Description

【0001】
【発明の属する技術分野】
本発明は、通信用同軸ケーブルの接続に用いられるコネクタ、特に、外部導体が筒状を成し、内部導体が棒状を成す構造の同軸ケーブルに用いるに最適な同軸ケーブル用コネクタに関するものである。
【0002】
【従来の技術】
図7は従来の同軸ケーブル用コネクタを示す断面図である。
同軸ケーブル201は、図8に示すように、芯線となる内部導体202、この内部導体202の外側に同軸に形成される絶縁体203、この絶縁体203の外側に設けられる波付けの外部導体204、この外部導体204を被覆するシース205から構成されている。
【0003】
同軸ケーブル201に接続されるコネクタ206は、図7に示すように、内部導体202の先端部が挿入される内部導体207、この内部導体207の外側に設けられて外部導体204の先端部に当接するように絶縁リング208を介して配設されるワッシャ209、同軸ケーブル201の外部導体204を取り巻くように配設されるカラー210、これらの各部材を覆うように設けられる外筺部211、この外筺部211にねじ込まれる締め付けリング212、この締め付けリング212とカラー210との間に配設されるゴムリング213の各々を備えて構成されている。
【0004】
このコネクタ206を同軸ケーブル201に装着するに際しては、まず、同軸ケーブル201を図8の様に加工する。この場合、内部導体202の露出長さを正確に切り出す。また、締め付けリング212は末装着にしておく。次に、締め付けリング212及びゴムリング213を同軸ケーブル201のシース205に外嵌し、更に外部導体204にカラー210及びワッシャ209を外嵌する。この状態のまま、同軸ケーブル201の内部導体202の先端をコネクタ206の内部導体207の凹部に挿入し、内部導体207と同軸ケーブル201の内部導体202の電気的接続を行う。そして、同軸ケーブル201の全体がそれ以上押し込めなくなった時点で外筺部211内にゴムリング213を押し込み、更に、締め付けリング212をねじ込むことにより装着が完了する。
【0005】
【発明が解決しようとする課題】
しかし、上記した従来技術にあっては、以下のような問題を有している。
(1) 同軸ケーブルにコネクタを取り付ける際、事前にケーブルの寸法出し加工が必要であるため、ケーブルの外部導体と内部導体をコネクタにワンタッチで接続することができない。
(2) 同軸ケーブルの外部導体とコネクタの外部導体を接続する際、同軸ケーブルのシースを剥ぐ必要がある。
(3) 同軸ケーブルの内部導体とコネクタの内部導体とを接続する際、同軸ケーブルの内部導体を絶縁層より長い寸法に加工し、取付時には半田付け、ねじ締め、或いは内部導体を覆うように挿入させる構造にする必要がある。
【0006】
そこで本発明は、同軸ケーブルにコネクタをワンタッチで取り付けることのできる同軸ケーブル用コネクタを提供することを目的としている。
【0007】
【課題を解決するための手段】
上記の目的を達成するために、この発明は、中空部を有した本体と、前記本体の前記中空部の開口端の外周に回転自在に係着される円筒状の雌ねじと、端面が平面にカットされた同軸ケーブルを内挿でき、その内挿後に前記同軸ケーブルを固定手段によって堅持し、かつ前記雌ねじとの結合が強まるにつれて前記本体側へ移動する円筒状の締付金具と、前記同軸ケーブルの中実内部導体に対して先端面が圧接可能に配設される押圧部材を移動可能に内嵌して前記本体の前記中空部内の軸心部に設置されるコネクタ側内部導体と、前記本体の前記中空部内において前記押圧部材と絶縁されながら同軸に配設され、前記同軸ケーブルの波形外部導体の切断端面に食い込む少なくとも1つの突起を備えたカラーとを具備した構成にしている。
また、本発明は上記の目的を達成するため、同軸ケーブルの内部導体、絶縁体、外部導体、及びシースを切断して前記同軸ケーブルの中心軸と直交する平面を形成する段階と、
中心軸上に内部導体機構を有する本体に外嵌するナットとねじ係合する締付金具の中空部に前記平面を形成された前記同軸ケーブルを内挿して前記締付金具を前記同軸ケーブルの外周面に固定する段階と、
前記ナットを締め方向へ回転させることにより前記本体を前記同軸ケーブルの前記平面に近接させる軸方向に移動させ、この移動により前記本体の内部に前記内部導体機構と絶縁して配置された切刃カラーの切刃を前記軸方向に移動させて前記切刃を前記平面における前記外部導体に食い込ませ、かつ、前記内部導体機構の押圧部材を前記同軸ケーブルの前記平面における前記内部導体に圧接させる段階を有することを特徴とする同軸ケーブルへのコネクタの接続方法を提供する。
【0008】
この構成によれば、同軸ケーブルに締付金具を外嵌し、これを同軸ケーブルに締め付けた後、本体側に挿入し、本体側に設けられた雌ねじと締付金具とを螺合させる。この螺合が強まるにつれ、締付金具及び同軸ケーブルはコネクタの本体内へ進入する。その過程で、同軸ケーブルの外部導体にカラーの突起が食い込み、同軸ケーブルの内部導体に押圧部材の先端面が圧接する。この結果、コネクタの装着がワンタッチで行え、かつ確実な接続が可能になる。
【0009】
そして、前記押圧部材は、前記コネクタ側内部導体内に配設された附勢部材によって前記同軸ケーブル方向に附勢されている。
この構成によれば、コネクタ側内部導体内に配設された附勢部材は、同軸ケーブル方向に押し出すような附勢力を押圧部材に付与する。この結果、押圧部材の先端面は常に同軸ケーブルの内部導体に圧接し、確実な電気的接触が得られる。また、誰が装着しても、接触状態にばらつきを生じることがない。
【0010】
【発明の実施の形態】
図1は本発明による同軸ケーブル用コネクタの一実施の形態を示す断面図である。
図1に示すように、本発明によるコネクタ100は、同軸ケーブル201の外径にほぼ等しい内径を有する筒状の締付金具101、この締付金具101の中央部に設けられた溝102内に嵌入されるOリング103、締付金具101の外周面に取り付けられるクランプ104,105、締付金具101の一端にねじ結合されるリング状のナット106、このナット106を一端の外周部に装着した本体107、この本体107の端部のナット106に対向する部位に配設される図2に示す構成の切刃カラー108、この切刃カラー108に隣接かつ同軸に配置されるリング状の絶縁体109、この絶縁体109と同軸にして本体107の他端の内部に配設される小径の絶縁体110、及び図3に示す内部導体機構の各々を備えて構成される。ここで、絶縁体109と絶縁体110は、後記する内部導体機構を支持する働きをする。
【0011】
図2に示すように、切刃カラー108は同軸ケーブル側に複数の切刃(3角形の突起)108aが設けられており、(a)図は側面図であり、(b)図は(a)図のA−A断面図である。
図3に示すように、内部導体機構は、糸巻形の断面形状を有して軸心部に配設される押しピン111(押圧部材)、この押しピン111を一端に内挿する中空部112が一端に形成されると共に他端にスリット113bを有した中空溝113aが形成された内部導体113、中空溝113aに挿入された押しピン111の奥部に内装されて押しピン111を押し出す附勢力を持つコイルスプリング114(附勢部材)、締付金具101の胴部に嵌入されて内部導体113の内面との電気的接続を確実にする接続ばね115の各々を備えて構成されている。接続ばね115は、図4に示すように中央部が膨出し、円周方向に一定間隔にスリット115aが設けられた構成を有している。そして、接続ばね115は押しピン111に外嵌され、その一端は押しピン111の端部に固定されている。
【0012】
以上の構成において、同軸ケーブル201とコネクタ100を接続する場合、同軸ケーブル201の端部を図5に示すように処理する。すなわち、ケーブル端部は、鋸やカッターでフラットにカットされ、従来のようにシース205を剥いで外部導体204を露出させたり、内部導体202を所定の長さにカットする処理は不必要になる。
【0013】
このように処理した同軸ケーブル201に締付金具101を適当な位置まで嵌め込み、クランプ104,105を締め付けて固定する。この状態のまま、同軸ケーブル201をナット106に位置合わせし、ナット106を締め方向へ回転させる。この回転に伴って締付金具101は本体107に進入して行く過程で、外部導体204に切刃カラー108の切刃108aが図6に示す様に食い込み、外部導体204と切刃カラー108の電気的な接続が行われる。このとき、シース205が外部導体204と切刃カラー108の間に挟み込まれたとしても、締付金具101が締め込まれる過程で切刃108aがシース205を切断し、外部導体204と切刃カラー108の電気的接触が可能になる。また、内部導体202はコイルスプリング114によって附勢されている押しピン111の端面に圧接し、両者の電気的接続が行われる。このとき、接続ばね115は押しピン111と内部導体113の接続を確実にし、接触不良の発生を防止するように機能する。
【0014】
以上のように、本発明によれば、同軸ケーブル201の端部を平面状態にカットし、これに締付金具101を嵌め込み、コネクタ本体107に挿入し、締付金具101とコネクタ本体107を結合するためのナット106を回転させるのみでコネクタの装着が完了する。この結果、コネクタの装着がワンタッチで行え、放送設備、通信設備等におけるケーブル事故の発生時の緊急復旧対策用に用いた場合、装着が迅速に行え、しかも取扱者が変わっても特性に個人差が生ぜず、確実に装着することができる。
【0015】
【発明の効果】以上より明らかな如く、本発明によれば、同軸ケーブルに締付金具を外嵌し、これを同軸ケーブルに締め付けた後に本体側に挿入し、本体側に設けられた雌ねじと締付金具とを螺合させ、その螺合が強まるにつれ、締付金具及び同軸ケーブルはコネクタの本体内へ進入できるようにし、その進入過程で同軸ケーブルの波型の外部導体にカラーの突起が食い込み、かつ同軸ケーブルの中実の内部導体には押圧部材の先端面が圧接する構成にしたので、コネクタの装着がワンタッチで行え、かつ確実な接続が可能になる。

[0005]
[Problems to be solved by the invention]
However, the above-described prior art has the following problems.
(1) When attaching a connector to a coaxial cable, the cable must be dimensioned in advance, so that the outer conductor and the inner conductor of the cable cannot be connected to the connector with one touch.
(2) When connecting the outer conductor of the coaxial cable to the outer conductor of the connector, it is necessary to peel off the sheath of the coaxial cable.
(3) When connecting the inner conductor of the coaxial cable and the inner conductor of the connector, process the inner conductor of the coaxial cable to a dimension longer than the insulating layer, and solder or screw it in during installation or insert it so as to cover the inner conductor. It is necessary to make it a structure to make it.
[0006]
Therefore, an object of the present invention is to provide a connector for a coaxial cable in which the connector can be attached to the coaxial cable with one touch.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a main body having a hollow portion, a cylindrical female screw rotatably fixed to an outer periphery of an open end of the hollow portion of the main body, and an end surface formed into a flat surface. A cylindrical fastener that can insert the cut coaxial cable, hold the coaxial cable by fixing means after the insertion, and move toward the main body as the coupling with the female screw increases; and the coaxial cable. A connector-side inner conductor, which is movably fitted with a pressing member whose tip end surface is arranged to be able to press against the solid inner conductor, and which is installed at an axial center in the hollow portion of the main body; And a collar having at least one projection that is coaxially disposed in the hollow portion while being insulated from the pressing member and that cuts into a cut end surface of the corrugated outer conductor of the coaxial cable.
Further, in order to achieve the above object, the present invention, the inner conductor of the coaxial cable, the insulator, the outer conductor, and cutting the sheath to form a plane orthogonal to the central axis of the coaxial cable,
The coaxial cable having the flat surface formed therein is inserted into a hollow portion of the fastener which is screw-engaged with a nut externally fitted to a main body having an inner conductor mechanism on a center axis, and the fastener is connected to the outer periphery of the coaxial cable. Fixing to the surface,
By rotating the nut in the tightening direction, the main body is moved in the axial direction so as to approach the plane of the coaxial cable, and the movement causes the cutting edge collar to be arranged in the body and insulated from the internal conductor mechanism. Moving the cutting edge in the axial direction so that the cutting edge bites into the outer conductor in the plane, and presses the pressing member of the inner conductor mechanism against the inner conductor in the plane of the coaxial cable. A method for connecting a connector to a coaxial cable is provided.
[0008]
According to this configuration, the fastening fitting is externally fitted to the coaxial cable, and after fastening this to the coaxial cable, it is inserted into the main body side, and the female screw provided on the main body side and the fastening fitting are screwed together. As the screwing increases, the fastener and the coaxial cable enter the body of the connector. In the process, the protrusion of the collar bites into the outer conductor of the coaxial cable, and the tip end surface of the pressing member presses against the inner conductor of the coaxial cable. As a result, the connector can be mounted with one touch, and a reliable connection can be achieved.
[0009]
The pressing member is urged in the direction of the coaxial cable by an urging member provided in the connector-side internal conductor.
According to this configuration, the urging member provided in the connector-side inner conductor applies an urging force to the pressing member so as to push the pressing member in the coaxial cable direction. As a result, the distal end surface of the pressing member always presses against the inner conductor of the coaxial cable, and reliable electrical contact is obtained. Also, no matter who wears it, there is no variation in the contact state.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a sectional view showing an embodiment of a coaxial cable connector according to the present invention.
As shown in FIG. 1, a connector 100 according to the present invention includes a cylindrical fastener 101 having an inner diameter substantially equal to the outer diameter of a coaxial cable 201 and a groove 102 provided at a central portion of the fastener 101. An O-ring 103 to be fitted, clamps 104 and 105 attached to the outer peripheral surface of the fastener 101, a ring-shaped nut 106 screwed to one end of the fastener 101, and the nut 106 mounted on an outer peripheral portion of one end. A main body 107, a cutting edge collar 108 having a configuration shown in FIG. 2 disposed at a position facing the nut 106 at an end of the main body 107, and a ring-shaped insulator adjacent to and coaxial with the cutting edge collar 108. 109, a small-diameter insulator 110 disposed coaxially with the insulator 109 inside the other end of the main body 107, and an internal conductor mechanism shown in FIG. Here, the insulator 109 and the insulator 110 serve to support an internal conductor mechanism described later.
[0011]
As shown in FIG. 2, the cutting blade collar 108 has a plurality of cutting blades (triangular protrusions) 108a provided on the coaxial cable side. FIG. 2A is a side view, and FIG. FIG.
As shown in FIG. 3, the inner conductor mechanism has a pin-shaped cross-sectional shape and a push pin 111 (press member) disposed at an axial center portion, and a hollow portion 112 into which one end of the push pin 111 is inserted. Is formed at one end and an inner conductor 113 having a hollow groove 113a having a slit 113b formed at the other end, and an urging force for pushing the push pin 111 by being housed inside a push pin 111 inserted into the hollow groove 113a. And a connection spring 115 that is fitted into the body of the clamp 101 and ensures electrical connection with the inner surface of the internal conductor 113. As shown in FIG. 4, the connection spring 115 has a configuration in which a central portion bulges and slits 115a are provided at regular intervals in a circumferential direction.

An electrical connection is made. At this time, even if the sheath 205 is sandwiched between the outer conductor 204 and the cutting blade collar 108, the cutting blade 108a cuts the sheath 205 in the process of tightening the fastener 101, and the outer conductor 204 and the cutting blade collar 108 are cut. 108 electrical contacts are enabled. Further, the inner conductor 202 is pressed against the end face of the push pin 111 urged by the coil spring 114, and the two are electrically connected.

The mounting of the connector is completed only by rotating the nut 106 for mounting. As a result, the connector can be mounted with a single touch, and when used for emergency recovery measures in the event of a cable accident in broadcasting equipment, communication equipment, etc., the connector can be mounted quickly, and even if the operator changes, the characteristics differ among individuals. Does not occur and can be securely attached.
[0015]
As is apparent from the above description, according to the present invention, a clamp is externally fitted to a coaxial cable, which is fastened to the coaxial cable and then inserted into the main body, and the female screw provided on the main body is connected to the female screw. The fastener and the coaxial cable are allowed to enter into the main body of the connector as the screwing is strengthened, and the corrugated outer conductor of the coaxial cable has a collar protrusion during the entry process. Since the distal end surface of the pressing member is pressed into contact with the solid inner conductor of the coaxial cable, the connector can be mounted with one touch and reliable connection can be made.
