Description

本発明は，同軸ケーブルの端部に装着する同軸ケーブルコネクタの構造に関する。
The present invention relates to a structure of a coaxial cable connector attached to an end portion of a coaxial cable.

従来，同軸ケーブルの端部に装着する，円筒部材の中心にコンタクトピンを配置してなる同軸プラグにおいて，接続対象であるＦ型レセプタクルの外周面に形成された雄ネジの先端部分と螺合する雌ネジ部を上記円筒部材の内側に設けたものや，加えて，上記円筒部材の内面で前記雌ネジ部と前記円筒部材の開口部との間に，円筒部材の周方向に複数個配置されたリーフスプリングを設けたものが提案されている。この同軸プラグの接続は，円筒部材の先端開口をＦ型レセプタクルに係合させて，雄ネジ部の先端が円筒部材内面に形成された雌ネジ部に接触するまで押し込み，その後は円筒部材を回転させて雌ネジ部をＦ型レセプタクルの雄ネジに螺合させる。そして，円筒部材の外面には操作手段としてセレーションが形成されており，Ｆ型レセプタクルへの接続時の円筒部材の回転を容易にしている。
ところで，接続対象のＦ型レセプタクルには，分配器や分岐器に良く見られるようにハウジングから外方に突設した突出型のものや，テレビ端子のように，パネルに形成された凹部内にその底面中央よりＦ型レセプタクルが突設した非突出型のものがあり，特に後者は，Ｆ型レセプタクル周囲の凹部が狭いため，前記操作手段が該凹部に一部を重合するような位置にあっては，最後まで締付けることが難しくなり操作手段としての役割をなしえない。このため，操作手段は同軸ケーブルコネクタの後方側に備えさせ，テレビ端子に容易に接続できるように構成されているのが一般的であった。

Conventionally, in a coaxial plug that is attached to the end of a coaxial cable and has a contact pin arranged at the center of a cylindrical member, it is screwed with the tip of a male screw formed on the outer peripheral surface of an F-type receptacle to be connected. A plurality of female screw portions are provided inside the cylindrical member, and in addition, a plurality of female screw portions are arranged on the inner surface of the cylindrical member between the female screw portion and the opening of the cylindrical member in the circumferential direction of the cylindrical member. The one provided with a leaf spring has been proposed. The coaxial plug is connected by engaging the tip opening of the cylindrical member with the F-type receptacle and pushing the male screw until the tip of the male screw comes into contact with the female screw formed on the inner surface of the cylindrical member. Then, the female screw portion is screwed into the male screw of the F-type receptacle. Further, serrations are formed as operation means on the outer surface of the cylindrical member, facilitating the rotation of the cylindrical member when connected to the F-type receptacle.
By the way, the F-type receptacle to be connected is a protruding type projecting outward from the housing, as is often seen in distributors and branching devices, and a recess formed in the panel, such as a TV terminal. There is a non-protruding type in which an F-type receptacle projects from the center of the bottom, and in particular, the latter has a narrow recess around the F-type receptacle, so that the operating means is in a position where a part of the recess overlaps the recess. Therefore, it is difficult to tighten until the end, and it cannot serve as an operation means. For this reason, the operation means is generally provided on the rear side of the coaxial cable connector so that it can be easily connected to the television terminal.

Here, details of the connector main body 20 in the first embodiment of the present invention will be described. As well shown in FIG. 2, in the embodiment of the present invention, the connector body 20 is formed by processing a conductive material such as a metal material, and is inserted between the inner insulator 32 and the braid 33 of the coaxial cable 3 at the rear. A cylindrical insertion portion 21 for electrically connecting the connector body 20 and the braid 33, and a cylindrical portion 25 having a larger diameter than the cylindrical insertion portion provided in front of the cylindrical insertion portion 21. It is composed of The cylindrical portion 25 is formed integrally with the cylindrical insertion portion 21 via a step portion 22 and is formed separately from the cylindrical connection body 23, and the cylindrical connection body 23 is formed of a cylindrical fixing body 24 fixed to the front side of 23.
The cylindrical connecting body 23 includes protrusions 23 a and 23 b on the outer periphery thereof, and a cylindrical space 223 having an opening at the front is formed on the inner surface thereof. The space 223 and the inside of the cylindrical insertion portion 21 are formed. The insertion hole 201 for inserting the inner insulator 32 of the coaxial cable 3 formed in the above is continuously provided on the same axis.
The cylindrical fastening body 24 is formed in an outer shape in which the rear side is fixed to the internal space 223 of the cylindrical connecting body 23 by press-fitting and fixing, and the front end is slightly more than the press-fitted portion. A flange 24a having a large diameter is formed. A holding body insertion hole 202 for inserting the holding body 26 for holding the contact pin 8 from the rear side to the front side of the cylindrical fixing body 24 is cylindrical inside the cylindrical fixing body 24. It is formed so as to be concentric with the fastening body 24. At the right end of the holding body insertion hole 202, a holding body fastening piece 203 is formed at the central portion to form an insertion hole having a slightly smaller diameter than the holding body insertion hole 202 on the same axis as the holding body insertion hole 202. The holding body 26 inserted through the holding body insertion hole 202 is prevented from protruding forward.

保持体２６は，例えば合成樹脂などの絶縁性を有する材料から形成されたものであり，コンタクトピン８とコネクタ本体２０の円筒状部２５とを同心位置に配置すると共に，それらの間を絶縁するためのものであり，例えば上述のように円柱状の合成樹脂材にコンタクトピン挿通孔を形成した一体構造で形成されている。
即ち，本発明の実施形態におけるコネクタ本体２０は次のように組み付けられる。先ず，円筒状止着体２４の内部に形成された保持体挿通孔２０２の後方開口端からコンタクトピン保持体２６を装着する。このとき円筒状止着体２４には，後に詳述する接続筒５０を予め挿着しておく。次に，円筒状止着体２４の後方側を前記円筒状接続体２３に圧入固着して組み付けが完了する。
この状態で，円筒状接続体２３の右端と円筒状止着体２４に形成された鍔部２４ａの後方側側面との間には環状溝部２３ｃが形成され，前記接続筒５０は該環状溝部２３ｃにおいて枢着されるように構成されている。
The holding body 26 is formed of an insulating material such as a synthetic resin, for example, and the contact pin 8 and the cylindrical portion 25 of the connector main body 20 are arranged in a concentric position and insulated between them. For example, as described above, it is formed in an integral structure in which contact pin insertion holes are formed in a cylindrical synthetic resin material.
That is, the connector main body 20 in the embodiment of the present invention is assembled as follows. First, the contact pin holder 26 is mounted from the rear opening end of the holder insertion hole 202 formed in the cylindrical fixing body 24. At this time, a connecting cylinder 50, which will be described in detail later, is inserted into the cylindrical fastening body 24 in advance. Next, the rear side of the cylindrical fixing body 24 is press-fitted and fixed to the cylindrical connecting body 23 to complete the assembly.
In this state, an annular groove 23c is formed between the right end of the cylindrical connecting body 23 and the rear side surface of the flange 24a formed on the cylindrical fastening body 24, and the connecting cylinder 50 is connected to the annular groove 23c. It is configured to be pivotally attached.

このように構成されたコネクタ本体２０には，コンタクトピン８が固着された同軸ケーブル３の右端が取付けられる。先ず，コンタクトピン８が，前記コネクタ本体２０に備えられた保持体２６の中心の軸線方向に形成されたコンタクトピン挿通孔２０４に挿入されるように，コネクタ本体２０を差込んでいく。更に差し込みを続けていくとコネクタ本体２０の後方に備えた前記円筒状挿入部２１が同軸ケーブル３の内部絶縁体３２と編組３３との間に差し込まれ，コネクタ本体２０と編組３３とは電気的に接続された状態となるのである。この接続時において同軸ケーブル３の外部被覆３４や編組３３の図における右端部が，円筒状挿入部２１と，該円筒状挿入部２１の前方に位置する前記円筒状接続部２３との間に形成される段部２２の後方側面２２ａに当接するまで差込装着される。従って，同軸ケーブルの加工は，同軸ケーブル３の外部被覆３４や編組３３の図における右端部が，前記段部２２の後方側面２２ａに当接した時に，内部絶縁体３２の右端が，前記段部２２の前方側面２２ｂ（空間２２３の内部後方端）がなす平面と同じ位置になるか，該平面より僅かに後方位置となるように，中心導体３１の露出寸法を決めればよい。
The right end of the coaxial cable 3 to which the contact pin 8 is fixed is attached to the connector body 20 configured in this way. First, the connector body 20 is inserted so that the contact pins 8 are inserted into the contact pin insertion holes 204 formed in the axial direction of the center of the holding body 26 provided in the connector body 20. When the insertion is further continued, the cylindrical insertion portion 21 provided at the rear of the connector body 20 is inserted between the inner insulator 32 and the braid 33 of the coaxial cable 3, and the connector body 20 and the braid 33 are electrically connected. It will be in the state connected to. At the time of this connection, the right end in the figure of the outer sheath 34 and the braid 33 of the coaxial cable 3 is formed between the cylindrical insertion portion 21 and the cylindrical connection portion 23 located in front of the cylindrical insertion portion 21. It is inserted and mounted until it abuts on the rear side surface 22a of the stepped portion 22. Therefore, when processing the coaxial cable, when the right end in the figure of the outer covering 34 and the braid 33 of the coaxial cable 3 is in contact with the rear side surface 22a of the step portion 22, the right end of the internal insulator 32 is moved to the step portion. The exposed dimension of the center conductor 31 may be determined so that it is at the same position as the plane formed by the front side surface 22b of 22 (the inner rear end of the space 223) or slightly behind the plane.

また，コンタクトピン８は前方側に対して，後方側を僅かに大径となるように構成すると共に，このコンタクトピン８を挿通するコンタクトピン挿通孔２０４の右端側を前記コンタクトピン８の前方側が挿通する程度の径の挿通孔２０５とすれば，同軸ケーブル３とコネクタ本体２０との接続完了時において，コンタクトピン８の径が異なることによって生じる段部と，コネクタピン挿通孔２０５とが形成する段部とが嵌合することになり，コネクタピン８の引く抜け方向にたいする力に対して動きを制限できるようになる。
また，図には示されていないが，前記挿通孔２０１の前方側に，内部絶縁体３２の径より僅かに小さく，前記コンタクトピン８の挿通が容易であって，該コンタクトピン８と適宜に離隔を有するように形成された挿通孔を備える止着部を備えることによって，コネクタ本体２０を同軸ケーブルに差込装着したときに，内部絶縁体３２の右端が前記止着部に当接するように構成してもよい。
The contact pin 8 is configured to have a slightly larger diameter on the rear side with respect to the front side, and the right end side of the contact pin insertion hole 204 through which the contact pin 8 is inserted is connected to the front side of the contact pin 8. If the insertion hole 205 has a diameter enough to be inserted, when the connection between the coaxial cable 3 and the connector main body 20 is completed, a step portion generated by the difference in the diameter of the contact pin 8 and the connector pin insertion hole 205 are formed. The step portion is fitted, and the movement can be restricted against the force in the pulling direction of the connector pin 8.
Although not shown in the figure, the diameter of the internal insulator 32 is slightly smaller than the diameter of the internal insulator 32 on the front side of the insertion hole 201, and the contact pin 8 can be easily inserted. By providing a fastening portion having an insertion hole formed so as to have a separation, the right end of the internal insulator 32 comes into contact with the fastening portion when the connector body 20 is inserted into the coaxial cable. It may be configured.

このようにしてコネクタ本体２０と同軸ケーブル３との接続が確実にできたならば，予め同軸ケーブル３を挿通しておいた固定リング５を，円筒状挿入部２１が位置する同軸ケーブル３の外周からカシメ固着することによって機械的にも強固に接続される。この固定リングは金属材料からなるリング状に形成されたカシメ具であり，簡単な構成のカシメ用冶具などを使っての固着を実現できる。
尚，本発明の実施形態における同軸ケーブルの加工方法はこの実施例に限定されるものではなく，編組３３を折り返して接続してもよいなど強固に接続できればその加工方法は問わない。また，外部導体としての編組３３に加えてアルミ箔を備えた同軸ケーブルであっても良いし，編組が二重になった同軸ケーブルでもよくその種類は問わない。
また，前記円筒状挿入部２１の外周に，同軸ケーブル３の内部絶縁体３２と編組３３との間に差し込み易くすると共に，同軸ケーブル３の引き抜け方向の力に対して抜け難いようにするための突起部２１ａを備えることによって，同軸ケーブルの引く抜け方向に対して信頼性を高くすることができる。この突起部２１ａは少なくとも円筒状挿入部２１の先端にあればよく，適宜な間隔を置いて円筒状挿入部の外周面に複数箇所に設けてもよい。
また，同軸ケーブル３の中心導体３１の先端部にコンタクトピン８を接続した構成例を示したが，コネクタピン８の替わりに中心導体３１の露出寸法を長くして使用しても良い。またこの場合は，保持体２６を使ってもよいが，保持体２６の替わりに内部絶縁体３２を使用してもよい。
If the connection between the connector main body 20 and the coaxial cable 3 can be made in this way, the fixing ring 5 through which the coaxial cable 3 has been inserted in advance is connected to the outer periphery of the coaxial cable 3 where the cylindrical insertion portion 21 is located. It is mechanically and firmly connected by caulking and fixing. This fixing ring is a caulking tool formed in a ring shape made of a metal material, and can be fixed using a caulking jig having a simple structure.
In addition, the processing method of the coaxial cable in the embodiment of the present invention is not limited to this example, and the processing method is not limited as long as the braid 33 may be folded and connected. Moreover, in addition to the braid 33 as an external conductor, a coaxial cable provided with an aluminum foil may be used, or a coaxial cable having a double braid may be used.
Further, in order to make it easy to insert the outer periphery of the cylindrical insertion portion 21 between the inner insulator 32 and the braid 33 of the coaxial cable 3 and to prevent the coaxial cable 3 from being pulled out with respect to the force in the pull-out direction. By providing the protruding portion 21a, the reliability can be increased in the pulling direction of the coaxial cable. The protrusions 21a need only be at least at the tip of the cylindrical insertion portion 21, and may be provided at a plurality of locations on the outer peripheral surface of the cylindrical insertion portion with appropriate intervals.
In addition, although the configuration example in which the contact pin 8 is connected to the tip of the central conductor 31 of the coaxial cable 3 is shown, the exposed dimension of the central conductor 31 may be increased instead of the connector pin 8. In this case, the holding body 26 may be used, but the internal insulator 32 may be used instead of the holding body 26.

尚，上記組付け例は，保持体２６が一体構造からなる例を示したが，保持体２６が上下方向（長手方向に開口部を有する）に２分割した物を組み合せる構造としてもよい。即ち，コネクタピン８の中間部に，図には示されていない鍔部を形成し，該鍔部を挟み込むようにして分割形成した保持体を組み付けることで，該鍔部が保持体２６の内部において係止され，これによってコネクタピン８の前後方向への移動が制限され，引き抜け方向の力にも，押圧力にも強い高耐久性にすることができる。この場合のコネクタ本体２０と同軸ケーブル３の組付けは，コンタクトピン８が固着された同軸ケーブル３を円筒状挿入部２１，円筒状接続体２３に組付けた後に，円筒状接続体２３の前方側から，上保持体と下保持体でコンタクトピン８を挟み込むように組付ける。そして，保持体の組み付けが完了したなら円筒状止着体２４を円筒状接続体２３に圧入固着することによって完了する。
In the above assembly example, the holding body 26 has an integral structure. However, the holding body 26 may have a structure in which a vertically divided body (having an opening in the longitudinal direction) is combined. That is, a flange portion (not shown) is formed in the middle portion of the connector pin 8 and the holder is divided and assembled so as to sandwich the flange portion, so that the flange portion is attached to the inside of the holder 26. Accordingly, the movement of the connector pin 8 in the front-rear direction is limited, and high durability that is strong against the force in the pull-out direction and the pressing force can be achieved. In this case, the connector main body 20 and the coaxial cable 3 are assembled by assembling the coaxial cable 3 to which the contact pins 8 are fixed to the cylindrical insertion portion 21 and the cylindrical connecting body 23 and then to the front of the cylindrical connecting body 23. Assemble from the side so that the contact pin 8 is sandwiched between the upper holder and the lower holder. When the assembly of the holding body is completed, the cylindrical fastening body 24 is completed by press-fitting and fixing to the cylindrical connecting body 23.

このようにコネクタ本体２０と同軸ケーブル３との組付けが完了したのならば，この接続部を被うように同軸ケーブルカバー１０が取付けられる。本発明の実施形態ではこの同軸ケーブルカバー１０は同軸ケーブル３の右端部と，円筒状挿入部２１と，円筒状接続部２３の外周面に形成された突条体２３を被うように構成されている。
図３に良く示されるように，この同軸ケーブルカバー１０は，全体形状が略円形状に形成された合成樹脂材を成形したものである。そしてその前方においては固定形状であり，その内部における係止溝部１３ａと段差部１３ｂとが夫々円筒状接続部２３の外周に形成された前記突条体２３ａ，２３ｂと嵌合している。即ち，突条体２３ａと係止溝部１３ａとの嵌合によって引き抜け方向（左方向の力）に対して，突条体２３ｂと段差１３ｂとの嵌合によって押し込み方向（右方向の力）に対して，夫々動きを制限して同軸ケーブルカバーが確実に固着されるように構成されている。
また同軸ケーブルカバー１０の後方においては屈曲性を持たせた蛇腹状の屈曲部１１が形成されおり，同軸ケーブル３が屈曲する力を吸収して接続部を保護している。尚，本発明の実施例における同軸ケーブルカバーは，合成樹脂材を前記接続部にモールド加工若しくは嵌め込みによって固着している。
When the assembly of the connector main body 20 and the coaxial cable 3 is completed in this way, the coaxial cable cover 10 is attached so as to cover this connecting portion. In the embodiment of the present invention, the coaxial cable cover 10 is configured to cover the right end portion of the coaxial cable 3, the cylindrical insertion portion 21, and the protrusions 23 formed on the outer peripheral surface of the cylindrical connection portion 23. ing.
As shown well in FIG. 3, the coaxial cable cover 10 is formed by molding a synthetic resin material whose overall shape is substantially circular. And in the front, it is a fixed shape and the engaging groove part 13a and the level | step-difference part 13b in the inside are fitting with the said protrusions 23a and 23b formed in the outer periphery of the cylindrical connection part 23, respectively. That is, in the pulling-out direction (leftward force) due to the fitting between the protruding body 23a and the locking groove 13a, in the pushing direction (rightward force) due to the fitting between the protruding body 23b and the step 13b. On the other hand, the coaxial cable cover is securely fixed by restricting the movement.
Further, a bellows-like bent portion 11 having flexibility is formed behind the coaxial cable cover 10, and the connecting portion is protected by absorbing the bending force of the coaxial cable 3. In the coaxial cable cover according to the embodiment of the present invention, a synthetic resin material is fixed to the connecting portion by molding or fitting.

次に，接続筒５０について詳細に説明する。図４によく示されるように本発明における接続筒５０は，前記コネクタ本体２０の円筒状部２５の外周に，円周方向に回動可能に枢着するように取付けられる円筒状基部５１と，該円筒状基部５１の前方側に延長させ，内周に接続対象のＦ型レセプタクルが挿入されるための拡開性を持つ円筒状受け口部５５とから構成された金属材料などの導電材を加工したものである。
前記円筒状基部５１の内面には軸心方向に突設した凸部５３が形成されており，該凸部５３が，前記円筒状止着体２４の後方側を前記円筒状接続体２３に圧入固着したときに形成される環状溝部２３ｃに嵌め込まれ，円筒状基部５１（即ち，接続筒５０）は円筒状部２５に回転自在に枢着される。即ち，接続筒５０の円筒状受け口部５５側から前記円筒状止着体２４を挿通し，その後に，該円筒状止着体２４を前記円筒状接続体２３に圧入する事によって組み立てが完了し抜け落ちることはない。
尚，図４における５２は円筒状基部５１の外周に形成されたローレットであり，５１ａ，５１ｂは円筒状基部５１の外周であって相対向する位置に形成された所定の大きさからなる一対の平面部であり，この平面部によって円筒状基部５１に２面幅が形成されている。
Next, the connection cylinder 50 will be described in detail. As shown well in FIG. 4, the connection tube 50 according to the present invention includes a cylindrical base 51 attached to the outer periphery of the cylindrical portion 25 of the connector body 20 so as to be pivotably pivotable in the circumferential direction; Processing a conductive material such as a metal material that extends to the front side of the cylindrical base 51 and has a cylindrical receiving portion 55 having an expandability for inserting an F-type receptacle to be connected to the inner periphery. It is a thing.
A convex portion 53 projecting in the axial direction is formed on the inner surface of the cylindrical base portion 51, and the convex portion 53 press-fits the rear side of the cylindrical fastening body 24 into the cylindrical connecting body 23. The cylindrical base portion 51 (that is, the connecting tube 50) is pivotally attached to the cylindrical portion 25 so as to be fitted into an annular groove portion 23c formed when the members are fixed. That is, the assembly is completed by inserting the cylindrical fastening body 24 from the cylindrical receptacle 55 side of the connection cylinder 50 and then press-fitting the cylindrical fastening body 24 into the cylindrical connection body 23. It will not fall out.
In FIG. 4, 52 is a knurl formed on the outer periphery of the cylindrical base 51, and 51a and 51b are a pair of predetermined sizes formed on the outer periphery of the cylindrical base 51 opposite to each other. It is a plane part, and the two-plane width is formed in the cylindrical base 51 by this plane part.

前記円筒状受け口部５５には，接続対象のＦ型レセプタクルの受入れを容易にすると共にＦ型レセプタクルの外部導体との接続をよくするために，該円筒状受け口部５５の前方端から後方にかけて軸方向に延びる少なくとも１つのすり割り５５ａが形成されている。更に，円筒状受け口部５５の先端部の外周には，リングバネ５６が備えられており，このリングバネ５６の締め付け作用によって円筒状受け口部５５内周とＦ型レセプタクルの外周とがより確実に接続されるように構成されている。
尚，すり割り５５ａに替えて，円筒状受け口部５５の内周に導電性を有した弾性材からなる軸方向に長いリング状のバネを備えさせてもよい。
The cylindrical receptacle 55 has a shaft extending from the front end to the rear of the cylindrical receptacle 55 in order to facilitate the reception of the F-type receptacle to be connected and to improve the connection with the outer conductor of the F-type receptacle. At least one slot 55a extending in the direction is formed. Further, a ring spring 56 is provided on the outer periphery of the distal end portion of the cylindrical receiving portion 55, and the inner periphery of the cylindrical receiving portion 55 and the outer periphery of the F-type receptacle are more reliably connected by the tightening action of the ring spring 56. It is comprised so that.
In place of the slit 55a, a ring-shaped spring made of an elastic material having conductivity may be provided on the inner periphery of the cylindrical receiving portion 55.

更に，円筒状受け口部５５内面の後方部には，接続対象のＦ型レセプタクルの先端部に形成された雄ネジと螺合する雌ネジ部５７が形成されており，例えば本願の実施形態における雌ネジ部５７は，前記Ｆ型レセプタクルの雄ネジの先端部との間において略３回転螺合するようなネジ山数に形成すればよい。尚，本発明の実施形態においては，接続時間を短縮すると共に，引き抜け方向に対する強度を所定値以上となるように目標を定めたことから，略３回転螺合するようなネジ山数に形成したが，特に実施例に限定されるものではなく，３回転の螺合より多くても少なくてもよい。また，雌ネジ部の無い摺動だけによって固着するプッシュオン方式の同軸プラグにしても良いなど，円筒状受け口部の構造は問わない。
Furthermore, a female screw portion 57 that is screwed with a male screw formed at the tip of the F-type receptacle to be connected is formed at the rear portion of the inner surface of the cylindrical receptacle portion 55. For example, the female screw portion 57 in the embodiment of the present application is formed. The threaded portion 57 may be formed in such a number of threads as to be screwed approximately three times between the front end portion of the male thread of the F-type receptacle. In the embodiment of the present invention, since the connection time is shortened and the target is set so that the strength in the pull-out direction is not less than a predetermined value, the number of threads is set so as to be screwed approximately three times. However, the present invention is not particularly limited to the embodiment, and may be more or less than three rotations. Further, the structure of the cylindrical receiving portion is not limited, such as a push-on type coaxial plug that is fixed only by sliding without a female screw portion.

円筒状受け口部５５の奥行は，接続対象であるＦ型レセプタクルの軸方向の寸法が規格値における最小であるレセプタクルに対して螺合した状態で，前記円筒状部２５（言い換えれば，円筒状止着体２４）の右側開口端２７が前記Ｆ型レセプタクルの端面と当接する（即ち，プラグを締付けたときに，円筒状受け口部５５の前端が，Ｆ型レセプタクルが取付けられた台座，例えば，ハウジングやシールドケースなどの壁面に当接しない）ように円筒状受け口部５５の奥行が定められておれば，高周波特性やイミュニティーの優れたものとすることができる。
更に，円筒状受け口部５５に形成された前記すり割り５５ａは，例えば，プラグを接続対象のＦ型レセプタクルに摺動固着した状態で使用する場合を勘案して，円筒状受け口部５５に受入れたＦ型レセプタクルの寸法より僅かに短く形成すれば，すり割りによって生じる隙間がＦ型レセプタクルによって塞がれ，高周波信号が漏れたり，外部からの妨害電波によって影響を受けたりすることがない。
The depth of the cylindrical receptacle 55 is such that the cylindrical portion 25 (in other words, the cylindrical stopper) is engaged with the receptacle having the axial dimension of the F-type receptacle to be connected, which is the smallest in the standard value. The right opening end 27 of the body 24 is in contact with the end surface of the F-type receptacle (that is, when the plug is tightened, the front end of the cylindrical receiving portion 55 is a pedestal to which the F-type receptacle is attached, such as a housing. If the depth of the cylindrical receptacle 55 is determined so that it does not abut against the wall surface of the shield case or the like, the high frequency characteristics and immunity can be improved.
Further, the slit 55a formed in the cylindrical receiving portion 55 is received in the cylindrical receiving portion 55 in consideration of, for example, the case where the plug is used in a state where the plug is slidably fixed to the F-type receptacle to be connected. If it is formed slightly shorter than the size of the F-type receptacle, the gap caused by the slitting is not blocked by the F-type receptacle, so that a high-frequency signal is not leaked or affected by external interference.

そして，円筒状基部５１に，図５に示される該円筒状基部５１の外周面の全て若しくは一部を被うように形成された合成樹脂材からなる円筒状操作手段４１を備えさせることによってＦ型レセプタクルへの接続作業を効率よく行うことができる。
本発明の実施例では，この円筒状操作手段４１は全体形状が略円形筒状で合成樹脂材からなり，前記円筒状基部５１に嵌め込まれたりモールド加工されたりして取付けられる。そして円筒状操作手段４１の外周面には，凸凹４３が適宜に形成されており，その滑り止め効果によって接続作業に容易性を持たせることができる。また，円筒状操作手段４１が弾性のある柔らかな素材で形成されておれば，指先に加わる負担も軽減される。
この円筒状操作手段４１を，図６に示すように円筒状基部５１に取付けた場合は，該円筒状部５１に形成された２面幅の平面部５１ａ，５１ｂに対向する位置に，夫々の平面部５１ａ，５１ｂに対応する形状に形成されて貫通した貫通孔４１ａ，４１ｂを形成し，該貫通孔４１ａ，４１ｂの，少なくとも円筒状操作手段４１の軸線に直交する方向の外周に形成される開口端面４２ａ，４２ｂが，前記平面部５１ａ，５１ｂと略同一平面上若しくは僅かに軸線側となるように構成することによって，円筒状操作手段４１を備えても，円筒状操作手段４１が接続筒５０の締付け性を損なうことがなく，指先での接続もできるし，レンチやスパナのような工具で直接に平面部５１ａ，５１ｂを挟み込んでの機械的な接続もできるのである。
Then, the cylindrical base 51 is provided with a cylindrical operation means 41 made of a synthetic resin material formed so as to cover all or part of the outer peripheral surface of the cylindrical base 51 shown in FIG. The connection work to the mold receptacle can be performed efficiently.
In the embodiment of the present invention, the cylindrical operating means 41 is formed of a synthetic resin material with a generally circular cylindrical shape, and is attached to the cylindrical base 51 by being fitted or molded. Further, irregularities 43 are appropriately formed on the outer peripheral surface of the cylindrical operation means 41, and the connection work can be facilitated by its anti-slip effect. Moreover, if the cylindrical operation means 41 is formed of an elastic soft material, the burden applied to the fingertip is reduced.
When the cylindrical operating means 41 is attached to the cylindrical base 51 as shown in FIG. 6, each of the cylindrical operating means 41 is positioned at a position facing the two-plane width flat portions 51a and 51b formed on the cylindrical portion 51. Through holes 41a and 41b are formed and formed in a shape corresponding to the flat portions 51a and 51b, and are formed on the outer periphery of the through holes 41a and 41b at least in a direction perpendicular to the axis of the cylindrical operation means 41. Even if the cylindrical operation means 41 is provided by configuring the opening end faces 42a and 42b to be substantially on the same plane as the plane portions 51a and 51b or slightly on the axis side, the cylindrical operation means 41 is connected to the connecting cylinder. 50 can be connected with a fingertip without impairing the tightening performance, and can be mechanically connected with a tool such as a wrench or spanner directly sandwiching the flat portions 51a and 51b.

更に，本発明の実施形態においては，円筒状操作手段４１は後方側開口端部の外周径より前方側開口端部の外周径の方を大きくして，円筒状操作手段４１の前方側開口端部の外周面に環状突起４５が備えられている。この環状突起４５の前方端部には，その外周が先細の前方先端部から肉厚を徐々に厚く成るように円錐状に形成された円錐状部４６が形成されており，この同軸ケーブルコネクタを，例えば図７に示されるように接続対象のＦ型レセプタクル８５がテレビ端子８０によく見られる円筒状の凹部８３に埋め込まれた非突出型のものに対して接続した時に，円錐状部４６の外周面４７が凹部８３の開放面周縁と当接するように，該円錐状部４６の前方先端部の外周径４６ａは前記凹部８３の開放面の内周径より小さく，円錐状部４６の後方後端部の外周径４６ｂは前記凹部８３の開放面の内周径と同じか大きくなるように形成されている。
Furthermore, in the embodiment of the present invention, the cylindrical operating means 41 has a larger opening diameter at the front opening end than the outer diameter at the rear opening end, so that the front opening end of the cylindrical operating means 41 is increased. An annular protrusion 45 is provided on the outer peripheral surface of the part. A conical portion 46 formed in a conical shape is formed at the front end portion of the annular protrusion 45 so that the outer periphery of the annular protrusion 45 gradually increases in thickness from the tapered front end portion. For example, as shown in FIG. 7, when the F-type receptacle 85 to be connected is connected to a non-projecting type embedded in a cylindrical recess 83 often found in the TV terminal 80, the conical portion 46 The outer peripheral diameter 46 a of the front end of the conical portion 46 is smaller than the inner peripheral diameter of the open surface of the concave portion 83 so that the outer peripheral surface 47 abuts on the peripheral edge of the open surface of the concave portion 83. The outer peripheral diameter 46b of the end is formed to be the same as or larger than the inner peripheral diameter of the open surface of the recess 83.

即ち，本発明の実施形態に示す同軸ケーブルコネクタの目的の内の一つは，同軸ケーブルコネクタの接続の煩雑さを低減すると共に，それでも引き抜け難い接続ができるようにすることであり，そのため接続方法は，対象のＦ型レセプタクルが雌ネジ部５７に当接するまでは摺動によって挿着し，当接した後はＦ型レセプタクルの先端部に前記雌ネジ部５７を螺合させて接続が完了するように構成されている。従って，接続時には同軸ケーブルコネクタをＦ型レセプタクルに対して押付けるように力を加えながら行えば，その接続作業はスムーズで確実に行うことができる。つまり，前記環状突起４５は円筒状操作手段４１の前方側開口端部の径方向外方に突設されているので，指先を環状突起４５に当て付けることによって接続筒に対して押圧力を加え易くなり，雌ネジ部５７がＦ型レセプタクルにスムーズに螺合することができるのである。具体的には，例えば図７に示されるように接続対象のＦ型レセプタクル８５がテレビ端子８０によく見られる円筒状の凹部８３に埋め込まれた非突出型のものに対して接続する場合，凸凹４３の滑り止め効果と環状突起４５の押圧力の受止作用によって接続が簡単にできる。
そして，接続が完了した状態では，環状突起４５はパネル８２に近接して配設され，パネル８２から突出することが少なくなるのでスッキリと配線できるし，環状突起４５がテレビ端子に対して外方に突出しないので邪魔になることはない。加えて，環状突起４５に形成した円錐状部４６の外周面４７の任意の位置は，凹部８３の開放面周縁と当接して凹部８３を閉塞するので，凹部８３内に埃などが入らないのである。
また，同軸ケーブルコネクタグ２をレセプタクルから引き抜くためには，まず円筒状操作手段４１（即ち，接続筒）を回転操作すればよく，格別に環状突起４５を必要としないが，Ｆ型レセプタクルに対する螺合が解除されれば，パネル８２と環状突起４５との間の間隙が大きくなり，環状突起４５に指を掛け易くなることから，環状突起４５は同軸ケーブルコネクタの引き抜きを容易とする役目もするのである。
尚，環状突起４５は円錐状部４５を備えた例を示したが，特に円錐状部４５は無くてもよく，前記円筒状部２５（言い換えれば，円筒状止着体２４）の右側開口端２７が前この場合，環状突起４５の前方端がパネル８２に近接若しくは当接するように構成することによって凹部８３は閉塞される。
In other words, one of the purposes of the coaxial cable connector shown in the embodiment of the present invention is to reduce the complexity of the connection of the coaxial cable connector and still allow a connection that is difficult to pull out. The method is such that the F-type receptacle is inserted by sliding until the F-type receptacle contacts the female threaded portion 57. After the contact, the female-threaded portion 57 is screwed into the tip of the F-type receptacle to complete the connection. Is configured to do. Accordingly, if the coaxial cable connector is pressed while applying a force so as to press against the F-type receptacle, the connecting operation can be performed smoothly and reliably. That is, since the annular protrusion 45 protrudes radially outward from the front opening end of the cylindrical operation means 41, a pressing force is applied to the connecting tube by applying the fingertip to the annular protrusion 45. Thus, the female screw portion 57 can be smoothly screwed into the F-type receptacle. Specifically, for example, as shown in FIG. 7, when an F-type receptacle 85 to be connected is connected to a non-projecting type embedded in a cylindrical recess 83 often found in the TV terminal 80, The connection can be simplified by the anti-slip effect of 43 and the receiving action of the pressing force of the annular protrusion 45.
When the connection is completed, the annular protrusion 45 is disposed close to the panel 82 and protrudes less from the panel 82 so that it can be wired more clearly. It will not get in the way because it does not protrude. In addition, an arbitrary position of the outer peripheral surface 47 of the conical portion 46 formed on the annular protrusion 45 abuts the periphery of the open surface of the concave portion 83 to close the concave portion 83, so that dust or the like does not enter the concave portion 83. is there.
Further, in order to pull out the coaxial cable connector 2 from the receptacle, the cylindrical operation means 41 (that is, the connecting cylinder) is first rotated, and no special annular protrusion 45 is required, but the screw for the F-type receptacle is not required. When the connection is released, the gap between the panel 82 and the annular protrusion 45 becomes large, and it becomes easy to put a finger on the annular protrusion 45. Therefore, the annular protrusion 45 also serves to facilitate the pull-out of the coaxial cable connector. It is.
In addition, although the annular protrusion 45 showed the example provided with the cone-shaped part 45, the cone-shaped part 45 may not be in particular, and the right side opening end of the said cylindrical part 25 (in other words, cylindrical fixing body 24). In this case, the concave portion 83 is closed by configuring the front end of the annular protrusion 45 to be close to or in contact with the panel 82.

尚，図１０に示されるように，前記円筒状部２５（言い換えれば，円筒状止着体２４）の右側開口端２７と前記雌ネジ部５７との間に間隙を形成し，該間隙には円筒状受け口部５５に内接するように形成された導電性を有する弾性部材からなるリング状の緩衝部材５８を備えさせてもよい。即ち，雌ネジ部５７がＦ型レセプタクルの雄ネジに完全に螺合する前に，前記円錐状部４６の外周面４７が凹部の開放面周縁に当接してしまって，円筒状部２５の右側開口端２７とＦ型レセプタクルの先端が接続しなくても，緩衝部材５８が介在されたことによって接続筒５０とＦ型レセプタクルの外部導体との電気的接続を良好に保つことができる。また，雌ネジ部５７がＦ型レセプタクルの雄ネジに完全に螺合しても，前記円錐状部４６の外周面４７が凹部の開放面周縁に当接しない場合でも，更に接続筒を締付けることによって緩衝部材が弾性変形し，前記円錐状部４６の外周面４７が凹部の開放面周縁に当接若しくは近接させることができる。
As shown in FIG. 10, a gap is formed between the right opening end 27 of the cylindrical portion 25 (in other words, the cylindrical fastening body 24) and the female screw portion 57. You may provide the ring-shaped buffer member 58 which consists of an elastic member which has the electroconductivity formed so that the cylindrical receptacle part 55 might be inscribed. That is, before the female screw portion 57 is completely screwed into the male screw of the F-type receptacle, the outer peripheral surface 47 of the conical portion 46 comes into contact with the periphery of the open surface of the concave portion, and the right side of the cylindrical portion 25 is Even if the opening end 27 and the tip of the F-type receptacle are not connected to each other, the electrical connection between the connection tube 50 and the outer conductor of the F-type receptacle can be kept good by the interposition of the buffer member 58. Further, even if the female screw portion 57 is completely screwed into the male screw of the F-type receptacle, the connecting cylinder is further tightened even if the outer peripheral surface 47 of the conical portion 46 does not contact the peripheral edge of the open surface of the recess. Thus, the buffer member is elastically deformed, and the outer peripheral surface 47 of the conical portion 46 can be brought into contact with or close to the periphery of the open surface of the recess.

以上，本発明の同軸ケーブルコネクタは，近年普及が著しい大型の液晶テレビと，テレビが設置されたテレビ台等の背後にあるテレビ端子とを接続するような，テレビ台等を動かさずには設置や取り外しが難しい場所に用いても，指先や工具を使って強固に接続することができるので，長年にわたって良好な接続状態を維持することができるのである。
また，上述のようにテレビやテレビ台の背後等のような，埃などが溜まり易い場所に設置されたテレビ端子は掃除もやり難く，その上，テレビ端子のパネルに形成された凹部が狭くて，一度入った埃を取り出すことが難しいのであるが，本発発明の同軸ケーブルコネクタを用いれば，操作手段に形成された環状突起によって，コネクタとパネルの開放面の間に形成される間隙が閉塞若しくは僅かな間隙となって，凹部内に埃が入ってしまう事が無くなるのである。
また，パソコンや液晶テレビを自在に持ち運んで，机や寝室のベッド，キッチンなどの近傍にあるテレビ端子を用いてテレビを見る場合であっても，テレビやノートパソコンとテレビ端子とを接続するケーブルに本発明のコネクタを用いることによって，接続作業が簡単で且つ確実にできる。また，環状突起をテレビ端子に備えられたパネルにマッチしたデザインにする事によって，見栄えのよいスッキリとした配線ができるのである。

尚，本発明は同軸ケーブルコネクタについての説明であるが，同軸ケーブル付きであってもよいなど，上記実施の形態に限定されるものではなく，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。
