[0003] Patent Document 1: Japanese Patent Application Laid-Open No. 8-250218 Summary of the invention Problems to be solved by the invention

[0004] When the shielded wire is installed at the connection destination, the end of the metal shell on the opposite side of the portion crimped to the braid is electrically connected to the GND terminal of the connection destination. However, when the metal shell is tightened and fixed to the braid, the tightening stress is transmitted to the end side of the metal shell, so that the end of the metal shell expands radially outward, and as a result, it may be deformed into a trumpet shape. In this case, since the diameter of the end of the metal shell does not become the target shape, it may cause an obstacle to the connection state between the end of the metal shell and the connection destination of the shielded wire.

[0010] First, embodiments of the present invention will be described by way of examples. [1] The shielded electric wire of the present invention is provided with a shielding member for shielding noise on the outer peripheral surface of the electric wire member electrically connected to the other connector via the electric terminal, and has a cylindrical shielding body, the shielding body comprising: a wire crimping portion fixed to the shielding member by crimping; and a shielding connection portion contacting the GND terminal of the other connector when the electric terminal is electrically connected to the other connector, the wire crimping portion having a slit, the slit absorbing deformation of the shielding connection portion when the wire crimping portion is crimped to the shielding member.

[0011] According to the structure of this example, when the wire crimping portion of the shielding body is crimped to the shielding member of the shielded wire, the unnecessary deformation of the shielding body caused by the crimping force can be released into the slit. That is, when the wire crimping portion is crimped, the deformation of the shielding body is absorbed by the slit, so that the deformation is not easily transmitted to other parts of the shielding body. As a result, the shielding connection portion of the shielding body is not easily deformed. Therefore, the shape of the shielding connection portion connected to the GND terminal of the other connector in the shielding body can be maintained in an optimal shape. Therefore, the shielding body can be well connected to the other connector.

[0012] [2] In the above [1], the slit is an inclined slit that intersects the axial direction of the shielding body. According to this structure, for example, when the shielding member is woven, the slit can be arranged at an inclination relative to the weave. Therefore, the slit can bite into the weave during crimping, which helps to improve the crimping force.

[0013] [3] In the above [1] or [2], the slit is one of a plurality of slits, and the plurality of slits are respectively arranged at different positions in the circumferential direction of the shielding body. According to this structure, the shielding body can be deformed evenly when the shielding body is crimped. Therefore, it helps to suppress the deformation of the shielding connection part.

[0014] [4] In any one of [1] to [3] above, the shield connection portion has a leaf spring portion on the outer peripheral surface of the shielding body that contacts the GND terminal. According to this structure, even if the shielding body is fixed to the shielding member by crimping, the position of the leaf spring portion is not easily affected. Therefore, the leaf spring portion can contact the GND terminal with an optimal tension. Therefore, it is further helpful to connect the shielding body to the other connector well.

[0015] [5] In any one of [1] to [4] above, the shield has a folded portion formed by folding back an end of the shield, and the wire crimping portion is crimped to the folded portion. According to this structure, the shield can be crimped and fixed to the folded portion of the shield that can be easily tightened.

[0016] [6] In the above [5], the shielded electric wire has a ring member inside the folded portion, and the ring member and the wire crimping portion sandwich and hold the folded portion. According to this structure, the shield body can be firmly fixed to the shielding member using the ring member as a base.

[0017] [7] In any one of the above [1] to [6], the shielding body has a snap-fitting portion, and when the shielding body is mounted on a connector housing that is engaged with the mating connector, the snap-fitting portion snaps into the connector housing so that the shielding body does not fall off the connector housing. According to this structure, since the shielding body can be held on the connector housing by the snap-fitting portion, the shielding body can be prevented from falling off the connector housing.

[0018] [8] In any one of [1] to [7] above, the shielding body has a positioning portion, and when the shielding body is mounted on a connector housing that is engaged with the mating connector, the positioning portion positions the shielding body in the insertion direction into the connector housing. According to this structure, since the shielding body can be positioned relative to the connector housing in the insertion direction, the shielding body can be arranged in an optimal installation position.

[0019] [9] In any one of [1] to [8] above, the electric terminal has a terminal body and a terminal end fixed to the electric wire member, the counterpart connector terminal of the counterpart connector is connected to the terminal body, the terminal body is exposed to the outside of the shielding body, and the terminal end is accommodated in the inside of the shielding body. According to this structure, the shielding body can be formed into a short shape that only covers the periphery of the end of the electric terminal.

[0020]

[10] The connector of the present invention comprises: a shielded electric wire, wherein a shielding member for shielding noise is provided on the outer peripheral surface of the electric wire member electrically connected to the other connector via the electric terminal; a connector housing installed at the connection destination of the shielded electric wire; and a cap covering the electric terminal, wherein the shielded electric wire comprises a cylindrical shielding body, wherein the shielding body comprises: a wire crimping portion fixed to the shielding member by crimping; and a shielding connection portion contacting the GND terminal of the other connector when the electric terminal is electrically connected to the other connector, wherein the wire crimping portion comprises a slit, wherein the slit absorbs deformation of the shielding connection portion when the wire crimping portion is crimped to the shielding member.

In addition, the present invention is not limited to these examples, but is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In each of the drawings, for the convenience of explanation, a part of the structure is sometimes enlarged or simplified. In addition, the dimensional ratios of each part are sometimes different from the actual ones.

[0022] (Wire Harness 1) like Figure 1 As shown in FIG. 1 , the wiring harness 1 includes a shielded wire 2 and a connector 3 for attaching the shielded wire 2 to a connection destination. The connector 3 includes a connector housing 4, a cap 5 attached to the end of the shielded wire 2, and a cover 6 covering the back of the connector housing 4. The connector housing 4 has a barrel 7 for inserting the shielded wire 2 and a plate-like portion 8 fixed to the connection destination. The plate-like portion 8 is formed by a plurality of ( Figure 1 The stopper 9 (two shown in the figure) is fixed to the connection destination. The stopper 9 is, for example, a bolt.

[0023] In the case of this example, a plurality of shielded electric wires 2 are arranged in a row. In this example, two shielded electric wires 2 are arranged on the + terminal side and the - terminal side. In addition, since both of these shielded electric wires 2 have the same structure, only the shielded electric wire 2 on one side will be described. A cap 5 and a cover 6 are provided on each shielded electric wire 2. The cap 5 is formed into a substantially cylindrical shape, for example. The cover 6 is formed into a shape that holds the shielded electric wire 2 and leads the shielded electric wire 2 out from the back side of the barrel 7 of the connector housing 4, for example. The cover 6 is fixed to the connector housing 4 by a locking structure, for example.

[0024] (Shielded wire 2) like Figure 3 and Figure 4 As shown, the shielded wire 2 comprises: a wire body 13 having a shield 12 for shielding noise; an electric terminal 14 mounted at the end of the wire body 13; and a cylindrical shielding body 15 for connecting the shield 12 to GND. The shielded wire 2 is inserted into the hole 16 of the barrel 7 (see Figure 4 ) and installed in the connector housing 4.

[0025] like Figure 3 As shown, the shielded electric wire 2 (electric wire body 13) includes an electric wire component 21, and the electric wire component 21 includes a core wire 19 and an insulating coating 20. The electric wire component 21 includes, for example, a core wire 19 made of a conductor and an insulating coating 20 covering the outer periphery of the core wire 19. The electric wire component 21 is, for example, a high-voltage electric wire corresponding to a high voltage and a large current.

[0026] The core wire 19 is, for example, a stranded wire formed by twisting a plurality of metal wires, or a single core wire formed by a columnar metal rod having a solid structure inside. The core wire 19 may also be, for example, a combination of a plurality of conductors of a stranded wire or a single core wire. As the material of the core wire 19, for example, a copper-based, aluminum-based, or other metal material is used.

[0027] The insulating coating 20 covers the outer peripheral surface of the core wire 19 all around. The insulating coating 20 is made of an insulating material such as a synthetic resin. As the material of the insulating coating 20, for example, a synthetic resin having a polyolefin resin as a main component, such as cross-linked polyethylene and cross-linked polypropylene, is used. As the material of the insulating coating 20, one material may be used alone, or two or more materials may be used in appropriate combination.

[0028] The shield 12 is, for example, a braid (braided wire) formed by tying thin metal wires into a braided shape. The shield 12 has a folded portion 22 formed by folding the shield 12 at the end of the shield 12. A covering 23 that covers the wire 21 from the periphery is provided on the outer peripheral surface of the shield 12. The covering 23 is, for example, a protective covering portion made of resin.

[0029] (Mating connector 26) like Figure 2 As shown, the connector 3 (connector housing 4) is fitted with a counterpart connector 26 as a connection destination of the wiring harness 1. For example, when the connector 3 is a male connector, the counterpart connector 26 is a female connector. The counterpart connector 26 has a counterpart connector terminal 27 connected to the electrical terminal 14. A GND terminal 28 grounded to GND is provided inside the counterpart connector 26. The GND terminal 28 is, for example, a plate-shaped electrical contact provided on the inner peripheral surface of the counterpart connector 26.

[0030] (Shape of the electrical terminal 14) like Figure 5 As shown, the electric terminal 14 has a terminal body 30 and a terminal end 31 fixed to the electric wire body 13, and the counterpart connector terminal 27 of the counterpart connector 26 is connected to the terminal body 30. The terminal body 30 is exposed to the outside of the shielding body 15. The terminal end 31 is accommodated inside the shielding body 15. In the case of this example, the terminal body 30 of the electric terminal 14 is formed in a cylindrical shape, and the terminal end 31 is formed in a flat plate shape. The electric terminal 14 is accommodated inside the cap 5 when the cap 5 is installed. In this way, the cap 5 covers the electric terminal 14.

[0031] (Sealing structure of connector 3) like Figure 4 and Figure 5 As shown, the connector housing 4 is provided with a first sealing member 33, which seals the gap between the connector housing 4 and the mating connector 26. The first sealing member 33 is, for example, a rubber seal. The first sealing member 33 is, for example, mounted on the outer periphery of the portion of the barrel 7 where the cap 5 is inserted.

[0032] A second seal member 34 is provided between the shielded wire 2 and the connector housing 4 to seal the gap therebetween. The second seal member 34 is, for example, a rubber seal and is disposed between the outer peripheral surface of the shielded wire 2 and the inner peripheral surface of the cylinder 7, for example.

[0033] (Shielding body 15) like Figure 3 to Figure 6 As shown, the shielding body 15 has: an electric wire crimping portion 37 fixed to the shielding member 12 by crimping; and a shield connecting portion 38, which contacts the GND terminal 28 of the other connector 26 when the electric terminal 14 is electrically connected to the other connector 26. The shielding body 15 is formed in a substantially cylindrical shape, for example, and has a hole 15a for passing the end of the electric wire body 13 and the electric terminal 14.

[0034] The shield connection portion 38 has a leaf spring portion 39 that contacts the GND terminal 28 on the outer peripheral surface of the shielding body 15. A plurality of leaf spring portions 39 (four in this example) are provided, and are arranged at equal intervals in the circumferential direction of the shielding body 15. The leaf spring portion 39 is formed in a cantilever shape, for example, and has a circular convex contact that contacts the GND terminal 28. A protrusion 39a that can contact the back of the leaf spring portion 39 is formed on the shielding body 15. The protrusion 39a is formed by cutting a portion of the shielding body 15 and bending the cut portion.

[0035] The shielding body 15 has a snap-fitting portion 40. When the shielding body 15 is mounted on the connector housing 4 that is engaged with the mating connector 26, the snap-fitting portion 40 snaps into the connector housing 4 so that the shielding body 15 does not fall off the connector housing 4. A plurality of (two in this example) snap-fitting portions 40 are provided on the outer peripheral surface of the shielding body 15. A pair of snap-fitting portions 40 are arranged opposite to each other in the diameter direction of the shielding body 15. The snap-fitting portion 40 is formed, for example, into a convex shape having an inclined surface, the inclined surface facing the direction in which the shielding body 15 is inserted into the connector housing 4 ( Figure 3 +X-axis direction shown) decreases.

[0036] The shielding body 15 has a positioning portion 41. When the shielding body 15 is mounted on the connector housing 4 that is engaged with the mating connector 26, the positioning portion 41 is aligned in the insertion direction ( Figure 3 The shielding body 15 is positioned in the +X axis direction shown in the figure. A plurality of positioning portions 41 (two in this example) are provided on the outer peripheral surface of the shielding body 15. A pair of positioning portions 41 are arranged opposite to each other in the diameter direction of the shielding body 15. The positioning portions 41 are formed, for example, into a convex shape having an inclined surface, and the inclined surface faces the direction of inserting the shielding body 15 into the connector housing 4 ( Figure 3 +X-axis direction shown).

[0037] like Figure 7As shown, a plurality of leaf spring portions 39 are arranged at intervals of 90 degrees in the circumferential direction of the shielding body 15. The engaging portion 40 is arranged at a position offset by 45 degrees in the circumferential direction relative to the leaf spring portion 39 located next to the shielding body 15 in the circumferential direction. The positioning portion 41 is arranged at a position offset by 45 degrees in the circumferential direction relative to the leaf spring portion 39 located next to the shielding body 15 in the circumferential direction. The engaging portion 40 and the positioning portion 41 are alternately arranged at intervals of 90 degrees in the circumferential direction of the shielding body 15.

[0038] like Figure 8 As shown, a convex portion 43 is formed on the connector housing 4 to engage with the engaging portion 40 of the shielding body 15. The convex portion 43 is formed, for example, on the inner peripheral surface of the hole 16 of the barrel 7. The engaging portion 40 engages with the convex portion 43, thereby preventing the shielding body 15 from falling off the connector housing 4. A convex portion 44 is formed on the connector housing 4 to engage with the positioning portion 41 of the shielding body 15. The convex portion 44 is formed, for example, on the inner peripheral surface of the hole 16 of the barrel 7. The positioning portion 41 contacts the convex portion 44, thereby setting the position of the shielding body 15 when inserted into the connector housing 4.

[0039] (Crimp structure using slit 46) like Figure 3 to Figure 7 As shown in FIG. 1 , the wire crimping portion 37 has a plurality of slits 46, and the plurality of slits 46 absorb deformation of the shield connection portion 38 when the wire crimping portion 37 is crimped to the shield 12. In this example, the shield 15 is fixed to the shield 12 by crimping the wire crimping portion 37 to the shield 12 by tightening or the like. The slits 46 are axially aligned with the shield 15 ( Figure 3 The slits 46 are formed at different positions in the circumferential direction of the shielding body 15. The wire crimping portion 37 is crimped to the folded portion 22.

[0040] like Figure 3 and Figure 5 As shown, the shielded electric wire 2 is provided with a ring member 47, which becomes a base when the shielding body 15 is crimped to the shielding member 12. The ring member 47 is made of metal, for example. A flange 48 (at the base end) that hooks onto the end of the covering member 23 is formed at the base end of the ring member 47. Figure 5 The ring member 47 is disposed on the inner side of the folded-back portion 22 on the outer peripheral surface of the covering member 23 of the shield member 12 , and sandwiches and holds the folded-back portion 22 together with the wire crimping portion 37 .

[0041] (Function of Cap 5) like Fig. 9As shown, the cap 5 includes a cap body 50 for housing the electric terminal 14 of the shielded electric wire 2 and an outer peripheral wall 51 arranged at a predetermined interval relative to the cap body 50. The cap body 50 is formed in a cylindrical shape, for example. The outer peripheral wall 51 is formed in a circumferential shape around the cap body 50. When the shielding body 15 is mounted on the connector housing 4, it is inserted into a gap 52 between the cap body 50 and the outer peripheral wall 51.

[0042] like Figure 5 As shown, a hole 53 is formed on the outer peripheral wall 51 of the cap 5 so that the leaf spring portion 39 of the installed shielding body 15 is exposed to the outside. A protrusion 54 for engaging with the shielding body 15 is formed on the outer peripheral surface of the cap body 50. A recess 55 engaging with the protrusion 54 is formed in the shielding body 15. The recess 55 is, for example, a through hole. The cap body 50 is arranged between the electrical terminal 14 and the shielding body 15 when the cap 5 is installed on the shielding body 15, so as to insulate these.

[0043] (Effects of Implementation Methods) Next, the operation of the connector 3 according to the present embodiment will be described. like Fig.10 and Fig.11 As shown, first, the shielding body 15 is fixed to the wire body 13 by crimping. In this example, the surrounding of the wire crimping portion 37 (including the slit 46) is clamped by a mold ( Fig.10 and Fig.11 The crimping area Ea) shown by the dotted line portion is compressed to crimp the wire crimping portion 37. The crimping of the wire crimping portion 37 is performed by, for example, a compression process, and a press die is used for the compression process.

[0044] like Fig.12 As shown, when the wire crimping portion 37 is crimped, the wire crimping portion 37 is tightened by its crimping force, so that the wire crimping portion 37 is deformed in a concave manner. At this time, the unnecessary deformation of the shielding body 15 caused by the crimping force is released into the slit 46. In this way, when the wire crimping portion 37 is crimped, the deformation of the shielding body 15 is absorbed by the slit 46, so that the deformation is not easily transmitted to other parts of the shielding body 15. As a result, the shielding connection portion 38 of the shielding body 15 is not easily deformed. Therefore, the shape of the shielding connection portion 38 can be maintained in an optimal shape. Therefore, the shielding body 15 can be well connected to the other connector 26.

[0045] After the shielding body 15 is mounted on the wire body 13 to produce the shielding wire 2, the shielding wire 2 is mounted on the connector housing 4. Specifically, the shielding wire 2 is inserted into the hole 16 of the connector housing 4. The insertion is performed until the positioning portion 41 abuts against the convex portion 44 of the connector housing 4. In addition, when the shielding wire 2 is inserted deep into the hole 16, the engaging portion 40 is hooked on the convex portion 43 to prevent it from falling out. Thus, the shielding body 15, that is, the shielding wire 2 is fixed to the connector housing 4.

[0046] Next, the cap 5 is mounted on the shielded wire 2 mounted on the connector housing 4. At this time, the cap 5 is mounted on the shielded wire 2 in such a manner that the shielding body 15 is inserted into the gap 52. The insertion is performed until the leaf spring portion 39 of the shielding body 15 is located in the hole 53 of the cap 5 and the protrusion 54 of the cap 5 is engaged with the recess 55 of the shielding body 15. As described above, the connector 3 is assembled.

[0047] (Effects of Embodiments) According to the connector 3 of the above-described embodiment, the following effects can be obtained. (1) The shielded electric wire 2 is provided with a shield 12 for shielding noise on the outer peripheral surface of the electric wire 21 electrically connected to the other connector 26 via the electric terminal 14. The shielded electric wire 2 has a cylindrical shielding body 15. The shielding body 15 has: a wire crimping portion 37 fixed to the shield 12 by crimping; and a shield connection portion 38 contacting the GND terminal 28 of the other connector 26 when the electric terminal 14 is electrically connected to the other connector 26. The wire crimping portion 37 has a slit 46, and the slit 46 absorbs the deformation of the shield connection portion 38 when the wire crimping portion 37 is crimped to the shield 12.

[0048] According to the structure of this example, when the wire crimping portion 37 of the shielding body 15 is crimped to the shielding member 12 of the shielded wire 2, the unnecessary deformation of the shielding body 15 caused by the crimping force can be released into the slit 46. That is, when the wire crimping portion 37 is crimped, the deformation of the shielding body 15 is absorbed by the slit 46, so that the deformation is not easily transmitted to other parts of the shielding body 15. As a result, the shielding connection portion 38 of the shielding body 15 is not easily deformed. Therefore, the shape of the shielding connection portion 38 connected to the GND terminal 28 of the other connector 26 in the shielding body 15 can be maintained in an optimal shape. Therefore, the shielding body 15 and the other connector 26 can be well connected.

[0049] (2) The slit 46 is an inclined slit that intersects the axial direction of the shield body 15. With this configuration, for example, when the shield 12 is braided, the slit 46 can be arranged obliquely relative to the braid. Therefore, the slit 46 can bite into the braid during crimping, which helps improve the crimping force.

[0050] (3) The plurality of slits 46 are formed at different positions in the circumferential direction of the shield body 15. This configuration allows the shield body 15 to be deformed evenly during crimping of the shield body 15. This helps suppress deformation of the shield connection portion 38.

[0051] (4) The shield connection portion 38 has a leaf spring portion 39 that contacts the GND terminal 28 on the outer peripheral surface of the shield body 15. According to this structure, even if the shield body 15 is fixed to the shield member 12 by crimping, the position of the leaf spring portion 39 is not easily affected. Therefore, the leaf spring portion 39 can be brought into contact with the GND terminal 28 with an optimal tension. Therefore, it is further helpful to connect the shield body 15 and the counterpart connector 26 well.

[0052] (5) The shield 12 has the folded portion 22 formed by folding back the end of the shield 12. The wire crimping portion 37 of the shield 15 is crimped to the folded portion 22 of the shield 12. With this configuration, the shield 15 can be crimped and fixed to the folded portion 22 of the shield 12, which can be easily tightened.

[0053] (6) The shielded electric wire 2 includes the ring member 47 disposed inside the folded portion 22. The ring member 47 sandwiches and holds the folded portion 22 together with the wire crimping portion 37. With this configuration, the shield body 15 can be firmly fixed to the shield 12 using the ring member 47 as a base.

[0054] (7) The shielding body 15 has a snap-fitting portion 40, and when the shielding body 15 is mounted on the connector housing 4 engaged with the mating connector 26, the snap-fitting portion 40 snaps into the connector housing 4 so that the shielding body 15 does not fall off the connector housing 4. According to this structure, since the shielding body 15 can be held on the connector housing 4 by the snap-fitting portion 40, the shielding body 15 can be prevented from falling off the connector housing 4.

[0055] (8) The shield body 15 has a positioning portion 41, and when the shield body 15 is mounted on the connector housing 4 that is engaged with the mating connector 26, the positioning portion 41 positions the shield body 15 in the insertion direction into the connector housing 4. According to this structure, since the shield body 15 can be positioned in the insertion direction relative to the connector housing 4, the shield body 15 can be arranged in the optimal installation position.

[0056] (9) The electric terminal 14 includes a terminal body 30 and a terminal end 31 fixed to the electric wire member 21, and the mating connector terminal 27 of the mating connector 26 is connected to the terminal body 30. The terminal body 30 is exposed to the outside of the shielding body 15. The terminal end 31 is accommodated in the inside of the shielding body 15. According to this structure, the shielding body 15 can be formed into a short shape that covers only the periphery of the end of the electric terminal 14.

[0057] (Other embodiments) In addition, this embodiment can be implemented as the following modifications. This embodiment and the following modifications can be implemented in combination with each other within the range that there is no technical contradiction.

[0058] The shield 12 is not limited to braiding, and other members such as a tube member (tube shield) may be used. The slit 46 is not limited to an elongated hole, and may be, for example, a polygonal hole or a circular (elliptical) hole. In addition, the slit 46 may be, for example, a hole having a design shape, or may be a mark, a symbol, or a predetermined geometric shape.

[0059] The slit 46 may be a combination of different slit shapes. The shielding body 15 may also have only one slit 46 . The electrical terminal 14 may also be entirely located inside the shielding body 15 .
