In the shielded electric wire as described above, the coated electric wire and the braided conductor are generally prepared as separate members independent of each other, and the braided conductor is covered on the coated electric wire in the process of manufacturing the shielded electric wire. Therefore, it is desirable to fix the covered wire to the braided conductor in order to suppress the relative movement (positional deviation) between the covered wire and the braided conductor. On the other hand, from the viewpoint of weight reduction and cost reduction of the shielded electric wire, it is desirable to reduce the number of parts used for such fixing as much as possible.

The present invention has been made in view of the above circumstances, and an object of the present invention is to integrally have a function of fixing a coated electric wire and a braided conductor included in a shielded electric wire and a function of grounding the braided conductor.

As a result, the grounding member can be attached to the position determined by the first member by a simple procedure. Therefore, the workability of the work of attaching the grounding member to the shielded electric wire can be improved.

According to the shielded electric wire with a grounding member having the configuration of (4) above, the first member cannot move relative to the braided conductor while the first member of the grounding member presses the braided conductor toward the covered electric wire. It is fixed. By this pressing, the positional deviation between the braided conductor and the covered electric wire is suppressed. Further, the second member is fixed to the first member so as not to be relatively movable, and then the third member is fixed so as to sandwich the braided conductor with the outer peripheral surface of the second member. As a result, the contact area between the second member, the third member, and the braided conductor can be increased. Therefore, if the grounding member is connected to the grounding object (body frame or the like), the electromagnetic noise collected by the braided conductor can be efficiently emitted to the grounding object through the grounding member. Further, since the first member is fixed to the braided conductor so as to be relatively immovable, if the second member and the third member are attached to the shielded electric wire with the first member as a reference, the grounding member can be accurately positioned at the designed position. It can also be attached.

Therefore, the shielded electric wire with a grounding member having the present configuration can integrally have a function of fixing the coated electric wire and the braided conductor included in the shielded electric wire and a function of grounding the braided conductor.

<Embodiment>
Hereinafter, the shielded electric wire 1 to which the grounding member 2 according to the embodiment of the present invention is attached will be described with reference to the drawings.

As shown in FIG. 1, the shielded electric wire 1 includes a covered electric wire 10 composed of a core wire 11 and an insulator 12 covering the core wire 11, and a tubular braided conductor 20 covering the coated electric wire 10. By crimping and fixing the grounding member 2 to the braided conductor 20 of the shielded electric wire 1, the shielded electric wire 1 to which the grounding member 2 as shown in the overall image of FIG. 1 is attached is manufactured.

The grounding member 2 is attached so that the braided conductor 20 of the shielded electric wire 1 emits electromagnetic noise or the like cut off and collected toward a grounding target (for example, a vehicle body frame of an automobile). That is, by connecting the grounding member 2 to the grounding object (body frame or the like), electromagnetic noise or the like collected by the braided conductor 20 can be discharged to the grounding object through the grounding member 2.

In this example, the braided conductor 20 is formed so as to be exposed to the outside. However, the shielded electric wire 1 may further include an insulating outer skin (sheath) that covers the outer periphery of the braided conductor 20 if necessary.

As shown in FIG. 1, the metal grounding member 2 includes a shield stopper 30, a shield terminal 40, and a shield ring 50. Hereinafter, with reference to FIGS. 2 and 3, first, each member constituting the grounding member 2 before crimping will be described in order.

As shown in FIG. 2, the metal shield stopper 30 is a cylindrical first main body 31 and a circle extending radially outward from one end in the axial direction of the first main body 31. It integrally has a plate-shaped flange portion 32. The first main body 31 is later fixed to the braided conductor 20 of the shielded wire 1. Notches 33 recessed inward in the radial direction are formed at a plurality of locations (in this example, two locations corresponding to both ends of the diameter) in the circumferential direction of the outer peripheral edge of the flange portion 32.

The metal shield terminal 40 integrally has a cylindrical second main body portion 41 and a hood portion 42 extending radially outward from the second main body portion 41. As shown in FIG. 3D, the hood portion 42 has a disk-shaped bottom wall portion 43 extending radially outward from one end in the axial direction of the second main body portion 41, and a bottom. It is composed of a cylindrical cylindrical wall portion 44 extending in the axial direction from the outer peripheral edge of the wall portion 43 in a direction opposite to that of the second main body portion 41.

The hood portion 42 will later cover the flange portion 32 of the shield stopper 30 and be fixed to the flange portion 32. At positions on the inner wall surface of the cylindrical wall portion 44 that are separated from the bottom wall portion 43 by the plate thickness of the flange portion 32 in the axial direction, a plurality of locations in the circumferential direction (this) so as to correspond to the notches 33 of the flange portion 32. In the example, protrusions 45 projecting inward in the radial direction are formed at two locations corresponding to both ends of the diameter.

In this example, the protrusion 45 is formed by subjecting a corresponding portion of the cylindrical wall portion 44 to be recessed inward in the radial direction (pressing or the like). Therefore, a recess 46 (see FIG. 2 and the like) that is recessed inward in the radial direction is formed at a position corresponding to the protrusion 45 on the outer wall surface of the cylindrical wall portion 44.

The metal shield ring 50 has a cylindrical shape. The shield ring 50 will later be fixed to the second main body 41 of the shield terminal 40.

Next, assembling the shield terminal 40 to the shield stopper 30 will be described with reference to FIG.

First, as shown in FIG. 3A, the flange portion 32 and the hood portion 42 are separated from each other in the axial direction and face each other, and the circumference of the notch 33 of the flange portion 32 and the protrusion 45 of the hood portion 42. The shield stopper 30 and the shield terminal 40 are coaxially arranged so that the orientation positions are aligned.

Next, as shown by an arrow in FIG. 3A, the shield terminal 40 is brought closer to the shield stopper 30 in the axial direction. In this operation of bringing the shield terminal 40 closer to the shield stopper 30, as shown in FIG. 3B, the protrusion 45 of the hood portion 42 passes through the notch 33 of the flange portion 32, and the hood portion 42 It is continued until the bottom wall portion 43 of the above abuts on the flange portion 32.

Next, as shown by an arrow in FIG. 3C, the shield terminal 40 is rotated in the circumferential direction by a predetermined angle with respect to the shield stopper 30. As a result, the protrusion 45 of the hood portion 42 moves to a position different from that of the notch 33 of the flange portion 32 in the circumferential direction, and as shown in FIGS. 3 (c) and 3 (d), a plurality of locations in the circumferential direction. At (in this example, two places), the outer peripheral edge of the flange portion 32 is sandwiched between the bottom wall portion 43 of the hood portion 42 and the protrusion 45 in the axial direction. As a result, the shield terminal 40 is fixed so as not to be relatively movable in the axial direction with respect to the shield stopper 30.

Next, assembling the grounding member 2 to the shielded electric wire 1 will be described with reference to FIGS. 4 to 6.

First, as shown in FIG. 4A, a shielded electric wire 1 in which the outer circumference of the coated electric wire 10 is covered with a braided conductor 20, a grounding member 2 (specifically, a shield stopper 30, a shield terminal 40, and a shield terminal 40, and Prepare the shield ring 50).

Next, as shown in FIG. 4B, the shield stopper 30 is inserted into the braided conductor 20 of the shielded electric wire 1 from the first main body 31 side, and enters a predetermined distance from the tip of the braided conductor 20 (FIG. 4). (See (c)).

Next, as shown in FIG. 4C, the first main body portion 31 is crimped and fixed to the braided conductor 20 using a predetermined jig. As a result, the shield stopper 30 is fixed so as not to be relatively movable with respect to the braided conductor 20 in a state where the shield stopper 30 presses the braided conductor 20 inward in the radial direction toward the coated electric wire 10. By this pressing, the positional deviation between the braided conductor 20 and the covered electric wire 10 is suppressed. In this example, the first main body 31 is pressure-deformed into a hexagonal cylinder, but the first main body 31 may be pressure-deformed into another shape (square cylinder, etc.). Needless to say.

Next, as shown in FIG. 5A, the shield terminal 40 is inserted into the braided conductor 20 of the shielded electric wire 1 from the hood portion 42 side, and the circumference of the notch 33 of the flange portion 32 and the protrusion 45 of the hood portion 42. With the orientation positions aligned, the shield terminal 40 is brought closer to the shield stopper 30 in the axial direction (see the arrow in FIG. 5A). In the operation of bringing the shield terminal 40 closer to the shield stopper 30 in this way, as described above, the protrusion 45 of the hood portion 42 passes through the notch 33 of the flange portion 32, and the bottom wall portion 43 of the hood portion 42 Continues until it comes into contact with the flange portion 32.

When the bottom wall portion 43 of the hood portion 42 comes into contact with the flange portion 32, as shown in FIG. 5 (b), the shield terminal 40 is rotated in the circumferential direction by a predetermined angle with respect to the shield stopper 30 (FIG. 5 (b). ) Refer to the arrow). As a result, the protrusion 45 of the hood portion 42 moves to a position different from that of the notch 33 of the flange portion 32 in the circumferential direction, so that the outer peripheral edge of the flange portion 32 becomes the bottom of the hood portion 42 in the axial direction as described above. It is sandwiched between the wall portion 43 and the protrusion 45 (see FIGS. 3 (c) and 3 (d)). As a result, the shield terminal 40 is fixed so as not to be relatively movable in the axial direction with respect to the shield stopper 30.

Next, as shown in FIG. 5 (c), the diameter of the end 21 of the braided conductor 20 exposed from the tip of the second main body 41 of the shield terminal 40 to the tip side is increased (arrow in FIG. 5 (c)). As shown in FIG. 6A, the diameter-expanded end portion 21 is moved outward in the radial direction starting from the tip of the second main body portion 41 (in the direction of covering the outer peripheral surface of the second main body portion 41). ) Wrap back. As a result, the end portion 21 of the braided conductor 20 is arranged on the outer peripheral surface of the second main body portion 41 so as to cover the outer peripheral surface of the second main body portion 41.

Next, as shown in FIG. 6B, the shield ring 50 is inserted and arranged on the outer circumference of the end portion 21 of the folded braided conductor 20 (see the arrow in FIG. 6B). As a result, a state in which the folded end portion 21 is sandwiched between the outer peripheral surface of the second main body portion 41 and the inner peripheral surface of the shield ring 50 can be obtained.

Then, as shown in FIG. 6C, the shield ring 50 is crimped and fixed to the end portion 21 (thus, the second main body portion 41) of the braided conductor 20 using a predetermined jig. As a result, the shield ring 50 becomes immovable relative to the shield terminal 40 in a state where the end 21 of the braided conductor 20 is sandwiched between the outer peripheral surface of the second main body 41 and the inner peripheral surface of the shield ring 50. It is fixed. In this example, the shield ring 50 is pressure-deformed into a hexagonal cylinder, but it goes without saying that the shield ring 50 may be pressure-deformed into another shape (square cylinder, etc.).

As described above, the assembly of the grounding member 2 to the shielded electric wire 1 is completed. As a result, the shielded electric wire 1 to which the grounding member 2 shown in FIG. 1 is attached is obtained.

As described above, according to the shielded electric wire 1 to which the grounding member 2 according to the present embodiment is attached, the shield stopper 30 is braided while the shield stopper 30 presses the braided conductor 20 against the coated electric wire 10. It is fixed to the conductor 20 so as to be relatively immovable. By this pressing, the positional deviation between the braided conductor 20 and the covered electric wire 10 is suppressed. Further, the shield terminal 40 is fixed to the shield stopper 30 so as not to be relatively movable, and the end portion 21 of the braided conductor 20 is sandwiched between the shield terminal 40 (second main body portion 41) and the outer peripheral surface. The shield ring 50 is fixed to. As a result, the contact area between the shield terminal 40, the shield ring 50, and the braided conductor 20 can be increased. Therefore, if the grounding member 2 is connected to the grounding object (body frame or the like), the electromagnetic noise collected by the braided conductor 20 can be emitted to the grounding object through the grounding member 2. Further, since the shield stopper 30 is fixed to the braided conductor 20 so as to be relatively immovable, if the shield terminal 40 and the shield ring 50 are attached to the shield electric wire 1 with the shield stopper 30 as a reference, the grounding member 2 is positioned as designed. It can also be installed with high accuracy.

Therefore, according to the shielded electric wire 1 to which the grounding member 2 of the present configuration is attached, the function of fixing the coated electric wire 10 and the braided conductor 20 included in the shielded electric wire 1 and the function of grounding the braided conductor 20 are integrated. Can have Further, since the grounding member 2 can be attached to the position as designed with high accuracy, it is not necessary to unnecessarily increase the grounding jig (grounding connector structure) when grounding the shielded electric wire 1 to the vehicle body frame or the like of an automobile. ..

Further, after fixing the shield stopper 30 to the braided conductor 20, the shield terminal 40 is axially connected to the shield stopper 30 so that the protrusion 45 of the hood portion 42 of the shield terminal 40 passes through the notch 33 of the flange portion 32 of the shield stopper 30. Further, the shield terminal 40 can be rotated in the circumferential direction to fix the shield terminal 40 to the shield stopper 30. As a result, the grounding member 2 can be attached to the position determined by the shield stopper 30 by a simple procedure. Therefore, the workability of the work of attaching the grounding member 2 to the shielded electric wire 1 can be improved.

Further, by fixing the hood portion 42 and the flange portion 32 by the plurality of protrusions 45 provided on the hood portion 42, the shield stopper 30 and the shield terminal 40 can be fixed more stably.
