　またこのとき、コンタクト１３に取り付けられたラック１９も後方へ移動するため、ラック１９と噛み合うピニオン２０は時計回りに回転し、ピニオン２０と噛み合うピニオン２１は反時計回りに回転する。そして、ピニオン２１が反時計回りに回転することで、ピニオン２１が取り付けられたハンドル５１も反時計回りに回転する。 At this time, since the rack 19 attached to the contact 13 also moves rearward, the pinion 20 that meshes with the rack 19 rotates clockwise, and the pinion 21 that meshes with the pinion 20 rotates counterclockwise. As the pinion 21 rotates counterclockwise, the handle 51 to which the pinion 21 is attached also rotates counterclockwise.
　ハンドル５１が反時計回りに回転すると、リンク５８の上脚部５８１によって支持アーム５６の係合突片５６２が後向きに押圧される。これにより、支持アーム５６は、軸６４の周りで反時計回りに回転する。このとき、軸６３に軸支された可動バー５３も支持アーム５６とともに前側へ移動する。ここで、リンク５９は、下脚部５９０が上脚部５９１とハンドル軸６５とを結ぶ線分よりも後側にあるときは、ハンドル５１の回転によって上側へ移動する。 When the handle 51 is rotated counterclockwise, the engagement leg 562 of the support arm 56 is pressed backward by the upper leg portion 581 of the link 58. Thereby, the support arm 56 rotates counterclockwise around the shaft 64. At this time, the movable bar 53 supported by the shaft 63 also moves forward together with the support arm 56. Here, when the lower leg portion 590 is behind the line segment connecting the upper leg portion 591 and the handle shaft 65, the link 59 moves upward by the rotation of the handle 51.
　またこのとき、リンク５９の上脚部５９１が、可動バー５３のストッパ片５３１を上向きに押圧する。つまり、可動バー５３は、加圧ばね（図示せず）によって軸６３の周りで反時計回りの弾性力を受けながら、リンク５９の上脚部５９１から時計回りに押圧される。 At this time, the upper leg portion 591 of the link 59 presses the stopper piece 531 of the movable bar 53 upward. That is, the movable bar 53 is pressed clockwise from the upper leg portion 591 of the link 59 while receiving a counterclockwise elastic force around the shaft 63 by a pressure spring (not shown).
　そして、ケース１０を図２に示す位置まで押し込むと、コンタクト１３の第１接触部４４が給電ソケット４３の筒内の所定位置まで差し込まれ、第２接触部４３０と電気的に接続される。 Then, when the case 10 is pushed to the position shown in FIG. 2, the first contact portion 44 of the contact 13 is inserted to a predetermined position in the cylinder of the power supply socket 43 and is electrically connected to the second contact portion 430.
　このとき、コンタクト１３がさらに後方へ移動することでリンク１４も軸１７の周りで時計回りに回転し、さらに軸１６が溝１１４内を後方へ移動することで、ロック部材１５も後方へ移動する。またこのとき、ロック部材１５が、ねじりばねからの弾性力によって時計回りに回転し、ロック部材１５の引掛部１５２が解除部材２６の段部２６１に引っ掛かる。 At this time, when the contact 13 further moves rearward, the link 14 also rotates clockwise around the shaft 17, and when the shaft 16 moves rearward in the groove 114, the lock member 15 also moves rearward. . At this time, the lock member 15 is rotated clockwise by the elastic force from the torsion spring, and the hook portion 152 of the lock member 15 is hooked on the step portion 261 of the release member 26.
　さらにこのとき、コンタクト１３によってマイクロスイッチ２２がオンになり、マイクロスイッチ２２から出力される駆動信号によってソレノイド装置２４が起動し、ピン２４１が前方に伸びた状態になる。この状態では、解除釦２３を押し込むことができないため、解除釦２３が誤って押されるのを防止することができる。 Further, at this time, the micro switch 22 is turned on by the contact 13, the solenoid device 24 is activated by the drive signal output from the micro switch 22, and the pin 241 extends forward. In this state, since the release button 23 cannot be pushed in, it is possible to prevent the release button 23 from being pushed by mistake.
　またこのとき、コンタクト１３に取り付けられたラック１９も後方へ移動するため、ラック１９と噛み合うピニオン２０も時計回りに回転し、ピニオン２０と噛み合うピニオン２１も反時計回りに回転する。そして、ピニオン２１が反時計回りに回転することで、ピニオン２１が取り付けられたハンドル５１も反時計回りに回転する。 At this time, since the rack 19 attached to the contact 13 also moves rearward, the pinion 20 that meshes with the rack 19 also rotates clockwise, and the pinion 21 that meshes with the pinion 20 also rotates counterclockwise. As the pinion 21 rotates counterclockwise, the handle 51 to which the pinion 21 is attached also rotates counterclockwise.
　ハンドル５１が反時計回りに回転すると、リンク５９の下脚部５９０が、上脚部５９１とハンドル軸６５とを結ぶ線分よりも前側へ移動し、リンク５９は下側に引き下げられる。このとき、リンク５９の上脚部５９１が下側へ移動することで可動バー５３のストッパ片５３１に対する押圧がなくなり、可動バー５３は、加圧ばねのばね力により軸６３の周りで反時計回りに急速に回転し、可動接点５３０が固定接点５２０に勢いよく当接する。 When the handle 51 rotates counterclockwise, the lower leg portion 590 of the link 59 moves to the front side from the line segment connecting the upper leg portion 591 and the handle shaft 65, and the link 59 is pulled down. At this time, the upper leg portion 591 of the link 59 moves downward so that the movable bar 53 is not pressed against the stopper piece 531, and the movable bar 53 rotates counterclockwise around the shaft 63 by the spring force of the pressure spring. The movable contact 530 comes into contact with the fixed contact 520 vigorously.
　これにより、可動接点５３０が固定接点５２０に短時間で接触することになり、アークの発生を抑制することができる。また、ラッチ部材５７は、ラッチばね６０のばね力によって反時計回りに回転する。 Thereby, the movable contact 530 comes into contact with the fixed contact 520 in a short time, and the generation of the arc can be suppressed. The latch member 57 rotates counterclockwise by the spring force of the latch spring 60.
　次に、電動車両２の蓄電池３３の充電又は放電が完了すると、電動車両２から出力される完了信号によってソレノイド装置２４が起動し、ピン２４１が後方に引っ込められる。これにより、解除釦２３の押操作が可能になる。そして、コイルばね２５の弾性力に抗して解除釦２３が押操作されると、解除釦２３に取り付けられた解除部材２６が下方へ移動し、ロック部材１５の引掛部１５２と解除部材２６の段部２６１の係合状態が解除される。 Next, when charging or discharging of the storage battery 33 of the electric vehicle 2 is completed, the solenoid device 24 is activated by a completion signal output from the electric vehicle 2, and the pin 241 is retracted backward. As a result, the release button 23 can be pressed. When the release button 23 is pushed against the elastic force of the coil spring 25, the release member 26 attached to the release button 23 moves downward, and the hooking portion 152 of the lock member 15 and the release member 26 The engaged state of the stepped portion 261 is released.
　このとき、解除部材２６の引掛部２６２も下方へ移動するため、この引掛部２６２によりてこ２７の後側の腕部２７２が下向きに押圧され、てこ２７が時計回りに回転する。そして、てこ２７の前側の腕部２７１によってロック部材１５の引掛部１５２が上向きに押圧され、ロック部材１５が反時計回りに回転して引掛部１５１と段部４１１ａの係合状態が解除される。 At this time, since the hooking portion 262 of the release member 26 also moves downward, the arm portion 272 on the rear side of the lever 27 is pressed downward by the hooking portion 262, and the lever 27 rotates clockwise. Then, the hook portion 152 of the lock member 15 is pressed upward by the arm portion 271 on the front side of the lever 27, and the lock member 15 rotates counterclockwise to release the engagement state between the hook portion 151 and the step portion 411a. .
　またこのとき、解除部材２６が下方へ移動することで連動部材３０も下方へ移動し、連動部材３０によってラッチ部材５７の押圧片５７３が下向きに押圧され、これによりラッチ部材５７が軸６４の周りで時計回りに回転する。ラッチ部材５７が時計回りに回転すると、ラッチ部材５７からの押圧力によって軸６３が後方へ移動し、それに伴って可動バー５３も後方へ移動する。その結果、可動接点５３０が固定接点５２０から開離し、接点部３１が開成する。 At this time, when the release member 26 moves downward, the interlocking member 30 also moves downward, and the pressing member 573 of the latch member 57 is pressed downward by the interlocking member 30, whereby the latch member 57 is rotated around the shaft 64. To rotate clockwise. When the latch member 57 rotates clockwise, the shaft 63 moves rearward by the pressing force from the latch member 57, and the movable bar 53 moves rearward accordingly. As a result, the movable contact 530 is separated from the fixed contact 520, and the contact portion 31 is opened.
　引掛部１５１と段部４１１ａの係合状態が解除された後、解除釦２３を押したままケース１０を後方へ移動させると、給電ソケット４３の接圧によってコンタクト１３はインレット４側に保持されるため、ケース１０のみが後方へ移動する。 After the engagement state between the hooking portion 151 and the stepped portion 411a is released, when the case 10 is moved backward while the release button 23 is pressed, the contact 13 is held on the inlet 4 side by the contact pressure of the power supply socket 43. Therefore, only the case 10 moves backward.
　このとき、コンタクト１３に連結されたリンク１４が反時計回りに回転し、リンク１４に取り付けられた軸１６も前側へ移動し、それに伴ってロック部材１５も前側へ移動する。ロック部材１５が前側へ移動すると、ロック部材１５の引掛部１５２がケース１０の突起１１５と係合し、先端の引掛部１５１がケース１０内に引っ込んだ状態になる（図１に示す状態）。 At this time, the link 14 connected to the contact 13 rotates counterclockwise, the shaft 16 attached to the link 14 also moves to the front side, and accordingly, the lock member 15 also moves to the front side. When the locking member 15 moves forward, the hooking portion 152 of the locking member 15 engages with the protrusion 115 of the case 10, and the hooking portion 151 at the tip is retracted into the case 10 (the state shown in FIG. 1).
　さらにこのとき、コンタクト１３に取り付けられたラック１９も前側へ移動し、ラック１９と噛み合うピニオン２０は反時計回りに回転する。また、ピニオン２０と噛み合うピニオン２１は時計回りに回転し、ピニオン２１が取り付けられたハンドル５１も時計回りに回転する。 Further, at this time, the rack 19 attached to the contact 13 also moves to the front side, and the pinion 20 that meshes with the rack 19 rotates counterclockwise. The pinion 21 that meshes with the pinion 20 rotates clockwise, and the handle 51 to which the pinion 21 is attached also rotates clockwise.
　ハンドル５１が時計回りに回転すると、リンク５８の上脚部５８１が下側に引き下げられる。これにより、リンク５８が支持アーム５６を押圧する力がなくなる。そして、可動バー５３は、加圧ばねのばね力によって軸６３の周りで反時計回りに回転し、支持アーム５６は、加圧ばねのばね力によって軸６４の周りで時計回りに回転する。 When the handle 51 rotates clockwise, the upper leg portion 581 of the link 58 is pulled down. Thereby, the force by which the link 58 presses the support arm 56 is lost. The movable bar 53 rotates counterclockwise around the shaft 63 by the spring force of the pressurizing spring, and the support arm 56 rotates clockwise around the shaft 64 by the spring force of the pressurizing spring.
　支持アーム５６は、軸６３がガイドリブ（図示せず）の後端位置（図１中の右端位置）まで移動した位置で停止し、可動バー５３は、ストッパ片５３１が支持アーム５６の係合片５６３に当接した位置で停止する。 The support arm 56 stops at a position where the shaft 63 has moved to the rear end position (right end position in FIG. 1) of the guide rib (not shown), and the movable bar 53 has the stopper piece 531 engaging with the support arm 56. It stops at the position where it abuts on 563.
　図６は本実施形態の別の電気接続用コネクタ１を示す側面図である。上述の図１及び図２に示した電気接続用コネクタ１では、解除部材２６とラッチ部材５７の間に連動部材３０を配置したが、図６に示すように、ロック部材１５とラッチ部材５７の間に連動部材３０を配置してもよい。 FIG. 6 is a side view showing another electrical connection connector 1 of the present embodiment. In the electrical connection connector 1 shown in FIGS. 1 and 2 described above, the interlocking member 30 is disposed between the release member 26 and the latch member 57. However, as shown in FIG. The interlocking member 30 may be disposed between them.
　この場合、解除釦２３を押した後、てこ２７を介してロック部材１５が反時計回りに回転するタイミングで接点部３１が開成する。なお、それ以外の構成については図１及び図２に示した電気接続用コネクタ１と同様であり、ここでは詳細な説明を省略する。 In this case, after pressing the release button 23, the contact portion 31 is opened at the timing when the lock member 15 rotates counterclockwise via the lever 27. The other configuration is the same as that of the electrical connection connector 1 shown in FIGS. 1 and 2, and detailed description thereof is omitted here.
　図７は本実施形態のさらに別の電気接続用コネクタ１の要部を説明する説明図である。上述の実施例では、連動部材３０によってラッチ部材５７を押圧し、ラッチ部材５７に連結された可動バー５３を開成方向へ直接移動させたが、図７に示すように、マイクロスイッチ３４（スイッチ）を介して電気的に接点部３１を開成するようにしてもよい。一例としては、リモコンブレーカーやリモコンリレーなどが挙げられる。 FIG. 7 is an explanatory diagram for explaining a main part of still another electrical connection connector 1 of the present embodiment. In the above-described embodiment, the latch member 57 is pressed by the interlocking member 30 and the movable bar 53 connected to the latch member 57 is directly moved in the opening direction. However, as shown in FIG. You may make it open the contact part 31 electrically via. An example is a remote control breaker or a remote control relay.
　この場合、解除部材２６又はロック部材１５によって押圧された連動部材３０によりマイクロスイッチ３４のスイッチレバー３４１が押圧され、マイクロスイッチ３４から出力される電気信号により接点部３１を開成させる。本構成によれば、連動部材３０によりラッチ部材５７を直接押圧する場合に比べて、耐用回数を向上させることができる。 In this case, the switch lever 341 of the micro switch 34 is pressed by the interlocking member 30 pressed by the release member 26 or the lock member 15, and the contact portion 31 is opened by the electrical signal output from the micro switch 34. According to this structure, compared with the case where the latch member 57 is directly pressed by the interlocking member 30, the number of service life can be improved.
　また本例において、電気接続用コネクタ１をインレット４に接続する際には、上述のラック１９及びピニオン２０，２１によってハンドル５１を回転させ、上述の動作を経て接点部３１を閉成させる。ここに本例では、ハンドル５１により開閉部材が構成され、ラック１９及びピニオン２０，２１により移動機構が構成されている。 Further, in this example, when the electrical connection connector 1 is connected to the inlet 4, the handle 51 is rotated by the rack 19 and the pinions 20 and 21, and the contact portion 31 is closed through the above-described operation. In this example, the handle 51 constitutes an opening / closing member, and the rack 19 and the pinions 20 and 21 constitute a moving mechanism.
　このように、本実施形態の電気接続用コネクタ１によれば、第１接触部４４と第２接触部４３０（給電ソケット４３の内側面）の接触状態が解除される前に接点部３１を開成することができる。その結果、電気接続用コネクタ１をインレット４から取り外す際に、第１接触部４４と第２接触部４３０の間にアークが発生するのを抑えることができる。 Thus, according to the electrical connection connector 1 of the present embodiment, the contact portion 31 is opened before the contact state between the first contact portion 44 and the second contact portion 430 (the inner surface of the power supply socket 43) is released. can do. As a result, when the electrical connection connector 1 is removed from the inlet 4, it is possible to suppress the generation of an arc between the first contact portion 44 and the second contact portion 430.
　また、ロック部材１５や解除部材２６に作用する力をラッチ部材５７やマイクロスイッチ３４に伝達する連動部材３０を設けるだけで接点部３１を開成することができ、コストアップを抑えつつアークの発生を抑えた電気接続用コネクタ１を提供することができる。さらに、上述のハウジング５０を密閉容器とした場合には、接点部３１に発生するアークが外に出ることなく、安全性及び耐環境性を高めることもできる。 Further, the contact portion 31 can be opened only by providing the interlocking member 30 that transmits the force acting on the lock member 15 and the release member 26 to the latch member 57 and the micro switch 34, and the generation of an arc is suppressed while suppressing an increase in cost. The suppressed connector 1 for electrical connection can be provided. Furthermore, when the above-described housing 50 is a sealed container, the arc generated at the contact portion 31 does not go out, and safety and environmental resistance can be improved.
　ところで、インレット４に接続された電気接続用コネクタ１を無理矢理引き抜いたり、電気接続用コネクタ１に対して衝撃が加えられると、ロック部材１５の引掛部１５１とインレット４の段部４１１ａの係合箇所に負荷が加わる。そのため、この負荷によってロック部材１５に下向きの力が加えられ、ロック部材１５が変形する。 By the way, when the electrical connection connector 1 connected to the inlet 4 is forcibly pulled out or an impact is applied to the electrical connection connector 1, the engagement portion 151 of the locking member 15 and the step portion 411 a of the inlet 4 are engaged. Load. Therefore, a downward force is applied to the lock member 15 by this load, and the lock member 15 is deformed.
　そして、ロック部材１５とラッチ部材５７の間に連動部材３０が配置されている場合には、ロック部材１５に与えられる力によって連動部材３０が下方に押圧され、その結果、接点部３１を開成することができる。つまりこの場合も、上述の実施例と同様に、第１接触部４４と第２接触部４３０の間にアークが発生するのを抑えることができる。 When the interlocking member 30 is disposed between the lock member 15 and the latch member 57, the interlocking member 30 is pressed downward by the force applied to the lock member 15, and as a result, the contact portion 31 is opened. be able to. That is, in this case as well, it is possible to suppress the generation of an arc between the first contact portion 44 and the second contact portion 430 as in the above-described embodiment.
　また、解除部材２６とラッチ部材５７の間に連動部材３０を配置した電気接続用コネクタ１において、解除部材２６が変形することで接点部３１を開成できるようにしてもよい。 Further, in the electrical connection connector 1 in which the interlocking member 30 is disposed between the release member 26 and the latch member 57, the contact portion 31 may be opened when the release member 26 is deformed.
　なお、マイクロスイッチ３４の接点構成は、本実施形態のようにａ接点のものに限定されるものではなく、ｂ接点でもよい。この場合、マイクロスイッチ３４より電気信号が常時出力され、連動部材３０によってスイッチレバー３４１が押されると上記電気信号が出力されなくなる。そして、上記電気信号が出力されなくなったことを受けて、ソレノイド装置２４が起動し、ピン２４１を前方に伸ばすことになる。 Note that the contact configuration of the micro switch 34 is not limited to that of the a contact as in the present embodiment, and may be a b contact. In this case, an electrical signal is always output from the microswitch 34, and when the switch lever 341 is pushed by the interlocking member 30, the electrical signal is not output. Then, when the electrical signal is no longer output, the solenoid device 24 is activated and the pin 241 is extended forward.
　また、本実施形態では、マイクロスイッチ３４を用いているが、連動部材３０により接点がオン／オフされるものであれば他のスイッチであってもよく、マイクロスイッチ３４に限定されるものではない。さらに、本実施形態では、電動車両２の蓄電池３３の充電と放電の両方を行なう構成としたが、蓄電池３３の充電と放電の何れか一方のみを行なう構成であってもよく、本実施形態に限定されない。 In the present embodiment, the micro switch 34 is used. However, other switches may be used as long as the contact point is turned on / off by the interlocking member 30, and the switch is not limited to the micro switch 34. . Furthermore, in this embodiment, although it was set as the structure which performs both charge and discharge of the storage battery 33 of the electric vehicle 2, the structure which performs only one of charge and discharge of the storage battery 33 may be sufficient, and this embodiment is included in this embodiment. It is not limited.
　また、本実施形態では、蓄電池３３の充電方式としてＣＨＡｄｅＭＯ（登録商標）方式を採用したが、他の充電方式（例えばコンボ方式）であってもよく、本実施形態に限定されない。 In this embodiment, the CHAdeMO (registered trademark) system is adopted as the charging system of the storage battery 33, but other charging systems (for example, a combo system) may be used, and the present invention is not limited to this embodiment.
