Description

開示の実施形態は、電気コネクタに関する。 The disclosed embodiments relate to electrical connectors.

従来、携帯電話機等の電子装置における信号伝送媒体として用いられる同軸ケーブルを例えば印刷配線基板などに接続するための電気コネクタが広く用いられている。 Conventionally, an electrical connector for connecting a coaxial cable used as a signal transmission medium in an electronic apparatus such as a cellular phone to, for example, a printed wiring board has been widely used.

上述したような電気コネクタでは、相手コネクタからの抜去を、嵌合状態のまま同軸ケーブルや電気コネクタを嵌合する方向とは反対の方向に移動させることによって行う。したがって、相手コネクタから抜去するのに必要な力（以下、抜去力と記載する）は小さい方が抜去しやすい。 In the electrical connector as described above, removal from the mating connector is performed by moving the coaxial cable or the electrical connector in a direction opposite to the direction in which the coaxial cable or electrical connector is fitted in the fitted state. Therefore, the smaller the force necessary for removal from the mating connector (hereinafter referred to as removal force), the easier it is to remove.

かかる抜去力が小さいと、意図しない力によって電気コネクタが相手コネクタから外れるおそれがあることから、抜去力は、電気コネクタの使用用途に応じて様々な仕様に合わせることが要求される場合がある。そのため、電気コネクタの共通化を図ることが難しい場合がある。 If the removal force is small, the electrical connector may be detached from the mating connector due to an unintended force. Therefore, the removal force may be required to meet various specifications depending on the intended use of the electrical connector. For this reason, it may be difficult to make the electrical connector common.

実施形態の一態様は、上記に鑑みてなされたものであって、抜去力を高めつつ、相手コネクタから容易に抜去することができる汎用性の高い電気コネクタを提供することを目的とする。 One aspect of the embodiments has been made in view of the above, and an object thereof is to provide a highly versatile electrical connector that can be easily removed from the mating connector while increasing the removal force.

実施形態に係る電気コネクタは、第１コンタクトと、第２コンタクトとを備える。前記第１コンタクトは、導電性を有し、同軸ケーブルの中心導体と電気的に接続された状態で相手コネクタのシグナルコンタクト部に接続される。前記第２コンタクトは、導電性を有し、前記同軸ケーブルの外側導体と電気的に接続された状態で前記相手コネクタのグランドコンタクト部に接続される。前記第２コンタクトは、筒状嵌合部と、嵌合解除部とを備える。前記筒状嵌合部は、周方向の端部同士がスリットを介して対向する筒状に形成され、前記グランドコンタクト部の外周または内周に嵌合される。前記嵌合解除部は、前記筒状嵌合部と前記グランドコンタクト部との嵌合を解除する方向に前記筒状嵌合部の径を変更する。 The electrical connector according to the embodiment includes a first contact and a second contact. The first contact has conductivity and is connected to the signal contact portion of the mating connector while being electrically connected to the central conductor of the coaxial cable. The second contact has conductivity and is connected to the ground contact portion of the mating connector while being electrically connected to the outer conductor of the coaxial cable. The second contact includes a cylindrical fitting part and a fitting release part. The cylindrical fitting portion is formed in a cylindrical shape whose end portions in the circumferential direction face each other via a slit, and is fitted to the outer periphery or inner periphery of the ground contact portion. The fitting release part changes the diameter of the cylindrical fitting part in a direction to release the fitting between the cylindrical fitting part and the ground contact part.

実施形態の一態様によれば、抜去力を高めつつ、相手コネクタから容易に抜去することができる汎用性の高い電気コネクタを提供することができる。 According to one aspect of the embodiment, it is possible to provide a highly versatile electrical connector that can be easily removed from the mating connector while increasing the removal force.

＜１．電気コネクタの概略＞
実施形態に係る電気コネクタは、同軸ケーブルに接続される電気コネクタであり、例えば、印刷配線基板上に実装された相手コネクタに対して嵌合又は抜去される。相手コネクタに対する電気コネクタの嵌合作業および抜去作業は、例えば、印刷配線基板の表面に対して略直交する方向に行われる。以下においては、抜去作業の方向が上方であるものとして説明する。 <1. Outline of electrical connector>
The electrical connector according to the embodiment is an electrical connector connected to a coaxial cable, and is fitted or removed from, for example, a mating connector mounted on a printed wiring board. For example, the fitting operation and the extracting operation of the electrical connector with respect to the mating connector are performed in a direction substantially orthogonal to the surface of the printed wiring board. In the following description, it is assumed that the direction of the extraction work is upward.

実施形態に係る電気コネクタの概要について、図１Ａ〜図１Ｃを参照して説明する。なお、図１Ｂにおいては、切断面以外の部分を省略している。 An outline of the electrical connector according to the embodiment will be described with reference to FIGS. 1A to 1C. In addition, in FIG. 1B, parts other than a cut surface are abbreviate | omitted.

図１Ａおよび図１Ｂに示すように、電気コネクタ１は、同軸ケーブル３に電気的に接続されるコネクタであり、プラグコネクタとも呼ばれる。かかる電気コネクタ１は、絶縁ハウジング部材１１と、導電性を有するシグナルコンタクト部材１２（第１コンタクトの一例）と、導電性を有するグランドコンタクト部材１３（第２コンタクトの一例）とを備える。 As shown in FIGS. 1A and 1B, the electrical connector 1 is a connector that is electrically connected to the coaxial cable 3, and is also called a plug connector. The electrical connector 1 includes an insulating housing member 11, a signal contact member 12 having conductivity (an example of a first contact), and a ground contact member 13 having conductivity (an example of a second contact).

絶縁ハウジング部材１１は、合成樹脂材等の絶縁材料により形成され、シグナルコンタクト部材１２とグランドコンタクト部材１３とを相互に絶縁した状態に維持する。シグナルコンタクト部材１２は、導電性材料によって形成され、中心導体と外側導体とを有する同軸ケーブル３の中心導体に電気的に接続される。グランドコンタクト部材１３は、導電性材料によって形成され、同軸ケーブル３の外側導体に電気的に接続される。 The insulating housing member 11 is formed of an insulating material such as a synthetic resin material, and maintains the signal contact member 12 and the ground contact member 13 in a mutually insulated state. The signal contact member 12 is formed of a conductive material and is electrically connected to the center conductor of the coaxial cable 3 having a center conductor and an outer conductor. The ground contact member 13 is formed of a conductive material and is electrically connected to the outer conductor of the coaxial cable 3.

グランドコンタクト部材１３は、筒状嵌合部１４と、シェル部１５と、ケーブル支持部１６と、嵌合解除部１７とを備える。筒状嵌合部１４は、周方向の端部同士がスリットを介して対向して断面Ｃ字状（筒状）に形成され、径方向に弾性を有する。 The ground contact member 13 includes a cylindrical fitting part 14, a shell part 15, a cable support part 16, and a fitting release part 17. The cylindrical fitting portion 14 is formed in a cross-sectional C-shape (cylindrical shape) with end portions in the circumferential direction facing each other through a slit, and has elasticity in the radial direction.

図１Ｂに示すように、筒状嵌合部１４は、相手コネクタ２のグランドコンタクト部２１の内周に嵌合される。このとき、シグナルコンタクト部材１２の弾性状のバネ部４２が相手コネクタ２のシグナルコンタクト部２２に接触する。これにより、電気コネクタ１が相手コネクタ２に電気的に接続される。筒状嵌合部１４とグランドコンタクト部２１との嵌合は、筒状嵌合部１４の外周に形成された突起状の凸条部５６がグランドコンタクト部２１の内周に形成された溝状の凹条部２４に係合することによって行われるため、抜去力を高めることができる。 As shown in FIG. 1B, the cylindrical fitting portion 14 is fitted to the inner periphery of the ground contact portion 21 of the mating connector 2. At this time, the elastic spring portion 42 of the signal contact member 12 contacts the signal contact portion 22 of the mating connector 2. Thereby, the electrical connector 1 is electrically connected to the mating connector 2. The fitting between the cylindrical fitting portion 14 and the ground contact portion 21 is a groove shape in which the protruding ridges 56 formed on the outer periphery of the cylindrical fitting portion 14 are formed on the inner periphery of the ground contact portion 21. Since it is performed by engaging with the concave ridge portion 24, the extraction force can be increased.

シェル部１５は、図１Ａに示すように、筒状嵌合部１４の前方上部一端から折曲されて絶縁ハウジング部材１１の上方を覆う。ケーブル支持部１６は、中心導体がシグナルコンタクト部材１２に接続された同軸ケーブル３の外側導体に接触して同軸ケーブル３の外側導体と電気的に接続され、同軸ケーブル３を支持する。 As shown in FIG. 1A, the shell portion 15 is bent from the front upper end of the cylindrical fitting portion 14 and covers the upper portion of the insulating housing member 11. The cable support portion 16 supports the coaxial cable 3 by contacting the outer conductor of the coaxial cable 3 whose center conductor is connected to the signal contact member 12 and being electrically connected to the outer conductor of the coaxial cable 3.

嵌合解除部１７は、板状の一対の操作部６５、６６を有しており、抜去作業を行う作業者の操作部６５、６６への操作に基づき、筒状嵌合部１４とグランドコンタクト部２１との嵌合を解除する方向に筒状嵌合部１４の径を変更する。 The fitting release part 17 has a pair of plate-like operation parts 65 and 66, and the cylindrical fitting part 14 and the ground contact are based on an operation to the operation parts 65 and 66 by a worker who performs the removal work. The diameter of the cylindrical fitting part 14 is changed in the direction in which the fitting with the part 21 is released.

筒状嵌合部１４とグランドコンタクト部２１とが嵌合している状態で、図１Ｃに示すように、作業者が嵌合解除部１７の操作部６５、６６を互いに近づく方向に押圧すると、筒状嵌合部１４の径が小さくなる。これにより、筒状嵌合部１４の凸条部５６とグランドコンタクト部２１の凹条部２４との係合状態が解除されるため、作業者は、電気コネクタ１を相手コネクタ２に対して上方に移動させることで、電気コネクタ１を相手コネクタ２から容易に抜去することができる。 When the operator presses the operation parts 65 and 66 of the fitting release part 17 in a direction approaching each other as shown in FIG. 1C in a state where the cylindrical fitting part 14 and the ground contact part 21 are fitted, The diameter of the cylindrical fitting part 14 becomes small. As a result, the engagement state between the ridges 56 of the cylindrical fitting portion 14 and the ridges 24 of the ground contact portion 21 is released, so that the operator can move the electrical connector 1 upward relative to the mating connector 2. The electrical connector 1 can be easily removed from the mating connector 2 by being moved to the position.

このように、実施形態に係る電気コネクタ１によれば、筒状嵌合部１４の径を変更する嵌合解除部１７を備える。そのため、嵌合状態のまま電気コネクタ１を相手コネクタ２から抜去するのに必要な力（抜去力）を調整することなく、嵌合解除部１７を操作することで相手コネクタ２から容易に抜去することができる。したがって、例えば、抜去力の要求仕様のうち最も高い要求仕様以上の抜去力になるように電気コネクタ１を設計することで、電気コネクタ１の共通化を図ることができる。 Thus, according to the electrical connector 1 which concerns on embodiment, the fitting release part 17 which changes the diameter of the cylindrical fitting part 14 is provided. Therefore, it is easily removed from the mating connector 2 by operating the mating release portion 17 without adjusting the force (unplugging force) required to remove the electrical connector 1 from the mating connector 2 in the fitted state. be able to. Therefore, for example, the electrical connector 1 can be made common by designing the electrical connector 1 so that the removal force is equal to or higher than the highest required specification among the required specifications of the removal force.

＜２．電気コネクタ１の構成について＞
以下、実施形態に係る電気コネクタ１の構成についてさらに具体的に説明する。なお、以下において、説明の便宜上、相手コネクタ２に対して電気コネクタ１を差し込む方向（Ｚ軸負方向）を「下方向」とし、その逆方向（Ｚ軸正方向）を「上方向」とする。また、同軸ケーブル３の延伸方向のうち先端へ向かう方向（Ｘ軸正方向）を「前方向」とし、その逆方向（Ｘ軸負方向）を「後方向」とする。また、「上下方向」と「前後方向」の双方に直交する方向（Ｙ軸正負方向）を「左右方向」とする。 <2. About the configuration of the electrical connector 1>

In the following, for convenience of explanation, the direction in which the electrical connector 1 is inserted into the mating connector 2 (Z-axis negative direction) is “downward”, and the opposite direction (Z-axis positive direction) is “upward”. . Further, the direction (X-axis positive direction) toward the tip of the extending direction of the coaxial cable 3 is referred to as “front direction”, and the opposite direction (X-axis negative direction) is referred to as “rear direction”.

＜２．４．２．シェル部１５およびケーブル支持部１６＞
シェル部１５およびケーブル支持部１６は、電気コネクタ１に同軸ケーブル３を取付ける際に、図３に示す状態から、同軸ケーブル３側に向けて屈曲させられる。かかる屈曲に伴い、絶縁ハウジング部材１１の絶縁蓋部３２とシグナルコンタクト部材１２の可動部４５とが同軸ケーブル３側に向けて屈曲させられる。これにより、図２Ｄに示すように、シグナルコンタクト部材１２の中心導体接続部４１によって同軸ケーブル３の中心導体３ａが挟持されて、同軸ケーブル３の中心導体３ａが中心導体接続部４１に電気的に接続される。 <2.4.2. Shell 15 and Cable Support 16>
When the coaxial cable 3 is attached to the electrical connector 1, the shell portion 15 and the cable support portion 16 are bent from the state shown in FIG. 3 toward the coaxial cable 3 side. Along with this bending, the insulating lid portion 32 of the insulating housing member 11 and the movable portion 45 of the signal contact member 12 are bent toward the coaxial cable 3 side. 2D, the central conductor 3a of the coaxial cable 3 is sandwiched by the central conductor connecting portion 41 of the signal contact member 12, and the central conductor 3a of the coaxial cable 3 is electrically connected to the central conductor connecting portion 41. Connected.

また、シェル部１５およびケーブル支持部１６が上述のように同軸ケーブル３側に向けて屈曲させられることによって、筒状嵌合部１４の上方がシェル部１５によって覆われ、同軸ケーブル３の上方がケーブル支持部１６の後述するカバー部５７によって覆われる。 Further, the shell portion 15 and the cable support portion 16 are bent toward the coaxial cable 3 as described above, so that the upper portion of the cylindrical fitting portion 14 is covered by the shell portion 15 and the upper portion of the coaxial cable 3 is The cable support 16 is covered with a cover 57 described later.

ケーブル支持部１６は、カバー部５７と、一対の第１の屈曲係合片５８と、一対の第２の屈曲係合片５９と、一対の第３の屈曲係合片６０とを備える。カバー部５７は、同軸ケーブル３の特に誘電体３ｂおよび外側導体３ｃの上方を覆う。 The cable support portion 16 includes a cover portion 57, a pair of first bending engagement pieces 58, a pair of second bending engagement pieces 59, and a pair of third bending engagement pieces 60. The cover portion 57 covers the coaxial cable 3 particularly above the dielectric 3b and the outer conductor 3c.

一対の第１の屈曲係合片５８は、図３に示すように、カバー部５７の前方部の左右端からそれぞれ同一方向に延伸し、図２Ｃに示すように、先端部が互いに対向するように屈曲される。かかる第１の屈曲係合片５８とカバー部５７によって形成される領域内に、同軸ケーブル３の一部および嵌合解除部１７の一部が配置される。 As shown in FIG. 3, the pair of first bending engagement pieces 58 extend in the same direction from the left and right ends of the front portion of the cover portion 57, and the front end portions face each other as shown in FIG. 2C. To be bent. A part of the coaxial cable 3 and a part of the fitting release part 17 are arranged in a region formed by the first bending engagement piece 58 and the cover part 57.

一対の第２の屈曲係合片５９は、図３に示すように、カバー部５７の前後中央部の左右端からそれぞれ同一方向に延伸し、先端部が互いに対向するように屈曲されることによって、図２Ｃおよび図２Ｄに示すように、同軸ケーブル３の外側導体３ｃを把持する。これにより、同軸ケーブル３の外側導体３ｃがグランドコンタクト部材１３に電気的に接続される。 As shown in FIG. 3, the pair of second bending engagement pieces 59 extends in the same direction from the left and right ends of the front and rear center portions of the cover portion 57, and is bent so that the tip portions face each other. 2C and 2D, the outer conductor 3c of the coaxial cable 3 is gripped. As a result, the outer conductor 3 c of the coaxial cable 3 is electrically connected to the ground contact member 13.

一対の第３の屈曲係合片６０は、図３に示すように、カバー部５７の後方部の左右端からそれぞれ同一方向に延伸し、先端部が互いに対向するように屈曲されることによって、図２Ｃおよび図２Ｄに示すように、同軸ケーブル３の外周被覆材３ｄを把持する。これにより、外周被覆材３ｄの露出部分で同軸ケーブル３がグランドコンタクト部材１３に固定される。 As shown in FIG. 3, the pair of third bending engagement pieces 60 extends in the same direction from the left and right ends of the rear portion of the cover portion 57, and is bent so that the tip portions face each other, As shown in FIG. 2C and FIG. 2D, the outer periphery covering material 3d of the coaxial cable 3 is gripped. Thereby, the coaxial cable 3 is fixed to the ground contact member 13 at the exposed portion of the outer periphery covering material 3d.

＜２．４．３．嵌合解除部１７＞
嵌合解除部１７は、図５および図６に示すように、同軸ケーブル３を介して互いに対向する位置に配置される左右一対の操作レバー６１、６２を備える。 <2.4.3. Fitting release part 17>
As shown in FIGS. 5 and 6, the fitting release unit 17 includes a pair of left and right operation levers 61 and 62 disposed at positions facing each other via the coaxial cable 3.

操作レバー６１、６２は、筒状嵌合部１４の径を変更するためのレバーであり、一端が筒状嵌合部１４の外周部に支持され、他端が自由端である。操作レバー６１、６２の他端側を作業者が操作することによって、筒状嵌合部１４の径が変更される。かかる操作レバー６１、６２は、延伸部６３、６４と、操作部６５、６６とを備える。 The operation levers 61 and 62 are levers for changing the diameter of the cylindrical fitting portion 14, one end is supported by the outer peripheral portion of the cylindrical fitting portion 14, and the other end is a free end. When the operator operates the other end side of the operation levers 61 and 62, the diameter of the cylindrical fitting portion 14 is changed. The operation levers 61 and 62 include extending portions 63 and 64 and operation portions 65 and 66.

操作部６５、６６は、作業者が抜去作業時に押圧操作を行う領域であり、延伸部６３、６４は、作業者の操作によって生じる操作部６５、６６の変位を筒状嵌合部１４の外周部に伝える。かかる延伸部６３、６４は、筒状嵌合部１４の外周部に一端が支持され、同軸ケーブル３の延伸方向に沿って後方に延伸しており、他端に操作部６５、６６が設けられる。 The operation parts 65 and 66 are areas where the operator performs a pressing operation at the time of removal work, and the extending parts 63 and 64 indicate the displacement of the operation parts 65 and 66 caused by the operator's operation on the outer periphery of the cylindrical fitting part 14. Tell the department. One end of each of the extending portions 63 and 64 is supported on the outer peripheral portion of the tubular fitting portion 14, extends rearward along the extending direction of the coaxial cable 3, and operation portions 65 and 66 are provided at the other ends. .

延伸部６３、６４は、筒状嵌合部１４の異なる端部５１、５２側で一端がそれぞれ支持される。かかる延伸部６３、６４は、クランク状に形成される。すなわち、延伸部６３、６４は、同軸ケーブル３の延伸方向と平行に延伸する領域７１、７２と、領域７１、７２と連続し、同軸ケーブル３から離れる方向へ延伸した後に再び軸ケーブル３の延伸方向と平行に延伸する領域７３、７４とを有する。 One end of each of the extending portions 63 and 64 is supported on the different end portions 51 and 52 side of the cylindrical fitting portion 14. The extending portions 63 and 64 are formed in a crank shape. That is, the extending portions 63 and 64 are continuous with the regions 71 and 72 extending in parallel with the extending direction of the coaxial cable 3 and the regions 71 and 72, and after extending in the direction away from the coaxial cable 3, the extending portions of the axial cable 3 again. It has the area | regions 73 and 74 extended | stretched in parallel with a direction.

これにより、図６に示すように、操作レバー６１、６２の後端側で操作レバー６１、６２と対向する部材（ここでは、第２の屈曲係合片５９）との間隔が広くなるため、同軸ケーブル３の方向への操作部６５、６６の可動範囲を適切に確保することができる。 As a result, as shown in FIG. 6, the distance between the operation levers 61 and 62 and the member facing the operation levers 61 and 62 (here, the second bending engagement piece 59) is widened on the rear end side of the operation levers 61 and 62. The movable range of the operation parts 65 and 66 in the direction of the coaxial cable 3 can be appropriately ensured.

また、延伸部６３、６４は、図５に示すように、領域７１、７２の下方部分のみから領域７３、７４が延伸するように延伸部６３、６４が形成される。これにより、領域７１、７２の下方部分に加え上方部分からも領域７３、７４が延伸するとした場合に比べて、カバー部５７のうち下方へ延びる部分である延伸部９１（図２Ｂ、図３、図５参照）を短くしなくて済む。そのため、例えば、図２Ｂに示すように、シェル部１５の上下方向の長さとカバー部５７の上下方向の長さを延伸部９１によって同程度にすることができるため、カバー部５７の強度が低下することを抑制することができる。 Further, as shown in FIG. 5, the extending portions 63 and 64 are formed such that the regions 73 and 74 extend from only the lower portions of the regions 71 and 72. Thereby, compared with the case where the regions 73 and 74 extend from the upper portion in addition to the lower portions of the regions 71 and 72, the extending portion 91 (FIG. 2B, FIG. (See FIG. 5). Therefore, for example, as shown in FIG. 2B, the length of the shell portion 15 in the vertical direction and the length of the cover portion 57 in the vertical direction can be made equal by the extending portion 91, so that the strength of the cover portion 57 is reduced. Can be suppressed.

また、操作部６５、６６は、上下方向の長さが領域７３、７４よりも長い。これにより、電気コネクタ１が携帯電話機などの小型の電子機器に用いられるような小さな部品であっても、作業者による操作部６５、６６に対する操作を容易に行うことができる。 The operation units 65 and 66 are longer in the vertical direction than the regions 73 and 74. Thereby, even if the electrical connector 1 is a small part used in a small electronic device such as a mobile phone, the operator can easily perform operations on the operation units 65 and 66.

また、操作部６５、６６は、図２Ａに示すように、電気コネクタ１における左右方向の位置が、操作部６５、６６を除く電気コネクタ１の幅（左右方向の長さ）内になるように形成される。また、操作部６５、６６は、図２Ｂに示すように、電気コネクタ１における上下方向の位置が、操作部６５、６６を除く電気コネクタ１の厚み（上下方向の長さ）内になるように形成される。これにより、電気コネクタ１の幅や厚みが大きくなることを抑制することができ、電気コネクタ１の小型化を図ることができる。 Further, as shown in FIG. 2A, the operation units 65 and 66 are arranged such that the horizontal position of the electrical connector 1 is within the width (length in the horizontal direction) of the electrical connector 1 excluding the operation units 65 and 66. It is formed. In addition, as shown in FIG. 2B, the operation parts 65 and 66 are arranged such that the vertical position of the electrical connector 1 is within the thickness (length in the vertical direction) of the electrical connector 1 excluding the operation parts 65 and 66. It is formed. Thereby, it can suppress that the width | variety and thickness of the electrical connector 1 become large, and size reduction of the electrical connector 1 can be achieved.

また、延伸部６３、６４は、図６に示すように、第１の屈曲係合片５８と同軸ケーブル３との間に配置されることから、第１の屈曲係合片５８によって同軸ケーブル３から離れる方向への延伸部６３、６４の移動が規制される。これにより、例えば、操作部６５、６６に同軸ケーブル３から離れる方向へ力が働いた場合であっても、延伸部６３、６４の基端部に働く力が制限されることから、例えば、筒状嵌合部１４の塑性変形を抑制することができる。 Further, as shown in FIG. 6, the extending portions 63 and 64 are disposed between the first bending engagement piece 58 and the coaxial cable 3, and thus the first bending engagement piece 58 causes the coaxial cable 3. The movement of the extending portions 63 and 64 in the direction away from the distance is restricted. Thereby, for example, even when a force is applied to the operation portions 65 and 66 in a direction away from the coaxial cable 3, the force acting on the proximal end portions of the extending portions 63 and 64 is limited. The plastic deformation of the fitting portion 14 can be suppressed.

図７および図８は共に電気コネクタ１と相手コネクタ２とが嵌合している状態を示している。なお、図８では、図１Ｂと同様に切断面以外の部分を省略している。 7 and 8 both show a state where the electrical connector 1 and the mating connector 2 are fitted. In FIG. 8, portions other than the cut surface are omitted as in FIG. 1B.

抜去作業を行う作業者により操作部６５、６６が押圧操作されると操作部６５、６６が同軸ケーブル３に近づき、延伸部６３、６４の基端部（延伸部６３、６４の両端部のうち筒状嵌合部１４の外周部に支持される側の端部。以下同様）に同軸ケーブル３に向かう方向の力が働く。そのため、図７に示すように、筒状嵌合部１４の端部５１、５２同士（図５参照）が互いに近づき、筒状嵌合部１４の径Ｄａが小さくなる。 When the operation parts 65 and 66 are pressed by the operator who performs the removal work, the operation parts 65 and 66 approach the coaxial cable 3 and the base ends of the extension parts 63 and 64 (of the both ends of the extension parts 63 and 64). A force in a direction toward the coaxial cable 3 acts on an end portion on the side supported by the outer peripheral portion of the cylindrical fitting portion 14 (the same applies hereinafter). Therefore, as shown in FIG. 7, the end portions 51 and 52 (see FIG. 5) of the cylindrical fitting portion 14 approach each other, and the diameter Da of the cylindrical fitting portion 14 decreases.

これにより、図８に示すように、筒状嵌合部１４と相手コネクタ２のグランドコンタクト部２１との嵌合が解除される。具体的には、筒状嵌合部１４に形成された周方向に沿って連続する凸条部５６とグランドコンタクト部２１の環状嵌合部２３に形成された周方向に沿って連続する凹条部２４との係合状態が解かれ、嵌合が解除される。なお、嵌合の解除とは、嵌合状態が完全になくなることに限定されず、嵌合力が低減されることを含む。 Thereby, as shown in FIG. 8, the fitting between the tubular fitting portion 14 and the ground contact portion 21 of the mating connector 2 is released. Specifically, a convex strip 56 continuous in the circumferential direction formed in the cylindrical fitting portion 14 and a concave strip continuous in the circumferential direction formed in the annular fitting portion 23 of the ground contact portion 21. The engagement state with the portion 24 is released, and the fitting is released. Note that the release of the fitting is not limited to the complete disappearance of the fitting state but includes the reduction of the fitting force.

なお、筒状嵌合部１４に凸条部５６を設け、グランドコンタクト部２１に凹条部２４を設けたが、嵌合するための形状はかかる形状に限定されない。例えば、筒状嵌合部１４に凹条部を設け、グランドコンタクト部２１に凸条部を設けてもよく、筒状嵌合部１４とグランドコンタクト部２１の双方に凸条部と凹条部を設けてもよい。なお、凸条部や凹条部は、周方向の一部に設けられてもよく、周方向の全体に設けられてもよい。また、嵌合するための形状は、凸条部や凹条部以外の形状であってもよい。 In addition, although the protruding item | line part 56 was provided in the cylindrical fitting part 14, and the concave line part 24 was provided in the ground contact part 21, the shape for fitting is not limited to this shape. For example, the cylindrical fitting portion 14 may be provided with a concave stripe portion, and the ground contact portion 21 may be provided with a convex stripe portion. Both the cylindrical fitting portion 14 and the ground contact portion 21 have a convex stripe portion and a concave stripe portion. May be provided. In addition, a protruding item | line part and a recessed item part may be provided in a part of circumferential direction, and may be provided in the whole circumferential direction. Further, the shape for fitting may be a shape other than the ridge portion or the groove portion.

ところで、延伸部６３、６４の基端部に働く力が大きい場合、筒状嵌合部１４に塑性変形が生じるおそれがある。そこで、図５に示すように、延伸部６３、６４は、操作部６５、６６の変位量を制限する規制部６７、６８（ストッパーの一例）を備える。 By the way, when the force which acts on the base end part of the extending | stretching parts 63 and 64 is large, there exists a possibility that plastic deformation may arise in the cylindrical fitting part 14. FIG. Therefore, as illustrated in FIG. 5, the extending portions 63 and 64 include restriction portions 67 and 68 (an example of a stopper) that limit the amount of displacement of the operation portions 65 and 66.

かかる規制部６７、６８は、延伸部６３、６４の領域７１、７２からそれぞれ互いに対向する方向に向けて延伸しており、規制部６７、６８の端部同士は、図９に示すように間隙７９を介して互いに対向する。 The restricting portions 67 and 68 extend from the regions 71 and 72 of the extending portions 63 and 64 in directions facing each other, and the end portions of the restricting portions 67 and 68 are spaced from each other as shown in FIG. 79 to face each other.

操作部６５、６６が同軸ケーブル３へ近づく方向へ操作されると、規制部６７、６８の先端部同士が近づいていき、図１０に示すように、規制部６７、６８の端部同士が当接する。 When the operation portions 65 and 66 are operated in the direction approaching the coaxial cable 3, the tip portions of the restriction portions 67 and 68 approach each other, and as shown in FIG. Touch.

これにより、操作部６５、６６の変位が規制され、延伸部６３、６４の基端に働く力が制限される。したがって、規制部６７、６８の端部同士の間隔Ｄｂ（図９参照）を適切に設定することによって、筒状嵌合部１４の塑性変形を抑制することができる。 Thereby, the displacement of the operation parts 65 and 66 is regulated, and the force acting on the base ends of the extending parts 63 and 64 is limited. Therefore, plastic deformation of the cylindrical fitting portion 14 can be suppressed by appropriately setting the distance Db (see FIG. 9) between the end portions of the restricting portions 67 and 68.

なお、上述した例では、規制部６７、６８の長さを同じとしたが、規制部６７、６８の長さは互いに異なるものであってもよい。また、上述した例では、規制部６７、６８の端部同士を当接させることによって操作部６５、６６の変位を規制するものであるが、かかる例に限定されない。 In the above-described example, the lengths of the restriction portions 67 and 68 are the same. However, the lengths of the restriction portions 67 and 68 may be different from each other. Moreover, in the example mentioned above, although the displacement of the operation parts 65 and 66 is controlled by making the edge parts of the control parts 67 and 68 contact | abut, it is not limited to this example.

図１１に示す電気コネクタ１では、図１０に示す規制部６７、６８のうち一方の規制部６８のみを設け、第１の屈曲係合片５８の先端部が規制部６８の先端部の移動先に含まれるように第１の屈曲係合片５８を屈曲させている。 In the electrical connector 1 shown in FIG. 11, only one of the restricting portions 67 and 68 shown in FIG. 10 is provided, and the distal end of the first bending engagement piece 58 is the destination of the distal end of the restricting portion 68. The first bending engagement piece 58 is bent so as to be included in the above.

この場合、操作部６６が同軸ケーブル３へ近づく方向へ操作されると、規制部６８の先端部が第１の屈曲係合片５８の先端部に近づいて間隙８３が小さくなっていき、かかる第１の屈曲係合片５８の先端部に当接する。これによっても、操作部６６の変位が規制され、筒状嵌合部１４の塑性変形を抑制することができる。 In this case, when the operation portion 66 is operated in a direction approaching the coaxial cable 3, the distal end portion of the restricting portion 68 approaches the distal end portion of the first bending engagement piece 58, and the gap 83 becomes smaller. It abuts on the tip of one bending engagement piece 58. Also by this, the displacement of the operation part 66 is restricted, and the plastic deformation of the cylindrical fitting part 14 can be suppressed.

図１２に示す電気コネクタ１は、上述した規制部６７、６８に代えてまたは加えて、筒状嵌合部１４の周方向の端部５１、５２が操作部６５、６６の変位量を制限する規制部として機能する。図１２に示すように、筒状嵌合部１４の端部５１、５２は、間隔Ｄｃを介して対向している。 In the electrical connector 1 shown in FIG. 12, instead of or in addition to the restricting portions 67 and 68 described above, the end portions 51 and 52 in the circumferential direction of the tubular fitting portion 14 limit the displacement amount of the operation portions 65 and 66. Functions as a regulation unit. As shown in FIG. 12, the end portions 51 and 52 of the cylindrical fitting portion 14 are opposed to each other with a distance Dc.

操作部６５、６６への操作によって操作部６５、６６が同軸ケーブル３へ近づく方向へ操作されると、端部５１、５２の端部同士が近づいていき、図１３に示すように、端部５１、５２の端部同士が当接する。 When the operation units 65 and 66 are operated in a direction approaching the coaxial cable 3 by operating the operation units 65 and 66, the end portions of the end portions 51 and 52 approach each other, as shown in FIG. The ends of 51 and 52 come into contact with each other.

これにより、操作部６５、６６の変位が規制され、延伸部６３、６４の基端に働く力が制限される。したがって、筒状嵌合部１４の周方向の端部５１、５２の間隔Ｄｃ（図１２参照）を適切に設定することによって、筒状嵌合部１４の塑性変形を抑制することができる。 Thereby, the displacement of the operation parts 65 and 66 is regulated, and the force acting on the base ends of the extending parts 63 and 64 is limited. Therefore, plastic deformation of the cylindrical fitting portion 14 can be suppressed by appropriately setting the distance Dc (see FIG. 12) between the circumferential ends 51 and 52 of the cylindrical fitting portion 14.

なお、上述した電気コネクタ１では、嵌合解除部１７として操作レバー６１、６２によって電気コネクタ１と相手コネクタ２との嵌合状態を解除するものであるが、嵌合解除部１７は、操作レバー６１、６２に限定されるものではない。 In the electrical connector 1 described above, the engagement state between the electrical connector 1 and the mating connector 2 is released by the operation levers 61 and 62 as the engagement release portion 17. It is not limited to 61,62.

例えば、図１４に示すように、筒状嵌合部１４の外周に左右に突出する突出部８１、８２を嵌合解除部１７として設けることもできる。図１４に示す電気コネクタ１では、作業者は、操作部６５、６６と同様に突出部８１、８２を左右から例えば、治具等によって押圧することで筒状嵌合部１４の径を小さくすることができる。 For example, as shown in FIG. 14, protrusions 81 and 82 that protrude to the left and right can be provided on the outer periphery of the cylindrical fitting part 14 as the fitting release part 17. In the electrical connector 1 shown in FIG. 14, the operator reduces the diameter of the cylindrical fitting portion 14 by pressing the projecting portions 81 and 82 from the left and right, for example, with a jig or the like, similarly to the operation portions 65 and 66. be able to.

突出部８１、８２は、例えば、筒状嵌合部１４の上端部分の一部を外周側に折り返すことによって形成することができる。また、突出部８１、８２は、筒状嵌合部１４の左右両側に別部材を取り付けることによって構成してもよい。なお、突出部８１、８２のうち一方のみを電気コネクタ１に設ける構成であってもよい。 The protrusions 81 and 82 can be formed, for example, by folding back part of the upper end portion of the cylindrical fitting portion 14 to the outer peripheral side. Further, the projecting portions 81 and 82 may be configured by attaching different members to the left and right sides of the cylindrical fitting portion 14. In addition, the structure which provides only one of the protrusion parts 81 and 82 in the electrical connector 1 may be sufficient.

上述した実施形態では、電気コネクタ１の筒状嵌合部１４が相手コネクタ２のグランドコンタクト部２１の内周に嵌合する例を説明したが、かかる例に限定されず、例えば、以下のように、電気コネクタ１の筒状嵌合部１４が相手コネクタ２のグランドコンタクト部２１の外周を覆うように嵌合してもよい。 In the embodiment described above, the example in which the cylindrical fitting portion 14 of the electrical connector 1 is fitted to the inner periphery of the ground contact portion 21 of the mating connector 2 is described. However, the present invention is not limited to this example. Further, the tubular fitting portion 14 of the electrical connector 1 may be fitted so as to cover the outer periphery of the ground contact portion 21 of the mating connector 2.

図１５および図１６に示すように、電気コネクタ１の筒状嵌合部１４は、内周側に周方向に沿って連続する突起状の凸条部５６を有し、相手コネクタ２のグランドコンタクト部２１は、外周側に周方向に沿って連続する溝状の凹条部２４を有する。そして、筒状嵌合部１４の内周側でグランドコンタクト部２１の外周側に形成された凹条部２４に凸条部５６が係合される。なお、図１６は、図１Ｂと同様に切断面以外の部分を省略している。また、嵌合方法はかかる例に限定されないことは上述の場合と同様である。 As shown in FIG. 15 and FIG. 16, the cylindrical fitting portion 14 of the electrical connector 1 has a protruding ridge 56 continuous along the circumferential direction on the inner peripheral side, and the ground contact of the mating connector 2. The portion 21 has a groove-like concave strip portion 24 that is continuous along the circumferential direction on the outer peripheral side. Then, the convex strip 56 is engaged with the concave strip 24 formed on the inner peripheral side of the cylindrical fitting portion 14 on the outer peripheral side of the ground contact portion 21. Note that, in FIG. 16, portions other than the cut surface are omitted as in FIG. 1B. Moreover, it is the same as that of the above-mentioned that a fitting method is not limited to this example.

筒状嵌合部１４の内周がグランドコンタクト部２１の外周で嵌合する場合、筒状嵌合部１４とグランドコンタクト部２１との嵌合状態を解除するためには、筒状嵌合部１４の径を大きくする必要がある。そこで、図１５に示す電気コネクタ１には、筒状嵌合部１４の径を大きくするために嵌合解除部１７が設けられる。 When the inner periphery of the tubular fitting portion 14 is fitted on the outer periphery of the ground contact portion 21, the tubular fitting portion is used to release the fitting state between the tubular fitting portion 14 and the ground contact portion 21. The diameter of 14 needs to be increased. Accordingly, the electrical connector 1 shown in FIG. 15 is provided with a fitting release portion 17 in order to increase the diameter of the cylindrical fitting portion 14.

図１７に示すように、電気コネクタ１の第１の屈曲係合片５８には、延伸部６３、６４の筒状嵌合部１４側の一端を操作部６５、６６の操作方向と逆方向へ移動させる支持部７７、７８が形成される。 As shown in FIG. 17, the first bent engagement piece 58 of the electrical connector 1 has one end of the extending portions 63, 64 on the cylindrical fitting portion 14 side in the direction opposite to the operation direction of the operation portions 65, 66. Support portions 77 and 78 to be moved are formed.

かかる支持部７７、７８は、例えば、第１の屈曲係合片５８の一部（例えば先端側領域または前後方向中央領域）を同軸ケーブル３から離れる方向に屈曲して形成される。これにより、支持部７７、７８を容易に形成することができる。なお、支持部７７、７８は、例えば、第１の屈曲係合片５８にその他の部材を取り付けることによって形成してもよい。また、延伸部６３、６４の一部（例えば先端側領域）を同軸ケーブル３に近づく方向に屈曲して形成してもよい。 The support portions 77 and 78 are formed, for example, by bending a part of the first bending engagement piece 58 (for example, the front end side region or the front-rear direction central region) in a direction away from the coaxial cable 3. Thereby, the support parts 77 and 78 can be formed easily. In addition, you may form the support parts 77 and 78 by attaching another member to the 1st bending engagement piece 58, for example. Further, a part of the extending portions 63 and 64 (for example, the tip side region) may be bent in a direction approaching the coaxial cable 3.

抜去作業を行う作業者により操作部６５、６６が押圧操作されると操作部６５、６６が同軸ケーブル３に近づくが、支持部７７、７８が支点となって延伸部６３、６４の筒状嵌合部１４側の一端が操作部６５、６６の操作方向と逆方向へ移動する。そのため、図１８に示すように、筒状嵌合部１４の端部５１、５２同士（図示せず）が互いに遠ざかり、筒状嵌合部１４の径が大きくなる。これにより、筒状嵌合部１４と相手コネクタ２のグランドコンタクト部２１との嵌合が解除される。 When the operation parts 65 and 66 are pressed by the operator who performs the removal work, the operation parts 65 and 66 approach the coaxial cable 3, but the support parts 77 and 78 serve as fulcrums and the extension parts 63 and 64 are fitted into the cylindrical shape. One end of the joint portion 14 side moves in the direction opposite to the operation direction of the operation portions 65 and 66. Therefore, as shown in FIG. 18, the end portions 51 and 52 (not shown) of the cylindrical fitting portion 14 are moved away from each other, and the diameter of the cylindrical fitting portion 14 is increased. Thereby, the fitting between the cylindrical fitting portion 14 and the ground contact portion 21 of the mating connector 2 is released.

なお、上述した実施形態では、相手コネクタ２のグランドコンタクト部２１は、内周または外周の少なくとも一方が円環状に形成されているが、筒状嵌合部１４が嵌合できる形状であればよく、グランドコンタクト部２１は円環状に限定されるものではない。 In the above-described embodiment, the ground contact portion 21 of the mating connector 2 is formed in an annular shape at least one of the inner periphery and the outer periphery, but may be any shape as long as the cylindrical fitting portion 14 can be fitted. The ground contact portion 21 is not limited to an annular shape.

また、上述した実施形態では、２つの操作部６５、６６を設ける例を示したが、操作部６５、６６のうち一方のみを設ける構成であってもよく、この場合、延伸部６３、６４の領域７３、７４のうち一方を設けなくてよい。 Moreover, although the example which provides the two operation parts 65 and 66 was shown in embodiment mentioned above, the structure which provides only one of the operation parts 65 and 66 may be sufficient, and in this case, the extension parts 63 and 64 are provided. One of the regions 73 and 74 may not be provided.

以上のように、実施形態に係る電気コネクタ１は、シグナルコンタクト部材１２（第１コンタクトの一例）と、グランドコンタクト部材１３（第２コンタクトの一例）とを備える。シグナルコンタクト部材１２は、導電性を有し、同軸ケーブル３の中心導体３ａと電気的に接続された状態で相手コネクタ２のシグナルコンタクト部２２に接続される。グランドコンタクト部材１３は、導電性を有し、同軸ケーブル３の外側導体３ｃと電気的に接続された状態で相手コネクタ２のグランドコンタクト部２１に接続される。かかるグランドコンタクト部材１３は、筒状嵌合部１４と嵌合解除部１７とを備える。筒状嵌合部１４は、周方向の端部５１、５２同士がスリット５３を介して対向する筒状に形成され、グランドコンタクト部２１の外周または内周に嵌合される。嵌合解除部１７は、筒状嵌合部１４とグランドコンタクト部２１との嵌合を解除する方向に筒状嵌合部１４の径を変更する。これにより、抜去力を高めつつ、相手コネクタ２から容易に抜去することができる汎用性の高い電気コネクタを提供することができる。 As described above, the electrical connector 1 according to the embodiment includes the signal contact member 12 (an example of the first contact) and the ground contact member 13 (an example of the second contact). The signal contact member 12 has conductivity, and is connected to the signal contact portion 22 of the mating connector 2 in a state of being electrically connected to the central conductor 3 a of the coaxial cable 3. The ground contact member 13 has conductivity and is connected to the ground contact portion 21 of the mating connector 2 in a state of being electrically connected to the outer conductor 3 c of the coaxial cable 3. The ground contact member 13 includes a cylindrical fitting portion 14 and a fitting release portion 17. The cylindrical fitting portion 14 is formed in a cylindrical shape in which the end portions 51 and 52 in the circumferential direction are opposed to each other via the slit 53, and is fitted to the outer periphery or inner periphery of the ground contact portion 21. The fitting release part 17 changes the diameter of the cylindrical fitting part 14 in a direction in which the fitting between the cylindrical fitting part 14 and the ground contact part 21 is released. Thereby, it is possible to provide a highly versatile electrical connector that can be easily removed from the mating connector 2 while increasing the removal force.

また、嵌合解除部１７は、筒状嵌合部１４の外周部に一端が支持される延伸部６３、６４と、延伸部６３、６４の他端に設けられる操作部６５、６６とを備える。したがって、延伸部６３、６４と操作部６５、６６とにより自由端を有する操作レバー６１、６２が形成され、かかる操作レバー６１、６２の自由端へのユーザ操作によって、比較的容易に電気コネクタ１を相手コネクタ２から抜去することができる。 Further, the fitting release part 17 includes extending parts 63 and 64 whose one ends are supported on the outer peripheral part of the cylindrical fitting part 14, and operation parts 65 and 66 provided on the other ends of the extending parts 63 and 64. . Therefore, the extending portions 63 and 64 and the operating portions 65 and 66 form operating levers 61 and 62 having free ends, and the electric connector 1 can be relatively easily operated by a user operation on the free ends of the operating levers 61 and 62. Can be removed from the mating connector 2.

また、延伸部６３、６４は、同軸ケーブル３に沿って延伸する。このように、操作レバー６１、６２の延伸部６３、６４が同軸ケーブル３の延伸方向に沿って延伸していることから、例えば、電気コネクタ１の大型化を避けることができる。 The extending portions 63 and 64 extend along the coaxial cable 3. Thus, since the extending portions 63 and 64 of the operation levers 61 and 62 extend along the extending direction of the coaxial cable 3, for example, an increase in size of the electrical connector 1 can be avoided.

また、延伸部６３、６４および操作部６５、６６はそれぞれ一対ずつ設けられる。そして、当該一対の延伸部６３、６４は、筒状嵌合部１４の異なる端部５１、５２側で一端がそれぞれ支持される。このように、異なる端部５１、５２側に支持される２つの操作レバー６１、６２を有することから、例えば、操作レバーが一つである場合に比べ、筒状嵌合部１４の径を効率的に変更することができる。 A pair of extending portions 63 and 64 and operating portions 65 and 66 are provided. Then, one end of each of the pair of extending portions 63 and 64 is supported on the different end portions 51 and 52 side of the cylindrical fitting portion 14. As described above, since the two operation levers 61 and 62 are supported on the different end portions 51 and 52 side, for example, the diameter of the cylindrical fitting portion 14 is made more efficient than in the case where there is one operation lever. Can be changed.

また、一対の延伸部６３、６４は、同軸ケーブル３を介して互いに対向する位置に配置される。これにより、筒状嵌合部１４の操作性を高めることができ、電気コネクタ１を相手コネクタ２から容易に抜去することができる。 Further, the pair of extending portions 63 and 64 are disposed at positions facing each other via the coaxial cable 3. Thereby, the operativity of the cylindrical fitting part 14 can be improved, and the electrical connector 1 can be easily extracted from the mating connector 2.

また、嵌合解除部１７は、筒状嵌合部１４の端部５１、５２同士の当接によって操作部６５、６６の変位を規制する。これにより、例えば、筒状嵌合部１４の端部５１、５２間の間隔を適切に設定することによって、筒状嵌合部１４の塑性変形を抑制することができる。 Further, the fitting release part 17 regulates the displacement of the operation parts 65 and 66 by the contact between the end parts 51 and 52 of the cylindrical fitting part 14. Thereby, plastic deformation of the cylindrical fitting part 14 can be suppressed, for example, by appropriately setting the interval between the end parts 51 and 52 of the cylindrical fitting part 14.

また、嵌合解除部１７は、一対の延伸部６３、６４のうち少なくとも一方に設けられ、操作部６５、６６の変位量を制限する規制部６７、６８（ストッパーの一例）を備える。これにより、例えば、筒状嵌合部１４の塑性変形を抑制することができる。 Moreover, the fitting release part 17 is provided in at least one of a pair of extending | stretching parts 63 and 64, and is provided with the regulation parts 67 and 68 (an example of a stopper) which restrict | limit the displacement amount of the operation parts 65 and 66. FIG. Thereby, plastic deformation of the cylindrical fitting part 14 can be suppressed, for example.

また、規制部６７、６８は、一対の延伸部６３、６４のそれぞれに対して設けられる。嵌合解除部１７は、一対の延伸部６３、６４の規制部６７、６８同士の当接によって操作部６５、６６の変位を規制する。これにより、例えば、規制部６７、６８間の間隔を適切に設定することによって、筒状嵌合部１４の塑性変形を抑制することができる。 Further, the restricting portions 67 and 68 are provided for each of the pair of extending portions 63 and 64. The fitting release unit 17 regulates the displacement of the operation units 65 and 66 by the contact between the regulating units 67 and 68 of the pair of extending units 63 and 64. Thereby, for example, plastic deformation of the cylindrical fitting portion 14 can be suppressed by appropriately setting the interval between the restricting portions 67 and 68.

また、実施形態に係る電気コネクタ１は、筒状嵌合部１４が相手コネクタ２のグランドコンタクト部２１の外周に嵌合され、また、操作部６５、６６が所定方向に移動した場合に、延伸部６３、６４の一部を支持し、延伸部６３、６４の一端を所定方向と逆方向へ移動させる支持部７７、７８を備える。これにより、筒状嵌合部１４がグランドコンタクト部２１の外周と嵌合する場合であっても、嵌合状態を容易に解除することができる。 Further, the electrical connector 1 according to the embodiment is extended when the cylindrical fitting portion 14 is fitted to the outer periphery of the ground contact portion 21 of the mating connector 2 and the operation portions 65 and 66 are moved in a predetermined direction. Support portions 77 and 78 are provided for supporting a part of the portions 63 and 64 and moving one end of the extending portions 63 and 64 in a direction opposite to the predetermined direction. Thereby, even if it is a case where the cylindrical fitting part 14 fits with the outer periphery of the ground contact part 21, a fitting state can be cancelled | released easily.
