- the pair of fixing portions 49 have bolt insertion holes 51.
- the pair of fixing portions 49 are arranged and formed according to the position of the bolt hole 20 of the shield case 14.
- a fastening member 47 is attached to the shield member 41. Specifically, the terminal pressing portion 48 is inserted inside the shield member 41, and the fastening fixing member 47 is mounted so that the fixing portion 49 protrudes from the inside of the opening 46 to the outside.
- a holding portion 43 is formed on the terminal portion 42 of the shield member 41 by bending inward such that the terminal 44 is hidden.
- the tightening fixing member 47 is held in a state where it does not fall off due to the formation of the holding portion 43. After the inward bending, if the part (bag mouth part) that is doubled in the vicinity of the terminal 44 is fixed so as to be partially or completely closed, the fastening member 47 can be more securely removed. It becomes possible to prevent.
- the closing method is the same as in the first and second embodiments.
- the terminal portion 42 of the shield member 41 is inserted outside the cylindrical portion 15 of the shield case 14, and the pair of fixing portions 49 are fastened and fixed by the bolts 35. Accordingly, the terminal portion 42 of the shield member 41 is pressed so as to make surface contact with the one side wall 17 of the shield case 14 by the terminal pressing portion 48 of the fastening member 47. Therefore, the electrical connection of the shield member 41 is completed at the same time as the bolt 35 is fastened and fixed.
- Example 3 has the same effect as Example 2 and Example 1.
- the shield structure is the shield case 14 and the shield case 61, but it is not limited to this.
- it may be a panel member that can be a ground.
- This application is based on a Japanese patent application filed on June 10, 2010 (Japanese Patent Application No. 2010-132585), the contents of which are incorporated herein by reference.
- the shield terminal connection structure and method according to the present invention when connecting the terminal portion of the shield member to the shield structure, the holding portion formed by the terminal portion itself and the conductive fixing held by the holding portion. What is necessary is just to use a member.
- the fixing member is fixed to the shield structure, the terminal portion of the shield member is electrically connected to the shield structure through the fixing member along with the fixing. Therefore, a simple and simple shield terminal connection structure and method for connecting the terminal portion of the shield member to the shield structure can be provided.

Abstract
Description
(1) 複数本の導電路を一括して収容する筒状のシールド部材の端末部分に、該端末部分自身にて保持部を形成するとともに、該保持部に、前記導電路の接続相手側のシールド構造体に対し固定される導電性の固定部材を電気的に接触させつつ保持することによりなるシールド端末接続構造。
上記(1)の構成のシールド端末接続構造によれば、シールド部材の端末部分をシールド構造体に接続するにあたり、端末部分自身にて形成される保持部と、この保持部に保持される導電性の固定部材とを用いればよい。固定部材をシールド構造体に固定すると、この固定に伴い、シールド部材の端末部分は固定部材を介してシールド構造体に電気的に接続される。そこで、シールド部材の端末部分をシールド構造体に接続するための簡単且つ簡素なシールド端末接続構造を提供することができるという効果を奏する。
本出願は、2010年6月10日出願の日本特許出願(特願2010-132585)に基づくものであり、その内容はここに参照として取り込まれる。
