Each outer peripheral lip 42 is configured with the same height dimension, and the protruding ends thereof are arranged at the same height position. When the rubber plug 40 is inserted into the mounting hole 17, the outer peripheral lip 42 is elastically brought into close contact with the inner peripheral surface of the mounting hole 17, thereby sealing the housing 10.

また、ゴム栓40における貫通孔41の内周面には、前後方向に間隔をあけて複数条、図示する場合は3条の内周リップ43が突出して形成されている。各内周リップ43は、各外周リップ42とほぼ同一の位相であって、各外周リップ42の突出寸法よりも小さい突出寸法を有している。電線30が各貫通孔41に挿入されたとき、各内周リップ43が電線30の外周面に弾性的に密着され、これによって電線30との間のシールがとられる。   In addition, a plurality of inner circumferential lips 43 protruding in the front-rear direction are formed on the inner circumferential surface of the through-hole 41 in the rubber plug 40, and in the illustrated case, three inner circumferential lips 43 are projected. Each inner peripheral lip 43 is in the same phase as each outer peripheral lip 42 and has a protruding dimension smaller than the protruding dimension of each outer peripheral lip 42. When the electric wire 30 is inserted into each through-hole 41, each inner peripheral lip 43 is elastically brought into close contact with the outer peripheral surface of the electric wire 30, and thereby a seal with the electric wire 30 is taken.

各内周リップ43のうち、最前方(端子金具80の貫通孔41への挿通方向出口側)及び最後方(端子金具80の貫通孔41への挿通方向入り口側)に位置する2条の内周リップ43Aは、両者間となる中央に位置する1条の内周リップ43Bとは異形状とされている。具体的には、中央の内周リップ43Bの開口形状(内周面の断面形状)は、ここに挿入される電線30の絶縁被覆の外周面に沿った真円形状とされている一方、前後2条の内周リップ43Aの開口形状は、ここに挿通される端子金具80の接続部81の最大寸法部分と対応する高さ方向(長さ方向)に長い長円形状(長孔状)とされている。より具体的には、前後2条の内周リップ43Aの内周面における幅寸法は中央の内周リップ43Bの内周面における幅寸法よりも小さく、前後2条の内周リップ43Aの内周面における高さ寸法は中央の内周リップ43Bの内周面における高さ寸法よりも大きくされている。端的には、前後2条の内周リップ43Aは真円形を幅方向に押し潰した形態とされている。なお、ゴム栓40全体は中央の内周リップ43Bを挟んで前後に対称な形状をなしている。   Among the inner peripheral lips 43, the innermost of the two strips located at the forefront (exit side in the insertion direction of the terminal fitting 80 into the through hole 41) and the rearmost (entrance side in the insertion direction of the terminal fitting 80 into the through hole 41) The circumferential lip 43A has a different shape from the single inner circumferential lip 43B located at the center between them. Specifically, the opening shape (cross-sectional shape of the inner peripheral surface) of the central inner peripheral lip 43B is a perfect circle shape along the outer peripheral surface of the insulating coating of the electric wire 30 inserted therein, while The opening shape of the two inner peripheral lips 43A is an oval shape (long hole shape) that is long in the height direction (length direction) corresponding to the maximum dimension portion of the connection portion 81 of the terminal fitting 80 inserted therethrough. Has been. More specifically, the width of the inner peripheral lip 43A of the two front and rear inner lips 43A is smaller than the width of the inner peripheral lip 43B of the central inner lip 43B. The height dimension on the surface is made larger than the height dimension on the inner peripheral surface of the central inner peripheral lip 43B. In short, the front and rear two inner peripheral lips 43A are formed by crushing a true circle in the width direction. The rubber plug 40 as a whole has a symmetrical shape in the front-rear direction with the inner peripheral lip 43B in the center.

また、ゴム栓40の前後両面に開口する貫通孔41の開口縁部には、端子金具80の貫通孔41への挿入案内をなす前後一対の案内面44がテーパ状に拡開して形成されている。両案内面44は、前後両方の内周リップ43Aの内周面から連続して高さ方向に長い円環状をなしている。   In addition, a pair of front and rear guide surfaces 44 that guide insertion into the through hole 41 of the terminal fitting 80 is formed in a taper shape at the opening edge portion of the through hole 41 that opens on both front and rear surfaces of the rubber plug 40. ing. Both guide surfaces 44 form an annular shape that is long in the height direction continuously from the inner peripheral surfaces of both the front and rear inner peripheral lips 43A.

ハウジング10の装着孔17には、ゴム栓40の挿入後、リアホルダ60が挿入され、これによってゴム栓40の後方への抜け止めなされる。リアホルダ60は合成樹脂製であって、ゴム栓40よりも小さい厚みをもって構成されている。リアホルダ60には、各貫通孔41と同軸の位置に、電線30が遊嵌状態で挿入される複数の遊挿孔61が貫通して形成されている。各遊挿孔61は、端子金具80の接続部81がほぼ適合して挿通可能な形状をなし、スタビライザ87と対応する位置にスタビライザ87を嵌合状態で受ける受け孔62を有している。   The rear holder 60 is inserted into the mounting hole 17 of the housing 10 after the rubber plug 40 is inserted, thereby preventing the rubber plug 40 from coming off backward. The rear holder 60 is made of a synthetic resin and has a thickness smaller than that of the rubber plug 40. The rear holder 60 is formed with a plurality of loose insertion holes 61 through which the electric wires 30 are inserted in a loosely fitted state at positions coaxial with the through holes 41. Each loose insertion hole 61 has a shape in which the connection portion 81 of the terminal fitting 80 is substantially fitted and can be inserted, and has a receiving hole 62 that receives the stabilizer 87 in a fitted state at a position corresponding to the stabilizer 87.

次に、本実施形態の作用を説明する。
ハウジング10の装着孔17内に後方からゴム栓40及びリアホルダ60を順次挿入する。すると、図1に示すように、リアホルダ60の後面がハウジング10の後面とほぼ面一に揃えられるとともに、リアホルダ60がハウジング10側に係止され、かつゴム栓40が装着孔17の前面とリアホルダ60の前面との間に挟持される。この場合、ゴム栓40が前後に対称な形状とされ、ゴム栓40の前後方向の構造識別性が喪失されているから、作業者はゴム栓40の挿入の向きを気にする必要がない。
Next, the operation of this embodiment will be described.
The rubber plug 40 and the rear holder 60 are sequentially inserted into the mounting hole 17 of the housing 10 from the rear. Then, as shown in FIG. 1, the rear surface of the rear holder 60 is substantially flush with the rear surface of the housing 10, the rear holder 60 is locked to the housing 10 side, and the rubber plug 40 is connected to the front surface of the mounting hole 17 and the rear holder. It is clamped between the front surface of 60. In this case, since the rubber plug 40 has a symmetrical shape in the front-rear direction and the structure distinguishability in the front-rear direction of the rubber plug 40 is lost, the operator does not have to worry about the insertion direction of the rubber plug 40.

続いて、ハウジング10のキャビティ15内に後方から端子金具80を挿入する。端子金具80は遊挿孔61及び貫通孔41を順次経てキャビティ15内に挿入される。端子金具80が貫通孔41を通過する際、接続部81が案内面44及び最後方の内周リップ43Aの内周面に摺接するが、このとき、端子金具80の最大寸法部分が高さ方向に向けられ、内周リップ43Aの開口形状が高さ方向に長手となる長円形状とされるから、接続部81と貫通孔41の内周面との間に発生する挿入抵抗が格別大きくなることはない。端子金具80の通過後、貫通孔41には電線30が挿入され、挿入された電線30の外周面が各内周リップ43に密着される。この場合、中央に位置する内周リップ43Bによって、電線30の外周面には全周に亘ってほぼ均等な圧縮力が付与されることとなる。   Subsequently, the terminal fitting 80 is inserted into the cavity 15 of the housing 10 from the rear. The terminal fitting 80 is inserted into the cavity 15 through the loose insertion hole 61 and the through hole 41 in order. When the terminal fitting 80 passes through the through hole 41, the connecting portion 81 is in sliding contact with the guide surface 44 and the inner peripheral surface of the rearmost inner lip 43A. At this time, the maximum dimension portion of the terminal fitting 80 is in the height direction. Since the opening shape of the inner peripheral lip 43 </ b> A is an oval shape that is elongated in the height direction, the insertion resistance generated between the connection portion 81 and the inner peripheral surface of the through hole 41 is remarkably increased. There is nothing. After passing through the terminal fitting 80, the electric wire 30 is inserted into the through hole 41, and the outer peripheral surface of the inserted electric wire 30 is in close contact with each inner peripheral lip 43. In this case, a substantially uniform compressive force is applied to the outer peripheral surface of the electric wire 30 over the entire circumference by the inner peripheral lip 43B located at the center.

以上説明したように、本実施形態によれば、ゴム栓40の貫通孔41に端子金具80を挿通させる場合に、内周リップ43Aの開口形状の長手部分に端子金具80の断面外形における最大寸法部分が対応して通過するから、端子金具80とゴム栓40との間に発生する摩擦抵抗が大きくなるのが回避され、電線30の腰折れが防止される。また、スタビライザ87等の突起物と内周リップ43Aとの間の摺動磨耗が低減されるため、ゴム栓40切れも防止される。   As described above, according to the present embodiment, when the terminal fitting 80 is inserted through the through hole 41 of the rubber plug 40, the maximum dimension in the cross-sectional outer shape of the terminal fitting 80 in the longitudinal portion of the opening shape of the inner peripheral lip 43A. Since the portions pass correspondingly, an increase in frictional resistance generated between the terminal fitting 80 and the rubber plug 40 is avoided, and the electric wire 30 is prevented from being folded. Further, since sliding wear between the protrusions such as the stabilizer 87 and the inner peripheral lip 43A is reduced, the rubber plug 40 can be prevented from being cut.

また、ゴム栓40の貫通孔41に端子金具80を挿通させる場合に、開口形状が円形状とされる中央の内周リップ43Bによって、電線30とゴム栓40との間の良好なシール性が確保される。   Further, when the terminal fitting 80 is inserted through the through hole 41 of the rubber plug 40, the central inner lip 43B having a circular opening shape provides a good sealing property between the electric wire 30 and the rubber plug 40. Secured.

さらに、前後両方の内周リップ43Aの開口形状が長円形状とされているから、端子金具80とゴム栓40との間に生じる摩擦抵抗によってゴム栓40が切れるのを、端子金具80を貫通孔41に挿入するときのみならず、端子金具80を貫通孔41から抜き出すときにも防止できる。   Further, since the opening shape of both the front and rear inner peripheral lips 43A is an oval shape, the rubber plug 40 is cut off by the frictional resistance generated between the terminal metal fitting 80 and the rubber plug 40. This can be prevented not only when the terminal fitting 80 is inserted into the hole 41 but also when the terminal fitting 80 is extracted from the through hole 41.

さらにまた、ゴム栓40全体が前後方向(端子金具80の貫通孔41への挿抜方向)に対称形状をなしているから、ゴム栓40の前後の向きを識別する必要がない。このため、例えば、ハウジング10にゴム栓40を装着させるに際し、ゴム栓40を前後いずれの向きからでも装着させることができる。   Furthermore, since the rubber plug 40 as a whole has a symmetrical shape in the front-rear direction (insertion / removal direction with respect to the through hole 41 of the terminal fitting 80), it is not necessary to identify the front-rear direction of the rubber plug 40. For this reason, for example, when the rubber plug 40 is mounted on the housing 10, the rubber plug 40 can be mounted from either front or back.

<実施形態2>
本発明の実施形態2を図5によって説明する。実施形態2では、ゴム栓40Aの内周リップ43C、43Dの形態が実施形態1とは異なっている。その他は実施形態1と同様であるため、ハウジング10等は省略する。
<Embodiment 2>
A second embodiment of the present invention will be described with reference to FIG. In the second embodiment, the inner peripheral lips 43C and 43D of the rubber plug 40A are different from the first embodiment. The other parts are the same as in the first embodiment, and the housing 10 and the like are omitted.

ゴム栓40Aの貫通孔41Aの内周面には、前後3条の内周リップ43C、43Dが突出して形成されている。各内周リップ43C、43Dのうち、最後方及び中央に位置する2条の内周リップ43Cは、最前方に位置する1条の内周リップ43Dとは異形状とされている。具体的には、最前方の内周リップ43Dの開口形状は、ここに挿入される電線30の外周面に沿った真円形状とされている一方、最後方及び中央の2条の内周リップ43Cの開口形状は、ここに挿通される端子金具80の接続部81の最大寸法部分と対応する高さ方向(長さ方向)に長い長円形状(長孔状)とされている。より具体的には、最後方及び中央の2条の内周リップ43Cの内周面における幅寸法は最前方の内周リップ43Dの内周面における幅寸法よりも小さく、最後方及び中央の2条の内周リップ43Cの内周面における高さ寸法は最前方の内周リップ43Dの内周面における高さ寸法よりも大きくされている。   On the inner peripheral surface of the through hole 41A of the rubber plug 40A, three front and rear inner peripheral lips 43C and 43D are formed to protrude. Of the inner peripheral lips 43C and 43D, the two inner peripheral lips 43C positioned at the rearmost and center are different from the one inner peripheral lip 43D positioned at the forefront. Specifically, the opening shape of the foremost inner peripheral lip 43D is a perfect circle shape along the outer peripheral surface of the electric wire 30 inserted therein, while the rearmost and inner two inner peripheral lips The opening shape of 43C is an oval shape (long hole shape) that is long in the height direction (length direction) corresponding to the maximum dimension portion of the connection portion 81 of the terminal fitting 80 inserted therethrough. More specifically, the width dimension of the inner peripheral lip 43C of the innermost lip 43C at the rearmost and central two is smaller than the width dimension of the inner peripheral lip 43D of the foremost inner peripheral lip 43D. The height dimension of the inner peripheral lip 43C of the strip is made larger than the height dimension of the inner peripheral lip 43D of the foremost inner peripheral lip 43D.

また、ゴム栓40Aの後面に開口する貫通孔41Aの後端部には、端子金具80の挿入時に、端子金具80の貫通孔41Aへの挿入案内をなす後方案内面46がテーパ状に拡開して形成されている。後方案内面46は、最後方の内周リップ43Cの内周面から連続して高さ方向に長い円環状をなしている。一方、ゴム栓40の前面に開口する貫通孔41Aの前端部には、端子金具80の抜取時に、端子金具80の貫通孔41Aへの挿入案内をなす前方案内面47がテーパ状に拡開して形成されている。この前方案内面47は、最前方の内周リップ43Dの内周面から連続する真円環状をなしている。   Further, at the rear end portion of the through hole 41A that opens on the rear surface of the rubber plug 40A, a rear guide surface 46 that guides insertion of the terminal fitting 80 into the through hole 41A when the terminal fitting 80 is inserted widens in a tapered shape. Is formed. The rear guide surface 46 has an annular shape that is continuous in the height direction from the inner peripheral surface of the rearmost inner peripheral lip 43C. On the other hand, at the front end portion of the through hole 41A that opens to the front surface of the rubber plug 40, when the terminal fitting 80 is removed, a front guide surface 47 that guides insertion of the terminal fitting 80 into the through hole 41A is expanded in a tapered shape. Is formed. The front guide surface 47 has a perfect circular shape that is continuous from the inner peripheral surface of the foremost inner peripheral lip 43D.

実施形態2によれば、端子金具80の接続部81に近い貫通孔41Aへの挿通方向出口側に位置する、最前方の内周リップ43Dの開口形状が、電線30の外周面に沿った真円形状とされているから、端子金具80の接続部81に近い位置で良好なシール性が確保され、接続信頼性が向上する。   According to the second embodiment, the opening shape of the foremost inner peripheral lip 43 </ b> D located on the outlet side in the insertion direction to the through hole 41 </ b> A close to the connection portion 81 of the terminal fitting 80 is true along the outer peripheral surface of the electric wire 30. Since it is circular, good sealing performance is secured at a position close to the connection portion 81 of the terminal fitting 80, and connection reliability is improved.

<実施形態3>
図6及び図7は、本発明の実施形態3を示す。実施形態3では、ゴム栓40Bの外周リップ42、42Aの形態及びハウジング10Aの装着孔17Aの形態が実施形態1とは異なっている。その他は実施形態1と同様である。
<Embodiment 3>
6 and 7 show Embodiment 3 of the present invention. In the third embodiment, the shape of the outer peripheral lips 42 and 42A of the rubber plug 40B and the shape of the mounting hole 17A of the housing 10A are different from those of the first embodiment. Others are the same as in the first embodiment.

ゴム栓40Bの外周面には、前後3条の外周リップ42が突出して形成されている。各外周リップ42、42Aのうち最後方(ゴム栓40の貫通孔41への挿入方向最後尾)に位置する1条の外周リップ42Aは、他の2条の外周リップ42よりも突出寸法が大きく、他よりも高背とされている。   On the outer peripheral surface of the rubber plug 40B, three front and rear outer peripheral lips 42 are formed so as to protrude. One outer peripheral lip 42A located at the rear end of each outer peripheral lip 42, 42A (the rearmost end in the insertion direction of the rubber plug 40 into the through hole 41) has a larger projecting dimension than the other two outer peripheral lips 42. , Being taller than others.

一方、ハウジング10における装着孔17Aの内周面には、前後方向途中に段差29が形成され、段差29を境とした後方の領域(入り口側)の開口径が前方の領域(奥側)の開口径よりも大きくされている。なお、内周リップ43C、43Dの形態は実施形態2と同様であって、最後方及び中央に位置する2条の内周リップ43Cの開口形状が高さ方向に長い長円形状とされ、最前方に位置する1状の内周リップ43Dの開口形状が電線30の外周面に沿った真円形状とされている。   On the other hand, a step 29 is formed on the inner peripheral surface of the mounting hole 17A in the housing 10 in the front-rear direction, and the opening diameter of the rear region (entrance side) with the step 29 as a boundary is the front region (back side). It is larger than the opening diameter. The forms of the inner peripheral lips 43C and 43D are the same as those in the second embodiment, and the opening shape of the two inner peripheral lips 43C located at the rearmost and the center is an elliptical shape that is long in the height direction. The opening shape of the one inner peripheral lip 43 </ b> D located in front is a perfect circle shape along the outer peripheral surface of the electric wire 30.

実施形態3によれば、ゴム栓40Bの外周リップ42、42Aのうち装着孔17Aへの挿入方向最後尾に位置する外周リップ42Aが他よりも高背とされ、ハウジング10における装着孔17Aの開口径が外周リップ42、42Aと対応して入り口側が奥側よりも大きくされているから、ゴム栓40Bが前後に反転した状態で装着孔17Aに挿入されるのを確実に回避できる。しかも、実施形態3によれば、最前方の内周リップ43Dの開口形状が電線30の外周面に沿った円形状とされているから、端子金具80の接続部81に近い位置で良好なシール性が確保されるという、実施形態2の利益を享受できる。   According to the third embodiment, the outer peripheral lip 42A of the outer peripheral lips 42, 42A of the rubber plug 40B located at the rearmost end in the insertion direction into the mounting hole 17A is made taller than others, and the mounting hole 17A in the housing 10 is opened. Since the inlet side is made larger than the back side in correspondence with the outer peripheral lips 42 and 42A, it is possible to reliably avoid the rubber plug 40B being inserted into the mounting hole 17A in a state where the rubber plug 40B is reversed forward and backward. Moreover, according to the third embodiment, since the opening shape of the foremost inner peripheral lip 43D is a circular shape along the outer peripheral surface of the electric wire 30, a good seal is obtained at a position close to the connection portion 81 of the terminal fitting 80. The benefit of the second embodiment that the performance is ensured can be enjoyed.
