the first connector 100A, and the tapered portion 11c is connected to the first connector 100A and the second connector 100B. Therefore, it is easy to align the first connector 100A and the second connector 100B.
　同軸コネクタ１００は、第２コネクタ１００Ｂの円筒部２１ａが、少なくとも１ヶ所に切欠き２１ｂが設けられたものであり、円筒部２１ａの中心軸方向に向かって力を加えると弾性的に変形するものであるため、第１コネクタ１００Ａと第２コネクタ１００Ｂとを接続する際には、円筒部２１ａが中心軸方向に向かって弾性的に変形し、第１コネクタ１００Ａと第２コネクタ１００Ｂとをスムースに接続することができる。また、第１コネクタ１００Ａと第２コネクタ１００Ｂとを接続した後においては、第１コネクタ１００Ａの外部導体１１と第２コネクタ１００Ｂの外部導体２１（円筒部２１ａ）とが弾性的に接触するため、両者の電気的接続が確実になっている。 In the coaxial connector 100, the cylindrical portion 21a of the second connector 100B is provided with at least one notch 21b, and is elastically deformed when a force is applied toward the central axis of the cylindrical portion 21a. Therefore, when connecting the first connector 100A and the second connector 100B, the cylindrical portion 21a is elastically deformed toward the central axis direction, and the first connector 100A and the second connector 100B are smoothly moved. Can be connected. In addition, after connecting the first connector 100A and the second connector 100B, the outer conductor 11 of the first connector 100A and the outer conductor 21 (cylindrical portion 21a) of the second connector 100B are elastically contacted, The electrical connection between the two is ensured.
　同軸コネクタ１００は、第２コネクタ１００Ｂの外部導体２１において、円筒部２１ａとはんだ付け部２１ｄとが梁２１ｅによって接続されているため、円筒部２１ａが、はんだ付け部２１ｄによって支持されているにもかかわらず、中心軸方向に向かって力を加えることによって、良好に弾性的に変形する。また、円筒部２１ａとはんだ付け部２１ｄとが３本の梁２１ｅによって接続されているため、円筒部２１ａとはんだ付け部２１ｄとが強固に接続されている。また、梁２１ｅの個数が３本であるため、それぞれの梁２１ｅの長さを大きくできており、このことも円筒部２１ａの良好な弾性的な変形を妨げない要因になっている。 In the coaxial connector 100, since the cylindrical portion 21a and the soldering portion 21d are connected by the beam 21e in the outer conductor 21 of the second connector 100B, the cylindrical portion 21a is supported by the soldering portion 21d. Regardless, by applying a force in the direction of the central axis, it deforms elastically well. Moreover, since the cylindrical part 21a and the soldering part 21d are connected by the three beams 21e, the cylindrical part 21a and the soldering part 21d are firmly connected. Further, since the number of the beams 21e is three, the length of each beam 21e can be increased, and this is also a factor that does not hinder good elastic deformation of the cylindrical portion 21a.
　同軸コネクタ１００は、第１コネクタ１００Ａにおいて、絶縁体１３を外部導体１１に固定するにあたり、折り曲げたはんだ付け部１２ｂの先端を固定用凹部１３ａ内に収容しているため、第１コネクタ１００Ａの高さ寸法がはんだ付け部１２ｂの厚みによって大きくなっていない。同様に、第２コネクタ１００Ｂにおいて、絶縁体２３を外部導体２１に固定するにあたり、固定用爪２１ｆを固定用凹部２３ａ内に収容しているため、第２コネクタ２００Ｂの高さ寸法が固定用爪２１ｆの厚みによって大きくなっていない。 In the first connector 100A, the coaxial connector 100 accommodates the tip of the bent soldering portion 12b in the fixing recess 13a when fixing the insulator 13 to the outer conductor 11, so that the height of the first connector 100A is increased. The size is not increased by the thickness of the soldering portion 12b. Similarly, in fixing the insulator 23 to the outer conductor 21 in the second connector 100B, since the fixing claw 21f is accommodated in the fixing recess 23a, the height dimension of the second connector 200B is fixed to the fixing claw. It is not increased by the thickness of 21f.
　以上、実施形態にかかる同軸コネクタ１００について説明した。しかしながら、本発明が上述した内容に限定されることはなく、発明の趣旨に沿って、種々の変更を加えることができる。 The coaxial connector 100 according to the embodiment has been described above. However, the present invention is not limited to the contents described above, and various modifications can be made in accordance with the spirit of the invention.
　たとえば、同軸コネクタ１００では、第１コネクタ１００Ａにセンターピン１２を形成し、第２コネクタ１００Ｂにソケット２２を形成したが、これを入れ替えて、第１コネクタ１００Ａにソケット２２を形成し、第２コネクタ１００Ｂにセンターピン１２を形成しても良い。 For example, in the coaxial connector 100, the center pin 12 is formed on the first connector 100A and the socket 22 is formed on the second connector 100B. However, this is replaced, and the socket 22 is formed on the first connector 100A. The center pin 12 may be formed on 100B.
