Further, on the peripheral edge portion 54, vapor-deposition plating pressure-contact pieces 57 having a V-shape are formed obliquely upward at intervals of 120 degrees so as to be offset from the outer-peripheral shell pressure-contact pieces 56 by 60 degrees. In addition, notches 60 are formed on both sides to give elasticity.

このようにして形成されたシールドプレート５２を前記外周シェル４０の下方から圧入すると、外周シェル圧接片５６が係止段部４０ａを乗り越えて係止段部４０ａに係止するとともに、蒸着メッキ圧接片５７がカメラ収容樹脂ケース２６の内面の蒸着メッキ２７に圧接する。この時、外周シェル圧接片５６の先端部が外周シェル４０の係止段部４０ａに圧接し、蒸着メッキ圧接片５７の屈曲部がカメラ収容樹脂ケース２６の蒸着メッキ２７に圧接し、シールドプレート５２の平面部５３と周縁部５４は、外周シェル４０の側面、突起部５８の底面と側面との間に隙間５９が生ずるようにする。この結果、外周シェル圧接片５６が係止段部４０ａに、蒸着メッキ圧接片５７が蒸着メッキ２７にそれぞれより確実に圧接して電気的に接続される。
なお、前記外周シェル４０が円筒形であるため、外周シェル圧接片５６と蒸着メッキ圧接片５７は、それぞれ１２０度間隔で３個ずつとしたが、前記外周シェル４０の形状や目的に応じて２個、４個、５個、それ以上などとすることができる。 When the shield plate 52 thus formed is press-fitted from below the outer shell 40, the outer shell pressure contact piece 56 rides over the locking step portion 40a and locks on the locking step portion 40a, and at the same time, the vapor deposition plating pressure contact piece is pressed. 57 is pressed against the vapor deposition plating 27 on the inner surface of the camera housing resin case 26. At this time, the tip of the outer shell pressure contact piece 56 is in pressure contact with the locking step portion 40a of the outer shell 40, the bent portion of the vapor deposition plating pressure contact piece 57 is in pressure contact with the vapor deposition plating 27 of the camera housing resin case 26, and the shield plate 52. The flat surface portion 53 and the peripheral edge portion 54 form a gap 59 between the side surface of the outer peripheral shell 40 and the bottom surface and the side surface of the protruding portion 58. As a result, the outer shell pressure contact piece 56 and the evaporation plating pressure contact piece 57 are more surely pressed and electrically connected to the locking step portion 40a and the deposition plating 27, respectively.
Since the outer shell 40 has a cylindrical shape, the outer shell pressure contact pieces 56 and the vapor deposition plating pressure contact pieces 57 are three at 120° intervals. It can be 4, 4, 5 or more.

前記カメラ収容樹脂ケース２６に同軸コネクタ２３を組み込み、シールドプレート５２で圧接したら、カメラ収容樹脂ケース２６の開口部から基板側コネクタ３１の接続ピン４４と絶縁部４５とシェル部４６を圧入する。すると、接続ピン４４は下部コンタクト３３に挿入接続し、シェル部４６は下部シェル３９に接続する。前記基板側コネクタ３１は、配線基板２８を経てカメラモジュール２９に接続され、レンズ３０で外部の映像を内部の撮像素子に集光する。
前記配線基板２８は、カメラ収容樹脂ケース２６の蒸着メッキ２７で包囲されて電磁ノイズなどの電磁波から遮蔽される。 When the coaxial connector 23 is assembled into the camera housing resin case 26 and pressure-contacted by the shield plate 52, the connection pin 44, the insulating portion 45, and the shell portion 46 of the board-side connector 31 are press-fitted from the opening of the camera housing resin case 26. Then, the connection pin 44 is inserted and connected to the lower contact 33, and the shell portion 46 is connected to the lower shell 39. The board-side connector 31 is connected to the camera module 29 via the wiring board 28, and the lens 30 collects an external image on an internal image sensor.
The wiring board 28 is surrounded by the vapor deposition plating 27 of the camera housing resin case 26 and shielded from electromagnetic waves such as electromagnetic noise.

このようにしてカメラ収容樹脂ケース２６に同軸コネクタ２３を組み込み、カメラモジュール２９を接続して車体２２の所定位置に取り付けられる。
前記カメラ収容樹脂ケース２６の反対側に突出した同軸コネクタ２３の嵌合筒部４３に同軸ケーブル２４を接続した中継ジャック２５を差し込む。すると、中継ジャック２５の嵌合筒体５１が嵌合筒部４３の外周に沿って嵌合され、中継ジャック２５の同軸側シェル５０が同軸コネクタ２３の上部シェル３８に接続するとともに、同軸ケーブル２４の同軸芯線４８に接続された同軸側コンタクト４７が同軸コネクタ２３の上部コンタクト３２に接続される。
このようにして組み立てと接続を完了する。 In this way, the coaxial connector 23 is assembled in the camera housing resin case 26, the camera module 29 is connected, and the camera module 29 is mounted at a predetermined position of the vehicle body 22.
The relay jack 25 to which the coaxial cable 24 is connected is inserted into the fitting cylindrical portion 43 of the coaxial connector 23 that protrudes on the opposite side of the camera housing resin case 26. Then, the fitting cylinder 51 of the relay jack 25 is fitted along the outer periphery of the fitting cylinder portion 43, the coaxial side shell 50 of the relay jack 25 is connected to the upper shell 38 of the coaxial connector 23, and the coaxial cable 24 is connected. The coaxial side contact 47 connected to the coaxial core wire 48 is connected to the upper contact 32 of the coaxial connector 23.
In this way, assembly and connection are completed.
