Abstract

<P>PROBLEM TO BE SOLVED: To provide a coaxial plug capable of easily processing a screwing work with a receptacle, connecting with both a screw receptacle and a non-screw receptacle, and preventing its coming-off from the receptacle. <P>SOLUTION: The coaxial plug is equipped with a contact pin 7 arranged at a center of a cylindrical member, a separating piece 11 with a tip of the cylindrical member separated into a plurality of parts each having elasticity, and a female screw part 9 for screwing with a tip part 10a of a male screw of a receptacle 41. Also equipped is a ring 19, surrounding a periphery of the separating piece separated into a plurality of parts. Since the female screw part 9 of the cylindrical member is joined to the male screw part 10a of the receptacle 41 in a screwed condition, the coaxial cable will not fall off from the receptacle 41, even if the coaxial cable is pulled by a strong external force. Furthermore, the number of screw threads of the female screw part 9 of the cylindrical member 3 is fewer, and the female screw part 9 is screwed only to the male screw part tip 10a of the receptacle side, so that screwing work becomes facilitated. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は、同軸ケーブルの先端に取り付けられ、リセプタクルと結合される同軸プラグに関する。   The present invention relates to a coaxial plug that is attached to a distal end of a coaxial cable and is coupled to a receptacle.

この種のプラグとしては、例えば、特許文献1に示すように、円筒部材の中心にコンタクトピンを配置してなるものが知られている。この同軸プラグは、いわゆるプッシュオン結合方式によるもので、リセプタクルと結合する際、コンタクトピンをリセプタクルの雄ネジ部の中心孔に挿入し、円筒部材をリセプタクルの雄ネジ部に嵌合させている。
特開2000‐299173号
As this type of plug, for example, as shown in Patent Document 1, a plug in which a contact pin is arranged at the center of a cylindrical member is known. This coaxial plug is based on a so-called push-on coupling system, and when coupled with a receptacle, a contact pin is inserted into the center hole of the male thread portion of the receptacle, and a cylindrical member is fitted into the male thread portion of the receptacle.
JP 2000-299173 A

この同軸プラグ1は、リセプタクルとの結合が容易であるため、例えば、アンテナコンセント40に設けられ、テレビのアンテナ端子に接続されているリセプタクル41に接続される。しかし、同軸プラグ1は、円筒部材3をリセプタクルの雄ネジ部に嵌め込んであるだけなので、同軸ケーブルが引っ張られると、リセプタクルから抜け易いという欠点がある。   Since the coaxial plug 1 can be easily coupled to the receptacle, the coaxial plug 1 is connected to a receptacle 41 provided in an antenna outlet 40 and connected to an antenna terminal of a television, for example. However, the coaxial plug 1 only has the cylindrical member 3 fitted into the male thread portion of the receptacle, and therefore has a drawback that it is easy to come out of the receptacle when the coaxial cable is pulled.

また、図8に示すように、従来のアンテナコンセント40に取り付けられるリセプタクルとしては、外周部がネジを有するネジタイプリセプタクル41aと外周部にネジを有しないネジなしタイプリセプタクル41bとに分かれる。従来の同軸プラグにおけるネジタイプ同軸プラグは参照番号1bに示すように構成される。なお、このネジタイプ同軸プラグ1bは、A−A線で切断された下部を理解が容易なように端面図で表示してある。このようなネジタイプ同軸プラグ1bを、ネジタイプリセプタクル41aと接続する場合には2点鎖線Dで示すように、円筒部材3の内部の雌ねじ28をリセプタクル41aの雄ねじ10bに螺合させることによってネジタイプ同軸プラグ1bとネジタイプリセプタクル41aとを接続できる。ただし、この場合には、円筒部材3の内部の雌ねじ28をネジタイプリセプタクル41aの雄ねじ10bと完全に結合できるまで回転させる必要がある。   As shown in FIG. 8, the receptacle attached to the conventional antenna outlet 40 is divided into a screw type receptacle 41a having an outer peripheral portion having a screw and a screwless type receptacle 41b having no outer peripheral portion. The screw type coaxial plug in the conventional coaxial plug is configured as indicated by reference numeral 1b. The screw type coaxial plug 1b is shown in an end view so that the lower part cut along the line AA is easy to understand. When such a screw-type coaxial plug 1b is connected to the screw-type receptacle 41a, as shown by a two-dot chain line D, the female screw 28 inside the cylindrical member 3 is screwed into the male screw 10b of the receptacle 41a. The type coaxial plug 1b and the screw type receptacle 41a can be connected. However, in this case, it is necessary to rotate the internal thread 28 inside the cylindrical member 3 until it can be completely coupled with the external thread 10b of the screw type receptacle 41a.

一方、このようなネジタイプ同軸プラグ1bを、ネジなしタイプリセプタクル41bと接続する場合には、2点鎖線Cで示すように、円筒部材3の内部の雌ねじ28をネジなしタイプリセプタクル41bの外周部10cに押し込むことによって行うが、通常は雌ねじ28の内周がネジなしタイプリセプタクル41bの外周部10cよりも小さいので接続は不可能である。   On the other hand, when such a screw type coaxial plug 1b is connected to the screwless type receptacle 41b, as shown by a two-dot chain line C, the female screw 28 inside the cylindrical member 3 is connected to the outer peripheral portion of the screwless type receptacle 41b. However, since the inner periphery of the female screw 28 is usually smaller than the outer periphery 10c of the screwless type receptacle 41b, connection is impossible.

本発明は、このような事情に鑑み、ネジタイプリセプタクルまたはネジなしタイプリセプタクルに係わらず接続でき、かつ同軸プラグがリセプタクルからの抜け落ちを防止できる同軸プラグを提供することを目的とする。   In view of such circumstances, an object of the present invention is to provide a coaxial plug that can be connected regardless of a screw type receptacle or a screwless type receptacle, and in which the coaxial plug can be prevented from falling off from the receptacle.

上記課題を解決するために、第1の発明は、円筒部材の中心に配置されたコンタクトピンと、円筒部材の先端が複数の部分に分割され各部分が弾性を有する分割片と、上記円筒部材の内面にリセプタクルの雄ネジの先端部と螺合する雌ネジ部と備えたことを特徴とする。   In order to solve the above-described problems, a first invention includes a contact pin disposed at the center of a cylindrical member, a split piece in which the tip of the cylindrical member is divided into a plurality of portions, each portion having elasticity, An internal thread portion is provided on the inner surface of the internal thread portion so as to be screwed with the distal end portion of the male thread of the receptacle.

また、第3の発明は、同軸接続部を有するL型同軸プラグにおいて、前記同軸接続部は、円筒部材の中心に配置されたコンタクトピンと、円筒部材の先端が複数の部分に分割され各部分が弾性を有する分割片と、上記円筒部材の内面にリセプタクルの雄ネジの先端部と螺合する雌ネジ部とを備えたたことを特徴とする。   According to a third aspect of the present invention, in the L-type coaxial plug having a coaxial connection portion, the coaxial connection portion includes a contact pin disposed at the center of the cylindrical member and a tip of the cylindrical member divided into a plurality of portions. It is characterized in that an elastic divided piece and an internal thread portion which is screwed with a front end portion of an external thread of the receptacle are provided on the inner surface of the cylindrical member.

また、第4の発明は、ケースのいずれかの面に同軸接続部を有するT型分配器において、前記同軸接続部は、円筒部材の中心に配置されたコンタクトピンと、円筒部材の先端が複数の部分に分割され各部分が弾性を有する分割片と、上記円筒部材の内面にリセプタクルの雄ネジの先端部と螺合する雌ネジ部とを備えたたことを特徴とする。   According to a fourth aspect of the present invention, there is provided a T-type distributor having a coaxial connection portion on any surface of the case, wherein the coaxial connection portion includes a contact pin disposed at the center of the cylindrical member and a plurality of tips of the cylindrical member. It is characterized in that a split piece divided into portions and each portion having elasticity, and a female screw portion to be screwed with a front end portion of a male screw of the receptacle are provided on the inner surface of the cylindrical member.

また、第5の発明は、前記第4の発明における同軸接続部の外周面が、前記ケースの一つの面と同一面またはケースの一つの面よりも外部にはみ出すように配置されていることを特徴とする。   Further, the fifth invention is arranged such that the outer peripheral surface of the coaxial connecting portion in the fourth invention is arranged so as to protrude outside the same surface as one surface of the case or one surface of the case. Features.

第1の発明によれば、円筒部材の雌ネジ部がリセプタクルの雄ネジ部に螺合した状態で結合されるので、同軸ケーブルが外力で強く引っ張られても、同軸ケーブルはリセプタクルから抜け落ちなくなる。また、円筒部材の雌ネジ部のネジ山数が少なく、かつ前記雌ネジ部がリセプタクル側の雄ネジの先端部のみと螺合されるので、螺合作業が容易である。また、第1の発明は、相手のリセプタクルがネジタイプまたはネジなしタイプに係わらず用いることができる。   According to the first aspect of the invention, since the female screw portion of the cylindrical member is coupled in a state of being screwed to the male screw portion of the receptacle, the coaxial cable does not fall out of the receptacle even when the coaxial cable is strongly pulled by an external force. In addition, since the female screw portion of the cylindrical member has a small number of threads and the female screw portion is screwed only with the tip of the male screw on the receptacle side, the screwing operation is easy.

また、第2の発明によれば、上記の複数に分割された分割片の周囲を囲むリングを備えるので、このリングによって上記の分割片が外側に広がることを阻止でき、同軸プラグの抜け落ちを防止できる。   In addition, according to the second aspect of the invention, since the ring surrounding the periphery of the plurality of divided pieces is provided, the divided pieces can be prevented from spreading outward by the ring, and the coaxial plug is prevented from falling off. it can.

また、第3および第4の発明においても、円筒部材の雌ネジ部がリセプタクルの雄ネジ部に螺合した状態で結合されるので、同軸ケーブルが外力で強く引っ張られても、同軸ケーブルはリセプタクルから抜け落ちなくなる。また、円筒部材の雌ネジ部のネジ山数が少なく、かつ前記雌ネジ部がリセプタクル側の雄ネジの先端部のみと螺合されるので、螺合作業が容易である。さらに、第3および第4の発明も、相手のリセプタクルがネジタイプまたはネジなしタイプに係わらず用いることができる。   Also in the third and fourth inventions, since the female screw portion of the cylindrical member is coupled in a state of being screwed to the male screw portion of the receptacle, the coaxial cable remains in the receptacle even when the coaxial cable is strongly pulled by an external force. It will not fall out of. In addition, since the female screw portion of the cylindrical member has a small number of threads and the female screw portion is screwed only with the tip of the male screw on the receptacle side, the screwing operation is easy. Furthermore, the third and fourth inventions can be used regardless of whether the mating receptacle is a screw type or a screwless type.

また、第5の発明によれば、同軸接続部の外周面が、ケースの一つの面よりも外部にはみ出しているので、ケースの同軸接続部を相手のリセプタクルに挿入したままで、セレーションを簡単に回転できるので、螺合作業が容易になる。   Further, according to the fifth invention, since the outer peripheral surface of the coaxial connection portion protrudes outside the one surface of the case, the serration can be easily performed while the coaxial connection portion of the case is inserted into the mating receptacle. Therefore, the screwing operation becomes easy.

実施形態1
以下、本発明の実施形態1の同軸プラグを添付図面に基づいて詳細に説明する。
Embodiment 1
Hereinafter, a coaxial plug according to Embodiment 1 of the present invention will be described in detail with reference to the accompanying drawings.

図1は、本発明の同軸プラグ1が、アンテナコンセント40に設けられたリセプタクル41に結合される様子を示す図である。この同軸プラグ1は、把持部4、セレーション13、円筒部材3、コンタクトピン7、分割片11、リング19から構成される。リセプタクルは、雄ネジ部10aおよび中心孔10bから構成される。この同軸プラグ1は、例えば図1に示すように、結合にあたっては、同軸プラグ1の分割片11をリセプタクル41の雄ネジ部10aの先端に係合させた後、分割片11をリセプタクル41側に押し込む。   FIG. 1 is a view showing a state in which the coaxial plug 1 of the present invention is coupled to a receptacle 41 provided in an antenna outlet 40. The coaxial plug 1 includes a grip portion 4, a serration 13, a cylindrical member 3, a contact pin 7, a split piece 11, and a ring 19. The receptacle includes a male screw portion 10a and a center hole 10b. For example, as shown in FIG. 1, the coaxial plug 1 is coupled with the split piece 11 of the coaxial plug 1 engaged with the tip of the male screw portion 10 a of the receptacle 41, and then the split piece 11 is moved to the receptacle 41 side. Push in.

この押し込みによって、コンタクトピン7がリセプタクル41の中心孔10bに挿入される。このときに、分割片11は、雄ネジ部10aの外周によって弾性変形させられ、雄ネジ部10aの外部を覆うように進入する。分割片11を雄ネジ部10aに挿入した後に、セレーション13を2−3回回転させて図2で示す雌ネジ部9をリセプタクル41の雄ネジ部10aに螺合させる。   By this pushing, the contact pin 7 is inserted into the center hole 10 b of the receptacle 41. At this time, the split piece 11 is elastically deformed by the outer periphery of the male screw portion 10a and enters so as to cover the outside of the male screw portion 10a. After inserting the split piece 11 into the male screw portion 10a, the serration 13 is rotated 2-3 times to screw the female screw portion 9 shown in FIG. 2 into the male screw portion 10a of the receptacle 41.

このように同軸プラグ1の分割片11がリセプタクル41の雄ネジ部10aに螺合した状態で、同軸プラグ1とリセプタクル41とが結合されるので、同軸ケーブル8が外力で引っ張られても、同軸プラグ1がリセプタクル41から抜けることはない。さらに、同軸プラグ1の雌ネジ部9をリセプタクル41側の雄ネジ部10aの先端部にのみ螺合させているので、円筒部材3を2〜3回回転させるだけで同軸プラグ1の雌ネジ部9とリセプタクル41の雄ネジ部10aとの結合が可能である。   In this way, the coaxial plug 1 and the receptacle 41 are coupled with the split piece 11 of the coaxial plug 1 screwed into the male threaded portion 10a of the receptacle 41. Therefore, even if the coaxial cable 8 is pulled by an external force, The plug 1 does not come out of the receptacle 41. Furthermore, since the female screw portion 9 of the coaxial plug 1 is screwed only with the tip portion of the male screw portion 10a on the receptacle 41 side, the female screw portion of the coaxial plug 1 can be obtained simply by rotating the cylindrical member 3 two or three times. 9 and the male screw portion 10a of the receptacle 41 can be coupled.

図2は本発明の同軸プラグの詳細断面を示す図である。この同軸プラグ1はいわゆるプッシュオン結合方式と呼ばれるものであり、把持部4と円筒部材3からなり、円筒部材3の先端部は複数の分割片11に分割され、各分割片11は弾性材料で構成される。また、把持部4は、同軸ケーブル8とコンタクトピン7とを接続する接続部2を覆い、コンタクトピン7と同軸ケーブル8が外れないように保護する部分である。   FIG. 2 is a view showing a detailed cross section of the coaxial plug of the present invention. The coaxial plug 1 is a so-called push-on coupling method, and includes a grip portion 4 and a cylindrical member 3, and the tip of the cylindrical member 3 is divided into a plurality of divided pieces 11, and each divided piece 11 is made of an elastic material. Composed. The gripping portion 4 is a portion that covers the connection portion 2 that connects the coaxial cable 8 and the contact pin 7 and protects the contact pin 7 and the coaxial cable 8 from being detached.

上記の接続部2は、絶縁体5、圧入内環14、圧入外環15、芯線挿入部16から構成される。圧入内環14に圧入外環15を圧入することによって、圧入内環14と圧入外環15は、きつく結合され、接続部2がフランジ部3aから外れなくなる。圧入内環14と圧入外環15の結合部には周回溝6が形成され、この周回溝6に円筒部材3のフランジ部3aを係合せることによって、円筒部材3は接続部2に対して回転自在となる。   The connection portion 2 includes an insulator 5, a press-fit inner ring 14, a press-fit outer ring 15, and a core wire insertion portion 16. By press-fitting the press-fit outer ring 15 into the press-fit inner ring 14, the press-fit inner ring 14 and the press-fit outer ring 15 are tightly coupled, and the connecting portion 2 does not come off from the flange portion 3a. A circumferential groove 6 is formed at the joint between the press-fitted inner ring 14 and the press-fitted outer ring 15, and the cylindrical member 3 rotates with respect to the connection part 2 by engaging the flange part 3 a of the cylindrical member 3 with the circumferential groove 6. Be free.

絶縁体5にはコンタクトピン7が挿入される。このコンタクトピン7は、その端で芯線挿入部16と結合されている。この芯線挿入部16に同軸ケーブル8の芯線17を挿入することによって、コンタクトピン7と芯線17とが電気的に接続される。一方、円筒部材3は圧入内環14を介して同軸ケーブル8の外部接地導体(図示せず)と接続される。円筒部材3と接続部の結合は種々の構成の結合形式があり、既に公知の技術であるので詳細な説明は省略する。   Contact pins 7 are inserted into the insulator 5. The contact pin 7 is coupled to the core wire insertion portion 16 at its end. By inserting the core wire 17 of the coaxial cable 8 into the core wire insertion portion 16, the contact pin 7 and the core wire 17 are electrically connected. On the other hand, the cylindrical member 3 is connected to an external ground conductor (not shown) of the coaxial cable 8 via the press-fit inner ring 14. Since the cylindrical member 3 and the connecting portion are combined in various configurations and are already known techniques, a detailed description thereof will be omitted.

円筒部材3の内面には雌ネジ部9が形成される。この雌ネジ部9は、図2に示すリセプタクル41の雄ネジ部10aの先端部と螺合する位置に配置されるとともに、雄ネジ部10aの先端部との間で2−3回の回転によって螺合するようなネジ山数に形成される。雌ネジ部9から先端を見た方向は、複数の分割片に分割され、各分割片11間には間隙11aが形成され、各分割片は弾性を有している。この分割片11が、雄ネジ部10aを挟持し、円筒部材3とリセプタクル41とを結合させる。分割片11の先端部12は傾斜部3bを有し、この傾斜部3bは、分割片11が雄ネジ部10aに挿入され易くなる役目を有する。   A female screw portion 9 is formed on the inner surface of the cylindrical member 3. The female screw portion 9 is disposed at a position where the female screw portion 10a of the receptacle 41 shown in FIG. 2 is screwed together, and is rotated 2-3 times between the male screw portion 10a and the front end portion. The number of threads is such that it can be screwed together. The direction in which the tip is viewed from the female screw portion 9 is divided into a plurality of divided pieces, a gap 11a is formed between the divided pieces 11, and each divided piece has elasticity. The divided piece 11 sandwiches the male screw portion 10 a and connects the cylindrical member 3 and the receptacle 41. The distal end portion 12 of the divided piece 11 has an inclined portion 3b, and this inclined portion 3b has a role that makes it easy for the divided piece 11 to be inserted into the male screw portion 10a.

図3は、分割片11の部分を詳細に示している同軸プラグ1の一部断面図である。図3に示すように、分割片11は、リセプタクル41の雄ネジ部10aを挟持すべく雌ネジ部9から先端部12に向って周方向に等間隔で複数個配置される。また、分割片11の外面には、分割片11を雄ネジ部10aに挿入したときに、分割片11が外側に開きすぎることを防止するリング19が設けられる。また、先端部の反対側には、円筒部材3と一体化されたセレーション13が形成され、このセレーション13を回転させることによって、円筒部材3が回転し、雌ネジ部9と雄ネジ部10aとが螺合される。   FIG. 3 is a partial cross-sectional view of the coaxial plug 1 showing a part of the segment piece 11 in detail. As shown in FIG. 3, a plurality of divided pieces 11 are arranged at equal intervals in the circumferential direction from the female screw portion 9 toward the distal end portion 12 so as to sandwich the male screw portion 10 a of the receptacle 41. In addition, a ring 19 is provided on the outer surface of the split piece 11 to prevent the split piece 11 from opening too far outward when the split piece 11 is inserted into the male screw portion 10a. Further, a serration 13 integrated with the cylindrical member 3 is formed on the opposite side of the tip portion. By rotating the serration 13, the cylindrical member 3 is rotated, and the female screw portion 9 and the male screw portion 10a. Are screwed together.

また、分割片11がリセプタクル41の雄ネジ部10aを挟持する構造になっているので、雌ネジ部9と雄ネジ部10aとの螺合を忘れてしまっても、従来のものと同等の結合強度を維持できる。
実施形態2
また、本発明は、上述のように、同軸プラグ1のコンタクトピン7が同軸ケーブル8と一直線に構成される同軸プラグ1に限定されるものではなく、例えば、図4に示すような同軸プラグ1のコンタクトピン7が同軸ケーブル8と直角方向に構成されるL型同軸プラグ20にも適用できることは言うまでもない。
In addition, since the split piece 11 is structured to hold the male screw portion 10a of the receptacle 41, even if the screwing between the female screw portion 9 and the male screw portion 10a is forgotten, the same coupling as the conventional one is provided. Strength can be maintained.
Embodiment 2
In addition, the present invention is not limited to the coaxial plug 1 in which the contact pin 7 of the coaxial plug 1 is configured in line with the coaxial cable 8 as described above. For example, the coaxial plug 1 as shown in FIG. Needless to say, the present invention can also be applied to an L-shaped coaxial plug 20 in which the contact pin 7 is configured in a direction perpendicular to the coaxial cable 8.

図4において、L型同軸プラグ20は、把持部4、セレーション13、円筒部材3、分割片11、リング19等から構成される。L型同軸プラグ20における同軸ケーブル8とコンタクトピン7との接続方法は図1の同軸プラグ1と同様であるので、詳細な説明を省略する。   In FIG. 4, the L-shaped coaxial plug 20 includes a grip portion 4, a serration 13, a cylindrical member 3, a split piece 11, a ring 19 and the like. Since the connection method of the coaxial cable 8 and the contact pin 7 in the L-shaped coaxial plug 20 is the same as that of the coaxial plug 1 of FIG. 1, detailed description thereof is omitted.

図5は、L型同軸プラグ20の内部構造の断面を示す図である。図5においては、図2に示す同軸プラグ1と比べ、把持部4は同軸ケーブル8に沿ってL型に構成される。L型同軸プラグ20は、同軸ケーブル8をコンタクトピン7に対してL型に接続する以外は、図2に示す同軸プラグ1と同じであるので詳細な説明を省略する。なお、図5の先端部12の傾斜部3bの部分は理解を容易にするために端面図で表示してある。   FIG. 5 is a view showing a cross section of the internal structure of the L-shaped coaxial plug 20. In FIG. 5, the grip portion 4 is configured in an L shape along the coaxial cable 8 as compared with the coaxial plug 1 shown in FIG. 2. Since the L-type coaxial plug 20 is the same as the coaxial plug 1 shown in FIG. 2 except that the coaxial cable 8 is connected to the contact pin 7 in an L-shape, detailed description thereof is omitted. In addition, the part of the inclined part 3b of the front-end | tip part 12 of FIG. 5 is displayed with the end view for easy understanding.

図5におけるL型同軸プラグ20は、図1の同軸プラグ1と同様に、分割片11、リング19、セレーション13および雌ネジ部9等を有し、分割片11をリセプタクル41の雄ネジ部10aに挿入後、セレーション13を回転させることによって、円筒部材3が回転し、雌ネジ部9とリセプタクル41の雄ネジ部10aとが螺合される。   The L-shaped coaxial plug 20 in FIG. 5 has a split piece 11, a ring 19, a serration 13, a female screw portion 9, etc., like the coaxial plug 1 in FIG. 1, and the split piece 11 is a male screw portion 10 a of the receptacle 41. After the insertion, the cylindrical member 3 is rotated by rotating the serration 13, and the female screw portion 9 and the male screw portion 10 a of the receptacle 41 are screwed together.

L型同軸プラグ20の円筒部材3周辺の構造は、図2に示される構造と同一であり、従ってその効果も図1の同軸プラグ1と同様である。
実施形態3
また、本発明は、例えば、図6に示すようなケース31に設けられる同軸プラグ1のコンタクトピン7がリセプタクル18と直角方向に構成されるT型分配器30にも適用できることは言うまでもない。
The structure around the cylindrical member 3 of the L-shaped coaxial plug 20 is the same as the structure shown in FIG. 2, and therefore the effect is the same as that of the coaxial plug 1 of FIG.
Embodiment 3
Needless to say, the present invention can also be applied to, for example, a T-type distributor 30 in which the contact pin 7 of the coaxial plug 1 provided in the case 31 as shown in FIG. 6 is configured in a direction perpendicular to the receptacle 18.

図6において、T型分配器30は、ケース31、リセプタクル18、芯線32,セレーション13、円筒部材3、分割片11、リング19等から構成される。T型分配器30においては、セレーション13、円筒部材3、分割片11、リング19から構成される部分は図1の同軸プラグ1と同じである。図1との相違点は、コンタクトピン7とリセプタクル18の芯線32とが図7に示すように直角に結合されている点である。   In FIG. 6, the T-type distributor 30 includes a case 31, a receptacle 18, a core wire 32, a serration 13, a cylindrical member 3, a split piece 11, a ring 19, and the like. In the T-type distributor 30, the portion composed of the serration 13, the cylindrical member 3, the split piece 11, and the ring 19 is the same as that of the coaxial plug 1 of FIG. The difference from FIG. 1 is that the contact pin 7 and the core wire 32 of the receptacle 18 are coupled at right angles as shown in FIG.

図7はT型分配器30の内部構造の詳細断面を示す図である。図7においては、T型分配器30は、ケース31、リセプタクル18、コンタクトピン受け導体26、コンタクトピン受け孔27、芯線32,芯線17a、インピーダンス整合部14、セレーション13、円筒部材3、分割片11、絶縁部5、リング19等から構成される。ケース31と同軸プラグとの間は、圧入外環15に設けられた雄ねじ21と、ケース31に設けられ図示されていない雌ねじ間で結合される。絶縁体5はコンタクトピン7を支持する部材として作用する。コンタクトピン7とリセプタクル18の芯線32は、インピーダンス整合部14を介してインピーダンス整合が行われ、コンタクトピン7からの信号は、芯線32と整合が取られリセプタクル18から出力される。T型分配器30は、ケース31、インピーダンス整合部14、リセプタクル18、雄ネジ21以外は図2に示す同軸プラグ1と同じであるので詳細な説明を省略する。   FIG. 7 is a view showing a detailed cross section of the internal structure of the T-type distributor 30.

The case 31 and the coaxial plug are coupled between a male screw 21 provided in the press-fit outer ring 15 and a female screw provided in the case 31 and not shown. The insulator 5 acts as a member that supports the contact pin 7. Impedance matching is performed between the contact pin 7 and the core wire 32 of the receptacle 18 via the impedance matching unit 14, and the signal from the contact pin 7 is matched with the core wire 32 and output from the receptacle 18. The T-type distributor 30 is the same as the coaxial plug 1 shown in FIG. 2 except for the case 31, the impedance matching unit 14, the receptacle 18, and the male screw 21, and thus detailed description thereof is omitted.

図7におけるT型分配器30においては、図1の同軸プラグ1と同様に、分割片11をリセプタクル41の雄ネジ部10aに挿入後、セレーション13を回転させることによって、円筒部材3が回転し、雌ネジ部9とリセプタクル41の雄ネジ部10aとが螺合される。図7に示されるT型分配器30においては、コンタクトピン7から入力される信号は分配器の他の分岐部に設けられた2つのリセプタクル18に分配され、そこから他の装置に信号が供給される。なお、コンタクトピン7がリセプタクル18と直角以外の角度を有する分配器にも本願発明は用いられることができることも言うまでもない。   In the T-type distributor 30 in FIG. 7, the cylindrical member 3 is rotated by rotating the serration 13 after inserting the split piece 11 into the male screw portion 10a of the receptacle 41, as in the coaxial plug 1 in FIG. The female screw portion 9 and the male screw portion 10a of the receptacle 41 are screwed together. In the T-type distributor 30 shown in FIG. 7, a signal input from the contact pin 7 is distributed to two receptacles 18 provided at other branch portions of the distributor, and signals are supplied from there to other devices. Is done. Needless to say, the present invention can also be used in a distributor in which the contact pin 7 has an angle other than a right angle with respect to the receptacle 18.
