Description

本発明は、半嵌合防止機能を備えたコネクタに関する。 The present invention relates to a connector having a half-fitting prevention function.

従来から、一対のコネクタが半嵌合状態であるときに、一方のコネクタに設けたスライド部材が他方のコネクタに当接して一方のコネクタから離間させるように付勢するものが知られている。この種のコネクタは半嵌合防止コネクタとして知られている。半嵌合防止コネクタによれば、一対のコネクタを嵌合する際に両コネクタの端子同士が正しく接続されていない半嵌合状態が発生するのを防ぐことができる。本出願人も過去に、スライド部材を用いた半嵌合防止コネクタを提案している。 Conventionally, when a pair of connectors are in a semi-fitted state, a slide member provided on one connector is urged so as to abut against the other connector and separate from the one connector. This type of connector is known as a semi-fitting prevention connector. According to the half-fitting prevention connector, it is possible to prevent a half-fitting state in which the terminals of both connectors are not properly connected when the pair of connectors are fitted. In the past, the present applicant has also proposed a half-fitting prevention connector using a slide member.

本出願人が提案した半嵌合防止コネクタでは、第１及び第２の２つのスライド部材が一方のコネクタに設けられる。各スライド部材は一方のコネクタに支持されて、他方のコネクタが嵌脱される方向にスライド可能に構成されている。両スライド部材間には、両スライド部材の接近離間によって拡縮するコイルばねが接続されている。 In the half-fitting prevention connector proposed by the present applicant, the first and second slide members are provided in one connector. Each slide member is supported by one connector, and is configured to be slidable in a direction in which the other connector is fitted and removed. A coil spring that expands and contracts by the approach and separation of the slide members is connected between the slide members.

そして、一方のコネクタに対する他方のコネクタの半嵌合状態では、他方のコネクタの端面が第１のスライド部材に当接して第１のスライド部材を押す。また、他方のコネクタの挿入により撓んだ一方のコネクタのロックアームが第２のスライド部材に係止される。ロックアームが係止された第２のスライド部材は、一方のコネクタに対してスライドできなくなる。 In the half-fitted state of the other connector with respect to one connector, the end surface of the other connector abuts on the first slide member and pushes the first slide member. Further, the lock arm of one connector bent by the insertion of the other connector is locked to the second slide member. The second slide member to which the lock arm is locked cannot slide with respect to one connector.

したがって、他方のコネクタに押された第１のスライド部材が第２のスライド部材から離間してコイルばねが伸長し、第１スライド部材を第２スライド部材に接近させる方向の付勢力がコイルばねに蓄積される。コイルばねに蓄積された付勢力は、第１スライド部材から他方のコネクタに伝わって、他方のコネクタを一方のコネクタから離間する方向に付勢する。 Accordingly, the first slide member pushed by the other connector is separated from the second slide member and the coil spring is extended, and the biasing force in the direction in which the first slide member approaches the second slide member is applied to the coil spring. Accumulated. The urging force accumulated in the coil spring is transmitted from the first slide member to the other connector, and urges the other connector in a direction away from the one connector.

これに対し、一方のコネクタに対する他方のコネクタの本嵌合状態では、一方のコネクタのロックアームが他方のコネクタの係止突起に係止されてロックアームの撓みが解消される。すると、第２のスライド部材に対するロックアームの係止が解消されて、第２のスライド部材が一方のコネクタに対してスライド可能となる。 On the other hand, in the main fitting state of the other connector with respect to one connector, the lock arm of one connector is locked by the locking protrusion of the other connector, and the bending of the lock arm is eliminated. Then, the locking of the lock arm with respect to the second slide member is canceled, and the second slide member can slide with respect to one connector.

スライド可能となった第２のスライド部材は、伸長していたコイルばねに蓄積された付勢力により、第１スライド部材に接近する方向にスライドする。第２スライド部材の第１スライド部材への接近により、伸長していたコイルばねが拡縮し、蓄積していた付勢力を解放した状態となる。 The slidable second slide member slides in a direction approaching the first slide member by the biasing force accumulated in the extended coil spring. When the second slide member approaches the first slide member, the extended coil spring expands and contracts, and the accumulated biasing force is released.

本出願人が提案した半嵌合防止コネクタでは、一方のコネクタに対する他方のコネクタの半嵌合状態のときに、２つのスライド部材間に接続したコイルばねからコネクタ間に加わる付勢力によりコネクタ同士が離間する方向に付勢される。よって、コネクタが半嵌合状態となった場合に両コネクタを離脱させて、半嵌合状態のまま放置されるのを防止することができる。 In the half-fitting prevention connector proposed by the present applicant, when the other connector is in a half-fitted state with respect to one connector, the connectors are connected by a biasing force applied between the connectors from the coil spring connected between the two slide members. It is biased in the direction of separating. Therefore, when the connectors are in the half-fitted state, it is possible to prevent both connectors from being detached and left in the half-fitted state.

また、両コネクタの端子同士が正しく接続された本嵌合状態では、第１のスライド部材の押し込みによりばねに蓄積された付勢力が、ロックアームの係止が解消された第２のスライド部材のスライドにより解放される。よって、半嵌合状態のときにばねに蓄積された付勢力が、本嵌合状態となった後にも引き続きばねに蓄積されたままとなって、ばねの劣化が進むのを、抑制することができる（以上、例えば特許文献１）。 Further, in the fully-fitted state in which the terminals of both connectors are correctly connected, the biasing force accumulated in the spring due to the pushing of the first slide member is applied to the second slide member in which the lock arm is released. Released by slide. Therefore, it is possible to suppress the urging force accumulated in the spring in the half-fitted state from being continuously accumulated in the spring even after the full-fitted state, thereby preventing the spring from deteriorating. (For example, Patent Document 1).

本発明は、上述した半嵌合防止コネクタで２つ必要としていたスライド部材を１つに減らして構成の簡略化を図ることを目的としている。 An object of the present invention is to simplify the configuration by reducing the number of slide members that are required in the half-fitting prevention connector described above to one.

上記目的を達成するために、本発明の第１の態様による半嵌合防止コネクタは、
内部にそれぞれ端子を備えた一対のコネクタと、
前記一対のコネクタのうち一方のコネクタに設けられ、前記一対のコネクタの前記端子同士が接続された本嵌合状態において、前記一対のコネクタのうち他方のコネクタの係止部に係止されるロックアームと、
前記他方のコネクタに設けられ、前記一対のコネクタの前記端子同士が接続される前の半嵌合状態において、前記他方のコネクタとの接触により撓み変形した前記ロックアームと干渉し、該ロックアームに押圧されて前記他方のコネクタに対し前記一方のコネクタの嵌合方向に移動すると共に、前記本嵌合状態において、前記係止部への係止により撓み変形が解消した前記ロックアームとの干渉が解消されるスライド部材と、
前記他方のコネクタに設けられ、前記他方のコネクタに対する前記スライド部材の前記嵌合方向への移動により、前記他方のコネクタに対して前記スライド部材を前記嵌合方向の逆方向に移動させる付勢力を蓄積する付勢部材と、
を備える。 In order to achieve the above object, a half-fitting prevention connector according to the first aspect of the present invention comprises
A pair of connectors each having a terminal therein;
A lock that is provided on one connector of the pair of connectors and is locked to a locking portion of the other connector of the pair of connectors in the main fitting state in which the terminals of the pair of connectors are connected to each other. Arm,
Provided in the other connector, in a half-fitted state before the terminals of the pair of connectors are connected to each other, interferes with the lock arm which is bent and deformed by contact with the other connector, and While being pressed and moved with respect to the other connector in the fitting direction of the one connector, in the main fitting state, there is interference with the lock arm in which the bending deformation is eliminated by the locking to the locking portion. A sliding member to be eliminated;
A biasing force that is provided on the other connector and moves the slide member in a direction opposite to the fitting direction relative to the other connector by moving the slide member in the fitting direction with respect to the other connector. A biasing member that accumulates;
Is provided.

本発明の第１の態様による半嵌合防止コネクタによれば、一方のコネクタを他方のコネクタに嵌合させる際、一方のコネクタのロックアームは、他方のコネクタとの接触により撓み変形して他方のコネクタのスライド部材と干渉する。ロックアームと干渉したスライド部材は、ロックアームにより押圧されて、他方のコネクタに対し嵌合方向に移動する。スライド部材が他方のコネクタに対し嵌合方向に移動すると、スライド部材を他方のコネクタに対し嵌合方向と逆方向に移動させる付勢力が付勢部材に蓄積される。 According to the half-fitting prevention connector according to the first aspect of the present invention, when one connector is fitted to the other connector, the lock arm of one connector is bent and deformed by contact with the other connector, and the other Interferes with the sliding member of the connector. The slide member that interferes with the lock arm is pressed by the lock arm and moves in the fitting direction with respect to the other connector. When the slide member moves in the fitting direction with respect to the other connector, a biasing force that moves the slide member with respect to the other connector in a direction opposite to the fitting direction is accumulated in the biasing member.

付勢部材に蓄積された付勢力は、一対のコネクタの端子同士が接続される前の半嵌合状態にあり、撓み変形したロックアームがスライド部材を押圧している間、スライド部材からロックーアームに反力として作用する。この反力は、半嵌合状態の一方のコネクタを他方のコネクタから嵌合方向の逆方向に離脱させる力として働き、一対のコネクタが半嵌合状態に維持されるのを防止する。 The urging force accumulated in the urging member is in a semi-fitted state before the terminals of the pair of connectors are connected to each other, and while the flexurally deformed lock arm presses the slide member, the slide member changes to the lock arm. Acts as a reaction force. This reaction force acts as a force that separates one connector in the half-fitted state from the other connector in the opposite direction of the fitting direction, and prevents the pair of connectors from being maintained in the half-fitted state.

付勢部材の付勢力を超える力で一方のコネクタが他方のコネクタに嵌合されて、ロックアームが他方のコネクタの係止部に係止されると、一対のコネクタの端子同士が接続されて本嵌合状態となる。一対のコネクタの本嵌合状態では、ロックアームの撓み変形が解消されて、スライド部材がロックアームと干渉しなくなる。 When one connector is fitted to the other connector with a force exceeding the urging force of the urging member and the lock arm is locked to the locking portion of the other connector, the terminals of the pair of connectors are connected to each other. It will be in this fitting state. In the fully fitted state of the pair of connectors, the bending deformation of the lock arm is eliminated, and the slide member does not interfere with the lock arm.

ロックアームと干渉しなくなったスライド部材は、ロックアームにより押圧されなくなるので、付勢部材に蓄積された付勢力は反力としてロックアームに伝わらなくなる。そして、ロックアームと干渉しなくなったスライド部材は、付勢部材に蓄積された付勢力によって、他方のコネクタに対し嵌合方向と逆方向に移動する。嵌合方向と逆方向へのスライド部材の移動により、付勢部材に蓄積された付勢力は解放される。したがって、本嵌合状態の一方のコネクタには、他方のコネクタから嵌合方向の逆方向に離脱させる力が働らかず、一対のコネクタは本嵌合状態に維持される。 Since the slide member that no longer interferes with the lock arm is not pressed by the lock arm, the urging force accumulated in the urging member is not transmitted to the lock arm as a reaction force. Then, the slide member that no longer interferes with the lock arm moves in the direction opposite to the fitting direction with respect to the other connector by the biasing force accumulated in the biasing member. The biasing force accumulated in the biasing member is released by the movement of the slide member in the direction opposite to the fitting direction. Accordingly, a force that causes the one connector in the fully fitted state to be detached from the other connector in the direction opposite to the fitting direction does not act, and the pair of connectors is maintained in the fully fitted state.

本発明の第１の態様による半嵌合防止コネクタは、以上の構成としたことから、一方のコネクタに対する他方のコネクタの半嵌合状態では、一対のコネクタ間に加わる付勢部材の付勢力により一対のコネクタ同士を離間させて、両コネクタが半嵌合状態で放置されるのを防止することができる。 Since the half-fitting prevention connector according to the first aspect of the present invention is configured as described above, in the half-fitted state of the other connector with respect to one connector, the biasing force of the biasing member applied between the pair of connectors is used. A pair of connectors can be separated from each other to prevent both connectors from being left in a half-fitted state.

また、一方のコネクタに対する他方のコネクタの本嵌合状態では、スライド部材の移動により付勢部材に蓄積される付勢力を解放して、付勢部材の付勢力の劣化が進むのを抑制することができる。 Further, in the fully-fitted state of the other connector with respect to the one connector, the biasing force accumulated in the biasing member is released by the movement of the slide member, and the progress of the deterioration of the biasing force of the biasing member is suppressed. Can do.

そして、両コネクタが半嵌合状態で放置されることの防止と、付勢部材の付勢力の劣化が進むことの抑制とを、単一のスライド部材を用いた簡略な構成によって実現することができる。 And it is possible to realize prevention of both connectors from being left in a half-fitted state and suppression of progress of deterioration of the urging force of the urging member with a simple configuration using a single slide member. it can.

また、本発明の第２の態様による半嵌合防止コネクタは、本発明の第１の態様による半嵌合防止コネクタにおいて、前記付勢部材は、前記他方のコネクタと前記スライド部材との間に架設されて該スライド部材の前記他方のコネクタに対する前記嵌合方向への移動により変形して復元力を蓄積するコイルばねである。 The half-fitting prevention connector according to the second aspect of the present invention is the half-fitting prevention connector according to the first aspect of the present invention, wherein the urging member is disposed between the other connector and the slide member. It is a coil spring that is installed and is deformed by the movement of the slide member in the fitting direction with respect to the other connector and accumulates a restoring force.

本発明の第２の態様による半嵌合防止コネクタによれば、本発明の第１の態様による半嵌合防止コネクタにおいて、他方のコネクタとスライド部材との間に付勢部材を架設する場合、付勢部材は、スライド部材の他方のコネクタに対する嵌合方向への移動により変形して復元力を蓄積するコイルばねとすることができる。 According to the half-fitting prevention connector according to the second aspect of the present invention, in the half-fitting prevention connector according to the first aspect of the present invention, when the urging member is installed between the other connector and the slide member, The urging member can be a coil spring that accumulates restoring force by being deformed by movement of the slide member in the fitting direction with respect to the other connector.

このコイルばねは、スライド部材の他方のコネクタに対する嵌合方向への移動により通常の状態よりも伸長して収縮方向への復元力を蓄積するものであってもよく、スライド部材の他方のコネクタに対する嵌合方向への移動により通常の状態よりも収縮して伸長方向への復元力を蓄積するものであってもよい。 The coil spring may be one that extends from the normal state by moving the slide member in the fitting direction with respect to the other connector and accumulates a restoring force in the contraction direction. You may accumulate | store the restoring force to an expansion | extension direction by shrink | contracting rather than a normal state by the movement to a fitting direction.

本発明によれば、一対のコネクタが半嵌合状態で放置されることの防止と、半嵌合防止用の付勢部材の付勢力が劣化することの抑制とを、単一のスライド部材を用いた簡略な構成によって実現することができる。 According to the present invention, it is possible to prevent the pair of connectors from being left in the half-fitted state and to suppress the deterioration of the urging force of the urging member for preventing the half-fitting. This can be realized by the simple configuration used.

A plurality of terminal insertion holes 19 are formed at the front end of the female terminal accommodating portion 15. Each terminal insertion hole 19 faces an opening at the tip of each female terminal 13 accommodated therein from the rear end of the female terminal accommodating portion 15.

ロックアーム１７は、図１に示すように、雌端子収容部１５の後端側で片持ち支持されている。ロックアーム１７の先端側は、雌端子収容部１５の上面から一定の間隔をおいた上方に、雌端子収容部１５の上面に沿って延出している。ロックアーム１７の先端には、係止突起２１が形成されている。 As shown in FIG. 1, the lock arm 17 is cantilevered on the rear end side of the female terminal accommodating portion 15. The distal end side of the lock arm 17 extends along the upper surface of the female terminal accommodating portion 15 upward from the upper surface of the female terminal accommodating portion 15 with a certain distance. A locking projection 21 is formed at the tip of the lock arm 17.

雄コネクタ３０は、雄ハウジング３１と雄端子３３（請求項中の他方のコネクタの端子に相当）とスライド部材３５とを有している。 The male connector 30 includes a male housing 31, a male terminal 33 (corresponding to a terminal of the other connector in the claims), and a slide member 35.

雄ハウジング３１は、雄端子収容部３７とフード部３９とを有している。フード部３９は、雌コネクタ１０が嵌合される雄ハウジング３１の前端側に配置されており、雄端子収容部３７は、雄ハウジング３１のフード部３９よりも後端側に配置されている。 The male housing 31 has a male terminal accommodating portion 37 and a hood portion 39. The hood portion 39 is disposed on the front end side of the male housing 31 to which the female connector 10 is fitted, and the male terminal housing portion 37 is disposed on the rear end side of the hood portion 39 of the male housing 31.

スライド部材３５は、雄ハウジング３１側の面にストッパ片４７を有している。このストッパ片４７と、雄ハウジング３１の後端のストッパ片４９とには、コイルばね５１（請求項中の付勢部材に相当）の両端が当接している。このコイルばね５１の弾発力（請求項中の復元力に相当）により、雌コネクタ１０の離脱方向Ｙ（雄ハウジング３１の前端側）に付勢されている。 The slide member 35 has a stopper piece 47 on the surface on the male housing 31 side. Both ends of a coil spring 51 (corresponding to an urging member in claims) are in contact with the stopper piece 47 and the stopper piece 49 at the rear end of the male housing 31. The spring force of the coil spring 51 (corresponding to a restoring force in claims) biases the female connector 10 in the detaching direction Y (the front end side of the male housing 31).

雌コネクタ１０と雄コネクタ３０とが半嵌合状態である間、撓み変形したロックアーム１７の係止突起２１は、ガイド溝４５に案内されて前後に移動するスライド部材３５の前端５３の移動軌跡上に位置する。 While the female connector 10 and the male connector 30 are in the half-fitted state, the locking projection 21 of the lock arm 17 that has been bent and deformed is guided by the guide groove 45 and moved along the front end 53 of the slide member 35 that moves back and forth. Located on the top.

そして、撓み変形したロックアーム１７の係止突起２１は、図５に示す、雌コネクタ１０の雌端子１３の先端に雄コネクタ３０の雄端子３３の先端が挿入され始める位置の手前で、スライド部材３５の前端５３に当接する。ここで、係止突起２１の形状は、ロックアーム１７が撓み変形した状態でスライド部材３５の前端５３に当接できる形状であれば、いかなる形状であってもよい。 Then, the locking projection 21 of the lock arm 17 which has been bent and deformed is a slide member before the position where the tip of the male terminal 33 of the male connector 30 begins to be inserted into the tip of the female terminal 13 of the female connector 10 shown in FIG. 35 abuts on the front end 53 of the plate. Here, the shape of the locking protrusion 21 may be any shape as long as it can contact the front end 53 of the slide member 35 in a state where the lock arm 17 is bent and deformed.

なお、ロックアーム１７の係止突起２１は、図６に示すように、雌コネクタ１０と雄コネクタ３０とが本嵌合状態となり、係止突起２１が雄ハウジング３１の係止溝４１に係止されて、ロックアーム１７の撓み変形が解消される位置まで、スライド部材３５の前端５３に当接する。 As shown in FIG. 6, the locking projection 21 of the lock arm 17 is in a fully fitted state between the female connector 10 and the male connector 30, and the locking projection 21 is locked in the locking groove 41 of the male housing 31. Then, it abuts on the front end 53 of the slide member 35 to a position where the bending deformation of the lock arm 17 is eliminated.

そして、ロックアーム１７の係止突起２１が前端５３に当接したスライド部材３５は、雌コネクタ１０と雄コネクタ３０とが半嵌合状態となる位置関係にあるときに、雌コネクタ１０の雄コネクタ３０に対する嵌合度合いに応じたストロークで、移動範囲の後端側（嵌合方向Ｘ）に移動する。 The slide member 35 in which the locking projection 21 of the lock arm 17 is in contact with the front end 53 is in a positional relationship where the female connector 10 and the male connector 30 are in a semi-fitted state. It moves to the rear end side (fitting direction X) of the moving range with a stroke corresponding to the degree of fitting with respect to 30.

スライド部材３５が移動範囲の後端側に移動すると、スライド部材３５と雄ハウジング３１の両ストッパ片４７，４９の間隔が縮まってコイルばね５１が収縮し、スライド部材３５の移動ストロークに応じた弾発力がコイルばね５１に蓄積される。したがって、スライド部材３５がロックアーム１７に押されて雄ハウジング３１の後端側に移動するほど、コイルばね５１の弾発力によりスライド部材３５に加わる離脱方向Ｙへの付勢力が増加する。 When the slide member 35 moves to the rear end side of the moving range, the distance between the slide member 35 and the stopper pieces 47 and 49 of the male housing 31 is shortened, the coil spring 51 is contracted, and the elastic member according to the moving stroke of the slide member 35 is contracted. The generated force is accumulated in the coil spring 51. Therefore, as the slide member 35 is pushed by the lock arm 17 and moves to the rear end side of the male housing 31, the biasing force in the separation direction Y applied to the slide member 35 by the elastic force of the coil spring 51 increases.

雌コネクタ１０と雄コネクタ３０とが本嵌合状態となり、係止突起２１が係止溝４１に係止されてロックアーム１７の撓み変形が解消されると、スライド部材３５の前端５３に当接していたロックアーム１７の係止突起２１が、スライド部材３５の前端５３の移動軌跡上から退避する。すると、図７の断面図に示すように、コイルばね５１からの付勢力でスライド部材３５が移動範囲の前端に移動し、コイルばね５１に蓄積された弾発力が解放される。 When the female connector 10 and the male connector 30 are in the final fitting state, and the locking protrusion 21 is locked in the locking groove 41 and the bending deformation of the lock arm 17 is eliminated, the female connector 10 contacts the front end 53 of the slide member 35. The locking protrusion 21 of the lock arm 17 that has been retracted from the movement locus of the front end 53 of the slide member 35. Then, as shown in the sectional view of FIG. 7, the sliding member 35 moves to the front end of the moving range by the urging force from the coil spring 51, and the elastic force accumulated in the coil spring 51 is released.

次に、上述したように構成された本実施形態の半嵌合防止コネクタ１の作用について説明する。 Next, the operation of the half-fitting prevention connector 1 of the present embodiment configured as described above will be described.

雌コネクタ１０を雄コネクタ３０に嵌合する際には、まず、図３に示すように、雌ハウジング１１の雌端子収容部１５を雄ハウジング３１のフード部３９に挿入する。この挿入の初期に、図４に示すように、雌コネクタ１０のロックアーム１７の係止突起２１がフード部３９の上面に乗り上げて、雌コネクタ１０のロックアーム１７が撓み変形する。フード部３９に乗り上げた係止突起２１は、スライド部材３５の前端５３の移動軌跡上に進出する。 When fitting the female connector 10 to the male connector 30, first, as shown in FIG. 3, the female terminal accommodating portion 15 of the female housing 11 is inserted into the hood portion 39 of the male housing 31. At the initial stage of the insertion, as shown in FIG. 4, the locking projection 21 of the lock arm 17 of the female connector 10 rides on the upper surface of the hood portion 39, and the lock arm 17 of the female connector 10 is bent and deformed. The locking protrusion 21 riding on the hood portion 39 advances on the movement locus of the front end 53 of the slide member 35.

雌ハウジング１１の雌端子収容部１５を雄ハウジング３１のフード部３９にさらに挿入すると、係止突起２１がスライド部材３５の前端５３に当接する。また、図５に示すように、雌コネクタ１０の雌端子１３の先端に雄コネクタ３０の雄端子３３の先端が挿入され始める。この挿入開始により、雌コネクタ１０と雄コネクタ３０とが半嵌合状態となる。 When the female terminal accommodating portion 15 of the female housing 11 is further inserted into the hood portion 39 of the male housing 31, the locking projection 21 comes into contact with the front end 53 of the slide member 35. Further, as shown in FIG. 5, the leading end of the male terminal 33 of the male connector 30 starts to be inserted into the leading end of the female terminal 13 of the female connector 10. By starting the insertion, the female connector 10 and the male connector 30 are in a semi-fitted state.

また、雄端子３３が雌端子１３に挿入され始めると、係止突起２１が前端５３に当接したロックアーム１７によりスライド部材３５が押されて、移動範囲の後端側に移動する。この移動によりコイルばね５１が収縮し、スライド部材３５の移動ストロークに応じた弾発力がコイルばね５１に蓄積される。この弾発力は、離脱方向Ｙへの付勢力としてスライド部材３５に加わる。 When the male terminal 33 starts to be inserted into the female terminal 13, the slide member 35 is pushed by the lock arm 17 in which the locking projection 21 is in contact with the front end 53, and moves to the rear end side of the movement range. By this movement, the coil spring 51 contracts, and an elastic force corresponding to the movement stroke of the slide member 35 is accumulated in the coil spring 51. This elastic force is applied to the slide member 35 as a biasing force in the separation direction Y.

雄端子３３が雌端子１３に挿入され始めた位置で、コイルばね５１からスライド部材３５に加わる付勢力は、スライド部材３５に当接したロックアーム１７を有する雌コネクタ１０を、スライド部材３５と共に離脱方向Ｙに押し返すのに十分な大きさである。 The biasing force applied to the slide member 35 from the coil spring 51 at the position where the male terminal 33 starts to be inserted into the female terminal 13 causes the female connector 10 having the lock arm 17 in contact with the slide member 35 to be detached together with the slide member 35. Large enough to push back in direction Y.

このため、雄端子３３が雌端子１３に挿入され始めた位置で、半嵌合状態のまま雄コネクタ３０に対する雌コネクタ１０の嵌合作業を中止すると、コイルばね５１からの付勢力でスライド部材３５が雌コネクタ１０を離脱方向Ｙに押し返す。この押し返しにより、雌端子１３に挿入され始めた雄端子３３が雌端子１３から離間して、雌コネクタ１０と雄コネクタ３０とが離脱する。 For this reason, when the fitting operation of the female connector 10 with respect to the male connector 30 is stopped in the half-fitted state at the position where the male terminal 33 starts to be inserted into the female terminal 13, the slide member 35 is urged by the urging force from the coil spring 51. Pushes back the female connector 10 in the detaching direction Y. By this pushing back, the male terminal 33 which has started to be inserted into the female terminal 13 is separated from the female terminal 13 and the female connector 10 and the male connector 30 are detached.

一方、雄端子３３が雌端子１３に挿入され始めた位置から、雌ハウジング１１の雌端子収容部１５を雄ハウジング３１のフード部３９にさらに挿入すると、雌端子１３に対して雄端子３３が一部挿入される。この挿入により、雌端子１３と雄端子３３との間には摩擦抵抗が働くようになる。この摩擦抵抗により、雌コネクタ１０と雄コネクタ３０とは、嵌合作業を中止しても半嵌合状態のまま保持されやすくなる。 On the other hand, when the female terminal accommodating portion 15 of the female housing 11 is further inserted into the hood portion 39 of the male housing 31 from the position where the male terminal 33 has started to be inserted into the female terminal 13, the male terminal 33 is one in the female terminal 13. Part inserted. As a result of this insertion, a frictional resistance acts between the female terminal 13 and the male terminal 33. Due to this frictional resistance, the female connector 10 and the male connector 30 are easily held in a semi-fitted state even when the fitting operation is stopped.

また、雌端子収容部１５をフード部３９にさらに挿入すると、ロックアーム１７によりスライド部材３５がさらに押されて、移動範囲のさらに後端側に移動する。この移動により、コイルばね５１はスライド部材３５の移動分だけさらに収縮する。この収縮により、コイルばね５１に蓄積される弾発力は、スライド部材３５の増加した移動ストロークに応じた大きさに増える。したがって、離脱方向Ｙへの付勢力としてコイルばね５１からスライド部材３５に加わる付勢力も増える。 Further, when the female terminal accommodating portion 15 is further inserted into the hood portion 39, the slide member 35 is further pushed by the lock arm 17 and moves further to the rear end side of the moving range. By this movement, the coil spring 51 is further contracted by the amount of movement of the slide member 35. Due to this contraction, the elastic force accumulated in the coil spring 51 increases to a magnitude corresponding to the increased movement stroke of the slide member 35. Therefore, the biasing force applied from the coil spring 51 to the slide member 35 as the biasing force in the separation direction Y also increases.

雌端子１３に対して雄端子３３が一部挿入された位置で、コイルばね５１からスライド部材３５に加わる付勢力は、雌端子１３に挿入された雄端子３３を摩擦抵抗に抗して雌端子１３から抜脱させ、雌コネクタ１０を離脱方向Ｙに押し返すのに十分な大きさである。 The biasing force applied from the coil spring 51 to the slide member 35 at the position where the male terminal 33 is partially inserted into the female terminal 13 causes the male terminal 33 inserted into the female terminal 13 to resist the frictional resistance. It is large enough to be removed from 13 and to push back the female connector 10 in the detaching direction Y.

このため、雄端子３３が雌端子１３に一部挿入された位置で、半嵌合状態のまま雄コネクタ３０に対する雌コネクタ１０の嵌合作業を中止した場合にも、コイルばね５１からの付勢力でスライド部材３５が雌コネクタ１０を離脱方向Ｙに押し返す。この押し返しにより、雌コネクタ１０と雄コネクタ３０とが離脱する。 For this reason, even when the fitting operation of the female connector 10 with respect to the male connector 30 is stopped in the half-fitted state at the position where the male terminal 33 is partially inserted into the female terminal 13, the biasing force from the coil spring 51 is stopped. Then, the slide member 35 pushes the female connector 10 back in the detaching direction Y. By this pushing back, the female connector 10 and the male connector 30 are detached.

雄端子３３が雌端子１３に一部挿入された後、ロックアーム１７の係止突起２１が雄ハウジング３１の係止溝４１に係止されるまで雌端子収容部１５をフード部３９にさらに挿入すると、雌コネクタ１０と雄コネクタ３０とが本嵌合状態となる。この状態では、図６に示すように、ロックアーム１７の撓み変形が解消される。この解消により、係止突起２１がスライド部材３５の前端５３の移動軌跡上から退避する。 After the male terminal 33 is partially inserted into the female terminal 13, the female terminal accommodating portion 15 is further inserted into the hood portion 39 until the locking protrusion 21 of the lock arm 17 is locked to the locking groove 41 of the male housing 31. Then, the female connector 10 and the male connector 30 are in a fully fitted state. In this state, the bending deformation of the lock arm 17 is eliminated as shown in FIG. As a result of this cancellation, the locking projection 21 retreats from the movement locus of the front end 53 of the slide member 35.

スライド部材３５の前端５３の移動軌跡上から係止突起２１が退避すると、スライド部材３５がロックアーム１７により移動範囲の後端側（嵌合方向Ｘ）に押されなくなり、スライド部材３５が移動範囲の前端側に移動可能となる。このため、移動範囲の後端側へのスライド部材３５の移動により弾発力を蓄積したコイルばね５１が弾発力を解放し、図７に示すように、スライド部材３５を離脱方向Ｙに押し返して移動範囲の前端側に移動させる。 When the locking projection 21 is retracted from the movement trajectory of the front end 53 of the slide member 35, the slide member 35 is not pushed to the rear end side (the fitting direction X) by the lock arm 17 and the slide member 35 is moved. It becomes possible to move to the front end side. For this reason, the coil spring 51 that has accumulated the elastic force due to the movement of the slide member 35 toward the rear end side of the movement range releases the elastic force, and pushes the slide member 35 back in the disengaging direction Y as shown in FIG. To move to the front end of the moving range.

スライド部材３５が移動範囲の前端に移動すると、雄ハウジング３１の係止溝４１との係止を係止突起２１が解除する方向へのロックアーム１７の撓み変形がスライド部材３５によって規制され、雌コネクタ１０と雄コネクタ３０とが本嵌合状態に保持される。 When the slide member 35 moves to the front end of the moving range, the bending deformation of the lock arm 17 in the direction in which the locking projection 21 releases the locking with the locking groove 41 of the male housing 31 is regulated by the sliding member 35. The connector 10 and the male connector 30 are held in the fully fitted state.

なお、本嵌合状態の雌コネクタ１０と雄コネクタ３０とを離脱させる場合は、図７に示す状態から、コイルばね５１の弾発力に抗してスライド部材３５を移動範囲の後端に移動させる。さらに、ロックアーム１７を撓み変形させて係止突起２１と雄ハウジング３１の係止溝４１との係止を解除させる。そして、雌コネクタ１０を雄コネクタ３０に対して離脱方向Ｙに移動させればよい。 When the female connector 10 and the male connector 30 in the fully fitted state are separated, the slide member 35 is moved to the rear end of the movement range against the elastic force of the coil spring 51 from the state shown in FIG. Let Further, the locking arm 17 is bent and deformed to release the locking between the locking projection 21 and the locking groove 41 of the male housing 31. Then, the female connector 10 may be moved in the detaching direction Y with respect to the male connector 30.

以上に説明した本実施形態の半嵌合防止コネクタ１では、雌コネクタ１０と雄コネクタ３０とが本嵌合した際に、半嵌合状態の雌コネクタ１０を雄コネクタ３０から離脱させるためにコイルばね５１に蓄積された弾発力が、スライド部材３５のスライドで解放される。このため、雌コネクタ１０と雄コネクタ３０とが半嵌合状態で放置されることの防止と、コイルばね５１が長く収縮状態に保持されて弾発力が劣化することの抑制とを、単一のスライド部材３５を用いた簡略な構成によって実現することができる。 In the half-fitting prevention connector 1 of the present embodiment described above, a coil is used to separate the half-fitted female connector 10 from the male connector 30 when the female connector 10 and the male connector 30 are fully fitted. The elastic force accumulated in the spring 51 is released by the slide of the slide member 35. For this reason, it is possible to prevent the female connector 10 and the male connector 30 from being left in the half-fitted state, and to suppress the coil spring 51 from being held in the contracted state for a long time and the deterioration of the elastic force. This can be realized by a simple configuration using the slide member 35.

なお、本実施形態では、雌コネクタ１０と雄コネクタ３０との本嵌合状態においてロックアーム１７が係止される係止部として、雄ハウジング３１に係止溝４１（凹部）を設け、係止溝４１に係止される係止突起２１（凸部）をロックアーム１７に設けた。しかし、雄ハウジング３１に係止部として凸部を設け、これに係止可能な凹部をロックアーム１７に設けても良い。その場合、ロックアーム１７は、雌コネクタ１０と雄コネクタ３０との半嵌合状態において、雄ハウジング３１の前端に乗り上げて撓み変形するように構成しても良い。 In the present embodiment, a locking groove 41 (recessed portion) is provided in the male housing 31 as a locking portion to which the lock arm 17 is locked in the main fitting state of the female connector 10 and the male connector 30. Locking protrusions 21 (projections) that are locked in the grooves 41 are provided on the lock arm 17. However, the male housing 31 may be provided with a convex portion as a locking portion, and a concave portion that can be locked thereto is provided in the lock arm 17. In that case, the lock arm 17 may be configured to ride on the front end of the male housing 31 and bend and deform in a half-fitted state of the female connector 10 and the male connector 30.

また、本実施形態では、ロックアーム１７を雌コネクタ１０の雌ハウジング１１に設け、スライド部材３５を雄コネクタ３０の雄ハウジング３１に設けたが、雌コネクタ１０側にスライド部材を設け、雄コネクタ３０側にロックアームを設けても良い。 In this embodiment, the lock arm 17 is provided in the female housing 11 of the female connector 10 and the slide member 35 is provided in the male housing 31 of the male connector 30. However, the slide member is provided on the female connector 10 side, and the male connector 30 is provided. A lock arm may be provided on the side.

さらに、本実施形態では、雌コネクタ１０と雄コネクタ３０との半嵌合状態においてコイルばね５１が収縮して、スライド部材３５を離脱方向Ｙに付勢するための弾発力を蓄積するものとした。しかし、雌コネクタ１０と雄コネクタ３０との半嵌合状態においてコイルばねが引張されて、スライド部材３５を離脱方向Ｙに付勢するための復元力を蓄積するように構成しても良い。 Furthermore, in this embodiment, the coil spring 51 contracts in a half-fitted state between the female connector 10 and the male connector 30 and accumulates a resilient force for biasing the slide member 35 in the detaching direction Y. did. However, the coil spring may be pulled in a half-fitted state between the female connector 10 and the male connector 30 to accumulate a restoring force for urging the slide member 35 in the detaching direction Y.

また、半嵌合防止コネクタに設けるロックアームとスライド部材は、本実施形態の半嵌合防止コネクタ１のように一組であっても良く、複数組であっても良い。 Further, the lock arm and the slide member provided in the half-fitting prevention connector may be one set as in the half-fitting prevention connector 1 of this embodiment, or a plurality of sets.
