Description

本発明は、防水コネクタに関し、特に、雌コネクタの雌ハウジングにハウジングシールが装着された防水コネクタに関する。   The present invention relates to a waterproof connector, and more particularly to a waterproof connector in which a housing seal is mounted on a female housing of a female connector.

一般に、防水コネクタは、例えば自動車のエンジンルームなどの防水を要する箇所で電気的接続を行うために用いられている。   In general, the waterproof connector is used for electrical connection at a location requiring waterproofing such as an engine room of an automobile, for example.

図６は、従来の防水コネクタを示す側面断面図であり、（Ａ）は防水コネクタの嵌合前の状態、（Ｂ）は嵌合終了後の状態を示し、図７（Ａ）は雄ハウジングの嵌合開口側を示す正面図、（Ｂ）は雌ハウジングの嵌合開口側を示す正面図である。   6A and 6B are side sectional views showing a conventional waterproof connector, in which FIG. 6A shows a state before fitting the waterproof connector, FIG. 6B shows a state after completion of fitting, and FIG. The front view which shows the fitting opening side of this, (B) is a front view which shows the fitting opening side of a female housing.

従来の防水コネクタ５０は、互いに嵌合可能な雄コネクタ１と雌コネクタ２とを有する。   A conventional waterproof connector 50 includes a male connector 1 and a female connector 2 that can be fitted to each other.

雄コネクタ１は、合成樹脂などで作られた雄ハウジング３と、雄ハウジング３に保持される雄端子金具４とを有する。雌コネクタ２は、合成樹脂などで作られた雌ハウジング５と、雌ハウジング５に収容される雌端子金具６とを有する。   The male connector 1 includes a male housing 3 made of synthetic resin or the like and a male terminal fitting 4 held by the male housing 3. The female connector 2 has a female housing 5 made of a synthetic resin or the like and a female terminal fitting 6 accommodated in the female housing 5.

雄ハウジング３の先端部には、雌ハウジング５に嵌合可能な筒状のフード部７を備えている。フード部７の先端側外周部には、雌ハウジング５に形成されたロック孔８に係止されるロック部９が外側に突出して設けられている。   A cylindrical hood portion 7 that can be fitted to the female housing 5 is provided at the distal end portion of the male housing 3. A lock portion 9 that is engaged with a lock hole 8 formed in the female housing 5 is provided on the outer peripheral portion on the front end side of the hood portion 7 so as to protrude outward.

雄端子金具４は、フード部７の内側において雄ハウジング３の基端面３ａから突出して保持されている。   The male terminal fitting 4 protrudes from the base end surface 3 a of the male housing 3 and is held inside the hood portion 7.

一方、雌ハウジング５は、内筒部１０と、その内筒部１０に連結され、内筒部１０の外周を囲う外筒部１１と、内筒部１０に連結され、端子挿入孔２１ａが形成されたリテーナ２１とを有する。   On the other hand, the female housing 5 is connected to the inner cylinder part 10, the inner cylinder part 10, the outer cylinder part 11 surrounding the outer periphery of the inner cylinder part 10, and the inner cylinder part 10 to form a terminal insertion hole 21a. The retainer 21 is provided.

内筒部１０には、雌端子金具６を基端側（図６では右側）から挿入可能な複数（図６では３室）のキャビティ１２が配置されている。雌端子金具６は、雄端子金具４と接続される接続部６ａと、電線Ｗの先端から露出された芯線にかしめなどにより圧着固定される電線固定部６ｂとを有する。電線固定部６ｂの後端には、電線Ｗの被覆部に嵌着された防水用ゴム栓１３が取り付けられている。防水用ゴム栓１３は、キャビティ１２の内周面に密着することにより、キャビティ１２内をシールする。   A plurality of (three chambers in FIG. 6) cavities 12 into which the female terminal fitting 6 can be inserted from the base end side (right side in FIG. 6) are disposed in the inner cylinder portion 10. The female terminal fitting 6 has a connecting portion 6a connected to the male terminal fitting 4 and an electric wire fixing portion 6b that is crimped and fixed to the core wire exposed from the tip of the electric wire W by caulking or the like. At the rear end of the wire fixing portion 6b, a waterproof rubber plug 13 fitted to the covering portion of the wire W is attached. The waterproof rubber plug 13 seals the inside of the cavity 12 by being in close contact with the inner peripheral surface of the cavity 12.

キャビティ１２の内部には、雌端子金具６を係止するためのランス１４が突設されている。ランス１４は、キャビティ１２内に雌端子金具６が挿入される途中では接続部６ａにより押圧されることで弾性変形し、雌端子金具６が所定の位置まで挿入されると、弾性復帰して、接続部６ａに形成された係止孔６ｃ内に入り、雌端子金具６を係止する。   A lance 14 for locking the female terminal fitting 6 projects from the cavity 12. The lance 14 is elastically deformed by being pressed by the connecting portion 6a while the female terminal fitting 6 is being inserted into the cavity 12, and when the female terminal fitting 6 is inserted to a predetermined position, the lance 14 is elastically restored, It enters into the locking hole 6c formed in the connecting portion 6a and locks the female terminal fitting 6.

外筒部１１の内周面と内筒部１０及びリテーナ２１の外周面との間には、雄コネクタ１のフード部７が挿入され、嵌合される嵌合穴１５が形成されている。   A fitting hole 15 into which the hood portion 7 of the male connector 1 is inserted and fitted is formed between the inner peripheral surface of the outer cylindrical portion 11 and the outer peripheral surfaces of the inner cylindrical portion 10 and the retainer 21.

嵌合穴１５の基端部より先端部側における内筒部１０の外周面には段差部１７が形成され、その段差部１７の係止端面１７ａに係止されるように、ゴムリングなどで作られたハウジングシール１６が嵌着されている。   A stepped portion 17 is formed on the outer peripheral surface of the inner cylinder portion 10 on the distal end side from the base end portion of the fitting hole 15, and is locked with a locking end surface 17 a of the stepped portion 17 with a rubber ring or the like. A made housing seal 16 is fitted.

ハウジングシール１６が基端部より先端部側に装着されているのは、雄端子金具４が雌端子金具６に挿入され嵌合される際に発生する端子嵌合力のピークと、フード部７の先端がハウジングシール１６を乗り越える際に発生するシール嵌合力のピークを分散させるためである。   The housing seal 16 is attached to the distal end side from the base end portion because the terminal fitting force peak generated when the male terminal fitting 4 is inserted and fitted into the female terminal fitting 6 and the hood portion 7 This is to disperse the peak of the seal fitting force that occurs when the tip gets over the housing seal 16.

外筒部１１の外周面には、雄コネクタ１のロック部９が係止されるロック孔８が形成されている。   On the outer peripheral surface of the outer cylinder portion 11, a lock hole 8 is formed in which the lock portion 9 of the male connector 1 is locked.

次に、雄コネクタ１と雌コネクタ２との嵌合作業の手順について説明する。   Next, a procedure for fitting work between the male connector 1 and the female connector 2 will be described.

まず、雌ハウジング５の嵌合穴１５に雄ハウジング３のフード部７を挿入する。その際、フード部７の先端部が雌ハウジング５のハウジングシール１６に当接する。フード部７に当接されたハウジングシール１６は弾性変形するので、フード部７の進入は可能となる。   First, the hood portion 7 of the male housing 3 is inserted into the fitting hole 15 of the female housing 5. At that time, the distal end portion of the hood portion 7 comes into contact with the housing seal 16 of the female housing 5. Since the housing seal 16 in contact with the hood portion 7 is elastically deformed, the hood portion 7 can enter.

フード部７をさらに進入させ、フード部７の先端部が嵌合穴１５の基端部に当接すると同時に、フード部７のロック部９が雌ハウジング５に形成されたロック孔８に係止される。その際、雄端子金具４と雌端子金具６とが接続される。ハウジングシール１６は、フード部７の内周面と雌ハウジング５の内筒部１０の外周面の間に挟まれる形で防水する（図６（Ｂ）参照）。これによって、雄コネクタ１と雌コネクタ２との嵌合作業が完了する（以下、この技術を従来例１という）。   The hood portion 7 is further advanced, and the distal end portion of the hood portion 7 comes into contact with the proximal end portion of the fitting hole 15, and at the same time, the lock portion 9 of the hood portion 7 is locked in the lock hole 8 formed in the female housing 5. Is done. At that time, the male terminal fitting 4 and the female terminal fitting 6 are connected. The housing seal 16 is waterproofed by being sandwiched between the inner peripheral surface of the hood portion 7 and the outer peripheral surface of the inner cylinder portion 10 of the female housing 5 (see FIG. 6B). Thereby, the fitting operation between the male connector 1 and the female connector 2 is completed (hereinafter, this technique is referred to as Conventional Example 1).

また、特許文献１では、ハウジング同士の嵌合時におけるゴムリング嵌合方向へのズレを防止する防水コネクタが開示されている。この防水コネクタでは、雌ハウジングに形成された受け面が、雌ハウジングの外周面（雄ハウジングと雌ハウジングの嵌合方向）に対してこの外周面側に倒れるように傾斜し、ゴムリングの端面はこの受け面と同じ方向に傾斜している。雄ハウジングにより嵌合方向に押されたゴムリングの先端部は、受け面に押し付けられてその傾斜により外周面側への誘導力を受ける。これによって、ゴムリングがその先端部を外周面から外側へ逃がすように弾性変形させつつ嵌合方向に移動する、ことを防止する（以下、この技術を従来例２という）。
特開平８−２８８００３号公報 Further, Patent Document 1 discloses a waterproof connector that prevents displacement in a rubber ring fitting direction at the time of fitting between housings. In this waterproof connector, the receiving surface formed on the female housing is inclined so as to fall toward the outer peripheral surface side with respect to the outer peripheral surface of the female housing (the fitting direction of the male housing and the female housing), and the end surface of the rubber ring is It is inclined in the same direction as this receiving surface. The tip of the rubber ring pressed in the fitting direction by the male housing is pressed against the receiving surface and receives an induction force toward the outer peripheral surface due to the inclination. This prevents the rubber ring from moving in the fitting direction while being elastically deformed so as to allow the tip portion to escape from the outer peripheral surface (hereinafter, this technique is referred to as Conventional Example 2).
JP-A-8-288003

従来例１では、ハウジングシール１６は、そのシール性を向上させるために、内筒部１０の外周に形成された段差部１７の係止端面１７ａの高さよりも高く形成されている。しかし、雄コネクタ１をこじりながら嵌合させると、図６（Ｃ）に示すように、本来フード部７が収容されるべきスペースにハウジングシール１６が脱落してズレてしまい、シール性が著しく低下する場合があるという課題があった。   In Conventional Example 1, the housing seal 16 is formed higher than the height of the locking end surface 17a of the stepped portion 17 formed on the outer periphery of the inner cylinder portion 10 in order to improve the sealing performance. However, if the male connector 1 is squeezed and fitted, as shown in FIG. 6 (C), the housing seal 16 is dropped and displaced in the space where the hood portion 7 should be originally housed, and the sealing performance is significantly reduced. There was a problem that there was a case.

また、ハウジングシール１６の高さを低くするか、係止端面１７ａの高さを高くすれば、ハウジング１６のズレを防止できるが、この場合にはハウジングシール１６の圧縮率が低下するため、シール性が低下するという課題があった。   Further, if the height of the housing seal 16 is lowered or the height of the locking end surface 17a is raised, the housing 16 can be prevented from being displaced. In this case, however, the compression rate of the housing seal 16 is reduced, so that the seal There was a problem that the performance was lowered.

従来例２では、雌ハウジングに形成された受け面が傾斜していることにより、ゴムリングのズレを防止する構造になっているが、受け面の高さはゴムリングの高さよりも低いので、ゴムリングのズレを完全に防止することは困難であるという課題があった。   In Conventional Example 2, the receiving surface formed on the female housing is inclined to prevent the rubber ring from shifting, but the height of the receiving surface is lower than the height of the rubber ring. There was a problem that it was difficult to completely prevent the rubber ring from being displaced.

本発明は、上記課題を解決するためになされたものであり、ハウジングシールのシール性を維持しながら、ハウジングシールのズレを防止することができる防水コネクタを提供することを目的とする。   The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a waterproof connector that can prevent the housing seal from shifting while maintaining the sealing performance of the housing seal.

本発明の防水コネクタは、筒状のフード部を備えた雄ハウジングと、その雄ハウジングに保持される雄端子金具とを有する雄コネクタと、
前記フード部が挿入され嵌合される嵌合穴を備えた雌ハウジングと、その雌ハウジングに保持され、前記雄端子金具が挿入され嵌合される雌端子金具とを有する雌コネクタと、からなり、
前記雌ハウジングの嵌合穴内部に段差部が形成され、その段差部の係止端面に係止された状態でハウジングシールが嵌着された防水コネクタにおいて、
前記段差部の外周面には、前記ハウジングシールの高さよりも高く形成された複数のリブが間隔を隔てて設けられ、
前記フード部の先端側内周面には、前記各リブが挿入される逃し部が間隔を隔てて形成されている、ことを特徴とするものである。 The waterproof connector of the present invention is a male connector having a male housing having a cylindrical hood portion, and a male terminal fitting held by the male housing,
A female housing having a fitting hole into which the hood portion is inserted and fitted, and a female connector held in the female housing and having a female terminal fitting into which the male terminal fitting is inserted and fitted. ,
In the waterproof connector in which the step portion is formed inside the fitting hole of the female housing and the housing seal is fitted in a state of being locked to the locking end surface of the step portion,
On the outer peripheral surface of the stepped portion, a plurality of ribs formed higher than the height of the housing seal are provided at intervals.
A relief portion into which the ribs are inserted is formed on the inner peripheral surface of the distal end side of the hood portion with a gap therebetween.

前記リブの前記ハウジングシール側に向いた面は、嵌合方向とのなす角度が９０度より小さい角度で傾斜して形成されていてもよい。   The surface of the rib facing the housing seal side may be formed to be inclined at an angle smaller than 90 degrees with the fitting direction.

本発明の防水コネクタによれば、雌ハウジングの嵌合穴の内部に形成された段差部の外周面に、ハウジングシールの高さよりも高く形成された複数のリブが間隔を隔てて設けられているので、リブによってハウジングシールの脱落、座屈、捲れなどの発生が規制され、コネクタ嵌合時にハウジングシールの嵌合方向に対するズレを防止することができる。   According to the waterproof connector of the present invention, the plurality of ribs formed higher than the height of the housing seal are provided at intervals on the outer peripheral surface of the step portion formed inside the fitting hole of the female housing. Therefore, the ribs restrict the occurrence of the housing seal from dropping, buckling, squeezing, and the like, and can prevent the housing seal from being displaced in the fitting direction when the connector is fitted.

また、雄コネクタのフード部の先端側内周面には、各リブが挿入される逃し部が間隔を隔てて形成されているので、ハウジングシールよりも高いリブを設けても、フード部の進入が可能となり、ハウジングシールの圧縮率が低下することはなく、シール性は維持される。   In addition, since the relief portion into which each rib is inserted is formed on the inner peripheral surface of the distal end side of the hood portion of the male connector at an interval, the hood portion can enter even if a rib higher than the housing seal is provided. Therefore, the compressibility of the housing seal is not lowered, and the sealing performance is maintained.

以下、本発明の実施の形態について図面を参照して説明する。なお、従来例１と同一の部材は同一の符号を付して適宜説明を省略する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the same members as those of the conventional example 1 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

図１及び図２は、本発明の実施形態例に係る防水コネクタを示す側面断面図であり、図１（Ａ）は嵌合前の状態で、雌ハウジングのリブがない箇所を断面で示し、図１（Ｂ）は雌ハウジングのリブがある箇所を断面で示し、図２（Ａ）はシール嵌合力がピークの状態を示し、図２（Ｂ）はコネクタ嵌合が終了した状態を示す。図３（Ａ）は雄ハウジングの嵌合開口側を示す正面図、（Ｂ）は雌ハウジングの嵌合開口側を示す正面図である。
図１、図２及び図３（Ｂ）に示すように、本発明の実施形態例に係る防水コネクタ２０は、雌ハウジング５の嵌合穴１５の内部に形成された段差部１７の外周面１７ｂに、ハウジングシール１６の高さよりも高く形成された複数のリブ１８が間隔を隔てて設けられている。 1 and 2 are side cross-sectional views showing a waterproof connector according to an embodiment of the present invention, and FIG. 1 (A) is a state before fitting, showing a section without a rib of a female housing, FIG. 1B shows a section of the female housing where the rib is located, FIG. 2A shows a state where the seal fitting force is at a peak, and FIG. 2B shows a state where the connector fitting is finished. FIG. 3A is a front view showing the fitting opening side of the male housing, and FIG. 3B is a front view showing the fitting opening side of the female housing.
As shown in FIGS. 1, 2, and 3 (B), the waterproof connector 20 according to the embodiment of the present invention includes an outer peripheral surface 17 b of a stepped portion 17 formed inside the fitting hole 15 of the female housing 5. In addition, a plurality of ribs 18 formed higher than the height of the housing seal 16 are provided at intervals.

一方、図１、図２及び図３（Ａ）に示すように、雄コネクタ１のフード部７の先端側内周面には、各リブ１８が挿入される複数の逃し部１９が間隔を隔てて形成されている。逃し部１９は、方形の溝に形成されている。   On the other hand, as shown in FIGS. 1, 2, and 3 (A), a plurality of relief portions 19 into which the ribs 18 are inserted are spaced from each other on the inner peripheral surface of the distal end side of the hood portion 7 of the male connector 1. Is formed. The relief portion 19 is formed in a square groove.

次に、雄コネクタ１と雌コネクタ２との嵌合作業の手順について説明する。   Next, a procedure for fitting work between the male connector 1 and the female connector 2 will be described.

まず、雌ハウジング５の嵌合穴１５に雄ハウジング３のフード部７を挿入する。その際、図２（Ａ）に示すように、フード部７の先端部がハウジングシール１６に当接する。フード部７に当接されたハウジングシール１６は弾性変形し、フード部７の先端がハウジングシール１６を乗り越える際に発生するシール嵌合力がピークに達する。この時点で、雄端子金具４は雌端子金具６に挿入される。   First, the hood portion 7 of the male housing 3 is inserted into the fitting hole 15 of the female housing 5. At that time, as shown in FIG. 2A, the front end portion of the hood portion 7 contacts the housing seal 16. The housing seal 16 in contact with the hood portion 7 is elastically deformed, and the seal fitting force generated when the tip of the hood portion 7 gets over the housing seal 16 reaches a peak. At this point, the male terminal fitting 4 is inserted into the female terminal fitting 6.

次いで、フード部７をさらに進入させると、フード部７の逃し部１８に雌ハウジング４のリブ１８が挿入される。   Next, when the hood portion 7 is further advanced, the rib 18 of the female housing 4 is inserted into the relief portion 18 of the hood portion 7.

その後、フード部７の先端部が嵌合穴１５の基端部に当接すると同時に、フード部７のロック部９が雌ハウジング５に形成されたロック孔８に係止される。その際、雄端子金具４が雌端子金具６に嵌合され接続される（図２（Ｂ）参照）。これによって、雄コネクタ１と雌コネクタ２との嵌合作業が完了する。   Thereafter, the distal end portion of the hood portion 7 comes into contact with the proximal end portion of the fitting hole 15, and at the same time, the lock portion 9 of the hood portion 7 is engaged with the lock hole 8 formed in the female housing 5. At that time, the male terminal fitting 4 is fitted and connected to the female terminal fitting 6 (see FIG. 2B). Thereby, the fitting operation between the male connector 1 and the female connector 2 is completed.

本発明の実施形態例に係る防水コネクタ２０によれば、雌ハウジング５の嵌合穴１５の内部に形成された段差部１７の外周面１７ｂに、ハウジングシール１６の高さよりも高く形成された複数のリブ１８が間隔を隔てて設けられているので、リブ１８によってハウジングシール１６の脱落、座屈、捲れなどの発生が規制され、コネクタ嵌合時にハウジングシール１６の嵌合方向に対するズレを防止することができる。   According to the waterproof connector 20 according to the embodiment of the present invention, a plurality of the outer peripheral surface 17b of the stepped portion 17 formed inside the fitting hole 15 of the female housing 5 are formed higher than the height of the housing seal 16. Since the ribs 18 are provided at intervals, the ribs 18 prevent the housing seal 16 from dropping, buckling, squeezing, etc., and prevent the housing seal 16 from being displaced in the fitting direction when the connector is fitted. be able to.

また、雄コネクタ１のフード部７の先端側内周面には、各リブ１８が挿入される複数の逃し部１９が間隔を隔てて形成されているので、ハウジングシール１６よりも高いリブ１８を設けても、フード部７の進入が可能となり、ハウジングシール１６の圧縮率が低下することはなく、シール性は維持される。   Further, since a plurality of relief portions 19 into which the ribs 18 are inserted are formed at intervals on the inner peripheral surface of the front end of the hood portion 7 of the male connector 1, the ribs 18 higher than the housing seal 16 are provided. Even if provided, the hood portion 7 can enter, the compression rate of the housing seal 16 does not decrease, and the sealing performance is maintained.

図４は、リブの変形例を示す側面断面図である。図４に示すように、リブ１８のハウジングシール１６側に向いた面１８ａは、嵌合方向とのなす角度が９０度より小さい角度θで傾斜して形成されていてもよい。これによって、ハウジングシール１６の脱落、座屈、捲れの発生がさらに規制されるので、コネクタ嵌合時にハウジングシール１６の嵌合方向に対するズレをより確実に防止することができる。   FIG. 4 is a side sectional view showing a modification of the rib. As shown in FIG. 4, the surface 18a of the rib 18 facing the housing seal 16 may be formed so as to be inclined at an angle θ smaller than 90 degrees with the fitting direction. As a result, the housing seal 16 is further prevented from dropping, buckling, and wobbling, so that the housing seal 16 can be more reliably prevented from being displaced in the fitting direction when the connector is fitted.

図５（Ａ）は逃し部の変形例を示す平面図、（Ｂ）は逃し部の他の変形例を示す正面図である。逃し部１９は、図５（Ａ）に示すように、切り欠き状に形成されてもよく、図５（Ｂ）に示すように、連通した穴に形成されてもよい。   FIG. 5A is a plan view showing a modified example of the escape portion, and FIG. 5B is a front view showing another modified example of the escape portion. The relief portion 19 may be formed in a cutout shape as shown in FIG. 5 (A), or may be formed in a communicating hole as shown in FIG. 5 (B).
