The inner walls of the front end portion 6 of the inner wall portion 6 have communication walls 17a to 17d at the same intervals so that the rear end portion of the inner cylindrical portion 11 is held suspended.
Are formed. Thereby, the shield electrode insertion holes 18a to 18d that are continuous from the outer peripheral surface of the inner tubular portion 11 to the inner peripheral surface of the terminal fitting insertion portion 16 are formed. The four shield electrode insertion holes 18a to 18d form a circular through hole as a whole along the outer circumference of the inner cylindrical portion 11. At the rear end of the inner tubular portion 11, a tubular waterproof seal wall 19a is formed from the inner wall of the hood portion 12 so that the inner tubular portion 11 covers the portion in which the terminal fitting insertion portion 16 is suspended.
Further, a flexible lock arm 19b is provided on the upper surface of the hood portion to engage with and hold the mating connector when the mating connector is fitted and connected.

The shield electrode (shell) 20 has a cylindrical shape in which a metal plate is bent to have an inner diameter corresponding to the outer diameter of the inner cylindrical portion 11, and as shown in FIG. 4, the shield electrode (shell) faces from the rear end side to the front end side. 4 notches 21 are formed.

When the communication walls 17a to 17d are inserted until reaching the tip of the cut 21, the shield electrode 20
The rear end is in a state of being inserted into the terminal fitting insertion portion 16.
In addition, a wedge-shaped locking claw 22 that projects toward the inside of each cut 21 is formed in the vicinity of each cut 21, and when the shield electrode 20 is inserted all the way as described above, the lock claw 22 is formed. It cuts into the communication walls 17a to 17d to prevent the shield electrode 20 from coming off. The shield electrode 20 is arranged around the inner cylindrical portion 11 along the outer peripheral surface thereof, and inside the terminal fitting insertion portion 16 is arranged along the inner peripheral surface of the terminal fitting insertion portion 16.

In the present embodiment, the rear end of the shield electrode 20 is divided into four pieces, and four communicating walls 17 are formed in accordance with this.
Although a to 17d are formed, the number can be increased or decreased as necessary. The shield electrode 20 does not necessarily have to be integrated, and may be formed by dividing a cylinder. Further, it is not always necessary to form the plate piece, and it may be a rod-shaped body. The cap 30 has a substantially cap shape capable of covering the tip of the inner cylindrical portion 11. 5 to 7
As shown in FIG. 7, a plate-like double locking piece 31 is formed so as to project on the inner bottom surface of the cap 30 that faces the cutout portion 15 when mounted. A groove 31a is formed in the central part of the upper surface of the plate along the lance 14 and aligned with the insertion direction, and two locking projections 32a, 32b projecting upward are formed on the side parts. . Although not shown, the upper wall surface of the cut portion 15 is formed with a groove into which the locking protrusions 32a and 32b can be engaged.

The cap 30 has an inner diameter that matches the outer diameter of the shield electrode 20, and can be attached to the tip portion of the inner cylindrical portion 11 to which the shield electrode 20 is attached.
Further, four windows 33a to 33d are formed on the side surface at the same intervals, and the shield electrode 20 covering the inner cylindrical portion 11 is exposed to the outside through the windows 33a to 33d. The front ends of the windows 33a to 33d communicate with the front surface of the cap 30, and the shield electrode 20 is exposed from the front end to the side surface. Further, the opening end of the cap 30 is formed with a flange 34 that is expanded in the radial direction, and this flange 34 has a diameter slightly larger than the end portion of the waterproof seal wall 19a. When the ring-shaped rubber seal 40 shown in FIG. 8 is attached to the waterproof seal wall 19a, the flange 34 presses the front end thereof to prevent the rubber seal 40 from coming off. The front side of the cap 30 is also formed with a mating terminal fitting insertion port 35 into which a male terminal fitting can be inserted. On the other hand, the electric wire 80 covers the inner wire 81 with a shield wire 82 made of a braided wire. In addition, the outermost periphery is covered with a resin, and as shown in FIG.
The tubular rubber plug 60 forming 1 is preliminarily inserted, and the terminal fitting 50 and the attachment 70 are pressure-bonded to each other.

The attachment 70 shown in FIG. 10 is obtained by first pressing a metal plate as shown in FIG.
It is molded together with 0, and is bent and formed three-dimensionally in the same manner as the terminal fitting 50 is bent. The attachment 70 is pressed in a straight line with the terminal fitting 50 via a carrier, and has a small-diameter connection portion 71 on which the shield wire 82 can be wound and crimped on the carrier side. The small-diameter connecting portion 71 has two sets of flat plate pieces that extend in an alternating manner, and each is bent in a U shape. A large-diameter connecting portion 73 is continuous from the small-diameter connecting portion 71 via an intermediate connecting portion 72 extending to the opposite side of the carrier. The large-diameter connecting portion 73 forms a strip plate parallel to the carrier, and has a plurality of cuts 73a formed on the tip side. When the strip plate is bent in a ring shape, the side where the notch 73a is formed has a slightly large diameter,
The entire diameter is such that it can be inserted into the inner circumference of the shield electrode 20. By forming the notch 73a, the end on the large diameter side can be slightly bent inward. Further, the step portion 61 of the rubber plug 60 can be inserted into the inner peripheral side of the large diameter connection portion 73, and the attachment 70 holds the large diameter connection portion 73 from the inside by the rubber plug 60,
The side of the large-diameter connection portion 73 is held.

Next, the operation of this embodiment having the above configuration will be described. In the electric wire 80, the electric wire 80 is inserted from the side opposite to the step 61 of the rubber plug 60, and the tip portion is peeled off in stages. That is, the core wire of the extension wire 81 is exposed from the tip, the covered portion of the extension wire 81 is exposed, and then the shield wire 82 of the braided wire is exposed. Here, the terminal fitting 50 and the attachment 70 are formed on both sides of one carrier, and are simultaneously crimped to the electric wire 80 when crimped by the applicator. Therefore, the shield wire 82 is attached to the barrel portion of the terminal fitting 50 while the extension wire 81 is aligned.
It is peeled off so as to face the U-shaped opening of the small diameter connecting portion 71 at 0. For crimping with this applicator, use a mold on both sides of the carrier to
The barrel portion 0 is crimped, and the U-shaped opening portion of the small diameter connecting portion 71 is caulked and fixed so as to be wound around the shield wire 82. At that time, the carrier is cut off. After that, the rubber plug 60 is moved to the attachment 70 side, and the small-diameter step portion 61 is inserted inside the large-diameter connection portion 73. By simultaneously connecting the attachment 70 and the terminal fitting 50 in this manner, the number of steps is reduced. However, it is not always necessary to perform it simultaneously with the terminal fitting 50, and it is also possible to perform it separately.

When the step 61 of the rubber plug 60 is not provided, the small-diameter connecting portion 71 of the attachment 70 is wound around and fixed to the outer circumference of the electric wire 80, but the large-diameter connecting portion 73 is unstable via the intermediate connecting portion 72. It is in a state. However, the rubber plug 60, which is a separate component, supports the large-diameter connecting portion 73 from the inside, so that it is stably held. Further, since the rubber plug 60 has elasticity, it is possible to allow the large-diameter connecting portion 73 to slightly bend inward as described later. That is, in this embodiment, the rubber plug 60 having this step portion 61 constitutes an adapter. Of course, the adapter itself does not necessarily have a waterproof function, but by using the rubber plug 60 in this way,
It is possible to prevent an increase in the number of parts.

On the other hand, on the housing 10 side, a rubber seal 40 is attached to the waterproof seal wall 19a inside the hood portion 12, and the shield electrode 20 is put on the outer periphery of the inner cylinder portion 11 from the side of the cut 21. The communication walls 17a to 17d are aligned with the notches 21 and the shield electrode 20 is pushed in until the communication walls 17a to 17d reach the deepest part of the notches 21. At this position, the shield electrode 20
Is substantially flush with the front end of the inner tubular portion 11, and the locking claws 22 bite into the side surfaces of the communication walls 17a to 17d to prevent the shield electrode 20 from coming off. In this embodiment, the locking claws 22 bite into and fix the side surfaces of the communication walls 17a to 17d, but a lance-shaped claw that rises toward the inner surface of the shield electrode 20 is formed, and the claws are inserted into the shield electrode insertion holes. It may be locked when it enters the terminal fitting insertion portion 16 through the holes 18a to 18d.

Next, the cap 30 is attached to the inner cylinder portion 11 and the tips of the shield electrode 20. The shield electrode 20 is inserted so that the opening surface of the cap 30 faces the inner cylindrical portion 11 side and the shield electrode 20 enters the inside of the cap 30. As the shield electrode 20 is covered, the double locking piece 31 enters into the notch 15 at the front end of the inner cylindrical portion 11, and engages with the tip side engagement formed on the upper surface of the double locking piece 31. Stop projection 32
a engages with the groove on the upper wall surface of the cut portion 15. At this time, since the other locking protrusion 32b is in front of the notch 15, the cap 30 is temporarily locked by both locking protrusions 32a and 32b. Further, at this position, the double locking piece 31 is not inserted to the lower surface of the lance 14, and the lance 14 can bend downward. FIG. 12 is a sectional view showing a state in which the shield electrode 20 and the cap 30 are thus mounted.

The electric wire 80 on which the terminal fitting 50 and the attachment 70 are mounted as described above is inserted from the side of the terminal fitting insertion portion 16 of the housing 10. When the terminal fitting 50 is inserted into the terminal accommodating chamber 13, the corner portion of the front end pushes down the protrusion 14a of the lance 14, and when the terminal fitting 50 is inserted to the deepest portion, the opening (not shown) formed on the lower surface of the terminal fitting 50 is the same. The lance 14 returns to face the protrusion 14a. The lance 14 is temporarily pushed into the notch 15 until it is restored after being pushed down. As the terminal fitting 50 enters the terminal accommodating chamber 13, the attachment 70 attached to the electric wire 80 and the rubber plug 60.
Also enters the terminal metal fitting insertion portion 16. When the rubber plug 60 starts to be inserted into the terminal metal fitting insertion portion 16, the large-diameter connection portion 73 of the attachment 70 is inserted into the terminal metal fitting insertion portion 16.
It is inserted while being slightly bent inward by the inner peripheral wall surface of. Then, when the terminal fitting 50 is inserted to the deepest part of the terminal accommodating chamber 13, the large-diameter connecting portion 73 enters into the end portion of the shield electrode 20 and is pressed inward, so that it is electrically conducted, and Rubber stopper 60
Is closely attached to the inner peripheral wall surface of the terminal fitting insertion portion 16 for waterproofing.

As described above, when the cylindrical shield electrode 20 is inserted from one side of the housing 10 and the electric wire 80 to which the attachment 70 is attached is inserted from the other side of the housing 10, the electric wire 80 is attached.
The diameter is substantially expanded by 0 and is connected to the shield electrode 20. Therefore, the connection with the shield electrode 20 becomes extremely easy. Further, it is not necessary to pass the electric wire 80 in advance.
Then, the cap 30 is inserted all the way. Then, the double locking piece 31 advances to the inside of the cut portion 15, and the other locking projection 32b that remains is engaged with the groove on the upper wall surface of the cut portion 15, so that the cap 30 is prevented from coming off. Since the cap 30 has such a large diameter that it can cover the tip of the shield electrode 20, the cap 3
By preventing 0 from coming off, the shield electrode 20 is prevented from coming off.

When the double locking piece 31 enters the notch 15, the lance 14 cannot bend downward.
It is impossible for the terminal fitting 50 to come off unless the lance 14 bends downward once and the projection 14a retracts. Therefore, the double locking piece 31 thus supporting the lance 14 in the cut portion 15 like a hollow can reliably prevent the terminal fitting 50 from coming off. Further, since the flange 34 of the cap 30 is fixed at the end portion of the waterproof seal wall 19a by fixing the cap 30, the rubber seal 40 abuts when the cap 30 is about to come out, so that the cap 30 can be prevented from coming off.

The shield connector having such a structure is provided with a cylindrical shield electrode whose tip is divided into four parts corresponding to the windows 33a to 33d and a male side metal fitting held in the shield electrode. Connect the connector. The shield electrode is exposed through the windows 33a to 33d. The male terminal fitting is connected to the shield electrode 20, and the male terminal fitting is held in the terminal accommodating chamber 13 by the female terminal fitting 5.
Connect with 0. Although the shield electrode 20 and the electric wire 80 are inserted in different directions in the above-mentioned embodiments, the flexibility in assembling is improved by performing them separately even when they are inserted from the same direction.
