Description

本発明は、例えば自動車内に配設されたワイヤーハーネスの接続に用いられるコネクタ構造に関し、とりわけ、雌雄いずれかのコネクタ内に収容保持されサブコネクタを備えたコネクタ構造に関する。   The present invention relates to a connector structure used for connection of, for example, a wire harness disposed in an automobile, and more particularly to a connector structure that is accommodated and held in one of male and female connectors and includes a sub-connector.

自動車の電気機器類にワイヤーハーネスを接続したり、ワイヤーハーネス同士を分岐接続するために用いられるコネクタ構造としては、以下の特許文献1に記載されているものが知られている。   What is described in the following patent documents 1 is known as a connector structure used in order to connect a wire harness to the electric equipment of a car, or to branch-connect wire harnesses.

概略を説明すれば、このコネクタは、複数の雌端子を収容可能な雌コネクタと、この雌コネクタの雌端子と対応する雄端子が内部に収容されて、前記雌コネクタに嵌合される雄コネクタと、を備えている。   Briefly, this connector includes a female connector that can accommodate a plurality of female terminals, and a male connector that accommodates a female terminal corresponding to the female terminal of the female connector and is fitted to the female connector. And.

前記雌コネクタのハウジングの外周には、これら雌コネクタと雄コネクタとを低荷重で容易に嵌合することができるレバーが回動自在に保持されている。このレバーは、前記ハウジングを覆うようにほぼU字形状に形成されて、基端部が前記ハウジングの左右の外面に回転可能に連結されており、梃子の原理によって雌コネクタを雄コネクタに嵌合方向への荷重を付与して互いに嵌合させるようになっている。   On the outer periphery of the housing of the female connector, a lever capable of easily fitting the female connector and the male connector with a low load is rotatably held. This lever is formed in a substantially U shape so as to cover the housing, and the base end portion is rotatably connected to the left and right outer surfaces of the housing, and the female connector is fitted to the male connector by the lever principle. A load in the direction is applied to be fitted to each other.

また、前記ハウジングの内部に形成されたコネクタ収容部内には、複数の雌端子を収容可能なサブコネクタが収容保持されている。このサブコネクタは、車両や電気機器類の仕様などに合わせて、複数のワイヤーハーネスを適宜選択して前記雌コネクタに接続させるためのものであって、前記ハウジング内に係止機構を介して収容保持されている。   A sub-connector capable of accommodating a plurality of female terminals is accommodated and held in a connector accommodating portion formed inside the housing.

特開2008−300236号公報JP 2008-300366 A

前記従来のコネクタ構造にあっては、サブコネクタが、ハウジング内に係止機構によって収容保持されているが、各コネクタの接続作業中などに、前記ワイヤーハーネスを介してサブコネクタに、前記係止機構の係止力以上の引っ張り荷重が掛かった場合に、該サブコネクタが前記コネクタ収容部から不用意に抜け出てしまうおそれがある。   In the conventional connector structure, the sub-connector is accommodated and held in the housing by the locking mechanism. However, during the connection work of each connector, the locking is performed on the sub-connector via the wire harness. When a tensile load greater than the locking force of the mechanism is applied, the sub-connector may accidentally come out of the connector housing portion.

この結果、サブコネクタ内の雌端子と前記雄コネクタの雄端子との結合が不安定になったり、場合によっては両者の接続が解除されてしまう。   As a result, the connection between the female terminal in the sub-connector and the male terminal of the male connector becomes unstable, or in some cases, the connection between the two is released.

本発明は、前記従来のコネクタ構造の技術的課題に鑑みて案出されたもので、サブコネクタに抜け出し方向の大きな荷重が作用しても、該サブコネクタをコネクタ収容部内で確実に保持し得るコネクタ構造を提供する。   The present invention has been devised in view of the technical problem of the conventional connector structure, and even when a large load in the pull-out direction acts on the sub-connector, the sub-connector can be reliably held in the connector housing portion. Provide a connector structure.

請求項1に記載の発明は、内部に雌雄いずれか一方の端子が挿通保持された一方側コネクタと、内部に前記雌雄いずれか他方の端子が挿通保持され、前記一方側コネクタに嵌合して前記一方の端子に他方の端子を接続する他方側コネクタと、前記一方側コネクタの内部に形成されたコネクタ収容部内に収容保持されたサブコネクタと、前記他方側コネクタに設けられた支点部を支点として可動自在に保持されて、可動操作されることによって前記両コネクタを嵌合させる方向へ付勢力を付与するレバーと、を備えたコネクタ構造であって、
前記一方側コネクタに、前記レバー可動操作時の作用点となる作用部を設けると共に、前記サブコネクタとレバーとの間に、前記レバーの少なくとも前記両コネクタを嵌合させる最大可動位置で、サブコネクタの抜け方向の移動を規制する規制手段を設けたことを特徴としている。
According to the first aspect of the present invention, one of the male and female terminals is inserted and held inside, and the other terminal of the male and female is inserted and held inside, and is fitted to the one side connector. The other side connector for connecting the other terminal to the one terminal, a sub-connector housed and held in a connector housing part formed inside the one side connector, and a fulcrum part provided on the other side connector A lever structure that is held movably as a lever and applies a biasing force in a direction in which the two connectors are fitted by being operated movably,
The one-side connector is provided with an action portion serving as an action point at the time of the lever moving operation, and the sub-connector is at a maximum movable position where the two connectors of the lever are fitted between the sub-connector and the lever. It is characterized in that there is provided a restricting means for restricting movement in the pulling direction.

請求項2に記載の発明は、前記規制手段を、前記サブコネクタの上面に突設された規制ボス部と、前記レバーに形成されて、該レバーの最大可動位置で、前記サブコネクタの抜け出し方向から前記規制ボス部の外周面に対峙する規制部と、から構成したことを特徴としている。   According to a second aspect of the present invention, the regulating means includes a regulating boss portion projecting from the upper surface of the sub-connector and the lever, and the pull-out direction of the sub-connector at the maximum movable position of the lever. And a restricting portion facing the outer peripheral surface of the restricting boss portion.

請求項3に記載の発明は、前記規制手段の規制部を、前記レバーの可動軌跡にほぼ沿って形成されて前記規制ボス部の外周面に対峙する規制長孔によって形成したことを特徴としている。   The invention according to claim 3 is characterized in that the restricting portion of the restricting means is formed by a restricting long hole formed substantially along the movable locus of the lever and facing the outer peripheral surface of the restricting boss portion. .

請求項1に記載の発明によれば、レバーを最大可動位置に可動操作すると、雌雄コネクタの確実な嵌合が得られると同時に、規制手段が働くことから、前記サブコネクタに抜け出し方向の大きな荷重が作用しても、該サブコネクタのコネクタ収容部からの抜け出しを確実に規制することができる。   According to the first aspect of the present invention, when the lever is moved to the maximum movable position, the male and female connectors can be surely fitted, and at the same time, the regulating means works. Even if this works, the withdrawal of the sub-connector from the connector housing portion can be reliably regulated.

しかも、前記規制手段の規制作動が、少なくともレバーの最大可動位置で初めて働くようにしたため、前記レバーの可動操作中に摺動抵抗によって可動操作力が大きくなるなどの悪影響を与えることがない。   In addition, since the restricting operation of the restricting means works for the first time at least at the maximum movable position of the lever, there is no adverse effect such as an increase in the movable operating force due to sliding resistance during the movable operation of the lever.

請求項2に記載の発明によれば、規制手段を、単にサブコネクタの規制ボス部とレバーの規制部とによって構成したため、この構造が簡単であり、製造作業が容易であると共に、コストの高騰を抑制できる。   According to the second aspect of the present invention, since the restricting means is simply constituted by the restricting boss portion of the sub-connector and the restricting portion of the lever, this structure is simple, the manufacturing work is easy, and the cost increases. Can be suppressed.

請求項3に記載の発明によれば、前記規制手段の作動をレバーの可動操作、つまり規制長孔によって可動軌跡を利用したことから、該レバーの有効利用が図れる。この結果、規制手段によるサブコネクタの規制作業が簡単になる。   According to the third aspect of the present invention, the lever can be effectively used because the movement of the restricting means is operated by a movable operation of the lever, that is, the movable locus is used by the restriction long hole. As a result, the restriction work of the sub connector by the restriction means is simplified.

この両規制長孔19,19は、前記レバー4の回動軌跡に沿ってほぼく字形状に形成された外側端部19aと内側端部19bとからなり、レバー4の回動中には内面が前記規制ボス部12の外周面に摺接することなく、一定の微小隙間をもって移動するが、レバー4の最大回動位置、つまり図9に示す雌雄コネクタ1,2が最終的に深く嵌合した位置で内側端部19bの内面が前記各規制ボス部12の外周面と僅かに接触するように形成されている。また、前記両規制長孔19,19の各先端には、該規制長孔19、19の先端部の開き方向の変形を抑制するブリッジ19c、19cが設けられている。   Both the regulation long holes 19, 19 are composed of an outer end portion 19 a and an inner end portion 19 b formed in a substantially square shape along the turning locus of the lever 4. 9 moves without a slidable contact with the outer peripheral surface of the restricting boss portion 12, but moves with a certain minute gap, but the maximum rotation position of the lever 4, that is, the male and female connectors 1 and 2 shown in FIG. The inner end portion 19b is formed so that the inner surface of the inner end portion 19b is slightly in contact with the outer peripheral surface of each regulating boss portion 12. In addition, bridges 19c and 19c that suppress deformation in the opening direction of the distal ends of the restriction long holes 19 and 19 are provided at the tips of the restriction long holes 19 and 19, respectively.

前記連結把持部4bは、図6及び図7に示すように、内部に前記コネクタ本体5の前記係止爪5gに係止する係止フック部20が一体に設けられている。この係止フック部20は、前記各レバー片4aが前記コネクタ部6の上下壁の各外面を摺接しながら回動して雌雄コネクタ1,2が最終的に嵌合した時点で前記係止爪5gに係止することによって雌雄コネクタ1,2の嵌合力を強化するものである。   As shown in FIGS. 6 and 7, the connection grip portion 4 b is integrally provided with a locking hook portion 20 that locks with the locking claw 5 g of the connector body 5. The locking hook portion 20 is configured such that when the lever pieces 4a rotate while slidingly contacting the outer surfaces of the upper and lower walls of the connector portion 6 and the male and female connectors 1 and 2 are finally fitted, the locking claws By engaging with 5 g, the fitting force of the male and female connectors 1 and 2 is strengthened.

以下、本実施形態の前記雌コネクタ1と雄コネクタ2を結合する基本動作を説明する。   Hereinafter, a basic operation for coupling the female connector 1 and the male connector 2 of the present embodiment will be described.

すなわち、まず、予め雌コネクタ1のコネクタ収容溝7に、サブコネクタ3を収容する。つまり、図3Aに示すように、サブコネクタ3の各先端部をコネクタ収容溝7の後端側開口部から内部に挿入するが、このとき、前記拡巾な上側の嵌合突部8bをガイド溝6bに沿って押し込むと、斯かるガイド溝6bに沿ってスムーズに前方へスライド案内される。サブコネクタ3を、そのまま奥まで押し込むと、図3Bに示すように、前記両係止凸部8c、8cが、コネクタ収容溝7の両突出部7c、7cに突き当たってそれ以上の移動が規制されると同時に、サブコネクタ3のスライド移動中に外方へ弾性変形していた前記両係止爪7d、7dが原状復帰して前記両係止凸部8c、8cの後端縁に係止する。これによって、サブコネクタ3は、前方への最大移動位置が規制されると共に、後方への抜け出しが抑制される。なお、この時点では、サブコネクタ3には、予め各端子収容孔8aにワイヤーハーネスH1が接続された複数雌端子11が挿通固定されている。   That is, first, the subconnector 3 is accommodated in the connector accommodating groove 7 of the female connector 1 in advance. That is, as shown in FIG. 3A, each tip end portion of the sub-connector 3 is inserted into the inside from the rear end side opening portion of the connector receiving groove 7, and at this time, the widened upper fitting projection portion 8b is guided as a guide. When pushed in along the groove 6b, the guide is smoothly slid forward along the guide groove 6b. When the sub-connector 3 is pushed in as it is, as shown in FIG. At the same time, the locking claws 7d and 7d that have been elastically deformed outward during the sliding movement of the sub-connector 3 are restored to their original shapes and locked to the rear end edges of the locking protrusions 8c and 8c. . Thereby, the sub connector 3 is restricted in its maximum forward movement position and is prevented from coming out backward. At this time, a plurality of female terminals 11 each having a wire harness H1 connected to each terminal accommodating hole 8a are inserted and fixed in advance in the sub-connector 3.

一方、前記雄コネクタ2には、図6及び図7に示すように、予め、前記各スリット15,15を介して前記レバー4の両レバー片4a、4aが挿入されていると共に、前記各支点ボス部16にレバー片4a、4aの各支点用孔17が回動自在に嵌合されている。   On the other hand, as shown in FIGS. 6 and 7, both the lever pieces 4a and 4a of the lever 4 are inserted into the male connector 2 in advance through the slits 15 and 15, and the fulcrums are provided. Each fulcrum hole 17 of the lever pieces 4a, 4a is fitted to the boss portion 16 so as to be rotatable.

続いて、図8に示すように、雌コネクタ1に雄コネクタ2を嵌合するわけであるが、このとき、雌コネクタ1の上下の作用ボス部10とサブコネクタ3の上下の規制ボス部12に、これらに対応する前記レバー4の上下のカム孔18と規制長孔19を外側端部19a側から嵌合させておく。   Subsequently, as shown in FIG. 8, the male connector 2 is fitted to the female connector 1. At this time, the upper and lower action boss portions 10 of the female connector 1 and the upper and lower restricting boss portions 12 of the subconnector 3 are used. Further, the upper and lower cam holes 18 and the restriction long holes 19 of the lever 4 corresponding to these are fitted from the outer end 19a side.

その後、前記レバー4を、連結把持部4bを把持しながら支点ボス部16を支点として図8の時計方向(矢印方向)に回動させると、前記各カム孔18の内周面が作動ボス部10の外周面に摺接しつつ雌雄コネクタ1,2を互いに引き付ける方向に付勢力が作用すると同時に、規制ボス部12が規制長孔19内を移動する。そして、前記レバー4が、図9に示すように、時計方向に回動させると、レバー4の係止フック部20が内方へ弾性変形しながら係止爪5gを乗り越えながら、該係止爪5gに係止する。これによって、レバー4は最大回動位置に確実に保持されると共に、前記雌雄コネクタ1,2の各端子間の強固な嵌合状態が得られる。   Thereafter, when the lever 4 is rotated clockwise (in the direction of the arrow) in FIG. 8 with the fulcrum boss 16 as a fulcrum while gripping the connection grip 4b, the inner peripheral surface of each cam hole 18 is an operating boss. The urging force acts in the direction in which the male and female connectors 1 and 2 are attracted to each other while being in sliding contact with the outer peripheral surface of the boss 10, and at the same time, the restriction boss portion 12 moves in the restriction slot 19. Then, when the lever 4 is rotated clockwise as shown in FIG. 9, the locking hook portion 20 of the lever 4 is elastically deformed inward and gets over the locking claw 5g. Lock to 5g. As a result, the lever 4 is securely held at the maximum rotation position, and a strong fitting state between the terminals of the male and female connectors 1 and 2 is obtained.

しかも、このレバー4の最大回動位置では、図9に示すように、規制長孔19の内側端部19bがサブコネクタ3のコネクタ収容溝7への挿入方向に対してほぼ直角方向になって、該内側端部19bがサブコネクタ3の規制ボス部12に図中水平方向に配置される。つまり、前記内側端部19bが規制ボス部12を介してサブコネクタ3の抜け出し方向(図中矢印方向)への移動を確実に規制する。   Moreover, at the maximum rotation position of the lever 4, as shown in FIG. 9, the inner end 19 b of the restriction long hole 19 is substantially perpendicular to the insertion direction of the sub connector 3 into the connector receiving groove 7. The inner end portion 19b is disposed on the restriction boss portion 12 of the sub-connector 3 in the horizontal direction in the figure. That is, the inner end portion 19b reliably restricts the movement of the sub connector 3 in the withdrawal direction (arrow direction in the figure) via the restricting boss portion 12.

このため、前記サブコネクタ3に、過大な抜け出し方向(図中矢印方向)の引っ張り荷重が作用して、前記係止凸部8c、8cと係止爪7d、7dとの係止状態が解除されるような引っ張り荷重であったとしても、前記規制ボス部12が規制長孔19の内側端部19bの内面に当接して大きな規制力が働く。したがって、サブコネクタ3のコネクタ収容溝7からの不用意な抜け出しを確実に抑制できる。   For this reason, an excessive pulling load in the pull-out direction (arrow direction in the figure) acts on the sub-connector 3, and the locking state between the locking projections 8c, 8c and the locking claws 7d, 7d is released. Even if it is such a tensile load, the restriction boss portion 12 comes into contact with the inner surface of the inner end portion 19b of the restriction long hole 19 and a large restriction force acts. Therefore, inadvertent withdrawal of the sub connector 3 from the connector receiving groove 7 can be reliably suppressed.

また、前記規制ボス部12は、レバー4が前記最大の回動位置まで回動する過程では、外周面が前記規制長孔19とは摺接せずに該規制長孔19内を移動することから、レバー4の回動時の摺動抵抗にはならない。したがって、前記レバー4の回動操作性に影響を与えることがない。   Further, in the process in which the lever 4 rotates to the maximum rotation position, the restriction boss portion 12 moves in the restriction slot 19 without the outer peripheral surface being in sliding contact with the restriction slot 19. Therefore, it does not become a sliding resistance when the lever 4 is rotated. Therefore, the operability of the lever 4 is not affected.

但し、前記レバー4の回動操作時に、大きな摺動抵抗が発生しない程度で、前記規制長孔19の内面を規制ボス部12の外周面に摺接させることも可能である。   However, the inner surface of the restriction long hole 19 can be slidably contacted with the outer peripheral surface of the restriction boss portion 12 so that a large sliding resistance is not generated when the lever 4 is turned.

さらに、前記カム孔18と規制長孔19の各先端部には、それぞれブリッジ18a、19cが一体に設けられて、これらが補強部として機能することから、前記レバー4の回動時に各カム孔18と各規制長孔19に、たとえ開き方向の荷重が作用しても、カム孔18と規制長孔19が不用意に開くことがなく、十分な剛性を維持できる。この結果、前記レバー4の耐久性が向上する。   Further, bridges 18a and 19c are integrally provided at the respective distal end portions of the cam hole 18 and the regulation long hole 19, and these function as a reinforcing portion, so that each cam hole is rotated when the lever 4 is rotated. Even if a load in the opening direction is applied to 18 and each restriction long hole 19, the cam hole 18 and the restriction long hole 19 do not open carelessly, and sufficient rigidity can be maintained. As a result, the durability of the lever 4 is improved.

また、前記サブコネクタ3に対する規制を、レバー4の回動操作を利用して行うようにしたため、該レバー4の回動の有効利用が図れ、この結果、規制手段によるサブコネクタの規制作業が簡単になる。   Further, since the restriction on the sub-connector 3 is performed by utilizing the turning operation of the lever 4, the turning of the lever 4 can be effectively used. As a result, the restriction work of the sub-connector by the restriction means is simple. become.

本発明は、前記実施形態の構成に限定されるものではなく、コネクタの仕様によっては、一方側コネクタを雄コネクタとし、他方側コネクタを雌コネクタとすることも可能である。この場合、サブコネクタ3の端子収容部には、雄端子を収容保持することになる。   The present invention is not limited to the configuration of the above embodiment, and depending on the specifications of the connector, the one-side connector can be a male connector and the other-side connector can be a female connector. In this case, the male terminal is accommodated and held in the terminal accommodating portion of the sub-connector 3.

また、前記レバー4の構造もコネクタの仕様やレイアウトなどに応じて任意に変更することが可能である。   Also, the structure of the lever 4 can be arbitrarily changed according to the specifications and layout of the connector.

さらに、前記規制手段として、雌雄コネクタ1,2に別途設ける必要がなく、単に既存の前記レバー4や雌コネクタ1を利用して形成できるので、製造作業や組立作業が容易であり、製造コストや組立作業コストの高騰を抑制できる。   Furthermore, as the restricting means, it is not necessary to separately provide the male and female connectors 1 and 2 and can be formed simply using the existing lever 4 or female connector 1, so that the manufacturing operation and the assembly operation are easy, and the manufacturing cost and Increase in assembly work costs can be suppressed.

また、規制手段の規制部として、前記規制長孔19の他に、規制ボス部12の上端が被嵌状態になる長溝状に形成することも可能である。   Further, as the restricting portion of the restricting means, in addition to the restricting long hole 19, it is also possible to form a long groove shape in which the upper end of the restricting boss portion 12 is fitted.
