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、自動二輪車等の移動体には、異なる電線同士を接続する防水コネクタが搭載される。この種のコネクタは、電線が接続された雄端子を収容する雄ハウジングと、他の電線が接続された雌端子を収容する雌ハウジングとを備えて構成される。そして、雄ハウジングが雌ハウジングに嵌挿されたときに、雄ハウジングの外周面と雌ハウジングの内周面との間に形成される隙間にゴムパッキンが設けられることで、ハウジング間の隙間から水が浸入するのを防いでいる。
Conventionally, a waterproof connector for connecting different electric wires is mounted on a moving body such as a motorcycle. This type of connector includes a male housing that houses a male terminal to which an electric wire is connected, and a female housing that houses a female terminal to which another electric wire is connected. Then, when the male housing is inserted into the female housing, the rubber packing is provided in the gap formed between the outer peripheral surface of the male housing and the inner peripheral surface of the female housing, so that water is discharged from the gap between the housings. Is prevented from entering.
これに対し、特許文献１には、ゴムパッキンを使用することなく、ハウジング同士をシールするコネクタの防水構造が開示されている。この防水コネクタは、一方のハウジングが筒状の内側フード部を周方向から外側フード部で包囲して形成され、他方のハウジングが外筒の内周面と外周面の両方にそれぞれ環状のシール突部を設けて形成される。
On the other hand, Patent Document 1 discloses a waterproof structure for a connector that seals housings without using rubber packing. In this waterproof connector, one housing encloses a cylindrical inner hood portion from the circumferential direction with an outer hood portion, and the other housing has annular seal protrusions on both the inner and outer peripheral surfaces of the outer cylinder. It is formed by providing a part.
これによれば、一方のハウジングを他方のハウジングに嵌挿させたときに、外筒の外周面のシール突部が外側フード部の内周面と周方向で当接され、外筒の内周面のシール突部が内側フード部の外周面と周方向で当接される。これにより、外側フード部と外筒との隙間、及び、内側フード部と外筒との隙間の２箇所に防水構造が形成されるから、ゴムパッキンを用いることなく、防水性を確保することができる。
According to this, when one housing is fitted into the other housing, the seal protrusion on the outer peripheral surface of the outer cylinder comes into contact with the inner peripheral surface of the outer hood portion in the circumferential direction, and the inner periphery of the outer cylinder The surface seal protrusion is in contact with the outer peripheral surface of the inner hood portion in the circumferential direction. As a result, a waterproof structure is formed at two locations, the gap between the outer hood portion and the outer cylinder, and the gap between the inner hood portion and the outer cylinder, so that waterproofness can be ensured without using rubber packing. it can.
ところで、上記特許文献１の防水構造の場合、ハウジング同士の組付け時において、他方のハウジングの各シール突部が一方のハウジングの各フード部を押し付けながら移動する。このため、シール突部と各フード部との摩擦によりハウジング同士が嵌合するときの嵌合負荷が大きくなり、組付け作業の負担が大きくなるという問題がある。
By the way, in the case of the waterproof structure of the above-mentioned Patent Document 1, when the housings are assembled, the seal protrusions of the other housing move while pressing the hood portions of the one housing. For this reason, there is a problem that the fitting load when the housings are fitted with each other due to the friction between the seal projection and each hood increases, and the burden of the assembling work increases.
また、シール突部が各フード部と接触することでシール突部が削れることがある。この場合、シール突部の削れカスが両ハウジングの隙間に挟まると、両ハウジングが正規の位置で嵌合できなくなるおそれがある。更に、シール突部が各フード部と接触して変形した場合、シール突部が外筒の内周面や外周面を押し付ける力が弱くなり、シール性が低下するおそれがある。
Also, the seal protrusion may be scraped by the seal protrusion coming into contact with each hood. In this case, if the scrap residue of the seal protrusion is caught in the gap between the two housings, there is a possibility that the two housings cannot be fitted at the proper positions. Further, when the seal protrusion deforms in contact with each hood portion, the force with which the seal protrusion presses the inner peripheral surface or outer peripheral surface of the outer cylinder is weakened, which may reduce the sealing performance.
本発明は、このような問題に鑑みてなされたものであり、コネクタの組付け時におけるコネクタの変形や削れによる不具合の発生を防ぐとともに、ハウジング同士の嵌合負荷を低減することを課題とする。

環状部材４１は、雄ハウジング２３と雌ハウジング４９とが互いに正規位置で嵌合したときに、第１筒部８７の内周面には、内筒部２７の開口端３３の周縁が全周に亘って当接し、かつ、第２筒部８９の内周面には、本体部６１の開口端６７の周縁が全周に亘って当接する。また、このとき、環状部材４１は、第１筒部８７が内筒部２７に押圧され、かつ、第２筒部８９が本体部６１に押圧されることで、両筒部８７，８９の内周面が拡張する方向（軸方向で縮まる方向）に弾性変形するように構成されている。
In the annular member 41, when the male housing 23 and the female housing 49 are fitted to each other at regular positions, the peripheral edge of the opening end 33 of the inner cylinder part 27 is on the entire circumference on the inner peripheral surface of the first cylinder part 87. Further, the peripheral edge of the opening end 67 of the main body portion 61 is in contact with the inner peripheral surface of the second cylindrical portion 89 over the entire circumference. Further, at this time, the annular member 41 is configured such that the first cylindrical portion 87 is pressed against the inner cylindrical portion 27 and the second cylindrical portion 89 is pressed against the main body portion 61, so The peripheral surface is configured to elastically deform in a direction in which the peripheral surface expands (a direction in which the peripheral surface contracts in the axial direction).
環状部材４１は、外周面に単数又は複数の突起部９１が設けられる。突起部９１は、外筒部２９の内面に形成される凹部９３と係合可能に構成されている。本実施形態では、図６に示すように、外筒部２９の内面において、凹部９３と連なる溝部９４が外筒部２９の開口端から軸方向に沿って形成される。環状部材４１は、突起部９１が溝部９４に係合された状態で外筒部２９の奥に押し込まれ、突起部９１が凹部９３と係合されたときに、内筒部２７の開口端３３の周縁が第１筒部８７の内周面と当接され、このときの姿勢が保持される（図５の（ｂ）参照）。なお、凹部９３は、突起部９１が係合する状態である程度の隙間が設けられ、突起部９１に対してガタ付きをもたせている。
The annular member 41 is provided with one or a plurality of protrusions 91 on the outer peripheral surface. The protrusion 91 is configured to be engageable with a recess 93 formed on the inner surface of the outer cylinder portion 29. In the present embodiment, as shown in FIG. 6, on the inner surface of the outer cylindrical portion 29, a groove portion 94 that is continuous with the concave portion 93 is formed along the axial direction from the opening end of the outer cylindrical portion 29. The annular member 41 is pushed into the outer cylindrical portion 29 in a state where the protruding portion 91 is engaged with the groove portion 94, and when the protruding portion 91 is engaged with the recessed portion 93, the opening end 33 of the inner cylindrical portion 27. Is brought into contact with the inner peripheral surface of the first cylindrical portion 87, and the posture at this time is maintained (see FIG. 5B). In addition, the recessed part 93 is provided with a certain amount of clearance in a state in which the protruding part 91 is engaged, and the protruding part 91 has a backlash.
上述した防水コネクタ１１を組み立てる際には、まず、雄ハウジング２３の貫通孔３５から電線２１が接続された雄端子１７を挿入し、雄端子１７を雄端子収容室３１の所定位置に収容してランスで保持するとともに、電線２１に装着された防水栓８３を貫通孔３５に押し込んで貫通孔３５との隙間をシールする。
When assembling the waterproof connector 11 described above, first, the male terminal 17 to which the electric wire 21 is connected is inserted from the through hole 35 of the male housing 23, and the male terminal 17 is accommodated in a predetermined position of the male terminal accommodating chamber 31. While holding with the lance, the waterproof plug 83 attached to the electric wire 21 is pushed into the through hole 35 to seal the gap with the through hole 35.
一方、雌ハウジング４９の貫通孔６９から電線５７が接続された雌端子１９を挿入し、雌端子１９を雌端子収容室６５の所定位置に収容してランスで保持するとともに、電線５７に装着された防水栓８３を貫通孔６９に差し込んで貫通孔６９との隙間をシールする。
On the other hand, the female terminal 19 to which the electric wire 57 is connected is inserted from the through hole 69 of the female housing 49, and the female terminal 19 is accommodated in a predetermined position of the female terminal accommodating chamber 65 and held by a lance, and attached to the electric wire 57. The waterproof plug 83 is inserted into the through hole 69 to seal the gap with the through hole 69.
次に、環状部材４１が雄ハウジング２３の外筒部２９に組み付けられる。このとき、環状部材４１は、突起部９１が外筒部２９の内壁の溝部９４に嵌め込まれた状態で、外筒部２９に押し込まれる。外筒部２９に押し込まれた環状部材４１は、突起部９１が溝部９４と連続する凹部９３と係合するとともに、第１筒部８７の内周面に内筒部２７の開口端３３の周縁が当接し、この姿勢が保持される。
Next, the annular member 41 is assembled to the outer cylinder portion 29 of the male housing 23. At this time, the annular member 41 is pushed into the outer cylinder portion 29 in a state where the protrusion 91 is fitted in the groove portion 94 of the inner wall of the outer cylinder portion 29. The annular member 41 pushed into the outer cylindrical portion 29 engages with the concave portion 93 where the projecting portion 91 continues to the groove portion 94, and the peripheral edge of the opening end 33 of the inner cylindrical portion 27 on the inner peripheral surface of the first cylindrical portion 87. Abut and this posture is maintained.
続いて、図４に示すように、雄ハウジング２３と雌ハウジング４９とが向き合わされ、雄ハウジング２３と雌ハウジング４９とが互いに近づけられる。このとき、雄ハウジング２３は、第１ガイドリブ４５と第２ガイドリブ４７とがそれぞれ雌ハウジング４９の案内溝５１に嵌め込まれ、正規の姿勢を保ちながら、本体部６１とフード部６３との間に外筒部２９が案内される。
Subsequently, as shown in FIG. 4, the male housing 23 and the female housing 49 face each other, and the male housing 23 and the female housing 49 are brought close to each other. At this time, in the male housing 23, the first guide rib 45 and the second guide rib 47 are respectively fitted in the guide grooves 51 of the female housing 49, and the male housing 23 is placed between the main body 61 and the hood 63 while maintaining a normal posture. The cylinder part 29 is guided.
こうして、雄ハウジング２３と雌ハウジング４９とが互いに近づけられると、まず、雄ハウジング２３の開口端３３から突出する雄タブ３９の先端部が、雌ハウジング４９の開口端６７を介して雌端子１９の電気接触部７３（図３参照）に侵入する。
Thus, when the male housing 23 and the female housing 49 are brought close to each other, first, the tip of the male tab 39 protruding from the opening end 33 of the male housing 23 is connected to the female terminal 19 via the opening end 67 of the female housing 49. It penetrates into the electrical contact portion 73 (see FIG. 3).
続いて、図５の（ａ）に示すように、雌ハウジング４９を雄ハウジング２３に対して正規の位置に嵌合させると、雌ハウジング４９の本体部６１の開口端６７の周縁が、環状部材４１の第２筒部８９の内周面と当接する（図５の（ｂ）参照）。また、雄タブ３９の先端部が、雌端子１９の電気接触部７３の正規の位置に収容される。これにより、雄端子１７と雌端子１９との電気的な接続が完了する。
Subsequently, as shown in FIG. 5A, when the female housing 49 is fitted to the male housing 23 in a proper position, the peripheral edge of the opening end 67 of the main body 61 of the female housing 49 is an annular member. 41 abuts on the inner peripheral surface of the second cylindrical portion 89 (see FIG. 5B). Further, the distal end portion of the male tab 39 is accommodated in a regular position of the electrical contact portion 73 of the female terminal 19. Thereby, the electrical connection between the male terminal 17 and the female terminal 19 is completed.
そして、環状部材４１と当接した本体部６１は、開口端６７の周縁が環状部材４１における第２筒部８９の内周面を周方向より押圧する。このため、環状部材４１は、第１筒部８７及び第２筒部８９の内周面がそれぞれ拡がる方向（軸方向で縮まる方向）に弾性変形する。その結果、内筒部２７の開口端３３の周縁と本体部６１の開口端６７の周縁には、第１筒部８７と第２筒部８９とが弾性変形したときの復元力（バネ力）がそれぞれ全周に作用する。したがって、内筒部２７の開口端３３の周縁と本体部６１の開口端６７の周縁は、それぞれ環状部材４１に強く押し付けられるから、雄ハウジング２３の開口端３３の周縁と雌ハウジング４９の開口端６７の周縁との隙間は、環状部材４１を介して気密にシールされる。
And the main-body part 61 contact | abutted with the annular member 41 presses the inner peripheral surface of the 2nd cylinder part 89 in the annular member 41 from the circumferential direction with the periphery of the opening end 67. FIG. For this reason, the annular member 41 is elastically deformed in the direction in which the inner peripheral surfaces of the first cylinder part 87 and the second cylinder part 89 expand (direction in which the inner peripheral surface contracts in the axial direction). As a result, the restoring force (spring force) when the first cylindrical portion 87 and the second cylindrical portion 89 are elastically deformed at the peripheral edge of the opening end 33 of the inner cylindrical portion 27 and the peripheral edge of the opening end 67 of the main body portion 61. Acts on the entire circumference. Accordingly, the peripheral edge of the opening end 33 of the inner cylinder part 27 and the peripheral edge of the opening end 67 of the main body part 61 are strongly pressed against the annular member 41, respectively. The gap with the peripheral edge of 67 is hermetically sealed through the annular member 41.
一方、雄ハウジング２３と雌ハウジング４９とが近づく過程で、雄ハウジング２３に設けられたロック突起４３は、雌ハウジング４９のロックアーム５３に形成された第１連結部７９と接触し、第１連結部７９と連なる一対の脚部７５を弾性変形させることで、第１連結部７９を乗り越え、係合部５５と係合する。これにより、雌ハウジング４９と雄ハウジング２３との相対位置が保持され、本体部６１の開口端６７の周縁が環状部材４１の第２筒部８９の内周面を押し付ける状態が保持される。このため、環状部材４１と本体部６１の開口端６７の周縁との隙間や、環状部材４１と内筒部２７の開口端３３の周縁との隙間を介して水が浸入するのを防ぐことができる。
On the other hand, in the process in which the male housing 23 and the female housing 49 approach each other, the lock protrusion 43 provided on the male housing 23 comes into contact with the first connection portion 79 formed on the lock arm 53 of the female housing 49, and the first connection. The pair of leg portions 75 connected to the portion 79 are elastically deformed to get over the first connecting portion 79 and engage with the engaging portion 55. Accordingly, the relative position between the female housing 49 and the male housing 23 is maintained, and the state in which the peripheral edge of the opening end 67 of the main body 61 presses the inner peripheral surface of the second cylindrical portion 89 of the annular member 41 is maintained. For this reason, it is possible to prevent water from entering through a gap between the annular member 41 and the peripheral edge of the opening end 67 of the main body 61 or a clearance between the annular member 41 and the peripheral edge of the opening end 33 of the inner cylinder part 27. it can.
更に、貫通孔３５と電線２１との隙間は、防水栓８３でシールされ、貫通孔６９と電線５７との隙間は、防水栓８５でシールされている。このため、雄端子収容室３１と雌端子収容室６５は、外部からの水の浸入を完全に防ぐことができるから、雄端子１７と雌端子１９との接続状態を良好に保つことができる。
Furthermore, the gap between the through hole 35 and the electric wire 21 is sealed with a waterproof plug 83, and the gap between the through hole 69 and the electric wire 57 is sealed with a waterproof plug 85. For this reason, since the male terminal accommodating chamber 31 and the female terminal accommodating chamber 65 can completely prevent the entry of water from the outside, the connection state between the male terminal 17 and the female terminal 19 can be kept good.
また、環状部材４１は、弾性変形可能な状態で内筒部２７と本体部６１との間に挟持されるから、例えば、防水コネクタ１１が振動するときには、環状部材４１が軸方向で伸縮するように弾性変形を繰り返すことで、振動を吸収することができる。これにより、雄端子１７及び雌端子１９に振動が伝播するのを抑制することができるから、端子間の電気的な接続状態を良好に維持することができる。
Further, since the annular member 41 is sandwiched between the inner cylinder portion 27 and the main body portion 61 in a state where it can be elastically deformed, for example, when the waterproof connector 11 vibrates, the annular member 41 expands and contracts in the axial direction. By repeating elastic deformation, vibration can be absorbed. Thereby, since it can suppress that a vibration propagates to the male terminal 17 and the female terminal 19, the electrical connection state between terminals can be maintained favorable.
以上述べたように、本実施形態では、雄ハウジング２３における内筒部２７の開口端３３の周縁と、雌ハウジング４９における本体部６１の開口端６７の周縁との隙間に樹脂製の環状部材４１が設けられる。そして、この環状部材４１は、雄ハウジング２３と雌ハウジング４９とが正規の位置で嵌合するときに、内筒部２７と本体部６１に押圧されて弾性変形する。その結果、内筒部２７の開口端３３の周縁と環状部材４１との接触領域、及び、本体部６１の開口端６７の周縁と環状部材４１との接触領域は、周方向で強く密着されるから、これらの接触領域を介して水の浸入を防ぐことができる。なお、本実施形態の防水コネクタ１１は、本体部６１の開口端６７が、環状部材４１を弾性変形可能な範囲で押圧するように、環状部材４１を押し付ける押し付け量（挿入量）が適宜設定される。
As described above, in the present embodiment, the resin-made annular member 41 is formed in the gap between the peripheral edge of the opening end 33 of the inner cylindrical portion 27 in the male housing 23 and the peripheral edge of the opening end 67 of the main body 61 in the female housing 49. Is provided. The annular member 41 is pressed and elastically deformed by the inner cylinder portion 27 and the main body portion 61 when the male housing 23 and the female housing 49 are fitted in a regular position. As a result, the contact area between the peripheral edge of the opening end 33 of the inner cylindrical portion 27 and the annular member 41 and the contact area between the peripheral edge of the opening end 67 of the main body 61 and the annular member 41 are strongly adhered in the circumferential direction. Therefore, it is possible to prevent water from entering through these contact areas. In the waterproof connector 11 of the present embodiment, the pressing amount (insertion amount) for pressing the annular member 41 is appropriately set so that the opening end 67 of the main body 61 presses the annular member 41 within a range in which the annular member 41 can be elastically deformed. The
本実施形態によれば、雄ハウジング２３と雌ハウジング４９との嵌合時において、本体部６１の開口端６７の周縁は、環状部材４１と当接するまで非接触の状態が維持されるから、雄ハウジング２３と雌ハウジング４９との嵌合に伴う損傷を防ぐことができ、しかも両ハウジングの嵌合負荷が小さくなることで、組付け作業の負担を小さくすることができる。
According to the present embodiment, when the male housing 23 and the female housing 49 are fitted, the peripheral edge of the opening end 67 of the main body 61 is maintained in a non-contact state until it contacts the annular member 41. Damage due to the fitting between the housing 23 and the female housing 49 can be prevented, and the fitting load between the two housings can be reduced, so that the burden of the assembling work can be reduced.
本実施形態によれば、従来のシール構造で一般に使用されるゴムパッキンを廃止することができるから、コネクタの軸方向と交差する方向の幅寸法において、ゴムパッキンの肉厚分を盛り込む必要がなく、結果としてコネクタのコンパクト化を図ることができる。
According to this embodiment, since the rubber packing generally used in the conventional seal structure can be eliminated, it is not necessary to include the thickness of the rubber packing in the width dimension in the direction intersecting the axial direction of the connector. As a result, the connector can be made compact.
本実施形態では、環状部材４１が外筒部２９の内側に位置（保持）されているから、例えば、経時劣化に伴う環状部材４１の弾力性の低下を抑制することができる。これにより、環状部材４１のシール性の低下と振動吸収効果を長時間保持することができる。更に、環状部材４１が汎用の合成樹脂材料等で形成されることにより、ゴム材料のような経時劣化を防ぐことができる。ただし、環状部材４１は、所定の弾性変形が可能であれば、合成樹脂以外の他の材料（例えば、ゴム材料等）で形成することもできる。
In the present embodiment, since the annular member 41 is positioned (held) inside the outer cylinder portion 29, for example, it is possible to suppress a decrease in elasticity of the annular member 41 due to deterioration over time. Thereby, the deterioration of the sealing performance of the annular member 41 and the vibration absorption effect can be maintained for a long time. Furthermore, when the annular member 41 is formed of a general-purpose synthetic resin material or the like, it is possible to prevent deterioration with time like a rubber material. However, the annular member 41 can be formed of a material other than the synthetic resin (for example, a rubber material) as long as predetermined elastic deformation is possible.
また、本実施形態では、図５に示すように、雌ハウジング４９は、本体部６１の先端部分を横断面方向からみると、軸方向と直交する方向の幅寸法が開口端６７側で小さくなる段差部９５が設けられている。このため、例えば、本体部６１の開口端６７付近に異物が付着したとしても、その異物を段差部９５に逃がすことができるから、環状部材４１と接触する本体部６１のシール面と環状部材４１との間に異物が挟まることによるシール面の損傷を防ぐことができ、シール性が低下するのを防ぐことができる。
In the present embodiment, as shown in FIG. 5, the female housing 49 has a width dimension in the direction orthogonal to the axial direction on the opening end 67 side when the distal end portion of the main body 61 is viewed from the cross-sectional direction. A step portion 95 is provided. For this reason, for example, even if foreign matter adheres to the vicinity of the opening end 67 of the main body 61, the foreign matter can be released to the stepped portion 95, and therefore, the sealing surface of the main body 61 that contacts the annular member 41 and the annular member 41. It is possible to prevent damage to the sealing surface due to foreign matter being sandwiched between them, and to prevent deterioration of the sealing performance.

例えば、環状部材は、内筒部２７に押圧されて弾性変形する第１筒部８７と、本体部６１に押圧されて弾性変形する第２筒部８９とを有していればよく、筒体の両端に第１筒部８７と第２筒部８９とをそれぞれ形成することもできる。また、図８に示すように、環状部材９７の周方向の一部において、第１筒部８７と第２筒部８９とが連なる内周面から第２筒部８９の内側に延びる支持片９９を設けることもできる。これによれば、支持片９９を内筒部２７の開口端３３に挿入することにより、環状部材９７を内筒部２７に保持することができるから、突起部９１が不要になる。また、環状部材は、内筒部や本体部の形状に合わせて筒状に形成されていればよく、断面四角形の角筒状に限らず断面多角形や断面円形等の筒状に形成することもできる。

Can also be provided. According to this, since the annular member 97 can be held on the inner cylinder part 27 by inserting the support piece 99 into the opening end 33 of the inner cylinder part 27, the protrusion 91 is not necessary. Moreover, the annular member should just be formed in the cylinder shape according to the shape of an inner cylinder part or a main-body part, and should form not only the square cylinder shape of a cross-sectional square but cylindrical shapes, such as a cross-sectional polygon and a cross-sectional circle.
