Abstract

This water-resistant connector (C1) is characterized by having a configuration having: a pair of mutually engageable male/female housings (10, 30); and a synthetic resin sealing plate (50) that is sandwiched between a pair of facing surfaces (16, 35) facing in the engagement direction of the pair of male/female housings (10, 30) and seals between the pair of male/female housings (10, 30). As a result of this configuration, the sealing plate (50): is, as a result of being made of synthetic resin, less likely to deform than if made of rubber; and, as a result of being sandwiched between the pair of facing surfaces (16, 35) of the pair of male/female housings (10, 30), has suppressed positional displacement thereof in the engagement direction. Accordingly, the sealing plate (50) can be held in the normal attachment state. As a result, the pair of male/female housings (10, 30) can be sealed therebetween by causing the sealing plate (50) to come in contact with the pair of facing surfaces (16, 35).

Description

防水コネクタWaterproof connector
 本発明は、防水コネクタに関する。 The present invention relates to a waterproof connector.
 従来、防水コネクタの一例として、特許文献1に記載のものが知られている。このコネクタは、互いに嵌合可能な雄ハウジングと雌ハウジングとを備えている。雌ハウジングは、雌端子を挿入可能な雌キャビティが形成された雌端子収容部と、この雌端子収容部の周りを取り囲む外筒部とを備え、雌端子収容部の外周面にはゴム製のシールリングが嵌着されている。 Conventionally, the thing of patent document 1 is known as an example of a waterproof connector. This connector includes a male housing and a female housing that can be fitted to each other. The female housing includes a female terminal housing portion in which a female cavity into which a female terminal can be inserted is formed, and an outer cylinder portion surrounding the female terminal housing portion, and the outer peripheral surface of the female terminal housing portion is made of rubber. A seal ring is fitted.
 そして、雌雄一対のハウジングを嵌合すると、雄ハウジングのフード部が雌ハウジングのシールリングと外筒部との間に入り込み、シールリングがフード部と雌端子収容部との間に挟圧された状態で密着することで、雌雄一対のハウジング間がシールされる。 When the pair of male and female housings are fitted, the hood portion of the male housing enters between the seal ring and the outer cylinder portion of the female housing, and the seal ring is sandwiched between the hood portion and the female terminal accommodating portion. By closely contacting in a state, a pair of male and female housings is sealed.

 ところで、シールリングは、ゴム製であるから変形しやすい。このため、シールリングが、例えば幅方向の一端側と他端側とが前後にずれるように変形した状態で、雌端子収容部の外周面に嵌着されるおそれがある。また、シールリングが、例えば雄ハウジングと雌ハウジングとの嵌合時にフード部の先端に押され、正規の装着位置よりも後方にずれてしまうおそれもある。シールリングが正規の装着状態(正規の形状および正規の位置)に保持されていないと、防水性の低下を招くおそれがあるため、その対策が望まれていた。 Incidentally, since the seal ring is made of rubber, it is easily deformed. For this reason, there exists a possibility that a seal ring may be fitted by the outer peripheral surface of a female terminal accommodating part in the state deform | transformed so that the one end side and other end side of the width direction may shift | deviate back and forth, for example. Further, the seal ring may be pushed by the tip of the hood portion when the male housing and the female housing are fitted, for example, and may be displaced rearward from the normal mounting position. If the seal ring is not held in a regular wearing state (regular shape and regular position), there is a possibility that the waterproofness may be lowered.
 本発明は上記のような事情に基づいて完成されたものであって、防水性の低下を防ぐことを目的とする。 The present invention has been completed based on the above circumstances, and aims to prevent deterioration of waterproofness.
 本発明の防水コネクタは、互いに嵌合可能な雌雄一対のハウジングと、前記雌雄一対のハウジングにおいて嵌合方向に対向する一対の対向面間に挟持されて前記雌雄一対のハウジング間をシールする合成樹脂製のシール板と、を有する構成としたところに特徴を有する。 The waterproof connector of the present invention includes a pair of male and female housings that can be fitted to each other, and a synthetic resin that is sandwiched between a pair of opposing surfaces facing each other in the fitting direction in the pair of male and female housings to seal between the pair of male and female housings. And a sealing plate made of metal.
 このような構成によると、シール板は合成樹脂製であるから、ゴム製である場合に比して変形しにくく、また、雌雄一対のハウジングの一対の対向面間に挟まれるから、嵌合方向への位置ずれが規制される。したがって、シール板を正規の装着状態に保持することができる。このようにして、シール板を一対の対向面に当接させることにより雌雄一対のハウジング間をシールすることができる。 According to such a configuration, since the seal plate is made of synthetic resin, it is less likely to be deformed than when it is made of rubber, and is sandwiched between a pair of opposing surfaces of a pair of male and female housings. The position shift to is regulated. Therefore, the seal plate can be held in a regular mounting state. In this way, the pair of male and female housings can be sealed by bringing the seal plate into contact with the pair of opposing surfaces.
 本発明の実施の態様として、以下の構成が好ましい。
 前記雌雄一対のハウジングのうち雄ハウジングに保持された雄端子のタブが、雌ハウジング側に突出し、この雌ハウジングに保持された雌端子に接触して雌雄両端子が電気的に接続されるようになっており、前記シール板に、前記タブが貫通する貫通孔が設けられ、この貫通孔の孔縁部に、筒状のシール壁が嵌合方向に突出して設けられており、このシール壁が前記一対の対向面間に挟持される構成としてもよい。
 このような構成によると、シール壁が一対の対向面間に挟持されることで雌雄一対のハウジング間をシールすることができる。

The rear portion of the female cavity 32 is sealed by being closed by a rubber plug 44 attached to the female terminal 40, similarly to the male cavity 13.
 雌キャビティ32の上壁には、雄キャビティ13と同様、挿入途中の雌端子40に押圧されることで上側に弾性変形して撓み空間Sに退避し、かつ雌端子40が正規位置に達すると下側に弾性復帰して雌端子40に係止し、その抜け止めを図る雌ランス33が設けられている。 On the upper wall of the female cavity 32, like the male cavity 13, when it is pressed by the female terminal 40 in the middle of insertion, it is elastically deformed upward and retracts into the bending space S, and when the female terminal 40 reaches the normal position. A female lance 33 is provided which elastically returns to the lower side and engages with the female terminal 40 to prevent it from coming off.
 また、雌端子収容部31の前端面(雄ハウジング10との対向面であって、雌対向面35と称する)には、雄端子20のタブ22を挿通可能な雌挿通孔34が、前後方向に貫通して形成されている。雌挿通孔34の前側部分には、前端へ向かって開口寸法が少しずつ広がるように傾斜する第1案内面36が形成され、雄ハウジング10と雌ハウジング30とを嵌合させる際、雄端子20のタブ22が第1案内面36に前方から当接してその傾斜に案内され、雌挿通孔34に誘い込まれ、ここから雌キャビティ32にスムーズに誘い込まれて雌端子40と接続されるようになっている。 Further, a female insertion hole 34 through which the tab 22 of the male terminal 20 can be inserted is formed in the front end surface of the female terminal accommodating portion 31 (the surface facing the male housing 10 and referred to as the female facing surface 35). It is formed to penetrate through. A first guide surface 36 that is inclined so that the opening size gradually increases toward the front end is formed in the front portion of the female insertion hole 34, and when the male housing 10 and the female housing 30 are fitted, the male terminal 20. The tab 22 is brought into contact with the first guide surface 36 from the front and guided to the inclination, and is guided into the female insertion hole 34, and is smoothly guided into the female cavity 32 from here and connected to the female terminal 40.

Connected.
 さて、防水コネクタCには、嵌合時に両ハウジング10,30間をシールするシール板50が備えられている。シール板50は、雄ハウジング10および雌ハウジング30とは別体に形成されたものであり、両ハウジング10,30の嵌合前においては、雄ハウジング10の雄対向面16に予め装着、保持されている。 The waterproof connector C is provided with a seal plate 50 that seals between the housings 10 and 30 when fitted. The seal plate 50 is formed separately from the male housing 10 and the female housing 30, and is mounted and held in advance on the male facing surface 16 of the male housing 10 before the two housings 10 and 30 are fitted together. ing.
 シール板50は、ゴムよりも硬質の合成樹脂材(例えばポリプロピレンやポリブチレンテレフタレート等)により形成されている。なお、シール板50は、ゴムよりも硬質ではあるものの、両ハウジング10,30に当接してこれらの間をシールできる程度の弾性を有している。 The seal plate 50 is formed of a synthetic resin material (for example, polypropylene or polybutylene terephthalate) that is harder than rubber. Although the seal plate 50 is harder than rubber, the seal plate 50 has enough elasticity to contact the housings 10 and 30 and seal between them.
 シール板50は、雄対向面16に沿う略方形の板状をなすシール本体部51と、シール本体部51から両ハウジング10,30の嵌合方向に突出する一対のシール壁52,53とを備えている。なお、一対のシール壁52,53のうち雄ハウジング10側に突出するシール壁を雄側シール壁52、雌ハウジング30側に突出するシール壁を雌側シール壁53とする。 The seal plate 50 includes a seal main body 51 having a substantially square plate shape along the male facing surface 16 and a pair of seal walls 52 and 53 protruding from the seal main body 51 in the fitting direction of the housings 10 and 30. I have. Of the pair of seal walls 52, 53, the seal wall protruding toward the male housing 10 is referred to as a male side seal wall 52, and the seal wall protruding toward the female housing 30 is referred to as a female side seal wall 53.
 シール本体部51は、雄ハウジング10の雄対向面16(フード部12の奥端面)のほぼ全面を覆う大きさの板状とされている。シール本体部51の中心部には、円形の貫通孔54が横並びに一対形成されている。雄端子20のタブ22は、貫通孔54を貫通して、シール本体部51の前方に突出可能とされている。雄側シール壁52は、貫通孔54の孔縁部から嵌合方向後側に突出する筒状をなし、雌側シール壁53は、貫通孔54の孔縁部から嵌合方向前側に突出する筒状をなしている。 The seal body 51 is a plate having a size that covers almost the entire surface of the male facing surface 16 of the male housing 10 (the back end surface of the hood 12). A pair of circular through holes 54 are formed side by side at the center of the seal body 51. The tab 22 of the male terminal 20 can pass through the through hole 54 and protrude forward of the seal body 51. The male side seal wall 52 has a cylindrical shape protruding from the hole edge of the through hole 54 to the rear side in the fitting direction, and the female side seal wall 53 protrudes from the hole edge of the through hole 54 to the front side in the fitting direction. It has a cylindrical shape.
 貫通孔54は、第1案内面36の前端における開口寸法(最大開口寸法)よりも小さく、かつ、第1案内面36の後端における開口寸法(最小開口寸法)よりも大きめの開口寸法を有している。同様に、貫通孔54は、第2案内面17の前端における開口寸法(最大開口寸法)よりも小さく、かつ、第2案内面17の後端における開口寸法(最小開口寸法)よりも大きめの開口寸法を有している。 The through hole 54 has an opening size smaller than the opening size (maximum opening size) at the front end of the first guide surface 36 and larger than the opening size (minimum opening size) at the rear end of the first guide surface 36. is doing. Similarly, the through hole 54 is smaller than the opening size (maximum opening size) at the front end of the second guide surface 17 and larger than the opening size (minimum opening size) at the rear end of the second guide surface 17. Have dimensions.
 各シール壁52,53は、シール本体部51を中心として対称に形成されている。また、各シール壁52,53の内周面は、貫通孔54の内周面と面一をなして嵌合方向に延びる形態とされている。一方、各シール壁52,53の外周面は、シール本体部51から離れるほど貫通孔54の軸心側に近づくテーパ状に形成されている。さらに、シール板50が各対向面16,35の間に挟持されると、雄側シール壁52の外周面は、第1案内面36に全周に亘って当接し、雌側シール壁53の外周面は、第2案内面17に全周に亘って当接するようになっている。これにより、雌ハウジング30とシール板50との間がシールされ、雄ハウジング10とシール板50との間がシールされることになる。したがって、雄キャビティ13、雄挿通孔15、貫通孔54、雌挿通孔34、および雌キャビティ32に亘る空間は、止水された空間となる。 The seal walls 52 and 53 are formed symmetrically about the seal body 51. Further, the inner peripheral surfaces of the seal walls 52 and 53 are configured to be flush with the inner peripheral surface of the through hole 54 and extend in the fitting direction. On the other hand, the outer peripheral surfaces of the seal walls 52 and 53 are formed in a tapered shape that approaches the axial center side of the through hole 54 as the distance from the seal body 51 increases. Further, when the seal plate 50 is sandwiched between the opposing surfaces 16 and 35, the outer peripheral surface of the male side seal wall 52 contacts the first guide surface 36 over the entire periphery, and the female side seal wall 53 The outer peripheral surface is in contact with the second guide surface 17 over the entire periphery. As a result, the space between the female housing 30 and the seal plate 50 is sealed, and the space between the male housing 10 and the seal plate 50 is sealed. Therefore, the space spanning the male cavity 13, the male insertion hole 15, the through hole 54, the female insertion hole 34, and the female cavity 32 is a water-stopped space.
 シール本体部51の外周には、図4に示すように、複数の保持リブ55が形成されている。これらの保持リブ55は、各辺に2個ずつ4辺にそれぞれ配され、シール本体部51の外周においてほぼ等間隔で配されている。したがって、シール板50をフード部12の内部に装着した際、各保持リブ55がフード部12の内周面に当接するため、シール板50をフード部12の内部に保持させることができる。 A plurality of holding ribs 55 are formed on the outer periphery of the seal body 51 as shown in FIG. These holding ribs 55 are arranged on four sides, two on each side, and are arranged at substantially equal intervals on the outer periphery of the seal body 51. Therefore, when the seal plate 50 is mounted inside the hood portion 12, each holding rib 55 comes into contact with the inner peripheral surface of the hood portion 12, so that the seal plate 50 can be held inside the hood portion 12.
 次に、雄ハウジング10と雌ハウジング30との嵌合方法の一例を説明する。まず、図1に示すように、両ハウジング10,30の嵌合に先立って、雄ハウジング10のフード部12の内部にシール板50を装着する。シール板50をフード部12内に押し込むと、シール板50は、単体時の形状を保ったままフード部12内を移動し、やがて雄側シール壁52が、図2に示すように、第2案内面17に当接する。また、各保持リブ55がフード部12の内周面にほぼ等間隔で当接した状態となる。こうして、雄ハウジング10へのシール板50の装着が完了する。このとき、シール本体部51の各貫通孔54,54は、各雄挿通孔15,15と同軸に配され、また、雄側シール壁52は、全周に亘って第2案内面17に当接した状態になる。 Next, an example of a method for fitting the male housing 10 and the female housing 30 will be described. First, as shown in FIG. 1, the seal plate 50 is mounted inside the hood portion 12 of the male housing 10 prior to the fitting of the housings 10 and 30. When the seal plate 50 is pushed into the hood portion 12, the seal plate 50 moves within the hood portion 12 while maintaining its shape as a single unit, and the male side seal wall 52 eventually becomes the second as shown in FIG. It abuts on the guide surface 17. Further, the holding ribs 55 are in contact with the inner peripheral surface of the hood portion 12 at substantially equal intervals. Thus, the mounting of the seal plate 50 on the male housing 10 is completed. At this time, the through holes 54 and 54 of the seal body 51 are arranged coaxially with the male insertion holes 15 and 15, and the male side seal wall 52 contacts the second guide surface 17 over the entire circumference. It will be in contact.
 次に、雌ハウジング30を、雄ハウジング10のフード部12内に押し込むと、第1案内面36が雌側シール壁53に当接するとともに、両ハウジング10,30が正規の嵌合状態に至り、各端子20,40が正規の接続状態になると同時に、嵌合途中ではロック受け部18を乗り越えるべく撓み変形していたロックアーム37が、ロック受け部18を乗り越えて弾性復帰し、両ハウジング10,30が正規の嵌合状態にロックされる。 Next, when the female housing 30 is pushed into the hood portion 12 of the male housing 10, the first guide surface 36 comes into contact with the female-side seal wall 53, and both the housings 10 and 30 are brought into a normal fitting state. At the same time that the terminals 20 and 40 are properly connected, the lock arm 37, which has been bent and deformed so as to get over the lock receiving portion 18 in the middle of the fitting, moves over the lock receiving portion 18 and elastically recovers. 30 is locked in a proper fitting state.
 両ハウジング10,30の正規の嵌合状態では、雌側シール壁53が第1案内面36に全周に亘って当接し、雄側シール壁52が第2案内面17に全周に亘って当接した状態になる。こうして、両ハウジング10,30の正規の嵌合状態では、雄ハウジング10とシール板50との間、およびシール板50と雌ハウジング30との間がシールされ、もって両ハウジング10,30間がシールされる。 In a properly fitted state of both housings 10, 30, the female-side seal wall 53 contacts the first guide surface 36 over the entire periphery, and the male-side seal wall 52 extends over the entire periphery of the second guide surface 17. It comes into contact. In this way, in the normal fitting state of both the housings 10 and 30, the space between the male housing 10 and the seal plate 50 and the space between the seal plate 50 and the female housing 30 are sealed, so that the space between both the housings 10 and 30 is sealed. Is done.
 以上のように本実施形態では、ゴムよりも硬い合成樹脂製のシール板50を用いて両ハウジング10,30間をシールしているから、シール板50の位置ずれや変形をなくすことができ、シール部材の位置ずれや変形に伴う防水性の低下を防止できる。これにより、両ハウジング10,30間を確実にシールすることができる。また、シール板50を予めフード部12の内部に保持させておくことができるため、両ハウジング10,30の嵌合作業がしやすい。また、シール板50の各シール壁52,53を各案内面17,36に当接させてシール板50を挟持するようにしたため、シール本体部51を各対向面16,35に当接させてシール板50を挟持するよりも強い接圧でシールすることができる。 As described above, in the present embodiment, the seal plate 50 made of a synthetic resin harder than rubber is used to seal between the housings 10 and 30, so that the positional deviation and deformation of the seal plate 50 can be eliminated. It is possible to prevent a decrease in waterproofness due to the displacement or deformation of the seal member. Thereby, between both the housings 10 and 30 can be sealed reliably. In addition, since the seal plate 50 can be held in the hood portion 12 in advance, it is easy to fit the housings 10 and 30 together. Further, since the seal walls 52 and 53 of the seal plate 50 are brought into contact with the guide surfaces 17 and 36 to sandwich the seal plate 50, the seal body 51 is brought into contact with the opposing surfaces 16 and 35. Sealing can be performed with a stronger contact pressure than when the sealing plate 50 is sandwiched.

An outer peripheral seal wall 65 and the like are provided.
 各シール壁62,63の外周面は、シール本体部61から離れるほど貫通孔64の軸心側に近づくテーパ状に形成されている。一方、各シール壁62,63の内周面は、シール本体部61から離れるほど貫通孔64の軸心から遠ざかるテーパ状に形成されている。このうち、雄側シール壁62の内周面は、雄端子20のタブ22を貫通孔64に誘い込む第3案内面66とされている。 The outer peripheral surfaces of the seal walls 62 and 63 are formed in a tapered shape that approaches the axial center side of the through hole 64 as the distance from the seal body 61 increases. On the other hand, the inner peripheral surfaces of the seal walls 62 and 63 are formed in a tapered shape that is farther away from the axis of the through hole 64 as the distance from the seal body 61 increases. Among these, the inner peripheral surface of the male-side seal wall 62 is a third guide surface 66 that guides the tab 22 of the male terminal 20 into the through hole 64.
 外周シール壁65は、雌側シール壁63よりも嵌合方向後側に突出している。外周シール壁65の内周面における前端部はシール本体部61の後面(雌対向面35と対向する面)に連結されている一方、外周シール壁65の内周面における後端部には、リップ67が周設されている。このリップ67は断面半円状をなし、径方向内側に突出している。 The outer peripheral seal wall 65 protrudes rearward in the fitting direction from the female side seal wall 63. The front end portion of the inner peripheral surface of the outer peripheral seal wall 65 is connected to the rear surface of the seal body portion 61 (the surface facing the female facing surface 35), while the rear end portion of the inner peripheral surface of the outer peripheral seal wall 65 is A lip 67 is provided around. The lip 67 has a semicircular cross section and projects radially inward.
 雌対向面35には、シール溝39が嵌合方向前側に開口する形態で周設されている。このシール溝39は、雌挿通孔34を中心としてその周囲に環状に設けられている。外周シール壁65は、シール溝39に差し込み可能に環状に設けられている。外周シール壁65がシール溝39に差し込まれると、外周シール壁65のリップ67は、シール溝39を構成する周面に対して全周に亘って当接する。これにより、シール板60と雌ハウジング30の間がシールされる。 A seal groove 39 is provided on the female facing surface 35 so as to open to the front side in the fitting direction. The seal groove 39 is annularly provided around the female insertion hole 34 as a center. The outer peripheral seal wall 65 is provided in an annular shape so that it can be inserted into the seal groove 39.
