この種の防水コネクタとしては、例えば下記特許文献1に記載の防水コネクタが知られている。この防水コネクタは互いに嵌合可能な雌雄両コネクタを備え、雄コネクタには、特許文献1の図1に示すように、断面略楕円形の筒状をなすフード部が設けられている。フード部には、雌コネクタに設けられた雌コネクタハウジングが嵌合可能とされており、嵌合状態となったフード部と雌コネクタハウジングとの間には防水用のゴムリングが挟まれている。また、雌コネクタハウジングの周面にリブを突出して設けておき、このリブをフード部の周面に当接させることで嵌合状態となった雌雄両コネクタ間のがたつきを規制する構成が一般に知られている。
特開2003−151682公報(図1)
As this type of waterproof connector, for example, a waterproof connector described in Patent Document 1 below is known. This waterproof connector includes both male and female connectors that can be fitted to each other. As shown in FIG. 1 of Patent Document 1, the male connector is provided with a hood having a substantially elliptical cross section. A female connector housing provided on the female connector can be fitted to the hood portion, and a waterproof rubber ring is sandwiched between the hood portion and the female connector housing in the fitted state. . Also, a rib is provided on the peripheral surface of the female connector housing, and the rib is brought into contact with the peripheral surface of the hood portion to regulate rattling between the male and female connectors that are in a fitted state. Generally known.
Japanese Patent Laid-Open No. 2003-151682 (FIG. 1)

例えば、上記した防水コネクタでは雌コネクタハウジングとフード部との間にゴムリングを挟む隙間があるため、雌コネクタハウジングとフード部とが正規の嵌合方向に対して傾いた状態で嵌合される、いわゆるこじり嵌合がなされる場合があり得る。このようなこじり嵌合や車体からの振動等によってリブがフード部に対して位置ずれしてしまうと、リブがフード部の周面から離れてしまい、がたつきを規制することができなくなる。要するに、フード部が断面略円形や断面略楕円形の筒状に形成されている場合には、フード部の周面においてリブと当接可能な部分が一点しか存在しないため、こじり嵌合等によってリブが位置ずれしてしまうと、もはやリブをフード部の周面に当接させることができなくなる。   For example, in the above-described waterproof connector, there is a gap for sandwiching the rubber ring between the female connector housing and the hood portion, so that the female connector housing and the hood portion are fitted in a tilted state with respect to the normal fitting direction. There may be a case where a so-called twist fitting is performed. If the rib is displaced with respect to the hood portion due to such a tight fitting or vibration from the vehicle body, the rib is separated from the peripheral surface of the hood portion, and rattling cannot be regulated. In short, when the hood part is formed in a cylindrical shape with a substantially circular cross section or a substantially elliptical cross section, there is only one point that can contact the rib on the peripheral surface of the hood part. If the rib is displaced, the rib can no longer be brought into contact with the peripheral surface of the hood portion.

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、防水コネクタにおいてリブがフード部に対して位置ずれしても雌雄両コネクタ間のがたつきを規制可能にすることを目的とする。   The present invention has been completed based on the above circumstances, and it is an object of the present invention to make it possible to regulate rattling between both male and female connectors even if the ribs of the waterproof connector are displaced from the hood portion. And

本発明は、雄コネクタと、前記雄コネクタに突出して設けられ、断面略円形又は断面略楕円形の筒状をなすフード部と、前記雄コネクタと嵌合可能な雌コネクタと、前記雌コネクタに設けられ、前記雌雄両コネクタが嵌合状態となるに伴って前記フード部と嵌合する雌コネクタハウジングと、前記嵌合状態となった前記フード部と前記雌コネクタハウジングとの間に挟まれるゴムリングとを備えた防水コネクタであって、前記雌コネクタハウジングの周面に設けられ、第1の方向に突出する第1リブと、前記雌コネクタハウジングの周面に設けられ、前記第1の方向とは反対方向となる第2の方向に突出する第2リブと、前記フード部の周面を平面状に肉盛りして設けられ、前記第1リブの突出端を受ける平面と前記第2リブの突出端を受ける平面とが平行に配置されることで嵌合状態となった前記雌雄両コネクタ間のがたつきを規制する受け部とを備えており、前記雌コネクタハウジングは、前記フード部の内部に嵌合可能な本体部を備え、前記第1及び第2リブは、前記本体部の外周面にそれぞれ配置され、前記受け部は、前記フード部の内周面に配置されているとともに、前記雌コネクタハウジングは、前記フード部を内部に受け入れて嵌合可能な嵌合筒部を備え、かつ前記フード部は、その外周面に設けられ前記雌雄両コネクタの嵌合方向に延びるガイド片を備え、前記嵌合筒部は、その内周面に設けられ前記ガイド片を受け入れて前記雌雄両コネクタの嵌合を案内するガイド凹部を備え、前記第1及び第2リブは、前記ガイド凹部の内壁にそれぞれ配置され、前記受け部は、前記ガイド片の外面に配置されている構成としたところに特徴を有する。 The present invention provides a male connector, a hood portion that protrudes from the male connector and has a substantially circular or substantially elliptical cross section, a female connector that can be fitted to the male connector, and the female connector. A female connector housing that is fitted to the hood as the male and female connectors are in a fitted state, and rubber that is sandwiched between the hood and the female connector housing in the fitted state A waterproof connector including a ring, provided on a peripheral surface of the female connector housing, and protruding in a first direction; provided on the peripheral surface of the female connector housing; and the first direction. A second rib projecting in a second direction opposite to the first direction, a flat surface receiving the projecting end of the first rib, and a second rib provided on the peripheral surface of the hood portion. Receiving the protruding end of Plane and is provided with a receiving portion for regulating the backlash between the male and female connectors became fitted state by being arranged parallel to, the female connector housing, fitted to the inside of the hood portion A main body portion, and the first and second ribs are respectively disposed on an outer peripheral surface of the main body portion, and the receiving portion is disposed on an inner peripheral surface of the hood portion, and the female connector housing Is provided with a fitting tube portion that can be fitted and received inside the hood portion, and the hood portion is provided with a guide piece provided on an outer peripheral surface thereof and extending in a fitting direction of the male and female connectors. The tube section includes a guide recess provided on an inner peripheral surface thereof for receiving the guide piece and guiding the fitting of the male and female connectors, and the first and second ribs are respectively disposed on the inner walls of the guide recess. The receiving part , Characterized in was a configuration that is disposed on the outer surface of the guide piece.

このような構成によると、雌雄両コネクタの嵌合に伴ってフード部と雌コネクタハウジングとが嵌合する。雌雄両コネクタが嵌合状態に至ると、第1の方向に突出する第1リブの突出端が受け部の平面に接触すると共に、第1の方向とは反対方向となる第2の方向に突出する第2リブの突出端が受け部の平面に接触することで、雌雄両コネクタが第1の方向及び第2の方向にがたつくことが規制される。さらに、第1リブの突出端を受ける平面と第2リブの突出端を受ける平面とが平行となるように配置したから、例えば雌雄両コネクタがこじられる等して第1及び第2リブがこれらを受ける平面の面方向に位置ずれしても、第1及び第2リブが平面に接触した状態に保たれ、雌雄両コネクタ間のがたつきが規制される。   According to such a configuration, the hood portion and the female connector housing are fitted together with the fitting of the male and female connectors. When both the male and female connectors are in the fitted state, the protruding end of the first rib protruding in the first direction contacts the plane of the receiving portion and protrudes in the second direction opposite to the first direction. The protruding end of the second rib that comes into contact with the plane of the receiving portion restricts the male and female connectors from rattling in the first direction and the second direction. Furthermore, since the plane that receives the protruding end of the first rib and the plane that receives the protruding end of the second rib are arranged in parallel, for example, the first and second ribs are moved by twisting both male and female connectors. The first and second ribs are kept in contact with the flat surface even if they are displaced in the plane direction of the receiving plane, and rattling between the male and female connectors is restricted.

また雌コネクタハウジングは、フード部の内部に嵌合可能な本体部を備え、第1及び第2リブは、本体部の外周面にそれぞれ配置され、受け部は、フード部の内周面に配置されている構成であるから、フード部と本体部との間におけるがたつきを規制することができる。
さらに雌コネクタハウジングは、フード部を内部に受け入れて嵌合可能な嵌合筒部を備え、フード部は、その外周面に設けられ雌雄両コネクタの嵌合方向に延びるガイド片を備え、嵌合筒部は、その内周面に設けられガイド片を受け入れて雌雄両コネクタの嵌合を案内するガイド凹部を備え、第1及び第2リブは、ガイド凹部の内壁にそれぞれ配置され、受け部は、ガイド片の外面に配置されている構成となっている。そのため、ガイド凹部がガイド片を受け入れることで雌雄両コネクタの嵌合を案内することができる。特にこのガイド片及びガイド凹部を利用して各リブ及び受け部を設けたから、ガイド機能部(ガイド凹部及びガイド片)とがたつき規制部(各リブ及び受け部)とを別々に設ける場合よりも全体の構成を簡素化することができる。
The female connector housing includes a body portion that can be fitted inside the hood portion, the first and second ribs are disposed on the outer peripheral surface of the main body portion, and the receiving portion is disposed on the inner peripheral surface of the hood portion. Since it is the structure currently performed, the rattling between a food | hood part and a main-body part can be controlled.
Furthermore, the female connector housing includes a fitting tube portion that can be received and fitted into the hood portion, and the hood portion includes a guide piece that is provided on the outer peripheral surface thereof and extends in the fitting direction of the male and female connectors. The cylindrical portion includes a guide recess provided on the inner peripheral surface thereof for receiving the guide piece and guiding the fitting of the male and female connectors. The first and second ribs are respectively disposed on the inner walls of the guide recess, and the receiving portion is The structure is arranged on the outer surface of the guide piece. Therefore, the fitting of the male and female connectors can be guided by the guide recess receiving the guide piece. In particular, since the ribs and the receiving portions are provided using the guide pieces and the guide concave portions, the guide function portions (the guide concave portions and the guide pieces) and the rattling regulating portions (the ribs and the receiving portions) are separately provided. In addition, the overall configuration can be simplified.

本発明の実施の態様として、以下の構成が好ましい。
本体部は、フード部との嵌合面側に冠着されその冠着状態でフード部の内部に嵌合可能な有底筒状のキャップを備え、第1及び第2リブは、キャップの外周面に設けられている構成としてもよい。このような構成によると、フード部との嵌合面側にキャップが冠着された状態で本体部をフード部の内部に嵌合したときにおいても、フード部と本体部との間におけるがたつきを規制することができる。
The following configuration is preferable as an embodiment of the present invention.
The main body portion is provided with a bottomed cylindrical cap that is crowned on the fitting surface side with the hood portion and can be fitted into the hood portion in the crowned state, and the first and second ribs are the outer periphery of the cap. It is good also as a structure provided in the surface. According to such a configuration, even when the main body portion is fitted inside the hood portion with the cap attached to the fitting surface side with the hood portion, rattling between the hood portion and the main body portion is achieved. You can regulate the date.

受け部は、フード部の内部における奥方に配置され、雌雄両コネクタの嵌合完了時に第1及び第2リブの突出端を受けることで雌雄両コネクタ間のがたつきを規制する構成としてもよい。雌雄両コネクタ間のがたつき規制が行われると、第1及び第2リブが受け部に接触して摩擦抵抗が大きくなることで、雌雄両コネクタの嵌合操作力が大きくなる。その点、上記構成によると、雌雄両コネクタの嵌合完了時に、がたつき規制が行われる。すなわち、雌雄両コネクタの嵌合途上においてはがたつき規制が行われないため、嵌合操作力が小さくて済む。   The receiving portion may be disposed in the back of the hood portion, and may be configured to restrict rattling between the male and female connectors by receiving the protruding ends of the first and second ribs when the male and female connectors are completely fitted. . When rattling between the male and female connectors is restricted, the first and second ribs come into contact with the receiving portions and the frictional resistance increases, so that the fitting operation force of the male and female connectors increases. In that respect, according to the above configuration, rattling is restricted when the male and female connectors are completely fitted. That is, since the rattling is not regulated during the mating of the male and female connectors, the fitting operation force can be small.

受け部は、フード部の周面のうち嵌合状態において第1及び第2リブと対応する位置にのみ設けられている構成としてもよい。このような構成によると、第1及び第2リブと対応する位置にのみ受け部を設けたから、フード部全体が厚肉になることがない。   A receiving part is good also as a structure provided only in the position corresponding to a 1st and 2nd rib in a fitting state among the surrounding surfaces of a food | hood part. According to such a configuration, since the receiving portion is provided only at a position corresponding to the first and second ribs, the entire hood portion does not become thick.

本発明によれば、防水コネクタにおいてリブがフード部に対して位置ずれしても雌雄両コネクタ間のがたつきを規制することができる。   According to the present invention, rattling between the male and female connectors can be restricted even if the rib is displaced from the hood portion in the waterproof connector.

アーム部52の内面には、カム溝53が凹設されている。また、嵌合筒部33の幅方向両側には、嵌合筒部33の内部と外部を連通する切り欠き44が設けられている。この切り欠き44は、待機位置にある操作レバー50のカム溝53の入口と整合する位置に配されている。また、切り欠き44は、嵌合筒部33の前縁から後方に向けて切り欠かれており、フード部12が本体部32と嵌合筒部33との間に進入するに伴ってカムピン13を後方へ移動可能としてある。また、アーム部52の内面においてカム溝53の入口付近には、操作レバー50を待機位置にて保持するための回り止め突部54が設けられている。回り止め突部54は、操作レバー50が待機位置にあるときに切り欠き44内部に入り込み、切り欠き44の内壁における上面に係止する。   A cam groove 53 is recessed in the inner surface of the arm portion 52. Further, on both sides in the width direction of the fitting tube portion 33, notches 44 that communicate the inside and the outside of the fitting tube portion 33 are provided. The notch 44 is arranged at a position aligned with the entrance of the cam groove 53 of the operating lever 50 in the standby position. The notch 44 is notched rearward from the front edge of the fitting cylinder portion 33, and the cam pin 13 is moved as the hood portion 12 enters between the main body portion 32 and the fitting cylinder portion 33. Can be moved backward. Further, an anti-rotation projection 54 for holding the operation lever 50 at the standby position is provided near the entrance of the cam groove 53 on the inner surface of the arm portion 52. The anti-rotation protrusion 54 enters the notch 44 when the operation lever 50 is in the standby position, and is locked to the upper surface of the inner wall of the notch 44.

一方、フード部12の外周面においてカムピン13の上方には、解除突部17が設けられている。解除突部17は、フード部12を本体部32と嵌合筒部33との間に嵌合させることによりカムピン13と共に切り欠き44の内部に進入し、回り止め突部54の内側に入り込んで回り止め突部54を切り欠き44の外部に押し出すように構成されている。回り止め突部54が切り欠き44の外部に押し出されると、アーム部52が幅方向両側に開き変形し、回り止め突部54と切り欠き44の内壁上面との係止状態が解除されることにより、操作レバー50の回動操作が許容される。   On the other hand, a release protrusion 17 is provided above the cam pin 13 on the outer peripheral surface of the hood portion 12. The release protrusion 17 enters the inside of the notch 44 together with the cam pin 13 by fitting the hood part 12 between the main body part 32 and the fitting cylinder part 33, and enters the inside of the rotation prevention protrusion 54. The rotation preventing projection 54 is configured to be pushed out of the notch 44. When the rotation preventing projection 54 is pushed out of the notch 44, the arm portion 52 opens and deforms on both sides in the width direction, and the locking state between the rotation preventing projection 54 and the inner wall upper surface of the notch 44 is released. Thus, the turning operation of the operation lever 50 is allowed.

カムピン13は、カム溝53の入口における内壁下面に設けられた抜止突起58によってカム溝53の入口から外れてしまうことが規制されている。カムピン13をカム溝53の入口に進入させた後、待機位置にある操作レバー50を嵌合位置に向けて回動させると、カムピン13とカム溝53の側壁とが係止し、カム作用によってカムピン13がカム溝53に沿って奥方へと移動する。これにより、雌雄両コネクタ10,30が嵌合し、正規嵌合に至るとフード部12が本体部32と嵌合筒部33との間に嵌合する。これと並行して、雄端子金具20は、キャップ34の端子挿通孔36を通じてキャビティ35内部及び雌端子金具40の端子接続部の内部に進入し、弾性接触片と弾性的に接触する。   The cam pin 13 is restricted from coming off from the inlet of the cam groove 53 by a retaining protrusion 58 provided on the lower surface of the inner wall at the inlet of the cam groove 53. After the cam pin 13 has entered the entrance of the cam groove 53, when the operation lever 50 in the standby position is rotated toward the fitting position, the cam pin 13 and the side wall of the cam groove 53 are locked, and the cam action causes The cam pin 13 moves to the back along the cam groove 53. Thereby, both the male and female connectors 10 and 30 are fitted, and when the normal fitting is reached, the hood portion 12 is fitted between the main body portion 32 and the fitting cylinder portion 33. In parallel with this, the male terminal fitting 20 enters the inside of the cavity 35 and the inside of the terminal connection portion of the female terminal fitting 40 through the terminal insertion hole 36 of the cap 34 and elastically contacts the elastic contact piece.

雌コネクタハウジング31の上部後端には、嵌合位置にある操作レバー50を保持するための保持部45が後方に張り出し形成されている。保持部45の後端には、操作部51に撓み可能に設けられた撓み係止片55と係止する保持突部46が設けられている。撓み係止片55が保持突部46と係止した状態では、嵌合位置にある操作レバー50が待機位置へ回動することが規制される。撓み係止片55の突出端には解除操作部56が設けられている。この解除操作部56を指で摘んで撓み係止片55と保持突部46との係止状態を解除することで、嵌合位置にある操作レバー50を待機位置へ回動することが許容される。   At the upper rear end of the female connector housing 31, a holding portion 45 for holding the operation lever 50 in the fitting position is formed to project rearward. At the rear end of the holding portion 45, a holding projection 46 is provided that engages with a bending locking piece 55 that is provided on the operation portion 51 so as to be bent. In a state where the bending locking piece 55 is locked to the holding projection 46, the operation lever 50 in the fitting position is restricted from rotating to the standby position. A release operation portion 56 is provided at the protruding end of the bending locking piece 55. By holding the release operation portion 56 with a finger and releasing the locking state between the bending locking piece 55 and the holding projection 46, the operation lever 50 in the fitting position is allowed to rotate to the standby position. The

さて、前述したようにフード部12の詳細な構造について説明する。フード部12の外周面は、図5に示すように、前後方向に形成されている。一方、フード部12の内周面は奥壁側から開口縁側に向けて開いた形状をなしている。つまり、フード部12は、奥壁側に位置して小さい内径を有する小径部12Aと、開口縁側に位置して大きい内径を有する大径部12Cと、小径部12Aと大径部12Cとの間に位置するつなぎ部12Bとを備え、各部12A,12B,12Cが同軸で一体に構成されている。   Now, as described above, the detailed structure of the hood portion 12 will be described. The outer peripheral surface of the hood part 12 is formed in the front-rear direction as shown in FIG. On the other hand, the inner peripheral surface of the hood portion 12 has a shape opened from the back wall side toward the opening edge side. That is, the hood portion 12 is located between the small diameter portion 12A having a small inner diameter located on the back wall side, the large diameter portion 12C having a large inner diameter located on the opening edge side, and the small diameter portion 12A and the large diameter portion 12C. And 12A, 12B, and 12C are coaxially and integrally configured.

フード部12の大径部12Cの内周面は、図6に示すように、雌雄両コネクタ10,30の嵌合状態においてゴムリング80の外周面と密着し、これに伴ってゴムリング80の内周面が本体部32の外周面に密着する。一方、フード部12の小径部12Aの内周面は、図7に示すように、キャップ34の外周面とほぼ適合するように形成されている。キャップ34の周壁34Bには、図2に示すように、図示8個の内側リブ47が前後方向に延びて設けられており、これらの内側リブ47がフード部12の小径部12Aの内周面に接触することで、雌雄両コネクタ10,30の嵌合完了時に、フード部12と本体部32との間のがたつきが規制されるようにしてある。   As shown in FIG. 6, the inner peripheral surface of the large-diameter portion 12C of the hood portion 12 is in close contact with the outer peripheral surface of the rubber ring 80 when the male and female connectors 10 and 30 are fitted together. The inner peripheral surface is in close contact with the outer peripheral surface of the main body portion 32. On the other hand, the inner peripheral surface of the small-diameter portion 12A of the hood portion 12 is formed so as to substantially match the outer peripheral surface of the cap 34, as shown in FIG. As shown in FIG. 2, eight inner ribs 47 shown in the figure extend in the front-rear direction on the peripheral wall 34 </ b> B of the cap 34, and these inner ribs 47 are the inner peripheral surface of the small-diameter portion 12 </ b> A of the hood portion 12. When the fitting of the male and female connectors 10 and 30 is completed, rattling between the hood portion 12 and the main body portion 32 is regulated.

キャップ34の周壁34Bは断面略方形をなしており、8個の内側リブ47は周壁34Bにおける上下左右の4辺にそれぞれ2つずつ配置され、一対の上リブ(本発明の「第1リブ」の一例)47Aと一対の下リブ(本発明の「第2リブ」の一例)47Bと一対の左リブ(本発明の「第1リブ」の一例)47Cと一対の右リブ(本発明の「第2リブ」の一例)47Dとから構成されている。両上リブ47Aは、周壁34Bの上辺における両端側において上方に突出して設けられている。両下リブ47Bは、周壁34Bの下辺における両端側において下方に突出して設けられている。両上リブ47Aと両下リブ47Bとはそれぞれ上下に対応する位置に設けられている。尚、上方は本発明の「第1の方向」の一例であり、下方は本発明の「第2の方向」の一例である。   The peripheral wall 34B of the cap 34 has a substantially square cross section, and the eight inner ribs 47 are arranged on each of the four sides on the top, bottom, left, and right of the peripheral wall 34B, and a pair of upper ribs (the “first rib” of the present invention). An example) 47A, a pair of lower ribs (an example of the “second rib” of the present invention) 47B, a pair of left ribs (an example of the “first rib” of the present invention) 47C, and a pair of right ribs (the “ An example of “second rib” 47D. Both upper ribs 47A are provided so as to protrude upward at both end sides on the upper side of the peripheral wall 34B. Both lower ribs 47B are provided so as to protrude downward on both end sides of the lower side of the peripheral wall 34B. The upper ribs 47A and the lower ribs 47B are provided at positions corresponding to the upper and lower sides, respectively. The upper part is an example of the “first direction” in the present invention, and the lower part is an example of the “second direction” in the present invention.

両左リブ47Cは、周壁34Bの左辺において上下方向に所定の間隔を空けて配置され、それぞれ左方に突出して設けられている。両右リブ47Dは、周壁34Bの右辺において上下方向に所定の間隔を空けて配置され、それぞれ右方に突出して設けられている。両左リブ47Cと両右リブ47Dとはそれぞれ左右に対応する位置に設けられている。   Both left ribs 47C are arranged at predetermined intervals in the vertical direction on the left side of the peripheral wall 34B, and are provided to protrude to the left. Both right ribs 47D are arranged at predetermined intervals in the vertical direction on the right side of the peripheral wall 34B, and are provided so as to protrude rightward. Both left ribs 47C and right ribs 47D are provided at positions corresponding to the left and right.

一方、フード部12の小径部12Aにおける内周面には、リブ47の突出端を受ける受け部18が設けられている。受け部18は、小径部12Aにおける上下左右の4辺に配置され、小径部12Aの内周面を肉盛りすることにより平面状に形成されたストレート面(本発明の「第1及び第2リブの突出端を受ける平面」の一例)18Aを備えている。小径部12Aの内周面には、図示6個の受け部18が形成されている。上リブ47Aの突出端と接触するストレート面18Aは、下リブ47Bの突出端と接触するストレート面18Aに対して平行に設定されている。また、左リブ47Cの突出端と接触するストレート面18Aは、右リブ47Dの突出端と接触するストレート面18Aに対して平行に設定されている。   On the other hand, a receiving portion 18 that receives the protruding end of the rib 47 is provided on the inner peripheral surface of the small diameter portion 12 </ b> A of the hood portion 12. The receiving portions 18 are arranged on four sides of the small-diameter portion 12A on the top, bottom, left, and right sides, and are straight surfaces (“first and second ribs” of the present invention) formed in a flat shape by building up the inner peripheral surface of the small-diameter portion 12A. An example) 18A. The six receiving portions 18 shown in the figure are formed on the inner peripheral surface of the small diameter portion 12A. The straight surface 18A that contacts the protruding end of the upper rib 47A is set in parallel to the straight surface 18A that contacts the protruding end of the lower rib 47B. The straight surface 18A that contacts the protruding end of the left rib 47C is set in parallel to the straight surface 18A that contacts the protruding end of the right rib 47D.

両上リブ47Aと両下リブ47Bに対しては、それぞれ個別に受け部18が設けられているものの、両左リブ47Cと両右リブ47Dに対しては、それぞれ共通の受け部18が設けられている。この理由は、両左リブ47Cと両右リブ47Dは、周壁34Bの短辺側において比較的近い位置に設けられており、共通の受け部18を設けてもフード部12がさほど厚肉にならないからである。ところが、両上リブ47Aと両下リブ47Bは、周壁34Bの長辺側における両端付近に設けられており、周壁34Bの長辺側に共通の受け部18を設け、左右に長いストレート面18Aを形成してしまうと、その分だけフード部12が厚肉になってしまうからである。尚、受け部18が設けられている位置を明確にするため、図1においては、2本の破線で挟まれた領域として表示してある。   The receiving portions 18 are individually provided for the upper ribs 47A and the lower ribs 47B, respectively, but the common receiving portions 18 are provided for the left ribs 47C and the right ribs 47D. ing. This is because both the left ribs 47C and the right ribs 47D are provided at relatively close positions on the short side of the peripheral wall 34B, and the hood portion 12 does not become so thick even if the common receiving portion 18 is provided. Because. However, the upper ribs 47A and the lower ribs 47B are provided near both ends on the long side of the peripheral wall 34B, the common receiving portion 18 is provided on the long side of the peripheral wall 34B, and the long straight surfaces 18A are formed on the left and right. This is because, if formed, the hood portion 12 becomes thicker by that amount. In addition, in order to clarify the position where the receiving part 18 is provided, in FIG. 1, it displays as an area | region pinched | interposed by two broken lines.

両第1ガイド凹部42の内壁下面及び両第2ガイド凹部43の内壁上面には、それぞれ外側リブ48が前後方向に延びて設けられており、図示4個の外側リブ48がフード部12の大径部12Cの外周面に接触することで、嵌合状態におけるフード部12と嵌合筒部33間のがたつきが規制される。外側リブ48は、図2に示すように、第2ガイド凹部43に配置された図示2個の上リブ(本発明の「第1リブ」の一例)48Aと、第1ガイド凹部42に配置された図示2個の下リブ(本発明の「第2リブ」の一例)48Bとから構成されている。また、外側リブ48は、図5に示すように、リテーナ収容部41よりも奥方に設けられているため、雌雄両コネクタ10,30の嵌合完了時にがたつきを規制可能である。   Outer ribs 48 are provided to extend in the front-rear direction on the inner wall lower surface of both first guide recesses 42 and the inner wall upper surface of both second guide recesses 43, respectively. By contacting the outer peripheral surface of the diameter portion 12C, rattling between the hood portion 12 and the fitting cylinder portion 33 in the fitted state is restricted. As shown in FIG. 2, the outer rib 48 is disposed in the two upper ribs 48 </ b> A (an example of the “first rib” in the present invention) 48 </ b> A disposed in the second guide recess 43 and the first guide recess 42. 2B (an example of the “second rib” in the present invention) 48B shown in the drawing. Further, as shown in FIG. 5, the outer rib 48 is provided behind the retainer accommodating portion 41, so that rattling can be restricted when the male and female connectors 10 and 30 are completely fitted.

外側リブ48の上リブ48Aに対しては、第2ガイド片15の上面が受け部18のストレート面18Aとして機能する。また、外側リブ48の下リブ48Bに対しては、第1ガイド片14の下面が受け部18のストレート面18Aとして機能する。第2ガイド片15の上面は平面状をなし、同じく平面状に形成された第1ガイド片14の下面に対して平行となるように設定されている。このように、既存構造である各ガイド片14,15及び各ガイド凹部42,43を利用して上下リブ48A,48B及び受け部18を設けたから、大きな設計変更を伴うことなく嵌合状態にあるフード部12と嵌合筒部33間のがたつきを規制することができる。   For the upper rib 48A of the outer rib 48, the upper surface of the second guide piece 15 functions as the straight surface 18A of the receiving portion 18. For the lower rib 48B of the outer rib 48, the lower surface of the first guide piece 14 functions as the straight surface 18A of the receiving portion 18. The upper surface of the second guide piece 15 has a planar shape, and is set to be parallel to the lower surface of the first guide piece 14 that is also formed in a planar shape. As described above, since the upper and lower ribs 48A and 48B and the receiving portion 18 are provided by using the guide pieces 14 and 15 and the guide recesses 42 and 43, which are existing structures, they are in a fitted state without any major design change. The rattling between the hood part 12 and the fitting cylinder part 33 can be regulated.

本実施形態は以上の構成であって、続いてその作用を説明する。
まず、操作レバー50を図3に示す待機位置にセットしておき、雌雄両コネクタ10,30を嵌合させる。すると、フード部12は本体部32と嵌合筒部33との間に進入し、カムピン13は切り欠き44を通じてカム溝53の入口に進入する。このとき、解除突部17が回り止め突部54の内側に入り込み、回り止め突部54を切り欠き44の外部に押し出すことにより、回り止め突部54と切り欠き44の内壁上面との係止状態が解除される。
The present embodiment has the above configuration, and the operation thereof will be described subsequently.
First, the operating lever 50 is set at the standby position shown in FIG. 3, and the male and female connectors 10 and 30 are fitted. Then, the hood part 12 enters between the main body part 32 and the fitting cylinder part 33, and the cam pin 13 enters the inlet of the cam groove 53 through the notch 44. At this time, the release protrusion 17 enters the inside of the anti-rotation protrusion 54 and pushes the anti-rotation protrusion 54 to the outside of the notch 44, thereby locking the anti-rotation protrusion 54 and the upper surface of the inner wall of the notch 44. The state is released.

次に、操作レバー50を待機位置から嵌合位置へと回動させる。カムピン13はカム作用によってカム溝53の奥方へ移動し、カムピン13が切り欠き44の後方へ相対的に移動すると、雌雄両コネクタ10,30の嵌合が進行する。このとき、各ガイド片14,15,16が各ガイド凹部37,42,43に受け入れられることで雌雄両コネクタ10,30の嵌合動作が案内される。これと共に、フード部12は本体部32と嵌合筒部33との間に進入し、ゴムリング80がフード部12の内周面と本体部32の外周面との間で圧縮状態で挟まれる。   Next, the operation lever 50 is rotated from the standby position to the fitting position. The cam pin 13 moves to the back of the cam groove 53 by the cam action, and when the cam pin 13 relatively moves to the rear of the notch 44, the male and female connectors 10 and 30 are engaged. At this time, the guide pieces 14, 15, 16 are received in the respective guide recesses 37, 42, 43, whereby the fitting operation of the male and female connectors 10, 30 is guided. At the same time, the hood portion 12 enters between the main body portion 32 and the fitting cylinder portion 33, and the rubber ring 80 is sandwiched between the inner peripheral surface of the hood portion 12 and the outer peripheral surface of the main body portion 32 in a compressed state. .

こうして、操作レバー50が図4に示す嵌合位置に回動されると、雌雄両コネクタ10,30が嵌合状態に至り、図8に示すように、内側リブ47と外側リブ48がそれぞれ受け部18のストレート面18Aに接触した状態に保持される。この状態では、フード部12とキャップ34(本体部32)との間で上下左右にがたつくことが規制されると共に、フード部12と嵌合筒部33との間で上下にがたつくことが規制され、雌雄両コネクタ10,30間のがたつきが規制される。尚、操作レバー50が嵌合位置に至ると、操作部51の撓み係止片55が保持部45の保持突部46に係止することで、操作レバー50が嵌合位置に保持される。さらに、雄端子金具20は雌端子金具40の弾性接触片と弾性的に接触し、雌雄両端子金具20,40に連なる電線W同士が導通可能に接続される。   Thus, when the operating lever 50 is rotated to the mating position shown in FIG. 4, the male and female connectors 10 and 30 are brought into the mating state, and the inner rib 47 and the outer rib 48 are respectively received as shown in FIG. The portion 18 is held in contact with the straight surface 18A. In this state, rattling up and down and right and left between the hood portion 12 and the cap 34 (main body portion 32) is restricted, and rattling up and down between the hood portion 12 and the fitting cylinder portion 33 is restricted. The rattling between the male and female connectors 10, 30 is restricted. When the operating lever 50 reaches the fitting position, the bending locking piece 55 of the operating portion 51 is locked to the holding projection 46 of the holding portion 45, whereby the operating lever 50 is held at the fitting position. Further, the male terminal fitting 20 is elastically contacted with the elastic contact piece of the female terminal fitting 40, and the electric wires W connected to the male and female terminal fittings 20 and 40 are connected so as to be conductive.

この後、雌雄両コネクタ10,30がこじられたり、あるいは車両に搭載された状態で車体から伝わる振動等によって各リブ47,48がストレート面18Aの面方向に沿って上下方向や左右方向に位置ずれすることがあり得る。しかしながら、上下リブ47A,47Bの突出端にそれぞれ接触するストレート面18Aは平行であり、左右リブ47C,47Dの突出端にそれぞれ接触するストレート面18Aも平行であり、上下リブ48A,48Bの突出端にそれぞれ接触するストレート面18Aも平行であるから、各リブ47,48の突出端とストレート面18Aとは接触した状態に保持される。したがって、引き続きフード部12とキャップ34(本体部32)との間及びフード部12と嵌合筒部33との間でがたつくことが規制され、雌雄両コネクタ10,30間のがたつきが規制される。   Thereafter, the ribs 47 and 48 are positioned in the vertical and horizontal directions along the surface direction of the straight surface 18A due to vibrations transmitted from the vehicle body when the male and female connectors 10 and 30 are twisted or mounted on the vehicle. It may be displaced. However, the straight surfaces 18A that contact the protruding ends of the upper and lower ribs 47A and 47B are parallel, and the straight surfaces 18A that contact the protruding ends of the left and right ribs 47C and 47D are also parallel, and the protruding ends of the upper and lower ribs 48A and 48B. Since the straight surfaces 18A that are in contact with each other are also parallel, the protruding ends of the ribs 47 and 48 and the straight surfaces 18A are held in contact with each other. Accordingly, rattling between the hood portion 12 and the cap 34 (main body portion 32) and between the hood portion 12 and the fitting tube portion 33 is restricted, and rattling between the male and female connectors 10, 30 is restricted. Is done.

尚、雌雄両コネクタ10,30を離脱させる際は、解除操作部56を指で摘んで撓み係止片55と保持突部46との係止状態を解除して、操作レバー50を嵌合位置から待機位置へと回動させることで、カムピン13とカム溝53のカム作用によってカムピン13がカム溝53の入口へ進み、雌雄両コネクタ10,30が互いに離間する方向に移動する。   When the male and female connectors 10 and 30 are detached, the release operation portion 56 is grasped with a finger to release the engagement state between the bending engagement piece 55 and the holding projection 46, and the operation lever 50 is engaged. The cam pin 13 advances to the entrance of the cam groove 53 by the cam action of the cam pin 13 and the cam groove 53, and the male and female connectors 10, 30 are moved away from each other.

以上のように本実施形態では、各リブ47,48の突出端と接触するストレート面18Aが互いに平行となるようにしたから、雌雄両コネクタ10,30間のがたつきを規制しつつも、各リブ47,48がこれと接触するストレート面18Aの面方向に沿って位置ずれすることが許容される。また、受け部18をフード部12の奥壁側に設けて、雌雄両コネクタ10,30の嵌合完了時にがたつきが規制されるようにしたから、嵌合途上における操作力が小さくて済む。さらに、フード部12の長辺側における両端付近に受け部18を設けたから、フード部12の長辺側が厚肉に形成されることを回避することができる。これらに加えて、既存構造である各ガイド片14,15,16及び各ガイド凹部37,42,43を利用して外側リブ48及び受け部18を設けたから、大きな設計変更を伴うことなく、かつ、全体構成を複雑にすることなく、雌雄両コネクタ10,30間のがたつきを規制することができる。   As described above, in the present embodiment, since the straight surfaces 18A that contact the protruding ends of the ribs 47 and 48 are parallel to each other, the rattling between the male and female connectors 10 and 30 is restricted, The ribs 47 and 48 are allowed to be displaced along the surface direction of the straight surface 18A in contact therewith. In addition, since the receiving portion 18 is provided on the back wall side of the hood portion 12 so that the rattling is restricted when the male and female connectors 10 and 30 are completely fitted, the operation force during the fitting is small. . Further, since the receiving portions 18 are provided in the vicinity of both ends on the long side of the hood portion 12, it is possible to avoid the long side of the hood portion 12 from being formed thick. In addition to these, since the outer rib 48 and the receiving portion 18 are provided using the guide pieces 14, 15, 16 and the guide recesses 37, 42, 43, which are existing structures, without significant design changes, and The rattling between the male and female connectors 10 and 30 can be regulated without complicating the overall configuration.
