FIG. 3 is a schematic cross-sectional view of the shielded cable 10 with a connector connected to the electronic unit 12. FIG. 4 is a schematic perspective view showing the shielded cable with connector 10 in an exploded manner.

  The shielded cable 10 with a connector according to the present invention can be fixed to a wall 16a as a connection target having a plurality of insertion holes 24, as shown in FIGS. The shielded cable 10 with a connector includes a plurality of flexible wires 30, a connection terminal 60 fixed to each end of the wire 30, and a plurality of wires 30 at positions separated from the connection terminals 60. The electric wire holder 52 that holds the gap between them and the portion of the electric wire 30 between the connection terminal 60 and the electric wire holder 52 are fitted so as to be relatively displaceable with respect to the electric wire holder 52. And a waterproof plug 64 that plugs between the inner peripheral surface of the insertion hole.

  In the first embodiment, the shielded cable 10 with a connector is directed to the side opposite to the connection terminal 60 and the shield case 38 that has a plurality of electric wires 30 inserted therein and can be fixed to the wall 16a and has conductivity. A conductive shield braid 36 that covers the portion of the electric wire 30 extending from the shield case 38 and is connected to the shield case 38 is further provided.

The electronic unit 12 is, for example, a control unit for an electric motor mounted on a vehicle, and the shielded cable 10 with a connector supplies power to the electronic unit 12 with a three-phase alternating current.
The electronic unit 12 includes a metal housing 14, and the housing 14 includes, for example, a box-shaped case 16 having an opening and a lid 18 that closes the opening of the case 16. A substrate 22 having electrode terminals 20 is installed in the housing 14.

  The case 16 has a wall 16a to which the shielded cable with connector 10 is fixed. The wall 16a has three insertion holes 24 at predetermined positions. Specifically, the insertion holes 24 are arranged in a line at regular intervals. In addition, two screw holes 26 are provided in the wall 16a so as to sandwich, for example, three insertion holes 24 therebetween.

  As shown in FIGS. 3 and 4, the shielded cable 10 with the connector has three electric wires 30, and each electric wire 30 covers a core wire (metal wire) 32 made of a metal such as copper and the core wire 32. It consists of an electrically insulating sheath (outer skin) 34. The outer diameter of the electric wire 30 is 8 mm or more and 40 mm or less, for example. In the present embodiment, the outer diameter of the electric wire 30 is 20 mm.

  The three electric wires 30 are covered with a metal shield braid 36 except for a region at a predetermined distance from the tip. The tip of the shield braid 36 is fixed to a metal shield case 38. The shield case 38 has a cylindrical portion 40 through which the electric wire 30 is inserted, and an end portion of the shield braid 36 is fixed to the outer surface of the cylindrical portion 40 by a metal band 42.

  An outward flange 44 is integrally connected to one end of the cylindrical portion 40, and the outward flange 44 is fixed to the wall 16 a of the case 16 using a screw 48 shown in FIG. 2. In addition, an inward flange 50 is integrally connected to the other end of the cylindrical portion 40.

  An electric wire holder 52 is housed inside the cylindrical portion 40 of the shield case 38. The electric wire holder 52 is press-fitted into the shield case 38 and is prevented from coming off from the tube portion 40 by the inward flange portion 50.

  The electric wire holder 52 is made of, for example, resin and includes two halves 54. The halves 54 constitute the electric wire holder 52 by being fixed to each other using, for example, screws 56. Each of the halves 54 has a rectangular parallelepiped shape and has contact surfaces that are brought into contact with each other. Three holding grooves 58 are formed on the contact surface in parallel with each other with a predetermined interval. The interval between the holding grooves 58 is set so as to correspond to the interval between the insertion holes 24.

  Each holding groove 58 has a semicircular cross-sectional shape, and when the half body 54 is brought into contact with each other, the electric wire 30 is clamped by the wall surface of the holding groove 58. That is, the two holding grooves 58 constitute a hole through which the electric wire 30 is inserted so as not to be relatively displaced.

  At the tip of the electric wire 30, the sheath 34 is peeled off to expose the end of the core wire 32, and the metal connection terminal 60 is fixed to the end of the core wire 32. In a state where the shielded cable with connector 10 is connected to the electronic unit 12, the electric wire 30 extends through the insertion hole 24, and the connection terminal 60 is disposed in the housing 14. The connection terminal 60 is fixed to the electrode terminal 20 of the electronic unit 12 using screws 62.

  A waterproof plug 64 is attached to the portion of the electric wire 30 that extends between the connection terminal 60 and the electric wire holder 52. The waterproof plug 64 has a rotationally symmetric shape having a through hole at the center, and the electric wire 30 is inserted into the through hole of the waterproof plug 64.

  That is, the waterproof plug 64 is fitted to the wire holder 52 so as to be relatively displaceable when the shielded cable with connector 10 is not connected to the electronic unit 12. On the other hand, in the state where the shielded cable with connector 10 is connected to the electronic unit 12, most of the waterproof plug 64 is inserted into the insertion hole 24, and the outer peripheral surface of the electric wire 30 and the inner peripheral surface of the insertion hole 24. Seal between.

FIG. 5 is a view schematically showing a part of a side surface and a cross section of the waterproof plug 64.
Specifically, the waterproof plug 64 includes a cylindrical portion 66 that is inserted into the insertion hole 24, and an outward flange portion 68 that is integrally connected to the proximal end portion 66 k of the cylindrical portion 66.
The outward flange 68 restricts the amount of the waterproof plug 64 that enters the insertion hole 24 by contacting the wall 16a so that the waterproof plug 64 does not come out of the insertion hole 24 into the housing 14. That is, the outward flange 68 has a function of retaining the cylindrical portion 66 of the waterproof plug 64 in the insertion hole 24. The outward flange 68 can be omitted as appropriate.

  On the other hand, on the outer peripheral surface and the inner peripheral surface of the intermediate portion 66c of the cylindrical portion 66, an annular outward protrusion 70 and an inward protrusion 72 are formed, respectively, and the outward protrusion 70 and the inward protrusion 72 are It closely adheres to the inner peripheral surface of the insertion hole 24 and the outer peripheral surface of the electric wire 30.

Here, the waterproof plug 64 is made of a plurality of materials. Specifically, the distal end portion 74 and the proximal end portion 76 of the waterproof plug 64 are made of a material having a different elasticity from that of the intermediate portion 78.
In the present embodiment, the distal end portion 74 of the waterproof plug 64 is the distal end portion 66 s of the cylindrical portion 66, and the intermediate portion 78 of the waterproof plug 64 is the intermediate portion 66 c of the cylindrical portion 66. The proximal end portion 76 is the proximal end portion 66 k of the cylindrical portion 66 and the outward flange portion 68. The distal end portion 66c of the tubular portion 66 is located on the connection terminal 60 side, the proximal end portion 66k of the tubular portion 66 is located on the wire holder 52 side, and the intermediate portion 66c of the tubular portion 66 is based on the distal end portion 66c. Located between the ends 66k.

  The distal end portion 74 and the proximal end portion 76 of the waterproof plug 64 are harder than the intermediate portion 78 of the waterproof plug 64. That is, the distal end portion 66s and the proximal end portion 66k of the cylindrical portion 66 are harder than the intermediate portion 66c of the cylindrical portion 66. In other words, the intermediate portion 78 of the waterproof plug 64 is softer than the distal end portion 74 and the proximal end portion 76 of the waterproof plug 64.

  The distal end portion 74 and the proximal end portion 76 of the waterproof plug 64 are, for example, PS (polystyrene), PP (polypropylene), PVC (vinyl chloride), PET (polyethylene terephthalate), PU (polyurethane), PA (polyamide), and , PBT (polybutylene terephthalate) and the like, and a kind selected from the group consisting of metals such as copper, aluminum, magnesium, and iron.

The intermediate portion 78 of the waterproof plug 64 is made of, for example, an elastic body selected from the group consisting of a styrene elastomer, an olefin elastomer, a vinyl chloride elastomer, a polyester elastomer, a polyurethane elastomer, a nylon elastomer, and the like.
The waterproof plug 64 can be manufactured by molding.
In addition, the outer peripheral surface of the front-end | tip part 74 of the waterproof plug 64 is formed as the male taper surface 80 as a preferable aspect.

<How to assemble shielded cable with connector>
Hereinafter, an example of the assembly method of the shielded cable with connector 10 described above will be described with reference to FIG.
First, a material cable is prepared as a raw material. The material cable is composed of three electric wires 30 and a shield braid 36 that collectively covers these electric wires 30.
The shield braid 36 is peeled off at the end of the prepared material cable, and the tip of the electric wire 30 is exposed at a predetermined length. Then, a waterproof plug 64 is attached to the tip of the electric wire 30. The waterproof plug 64 is attached to the electric wire 30 by inserting the electric wire 30 through the through hole of the waterproof plug 64.

  Thereafter, the sheath 34 at the distal end portion of the electric wire 30 is peeled off to expose the end portion of the core wire 32. Then, as shown in FIG. 6A, the connection terminal 60 is fixed to the end of the core wire 32 by caulking.

  Next, as shown in FIG. 6B, the three electric wires 30 to which the connection terminal 60 and the waterproof plug 64 are attached are passed through the shield case 38, and the end of the shield braid 36 is covered with the shield case 38. Then, as shown in FIG. 6C, the shield braid 36 is fixed to the shield case 38 by tightening with the metal band 42.

On the other hand, as shown in FIG. 6C, the wire holder 52 is placed at a position separated from the connection terminal 60 by a predetermined length with respect to the wire 30 and at a position closer to the connection terminal 60 than the shield case 38. Install. The portion of the electric wire 30 that is sandwiched between the halves 54 constituting the electric wire holder 52 is disposed in the holding groove 58. At this time, the interval between the electric wires 30 is defined by the interval between the holding grooves 58.
Then, as shown in FIG. 6 (d), the shielded cable with connector 10 is assembled by press-fitting the wire holder 52 into the shield case 38.

<Connecting shielded cable with connector>
Hereinafter, a method of connecting the shielded cable with connector 10 to the electronic unit 12 will be described with reference to FIG. As shown in FIG. 7A, there is a “deviation” between the interval between the insertion holes 24 in the housing 14 of the electronic unit 12 and the interval between the electric wires 30 defined by the electric wire holder 52. To do. That is, it is assumed that there is a deviation between the axis of the insertion hole 24 and the axis of the electric wire 30 or the axis of the waterproof plug 64. Such “deviation” is caused by the processing accuracy of the insertion hole 24 and the electric wire holder 52.

  First, the periphery of the shield case 38 of the shielded cable 10 with connector 10 is gripped, and the shield case 38 is moved toward the wall 16 a of the case 16 so that the connection terminal 60 is inserted into the insertion hole 24. At this time, as shown in FIG. 7B, as the connection terminal 60 advances through the insertion hole 24, the wire 30 extending toward the connection terminal 60 from the wire holder 52 due to “displacement”. A part (extension part) bends based on own flexibility.

  When the shield case 38 comes closer to the wall 16a, the tip of the waterproof plug 64 reaches the opening of the insertion hole 24 as shown in FIG. Thereafter, since the waterproof plug 64 is inserted into the insertion hole 24 with compressive deformation in the radial direction, a larger force is required in the axial direction of the insertion hole 24 in order to push the waterproof plug 64. .

  For this reason, when the shield case 38 comes closer to the wall 16a, the wire holder 52 in the shield case 38 contacts the waterproof plug 64 near the entrance of the insertion hole 24 as shown in FIG. Approach until touching.

When the shield case 38 further approaches the wall 16a in a state where the electric wire holder 52 is in contact with the waterproof plug 64, the waterproof plug 64 finally becomes an outward flange as shown in FIG. It enters into the insertion hole 24 until 44 reaches the wall 16a. In this state, the outward flange portion 44 of the shield case 38 is fixed to the wall 16 a using the screw 48.
Then, when the connection terminal 60 is fixed to the electrode terminal 20 using the screw 62 and the opening of the case 16 is closed with the lid 18, the connection of the shielded cable 10 with the connector to the electronic unit 12 is completed.

In the shielded cable with connector 10 of the first embodiment described above, the waterproof plug 64 is not sandwiched between the electric wire holders 52. That is, the waterproof plug 64 is freely slidable at the extending portion of the electric wire 30.
For this reason, even if there is a “deviation” between the interval between the insertion holes 24 and the interval between the electric wires 30 or the interval between the axes of the waterproof plugs 64, the electric wires 30 are deformed due to flexibility, and as the electric wires are deformed. The waterproof plug 64 is guided and attached to the insertion hole 24. Therefore, even if the position of the waterproof plug 64 before mounting is shifted with respect to the position of the insertion hole 24 formed in the connection target, the waterproof plug 64 is smoothly inserted into the insertion hole 24 and the wall. Biting between 16a and the wire holder 52 is prevented. As a result, the waterproof plug 64 is prevented from being damaged, and the reduction of the waterproof function can be reduced.

  Further, in the shielded cable with connector 10 of the first embodiment described above, the base end portion 76 of the waterproof plug 64 is made of a harder material than the intermediate portion 78, so that the interval between the insertion holes 24 and the interval between the electric wires 30 are Even if there is a “displacement” between them, the center line of the electric wire 30 is aligned with the center line of the insertion hole 24 in the insertion hole 24, and further reduction of the waterproof function can be reduced.

  Here, FIG. 8 is a diagram schematically showing a cross section of the shielded cable 10 with a connector attached to the wall 16a in order to explain the function of the waterproof plug 64. As shown in FIG. As exaggeratedly drawn in the area A surrounded by the one-dot chain line in FIG. 8, the bending of the electric wire 30 due to “displacement” is more difficult than the waterproof plug 64 because the base end portion 76 of the waterproof plug 64 is hard. Are also concentrated on the wire holder 52 side. In other words, the base end portion 76 of the waterproof plug 64 has sufficient hardness to deform the electric wire 30.

  For this reason, in the insertion hole 24, it is suppressed that the waterproof plug 64 is compressed and deformed in a distorted state, and the waterproof plug 64 has an entire circumference between the outer peripheral surface of the electric wire 30 and the inner peripheral surface of the insertion hole 24. Seal evenly and reliably over. For this reason, the waterproof plug 64 exhibits an excellent waterproof function.

  In addition, in the shielded cable with connector 10 according to the first embodiment described above, the distal end portion 74 of the waterproof plug 64 is also made of a hard material, so that the attitude of the electric wire 30 is regulated in a substantially linear shape in the insertion hole 24. The bending of the electric wire 30 in the insertion hole 24 is further prevented. For this reason, distortion of the waterproof plug 64 in the insertion hole 24 is further suppressed, and the sealing performance is further improved.

  Further, in the shielded cable with connector 10 according to the first embodiment described above, the outer peripheral surface of the distal end portion 74 of the waterproof plug 64 is formed as the male tapered surface 80. The plug 64 surely enters the insertion hole 24.

  On the other hand, in the shielded cable 10 with a connector according to the first embodiment described above, the waterproof plug 64 is not sandwiched between the electric wire holders 52, and the waterproof plug 64 is attached to the electric wire holder 52 when the electric wire holder 52 is assembled. There is no need to align. For this reason, this shielded cable 10 with a connector is easy to assemble and can be mass-produced at low cost.

[Second Embodiment]
Hereinafter, a second embodiment will be described. In the following description of the embodiments, the same or similar configurations as those of the preceding embodiments are denoted by the same names or reference numerals and description thereof is omitted.

FIG. 9 is a diagram illustrating a schematic side surface and a part of a cross section of the waterproof plug 90 applied to the shielded cable with a connector according to the second embodiment.
The waterproof plug 90 includes a cylindrical portion 92 and an outward flange portion 68, the distal end portion 94 of the waterproof plug 90 is configured by the distal end portion 92 s of the cylindrical portion 92, and the intermediate portion 78 of the waterproof plug 90 is the intermediate portion 78 of the cylindrical portion 92. The base end portion 66k of the waterproof plug 90 is configured by the base end portion 66k of the cylindrical portion 92 and the outward flange portion 68.

The distal end portion 94 of the waterproof plug 90, that is, the distal end portion 92 s of the cylindrical portion 92 is formed integrally with the intermediate portion 78 of the waterproof plug 90, that is, the intermediate portion 66 c of the cylindrical portion 92, and is softer than the base end portion 76 of the waterproof plug 90. Consists of. That is, the waterproof plug only needs to have a base end portion that is hard at least with respect to the intermediate portion. In other words, it is only necessary that the base end portion of the cylindrical portion is hard at least with respect to the intermediate portion.
In addition, in order to ensure hardness, the base end part of a waterproof plug may contain the metal material, and may consist only of a metal material. When the base of the waterproof plug is made of only a metal material, an O-ring may be used in combination in order to ensure sealing performance.

[Third Embodiment]
Hereinafter, the third embodiment will be described.
FIG. 10 is a view schematically showing a cross section of the shielded cable with connector 100 according to the third embodiment in a state of being attached to the wall 16a, and FIG. 11 is an electric wire holder 101 used in the shielded cable with connector 100. It is a top view which shows roughly the half body 102 of this.

  As shown in FIGS. 11 and 12, the halved body 102 has an enlarged diameter portion 104 having an enlarged inner diameter in the vicinity of the opening of the holding groove 58 so as to allow the electric wire 30 to be bent. For this reason, even if the “displacement” is large and the bending of the electric wire 30 is large, the electric wire holder 101 can be brought closer to the wall 16a.

  Further, the halved body 102 of the electric wire holder 101 is also formed with a concave portion 106 for accommodating the outward flange portion 68 of the waterproof plug 64 on the end face facing the wall 16a. When the outward flange portion 68 of the waterproof plug 64 is accommodated in the concave portion 106 of the half body 102, the electric wire holder 101 is brought into contact with the wall 16a. That is, there is no gap between the wire holder 101 and the wall 16a.

[Fourth Embodiment]
The fourth embodiment will be described below.
FIG. 12 is a plan view showing the connection terminal 110 applied to the shielded cable with connector according to the fourth embodiment, together with the electric wire 30 and the waterproof plug 64. For example, a hook-shaped protrusion 112 that protrudes outward in the radial direction of the electric wire 30 is integrally formed on the connection terminal 110. The protrusion 112 of the connection terminal 110 prevents the waterproof plug 64 from being detached from the electric wire 30 when the electric wire 30 is pulled.

[Fifth Embodiment]
Hereinafter, a fifth embodiment will be described.
FIG. 13 is a schematic cross-sectional view showing a state where the shielded cable with connector 120 of the fifth embodiment is attached to the electronic unit 12, and FIG. 14 is a connection frame 122 used for the shielded cable with connector 120. It is a top view which shows roughly.

  The shielded cable 120 with a connector does not have the shield case 38, but instead has a metal connecting frame 122 having a flat frame shape. The connection frame 122 can be fixed to the wall 16 a using the screw 48, similarly to the outward flange portion 44 of the shield case 38.

The connection frame 122 is provided with a set screw insertion hole 124, and the electric wire holder 52 is formed with a screw hole 126 at a position corresponding to the set screw insertion hole 124. The connection frame 122 is also fixed to the electric wire holder 52 by a set screw 128 screwed into the screw hole 126 through the set screw insertion hole 124. That is, the electric wire holder 52 is fixed to the wall 16a via the connection frame 122.
On the other hand, the end of the shield braid 38 is connected to the outer surface of the connecting frame 122 by, for example, a conductive adhesive or welding.

The present invention is not limited to the first to fifth embodiments described above, and includes forms in which the first to fifth embodiments are appropriately combined and forms obtained by changing these forms.
For example, although the shielded cable with connector 10 according to the first embodiment described above includes the three electric wires 30, it is only necessary to include two or more electric wires 30.

  In the first embodiment, the electric wire 30 is a non-shielded electric wire that does not include a shield layer, but a shielded electric wire that includes a shield layer may be used as the electric wire 30. In this case, the shield case 38 can be omitted.

  Finally, the shielded cable with a connector of the present invention is suitable for a vehicle, but it is needless to say that the shielded cable with a connector can also be applied to devices other than the vehicle.
