Description

本発明は、コネクタ嵌合方向およびコネクタ嵌合直交方向のガタツキを抑える構成を備えたコネクタに関し、特に、部品点数を削減し、低コスト化、軽量化を可能とする改良技術に関する。 The present invention relates to a connector having a configuration that suppresses rattling in a connector fitting direction and a connector fitting orthogonal direction, and more particularly, to an improved technique that can reduce the number of parts and reduce cost and weight.

車両に使用されるコネクタは、走行時等の振動によって雌雄端子の接点部が磨耗して電気的接続不良の発生する虞がある。そこで、嵌合状態にある雌雄コネクタハウジングの相互のガタツキを抑制して、擦れ合いによる雌雄端子の接点部の磨耗を低減するように耐振機能を付与したコネクタが知られている（例えば、特許文献１参照）。 In connectors used in vehicles, there is a concern that contact portions of male and female terminals may be worn due to vibrations during traveling or the like, resulting in poor electrical connection. Therefore, there is known a connector provided with a vibration proof function so as to suppress the backlash of the male and female connector housings in the fitted state and reduce wear of the contact portions of the male and female terminals due to friction (for example, Patent Documents). 1).

図１３は従来の耐振機能を有したコネクタの断面図である。
従来のコネクタ５００は、インナハウジング５０１の外周面上に形成され且つ傾斜面５０３ａを有するガタツキ規制部５０３と、インナハウジング５０１と雌型コネクタハウジング５０５との嵌合時にインナハウジング５０１を受け入れるために雌型コネクタハウジング５０５内に形成されたコネクタ嵌合室５０７と、コネクタ嵌合室５０７の内周面に形成され傾斜面５０３ａと面接触可能な規制面５０９と、インナハウジング５０１とアウタハウジング５１１との間に配置されインナハウジング５０１と雌型コネクタハウジング５０５との完全嵌合時に傾斜面５０３ａが規制面５０９と面接触し且つ当該規制面５０９を押圧するようにインナハウジング５０１を雌型コネクタハウジング５０５への嵌合方向に弾性反発力で付勢する金属製のコイルバネ５１３と、を備えている。なお、図１３中、５１５は雌型コネクタ、５１７は雄型コネクタ、５１９は雌端子、５２１は雄端子、５２３は防水パッキンを示す。 FIG. 13 is a cross-sectional view of a conventional connector having a vibration resistance function.
The conventional connector 500 is formed on the outer peripheral surface of the inner housing 501 and has a female surface for receiving the inner housing 501 when the inner housing 501 and the female connector housing 505 are fitted to the backlash regulating portion 503 having an inclined surface 503a. A connector fitting chamber 507 formed in the mold connector housing 505, a regulating surface 509 formed on the inner peripheral surface of the connector fitting chamber 507 and in contact with the inclined surface 503a, an inner housing 501 and an outer housing 511 The inner housing 501 is moved to the female connector housing 505 so that the inclined surface 503a is in surface contact with and presses the restriction surface 509 when the inner housing 501 and the female connector housing 505 are completely fitted. Made of metal that is urged by elastic repulsive force in the mating direction And Irubane 513, is equipped with a. In FIG. 13, 515 is a female connector, 517 is a male connector, 519 is a female terminal, 521 is a male terminal, and 523 is a waterproof packing.

このコネクタ５００では、雄型コネクタ５１７をインナハウジング５０１とアウタハウジング５１１に分割し、インナハウジング５０１とアウタハウジング５１１の間にコイルバネ５１３を設置し、コイルバネ５１３の反力でインナハウジング５０１の傾斜面５０３ａを雌型コネクタ５１５の規制面５０９に押し付けることにより、常時荷重をかけ、嵌合状態の雄型コネクタ５１７と雌型コネクタ５１５との間に生じるコネクタ嵌合方向及びコネクタ嵌合直交方向のガタツキを防止し、雌雄両端子５１９，５２１の電気接触部の摩耗等を防止している。 In this connector 500, the male connector 517 is divided into an inner housing 501 and an outer housing 511, a coil spring 513 is installed between the inner housing 501 and the outer housing 511, and the inclined surface 503a of the inner housing 501 is caused by the reaction force of the coil spring 513. Is pressed against the restricting surface 509 of the female connector 515 so that a load is always applied, and rattling in the connector fitting direction and the connector fitting orthogonal direction generated between the male connector 517 and the female connector 515 in the fitted state is prevented. This prevents the electrical contact portions of the male and female terminals 519 and 521 from being worn.

しかしながら、上記した従来のコネクタ５００は、雌雄両端子５１９，５２１の摩耗等防止を目的に、雄型コネクタ５１７をインナハウジング５０１とアウタハウジング５１１に分割し、これらハウジング間にコイルバネ５１３を設置し、その反力でインナハウジング５０１の傾斜面５０３ａを雌型コネクタ５１５の規制面５０９に押し付け、常時荷重をかけ、コネクタ嵌合方向及びコネクタ嵌合直交方向のガタツキを防止する。このため、雄型コネクタハウジングを２つに分割しなければならないとともに、その間に複数のコイルバネ５１３が必要となり、耐振機能を有しない通常コネクタに比べ、部品点数が大幅に増大し、コストが増大し、重量が増した。 However, in the conventional connector 500 described above, the male connector 517 is divided into an inner housing 501 and an outer housing 511 for the purpose of preventing wear and the like of both male and female terminals 519 and 521, and a coil spring 513 is installed between these housings. With the reaction force, the inclined surface 503a of the inner housing 501 is pressed against the regulating surface 509 of the female connector 515, and a load is always applied to prevent rattling in the connector fitting direction and the connector fitting orthogonal direction. For this reason, the male connector housing must be divided into two parts, and a plurality of coil springs 513 are required between them, and the number of parts is greatly increased and the cost is increased as compared with a normal connector having no vibration resistance function. The weight increased.

本発明は上記状況に鑑みてなされたもので、簡素な構造で両コネクタハウジングの相対移動を規制できるコネクタを提供し、もって、耐振機能を付与するコネクタの部品点数を削減し、低コスト化、軽量化を図ることを目的とする。 The present invention has been made in view of the above situation, and provides a connector that can regulate the relative movement of both connector housings with a simple structure, thereby reducing the number of parts of the connector that imparts a vibration proof function, reducing costs, The purpose is to reduce weight.

本発明に係る上記目的は、下記構成により達成される。
（１）外面にフード部を備えた雌コネクタハウジングと、前記フード部と該フード部の内方側に位置する端子収容室との間に挿入される雄コネクタハウジングとを備え、両コネクタハウジングが嵌合することにより各コネクタハウジングに収容された雌雄端子が互いに接続するコネクタにおいて、
前記フード部の内壁面と該内壁面に対向する前記雄コネクタハウジングの外壁面とのそれぞれの部位に半球状の突起又は該突起を係止可能にする半球面状の凹部が設けられ、前記両コネクタハウジングの嵌合時、前記突起と前記凹部とが圧接状態で係合することを特徴とするコネクタ。 The above object of the present invention is achieved by the following configuration.
(1) A female connector housing having a hood portion on the outer surface, and a male connector housing inserted between the hood portion and a terminal accommodating chamber located on the inner side of the hood portion, In the connector where the male and female terminals accommodated in each connector housing are connected to each other by fitting,
A hemispherical protrusion or a hemispherical recess that allows the protrusion to be locked is provided on each of the inner wall surface of the hood portion and the outer wall surface of the male connector housing that faces the inner wall surface. The connector, wherein the protrusion and the recess are engaged in a pressure contact state when the connector housing is fitted.

このコネクタによれば、雌コネクタハウジングと雄コネクタハウジングが嵌合を開始すると、雄コネクタハウジングが雌コネクタハウジングのフード部に入り、フード部の内壁面から突出する突起が雄コネクタハウジングの先端に当たる。さらに嵌合が進むと、フード部が撓んで持ち上がり、突起の先端が雄コネクタハウジングの外壁面上を進む。突起が凹部に達すると、突起はフード部の撓みによる反発力で凹部に嵌る。突起は、凹部に入り込んだ状態に保たれ、これにより、両コネクタハウジングのコネクタ嵌合方向及びコネクタ嵌合直交方向の相対移動が規制され、ガタが生じ難くなる。なお、ここでの「撓み」とは、弾性変形及び塑性変形を含む広義の変形を言う。 According to this connector, when the female connector housing and the male connector housing start to be fitted, the male connector housing enters the hood portion of the female connector housing, and the protrusion protruding from the inner wall surface of the hood portion hits the tip of the male connector housing. As the fitting further proceeds, the hood portion is bent and lifted, and the tip of the protrusion advances on the outer wall surface of the male connector housing. When the projection reaches the recess, the projection fits into the recess due to a repulsive force due to the bending of the hood portion. The protrusion is kept in the recessed portion, whereby the relative movement of both connector housings in the connector fitting direction and the connector fitting orthogonal direction is restricted, and rattling is less likely to occur. Here, “deflection” refers to deformation in a broad sense including elastic deformation and plastic deformation.

（２）（１）のコネクタであって、
前記突起及び前記凹部が略同径に形成されていることを特徴とするコネクタ。 (2) The connector according to (1),
The connector, wherein the protrusion and the recess are formed to have substantially the same diameter.

このコネクタによれば、突起及び凹部が略同径となることで、隙間のない嵌め合いとなり、突起が凹部に入り込んだ状態でのコネクタ嵌合方向及びコネクタ嵌合直交方向の相対移動の規制作用が高まる。 According to this connector, since the protrusion and the recess have substantially the same diameter, the fitting is performed without a gap, and the relative movement in the connector fitting direction and the connector fitting orthogonal direction in a state where the protrusion enters the recess is restricted. Will increase.

（３）（１）又は（２）のコネクタであって、
前記凹部が前記突起より大径に形成されるとともに、両者の球面中心と接触点を通る直線がコネクタ嵌合方向に直交することを特徴とするコネクタ。 (3) The connector according to (1) or (2),
The connector is characterized in that the recess is formed with a larger diameter than the protrusion, and a straight line passing through the center of the spherical surface and the contact point is orthogonal to the connector fitting direction.

このコネクタによれば、大径の凹部の内に小径の突起が入って突起の先端が凹部の最深部に当接する。両者の球面中心と接触点を通る直線がコネクタ嵌合方向に直交することで、両コネクタハウジングの嵌合方向に直交する方向の相対移動が規制される。また、突起が凹部の最深部に接しているので、コネクタ嵌合方向の相対移動（球状凹面を這い上がろうとする移動）にも突起は凹部の球面から反力を受けることとなり、この反力がコネクタ嵌合方向の相対移動の規制力として働く。 According to this connector, the small-diameter projection enters the large-diameter recess, and the tip of the projection contacts the deepest portion of the recess. Since the straight line passing through both spherical centers and the contact point is perpendicular to the connector fitting direction, relative movement in the direction perpendicular to the fitting direction of both connector housings is restricted. In addition, since the protrusion is in contact with the deepest part of the recess, the protrusion receives a reaction force from the spherical surface of the recess even in the relative movement in the connector fitting direction (a movement to scoop up the spherical concave surface). Acts as a regulating force for relative movement in the connector fitting direction.

（４）（１）又は（２）のコネクタであって、
前記凹部の球面中心を通りコネクタ嵌合方向に直交する直線を挟んでハウジング相互当接部の反対側に接触点が位置することを特徴とするコネクタ。 (4) The connector according to (1) or (2),
A contact point is located on the opposite side of the housing mutual contact portion across a straight line passing through the spherical center of the recess and orthogonal to the connector fitting direction.

このコネクタによれば、両コネクタハウジングの嵌合が完了すると、ハウジング相互当接部（例えば雌コネクタハウジングの端子収容室の先端面と雄コネクタハウジングの受入部座面との当接部）が当接状態となり、それ以上の嵌合方向の相対移動が阻止される。この状態で、凹部の球面中心を通り嵌合方向に直交する直線を挟んでハウジング相互当接部の反対側に接触点が位置することで、凹部と突起とには、突起の接触点と凹部の最深部とを接近させようとする力（求心力）が相互に働く。この力は、雌コネクタハウジングでは、端子収容室の先端面を受入部座面に押圧する方向の力となり、雄コネクタハウジングでは、受入部座面を端子収容室の先端面に押圧する方向の力となる。つまり、ハウジング相互当接部で当接面同士をより強く当接させる力が作用する。これにより、嵌合解除方向への移動が生じ難くなる。同時に、凹部の球面が突起から押圧されていることにより、両コネクタハウジングの嵌合方向に直交する方向の相対移動も規制され、ガタが生じ難くなる。 According to this connector, when the fitting of both the connector housings is completed, the housing mutual contact portion (for example, the contact portion between the front end surface of the terminal housing chamber of the female connector housing and the seat surface of the receiving portion of the male connector housing) is contacted. The contact state is established, and further relative movement in the fitting direction is prevented. In this state, the contact point is located on the opposite side of the housing mutual contact portion across the straight line passing through the spherical center of the recess and orthogonal to the fitting direction. Forces (centripetal force) that try to approach the deepest part of each other work mutually. In the female connector housing, this force is a force in a direction in which the front end surface of the terminal accommodating chamber is pressed against the receiving portion seat surface, and in a male connector housing, a force in a direction in which the receiving portion seat surface is pressed against the front end surface of the terminal accommodating chamber. It becomes. That is, the force which makes contact | abutting surfaces contact | abut more strongly in a housing mutual contact part acts. Thereby, the movement to a fitting cancellation | release direction becomes difficult to produce. At the same time, since the spherical surface of the recess is pressed from the protrusion, the relative movement in the direction orthogonal to the fitting direction of both connector housings is also restricted, and rattling is less likely to occur.

（５）（１）〜（４）のいずれか１つのコネクタであって、
前記フード部が弾性力を有していることを特徴とするコネクタ。 (5) The connector according to any one of (1) to (4),
The connector, wherein the hood portion has an elastic force.

このコネクタによれば、フード部が弾性力を有していることで、嵌合時に、フード部が弾性変形して持ち上がり、突起が凹部に達すると、突起はフード部の弾性復元力で凹部に嵌る。両コネクタハウジングが再び嵌合解除されれば、フード部の変形は解消され、元の形状に戻る。フード部が弾性力を有することで、両コネクタハウジングの挿入性への影響も少なくできる。 According to this connector, since the hood portion has an elastic force, the hood portion is elastically deformed and lifted when fitted, and when the projection reaches the recess, the projection is brought into the recess by the elastic restoring force of the hood portion. fit. If both connector housings are released from the mating again, the deformation of the hood portion is eliminated and the original shape is restored. Since the hood portion has an elastic force, the influence on the insertability of both connector housings can be reduced.

（６）（１）〜（５）のいずれか１つのコネクタであって、
前記突起が前記フード部に形成され、前記凹部が前記雄コネクタハウジングに形成されていることを特徴とするコネクタ。 (6) The connector according to any one of (1) to (5),
The connector, wherein the protrusion is formed in the hood portion, and the concave portion is formed in the male connector housing.

このコネクタによれば、フード部の内壁面から突起が突出し、この突起を形成する際の金型が凹型となり、成形が容易となる。逆に、フード部の内壁面に凹部を形成した場合には、金型が凸型となり、凸型が引っ掛かり離型が困難となる。 According to this connector, the protrusion protrudes from the inner wall surface of the hood portion, and the mold for forming the protrusion becomes a concave shape, which facilitates molding. On the contrary, when the concave portion is formed on the inner wall surface of the hood portion, the mold becomes a convex shape, and the convex shape is caught and it becomes difficult to release the mold.

（７）（１）〜（６）のいずれか１つのコネクタであって、
前記突起及び前記凹部がコネクタハウジングの両側面のそれぞれに少なくとも２組形成されていることを特徴とするコネクタ。 (7) The connector according to any one of (1) to (6),
2. The connector according to claim 1, wherein at least two sets of the protrusions and the recesses are formed on both side surfaces of the connector housing.

このコネクタによれば、それぞれの側面に、突起及び凹部が２組設けられていることで、２箇所で動きを抑えられ、より大きな荷重（振動荷重）に耐えることが可能となる。突起及び凹部が１組の場合には、嵌り状態における突起及び凹部の球面中心を通りコネクタ嵌合方向に直交する直線を軸に、両コネクタハウジングが相対回転可能となるが、２組とすることでこの相対回転が規制され、よりガタツキが生じ難くなる。 According to this connector, since two sets of protrusions and recesses are provided on each side surface, movement can be suppressed at two locations, and a larger load (vibration load) can be withstood. When there is one set of protrusions and recesses, both connector housings can rotate relative to each other about a straight line that passes through the center of the spherical surface of the protrusions and recesses in the fitted state and is orthogonal to the connector fitting direction. Thus, this relative rotation is restricted, and it becomes more difficult for the rattling to occur.

本発明に係るコネクタによれば、フード部の内壁面と雄コネクタハウジングの外壁面とに、半球状の突起又はこの突起を係止可能にする半球面状の凹部を設け、両コネクタハウジングの嵌合時、突起と凹部とを圧接状態で係合するので、簡素な構造で両コネクタハウジングの相対移動を規制することができるようになり、特に耐振機能を付与するコネクタの部品点数を削減し、低コスト化、軽量化を達成できる。 According to the connector of the present invention, the inner wall surface of the hood portion and the outer wall surface of the male connector housing are provided with a hemispherical protrusion or a hemispherical concave portion that can lock the protrusion. At the time, the protrusion and the recess are engaged in a pressure contact state, so that the relative movement of both connector housings can be restricted with a simple structure, and in particular, the number of parts of the connector that provides a vibration proof function is reduced. Cost reduction and weight reduction can be achieved.

以下、本発明の実施の形態を図面を参照して説明する。
図１は本発明に係るコネクタの雌コネクタハウジングの斜視図である。
本実施の形態に係るコネクタ１００（図７参照）は、形状の合った部分を相互に嵌め合わせて（嵌合して）一体となる（結合する）雌コネクタ１１と、雄コネクタ１３（図２参照）とからなる。雌コネクタ１１は雌コネクタハウジング１５を有し、雄コネクタ１３は雄コネクタハウジング１７（図２参照）を有する。雌コネクタハウジング１５、雄コネクタハウジング１７は、それぞれ合成樹脂材料を射出成形することなどにより形成されている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a female connector housing of a connector according to the present invention.
The connector 100 (see FIG. 7) according to the present embodiment includes a female connector 11 and a male connector 13 (see FIG. 2) that fit together (combine) by fitting (fitting) the matching portions together. Reference). The female connector 11 has a female connector housing 15, and the male connector 13 has a male connector housing 17 (see FIG. 2). The female connector housing 15 and the male connector housing 17 are each formed by injection molding a synthetic resin material.

雌コネクタハウジング１５は、外面に偏平筒状のフード部２１を備える。フード部２１は、コネクタ嵌合方向（正確にはコネクタ嵌合・離脱方向）ａの結合側に、結合開口２３を有する。フード部２１の内方側には略相似形の端子収容室２５がコネクタ嵌合方向ａの同軸線上に設けられている。端子収容室２５には複数のキャビティ２７（図５参照）が並設され、キャビティ２７は端子収容室２５の先端面２９で雄端子進入口２７ａ（図５参照）となって開口する。端子収容室２５とフード部２１の間には、雄コネクタハウジング１７の結合先端部３５（図２参照）と嵌合する環状空間（受入部）３１が形成される。 The female connector housing 15 includes a flat cylindrical hood portion 21 on the outer surface. The hood portion 21 has a coupling opening 23 on the coupling side in the connector fitting direction (more precisely, the connector fitting / detaching direction) a. A generally similar terminal accommodating chamber 25 is provided on the coaxial line in the connector fitting direction a on the inner side of the hood portion 21. A plurality of cavities 27 (see FIG. 5) are arranged side by side in the terminal accommodating chamber 25, and the cavities 27 open on the front end surface 29 of the terminal accommodating chamber 25 as male terminal entrances 27a (see FIG. 5). Between the terminal accommodating chamber 25 and the hood portion 21, an annular space (receiving portion) 31 that fits with the coupling tip portion 35 (see FIG. 2) of the male connector housing 17 is formed.

雌コネクタハウジング１５は、不図示の枢軸により回動自在に支持された回転ロックレバー３３を備える。回転ロックレバー３３は、雌コネクタハウジング１５と雄コネクタハウジング１７とが少ない力で容易に嵌合及び離脱されるように、両コネクタハウジング１５，１７の嵌脱動作を支援し、さらにはそれらの嵌合状態が維持されるようにロックを可能とする。 The female connector housing 15 includes a rotation lock lever 33 that is rotatably supported by a pivot (not shown). The rotation lock lever 33 supports the fitting / removing operation of the connector housings 15 and 17 so that the female connector housing 15 and the male connector housing 17 can be easily fitted and detached with a small force. Locking is enabled so that the combined state is maintained.

図２は本発明に係るコネクタの雄コネクタハウジングの斜視図である。
雄コネクタハウジング１７は、偏平筒状の外形状で形成され、コネクタ嵌合方向ａの結合側が結合先端部３５となって受入部３１と嵌合する。結合先端部３５の上面には回転ロックレバー３３の嵌脱動作支援時に係合する凸部３７，３７と、ロック時に係合するロック部３９とが突設される。結合先端部３５は、端子収容室２５を受け入れる端子収容室受入開口部４１を有し、この端子収容室受入開口部４１の内部には雌コネクタハウジング１５の各キャビティ２７に対応する複数の雄端子４３（図７参照）を突出させている。 FIG. 2 is a perspective view of the male connector housing of the connector according to the present invention.
The male connector housing 17 is formed in a flat cylindrical outer shape, and the coupling side in the connector fitting direction “a” serves as a coupling tip portion 35 and is fitted to the receiving portion 31. On the upper surface of the coupling tip portion 35, projecting portions 37, 37 that are engaged when assisting the fitting / removing operation of the rotary lock lever 33, and a lock portion 39 that is engaged when locking are provided. The coupling tip 35 has a terminal accommodating chamber receiving opening 41 for receiving the terminal accommodating chamber 25, and a plurality of male terminals corresponding to the cavities 27 of the female connector housing 15 are provided inside the terminal accommodating chamber receiving opening 41. 43 (see FIG. 7) is projected.

雌コネクタハウジング１５の各キャビティ２７には雌端子４５（図５参照）が収容され、雌端子４５は雄端子進入口２７ａから進入する雄端子４３を受け入れて接触し電気的に接続する。すなわち、コネクタ１００は、両コネクタハウジング１５，１７が嵌合することにより、各コネクタハウジング１５，１７に収容された雌雄端子４５，４３を互いに接続する。 Each cavity 27 of the female connector housing 15 accommodates a female terminal 45 (see FIG. 5). The female terminal 45 receives and contacts and electrically connects the male terminal 43 entering from the male terminal entrance 27a. That is, the connector 100 connects the male and female terminals 45 and 43 accommodated in the connector housings 15 and 17 by fitting both the connector housings 15 and 17 together.

図３は図１に示した雌コネクタハウジングの正面図、図４は図３のＡ−Ａ断面図、図５は図３のＢ−Ｂ断面図である。
コネクタ１００は、フード部２１の内壁面４７と、この内壁面４７（図４参照）に対向する雄コネクタハウジング１７の外壁面４９（図２参照）とのそれぞれの部位に、半球状の突起５１又はこの突起５１を係止可能にする半球面状の凹部５３を備えている。これら突起５１と凹部５３は、両コネクタハウジング１５，１７の嵌合時、圧接状態で係合する。突起５１は、両コネクタハウジング１５，１７が嵌合されたとき、必ず凹部５３の範囲に入るよう寸法設定されている。 3 is a front view of the female connector housing shown in FIG. 1, FIG. 4 is a sectional view taken along line AA in FIG. 3, and FIG. 5 is a sectional view taken along line BB in FIG.
The connector 100 has hemispherical protrusions 51 at respective portions of the inner wall surface 47 of the hood portion 21 and the outer wall surface 49 (see FIG. 2) of the male connector housing 17 facing the inner wall surface 47 (see FIG. 4). Alternatively, a hemispherical concave portion 53 that can lock the protrusion 51 is provided. The protrusions 51 and the recesses 53 are engaged in a pressure contact state when the connector housings 15 and 17 are fitted. The protrusion 51 is dimensioned so that it always enters the range of the recess 53 when the connector housings 15 and 17 are fitted.

本実施の形態では、突起５１がフード部２１の内壁面４７に形成され、凹部５３が雄コネクタハウジング１７の外壁面４９に形成される。突起５１がフード部２１に形成されることで、フード部２１の内壁面４７から突起５１が突出し、この突起５１を形成する際の金型が凹型となり、成形が容易となる。逆に、フード部２１の内壁面４７に凹部５３を形成した場合には、金型が凸型となり、凸型が引っ掛かり離型が困難となる。また、突起５１を雄コネクタハウジング１７の外壁面４９に設ければ、雄コネクタハウジング１７の外形寸法が大きくなるが、本実施の形態のように外壁面４９に凹部５３を設ければこのような大型化が避けられる。また、フード部２１内に突起５１を設ければ、外壁面４９に設ける構成に比べ、突起５１の傷つきを防止して保護に有効となる。 In the present embodiment, the protrusion 51 is formed on the inner wall surface 47 of the hood portion 21, and the recess 53 is formed on the outer wall surface 49 of the male connector housing 17. By forming the protrusion 51 on the hood portion 21, the protrusion 51 protrudes from the inner wall surface 47 of the hood portion 21, and the mold for forming the protrusion 51 becomes a concave shape, which facilitates molding. On the contrary, when the recessed part 53 is formed in the inner wall surface 47 of the food | hood part 21, a metal mold | die will become a convex type and a convex type will be hooked and mold release will become difficult. Further, if the protrusion 51 is provided on the outer wall surface 49 of the male connector housing 17, the outer dimension of the male connector housing 17 is increased. However, if the recess 53 is provided on the outer wall surface 49 as in the present embodiment, Larger size can be avoided. Further, if the protrusion 51 is provided in the hood portion 21, the protrusion 51 is prevented from being damaged and effective in protection as compared with the structure provided on the outer wall surface 49.

なお、本実施の形態では、突起５１をフード部２１に形成し、凹部５３を雄コネクタハウジング１７の外壁面４９に形成することで、上記した成形容易性等の利点が得られるが、本発明に係るコネクタは、これに限定されるものではない。すなわち、フード部２１の内壁面４７に凹部５３を形成し、雄コネクタハウジング１７の外壁面４９に突起５１を形成しても後述する発明の効果は同様に奏する。 In the present embodiment, the protrusion 51 is formed on the hood portion 21 and the recess 53 is formed on the outer wall surface 49 of the male connector housing 17 to obtain the advantages such as the ease of molding described above. However, the connector according to the present invention is not limited to this. That is, even if the concave portion 53 is formed on the inner wall surface 47 of the hood portion 21 and the protrusion 51 is formed on the outer wall surface 49 of the male connector housing 17, the effects of the invention described later are similarly obtained.

フード部２１は、突起５１の設けられている側壁部が他の壁部よりも厚みの薄い薄肉部５５（図５参照）となっている。薄肉部５５は、弾性力を有している。フード部２１は、薄肉部５５が弾性力を有していることにより、嵌合時に、薄肉部５５が弾性変形して持ち上がり、突起５１が凹部５３に達すると、突起５１は薄肉部５５の弾性復元力で凹部５３に嵌る。両コネクタハウジング１５，１７が再び嵌合解除されれば、薄肉部５５の変形は解消され、元の形状に戻る。薄肉部５５が弾性力を有することで、両コネクタハウジング１５，１７の挿入性への影響も少なくなっている。つまり、挿入性を低下させることなく、ガタツキを抑止している。 The hood part 21 is a thin part 55 (see FIG. 5) in which the side wall part on which the protrusion 51 is provided is thinner than the other wall parts. The thin portion 55 has an elastic force. In the hood portion 21, since the thin portion 55 has an elastic force, the thin portion 55 is elastically deformed and lifted when fitted, and when the protrusion 51 reaches the recess 53, the protrusion 51 becomes elastic of the thin portion 55. Fits into the recess 53 with a restoring force. When the connector housings 15 and 17 are released from each other again, the deformation of the thin portion 55 is eliminated and the original shape is restored. Since the thin portion 55 has an elastic force, the influence on the insertability of both the connector housings 15 and 17 is reduced. That is, rattling is suppressed without reducing insertability.

図６は図２に示した雄コネクタハウジングの側面図である。
この実施の形態では、突起５１及び凹部５３が略同径に形成されている。より正確には、略同一半径の球面の一部分で形成されている。球状とすることにより、突起５１は、凹部５３の中心（最深部）に留まろうとするので、３６０度方向の動きを抑えることができる。突起５１及び凹部５３が略同径となることで、隙間のない嵌め合いとなり、突起５１が凹部５３に入り込んだ状態で、コネクタ嵌合方向ａ及びコネクタ嵌合直交方向ｂ（図５，図６参照）の相対移動の規制作用を高めることができる。 6 is a side view of the male connector housing shown in FIG.
In this embodiment, the protrusion 51 and the recess 53 are formed with substantially the same diameter. More precisely, it is formed by a part of a spherical surface having substantially the same radius. By making it spherical, the protrusion 51 tries to stay at the center (deepest part) of the recess 53, and therefore, the movement in the 360 degree direction can be suppressed. Since the protrusion 51 and the recess 53 have substantially the same diameter, the fitting is performed without a gap, and the connector fitting direction a and the connector fitting orthogonal direction b (see FIGS. 5 and 6) in a state where the protrusion 51 enters the recess 53. The relative movement restricting action of (see) can be enhanced.

なお、突起５１及び凹部５３は、球面状となることで、以下の効果も有する。すなわち、３６０度方向の動きを抑える作用は、球面状以外にピラミット形、円錐形等の相補的な凹凸形状においても得られるが、これらピラミット形、円錐形等の凹凸形状では、先端が細い（稜線がエッジとなる）ので、振動による相対的な摺接により力が集中して変形する可能性がある。このような変形は、突起５１及び凹部５３のガタツキ抑止作用を急激に低下させる。これに対し、本実施の形態のような球面状とすることで力の集中が少なく変形を生じ難くできる。 In addition, the protrusion 51 and the recessed part 53 have the following effects because they are spherical. That is, the action of suppressing the movement in the 360-degree direction can be obtained not only in a spherical shape but also in a complementary concave-convex shape such as a pyramid shape or a conical shape, but in the concave-convex shape such as a pyramid shape or a conical shape, the tip is thin ( Therefore, there is a possibility that force is concentrated and deformed due to relative sliding contact due to vibration. Such deformation abruptly reduces the rattling prevention action of the protrusion 51 and the recess 53. On the other hand, the spherical shape as in this embodiment reduces the concentration of force and makes it difficult to cause deformation.

また、振動以外に、突起５１及び凹部５３が球面状であると、コネクタ挿入離脱時に加わる力に対しても上記同様に変形が生じ難い。さらに、球面状であると、コネクタ挿入離脱時の傾きを配慮しなくてもよい。例えばピラミット形とした構成では、コネクタ挿入時に傾きが生じると、稜線が潰れて変形する不具合が生じる。球面状とすることによりこのような問題も生じ難くできる。 In addition to vibration, if the protrusion 51 and the recess 53 are spherical, deformation is unlikely to occur in the same manner as described above with respect to the force applied when the connector is inserted and removed. Furthermore, if it is spherical, it is not necessary to consider the inclination when the connector is inserted and removed. For example, in the configuration of the pyramid shape, if an inclination occurs when the connector is inserted, the ridgeline is crushed and deformed. Such a problem can be made difficult to occur by using a spherical shape.

突起５１及び凹部５３は、両コネクタハウジング１５，１７の両側面のそれぞれに少なくとも２組形成されている。２組の離間方向は任意でよい。それぞれの側面に、突起５１及び凹部５３が２組設けられていることで、２箇所で動きを抑えられ、より大きな荷重（振動荷重）に耐えることが可能となる。突起５１及び凹部５３が１組の場合には、嵌り状態における突起５１及び凹部５３の球面中心Ｏ１，Ｏ２（図１０参照）を通りコネクタ嵌合方向ａに直交する直線Ｌ（図１０参照）を軸に、両コネクタハウジング１５，１７が相対回転可能となるが、２組とすることでこの相対回転が規制され、ガタツキが生じ難くなる。 At least two sets of protrusions 51 and recesses 53 are formed on both side surfaces of the connector housings 15 and 17, respectively. The two sets of separation directions may be arbitrary. By providing two sets of projections 51 and recesses 53 on each side surface, the movement can be suppressed at two locations, and a larger load (vibration load) can be withstood. When the projection 51 and the recess 53 are a set, a straight line L (see FIG. 10) passing through the spherical centers O1 and O2 (see FIG. 10) of the projection 51 and the recess 53 in the fitted state and orthogonal to the connector fitting direction a. Both the connector housings 15 and 17 can be rotated relative to each other on the shaft, but the relative rotation is restricted by two sets, and rattling is less likely to occur.

次に、上記のように構成されたコネクタの作用を説明する。
図７は両コネクタハウジングの嵌合前を（ａ）、嵌合途中を（ｂ）、嵌合完了を（ｃ）で示した嵌合過程を表す平断面図、図８は図７の嵌合途中Ｃ部拡大図、図９は嵌合完了状態の要部拡大図である。
コネクタ１００を嵌合するには、図１に示した回転ロックレバー３３をアンロック位置に配置させた状態で、雌コネクタハウジング１５の受入部３１に、雄コネクタハウジング１７の結合先端部３５を挿入する。受入部３１に結合先端部３５を挿入していくと、雄コネクタハウジング１７の凸部３７，３７と、ロック部３９とが回転ロックレバー３３の不図示のロック部受け入れ部に進入し、雌コネクタハウジング１５と雄コネクタハウジング１７が半嵌合状態となる。 Next, the operation of the connector configured as described above will be described.
FIG. 7 is a cross-sectional plan view showing the fitting process in which both connector housings are shown in (a), in the middle of fitting (b), and in the fitting process in (c). FIG. The C part enlarged view on the way, FIG. 9 is the principal part enlarged view of a fitting completion state.
To fit the connector 100, the coupling tip 35 of the male connector housing 17 is inserted into the receiving part 31 of the female connector housing 15 with the rotation lock lever 33 shown in FIG. To do. When the coupling tip portion 35 is inserted into the receiving portion 31, the convex portions 37, 37 of the male connector housing 17 and the lock portion 39 enter the lock portion receiving portion (not shown) of the rotation lock lever 33, and the female connector. The housing 15 and the male connector housing 17 are in a semi-fitted state.

次いで、回転ロックレバー３３を回動し、アンロック位置からロック位置側に倒していくと、凸部３７，３７が不図示のロック位置に移動し、図７（ｂ）に示すように、両コネクタハウジング１５，１７の嵌合動作が進行する。この際、図８に示すように、フード部２１の内壁面４７から突出する突起５１が雄コネクタハウジング１７の結合先端部３５の先端に当たる。さらに嵌合が進むと、フード部２１が撓んで持ち上がり、突起５１の先端が雄コネクタハウジング１７の外壁面４９上を進む。 Next, when the rotation lock lever 33 is rotated and tilted from the unlock position to the lock position side, the convex portions 37 and 37 move to a lock position (not shown), and as shown in FIG. The fitting operation of the connector housings 15 and 17 proceeds. At this time, as shown in FIG. 8, the protrusion 51 protruding from the inner wall surface 47 of the hood portion 21 hits the distal end of the coupling distal end portion 35 of the male connector housing 17. As the fitting further proceeds, the hood portion 21 is bent and lifted, and the tip of the protrusion 51 advances on the outer wall surface 49 of the male connector housing 17.

この状態からさらに回転ロックレバー３３を回動していき、回転ロックレバー３３をロック位置に配置すると、雌コネクタハウジング１５と雄コネクタハウジング１７が完全嵌合し、図７（ｃ）に示すように、突起５１が凹部５３に達する。突起５１は、フード部２１の薄肉部５５の撓みによる反発力で図９に示すように凹部５３に嵌る。突起５１は、凹部５３に入り込んだ状態に保たれ、これにより、両コネクタハウジング１５，１７のコネクタ嵌合方向ａ及びコネクタ嵌合直交方向ｂの相対移動が規制され、ガタが生じ難くなる。なお、ここでの「撓み」とは、弾性変形及び塑性変形を含む広義の変形を言う。 When the rotation lock lever 33 is further rotated from this state and the rotation lock lever 33 is disposed at the lock position, the female connector housing 15 and the male connector housing 17 are completely fitted, as shown in FIG. The protrusion 51 reaches the recess 53. The protrusion 51 fits into the recess 53 as shown in FIG. 9 due to the repulsive force caused by the bending of the thin portion 55 of the hood portion 21. The protrusion 51 is kept in the recessed portion 53, thereby restricting relative movement of the connector housings 15, 17 in the connector fitting direction “a” and the connector fitting orthogonal direction “b”, so that rattling is less likely to occur. Here, “deflection” refers to deformation in a broad sense including elastic deformation and plastic deformation.

このコネクタ完全嵌合状態では、回転ロックレバー３３により雌コネクタハウジング１５と雄コネクタハウジング１７が離脱不能にロックされ、その嵌合状態が維持され、しかも、突起５１がフード部２１の弾性復元力により凹部５３を押圧する状態に維持される。同時に、雌端子４５の箱形の電気接触部内に雄端子４３の平板形の電気接触部が挿入されており、雌雄端子４５，４３の電気接触部同士が電気的に接続される。 In this connector fully fitted state, the female connector housing 15 and the male connector housing 17 are locked so as not to be detached by the rotation lock lever 33, and the fitted state is maintained. Moreover, the protrusion 51 is caused by the elastic restoring force of the hood portion 21. The state of pressing the recess 53 is maintained. At the same time, the flat electrical contact portion of the male terminal 43 is inserted into the box-shaped electrical contact portion of the female terminal 45, and the electrical contact portions of the male and female terminals 45 and 43 are electrically connected to each other.

本実施の形態に係るコネクタ１００は、上記した構成を基本として有するが、本発明に係るコネクタは、以下の各変形例に係る構成を備えることもできる。
図１０は凹部が大径に形成された変形例に係るコネクタの凹部及び突起の断面図である。
この変形例は、凹部５３Ａが突起５１より大径に形成されるとともに、両者の球面中心Ｏ１，Ｏ２と接触点Ｓ１を通る直線Ｌがコネクタ嵌合方向ａに直交する。 The connector 100 according to the present embodiment has the above-described configuration as a basis, but the connector according to the present invention can also include configurations according to the following modifications.
FIG. 10 is a cross-sectional view of a recess and a protrusion of a connector according to a modification in which the recess has a large diameter.
In this modification, the recess 53A is formed to have a larger diameter than the protrusion 51, and the straight line L passing through the spherical centers O1, O2 and the contact point S1 is orthogonal to the connector fitting direction a.

この変形例では、大径の凹部５３Ａの内に小径の突起５１が入って突起５１の先端が凹部５３Ａの最深部に当接する。両者の球面中心Ｏ１，Ｏ２と接触点Ｓ１を通る直線Ｌがコネクタ嵌合方向ａに直交することで、両コネクタハウジング１５，１７の嵌合方向ａに直交する方向ｂの相対移動が規制される。また、突起５１が凹部５３Ａの最深部に接しているので、コネクタ嵌合方向ａの相対移動（球状凹面を矢印ｄ方向に這い上がろうとする移動）にも突起５１は凹部５３Ａの球面から反力を受けることとなり、この反力が両コネクタハウジング１５，１７のコネクタ嵌合方向ａにおける相対移動の規制力として働く。 In this modification, the small-diameter protrusion 51 enters the large-diameter recess 53A, and the tip of the protrusion 51 contacts the deepest portion of the recess 53A. Since the straight line L passing through the spherical centers O1 and O2 and the contact point S1 is orthogonal to the connector fitting direction a, relative movement in the direction b perpendicular to the fitting direction a of both the connector housings 15 and 17 is restricted. . In addition, since the protrusion 51 is in contact with the deepest part of the recess 53A, the protrusion 51 is opposite from the spherical surface of the recess 53A even in relative movement in the connector fitting direction a (movement that attempts to scoop up the spherical concave surface in the direction of arrow d). The reaction force acts as a force for restricting relative movement of the connector housings 15 and 17 in the connector fitting direction a.

次に、凹部５３Ａと突起５１の位置をずらした変形例を説明する。
図１１はハウジング相互当接部の反対側に接触点を位置させる変形例に係るコネクタの要部拡大図、図１２は図１１に示した凹部及び突起の拡大図である。
この変形例は、凹部５３Ａと突起５１の位置をずらして構成される。より具体的には、図１２に示すように、凹部５３Ａの球面中心Ｏ２を通りコネクタ嵌合方向ａに直交する直線Ｌを挟んでハウジング相互当接部５７の反対側に接触点Ｓ１が位置する。ハウジング相互当接部５７は、例えば図１１に示す端子収容室２５の先端面２９と、雄コネクタハウジング１７の端子収容室受入開口部４１における受入部座面５９とすることができる。なお、ハウジング相互当接部５７は、この他の部位であってもよい。 Next, a modified example in which the positions of the recess 53A and the protrusion 51 are shifted will be described.
FIG. 11 is an enlarged view of a main part of a connector according to a modified example in which the contact point is positioned on the opposite side of the housing mutual contact part, and FIG. 12 is an enlarged view of the concave part and the protrusion shown in FIG.
In this modification, the positions of the recess 53A and the protrusion 51 are shifted. More specifically, as shown in FIG. 12, the contact point S1 is located on the opposite side of the housing mutual contact portion 57 across the straight line L passing through the spherical center O2 of the recess 53A and orthogonal to the connector fitting direction a. . The housing mutual contact portion 57 can be, for example, a front end surface 29 of the terminal accommodating chamber 25 shown in FIG. 11 and a receiving portion seating surface 59 in the terminal accommodating chamber receiving opening 41 of the male connector housing 17. The housing mutual contact portion 57 may be another part.

図１１に示すように、一対の凹部５３Ａ，５３Ａ同士の距離Ｐと、一対の突起５１，５１同士の距離Ｐは、一致している。一方。ハウジング相互当接部５７に近い凹部５３Ａの距離Ｋは、ハウジング相互当接部５７に近い突起５１の距離Ｋ１より小さく設定されている（Ｋ＜Ｋ１）。なお、この変形例では、凹部５３Ａが大径であるが、凹部５３Ａは突起５１と同径の凹部５３であってもよい。 As shown in FIG. 11, the distance P between the pair of recesses 53A and 53A and the distance P between the pair of protrusions 51 and 51 are the same. on the other hand. The distance K of the recess 53A close to the housing mutual contact portion 57 is set smaller than the distance K1 of the protrusion 51 close to the housing mutual contact portion 57 (K <K1). In this modification, the concave portion 53A has a large diameter, but the concave portion 53A may be the concave portion 53 having the same diameter as the protrusion 51.

この変形例によれば、図１１に示すように、両コネクタハウジング１５，１７の嵌合が完了すると、ハウジング相互当接部５７が当接状態となり、それ以上の嵌合方向の相対移動が阻止される。この状態で、図１２に示すように、凹部５３Ａの球面中心Ｏ２を通り嵌合方向ａに直交する直線Ｌを挟んでハウジング相互当接部５７の反対側に接触点Ｓ１が位置する。つまり、接触点Ｓ１が凹部５３Ａの最深部６１に一致していない。したがって、フード部２１は薄肉部５５が撓んで持ち上がり、その撓み復元力が接触点Ｓ１に加わる。このことで、凹部５３Ａと突起５１には、突起５１の接触点Ｓ１と凹部５３Ａの最深部６１をちかづけようとする力（求心力）が相互に働く。 According to this modification, as shown in FIG. 11, when the fitting of the two connector housings 15 and 17 is completed, the housing mutual abutting portion 57 is brought into the abutting state, and further relative movement in the fitting direction is prevented. Is done. In this state, as shown in FIG. 12, the contact point S1 is located on the opposite side of the housing mutual contact portion 57 across the straight line L passing through the spherical center O2 of the recess 53A and orthogonal to the fitting direction a. That is, the contact point S1 does not coincide with the deepest portion 61 of the recess 53A. Accordingly, the thin portion 55 of the hood portion 21 is bent and lifted, and the bending restoring force is applied to the contact point S1. As a result, a force (centripetal force) is exerted on the recess 53A and the protrusion 51 so as to cause the contact point S1 of the protrusion 51 and the deepest portion 61 of the recess 53A to flicker.

この力は、雌コネクタハウジング１５では、端子収容室２５の先端面２９を受入部座面５９に押圧する方向の力となり、雄コネクタハウジング１７では、受入部座面５９を端子収容室２５の先端面２９に押圧する方向の力となる。つまり、ハウジング相互当接部５７で当接面２９，５９同士をより強く当接させる力が常時作用する。これにより、嵌合解除方向ａへの移動が生じ難くなる。同時に、凹部５３Ａの球面が突起５１から強く押圧されていることにより、両コネクタハウジング１５，１７の嵌合方向ａに直交する方向ｂの相対移動も規制され、ガタツキが生じ難くなる。 In the female connector housing 15, this force is a force in a direction in which the distal end surface 29 of the terminal accommodating chamber 25 is pressed against the receiving portion seating surface 59, and in the male connector housing 17, the receiving portion seating surface 59 serves as the distal end of the terminal accommodating chamber 25. This is the force in the direction of pressing against the surface 29. That is, a force that causes the contact surfaces 29 and 59 to contact each other more strongly at the housing mutual contact portion 57 always acts. Thereby, the movement to the fitting release direction a becomes difficult to occur. At the same time, since the spherical surface of the recess 53A is strongly pressed from the protrusion 51, the relative movement in the direction b perpendicular to the fitting direction a of the connector housings 15 and 17 is also restricted, and rattling is less likely to occur.

したがって、本実施の形態に係るコネクタ１００によれば、フード部２１の内壁面４７と雄コネクタハウジング１７の外壁面４９とに、半球状の突起５１又はこの突起５１を係止可能にする半球面状の凹部５３を設け、両コネクタハウジング１５，１７の嵌合時、突起５１と凹部５３とを圧接状態で係合するので、二重のハウジング構造やバネを除いた簡素な構造で両コネクタハウジング１５，１７の相対移動を規制することができるようになり、特に耐振機能を付与するコネクタ１００の部品点数を削減し、低コスト化、軽量化を達成することができる。 Therefore, according to the connector 100 according to the present embodiment, the hemispherical protrusion 51 or the hemispherical surface that enables the protrusion 51 to be locked to the inner wall surface 47 of the hood portion 21 and the outer wall surface 49 of the male connector housing 17. When the two connector housings 15 and 17 are fitted together, the protrusion 51 and the recess 53 are engaged with each other in a pressure contact state. Therefore, both connector housings have a double housing structure or a simple structure excluding a spring. The relative movement of 15 and 17 can be restricted, and the number of parts of the connector 100 that provides the vibration proof function can be reduced, and the cost and weight can be reduced.
