Description

本明細書によって開示される技術は、コネクタに関する。   The technology disclosed by this specification is related with a connector.

例えば、雄コネクタに嵌合される雌コネクタとして特開２０１２−２８０７３号公報（特許文献１）に記載のものが知られている。この雌コネクタは、電線の端末に接続される複数の雌端子と、複数の雌端子を収容する合成樹脂製の雌ハウジングとを備えて構成されている。   For example, the thing of Unexamined-Japanese-Patent No. 2012-28073 (patent document 1) is known as a female connector fitted to a male connector. The female connector includes a plurality of female terminals connected to the end of the electric wire and a synthetic resin female housing that houses the plurality of female terminals.

雌ハウジングは、複数の雌端子を収容した状態で雄コネクタの嵌合筒部内に嵌合される端子収容部と、端子収容部の外周を覆った形態で嵌合筒部が内部に嵌合されるフード部とを有しており、端子収容部は、フード部の前端の位置よりも奥まった位置に配されている。端子収容部の外周面には環状のシールリングが嵌着されており、嵌合筒部と端子収容部とが嵌合すると、シールリングが嵌合筒部の内周面と端子収容部の外周面とに密着することで、複数の端子が一括して防水されている。   The female housing includes a terminal accommodating portion that is fitted in the fitting cylindrical portion of the male connector in a state in which a plurality of female terminals are accommodated, and a fitting cylindrical portion that is fitted inside in a form that covers the outer periphery of the terminal accommodating portion. The terminal housing portion is disposed at a position deeper than the position of the front end of the hood portion. An annular seal ring is fitted on the outer peripheral surface of the terminal accommodating portion, and when the fitting tube portion and the terminal accommodating portion are fitted, the seal ring is fitted to the inner peripheral surface of the fitting cylindrical portion and the outer periphery of the terminal accommodating portion. A plurality of terminals are collectively waterproofed by being in close contact with the surface.

特開２０１２−２８０７３号公報JP 2012-28073 A

ところで、嵌合筒部と端子収容部とを嵌合させる前に、例えば、端子収容部内に水などが浸入していると、嵌合筒部と端子収容部とを嵌合させた後に、嵌合部内に浸入した水によって雌端子同士が短絡してしまう虞がある。このため、雌端子を個別に収容した状態で雄コネクタに設けられた複数のキャビティにそれぞれ嵌合される複数の端子収容部を形成し、それぞれのキャビティの内周面と端子収容部との間を個別シール部材によって止水することで、雌端子同士が短絡することを防止することが検討されている。   By the way, before fitting the fitting tube portion and the terminal housing portion, for example, if water or the like has entered the terminal housing portion, the fitting tube portion and the terminal housing portion are fitted after fitting. There is a possibility that the female terminals may be short-circuited by water that has entered the joint. For this reason, a plurality of terminal accommodating portions that are respectively fitted to a plurality of cavities provided in the male connector in a state where the female terminals are individually accommodated are formed, and between the inner peripheral surface of each cavity and the terminal accommodating portion. It has been studied to prevent the female terminals from being short-circuited by stopping water with an individual seal member.

ところが、複数のキャビティに対して複数の端子収容部を嵌合させる状況において、従来のように、各端子収容部がフード部の前端の位置よりも奥まった位置に配されている場合、雄コネクタである相手側コネクタとフード部との嵌合過程において、僅かなこじりが生じるだけで相手側コネクタと端子収容部とが嵌合方向に突き当たってしまい、相手側コネクタとフード部とを嵌合させることができなくなってしまう。   However, in a situation where a plurality of terminal accommodating portions are fitted to a plurality of cavities, when each terminal accommodating portion is arranged at a position deeper than the position of the front end of the hood portion as in the prior art, the male connector In the mating process between the mating connector and the hood part, the mating connector and the terminal receiving part abut in the mating direction with only slight twisting, and the mating connector and the hood part are mated. It becomes impossible to do.

本明細書では、嵌合過程において相手側コネクタと端子収容部とが突き当たることを抑制する技術を開示する。   In this specification, the technique which suppresses that the other party connector and terminal accommodating part contact | abut in a fitting process is disclosed.

本明細書によって開示される技術は、相手側コネクタに嵌合されるコネクタであって、電線の端末に接続される端子が個別に収容され、前記相手側コネクタに設けられた複数のキャビティ内にそれぞれ嵌合される複数の端子収容部と、前記複数の端子収容部の外周を一括して覆う形態で前記相手側コネクタと嵌合するフードとを備え、前記端子収容部の嵌合方向前側の前端面と前記フードの嵌合方向前側の前端面とが面一状に揃っているところに特徴を有する。   The technology disclosed in the present specification is a connector that is fitted to a mating connector, in which terminals connected to the ends of the electric wires are individually accommodated, and in a plurality of cavities provided in the mating connector. A plurality of terminal accommodating portions that are respectively fitted, and a hood that is fitted to the mating connector in a form that collectively covers the outer periphery of the plurality of terminal accommodating portions; It is characterized in that the front end surface and the front end surface on the front side in the fitting direction of the hood are aligned.

このような構成のコネクタによると、フードによって端子収容部の外周を覆って保護することができる最前の位置に端子収容部が配置されているから、端子収容部がフードの奥側に配されている場合に比べて、キャビティ内に端子収容部を早めに嵌合させることができる。これにより、相手側コネクタとフードとの嵌合過程において、キャビティと端子収容部との芯ずれが大きくなる前にキャビティと端子収容部とを嵌合させることができ、相手側コネクタと端子収容部とが嵌合方向に突き当たることを抑制することができる。   According to the connector having such a configuration, since the terminal accommodating portion is arranged at the foremost position where the outer periphery of the terminal accommodating portion can be covered and protected by the hood, the terminal accommodating portion is arranged on the back side of the hood. Compared with the case where it exists, a terminal accommodating part can be fitted in a cavity early. Thereby, in the fitting process between the mating connector and the hood, the cavity and the terminal housing portion can be fitted before the core misalignment between the cavity and the terminal housing portion becomes large. Can be prevented from striking in the fitting direction.

また、フード内における最前の位置に端子収容部が配されているから、端子収容部がフードの前端面の位置よりも後方であるフードの奥側に配されている場合に比べて、端子収容部が前側に配されている分だけコネクタの前後方向の大きさを小型化することができる。   Also, since the terminal accommodating portion is arranged at the foremost position in the hood, the terminal accommodating portion is accommodated compared to the case where the terminal accommodating portion is arranged on the back side of the hood, which is behind the position of the front end surface of the hood. The size of the connector in the front-rear direction can be reduced by the amount of the portion disposed on the front side.

本明細書によって開示される技術の態様として、以下の構成が好ましい。
前記端子収容部の外周面には、前記キャビティの内周面と前記端子収容部の外周面との間を止水する個別シール部材が嵌着されており、前記端子収容部の前端部には、前記個別シール部材の前方への抜け止めをするキャップが前方からそれぞれ装着されている構成としてもよい。
このような構成によると、フード内における最前の位置に配される端子収容部の前端部にキャップを着脱することになるから、キャップの着脱作業が容易である。つまり、フード内の各端子収容部にキャップをそれぞれ装着する場合に非常に有効である。 As an aspect of the technology disclosed by this specification, the following configurations are preferable.
An individual seal member for stopping water between the inner peripheral surface of the cavity and the outer peripheral surface of the terminal accommodating portion is fitted to the outer peripheral surface of the terminal accommodating portion, and the front end portion of the terminal accommodating portion is fitted. The caps that prevent the individual seal members from coming forward may be mounted from the front.
According to such a configuration, since the cap is attached to and detached from the front end portion of the terminal accommodating portion disposed at the foremost position in the hood, the attachment and detachment work of the cap is easy. That is, it is very effective when the cap is attached to each terminal accommodating portion in the hood.

前記複数の端子収容部を一括して収容する形態に設けられ、前記相手側コネクタと前記フードとの間からの水の浸入を防止する環状の一括シール部材が外嵌される内フードを備え、前記端子収容部の前端部は、前記内フードから前方に突出している構成としてもよい。
このような構成によると、内フードから端子収容部の前端部が突出しているから端子収容部に対するキャップの着脱作業をさらに簡単に行うことができる。 An inner hood that is provided in a form for collectively accommodating the plurality of terminal accommodating portions, and into which an annular collective seal member that prevents water from entering between the mating connector and the hood is fitted, The front end portion of the terminal accommodating portion may protrude forward from the inner hood.
According to such a configuration, since the front end portion of the terminal accommodating portion protrudes from the inner hood, the cap can be attached / detached to / from the terminal accommodating portion more easily.

本明細書によって開示される技術によれば、嵌合過程において相手側ハウジングと端子収容部とが突き当たることを抑制することができる。   According to the technique disclosed by this specification, it can suppress that the other party housing and terminal accommodating part collide in a fitting process.

A plurality of cantilevered contact pieces 26 that can be elastically displaced are provided at the rear part of the shield shell 25, and the contact pieces 26 come into contact with the outer peripheral surface of the caulking ring 55, so that the shield shell 25 and the caulking ring 55 Are electrically connected.

シールドシェル２５の前端部は、機器側コネクタ８０の機器側シェル８８と接続可能とされており、外フード１２と機器側ハウジング８１とが嵌合すると、機器側シェル８８とシールドシェル２５の前端部とが電気的に接続されるようになっている。
電線収容部１６の後部には、図３から図８に示すように、電線収容部１６の内周面と各シールド電線５０の外周面との間を止水する一括ゴム栓２８が装着されている。一括ゴム栓２８は、複数のシールド電線５０を前後方向に挿通した状態で電線収容部１６の後端部内に嵌着されており、電線収容部１６の後端部に装着されたキャップ状のゴム栓ホルダ２９によって抜け止めされている。 The front end portion of the shield shell 25 can be connected to the device-side shell 88 of the device-side connector 80. When the outer hood 12 and the device-side housing 81 are fitted, the device-side shell 88 and the front end portion of the shield shell 25 are connected. Are electrically connected to each other.
As shown in FIG. 3 to FIG. 8, a collective rubber plug 28 that stops water between the inner peripheral surface of the electric wire storage portion 16 and the outer peripheral surface of each shielded electric wire 50 is attached to the rear portion of the electric wire storage portion 16. Yes. The collective rubber plug 28 is fitted into the rear end portion of the wire housing portion 16 in a state where the plurality of shielded wires 50 are inserted in the front-rear direction, and is a cap-like rubber attached to the rear end portion of the wire housing portion 16. The stopper holder 29 prevents it from coming off.

外フード１２は前方に向かって開口しており、外フード１２の上部には、図１および図２に示すように、機器側コネクタ８０の上部に設けられた図示しないロック部と係止するロックアーム１４が設けられている。このロックアーム１４は、外フード１２と機器側ハウジング８１とが正規の嵌合状態に至ると、ロック部と係止し、機器側コネクタ８０とコネクタ１０とを嵌合状態に保持するようになっている。   The outer hood 12 is open toward the front, and an upper portion of the outer hood 12 is locked to a lock portion (not shown) provided at the upper portion of the device-side connector 80 as shown in FIGS. An arm 14 is provided. When the outer hood 12 and the device-side housing 81 reach a proper fitted state, the lock arm 14 is engaged with the lock portion and holds the device-side connector 80 and the connector 10 in the fitted state. ing.

さて、各端子収容部２１は、内フード１５から前方に向けて突出し、端子収容部２１の前端面２１Ａが外フード１２の前端面１２Ｂと面一状に揃う位置まで突出した形態とされている。したがって、端子収容部２１の前端部は、内フード１５から露出しており、端子収容部２１に装着されたフロントキャップ２４のほぼ全体が内フード１５から露出した状態となっている。
つまり、外フード１２によって端子収容部２１の外周を覆って保護することができる最前の位置に端子収容部２１が配置され、その端子収容部２１に装着されるフロントキャップ２４が内フード１５から露出した状態となっている。
また、端子収容部２１が外フード１２内の最前の位置に配され、コネクタ１０において雌端子４０が前寄りの位置に配されているから、雌端子４０からかしめリング５５までの部分が従来のコネクタに比べて前方にスライドした形態になっている。 Now, each terminal accommodating portion 21 protrudes forward from the inner hood 15 and protrudes to a position where the front end surface 21A of the terminal accommodating portion 21 is flush with the front end surface 12B of the outer hood 12. . Therefore, the front end portion of the terminal accommodating portion 21 is exposed from the inner hood 15, and almost the entire front cap 24 attached to the terminal accommodating portion 21 is exposed from the inner hood 15.
That is, the terminal accommodating portion 21 is disposed at the foremost position where the outer hood 12 can cover and protect the outer periphery of the terminal accommodating portion 21, and the front cap 24 attached to the terminal accommodating portion 21 is exposed from the inner hood 15. It has become a state.
Moreover, since the terminal accommodating part 21 is distribute | arranged to the foremost position in the outer hood 12, and the female terminal 40 is distribute | arranged to the front position in the connector 10, the part from the female terminal 40 to the crimping ring 55 is conventional. Compared to the connector, it slides forward.

本実施形態は、以上のような構成であって、続いて、コネクタ１０の作用および効果について説明する。
コネクタ１０と機器側コネクタ８０とを嵌合させる際には、図３および図５に示すように、両コネクタ１０，８０とを向かい合わせに配置し、ハウジング１１における外フード１２と内フード１５との間に機器側ハウジング８１の機器側フード８２を挿入するように両コネクタ１０，８０とを互いに近づけて嵌合させる。 The present embodiment is configured as described above. Next, the operation and effect of the connector 10 will be described.
When the connector 10 and the device-side connector 80 are fitted, as shown in FIGS. 3 and 5, both the connectors 10 and 80 are disposed facing each other, and the outer hood 12 and the inner hood 15 in the housing 11 The connectors 10 and 80 are fitted close to each other so that the device-side hood 82 of the device-side housing 81 is inserted between them.

ところで、複数の機器側キャビティ８４に対して複数の端子収容部２１をそれぞれ嵌合させる状況おいて、例えば、端子収容部が外フードの前端面よりも奥まった位置に配置されている場合、両コネクタ間で僅かなこじりが生じただけで、複数の機器側キャビティと複数の端子収容部との間の何れかで芯ずれが生じてしまい、筒部と端子収容部とが嵌合方向に突き当たることで、機器側ハウジングと外フードとを嵌合させることができなくなってしまう。   By the way, in the situation where the plurality of terminal accommodating portions 21 are respectively fitted to the plurality of device side cavities 84, for example, when the terminal accommodating portion is disposed at a position deeper than the front end surface of the outer hood, both A slight twist between the connectors causes a misalignment between any of the plurality of device side cavities and the plurality of terminal accommodating portions, and the cylindrical portion and the terminal accommodating portion abut against each other in the fitting direction. As a result, the device-side housing and the outer hood cannot be fitted.

ところが、本実施形態によると、各端子収容部２１は、その前端面２１Ａが外フード１２の前端面１２Ｂと面一状に揃う位置まで突出した形態とされているから、図４および図７に示すように、外フード１２内に機器側フード８２を嵌合させるタイミングとほぼ同じタイミングで、機器側ハウジング８１の機器側キャビティ８４内に端子収容部２１を嵌合させることができる。
つまり、外フード１２内に機器側フード８２を嵌合させる過程において、機器側キャビティ８４と端子収容部２１との芯ずれが大きくなる前に、機器側キャビティ８４内に端子収容部２１を嵌合させることができるから、筒部８３と端子収容部２１とが嵌合方向である前後方向に突き当たることを抑制し、機器側コネクタ８０とコネクタ１０とを円滑に嵌合させることができる。 However, according to the present embodiment, each terminal accommodating portion 21 has a configuration in which the front end surface 21A protrudes to a position where the front end surface 12B is flush with the front end surface 12B of the outer hood 12. As shown, the terminal accommodating portion 21 can be fitted into the device-side cavity 84 of the device-side housing 81 at substantially the same timing as when the device-side hood 82 is fitted into the outer hood 12.
That is, in the process of fitting the device side hood 82 into the outer hood 12, the terminal housing portion 21 is fitted into the device side cavity 84 before the misalignment between the device side cavity 84 and the terminal housing portion 21 becomes large. Therefore, it can suppress that the cylinder part 83 and the terminal accommodating part 21 contact | abut in the front-back direction which is a fitting direction, and can make the apparatus side connector 80 and the connector 10 fit smoothly.

以上ように、本実施形態によると、端子収容部２１の嵌合方向前側の前端面２１Ａと外フード１２の嵌合方向前側の前端面１２Ｂとが面一状に揃うように各端子収容部２１を外フード１２内に配置して、外フード１２内に機器側フード８２を嵌合させるタイミングとほぼ同じタイミングで、機器側ハウジング８１の機器側キャビティ８４内に端子収容部２１を嵌合させるようにしたから、筒部８３と端子収容部２１とを前後方向に突き当てさせることなく、機器側コネクタ８０とコネクタ１０とを円滑に嵌合させることができる。   As described above, according to the present embodiment, each terminal accommodating portion 21 is arranged so that the front end surface 21A on the front side in the fitting direction of the terminal accommodating portion 21 and the front end surface 12B on the front side in the fitting direction of the outer hood 12 are aligned. Is arranged in the outer hood 12 so that the terminal accommodating portion 21 is fitted in the device-side cavity 84 of the device-side housing 81 at substantially the same timing as when the device-side hood 82 is fitted in the outer hood 12. Therefore, the apparatus-side connector 80 and the connector 10 can be smoothly fitted without causing the cylindrical portion 83 and the terminal accommodating portion 21 to abut in the front-rear direction.

また、本実施形態によると、外フード１２によって端子収容部２１の外周を保護できる最前の位置に端子収容部２１を配しているから、例えば、端子収容部が外フードの前端面の位置よりも奥まった位置に配される場合に比べて、端子収容部２１が前方に配されている分だけコネクタ１０の前後方向の大きさを小型化することができる。   Moreover, according to this embodiment, since the terminal accommodating part 21 is distribute | arranged to the foremost position which can protect the outer periphery of the terminal accommodating part 21 with the outer hood 12, for example, a terminal accommodating part is rather than the position of the front end surface of an outer hood. As compared with the case where the terminal housing portion 21 is disposed in the front, the size of the connector 10 in the front-rear direction can be reduced by the amount disposed forward.

また、本実施形態によると、各雌端子４０を個別に防水する個別シールリング２３の抜け止めを図るフロントキャップ２４を各端子収容部２１に対してそれぞれ装着する必要がある。このような場合、本実施形態によると、端子収容部２１が外フード１２内における最前の位置に配されているから、例えば、端子収容部が外フードの前端面の位置よりも奥まった位置に配される場合に比べて、外フード１２内の各端子収容部２１にフロントキャップ２４を着脱する作業が容易であり、非常に有効である。
さらに、本実施形態によると、端子収容部２１の前端部が、内フード１５から前方に突出し、フロントキャップ２４のほぼ全体が内フード１５から露出した状態となっているから、端子収容部２１に対するフロントキャップ２４の着脱をさらに簡単に行うことができる。 In addition, according to the present embodiment, it is necessary to attach the front caps 24 for preventing the individual seal rings 23 that individually waterproof the respective female terminals 40 to the terminal accommodating portions 21. In such a case, according to the present embodiment, since the terminal accommodating portion 21 is arranged at the foremost position in the outer hood 12, for example, the terminal accommodating portion is located deeper than the position of the front end surface of the outer hood. Compared with the case where it is arranged, the work of attaching and detaching the front cap 24 to each terminal accommodating portion 21 in the outer hood 12 is easy and very effective.
Furthermore, according to the present embodiment, the front end portion of the terminal accommodating portion 21 protrudes forward from the inner hood 15, and almost the entire front cap 24 is exposed from the inner hood 15. The front cap 24 can be attached and detached more easily.
