An engaging end h 1 is formed which engages the piece k ′.
【０００４】 第２ハウジングｃには内壁ｋに溝ｋ1 が形成され、後述する保持具ｍの突起ｍ 1 ′との係止手段を構成している。 第１ハウジングｂにはシュラウドｂ1 が形成されて、キャビテイｂ2 を形成す るとともに、両第１ハウジングｂ，第２ハウジングｃが嵌合した際に、キャビテ イｃ1 に受入れられて、ガスケットｎに当接しシール手段を構成している。In the second housing c, the groove k is formed on the inner wall k.1Is formed, and a protrusion m of a holder m described later is formed. 1 'Constitutes locking means. Shroud b on first housing b1Is formed, cavities b2And when the first housing b and the second housing c are fitted together, the cavity c1Is received by the gasket n and comes into contact with the gasket n to form a sealing means.
【０００５】 キャビテイｂ2 にはシュラウドｂ1 の内面に接して移動可能な保持具ｍが収容 され、該保持具ｍは保持プレートｍ1 と第１ガイドｍ2 が形成されるとともに、 保持プレートｍ1 には前記雄端子ｆの接触片ｆ1 の挿通手段を構成する挿通孔ｍ 3 が形成されている（図６（Ａ）参照）。Cavity b2Shroud b1A holder m that is movable in contact with the inner surface of the holder is housed, and the holder m is a holding plate m.1And the first guide m2And the holding plate m1Is the contact piece f of the male terminal f.1Insertion hole m that constitutes the insertion means of 3 Are formed (see FIG. 6A).
【０００６】 第１ガイドｍ2 はシュラウドｂ1 と可撓係止片ｉ又は壁ｑとの間のキャビテイ ｂ2 内を移動するように構成されている。壁ｑには溝ｑ1 が形成され、該溝ｑ1 は前記第１ガイドｍ2 のラッチングアームである突起ｍ4 の摺動手段を構成し、 第１ガイドｍ2 が嵌合方向前方に移動したとき、つまり、コネクタの接続が解除 されたとき、前記溝ｑ1 の形成されていない端部ｑ2 に係止されるとともに、第 １ハウジングｂから保持具ｍが外れるのを防止するストッパ手段を構成している （図６（Ｃ）参照）。The first guide m 2 is configured to move in the cavity b 2 between the shroud b 1 and the flexible locking piece i or the wall q. Grooves q 1 is formed in the wall q, groove q 1 constitutes a sliding means protruding m 4 is a latching arm of said first guide m 2, moving the first guide m 2 is the fitting direction forward When the connector is disconnected, that is, when the connector q is released, the stopper means is locked to the end portion q 2 where the groove q 1 is not formed and prevents the holder m from coming off from the first housing b. (See FIG. 6C).
【０００７】 保持プレートｍ1 の反対側には、第２ガイドｍ5 が形成されるとともに、ラッ チングアームである係合部ｍ6 が設けられ、該係合部ｍ6 はシュラウドｂ1 の先 端方向内面に形成された凹部ｂ3 の端部と係合して保持具ｍを一定位置に留め、 保持具ｍが一定位置に留まることによって、保持プレートｍ1 が雄端子ｆの接触 片ｆ1 の先端を適切な位置に保持する位置保持手段を構成している（図６（Ｂ） 参照）（特許出願公告平３−５５９５０）。[0007] opposite side of the holding plate m 1, together with the second guide m 5 is formed, it is provided engaging portion m 6 is a rack quenching arm engagement portion m 6 the previous shroud b 1 By engaging the end of the concave portion b 3 formed on the inner surface in the end direction to hold the holder m in a fixed position and the holder m stays in a fixed position, the holding plate m 1 contacts the contact piece f of the male terminal f. A position holding means for holding the tip of 1 at an appropriate position is configured (see FIG. 6B) (Patent Application Publication No. 3-55950).
【０００８】 従来例は上記のように構成されているので、第１ハウジングｂを組み立てるに は、キャビテイｄに防水栓ｅ1 を貫通した電線ｅを接続した雄端子ｆの先端を挿 通孔ｄ1 に挿入して、可撓係止片ｉの先端が雄端子ｆの係合孔ｊの端縁を係止す る。次いで、係止具ｍの第１ガイドｍ2 が可撓係止片ｉ及び壁ｑを挟むようにキ ャビテイｂ2 に挿入して突起ｍ4 を端部ｑ2 と係合させる。この時、係合部ｍ6 は凹部ｂ3 と係合するとともに、雄端子ｆの接触片ｆ1 は保持プレートｍ1 の挿 通孔ｍ3 を挿通して所定の位置に保持される。Since the conventional example is configured as described above, when assembling the first housing b, the tip of the male terminal f to which the electric wire e penetrating the waterproof plug e 1 is connected to the cavity d is inserted into the insertion hole d. 1 and the tip of the flexible locking piece i locks the edge of the engaging hole j of the male terminal f. Then, the first guide m 2 of the locking tool m is inserted into the cavity b 2 so as to sandwich the flexible locking piece i and the wall q, and the projection m 4 is engaged with the end q 2 . At this time, the engaging portion m 6 engages with the concave portion b 3, and the contact piece f 1 of the male terminal f is inserted through the insertion hole m 3 of the holding plate m 1 and held at a predetermined position.
【０００９】 第２ハウジングｃの組み立ては、キャビテイｇに防水栓ｅ1 を貫通した電線ｅ を接続した雌端子ｈを挿入して可撓係止片ｋ′が雌端子ｈの係合端ｈ1 を係止す る。 次に、図７，図８に基づき両ハウジングの嵌合手順を説明する。To assemble the second housing c, the female terminal h to which the electric wire e 1 which penetrates the waterproof plug e 1 is connected is inserted into the cavity g, and the flexible locking piece k ′ is engaged with the engaging end h 1 of the female terminal h. Lock. Next, the fitting procedure of both housings will be described with reference to FIGS.
【００１０】 図７に示すようにシュラウドｂ1 がキャビテイｃ1 に挿入されると、雄端子ｆ の接触片ｆ1 は保持プレートｍ1 の挿通孔ｍ3 により適切な所定の位置に保持さ れていることから、接触片ｆ1 は周囲の壁面に衝突することなく挿通孔ｇ1 に挿 入され雌端子ｈに正確に挿入される。この時係合部ｍ6 がシュラウドｂ1 の凹部 ｂ3 と係合していることから、保持具ｍは第１ハウジングｂ内に向かって直ちに 後退せず、係合部ｍ1 ′が内壁ｋを乗り越えて溝ｋ1 に挿入されるまでその位置 に止まり接触片ｆ1 の挿通孔ｇ1 への挿入を容易にしている。When the shroud b 1 is inserted into the cavity c 1 as shown in FIG. 7, the contact piece f 1 of the male terminal f 1 is held at an appropriate predetermined position by the insertion hole m 3 of the holding plate m 1. Therefore, the contact piece f 1 is inserted into the insertion hole g 1 and is accurately inserted into the female terminal h without colliding with the surrounding wall surface. At this time, since the engaging portion m 6 is engaged with the concave portion b 3 of the shroud b 1 , the holder m does not immediately retract toward the inside of the first housing b, and the engaging portion m 1 ′ has the inner wall k. It stays at that position until it passes over and is inserted into the groove k 1 , facilitating the insertion of the contact piece f 1 into the insertion hole g 1 .
【００１１】 更に両第１ハウジングｂと第２ハウジングｃとの嵌合を進めると、内壁ｋの押 し込む力により係合部ｍ6 が凹部ｂ3 からシュラウドｂ1 に乗り上げて係合が解 けて、保持具ｍは第１ハウジングｂ内に押しこまれ、図８のように嵌合が完了す る。When the fitting between the first housing b and the second housing c is further advanced, the engaging portion m 6 rides up from the recess b 3 to the shroud b 1 by the pushing force of the inner wall k, and the engagement is released. Then, the holder m is pushed into the first housing b, and the fitting is completed as shown in FIG.
【００１２】 従来例は上記の説明のように、一端正しく組み立てられたコネクタの各端子は 、保持具により適切な所定の位置に保持されるので嵌合不良による導通不良を発 生しないが、コネクタハウジングの組み立て時における端子の半挿入状態の検知 は出来ない欠点がある。In the conventional example, as described above, each terminal of the connector which has been assembled correctly once is held at an appropriate predetermined position by the holder, so that a conduction failure due to a fitting failure does not occur. There is a drawback that it is not possible to detect the half-inserted state of the terminal when assembling the housing.
【００１３】[0013]
本考案は、上記した点に鑑み、ワイヤハーネス等の接続に用いられるコネクタ において、端子がコネクタハウジングの端子収容室に不完全に挿入された状態を 検知出来る構造のコネクタを提供することを目的とする。 The present invention has been made in view of the above points, and an object thereof is to provide a connector used for connecting a wire harness or the like, which has a structure capable of detecting a state in which a terminal is imperfectly inserted into a terminal accommodating chamber of a connector housing. To do.
【００１４】[0014]
上記の目的を達成するために、本考案は、端子収容室を有するコネクタハウジ ングと、該端子収容室内に挿入される係合部を有する端子と、該コネクタハウジ ングの後部に対して仮係止状態と本係止状態の２段階をもって組み合わされる端 子係止具とからなるコネクタにおいて、前記コネクタハウジングの端子収容室の 端子接触片の挿通孔の端子挿入がわに隣接して該挿通孔に向かった傾斜面を有す る一対のガイドを連設するとともに、前記端子係止具の端子収容室の底板に、先 端に前記ガイドと対応する一対の突起を有する係合突部を形成した可撓係止片を 連設し、該係合突部が前記端子金具の係合部と係合する構成を採用した。 To achieve the above object, the present invention provides a connector housing having a terminal accommodating chamber, a terminal having an engaging portion to be inserted into the terminal accommodating chamber, and a temporary engagement with respect to a rear portion of the connector housing. In a connector consisting of a terminal locking device that is assembled in two stages of a stopped state and a final locking state, the terminal insertion of the insertion hole of the terminal contact piece of the terminal housing chamber of the connector housing is adjacent to the wa A pair of guides each having an inclined surface facing toward each other, and an engaging protrusion having a pair of protrusions corresponding to the guides formed on the bottom plate of the terminal receiving chamber of the terminal locking device. A flexible locking piece is continuously provided, and the engaging projection engages with the engaging portion of the terminal fitting.
【００１５】[0015]
コネクタハウジングと端子係止具とが仮係止の状態あるとき、端子を前記コネ クタハウジングの端子収容室に挿入し、次いで端子係止具を本係止状態にコネク タハウジングに挿入して端子係止具の端子収容室の底板に連設された可撓係止片 の先端の両サイドの突起が、コネクタハウジングの端子収容室全面の端子接触片 の挿通孔に隣接して形成されたガイドの傾斜面を摺動して前記可撓係止片の先端 端縁が端子の係合部たる孔の端縁を係止する。 When the connector housing and the terminal locking device are in the temporary locking state, insert the terminal into the terminal housing chamber of the connector housing, and then insert the terminal locking device into the final locking state into the connector housing. Guides formed on both sides of the tip of the flexible locking piece connected to the bottom plate of the terminal housing of the locking tool, adjacent to the insertion holes of the terminal contact piece on the entire surface of the terminal housing of the connector housing. By sliding on the inclined surface, the end edge of the flexible locking piece locks the edge of the hole which is the engaging portion of the terminal.
【００１６】 ところが、端子が端子収容室の所定の位置まで完全に挿入されていないと、端 子係止具を本係止状態にコネクタハウジングに一杯挿入しようと押し込んでも、 端子係止具の端子収容室の底板に連設された可撓係止片の先端の真上に端子の係 合部たる孔が位置していない為、可撓係止片の先端は該孔に没入できず、可撓係 止片の先端の両サイドの突起は前記ガイドの傾斜面と端子底板間に挟まれた状態 で突っ張り合い端子係止具は本係止状態に挿入することは不可能である。However, if the terminal is not completely inserted to a predetermined position in the terminal accommodating chamber, even if the terminal locking tool is pushed into the connector housing to the full locking state, the terminal of the terminal locking tool is pushed. Since the hole that is the engaging part of the terminal is not located directly above the tip of the flexible locking piece that is connected to the bottom plate of the storage chamber, the tip of the flexible locking piece cannot be recessed in the hole. The projections on both sides of the tip of the flexible locking piece are butt-tightened in a state of being sandwiched between the inclined surface of the guide and the terminal bottom plate, and the terminal locking device cannot be inserted into the final locking state.
【００１７】 即ち、この端子係止具が本係止状態に移行出来ないことで、端子の半挿入を確 実に検知出来る。That is, since the terminal locking device cannot shift to the fully locked state, the half insertion of the terminal can be reliably detected.
