The inner cylindrical portion 21 extends from the surface of the flange portion 26 provided in the connector main body 2, and a groove 22 in which the O-ring 4 is mounted is provided on the outer peripheral surface.

方向規制部２３は、フランジ部２６の外周面から側方に延びた板状体の表面に形成されている。方向規制部２３は、内円筒部２１と対向する面に溝部２４を備え、表面にはボッチ部２５を備えている。   The direction restricting portion 23 is formed on the surface of a plate-like body that extends laterally from the outer peripheral surface of the flange portion 26. The direction restricting portion 23 includes a groove portion 24 on a surface facing the inner cylindrical portion 21, and includes a boch portion 25 on the surface.

コネクタカバー３は、図２に示すように、コネクタ本体２の内円筒部２１に装着される外円筒部３１の外周面に、保持部３２を備えている。保持部３２は、板状の突起部３３及び被され部３４を外円筒部３１の軸心方向に並べて備えている。   As shown in FIG. 2, the connector cover 3 includes a holding portion 32 on the outer peripheral surface of the outer cylindrical portion 31 attached to the inner cylindrical portion 21 of the connector main body 2. The holding part 32 includes a plate-like protrusion 33 and a covered part 34 arranged in the axial direction of the outer cylindrical part 31.

被され部３４は、突起部３３よりもコネクタカバー３の天板側に位置しており、突起部３３よりも長い板状を呈している。被され部３４の突起部３３と対向する位置には、穴３５が形成されている。穴３５は、突起部３３よりも大きく形成されている。   The covered portion 34 is located on the top plate side of the connector cover 3 with respect to the protruding portion 33 and has a plate shape longer than the protruding portion 33. A hole 35 is formed at a position facing the protruding portion 33 of the covered portion 34. The hole 35 is formed larger than the protrusion 33.

コネクタカバー３は、図３に示すように、コネクタ本体２が備える内円筒部２１に被せられて装着される。コネクタカバー３は、図４（ａ）に示すように内円筒部２１に外円筒部３１が外環されて被せられると、図４（ｂ）に示すように保持部３２が方向規制部２３に保持されるまで、外円筒部３１の周方向に回転させられる。   As shown in FIG. 3, the connector cover 3 is attached so as to cover an inner cylindrical portion 21 provided in the connector main body 2. As shown in FIG. 4A, when the outer cylindrical portion 31 is covered with the outer cylindrical portion 31 as shown in FIG. 4A, the connector cover 3 has the holding portion 32 attached to the direction regulating portion 23 as shown in FIG. The outer cylindrical portion 31 is rotated in the circumferential direction until it is held.

Ｏリング４は、図５に示すように、内円筒部２１の外周面と外円筒部３１の内周面との間に配置されて、内円筒部２１と外円筒部３１との間をシールしている。また、保持部３２は、溝部２４に収容された突起部３３と方向規制部２３の表面を覆った被され部３４とで方向規制部２３を挟み込んで、方向規制部２３に保持される。方向規制部２３のボッチ部２５は、図６に示すように被され部３４の穴３５内に収容される。   As shown in FIG. 5, the O-ring 4 is disposed between the outer peripheral surface of the inner cylindrical portion 21 and the inner peripheral surface of the outer cylindrical portion 31, and seals between the inner cylindrical portion 21 and the outer cylindrical portion 31. doing. Further, the holding portion 32 is held by the direction restriction portion 23 with the direction restriction portion 23 sandwiched between the projection portion 33 accommodated in the groove portion 24 and the covered portion 34 covering the surface of the direction restriction portion 23. As shown in FIG. 6, the bottom portion 25 of the direction restricting portion 23 is received in the hole 35 of the covered portion 34.

方向規制部２３に保持された保持部３２は、方向規制部２３のボッチ部２５に被され部３４が係止されることで、外円筒部３１の周方向への移動が規制され、また、突起部３３と被され部３４とで方向規制部２３を挟み込むことで、外円筒部３１の軸心方向への移動が規制される。   The holding part 32 held by the direction restricting part 23 is covered with the bottom part 25 of the direction restricting part 23 and the part 34 is locked, so that the movement of the outer cylindrical part 31 in the circumferential direction is restricted. By sandwiching the direction restricting portion 23 between the protruding portion 33 and the covered portion 34, the movement of the outer cylindrical portion 31 in the axial direction is restricted.

本実施形態によれば、コネクタカバー３の周方向への移動をボッチ部２５で規制してコネクタカバー３の回転を防止し、突起部３３と被され部３４とで方向規制部２３を挟み込んでコネクタカバー３の軸心方向への移動を防止できる。このため、コネクタ本体２に対するコネクタカバー３の保持力を向上させられる。   According to the present embodiment, the movement of the connector cover 3 in the circumferential direction is restricted by the boss portion 25 to prevent the connector cover 3 from rotating, and the direction restricting portion 23 is sandwiched between the protruding portion 33 and the covered portion 34. The movement of the connector cover 3 in the axial direction can be prevented. For this reason, the holding force of the connector cover 3 with respect to the connector main body 2 can be improved.

また、本実施形態によれば、内円筒部２１の開口端側を向いた方向規制部２３の表面が平坦に形成され、被され部３４がこの平坦面の全面を覆うように方向規制部２３に被されることで、方向規制部２３の周縁よりも遠い位置まで被され部３４の先端を延ばすことができる。コネクタ１の多極化に伴いコネクタ間口が広大化すると、コネクタカバー３を保持部と反対側からコネクタ本体２から外すような力が働いた際に突起部３３が溝部２４から抜け出し、コネクタカバー３が外れ易くなる。しかし、コネクタ１によれば、このような力が働いた際に、突起部３３が溝部２４から抜け出すのを防止するのに十分な長さの被され部３４を設けられる。   Further, according to the present embodiment, the surface of the direction restricting portion 23 facing the opening end side of the inner cylindrical portion 21 is formed flat, and the direction restricting portion 23 is so covered that the covered portion 34 covers the entire flat surface. By being covered, the tip of the portion 34 can be extended to a position farther from the periphery of the direction restricting portion 23. When the connector opening becomes wide as the connector 1 becomes multipolar, the projection 33 comes out of the groove 24 when a force is applied to remove the connector cover 3 from the connector body 2 from the side opposite to the holding portion, and the connector cover 3 is detached. It becomes easy. However, according to the connector 1, the covered portion 34 having a length sufficient to prevent the protruding portion 33 from coming out of the groove portion 24 when such force is applied is provided.

また、本実施形態によれば、被され部３４の穴３５から方向規制部２３のボッチ部２５を目視することで、コネクタカバー３がコネクタ本体２の正規位置に装着されているかを確認できる。また、被され部３４と突起部３３とに重なり合う部分が形成されないことから、コネクタカバー３の製造用の金型に可動部を設ける必要がなく、金型構造を簡略化できる。   Further, according to the present embodiment, it is possible to confirm whether or not the connector cover 3 is attached to the normal position of the connector main body 2 by visually observing the bottom portion 25 of the direction restricting portion 23 from the hole 35 of the covered portion 34. Moreover, since the overlapping part is not formed in the covered part 34 and the protrusion part 33, it is not necessary to provide a movable part in the metal mold | die for manufacturing the connector cover 3, and a metal mold | die structure can be simplified.

なお、上記実施形態では、コネクタ本体２の溝２２にＯリング４が装着されている場合について説明したが、コネクタカバー３の外円筒部３１に装着されていてもよい。また、突起部３３及び被され部３４は、外円筒部３１の外周面に直接形成されていてもよい。   In the above embodiment, the case where the O-ring 4 is mounted in the groove 22 of the connector main body 2 has been described. However, the O-ring 4 may be mounted on the outer cylindrical portion 31 of the connector cover 3. Further, the protruding portion 33 and the covered portion 34 may be directly formed on the outer peripheral surface of the outer cylindrical portion 31.

また、ボッチ部２５は、コネクタカバー３に係止されてコネクタカバー３の周方向への回転を規制できればよく、突起部３３等に係止されるよう構成されていてもよい。また、方向規制部２３は、フランジ部２６の外周面から側方に延びた板状体の表面から内円筒部２１側に向けてＬ字状に延びた板状体から形成されていてもよい。   Further, the bottom portion 25 only needs to be locked to the connector cover 3 to restrict the rotation of the connector cover 3 in the circumferential direction, and may be configured to be locked to the protruding portion 33 or the like. Further, the direction restricting portion 23 may be formed of a plate-like body extending in an L shape from the surface of the plate-like body extending laterally from the outer peripheral surface of the flange portion 26 toward the inner cylindrical portion 21 side. .

また、上記実施形態では、被され部３４が備える穴３５の側面にボッチ部２５が係止される場合について説明したが、被され部３４には凹部等のボッチ部２５が係止される箇所が設けられていればよい。   Moreover, although the said embodiment demonstrated the case where the bottom part 25 was latched by the side surface of the hole 35 with which the covered part 34 was provided, the location where the bottom part 25, such as a recessed part, is latched by the covered part 34 Should just be provided.

また、被され部３４の長さは、コネクタカバー３を保持部３２と反対側からコネクタ本体２から外すような力が働いた際に、突起部３３が溝部２４から抜け出すのを防止できるよう、内円筒部２１の間口等に応じて定めることができる。   The length of the covered portion 34 is such that the protrusion 33 can be prevented from coming out of the groove portion 24 when a force is applied to remove the connector cover 3 from the connector body 2 from the side opposite to the holding portion 32. It can be determined according to the opening of the inner cylindrical portion 21 or the like.
