Further, the tip of the terminal 42 of the connector 9 is housed in a shield frame made of metal or the like. The substrate 41 is formed to be wider on the left and right than the shield 51.

前記コネクタ取付部１８には、車両側の前記コネクタ８が収納される。このコネクタ８のコネクタケース５５は合成樹脂からなり、そのコネクタケース５５の左右側面後部に、前記開口部３１に嵌入する嵌合突部５６を突設し、コネクタ取付部１８に後方からコネクタ８を挿入することにより、開口部３１に嵌合突部５６が嵌合し、前記コネクタ取付部１８内にコネクタ８が着脱可能に固定される。この固定状態で、コネクタ８の先端が、上段の前記コネクタ挿入孔６に臨んで配置され、コネクタ挿入孔６を通してコネクタ８の先端に、外部コネクタたる雄型のＵＳＢコネクタ１０が接続される。 The connector 8 on the vehicle side is housed in the connector mounting portion 18. The connector case 55 of the connector 8 is made of synthetic resin, and a fitting protrusion 56 that fits into the opening 31 is projected from the rear left and right sides of the connector case 55, and the connector 8 is attached to the connector mounting portion 18 from the rear. By inserting, the fitting protrusion 56 is fitted into the opening 31, and the connector 8 is detachably fixed in the connector mounting portion 18. In this fixed state, the tip of the connector 8 is arranged facing the connector insertion hole 6 in the upper stage, and the male USB connector 10 as an external connector is connected to the tip of the connector 8 through the connector insertion hole 6.

このようにコネクタ８をコネクタ取付部１８に収納すると、コネクタケース５５の側面が係止片２１，２１の内面に当接又は近接し、好ましくは当接し、これにより係止片２１が内側に撓むことが防止され、係止片２１と取付孔２の開口縁との確実な係止状態を維持することができる。尚、コネクタケース５５の側面が係止片２１の内面に間隔を持って近接している場合は、その間隔分だけ係止片２１が内側に撓んでも、係止片２１が取付孔２から外れない間隔に設定する。 When the connector 8 is housed in the connector mounting portion 18 in this way, the side surface of the connector case 55 abuts or approaches the inner surface of the locking pieces 21 and 21 and preferably abuts, whereby the locking piece 21 flexes inward. Peeling is prevented, and a secure locking state between the locking piece 21 and the opening edge of the mounting hole 2 can be maintained. When the side surface of the connector case 55 is close to the inner surface of the locking piece 21 with a gap, the locking piece 21 can be inserted from the mounting hole 2 even if the locking piece 21 bends inward by the distance. Set the interval so that it does not come off.

前記コネクタ受け部材５の前面には、前記コネクタ挿入孔６，６を開閉する蓋体６１が設けられている。また、前記コネクタ受け部材５の上部から前側に取付部６２を前向きに突設し、図６に示すように、前記取付部６２の先端側と蓋体６１の上部に取付軸６３を挿通し、この取付軸６３を中心に蓋体６１を開閉自在に設けている。また、取付軸６３には付勢手段であるトーションスプリング６４が外装され、そのトーションスプリング６４により蓋体６１を閉める方向に付勢している。 A lid 61 for opening and closing the connector insertion holes 6 and 6 is provided on the front surface of the connector receiving member 5.

Further, a torsion spring 64, which is an urging means, is externally attached to the mounting shaft 63, and the torsion spring 64 urges the attachment shaft 61 in a direction of closing the lid 61.

次に、前記コネクタハウジング３の取付方法について説明する。車両の内装材１に前記取付孔２を形成する。この場合、図１１に示すように、製造時に形成されていた孔６６を加工して取付孔２を拡大して形成することができる。内装材１の前側からコネクタハウジング３の本体４を取付孔２に挿入する。図８に示すように本体４を取付孔２に挿入すると、取付孔２に係止片２１の傾斜案内面２４が当接し、係止片２１が内側に押し込まれるように弾性変形し、傾斜案内面２４が取付孔２を通過することにより、係止片２１が復帰し、内装材１の外面にコネクタ受け部材５の係止縁部７の後面が当接すると共に、取付孔２の開口縁に係止片２１の先端外面２６が近接又は当接する。この状態で、コネクタハウジング３を前側に動かそうとする力が加わっても、取付孔２の後側角部２Ｋは斜め係止面部２５Ｂに当接するため、位置ずれを防止できる。尚、図９及び図１１では、コネクタ８のハーネス５７を図示しているが、他の図面では図示を省略している。 Next, a method of attaching the connector housing 3 will be described. The mounting hole 2 is formed in the vehicle interior material 1. In this case, as shown in FIG. 11, the hole 66 formed at the time of manufacturing can be machined to enlarge the mounting hole 2. The main body 4 of the connector housing 3 is inserted into the mounting hole 2 from the front side of the interior material 1. When the main body 4 is inserted into the mounting hole 2 as shown in FIG. 8, the inclined guide surface 24 of the locking piece 21 comes into contact with the mounting hole 2, and the locking piece 21 is elastically deformed so as to be pushed inward to guide the inclination. When the surface 24 passes through the mounting hole 2, the locking piece 21 is restored, the rear surface of the locking edge 7 of the connector receiving member 5 abuts on the outer surface of the interior material 1, and the surface 24 abuts on the opening edge of the mounting hole 2. The outer surface 26 of the tip of the locking piece 21 is close to or abuts on the outer surface 26. In this state, even if a force for moving the connector housing 3 to the front side is applied, the rear side corner portion 2K of the mounting hole 2 abuts on the oblique locking surface portion 25B, so that misalignment can be prevented. In addition, although the harness 57 of the connector 8 is shown in FIGS. 9 and 11, the illustration is omitted in other drawings.

この後、コネクタ取付部１８内に車両側のコネクタ８を挿入し、コネクタケース５５の側面後部の嵌合突部５６が前記開口部３１に嵌入することにより、前記コネクタ取付部１８内にコネクタ８が着脱可能に固定される。これにより左右の壁部１１，１１の上部間の間隔を狭めようとする力に対してコネクタ８が対抗して変形が防止され、また、左右の壁部１１、１１の下部間に基板４１が配置されているため、前記変形が防止され、さらに、コネクタ８により上部左右の係止片２１，２１の内側への変形が防止される。 After that, the connector 8 on the vehicle side is inserted into the connector mounting portion 18, and the fitting protrusion 56 at the rear side surface of the connector case 55 is fitted into the opening 31 to fit the connector 8 into the connector mounting portion 18. Is detachably fixed. As a result, the connector 8 opposes the force that tries to narrow the space between the upper portions of the left and right wall portions 11 and 11 to prevent deformation, and the substrate 41 is placed between the lower portions of the left and right wall portions 11 and 11. Since it is arranged, the deformation is prevented, and further, the connector 8 prevents the upper left and right locking pieces 21 and 21 from being deformed inward.

従って、本体４の左右上下の係止片２１，２１，２１，２１の内側への変形が防止されるため、コネクタ８，９へのＵＳＢコネクタ１０の挿脱の際、コネクタハウジング３に力が加わっても、コネクタハウジング３が抜けることなく、安定した取付状態が得られ、特に、ＵＳＢコネクタ１０の抜き取り時の荷重に耐えることができる取付強度を確保でき、特に振動条件の車両用などに適した構造となる。 Therefore, since the inward deformation of the left, right, top, and bottom locking pieces 21, 2, 1, 21, and 21 of the main body 4 is prevented, a force is applied to the connector housing 3 when the USB connector 10 is inserted and removed from the connectors 8 and 9. Even if it is added, a stable mounting state can be obtained without the connector housing 3 coming off, and in particular, mounting strength that can withstand the load when the USB connector 10 is pulled out can be secured, and it is particularly suitable for vehicles under vibration conditions. It has a structure.

また、取付作業においては、コネクタハウジング３を一方向から挿入し、コネクタハウジング３に装着する必要があるコネクタ８を他側で装着するから、取付作業性に優れたコネクタハウジングの取付構造を提供することができる。さらに、コネクタ挿入孔６，６を上下に配置することにより、左右に配置する場合に比べて、スペースを取らず、省スペース化が可能になる。 Further, in the mounting work, since the connector housing 3 is inserted from one direction and the connector 8 that needs to be mounted on the connector housing 3 is mounted on the other side, a mounting structure of the connector housing having excellent mounting workability is provided. be able to.
