<請求項1の発明>
複数の貫通孔を有するゴム栓において、電線が貫通方向に対して斜め方向へ引っ張られたときに貫通孔が拡径し易いのは、貫通孔の周りの径方向の肉が厚くて弾性変形可能な領域が大きいことが原因であると考えられる。そこで、本発明は、ゴム栓に、隣接する貫通孔の間を仕切る仕切壁を有する補強部材を設けた。これにより、各貫通孔の周りの径方向における弾性変形可能な領域が狭められるので、貫通孔が拡径変形し難くなり、貫通孔の拡径変形に起因する防水性能の低下を回避することができる。また、補強部材の係止部をハウジングに係止させることにより、ゴム栓と補強部材をハウジングに対して組み付け状態に保持することができる。
<Invention of Claim 1 >
In rubber plugs with multiple through holes, the diameter of the through hole is easy to expand when the wire is pulled obliquely with respect to the through direction. This is considered to be caused by a large area. Therefore, according to the present invention, the rubber plug is provided with a reinforcing member having a partition wall that partitions between adjacent through holes. This narrows the elastically deformable region in the radial direction around each through-hole, making it difficult for the through-hole to undergo a diameter expansion deformation and avoiding a decrease in waterproof performance due to the diameter expansion deformation of the through-hole. it can. Further, by locking the locking portion of the reinforcing member to the housing, the rubber plug and the reinforcing member can be held in the assembled state with respect to the housing.

以下、本発明を具体化した実施形態1を図1乃至図4を参照して説明する。本実施形態のコネクタは、ハウジング10とゴム栓20と端子金具40とを備えて構成されている。
<Embodiment 1>
A first embodiment of the present invention will be described below with reference to FIGS. 1 to 4. The connector according to this embodiment includes a housing 10, a rubber plug 20, and a terminal fitting 40.

ハウジング10は、合成樹脂製であり、全体としてブロック状をなす。ハウジング10内における後端部を除いた領域には、前後方向に貫通する複数(本実施形態では8つであるが、7つ以下又は9つ以上であってもよい)のキャビティ11が形成されている。複数のキャビティ11は、上下二段に分かれ、縦方向(上下方向)及び横方向(左右方向)に整列して配置されている。各キャビティ11内には、その下面壁に沿って前方へ片持ち状に延出する形態のランス12が形成されている。また、各キャビティ11の前端部には、ハウジング10の前端面に開口する端子挿入口13が形成されており、キャビティ11の前面壁における端子挿入口13の開口縁部は、前止まり面14となっている。   The housing 10 is made of a synthetic resin and has a block shape as a whole. A plurality of cavities 11 penetrating in the front-rear direction (eight in the present embodiment, but may be seven or less or nine or more) may be formed in a region excluding the rear end portion in the housing 10. ing. The plurality of cavities 11 are divided into upper and lower stages, and are arranged in the vertical direction (up and down direction) and the horizontal direction (left and right direction). A lance 12 is formed in each cavity 11 so as to extend forward in a cantilevered manner along its lower wall. Further, a terminal insertion port 13 that opens to the front end surface of the housing 10 is formed at the front end portion of each cavity 11, and the opening edge portion of the terminal insertion port 13 on the front wall of the cavity 11 is connected to the front stop surface 14. It has become.

ハウジング10内の後端部には、ハウジング10の後端面に大きく略方形に開放された形態の収容空間15が形成されている。収容空間15の奥端面(前端面)には、全てのキャビティ11の後端が開口されている。また、収容空間15の内周面は、四隅が四半円弧状に形成された略方形のシール面16となっている。さらに、収容空間15の前端部、即ちシール面16よりも前方(奥方)の位置には、その上下左右の4面を局部的に凹ませた形態の受け部17が形成されている。受け部17は、上下両面における幅方向(左右方向)中央位置と、左右両側面における上下方向中央位置の4カ所に配置されている。尚、図1において、左右両面に形成されている受け部17の図示は、省略している。また、ハウジング10の外面、キャビティ11及び収容空間15等、受け部17以外の部分は、前方及び後方へ移動する金型(図示せず)によって形成されるが、受け部17に関しては、収容空間15内において上下左右に移動するスライド型(図示せず)を用いて成形される。   In the rear end portion of the housing 10, an accommodation space 15 is formed on the rear end surface of the housing 10 so as to be opened in a substantially rectangular shape. The rear ends of all the cavities 11 are opened at the back end surface (front end surface) of the accommodation space 15. Further, the inner peripheral surface of the accommodation space 15 is a substantially rectangular sealing surface 16 having four corners formed in a semicircular arc shape. Further, a receiving portion 17 having a shape in which four upper, lower, left, and right surfaces are locally recessed is formed at a front end portion of the accommodating space 15, that is, a position forward (backward) from the seal surface 16. The receiving part 17 is arrange | positioned at four places of the width direction (left-right direction) center position in upper and lower both surfaces, and the vertical direction center position in both right-and-left both sides. In FIG. 1, illustration of the receiving portions 17 formed on both the left and right sides is omitted. Further, the outer surface of the housing 10, the cavity 11, the accommodation space 15, and other parts other than the receiving portion 17 are formed by a mold (not shown) that moves forward and rearward. 15 is formed using a slide mold (not shown) that moves vertically and horizontally.

収容空間15内には、いわゆる一括タイプのゴム栓20が収容されている。ゴム栓20は、全体としてブロック状をなし、ごの外周には、外周リップ部21が前後方向に複数並んで形成されている。ゴム栓20には、前後方向に貫通する複数(キャビティ11と同数)の貫通孔22が形成されている。貫通孔22は、キャビティ11と対応するように上下左右に整列して配置されており、その横断面形状(貫通孔22の貫通方向と直角な断面形状)は円形をなしている。各貫通孔22の内周には、周方向に延びる同心円環状をなす内周リップ部23が、軸線方向(貫通方向)に複数並んで形成されている。   In the accommodation space 15, a so-called batch type rubber stopper 20 is accommodated. The rubber plug 20 has a block shape as a whole, and a plurality of outer peripheral lip portions 21 are formed on the outer periphery of the rubber stopper 20 in the front-rear direction. The rubber plug 20 has a plurality of through holes 22 (the same number as the cavities 11) penetrating in the front-rear direction. The through-holes 22 are arranged vertically and horizontally so as to correspond to the cavity 11, and the cross-sectional shape (a cross-sectional shape perpendicular to the through-direction of the through-hole 22) is circular. A plurality of inner peripheral lip portions 23 having a concentric annular shape extending in the circumferential direction are formed in the inner circumference of each through-hole 22 side by side in the axial direction (through direction).

このゴム栓20には、補強部材30が一体に設けられている。補強部材30は、比較的剛性の高い合成樹脂製であって、平板状の上面板31、平板状の下面板32、平板状の左右両側面板33、平板状の水平仕切壁34、及び平板状の垂直仕切壁35とを一体に形成した形態となっている。上面板31、下面板32及び左右両側面板33によって、方形の枠部36が構成されており、水平仕切壁34は、左右両側面板33の間に上下両面板31,32と平行に差し渡され、複数の垂直仕切壁35は、左右両側面板33と平行に且つ水平仕切壁34を直角に横切るように上下両面板31,32の間に差し渡されている。   The rubber plug 20 is integrally provided with a reinforcing member 30. The reinforcing member 30 is made of a synthetic resin having a relatively high rigidity, and includes a flat upper plate 31, a flat lower plate 32, left and right flat plates 33, a flat horizontal partition wall 34, and a flat plate. The vertical partition wall 35 is integrally formed. The upper surface plate 31, the lower surface plate 32, and the left and right side surface plates 33 form a rectangular frame portion 36, and the horizontal partition wall 34 is interposed between the left and right side surface plates 33 in parallel with the upper and lower side surface plates 31, 32. The plurality of vertical partition walls 35 are interposed between the upper and lower double-side plates 31 and 32 so as to be parallel to the left and right side surface plates 33 and to cross the horizontal partition wall 34 at a right angle.

かかる補強部材30は、その前端部を除いた大部分がゴム栓20内に埋設されている。埋設する手段としては、成形済みの補強部材30を、モールド金型(図示せず)内にセットし、このモールド金型内でゴム栓20をモールド成形する方法がとられている。つまり、ゴム栓20と補強部材30は二色成形によって一体化されている。補強部材30のうち、枠部36は、全ての貫通孔22の形成領域を一括して包囲するように、換言するとゴム栓20の外周面に沿うように配置されている。また、水平仕切壁34は、上下二段の貫通孔22の間を仕切るように配置され、垂直仕切壁35は、左右に隣り合う貫通孔22の間を仕切るように配置されている。尚、補強部材30の後端は、ゴム栓20の後端面よりも少し前方に位置している。   Most of the reinforcing member 30 excluding its front end is embedded in the rubber plug 20. As a means for embedding, a method is adopted in which a molded reinforcing member 30 is set in a mold (not shown) and the rubber plug 20 is molded in the mold. That is, the rubber plug 20 and the reinforcing member 30 are integrated by two-color molding. Of the reinforcing member 30, the frame portion 36 is disposed so as to surround all the formation regions of the through holes 22, in other words, along the outer peripheral surface of the rubber plug 20. The horizontal partition wall 34 is disposed so as to partition between the upper and lower two-stage through holes 22, and the vertical partition wall 35 is disposed so as to partition between the left and right adjacent through holes 22. Note that the rear end of the reinforcing member 30 is positioned slightly forward of the rear end surface of the rubber plug 20.

さらに、補強部材30の前端部、即ちゴム栓20の前端面から前方へ突出した部分には、外面から突出する形態の4つの係止部37が形成されている。係止部37は、上面板31の幅方向中央位置と、下面板32の幅方向中央位置と、左右両側面板33の上下方向中央位置に配置されている。換言すると、係止部37は、水平仕切壁34の延長線上、及び幅方向中央に位置する垂直仕切壁35の延長線上に配置されている。各係止部37の前面は、前後方向(ハウジング10に対するゴム栓20の組付け方向)に対して傾斜したガイド面37Fとなっており、係止部37の後面は、前後方向に対して直角な係止面37Rとなっている。   Further, four engaging portions 37 are formed on the front end portion of the reinforcing member 30, that is, the portion protruding forward from the front end surface of the rubber plug 20 so as to protrude from the outer surface. The locking portion 37 is arranged at the center position in the width direction of the upper surface plate 31, the center position in the width direction of the lower surface plate 32, and the center position in the vertical direction of the left and right side surface plates 33. In other words, the locking portion 37 is disposed on the extension line of the horizontal partition wall 34 and on the extension line of the vertical partition wall 35 located at the center in the width direction. The front surface of each locking portion 37 is a guide surface 37F inclined with respect to the front-rear direction (the direction in which the rubber plug 20 is assembled to the housing 10), and the rear surface of the locking portion 37 is perpendicular to the front-rear direction. This is a locking surface 37R.

端子金具40は、電線Wの前端部に接続されている。端子金具40は、全体として前後方向に細長い雌形をなすものであって、端子金具40の略前半部分は箱形をなす端子接続部41となっており、他の略後半部分はオープンバレル状の圧着部42となっている。端子接続部41の下面には、係止孔43が形成され、圧着部42には電線Wの前端部が圧着により導通可能に接続されている。接続された電線Wは、端子金具40の後端から、端子金具40に対してほぼ一直線状をなすように後方へ延出した状態となっている。   The terminal fitting 40 is connected to the front end portion of the electric wire W. The terminal fitting 40 has a female shape that is elongated in the front-rear direction as a whole. The substantially first half of the terminal fitting 40 is a box-shaped terminal connecting portion 41, and the other substantially latter half is an open barrel shape. The crimping part 42 is formed. A locking hole 43 is formed on the lower surface of the terminal connecting portion 41, and the front end portion of the electric wire W is connected to the crimping portion 42 so as to be conductive by crimping. The connected electric wire W is in a state of extending backward from the rear end of the terminal fitting 40 so as to be substantially straight with respect to the terminal fitting 40.

次に、本実施形態のコネクタの組付け手順を説明する。
まず、補強部材30が一体化されているゴム栓20を、後方から収容空間15内に組み付ける。組付け状態では、補強部材30の前端が収容空間15の奥端面周縁部に突き当たることで、ゴム栓20が前止まり(それ以上、ハウジング10に対して前方へ相対移動することを規制)されるとともに、各係止部37が対応する受け部17内に嵌入して係止面37Rを受け部17の後面に係止されることで、ゴム栓20がハウジング10に対して後方へ相対移動すること(収容空間15から外れること)が規制され、もって、ゴム栓20と補強部材30がハウジング10に対して組付け状態に保持される。ゴム栓20を組み付けた状態では、ゴム栓20の外周リップ部21が収容空間15のシール面16に対して弾性的に密着し、これにより、ゴム栓20の外周と収容空間15の内周との隙間からハウジング10内に浸水することが規制される。
Next, a procedure for assembling the connector of this embodiment will be described.
First, the rubber plug 20 in which the reinforcing member 30 is integrated is assembled into the accommodation space 15 from the rear. In the assembled state, the front end of the reinforcing member 30 abuts against the peripheral edge of the back end surface of the accommodation space 15, so that the rubber plug 20 is stopped in front (moreover, it is restricted from moving forward relative to the housing 10). At the same time, each of the locking portions 37 is fitted into the corresponding receiving portion 17 and is locked to the rear surface of the receiving portion 17 so that the rubber plug 20 moves rearward relative to the housing 10. That is, the rubber plug 20 and the reinforcing member 30 are held in the assembled state with respect to the housing 10. In the state where the rubber plug 20 is assembled, the outer peripheral lip portion 21 of the rubber plug 20 is elastically in close contact with the seal surface 16 of the storage space 15, whereby the outer periphery of the rubber plug 20 and the inner periphery of the storage space 15. Infiltration into the housing 10 through the gap is restricted.

ゴム栓20を組み付けた後、ハウジング10内に端子金具40を挿入する。挿入に際しては、まず、ゴム栓20の後方から端子金具40の前端部を貫通孔22内に差し込み、貫通孔22が拡径するようにゴム栓20を変形させつつ端子金具40の挿入を進める。そして、端子金具40の全体が貫通孔22を通過し終わると、貫通孔22が元寸法に縮径変形する。また、端子金具40がキャビティ11内に進入する過程では、端子接続部41の下面がランス12を下方へ弾性撓みさせるが、端子金具40が正規の挿入位置まで挿入されると、端子金具40の前端が前止まり面14に突き当たることによって、端子金具40のそれ以上の挿入動作が規制されるとともに、弾性復帰したランス12が係止孔43に係止することにより、端子金具40の後方(抜け方向)への移動が規制され、もって、端子金具40が正規の挿入位置に保持される。   After the rubber plug 20 is assembled, the terminal fitting 40 is inserted into the housing 10. At the time of insertion, first, the front end portion of the terminal fitting 40 is inserted into the through hole 22 from the rear of the rubber plug 20, and the insertion of the terminal fitting 40 is advanced while the rubber plug 20 is deformed so that the diameter of the through hole 22 is increased. And when the whole terminal metal fitting 40 finishes passing through the through-hole 22, the through-hole 22 is reduced in diameter to the original dimension. Further, in the process in which the terminal fitting 40 enters the cavity 11, the lower surface of the terminal connecting portion 41 elastically deflects the lance 12 downward. However, when the terminal fitting 40 is inserted to the proper insertion position, When the front end abuts against the front stop surface 14, further insertion operation of the terminal fitting 40 is restricted, and the elastically restored lance 12 is locked in the locking hole 43, so that Movement in the direction) is restricted, so that the terminal fitting 40 is held in the proper insertion position.

端子金具40が正規挿入されると、端子金具40から後方へ延出している電線Wが貫通孔22を貫通した状態となり、電線Wの外周に内周リップ部23が弾性的に密着する。これにより、電線Wの外周と貫通孔22の内周との隙間を通ってハウジング10内に浸水することが規制される。   When the terminal fitting 40 is properly inserted, the electric wire W extending backward from the terminal fitting 40 enters the through hole 22, and the inner peripheral lip portion 23 is elastically adhered to the outer periphery of the electric wire W. As a result, it is regulated that the water is immersed in the housing 10 through the gap between the outer periphery of the electric wire W and the inner periphery of the through hole 22.

本実施形態のように複数の貫通孔22を有するゴム栓20においては、貫通孔22を貫通してゴム栓20から後方へ延出されている電線Wが、貫通方向に対して上下方向あるいは左右方向へ斜めに引っ張られたときに貫通孔22が拡径し、その結果、貫通孔22の内周と電線Wの外周との間に隙間が空き、この隙間からハウジング10内に浸水することが懸念されるのであるが、この貫通孔22の拡径変形は、貫通孔22の周りの径方向の肉が厚くて弾性変形可能な領域が大きいことが原因であると考えられる。
そこで、本実施形態は、ゴム栓20に、隣接する貫通孔22の間を仕切る水平仕切壁34及び垂直仕切壁35を有する補強部材30を設けた。これにより、各貫通孔22の周りの径方向における弾性変形可能な領域が狭められるので、貫通孔22が拡径変形し難くなり、貫通孔22の拡径変形に起因する防水性能の低下を回避することができる。
In the rubber plug 20 having the plurality of through holes 22 as in the present embodiment, the electric wire W that penetrates the through hole 22 and extends rearward from the rubber plug 20 extends in the vertical direction or the left and right directions with respect to the through direction. When it is pulled obliquely in the direction, the diameter of the through hole 22 increases, and as a result, there is a gap between the inner periphery of the through hole 22 and the outer periphery of the electric wire W, and water can be immersed in the housing 10 from this gap. Although it is a concern, this diameter expansion deformation of the through hole 22 is considered to be caused by a large area in which the radial thickness around the through hole 22 is thick and elastically deformable.
Therefore, in the present embodiment, the rubber plug 20 is provided with the reinforcing member 30 having the horizontal partition wall 34 and the vertical partition wall 35 that partition between the adjacent through holes 22. As a result, the elastically deformable region in the radial direction around each through-hole 22 is narrowed, so that the through-hole 22 is difficult to be expanded and deformed, and a decrease in waterproof performance due to the expanded deformation of the through-hole 22 is avoided. can do.

また、二色成形によって補強部材30とゴム栓20を一体化したので、補強部材30がゴム栓20から離脱することがない。
また、補強部材30に設けた係止部37をハウジング10の受け部17に係止させるようにしたので、ゴム栓20と補強部材30は、ハウジング10に対して離脱規制され、組み付け状態に確実に保持されるようになっている。
Further, since the reinforcing member 30 and the rubber plug 20 are integrated by two-color molding, the reinforcing member 30 will not be detached from the rubber plug 20.
Further, since the locking portion 37 provided on the reinforcing member 30 is locked to the receiving portion 17 of the housing 10, the rubber plug 20 and the reinforcing member 30 are restricted from being detached from the housing 10, and the assembled state is ensured. Is supposed to be retained.
