図1及び図2に示すように、バックシール11は、所謂ゴム栓であって、電線3の絶縁体外面と、ハウジング本体51の端子挿入口513とに密着するような形状に形成される。尚、バックシール11は、バックリテーナ12によって端子挿入口513からの脱落が防止されるものとする。バックリテーナ12は、バックシール11と共に予め電線3に組み付けられ、コネクタハウジング5への端子金具4の収容が完了した後には、ハウジング本体51のリテーナ係合部512に係合するように形成される。バックリテーナ12には、リテーナ係合部512の上記図示しない一対の係合爪部に対し係合する部分(符号省略)が形成される。 As shown in FIGS. 1 and 2, the back seal 11 is a so-called rubber plug, and is formed in such a shape as to closely contact the insulator outer surface of the electric wire 3 and the terminal insertion opening 513 of the housing body 51 . The back seal 11 is prevented from coming off from the terminal insertion opening 513 by the back retainer 12 . The back retainer 12 is assembled to the electric wire 3 together with the back seal 11 in advance, and is formed so as to be engaged with the retainer engaging portion 512 of the housing body 51 after the terminal fitting 4 is completely accommodated in the connector housing 5 . . The back retainer 12 is formed with portions (reference numerals omitted) that engage with the pair of engaging claws (not shown) of the retainer engaging portion 512 .

次に、上記構成及び構造において、コネクタ2の組み立てについて以下に説明をする。コネクタ2の組み立ては、先ず、電線3にバックシール11及びバックリテーナ12(図1参照)を予め組み付けておき、この後に電線3の端末に端子金具4を接続する端末処理工程を行う。次に、蓋部材8をハウジング本体51の上方に配置した後に、蓋部材8に設けた第一回転軸91をハウジング本体51に設けた第一軸受部92に組み付ける蓋部材組み付け工程を行う。蓋部材組付け工程において、第一回転軸91を、第一軸受部92の前方側に設けた開口94から第一軸受部92内に挿入する。上述したように開口94の幅は第一回転軸91の直径よりも小さい。このため、第一回転軸91は、開口94を押し広げながら第一軸受部92内に挿入される。第一回転軸91が第一軸受部92内に完全に挿入されると、開口94の幅が元の広さに復元するため、開口94から第一回転軸91が簡単に抜け落ちないようになっている。 Next, assembly of the connector 2 in the above configuration and structure will be described below. In assembling the connector 2, first, the back seal 11 and the back retainer 12 (see FIG. 1) are attached to the electric wire 3 in advance, and then the terminal fitting 4 is connected to the end of the electric wire 3, which is a terminal processing step. Next, after disposing the lid member 8 above the housing body 51 , a lid member assembling step is performed in which the first rotating shaft 91 provided on the lid member 8 is attached to the first bearing portion 92 provided on the housing body 51 . In the lid member assembling step, the first rotating shaft 91 is inserted into the first bearing portion 92 through an opening 94 provided on the front side of the first bearing portion 92 . The width of the opening 94 is smaller than the diameter of the first rotating shaft 91 as described above. Therefore, the first rotating shaft 91 is inserted into the first bearing portion 92 while expanding the opening 94 . When the first rotating shaft 91 is completely inserted into the first bearing portion 92 , the width of the opening 94 is restored to its original width, so that the first rotating shaft 91 does not easily fall out of the opening 94 . ing.

次に、上記端末処理工程で電線3が接続された端子金具4を電気接触部41の側からコネクタハウジング5に差し込むような、端子挿入・収容工程を行う。端子金具4は、ハウジング本体51の他端に設けた端子挿入口513からハウジング本体51内に挿入される。端子金具4の電気接触部41は、ハウジング本体51の中間、連結部511を通ってボルト締結筒部52内に収容される。ボルト締結筒部52内に収容された電気接触部41は、電気接触部41の先端に形成された三つのハウジング係合部412がボルト締結筒部52の内面に形成された三つの端子突き当て部528に当接して保持される。最後に、バックシール11及びバックリテーナ12をスライドさせて、バックシール11を端子挿入口513に組み付けるとともに、バックリテーナ12をハウジング本体51のリテーナ係合部512に係合させるような、リテーナ組み付け工程を行うと、コネクタ2の組み付けが完了する。 Next, a terminal insertion/accommodation step is performed in which the terminal fitting 4 to which the electric wire 3 is connected in the terminal processing step is inserted into the connector housing 5 from the electrical contact portion 41 side. The terminal fitting 4 is inserted into the housing body 51 through a terminal insertion opening 513 provided at the other end of the housing body 51 . The electrical contact portion 41 of the terminal fitting 4 is accommodated in the bolt fastening cylinder portion 52 through the intermediate portion of the housing body 51 , the connecting portion 511 . The electrical contact portion 41 accommodated in the bolt fastening cylinder portion 52 has three terminal abutting portions formed on the inner surface of the bolt fastening cylinder portion 52 and three housing engaging portions 412 formed at the tip of the electrical contact portion 41 . It is held against the portion 528 . Finally, a retainer assembling process in which the back seal 11 and the back retainer 12 are slid to assemble the back seal 11 into the terminal insertion opening 513 and the back retainer 12 is engaged with the retainer engaging portion 512 of the housing body 51. , the assembly of the connector 2 is completed.

次に、コネクタ2と相手機器との接続について説明する。まず、図5に示すように、第一回転軸91を中心に蓋部材8を開方向に回転させ、蓋部材8を開位置に位置づける。このとき、仮係止部95が仮係止部96よりも後側に位置するため、蓋部材8が開位置で仮係止される。即ち、蓋部材8に閉方向の力が多少加わったとしても、仮係止部95が仮係止部96を乗り越えることができず、蓋部材8が開位置に保持される。次に、第二開口部522を相手機器側に向けて、連結部511より下側のコネクタハウジング5を相手機器のハウジングに嵌合させる。 Next, the connection between the connector 2 and the mating device will be described. First, as shown in FIG. 5, the lid member 8 is rotated about the first rotating shaft 91 in the opening direction to position the lid member 8 at the open position. At this time, since the temporary locking portion 95 is located on the rear side of the temporary locking portion 96, the lid member 8 is temporarily locked at the open position. That is, even if some force is applied to the lid member 8 in the closing direction, the temporary locking portion 95 cannot get over the temporary locking portion 96, and the lid member 8 is held at the open position. Next, with the second opening 522 facing toward the mating device, the connector housing 5 below the connecting portion 511 is fitted to the housing of the mating device.

なお、相手機器のハウジングの内側面には、キー514がスライド挿入可能な溝部が設けられている。このため、キー514の位置が違うタイプの異なるコネクタハウジング5を嵌合することができないため、誤組付け防止を図ることができる。例えば、本実施形態では、図3に示すように、右側面のキー514は左側面のキー514よりも前側に設けているタイプのコネクタハウジング5である。これに対して、右側面のキー514は左側面のキー514よりも後側に設けている別のタイプのコネクタハウジング5を相手機器のハウジングに嵌合することができない。 A groove into which the key 514 can be slidably inserted is provided on the inner surface of the housing of the mating device. For this reason, different types of connector housings 5 having different positions of the keys 514 cannot be fitted, so that erroneous assembly can be prevented. For example, in this embodiment, as shown in FIG. 3, the connector housing 5 is of a type in which the key 514 on the right side is provided in front of the key 514 on the left side. On the other hand, the key 514 on the right side cannot fit the connector housing 5 of another type provided behind the key 514 on the left side to the housing of the mating device.

このとき、第二開口部522から相手端子が挿入され、電気接触部41の下側に重ねられる。蓋部材8を開けた状態で、第一開口部521からボルトを挿入して、電気接触部41と相手端子とをボルト締結する。その後、第一回転軸91を中心に蓋部材8を閉方向に回転させる。蓋部材8に閉方向に大きな力が加わると、仮係止部95が、仮係止部96を乗り越えて、仮係止部96よりも前側に位置すると、蓋部材8が閉方向に回転可能となる。その後、第二回転軸101を第二軸受部102の上側に向いた開口104から挿入する。このとき、第二回転軸101は開口104を押し広げながら第二軸受部102内に挿入される。第二回転軸101が第二軸受部102内に完全に挿入されると、開口104の幅が元の広さに復元する。これにより、蓋部材8に開方向の力が多少加わっても、開口104から第二回転軸101が出て、蓋部材8が開いてしまう恐れがない。 At this time, the mating terminal is inserted through the second opening 522 and overlapped on the lower side of the electrical contact portion 41 . With the lid member 8 opened, a bolt is inserted through the first opening 521 to fasten the electrical contact portion 41 and the mating terminal with the bolt. After that, the lid member 8 is rotated in the closing direction around the first rotating shaft 91 . When a large force is applied to the lid member 8 in the closing direction, the temporary locking portion 95 climbs over the temporary locking portion 96, and when the temporary locking portion 96 is positioned in front of the temporary locking portion 96, the lid member 8 can rotate in the closing direction. becomes. After that, the second rotating shaft 101 is inserted through the upward opening 104 of the second bearing portion 102 . At this time, the second rotating shaft 101 is inserted into the second bearing portion 102 while expanding the opening 104 . When the second rotary shaft 101 is completely inserted into the second bearing portion 102, the width of the opening 104 is restored to its original width. As a result, even if some force is applied to the lid member 8 in the opening direction, there is no danger that the second rotating shaft 101 will protrude from the opening 104 and the lid member 8 will open.

電気接触部41と相手端子との接続部をメンテナンスしたい場合は、第一回転軸91を中心に蓋部材8を開方向に回転させて第一開口部521を露出させる。このとき、作業者は、一対の操作部105を持って、上側に持ち上げると、開口104から第二回転軸101が第二軸受部102外に出て、蓋部材8が閉方向に回転可能となる。その後、作業者は、蓋部材8をさらに開方向に回転させて、図5に示すように、蓋部材8を開方向に位置づける。 When it is desired to perform maintenance on the connecting portion between the electrical contact portion 41 and the mating terminal, the cover member 8 is rotated about the first rotating shaft 91 in the opening direction to expose the first opening portion 521 . At this time, when the operator holds the pair of operation portions 105 and lifts them upward, the second rotating shaft 101 comes out of the second bearing portion 102 through the opening 104, and the lid member 8 can rotate in the closing direction. Become. After that, the operator further rotates the lid member 8 in the opening direction to position the lid member 8 in the opening direction as shown in FIG.

これにより、第一開口部521から電気接触部41を臨むことができ、ボルトの取り外しなどのメンテナンス作業を行うことができる。メンテナンス作業が終わると、作業者は、蓋部材8を図2に示す閉位置に位置づけ、第一開口部521を塞いで、端子金具4の防水を図ることができる。 As a result, the electrical contact portion 41 can be viewed from the first opening 521, and maintenance work such as bolt removal can be performed. After the maintenance work is completed, the operator can position the cover member 8 at the closed position shown in FIG.

上述した実施形態によれば、コネクタ2は、蓋部材8を開閉させる第一開閉機構9と、第二開閉機構10と、を備えている。第二開閉機構10の第二軸受部102には、上側に第二回転軸101を第二軸受部102内外に着脱するための開口104が設けられている。これにより、蓋部材8の前側を上側に向けて押すと、開口104から第二回転軸101が第二軸受部102外に出て、蓋部材8が第一開閉機構9の第一回転軸91を中心に開方向に回転でき、工具を使う必要がなく、作業性の向上を図ることができる。しかも、第一開閉機構9が破損した場合であっても、第二開閉機構10の第二回転軸101を中心に蓋部材8を回転させて、蓋部材8を開閉することができる。 According to the embodiment described above, the connector 2 includes the first opening/closing mechanism 9 and the second opening/closing mechanism 10 for opening and closing the lid member 8 . The second bearing portion 102 of the second opening/closing mechanism 10 is provided with an opening 104 for attaching and detaching the second rotating shaft 101 to the inside and outside of the second bearing portion 102 on the upper side. As a result, when the front side of the lid member 8 is pushed upward, the second rotating shaft 101 comes out of the second bearing portion 102 through the opening 104, and the lid member 8 moves toward the first rotating shaft 91 of the first opening/closing mechanism 9. can be rotated in the opening direction, and there is no need to use a tool, and workability can be improved. Moreover, even if the first opening/closing mechanism 9 is damaged, the lid member 8 can be rotated around the second rotating shaft 101 of the second opening/closing mechanism 10 to open and close the lid member 8 .

上述した実施形態によれば、第二開閉機構10は、蓋部材8に設けられ、第二回転軸101の中心軸方向(左右方向)に突出する操作部105を有している。これにより、操作部105を上側に押して、容易に開口104から第二回転軸101を第二軸受部102外に出すことができ、作業性の向上を図ることができる。 According to the above-described embodiment, the second opening/closing mechanism 10 has the operating portion 105 provided on the lid member 8 and protruding in the central axis direction (horizontal direction) of the second rotating shaft 101 . As a result, the operating portion 105 can be pushed upward to easily move the second rotating shaft 101 out of the second bearing portion 102 through the opening 104, thereby improving workability.

上述した実施形態によれば、コネクタハウジング5には、連結部511の左右方向両側面にそれぞれキー514が設けられ、左右方向両側面にそれぞれ設けられたキー514は、前後方向の位置が互いに異なる。これにより、コネクタハウジング5を相手機器のハウジングに誤組付けするのを防止できる。 According to the above-described embodiment, the connector housing 5 is provided with the keys 514 on both left and right side surfaces of the connecting portion 511, and the keys 514 provided on both left and right side surfaces are positioned at different positions in the front-rear direction. . As a result, it is possible to prevent the connector housing 5 from being erroneously assembled to the housing of the mating device.

上述した実施形態によれば、ボルト締結筒部52は、ハウジング本体51よりも第二開口部522側の外側面に設けられたOリング7を収容するリング装着部524と、リング装着部524の第一開口部521側の縁部(上側のフランジ部526)よりも外側に突出するフランジ部527と、を有する。これにより、上側から見てOリング7が露出しないようにすることにより、より一層、相手機器への防水を図ることができる。 According to the above-described embodiment, the bolt fastening cylinder portion 52 includes the ring mounting portion 524 that accommodates the O-ring 7 provided on the outer surface closer to the second opening portion 522 than the housing body 51, and the ring mounting portion 524. and a flange portion 527 that protrudes outward from the edge portion (upper flange portion 526) on the first opening portion 521 side. As a result, by preventing the O-ring 7 from being exposed when viewed from above, it is possible to further waterproof the mating device.

上述した実施形態によれば、第一開閉機構9は、蓋部材8を開位置で仮係止する仮係止部95、96を有する。これにより、蓋部材8の開位置が保持され、より一層、作業性の向上を図ることができる。 According to the above-described embodiment, the first opening/closing mechanism 9 has the temporary locking portions 95 and 96 that temporarily lock the lid member 8 at the open position. As a result, the open position of the lid member 8 is maintained, and workability can be further improved.
