In the direction, at least the plug member 2 of the F-type plug 1 is rotated relative to the male screw portion B1 of the F-type connector B.

この結果、Ｆ型コネクタＢの雄ねじ部Ｂ１がＦ型プラグ１のプラグ部材２の開口部２ａ内に抜け止め保持された状態となり、このＦ型プラグ１を介してＦ型コネクタＢに同軸ケーブルＡが接続される。 As a result, the male threaded portion B1 of the F-type connector B is held in the opening 2a of the plug member 2 of the F-type plug 1, and the coaxial cable A is connected to the F-type connector B via the F-type plug 1. Is connected.

＜作用効果＞
前述のように、Ｆ型プラグ１のプラグ部材２の内周面に、このプラグ部材２の軸方向において、Ｆ型コネクタＢの雄ねじ部Ｂ１のねじ溝Ｂ２のピッチＢ３の整数倍、例えば１ピッチほどの間隔を空けた位置に複数のボッチ２ｅを設けている。そして、このプラグ部材２の開口部２ａを、Ｆ型コネクタＢの雄ねじ部Ｂ１の外径寸法より若干大きな内径寸法とし、このプラグ部材２の各ボッチ２ｅを、雄ねじ部Ｂ１のねじ溝の高さ寸法より若干小さな高さ寸法としている。 <Effect>
As described above, an integral multiple of the pitch B3 of the thread groove B2 of the male threaded portion B1 of the F-type connector B in the axial direction of the plug member 2 on the inner peripheral surface of the plug member 2 of the F-type plug 1, for example, 1 pitch A plurality of botches 2e are provided at positions spaced at a certain interval. Then, the opening 2a of the plug member 2 has an inner diameter that is slightly larger than the outer diameter of the male thread B1 of the F-type connector B, and each of the bosses 2e of the plug member 2 has a height of the thread groove of the male thread B1. The height is slightly smaller than the dimensions.

この結果、Ｆ型プラグ１のプラグ部材２の開口部２ａにＦ型コネクタＢの雄ねじ部Ｂ１を嵌合させた際に、このＦ型プラグ１のプラグ部材２に設けた各ボッチ２ｅがＦ型コネクタＢの雄ねじ部Ｂ１のねじ溝Ｂ２に所定のピッチ間隔を空けた位置に係止する。したがって、Ｆ型プラグ１の開口部２ａに嵌合させたＦ型コネクタＢの雄ねじ部Ｂ１を各ボッチ２ｅにて立体的に係止することができるから、Ｆ型コネクタＢの雄ねじ部Ｂ１をＦ型プラグ１の開口部２ｅに確実に抜け止め保持することができる。 As a result, when the male threaded portion B1 of the F-type connector B is fitted into the opening 2a of the plug member 2 of the F-type plug 1, each of the botches 2e provided on the plug member 2 of the F-type plug 1 becomes the F-type. The connector B is locked at a position with a predetermined pitch interval in the thread groove B2 of the male thread B1 of the connector B. Therefore, since the male threaded portion B1 of the F-type connector B fitted into the opening 2a of the F-shaped plug 1 can be three-dimensionally locked by the respective botches 2e, the male threaded portion B1 of the F-shaped connector B is The mold plug 1 can be securely held in the opening 2e of the mold plug 1.

さらに、Ｆ型プラグ１のプラグ部材２の一端寄りの各ボッチ２ｅが、Ｆ型コネクタＢの雄ねじ部Ｂ１のねじ溝Ｂ２の端部に当接するまで、Ｆ型コネクタＢの雄ねじ部Ｂ１をＦ型プラグ１の開口部２ｅに挿入させる。この後、Ｆ型コネクタＢの雄ねじ部Ｂ１がＦ型プラグ１のスリーブ部材５の接続片部５ｂに当接する位置まで、Ｆ型プラグ１の少なくともプラグ部材２を、Ｆ型コネクタＢの雄ねじ部Ｂに対して相対的に回転させることによって、Ｆ型プラグ１の開口部２ｅにＦ型コネクタＢの雄ねじ部Ｂ１を取り付けることができる。以上から、取り付けが容易なワンタッチ式であって、Ｆ型コネクタＢの雄ねじ部Ｂ１の嵌合を確実に抜け止め保持することができるＦ型プラグ１を実現することができる。 Further, the male threaded portion B1 of the F-type connector B is moved to the F-type until each of the botches 2e near the one end of the plug member 2 of the F-shaped plug 1 comes into contact with the end of the thread groove B2 of the male threaded portion B1 of the F-shaped connector B. Insert into the opening 2 e of the plug 1. Thereafter, at least the plug member 2 of the F-type plug 1 is moved to the male screw portion B of the F-type connector B until the male screw portion B1 of the F-type connector B comes into contact with the connection piece 5b of the sleeve member 5 of the F-type plug 1. The male threaded portion B1 of the F-type connector B can be attached to the opening 2e of the F-type plug 1 by rotating it relatively. From the above, it is possible to realize the F-type plug 1 that is a one-touch type that can be easily attached and that can securely hold and retain the fitting of the male threaded portion B1 of the F-type connector B.

またさらに、Ｆ型プラグ１の開口部２ａにＦ型コネクタＢの雄ねじ部Ｂ１を嵌合させた際に、この雄ねじ部Ｂ１のねじ溝Ｂ２の先端寄りの位置に係合するように、Ｆ型プラグ１のプラグ部材２の他端寄りの位置に各ボッチ２ｅを設けた構成としている。このため、Ｆ型プラグ１の開口部２ａにＦ型コネクタＢの雄ねじ部Ｂ１を嵌合させた際に、この雄ねじ部Ｂ１のねじ溝Ｂ２の先端寄りの位置に各ボッチ２ｅが係合することとなる。 Further, when the male threaded portion B1 of the F-shaped connector B is fitted into the opening 2a of the F-shaped plug 1, the F-shaped so as to engage with the position near the tip of the thread groove B2 of the male threaded portion B1. Each button 2e is provided at a position near the other end of the plug member 2 of the plug 1. For this reason, when the male threaded portion B1 of the F-type connector B is fitted into the opening 2a of the F-shaped plug 1, each of the botches 2e is engaged at a position near the tip of the thread groove B2 of the male threaded portion B1. It becomes.

したがって、Ｆ型プラグ１のプラグ部材２の一端寄りの位置に各ボッチ２ｅを設け、これらボッチ２ｅをＦ型コネクタＢの雄ねじ部Ｂ１のねじ溝Ｂ２の基端寄りの位置に係合させるようにした場合に比べ、Ｆ型プラグ１のプラグ部材２の一端寄りの各ボッチ２ｅが、Ｆ型コネクタＢの雄ねじ部Ｂ１のねじ溝Ｂ２の端部に当接するまで、この雄ねじ部Ｂ１をＦ型プラグ１の開口部２ｅに挿入させた後、この雄ねじ部Ｂ１がＦ型プラグ１のスリーブ部材５の接続片部５ｂに当接する位置まで、この雄ねじ部Ｂ１に対してＦ型プラグ１を回転させる際の回転量を少なくすることができる。 Accordingly, each of the botches 2e is provided at a position near one end of the plug member 2 of the F-type plug 1, and these botches 2e are engaged with positions near the base end of the thread groove B2 of the male threaded portion B1 of the F-type connector B. Compared to the case, the male threaded portion B1 is inserted into the F-type plug until each of the botches 2e near the one end of the plug member 2 of the F-shaped plug 1 comes into contact with the end of the thread groove B2 of the male threaded portion B1 of the F-type connector B. When the F-type plug 1 is rotated with respect to the male screw portion B1 until the male screw portion B1 comes into contact with the connecting piece 5b of the sleeve member 5 of the F-type plug 1 after being inserted into the opening portion 2e of the F-type plug 1. The amount of rotation can be reduced.

よって、Ｆ型プラグ１に対するＦ型コネクタ１の嵌合を確実に抜け止め保持させる際の、Ｆ型プラグ１の回転量を少なくでき、Ｆ型コネクタＢの雄ねじ部Ｂ１にＦ型プラグ１を取り付ける際の回転作業をより簡略化することができるから、より取り付けが容易なワンタッチ式のＦ型プラグ１となる。 Therefore, the amount of rotation of the F-type plug 1 can be reduced when the F-type connector 1 is securely fitted and held in the F-type plug 1, and the F-type plug 1 is attached to the male thread B1 of the F-type connector B. Therefore, the one-touch F-type plug 1 can be more easily installed.

特に、Ｆ型プラグ１を構成するプラグ部材２、スリーブ部材５、およびかしめリング６のそれぞれにつき、周面にねじ溝等を形成する必要がないため、切削成形のみならず、プレス成形やダイカスト成形等でも、Ｆ型プラグ１を形成することができる。 In particular, since it is not necessary to form a thread groove or the like on the peripheral surface of each of the plug member 2, the sleeve member 5 and the caulking ring 6 constituting the F-type plug 1, not only cutting molding but also press molding or die casting molding. Etc., the F-type plug 1 can be formed.

Next, an F-type plug 1A according to a second embodiment of the present invention will be described with reference to FIGS. FIG. 4 is a perspective view from the front side of an F-type plug 1A according to the second embodiment of the present invention. FIG. 5 is a perspective view in which a part of the F-type plug 1A shown in FIG. 4 is cut away.

本第２実施形態に係るＦ型プラグ１Ａは、図４および図５に示すように、上記第１実施形態に係るＦ型プラグ１において、プラグ部材２の開口部２ａに設けたボッチ２ｅを、Ｆ型コネクタＢの雄ねじ部Ｂ１のピッチＢ３に対応させた円弧状の係止リブ７とした構成としている。なお、本第２実施形態において、上記第１実施形態と同一の構成および作用については、その説明を省略している。 As shown in FIGS. 4 and 5, the F-type plug 1 </ b> A according to the second embodiment includes a bottom 2 e provided in the opening 2 a of the plug member 2 in the F-type plug 1 according to the first embodiment. An arcuate locking rib 7 corresponding to the pitch B3 of the male threaded portion B1 of the F-type connector B is used. In the second embodiment, the description of the same configuration and operation as those in the first embodiment is omitted.

係止リブ７は、開口部２ａの周方向に向けて、この開口部２ａの約１周に亘った螺旋状の係止部である。すなわち、係止リブ７は、Ｆ型コネクタＢの雄ねじ部Ｂ１の１ピッチ分に亘って形成されている。また、係止リブ７は、プラグ部材２の開口部２ａを外周側から内径方向にプレスして断面凸弧状に形成されている。 The locking rib 7 is a spiral locking portion that extends over the entire circumference of the opening 2a in the circumferential direction of the opening 2a. That is, the locking rib 7 is formed over one pitch of the male screw portion B1 of the F-type connector B. The locking rib 7 is formed in a convex arc shape by pressing the opening 2a of the plug member 2 in the inner diameter direction from the outer peripheral side.

よって、Ｆ型プラグ１Ａは、係止リブ７がＦ型コネクタＢの雄ねじ部Ｂ１のねじ溝Ｂ２の端部に当接するまで、この雄ねじ部Ｂ１を開口部２ａに挿入してから、プラグ部材２をＦ型コネクタＢの雄ねじ部Ｂ１に対して相対的に回転させて、係止リブ７をＦ型コネクタＢの雄ねじ部Ｂ１に係合させることにより、Ｆ型コネクタＢの雄ねじ部Ｂ１を開口部２ａ内に抜け止め保持させることができる。 Therefore, the F-type plug 1A is inserted into the opening 2a until the locking rib 7 comes into contact with the end of the screw groove B2 of the male screw B1 of the F-type connector B, and then the plug member 2 is inserted. Is rotated relative to the male screw portion B1 of the F-type connector B, and the engaging rib 7 is engaged with the male screw portion B1 of the F-type connector B, whereby the male screw portion B1 of the F-type connector B is opened. It is possible to hold it within 2a.

特に、プラグ部材２の係止リブ７を、Ｆ型コネクタＢの雄ねじ部Ｂ１の１ピッチ分の長さの螺旋状としている。このため、係止リブ７をＦ型コネクタＢの雄ねじ部Ｂ１のねじ溝Ｂ２に係合させた場合に、この雄ねじ部Ｂ１の１ピッチ分のねじ溝Ｂ２に亘って係止リブ７が係合することとなり、この雄ねじ部Ｂ１のねじ溝Ｂ２との接触面積を広くすることができる。よって、上記第１実施形態に係るＦ型プラグ１のボッチ２ｅに比べ、Ｆ型コネクタＢの雄ねじ部Ｂ１を開口部２ａ内に係止させた場合の抜け止め保持をより確実にできる。 In particular, the locking rib 7 of the plug member 2 has a spiral shape with a length corresponding to one pitch of the male screw portion B1 of the F-type connector B. For this reason, when the locking rib 7 is engaged with the thread groove B2 of the male threaded portion B1 of the F-type connector B, the locking rib 7 is engaged over the thread groove B2 of one pitch of the male threaded portion B1. As a result, the contact area between the male thread B1 and the thread groove B2 can be increased. Therefore, it is possible to more reliably retain the retainer when the male threaded portion B1 of the F-type connector B is locked in the opening 2a, as compared with the bottom 2e of the F-type plug 1 according to the first embodiment.

［第３実施形態］
次に、本考案の第３実施形態に係るＦ型プラグ１Ｂについて、図６および図７を参照して説明する。図６は、本考案の第３実施形態に係るＦ型プラグ１Ｂの正面側からの斜視図である。図７は、図６に示すＦ型プラグ１Ｂの一部を切り欠いた斜視図である。 [Third Embodiment]

FIG. 6 is a perspective view from the front side of the F-type plug 1B according to the third embodiment of the present invention. FIG. 7 is a perspective view in which a part of the F-type plug 1B shown in FIG. 6 is cut away.

本第３実施形態に係るＦ型プラグ１Ｂは、図６および図７に示すように、上記第２実施形態に係るＦ型プラグ１Ａにおいて、プラグ部材２の開口部２ａに設けた係止リブ７を、所定の間隔で等間隔に区切った形状の係止リブ７Ａとした構成としている。なお、本第３実施形態において、上記第１および第２実施形態と同一の構成および作用については、その説明を省略している。 As shown in FIGS. 6 and 7, the F-type plug 1B according to the third embodiment is a locking rib 7 provided in the opening 2a of the plug member 2 in the F-type plug 1A according to the second embodiment. Is configured as a locking rib 7A having a shape divided at regular intervals at predetermined intervals. Note that in the third embodiment, descriptions of the same configurations and operations as those of the first and second embodiments are omitted.

係止リブ７Ａは、上記第２実施形態に係るＦ型プラグ１Ａの係止リブ７と同様に、Ｆ型コネクタＢの雄ねじ部Ｂ１のピッチＢ３に対応させた円弧状に形成され、この開口部２ａの周方向に向けて、所定の間隔を介して等間隔に開口部２ａの約１周に亘った螺旋状に形成されている。すなわち、係止リブ７Ａは、所定の間隔を介して、開口部２ａの周方向に向けて、例えば７個ほど設けられており、Ｆ型コネクタＢの雄ねじ部Ｂ１の１ピッチ分に亘って形成されている。 The locking rib 7A is formed in an arc shape corresponding to the pitch B3 of the male threaded portion B1 of the F-type connector B, similarly to the locking rib 7 of the F-type plug 1A according to the second embodiment. In the circumferential direction of 2a, it is formed in a spiral shape over the entire circumference of the opening 2a at equal intervals through a predetermined interval. That is, for example, about seven locking ribs 7A are provided in the circumferential direction of the opening 2a through a predetermined interval, and are formed over one pitch of the male threaded portion B1 of the F-type connector B. Has been.

よって、Ｆ型プラグ１Ｂは、係止リブ７ＡがＦ型コネクタＢの雄ねじ部Ｂ１のねじ溝Ｂ２の端部に当接するまで、この雄ねじ部Ｂ１を開口部２ａに挿入してから、プラグ部材２をＦ型コネクタＢの雄ねじ部Ｂ１に対して相対的に回転させて、係止リブ７ＡをＦ型コネクタＢの雄ねじ部Ｂ１に係合させることにより、Ｆ型コネクタＢの雄ねじ部Ｂ１を開口部２ａ内に抜け止め保持させることができる。 Therefore, the F-type plug 1B is inserted into the opening 2a until the locking rib 7A comes into contact with the end of the screw groove B2 of the male screw B1 of the F-type connector B, and then the plug member 2 is inserted. Is rotated relative to the male screw portion B1 of the F-type connector B, and the locking rib 7A is engaged with the male screw portion B1 of the F-type connector B, whereby the male screw portion B1 of the F-type connector B is opened. It is possible to hold it within 2a.

特に、プラグ部材２の係止リブ７Ａを、所定の間隔を介して等間隔に開口部２ａの約１周に亘った螺旋状に形成している。このため、係止リブ７ＡをＦ型コネクタＢの雄ねじ部Ｂ１のねじ溝Ｂ２に係合させた場合に、所定の間隔を介した各係止リブ７Ａのそれぞれが、雄ねじ部Ｂ１のねじ溝Ｂ２に係合し、これら各係止リブ７Ａのそれぞれがねじ溝Ｂ２の形状に対応して変形等する。よって、上記第２実施形態に係るＦ型プラグ１Ａの係止リブ７に比べ、雄ねじ部Ｂ１のねじ溝Ｂ２との接触面積が狭くなるものの、上記第１および第２実施形態に係るＦ型プラグ１，１Ａに比べ、Ｆ型コネクタＢの雄ねじ部Ｂ１を開口部２ａ内に係止させた場合の抜け止め保持をより確実にできる。 In particular, the locking rib 7A of the plug member 2 is formed in a spiral shape over the entire circumference of the opening 2a at regular intervals with a predetermined interval. For this reason, when the locking rib 7A is engaged with the thread groove B2 of the male threaded portion B1 of the F-type connector B, each of the retaining ribs 7A with a predetermined interval is connected to the threaded groove B2 of the male threaded portion B1. Each of the locking ribs 7A is deformed corresponding to the shape of the thread groove B2. Therefore, compared with the locking rib 7 of the F-type plug 1A according to the second embodiment, the contact area with the screw groove B2 of the male screw portion B1 is narrow, but the F-type plug according to the first and second embodiments. Compared to 1 and 1A, it is possible to more reliably retain the retaining when the male threaded portion B1 of the F-type connector B is locked in the opening 2a.
