As shown in FIGS. 5, 6, and 10, the lower shell 62 is formed in a substantially cylindrical shape that is horizontally long in the width direction, and is open in the vertical direction. In addition, the wire introduction part 23 can be accommodated in the lower shell 62 from above. When the wire introduction part 23 is accommodated in the lower shell 62, the lower shell 62 is placed around the entire circumference of the wire introduction part 23. It will be in the state covered over. In addition, the shield shell 60 is configured by assembling the upper shell 61 from the rear to the connecting portion 24 after assembling the lower shell 62 to the electric wire introduction portion 23.
A braided wire (not shown) is connected to the outer peripheral surface of the lower shell 62 so that the pair of electric wires 50 introduced into the electric wire introduction portion 23 are shielded collectively.

A bolt insertion hole 31 through which a fastening bolt (an example of a “fastening member”) 32 is inserted is formed in the electric wire introduction portion 23 of the housing 20. The bolt insertion hole 31 is formed so as to penetrate the substantially central portion in the width direction of the electric wire introduction portion 23 in the front-rear direction. In other words, the bolt insertion hole 31 is formed in the electric wire introduction part 23 using the wide partition wall 26 that partitions the pair of cavities 25 through which the electric wires 50 are inserted.
The fastening bolt 32 is set to have a length that is greater than the total length of the length dimension of the electric wire introducing portion 23 in the front-rear direction, the thickness of the upper shell 61, and the thickness of the lower shell 62. The rear surface of the shield case 100 can be fastened to a lower fastening hole 104 provided below the attachment hole 101.

  A mounting seat 33 is formed on the opening edge of the bolt insertion hole 31 on the front surface of the electric wire introducing portion 23 so as to protrude forward. The mounting seat 33 is in close contact with the rear surface of the shield case 100 when the case fitting portion 22 of the housing 20 is fitted into the mounting hole 101 of the shield case 100, so that the shield case 100 and the wire introduction portion 23 are connected. It plays the role of filling in the gaps between them.

On the other hand, a lower side insertion hole 62 </ b> A provided corresponding to the bolt insertion hole 31 of the wire introduction portion 23 is formed at the substantially central portion in the width direction on the rear surface of the lower shell 62. When assembled, the lower side insertion hole 62 </ b> A overlaps behind the bolt insertion hole 31 of the electric wire introduction portion 23.
Further, as shown in FIGS. 5 and 10, an extending piece 65 having an upper side insertion hole 65 </ b> A is formed at the substantially central portion in the width direction on the rear surface of the upper shell 61. The extension piece 65 extends downward from the lower end portion of the upper shell 61, and when the upper shell 61 is assembled to the connecting portion 24, the bolt insertion hole 31 of the wire introduction portion 23 and the lower side insertion hole of the lower shell 62. The extension piece 65 is overlapped behind 62A, and the bolt insertion hole 31, the lower side insertion hole 62A, and the upper side insertion hole 65A are continuous.
Then, by continuously inserting the fastening bolt 32 into the upper side insertion hole 65A, the lower side insertion hole 62A, and the bolt insertion hole 31, and tightening the fastening bolt 32 into the lower side fastening hole 104 of the shield case 100, The electric wire introduction part 23, the upper shell 61, and the lower shell 62 are fastened together and fixed to the shield case 100.

That is, the shield connector 10 penetrates not only the position of the pair of bolt fastening portions 64 provided on both sides in the width direction of the attachment piece 63 of the upper shell 61 but also the substantially central portion in the width direction of the shield shell 60 and the wire introduction portion 23. The fixing bolts 32 are fixed in a well-balanced manner at a total of three positions including the position of the fastening bolt 32.
Further, when the fastening bolt 32 is tightened in the lower fastening hole 104, the upper shell 61 and the lower shell 62 are integrally fixed to form the shield shell 60, and the entire housing 20 is covered with the shield shell 60. It has become.

Further, the mounting seat 33 of the electric wire introduction part 23 is in close contact with the rear surface of the shield case 100, and the gap between the shield case 100 and the electric wire introduction part 23 is filled. Thereby, it can suppress that the electric wire introduction part 23 rattles in the front-back direction compared with the case where the electric wire introduction part is separated back from the rear surface of the shield case.

  Next, the lower shell 62 is attached to the electric wire introducing portion 23 from below, and the upper shell 61 is subsequently attached to the connecting portion 24 from the rear, whereby the shield shell 60 is configured, and the entire housing 20 is covered by the shield shell 60. . At this time, the lower side insertion hole 62A of the lower shell 62 is overlapped behind the bolt insertion hole 31 of the electric wire introduction part 23, and the extension piece 65 is overlapped, and the bolt insertion hole 31, the lower side insertion hole 62A and the upper are overlapped. The side insertion hole 65A is in a continuous state. Then, the fastening bolt 32 is continuously inserted through the upper side insertion hole 65A, the lower side insertion hole 62A, and the bolt insertion hole 31, and the fastening bolt 32 is tightened into the lower side fastening hole 104 of the shield case 100. The shield member 10 is fixed to the shield case 100 by fastening the three members of the introduction portion 23, the upper shell 61, and the lower shell 62 together. As a result, the upper shell 61 and the lower shell 62 are fixed together, and the lower portion of the shield connector 10 at the substantially central portion in the width direction is fixed by the fastening bolt 32.

  Finally, the bolt BT is inserted into a pair of bolt fastening portions 64 provided on both sides in the width direction of the mounting piece 63 of the upper shell 61 and the bolts BT are fastened to the pair of upper fastening holes 102, respectively. As shown in FIG. 9, the attachment piece 63 is fixed to the shield case 100 in the upper part of the shield connector 10, and the shield shell 60 is electrically connected to the shield case 100.

That is, according to this embodiment, since the fastening bolt 32 is fastened in the front-rear direction at the wire introduction portion 23 where the wire 50 is introduced into the housing 20, even if the wire 50 vibrates greatly with the vibration of the vehicle, The vibration can be blocked at the initial position where the vibration is transmitted to the shield connector 10. Further, the position of the pair of bolt fastening portions 64 provided on both sides in the width direction of the mounting piece 63 positioned on the upper side in the shield connector 10 and the substantially central portion in the width direction of the electric wire introduction portion 23 positioned on the lower side in the shield connector 10. Since the shield connector 10 is fixed in a well-balanced manner to the shield case 100 at three positions including the fastening bolts 32 penetrating the shield bolt 100, it is ensured that the shield connector 10 is rattled due to bending of the mounting piece 63 or the like. Can be prevented. Thereby, it is possible to suppress the occurrence of a problem between the device-side terminal 112 and the female terminal 42 due to the vibration of the electric wire 50 or the like.
In addition, according to the present embodiment, since the conductive member 40 is connected to the end of the electric wire 50, even if the vibration of the electric wire 50 is transmitted to the conductive member 40, the vibration is the elastic conductor of the conductive member 40. It is possible to reliably suppress the occurrence of a problem between the two terminals 112 and 42 by being absorbed by the terminal 41.

In addition, according to the present embodiment, in order to reduce the height of the housing 20, the length in the width direction between the two electric wire side connection portions 46 is made larger than the length in the width direction between the two conductive member side connection portions 47. In this way, by bending the pair of relay terminals 43 outward in the width direction, a so-called dead space in which the partition wall 26 between the pair of wires 50 in the wire introduction portion 23 becomes wide is generated in the wire introduction portion 23. . However, since the dead bolt (the wide partition wall 26) can be used to allow the fastening bolt 32 to pass through the electric wire introduction portion 23, there is no need to provide a space for passing the fastening bolt 32 in the housing 20 separately. Can be prevented from further increasing in size.
Furthermore, according to the present embodiment, the upper shell 61 and the lower shell 62 can be integrally combined and fixed by the fastening bolt 32 that fixes the housing 20 and the shield shell 60 to the shield case 100. For example, the upper shell 61 There is no need to separately provide a fixing mechanism for fixing the two to the lower shell 62, and the structure of the shield shell 60 can be simplified.
