次に、図１、及び図４〜図８を参照して雌コネクタ６について説明する。雌コネクタ６は、雌端子７と、雌ハウジング８と、フロントホルダ９とを有する。なお、以下の説明では、雌コネクタ６において、挿抜方向Ｘの雄コネクタ２側を前側といい、その反対側を後側という場合がある。 Next, the female connector 6 will be described with reference to FIGS. 1 and 4 to 8. The female connector 6 has a female terminal 7, a female housing 8, and a front holder 9. In the following description, in the female connector 6, the male connector 2 side in the insertion/removal direction X may be referred to as the front side, and the opposite side may be referred to as the rear side.

雌端子７は、電気導電性を有する金属等によって形成され、基部７０と筒部７４とを有し、雄端子３と電気的に接続可能である。雌端子７は、雌ハウジング８に複数設けてある。 The female terminal 7 is made of an electrically conductive metal or the like, has a base portion 70 and a tubular portion 74, and is electrically connectable to the male terminal 3. A plurality of female terminals 7 are provided on the female housing 8.

この実施形態では、基部７０と、筒部７４とを個別に形成した雌コネクタ６を説明する。基部７０は、円柱状部７１とフランジ部７２と平板状部分７３とを含み、これらが一体で形成される。円柱状部７１が、雌端子７の前側に位置し、平板状部分７３が雌端子７の後側に位置し、フランジ部７２は、挿抜方向Ｘにおいて円柱状部７１と平板状部分７３との間に位置している。これらは、挿抜方向Ｘに沿って延在するように配置してある。雌端子７の平板状部分７３は、電気機器１９に電気的に接続してある。なお、平板状部分７３は、バスバ等の配索材に電気的に接続してもよい。 In this embodiment, the female connector 6 in which the base portion 70 and the tubular portion 74 are individually formed will be described.

The flat plate portion 73 of the female terminal 7 is electrically connected to the electric device 19. The flat plate portion 73 may be electrically connected to a wiring material such as a bus bar.

円柱状部７１の外周面における径方向の寸法は、円筒状の雌端子収容部８３の内周面における径方向の寸法よりも小さい。このため、円柱状部７１を雌端子収容部８３の内部に挿入することが可能である。 The radial dimension of the outer peripheral surface of the cylindrical portion 71 is smaller than the radial dimension of the inner peripheral surface of the cylindrical female terminal accommodating portion 83. Therefore, the cylindrical portion 71 can be inserted into the female terminal accommodating portion 83.

フランジ部７２の外周面における径方向の寸法は、円筒状の雌端子収容部８３の内周面における径方向の寸法よりも大きい。このため、フランジ部７２を雌端子収容部８３の内部に挿入することはできない。 The radial dimension of the outer peripheral surface of the flange portion 72 is larger than the radial dimension of the inner peripheral surface of the cylindrical female terminal accommodating portion 83. Therefore, the flange portion 72 cannot be inserted into the female terminal accommodating portion 83.

筒部７４は、図６に示すように、挿抜方向Ｘに沿って延在する矩形板状部分７５と、複数の矩形板状部分７５を連結する連結部７６とを有し、これらを円柱状の基部７０の周方向に沿って交互に配置して円筒状に形成してある。つまり、基部７０の周方向に沿って、矩形板状部分７５と、隣接する矩形板状部分７５の間に位置する間隙７５ｓとが交互に配置されている。矩形板状部分７５は、固定延在部分７７と、前傾斜部分７８ａと、後傾斜部分７８ｂと、前端部分７９ａと、後端部分７９ｂとを有している。固定延在部分７７は、連結部７６に固定された部分であるとともに、挿抜方向Ｘに沿って直線状に延在する部分である。前傾斜部分７８ａは、固定延在部分７７の前側の端縁から、前方及び径内方向に対してそれぞれ傾斜する態様で延在する部分である。前傾斜部分７８ａを配置した部分では、後方から前方へ向けて筒部７４の径方向の寸法が徐々に小さくなる。後傾斜部分７８ｂは、固定延在部分７７の後側の端縁から、後方及び径内方向に対してそれぞれ傾斜する態様で延在する部分である。後傾斜部分７８ｂを配置した部分では、前方から後方へ向けて筒部７４の径方向の寸法が徐々に小さくなる。前端部分７９ａは、前傾斜部分７８ａの前側の端縁から、前方及び径外方向に対してそれぞれ傾斜する態様で延在する部分である。前端部分７９ａを配置した部分では、後方から前方へ向けて筒部７４の径方向の寸法が徐々に大きくなる。後端部分７９ｂは、後傾斜部分７８ｂの後側の端縁から、後方及び径外方向に対してそれぞれ傾斜する態様で延在する部分である。後端部分７９ｂを配置した部分では、前方から後方へ向けて筒部７４の径方向の寸法が徐々に大きくなる。上述のように形成された筒部７４は、周方向に沿って、矩形板状部分７５と間隙７５ｓとを交互に配置することで弾性変形可能に形成してある。１つの筒部７４は、間隙７５ｓを１４つ有している。 As shown in FIG. 6, the tubular portion 74 has a rectangular plate-shaped portion 75 extending along the insertion/extraction direction X and a connecting portion 76 that connects the plurality of rectangular plate-shaped portions 75, and these are cylindrical. The base portions 70 are alternately arranged along the circumferential direction to form a cylindrical shape. That is, the rectangular plate-shaped portions 75 and the gaps 75s located between the adjacent rectangular plate-shaped portions 75 are alternately arranged along the circumferential direction of the base portion 70. The rectangular plate-shaped portion 75 has a fixed extension portion 77, a front inclined portion 78a, a rear inclined portion 78b, a front end portion 79a, and a rear end portion 79b. The fixed extension portion 77 is a portion that is fixed to the connecting portion 76 and that extends linearly along the insertion/extraction direction X. The front sloping portion 78a is a portion extending from the front edge of the fixed extension portion 77 in such a manner as to incline forward and radially. In the portion where the front inclined portion 78a is arranged, the radial dimension of the cylindrical portion 74 gradually decreases from the rear to the front. The rear inclined portion 78b is a portion that extends from the rear end edge of the fixed extension portion 77 in a manner that it inclines rearward and radially. In the portion where the rear inclined portion 78b is arranged, the radial dimension of the cylindrical portion 74 gradually decreases from the front to the rear. The front end portion 79a is a portion that extends from the front edge of the front inclined portion 78a in a manner inclining to the front and the radially outward direction, respectively. In the portion where the front end portion 79a is arranged, the radial dimension of the tubular portion 74 gradually increases from the rear to the front. The rear end portion 79b is a portion that extends from the rear end edge of the rear inclined portion 78b in a manner inclining rearward and radially outward. In the portion where the rear end portion 79b is arranged, the radial dimension of the tubular portion 74 gradually increases from the front to the rear. The tubular portion 74 formed as described above is elastically deformable by alternately arranging the rectangular plate-shaped portions 75 and the gaps 75s along the circumferential direction. One tubular portion 74 has 14 gaps 75s.

筒部７４の前端部分７９ａの径方向の大きさは、雄端子３の円筒状部分３１の径方向の大きさよりもわずかに小さい。筒部７４の後端部分７９ｂの径方向の大きさは、雌端子７の基部７０の径方向の大きさよりもわずかに小さい。 The radial size of the front end portion 79a of the tubular portion 74 is slightly smaller than the radial size of the cylindrical portion 31 of the male terminal 3. The radial size of the rear end portion 79b of the tubular portion 74 is slightly smaller than the radial size of the base portion 70 of the female terminal 7.

雌端子７を組み立てるには、基部７０の前方に筒部７４を配置する。この状態から、基部７０に対して筒部７４を前方から後方へ移動させる。上述したように、筒部７４は、径方向において弾性変形可能に形成してあり、筒部７４の後端部分７９ｂの径方向の大きさは、基部７０の径方向の大きさよりもわずかに小さい。このため、筒部７４の後端部分７９ｂが基部７０に接触すると、後端部分７９ｂ及び後傾斜部分７８ｂは、拡径し（径方向の寸法が大きくなって）、基部７０に筒部７４が固定されて雌端子７が組み立てられる。 To assemble the female terminal 7, the tubular portion 74 is arranged in front of the base portion 70. From this state, the tubular portion 74 is moved from the front to the rear with respect to the base 70. As described above, the tubular portion 74 is formed to be elastically deformable in the radial direction, and the radial size of the rear end portion 79b of the tubular portion 74 is slightly smaller than the radial size of the base portion 70. .. Therefore, when the rear end portion 79b of the tubular portion 74 comes into contact with the base portion 70, the rear end portion 79b and the rear inclined portion 78b are expanded in diameter (the radial dimension is increased), and the tubular portion 74 is attached to the base portion 70. The female terminal 7 is fixed and assembled.

Both side surfaces of the connecting portion 92 in the first direction Y form the same plane as the outer peripheral surface of the first cylindrical portion 90.

一対の連結部９２は、第１方向Ｙにおいて、径方向の外側から内側へ向けて凹む連結凹部９２ａを有している。連結凹部９２ａは、挿抜方向Ｘにおいて、連結部９２の中間位置に配置してある。このため、一対の連結部９２は、挿抜方向Ｘにおける前方から後方に向けて、第１円筒状部９０から連続する連続部分９２ｂと、連結凹部９２ａと、連結凹部９２ａから径外方向へ突出する爪部９２ｃとそれぞれ有している。 The pair of connecting portions 92 has a connecting recess 92a that is recessed from the outer side to the inner side in the radial direction in the first direction Y. The connecting concave portion 92a is arranged at an intermediate position of the connecting portion 92 in the insertion/removal direction X. For this reason, the pair of connecting portions 92 project from the front in the insertion/removal direction X toward the rear, the continuous portion 92b continuous from the first cylindrical portion 90, the connecting recess 92a, and the connecting recess 92a in the radially outward direction. Each has a claw portion 92c.

連結部９２の第１方向Ｙにおける厚さ寸法は、雌端子収容部８３の切欠８８ａの第１方向Ｙにおける寸法よりも小さく、第１円筒状部９０から連続する連続部分９２ｂを、切欠８８ａに挿入することが可能である。 The thickness dimension of the connecting portion 92 in the first direction Y is smaller than the dimension of the cutout 88a of the female terminal accommodating portion 83 in the first direction Y, and the continuous portion 92b continuous from the first cylindrical portion 90 is formed in the cutout 88a. It is possible to insert.

押圧部９３は、後述する完全嵌合状態において、雄端子３を筒部７４側に押圧して弾性変形させ、雄端子３と雌端子７とを電気的に接続するものである。押圧部９３は、押圧傾斜部９３ａと押圧円筒部９３ｂとを有しており、押圧傾斜部９３ａが押圧部９３の前方側に位置し、押圧円筒部９３ｂが押圧部９３の後方側に位置するように配置してある。押圧傾斜部９３ａの外周面は、第２円筒状部９１の円筒状部分の後端縁から、後方及び径内方向に対してそれぞれ傾斜する態様で延在する（図９参照）。押圧円筒部９３ｂの外周面における径方向の大きさは、雄端子３の円筒状部の径方向の大きさよりもわずかに大きい。 The pressing portion 93 is for electrically connecting the male terminal 3 and the female terminal 7 by pressing the male terminal 3 toward the cylindrical portion 74 side and elastically deforming the male terminal 3 in a completely fitted state described later. The pressing portion 93 has a pressing inclined portion 93a and a pressing cylindrical portion 93b, the pressing inclined portion 93a is located on the front side of the pressing portion 93, and the pressing cylindrical portion 93b is located on the rear side of the pressing portion 93. It is arranged as follows. The outer peripheral surface of the pressing inclined portion 93a extends from the rear end edge of the cylindrical portion of the second cylindrical portion 91 in such a manner as to incline rearward and radially inward (see FIG. 9). The radial size of the outer peripheral surface of the pressing cylindrical portion 93b is slightly larger than the radial size of the cylindrical portion of the male terminal 3.

このような雌コネクタ６を組み立てる時には、先ず、図５に示すように、雌ハウジング８の後方に２つの雌端子７を配置する。この状態から、雌ハウジング８に対して雌端子７を後方から前方へ移動させる。上述したように、円柱状部７１の径方向の寸法は、円筒状の雌端子収容部８３の径方向の寸法よりも小さく、且つ、フランジ部７２の径方向の寸法は、円筒状の雌端子収容部８３の径方向の寸法よりも大きい。このため、雌端子収容部８３の後方側の壁部の端部に、基部７０のフランジ部７２が突き当たり、雌端子７の円柱状部７１及び筒部７４が雌端子収容部８３の内部に配置される。 When assembling such a female connector 6, first, as shown in FIG. 5, two female terminals 7 are arranged behind the female housing 8. From this state, the female terminal 7 is moved from the rear to the front with respect to the female housing 8. As described above, the radial dimension of the columnar portion 71 is smaller than the radial dimension of the cylindrical female terminal accommodating portion 83, and the radial dimension of the flange portion 72 is the cylindrical female terminal. It is larger than the radial dimension of the housing portion 83. Therefore, the flange portion 72 of the base portion 70 abuts against the end portion of the rear wall portion of the female terminal accommodating portion 83, and the cylindrical portion 71 and the cylindrical portion 74 of the female terminal 7 are arranged inside the female terminal accommodating portion 83. To be done.

次に、雌ハウジング８の前方に２つのフロントホルダ９を配置する。この状態から、雌ハウジング８に対してフロントホルダ９を前方から後方へ移動させる。この時、雌端子収容部８３の切欠８８ａに、フロントホルダ９の爪部９２ｃ及び連続部分９２ｂが挿入される。その後、さらに、雌ハウジング８に対してフロントホルダ９を前方から後方へ移動させると、切欠８８ａの端部に、爪部９２ｃが接触する。この接触の後、さらに、雌ハウジング８に対してフロントホルダ９を前方から後方へ移動させると、フロントホルダ９が縮径するとともに、雌端子収容部８３が拡径し、フロントホルダ９の爪部分と、雌端子収容部８３の貫通穴８８ｂとが係合する。また、上述したように、第１円筒状部９０の内周面の径方向の大きさは、雌ハウジング８の雌端子収容部８３の内周面の径方向の大きさよりも小さいため、フロントホルダ９の第１円筒状部９０を、雌端子収容部８３の内部に挿入することはできない。このため、雌端子収容部８３の前方側の壁部の端部に、フロントホルダ９が突き当たり、雌端子収容部８３の前方に、フロントホルダ９の第１円筒状部９０が配置され、雌コネクタ６の組立が終了する。また、この組立状態では、筒部７４の内部に押圧部９３が配置される。 Next, the two front holders 9 are arranged in front of the female housing 8. From this state, the front holder 9 is moved from the front to the rear with respect to the female housing 8. At this time, the claw portion 92c and the continuous portion 92b of the front holder 9 are inserted into the notches 88a of the female terminal accommodating portion 83. Thereafter, when the front holder 9 is further moved from the front to the rear with respect to the female housing 8, the claw portion 92c comes into contact with the end portion of the notch 88a. After this contact, when the front holder 9 is further moved from the front to the rear with respect to the female housing 8, the diameter of the front holder 9 is reduced and the diameter of the female terminal accommodating portion 83 is increased, and the claw portion of the front holder 9 is And the through hole 88b of the female terminal accommodating portion 83 engage with each other. Further, as described above, since the radial size of the inner peripheral surface of the first cylindrical portion 90 is smaller than the radial size of the inner peripheral surface of the female terminal accommodating portion 83 of the female housing 8, the front holder. The first cylindrical portion 90 of 9 cannot be inserted into the female terminal accommodating portion 83. Therefore, the front holder 9 abuts against the end of the front wall portion of the female terminal accommodating portion 83, and the first cylindrical portion 90 of the front holder 9 is arranged in front of the female terminal accommodating portion 83. The assembly of 6 is completed. Further, in this assembled state, the pressing portion 93 is arranged inside the cylindrical portion 74.

コネクタ装置１を組み立てる場合、図１及び図９に示すように、挿抜方向Ｘに沿って、雄コネクタ２と雌コネクタ６とを互いに離れた状態に配置する。この状態から、雄コネクタ２と雌コネクタ６とを互いに近づけ、雄ハウジング４の先端部分４ａを、フード部８４と、雌端子収容部８３の外周面との間に位置するハウジング凹部８０ｂに挿入する。 When assembling the connector device 1, as shown in FIGS. 1 and 9, the male connector 2 and the female connector 6 are arranged in a state of being separated from each other along the insertion/extraction direction X. From this state, the male connector 2 and the female connector 6 are brought close to each other, and the tip portion 4a of the male housing 4 is inserted into the housing recess 80b located between the hood portion 84 and the outer peripheral surface of the female terminal accommodating portion 83. ..

コネクタ装置１では、雄ハウジング４の先端部分４ａをハウジング凹部８０ｂに挿入した後、さらに、雌ハウジング８の内部に、雄ハウジング４の先端部分４ａを挿入する。すると、図１０に示すように、コネクタ装置１では、雌端子７における筒部７４の前端部分７９ａと、雄コネクタ２のキャップ５の被覆外側部分５１ｂとが接触する。図９に示すように、筒部７４の前端部分７９ａは、前傾斜部分７８ａの前側の端縁から、前方及び径外方向に対してそれぞれ傾斜する態様で延在する。また、キャップ５の第１被覆部５１は、被覆内側部分５１ａから、前方から後方へ行くに従って、径方向の寸法が徐々に大きくなるように形成してある。これらによって、図１１に示すように、前傾斜部分７８ａ及び前端部分７９ａが拡径し（筒部７４が弾性変形し）、前端部分７９ａの内部に雄端子３の第１被覆部５１が挿入され、雄ハウジング４の一部が雌ハウジング８の一部に挿入された半嵌合状態となる。 In the connector device 1, after the tip portion 4a of the male housing 4 is inserted into the housing recess 80b, the tip portion 4a of the male housing 4 is further inserted into the female housing 8. Then, as shown in FIG. 10, in the connector device 1, the front end portion 79a of the tubular portion 74 of the female terminal 7 and the covering outer portion 51b of the cap 5 of the male connector 2 come into contact with each other. As shown in FIG. 9, the front end portion 79a of the tubular portion 74 extends from the front end edge of the front inclined portion 78a in a manner inclined with respect to the front direction and the radially outward direction. The first covering portion 51 of the cap 5 is formed such that the radial dimension thereof gradually increases from the covering inner portion 51a toward the rear. As a result, as shown in FIG. 11, the front inclined portion 78a and the front end portion 79a are expanded in diameter (the cylinder portion 74 is elastically deformed), and the first covering portion 51 of the male terminal 3 is inserted into the front end portion 79a. Then, a part of the male housing 4 is inserted into a part of the female housing 8 to be in a semi-fitted state.

筒部７４の前傾斜部分７８ａは、図９に示すように、固定延在部分７７の前側の端縁から、前方及び径内方向に対してそれぞれ傾斜する態様で延在する部分である。筒部７４の前端部分７９ａは、前傾斜部分７８ａの前側の端縁から、前方及び径外方向に対してそれぞれ傾斜する態様で延在する部分である。このため、前傾斜部分７８ａの前端と、前端部分７９ａの後端との間に位置する境界部分７８ｘが、筒部７４において最も径方向の内側に位置し、図１１示すように、境界部分７８ｘが雄端子３の円筒状部分３１の外周面に接触する。 As shown in FIG. 9, the front inclined portion 78a of the cylindrical portion 74 is a portion that extends from the front end edge of the fixed extension portion 77 in a manner that it inclines forward and radially. The front end portion 79a of the tubular portion 74 is a portion that extends from the front end edge of the front inclined portion 78a in a manner inclined toward the front and the radially outward direction. Therefore, the boundary portion 78x located between the front end of the front inclined portion 78a and the rear end of the front end portion 79a is located on the innermost side in the radial direction in the tubular portion 74, and as shown in FIG. 11, the boundary portion 78x. Contacts the outer peripheral surface of the cylindrical portion 31 of the male terminal 3.

半嵌合状態において、さらに、雌ハウジング８の内部に、雄ハウジング４の先端部分４ａをさらに挿入する。すると、第２被覆部５２の内周面と、第２円筒状部９１の内周面とが接触しながら、挿抜方向Ｘに沿って、雌ハウジング８の内部に雄ハウジング４の先端部分４ａがさらに進入する。 In the half-fitted state, the tip portion 4a of the male housing 4 is further inserted into the female housing 8. Then, while the inner peripheral surface of the second covering portion 52 and the inner peripheral surface of the second cylindrical portion 91 are in contact with each other, the distal end portion 4a of the male housing 4 is located inside the female housing 8 along the insertion/removal direction X. Go further.

その後、図１２に示すように、雄端子３の被覆内側部分５１ａが、雄端子３の押圧傾斜部９３ａに接触する。押圧傾斜部９３ａの外周面は、挿抜方向Ｘに沿って延在するように配置してあり、前方側から後方側へ向けて径方向の寸法が徐々に大きくなるように形成してある。よって、この状態から、例えば、図１に示すボルト１７とナット１８とを螺合させることで、さらに雌ハウジング８の内部に、雄ハウジング４の先端部分４ａを挿入する。すると、図１３に示すように、第１被覆部５１が、押圧傾斜部９３ａを乗り越えて押圧円筒部９３ｂに接触して、キャップ５及び雄端子３の円筒状部分３１が拡径する（雄端子３のキャップ５及び円筒状部分３１が第２方向Ｚに沿って弾性変形する）。それによって、円筒状部分３１の外周面が前傾斜部分７８ａを押圧し（雄端子３の円筒状部分３１が筒部７４の前傾斜部分７８ａを押圧し）、雄端子３と雌端子７とが電気的に接続された完全嵌合状態となる。 After that, as shown in FIG. 12, the coated inner portion 51 a of the male terminal 3 contacts the pressing inclined portion 93 a of the male terminal 3. The outer peripheral surface of the pressing inclined portion 93a is arranged so as to extend along the insertion/extraction direction X, and is formed so that the radial dimension gradually increases from the front side toward the rear side. Therefore, from this state, for example, by screwing the bolt 17 and the nut 18 shown in FIG. 1, the tip portion 4a of the male housing 4 is further inserted into the female housing 8. Then, as shown in FIG. 13, the first covering portion 51 rides over the pressing inclined portion 93a and comes into contact with the pressing cylindrical portion 93b, and the cap 5 and the cylindrical portion 31 of the male terminal 3 expand in diameter (male terminal). The cap 5 and the cylindrical portion 31 of 3 are elastically deformed along the second direction Z). Thereby, the outer peripheral surface of the cylindrical portion 31 presses the front inclined portion 78a (the cylindrical portion 31 of the male terminal 3 presses the front inclined portion 78a of the cylindrical portion 74), and the male terminal 3 and the female terminal 7 are separated from each other. It is in a completely fitted state where it is electrically connected.

実施形態に係るコネクタ装置１、及び、ワイヤハーネスＷＨの雌コネクタ６は、雄ハウジング４と雌ハウジング８とを完全嵌合させた完全嵌合状態では、雌端子７を筒部７４側に押圧して弾性変形させ、雄端子３と雌端７子とを電気的に接続する押圧部９３を有する。このため、コネクタ装置１は、完全嵌合状態では、押圧部９３によって雄端子３を雌端子７の筒部７４側に押圧し弾性変形させることで、雄端子３と雌端子７とを適正に電気的に接続することができる。この結果、コネクタ装置１は、組み付け時の作業性が低下するのを抑えることができる。 The connector device 1 according to the embodiment and the female connector 6 of the wire harness WH press the female terminal 7 toward the tubular portion 74 side in a completely fitted state in which the male housing 4 and the female housing 8 are completely fitted. It has a pressing portion 93 which is elastically deformed to electrically connect the male terminal 3 and the female end 7 to each other. Therefore, in the completely fitted state, the connector device 1 presses the male terminal 3 toward the tubular portion 74 side of the female terminal 7 by the pressing portion 93 to elastically deform the male terminal 3 and the female terminal 7 properly. It can be electrically connected. As a result, the connector device 1 can suppress deterioration in workability during assembly.

また、コネクタ装置１の筒部７４は、雄ハウジング４と雌ハウジング８とが半嵌合し、雄端子３が筒部７４の内部に挿入された半嵌合状態では、雄端子３との接触によって弾性変形する。よって、コネクタ装置１は、コネクタ嵌合初期の半嵌合状態において、コネクタ嵌合に要する力を低減することができる。 Further, in the tubular portion 74 of the connector device 1, when the male housing 4 and the female housing 8 are half-fitted and the male terminal 3 is inserted into the tubular portion 74, the male terminal 3 comes into contact with the male terminal 3. Elastically deforms due to. Therefore, the connector device 1 can reduce the force required for connector fitting in the semi-fitted state at the initial stage of connector fitting.

加えて、コネクタ装置１の雌コネクタ６は、雌ハウジング８とは別体で形成され、筒部７４の内周面を覆う電気絶縁性のフロントホルダ９を有し、押圧部９３は、フロントホルダ９に形成してある。このため、上述した作用・効果を奏することに加え、コネクタ装置１の組立・分解の途中で電気導電性の異物が、筒部７４の内部に挿入された時でも、短絡が発生することを抑えることができる。 In addition, the female connector 6 of the connector device 1 is formed separately from the female housing 8 and has an electrically insulating front holder 9 that covers the inner peripheral surface of the tubular portion 74, and the pressing portion 93 is the front holder. 9 is formed. Therefore, in addition to the above-described actions and effects, the occurrence of a short circuit is suppressed even when an electrically conductive foreign substance is inserted into the tubular portion 74 during the assembly/disassembly of the connector device 1. be able to.

さらに、コネクタ装置１では、雄端子３は、雌端子７に対する雄端子３の挿入方向に沿って延在するスリット３５を有し、スリット３５によって弾性変形可能に形成してある。このため、構成を簡単にして、弾性変形が容易な雄端子３を容易に製造することができる。 Further, in the connector device 1, the male terminal 3 has a slit 35 extending along the inserting direction of the male terminal 3 with respect to the female terminal 7, and is formed by the slit 35 so as to be elastically deformable. Therefore, it is possible to easily manufacture the male terminal 3 that is easily elastically deformed with a simple structure.

また、このコネクタ装置１の半嵌合状態において、図１４に示すように、筒部７４の前傾斜部分７８ａは、固定延在部分７７の前側の端縁から、前方及び径内方向に対してそれぞれ傾斜する態様で延在する。筒部７４の前傾斜部分７８ａとキャップ５の被覆外側部分５１ｂとの接触箇所における前傾斜部分７８ａには、前傾斜部分７８ａの延在方向と直交する方向に向かう弾性復元力Ｆ１が発生する。弾性復元力Ｆ１と、挿抜方向Ｘにおける後方から前方へ向かう方向との交差角度をθ１とすると、弾性復元力Ｆ１は、雌端子７及び雄端子３おける径内方向に向かう第１分力Ｆ１ｓｉｎθ１と、前方から後方へ向かう第２分力Ｆ１ｃｏｓθ１とに分けることができる。第１分力Ｆ１ｓｉｎθ１によって筒部７４が雄端子３を径内方向へ押し、第２分力Ｆ１ｃｏｓθ１によって筒部７４が雄端子３を、雌ハウジング８の前方から後方へ向かう方向に押す。よって、半嵌合状態において、弾性復元力Ｆ１によって、雌ハウジング８と雄ハウジング４とを連結した状態に維持することができる。 Further, in the half-fitted state of the connector device 1, as shown in FIG. 14, the front inclined portion 78a of the tubular portion 74 is forward and radially inward from the front end edge of the fixed extension portion 77. Each extends in an inclined manner. An elastic restoring force F1 is generated in the front inclined portion 78a at the contact point between the front inclined portion 78a of the tubular portion 74 and the covering outer side portion 51b of the cap 5, in a direction orthogonal to the extending direction of the front inclined portion 78a. When the intersecting angle between the elastic restoring force F1 and the direction from the rear to the front in the insertion/removal direction X is θ1, the elastic restoring force F1 is the first component force F1sinθ1 toward the radially inner direction of the female terminal 7 and the male terminal 3. , And a second component force F1 cos θ1 from the front to the rear. The cylindrical portion 74 pushes the male terminal 3 radially inward by the first component force F1 sin θ1, and the cylindrical portion 74 pushes the male terminal 3 in the direction from the front of the female housing 8 to the rear by the second component force F1 cos θ1. Therefore, in the semi-fitted state, the elastic restoring force F1 can maintain the female housing 8 and the male housing 4 in a coupled state.

さらに、このコネクタ装置１では、前端部分７９ａと前傾斜部分７８ａとの境界部分７８ｘを超えて、筒部７４の内部に、雄端子３の先端部分を挿入すれば、半嵌合状態を維持することができる。しかも、前端部分７９ａの挿抜方向Ｘの寸法Ｌ１よりも、前傾斜部分７８ａの挿抜方向Ｘの寸法Ｌ２を大きくしてある。よって、半嵌合状態において、雌端子７に対する雄端子３の挿抜方向Ｘに沿って移動を容易にすることができる。これにより、作業内容に応じて雄ハウジング４及び雌ハウジング８を挿抜方向Ｘへ移動させることができ、コネクタ装置１の組立時の作業性を向上することができる。 Further, in this connector device 1, if the tip portion of the male terminal 3 is inserted into the inside of the tubular portion 74 beyond the boundary portion 78x between the front end portion 79a and the front inclined portion 78a, the half-fitted state is maintained. be able to. Moreover, the dimension L2 of the front inclined portion 78a in the insertion/removal direction X is made larger than the dimension L1 of the front end portion 79a in the insertion/removal direction X. Therefore, in the half-fitted state, the male terminal 3 can be easily moved along the insertion/removal direction X with respect to the female terminal 7. Thereby, the male housing 4 and the female housing 8 can be moved in the insertion/removal direction X according to the work content, and the workability at the time of assembling the connector device 1 can be improved.

また、このコネクタ装置１では、図６に示すように、矩形板状部分７５間に位置する間隙７５ｓが１４つである一方、図２に示すように、雄端子３の円筒状部分３１のスリット３５が２つである。雄端子３のスリット３５の数よりも筒部７４の間隙７５ｓの数を多くすることによって、雄端子３を変形させるのに必要とされる力よりも、筒部７４を変形させるのに必要とされる力を小さくしてある。よって、小さな力で、コネクタ装置１を半嵌合状態にすることができる。 Further, in this connector device 1, as shown in FIG. 6, there are 14 gaps 75s located between the rectangular plate-shaped portions 75, while as shown in FIG. 2, slits of the cylindrical portion 31 of the male terminal 3 are formed. There are two 35. By making the number of the gaps 75s of the cylindrical portion 74 larger than the number of the slits 35 of the male terminal 3, it is necessary to deform the cylindrical portion 74 more than the force required to deform the male terminal 3. The force that is applied is reduced. Therefore, the connector device 1 can be brought into the half-fitted state with a small force.

さらに、このコネクタ装置１では、矩形板状部分７５の径方向における厚さ寸法を、雄端子３の円筒状部分３１の径方向における厚さ寸法を小さくしてある。これによって、雄端子３を変形させるのに必要とされる力よりも、筒部７４を変形させるのに必要とされる力が小さくしてある。よって、小さな力で、コネクタ装置１を半嵌合状態にすることができる。 Further, in this connector device 1, the radial thickness of the rectangular plate portion 75 is smaller than the radial thickness of the cylindrical portion 31 of the male terminal 3. As a result, the force required to deform the cylindrical portion 74 is smaller than the force required to deform the male terminal 3. Therefore, the connector device 1 can be brought into the half-fitted state with a small force.

また、このコネクタ装置１では、図１４に示すように、前端部分７９ａの挿抜方向Ｘの寸法Ｌ１よりも、押圧傾斜部９３ａの挿抜方向Ｘの寸法Ｌ３を小さくしてある。また、前傾斜部分７８ａの挿抜方向Ｘの寸法Ｌ２よりも、押圧傾斜部９３ａの挿抜方向Ｘの寸法Ｌ３を小さくしてある。このコネクタ装置１の組み立て時において、雄ハウジング４又は雌ハウジング８の大部分の移動を人の手によって行う。そして、押圧傾斜部９３ａにキャップ５の第１被覆部５１が接触し、その後、キャップ５の第１被覆部５１が押圧傾斜部９３ａを乗り超えるまでの雄ハウジング４または雌ハウジング８の移動のみをボルト１７及びナット１８の締結力によって行う。第１被覆部５１が押圧傾斜部９３ａを乗り越える時には大きな力が必要となる。しかし、このコネクタ装置１によれば、大きな力を必要とする雄ハウジング４または雌ハウジング８の移動距離を短くすることができるため、組立時の作業を容易にすることができる。 Further, in this connector device 1, as shown in FIG. 14, the dimension L3 of the pressing inclined portion 93a in the insertion/extraction direction X is smaller than the dimension L1 of the front end portion 79a in the insertion/extraction direction X. Further, the dimension L3 of the pressing inclined portion 93a in the insertion/removal direction X is smaller than the dimension L2 of the front inclined portion 78a in the insertion/removal direction X. When the connector device 1 is assembled, most of the male housing 4 or the female housing 8 is moved manually. Then, only the movement of the male housing 4 or the female housing 8 until the first covering portion 51 of the cap 5 comes into contact with the pressing inclined portion 93a and then the first covering portion 51 of the cap 5 gets over the pressing inclined portion 93a. It is performed by the fastening force of the bolt 17 and the nut 18. A large force is required when the first covering portion 51 gets over the pressing inclined portion 93a. However, according to this connector device 1, since the moving distance of the male housing 4 or the female housing 8 which requires a large force can be shortened, the work at the time of assembly can be facilitated.

また、このコネクタ装置１の雌ハウジング８は、筒部７４の内周面を覆う電気絶縁性の触指防止部であるフロントホルダ９を含んで構成されている。このため、筒部７４の内部に異物が進入するのを防止することができる。加えて、触指防止部のフロントホルダ９に、完全嵌合状態において、雄端子３を筒部７４側に押圧して雄端子３を弾性変形させる押圧部９３を設けてあるため、押圧部９３をフロントホルダ９と共に雌ハウジング８に取り付けることができる。 Further, the female housing 8 of the connector device 1 is configured to include a front holder 9 that is an electrically insulating touch-finger preventing portion that covers the inner peripheral surface of the tubular portion 74. Therefore, it is possible to prevent foreign matter from entering the inside of the cylindrical portion 74. In addition, since the front holder 9 of the touch-finger preventing portion is provided with the pressing portion 93 that presses the male terminal 3 toward the tubular portion 74 side to elastically deform the male terminal 3 in the completely fitted state, the pressing portion 93 is provided. Can be attached to the female housing 8 together with the front holder 9.

［実施形態２］
次に、コネクタ装置１の実施形態２を図１５を用いて説明する。なお、実施形態２において、実施形態１と同一の構成要素、部分等には同一の符号を付して説明を省略する。図示するように、実施形態２のコネクタ装置１における雌ハウジング８００は、実施形態１のフロントホルダ９と雌ハウジング８とを一体で形成してある。実施形態２のコネクタ装置１のその他の構成は、実施形態１のコネクタ装置１とほぼ同様である。 [Embodiment 2]
Next, a second embodiment of the connector device 1 will be described with reference to FIG. In the second embodiment, the same components and parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. As illustrated, the female housing 800 in the connector device 1 of the second embodiment is formed by integrally forming the front holder 9 and the female housing 8 of the first embodiment. The other configurations of the connector device 1 of the second embodiment are almost the same as those of the connector device 1 of the first embodiment.

The radial size of the second cylindrical portion 911 is smaller than the radial size of the first cylindrical portion 901. In the connector device 1, the first cylindrical portion 901 and the second cylindrical portion 911 differ in radial size, and the tubular portion 74 is inserted from the front of the female housing 800 during disassembly and assembly of the connector device 1. It prevents foreign matter from being inserted inside. The second cylindrical portion 911 is slightly smaller than the radial size of the cylindrical portion 31 of the male terminal 3. The cylindrical portion 31 of the male terminal 3 can be inserted between the first cylindrical portion 901 and the second cylindrical portion 911. The second cylindrical portion 911 covers the inner peripheral surface of the cylindrical portion 74 and functions as a fingertip prevention portion for the female terminal 7. A pressing portion 93 is formed on the outer peripheral surface of the rear end portion of the second cylindrical portion 911. The connecting portion 921 is a portion that connects the first cylindrical portion 901 and the second cylindrical portion 911, and is formed in a substantially rectangular flat plate shape.

このコネクタ装置１によれば、雌ハウジング８００を一体で形成してあるため、部品点数を減少し、コネクタ装置１の組立作業を容易にすることができる。つまり、雌ハウジング８００は、触指防止機能を有するとともに、完全嵌合状態において、雄端子３を筒部７４側に押圧して雄端子３を弾性変形させる押圧部９３を雌ハウジング８００に設けてあるため、雌ハウジング８００に、押圧部９３を有する部品を取り付ける必要がない。 According to this connector device 1, since the female housing 800 is integrally formed, the number of parts can be reduced and the assembling work of the connector device 1 can be facilitated. That is, the female housing 800 has a touch finger prevention function, and is provided with a pressing portion 93 that presses the male terminal 3 toward the cylindrical portion 74 side to elastically deform the male terminal 3 in the completely fitted state. Therefore, it is not necessary to attach a component having the pressing portion 93 to the female housing 800.
