Description

本発明は、嵌合検知コネクタに関するものである。 The present invention relates to a fitting detection connector.

従来、自動車のエアバック装置等に使用されるコネクタとしては、エアバック装置等の点検、組立等の際に誤作動が発生しないようにするために、相手側コネクタとの嵌（かん）合が完了したことを検知する検知スイッチを備えた嵌合検知コネクタが使用されている（例えば、特許文献１参照。）。 Conventionally, as a connector used for an air bag device of an automobile or the like, in order to prevent a malfunction from occurring during inspection, assembly, etc. of the air bag device or the like, the connector is fitted with a mating connector. A fitting detection connector provided with a detection switch for detecting completion is used (for example, see Patent Document 1).

図９は従来の嵌合検知コネクタを示す断面図である。 FIG. 9 is a cross-sectional view showing a conventional fitting detection connector.

図において、３０１は雄側コネクタのハウジングであり、複数の雄側端子３０２が取付けられている。また、３０３は雌側コネクタのハウジングであり、前記雄側端子３０２と接続する雌側端子３０４が取付けられている。 In the figure, reference numeral 301 denotes a male connector housing to which a plurality of male terminals 302 are attached. Reference numeral 303 denotes a female connector housing to which a female terminal 304 connected to the male terminal 302 is attached.

そして、前記雌側コネクタのハウジング３０３の凹部には、金属製の可撓（とう）ロック片３０５が取付けられている。該可撓ロック片３０５は、後端部（図における右端部）がハウジング３０３に固着され、前端部（図における左端部）が上下方向に変位可能となっている。そして、前端部には、オペレータが手指等によって操作する摘み部３０５ａが形成され、該摘み部３０５ａの後方部分には上下方向に貫通する係合孔（こう）３０５ｂが形成されている。 A metal flexible lock piece 305 is attached to the recess of the housing 303 of the female connector. The flexible lock piece 305 has a rear end (right end in the figure) fixed to the housing 303, and a front end (left end in the figure) can be displaced in the vertical direction. At the front end, a knob portion 305a that is operated by an operator with a finger or the like is formed, and an engaging hole (cut) 305b penetrating in the vertical direction is formed at a rear portion of the knob portion 305a.

一方、前記雄側コネクタのハウジング３０１の天井面には、前記係合孔３０５ｂと係合する係合リブ３０６が形成され、さらに、該係合リブ３０６の左右（図における手前側及び奥側）には嵌合検知用電極３０７が各々配設されている。 On the other hand, an engagement rib 306 that engages with the engagement hole 305b is formed on the ceiling surface of the housing 301 of the male connector, and further, left and right (front side and back side in the figure) of the engagement rib 306. Are fitted with fitting detection electrodes 307, respectively.

そして、ハウジング３０３がハウジング３０１内に挿入され、雄側コネクタと雌側コネクタとの嵌合が完了すると、係合孔３０５ｂに係合リブ３０６が入込んで可撓ロック片３０５がロックされ、雄側コネクタと雌側コネクタとの嵌合の解除が防止される。また、可撓ロック片３０５がそれ自体のばね性によってハウジング３０１の天井面に押圧し、係合リブ３０６の左右に配設された嵌合検知用電極３０７と接触する。これにより、左右の嵌合検知用電極３０７が可撓ロック片３０５を介して互いに導通し、雄側コネクタと雌側コネクタとの嵌合が完了したことが、嵌合検知用電極３０７に接続された検知装置によって検知される。
特開平６−３１０２０９号公報 When the housing 303 is inserted into the housing 301 and the fitting of the male connector and the female connector is completed, the engaging rib 306 is inserted into the engaging hole 305b, and the flexible lock piece 305 is locked. Release of the fitting between the side connector and the female connector is prevented. Further, the flexible lock piece 305 presses against the ceiling surface of the housing 301 by its own spring property, and comes into contact with the fitting detection electrodes 307 arranged on the left and right sides of the engagement rib 306. As a result, the left and right fitting detection electrodes 307 are electrically connected to each other via the flexible lock piece 305, and the fitting of the male connector and the female connector is completed is connected to the fitting detection electrode 307. Detected by a detection device.

しかしながら、前記従来の嵌合検知コネクタにおいては、雄側コネクタと雌側コネクタとを嵌合させる際及び嵌合を解除する際に、可撓ロック片３０５全体を一体的に撓（たわ）ませる必要があるので、可撓ロック片３０５を撓ませるための荷重が大きくなり、操作性が悪化してしまう。また、可撓ロック片３０５が係合リブ３０６の左右に配設された嵌合検知用電極３０７と接触することによって嵌合を検知するようになっているので、雄側コネクタと雌側コネクタとの嵌合状態にがたつきが発生して、ハウジング３０３がハウジング３０１内に挿入される度合が幅方向において相違すると、可撓ロック片３０５と左右いずれかの嵌合検知用電極３０７との接触が不確実になり、嵌合検知が不安定になってしまう。 However, in the conventional fitting detection connector, when the male connector and the female connector are fitted to each other and when the fitting is released, the entire flexible lock piece 305 is bent (flipped) integrally. Since it is necessary, the load for bending the flexible lock piece 305 is increased, and the operability is deteriorated. Further, since the flexible lock piece 305 comes into contact with the fitting detection electrodes 307 disposed on the left and right of the engaging rib 306, the fitting is detected. If the degree of engagement of the housing 303 and the degree of insertion of the housing 303 into the housing 301 differ in the width direction, the contact between the flexible lock piece 305 and the left or right fitting detection electrode 307 Becomes uncertain, and the fitting detection becomes unstable.

It is a principal part expansion perspective view of the 2nd connector in embodiment of invention.

図３及び４に示されるように、ロック部材２１の本体部２２は、嵌合方向に延在する可動部２２ａ、該可動部２２ａとほぼ平行に延在する固定部２２ｅ、及び、前記可動部２２ａと固定部２２ｅとを折返すように接続する湾曲部２２ｂを備え、断面がヘアピン状又はＵ字状となっている。そして、前記固定部２２ｅは、ロック部材収容凹部１４を横断するロック部材固定桟部１４ｂと第１ハウジング１２の上壁との間隙（げき）に挿入されて上下方向に移動不能に固定されている。なお、前記固定部２２ｅの後半部分には切起し部２２ｆが形成され、該切起し部２２ｆがロック部材固定桟部１４ｂに当接することによって、固定部２２ｅは嵌合方向に移動不能となっている。このロック部材固定桟部１４ｂと湾曲部２２ｂ及び後述の湾曲部２６ａの内側は、本体部２２及び第１可動接触部２６が上下へ撓むことが可能なほどの空隙が形成されている。 3 and 4, the main body portion 22 of the lock member 21 includes a movable portion 22a extending in the fitting direction, a fixed portion 22e extending substantially parallel to the movable portion 22a, and the movable portion. A curved portion 22b that connects the 22a and the fixing portion 22e so as to be folded back is provided, and the cross-section is a hairpin shape or a U-shape. The fixing portion 22e is inserted into a gap between the lock member fixing bar portion 14b traversing the lock member housing recess 14 and the upper wall of the first housing 12, and is fixed so as not to move in the vertical direction. . Note that a cut-and-raised portion 22f is formed in the latter half of the fixed portion 22e, and the cut-and-raised portion 22f comes into contact with the lock member fixing bar portion 14b, so that the fixed portion 22e cannot move in the fitting direction. It has become. Inside the lock member fixing bar portion 14b, the bending portion 22b, and the bending portion 26a described later, a gap is formed so that the main body portion 22 and the first movable contact portion 26 can be bent up and down.

また、前記可動部２２ａの後端、すなわち、自由端には、傾斜部２２ｄを介して、上段部２２ｃが接続されている。該上段部２２ｃは、前記可動部２２ａとほぼ平行に延在するが、前記傾斜部２２ｄを介することによって生じた段差により、可動部２２ａよりも上方に位置する。なお、前記操作部２５は、上段部２２ｃの後端、すなわち、自由端に接続されている。また、前記係合孔２３及び第２可動接触部２４は上段部２２ｃに位置する。 Further, an upper stage portion 22c is connected to a rear end of the movable portion 22a, that is, a free end via an inclined portion 22d. The upper step portion 22c extends substantially parallel to the movable portion 22a, but is positioned above the movable portion 22a due to a step formed by the inclined portion 22d. The operation unit 25 is connected to the rear end of the upper step portion 22c, that is, the free end. The engagement hole 23 and the second movable contact portion 24 are located in the upper step portion 22c.

図示される例において、本体部２２を厚さ方向に貫通するスリットによって画定された第１可動接触部２６は、可動部２２ａ、湾曲部２２ｂ及び固定部２２ｅに亘（わた）って形成されている。すなわち、第１可動接触部２６の両側を画定するスリットは、可動部２２ａから湾曲部２２ｂを通って固定部２２ｅにまで亘る範囲に形成されている。これにより、前記第１可動接触部２６は、一端が固定部２２ｅに接続され、湾曲部２２ｂと同様の断面形状を備える湾曲部２６ａを含み、前記本体部２２とは独立に上下方向に弾性的に変位可能な部材となっている。一方、前記本体部２２における可動部２２ａ、傾斜部２２ｄ及び上段部２２ｃも、前記第１可動接触部２６とは独立に上下方向に弾性的に変位可能な部材となっている。そのため、本体部２２を撓ませて可動部２２ａ、傾斜部２２ｄ及び上段部２２ｃを上下方向に変位させるために必要な荷重は、第１可動接触部２６が本体部２２と一体化されているものと比較して、低減される。 In the illustrated example, the first movable contact portion 26 defined by a slit that penetrates the main body portion 22 in the thickness direction is formed across the movable portion 22a, the curved portion 22b, and the fixed portion 22e. Yes. That is, the slits defining both sides of the first movable contact portion 26 are formed in a range extending from the movable portion 22a to the fixed portion 22e through the curved portion 22b. Accordingly, the first movable contact portion 26 includes a curved portion 26a having one end connected to the fixed portion 22e and having the same cross-sectional shape as the curved portion 22b, and is elastic in the vertical direction independently of the main body portion 22. This is a displaceable member. On the other hand, the movable portion 22a, the inclined portion 22d, and the upper step portion 22c in the main body portion 22 are members that can be elastically displaced in the vertical direction independently of the first movable contact portion 26. Therefore, the load required to bend the main body portion 22 and displace the movable portion 22a, the inclined portion 22d and the upper step portion 22c in the vertical direction is such that the first movable contact portion 26 is integrated with the main body portion 22. Compared to

なお、前記スリットの形成される範囲は適宜変更することができる。すなわち、第１可動接触部２６の長さは適宜変更することができる。前記スリットは、図示される例において、固定部２２ｅにおける湾曲部２２ｂとの接合部から開始して可動部２２ａの中央付近にまで延在するようになっているが、固定部２２ｅにおけるより後方（図４における右方）から開始するようにしてもよいし、湾曲部２２ｂの途中から開始するようにしてもよい。なお、第１可動接触部２６の幅も適宜変更することができる。すなわち、スリットは第１コネクタ１１が第２コネクタ５１に嵌合されるとき、第１可動接触部２６が第１嵌合検知端子６４に接した際に、その後端側（接触凸部２６ｂ側）が下方へ撓むよう形成されていればよい。 In addition, the range in which the slit is formed can be changed as appropriate. That is, the length of the 1st movable contact part 26 can be changed suitably. In the illustrated example, the slit starts from the joint portion of the fixed portion 22e with the curved portion 22b and extends to the vicinity of the center of the movable portion 22a. You may make it start from the right side in FIG. 4, and may start from the middle of the bending part 22b. In addition, the width | variety of the 1st movable contact part 26 can also be changed suitably. That is, when the first connector 11 is fitted to the second connector 51 and the first movable contact portion 26 contacts the first fitting detection terminal 64, the slit is located at the rear end side (contact convex portion 26b side). Should just be formed to bend downward.

また、第２可動接触部２４は、図示される例において、上段部２２ｃの上面から上方に突出するように形成されているが、必ずしも上方に突出するものである必要はなく、例えば、平板状のものであってもよい。さらに、接触凸部２６ｂも、必要に応じて省略することができる。 In the illustrated example, the second movable contact portion 24 is formed so as to protrude upward from the upper surface of the upper step portion 22c. However, the second movable contact portion 24 is not necessarily required to protrude upward. It may be. Furthermore, the contact convex part 26b can also be abbreviate | omitted as needed.

図４に示されるように、第１ハウジング１２内には、嵌合方向に延在するように形成された貫通孔である端子収容孔１３が形成されている。なお、該端子収容孔１３において、第１ハウジング１２の嵌合端（図４における左端）に形成された相手側端子挿入開口１３ａは、第２端子７１に適合させて、他の部分よりも小径となっている。また、端子収容孔１３の途中には、内部に収容された第１端子３２を固定する固定部材１５が、上下方向に移動可能に配設されている。 As shown in FIG. 4, a terminal housing hole 13 which is a through hole formed so as to extend in the fitting direction is formed in the first housing 12. In the terminal accommodating hole 13, the mating terminal insertion opening 13a formed at the fitting end (left end in FIG. 4) of the first housing 12 is adapted to the second terminal 71 and has a smaller diameter than other portions. It has become. A fixing member 15 for fixing the first terminal 32 accommodated in the terminal accommodating hole 13 is disposed in the middle of the terminal accommodating hole 13 so as to be movable in the vertical direction.

図５に示されるように、第２ハウジング５２の相手側コネクタ収容凹部５４には、端子支持部５５から延出する第２端子７１の先端が配設されている。また、前記相手側コネクタ収容凹部５４の天井面には、下方に向けて突出し嵌合方向に延在する検知端子支持部６１が一体的に形成されている。さらに、前記相手側コネクタ収容凹部５４の天井面の嵌合端側、すなわち、端子支持部５５と反対側の端部には、下方に向けて突出する被ロック部材としての係合突起６２が一体的に形成されている。なお、該係合突起６２の嵌合端下側の角部には傾斜部６２ａが形成され、該傾斜部６２ａの傾斜は、ロック部材２１の本体部２２の傾斜部２２ｄの傾斜とほぼ対応する。そして、前記相手側コネクタ収容凹部５４の天井面における検知端子支持部６１と係合突起６２との間には、第２ハウジング５２の上壁を厚さ方向に貫通する第２固定接触部収容凹部６３が形成されている。なお、前記検知端子支持部６１、係合突起６２及び第２固定接触部収容凹部６３は、各々の嵌合方向に延在する中心軸が一致するように配列されている。 As shown in FIG. 5, the distal end of the second terminal 71 extending from the terminal support portion 55 is disposed in the mating connector housing recess 54 of the second housing 52. In addition, a detection terminal support 61 that protrudes downward and extends in the fitting direction is integrally formed on the ceiling surface of the mating connector housing recess 54. Further, an engagement protrusion 62 as a member to be locked projecting downward is integrally formed on the fitting end side of the ceiling surface of the mating connector housing recess 54, that is, the end opposite to the terminal support portion 55. Is formed. An inclined portion 62 a is formed at the corner portion below the fitting end of the engaging protrusion 62, and the inclination of the inclined portion 62 a substantially corresponds to the inclination of the inclined portion 22 d of the main body portion 22 of the lock member 21. . And between the detection terminal support part 61 and the engagement protrusion 62 in the ceiling surface of the said other party connector accommodation recessed part 54, the 2nd fixed contact part accommodation recessed part which penetrates the upper wall of the 2nd housing 52 in thickness direction 63 is formed. The detection terminal support 61, the engagement protrusion 62, and the second fixed contact portion receiving recess 63 are arranged so that the central axes extending in the respective fitting directions coincide with each other.

そして、前記検知端子支持部６１の下面には、第１嵌合検知端子６４の一部が露出し、ロック部材２１の第１可動接触部２６と接触する第１固定接触部６４ａとして機能する。該第１固定接触部６４ａの嵌合方向に延在する中心軸は、検知端子支持部６１の中心軸と一致する。また、前記第２固定接触部収容凹部６３内には、第２嵌合検知端子６５の一部が露出し、ロック部材２１の第２可動接触部２４と接触する第２固定接触部６５ａとして機能する。該第２固定接触部６５ａの嵌合方向に延在する中心軸は、第２固定接触部収容凹部６３の中心軸と一致する。なお、前記第１固定接触部６４ａは第２固定接触部６５ａよりも低い位置に存し、第１固定接触部６４ａと第２固定接触部６５ａとの上下方向の位置の差は、前記第１可動接触部２６と第２可動接触部２４との上下方向の位置の差にほぼ対応する。 A part of the first fitting detection terminal 64 is exposed on the lower surface of the detection terminal support portion 61 and functions as a first fixed contact portion 64 a that contacts the first movable contact portion 26 of the lock member 21. The central axis extending in the fitting direction of the first fixed contact portion 64 a coincides with the central axis of the detection terminal support portion 61. In addition, a part of the second fitting detection terminal 65 is exposed in the second fixed contact portion accommodating recess 63 and functions as a second fixed contact portion 65 a that contacts the second movable contact portion 24 of the lock member 21. To do. The central axis extending in the fitting direction of the second fixed contact portion 65 a coincides with the central axis of the second fixed contact portion receiving recess 63. The first fixed contact portion 64a is located at a position lower than the second fixed contact portion 65a, and the vertical position difference between the first fixed contact portion 64a and the second fixed contact portion 65a is the first fixed contact portion 65a. This substantially corresponds to the difference in the vertical position between the movable contact portion 26 and the second movable contact portion 24.

また、第２ハウジング５２の整列板５７からは、第２端子７１の脚部７１ａが下方に向けて延出する。該脚部７１ａは、例えば、第２コネクタ５１を図示されない基板に実装する場合には、該基板に形成されたスルーホールに挿入されてはんだ付等によって固定され、基板の導電トレースと接続される。また、取付用突起５６は、前記基板に形成された取付用孔（あな）等に挿入される。さらに、前記基板には、第１コネクタ１１と第２コネクタ５１との嵌合を検知するための図示されない検知装置が接続され、前記第１嵌合検知端子６４及び第２嵌合検知端子６５は前記検知装置に接続される。そして、該検知装置は、前記第１嵌合検知端子６４と第２嵌合検知端子６５とが互いに導通状態になったことによって、第１コネクタ１１と第２コネクタ５１とが嵌合したことを検知する。 Further, the leg portion 71 a of the second terminal 71 extends downward from the alignment plate 57 of the second housing 52. For example, when the second connector 51 is mounted on a board (not shown), the leg 71a is inserted into a through hole formed in the board and fixed by soldering or the like, and is connected to a conductive trace of the board. . The mounting protrusion 56 is inserted into a mounting hole formed on the substrate. Further, a detection device (not shown) for detecting the fitting between the first connector 11 and the second connector 51 is connected to the substrate, and the first fitting detection terminal 64 and the second fitting detection terminal 65 are connected to each other. Connected to the detection device. Then, the detection device detects that the first connector 11 and the second connector 51 have been fitted by the first fitting detection terminal 64 and the second fitting detection terminal 65 being in a conductive state. Detect.

次に、前記第１コネクタ１１と第２コネクタ５１とを嵌合する動作について説明する。 Next, an operation for fitting the first connector 11 and the second connector 51 will be described.

図６は本発明の実施の形態における嵌合検知コネクタの断面図であり第１コネクタと第２コネクタとを嵌合する途中の第１の状態を示す図、図７は本発明の実施の形態における嵌合検知コネクタの要部断面図であり第１コネクタと第２コネクタとを嵌合する途中の第２の状態を示す図、図８は本発明の実施の形態における嵌合検知コネクタの要部断面図であり第１コネクタと第２コネクタとの嵌合が完了した状態を示す図である。 FIG. 6 is a cross-sectional view of the fitting detection connector according to the embodiment of the present invention, and shows a first state in the middle of fitting the first connector and the second connector, and FIG. 7 shows the embodiment of the present invention. FIG. 8 is a cross-sectional view of a main part of the fitting detection connector in FIG. 2, showing a second state in the middle of fitting the first connector and the second connector, and FIG. 8 is a diagram of the fitting detection connector in the embodiment of the present invention. It is a fragmentary sectional view and is a figure showing the state where fitting with the 1st connector and the 2nd connector was completed.

まず、オペレータは、手指等によって、図２に示されるように、第１コネクタ１１と第２コネクタ５１とを互いの嵌合面が向合うような姿勢として相互に接近させる。そして、第１コネクタ１１の第１ハウジング１２を、図１に示されるように、第２コネクタ５１の相手側コネクタ収容凹部５４内に挿入する。 First, as shown in FIG. 2, the operator causes the first connector 11 and the second connector 51 to approach each other in such a posture that their mating surfaces face each other. Then, the first housing 12 of the first connector 11 is inserted into the mating connector housing recess 54 of the second connector 51 as shown in FIG.

これにより、図６に示されるように、第２コネクタ５１の第２端子７１の先端が第１ハウジング１２の相手側端子挿入開口１３ａから端子収容孔１３内に進入し、該端子収容孔１３内に固定されている第１端子３２との接続が開始される。なお、図６に示される状態では、ロック部材２１は、まだ第２ハウジング５２の係合突起６２と当接していない。 Thereby, as shown in FIG. 6, the tip of the second terminal 71 of the second connector 51 enters the terminal receiving hole 13 from the mating terminal insertion opening 13 a of the first housing 12, and the terminal receiving hole 13 The connection with the first terminal 32 fixed to is started. In the state shown in FIG. 6, the lock member 21 has not yet come into contact with the engagement protrusion 62 of the second housing 52.

続いて、第１コネクタ１１と第２コネクタ５１とを更に近付けて、第１ハウジング１２を相手側コネクタ収容凹部５４内の更に奥に進入させると、図７に示されるように、ロック部材２１の本体部２２の上面が、相手側コネクタ収容凹部５４の天井面から下方に向けて突出する係合突起６２と当接する。この場合、ロック部材２１が第１ハウジング１２とともに、図７における左方に進行すると、まず、本体部２２の傾斜部２２ｄが、係合突起６２の傾斜部６２ａと当接することによって、下方に押下げられる。なお、前記本体部２２の傾斜部２２ｄの傾斜が前記係合突起６２の傾斜部６２ａの傾斜とほぼ対応しているので、本体部２２は、下方に押下げられつつ、スムーズに図７における左方に進行することができる。 Subsequently, when the first connector 11 and the second connector 51 are brought closer to each other and the first housing 12 is further moved into the mating connector housing recess 54, as shown in FIG. The upper surface of the main body portion 22 comes into contact with an engagement protrusion 62 that protrudes downward from the ceiling surface of the mating connector housing recess 54. In this case, when the lock member 21 moves to the left in FIG. 7 together with the first housing 12, first, the inclined portion 22 d of the main body portion 22 is pressed downward by contacting the inclined portion 62 a of the engaging protrusion 62. Be lowered. Since the inclination of the inclined portion 22d of the main body portion 22 substantially corresponds to the inclination of the inclined portion 62a of the engaging projection 62, the main body portion 22 is smoothly pushed down and left smoothly in FIG. Can progress towards.

そして、前記係合突起６２は、相対的に本体部２２の傾斜部２２ｄを乗越えて上段部２２ｃの上面に当接し、上段部２２ｃを下方に押下げる。これにより、本体部２２は、主として湾曲部２２ｂが弾性的に変形し、可動部２２ａ、傾斜部２２ｄ及び上段部２２ｃが下方に弾性的に変位する。なお、上段部２２ｃの自由端に接続された操作部２５も下方に弾性的に変位する。この場合、前記可動部２２ａ、傾斜部２２ｄ及び上段部２２ｃは、第１可動接触部２６とは独立に上下方向に弾性的に変位可能となっているので、比較的小さな力を受けても、下方に弾性的に変位する。したがって、オペレータは、比較的小さな力によって、第１ハウジング１２を相手側コネクタ収容凹部５４内の奥に進入させることができる。 Then, the engaging protrusion 62 relatively gets over the inclined portion 22d of the main body portion 22 and comes into contact with the upper surface of the upper step portion 22c, and pushes the upper step portion 22c downward. Thereby, as for the main-body part 22, the curved part 22b mainly deform | transforms elastically, and the movable part 22a, the inclination part 22d, and the upper step part 22c are elastically displaced below. Note that the operating portion 25 connected to the free end of the upper step portion 22c is also elastically displaced downward. In this case, the movable portion 22a, the inclined portion 22d, and the upper step portion 22c can be elastically displaced in the vertical direction independently of the first movable contact portion 26, so even if a relatively small force is received, It is elastically displaced downward. Accordingly, the operator can cause the first housing 12 to enter the back of the mating connector housing recess 54 with a relatively small force.

一方、第１可動接触部２６は、図７に示されるように、相手側コネクタ収容凹部５４の天井面から下方に向けて突出する検知端子支持部６１の下面に露出する第１嵌合検知端子６４の第１固定接触部６４ａと接触する。この場合、接触凸部２６ｂが第１固定接触部６４ａと当接することによって、第１可動接触部２６は、主として湾曲部２６ａが弾性的に変形し、下方に弾性的に変位する。なお、前記第１可動接触部２６は、本体部２２とは独立に上下方向に弾性的に変位可能となっているので、比較的小さな力を受けても、下方に弾性的に変位する。したがって、オペレータは、比較的小さな力によって、第１ハウジング１２を相手側コネクタ収容凹部５４内の奥に進入させることができる。すなわち、本件発明のように、第１嵌合検知端子６４が、コネクタの先頭で撓みの支点となる位置の近くでロック部材２１と接触し、これを撓ませようとする場合、前記第１可動接触部２６と本体部２２とが一体で一致して変位する構造であると、前記第１嵌合検知端子６４はロック部材２１全体を撓ませることとなるので、前記第１嵌合検知端子６４がロック部材２１を撓ませる力、つまり、コネクタを進入させる際の抵抗力が大きくなるが、スリットにより第１可動接触部２６を本体部２２に対して独立して動くようにすることによって比較的小さな力によって進入させることができる。また、前記第１可動接触部２６は、本体部２２の変位に影響されることがなく、それ自体の備えるばね性によって接触凸部２６ｂが第１固定接触部６４ａに弾性的に押付けられるので、安定的に第１固定接触部６４ａとの接触状態を維持することができる。 On the other hand, as shown in FIG. 7, the first movable contact portion 26 is a first fitting detection terminal exposed on the lower surface of the detection terminal support portion 61 protruding downward from the ceiling surface of the mating connector housing recess 54. 64 first fixed contact portions 64a come into contact. In this case, when the contact convex part 26b contacts the first fixed contact part 64a, the curved part 26a of the first movable contact part 26 is mainly elastically deformed and elastically displaced downward. Since the first movable contact portion 26 can be elastically displaced in the vertical direction independently of the main body portion 22, even when a relatively small force is applied, the first movable contact portion 26 is elastically displaced downward. Accordingly, the operator can cause the first housing 12 to enter the back of the mating connector housing recess 54 with a relatively small force. That is, as in the present invention, when the first fitting detection terminal 64 is in contact with the lock member 21 near the position serving as a fulcrum of bending at the top of the connector and is going to bend, the first movable If the contact portion 26 and the main body portion 22 have a structure in which the contact portion 26 and the main body portion 22 are integrally aligned and displaced, the first fitting detection terminal 64 bends the entire lock member 21, and thus the first fitting detection terminal 64. The bending force of the locking member 21, that is, the resistance force when the connector is inserted, is increased, but the first movable contact portion 26 can be moved independently with respect to the main body portion 22 by the slit. It can be entered with a small force. In addition, the first movable contact portion 26 is not affected by the displacement of the main body portion 22, and the contact convex portion 26b is elastically pressed against the first fixed contact portion 64a by its own springiness. The contact state with the first fixed contact portion 64a can be stably maintained.

続いて、第１ハウジング１２を相手側コネクタ収容凹部５４内の更に奥に進入させると、図８に示されるように、第１コネクタ１１と第２コネクタ５１との嵌合が完了する。この場合、ロック部材２１が第１ハウジング１２とともに、図８における左方に進行すると、係合突起６２は、相対的に本体部２２の上段部２２ｃの上面に沿って操作部２５の方に移動し、係合孔２３内に進入して係合する。すると、本体部２２は、主として湾曲部２２ｂが弾性的に元の姿勢に復帰しようとするばね性によって、可動部２２ａ、傾斜部２２ｄ及び上段部２２ｃが上方に弾性的に変位する。 Subsequently, when the first housing 12 is further moved into the mating connector housing recess 54, the fitting of the first connector 11 and the second connector 51 is completed as shown in FIG. In this case, when the lock member 21 moves to the left in FIG. 8 together with the first housing 12, the engagement protrusion 62 relatively moves toward the operation portion 25 along the upper surface of the upper step portion 22 c of the main body portion 22. Then, it enters into the engagement hole 23 and engages. Then, in the main body portion 22, the movable portion 22a, the inclined portion 22d, and the upper step portion 22c are elastically displaced upward mainly due to the spring property that the curved portion 22b tends to return to the original posture.

これにより、係合突起６２は、相対的に係合孔２３内により深く進入し、より確実に係合する。そのため、第１コネクタ１１と第２コネクタ５１とは嵌合された状態でロックされ、嵌合の不要な解除が防止される。 As a result, the engagement protrusion 62 relatively deeply enters the engagement hole 23 and engages more securely. Therefore, the first connector 11 and the second connector 51 are locked in a fitted state, and unnecessary release of the fitting is prevented.

また、上段部２２ｃの上面に配設された第２可動接触部２４は、第２固定接触部収容凹部６３内に進入し、該第２固定接触部収容凹部６３内に露出する第２嵌合検知端子６５の第２固定接触部６５ａと接触する。この場合、第２可動接触部２４は、本体部２２のばね性によって第２固定接触部６５ａに弾性的に押付けられるので、安定的に第２固定接触部６５ａとの接触状態を維持することができる。なお、前記第２可動接触部２４及び第２固定接触部６５ａは、電気的接触抵抗を低減するために、少なくとも相手側と接触する部分に金めっきが施されていることが望ましい。 In addition, the second movable contact portion 24 disposed on the upper surface of the upper step portion 22 c enters the second fixed contact portion receiving recess 63 and is exposed in the second fixed contact portion receiving recess 63. It contacts the second fixed contact portion 65a of the detection terminal 65. In this case, since the second movable contact portion 24 is elastically pressed against the second fixed contact portion 65a by the spring property of the main body portion 22, the contact state with the second fixed contact portion 65a can be stably maintained. it can. In addition, as for the said 2nd movable contact part 24 and the 2nd fixed contact part 65a, in order to reduce an electrical contact resistance, it is desirable that the gold plating is given to the part which contacts the other party at least.

一方、第１可動接触部２６は、接触凸部２６ｂが第１嵌合検知端子６４の第１固定接触部６４ａに弾性的に押付けられて接触している状態を維持しながら、すなわち、前記第１固定接触部６４ａを擦りながら移動し、図８に示されるような位置にまで進行する。そのため、拭（ふき）取り効果、すなわち、ワイピング効果が生じ、前記接触凸部２６ｂ及び第１固定接触部６４ａに付着した不純物等の電気的な導通を阻害する物質がワイピングによって除去される。これにより、第１可動接触部２６と第１固定接触部６４ａとの電気的接触抵抗が低減され、電気的な導通が確実なものとなる。また、ワイピングによって電気的接触抵抗を低減することができるので、第１可動接触部２６及び第１固定接触部６４ａには、例えば、錫（すず）めっき等の金めっきよりコストの低いめっきを施すだけで、十分に低い電気的接触抵抗を得ることができる。 On the other hand, the first movable contact portion 26 maintains the state in which the contact convex portion 26b is elastically pressed and in contact with the first fixed contact portion 64a of the first fitting detection terminal 64, that is, the first movable contact portion 26b. 1 Moves while rubbing the fixed contact portion 64a, and proceeds to a position as shown in FIG. Therefore, a wiping effect, that is, a wiping effect is generated, and substances that obstruct electrical conduction such as impurities adhering to the contact convex portion 26b and the first fixed contact portion 64a are removed by wiping. Thereby, the electrical contact resistance between the first movable contact portion 26 and the first fixed contact portion 64a is reduced, and electrical conduction is ensured. Further, since the electrical contact resistance can be reduced by wiping, the first movable contact portion 26 and the first fixed contact portion 64a are plated at a lower cost than gold plating such as tin (tin) plating, for example. Only a sufficiently low electrical contact resistance can be obtained.

このように、第１コネクタ１１と第２コネクタ５１との嵌合が完了すると、第１可動接触部２６が第１固定接触部６４ａと接触するとともに、第２可動接触部２４が第２固定接触部６５ａと接触するので、第１嵌合検知端子６４と第２嵌合検知端子６５とはロック部材２１を介して導通状態となる。そして、検知装置は、前記第１嵌合検知端子６４と第２嵌合検知端子６５とが互いに導通状態になったことによって、第１コネクタ１１と第２コネクタ５１とが嵌合したことを検知する。 Thus, when the fitting between the first connector 11 and the second connector 51 is completed, the first movable contact portion 26 comes into contact with the first fixed contact portion 64a, and the second movable contact portion 24 comes into the second fixed contact. Since it contacts the part 65 a, the first fitting detection terminal 64 and the second fitting detection terminal 65 are in a conductive state via the lock member 21. Then, the detection device detects that the first connector 11 and the second connector 51 are engaged with each other when the first fitting detection terminal 64 and the second fitting detection terminal 65 are in a conductive state. To do.

また、第１可動接触部２６が第１固定接触部６４ａと接触する位置と、第２可動接触部２４が第２固定接触部６５ａと接触する位置とは、嵌合方向に関して前後となるように、すなわち、嵌合方向に並んでいる。そのため、第１コネクタ１１と第２コネクタ５１との嵌合状態にがたつきが発生したり、第１コネクタ１１又は第２コネクタ５１がこじられたりして、相手側コネクタ収容凹部５４に対して第１ハウジング１２が斜めになっても、第１可動接触部２６と第１固定接触部６４ａとの接触及び第２可動接触部２４と第２固定接触部６５ａとの接触が確実に維持され、第１コネクタ１１と第２コネクタ５１との嵌合検知を確実に行うことができる。 Further, the position where the first movable contact portion 26 contacts the first fixed contact portion 64a and the position where the second movable contact portion 24 contacts the second fixed contact portion 65a are front and rear with respect to the fitting direction. That is, they are arranged in the fitting direction. Therefore, rattling occurs between the first connector 11 and the second connector 51, or the first connector 11 or the second connector 51 is twisted, so that the mating connector receiving recess 54 is Even when the first housing 12 is inclined, the contact between the first movable contact portion 26 and the first fixed contact portion 64a and the contact between the second movable contact portion 24 and the second fixed contact portion 65a are reliably maintained, The fitting detection between the first connector 11 and the second connector 51 can be reliably performed.

さらに、ロック部材２１は、金属製なので、嵌合検知コネクタ１０が高温環境下で使用されても、熱によって変形することがなく、第１コネクタ１１と第２コネクタ５１とが嵌合された状態で、長期間に亘り安定的にロックを維持することができる。例えば、第１ハウジング１２や第２ハウジング５２のような合成樹脂等の絶縁性材料によって形成されたロック部材を使用した場合、嵌合検知コネクタ１０が、例えば、自動車内のような１００〔℃〕程度の高温環境下で長期間に亘り使用されると、熱によるクリープが発生して塑性変形してしまうので、ロックが解除されてしまう可能性がある。これに対し、ロック部材２１は、金属製なので、熱によるクリープが発生することがなく、長期間に亘り安定的にロックを維持することができる。 Furthermore, since the lock member 21 is made of metal, even when the fitting detection connector 10 is used in a high temperature environment, the first connector 11 and the second connector 51 are fitted without being deformed by heat. Thus, the lock can be stably maintained over a long period of time. For example, when a lock member formed of an insulating material such as a synthetic resin such as the first housing 12 or the second housing 52 is used, the fitting detection connector 10 is, for example, 100 [° C.] as in an automobile. If it is used for a long period of time in a high temperature environment, creep due to heat occurs and plastic deformation occurs, so that the lock may be released. On the other hand, since the lock member 21 is made of metal, no creep due to heat occurs, and the lock can be stably maintained over a long period of time.

なお、前記第１コネクタ１１と第２コネクタ５１との嵌合を解除させる場合、まず、オペレータは、手指等によってロック部材２１の操作部２５を押下げる。これにより、本体部２２の可動部２２ａ、傾斜部２２ｄ及び上段部２２ｃが下方に変位し、係合突起６２と係合孔２３との係合が解除され、第１コネクタ１１と第２コネクタ５１とのロックが解除される。この場合、前記可動部２２ａ、傾斜部２２ｄ及び上段部２２ｃは、第１可動接触部２６とは独立に上下方向に弾性的に変位可能となっているので、比較的小さな力を受けても、下方に弾性的に変位する。したがって、オペレータは、比較的小さな力によって操作部２５を押下げ、ロックを解除することができる。そして、第１コネクタ１１を第２コネクタ５１から引離す方向に移動させ、第１コネクタ１１の第１ハウジング１２を第２コネクタ５１の相手側コネクタ収容凹部５４から抜出すことによって、第１コネクタ１１を第２コネクタ５１から離脱させることができる。 When releasing the fitting between the first connector 11 and the second connector 51, first, the operator pushes down the operation portion 25 of the lock member 21 with fingers or the like. As a result, the movable portion 22a, the inclined portion 22d and the upper step portion 22c of the main body portion 22 are displaced downward, the engagement between the engagement protrusion 62 and the engagement hole 23 is released, and the first connector 11 and the second connector 51. Is unlocked. In this case, the movable portion 22a, the inclined portion 22d, and the upper step portion 22c can be elastically displaced in the vertical direction independently of the first movable contact portion 26, so even if a relatively small force is received, It is elastically displaced downward. Therefore, the operator can push down the operation unit 25 with a relatively small force to release the lock. Then, the first connector 11 is moved away from the second connector 51 and the first housing 12 of the first connector 11 is removed from the mating connector housing recess 54 of the second connector 51, thereby causing the first connector 11 to move away. Can be detached from the second connector 51.

このように、本実施の形態においては、第１コネクタ１１のロック部材２１は金属板から成り、弾性的に変位可能な本体部２２を備え、第１可動接触部２６は本体部２２に形成されたスリットによって画定され、第２可動接触部２４は本体部２２に配設され、第１コネクタ１１と第２コネクタ５１とが嵌合すると、第１コネクタ１１のロック部材２１と第２コネクタ５１の係合突起６２とが係合するとともに、第１可動接触部２６及び第２可動接触部２４が第２コネクタ５１の第１固定接触部６４ａ及び第２固定接触部６５ａと接触して、第１嵌合検知端子６４と第２嵌合検知端子６５とが本体部２２を介して導通するようになっている。これにより、ロック部材２１の本体を撓ませるための荷重を低減して操作性を向上させることができ、第１コネクタ１１と第２コネクタ５１との嵌合を安定的に検知することができる。 As described above, in the present embodiment, the lock member 21 of the first connector 11 is made of a metal plate and includes the main body portion 22 that is elastically displaceable, and the first movable contact portion 26 is formed on the main body portion 22. The second movable contact portion 24 is disposed on the main body portion 22, and when the first connector 11 and the second connector 51 are fitted, the lock member 21 of the first connector 11 and the second connector 51 are While the engagement protrusion 62 is engaged, the first movable contact portion 26 and the second movable contact portion 24 come into contact with the first fixed contact portion 64a and the second fixed contact portion 65a of the second connector 51, and the first The fitting detection terminal 64 and the second fitting detection terminal 65 are electrically connected via the main body 22. Thereby, the load for bending the main body of the lock member 21 can be reduced and the operability can be improved, and the fitting between the first connector 11 and the second connector 51 can be detected stably.

そして、第１可動接触部２６は、本体部２２と独立して弾性的に変位可能である。これにより、第１可動接触部２６は、本体部２２の変位に影響されることがなく、安定的に第１固定接触部６４ａとの接触状態を維持することができる。 The first movable contact portion 26 can be elastically displaced independently of the main body portion 22. Thereby, the 1st movable contact part 26 is not influenced by the displacement of the main-body part 22, and can maintain a contact state with the 1st fixed contact part 64a stably.

また、本体部２２は、第１ハウジング１２に固定される固定部２２ｅ、固定部２２ｅに対して変位可能な平板状の可動部２２ａ、及び、固定部２２ｅと可動部２２ａとを折返すように接続する湾曲部２２ｂを備え、第１可動接触部２６を画定するスリットは、可動部２２ａ及び少なくとも湾曲部２２ｂの一部に形成される。これにより、第１可動接触部２６は、本体部２２とは独立に上下方向に弾性的に変位可能となり、一方、本体部２２における可動部２２ａ、傾斜部２２ｄ及び上段部２２ｃも、第１可動接触部２６とは独立に上下方向に弾性的に変位可能となる。 Further, the main body 22 is configured so that the fixed portion 22e fixed to the first housing 12, the flat plate-like movable portion 22a that can be displaced with respect to the fixed portion 22e, and the fixed portion 22e and the movable portion 22a are folded back. A slit that includes the curved portion 22b to be connected and defines the first movable contact portion 26 is formed in the movable portion 22a and at least a part of the curved portion 22b. As a result, the first movable contact portion 26 can be elastically displaced in the vertical direction independently of the main body portion 22, while the movable portion 22a, the inclined portion 22d, and the upper step portion 22c in the main body portion 22 are also first movable. Independent of the contact portion 26, it can be elastically displaced in the vertical direction.

さらに、第１コネクタ１１を第２コネクタ５１に対して移動させると、第１可動接触部２６は第１固定接触部６４ａを擦りながら移動する。これにより、ワイピング効果が生じ、電気的接触抵抗を低減することができるので、第１可動接触部２６及び第１固定接触部６４ａには、例えば、錫めっき等の金めっきよりコストの低いめっきを施すだけで、十分に低い電気的接触抵抗を得ることができる。 Further, when the first connector 11 is moved with respect to the second connector 51, the first movable contact portion 26 moves while rubbing the first fixed contact portion 64a. As a result, a wiping effect can be produced and electrical contact resistance can be reduced. Therefore, the first movable contact portion 26 and the first fixed contact portion 64a can be plated at a lower cost than gold plating such as tin plating. It is possible to obtain a sufficiently low electrical contact resistance only by application.

さらに、第１可動接触部２６及び第２可動接触部２４は、嵌合方向に並んで本体部２２に配設されている。これにより、第１可動接触部２６が第１固定接触部６４ａと接触する位置と、第２可動接触部２４が第２固定接触部６５ａと接触する位置とは、嵌合方向に並んで配設される。そのため、相手側コネクタ収容凹部５４に対して第１ハウジング１２が斜めになっても、第１可動接触部２６と第１固定接触部６４ａとの接触及び第２可動接触部２４と第２固定接触部６５ａとの接触が確実に維持され、第１コネクタ１１と第２コネクタ５１との嵌合検知を確実に行うことができる。 Furthermore, the 1st movable contact part 26 and the 2nd movable contact part 24 are arrange | positioned by the main-body part 22 along with the fitting direction. Thereby, the position where the first movable contact portion 26 contacts the first fixed contact portion 64a and the position where the second movable contact portion 24 contacts the second fixed contact portion 65a are arranged side by side in the fitting direction. Is done. Therefore, even if the first housing 12 is inclined with respect to the mating connector housing recess 54, the contact between the first movable contact portion 26 and the first fixed contact portion 64a and the second movable contact portion 24 and the second fixed contact. The contact with the portion 65a is reliably maintained, and the fitting detection between the first connector 11 and the second connector 51 can be reliably performed.
