上述したシールドコネクタ１によれば、電線２に外装される編組導体３１と、導電性を有するシールドシェル３２と、を備え、編組導体３１は、筒状の編組導体本体３１１と、該編組導体本体３１１の軸方向の前端部３１１ｆ（端部）から引き出された引出し部３１２と、を有し、引出し部３１２が、シールドシェル３２に電気的に接続されている。これによれば、従来技術の如く、シールドリングを加締めることで編組導体３１をシールドシェル３２に電気的に接続せずとも、編組導体３１から引き出された引出し部３１２が、シールドシェル３２に電気的に接続されることで、編組導体３１とシールドシェル３２との電気的接続が得られる。これにより、シールドリングを省略することができるから、部品点数を削減しつつ、シールドリングを加締める手間を省略することができる。さらに、シールドシェル３２において、シールドリングを加締めるための場所が不要とされる分だけシールドシェル３２の小型化を図ることができる。即ち、軽量化及び小型化を図ることができ、製造コストの低減を図ることができる。さらに、腐食の抑制を図ることができる。 According to the above-described shield connector 1, the braid conductor 31 that is sheathed on the electric wire 2 and the conductive shield shell 32 are provided, and the braid conductor 31 includes the tubular braid conductor body 311 and the braid conductor body. 311 and a lead-out portion 312 pulled out from an axial front end portion 311f (end portion), and the lead-out portion 312 is electrically connected to the shield shell 32. According to this, as in the prior art, even if the braided conductor 31 is not electrically connected to the shield shell 32 by caulking the shield ring, the lead-out portion 312 pulled out from the braided conductor 31 is electrically connected to the shield shell 32. Are electrically connected, the electrical connection between the braided conductor 31 and the shield shell 32 is obtained. Thereby, since the shield ring can be omitted, it is possible to reduce the number of parts and the time and effort for crimping the shield ring. Further, in the shield shell 32, the shield shell 32 can be downsized by the amount that a place for crimping the shield ring is unnecessary. That is, the weight and the size can be reduced, and the manufacturing cost can be reduced. Further, it is possible to suppress corrosion.

また、引出し部３１２が接続されるＬＡ端子３４（端子）を備え、該ＬＡ端子３４は、シールドシェル３２にボルト固定されている。これによれば、シールドコネクタ１のシールド接触信頼性は、ワッシャ付きボルト１０が緩むことがない限り継続される。即ち、シールド接触信頼性の向上を図ることができる。 Further, the LA terminal 34 (terminal) to which the drawer portion 312 is connected is provided, and the LA terminal 34 is bolted to the shield shell 32. According to this, the shield contact reliability of the shield connector 1 is continued unless the bolt 10 with a washer is loosened. That is, the shield contact reliability can be improved.

また、ＬＡ端子３４（端子）とシールドシェル３２とが共締めされている。これによれば、ＬＡ端子３４に接続された編組導体３１とシールドシェル３２との固定及びシールド接続を同時にできるから作業性の向上を図ることができる。さらに、ＬＡ端子３４の圧着接続部３４２に、編組導体３１の引出し部３１２を圧着接続し、ＬＡ端子３４、及びシェル固定部３２１を、ワッシャ付きボルト１０を用いて筐体に共締めした場合には、編組導体３１、ＬＡ端子３４、シールドシェル３２及び筐体の固定及びシールド接続を同時にすることができるから、より一層、作業性の向上を図ることができる。 Further, the LA terminal 34 (terminal) and the shield shell 32 are fastened together. According to this, since the braided conductor 31 connected to the LA terminal 34 and the shield shell 32 can be fixed and shielded at the same time, workability can be improved. Furthermore, when the lead-out portion 312 of the braided conductor 31 is crimp-connected to the crimp connection portion 342 of the LA terminal 34, and the LA terminal 34 and the shell fixing portion 321 are jointly fastened to the housing using the bolt 10 with washer. Since the braided conductor 31, the LA terminal 34, the shield shell 32, and the housing can be fixed and shielded at the same time, the workability can be further improved.
