　ところでゴム栓は、防水機能だけでなくコネクタのガタ付きを抑制する機能を有する場合がある。このような場合に、経年変化等により防水性能が低下した際、防水ゴム栓を交換することにより防水性能を維持することが考えられる。 By the way, the rubber stopper may have not only the waterproof function but also the function of suppressing rattling of the connector. In such a case, it is possible to maintain the waterproof performance by replacing the waterproof rubber plug when the waterproof performance deteriorates due to aging or the like.
　しかし、コネクタのガタ付きを抑制する機能は十分に発揮できる状態であるのにゴム栓の防水性が低下する場合や、逆に、ゴム栓の防水性は十分なのにコネクタのガタ付きを抑制する機能が低下する場合において、ゴム栓全体を交換することは、部品コストの増大を生じさせる。 However, when the function of suppressing the rattling of the connector can be fully exerted, but the waterproofness of the rubber plug decreases, or conversely, the function of suppressing the rattling of the connector even though the waterproofness of the rubber plug is sufficient. In the case of decrease in the value, replacing the entire rubber plug causes an increase in parts cost.

［本開示の実施形態の説明］
　最初に本開示の実施態様を列挙して説明する。 [Description of Embodiments of the Present Disclosure]
First, embodiments of the present disclosure will be listed and described.
（１）本開示は、コネクタであって、端子と、ハウジングと、液密リングと、耐振リングと、を備え、前記ハウジングは、前記端子を収容するキャビティが設けられると共に前方に突出するタワー部を有し、前記液密リングは、前記タワー部に外嵌される弾性材料からなり、前記耐振リングは、前記液密リングよりも前方の位置で前記タワー部に外嵌される弾性材料からなる。 (1) The present disclosure is a connector, which includes a terminal, a housing, a liquid-tight ring, and a vibration-proof ring, and the housing is provided with a cavity that accommodates the terminal and a tower portion that protrudes forward. And the liquid-tight ring is made of an elastic material that is externally fitted to the tower portion, and the vibration-proof ring is made of an elastic material that is externally fitted to the tower portion at a position in front of the liquid-tight ring. ..
　タワー部に外嵌された液密リングによってコネクタの液密性を向上させると共に、タワー部に外嵌された耐振リングによってコネクタの耐振性を向上させることができる。また、液密リングと耐振リングは別部品なので、液密リングおよび耐振リングの一方の性能が低下した場合には、性能が低下した方のみを交換すればよいので、部品コストの増大を抑制することができる。 The liquid-tight ring externally fitted to the tower part can improve the liquid-tightness of the connector, and the vibration-proof ring externally fitted to the tower part can improve the vibration resistance of the connector. Further, since the liquid-tight ring and the anti-vibration ring are separate parts, when the performance of one of the liquid-tight ring and the anti-vibration ring deteriorates, it is only necessary to replace the one with the lower performance, which suppresses an increase in the parts cost. be able to.
　液密リングは耐振リングよりも後方に位置しているので、ハウジング内に液体が浸入することを確実に抑制することができる。また、耐振リングは、液密リングよりも前方に位置しているので、液密リングよりも交換が容易である。 Since the liquid-tight ring is located behind the vibration-proof ring, it is possible to reliably prevent liquid from entering the housing. Further, since the vibration-proof ring is located in front of the liquid-tight ring, it is easier to replace it than the liquid-tight ring.
（２）コネクタは、前記タワー部の前端部に取り付けられて、少なくとも前記耐振リングに前方から係止することにより前記耐振リングを保持するリテーナを備えることが好ましい。 (2) It is preferable that the connector includes a retainer that is attached to a front end portion of the tower portion and holds the vibration-proof ring by locking the vibration-proof ring at least from the front side.
　リテーナが耐振リングに前方から係止することにより、耐振リングがタワー部から外れることを抑制することができる。 　By locking the retainer to the anti-vibration ring from the front, it is possible to prevent the anti-vibration ring from coming off the tower.
（３）前記端子は相手方端子と接続する接点部を有しており、前記耐振リングは、前後方向について前記接点部と対応する位置に配されていることが好ましい。 (3) It is preferable that the terminal has a contact portion that is connected to the counterpart terminal, and that the vibration-proof ring is arranged at a position corresponding to the contact portion in the front-rear direction.
　耐振リングが接点部と対応する位置に配されているので、端子の接点部に振動が伝達されることを、耐振リングによって効果的に抑制することができる。これにより、コネクタの耐振性を向上させることができる。 Since the anti-vibration ring is arranged at the position corresponding to the contact part, it is possible to effectively suppress the transmission of vibration to the contact part of the terminal by the anti-vibration ring. Thereby, the vibration resistance of the connector can be improved.
（４）前記耐振リングは、前後方向について前記タワー部の中央位置付近に配されていることが好ましい。 (4) It is preferable that the vibration-proof ring is arranged near the central position of the tower portion in the front-rear direction.
　タワー部の中央位置付近に配された耐振リングにより、コネクタに伝達された振動を効果的に吸収することができるので、コネクタの耐振性を向上させることができる。 The vibration resistant ring located near the center of the tower section can effectively absorb the vibration transmitted to the connector, thus improving the vibration resistance of the connector.
（５）本開示は、コネクタ構成体であって、上記のコネクタと、相手方コネクタと、を備え、前記相手方コネクタは、前記タワー部に外嵌するフード部を有すると共に、前記フード部の内部に前記端子と接続される相手方端子を有し、前記相手方コネクタの前記フード部が前記コネクタの前記タワー部に外嵌した状態で、前記フード部の内壁と前記耐振リングとが弾性的に接触すると共に、前記フード部の内壁と前記液密リングとが密着している。 (5) The present disclosure is a connector structure, which includes the above connector and a mating connector, the mating connector having a hood portion that is externally fitted to the tower portion, and the inside of the hood portion. While having a mating terminal connected to the terminal, the hood portion of the mating connector is externally fitted to the tower portion of the connector, and the inner wall of the hood portion and the vibration-proof ring elastically contact with each other. The inner wall of the hood portion and the liquid-tight ring are in close contact with each other.

　図４および図５に示すように、雌コネクタ１１は、複数（本実施形態では３つ）の雌端子４５と、これらの雌端子４５が収容される複数（本実施形態では３つ）のキャビティ１７を有すると共に前方に延びるタワー部１８を備えた雌ハウジング２８と、タワー部１８に外嵌された液密リング１９と、液密リング１９よりも前方の位置でタワー部１８に外嵌された耐振リング２０と、タワー部１８の前端部に取り付けられるリテーナ２１とを備える。 <Female connector 11>
As shown in FIGS. 4 and 5, the female connector 11 includes a plurality (three in this embodiment) of female terminals 45 and a plurality of (three in this embodiment) cavities in which these female terminals 45 are accommodated. A female housing 28 having a tower portion 18 extending forward and a liquid tight ring 19 fitted to the tower portion 18, and fitted to the tower portion 18 at a position in front of the liquid tight ring 19. The vibration-proof ring 20 and the retainer 21 attached to the front end portion of the tower portion 18 are provided.
　各雌端子４５は、導電性を有する金属板材をプレス加工するなどして形成されており、図４に示すように、雄コネクタ１２に設けられた雄端子１５が挿入されて接続される筒状の接続筒部２２と、電線２３の端末に接続される電線接続部２４とを前後方向に繋げた形態とされており、電線接続部２４の後端部は、電線２３の絶縁被覆に嵌着されたゴム栓２５と共に絶縁被覆に圧着されている。接続筒部２２の内部には、弾性変形可能な弾性接触片２６が配設されている。弾性接触片２６は、接続筒部２２の前端部から斜め下後方に折り返されると共に、斜め上後方に屈曲されている。弾性接触片２６は左右方向から見て、下方に突出した谷状に形成されており、最も下方に位置する部分が、雄端子１５と接触する接点部２７とされる。 Each female terminal 45 is formed, for example, by pressing a conductive metal plate material, and as shown in FIG. 4, a cylindrical shape into which the male terminal 15 provided in the male connector 12 is inserted and connected. The connecting tube portion 22 and the electric wire connecting portion 24 connected to the end of the electric wire 23 are connected in the front-rear direction, and the rear end portion of the electric wire connecting portion 24 is fitted to the insulating coating of the electric wire 23. The rubber plug 25 is pressed against the insulating coating. An elastic contact piece 26 that is elastically deformable is disposed inside the connection tubular portion 22. The elastic contact piece 26 is folded back obliquely downward and rearward from the front end of the connecting tubular portion 22, and is bent obliquely upward rearward. The elastic contact piece 26 is formed in a valley shape protruding downward when viewed in the left-right direction, and the lowermost portion is a contact portion 27 that contacts the male terminal 15.
　雌ハウジング２８は、各雌端子４５を収容する複数のキャビティ１７が前後方向に延びて形成された端子収容部２９を有する。キャビティ１７は前方および後方に開口している。端子収容部２９の外面は、全周に亘って雌フード部３０によって囲まれている。雌フード部３０と端子収容部２９とは連結部３１によって連結されている。端子収容部２９のうち連結部３１よりも前方の部分がタワー部１８とされる。タワー部１８の前端部には、別体のリテーナ２１が前方から装着される。タワー部１８と雌フード部３０との間に雄コネクタ１２の雄フード部１３が嵌入されるようになっている。 The female housing 28 has a terminal accommodating portion 29 in which a plurality of cavities 17 accommodating the female terminals 45 extend in the front-rear direction. The cavity 17 is open to the front and the rear. The outer surface of the terminal accommodating portion 29 is surrounded by the female hood portion 30 over the entire circumference. The female hood portion 30 and the terminal accommodating portion 29 are connected by a connecting portion 31. A portion of the terminal accommodating portion 29 in front of the connecting portion 31 is the tower portion 18. A separate retainer 21 is attached to the front end of the tower portion 18 from the front. The male hood portion 13 of the male connector 12 is fitted between the tower portion 18 and the female hood portion 30.
　図２に示すように、雌フード部３０は、前方に開口した形態をなしている。図４に示すように、端子収容部２９の上壁には、前後方向に延びるロックアーム３２が形成されている。ロックアーム３２は、端子収容部２９と支点部３３によって連結されている。ロックアーム３２は、タワー部１８よりもやや後方に設けられた支点部３３を支点として、上下方向について揺動可能に形成されている。ロックアーム３２には、雄フード部１３のロック突起１６に対応する位置に、上下方向に貫通する係止孔３４が形成されている。係止孔３４の内形状はロック突起１６の外形状よりもやや大きく係止されている。ロック突起１６の前面が係止孔３４の内面に後方から当接することにより、雄コネクタ１２は、前方に抜けることが規制された状態で雌コネクタ１１に保持されるようになっている。 As shown in FIG. 2, the female hood portion 30 has a shape that is open to the front. As shown in FIG. 4, a lock arm 32 extending in the front-rear direction is formed on the upper wall of the terminal accommodating portion 29. The lock arm 32 is connected to the terminal accommodating portion 29 by a fulcrum portion 33. The lock arm 32 is formed to be swingable in the up-down direction with a fulcrum portion 33 provided slightly rearward of the tower portion 18 as a fulcrum. The lock arm 32 is formed with a locking hole 34 penetrating in the vertical direction at a position corresponding to the lock protrusion 16 of the male hood portion 13. The inner shape of the locking hole 34 is slightly larger than the outer shape of the lock protrusion 16. The front surface of the lock projection 16 comes into contact with the inner surface of the locking hole 34 from the rear side, so that the male connector 12 is held by the female connector 11 in a state in which it is restricted from coming out forward.
　雌フード部３０の内部には、前方に延びるタワー部１８が、雌フード部３０の内壁と隙間を有して形成されている。タワー部１８は左右方向に横長な形態をなしている。タワー部１８の外周には、液密リング１９と、耐振リング２０とが前後方向に並んで外嵌されるようになっている。 A tower portion 18 extending forward is formed inside the female hood portion 30 with a gap from the inner wall of the female hood portion 30. The tower portion 18 has a laterally long shape in the left-right direction. A liquid-tight ring 19 and a vibration-proof ring 20 are fitted onto the outer periphery of the tower portion 18 side by side in the front-rear direction.
　液密リング１９は、合成ゴム、天然ゴム等の弾性材料からなり、角が丸められた方形の環状に形成されている。液密リング１９の外周面には、周方向に沿って切れ目なく形成された２条の液密リップ３５が、径方向の外方に突出して形成されている（図３参照）。２条の液密リップ３５は前後方向に並んで形成されている。液密リング１９の後端部には、左右方向について外方に突出する耳部３６が形成されている。耳部３６は、雌フード部３０と、タワー部１８との隙間に嵌入されるようになっており、これにより、液密リング１９が前方に抜け止め保持されるようになっている（図５参照）。 The liquid-tight ring 19 is made of an elastic material such as synthetic rubber or natural rubber, and is formed in a rectangular ring shape with rounded corners. On the outer peripheral surface of the liquid-tight ring 19, two liquid-tight lips 35 formed continuously along the circumferential direction are formed so as to project outward in the radial direction (see FIG. 3 ). The two liquid-tight lips 35 are formed side by side in the front-rear direction. At the rear end portion of the liquid-tight ring 19, an ear portion 36 that protrudes outward in the left-right direction is formed. The ear portion 36 is adapted to be fitted in a gap between the female hood portion 30 and the tower portion 18, whereby the liquid-tight ring 19 is retained in the forward direction and retained (FIG. 5). reference).
　液密リング１９の内形状は、タワー部１８の外形状よりもやや小さく形成されている。これにより、液密リング１９がタワー部１８に外嵌した状態で、液密リング１９の内面とタワー部１８の外面とが密着するようになっている。この結果、液密リング１９の内面とタワー部１８の外面との間が、例えば、水、油等の液体に対してシールされる。 The inner shape of the liquid-tight ring 19 is formed slightly smaller than the outer shape of the tower portion 18. As a result, the inner surface of the liquid tight ring 19 and the outer surface of the tower portion 18 are in close contact with each other in a state where the liquid tight ring 19 is fitted onto the tower portion 18. As a result, the space between the inner surface of the liquid-tight ring 19 and the outer surface of the tower portion 18 is sealed against a liquid such as water or oil.
　耐振リング２０は、合成ゴム、天然ゴム等の弾性材料からなり、角が丸められた方形の環状に形成されている。耐振リング２０の外周面には、周方向に沿って切れ目なく形成された２条の耐振リップ３７が、径方向の外方に突出して形成されている。２条の耐振リップ３７は前後方向に並んで形成されている（図３参照）。耐振リング２０の内形状は、タワー部１８の外形状よりもやや小さく形成されている。 The anti-vibration ring 20 is made of an elastic material such as synthetic rubber or natural rubber, and is formed in a square annular shape with rounded corners. On the outer circumferential surface of the vibration-proof ring 20, two vibration-proof lips 37 formed continuously along the circumferential direction are formed so as to project outward in the radial direction. The two vibration-proof lips 37 are formed side by side in the front-rear direction (see FIG. 3). The inner shape of the vibration-proof ring 20 is formed to be slightly smaller than the outer shape of the tower portion 18.
　タワー部１８と雌フード部３０との間に雄フード部１３が嵌合されると、液密リング１９がタワー部１８の外周面と雄フード部１３の内周面とに密着し、タワー部１８と雄フード部１３との間を液密にシールするようになっている。 When the male hood portion 13 is fitted between the tower portion 18 and the female hood portion 30, the liquid-tight ring 19 comes into close contact with the outer peripheral surface of the tower portion 18 and the inner peripheral surface of the male hood portion 13, and the tower portion A liquid-tight seal is provided between the male hood portion 18 and the male hood portion 13.
　また、タワー部１８と雌フード部３０との間に雄フード部１３が嵌合された状態で、耐振リング２０がタワー部１８の外周面と雄フード部１３の内周面とに接触し、弾性的に圧縮される。これにより、雄コネクタ１２から雌コネクタ１１へ伝わる振動、および雌コネクタ１１から雄コネクタ１２へ伝わる振動が耐振リング２０によって吸収されるようになっている。 Further, in a state where the male hood portion 13 is fitted between the tower portion 18 and the female hood portion 30, the vibration-proof ring 20 contacts the outer peripheral surface of the tower portion 18 and the inner peripheral surface of the male hood portion 13, It is elastically compressed. Thereby, the vibration transmitted from the male connector 12 to the female connector 11 and the vibration transmitted from the female connector 11 to the male connector 12 are absorbed by the vibration-proof ring 20.
　液密リング１９と耐振リング２０との間には、角が丸められた方形の環状をなすリング部材３８が介されている（図３参照）。リング部材３８は、例えば合成樹脂を射出成型してなる。リング部材３８を構成する材料は、合成樹脂、セラミック等、任意の材料を適宜に選択することができる。リング部材３８の内形状は、タワー部１８の外形状と同じか、やや大きく設定されている。これにより、リング部材３８はタワー部１８に外嵌可能に形成されている。 A ring-shaped ring member 38 with rounded corners is interposed between the liquid-tight ring 19 and the vibration-proof ring 20 (see FIG. 3). The ring member 38 is formed by injection molding a synthetic resin, for example. As the material forming the ring member 38, any material such as synthetic resin and ceramics can be appropriately selected. The inner shape of the ring member 38 is set to be the same as or slightly larger than the outer shape of the tower portion 18. As a result, the ring member 38 is formed so that it can be fitted onto the tower portion 18.
　図４および図５に示すように、タワー部１８の内部には、雌端子４５を収容する複数のキャビティ１７が前後方向に貫通して形成されており、後方から各雌端子４５が挿入されるようになっている。各キャビティ１７の後端部は丸孔状をなしており、各雌端子４５がそれぞれのキャビティ１７内に収容されると、電線２３に嵌着されたゴム栓２５がキャビティ１７の後側内周面に密着し、電線２３とタワー部１８との間が液密にシールされるようになっている。 As shown in FIGS. 4 and 5, a plurality of cavities 17 accommodating the female terminals 45 are formed inside the tower portion 18 so as to penetrate in the front-rear direction, and the female terminals 45 are inserted from the rear side. It is like this. The rear end of each cavity 17 has a round hole shape, and when each female terminal 45 is housed in each cavity 17, the rubber plug 25 fitted to the electric wire 23 is attached to the inner periphery of the rear side of the cavity 17. The electric wire 23 and the tower portion 18 are tightly adhered to each other so as to be liquid-tightly sealed.
　キャビティ１７の内壁には、キャビティ１７の内方に突出する弾性変形可能なランス３９が形成されている。ランス３９の前端部には、キャビティ１７内に挿入された雌端子４５の接続部の後端縁に後方から係止する係止部４０が設けられている。係止部４０が雌端子４５の接続筒部２２の後端縁に後方から係止することにより、雌端子４５がキャビティ１７内に抜け止め状態で保持されるようになっている。ランス３９と、キャビティ１７の内壁との間にはランス３９が弾性変形可能な撓み空間４１が形成されている（図４参照）。 An elastically deformable lance 39 protruding inward of the cavity 17 is formed on the inner wall of the cavity 17. At the front end portion of the lance 39, a locking portion 40 that locks from the rear at the rear end edge of the connection portion of the female terminal 45 inserted into the cavity 17 is provided. By locking the locking portion 40 to the rear end edge of the connecting tubular portion 22 of the female terminal 45 from the rear side, the female terminal 45 is retained in the cavity 17 in a retaining state. Between the lance 39 and the inner wall of the cavity 17, there is formed a bending space 41 in which the lance 39 can elastically deform (see FIG. 4).
　タワー部１８の前端部には、耐振リング２０の前方の位置に、リテーナ２１が装着されるようになっている。図６および図８に示すように、リテーナ２１は、各キャビティ１７内に挿入されて、撓み空間４１内に進入する撓み規制部４２を有する。撓み規制部４２は、前後方向に細長く延びて形成されている。撓み規制部４２の後端部の上下方向についての厚さ寸法は、撓み空間４１の上下方向についての高さ寸法と略同じに形成されている。ほぼ同じとは、同じ場合を含むと共に、同じでない場合であっても実質的に同じと認定できる場合も含む。 A retainer 21 is attached to the front end of the tower 18 at a position in front of the vibration-proof ring 20. As shown in FIGS. 6 and 8, the retainer 21 has a bending restriction portion 42 that is inserted into each cavity 17 and enters the bending space 41. The bending restriction portion 42 is formed to extend in the front-rear direction in a slender shape. The thickness dimension of the rear end portion of the bending restriction portion 42 in the vertical direction is formed to be substantially the same as the height dimension of the bending space 41 in the vertical direction. The term “substantially the same” includes the same case, and includes the case where they can be recognized as substantially the same even if they are not the same.
　リテーナ２１の前端部には、前壁４３が形成されている。前壁４３の外縁部は、耐振リング２０に前方から当接して、耐振リング２０を前止まり保持するようになっている（図５参照）。 A front wall 43 is formed at the front end of the retainer 21. The outer edge portion of the front wall 43 abuts on the vibration-proof ring 20 from the front, and holds the vibration-proof ring 20 in the front stop state (see FIG. 5 ).
　図７に示すように、前壁４３には、複数（本実施形態では３つ）の窓部４４が前後方向に貫通して形成されている。図５に示すように、窓部４４は、タワー部１８のキャビティ１７に対応する位置に形成されている。これにより、リテーナ２１がタワー部１８に装着された状態で、雄端子１５は、リテーナ２１の窓部４４からタワー部１８のキャビティ１７内に進入可能になっている。 As shown in FIG. 7, a plurality of (three in this embodiment) window portions 44 are formed in the front wall 43 so as to penetrate in the front-rear direction. As shown in FIG. 5, the window portion 44 is formed at a position corresponding to the cavity 17 of the tower portion 18. As a result, with the retainer 21 attached to the tower portion 18, the male terminal 15 can enter the cavity 17 of the tower portion 18 through the window portion 44 of the retainer 21.
　コネクタ構成体１０および雌コネクタ１１の液密性を向上させる液密リング１９と、コネクタ構成体１０および雌コネクタ１１の耐振性を向上させる耐振リング２０とを別部材としたので、それぞれの物性を向上させるために最適の位置に、液密リング１９および耐振リング２０をそれぞれ配置することができる。これにより、コネクタ構成体１０および雌コネクタ１１の設計の自由度を向上させることができる。 Since the liquid-tight ring 19 for improving the liquid tightness of the connector structure 10 and the female connector 11 and the vibration resistant ring 20 for improving the vibration resistance of the connector structure 10 and the female connector 11 are separate members, their respective physical properties are The liquid-tight ring 19 and the anti-vibration ring 20 can be arranged at optimum positions for improvement. Thereby, the degree of freedom in designing the connector structure 10 and the female connector 11 can be improved.
＜本実施形態の組み付け工程の一例＞
　続いて、コネクタ構成体１０の組み付け工程の一例を説明する。コネクタ構成体１０の組み付け工程は以下の記載に限定されない。 <Example of assembly process of this embodiment>
Next, an example of the assembly process of the connector structure 10 will be described. The assembly process of the connector structure 10 is not limited to the following description.
　タワー部１８に、液密リング１９、リング部材３８、耐振リング２０が、この順序で外嵌される。これにより、タワー部１８の外周には、後方から順に、液密リング１９、リング部材３８、および耐振リング２０が並んで配されるようになっている。 The liquid-tight ring 19, the ring member 38, and the vibration-proof ring 20 are fitted onto the tower portion 18 in this order. As a result, the liquid-tight ring 19, the ring member 38, and the vibration-proof ring 20 are arranged side by side on the outer periphery of the tower portion 18 from the rear.
　キャビティ１７内に、雌端子４５が後方から挿入される。雌端子４５の接続筒部２２がランス３９に接触することによりランス３９が弾性変形する。更に雌端子４５が前方に押し込まれると、ランス３９が復帰変形し、雌端子４５の接続筒部２２の後端部にランス３９の係止部４０が後方から係止する。これにより、雌端子４５はキャビティ１７内において、後方へ抜け止めされた状態で保持される。 The female terminal 45 is inserted into the cavity 17 from the rear. When the connecting tubular portion 22 of the female terminal 45 contacts the lance 39, the lance 39 is elastically deformed. When the female terminal 45 is further pushed forward, the lance 39 is restored and deformed, and the engaging portion 40 of the lance 39 is engaged with the rear end of the connecting tubular portion 22 of the female terminal 45 from the rear. As a result, the female terminal 45 is held in the cavity 17 while being prevented from coming out backward.
　キャビティ１７内に雌端子４５が挿入される際、電線２３に外嵌されたゴム栓２５の外周が、キャビティ１７の内周に密着する。これにより、キャビティ１７の内壁とゴム栓２５の外周とが液密にシールされる。 When the female terminal 45 is inserted into the cavity 17, the outer circumference of the rubber plug 25 fitted on the electric wire 23 comes into close contact with the inner circumference of the cavity 17. As a result, the inner wall of the cavity 17 and the outer periphery of the rubber stopper 25 are liquid-tightly sealed.
　タワー部１８の前端部に、前方からリテーナ２１が装着される。リテーナ２１の撓み規制部４２がタワー部１８のキャビティ１７内に前方から進入する。更にリテーナ２１が後方に押し込まれると、撓み規制部４２が撓み空間４１内に進入する。これにより、ランス３９が弾性変形することが規制されるので、雌端子４５とランス３９との係止構造が解除されることを規制することができる。 A retainer 21 is attached to the front end of the tower portion 18 from the front. The bending restriction portion 42 of the retainer 21 enters the cavity 17 of the tower portion 18 from the front. When the retainer 21 is pushed further rearward, the bending restriction portion 42 enters the bending space 41. As a result, the elastic deformation of the lance 39 is restricted, and thus the release of the locking structure between the female terminal 45 and the lance 39 can be restricted.
　また、リテーナ２１の前壁４３が耐振リング２０に前方から係止することにより、耐振リング２０が前方への抜け止めされた状態で保持されるようになっている。 Further, by locking the front wall 43 of the retainer 21 to the vibration-proof ring 20 from the front, the vibration-proof ring 20 is held in a state in which it is prevented from slipping forward.
　続いて、雌コネクタ１１と雄コネクタ１２とが嵌合される。雄フード部１３のロック突起１６が、ロックアーム３２の前端部に前方から当接すると、ロックアーム３２の前端部は上方に揺動する。更に雄コネクタ１２が後方に押し込まれると、ロックアーム３２が復帰変形し、ロック突起１６が係止孔３４の内部に嵌入する。これにより、雄コネクタ１２と雌コネクタ１１とが嵌合状態でロックされるようになっている。 Subsequently, the female connector 11 and the male connector 12 are fitted together. When the lock protrusion 16 of the male hood portion 13 comes into contact with the front end portion of the lock arm 32 from the front, the front end portion of the lock arm 32 swings upward. When the male connector 12 is further pushed rearward, the lock arm 32 is deformed by return, and the lock protrusion 16 is fitted into the locking hole 34. As a result, the male connector 12 and the female connector 11 are locked in a fitted state.
　雄端子１５が、雌端子４５の接続筒部２２内に挿入されて、接続筒部２２の内壁と、弾性接触片２６の接点部２７との間に挟まれる。これにより、雄端子１５と雌端子４５とが電気的に接続される。 The male terminal 15 is inserted into the connecting tubular portion 22 of the female terminal 45 and is sandwiched between the inner wall of the connecting tubular portion 22 and the contact portion 27 of the elastic contact piece 26. As a result, the male terminal 15 and the female terminal 45 are electrically connected.
　雄コネクタ１２の雄フード部１３が、雌コネクタ１１の雌フード部３０とタワー部１８との間の隙間に嵌入されると、雄フード部１３の先端部が、液密リング１９の耳部３６に前方から当接する。これにより、雄フード部１３の先端部と雌フード部３０の後端部との間が液密にシールされる。 When the male hood portion 13 of the male connector 12 is fitted into the gap between the female hood portion 30 of the female connector 11 and the tower portion 18, the front end portion of the male hood portion 13 is moved to the ear portion 36 of the liquid-tight ring 19. Abut on from the front. As a result, the front end of the male hood portion 13 and the rear end portion of the female hood portion 30 are liquid-tightly sealed.
　また、雄フード部１３の内面と、液密リング１９の液密リップ３５とが密着することにより、雄フード部１３の内面と液密リング１９との間が液密にシールされる。雄フード部１３の内面によって、液密リング１９が、タワー部１８の径方向の内方に圧縮されるので、液密リング１９の内面がタワー部１８の外面に密着する。これにより、液密リング１９とタワー部１８の外面との間が液密にシールされる。 Further, the inner surface of the male hood portion 13 and the liquid-tight lip 35 of the liquid-tight ring 19 are in close contact with each other, so that the inner surface of the male hood portion 13 and the liquid-tight ring 19 are liquid-tightly sealed. The liquid-tight ring 19 is compressed inward in the radial direction of the tower portion 18 by the inner surface of the male hood portion 13, so that the inner surface of the liquid-tight ring 19 comes into close contact with the outer surface of the tower portion 18. As a result, the liquid-tight ring 19 and the outer surface of the tower portion 18 are liquid-tightly sealed.
　雌コネクタ１１と雄コネクタ１２とが嵌合した状態で、雄フード部１３の内面と、耐振リング２０の耐振リップ３７とが接触することにより、耐振リング２０がタワー部１８に対して押圧される。これにより、耐振リング２０が弾性的に圧縮変形する。この結果、耐振リング２０により、雄フード部１３からタワー部１８へと伝わる振動、および／または、タワー部１８から雄フード部１３へと伝わる振動が吸収される。 When the female connector 11 and the male connector 12 are fitted to each other, the inner surface of the male hood portion 13 and the vibration-proof lip 37 of the vibration-proof ring 20 come into contact with each other, so that the vibration-proof ring 20 is pressed against the tower portion 18. .. As a result, the vibration-proof ring 20 is elastically compressed and deformed. As a result, the vibration resistant ring 20 absorbs the vibration transmitted from the male hood portion 13 to the tower portion 18 and/or the vibration transmitted from the tower portion 18 to the male hood portion 13.
　雄コネクタ１２と雌コネクタ１１との嵌合が完了した状態で、前後方向について、耐振リング２０は、雌端子の接点部２７に対応する位置に配されるようになっている。換言すると、タワー部１８の軸方向（前後方向）について直交すると共に雌端子の接点部２７が含まれる仮想的な面Ｐでコネクタ構成体１０を切断した場合、この仮想的な面Ｐは、耐振リング２０を横切るようになっている。 The vibration-proof ring 20 is arranged at a position corresponding to the contact portion 27 of the female terminal in the front-rear direction in a state where the male connector 12 and the female connector 11 have been fitted together. In other words, when the connector structure 10 is cut along a virtual plane P that is orthogonal to the axial direction (front-back direction) of the tower portion 18 and includes the contact portion 27 of the female terminal, this virtual plane P is vibration resistant. It is designed to cross the ring 20.
＜実施形態２＞
　次に、本明細書に開示された技術の実施形態２に係るコネクタ構成体５４を図９から図１２を参照しつつ説明する。コネクタ構成体５４は、雌コネクタ５０を有する。 <Embodiment 2>
Next, a connector structure 54 according to a second embodiment of the technology disclosed in this specification will be described with reference to FIGS. 9 to 12. The connector structure 54 has a female connector 50.
＜耐振リング２０＞
　耐振リング２０は、液密リング１９の前方の位置において、タワー部１８に外嵌されている。耐振リング２０と液密リング１９とは、前後方向に隙間を有して配されていてもよいし、また、耐振リング２０の後端部と液密リング１９の前端部とが接触していてもよい。 <Vibration resistant ring 20>
The vibration-proof ring 20 is fitted onto the tower portion 18 at a position in front of the liquid-tight ring 19. The vibration-proof ring 20 and the liquid-tight ring 19 may be arranged with a gap in the front-rear direction, or the rear end of the vibration-proof ring 20 and the front end of the liquid-tight ring 19 are in contact with each other. Good.
＜リテーナ５１＞
　リテーナ５１の前壁５２の外縁部には、後方に延びる押え壁５３が形成されている。押え壁５３の後端部は、耐振リング２０の前端部に前方から当接するようになっている。これにより、耐振リング２０をタワー部１８に対して前方に抜け止め状態で保持するようになっている。 <Retainer 51>
A retaining wall 53 extending rearward is formed on an outer edge portion of the front wall 52 of the retainer 51. The rear end portion of the pressing wall 53 comes into contact with the front end portion of the vibration-proof ring 20 from the front. As a result, the vibration-proof ring 20 is retained in the forward direction with respect to the tower portion 18 in a retaining state.
　耐振リング２０がリテーナ５１によって保持された状態で、前後方向について、耐振リング２０はタワー部１８の中央位置付近に配されている。中央位置付近とは、前後方向についてタワー部１８の中央位置に耐振リング２０が配された場合を含むと共に、中央位置でない場合であっても、実質的に中央と認定しうる場合を含む。 With the vibration-proof ring 20 held by the retainer 51, the vibration-proof ring 20 is arranged near the central position of the tower portion 18 in the front-back direction. The vicinity of the center position includes the case where the vibration-proof ring 20 is arranged at the center position of the tower portion 18 in the front-rear direction, and includes the case where it can be substantially recognized as the center even when it is not the center position.
　雄コネクタ１２と雌コネクタ５０との嵌合が完了した状態で、前後方向について、耐振リング２０は、雌端子の接点部２７に対応する位置に配されるようになっている。換言すると、タワー部１８の軸方向（前後方向）について直交すると共に雌端子の接点部２７が含まれる仮想的な面Ｐでコネクタ構成体１０を切断した場合、この仮想的な面Ｐは、耐振リング２０を横切るようになっている。 The vibration-proof ring 20 is arranged at a position corresponding to the contact portion 27 of the female terminal in the front-rear direction when the male connector 12 and the female connector 50 are completely fitted together. In other words, when the connector structure 10 is cut along a virtual plane P that is orthogonal to the axial direction (front-back direction) of the tower portion 18 and includes the contact portion 27 of the female terminal, this virtual plane P is vibration resistant. It is designed to cross the ring 20.
　上記以外の構成については、実施形態１と略同様なので、同一部材については同一符号を付し、重複する説明を省略する。 Since the configuration other than the above is substantially the same as that of the first embodiment, the same reference numerals are given to the same members, and duplicate description will be omitted.
＜実験例＞
　続いて、本明細書に開示された技術の効果を示す実験例について説明する。実験例においては、実施例１、実施例２、比較例１、および比較例２について、コネクタの変位量を測定した。図１３には、比較例１におけるコネクタの変位量を１とした場合の、実施例１、実施例２、および比較例２におけるコネクタの変位量の相対値を示した。曲線Ａは実施例１の実験結果を示し、曲線Ｂは実施例２の実験結果を示し、曲線Ｃは比較例１の実験結果を示し、曲線Ｄは比較例２の実験データを示す。 <Experimental example>
Next, an experimental example showing the effect of the technique disclosed in this specification will be described. In the experimental example, the displacement amount of the connector was measured for Example 1, Example 2, Comparative Example 1, and Comparative Example 2. FIG. 13 shows the relative values of the displacement amounts of the connectors in Example 1, Example 2, and Comparative Example 2 when the displacement amount of the connector in Comparative Example 1 was set to 1. Curve A shows the experimental results of Example 1, curve B shows the experimental results of Example 2, curve C shows the experimental results of Comparative Example 1, and curve D shows the experimental data of Comparative Example 2.
　実施例１に係るコネクタ構成体は、本明細書に記載された実施形態１に係るコネクタ構成体１０である。実施例２に係るコネクタ構成体は、本明細書に記載された実施形態２に係るコネクタ構成体５４である。 The connector structure according to the first embodiment is the connector structure 10 according to the first embodiment described in this specification. The connector structure according to the second example is the connector structure 54 according to the second embodiment described in the present specification.
　図１４に、比較例１に係るコネクタ構成体６０を示す。比較例１に係るリテーナ６３の前壁６４の外縁部には、後方に延びる押え壁６５が形成されている。押え壁６５の後端部は、液密リング１９の前端部に係止している。これにより、液密リング１９は、雌ハウジング２８に対して前方への抜け止め状態で保持されるようになっている。上記以外の構成については、実施形態１と略同様なので、同一部材については同一符号を付し、重複する説明を省略する。 FIG. 14 shows a connector structure 60 according to Comparative Example 1. A retaining wall 65 extending rearward is formed on an outer edge portion of the front wall 64 of the retainer 63 according to Comparative Example 1. The rear end of the pressing wall 65 is locked to the front end of the liquid-tight ring 19. As a result, the liquid-tight ring 19 is retained in the forward direction with respect to the female housing 28. Since the configuration other than the above is substantially the same as that of the first embodiment, the same members are designated by the same reference numerals, and the duplicate description will be omitted.
　図１５に、比較例２に係るコネクタ構成体７０を示す。比較例２に係るリテーナ７１の前端部には、タワー部１８の径方向の外方に突出するリテーナリブ７２が形成されている。リテーナリブ７２は、雄フード部１３の内面に、内方から当接している。これにより、雄コネクタ１２とリテーナ７１との間の共振が抑制されるようになっている。上記以外の構成については、比較例１と略同様なので、同一部材については同一符号を付し、重複する説明を省略する。 FIG. 15 shows a connector structure 70 according to Comparative Example 2. A retainer rib 72 that protrudes outward in the radial direction of the tower portion 18 is formed at the front end portion of the retainer 71 according to Comparative Example 2. The retainer rib 72 is in contact with the inner surface of the male hood portion 13 from the inside. As a result, resonance between the male connector 12 and the retainer 71 is suppressed. Since the configuration other than the above is substantially the same as that of Comparative Example 1, the same members are designated by the same reference numerals, and the duplicated description will be omitted.
　図１６に、コネクタの変位量を測定する測定器８０を示す。測定器８０は、加振器８１と、レーザ変位計８２（株式会社キーエンス，型式ＬＫ－Ｇ１５０）と、制御装置８３とを備えている。加振器８１は、基部８１Ａと、基部８１Ａ上で雄コネクタ１２を支持する第１支持部８１Ｂと、基部８１Ａ上で電線２３の一方の端末部側を支持する第２支持部８１Ｃとを有する。レーザ変位計８２は、加振器８１を動作させた際の雌ハウジング２８の変位を計測する。 FIG. 16 shows a measuring device 80 for measuring the amount of displacement of the connector. The measuring device 80 includes a vibrator 81, a laser displacement meter 82 (Keyence Corporation, model LK-G150), and a controller 83. The vibrator 81 has a base portion 81A, a first support portion 81B that supports the male connector 12 on the base portion 81A, and a second support portion 81C that supports one end portion side of the electric wire 23 on the base portion 81A. .. The laser displacement meter 82 measures the displacement of the female housing 28 when the vibrator 81 is operated.
　制御装置８３は、加振器８１を、５０Ｈｚから２０００Ｈｚの周波数帯で、ＰＳＤ（Ｐｏｗｅｒ　Ｓｐｅｃｔｒａｌ　Ｄｅｎｓｉｔｙ）が一定のランダム振動波で加振させるとともに、レーザ変位計８２からの変位に応じた信号を受けて、雌ハウジング２８の変位を計測する。測定器８０の第１支持部８１Ｂに支持された雄コネクタ１２には、電線２３が接続された雌コネクタ１１が嵌合している。図１３には、２００Ｈｚから１０００Ｈｚ帯を拡大して記載した。 The control device 83 excites the exciter 81 with a random vibration wave having a constant PSD (Power Spectral Density) in a frequency band of 50 Hz to 2000 Hz and receives a signal according to the displacement from the laser displacement meter 82. Then, the displacement of the female housing 28 is measured. The female connector 11 to which the electric wire 23 is connected is fitted to the male connector 12 supported by the first support portion 81B of the measuring instrument 80. In FIG. 13, the range from 200 Hz to 1000 Hz is enlarged and described.
＜結果と考察＞
　比較例１のピーク値を１とした場合において、実施例１のピーク値は０．８であり、実施例２のピーク値は０．７であった。このように、本願明細書に記載された技術によれば、コネクタの変位量を減少させることができる。 <Results and discussion>
When the peak value of Comparative Example 1 was set to 1, the peak value of Example 1 was 0.8 and the peak value of Example 2 was 0.7. As described above, according to the technique described in the present specification, the displacement amount of the connector can be reduced.
　比較例２においてコネクタの変位量がピーク値（０．７）を示す周波数は８５０Ｈｚであった。これに対して、実施例１においてコネクタの変位量がピーク値（０．８）を示す周波数は４７０Ｈｚであり、実施例２においてコネクタの変位量がピーク値（０．７）を示す周波数は４８０Ｈｚであった。このように、実施例１および実施例２においては、コネクタの変位量のピーク値を示す周波数が、比較例２に比べて低くなっていた。また、コネクタの変位量のピーク値については、実施例１および実施例２と、比較例２とは、ほぼ同等であった。 In Comparative Example 2, the frequency at which the displacement amount of the connector showed the peak value (0.7) was 850 Hz. On the other hand, the frequency at which the displacement amount of the connector exhibits the peak value (0.8) in Example 1 is 470 Hz, and the frequency at which the displacement amount of the connector exhibits the peak value (0.7) is 480 Hz. Met. As described above, in Examples 1 and 2, the frequency showing the peak value of the displacement amount of the connector was lower than that in Comparative Example 2. Further, the peak value of the displacement amount of the connector was almost the same in the first and second examples and the second comparative example.
　周波数が低いということは、共振のエネルギーが大きいことを示している。つまり、コネクタの変位量のピーク値が同程度である場合であっても、周波数が低いものは共振のエネルギーが大きく、周波数が高いものは共振のエネルギーが小さい。実施例１および実施例２に係るコネクタは、比較例２に係るコネクタに比べて、より大きな共振のエネルギーを、効果的に減衰させることができる。 ▽ The low frequency means that the resonance energy is high. That is, even if the peak value of the displacement amount of the connector is about the same, the resonance energy is large when the frequency is low, and the resonance energy is small when the frequency is high. The connectors according to Example 1 and Example 2 can effectively attenuate larger resonance energy than the connectors according to Comparative Example 2.
