Description

本発明は、コネクタに関する。 The present invention relates to a connector.

特許文献１には、ロックアームを有する雌コネクタハウジングと、ロックアームに対して前進位置（待機位置）と後退位置（検知位置）とに移動可能に組み付けられるスライダ（検知部材）とを備えた雌コネクタが開示されている。スライダは、雌コネクタハウジングが相手側の雄コネクタハウジングと正規嵌合されるまでは前進位置に留め置かれ、両コネクタハウジングが正規嵌合されるに伴ってバネに付勢されて後退位置に移動させられるようになっている。したがって、スライダが後退位置に至ることをもって、両コネクタハウジングが正規嵌合されたと判断することができる。 Patent Document 1 discloses a female connector housing having a lock arm and a slider (detection member) that is movably assembled to a forward position (standby position) and a backward position (detection position) with respect to the lock arm. A connector is disclosed. The slider is held in the forward position until the female connector housing is properly mated with the mating male connector housing, and is moved to the retracted position by being biased by a spring as both connector housings are properly mated. It is supposed to be made. Therefore, when the slider reaches the retracted position, it can be determined that the two connector housings are properly fitted.

ここで、スライダには主ストッパ部が突出して設けられている。スライダが前進位置にあるときに、主ストッパ部がロックアームの係止孔に嵌合して係止されることにより、スライダが後退位置に移動するのが規制されるようになっている。 Here, a main stopper portion projects from the slider. When the slider is in the forward position, the main stopper is fitted and locked in the locking hole of the lock arm, thereby restricting the slider from moving to the backward position.

特許第４４１９８７５号公報Japanese Patent No. 4419885

ところで、両コネクタハウジングの嵌合過程で、ロックアームが撓み変形したときに、何らかの外力が作用すると、主ストッパ部が係止孔から抜け出て、主ストッパ部と係止孔との係止が不用意に外れることがある。仮に、両コネクタハウジングが正規嵌合される前に、主ストッパ部と係止孔との係止が外れると、スライダがバネで付勢されて後退位置に至ることになるため、嵌合検知の信頼性が低下するおそれがあった。 By the way, when the lock arm is bent and deformed in the fitting process of the two connector housings, if any external force is applied, the main stopper portion comes out of the locking hole, and the locking between the main stopper portion and the locking hole is not achieved. May be out of luck. If the locking between the main stopper and the locking hole is released before the two connector housings are properly fitted, the slider is biased by the spring and reaches the retracted position. There was a risk that reliability would be reduced.

本発明は上記のような事情に基づいて完成されたものであって、嵌合検知の信頼性を向上させたコネクタを提供することを目的とする。 The present invention has been completed based on the above circumstances, and an object of the present invention is to provide a connector with improved fitting detection reliability.

本発明のコネクタは、相手ハウジングに嵌合可能なハウジングと、前記ハウジングに対して待機位置と検知位置とに移動可能に組み付けられ、両ハウジングが正規嵌合されるまでは前記待機位置に留め置かれ、前記両ハウジングが正規嵌合されることで前記検知位置への移動が許容される検知部材とを備え、前記ハウジングには係止受部が設けられ、前記検知部材には前記待機位置で前記係止受部に係止可能な係止面を有することによって前記検知部材の前記検知位置への移動を規制する係止部が設けられ、前記係止面の一部には、前記待機位置にて、前記検知部材の移動方向と直交し且つ前記係止部が前記係止受部との係止を外す方向で前記係止受部と当接可能に対向する係止面部が設けられ、前記係止面部が前記係止部に設けられた突出部の突出端面に構成され、前記係止受部には、前記検知部材が前記待機位置にあるときに前記突出部が進入する凹部が設けられているところに特徴を有する。 The connector of the present invention is assembled in a housing that can be fitted into a mating housing, and is movably assembled to a standby position and a detection position with respect to the housing, and remains in the standby position until both housings are properly fitted. And a detection member that is allowed to move to the detection position when the two housings are properly fitted, and the housing is provided with a latch receiving portion, and the detection member is in the standby position. A locking portion that restricts movement of the detection member to the detection position by having a locking surface that can be locked to the locking receiving portion is provided, and a part of the locking surface includes the standby position. A locking surface portion that is orthogonal to the moving direction of the detection member and that faces the locking receiving portion in a direction in which the locking portion releases the locking with the locking receiving portion is provided , Protrusion where the locking surface portion is provided in the locking portion Is configured of a protrusion end face, with the locking receiving portion has characterized in that the sensing member has recesses in which the protruding portion enters is provided when in the standby position.

仮に、両ハウジングが正規嵌合されるまでの間に、何らかの外力が作用して係止部が係止受部との係止を外す方向に変位しようとしても、係止部の係止面部に係止受部が当接することにより、係止部と係止受部との係止が維持されるため、待機位置にある検知部材が不用意に検知位置に至るのが防止される。その結果、検知部材による嵌合検知の信頼性を向上させることができる。 Even if both external housings are engaged with each other and the locking part is about to displace in the direction of releasing the locking with the locking receiving part until both housings are properly fitted, Since the engagement between the engagement receiving portion and the engagement receiving portion is maintained by the contact of the engagement receiving portion, the detection member in the standby position is prevented from inadvertently reaching the detection position. As a result, the reliability of the fitting detection by the detection member can be improved.

また、係止面部が係止部の係止面の一部に設けられるに過ぎないため、係止面部を金型成形するに際し、検知部材に、金型の通過に起因して大きな型抜き孔が形成されるのが防止される。また、突出部が凹部に進入することにより、係止受部に対する係止部の遊動が規制されるため、検知部材が待機位置にあるときに、係止部と係止受部との係止がより安定に維持される。 In addition, since the locking surface portion is only provided on a part of the locking surface of the locking portion, when the locking surface portion is molded, a large punching hole is caused in the detection member due to the passage of the mold. Is prevented from forming. Further, since the protrusion moves into the recess, the movement of the locking portion with respect to the locking receiving portion is restricted, so that the locking portion and the locking receiving portion are locked when the detection member is in the standby position. Is maintained more stably.

本発明の好ましい形態を以下に示す。
前記検知部材には、前記両ハウジングの嵌合過程では前記相手ハウジングに押圧されて付勢力が蓄勢され、前記両ハウジングが正規嵌合されるに伴い前記付勢力が解放されて前記検知部材の前記検知位置への移動を付勢する付勢部材が設けられている。これによれば、両ハウジングの嵌合過程で付勢部材の付勢力が偶発的に解放され、検知部材が検知位置に不用意に移動させられる可能性があるため、上記係止面部によって検知部材の不用意な移動を防止することの意義が大となる。 Preferred embodiments of the present invention are shown below.
In the fitting process of the two housings, the detecting member is pressed against the mating housing to accumulate an urging force, and the urging force is released as the two housings are normally fitted to each other. A biasing member that biases the movement to the detection position is provided. According to this, since the urging force of the urging member is accidentally released during the fitting process of the two housings, and the detection member may be inadvertently moved to the detection position, the detection surface portion detects the detection member. The significance of preventing inadvertent movement is greatly increased.

前記検知部材の移動方向と直交し且つ前記係止部が前記係止受部との係止を外す方向を上方とし、前記検知部材が前記待機位置から前記検知位置に向かう方向を前方とした場合に、前記係止面部が上方に行くに従い前方に傾斜する形態になっている。これによれば、検知部材の検知位置への移動が係止面部によってより確実に防止される。 When the direction perpendicular to the moving direction of the detection member and the locking portion releases the lock with the lock receiving portion is upward, and the direction from the standby position toward the detection position is the forward direction In addition, the locking surface portion is inclined forward as it goes upward. According to this, the movement to the detection position of a detection member is prevented more reliably by the latching surface part.

The urging member 40 is composed of a spring such as a compression coil spring that can be expanded and contracted in the front-rear direction, and both front and rear ends thereof are supported by the urging member accommodating portion 63. As shown in FIG. 12, an assembly port 70 for assembling the urging member 40 is provided in the lower surface of the urging member accommodating portion 63 so as to be opened. Further, a retaining protrusion 77 is provided on the lower surface of the urging member accommodating portion 63 behind the assembly port 70. When the detection member 60 is in the detection position, the retaining protrusion 77 is locked to a retaining portion (not shown) of the housing 10 so that the detection member 60 is prevented from dropping from the housing 10. ing.

図９に示すように、操作アーム６６は、架設部６５の幅方向中央部（幅方向両端部を除く部分）に構成された支点部４９と、支点部４９から後方に大きく突出する幅広の操作部４８と、支点部４９から前方に小さく突出する幅狭の移動規制部４７とからなり、支点部４９を中心として操作部４８及び移動規制部４７が上下動する向きにシーソ状に揺動可能とされている。操作部４８は、平面視略矩形の平板状をなし、その後端部に、幅方向に沿った突条部４６を有している。検知部材６０の移動操作時には、突条部４６に、作業者の指を引っ掛けることが可能とされている。 As shown in FIG. 9, the operation arm 66 includes a fulcrum part 49 formed at the center in the width direction of the erection part 65 (a part excluding both ends in the width direction), and a wide operation that largely protrudes backward from the fulcrum part 49. And a narrow movement restricting portion 47 that protrudes forward from the fulcrum portion 49, and can swing in a seesaw shape so that the operation portion 48 and the movement restricting portion 47 move up and down around the fulcrum portion 49. It is said that. The operation part 48 has a substantially rectangular flat plate shape in plan view, and has a ridge 46 along the width direction at the rear end. When the detection member 60 is moved, the operator's finger can be hooked on the protrusion 46.

図６に示すように、移動規制部４７は、支点部４９から前方へ真っ直ぐ突出したあと前下がりに湾曲状に屈曲する形態になっている。移動規制部４７の前端部（突出端部）には、下向きに鋭角に突き出る規制端部４５が設けられている。規制端部４５の前面は、下方へ行くに従って前方へ突き出るように傾斜する規制面４４とされている。検知部材６０が検知位置にあるときに、移動規制部４７が移動規制受部２６の受溝２７に進入し、規制端部４５が受溝２７の前端角部３２に沿うようにして、規制面４４が受溝２７の規制受面２８に前後方向で対面して配置される。 As shown in FIG. 6, the movement restricting portion 47 is configured to bend in a curved shape in a forward downward direction after projecting straight forward from the fulcrum portion 49. The front end portion (projecting end portion) of the movement restricting portion 47 is provided with a restricting end portion 45 that protrudes downward at an acute angle. The front surface of the restriction end 45 is a restriction surface 44 that is inclined so as to protrude forward as it goes downward. When the detection member 60 is in the detection position, the movement restricting portion 47 enters the receiving groove 27 of the movement restricting receiving portion 26 and the restricting end 45 is along the front end corner portion 32 of the receiving groove 27 so that the restricting surface 44 is arranged facing the regulation receiving surface 28 of the receiving groove 27 in the front-rear direction.

次に、本実施例のコネクタの作用を説明する。
両ハウジング１０、８０の嵌合に先立ち、検知部材６０がハウジング１０に後方から組み込まれて待機位置に至らしめられる。待機位置では、係止アーム６２がロックアーム１６のロック孔１９に弾性的に進入し、係止アーム６２の前端がロック孔１９のロック面２１に当接可能に配置されるとともに（図１を参照）、係止部６８の係止面７４が係止受部２２の係止受面２４に当接可能に配置される（図２を参照）。これにより、検知部材６０が待機位置にて前後方向への移動を規制された状態に保持される。 Next, the operation of the connector of this embodiment will be described.
Prior to the fitting of the two housings 10 and 80, the detection member 60 is assembled into the housing 10 from the rear to reach the standby position. In the standby position, the locking arm 62 elastically enters the lock hole 19 of the lock arm 16 and the front end of the locking arm 62 is disposed so as to be able to contact the lock surface 21 of the lock hole 19 (see FIG. 1). The locking surface 74 of the locking portion 68 is arranged so as to be able to contact the locking receiving surface 24 of the locking receiving portion 22 (see FIG. 2). Accordingly, the detection member 60 is held in a state where movement in the front-rear direction is restricted at the standby position.

また、図２に示すように、待機位置では、係止部６８の突出部７２が係止受部２２の凹部２３に進入し、突出部７２の係止面部７５が係止受部２２の係止受面部２５に対面して当接可能に配置される。このとき、係止面部７５が係止受面部２５を上方（検知部材６０の移動方向と直交する方向で且つ係止部６８が係止受部２２との係止を外す方向）から臨むように配置される。したがって、係止アーム６２がロックアーム１６に対して上方へ持ち上げられる方向に撓み変形しようとすると、係止面部７５が係止受面部２５に当接することで係止アーム６２のそれ以上の撓み動作が規制される。その結果、係止部６８がロック孔１９から不用意に抜け出るのが防止され、検知部材６０がハウジング１０に対して待機位置に安定して保持される。 In addition, as shown in FIG. 2, in the standby position, the protruding portion 72 of the locking portion 68 enters the concave portion 23 of the locking receiving portion 22, and the locking surface portion 75 of the protruding portion 72 is engaged with the locking receiving portion 22. It arrange | positions so that it may contact and contact the stop surface part 25. FIG. At this time, the locking surface portion 75 faces the locking receiving surface portion 25 from above (the direction orthogonal to the moving direction of the detection member 60 and the locking portion 68 unlocking the locking receiving portion 22). Be placed. Accordingly, when the locking arm 62 is bent and deformed in the direction of being lifted upward with respect to the lock arm 16, the locking surface portion 75 abuts on the locking receiving surface portion 25, whereby the locking arm 62 is further bent. Is regulated. As a result, the locking portion 68 is prevented from inadvertently coming out of the lock hole 19, and the detection member 60 is stably held at the standby position with respect to the housing 10.

上記の状態で、ハウジング１０のハウジング本体１１が相手ハウジング８０のフード部８２内に嵌合される。嵌合の過程では、図３に示すように、ロック部８３の突片部８５の斜面がロックアーム１６のアーム本体部１８の前端部を摺動して、アーム本体部１８の前端部が上方へ持ち上げられる方向にロックアーム１６が撓み変形させられる。このとき、係止アーム６２もロックアーム１６に連動して一体に撓み変形させられる。両ハウジング１０、８０が正規嵌合されるまでの間、突片部８５が係止部６８の逃げ溝７３に進入して逃がされることにより、ロック部８３が係止部６８と当接するのが回避される。また、嵌合の過程では、詳細は図示しないが、付勢部材４０が相手ハウジング８０に押圧されて弾縮させられ、付勢部材４０に付勢力が蓄勢される。 In the above state, the housing main body 11 of the housing 10 is fitted into the hood portion 82 of the mating housing 80. In the process of fitting, as shown in FIG. 3, the slope of the projecting piece 85 of the lock portion 83 slides on the front end portion of the arm main body portion 18 of the lock arm 16, and the front end portion of the arm main body portion 18 moves upward. The lock arm 16 is bent and deformed in the direction of being lifted up. At this time, the locking arm 62 is also flexibly deformed integrally with the lock arm 16. Until the two housings 10 and 80 are properly fitted, the protruding portion 85 enters the escape groove 73 of the locking portion 68 and is released, so that the lock portion 83 comes into contact with the locking portion 68. Avoided. Further, in the process of fitting, although not shown in detail, the urging member 40 is pressed against the mating housing 80 to be compressed, and the urging force is accumulated in the urging member 40.

その後、両ハウジング１０、８０が正規嵌合されると、図４に示すように、ロックアーム１６が弾性的に復帰するとともに、ロック部８３がロック孔１９に下方から嵌り込み、それと同時に、係止部６８がロック部８３により押し出されて、係止部６８と係止受部２２との係止が外れる。すると、付勢部材４０に蓄勢された付勢力が解放され、検知部材６０が検知位置へと自動的に移動させられる。また、ロック部８３がロック孔１９に進入することにより、ロック本体部８４がロック孔１９のロック面２１に当接可能に配置され、これによって両ハウジング１０、８０が嵌合状態に保持される。 Thereafter, when the two housings 10 and 80 are properly fitted, the lock arm 16 is elastically restored and the lock portion 83 is fitted into the lock hole 19 from below as shown in FIG. The stop portion 68 is pushed out by the lock portion 83, and the engagement between the engagement portion 68 and the engagement receiving portion 22 is released. Then, the biasing force stored in the biasing member 40 is released, and the detection member 60 is automatically moved to the detection position. Further, when the lock portion 83 enters the lock hole 19, the lock main body portion 84 is disposed so as to be able to contact the lock surface 21 of the lock hole 19, thereby holding both the housings 10 and 80 in a fitted state. .

検知部材６０が検知位置に至ると、操作アーム６６の移動規制部４７が移動規制受部２６の受溝２７に弾性的に嵌り込み（図５を参照）、移動規制部４７の規制面４４が移動規制受部２６の規制受面２８に当接可能に配置される（図６を参照）。したがって、検知部材６０がロックアーム１６に対して前方（待機位置側）へ移動する方向に押し込まれようとしても、規制面４４が規制受面２８に当接して、規制端部４５が受溝２７の前端角部３２に近づくように変位させられることで検知部材６０のそれ以上の前進が規制される。したがって、検知部材６０が不用意に待機位置に至ることはない。 When the detection member 60 reaches the detection position, the movement restricting portion 47 of the operation arm 66 is elastically fitted into the receiving groove 27 of the movement restricting receiving portion 26 (see FIG. 5), and the restricting surface 44 of the movement restricting portion 47 is moved. It arrange | positions so that contact | abutting to the control receiving surface 28 of the movement control receiving part 26 is possible (refer FIG. 6). Therefore, even if the detection member 60 is pushed in the direction of moving forward (standby position side) with respect to the lock arm 16, the regulation surface 44 comes into contact with the regulation receiving surface 28, and the regulation end 45 is received by the receiving groove 27 Further advancement of the detection member 60 is restricted by being displaced so as to approach the front end corner portion 32 of the front end. Therefore, the detection member 60 does not inadvertently reach the standby position.

一方、メンテナンス等の事情により、嵌合状態にある両ハウジング１０、８０を離脱させる際には、操作アーム６６の操作部４８に上方から押し込み力を付与する。すると、図７に示すように、操作アーム６６がシーソ状に揺動して、操作部４８が押し下げられるとともに、移動規制部４７が上方へ持ち上げられる。移動規制部４７が持ち上げられるに伴い、規制面４４が規制受面２８から解離し、移動規制部４７と移動規制受部２６との係止が外れる。 On the other hand, when the two housings 10 and 80 in the fitted state are detached due to maintenance or the like, a pushing force is applied to the operation portion 48 of the operation arm 66 from above. Then, as shown in FIG. 7, the operating arm 66 swings like a seesaw, the operating unit 48 is pushed down, and the movement restricting unit 47 is lifted upward. As the movement restricting portion 47 is lifted, the restricting surface 44 is disengaged from the restricting receiving surface 28, and the movement restricting portion 47 and the movement restricting receiving portion 26 are unlocked.

次いで、操作部４８に前方への押し込み力を付与すると、検知部材６０が前進して検知位置に至らしめられる。このとき、操作部４８の押し下げ状態が維持されていれば、ロックアーム１６のアーム本体部１８の後端部（移動規制受部２６）が操作部４８により押し下げられ、アーム本体部１８の前端部が持ち上げられて、ロック部８３がロック孔１９から抜け出るとともに、係止部６８がロック孔１９に嵌り込む。こうしてロックアーム１６とロック部８３とのロック状態が解除されると、両ハウジング１０、８０が付勢部材４０に付勢されて自動的に引き離される。 Next, when a forward pushing force is applied to the operation portion 48, the detection member 60 moves forward and reaches the detection position. At this time, if the depressed state of the operation portion 48 is maintained, the rear end portion (movement restriction receiving portion 26) of the arm main body portion 18 of the lock arm 16 is pushed down by the operation portion 48, and the front end portion of the arm main body portion 18 is reached. Is lifted so that the lock part 83 comes out of the lock hole 19 and the locking part 68 fits into the lock hole 19. When the lock state of the lock arm 16 and the lock portion 83 is released in this way, both the housings 10 and 80 are urged by the urging member 40 and automatically separated.

以上説明したように、本実施例によれば、検知部材６０が待機位置にあるときに、係止部６８の係止面部７５が係止受部２２の係止受面２４に対して係止アーム６２の係止解除方向（図示上方）で当接可能に対向して配置されるため、係止アーム６２が係止解除方向に不用意に撓み変形して、検知部材６０が検知位置に至る事態が回避される。その結果、検知部材６０による嵌合検知の信頼性を向上させることができる。とくに、本実施例の場合、検知部材６０が付勢部材４０によって検知位置に付勢された状態にあるため、係止部６８と係止受部２２との係止が外れると、検知部材６０が自動的に検知位置に移動させられるため、上記構成を採用することのメリットは大きい。 As described above, according to this embodiment, when the detection member 60 is in the standby position, the locking surface portion 75 of the locking portion 68 is locked to the locking receiving surface 24 of the locking receiving portion 22. Since the arms 62 are arranged so as to be able to come into contact with each other in the unlocking direction (upward in the drawing), the locking arm 62 is inadvertently bent and deformed in the unlocking direction, and the detection member 60 reaches the detection position. The situation is avoided. As a result, the reliability of the fitting detection by the detection member 60 can be improved. In particular, in the case of the present embodiment, since the detection member 60 is biased to the detection position by the biasing member 40, the detection member 60 is released when the locking portion 68 and the locking receiving portion 22 are unlocked. Is automatically moved to the detection position, so the merit of adopting the above configuration is great.

また、突出部７２が凹部２３に進入することにより、係止受部２２に対する係止部６８の幅方向への遊動が規制されるため、検知部材６０が待機位置にあるときに、係止部６８と係止受部２２との係止がより安定に維持される。 Further, since the protrusion 72 enters the recess 23, the loose movement in the width direction of the locking portion 68 with respect to the locking receiving portion 22 is restricted. Therefore, when the detection member 60 is in the standby position, the locking portion 68 and the latch receiving part 22 are more stably maintained.

また、本実施例によれば、検知部材６０が検知位置にあるときに、検知部材６０の操作アーム６６に前方（待機位置）への押し込み力が付与されても、移動規制部４７が移動規制受部２６と当接して検知部材６０のそれ以上の前進が規制されるため、検知部材６０が不用意に待機位置に至るのが防止される。この場合に、操作アーム６６が前後方向に延出してその延出途中に支点部４９を有し、支点部４９を中心としてシーソ状に揺動可能な形態になっているため、操作部４８への押圧操作を、ロックアーム１６に対する移動規制部４７の係止解除動作に円滑に連動させることができる。 Further, according to the present embodiment, when the detection member 60 is in the detection position, the movement restricting unit 47 restricts the movement even if a forward pushing force is applied to the operation arm 66 of the detection member 60. Since the further advancing of the detection member 60 is restricted in contact with the receiving portion 26, the detection member 60 is prevented from inadvertently reaching the standby position. In this case, the operation arm 66 extends in the front-rear direction, has a fulcrum part 49 in the middle of the extension, and can swing in a seesaw shape around the fulcrum part 49. Can be smoothly linked to the unlocking operation of the movement restricting portion 47 with respect to the lock arm 16.
