The cap 6 for accommodating this has one end having a large diameter and the other end having a small diameter, and the small-diameter cable 7 must be pulled back from the small-diameter side in advance. That is, there is a problem that the work is inefficient because the work is carried out first and then returned.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a shield connector capable of improving the workability of assembly.

[0007]

In order to achieve the above-mentioned object, the invention according to claim 1 covers the periphery of a terminal fitting housed inside with a shield electrode, and the outer periphery of an insulation-coated inner wire is a braided wire. In a shielded connector in which the inner wire of a shielded wire whose outer periphery is insulated and covered with insulation is connected to the terminal fitting and the braided wire is connected to the same shield electrode, the shielded wire can be inserted inside. > Holds the cylindrical shield electrode and the shield electrode, and inserts and holds the shield wire inside.

And an attachment having a conductive terminal piece capable of contacting the inner peripheral surface of the.

The invention according to claim 2 is based on claim 1.
In the shielded connector described in the above item 1, the terminal piece of the attachment is formed of a bent spring plate made of a metal plate, and is arranged so as to sandwich the shielded electric wire to be penetrated. Furthermore, the invention according to claim 3 is the shielded connector according to claim 1 or claim 2, wherein the attachment has a base portion for holding the terminal piece, and the base portion faces from the outer surface toward the center. It is configured such that a notch through which the shielded electric wire can penetrate is formed.

Further, the invention according to claim 4 is the shield connector according to claim 1 or 2.
The terminal piece of the attachment has a ring shape that can be inserted into the shield electrode, and has a claw-shaped contact piece that projects toward the center while tilting slightly toward the opening side of the shield electrode, , The attachment is pierced by the shield electric wire and is insertable into the shield electrode, and the tip of the side inserted into the shield electrode is brought into contact with the inclined surface of the contact piece to contact the contact piece. It is configured to have a pressing member in which a contact surface is formed so that the tip end is directed toward the center side.

[0010]

In the invention according to claim 1 configured as described above, first, the shield electrode is held in the casing, and the shield wire having the exposed braided wire is inserted and held in the casing. Next, when the attachment is inserted inside the shield electrode with the shield wire penetrating, the terminal piece is in contact with the outer peripheral surface of the shield wire being penetrated, so that the exposed braided wire While conducting, the outer peripheral side is in contact with the inner peripheral surface of the shield electrode to conduct. As a result, the braided wire and the shield electrode are electrically connected. That is, the shield electrode is not directly connected to the shield electric wire, and after the shield electric wire is held by the casing, the attachment is shifted to bring the braided wire and the shield electrode into conduction.

Further, in the invention according to claim 2 configured as described above, the terminal piece formed by the spring plate formed by bending the metal plate is arranged so as to sandwich the shielded electric wire which penetrates therethrough, When the shielded wire is penetrated, it is pressed from the surroundings to support it stably.

That is, even if the shielded electric wire is not passed through in advance, if the shielded electric wire is pushed into the notch of the base portion from the side surface side, the attachment is attached to the shielded electric wire to be in a penetrating state.

Further, in the invention according to claim 4 configured as described above, the ring-shaped terminal piece is inserted into the shield electrode, and the shield wire penetrates therein. At this time, the contact piece projects toward the shield electric wire side while inclining toward the opening side of the shield electrode. When the pressing member is inserted into the shield electrode, the contact surface at the tip contacts the inclined surface of the terminal piece, and the terminal piece is curved toward the center side as it is pushed. Then, the tip of the terminal piece comes into close contact with the shielded wire passing through the center.

[0013]

As described above, according to the present invention, the shield electrode and the shielded electric wire are separately assembled. Therefore, the shield electrode and the shielded electric wire are assembled before they are inserted into the casing as in the prior art. , It can be assembled without complicated hands such as pulling back at the end. In particular, since the attachment is displaced with respect to the shielded electric wire, the work of holding the shielded electric wire by the casing and the work of attaching the attachment are separate, and can be performed with a small force as compared with the case of performing them at the same time.

According to the second aspect of the present invention, since the terminal piece formed of the spring piece is supported so as to be pressed down from around the shielded wire, the connection with the shielded wire is stable. Furthermore, according to the invention of claim 3, it is not necessary to previously attach the attachment to the shielded electric wire,
Assembly becomes easier. Further, according to the invention of claim 4, since the ring-shaped terminal piece is individually inserted into the shield electrode, the insertion force can be made extremely small. In addition, since the contact piece is curved and brought into contact with the contact piece, it exhibits springiness and has good contact stability. Further, the decrease in contact pressure due to the creep phenomenon or the like can be suppressed to a minimum.
