Description

本発明は，主にテレビ受信システムに利用される同軸Ｆ型コネクタ座に摺動固着して取付ける同軸ケーブルコネクタに関し，詳しくはその接続作業が簡単で，且つ，同軸ケーブルを引っ張っても引き抜けがたく，その上で，取外作業の容易な同軸ケーブルコネクタの構造に関する。
The present invention relates to a coaxial cable connector that is slidably fixed to a coaxial F-type connector seat mainly used in a television reception system. Specifically, the connection work is simple and the coaxial cable can be pulled out even if it is pulled. In addition, it relates to the structure of a coaxial cable connector that can be easily removed.

従来において提案されている同軸ケーブルコネクタは，同軸Ｆ型コネクタ座に挿入して用いられる接栓において，同軸ケーブルを内部中心に保持するスリーブと，このスリーブの先端外周に嵌合して設けられ，更に先端方向に伸び出して設けられたリング状シェルと，径方向内側に軸方向後端側が立ち上がった複数の切起しを有し，前記リング状シェルの内周に嵌装された，リング状内ばねと，前記リング状シェルの先端を包むように前記接栓の軸方向に移動可能に嵌装され，前記接栓の径方向内側にあり軸方向後端側に伸びた端部が前記リング状内ばねの切起しを押圧し得るように構成されたキャップと，を備えた同軸ケーブルコネクタが提案されており，この同軸ケーブルコネクタは，一般的なねじ溝が形成された同軸Ｆ型コネクタ座に対して接続するには，シェルを軸方向に移動させるだけで回転操作の必要がないので，接続作業の時間短縮が図れるばかりでなく，接続後は前記リング状内ばねの切起しがコネクタ座のねじ溝に嵌まり込み同軸コネクタを引き抜け難いものにしている。更には，この同軸コネクタに備えられたキャップをコネクタの軸方向に座から離れるように引く操作によって，キャップの前記接栓方向内側に延びた端部が，前記リング状内ばねに形成した切起しを押圧して切起しを寝かせることから，切起しは前記座のねじ溝から解放されることになり，コネクタ座から簡単に外すことができるのである。

しかし，従来の同軸コネクタによると，その接続作業においては，挿入開始時点から挿入終了時点までの間，切起しとねじとの嵌合が必要であり，この挿入に対して相応の力が必要であった。また，取外作業においては，シェルがコネクタ座から抜けるまで切起しを押圧するためのキャップを引いている必要があり，指先を使っての適度な引っ張り力で取外しが行われるには，前記リング状内ばねの材質や切起しの角度や寸法等の最適化が設計においてなされる必要があった。
また，該キャップで前記切起しを押圧するためには，キャップが軸方向に移動可能に構成されている必要があり，これによってキャップを含めた軸方向の寸法が大きくなるといった問題があった。更に加えて，キャップがコネクタの軸方向前方に突設されていることから，この同軸ケーブルコネクタを取付対象である同軸Ｆ型コネクタ座に取付けたときに，該コネクタ座の取付け面が前記キャップに接触しない（言い換えれば押付けない）ように，コネクタ座の軸方向の寸法を長くするなどの必要性があり，取付け対象であるコネクタ座に対する汎用性の点においても問題があった。
また，このような方法では，前記切起しを押圧するためのキャップのコストがかかるばかりでなく，キャップの嵌装に対する組み立て工賃もかかることになり，延いては製品のコストが高くなるといった問題があった。

However, according to the conventional coaxial connector, in the connection work, it is necessary to fit the notch and the screw between the insertion start time and the insertion end time, and an appropriate force is required for this insertion. Met. Also, in the removal work, it is necessary to pull a cap for pressing the raising and lowering until the shell comes off the connector seat, and in order to remove it with an appropriate pulling force using a fingertip, It was necessary to optimize the material of the ring-shaped inner spring, the angle and dimension of the cut and raised in the design.
Further, in order to press the cut and raised with the cap, the cap needs to be configured to be movable in the axial direction, which causes a problem that the axial dimension including the cap increases. . In addition, since the cap protrudes forward in the axial direction of the connector, when the coaxial cable connector is attached to the coaxial F-type connector seat to be attached, the attachment surface of the connector seat is attached to the cap. There is a need to lengthen the dimension of the connector seat in the axial direction so that it does not contact (in other words, it does not push), and there is also a problem in terms of versatility with respect to the connector seat to be mounted.
In addition, such a method not only costs the cap for pressing the cut and raised, but also costs an assembly fee for fitting the cap, which in turn increases the cost of the product. was there.
Therefore, in this application, it was made to solve these problems.

上記課題を解決するために，請求項１の発明は，同軸Ｆ型コネクタ座に摺動固着して用いられる同軸ケーブルコネクタにおいて，同軸ケーブルの編組導体と接続する筒状のスリーブと，後端側が前記スリーブの基端部に枢着されたリング状シェルと，該リング状シェルの内周に嵌装され，前記同軸Ｆ型コネクタ座に摺動固着するためのリング状内ばねであって，後端部から径方向内側に軸方向後端側が立ち上がった１又は複数の切起片と，後端部から軸方向に突出し前記リング状シェルと係合するための１又は複数の係合片とを備えたリング状内ばねと，前記同軸ケーブルに前記シェルを挿入後，該シェルの挿入部を圧着固定する固着リングとを備えて構成した。
In order to solve the above-mentioned problems, the invention of claim 1 is directed to a coaxial cable connector that is slidably fixed to a coaxial F-type connector seat, a cylindrical sleeve connected to a braided conductor of the coaxial cable, and a rear end side thereof. A ring-shaped shell pivotally attached to a base end portion of the sleeve, and a ring-shaped inner spring that is fitted to the inner periphery of the ring-shaped shell and is slidably fixed to the coaxial F-type connector seat. One or a plurality of cut and raised pieces whose axial rear end side rises radially inward from the end, and one or a plurality of engagement pieces that protrude in the axial direction from the rear end and engage with the ring-shaped shell. A ring-shaped inner spring provided, and a fixing ring that crimps and fixes the insertion portion of the shell after the shell is inserted into the coaxial cable.

請求項１の発明によれば，同軸Ｆ型コネクタ座に摺動固着して用いられる同軸ケーブルコネクタにおいて，同軸ケーブルの編組導体と接続する筒状のスリーブと，後端側が前記スリーブの基端部に枢着されたリング状シェルと，該リング状シェルの内周に嵌装され，前記同軸Ｆ型コネクタ座に摺動固着するためのリング状内ばねであって，後端部から径方向内側に軸方向後端側が立ち上がった１又は複数の切起片と，後端部から軸方向に突出し前記リング状シェルと係合するための１又は複数の係合片とを備えたリング状内ばねと，前記同軸ケーブルに前記シェルを挿入後，該シェルの挿入部を圧着固定する固着リングとを備えて構成したので，
接続の際には，リング状内ばねに形成された切起片とコネクタ座のねじ溝とが嵌合することによって，コネクタ座に対する簡単な挿入操作だけであっても，その接続は，同軸ケーブルの引っ張り力に対しても抜け難く，且つ，電気的特性が安定するように構成されている。
According to the first aspect of the present invention, in the coaxial cable connector used by being slidably fixed to the coaxial F-type connector seat, the cylindrical sleeve connected to the braided conductor of the coaxial cable, and the rear end side is the proximal end portion of the sleeve A ring-shaped shell pivotally attached to the inner periphery of the ring-shaped shell, and a ring-shaped inner spring that is fitted to the inner periphery of the ring-shaped shell and is slidably fixed to the coaxial F-type connector seat. A ring-shaped inner spring comprising one or more cut-and-raised pieces raised on the rear end side in the axial direction, and one or more engaging pieces projecting in the axial direction from the rear end portion and engaged with the ring-shaped shell And, after the shell is inserted into the coaxial cable, and a fixing ring that crimps and fixes the insertion portion of the shell,
At the time of connection, the cut-and-raised piece formed on the ring-shaped inner spring and the thread groove of the connector seat are fitted together, so that the connection can be made even with a simple insertion operation to the connector seat. It is difficult to come out with respect to the pulling force, and the electrical characteristics are stabilized.

更には，前記切起片をリング状内ばねの後端部に形成することで，挿入操作の最終段階で初めてコネクタ座のねじ溝と切起片が嵌合することから，このときに発生するクリック感及びクリック音によって，挿入操作が完全に行われたかどうかが正確，且つ，容易に判定することができるのである。これに伴って，コネクタ座の軸線方向にたいして，挿入開始から完全に挿入完了時点まで，切起片とコネクタ座を摺動させながら挿入する必要がないため，嵌合に係る力が少なくて済むことから，ユーザーにとってより使いやすいコネクタを提供できるのである。また，本発明のように，切起片の嵌合をコネクタ座に対する挿入寸法の内の，最後の部分の出来うる限りの短い寸法範囲で行うことができるように構成したことから，リング状内ばねにおける材料や，切起片の角度，大きさや形状の設計が容易と成り，延いては製品コストを安価にできるといった有効性の高い同軸ケーブルコネクタを提供できるのである。
Furthermore, since the cut and raised piece is formed at the rear end of the ring-shaped inner spring, the thread groove of the connector seat and the cut and raised piece are fitted for the first time in the final stage of the insertion operation. It is possible to accurately and easily determine whether or not the insertion operation has been completely performed based on the click feeling and the click sound. Along with this, since it is not necessary to slide the cut-and-raised piece and the connector seat in the axial direction of the connector seat from the start of insertion to the point of complete insertion, the force required for fitting can be reduced. Therefore, it is possible to provide a user-friendly connector. Further, as in the present invention, since the cut-and-raised piece can be fitted within the shortest possible range of dimensions of the last part of the insertion dimensions with respect to the connector seat, It is possible to provide a highly effective coaxial cable connector that facilitates the design of the spring material, the angle, size, and shape of the cut and raised pieces, which in turn can reduce the product cost.

また，取外しの際には，シェルの回転操作によって取外しができるのであるが，僅かなシェルの回転操作で素早く取外しができるのである。また，例えば切起片を押圧するリリーサーのような特別な構成部材を付加することもないので，構造が簡単で，非常に安価に実現できるのである。
In addition, it can be removed by rotating the shell, but can be quickly removed by slightly rotating the shell. Further, since a special component such as a releaser that presses the cut and raised pieces is not added, the structure is simple and can be realized at a very low cost.

先ず接続は，同軸ケーブルコネクタをコネクタ座１０１に挿入することによってできる。この挿入操作時には前記リング状内ばね５０の内面とコネクタ座１０１の外周とが摺動固着されるように構成されている。このとき該リング状内ばね５０の略中央部には，径方向内側に向けて形成された複数の前記ばね部５１と，該リング状内ばね５０の後端部には径方向内側に軸方向後端側が立ち上がった複数の切起片５１が形成されていることから，コネクタの挿入操作と共に前記ばね部５１はコネクタ座１０１の外周面に形成されたねじ山に弾性力によって接触しながら挿入される。更にコネクタを挿入操作していくと，挿入の最終段階において前記複数の切起片５１は前記コネクタ座に形成されたねじ山を越えてねじ溝に嵌まり込むように構成されているのである。
尚，この図に示す実施例における切起片５２とねじ溝の嵌まり込み状態は１実施例を示したものであり，特にこの位置に限定されるものではない。
FIG. 3 is an enlarged partial cross-sectional view of a main part showing a connection state when a connector fitted with the coaxial cable 10 is connected to the coaxial F-type connector seat, and using this, the coaxial cable connector according to the present application is connected to the connector seat. Connection and disconnection procedures are shown.
First, the connection can be made by inserting a coaxial cable connector into the connector seat 101. During this insertion operation, the inner surface of the ring-shaped inner spring 50 and the outer periphery of the connector seat 101 are configured to be slidably fixed. At this time, the ring-shaped inner spring 50 has a plurality of spring portions 51 formed radially inward at a substantially central portion thereof, and a rear end portion of the ring-shaped inner spring 50 axially radially inward. Since a plurality of cut and raised pieces 51 whose rear end side rises are formed, the spring portion 51 is inserted while being in contact with the thread formed on the outer peripheral surface of the connector seat 101 by elastic force as the connector is inserted. The When the connector is further inserted, the plurality of cut-and-raised pieces 51 are configured to fit into the thread groove beyond the thread formed on the connector seat in the final stage of insertion.
It should be noted that the cut-and-raised piece 52 and the thread groove fitting state in the embodiment shown in this figure is one embodiment, and is not particularly limited to this position.

次に取外しを行う場合について説明する。コネクタをコネクタ座に装着した状態では，前記切起片５１の先端部が前記コネクタに形成したねじ溝に嵌まり込んだ状態であるので，コネクタの引き抜き操作では引き抜くことができない。ところが，上記に詳述したようにリング状内ばね５０は，該内ばねの後端から軸方向に向かって係合片５２が形成されると共に，このリング状内ばねに形成した係合片５２が，リング状シェル２０内の止部２３に形成した凹部２４に挿入さるように前記リング状シェル２０内に嵌装されていることから，前記リング状シェル２０とリング状内ばね５０とは相互に係合されて，シェルの回転操作に合わせて内ばねも回転するように構成されているので，取外しの際には，シェルを回転操作することによって，前記切起片５１と前記コネクタ座１０１のねじとの螺合を解放できるのである。
Next, the case of removing will be described. When the connector is mounted on the connector seat, the tip of the cut-and-raised piece 51 is in a state of being fitted into a screw groove formed in the connector, and therefore cannot be pulled out by the connector pull-out operation. However, as described in detail above, the ring-shaped inner spring 50 has an engagement piece 52 formed in the axial direction from the rear end of the inner spring, and the engagement piece 52 formed on the ring-shaped inner spring. Is inserted in the ring-shaped shell 20 so as to be inserted into the recess 24 formed in the stop 23 in the ring-shaped shell 20, the ring-shaped shell 20 and the ring-shaped inner spring 50 are mutually connected. Since the inner spring is also rotated in accordance with the rotation operation of the shell, when the shell is removed, the cut and raised piece 51 and the connector seat 101 are rotated by rotating the shell. It is possible to release the screw engagement with the screw.

以上本発明の同軸ケーブルコネクタにおいては，接続の際には，リング状内ばね５０に形成されたばね部５１と切起片５１によって，コネクタ座に対して簡単な挿入操作だけででき，その接続においては同軸ケーブルの引っ張り力に対しても抜け難く且つ電気的特性が安定するように構成されている。
また，切起片５１の形成されている位置が，コネクタ座の先端部からコネクタ座の基部に向かって少し軸方向に入ったところのねじ溝に嵌まり込むように構成されていることから，挿入操作の最終段階で初めてコネクタ座のねじ溝と切起片５１が嵌合することになり，このときに発生するクリック感及びクリック音によって，挿入操作が完全に行われたかどうかが正確，且つ，容易に判定することができるのである。加えて，従来例の如くコネクタ座の軸線方向の長さ部分を嵌合させながら挿入する必要がないため，嵌合に係る力が少なくて済むことから，ユーザーにとってより使いやすいコネクタを提供できるのである。
また，このように切起片５１の嵌合をコネクタ座に対する挿入開始時点から挿入終了時点まで行う必要がないことから，リング状内ばね５０における材料や，切起片５１の角度，大きさや形状の設計が容易と成り，延いては製品コストを安価にできるといった有効性の高い同軸ケーブルコネクタを提供できるのである。
また，コネクタ座の外部導体を，例えば金属材料をプレス加工してなる廉価なテレビ端子等の機器にも同じように接続できることから，汎用性の高い同軸ケーブルコネクタを提供できるのである。
尚，図４に本発明の同軸ケーブルコネクタを，同軸Ｆ型コネクタ座を備えた電子機器に取付けたときの状態を示し，（ａ）は引き抜け方向の力が加わった場合の模式図であり，（ｂ）は左右方向に力が加わった場合の模式図である。この図において１００は電子機器筐体である。
As described above, in the coaxial cable connector of the present invention, when connecting, the spring portion 51 and the cut and raised piece 51 formed on the ring-shaped inner spring 50 can be simply inserted into the connector seat. Is configured so that it is difficult to come out with respect to the pulling force of the coaxial cable and the electrical characteristics are stabilized.
Further, since the position where the cut-and-raised piece 51 is formed is configured to fit into the screw groove that is slightly in the axial direction from the tip of the connector seat toward the base of the connector seat, For the first time at the final stage of the insertion operation, the thread groove of the connector seat and the cut-and-raised piece 51 are fitted, and the click feeling and the click sound generated at this time are accurate to confirm whether or not the insertion operation has been performed completely. , Can be easily determined. In addition, it is not necessary to insert the length of the connector seat in the axial direction as in the conventional example, so that it is possible to provide a connector that is easier for the user to use because less force is required for the fitting. is there.
Further, since it is not necessary to perform the fitting of the cut and raised pieces 51 from the insertion start time to the insertion end time with respect to the connector seat, the material of the ring-shaped inner spring 50, the angle, the size and the shape of the cut and raised pieces 51 are used. Therefore, it is possible to provide a highly effective coaxial cable connector that can reduce the product cost.
Further, since the outer conductor of the connector seat can be connected in the same manner to an inexpensive device such as a television terminal formed by pressing a metal material, for example, a highly versatile coaxial cable connector can be provided.
FIG. 4 shows a state when the coaxial cable connector of the present invention is attached to an electronic device equipped with a coaxial F-type connector seat, and FIG. 4A is a schematic diagram when a force in the pull-out direction is applied. , (B) is a schematic diagram when a force is applied in the left-right direction. In this figure, reference numeral 100 denotes an electronic device casing.

また，取外しの際には，シェルの回転操作によって取外しができるのであるが，前記切起片５１が前記コネクタ座１０１のねじ溝に嵌め込まれた位置が，コネクタ座の先端部に近い位置にあり，該コネクタ座の軸方向に対する寸法より非常に短いことから，僅かなシェルの回転操作によって素早く取外しができるのである。また，例えば切起片５１を押圧するリリーサのような特別な構成部材を付加することもないので，構造が簡単で，非常に安価に実現できるのである。
また，これによってリリーサを軸方向に動かすための空間を必要としないので同軸ケーブルコネクタの長手方向の寸法を小さくできるばかりでなく，リリーサがコネクタ座の取付け面によって押付けられて，コネクタが緩んでしまうといった問題の心配もないので，既に出回っている機器に取付けられている同軸Ｆ型コネクタ座に対しても利用できる汎用性の高い同軸ケーブルコネクタを提供できるのである。

尚，本発明は上記実施の形態に限定されるものではなく，例えば切起片や係合片は1又は複数個を適宜に配設して形成してもよい等，本発明の趣旨を逸脱しない範囲で各部の構成を適宜に変更して実施することも可能である。
Further, when removing, the shell can be removed by rotating the shell. However, the position where the cut and raised piece 51 is fitted in the screw groove of the connector seat 101 is close to the tip of the connector seat. Because the connector seat is much shorter than the axial dimension, it can be quickly removed by slightly rotating the shell. Further, since a special component such as a releaser that presses the cut and raised piece 51 is not added, the structure is simple and can be realized at a very low cost.
In addition, this eliminates the need for a space for moving the releaser in the axial direction, so that not only the longitudinal dimension of the coaxial cable connector can be reduced, but also the releaser is pressed by the mounting surface of the connector seat and the connector is loosened. Therefore, it is possible to provide a highly versatile coaxial cable connector that can be used for a coaxial F-type connector seat that is already installed on a device.

The present invention is not limited to the above-described embodiment. For example, one or a plurality of cut and raised pieces and engagement pieces may be formed as appropriate. It is also possible to carry out by appropriately changing the configuration of each part within the range not to be.
