Description

本発明は、コネクタの防水構造に関する。   The present invention relates to a waterproof structure for a connector.

従来、自動車等には、電線間を接続する防水コネクタが搭載されている。この種の防水コネクタは、雌端子を収容するキャビティが形成された筒状の雌ハウジングの内部に、雄端子を収容するキャビティが形成された筒状の雄ハウジングを嵌合させて用いられる。この場合、雄ハウジングの外周面に装着した環状の防水ゴムを雌ハウジングの内周面に密着させることで、互いに対向するハウジングのキャビティの開口端同士の隙間を水封するようになっている（例えば、特許文献１参照。）。   Conventionally, waterproof connectors for connecting electric wires are mounted on automobiles and the like. This type of waterproof connector is used by fitting a cylindrical male housing in which a cavity for receiving male terminals is formed into a cylindrical female housing in which a cavity for receiving female terminals is formed. In this case, the annular waterproof rubber mounted on the outer peripheral surface of the male housing is brought into close contact with the inner peripheral surface of the female housing, thereby sealing the gap between the opening ends of the housing cavities facing each other ( For example, see Patent Document 1.)

特開２０１３−５１０７１号公報JP 2013-51071 A

しかしながら、この種のコネクタは、長期間の使用によって防水ゴムが経時劣化して防水性が低下するおそれがある。また、夏場などの高温条件下では、熱膨張した防水ゴムがハウジング同士の隙間から飛び出すことがあり、このような防水ゴムに洗浄用の高圧水が噴き付けられると、防水ゴムがめくれ上がり、内部の防水ゴムが損傷して防水性の低下を招くおそれがある。   However, with this type of connector, the waterproof rubber may deteriorate with time due to long-term use, and the waterproof property may be reduced. Also, under high-temperature conditions such as in summer, the thermally expanded waterproof rubber may jump out of the gaps between the housings. When high-pressure water for cleaning is sprayed onto such waterproof rubber, the waterproof rubber is turned up and the inside The waterproof rubber may be damaged, resulting in a decrease in waterproofness.

また、上述の防水コネクタは、外気温との温度差等に起因してキャビティ内が負圧になることがある。このような場合に、防水ゴムが経時劣化や損傷等していると、コネクタの外部からキャビティの内部に水が浸入するおそれがある。   Moreover, the above-mentioned waterproof connector may have a negative pressure in the cavity due to a temperature difference from the outside air temperature or the like. In such a case, if the waterproof rubber is deteriorated or damaged with time, water may enter the cavity from the outside of the connector.

本発明は、このような問題に鑑みてなされたものであり、キャビティ内部が負圧になっても内部に水が浸入するのを防止することを課題とする。   This invention is made | formed in view of such a problem, and makes it a subject to prevent water permeating into an inside even if the inside of a cavity becomes a negative pressure.

上記課題を解決するため、本発明のコネクタの防水構造は、互いに係合する一対のハウジングにそれぞれ互いに接続される端子を収容するキャビティが形成され、このキャビティの対向する開口端同士の隙間を水封するコネクタの防水構造において、一対のキャビティの開口端部は、互いに当接する一対の樹脂製の環状部を備えて形成され、一方の環状部は、キャビティの内部の負圧により撓み変形して他方の環状部を押圧する形状に形成されてなることを特徴とする。   In order to solve the above-described problems, the waterproof structure of the connector according to the present invention includes a pair of housings that are engaged with each other, each having a cavity that accommodates a terminal that is connected to each other, and a gap between the opposing open ends of the cavity. In the waterproof structure of the connector to be sealed, the opening end portions of the pair of cavities are formed with a pair of resin annular portions that are in contact with each other, and one of the annular portions is bent and deformed by the negative pressure inside the cavity. It is formed in the shape which presses the other annular part.

これによれば、一対のキャビティの開口端部は、一対の樹脂製の環状部同士が互いに当接して一対のキャビティ内部を水封することができる。そのため、水封用の防水ゴムが不要になり、防水ゴムの経時劣化や破損等に起因する防水性の低下を防ぐことができる。特に、一方の環状部は、キャビティ内が負圧になると、撓み変形して他方の環状部を押圧するように形成され、一対の環状部同士がより強く当接するので、負圧のキャビティ内に水が浸入するのを防ぐことができる。   According to this, the opening end portions of the pair of cavities can seal the inside of the pair of cavities with the pair of resin annular portions abutting each other. This eliminates the need for water-sealing waterproof rubber, and can prevent deterioration of waterproof property due to deterioration or damage of the waterproof rubber over time. In particular, one annular part is formed so as to bend and deform to press the other annular part when the inside of the cavity becomes negative pressure, and the pair of annular parts abut more strongly, so that the negative pressure inside the cavity Water can be prevented from entering.

具体的に、一方の環状部は、他方の環状部に向かって末広がりとなる傘型に形成され、他方の環状部の開口端の周縁に内周面が当接するように構成してもよい。この場合、他方の環状部は、一方の環状部よりも高い剛性を有して形成されることが好ましく、例えば、一方の環状部と対向する筒状のハウジングの開口端部を他方の環状部としてもよい。   Specifically, one annular portion may be formed in an umbrella shape that expands toward the other annular portion, and the inner peripheral surface may be in contact with the peripheral edge of the opening end of the other annular portion. In this case, the other annular part is preferably formed with higher rigidity than the one annular part. For example, the opening end of the cylindrical housing facing the one annular part is used as the other annular part. It is good.

また、一方の環状部は、他方の環状部に向かって先窄みとなる傘型に形成され、先端から奥に向かって末広がりとなる他方の環状部の外周面に先端部が当接するように構成してもよい。この場合も、他方の環状部は、一方の環状部よりも高い剛性を有して形成されることが好ましく、例えば、一方の環状部と対向する筒状のハウジングの開口端部を他方の環状部としてもよい。   Also, one annular portion is formed in an umbrella shape that is tapered toward the other annular portion so that the distal end abuts on the outer peripheral surface of the other annular portion that widens toward the back from the distal end. It may be configured. Also in this case, the other annular portion is preferably formed with higher rigidity than the one annular portion. For example, the opening end portion of the cylindrical housing facing the one annular portion is used as the other annular portion. It is good also as a part.

また、一対の環状部は、それぞれ相手側に向かって末広がりの傘型に形成して構成してもよい。この場合、例えば、他方の環状部は、一方の環状部よりも高い剛性を有して形成され、一方の環状部の先端部が他方の環状部の内周面に当接するように形成してもよい。   Moreover, you may comprise a pair of cyclic | annular part by forming in the umbrella shape which spreads toward the other party, respectively. In this case, for example, the other annular part is formed with higher rigidity than the one annular part, and the tip part of the one annular part is formed so as to contact the inner peripheral surface of the other annular part. Also good.

この場合において、一対の環状部は、互いに先端面同士が当接するとともに、キャビティの内部が負圧のときに、それぞれ撓み変形して相手側の環状部を押圧する形状に形成されてなるものとする。これによれば、キャビティ内が負圧になると、一対の環状部は、互いに撓み変形して押し付け合うことから、一方の環状部だけを撓み変形させる場合と比べて環状部同士の密着力が高められ、防水性を一層向上させることができる。   In this case, the pair of annular portions are formed in a shape in which the tip surfaces are in contact with each other, and when the inside of the cavity is under negative pressure, each is bent and deformed to press the opposite annular portion. To do. According to this, when the inside of the cavity has a negative pressure, the pair of annular portions are deformed and pressed against each other, so that the adhesion between the annular portions is higher than when only one annular portion is bent and deformed. Thus, waterproofness can be further improved.

本発明によれば、キャビティ内部が負圧になっても内部に水が浸入するのを防止することができる。   According to the present invention, it is possible to prevent water from entering the inside of the cavity even when the inside of the cavity has a negative pressure.

As shown in FIG. 7, the female-side annular portion 81 is formed to be elastically deformable so as to be spread outward when contacting the male-side annular portion 51 having a relatively large rigidity. The gap between the open end 47 of the storage chamber 29 and the open end 77 of the female terminal storage chamber 69 is sealed with water.

また、このように雄側環状部５１との水封状態を形成する雌側環状部８１は、コネクタ１１の内部（例えば、端子収容室２９，６９）の圧力が外部の圧力（大気圧）に対して負圧になり、所定の圧力差が生じたときに、撓み変形して雄側環状部５１を全周にわたって押圧する形状に形成される。この場合の形状には、雌側環状部５１の厚みや軸方向に対する角度、外形形状等が含まれる。   In addition, in the female-side annular portion 81 that forms a water-sealed state with the male-side annular portion 51 in this way, the pressure inside the connector 11 (for example, the terminal accommodating chambers 29 and 69) is changed to the external pressure (atmospheric pressure). On the other hand, when a negative pressure is generated and a predetermined pressure difference is generated, it is bent and deformed so as to press the male side annular portion 51 over the entire circumference. The shape in this case includes the thickness of the female annular portion 51, the angle with respect to the axial direction, the outer shape, and the like.

これに対し、雄側環状部５１は、内部空間９９が負圧になっても、撓み変形することがないように比較的高い剛性を有して形成される。   On the other hand, the male-side annular portion 51 is formed with relatively high rigidity so that it does not bend and deform even when the internal space 99 becomes negative pressure.

次に、両ハウジングを嵌合する際の動作の一例を説明する。まず、図１に示すように、雄ハウジング１７の雄端子収容室２９に対して、ゴム栓９５を装着した電線２５が接続される雄端子２１をゴム栓９５とともに収容する。また、雌ハウジング１９の雌端子収容室６９に対して、ゴム栓９７を装着した電線２７が接続される雌端子２３をゴム栓９７とともに収容する。この状態で、図８の矢印で示すように、雌ハウジング１９と雄ハウジング１７を互いに近づける。   Next, an example of operation | movement at the time of fitting both housings is demonstrated. First, as shown in FIG. 1, the male terminal 21 to which the electric wire 25 equipped with the rubber plug 95 is connected is accommodated together with the rubber plug 95 in the male terminal accommodating chamber 29 of the male housing 17. Further, the female terminal 23 to which the electric wire 27 fitted with the rubber plug 97 is connected is accommodated in the female terminal accommodating chamber 69 of the female housing 19 together with the rubber plug 97. In this state, as shown by the arrow in FIG. 8, the female housing 19 and the male housing 17 are brought close to each other.

雌ハウジング１９が雄ハウジング１７のフード部３５に挿入されると、雌ハウジング１９の一対の突条部８３がそれぞれ雄ハウジング１７の第１切り欠き部４１を通過するとともに、雌ハウジング１９の係止部８７が雄ハウジング１７の第２切り欠き部４３を通過する。また、雌ハウジング１９の段差部８５が、雄ハウジング１７の案内溝３７に沿って案内される。   When the female housing 19 is inserted into the hood portion 35 of the male housing 17, the pair of protrusions 83 of the female housing 19 pass through the first cutout portions 41 of the male housing 17 and the female housing 19 is locked. The portion 87 passes through the second cutout portion 43 of the male housing 17. Further, the stepped portion 85 of the female housing 19 is guided along the guide groove 37 of the male housing 17.

雌ハウジング１９の挿入が進むと、雌ハウジング１９の係止部８７の傾斜面８９に沿って、雄ハウジング１７のロックアーム５３が係止部８７に乗り上げて、アーム部６１が上方に撓み変形する。そして、アーム部６１のロック部６３が係止部８７を乗り越えたところでアーム部６１が弾性復帰する。これにより、係止部８７がロック部６３に係止されて、両ハウジングが正規の嵌合位置にロックされる。   As the insertion of the female housing 19 proceeds, the lock arm 53 of the male housing 17 rides on the locking portion 87 along the inclined surface 89 of the locking portion 87 of the female housing 19, and the arm portion 61 is bent upward and deformed. . Then, when the lock portion 63 of the arm portion 61 gets over the locking portion 87, the arm portion 61 is elastically restored. Thereby, the latching | locking part 87 is latched by the lock | rock part 63, and both housings are locked to a regular fitting position.

また、これとともに、雌側環状部８１は、雄側環状部５１の前端面４５の周縁に内周面８１ａが全周にわたって押圧されて押し広げられるが、この弾性変形によって発生する復元力が雄側環状部５１を押し付けるため、雄側環状部５１と雌側環状部８１は全周にわたって互いに密着される。これにより、雄端子収容室２９の開口端４７と雌端子収容室６９の開口端７７との隙間が水封される。   At the same time, the female-side annular portion 81 is expanded by the inner peripheral surface 81a being pressed over the entire periphery of the front end surface 45 of the male-side annular portion 51, but the restoring force generated by this elastic deformation is increased by the male. In order to press the side annular portion 51, the male side annular portion 51 and the female side annular portion 81 are brought into close contact with each other over the entire circumference. As a result, the gap between the opening end 47 of the male terminal housing chamber 29 and the opening end 77 of the female terminal housing chamber 69 is sealed with water.

ところで、このように水封された雄端子収容室２９と雌端子収容室６９を含むコネクタ１１の空間（以下、内部空間９９という。）は、外気温との温度差等に起因して、大気圧よりも負圧になることがある。この場合、圧力差によって、雄側環状部５１と雌側環状部８１の当接部分の僅かな隙間から各環状部５１，８１の外周面等に付着した液体が内部空間９９に取り込まれることが懸念される。   By the way, the space (hereinafter referred to as the internal space 99) of the connector 11 including the male terminal accommodating chamber 29 and the female terminal accommodating chamber 69 sealed in this manner is large due to a temperature difference from the outside air temperature. There may be negative pressure rather than atmospheric pressure. In this case, due to the pressure difference, the liquid adhering to the outer peripheral surface of each of the annular portions 51, 81 may be taken into the internal space 99 from a slight gap between the contact portions of the male-side annular portion 51 and the female-side annular portion 81. Concerned.

この点、本実施形態では、弾力性（可撓性）を有する雌側環状部８１が、内部空間９９の負圧により撓み変形して、雄側環状部５１の前端面４５の周縁を押圧するようになっている。そのため、内部空間９９が負圧のときには、雄側環状部５１と雌側環状部８１との当接部分の水密性が高められるから、内部空間９９に液が浸入するのを防ぐことができる。この場合、雄側環状部５１は、剛性を有しており、負圧により撓み変形することがないため、雌側環状部８１により確実に押圧される。   In this respect, in the present embodiment, the female side annular portion 81 having elasticity (flexibility) is bent and deformed by the negative pressure of the internal space 99 and presses the periphery of the front end surface 45 of the male side annular portion 51. It is like that. Therefore, when the internal space 99 has a negative pressure, the water tightness of the contact portion between the male-side annular portion 51 and the female-side annular portion 81 is improved, so that liquid can be prevented from entering the internal space 99. In this case, the male-side annular portion 51 has rigidity and is not pressed and deformed by a negative pressure, and thus is reliably pressed by the female-side annular portion 81.

なお、雄端子収容室２９は、電線２５の外周面と貫通孔４９の内周面との隙間がゴム栓９５で封止され、雌端子収容室６９は、電線２７の外周面と貫通孔７９の内周面との隙間がゴム栓９７で封止されているため、負圧が生じても、貫通孔４９，７９から水が浸入することがない。   In the male terminal accommodating chamber 29, the gap between the outer peripheral surface of the electric wire 25 and the inner peripheral surface of the through hole 49 is sealed with a rubber plug 95, and the female terminal accommodating chamber 69 is in the outer peripheral surface of the electric wire 27 and the through hole 79. Since the gap with the inner peripheral surface is sealed with the rubber plug 97, water does not enter through the through holes 49 and 79 even if a negative pressure is generated.

以上述べたように、本実施形態のコネクタ１１によれば、内部空間９９が負圧のときに、雌側環状部８１が撓み変形して、雄側環状部５１を全周にわたって押し付けるから、両環状部の当接部分の隙間から内部空間９９に液が浸入するのを防ぐことができ、コネクタ１１の防水性の低下を抑制することができる。したがって、内部空間９９に収容される端子間の短絡や腐食等を防ぐことができ、コネクタ１１の電気的な信頼性を高めることができる。   As described above, according to the connector 11 of the present embodiment, when the internal space 99 is under negative pressure, the female-side annular portion 81 is bent and deformed to press the male-side annular portion 51 over the entire circumference. It is possible to prevent the liquid from entering the internal space 99 from the gap between the contact portions of the annular portion, and it is possible to suppress a decrease in waterproofness of the connector 11. Therefore, a short circuit or corrosion between terminals accommodated in the internal space 99 can be prevented, and the electrical reliability of the connector 11 can be enhanced.

また、本実施形態のコネクタ１１では、雄側環状部５１と雌側環状部８１をそれぞれ樹脂で形成し、これらを互いに当接させて内部空間９９を水封しているから、防水用のゴムパッキン等が不要になる。そのため、ゴムパッキンの経時劣化や高圧水の破損等に起因する防水性の低下を防ぐことができ、コネクタ１１の防水性を長期間維持することができる。加えて、ゴムパッキンを設けるスペースが不要になるから、コネクタ１１の小型化を図ることができ、製造コストを削減することができる。   Further, in the connector 11 of this embodiment, the male-side annular portion 51 and the female-side annular portion 81 are each formed of resin, and these are brought into contact with each other to seal the internal space 99, so that the waterproof rubber There is no need for packing. For this reason, it is possible to prevent a decrease in waterproofness due to deterioration of the rubber packing over time, breakage of high-pressure water, and the like, and the waterproofness of the connector 11 can be maintained for a long time. In addition, since a space for providing rubber packing is not required, the connector 11 can be reduced in size, and the manufacturing cost can be reduced.

また、雌側環状部８１は、弾力性（バネ性）を有しており、全周にわたって雄側環状部５１を押圧するように形成されるから、例えば、コネクタ１１に振動が伝播されて、両環状部５１，８１が軸方向に振動したとしても、雌側環状部８１は、雄側環状部５１との接触状態を維持しながら、弾性変形して振動を吸収する。これにより、雄雌ハウジングのガタ付きが生じることがなく、振動に伴うコネクタ１１の経時劣化等を抑制することができる。   Further, since the female-side annular portion 81 has elasticity (spring property) and is formed so as to press the male-side annular portion 51 over the entire circumference, for example, vibration is propagated to the connector 11, Even if both the annular portions 51 and 81 vibrate in the axial direction, the female-side annular portion 81 elastically deforms and absorbs vibration while maintaining a contact state with the male-side annular portion 51. Thereby, the rattling of the male and female housings does not occur, and deterioration over time of the connector 11 due to vibration can be suppressed.

また、本実施形態では、比較的弾力性を有する雌側環状部８１と、高い剛性を有する雄側環状部５１とを、互いに当接させて水封状態を形成しているが、各ハウジングに対する各環状部の位置を互いに入れ替えて構成することもできる。さらに、本実施形態の雄側環状部５１は、剛性をもたせたことにより、圧力差に起因する撓み変形が生じない構造となっているが、雌側環状部８１との水密性を確保できる範囲であれば、ある程度の撓み変形は許容できる。   Further, in this embodiment, the female-side annular portion 81 having relatively elasticity and the male-side annular portion 51 having high rigidity are brought into contact with each other to form a water-sealed state. The positions of the annular portions can be replaced with each other. Furthermore, the male annular portion 51 of the present embodiment has a structure in which bending deformation due to a pressure difference does not occur due to the rigidity, but a range in which water tightness with the female annular portion 81 can be secured. If so, a certain degree of bending deformation is acceptable.

以上、本発明の実施形態を図面により詳述してきたが、以下では、本発明を実施するための他の各実施形態について説明する。ただ、これらの各実施形態はいずれも基本的に上記実施形態と同様の作用効果を生じることから、以下では、各実施形態に特徴的な構成についてだけ説明し、上記実施形態と共通の構成については説明を省略する。   As mentioned above, although embodiment of this invention has been explained in full detail with drawing, each other embodiment for implementing this invention is described below. However, since each of these embodiments basically produces the same effect as the above-described embodiment, only the configuration characteristic to each embodiment will be described below, and the configuration common to the above-described embodiment will be described. Will not be described.

本実施形態のコネクタ１０１が上記実施形態のコネクタ１１と相違する点は、雄側環状部と雌側環状部のうち一方の環状部が他方の環状部に向かって先窄みとなる傘型に形成され、先端から奥に向かって末広がりとなる他方の環状部の外周面に先端部が当接する点である。   The difference between the connector 101 of this embodiment and the connector 11 of the above embodiment is that the one annular portion of the male-side annular portion and the female-side annular portion is tapered toward the other annular portion. This is a point where the tip portion comes into contact with the outer peripheral surface of the other annular portion that is formed and expands from the tip toward the back.

図９，１０に、本実施形態におけるコネクタ１０１の嵌合状態の断面図とその要部の拡大図を示す。雌ハウジング１９の基部７１は、雌端子収容室６９の開口端部に、全周にわたって段付状に小さくした外周面を有する樹脂製の雌側環状部１０３が形成される。雌側環状部１０３は、その前端面１０５から奥に向かって末広がりとなる外周面１０３ａを有しており、内部空間９９が負圧になっても、撓み変形することがないように比較的高い剛性を有して形成される。   9 and 10 are a cross-sectional view of the connector 101 in a fitted state according to the present embodiment and an enlarged view of a main part thereof. The base portion 71 of the female housing 19 is formed with a resin-made female annular portion 103 having an outer peripheral surface that is reduced in a stepped shape over the entire circumference at the opening end of the female terminal accommodating chamber 69. The female-side annular portion 103 has an outer peripheral surface 103a that expands from the front end surface 105 toward the back, and is relatively high so that it does not bend and deform even when the internal space 99 becomes negative pressure. It is formed with rigidity.

一方、雄ハウジング１７の基部３１は、雄端子収容室２９の開口端部に、基部３１の前端面１０７から雌側環状部１０３に向かって伸延する樹脂製の雄側環状部１０９が設けられる。雄側環状部１０９は、フード部３５に包囲されて内外周面が先窄みの傘型に形成され、比較的弾力性を有している。この雄側環状部１０９は、雄雌ハウジングの嵌合時において、雌側環状部１０３の外周面１０３ａを押圧可能に形成されるとともに、コネクタ１０１の内部空間９９が負圧となって大気圧と所定の圧力差が生じたときに、撓み変形して雌側環状部１０３の外周面１０３ａを押圧する形状に形成されている。   On the other hand, the base portion 31 of the male housing 17 is provided with a male-side annular portion 109 made of resin that extends from the front end surface 107 of the base portion 31 toward the female-side annular portion 103 at the opening end portion of the male terminal accommodating chamber 29. The male-side annular portion 109 is surrounded by the hood portion 35 and is formed in an umbrella shape having a tapered inner and outer peripheral surface, and has relatively elasticity. The male-side annular portion 109 is formed so as to be able to press the outer peripheral surface 103a of the female-side annular portion 103 when the male and female housings are fitted, and the internal space 99 of the connector 101 becomes negative pressure and atmospheric pressure. When a predetermined pressure difference occurs, it is formed into a shape that bends and deforms and presses the outer peripheral surface 103 a of the female-side annular portion 103.

本実施形態によれば、雌側環状部１０３が全周にわたって雄側環状部１０９に押圧されるから、雄端子収容室２９の開口端１１１と雌端子収容室６９の開口端１１３との隙間が水封される。   According to this embodiment, since the female-side annular portion 103 is pressed by the male-side annular portion 109 over the entire circumference, there is a gap between the opening end 111 of the male terminal accommodating chamber 29 and the opening end 113 of the female terminal accommodating chamber 69. Sealed with water.

特に、弾力性を有する雄側環状部１０９は、内部空間９９が大気圧に対して負圧になると、撓み変形して、雌側環状部１０３の外周面１０３ａを押圧するから、雌側環状部１０３と雄側環状部１０９との当接部分の水密性が高められ、内部空間９９に液が取り込まれるのを防ぐことができる。   In particular, the elastic male side annular portion 109 is bent and deformed when the internal space 99 becomes a negative pressure with respect to atmospheric pressure, and presses the outer peripheral surface 103a of the female side annular portion 103. The water tightness of the abutting portion between 103 and the male annular portion 109 is enhanced, and the liquid can be prevented from being taken into the internal space 99.

また、本実施形態では、弾力性を有する雄側環状部１０９が先窄みの傘型に形成されているから、例えば、ロックアーム５３の周囲の開口を介して高圧の洗浄液がフード部３５の内側に進入し、雄側環状部１０９に噴き付けられたとしても、雄側環状部１０９のめくれ上がりを抑制することができる。したがって、雄側環状部１０９と雌側環状部１０３との当接部分の水密性が保持され、内部空間９９に水が浸入するのを防ぐことができる。   Further, in the present embodiment, the elastic male side annular portion 109 is formed in a tapered umbrella shape, so that, for example, a high-pressure cleaning liquid is supplied to the hood portion 35 through the opening around the lock arm 53. Even if it enters inside and is sprayed on the male side annular part 109, the male side annular part 109 can be prevented from turning up. Therefore, the water tightness of the contact portion between the male-side annular portion 109 and the female-side annular portion 103 is maintained, and water can be prevented from entering the internal space 99.

本実施形態では、比較的弾力性を有する雄側環状部１０９と、剛性を有する雌側環状部１０３とを互いに当接させて水封構造を形成しているが、各ハウジングに対する各環状部の位置を互いに入れ替えて構成することもできる。さらに、本実施形態の雌側環状部１０３は、剛性をもたせたことにより、圧力差に起因する撓み変形が生じない構造となっているが、雄側環状部１０９との水密状態を確保できる範囲であれば、ある程度の撓み変形は許容できる。   In this embodiment, the water-sealing structure is formed by bringing the male-side annular portion 109 having relatively elasticity and the female-side annular portion 103 having rigidity into contact with each other. It is also possible to configure by replacing the positions with each other. Furthermore, the female-side annular portion 103 of the present embodiment has a structure in which bending deformation due to a pressure difference does not occur due to the rigidity, but a range in which a watertight state with the male-side annular portion 109 can be secured. If so, a certain degree of bending deformation is acceptable.

次に、他の実施形態について説明する。本実施形態のコネクタが上記の各実施形態のコネクタ１１と相違する点は、樹脂製の雄側環状部と雌側環状部がそれぞれ相手側に向かって末広がりの傘型に形成され、その先端面同士が互いに当接している点である。   Next, another embodiment will be described. The difference of the connector of this embodiment from the connector 11 of each of the above embodiments is that the male male annular portion and the female annular portion are formed in an umbrella shape that spreads toward the other side, and its tip surface. The point is that they are in contact with each other.

図１１，１２に、本実施形態におけるコネクタ１２１の嵌合状態の断面図とその要部の拡大図を示す。本実施形態の雌側環状部１２３は、雄側環状部１２５に向かって末広がりとなる傘型に形成され、図６の雌側環状部８１と同様に構成される。一方、雄側環状部１２５は、雌側環状部１２３と前後対称に配置され、基部３１の前端面１０７から雌側環状部１２３に向かって末広がりに伸延する傘型に形成される。雌側環状部１２３と雄側環状部１２５は、雄雌ハウジングの嵌合時において、互いに先端面（前端面）同士を全周にわたって当接して、それぞれ相手側の環状部を押圧可能に形成するとともに、コネクタ１２１の内部空間９９が負圧となり、大気圧と所定の圧力差が生じたときに、撓み変形して、相手側の環状部を押圧する形状に形成される。   11 and 12 show a cross-sectional view of the connector 121 in a fitted state in this embodiment and an enlarged view of the main part thereof. The female-side annular portion 123 of the present embodiment is formed in an umbrella shape that expands toward the male-side annular portion 125, and is configured similarly to the female-side annular portion 81 of FIG. On the other hand, the male-side annular portion 125 is disposed symmetrically with the female-side annular portion 123 and is formed in an umbrella shape that extends from the front end surface 107 of the base portion 31 toward the female-side annular portion 123 so as to spread outwardly. The female-side annular portion 123 and the male-side annular portion 125 are formed so that the distal end surfaces (front end surfaces) are in contact with each other over the entire circumference when the male and female housings are fitted, and the opposite annular portion can be pressed. At the same time, when the internal space 99 of the connector 121 becomes negative pressure and a predetermined pressure difference is generated from the atmospheric pressure, the connector 121 is bent and deformed to press the other annular portion.

本実施形態によれば、雌側環状部１２３と雄側環状部１２５が全周にわたって互いに端面同士を押圧し合うようになっている。そのため、両端面間の隙間の水密性を上記の各実施形態よりも高めることができ、雄端子収容室２９の開口端１１１と雌端子収容室６９の開口端１１３との隙間をより確実に水封することができる。   According to the present embodiment, the female-side annular portion 123 and the male-side annular portion 125 press the end surfaces with each other over the entire circumference. Therefore, the water tightness of the gap between both end faces can be improved as compared with the above embodiments, and the gap between the opening end 111 of the male terminal accommodating chamber 29 and the opening end 113 of the female terminal accommodating chamber 69 can be more reliably watered. Can be sealed.

特に、内部空間９９が大気圧に対して負圧になると、雌側環状部１２３と雄側環状部１２５がそれぞれ撓み変形して、相手側の環状部を押圧するから、雌側環状部１２３と雄側環状部１２５との当接部分の水密性が上記の各実施形態よりも高められ、内部空間９９に液が浸入するのをより確実に防ぐことができる。   In particular, when the internal space 99 becomes negative with respect to the atmospheric pressure, the female annular portion 123 and the male annular portion 125 are each deformed and pressed to press the opposite annular portion. The water tightness of the contact portion with the male-side annular portion 125 is enhanced as compared with the above embodiments, and the liquid can be more reliably prevented from entering the internal space 99.

なお、本実施形態では、雌側環状部１２３と雄側環状部１２５が互いに端面同士で当接する例を説明したが、雌側環状部１２３と雄側環状部１２５は、一方の先端部が他方の内周面に当接するように形成することもできる。この場合、他方の内周面に当接する一方の環状部は、他方の環状部よりも撓み変形量が少なくなるように形成することで、内部空間９９が負圧になっても、両環状部の水密性を確保することができる。   In the present embodiment, an example has been described in which the female-side annular portion 123 and the male-side annular portion 125 are in contact with each other at their end faces. However, one end of the female-side annular portion 123 and the male-side annular portion 125 is the other. It can also form so that it may contact | abut to the internal peripheral surface. In this case, the one annular portion that contacts the other inner peripheral surface is formed so that the amount of bending deformation is smaller than that of the other annular portion, so that both annular portions even when the internal space 99 becomes negative pressure. It is possible to ensure water tightness.
