Then, between the contact plate portions 25 of the female terminals 24, the terminal plate portions 14 of the pair of terminals 13 arranged so as to sandwich the insulating plate portion 17 constituting the male terminal 50 of the first connector housing 10 are inserted. Get caught. When the terminal plate portion 14 of the pair of terminals 13 is inserted between the contact plate portions 25 of the female terminal 24, the power lines 2 connected to the pair of terminals 13 are electrically connected to each other via the female terminal 24. Will be done.

第２コネクタハウジング２０の内周筒部２２の内部には、導電性金属材料から形成されたショート端子２６が設けられている。このショート端子２６は、一対の雄端子部２７を有している。このショート端子２６の雄端子部２７は、第１コネクタハウジング１０の一対のサブ端子４に接続可能とされている。このショート端子２６の雄端子部２７がサブ端子４にそれぞれ接続されると、サブ端子４に接続された信号線３同士がショート端子２６を介して電気的に接続される。 A short terminal 26 formed of a conductive metal material is provided inside the inner peripheral cylinder portion 22 of the second connector housing 20. The short terminal 26 has a pair of male terminal portions 27. The male terminal portion 27 of the short terminal 26 can be connected to a pair of sub-terminals 4 of the first connector housing 10. When the male terminal portion 27 of the short terminal 26 is connected to the sub terminal 4, the signal lines 3 connected to the sub terminal 4 are electrically connected to each other via the short terminal 26.

レバー４０は、合成樹脂から成形されたもので、一対のアーム部４１と、連結部４２とを有している。アーム部４１は、一端側が連結部４２によって連結されており、他端近傍に軸受孔４４を有している。アーム部４１の軸受孔４４には、第２コネクタハウジング２０の支持軸２３が挿入されており、これにより、レバー４０は、第２コネクタハウジング２０に対して回動可能に支持されている。レバー４０は、アーム部４１の他端が湾曲面４５を有する押圧部４６とされている。 The lever 40 is molded from a synthetic resin and has a pair of arm portions 41 and a connecting portion 42. One end of the arm portion 41 is connected by a connecting portion 42, and the arm portion 41 has a bearing hole 44 in the vicinity of the other end. A support shaft 23 of the second connector housing 20 is inserted into the bearing hole 44 of the arm portion 41, whereby the lever 40 is rotatably supported with respect to the second connector housing 20. The lever 40 is a pressing portion 46 having a curved surface 45 at the other end of the arm portion 41.

第２コネクタハウジング２０に回動可能に支持されたレバー４０は、挿抜方向Ａに沿う離脱操作位置（図２参照）と、挿抜方向Ａに直交する方向に沿う本嵌合操作位置（図１参照）との間で回動する。 The lever 40 rotatably supported by the second connector housing 20 has a detachment operation position along the insertion / removal direction A (see FIG. 2) and a main fitting operation position along the direction orthogonal to the insertion / removal direction A (see FIG. 1). ) And.

上記構成のコネクタ１は、雄端子５０と雌端子２４とからメインスイッチ部（スイッチ部）ＭＳｗが構成され、サブ端子４とショート端子２６とからサブスイッチ部ＳＳｗが構成されている（図２参照）。このコネクタ１を電源回路遮断装置として備えた電源装置等では、メインスイッチ部ＭＳｗがオン状態とされて電源線２同士が電気的に接続されることで電源回路が形成され、サブスイッチ部ＳＳｗがオン状態とされて信号線３同士が電気的に接続されることで信号回路が形成される。そして、電源回路遮断装置を備えた電源装置等では、メインスイッチ部ＭＳｗがオン状態となって電源回路が形成されたとしても、サブスイッチ部ＳＳｗがオン状態となって信号回路が形成されない限り電源回路を導通状態としないように構成されている。即ち、メインスイッチ部ＭＳｗとサブスイッチ部ＳＳｗが共にオン状態となって初めて電源回路を導通状態とすることができる。 In the connector 1 having the above configuration, the main switch section (switch section) MSw is configured from the male terminal 50 and the female terminal 24, and the sub switch section SSw is configured from the sub terminal 4 and the short terminal 26 (see FIG. 2). ). In a power supply device or the like provided with this connector 1 as a power supply circuit cutoff device, the main switch unit MSw is turned on and the power supply lines 2 are electrically connected to each other to form a power supply circuit, and the sub switch unit SSw is formed. A signal circuit is formed by being turned on and the signal lines 3 being electrically connected to each other. In a power supply device or the like provided with a power supply circuit cutoff device, even if the main switch unit MSw is turned on and the power supply circuit is formed, the power supply is not formed unless the sub switch unit SSw is turned on and the signal circuit is formed. It is configured so that the circuit is not in a conductive state. That is, the power supply circuit can be brought into a conductive state only when both the main switch section MSw and the sub switch section SSw are turned on.

次に、メインスイッチ部ＭＳｗの具体的な構造について説明する。
図５は、メインスイッチ部ＭＳｗを説明するコネクタ１の幅方向に沿う断面図である。 Next, the specific structure of the main switch unit MSw will be described.
FIG. 5 is a cross-sectional view taken along the width direction of the connector 1 for explaining the main switch portion MSw.

図５に示すように、第１コネクタハウジング１０の収容筒部１２は、その底部１２ａから絶縁板部１７に沿って延びるランス（可撓係止片）５１を有している。このランス５１は、その先端部に、絶縁板部１７側へ向かって突出する係止爪５２が形成されている。収容筒部１２には、絶縁板部１７と各ランス５１との間に、挿通口５３が形成されており、この挿通口５３から端子１３の端子板部１４が挿し込まれる。また、絶縁板部１７には、その上端部に、位置決め部５４が形成されている。この位置決め部５４は、その断面形状が、第２コネクタハウジング２０へ向かって窄まる先細り形状とされている。端子１３は、収容筒部１２の挿通口５３から端子板部１４を挿し込むことで第１コネクタハウジング１０に組付けられる。挿通口５３に挿し込まれる端子板部１４は、その上端が位置決め部５４に当接されて位置決めされ、絶縁板部１７に沿って配置される。この状態で、端子板部１４の係止孔１４ｂにランス５１の係止爪５２が入り込み、これにより、端子板部１４が第１コネクタハウジング１０に係止される。そして、この第１コネクタハウジング１０では、電気絶縁性を有する絶縁板部１７と、この絶縁板部１７を介してそれぞれの端子板部１４が電気的に絶縁状態に重ね合わされた一対の端子１３とから、雄端子５０が構成されている。 As shown in FIG. 5, the housing cylinder portion 12 of the first connector housing 10 has a lance (flexible locking piece) 51 extending from the bottom portion 12a along the insulating plate portion 17. The lance 51 has a locking claw 52 formed at the tip thereof so as to project toward the insulating plate portion 17. An insertion port 53 is formed between the insulating plate portion 17 and each lance 51 in the accommodating cylinder portion 12, and the terminal plate portion 14 of the terminal 13 is inserted from the insertion port 53. Further, the insulating plate portion 17 is formed with a positioning portion 54 at the upper end portion thereof. The cross-sectional shape of the positioning portion 54 has a tapered shape that narrows toward the second connector housing 20. The terminal 13 is assembled to the first connector housing 10 by inserting the terminal plate portion 14 from the insertion port 53 of the accommodating cylinder portion 12. The upper end of the terminal plate portion 14 to be inserted into the insertion port 53 is abutted against the positioning portion 54 and is positioned, and is arranged along the insulating plate portion 17. In this state, the locking claw 52 of the lance 51 enters the locking hole 14b of the terminal plate portion 14, whereby the terminal plate portion 14 is locked to the first connector housing 10. Then, in the first connector housing 10, an insulating plate portion 17 having an electrical insulating property and a pair of terminals 13 in which the respective terminal plate portions 14 are electrically superposed in an insulated state via the insulating plate portion 17 are provided. Therefore, the male terminal 50 is configured.

また、収容筒部１２には、二対の触指防止壁６１が形成されている。これらの触指防止壁６１は、収容筒部１２の底部１２ａから立設されており、それぞれ絶縁板部１７に対して隙間をあけて配置されている。これらの触指防止壁６１は、端子１３の端子板部１４よりも上方の第２コネクタハウジング２０側へ延在されている。これにより、触指防止壁６１の上端位置は、端子１３の端子板部１４の上端よりも上方である第２コネクタハウジング２０側とされている。これにより、第１コネクタハウジング１０では、端子１３の端子板部１４の表面側が平面視において触指防止壁６１によって覆われ、第２コネクタハウジング２０の装着側から端子板部１４へのユーザによる接触が抑制されている。つまり、この触指防止壁６１は、電源のメインスイッチ部ＭＳｗを構成する端子１３の端子板部１４に対する触指を防止する機能を有している。 Further, two pairs of tactile prevention walls 61 are formed on the accommodating cylinder portion 12. These tactile prevention walls 61 are erected from the bottom portion 12a of the accommodating cylinder portion 12, and are arranged with a gap from each of the insulating plate portions 17. These tactile prevention walls 61 extend toward the second connector housing 20 above the terminal plate portion 14 of the terminal 13. As a result, the upper end position of the finger touch prevention wall 61 is set to the side of the second connector housing 20 which is above the upper end of the terminal plate portion 14 of the terminal 13. As a result, in the first connector housing 10, the surface side of the terminal plate portion 14 of the terminal 13 is covered with the tactile prevention wall 61 in a plan view, and the user contacts the terminal plate portion 14 from the mounting side of the second connector housing 20. Is suppressed. That is, the tactile prevention wall 61 has a function of preventing tactile fingers from the terminal plate portion 14 of the terminal 13 constituting the main switch portion MSw of the power supply.

触指防止壁６１の内面には、端子板部１４との対向側における下方側に、変位抑制部６２が突設されている。変位抑制部６２は、触指防止壁６１の肉厚を端子板部１４との対向側に厚くした部分からなるもので、端子板部１４側へ突出されている。なお、この変位抑制部６２は、第１コネクタハウジング１０と第２コネクタハウジング２０との挿抜方向Ａに沿って突設された複数の突条リブであってもよい。 On the inner surface of the tactile prevention wall 61, a displacement suppressing portion 62 is projected on the lower side on the side facing the terminal plate portion 14. The displacement suppressing portion 62 is formed of a portion in which the wall thickness of the tactile prevention wall 61 is increased on the side facing the terminal plate portion 14, and is projected toward the terminal plate portion 14. The displacement suppressing portion 62 may be a plurality of ridge ribs projecting along the insertion / removal direction A of the first connector housing 10 and the second connector housing 20.

第２コネクタハウジング２０に組付けられた雌端子２４は、図４に示すように、それぞれの接点板部２５が、挿抜方向Ａに沿って延在する複数の接触片７１を有している。これらの接触片７１を有する接点板部２５は、延在方向へ向かって互いに近接する方向へ傾斜されている。これにより、雌端子２４は、接点板部２５が先窄み形状とされている。それぞれの接点板部２５の接触片７１は、その先端が端子板部１４に徐々に近づく方向から離間する方向へ屈曲部７２で屈曲されている。そして、それぞれの接触片７１の先端部分における屈曲部７２は、互いに近接する方向へ突出する接点を構成している。 As shown in FIG. 4, each of the contact plate portions 25 of the female terminal 24 assembled to the second connector housing 20 has a plurality of contact pieces 71 extending along the insertion / removal direction A. The contact plate portion 25 having these contact pieces 71 is inclined in a direction close to each other in the extending direction. As a result, the female terminal 24 has a contact plate portion 25 having a narrowed tip. The contact piece 71 of each contact plate portion 25 is bent at the bending portion 72 in a direction in which the tip thereof gradually approaches the terminal plate portion 14 and separates from the contact piece 71. The bent portion 72 at the tip of each contact piece 71 constitutes a contact point that projects in a direction close to each other.

図６は、第１コネクタハウジング１０と第２コネクタハウジング２０とを嵌合させたコネクタ１の幅方向に沿う断面図である。
図６に示すように、メインスイッチ部ＭＳｗでは、第１コネクタハウジング１０に対して第２コネクタハウジング２０が嵌合されると、雌端子２４の接点板部２５の間に、雄端子５０が挿し込まれて互いに接続される。すると、雌端子２４の各接点板部２５の接触片７１の接点である屈曲部７２が雄端子５０を構成する端子板部１４の突条部１４ａにそれぞれ接触する。これにより、雌端子２４を介して一対の端子１３同士が導通されてメインスイッチ部ＭＳｗがオン状態となり、電源線２同士が電気的に接続されて電源回路が形成される。また、雄端子５０に雌端子２４が接続されると、雌端子２４の接点板部２５の各接触片７１の先端部分における端子板部１４に接触する内側部分と反対側の外側部分が触指防止壁６１の内面に突設された変位抑制部６２に当接する。 FIG. 6 is a cross-sectional view taken along the width direction of the connector 1 in which the first connector housing 10 and the second connector housing 20 are fitted.
As shown in FIG. 6, in the main switch portion MSw, when the second connector housing 20 is fitted to the first connector housing 10, the male terminal 50 is inserted between the contact plate portions 25 of the female terminal 24. Being embedded and connected to each other. Then, the bent portion 72, which is the contact point of the contact piece 71 of each contact plate portion 25 of the female terminal 24, comes into contact with the ridge portion 14a of the terminal plate portion 14 constituting the male terminal 50, respectively. As a result, the pair of terminals 13 are electrically connected to each other via the female terminals 24, the main switch portion MSw is turned on, and the power supply lines 2 are electrically connected to each other to form a power supply circuit. Further, when the female terminal 24 is connected to the male terminal 50, the outer portion on the opposite side to the inner portion in contact with the terminal plate portion 14 at the tip portion of each contact piece 71 of the contact plate portion 25 of the female terminal 24 is touched. It abuts on the displacement suppressing portion 62 projecting from the inner surface of the prevention wall 61.

次に、コネクタ１において、第１コネクタハウジング１０に対して第２コネクタハウジング２０を嵌合及び離脱させる場合について説明する。 Next, in the connector 1, a case where the second connector housing 20 is fitted and detached from the first connector housing 10 will be described.

（嵌合させる場合）
第１コネクタハウジング１０に第２コネクタハウジング２０を嵌合させるには、第１コネクタハウジング１０に対して、レバー４０を離脱操作位置に配置させた第２コネクタハウジング２０を近接させる。そして、第１コネクタハウジング１０の収容筒部１２に、第２コネクタハウジング２０の内周筒部２２を嵌め込む。 (When mating)
In order to fit the second connector housing 20 into the first connector housing 10, the second connector housing 20 in which the lever 40 is arranged at the detachment operation position is brought close to the first connector housing 10. Then, the inner peripheral cylinder portion 22 of the second connector housing 20 is fitted into the accommodating cylinder portion 12 of the first connector housing 10.

この状態では、雌端子２４の接触片７１は、雄端子５０の端子板部１４から離間されている。つまり、メインスイッチ部ＭＳｗはオフ状態であり、電源線２同士が非接続状態とされている。また、ショート端子２６の雄端子部２７もサブ端子４から離間されている。つまり、サブスイッチ部ＳＳｗはオフ状態であり、サブ端子４に接続された信号線３同士が非接続状態とされている。 In this state, the contact piece 71 of the female terminal 24 is separated from the terminal plate portion 14 of the male terminal 50. That is, the main switch unit MSw is in the off state, and the power supply lines 2 are not connected to each other. Further, the male terminal portion 27 of the short terminal 26 is also separated from the sub terminal 4. That is, the sub switch unit SSw is in the off state, and the signal lines 3 connected to the sub terminal 4 are not connected to each other.

この状態において、離脱操作位置のレバー４０を本嵌合操作位置へ向かって回動させる。すると、レバー４０の押圧部４６の湾曲面４５が第１コネクタハウジング１０の側壁部１１に形成された支点突起１１ａに当接して摺動する。これにより、第１コネクタハウジング１０と第２コネクタハウジング２０との間に嵌合力が付与され、第２コネクタハウジング２０が第１コネクタハウジング１０に引き込まれる。 In this state, the lever 40 at the detachment operation position is rotated toward the main fitting operation position. Then, the curved surface 45 of the pressing portion 46 of the lever 40 abuts on the fulcrum protrusion 11a formed on the side wall portion 11 of the first connector housing 10 and slides. As a result, a fitting force is applied between the first connector housing 10 and the second connector housing 20, and the second connector housing 20 is pulled into the first connector housing 10.

レバー４０が本嵌合操作位置に達すると、第１コネクタハウジング１０と第２コネクタハウジング２０とが互いに完全嵌合した本嵌合状態とされる。この本嵌合状態では、雌端子２４の接点板部２５の間に雄端子５０が挿入されて一対の端子１３の端子板部１４に接触される。つまり、メインスイッチ部ＭＳｗがオン状態となり、一対の端子１３に接続された電源線２同士が雌端子２４を介して電気的に接続される。また、ショート端子２６の雄端子部２７がサブ端子４に接続される。つまり、サブスイッチ部ＳＳｗがオン状態となり、サブ端子４に接続された信号線３同士がショート端子２６を介して電気的に接続される。 When the lever 40 reaches the main fitting operation position, the first connector housing 10 and the second connector housing 20 are in the main fitting state in which they are completely fitted to each other. In this mated state, the male terminal 50 is inserted between the contact plate portions 25 of the female terminals 24 and comes into contact with the terminal plate portions 14 of the pair of terminals 13. That is, the main switch portion MSw is turned on, and the power supply lines 2 connected to the pair of terminals 13 are electrically connected to each other via the female terminals 24. Further, the male terminal portion 27 of the short terminal 26 is connected to the sub terminal 4. That is, the sub switch unit SSw is turned on, and the signal lines 3 connected to the sub terminal 4 are electrically connected to each other via the short terminal 26.

（離脱させる場合）
第１コネクタハウジング１０から第２コネクタハウジング２０を離脱させるには、本嵌合操作位置に配置されたレバー４０の連結部４２を把持して引き上げ、離脱操作位置へ向かって回動させる。 (When leaving)
In order to disengage the second connector housing 20 from the first connector housing 10, the connecting portion 42 of the lever 40 arranged at the main fitting operation position is grasped and pulled up, and the second connector housing 20 is rotated toward the disengagement operation position.

レバー４０を離脱操作位置へ向かって回動させると、レバー４０の回動に伴って、レバー４０の押圧部４６が第１コネクタハウジング１０のフランジ部１０ａの表面に当接して摺動する。これにより、第１コネクタハウジング１０と第２コネクタハウジング２０との間に離脱力が付与される。したがって、第１コネクタハウジング１０に対して本嵌合状態とされていた第２コネクタハウジング２０が第１コネクタハウジング１０から引き離されて離脱する方向へ変位する。 When the lever 40 is rotated toward the detachment operation position, the pressing portion 46 of the lever 40 abuts on the surface of the flange portion 10a of the first connector housing 10 and slides as the lever 40 rotates. As a result, a detaching force is applied between the first connector housing 10 and the second connector housing 20. Therefore, the second connector housing 20 that has been in the main fitted state with respect to the first connector housing 10 is separated from the first connector housing 10 and displaced in the direction of detachment.

第２コネクタハウジング２０が第１コネクタハウジング１０から離脱する方向へ変位すると、まず、サブ端子４からショート端子２６の雄端子部２７が引き抜かれる。つまり、サブスイッチ部ＳＳｗがオフ状態とされ、信号線３同士の電気的接続が解除される。 When the second connector housing 20 is displaced in the direction of detaching from the first connector housing 10, the male terminal portion 27 of the short terminal 26 is first pulled out from the sub terminal 4. That is, the sub switch unit SSw is turned off, and the electrical connection between the signal lines 3 is released.

そして、レバー４０が離脱操作位置に達し、第２コネクタハウジング２０が第１コネクタハウジング１０からさらに離脱する方向へ変位すると、一対の端子１３の端子板部１４に接触していた雌端子２４の接点板部２５が外れる。これにより、メインスイッチ部ＭＳｗがオフ状態とされ、電源線２同士の電気的接続状態が解除される。 Then, when the lever 40 reaches the disconnection operation position and the second connector housing 20 is displaced in the direction of further detachment from the first connector housing 10, the contact point of the female terminal 24 that has been in contact with the terminal plate portion 14 of the pair of terminals 13. The plate portion 25 comes off. As a result, the main switch portion MSw is turned off, and the electrical connection state between the power supply lines 2 is released.

その後、第１コネクタハウジング１０から第２コネクタハウジング２０を引き離すと、第２コネクタハウジング２０の内周筒部２２が第１コネクタハウジング１０の収容筒部１２から引き抜かれ、第１コネクタハウジング１０から第２コネクタハウジング２０が離脱される。 After that, when the second connector housing 20 is pulled away from the first connector housing 10, the inner peripheral cylinder portion 22 of the second connector housing 20 is pulled out from the accommodating cylinder portion 12 of the first connector housing 10, and the first connector housing 10 is pulled out from the first connector housing 10. 2 The connector housing 20 is detached.

このように、上記の電源回路遮断装置として用いられるコネクタ１では、メインスイッチ部ＭＳｗは、サブスイッチ部ＳＳｗがオフ状態とされて信号線３同士の電気的接続状態が解除されて電源回路への通電がオフされた後にメインスイッチ部ＭＳｗがオフ状態とされて電源線２同士の電気的接続状態が解除される。これにより、電源線２同士の接続が解除されることで生じるアークやスパーク等の発生を抑制することができる。 As described above, in the connector 1 used as the power supply circuit cutoff device, the main switch unit MSw has the sub switch unit SSw turned off and the electrical connection state between the signal lines 3 is released to the power supply circuit. After the energization is turned off, the main switch portion MSw is turned off and the electric connection state between the power supply lines 2 is released. As a result, it is possible to suppress the generation of arcs, sparks, and the like that occur when the power lines 2 are disconnected from each other.

ここで、参考例に係るコネクタについて説明する。
図７は、参考例に係るコネクタ１００の幅方向に沿う断面図である。 Here, the connector according to the reference example will be described.
FIG. 7 is a cross-sectional view taken along the width direction of the connector 100 according to the reference example.

図７に示すように、参考例に係るコネクタ１００では、変位抑制部６２が設けられていない。つまり、このコネクタ１００では、第１コネクタハウジング１０と第２コネクタハウジング２０とが嵌合した状態で、雌端子２４の接触片７１は、雄端子５０の端子板部１４と接触する内側部分と反対側の外側部分が触指防止壁６１などの構造物のいずれにも接触しない。 As shown in FIG. 7, the connector 100 according to the reference example is not provided with the displacement suppressing portion 62. That is, in this connector 100, the contact piece 71 of the female terminal 24 is opposite to the inner portion in contact with the terminal plate portion 14 of the male terminal 50 in a state where the first connector housing 10 and the second connector housing 20 are fitted. The outer portion on the side does not come into contact with any of the structures such as the tactile prevention wall 61.

このコネクタ１００において、第１コネクタハウジング１０と第２コネクタハウジング２０とが繰り返し嵌合及び離脱され、雌端子２４と雄端子５０との挿抜が繰り返されたり、意図せずに過剰に変位されたり、通電等によって熱が付与されると、弾性力によって雄端子５０の端子板部１４に押圧させて接触させる雌端子２４の接触片７１にへたりが生じるおそれがある。すると、雌端子２４の接点板部２５の接触片７１同士の間に雄端子５０が挿し込まれても、端子板部１４と接触片７１との間に隙間Ｇが生じ、接続信頼性が低下するおそれがある。 In this connector 100, the first connector housing 10 and the second connector housing 20 are repeatedly fitted and detached, and the female terminal 24 and the male terminal 50 are repeatedly inserted and removed, or are unintentionally excessively displaced. When heat is applied by energization or the like, the contact piece 71 of the female terminal 24 which is pressed against the terminal plate portion 14 of the male terminal 50 to be brought into contact with the male terminal 50 may be settled. Then, even if the male terminal 50 is inserted between the contact pieces 71 of the contact plate portion 25 of the female terminal 24, a gap G is generated between the terminal plate portion 14 and the contact piece 71, and the connection reliability is lowered. There is a risk of doing so.

これに対して、本第１実施形態に係るコネクタ１によれば、雄端子５０に雌端子２４が接続されると、雌端子２４の接点板部２５の各接触片７１の先端部分における外側部分が変位抑制部６２に当接される。したがって、雌端子２４の接触片７１は、第１コネクタハウジング１０の変位抑制部６２によって端子板部１４から離間する方向への変位が抑制される。これにより、雌端子２４と雄端子５０の挿抜の繰り返し、意図しない過剰変位あるいは熱の付与によって雌端子２４にへたりが生じて接触片７１が端子板部１４から離間するような不具合を抑制でき、雄端子５０と雌端子２４との高い接続信頼性を維持させることができる。 On the other hand, according to the connector 1 according to the first embodiment, when the female terminal 24 is connected to the male terminal 50, the outer portion of the contact piece 71 of the contact plate portion 25 of the female terminal 24 is the outer portion. Is in contact with the displacement suppressing portion 62. Therefore, the contact piece 71 of the female terminal 24 is suppressed from being displaced in the direction away from the terminal plate portion 14 by the displacement suppressing portion 62 of the first connector housing 10. As a result, it is possible to suppress a problem that the female terminal 24 is repeatedly inserted and removed, the female terminal 24 is sagging due to unintended excessive displacement or heat is applied, and the contact piece 71 is separated from the terminal plate portion 14. , High connection reliability between the male terminal 50 and the female terminal 24 can be maintained.

そして、上記のコネクタ１からなる電源回路遮断装置によれば、接続信頼性の高い雄端子５０における一対の端子１３と雌端子２４とからなるメインスイッチ部ＭＳｗを備えるので、高い信頼性が得られる。 Further, according to the power supply circuit cutoff device including the connector 1, the main switch portion MSw including the pair of terminals 13 and the female terminals 24 in the male terminal 50 having high connection reliability is provided, so that high reliability can be obtained. ..

次に、本発明の他の実施形態に係るコネクタについて説明する。
図８は、本発明の第２実施形態に係るコネクタ１Ａの幅方向に沿う断面図である。なお、上記第１実施形態に係るコネクタ１の構成部材と略同様のコネクタ１Ａの構成部材については、同符号を付して詳細な説明を省略する。 Next, the connector according to another embodiment of the present invention will be described.
FIG. 8 is a cross-sectional view taken along the width direction of the connector 1A according to the second embodiment of the present invention. The components of the connector 1A which are substantially the same as the components of the connector 1 according to the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

図８に示すように、本第２実施形態に係るコネクタ１Ａは、触指防止壁６１における第２コネクタハウジング２０側である上端開口部が変位抑制部６２Ａとされている。即ち、このコネクタ１Ａでは、第１コネクタハウジング１０と第２コネクタハウジング２０とが嵌合されて、雄端子５０に雌端子２４が接続されると、雌端子２４の接点板部２５の各接触片７１における端子板部１４に接触する内側面と反対側の外側面が触指防止壁６１の上端開口部に設けられた変位抑制部６２Ａに当接する。 As shown in FIG. 8, in the connector 1A according to the second embodiment, the upper end opening on the second connector housing 20 side of the finger touch prevention wall 61 is a displacement suppressing portion 62A. That is, in this connector 1A, when the first connector housing 10 and the second connector housing 20 are fitted and the female terminal 24 is connected to the male terminal 50, each contact piece of the contact plate portion 25 of the female terminal 24 is connected. The outer surface of the 71 that is opposite to the inner surface that contacts the terminal plate portion 14 abuts on the displacement suppressing portion 62A provided at the upper end opening of the tactile prevention wall 61.

このコネクタ１Ａによれば、変位抑制部６２Ａが、一対の端子１３の端子板部１４をユーザが触るのを抑制する触指防止壁６１の上端開口部に設けられる。そこで、簡単な構造によって、雄端子５０を構成する一対の端子１３と雌端子２４との高い接続信頼性を維持させることができる。 According to the connector 1A, the displacement suppressing portion 62A is provided at the upper end opening of the tactile prevention wall 61 that prevents the user from touching the terminal plate portion 14 of the pair of terminals 13. Therefore, with a simple structure, it is possible to maintain high connection reliability between the pair of terminals 13 constituting the male terminal 50 and the female terminal 24.

図９は、本発明の第３実施形態に係るコネクタ１Ｂの幅方向に沿う断面図である。図１０は、図９に示したコネクタ１Ｂにおける嵌合時の状態を示す図であって、図１０の（ａ）及び図１０の（ｂ）はそれぞれ幅方向に沿う一部の断面図である。なお、上記第１実施形態に係るコネクタ１の構成部材と略同様のコネクタ１Ｂの構成部材については、同符号を付して詳細な説明を省略する。 FIG. 9 is a cross-sectional view taken along the width direction of the connector 1B according to the third embodiment of the present invention. 10 is a diagram showing a state at the time of fitting in the connector 1B shown in FIG. 9, and FIGS. 10A and 10B are partial cross-sectional views along the width direction, respectively. .. The components of the connector 1B which are substantially the same as the components of the connector 1 according to the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

図９に示すように、本第３実施形態に係るコネクタ１Ｂは、雄端子５０の端子板部１４と触指防止壁６１との間において雌端子２４の接触片７１の先端に当接する段部とされた変位抑制部６２Ｂが設けられている。この変位抑制部６２Ｂも、触指防止壁６１に一体に形成されている。 As shown in FIG. 9, the connector 1B according to the third embodiment has a stepped portion that abuts on the tip of the contact piece 71 of the female terminal 24 between the terminal plate portion 14 of the male terminal 50 and the tactile prevention wall 61. The displacement suppressing portion 62B is provided. The displacement suppressing portion 62B is also integrally formed with the tactile prevention wall 61.

図１０の（ａ）に示すように、コネクタ１Ｂにおいて、第１コネクタハウジング１０と第２コネクタハウジング２０とが嵌合され、図１０の（ｂ）に示すように、接触片７１の先端が変位抑制部６２Ｂである段部に突き当たると、接触片７１には、接続方向後方側である上方に向かう反力Ｆｕが付与される。ここで、接触片７１は、先端が端子板部１４に徐々に近づく方向から離間する方向へ屈曲部７２で屈曲されている。そこで、上方への変位が規制された雌端子２４の接触片７１では、付与された反力Ｆｕが接触片７１の接点である屈曲部７２を雄端子５０の端子板部１４側へ向かう押圧力Ｆｐとなり、雄端子５０の端子板部１４に対する接触片７１の接触圧が増加される。 As shown in FIG. 10A, the first connector housing 10 and the second connector housing 20 are fitted in the connector 1B, and the tip of the contact piece 71 is displaced as shown in FIG. 10B. When the contact piece 71 abuts on the step portion which is the restraining portion 62B, an upward reaction force Fu, which is on the rear side in the connection direction, is applied to the contact piece 71. Here, the contact piece 71 is bent at the bent portion 72 in a direction in which the tip thereof is gradually separated from the terminal plate portion 14. Therefore, in the contact piece 71 of the female terminal 24 whose upward displacement is restricted, the applied reaction force Fu pushes the bent portion 72, which is the contact point of the contact piece 71, toward the terminal plate portion 14 side of the male terminal 50. It becomes Fp, and the contact pressure of the contact piece 71 with respect to the terminal plate portion 14 of the male terminal 50 is increased.

このように、本第３実施形態に係るコネクタ１Ｂによれば、接触片７１の先端が変位抑制部６２Ｂである段部に当接し、接続方向後方側への反力Ｆｕを受けると、その反力Ｆｕが接触片７１の屈曲部７２を端子板部１４へ押圧付勢する押圧力Ｆｐとして付与される。これにより、接触片７１を端子板部１４へ確実に接触させることができ、雄端子５０を構成する一対の端子１３と雌端子２４との高い接続信頼性を維持させることができる。 As described above, according to the connector 1B according to the third embodiment, when the tip of the contact piece 71 comes into contact with the step portion which is the displacement suppressing portion 62B and receives the reaction force Fu toward the rear side in the connection direction, the reaction is received. The force Fu is applied as a pressing force Fp that presses and urges the bent portion 72 of the contact piece 71 against the terminal plate portion 14. As a result, the contact piece 71 can be reliably brought into contact with the terminal plate portion 14, and high connection reliability between the pair of terminals 13 constituting the male terminal 50 and the female terminal 24 can be maintained.

尚、本発明は、上述した実施形態に限定されるものではなく、適宜、変形、改良、等が可能である。その他、上述した実施形態における各構成要素の材質、形状、寸法、数、配置箇所、等は本発明を達成できるものであれば任意であり、限定されない。 The present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, and the like. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary as long as the present invention can be achieved, and are not limited.

例えば、上記実施形態では、電源回路遮断装置として用いられるコネクタを例に説明したが、本発明のコネクタはこれに限らない。第１コネクタハウジングに設けられ、第２コネクタハウジングとの嵌合方向に突設された板状の雄端子と、第２コネクタハウジングに設けられ、互いに対向位置に配置された一対の接触片を有する側面視略Ｕ字状の雌端子と、を備えたコネクタであれば、ジョイントコネクタ等の種々のコネクタに適用できることは云うまでもない。 For example, in the above embodiment, the connector used as the power supply circuit cutoff device has been described as an example, but the connector of the present invention is not limited to this. It has a plate-shaped male terminal provided in the first connector housing and projecting in the mating direction with the second connector housing, and a pair of contact pieces provided in the second connector housing and arranged at positions facing each other.
