Description

本発明はコネクタに関するものである。 The present invention relates to a connector.

従来より、雌雄コネクタのうち一方側が相手側コネクタを待ち受ける方式のコネクタが知られている。そのような待ち受けタイプのコネクタとして下記特許文献１のものを挙げることができる。 Conventionally, there has been known a connector of a type in which one side of a male and female connector waits for a mating connector. An example of such a standby type connector is disclosed in Patent Document 1 below.

ここには、車両のドアフレーム側に雌コネクタが待ち受けており、ドアフレームに装着されるドアトリム側に雄コネクタを装着した構成が開示されている。また、ドアトリム側にはホルダが取付けられており、雄コネクタはホルダに対してフローティング状態で支持されるようになっている。すなわち、ホルダは雄コネクタに設けられた軸部を取り囲むようにして４つの弾性リブを設けて、これらによって雄コネクタをＸ，Ｙ平面内で変位できるようにしている。こうすることで、雌雄のコネクタを嵌合する際に、互いの結合軸線がずれていたとしても、このずれを吸収して円滑な嵌合を実現することができる。 Here, a configuration is disclosed in which a female connector is waiting on the door frame side of the vehicle, and a male connector is mounted on the door trim side mounted on the door frame. A holder is attached to the door trim side, and the male connector is supported in a floating state with respect to the holder. That is, the holder is provided with four elastic ribs so as to surround the shaft portion provided in the male connector, and thereby the male connector can be displaced in the X and Y planes. By doing so, even when the male and female connectors are fitted, even if the mutual coupling axes are displaced, this displacement can be absorbed and smooth fitting can be realized.

特開２００１−１２６８２１号公報Japanese Patent Laid-Open No. 2001-126721

上記のように、ホルダに対してフローティング状態で支持されたコネクタは、雌雄の嵌合後においても、フローティング構造によって車両の振動をある程度は吸収することが期待できる。しかし、コネクタとホルダとは接触部分を有していることから、コネクタへの振動伝達を完全には回避し得ない。 As described above, the connector supported in a floating state with respect to the holder can be expected to absorb the vibration of the vehicle to some extent by the floating structure even after the male and female are fitted. However, since the connector and the holder have contact portions, vibration transmission to the connector cannot be completely avoided.

本発明は上記のような事情に基づいて完成されたものであって、ホルダによって保持されている形式のコネクタにおいて、振動の伝達を有効に回避することができるコネクタの提供を目的とする。 The present invention has been completed based on the above circumstances, and an object of the present invention is to provide a connector that can effectively avoid transmission of vibration in a connector of a type held by a holder.

本発明のコネクタは、第１コネクタと、この第１コネクタを軸方向に沿って嵌合可能な第２コネクタと、第１コネクタを、軸方向に関して抜け止めされる初期位置と軸方向に関して分離可能な分離位置との間を変位可能に保持する第１ホルダ部と、第２コネクタを、軸方向に関して抜け止めされる初期位置と軸方向に関して分離可能な分離位置との間を変位可能に保持する第２ホルダ部とを備え、第１ホルダ部あるいは第２ホルダ部の少なくとも一方には、両ホルダ部の軸方向に沿った接近動作に伴い、前記第１コネクタと前記第２コネクタを前記初期位置から前記分離位置へ誘導するとともに、誘導の過程で前記第１コネクタと前記第２コネクタの嵌合を完了させる誘導手段が設けられ、前記分離位置では、前記第１コネクタと前記第２コネクタが嵌合状態のままで前記第１ホルダ部及び前記第２ホルダ部から分離可能であることを特徴とする。 The connector of the present invention can be separated in the axial direction from the initial position where the first connector, the second connector in which the first connector can be fitted along the axial direction, and the first connector are prevented from coming off in the axial direction. A first holder portion that holds the first connector portion so as to be displaceable between the first and second separation positions, and a second connector that holds the second connector so that the second connector can be displaced between an initial position that is prevented from coming off in the axial direction and a separation position that is separable in the axial direction. A second holder portion, and at least one of the first holder portion and the second holder portion is moved to move the first connector and the second connector to the initial position in accordance with an approaching operation along the axial direction of both holder portions. thereby guided to the separated position from, is provided guide means to complete the fitting of the first connector and the second connector in the course of induction, and in the separation position, the second co and said first connector Kuta is characterized in that it is separated from the first holder portion and the second holder part remains fitted state.

本発明によれば、雌雄のコネクタの嵌合前は、第１ホルダ部あるいは第２ホルダ部に対して初期位置に保持されて、軸方向に抜け止めされた状態となっている。しかし、第１、第２の両ホルダ部が軸方向に沿って接近する動作に伴って、両コネクタは誘導手段の作用によって嵌合完了に至るとともに、各ホルダ部において初期位置から分離位置へと移動する。分離位置においては、両コネクタは対応するホルダから軸方向に分離可能となり、ホルダによる保持から解放可能となる。かくして、両コネクタにはホルダの振動が伝達されないため、コネクタ内に収容された端子間の接触状況を良好なものとすることができる。 According to the present invention, before the male and female connectors are fitted, they are held in the initial position with respect to the first holder part or the second holder part and are prevented from coming off in the axial direction. However, as both the first and second holder parts approach along the axial direction, the connectors are completely fitted by the action of the guiding means, and the respective holder parts move from the initial position to the separated position. Moving. In the separation position, both connectors can be separated from the corresponding holders in the axial direction and can be released from being held by the holders. Thus, since the vibration of the holder is not transmitted to both connectors, the contact state between the terminals accommodated in the connectors can be improved.

本発明における好ましい実施の形態を説明する。
（１）本発明のコネクタは、前記第１コネクタが前記第１ホルダ部に対し、また前記第２コネクタが前記第２ホルダ部に対して共に軸心周りに回動可能に取付けられて、共に前記初期位置と前記分離位置との間を回動により変位する構成としてもよい。
仮に、両コネクタを対応するホルダ部に対し軸方向に変位させて初期位置と分離位置との間を移動するようにした場合には、対応するホルダ部が軸方向に大型化することになるが、上記のような構成によれば、両コネクタを、対応するホルダの軸周りに回転させてホルダから分離させることができるため、ホルダ部が軸方向に長大化する事態を回避することができる。 A preferred embodiment of the present invention will be described.
(1) In the connector according to the present invention, the first connector is attached to the first holder part and the second connector is attached to the second holder part so as to be rotatable around an axis, It is good also as a structure displaced by rotation between the said initial position and the said separation position.
If both connectors are displaced in the axial direction with respect to the corresponding holder parts and moved between the initial position and the separation position, the corresponding holder parts will be enlarged in the axial direction. According to the configuration as described above, since both the connectors can be rotated around the axis of the corresponding holder and separated from the holder, a situation in which the holder portion is elongated in the axial direction can be avoided.

（２）また、
前記第２コネクタは、前記初期位置と前記分離位置との角度範囲の途中に、前記第２ホルダ部に対し抜き差し自在となる組み付け位置が設定されるようにしてもよい。
このような構成によれば、第２コネクタを第２ホルダ部に対し組み付け位置において差し込み、その後に、一旦、分離位置とは逆の回転方向である初期位置に向けて回転させ同位置において保持しておく。そして、両コネクタの嵌合がなされると、第２コネクタは組み付け位置を通過して分離位置に至る。この間、第２コネクタから導出される電線は組み付け位置で中立状態にあったとすると、初期位置に至る間にねじられることになるが、嵌合に伴って一旦ねじりが戻された後、分離位置に至るまでの間、逆方向にねじられる。したがって、組み付け位置、初期位置、分離位置をこの順で一方向に設定した場合と比較して電線のねじれの程度を軽減することができる。 (2) Also,
The second connector may be set at an assembly position in which the second connector can be inserted into and removed from the second holder part in the middle of the angular range between the initial position and the separation position.
According to such a configuration, the second connector is inserted into the second holder portion at the assembly position, and then rotated once toward the initial position that is the rotation direction opposite to the separation position and held at the same position. Keep it. When the two connectors are fitted, the second connector passes through the assembly position and reaches the separation position. During this time, assuming that at the neutral state in wire to be second connector or found derivation assembly position, but will be twisted while reaching the initial position, after the twisting is returned once with the fitting, the separation position Until it is twisted in the opposite direction. Therefore, the degree of twisting of the electric wire can be reduced as compared with the case where the assembly position, initial position, and separation position are set in one direction in this order.

（３）さらに、前記第２コネクタには一対の作動翼部が外方に向けて張り出し形成される一方、前記第１コネクタには撓み可能で先端部に爪部を有する一対の保持爪が形成され、前記第１ホルダ部は、前記第１コネクタを嵌合可能で軸方向両端が開口する円筒形状に形成されるとともに、その側面には前記保持爪が係止することで前記第１コネクタを前記初期位置に保持させる一対の窓孔が開口し、また前記第１ホルダ部の前端面には軸方向に沿って導入部が形成されかつこの導入部は前記窓孔の全体に連通するように形成され、さらに前記導入部は前記第１、第２コネクタが嵌合するときに前記作動翼部の先端部の進入を許容して前記窓孔内に係止している前記爪部を、前記窓孔に対し径方向外方へ後退させて前記第１ホルダ部に対する前記第１コネクタの前記初期位置での保持状態を解除可能とさせ、また、前記第１ホルダ部の内周面には、前記誘導手段である一対のカム面が前記導入部の奥端部を始端として前記第１ホルダ部の内周面に沿いつつ奥方へ向けて螺旋状に延出して形成され、かつ前記カム面は前記第１ホルダ部の前方へ対向するようにして形成されて、前記第１、第２コネクタの嵌合時に前記作動翼部の先端部と摺接することで、前記第１、第２コネクタを軸芯周りに回動させて前記第１、第２コネクタをそれぞれ前記分離位置へと至らせる構成とすると良い。 (3) Further, the second connector has a pair of operating wings projecting outward, while the first connector has a pair of holding claws that can be bent and have a claw at the tip. The first holder portion is formed in a cylindrical shape in which the first connector can be fitted and both ends in the axial direction are open, and the holding claw is engaged with a side surface of the first holder portion. A pair of window holes to be held at the initial position are opened, and an introduction portion is formed along the axial direction on the front end surface of the first holder portion, and the introduction portion communicates with the entire window hole. The claw portion formed and further, the claw portion being allowed to enter the tip end portion of the operating wing portion when the first and second connectors are fitted and locked in the window hole, Retracting radially outward with respect to the window hole, the front with respect to the first holder part The holding state of the first connector at the initial position can be released, and a pair of cam surfaces as the guiding means are arranged at the inner end surface of the first holder portion to start from the back end portion of the introduction portion. And extending along the inner peripheral surface of the first holder portion while spirally extending toward the back, and the cam surface is formed so as to face the front of the first holder portion. 1. When the second connector is fitted, the first and second connectors are rotated around the axis by slidingly contacting the tip of the operating wing portion, and the first and second connectors are moved to the separated positions, respectively. It is good to have a configuration that leads to

このような構成によれば、第１コネクタが第１ホルダ部に、また第２コネクタが第２ホルダ部にそれぞれ取付けられた状態で、第１コネクタと第２コネクタの嵌合が開始すると、第２コネクタに形成された作動翼部の先端部が導入部へ進入し、窓孔に係止している第１コネクタの爪部に当接して爪部を窓部から押し出す方向（径方向外方）に後退させる。これにより、初期位置における保持状態が解除可能な状態となる。 According to such a configuration, when fitting of the first connector and the second connector is started in a state where the first connector is attached to the first holder part and the second connector is attached to the second holder part, (2) Direction in which the tip of the operating wing formed on the connector enters the introduction part and abuts the claw part of the first connector locked in the window hole to push the claw part out of the window part (outward in the radial direction) ). As a result, the holding state at the initial position can be released.

この後、第１、第２コネクタの嵌合が進む間、作動翼部の先端部はカム面に沿って摺接することで、第１、第２のコネクタは嵌合したまま一体となって軸心周りに回動して、対応する各ホルダ部に対し分離位置に至り、両コネクタは同位置において各ホルダ部から分離する。 After that, while the fitting of the first and second connectors proceeds, the tip of the working blade part is slidably contacted along the cam surface, so that the first and second connectors are fitted together and the shaft is integrated. By rotating around the center, the respective holder parts are separated from each other, and both connectors are separated from each holder part at the same position.

また、第１ホルダ部において、窓孔はその全体が、第１ホルダの前端面から軸方向に沿って形成された導入部に連通するように形成されている。つまり、導入部を成形することで、窓孔の成形が可能となっている。さらに、両カム面は第１ホルダ部の前方へ対向するように形成している。つまり、第１ホルダ部において、窓孔およびカム面を軸方向に開閉する金型によって形成可能であり、軸方向と直交して開閉するようなスライド型を必要としないため、簡易な構造の金型によって第１ホルダ部全体を形成可能である。したがって、第１ホルダ部を安価に製造することができる。 In the first holder portion, the entire window hole is formed so as to communicate with the introduction portion formed along the axial direction from the front end surface of the first holder. That is, the window hole can be formed by forming the introduction portion. Further, both cam surfaces are formed to face the front of the first holder part. In other words, the first holder portion can be formed by a mold that opens and closes the window hole and the cam surface in the axial direction, and does not require a slide mold that opens and closes perpendicularly to the axial direction. The entire first holder part can be formed by a mold. Therefore, the first holder part can be manufactured at low cost.

（４）さらにまた、前記第２コネクタの一端部には周方向に沿ってフランジ部が外向きに張り出し形成されるとともに、このフランジ部の周縁部には少なくとも一対の切欠き凹所が切欠き形成される一方、前記第２ホルダ部において前記第２コネクタの前記フランジ部と対向する側の端部には前記第２コネクタを取付けるための装着部が形成され、この装着部には、前記第２ホルダ部の端縁部に形成されて前記フランジ部に当接する座面と、この座面の軸方向前方において内向きに張出し形成される少なくとも一対の抜け止め片とが形成され、前記フランジ部は、前記各抜け止め片と前記各切欠き凹所とを整合させることで前記抜け止め片を通過して前記座面へ当接可能であるとともに、前記第２コネクタは前記フランジ部を前記座面に当接させた状態で軸周りに回動したときには、前記第２コネクタは前記フランジ部が前記座面との間で挟み込まれつつ前記抜け止め片に係止して抜け止めされた状態で前記初期位置に保持可能となっており、前記第２コネクタが前記第２ホルダ部に対して前記初期位置から軸周りに回動されたときには、前記切欠き凹所と前記抜け止め片とが整合して前記フランジ部が前記装着部から抜き取り可能な前記分離位置に至ることができるようになっており、さらに、前記座面のうち前記抜け止め片の背面側に対応する位置には型抜き用の抜き孔が貫通して形成されるようにすると良い。 (4) Furthermore, a flange portion projects outward in the circumferential direction at one end portion of the second connector, and at least a pair of notch recesses are cut out in the peripheral portion of the flange portion. On the other hand, a mounting portion for mounting the second connector is formed at the end of the second holder portion on the side facing the flange portion of the second connector. A bearing surface formed on an edge of the holder portion and contacting the flange portion; and at least a pair of retaining pieces extending inwardly in front of the seat surface in the axial direction. The stoppers can be brought into contact with the seating surface by passing through the stopper pieces by aligning the stopper pieces with the notch recesses, and the second connector allows the flange portion to be in contact with the seat portion. Abutting on the surface When the second connector is rotated around the shaft in the closed state, the second connector is in the initial position in a state where the flange portion is held between the seating surface and locked to the retaining piece while being retained. When the second connector is pivoted about the axis from the initial position with respect to the second holder portion, the notch recess and the retaining piece are aligned and the flange is The part can reach the separation position where it can be removed from the mounting part, and a punching hole for punching is provided at a position corresponding to the back side of the retaining piece in the seat surface. It may be formed so as to penetrate.

このような構成によれば、第２コネクタを第２ホルダ部に保持させる場合には、フランジ部の切欠き凹所を装着部の対応する抜け止め片に適合させることでフランジ部を座面に当接させることができる。その状態で、第２コネクタを軸周りに回動させると、フランジ部は抜け止め片と座面との間で挟み付けられかつ抜け止め片との係止によって抜け止めされた状態で初期位置に保持される。 According to such a configuration, when the second connector is held by the second holder part, the flange part is adapted to the seating surface by adapting the notch recess of the flange part to the corresponding retaining piece of the mounting part. It can be made to contact. In this state, when the second connector is rotated around the axis, the flange portion is sandwiched between the retaining piece and the seating surface and kept in the initial position while being retained by the locking with the retaining piece. Retained.

また、第２コネクタは初期位置から所定角度だけ回動すると、抜け止め片と切欠き凹所とが整合する分離位置に至るため、同位置において第２ホルダ部から分離可能となる。 Further, when the second connector is rotated by a predetermined angle from the initial position, the second connector reaches a separation position where the retaining piece and the cutout recess are aligned with each other, so that the second connector can be separated from the second holder portion at the same position.

また、座面のうち抜け止め片の背面側に対応する部位に抜き孔を形成することで、第２ホルダ部の装着部を軸方向に開閉する金型によって成形可能であり、スライド型を必要としないため、第２ホルダ部全体を簡易な構造の金型によって成形することができる。したがって、第２ホルダ部を安価に製造することができる。 In addition, by forming a hole in the seat surface corresponding to the back side of the retaining piece, the mounting portion of the second holder portion can be formed by a mold that opens and closes in the axial direction, and a slide die is required. Therefore, the entire second holder part can be formed by a mold having a simple structure. Therefore, the second holder part can be manufactured at low cost.

＜実施例＞
次に、本発明のコネクタを具体化した実施例について、図面を参照しつつ説明する。
図１に示すように、雌雄のコネクタＦ，Ｍはそれぞれ対応する雌ホルダ１及び雄ホルダ２に対して装着されている。本実施例では、雄コネクタＭ側は機器側に装着されて雌コネクタＦ側の嵌合を待ち受ける待ち受け側としてある。これに対し、雌コネクタＦ側は機器に装着される部品側に装着されており、部品を機器側に装着する作業に伴って雌雄コネクタＦ，Ｍの嵌合がなされるようになっている。まず、雌側の構造を説明する。 <Example>
Next, an embodiment embodying the connector of the present invention will be described with reference to the drawings.
As shown in FIG. 1, male and female connectors F and M are attached to corresponding female holder 1 and male holder 2, respectively. In the present embodiment, the male connector M side is a standby side that is mounted on the device side and waits for the fitting on the female connector F side. On the other hand, the female connector F side is mounted on the component side mounted on the device, and the male and female connectors F and M are fitted together with the operation of mounting the component on the device side. First, the structure on the female side will be described.

＜雌ホルダ１＞
図３及び図４等に示される雌ホルダ１は合成樹脂製であり、軸方向に長い円筒形状に形成されている。雌ホルダ１の一端側には径方向外方へ一対の取付け片３が突出形成されている。両取付け片３にはねじ締め用の穴４が開口し、図示しない部品側への固定が可能である。 <Female holder 1>
The female holder 1 shown in FIGS. 3 and 4 is made of a synthetic resin and is formed in a cylindrical shape that is long in the axial direction. On one end side of the female holder 1, a pair of attachment pieces 3 are formed to project outward in the radial direction. Both mounting pieces 3 have holes 4 for screw tightening, and can be fixed to a component side (not shown).

図３、図４に示すように、雌ホルダ１の周壁には他端側の開口面から一対の逃がし溝５が軸方向に沿って所定長さ範囲に亘って開口して形成されている。両逃がし溝５が設けられている周方向に関する位置は、両取付け片３の突出方向とは僅かに周方向へずれた位置に設定されている。図３に示すように、雌ホルダ１の他端側の開口面には雌コネクタＦを取り付けるための雌コネクタ装着部６が形成されている。雌コネクタ装着部６において、雌ホルダ１の他端側開口面から僅かに内方へ入った深さ位置において、雌ホルダ１の内周面からはリング状の座面７が全周に亘って内向きに張り出し形成されている。 As shown in FIGS. 3 and 4, a pair of escape grooves 5 are formed in the peripheral wall of the female holder 1 so as to open over a predetermined length range along the axial direction from the opening surface on the other end side. The position in the circumferential direction where the both escape grooves 5 are provided is set to a position slightly shifted in the circumferential direction from the protruding direction of the both attachment pieces 3. As shown in FIG. 3, a female connector mounting portion 6 for attaching the female connector F is formed on the opening surface on the other end side of the female holder 1. In the female connector mounting portion 6, a ring-shaped seat surface 7 extends over the entire circumference from the inner peripheral surface of the female holder 1 at a depth position slightly inward from the opening surface on the other end side of the female holder 1. It is formed to project inward.

図３に示すように、座面７の外面側には略９０度間隔毎にリブ８が配されている。具体的には、各リブ８は両逃がし溝５に対応した位置に一対と、ここから９０度ずれた位置に他の一対が設けられている。いずれのリブ８も弧状をなして外面側に突出して形成されている。これらリブ８は雌コネクタＦが雌ホルダ１に対して回動する際の摩擦抵抗を低減させて変位動作を円滑に行わせるためのものである。また、雌ホルダ１の他端側開口縁には略９０度間隔毎に計４個の抜け止め片９が径方向内向きに張り出し形成されている。各抜け止め片９とリブ８とは略４５度の位相差が設けられている。座面７のうち両抜け止め片９の軸方向背面には抜け止め片の形成範囲と対応して型抜きのための抜き孔１０が開口している。 As shown in FIG. 3, ribs 8 are arranged on the outer surface side of the seat surface 7 at intervals of about 90 degrees. Specifically, each rib 8 is provided with a pair at a position corresponding to both escape grooves 5 and another pair at a position shifted by 90 degrees therefrom. Each of the ribs 8 is formed in an arc shape so as to protrude to the outer surface side. These ribs 8 are for reducing the frictional resistance when the female connector F rotates with respect to the female holder 1 so that the displacement operation can be performed smoothly. Further, a total of four retaining pieces 9 are formed on the opening edge of the other end of the female holder 1 so as to project radially inwardly at intervals of about 90 degrees. Each retaining piece 9 and the rib 8 have a phase difference of about 45 degrees. A punching hole 10 for punching is formed on the seat surface 7 on the axially rear surface of both retaining pieces 9 corresponding to the formation range of the retaining pieces.

かくして、雌ホルダ１全体は軸方向に沿って開閉可能な金型によって成形される。 Thus, the entire female holder 1 is formed by a mold that can be opened and closed along the axial direction.

＜雌コネクタＦ＞
図４乃至図６に示すように、雌コネクタＦは合成樹脂製の雌コネクタハウジング１１を有している。雌コネクタハウジング１１は、ハウジング本体１２と雌ホルダ１の雌コネクタ装着部６への取付けのためのフランジ部１３と一対の作動翼部１４とを備えて一体に形成されている。 <Female connector F>
As shown in FIGS. 4 to 6, the female connector F has a female connector housing 11 made of synthetic resin. The female connector housing 11 is integrally formed with a housing body 12, a flange portion 13 for attaching the female holder 1 to the female connector mounting portion 6, and a pair of operating blade portions 14.

ハウジング本体１２はブロック状に形成され、内部には雌端子金具４７を収容可能な複数のキャビティ１５が形成されている。雌端子金具４７にはそれぞれ電線Ｗが接続され、雌コネクタハウジング１１から導出された後に、雌ホルダ１を通して外部に引き出されている。ハウジング本体１２の外面にはロックアーム１６が撓み可能に形成され、雌雄コネクタＦ，Ｍが正規に嵌合すると、雄コネクタＭに係止して雌雄コネクタＦ，Ｍを嵌合状態にロックする。 The housing body 12 is formed in a block shape, and a plurality of cavities 15 that can accommodate the female terminal fittings 47 are formed therein. An electric wire W is connected to each of the female terminal fittings 47 and is led out through the female holder 1 after being led out from the female connector housing 11. A lock arm 16 is formed on the outer surface of the housing body 12 so as to be deflectable. When the male and female connectors F and M are properly fitted, the male and female connectors F and M are locked in a fitted state.

図５に示すように、ハウジング本体１２の後端部には円盤状に形成された基盤部１７が一体に設けられている。この基盤部１７はハウジング本体１２より大きく形成され、ロックアーム１６を成形する領域には抜き孔１８が開口している（図６参照）。また、基盤部１７の背面には各キャビティ１５の一端側が開口している。 As shown in FIG. 5, a base portion 17 formed in a disc shape is integrally provided at the rear end portion of the housing body 12. The base portion 17 is formed larger than the housing body 12, and a hole 18 is opened in a region where the lock arm 16 is formed (see FIG. 6). In addition, one end side of each cavity 15 is opened on the back surface of the base portion 17.

フランジ部１３は、基盤部１７の周面における後縁部に同心の円盤状をなして張り出し形成されている。フランジ部１３の厚みは、雌コネクタ装着部６において抜け止め片９と座面７との間の間隔よりやや薄めに形成されている。また、フランジ部１３は雌コネクタ装着部６よりも小径に形成され、雌コネクタＦが雌ホルダ１に対し後述する初期位置にあるときには、雌コネクタＦは雌コネクタ装着部６内に保持された状態で、フランジ部１３の平面方向に沿った所定範囲内で変位可能となっている。 The flange portion 13 is formed so as to protrude in a concentric disk shape at the rear edge portion of the peripheral surface of the base portion 17. The thickness of the flange portion 13 is formed slightly thinner than the distance between the retaining piece 9 and the seat surface 7 in the female connector mounting portion 6. Further, the flange portion 13 is formed to have a smaller diameter than the female connector mounting portion 6, and the female connector F is held in the female connector mounting portion 6 when the female connector F is in an initial position described later with respect to the female holder 1. Thus, it can be displaced within a predetermined range along the plane direction of the flange portion 13.

図５、図６に示すように、各フランジ部１３には略９０度間隔毎に切欠き凹所１９が切欠き形成されている。各切欠き凹所１９は雌ホルダ１の各抜け止め片９と適合するように形成され、このことによってフランジ部１３を各抜け止め片９との干渉を回避しつつ座面７に対して回動可能な状態で当接させることができる。以下、このときの雌ホルダ１に対する雌コネクタハウジング１１の位置を組み付け位置と言う（図２Ａ参照）。 As shown in FIGS. 5 and 6, a notch recess 19 is formed in each flange portion 13 at intervals of approximately 90 degrees. Each notch recess 19 is formed so as to be fitted with each retaining piece 9 of the female holder 1, and thereby the flange portion 13 is rotated with respect to the seat surface 7 while avoiding interference with each retaining piece 9. The contact can be made in a movable state. Hereinafter, the position of the female connector housing 11 with respect to the female holder 1 at this time is referred to as an assembly position (see FIG. 2A).

雌コネクタＦは、この組み付け位置から図２における時計周りに略４５度回動させられて初期位置にて保持される（図２Ｂ参照）。この初期位置においては、雌コネクタＦは、図４に示すように、雌ホルダ１の他端側から略同軸で突出した状態となって、雌雄コネクタＦ，Ｍの嵌合が可能となる。初期位置においては、フランジ部１３が各抜け止め片９と係止しているため、雌コネクタＦは雌ホルダ１に対して抜け止めされた状態で保持されるとともに、座面７とフランジ部１３との当接により、雌雄コネクタＦ，Ｍの嵌合時の抵抗を受け止めることができる。 The female connector F is rotated approximately 45 degrees clockwise in FIG. 2 from this assembly position and held at the initial position (see FIG. 2B). In this initial position, as shown in FIG. 4, the female connector F protrudes substantially coaxially from the other end of the female holder 1 so that the male and female connectors F and M can be fitted. In the initial position, since the flange portion 13 is engaged with each retaining piece 9, the female connector F is held in a state of being retained from the female holder 1, and the seat surface 7 and the flange portion 13 are retained. , The resistance when the male and female connectors F and M are fitted can be received.

図５等に示すように、基盤部１７の周面において前縁側（ハウジング本体１２側）には前記した一対の作動翼部１４が突出形成されている。両作動翼部１４は、延出方向に沿って真っ直ぐに延びる側縁１４Ａを有し、これら側縁１４Ａは基盤部１７の中心軸を略通過するようにして形成されている。図５に示すように、両作動翼部１４のうち真っ直ぐに延びた側縁と反対側の側縁は先端部側から付け根部側に向けて徐々に幅広となるように形成されている。両作動翼部１４の先端部には均一幅をもって作動部２０が形成されている。雌コネクタハウジング１１が雌ホルダ１に装着された状態では、両作動部２０の全体を含む作動翼部１４の先端部が雌ホルダ１から径方向外方へ突出している。また、図２Ｂに示すように、雌コネクタハウジング１１が初期位置にある状態では、両作動翼部１４は両逃がし溝５と対応して位置している。 As shown in FIG. 5 and the like, the above-described pair of operating blade portions 14 are formed to protrude on the front edge side (housing body 12 side) on the peripheral surface of the base portion 17. Both working blade portions 14 have side edges 14 </ b> A that extend straight along the extending direction, and these side edges 14 </ b> A are formed so as to substantially pass through the central axis of the base portion 17. As shown in FIG. 5, the side edge opposite to the side edge that extends straight out of the two operating wings 14 is formed to gradually widen from the tip side toward the root side. An operating portion 20 is formed with a uniform width at the tip of both operating blade portions 14. In a state where the female connector housing 11 is mounted on the female holder 1, the distal end portion of the operating blade portion 14 including the entire operating portion 20 protrudes radially outward from the female holder 1. Further, as shown in FIG. 2B, in the state where the female connector housing 11 is in the initial position, both the operating blade portions 14 are positioned corresponding to the both escape grooves 5.

雌コネクタＦが雌ホルダ１に対して初期位置から図示反時計方向へ略９０度回転した位置は、後に詳述するが、雌雄コネクタＦ，Ｍが正規に嵌合する嵌合完了位置（図２Ｃ参照）である。同位置では、フランジ部１３が各抜け止め片９と係止しており、雌コネクタＦが雌ホルダ１に対して抜け止めされた状態のままである。しかし、雌コネクタＦが雌ホルダ１に対して嵌合完了位置からさらに図示反時計回りに略４５度回転した位置は、雌コネクタＦが雌ホルダ１に対して分離する分離位置である（図２Ｄ参照）。同位置では、フランジ部１３が各抜け止め片９の間、つまり各切欠き凹所１９に適合して位置し、雌コネクタＦが雌ホルダ１から軸方向外方へ分離可能である。このように、雌コネクタＦ側においては、初期位置と分離位置との間に組み付け位置を設定している。つまり、雌コネクタＦは組み付け位置から初期位置へと回動された後、この変位方向とは逆方向へ変位されて分離位置に至るようにしている。換言すれば、雌コネクタＦから導出された各電線Ｗが一旦ねじられた後に、このねじれを解く方向にねじられることになるようにしてあるため、初期位置から分離位置に至るまでの間に電線Ｗがねじられる程度が緩和されていることになる。 The position where the female connector F is rotated approximately 90 degrees counterclockwise from the initial position with respect to the female holder 1 will be described in detail later, but the fitting completion position where the male and female connectors F and M are properly fitted (FIG. 2C). Reference). At the same position, the flange portion 13 is engaged with each retaining piece 9, and the female connector F remains in the retaining state with respect to the female holder 1. However, the position where the female connector F is further rotated approximately 45 degrees counterclockwise from the fitting completion position with respect to the female holder 1 is a separation position where the female connector F is separated from the female holder 1 (FIG. 2D). reference). At the same position, the flange portion 13 is positioned between the retaining pieces 9, that is, in conformity with the notch recesses 19, and the female connector F can be separated from the female holder 1 in the axially outward direction. Thus, on the female connector F side, the assembly position is set between the initial position and the separation position. That is, after the female connector F is rotated from the assembly position to the initial position, the female connector F is displaced in a direction opposite to the displacement direction to reach the separation position. In other words, since each electric wire W led out from the female connector F is once twisted, the electric wire W is twisted in the direction of unwinding the twist. The degree to which W is twisted is relaxed.

＜雄ホルダ２＞
図１に示すように、雄ホルダ２は合成樹脂材にて雌ホルダ１よりは短かい円筒形状に形成されている。雄ホルダ２の一端側（雌コネクタＦと対向する側）には径方向外方へ一対の取付け片２１が突出形成されている。図８等に示すように、両取付け片２１にはねじ締め用の穴２２が開口し、図示しない機器側への固定が可能である。また、雄ホルダ２の周面において両取付け片２１の付け根部分にはそれぞれ窓孔２３が開口している（図１６（Ａ）、（Ｂ）参照）。両窓孔２３は雄コネクタＭに設けられた一対の保持爪２４を係止させることで、雄コネクタＭを雄ホルダ２に対し初期位置に保持させることができる。 <Male holder 2>
As shown in FIG. 1, the male holder 2 is formed of a synthetic resin material in a cylindrical shape that is shorter than the female holder 1. A pair of attachment pieces 21 are formed to protrude radially outward from one end side of the male holder 2 (side facing the female connector F). As shown in FIG. 8 and the like, both attachment pieces 21 have screw tightening holes 22 that can be fixed to a device (not shown). Further, window holes 23 are opened at the base portions of the mounting pieces 21 on the peripheral surface of the male holder 2 (see FIGS. 16A and 16B). The two window holes 23 can hold the male connector M in the initial position with respect to the male holder 2 by engaging a pair of holding claws 24 provided in the male connector M.

一方、図１０、図１１に示すように、雄ホルダ２の他端側の開口縁には一対の係止突起２５が径方向内向きに突出形成されている。両係止突起２５を結ぶ軸線は両取付け片２１を結ぶ軸線から周方向へ僅かにずれるような設定としてある。 On the other hand, as shown in FIGS. 10 and 11, a pair of locking projections 25 are formed in the opening edge on the other end side of the male holder 2 so as to protrude radially inward. The axis connecting both locking projections 25 is set so as to be slightly shifted in the circumferential direction from the axis connecting both mounting pieces 21.

図８、図１６（Ａ）、（Ｂ）に示すように、雄ホルダ２の一端側（雌コネクタＦと対向する側）の開口縁における両窓孔２３と対応する位置には、雄コネクタＭの両作動翼部１４を次述するカム面２６へと導入するための導入部２７が、それぞれ軸方向に沿いつつ両窓孔２３の奥縁に至るまでの範囲に亘って凹み形成されている。図１６（Ａ）、（Ｂ）に示すように、両導入部２７は窓孔２３の全体、つまり窓孔２３全深さ範囲及び全幅範囲に亘って連通するようにして形成されている。換言すれば、両導入部２７は窓孔の周方向への幅と同幅をもって形成され、かつその一開口縁が雄ホルダ２の外周面とほぼ面一をなすようにして形成されている。したがって、窓孔２３を成形する際には、導入部２７を形成するための軸方向に沿って進退自在な金型と、雄ホルダ２の外周面を成形する軸方向に沿って進退自在な金型とが径方向で密着状態で擦れ合い、このことによって方形状に開口する窓孔を成形することができるようにしている。 As shown in FIG. 8, FIG. 16 (A), (B), the male connector M is located at a position corresponding to the two window holes 23 on the opening edge of one end side (side facing the female connector F) of the male holder 2. Introduced portions 27 for introducing the two operating blade portions 14 into the cam surface 26 described below are recessed along the axial direction to reach the inner edges of the two window holes 23. . As shown in FIGS. 16A and 16B, both the introduction portions 27 are formed so as to communicate with the entire window hole 23, that is, over the entire depth range and the entire width range of the window hole 23. In other words, both the introduction portions 27 are formed to have the same width as that of the window hole in the circumferential direction, and one opening edge thereof is formed so as to be substantially flush with the outer peripheral surface of the male holder 2. Therefore, when the window hole 23 is formed, a mold that can advance and retract along the axial direction for forming the introduction portion 27 and a metal that can freely advance and retract along the axial direction for forming the outer peripheral surface of the male holder 2. The mold is rubbed in a close contact state in the radial direction so that a window hole opening in a square shape can be formed.

また、図８、図１６（Ａ）、（Ｂ）に示すように、雄ホルダ２の内周面を所定角度範囲に亘って除肉することで、一対のカム面２６（誘導手段）が形成されている。両カム面２６には一定ピッチ毎に微小な段差面２６Ａが、カム面２６の全範囲に亘って形成されており、各段差は導入部２７側へ上るように形成されている。両カム面２６は雄コネクタＭの作動翼部１４と全範囲に亘って摺接することで、軸方向に沿った雌雄コネクタＦ，Ｍの嵌合動作と連動して雌雄コネクタＦ，Ｍに回転運動を行わせるためのものである。両カム面２６は導入部２７の奥端部を始端として奥方へ向けて螺旋状に延出し、略１３５度の角度範囲に亘って形成されている。また、カム面２６の終端部は、軸方向に沿って雄ホルダ２の他端側の開口縁に開口するようにして形成された導出部２８に連続しており、雌コネクタＦの両作動翼部１４が両導出部２８を通して雄ホルダ２の外部へ通過可能となっている。 Also, as shown in FIGS. 8, 16A, and 16B, a pair of cam surfaces 26 (guide means) are formed by removing the inner peripheral surface of the male holder 2 over a predetermined angle range. Has been. On both cam surfaces 26, minute step surfaces 26A are formed over the entire range of the cam surface 26 at every constant pitch, and each step is formed so as to rise to the introduction portion 27 side. Both cam surfaces 26 are in sliding contact with the working blade portion 14 of the male connector M over the entire range, so that the male and female connectors F and M rotate in conjunction with the fitting operation of the male and female connectors F and M along the axial direction. It is for letting you do. Both cam surfaces 26 extend spirally from the back end of the introduction portion 27 toward the back, and are formed over an angle range of about 135 degrees. Further, the end portion of the cam surface 26 is continuous with the lead-out portion 28 formed so as to open to the opening edge on the other end side of the male holder 2 along the axial direction. The portion 14 can pass through the lead-out portions 28 to the outside of the male holder 2.

図７等に示すように、両カム面２６は雄ホルダ２を軸方向に沿う一方側から見たときに、同方向に対面するようにして形成されている。したがって、両カム面２６は軸方向に進退する金型によって成形可能である。結局のところ、両導出部２８および両係止突起２５を含み、雄ホルダ２全体は軸方向に開閉可能な金型によって成形可能となっている。 As shown in FIG. 7 and the like, both cam surfaces 26 are formed so as to face in the same direction when the male holder 2 is viewed from one side along the axial direction. Therefore, both cam surfaces 26 can be formed by a mold that advances and retreats in the axial direction. After all, the male holder 2 as a whole, including both lead-out portions 28 and both locking projections 25, can be molded by a mold that can be opened and closed in the axial direction.

＜雄コネクタＭ＞
雄コネクタＭは合成樹脂製の雄コネクタハウジング２９を有している。図１２乃至図１４に示すように、雄コネクタハウジング２９は本体部３０と、その前部に一体に形成されたフード部３１とから構成されている。本体部３０の内部には複数のキャビティ３２が形成され、内部には雄端子金具４６が抜け止めされた状態で収容されている。雄端子金具４６には電線Ｗが接続され、電線Ｗは雄コネクタハウジング２９から導出され、さらに雄ホルダ２を通して外部に引き出されている。 <Male connector M>
The male connector M has a male connector housing 29 made of synthetic resin. As shown in FIGS. 12 to 14, the male connector housing 29 includes a main body portion 30 and a hood portion 31 formed integrally with the front portion thereof. A plurality of cavities 32 are formed inside the main body 30, and the male terminal fitting 46 is housed in a state in which the male terminal fitting 46 is prevented from coming off. An electric wire W is connected to the male terminal fitting 46, and the electric wire W is led out from the male connector housing 29 and further drawn out through the male holder 2.

図１３、図１４に示すように、フード部３１の外形は雄ホルダ２内に略同心で差し込み可能な略二段円筒形状に形成されている。一方、図１２に示すように、フード部３１の内側は正面視で方形状の中空空間Ｋとなっており、内部には各雄端子金具４６の先端部が並列状態で突出するとともに、雌コネクタハウジング１１を回り止めされた状態で嵌合させうる。したがって、雌雄コネクタＦ，Ｍが嵌合した状態で、雌コネクタＦが回動すれば、雄コネクタＭもまた一体となって同方向に回動することになる。 As shown in FIGS. 13 and 14, the outer shape of the hood portion 31 is formed in a substantially two-stage cylindrical shape that can be inserted substantially concentrically into the male holder 2. On the other hand, as shown in FIG. 12, the inside of the hood portion 31 is a rectangular hollow space K when viewed from the front, and the distal end portions of the male terminal fittings 46 are projected in parallel inside the female connector. The housing 11 can be fitted in a state of being prevented from rotating. Therefore, if the female connector F rotates in a state where the male and female connectors F and M are fitted, the male connector M also rotates integrally in the same direction.

図１２に示すように、フード部３１の開口面の全辺には前方へ向けてラッパ状をなすテーパ状の誘い込み面３３が形成されている。このため、雌雄コネクタＦ，Ｍの嵌合の開始にあたり、雌雄コネクタＦ，Ｍの中心軸がずれていても、この誘い込み面３３によって雌コネクタＦを同心となる位置に誘い込むことができる。また、図１２に示すように、フード部３１内の壁面のうち雌コネクタハウジング１１のロックアーム１６に対応する壁面には一対のガイドリブ３４が設けられている。両ガイドリブ３４はフード部３１の開口面から軸方向に沿って平行に延び、雌雄コネクタＦ，Ｍの嵌合の案内をするとともに、雌コネクタＦの上下反転姿勢での誤嵌合を規制する役割りを果たす。また、図１２に示すように、両ガイドリブ３４の間には係止受け部３５が形成され、図１７に示すように、雌雄コネクタＦ，Ｍが正規に嵌合したときにロックアーム１６に係止可能となっている。 As shown in FIG. 12, a tapered guiding surface 33 having a trumpet shape is formed on the entire side of the opening surface of the hood portion 31. Therefore, when the male and female connectors F and M are started to be fitted, even if the center axes of the male and female connectors F and M are displaced, the female connector F can be guided to a concentric position by the guiding surface 33. As shown in FIG. 12, a pair of guide ribs 34 is provided on the wall surface in the hood portion 31 corresponding to the lock arm 16 of the female connector housing 11. Both guide ribs 34 extend in parallel along the axial direction from the opening surface of the hood portion 31, guide the fitting of the male and female connectors F, M, and regulate the erroneous fitting of the female connector F in the upside down posture. Fulfill. As shown in FIG. 12, a locking receiving portion 35 is formed between the guide ribs 34. As shown in FIG. 17, when the male and female connectors F and M are properly fitted, the locking arm 16 is engaged. It is possible to stop.

フード部３１の外周面であって、本体部３０寄りの縁部（後縁部）には、一対の保持爪２４が設けられている。両保持爪２４は、雄ホルダ２に対し雄コネクタハウジング２９を初期位置に保持しておく役割を果たすためのものである。図１２、図１４に示すように、両保持爪２４はフード部３１の中心軸を挟んで略対称の位置に配されている。両保持爪２４はフード部３１の外周面から一旦径方向外方へ立ち上がる脚部３６を有している。脚部３６は、図１４に示すように、後面視で立ち上がり端側へ向けて末広がりとなる扇形状に形成されている。両脚部３６の立ち上がり端部からは斜め前方へ向けてアーム部３７が片持ち状に延出しており、フード部３１の外周面から遠ざかる方向へ撓み可能となっている。両アーム部３７は、その先端の位置がフード部３１の前端を越えてさらに前方に至る長さをもって形成されている。また、両アーム部３７の先端の内側には爪部３８が突出形成されており、図１６（Ｂ）に示すように、雄ホルダ２の窓孔２３に係止可能であり、係止状態では爪部３８の先端は雄ホルダ２の導入部２７内に臨むようにしてある。さらに、爪部３８の側面のうち雄コネクタＭが初期位置から嵌合完了位置へ回動する際に窓孔２３の開口縁に突き当てられる側に対向する側面はテーパ状の撓み案内面３９となっている（図１２、図１４参照）。このことによって、雄コネクタＭが初期位置から嵌合完了位置へ向けて回動しようとしたときに作用するトルクにより、爪部３８が円滑に窓孔２３から外部へ脱することができる。 A pair of holding claws 24 are provided on the outer peripheral surface of the hood portion 31 and on the edge portion (rear edge portion) near the main body portion 30. Both holding claws 24 serve to hold the male connector housing 29 in the initial position with respect to the male holder 2. As shown in FIGS. 12 and 14, both holding claws 24 are arranged at substantially symmetrical positions across the central axis of the hood portion 31. Both holding claws 24 have leg portions 36 that rise from the outer peripheral surface of the hood portion 31 to the outside in the radial direction. As shown in FIG. 14, the leg portion 36 is formed in a fan shape that expands toward the rising end side in a rear view. An arm portion 37 extends in a cantilevered manner from the rising end portion of both leg portions 36 in a diagonally forward direction, and can be bent in a direction away from the outer peripheral surface of the hood portion 31. Both arm portions 37 are formed so that the positions of the tips thereof extend beyond the front end of the hood portion 31 and further forward. Further, a claw portion 38 is formed on the inner side of the tip of both arm portions 37 and can be locked to the window hole 23 of the male holder 2 as shown in FIG. The tip of the claw portion 38 faces the introduction portion 27 of the male holder 2. Further, of the side surfaces of the claw portion 38, the side surface facing the side abutted against the opening edge of the window hole 23 when the male connector M rotates from the initial position to the fitting completion position is formed with a tapered bending guide surface 39. (See FIGS. 12 and 14). As a result, the claw portion 38 can be smoothly detached from the window hole 23 by the torque acting when the male connector M tries to rotate from the initial position toward the fitting completion position.

なお、雄コネクタＭが雄ホルダ２に対して初期位置に保持されているときは、雌ホルダ１に対して初期位置に保持されている雌コネクタＦと正対して嵌合可能となる位置関係となっている。 When the male connector M is held at the initial position with respect to the male holder 2, the positional relationship is such that the female connector F can be mated with the female connector F held at the initial position with respect to the female holder 1. It has become.

図１２に示すように、フード部３１の開口縁部にはフード部３１の中心軸を挟んで一対の通過凹所４０が開口している。この通過凹所４０は、雄コネクタＭを雄ホルダ２の内部へ組み込む際及び雄ホルダ２から分離される際に、両係止突起２５を通過させるためのものである。係止突起２５と通過凹所４０とが適合するときの、雄ホルダ２に対する雄コネクタＭの位置が組み付け位置であり（図９Ａ参照）、また同時に分離位置でもある（図９Ｄ参照）。 As shown in FIG. 12, a pair of passage recesses 40 are opened at the opening edge portion of the hood portion 31 with the central axis of the hood portion 31 interposed therebetween. The passage recess 40 is for allowing both locking projections 25 to pass when the male connector M is assembled into the male holder 2 and separated from the male holder 2. The position of the male connector M with respect to the male holder 2 when the locking projection 25 and the passage recess 40 are fitted is the assembly position (see FIG. 9A), and at the same time the separation position (see FIG. 9D).

一方、図１３に示すように、フード部３１の外周面において、軸方向に関する片側半分（後半部：本体部３０寄りの半分）の領域は、両保持爪２４の脚部３６が形成されている幅領域を除いて除肉されている。これにより、フード部３１の後半部は小径部４１となり、前半部は大径部４２となっている。また、図１４に示すように、この除肉により脚部３６が形成された幅領域の両側面は小径部４１の外周面から立ち上がる立ち上がり面４３となっている。この立ち上がり面４３のうち一方の面はフード部３１の全長に亘って設けられて通過凹所４０に連続して形成されているのに対し、他方の面の形成範囲は大径部４２との境界面に至る長さ範囲に留まっている。両立ち上がり面４３は、雄コネクタＭが初期位置および分離位置において雄ホルダ２の両係止突起２５の側面に当接して雄コネクタＭの一方向への回り止め機能を果たす。 On the other hand, as shown in FIG. 13, in the outer peripheral surface of the hood portion 31, the leg portions 36 of the two holding claws 24 are formed in the region on one side half (the rear half portion: the half near the main body portion 30) in the axial direction. It has been thinned except for the width region. Thus, the rear half of the hood part 31 is a small diameter part 41 and the front half is a large diameter part 42. Further, as shown in FIG. 14, both side surfaces of the width region where the leg portions 36 are formed by this thinning are rising surfaces 43 rising from the outer peripheral surface of the small diameter portion 41. One of the rising surfaces 43 is provided over the entire length of the hood portion 31 and is formed continuously with the passage recess 40, whereas the other surface has a range of formation with the large-diameter portion 42. It remains in the length range up to the boundary surface. The two rising surfaces 43 perform a function of preventing the male connector M from rotating in one direction by contacting the side surfaces of the locking protrusions 25 of the male holder 2 when the male connector M is in the initial position and the separation position.

図１４に示すように、大径部４２と小径部４１との境界面となる段差面は、保持爪２４の両脚部３６を境として一対の規制面４４となっている。この規制面４４はフード部３１は周方向に沿って（軸方向と直交する方向に沿って）形成され、周方向に沿って形成される範囲は略９０度の角度範囲に亘っている。規制面４４は雄コネクタＭが初期位置から嵌合完了位置に至るまでの間は、雄ホルダ２の両係止突起２５に当接することで、雄コネクタＭが雄ホルダ２から後方へ抜けないようにしている。 As shown in FIG. 14, the stepped surface that becomes the boundary surface between the large diameter portion 42 and the small diameter portion 41 is a pair of regulating surfaces 44 with both leg portions 36 of the holding claw 24 as a boundary. In this restricting surface 44, the hood portion 31 is formed along the circumferential direction (along the direction orthogonal to the axial direction), and the range formed along the circumferential direction is an angle range of approximately 90 degrees. The restriction surface 44 is in contact with both locking projections 25 of the male holder 2 until the male connector M reaches the fitting completion position from the initial position so that the male connector M does not come out of the male holder 2 backward. I have to.

図１３に示すように、規制面４４には、フード部３１の開口面側へ向けて傾斜するテーパ状の移行面４５が連続しており、それぞれは通過凹所４０に臨んでいる。移行面４５の周方向に関する形成範囲は、略４５°の角度範囲に亘っており、雄コネクタＭが嵌合完了位置と分離位置とを回動する間の範囲に対応している。 As shown in FIG. 13, a taper-shaped transition surface 45 that is inclined toward the opening surface side of the hood portion 31 is continuous with the regulation surface 44, and each faces the passage recess 40. The formation range of the transition surface 45 in the circumferential direction extends over an angle range of approximately 45 °, and corresponds to the range during which the male connector M rotates between the fitting completion position and the separation position.

雄コネクタＭが雄ホルダ２に対し初期位置にある状態から、図９Ｂに示す反時計周りに略９０度回動した位置が嵌合完了位置である（図９Ｃ参照）。このように、雌雄コネクタＦ，Ｍを初期位置から嵌合完了位置にまで回動させる間の嵌合ストロークは、雌雄コネクタＦ，Ｍを正規の嵌合状態（ロックアーム１６が雄コネクタハウジング２９の係止受け部３５に係止する状態）に至らせることができるように設定されている。雄コネクタＭが嵌合完了位置にあるときには、雄ホルダ２の係止突起２５が規制面４４を通過して移行面４５の始端部に位置している。嵌合完了位置から雄コネクタＭがさらに略４５度回動すると、雄コネクタＭは雌コネクタＦと正規嵌合したまま分離位置に至る（図９Ｄ参照）。分離位置に至るまでの間は、雄コネクタＭが移行面４５の形成範囲を通過するため、雄コネクタＭは雄ホルダ２に対し回動と軸方向への後退動作を行う結果、雄ホルダ２の係止突起２５は立ち上がり面４３に係止して通過凹所４０と適合する位置に位置決めされる。その後、雌コネクタＦが取付けられた部品（図示しない）が雄コネクタＭが取付けられた機器側に正規に装着されると、雌雄コネクタＦ，Ｍは嵌合状態のままさらに軸方向へ変位し、図１８に示すように、雄ホルダ２を突き抜けて電線Ｗによって空中に保持される。 The position where the male connector M is rotated approximately 90 degrees counterclockwise as shown in FIG. 9B from the state where the male connector M is at the initial position with respect to the male holder 2 is the fitting completion position (see FIG. 9C). As described above, the fitting stroke during the rotation of the male and female connectors F and M from the initial position to the fitting completion position is such that the male and female connectors F and M are in a proper fitting state (the lock arm 16 is in the male connector housing 29). It is set so that it can be brought into a state of being locked to the locking receiving portion 35. When the male connector M is in the fitting completion position, the locking projection 25 of the male holder 2 passes through the restriction surface 44 and is positioned at the start end of the transition surface 45. When the male connector M further rotates approximately 45 degrees from the fitting completion position, the male connector M reaches the separation position while being normally fitted with the female connector F (see FIG. 9D). Since the male connector M passes through the formation range of the transition surface 45 until reaching the separation position, the male connector M rotates and retreats in the axial direction with respect to the male holder 2. The locking protrusion 25 is positioned at a position that is locked to the rising surface 43 and matches the passage recess 40. After that, when a part (not shown) to which the female connector F is attached is properly mounted on the device side to which the male connector M is attached, the male and female connectors F and M are further displaced in the axial direction while being fitted, As shown in FIG. 18, it penetrates the male holder 2 and is held in the air by the electric wire W.

次に、上記のように構成された本実施例の作用効果を具体的に説明する。雌コネクタＦを雌ホルダ１に組み付ける場合には、雌コネクタＦを雌ホルダ１に対し組み付け位置にする（図２Ａ参照）。すなわち、フランジ部１３の各切欠き凹所１９を雌ホルダ１の抜け止め片９に適合させた状態で、雌コネクタ装着部６内に嵌め入れてフランジ部１３を座面７に当接させる。その後、雌コネクタＦを雌ホルダ１に対し図示反時計回りに略４５度回動させて初期位置に至らせる（図２Ｂ参照）。この間、フランジ部１３は各リブ８上を摺接するため、比較的軽い操作力で雌コネクタＦを初期位置に移動させることができる。初期位置においては、フランジ部１３が各抜け止め片９に係止しているため、雌コネクタＦは雌ホルダ１から軸方向外方へ抜け止めされた状態にあり、かつ座面７とフランジとの当接により、軸方向内方へ押し込まれてしまうこともない。なお、雌コネクタＦが雌ホルダ１に組み付けられた状態では、前述したように、フランジ部１３が構成する平面に沿って所定範囲内を自由にずれ動くことができる。 Next, the function and effect of the present embodiment configured as described above will be specifically described. When the female connector F is assembled to the female holder 1, the female connector F is set to the assembling position with respect to the female holder 1 (see FIG. 2A). That is, in a state where each notch recess 19 of the flange portion 13 is fitted to the retaining piece 9 of the female holder 1, the flange portion 13 is brought into contact with the seat surface 7 by being fitted into the female connector mounting portion 6. Thereafter, the female connector F is rotated approximately 45 degrees counterclockwise in the figure with respect to the female holder 1 to reach the initial position (see FIG. 2B). During this time, since the flange portion 13 is in sliding contact with each rib 8, the female connector F can be moved to the initial position with a relatively light operating force. In the initial position, since the flange portion 13 is locked to each retaining piece 9, the female connector F is retained from the female holder 1 in the axially outward direction, and the seat surface 7 and the flange It is not pushed inward in the axial direction by the contact. In the state where the female connector F is assembled to the female holder 1, as described above, it can freely move within a predetermined range along the plane formed by the flange portion 13.

一方、雄コネクタＭを雄ホルダ２に組み付ける場合には、雄コネクタＭを雄ホルダ２の後面側において組み付け位置に位置合わせする（図９Ａ参照）。すなわち、両保持爪２４のアーム部３７を拡開させつつ雄ホルダ２の外周面を挟み付け、かつフード部３１の両通過凹所４０を係止突起２５に適合させる。そして、この組み付け位置のままフード部３１を軸方向に沿って押し込む。この後、雄コネクタＭを雄ホルダ２に対し図９における反時計周りに略１３５度回動させる。この回動動作はその途中から、係止突起２５が規制面４４に摺接するようになり、このことによって雄コネクタＭは雄ホルダ２に対し軸方向に関して位置決めがなされたままで回転がなされる。そして、雄コネクタＭが雄ホルダ２に対して略１３５度回動した時点で両係止突起２５は立ち上がり面４３に当接することで、これ以上の回動が規制される。これと同時に、両保持爪２４の爪部３８が窓孔２３内に嵌まり込んで係止するため、雄コネクタＭは初期位置において回り止めされた状態で保持される（図９Ｂ参照）。 On the other hand, when the male connector M is assembled to the male holder 2, the male connector M is aligned with the assembly position on the rear surface side of the male holder 2 (see FIG. 9A). That is, the outer peripheral surface of the male holder 2 is sandwiched while the arm portions 37 of both holding claws 24 are expanded, and both the passage recesses 40 of the hood portion 31 are fitted to the locking projections 25. And the hood part 31 is pushed in along an axial direction with this assembly position. Thereafter, the male connector M is rotated approximately 135 degrees counterclockwise in FIG. 9 with respect to the male holder 2. In the middle of this turning operation, the locking projection 25 comes into sliding contact with the regulating surface 44, whereby the male connector M is rotated while being positioned with respect to the male holder 2 in the axial direction. Then, when the male connector M rotates approximately 135 degrees with respect to the male holder 2, both the locking projections 25 come into contact with the rising surface 43, whereby further rotation is restricted. At the same time, the claw portions 38 of both holding claws 24 are fitted and locked in the window hole 23, so that the male connector M is held in a state of being prevented from rotating at the initial position (see FIG. 9B).

上記のようにしてホルダに取付けられた雌雄のコネクタは、部品あるいは機器に取付けられる（部品あるいは機器にホルダを取付けた後に雌雄のコネクタを組付けるようにしてもよい）。そして、雌雄のコネクタを向き合わせたまま、これらの嵌合軸線に沿って部品を機器に取付ける作業を行う。 The male and female connectors attached to the holder as described above are attached to parts or equipment (the male and female connectors may be assembled after the holder is attached to the parts or equipment). And the operation | work which attaches components to an apparatus along these fitting axis lines is performed, facing the male and female connectors.

すると、まず、作動翼部１４が雄ホルダ２内に進入する前に、雌コネクタハウジング１１の先端部が雄コネクタＭのフード部３１の入口に適合する。その場合に、雌雄コネクタＦ，Ｍが正対しておらず、互いの中心軸線が多少の芯ずれを生じていたとしても、雌コネクタＦは雌ホルダ１に対して平面方向に沿った遊動が許容されていることから、フード部３１の開口面に形成された各誘い込み面３３の誘導作用によって雌雄コネクタＦ，Ｍ間の芯ずれを吸収して正対させることができる。 Then, first, the front end portion of the female connector housing 11 is fitted to the inlet of the hood portion 31 of the male connector M before the operating wing portion 14 enters the male holder 2. In this case, even if the male and female connectors F and M are not facing each other and the center axis of each other is slightly misaligned, the female connector F is allowed to move along the plane direction with respect to the female holder 1. Therefore, the misalignment between the male and female connectors F and M can be absorbed and brought into direct alignment by the guiding action of each guiding surface 33 formed on the opening surface of the hood portion 31.

上記の正対状態の後に、雌雄コネクタＦ，Ｍが浅く嵌合すると、両作動翼部１４の作動部２０が導入部２７を通して雄ホルダ２内に進入して両保持爪２４の爪部３８に当接する。これにより、爪部３８は外方へ後退させられ、窓孔２３に対する引っ掛かりが浅くなる（図１６（Ｂ）参照）。雌雄のコネクタの嵌合がさらに進行すると、作動部２０がカム面２６の始端部に至り、さらに嵌合力が加えられるとカム面２６による案内を受けて、嵌合状態にある雌雄コネクタＦ，Ｍに対し嵌合完了位置へ向けての回転トルクが作用する。これにより、両保持爪２４の爪部３８に形成された撓み案内面３９が窓孔２３の孔縁に摺接することで、爪部３８は窓孔２３から抜け出るため、この時点において、雌雄コネクタＦ，Ｍの回動動作が許容される。 When the male and female connectors F and M are shallowly fitted after the above facing state, the operating parts 20 of the two operating wing parts 14 enter the male holder 2 through the introduction part 27 and enter the claw parts 38 of the holding claws 24. Abut. Thereby, the nail | claw part 38 is retracted outward and the catch with respect to the window hole 23 becomes shallow (refer FIG.16 (B)). When the male and female connectors are further fitted, the operating portion 20 reaches the start end portion of the cam surface 26. When further fitting force is applied, the operation is received by the cam surface 26 and the male and female connectors F and M in the fitted state are received. On the other hand, a rotational torque toward the fitting completion position acts. As a result, the bending guide surface 39 formed on the claw portions 38 of the both holding claws 24 is in sliding contact with the hole edge of the window hole 23 so that the claw portion 38 comes out of the window hole 23. At this time, the male and female connectors F , M is allowed to rotate.

これ以後、雌雄コネクタＦ，Ｍの嵌合の進行に連動して作動部２０がカム面２６に沿って摺接するため、雌雄コネクタＦ，Ｍは嵌合動作と共に回動動作がなされる。そして、雌雄コネクタＦ，Ｍが共に初期位置から略９０度回動すると、雌コネクタＦのロックアーム１６が雄コネクタＭの係止受け部３５に係止して雌雄コネクタＦ，Ｍが正規嵌合状態となる。すなわち、雌雄コネクタＦ，Ｍは共に嵌合完了位置に至る（図２Ｃ、図９Ｃ状態）。 Thereafter, the operating portion 20 slides along the cam surface 26 in conjunction with the progress of the fitting of the male and female connectors F and M, so that the male and female connectors F and M are rotated together with the fitting operation. When both the male and female connectors F and M are rotated approximately 90 degrees from the initial position, the lock arm 16 of the female connector F is locked to the locking receiving portion 35 of the male connector M, and the male and female connectors F and M are properly fitted. It becomes a state. That is, both the male and female connectors F and M reach the fitting completion position (the state shown in FIGS. 2C and 9C).

なお、雌コネクタＦ側においては、初期位置から嵌合完了位置へ至るまでの間に、つまり、初期位置から略４５度回動した時点でフランジ部１３の各切欠き凹所１９が雌ホルダ１の抜け止め片９に適合するが、この時点では雌雄コネクタＦ，Ｍの嵌合中であるため、雌ホルダ１から抜け落ちてしまうことはない。また、雄コネクタＭに関して、初期位置から嵌合完了位置に至るまでの間は、両係止突起２５が規制面４４に当接した状態が継続するため、雄ホルダ２に対して軸方向への変位はない。また、嵌合完了位置においては、図９Ｃに示すように、導出部２８と通過凹所４０とは周方向に関して整合した状態となる。 On the female connector F side, each notch recess 19 of the flange portion 13 is formed in the female holder 1 from the initial position to the fitting completion position, that is, when the female connector F is rotated approximately 45 degrees from the initial position. However, since the male and female connectors F and M are being fitted at this time, they will not fall out of the female holder 1. Further, with respect to the male connector M, the state in which both the locking projections 25 are in contact with the restriction surface 44 continues from the initial position to the mating completion position. There is no displacement. Moreover, in the fitting completion position, as shown to FIG. 9C, the derivation | leading-out part 28 and the passage recessed part 40 will be in the state matched regarding the circumferential direction.

雌雄コネクタＦ，Ｍが嵌合完了位置に至った後も、機器側に対する部品の装着作業が進行すると、雌ホルダ１が相対的に雄ホルダ２内を軸方向に沿って進む。このため、両作動翼部１４の作動部２０がカム面２６上を引き続いて摺接しつつ進行するため、雌雄コネクタＦ，Ｍは正規嵌合状態のまま回動動作のみが進行する。 Even after the male and female connectors F and M reach the mating completion position, when the mounting operation of components on the device side proceeds, the female holder 1 relatively moves along the axial direction in the male holder 2. For this reason, since the action | operation part 20 of both the action wing | blade parts 14 advances on the cam surface 26, and advances, the male-and-female connectors F and M advance only rotation operation with a normal fitting state.

前述したように、雄コネクタＭが嵌合完了位置に至ると、両係止突起２５の当接位置が規制面４４から移行面４５へと移行する。このため、雌ホルダ１が相対的に雄ホルダ２内を軸方向に沿って進み、同時に雌雄コネクタＦ，Ｍの回動が進むと、両係止突起２５は移行面４５の傾斜に沿って摺接するため、雄コネクタＭは徐々に後退して雄ホルダ２から軸方向外方へ突出するようになる。そして、雌雄コネクタＦ，Ｍが嵌合完了位置から略４５度回動すると、雌雄コネクタＦ，Ｍは共に分離位置に至る（図２Ｄ、図９Ｄ状態）。分離位置では、両作動部２０が雄ホルダ２におけるカム面２６の終端部に至るとともに、立ち上がり面４３が係止突起２５にそれぞれ当接することでこれ以上の回動が規制されるため、雌コネクタＦ側では各切欠き凹所１９が各抜け止め片９に適合した位置に保持され、雄コネクタＭ側では両係止突起２５が通過凹所４０に適合する。このように、分離位置においては、雌雄いずれのコネクタもホルダから軸方向へ分離可能な状態となる。 As described above, when the male connector M reaches the mating completion position, the contact position of both the locking projections 25 shifts from the regulation surface 44 to the transition surface 45. For this reason, when the female holder 1 relatively moves along the axial direction in the male holder 2 and at the same time the rotation of the male and female connectors F and M proceeds, both the locking projections 25 slide along the inclination of the transition surface 45. In order to make contact, the male connector M gradually retracts and protrudes outward in the axial direction from the male holder 2. Then, when the male and female connectors F and M are rotated approximately 45 degrees from the mating completion position, both the male and female connectors F and M reach the separation position (states in FIGS. 2D and 9D). In the separated position, both operating parts 20 reach the end of the cam surface 26 in the male holder 2 and the rising surfaces 43 abut against the locking projections 25 to restrict further rotation, so that the female connector On the F side, each notch recess 19 is held at a position suitable for each retaining piece 9, and on the male connector M side, both locking projections 25 fit in the passage recess 40. Thus, in the separation position, both male and female connectors can be separated from the holder in the axial direction.

したがって、上記の状態から部品が機器側に装着される位置までさらに軸方向に移動すると、雄コネクタＭは雌コネクタＦによって雄ホルダ２から軸方向外方へ突き出される。また、雄コネクタＭに嵌合している雌コネクタＦも雌ホルダ１から解離し、さらには両作動部２０が雄ホルダの導出部２８を通過することで、雄ホルダから軸方向外方へと分離する。その結果、雌雄コネクタＦ，Ｍは電線Ｗによって宙に浮いた状態で支持される。かくして、機器に対する部品の装着作業が完了する。 Therefore, when the component further moves in the axial direction from the above state to the position where the component is mounted on the device side, the male connector M is protruded outward from the male holder 2 by the female connector F. Further, the female connector F fitted to the male connector M is also detached from the female holder 1, and further, both the operating parts 20 pass through the male holder lead-out part 28, so that the male holder moves outward in the axial direction. To separate. As a result, the male and female connectors F and M are supported by the electric wires W in a floating state. Thus, the component mounting operation for the device is completed.

なお、雌コネクタが雄ホルダから突き出されるときには、両係止突起２５は雌ホルダに設けられた逃がし溝５に適合するため、図１８に示すように、雌ホルダの先端側は雄ホルダから軸方向外方へ突出した状態となる。 When the female connector is protruded from the male holder, both the locking projections 25 fit into the relief grooves 5 provided on the female holder, so that the distal end side of the female holder is pivoted from the male holder as shown in FIG. It will be in the state of protruding outward.

本実施例の効果は次の通りである。
（１）雌雄コネクタＦ，Ｍは各ホルダから分離されて宙に浮いた状態で支持されるため、両コネクタに車両の振動が直接には伝達されないから、雌雄の端子金具間に悪影響が及ぶことはない。
（２）雌コネクタＦは、初期位置において雌ホルダ１の座面７に沿った平面方向にずれ動くことができるため、部品を機器側に組み付ける際に雌雄コネクタＦ，Ｍの芯ずれがあったとしても、雄コネクタＭのフード部３１に形成された誘い込み面３３の誘導作用によって芯ずれを吸収して雌雄コネクタＦ，Ｍの嵌合動作を円滑に行わせることができる。
（３）雌雄コネクタＦ，Ｍは雌雄のホルダに対し、初期位置と嵌合完了位置との間を回動動作によって変位させるようにしている。このような回動形式に代えて、仮に軸方向へのスライド動作によって行う場合には、ホルダが大型化してしまうが、本実施例ではかかる懸念がない。
（４）本実施例では、雌コネクタＦ側において、初期位置と分離位置との間に組み付け位置が設定されている。したがって、雌コネクタＦに接続された電線Ｗは、一旦、初期位置側へ略４５度ねじられた後に、ねじれの中立位置である組み付け位置を経由してここから略９０度ねじられる。仮に、組み付け位置、初期位置、嵌合完了位置、分離位置を、この記載順で一方向に設定した場合には、電線Ｗは最終的に略１３５度ねじられてしまうが、本実施例では電線Ｗのねじり量が小さくて済むため、作業中の電線Ｗの負担を軽減することができる、という効果も得られる。
（５）雌ホルダ１と雄ホルダ２は、これらを成形する金型が径方向に進退するいわゆるスライド型を必要とせず、軸方向にのみ開閉する簡易な構造のもので済む。したがって、雌雄のホルダ１、２を安価に製造することができる。 The effect of the present embodiment is as follows.
(1) Since the male and female connectors F and M are separated from the holders and supported in a floating state, the vibrations of the vehicle are not directly transmitted to both connectors. There is no.
(2) Since the female connector F can move in the plane direction along the seating surface 7 of the female holder 1 at the initial position, the male and female connectors F and M are misaligned when the components are assembled to the equipment side. Even so, the misalignment can be absorbed by the guiding action of the guide surface 33 formed on the hood portion 31 of the male connector M, and the male and female connectors F and M can be smoothly engaged.
(3) The male and female connectors F and M are displaced with respect to the male and female holders by a rotation operation between the initial position and the fitting completion position. In place of such a rotation type, if the sliding operation is performed in the axial direction, the holder becomes large, but there is no such concern in this embodiment.
(4) In this embodiment, on the female connector F side, an assembly position is set between the initial position and the separation position. Therefore, the electric wire W connected to the female connector F is once twisted approximately 45 degrees toward the initial position side, and then twisted approximately 90 degrees from here through the assembly position which is a neutral position of the twist. If the assembly position, initial position, mating completion position, and separation position are set in one direction in this description order, the wire W will eventually be twisted by approximately 135 degrees. Since the amount of twisting of W can be small, an effect that the burden of the electric wire W during work can be reduced is also obtained.
(5) The female holder 1 and the male holder 2 do not require a so-called slide mold in which a mold for molding them advances and retreats in the radial direction, and may have a simple structure that opens and closes only in the axial direction. Therefore, the male and female holders 1 and 2 can be manufactured at low cost.
