Description

本発明は、ロックアームを備えたコネクタに関する。 The present invention relates to a connector with a lock arm.

従来から、ロックアームを備えたコネクタが知られている。ロックアームは、一般に、相手側ハウジングに係合することで、コネクタと相手側コネクタとの嵌合状態を維持するようになっている(例えば、特許文献1~3を参照)。 Conventionally, a connector having a lock arm has been known. The lock arm is generally adapted to maintain a fitted state between the connector and the mating connector by engaging with the mating housing (see, for example, Patent Documents 1 to 3).

特開2001-250636号公報Japanese Unexamined Patent Publication No. 2001-250636 特開2015-103372号公報Japanese Unexamined Patent Publication No. 2015-103372 特開2016-131112号公報Japanese Unexamined Patent Publication No. 2016-131112

ところで、上記各文献に記載のコネクタ(以下、「従来のコネクタ」という。)では、ロックアームの係合部と相手側ハウジングの被係合部との係合を解除するためには、ロックアームに設けられた解除用の操作部をハウジングに近付ける向きに変位させる操作(以下、「解除操作」という。)を行うことになる。従来のコネクタでは、ハウジングに向けて突出する支持部がロックアームに設けられており、解除操作に伴い、支持部がハウジングの表面と接触する。そして、支持部が支点となってロックアームが湾曲するように変形することで、係合部が相手側ハウジングとの係合を解除する向きに変位するようになっている。 By the way, in the connector described in each of the above documents (hereinafter referred to as "conventional connector"), in order to disengage the engaged portion of the lock arm and the engaged portion of the mating housing, the lock arm is used. An operation (hereinafter referred to as "release operation") is performed to displace the release operation unit provided in the housing in a direction closer to the housing. In the conventional connector, a support portion protruding toward the housing is provided on the lock arm, and the support portion comes into contact with the surface of the housing during the release operation. Then, the support portion serves as a fulcrum and the lock arm is deformed so as to be curved, so that the engaging portion is displaced in the direction of disengaging the engagement with the mating housing.

ところが、支持部は突起状の形状を有するため、支持部が支点として機能する際、支持部の先端が押し付けられるハウジング表面に、大きな応力が生じ得る。そして、そのような応力に起因し、ハウジング表面に凹み等の変形が生じる虞がある。このような変形は、通常、解除操作に実質的な影響を及ぼさない。しかし、例えば、解除操作の際にロックアームに大きな外力が及んでハウジング表面に過大な変形が生じた場合、解除操作を行っても、ロックアームによる相手側ハウジングとの係合を適正に解除できないこととなる可能性がある。ロックアームによる係合を適正に解除し得る状態を維持する観点から、このようなハウジング表面の変形は、出来る限り抑制されることが好ましい。 However, since the support portion has a protruding shape, when the support portion functions as a fulcrum, a large stress may be generated on the housing surface to which the tip of the support portion is pressed. Then, due to such stress, there is a possibility that deformation such as a dent may occur on the housing surface. Such deformation usually has no substantial effect on the release operation. However, for example, when a large external force is applied to the lock arm during the release operation and excessive deformation occurs on the housing surface, the lock arm cannot properly release the engagement with the mating housing even if the release operation is performed. There is a possibility that it will be. From the viewpoint of maintaining a state in which the engagement by the lock arm can be properly released, it is preferable to suppress such deformation of the housing surface as much as possible.

本発明は、上述した事情に鑑みてなされたものであり、その目的は、ロックアームによる相手側ハウジングとの係合を適正に解除し得る状態を維持可能なコネクタを提供することにある。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a connector capable of maintaining a state in which the lock arm can be properly disengaged from the mating housing.

前述した目的を達成するために、本発明に係るコネクタは、下記[1]~[2]を特徴としている。

In order to achieve the above-mentioned object, the connector according to the present invention is characterized by the following [1] to [2].
[1]
A connector comprising a housing with a terminal accommodating chamber and a cantilever-shaped lock arm that can be engaged with the mating housing.
The lock arm is
The other party is arranged between a leaf spring portion having a fixed end connected to the housing and extending forward from the fixed end in the mating direction with the mating housing, and a free end and the fixed end of the leaf spring portion. An operation of connecting an engaging portion that can be engaged with the side housing, a pair of arm portions that extend from the leaf spring portion and extend rearward in the fitting direction, and the pair of arm portions so as to straddle the leaf spring portion. With a part,
When the operating portion is displaced toward the housing, the engaging portion moves in a direction of disengaging the mating housing with the contact point between the operating portion and the leaf spring portion as a fulcrum. The leaf spring portion is configured to be deformed.
Must be a connector.
[2]
In the connector described in [1] above,
The leaf spring portion is
It has a first portion extending from the fixed end so as to approach the operating portion, and a second portion extending forward from the first portion in the fitting direction.
The lock arm is
When the operating portion is displaced in a direction closer to the housing, the other part of the operating portion approaches the first portion with the contact point between a part of the operating portion and the second portion as the fulcrum. The engaging portion is configured to be displaced in a direction to disengage from the mating housing by further displacement to.
Must be a connector.

上記[1]の構成のコネクタによれば、ロックアームと相手側ハウジングとの係合を解除する際、ロックアームの操作部をハウジングに近付ける向きに変位させると、操作部と板ばね部とが接触する。そして、操作部と板ばね部との接触箇所を支点として、係合部が相手側ハウジングとの係合を解除する向きに動くように、前記板ばね部が変形する。換言すると、従来のコネクタのように、解除操作に伴ってロックアームの突出部がハウジング表面に押し付けられることがない。また、ロックアームは、内部に端子収容室のような空洞を設けるハウジングに比べ、通常、外力に対する耐性に優れるように設計することが容易である。よって、従来のコネクタに比べ、操作部に大きな外力が及んだ場合であっても、支点となる部分(即ち、操作部と板ばね部との接触箇所)の変形が生じ難い。したがって、本構成のコネクタは、ロックアームによる相手側ハウジングとの係合を適正に解除し得る状態を維持可能である。 According to the connector having the configuration of [1] above, when the engagement between the lock arm and the mating housing is disengaged, when the operation portion of the lock arm is displaced toward the housing, the operation portion and the leaf spring portion are displaced. Contact. Then, the leaf spring portion is deformed so that the engaging portion moves in the direction of disengaging the engagement with the mating housing with the contact point between the operation portion and the leaf spring portion as a fulcrum. In other words, unlike the conventional connector, the protrusion of the lock arm is not pressed against the surface of the housing during the release operation. Further, the lock arm is usually easy to be designed to have excellent resistance to an external force as compared with a housing having a cavity such as a terminal accommodating chamber inside. Therefore, as compared with the conventional connector, even when a large external force is applied to the operation portion, the portion serving as a fulcrum (that is, the contact point between the operation portion and the leaf spring portion) is less likely to be deformed. Therefore, the connector of this configuration can maintain a state in which the lock arm can be properly disengaged from the mating housing.

上記[2]の構成のコネクタによれば、板ばね部が、固定端から操作部に近付くように突出する第1部分と、第1部分から嵌合方向の前方に向けて延びる第2部分とを有する。即ち、固定端近傍において、板ばね部は、操作部に向けて延びた後に嵌合方向の前方に向けて延びる湾曲形状を有する。そして、解除操作を行う際、操作部の一部と第2部分との接触箇所を支点として、操作部の他の一部が第1部分に近付くように変位する。これにより、係合部が相手側ハウジングとの係合を解除する向きに動くように、板ばね部を容易に変位させられる。このように、本構成のコネクタは、上記[1]の構成のコネクタを簡単な構造にて実現できる。 According to the connector having the configuration of [2] above, the leaf spring portion has a first portion protruding from the fixed end so as to approach the operation portion, and a second portion extending forward from the first portion in the mating direction. Have. That is, in the vicinity of the fixed end, the leaf spring portion has a curved shape that extends toward the operation portion and then extends toward the front in the fitting direction. Then, when the release operation is performed, the other part of the operation unit is displaced so as to approach the first portion with the contact point between the part of the operation unit and the second portion as a fulcrum. As a result, the leaf spring portion can be easily displaced so that the engaging portion moves in a direction in which the engaging portion disengages from the mating housing. As described above, the connector having the present configuration can realize the connector having the configuration of the above [1] with a simple structure.

本発明によれば、ロックアームによる相手側ハウジングとの係合を適正に解除し得る状態を維持可能なコネクタを提供できる。 According to the present invention, it is possible to provide a connector capable of maintaining a state in which the lock arm can be appropriately disengaged from the mating housing.

以上、本発明について簡潔に説明した。更に、以下に説明される発明を実施するための形態(以下、「実施形態」という。)を添付の図面を参照して通読することにより、本発明の詳細は更に明確化されるであろう。 The present invention has been briefly described above. Further, the details of the present invention will be further clarified by reading through the embodiments described below (hereinafter referred to as "embodiments") with reference to the accompanying drawings. ..

It is a figure corresponding to FIG. 4A which shows the functioning state.

以下、図面を参照しながら、本発明の実施形態に係るコネクタ1について説明する。図1に示すコネクタ1のハウジング10は、相手側コネクタの相手側ハウジング(図示省略)と嵌合するようになっている。以下、説明の便宜上、図1に示すように、前後方向、上下方向、幅方向、前、後、上、下を定義する。前後方向、上下方向、及び幅方向は互いに直交している。前後方向は、コネクタ1と相手側コネクタとの嵌合方向と一致している。 Hereinafter, the connector 1 according to the embodiment of the present invention will be described with reference to the drawings. The housing 10 of the connector 1 shown in FIG. 1 is adapted to be fitted with the mating housing (not shown) of the mating connector. Hereinafter, for convenience of explanation, as shown in FIG. 1, the front-back direction, the up-down direction, the width direction, the front, the back, the top, and the bottom are defined. The front-back direction, the up-down direction, and the width direction are orthogonal to each other. The front-rear direction coincides with the mating direction between the connector 1 and the mating connector.

図1に示すように、樹脂製のハウジング10は、相手側ハウジングとの嵌合状態を維持するためのロックアーム20と、電線(図示省略)の端部に接続された端子(図示省略)を収容する端子収容部30と、端子収容部30の周囲を囲う筒形状を有するフード部40と、を備えている。なお、図示を省略しているが、ハウジング10は、防水用のパッキン、フード部40の前方からハウジング10に装着されるフロントホルダ、及び、端子収容室30に収容された端子の二重係止等のためのスペーサ等を備え得る。 As shown in FIG. 1, the resin housing 10 has a lock arm 20 for maintaining a fitted state with the mating housing, and a terminal (not shown) connected to an end of an electric wire (not shown). A terminal accommodating portion 30 for accommodating the terminal accommodating portion 30 and a hood portion 40 having a tubular shape surrounding the terminal accommodating portion 30 are provided. Although not shown, the housing 10 has a waterproof packing, a front holder mounted on the housing 10 from the front of the hood portion 40, and double locking of terminals housed in the terminal storage chamber 30. It may be provided with a spacer or the like for the like.

端子収容部30は、前後方向(即ち、相手側ハウジングとの嵌合方向)に沿って延在する略柱状の形状を有する。フード部40は、端子収容部30の周囲に、相手側ハウジングの筒状部(図示省略)が嵌合する環状隙間50を画成している。フード部40は、環状隙間50に嵌合する相手側ハウジングの筒状部の外周を覆うようになっている。 The terminal accommodating portion 30 has a substantially columnar shape extending along the front-rear direction (that is, the mating direction with the mating housing). The hood portion 40 defines an annular gap 50 around which the tubular portion (not shown) of the mating housing is fitted around the terminal accommodating portion 30. The hood portion 40 covers the outer periphery of the tubular portion of the mating housing that fits into the annular gap 50.

フード部40は、ロックアーム20を幅方向に挟むように幅方向に対向し且つ前後方向に延びる一対の保護壁41を有している。フード部40は、その側面(図1における右側の側面)に、スペーサ挿入口42を有している。スペーサ挿入口42は、スペーサ(図示省略)をハウジング10内の端子収容部30のスペーサ挿通部(図示省略)に取り付ける(挿入する)ための開口である。スペーサは、例えば、端子の半挿入状態を検知する機能、並びに、完全挿入状態にある端子の二重係止機能を有する。 The hood portion 40 has a pair of protective walls 41 that face each other in the width direction and extend in the front-rear direction so as to sandwich the lock arm 20 in the width direction. The hood portion 40 has a spacer insertion port 42 on its side surface (side surface on the right side in FIG. 1). The spacer insertion port 42 is an opening for attaching (inserting) the spacer (not shown) to the spacer insertion portion (not shown) of the terminal accommodating portion 30 in the housing 10. The spacer has, for example, a function of detecting a semi-inserted state of the terminal and a double locking function of the terminal in the fully inserted state.

ロックアーム20は、ハウジング10と相手側ハウジングとの嵌合が完了したとき、相手側ハウジングのロック突起(図示省略)と係合し、ハウジング10と相手側ハウジングとの嵌合状態を維持する機能を有する。 When the fitting of the housing 10 and the mating housing is completed, the lock arm 20 engages with the lock protrusion (not shown) of the mating housing and maintains the mating state between the housing 10 and the mating housing. Has.

図2~図4に示すように、ロックアーム20は、弾性変形可能な片持ち梁状の板ばね部21を備える。板ばね部21は、ハウジング10の端子収容部30の上面から上方に突出する第1部分22と、第1部分22の上端部から前方に向けて延びる略平板状の第2部分23と、を一体に有する(特に、図4参照)。換言すると、板ばね部21は、固定端近傍において、ハウジング10から離れる向きに延びた後に嵌合方向の前方に向けて延びる湾曲形状を有する。第1部分22の下端が板ばね部21の固定端に対応し、第2部分23の先端(前端)が板ばね部21の自由端に対応している。 As shown in FIGS. 2 to 4, the lock arm 20 includes a cantilever-shaped leaf spring portion 21 that is elastically deformable. The leaf spring portion 21 has a first portion 22 protruding upward from the upper surface of the terminal accommodating portion 30 of the housing 10, and a substantially flat plate-shaped second portion 23 extending forward from the upper end portion of the first portion 22. It has one body (particularly, see FIG. 4). In other words, the leaf spring portion 21 has a curved shape that extends away from the housing 10 and then extends forward in the fitting direction in the vicinity of the fixed end. The lower end of the first portion 22 corresponds to the fixed end of the leaf spring portion 21, and the tip (front end) of the second portion 23 corresponds to the free end of the leaf spring portion 21.

第2部分23の先端部は、相手側ハウジングのロック突起が係合する係合部24として機能する。係合部24には、相手側ハウジングのロック突起が係合する係合孔(貫通孔)25が形成されている。 The tip of the second portion 23 functions as an engaging portion 24 to which the locking projection of the mating housing engages. The engaging portion 24 is formed with an engaging hole (through hole) 25 with which the lock protrusion of the mating housing is engaged.

係合部24の幅方向両端部から、一対の連結アーム部26が、第2部分23の幅方向両端面より幅方向外側の位置にて、後方に一体で延出している。一対の連結アーム部26の後端部には、一対の連結アーム部26の後端部を繋ぐと共に前後方向に延びる略平板状の操作部27が一体で設けられている。 A pair of connecting arm portions 26 extend rearward from both ends of the engaging portion 24 in the width direction at positions outside the width directions of the second end portions 23 in the width direction. The rear end portions of the pair of connecting arm portions 26 are integrally provided with a substantially flat plate-shaped operating portion 27 that connects the rear end portions of the pair of connecting arm portions 26 and extends in the front-rear direction.

図4に示すように、操作部27の前端部27aは、板ばね部21の第2部分23の後端部23aの上方を幅方向にまたぐように、後端部23aとの間に上下方向の僅かな隙間を空けて位置している。操作部27の後端部27bは、板ばね部21の第1部分22より後方に位置している。このため、板ばね部21の第1部分22は、板ばね部21の固定端から操作部27に近付くように上方に突出している、ということもできる。 As shown in FIG. 4, the front end portion 27a of the operation portion 27 is vertically straddled between the rear end portion 23a and the rear end portion 23a of the second portion 23 of the leaf spring portion 21 so as to straddle the rear end portion 23a in the width direction. It is located with a slight gap between them. The rear end portion 27b of the operation portion 27 is located behind the first portion 22 of the leaf spring portion 21. Therefore, it can be said that the first portion 22 of the leaf spring portion 21 projects upward from the fixed end of the leaf spring portion 21 so as to approach the operation portion 27.

一対の連結アーム部26の前後方向における中央より若干後方寄りの位置の幅方向外側面には、幅方向外側に突出する一対のストッパ28が一体で設けられている。一対のストッパ28は、ハウジング10の一対の保護壁41の係合部(図示省略)と係合可能となっている。このため、ストッパ28は、操作部27に上方向(即ち、図4(b)の矢印Z2と反対の方向)の力が加わった場合、連結アーム部26が上方向に過度に変位して破損することを防止する機能を有する。 A pair of stoppers 28 projecting outward in the width direction are integrally provided on the outer surface in the width direction at a position slightly rearward from the center in the front-rear direction of the pair of connecting arm portions 26. The pair of stoppers 28 can be engaged with the engaging portion (not shown) of the pair of protective walls 41 of the housing 10. Therefore, when a force in the upward direction (that is, the direction opposite to the arrow Z2 in FIG. 4B) is applied to the operation portion 27, the stopper 28 is damaged due to excessive displacement of the connecting arm portion 26 in the upward direction. It has a function to prevent it from happening.

ロックアーム20は、ハウジング10と相手側ハウジングとの嵌合途中では、板ばね部21が上方向(即ち、図4(b)の矢印Z1方向)に撓むように弾性変形することにより、相手側ハウジングのロック突起を係合部24の下に潜り込ませる。そして、ハウジング10と相手側ハウジングとの嵌合が完了するとき、板ばね部21の復元力によって係合部24の位置が弾性変形前の初期位置に戻る。これにより、係合孔25に相手側ハウジングのロック突起が係合し、ハウジング10と相手側ハウジングの嵌合状態が維持される。 The lock arm 20 is elastically deformed so that the leaf spring portion 21 bends upward (that is, in the direction of arrow Z1 in FIG. 4B) during the fitting between the housing 10 and the mating housing, so that the mating housing The lock protrusion of the above is slipped under the engaging portion 24. Then, when the fitting between the housing 10 and the mating housing is completed, the position of the engaging portion 24 returns to the initial position before elastic deformation due to the restoring force of the leaf spring portion 21. As a result, the lock protrusion of the mating housing engages with the engaging hole 25, and the fitted state of the housing 10 and the mating housing is maintained.

一方、図4(b)に示すように、操作部27の後端部27bが下方向(図4(b)のZ2方向)に押し下げられると、操作部27の前端部27aの下面(平面)が、板ばね部21の第2部分23の後端部23aの上面(平面)と対面接触する(図4(b)のB部参照)。更に後端部27bを押し下げると、この接触箇所を支点として、操作部27の後端部27bが板ばね部21の第1部分22に近付くように変位する。この結果、板ばね部21が、図4(b)において時計回りに湾曲するように変形する。これにより、係合部24が上向き(即ち、図4(b)の矢印Z1方向。相手側ハウジングとの係合を解除する向き)に変位する。これにより、係合部24とロック突起との係合が解除され、ハウジング10と相手側ハウジングとが分離可能な状態となる。 On the other hand, as shown in FIG. 4B, when the rear end portion 27b of the operation portion 27 is pushed down in the downward direction (Z2 direction in FIG. 4B), the lower surface (planar surface) of the front end portion 27a of the operation portion 27. Is in face-to-face contact with the upper surface (plane surface) of the rear end portion 23a of the second portion 23 of the leaf spring portion 21 (see the portion B in FIG. 4B). When the rear end portion 27b is further pushed down, the rear end portion 27b of the operation portion 27 is displaced so as to approach the first portion 22 of the leaf spring portion 21 with this contact point as a fulcrum. As a result, the leaf spring portion 21 is deformed so as to be curved clockwise in FIG. 4 (b). As a result, the engaging portion 24 is displaced upward (that is, in the direction of arrow Z1 in FIG. 4B, which is the direction in which the engagement with the mating housing is disengaged). As a result, the engagement between the engaging portion 24 and the lock protrusion is released, and the housing 10 and the mating housing are in a separable state.

以上、本発明の実施形態に係るコネクタ1によれば、ロックアーム20の係合部24と相手側ハウジングとの係合を解除する際、ロックアーム20の操作部27をハウジング10に近付ける向き(即ち、下向き。図4(b)のZ2方向)に変位させると、操作部27と板ばね部21との接触箇所(図4(b)のB部参照)を支点として、係合部24が相手側ハウジングとの係合を解除する向き(即ち、上向き。図4(b)のZ1方向)に変位する。これにより、従来のコネクタに比べ、操作部27に大きな外力が及んだ場合であっても、ハウジング10の端子収容部30の表面の変形等が生じ難い。 As described above, according to the connector 1 according to the embodiment of the present invention, when the engaging portion 24 of the lock arm 20 and the mating housing are disengaged, the operation portion 27 of the lock arm 20 is brought closer to the housing 10 (the direction in which the operating portion 27 of the lock arm 20 is brought closer to the housing 10 ( That is, when displaced downward (in the Z2 direction in FIG. 4 (b)), the engaging portion 24 becomes a fulcrum with the contact point between the operation portion 27 and the leaf spring portion 21 (see the portion B in FIG. 4 (b)) as a fulcrum. It is displaced in the direction of disengagement from the mating housing (that is, upward, in the Z1 direction in FIG. 4B). As a result, compared to the conventional connector, even when a large external force is applied to the operation portion 27, the surface of the terminal accommodating portion 30 of the housing 10 is less likely to be deformed.

また、ロックアーム20は、内部に端子収容室のような空洞を設けるハウジング10に比べ、通常、外力に対する耐性に優れるように設計することが容易である。例えば、図4(a)及び図4(b)において、接触箇所Bの周辺における板ばね部21の上下方向における厚さを、係合解除時の外力に十分に耐え得る厚さに設計することが考えられる。 Further, the lock arm 20 is usually easy to be designed to have excellent resistance to an external force as compared with a housing 10 having a cavity such as a terminal accommodating chamber inside. For example, in FIGS. 4A and 4B, the thickness of the leaf spring portion 21 around the contact point B in the vertical direction is designed to be sufficiently able to withstand the external force at the time of disengagement. Can be considered.

よって、本構成のコネクタ1は、ロックアーム20による相手側ハウジングとの係合を、必要に応じて適正に解除し得る。更に、従来のコネクタに比べ、このような状態を適正に維持可能である。 Therefore, the connector 1 having the present configuration can appropriately disengage the engagement of the lock arm 20 with the housing on the other side, if necessary. Further, as compared with the conventional connector, such a state can be properly maintained.
