Description

本発明は、例えば自動車に搭載し、ハウジング同士の嵌合時の施錠機構を有すると共に、ハウジング同士の完全嵌合を確認できる確認手段を備えたコネクタに関するものである。   The present invention relates to a connector that is mounted on, for example, an automobile, has a locking mechanism when fitting housings, and includes a confirmation unit that can confirm complete fitting between housings.

自動車の電気配線等に使用される従来のコネクタは、例えば特許文献１に示されているように、接続端子を収容した一対のハウジング同士を結合及び解除するための手段を備え、この手段にはその結合の完全嵌合状態を係止保持する慣性ロック、クリックロック等のロック手段を設けて、結合の完全嵌合を確保するようにしている。そして、結合作業の際には、このロック構造により、弾性係合に伴う音又は手指の感触等によりコネクタの完全嵌合を確認している。   A conventional connector used for electric wiring of an automobile, for example, as shown in Patent Document 1, includes a means for coupling and releasing a pair of housings that house connection terminals. Locking means such as an inertia lock and a click lock for locking and holding the fully-fitted state of the coupling is provided to ensure the complete fitting of the coupling. In the coupling operation, the connector is confirmed to be completely fitted by a sound associated with the elastic engagement or the feeling of fingers with this lock structure.

特開２００３−１５７９３１号公報JP 2003-157931 A

近年、自動車メーカーでは、燃費向上対策としてハイブリッドシステム、エアコン等に高電圧・電流を採用推進中であるが、これらの高電圧・電流回路では、通電用のコネクタの半嵌合や誤解除が発生した場合に、その接点接触部にスパークが生じて、その際のスパーク温度も高くなることから、コネクタ溶損等の問題が発生する懸念がある。   In recent years, automobile manufacturers are promoting the adoption of high voltage and current for hybrid systems, air conditioners, etc. as measures to improve fuel efficiency. However, these high voltage and current circuits cause half-fitting and erroneous release of energizing connectors. In such a case, a spark is generated at the contact point of the contact, and the spark temperature at that time is also increased.

また、従来のコネクタの完全嵌合確認は、上述のように慣性ロック、クリックロックなどの音や感触等の作業者の感覚に大きく依存しており、作業者による誤認があると、車両走行中における不時のコネクタ解除の危険性が生ずる虞れもある。これを回避するために、完全嵌合の保証を作業者及び第三者が容易に確認し得る機構が強く要望されている。   In addition, the complete fitting confirmation of the conventional connector largely depends on the operator's feeling such as inertia lock, click lock and the like as described above. There is also a possibility that the risk of unintentional connector release will occur. In order to avoid this, there is a strong demand for a mechanism that allows workers and third parties to easily confirm the guarantee of complete fitting.

本発明の目的は、上述の問題点を解消し、外部から第三者が目視で確認できるようにして不完全嵌合を防止するコネクタを提供することにある。   An object of the present invention is to provide a connector that solves the above-mentioned problems and prevents incomplete fitting by allowing a third party to visually confirm from the outside.

A locking claw to be mated is provided in the first housing, and the first and second housings in which the locking levers of the locking lever are engaged with the locking claw are locked by a slide holder. A connector that can confirm the fully fitted state by visually observing the position of the slide holder , wherein the slide holder is attached to the second housing so as to be movable back and forth along a guide; Before the second housing is fitted, the slide holder is prevented from advancing by a first stopper attached to the locking lever, and the first housing is fitted by fitting the first and second housings together. A fixed cam contact provided on the slide moves the control arm of the slide holder to release the locking by the first stopper , and the tongue piece protruding forward by the advance of the slide holder in the fully fitted state by fixing the movement of the locking lever by being inserted presses the locking lever to said first housing side between the peripheral wall and the locking lever of the second housing lock of the completely fitted state In addition , it is possible to visually confirm that the slide holder is at an appropriate movement position.

本発明に係るコネクタによれば、確認手段が完全嵌合時において機能することにより目視によりその状態を確認でき、その状態をロックすると共に完全嵌合状態であることが保証される。   According to the connector according to the present invention, the state of the checking means can be confirmed by visual observation when it functions at the time of complete fitting, and the state is locked and it is guaranteed that the state is completely fitted.

本発明を図示の実施例に従って詳細に説明する。   The invention will be described in detail according to the embodiments shown in the drawings.

In addition, insertion connection terminals are built in the plug portion 12, and their connection ends 15 protrude from the rear portion of the flange portion 11. Note that a bolt hole 16 for fixing the first housing 1 to a panel or the like is formed in the flange portion 11.

第２のハウジング２の上面には、完全嵌合状態を機械的にロックして確保するスライドホルダ２１が取り付けられており、このスライドホルダ２１は後述する機構により両ハウジング１、２の完全嵌合状態においてのみ、図１の状態から図２の状態に示すように、第２のハウジング２上を適正移動位置まで前進可能とされている。   A slide holder 21 that mechanically locks and secures the fully fitted state is attached to the upper surface of the second housing 2, and this slide holder 21 is completely fitted between the housings 1 and 2 by a mechanism that will be described later. Only in the state, as shown in the state of FIG. 1 from the state of FIG. 1, the second housing 2 can be advanced to an appropriate movement position.

第２のハウジング２の前半部には、第１のハウジング１のプラグ部１２と嵌合し、内部に受用接続端子を内挿したソケット部２２が形成され、その前方に相手側接続端子をそれぞれ受け入れる挿入孔２３が形成されている。ソケット部２２を囲む周壁２４の上面中央部は上方に膨出され、この膨出部の内側に幅広の逆凹溝２５が形成されている。この凹溝２５の後方に連ねて、第２のハウジング２の後半部の上面に、左右一対の起立壁２６が立設されている。更に、周壁２４の膨出部の後縁部分にスライドホルダ２１の進入を許容する矩形状の切欠部２７が形成され、この切欠部２７の奥所に半円形の凹部２８が設けられている。   A socket portion 22 is formed in the front half of the second housing 2 so as to be fitted with the plug portion 12 of the first housing 1 and into which the receiving connection terminal is inserted. An insertion hole 23 for receiving is formed. A central portion of the upper surface of the peripheral wall 24 surrounding the socket portion 22 bulges upward, and a wide reverse concave groove 25 is formed inside the bulged portion. A pair of left and right upright walls 26 are erected on the upper surface of the rear half of the second housing 2 so as to be connected to the rear of the concave groove 25. Further, a rectangular notch 27 that allows the slide holder 21 to enter is formed at the rear edge portion of the bulging portion of the peripheral wall 24, and a semicircular recess 28 is provided at the back of the notch 27.

図３はスライドホルダ２１を取り外し、周壁２４の一部を切欠した斜視図を示し、逆凹溝２５、起立壁２６内の中央部分に、第１のハウジング１に対するロック用の略長板状の錠止レバー２９が、前後方向の中間部の左右一対の支柱３０を支点としてシーソー状態に支持されている。この錠止レバー２９の先端部には錠止鉤３１が形成され、更に後端部の押下操作端３２は左右一対の弾性片３３に支えられ、錠止レバー２９の水平体勢が維持されるようになっている。 FIG. 3 is a perspective view in which the slide holder 21 is removed and a part of the peripheral wall 24 is cut away. The reverse concave groove 25 and a central portion in the standing wall 26 are formed in a substantially long plate shape for locking the first housing 1. The locking lever 29 is supported in a seesaw state with a pair of left and right support columns 30 in the middle in the front-rear direction as fulcrums. A locking rod 31 is formed at the front end of the locking lever 29, and the pressing operation end 32 at the rear end is supported by a pair of left and right elastic pieces 33 so that the horizontal posture of the locking lever 29 is maintained. It has become.

錠止レバー２９の前半部の中途部分に、スライドホルダ２１の前進を阻止する爪形の左右一対の第１ストッパ３４が、斜面を前側に向けて両側に突設され、上面にはこの前半部の上昇時にスライドホルダ２１の前進を阻止する第２ストッパ３５がその斜面を前方に向けて突設されている。左右一対の起立壁２６の内面に、スライドホルダ２１を摺動自在に装着する左右一対の水平ガイドレール３６が形成され、これらの水平ガイドレール３６の後端部に左右一対の抜止用ストッパ３７が形成されている。   A pair of claw-shaped left and right first stoppers 34 that prevent the slide holder 21 from moving forward are provided in the middle part of the front half of the locking lever 29 so as to protrude on both sides with the inclined surface facing the front side, and the front half is provided on the upper surface. A second stopper 35 that prevents the slide holder 21 from moving forward when the slide holder 21 is raised is provided with its inclined surface facing forward. A pair of left and right horizontal guide rails 36 for slidably mounting the slide holder 21 is formed on the inner surfaces of the pair of left and right standing walls 26, and a pair of left and right retaining stoppers 37 are provided at the rear ends of the horizontal guide rails 36. Is formed.

図４に示すように、スライドホルダ２１は起立壁２６の内幅に適合した横幅を有し、両側面に左右一対の水平案内条片２１ａが形成されており、この水平案内条片２１ａは起立壁２６の水平ガイドレール３６に前後方向に摺動自在に嵌合するようになっている。   As shown in FIG. 4, the slide holder 21 has a lateral width adapted to the inner width of the upright wall 26, and a pair of left and right horizontal guide strips 21a are formed on both side surfaces. The horizontal guide rail 36 of the wall 26 is slidably fitted in the front-rear direction.

スライドホルダ２１の前面の下段部から、左右方向に弾性変形する左右一対の制御アーム２１ｂが前方に向けて突設されている。両制御アーム２１ｂの先端部の上半部分には、錠止レバー２９の第１ストッパ３４に突き当たってスライドホルダ２１の前進を規制をする左右一対の内向きの衝合爪２１ｃが形成されている。また、両制御アーム２１ｂを外側に曲げて弾性変形させることで、両衝合爪２１ｃの突き当たりを解除するために、両制御アーム２１ｂの先端部の下半部分には、プラグ部１２の固定カム接触子１４に、それぞれ接する内向きにテーパ状のカム面２１ｄを備えた左右一対の三角カム２１ｅが形成されている。   A pair of left and right control arms 21b that elastically deform in the left-right direction protrude from the lower step portion of the front surface of the slide holder 21 toward the front. A pair of left and right inward abutting claws 21 c that abut against the first stopper 34 of the locking lever 29 and restrict the forward movement of the slide holder 21 are formed in the upper half of the tip portions of both control arms 21 b. . In addition, in order to release the abutment of both abutting claws 21c by bending both control arms 21b outward and elastically deforming them, a fixed cam of the plug portion 12 is provided at the lower half portion of the tip portions of both control arms 21b. The contactor 14 is formed with a pair of left and right triangular cams 21e each having an inwardly tapered cam surface 21d in contact therewith.

なお図示の実施例では、衝合爪２１ｃと三角カム２１ｅは内向きに形成されて、両三角カム２１ｅにより制御アーム２１ｂが外方に押し拡げられ、この押し拡げに伴い衝合爪２１ｃが第１ストッパ３４から離脱されるようになっている。しかし、両三角カム２１ｅ及び両衝合爪２１ｃが外向きに形成され、かつ錠止レバー２９の第１ストッパ３４も位置的にこれに対応させて配置することにより、制御アーム２１ｂが逆に内方へと押し狭められることで、同様の作用が得られるようにしてもよい。   In the illustrated embodiment, the abutting claw 21c and the triangular cam 21e are formed inward, and the control arm 21b is pushed outward by the triangular cams 21e. 1 is separated from the stopper 34. However, both the triangular cams 21e and the two abutting claws 21c are formed outwardly, and the first stopper 34 of the locking lever 29 is also disposed corresponding to the position, so that the control arm 21b A similar action may be obtained by being narrowed in the direction.

更に、スライドホルダ２１には前面の中段部から前方に向けて、錠止レバー２９の第２ストッパ３５と対応する舌片２１ｆが突設されていて、錠止レバー２９の前半部が上昇した際に、この舌片２１ｆの先端が第２ストッパ３５に突き当たってスライドホルダ２１の前進が規制されるようになっている。更に、スライドホルダ２１の上段部前面の中央から前方に向けて、切欠部２７の凹部２８と嵌合する同じ半円状の凸部２１ｇが突設されている。   Further, the slide holder 21 has a tongue piece 21f corresponding to the second stopper 35 of the locking lever 29 projecting forward from the middle step on the front surface, and the front half of the locking lever 29 is raised. Further, the tip of the tongue piece 21f abuts against the second stopper 35 so that the advance of the slide holder 21 is restricted. Furthermore, the same semicircular convex part 21g which fits into the concave part 28 of the notch part 27 protrudes from the center of the front surface of the upper stage part of the slide holder 21 to the front.

第１、第２のハウジング１、２同士の結合前の状態では、図５に示すようにスライドホルダ２１は第２のハウジング２の後部に後退している。この状態では、図５に示すように制御アーム２１ｂの両衝合爪２１ｃが錠止レバー２９の第１のストッパ３４に衝合していて、スライドホルダ２１は前進不能である。
ここで第１、第２のハウジング１、２を嵌合させると、図６に示すようにプラグ部１２の両固定カム接触子１４が、スライドホルダ２１の制御アーム２１ｂにおける三角カム２１ｅのカム面２１ｄにそれぞれ当接される。更に、第１、第２のハウジング１、２の嵌合を進めると、両固定カム接触子１４と両三角カム２１ｅと摺動して、両制御アーム２１ｂが外側に押し広げられ、両衝合爪２１ｃが両側の第１ストッパ３４から外れて、スライドホルダ２１は前進可能となる。 In a state before the first and second housings 1 and 2 are coupled to each other, the slide holder 21 is retracted to the rear part of the second housing 2 as shown in FIG. In this state, as shown in FIG. 5, both abutting claws 21 c of the control arm 21 b abut against the first stopper 34 of the locking lever 29, and the slide holder 21 cannot advance.
Here, when the first and second housings 1 and 2 are fitted, the fixed cam contacts 14 of the plug portion 12 are connected to the cam surface of the triangular cam 21e in the control arm 21b of the slide holder 21, as shown in FIG. 21d, respectively. Further, when the fitting of the first and second housings 1 and 2 is advanced, both the fixed cam contacts 14 and both the triangular cams 21e slide, both control arms 21b are pushed outward, and both collisions occur. The claw 21c is disengaged from the first stoppers 34 on both sides, and the slide holder 21 can advance.

更に嵌合が進み、第１のハウジング１のプラグ部１２と第２のハウジング２のソケット部２２とを嵌合させたハウジング１、２同士の完全嵌合状態では、図６に示すように錠止レバー２９の前端部の錠止鉤３１が弾性片３３の弾力に抗して、プラグ部１２の錠止爪１３を乗り越えて係合する。この完全嵌合はクリック手段による聴覚でも確認できる。即ち、錠止レバー２９の錠止鉤３１が錠止爪１３を乗り越えた時に「カチン」という音を発し、その乗り越えが不十分、不適切な場合にはこの音を発しないからである。 When the fitting further proceeds and the housings 1 and 2 are completely fitted together, in which the plug portion 12 of the first housing 1 and the socket portion 22 of the second housing 2 are fitted together, the lock is formed as shown in FIG. The locking rod 31 at the front end of the locking lever 29 gets over and engages with the locking claw 13 of the plug portion 12 against the elasticity of the elastic piece 33. This complete fitting can also be confirmed by hearing by clicking means. That is, when the locking lever 31 of the locking lever 29 gets over the locking claw 13, it makes a “click” sound, and when it is insufficient and inappropriate, it does not make this sound.

なお、この完全嵌合状態においては、図７の断面図に示すように第１、第２のハウジング１、２にそれぞれ収納されている接続端子４１、４２同士が嵌合し、コネクタの電気的接続がなされる。   In this fully fitted state, as shown in the sectional view of FIG. 7, the connection terminals 41 and 42 housed in the first and second housings 1 and 2 are fitted to each other, and the electrical connection of the connector A connection is made.

この完全嵌合状態において、スライドホルダ２１を前進させると、図８に示すように舌片２１ｆが錠止レバー２９の第２ストッパ３５の上面と第２のハウジング２の周壁２４の膨出部内面との間に進入して、錠止レバー２９のシーソー動を阻止し、第１のハウジング１における錠止爪１３と、これに係合する錠止レバー２９の錠止鉤３１とをその係合状態をロックする。この場合に、スライドホルダ２１は周囲部材との接触により、自然には動き得ず、スライドホルダ２１はハウジング１、２同士間の完全嵌合での本来の完全嵌合保証機能を発揮する。
また、スライドホルダ２１が前進しても第１ストッパ３４から解放されて嵌合状態が不完全な場合には、錠止レバー２９の先端は錠止爪１３に乗り上げた状態なり、舌片２１ｆの先端は第２ストッパ３５に突き当たりスライドホルダ２１はそれ以上の前進が不可能となる。 When the slide holder 21 is moved forward in this completely fitted state, the tongue piece 21f is brought into contact with the upper surface of the second stopper 35 of the locking lever 29 and the inner surface of the bulging portion of the peripheral wall 24 of the second housing 2 as shown in FIG. To prevent the seesaw movement of the locking lever 29 and to engage the locking claw 13 in the first housing 1 and the locking rod 31 of the locking lever 29 engaged therewith. Lock state. In this case, the slide holder 21 cannot move naturally due to contact with the surrounding members, and the slide holder 21 exhibits the original complete fitting guarantee function in the complete fitting between the housings 1 and 2.
In addition, even if the slide holder 21 moves forward, if it is released from the first stopper 34 and the fitting state is incomplete, the tip of the locking lever 29 rides on the locking claw 13, and the tongue piece 21f The leading end abuts against the second stopper 35 and the slide holder 21 cannot advance further.

スライドホルダ２１が前進して本来の完全嵌合保証機能を発揮したときは、スライドホルダ２１が適正移動位置まで移動しているので、図２に示すように凸部２１ｇと凹部２８とが相互に嵌合して、スライドホルダ２１の前進完了を表示し、目視によりこの完全嵌合状態を確認できる。 When the slide holder 21 is exerted the original full engagement assurance function to move forward, because the slide holder 21 is moved to the proper movement position, to each other and the convex portion 21g and the concave portion 28 as shown in FIG. 2 The completion of advancement of the slide holder 21 is displayed by fitting, and this complete fitting state can be confirmed visually.

また、両ハウジング１、２同士を嵌合しても未だ完全嵌合に至らずに、錠止レバー２９の錠止鉤３１が錠止爪１３により押し上げられている状態では、錠止レバー２９の前半部の上昇に伴って第２ストッパ３５も上昇しているので、スライドホルダ２１を前進させても、舌片２１ｆの先端が第２ストッパ３５に突き当たって、スライドホルダ２１は適正移動位置まで前進できず、スライドホルダ２１の前進不足を表示する。   Further, even when the housings 1 and 2 are fitted together, the locking lever 31 of the locking lever 29 is not fully engaged yet and the locking lever 31 is pushed up by the locking claw 13. Since the second stopper 35 is also raised with the rise of the front half, even if the slide holder 21 is advanced, the tip of the tongue piece 21f abuts against the second stopper 35, and the slide holder 21 advances to the proper movement position. Inability to display the slide holder 21 indicating insufficient advancement.

また、嵌合した第１、第２ハウジング１、２同士を離脱させる際には、スライドホルダ２１を強く押し戻すことにより後退させ、錠止レバー２９に対するスライドホルダ２１によるロックを解除する。次いで、錠止レバー２９の後端部の押下操作端３２を両弾性片３３の弾力に抗して押し下げることにより、錠止レバー２９の前半部を上昇させて、錠止レバー２９の前端部の錠止鉤３１を第１のハウジング１のプラグ部１２の錠止爪１３から解離し、両ハウジング１、２同士を引き離せば図１の状態に戻る。   Further, when the fitted first and second housings 1 and 2 are separated from each other, the slide holder 21 is retracted by pushing it back strongly, and the lock by the slide holder 21 is released. Next, the push-down operation end 32 at the rear end of the lock lever 29 is pushed down against the elasticity of both elastic pieces 33 to raise the front half of the lock lever 29, so that the front end of the lock lever 29 If the locking rod 31 is disengaged from the locking claw 13 of the plug portion 12 of the first housing 1 and the housings 1 and 2 are separated from each other, the state shown in FIG.

なお、相互に嵌合する凸部２１ｇと凹部２８は複数組あってもよい。また、その形状も半円状に限らず、三角状、四角状、その他の適宜の形状を選択できる。また、スライドホルダ２１の移動の確認は、実施例以外にも種々の方式を採用することができる。   Note that there may be a plurality of pairs of the convex portion 21g and the concave portion 28 that are fitted to each other. Further, the shape is not limited to a semicircular shape, and a triangular shape, a square shape, and other appropriate shapes can be selected. Further, various methods other than the embodiment can be adopted for confirming the movement of the slide holder 21.

図９は実施例２の要部斜視図であり、スライドホルダ２１の移動確認の他の例を示し、実施例１と同一の符号は同じ部材を表している。   FIG. 9 is a perspective view of a main part of the second embodiment, showing another example of confirming the movement of the slide holder 21, and the same reference numerals as those in the first embodiment represent the same members.

スライドホルダ２１の舌片２１ｆ上に、前後方向の断面が台形状の突起２１ｈが設けられており、凸部２１ｇは形成されていない。一方、第１のハウジング１のソケット部２２の切欠部２７の奥部には、前後方向に平行に２本の条溝１７、１７が切り込まれ、その間に可撓片１８が形成されている。また可撓片１８には、スライドホルダ２１の突起２１ｈと対応する孔部１９が設けられている。   A projection 21h having a trapezoidal cross section in the front-rear direction is provided on the tongue piece 21f of the slide holder 21, and the convex portion 21g is not formed. On the other hand, two strip grooves 17 and 17 are cut into the back of the notch 27 of the socket portion 22 of the first housing 1 in parallel to the front-rear direction, and a flexible piece 18 is formed therebetween. . The flexible piece 18 is provided with a hole 19 corresponding to the protrusion 21 h of the slide holder 21.

なお、可撓片１８の前端下面には、図１０に示すようにスライドホルダ２１の突起２１ｈの斜面により可撓片１８が持ち上げられ易いように斜面が形成され、孔部１９のスライドホルダ２１側も突起２１ｈを後方に引き出す場合に、抜け出し易いように斜面とされている。   Note that a slope is formed on the lower surface of the front end of the flexible piece 18 so that the flexible piece 18 can be easily lifted by the slope of the protrusion 21h of the slide holder 21, as shown in FIG. Also, when the protrusion 21h is pulled out rearward, it is inclined so that it can be easily pulled out.

このような構成において、図１１に示すようにスライドホルダ２１を前進させると、突起２１ｈが可撓片１８に当接し可撓片１８を持ち上げる。更にそのまま、スライドホルダ２１を前進させると、突起２１ｈは孔部１９に嵌合し、可撓片１８は元の位置に復元する。   In such a configuration, when the slide holder 21 is advanced as shown in FIG. 11, the protrusion 21 h comes into contact with the flexible piece 18 and lifts the flexible piece 18. When the slide holder 21 is further advanced as it is, the protrusion 21h is fitted into the hole 19, and the flexible piece 18 is restored to the original position.

この突起２１ｈの孔部１９への嵌合時には、「カチン」という音を発すると共に、突起２１ｈが孔部１９内に嵌入していることを目視で確認することができる。特に、スライドホルダ２１の色を第１、第２のハウジング１、２の色と異ならせておけば、目視による確認は更に容易となる。   When the projection 21h is fitted into the hole 19, it is possible to visually confirm that the projection 21h is inserted into the hole 19 while making a “click” sound. In particular, if the color of the slide holder 21 is different from the colors of the first and second housings 1 and 2, the visual confirmation is further facilitated.

第１、第２のハウジング１、２同士の解離時に際して、スライドホルダ２１を後進させるには、スライドホルダ２１を後方に強く押し出すと、突起２１ｈの後縁が可撓片１８を持ち上げることにより、突起２１ｈと孔部１９との嵌合が外れるので、実施例１と同様に錠止レバー２９に対するスライドホルダ２１のロックを解除できる。   In order to move the slide holder 21 backward when the first and second housings 1 and 2 are dissociated, when the slide holder 21 is pushed backward strongly, the rear edge of the protrusion 21h lifts the flexible piece 18, Since the fitting between the projection 21h and the hole 19 is released, the lock of the slide holder 21 with respect to the locking lever 29 can be released as in the first embodiment.

実施例１のハウジング同士を分離した状態の斜視図である。It is a perspective view of the state where the housings of Example 1 were separated. ハウジング同士を結合した状態の斜視図である。It is a perspective view in the state where housings were combined. スライドホルダを取り外した状態の第２のハウジングの一部を切欠した斜視図である。It is the perspective view which notched a part of 2nd housing of the state which removed the slide holder. スライドホルダの斜視図である。It is a perspective view of a slide holder. 第２のハウジングの一部を切欠した斜視図である。It is the perspective view which notched a part of 2nd housing. ハウジング同士の完全嵌合状態の一部を切欠した斜視図である。It is the perspective view which notched a part of the perfect fitting state of housings. 完全嵌合状態におけるスライドホルダを前進させる直前の断面図である。It is sectional drawing just before advancing the slide holder in a perfect fitting state. 完全嵌合状態におけるスライドホルダを前進させた斜視図である。It is the perspective view which advanced the slide holder in a perfect fitting state. 実施例２の第２のハウジングの斜視図である。6 is a perspective view of a second housing of Embodiment 2. FIG. ソケット部の要部断面図である。It is principal part sectional drawing of a socket part. ハウジング同士の完全嵌合状態でスライドホルダを前進させた斜視図である。It is the perspective view which advanced the slide holder in the perfect fitting state of housings.
