[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. The crimping structure of the electric wire and the outer conductor of the present disclosure includes: (1) The crimping portion is provided on an outer conductor connected to an end of an electric wire and is crimped to the outer periphery of the electric wire. The crimping portion has a base portion, a plurality of extensions, and a plurality of claws. The base portion is arranged so as to surround the outer periphery of the electric wire. The extensions are arranged in a line in the circumferential direction of the electric wire, extending in a cantilever shape from the rear edge of the base portion toward the rear in the axial direction of the electric wire. The claws are formed by bending the rear end of each extension inward in the radial direction of the electric wire and bite into the outer surface of the electric wire. Between the claws adjacent in the circumferential direction, the side edges of the claws that extend along the radial direction and face each other are offset in the axial direction. According to this configuration, between the claws adjacent in the circumferential direction, the side edges of the claws that face each other in the circumferential direction are offset in the axial direction, so that interference between adjacent claws can be avoided without narrowing the protruding ends of the claws. This allows the tips of the wide claws to bite into the outer surface of the electric wire, thereby firmly fixing the outer conductor and the electric wire.

[0010] (2) It is preferable that the claws are bent along the circumferential creases, and that the creases of the extending portions adjacent in the circumferential direction are arranged to be shifted in the axial direction. With this configuration, the simple configuration of shifting the creases of the adjacent extending portions in the axial direction can prevent interference between adjacent claws, and thus the tips of the claws can be inserted into the outer surface of the electric wire without narrowing them.

[0011] (3) In (2), a through hole penetrating in the radial direction is formed in the rear edge of the base plate, and the region of the rear edge of the base plate where the through hole is formed protrudes rearward. The extension portion has a first extension portion and a second extension portion adjacent to each other in the circumferential direction. In the axial direction, the dimension of the first extension portion is larger than the dimension of the second extension portion. It is preferable that the first extension portion is disposed in the region of the rear edge of the base plate where the through hole is formed, and the second extension portion is disposed in the region of the rear edge of the base plate where the through hole is not formed. According to this configuration, the position where the first extension portion, which has a larger axial dimension, extends from the rear edge of the base plate is set rearward from the position where the second extension portion, which has a smaller axial dimension, extends, so that the claw portion of the first extension portion and the claw portion of the second extension portion can be prevented from interfering with each other.

[0012] (4) In (1), it is preferable that the claws are bent along creases that are oblique to both the axial and circumferential directions, and that the positions of adjacent creases in the circumferential direction are aligned in the axial direction. With this configuration, the axial positions of adjacent creases in the circumferential direction are aligned, so that interference between adjacent claws can be avoided and the appearance can be improved.

[0013] [Details of the embodiment of the present disclosure] [Embodiment 1] A first embodiment of the present disclosure will be described with reference to Figures 1 to 5. In the figures, the "front side" and the "rear side" are represented by "F" and "B", respectively.

[0014] The crimping structure of the electric wire and the outer conductor in the first embodiment is applied to a shielded conductive path 100. As shown in Figs. 1 and 2, the shielded conductive path 100 includes a shielded electric wire 10, a sleeve 18 fitted onto the shielded electric wire 10, which is an electric wire, a shield terminal 20 connected to the front end of the shielded electric wire 10, and an outer conductor 16 connected to the tip end of the shielded electric wire 10.

[0015] The shielded electric wire 10 is disposed with its axis oriented in the front-rear direction. In the following description, the front-rear direction and the axial direction are used synonymously. The shielded electric wire 10 has a core wire 11 surrounded by an insulating coating 12, a cylindrical shield layer 13 superimposed on the outer periphery of the insulating coating 12, and the outer periphery of the shield layer 13 surrounded by a sheath 14. The shield layer 13 is made of a braided wire. As shown in FIG. 2, at the front end of the shielded electric wire 10, the sheath 14 and the insulating coating 12 are removed, and the core wire 11 is exposed in front of the insulating coating 12. Behind the exposed core wire 11, the sheath 14 is removed, and the shield layer 13 is exposed.

[0016] A sleeve 18 is fitted onto the outer peripheral surface of the shield layer 13 exposed when the sheath 14 is removed. The sleeve 18 is cylindrical. The sleeve 18 surrounds the shield layer 13 and the insulating coating 12. The front end of the shield layer 13 is folded back to cover the outer periphery of the sleeve 18. The area of ​​the shield layer 13 surrounding the sleeve 18 is defined as the folded back portion 15. The front end of the sleeve 18 is located slightly rearward of the front end of the insulating coating 12. The rear end of the sleeve 18 is located forward of the front end of the sheath 14. The front end of the sheath 14 and the rear end of the sleeve 18 are spaced apart in the axial direction.

[0017] The shield terminal 20 includes an inner conductor 21 connected to the front end of the core wire 11, and a dielectric 22 that houses the inner conductor 21. The inner conductor 21 is crimped to the front end of the core wire 11. The inner conductor 21 and the dielectric 22 are housed in the outer conductor 16, which will be described later.

[0018] The outer conductor 16 includes a crimping portion 25. The crimping portion 25 is a portion for fixing the outer conductor 16 to the outer peripheral surface of the shielded electric wire 10 by being crimped to the outer periphery of the shielded electric wire 10. By crimping the crimping portion 25 to the shielded electric wire 10, the front end of the shielded electric wire 10 and the rear end of the shield terminal 20 are connected in a state in which separation in the axial direction is restricted, and the outer conductor 16 and the shield layer 13 are connected in a conductive manner. The crimping portion 25 is formed with a retaining portion 29 extending in the circumferential direction of the shielded electric wire 10 (see FIG. 1) (hereinafter, the circumferential direction of the shielded electric wire 10 is also simply referred to as the circumferential direction). The retaining portion 29 is formed by hammering out a part of the crimping portion 25 inward in the radial direction. In a state in which the crimping portion 25 is crimped to the shielded electric wire 10, the retaining portion 29 is continuous over the entire circumferential direction.

[0019] As shown in Fig. 3, the crimping portion 25 has a base plate portion 26, a plurality of extension portions 28, and a plurality of claw portions 30. The base plate portion 26 is provided behind the retaining portion 29 (see Fig. 1). Before the crimping portion 25 is crimped to the shielded electric wire 10, the base plate portion 26 has a so-called open barrel shape in which a circumferential portion is cut open along the axial direction. When the crimping portion 25 is crimped to the shielded electric wire 10, the cut open portion of the base plate portion 26 closes to form an annular shape, and the base plate portion 26 is disposed so as to surround the outer periphery of the shielded electric wire 10. An outer periphery side locking portion 33 and an inner periphery side locking portion 37 are provided on the base plate portion 26.

[0020] The outer peripheral locking portion 33 extends in one circumferential direction so as to straddle the cut-out portion of the base plate portion 26 (see FIG. 1). The outer peripheral locking portion 33 has a base portion 34 extending flush from the base plate portion 26, and a locking protrusion 35 folded back radially inward from the protruding end of the base portion 34. The locking protrusion 35 is disposed so as to overlap the inner surface of the base portion 34, and is located radially inward from the base portion 34. The locking protrusion 35 protrudes radially inward from the base plate portion 26. The locking protrusion 35 has a first locking surface 36 facing in the circumferential direction opposite to the protruding direction of the base portion 34.

[0021] The inner circumferential locking portion 37 extends in the opposite direction to the outer circumferential locking portion 33, that is, in the other circumferential direction (see FIG. 1). A rectangular through hole 38 is formed in the rear edge of the base plate portion 26, penetrating in the plate thickness direction (radial direction) so as to be aligned in the circumferential direction with the inner circumferential locking portion 37 (see FIG. 1). Of the inner circumferential surface along the opening edge of the through hole 38, the inner surface that is parallel to the axial direction and is closer to the inner circumferential locking portion 37 in the circumferential direction functions as a second locking surface 39 with which the first locking surface 36 of the locking protrusion 35 faces and locks. Of the rear edge of the base plate portion 26, the region where the inner circumferential locking portion 37 and the through hole 38 are formed protrudes rearward from the portion where the inner circumferential locking portion 37 and the through hole 38 are not formed (see FIG. 4).

[0022] As shown in FIG. 4, the multiple extensions 28 extend in a cantilever shape from the rear edge of the base plate 26 toward the rear in the axial direction. The extensions 28 have a first extension 28A and a second extension 28B. In the axial direction, the dimension of the first extension 28A is larger than the dimension of the second extension 28B. The first extension 28A and the second extension 28B (multiple extensions 28) are arranged adjacent to each other and alternately in the circumferential direction (in FIG. 4, the circumferential direction corresponds to the up-down direction). Specifically, the second extension 28B is arranged on the rear edge of the base plate 26 where the base end of the outer circumferential locking portion 33 is located, and the first extension 28A is arranged on the rear edge of the base plate 26 where the base end of the inner circumferential locking portion 37 is located. The first extending portion 28A is disposed, but the second extending portion 28B is not disposed, in the region of the rear edge of the substrate portion 26 where the through hole 38 is formed. The first extending portion 28A and the second extending portion 28B are disposed in the region of the rear edge of the substrate portion 26 where the inner periphery side locking portion 37 and the through hole 38 are not formed.

[0023] At the rear end edge of the base plate portion 26, the extension portions 28 are arranged biasedly at two locations, the outer circumferential locking portion 33 side and the inner circumferential locking portion 37 side. In other words, the extension portions 28 are arranged in two locations, the outer circumferential locking portion 33 side and the inner circumferential locking portion 37 side. Specifically, at the outer circumferential locking portion 33 side at the rear end edge of the base plate portion 26, a one-side extension portion 28C composed of two second extension portions 28B and one first extension portion 28A is arranged. In the one-side extension portion 28C, one first extension portion 28A is arranged by being sandwiched between two second extension portions 28B in the circumferential direction.

[0024] An other-side extending portion 28D composed of one second extending portion 28B and two first extending portions 28A is disposed on the inner circumferential side engaging portion 37 side at the rear end edge of the base plate portion 26. In the other-side extending portion 28D, one second extending portion 28B is disposed between two first extending portions 28A in the circumferential direction. That is, the first extending portion 28A and the second extending portion 28B are disposed so as to be alternately adjacent to each other in the circumferential direction. In the one-side extending portion 28C and the other-side extending portion 28D, the dimension between adjacent extending portions 28 in the circumferential direction is the same as the dimension in the width direction (circumferential direction) of each extending portion 28. The dimension between the one-side extending portion 28C and the other-side extending portion 28D in the circumferential direction is larger than the dimension between adjacent extending portions 28 in the circumferential direction in the one-side extending portion 28C and the other-side extending portion 28D. For example, a carrier is connected to the rear edge of the base plate portion 26 between the one-side extension portion 28C and the other-side extension portion 28D.

[0025] The multiple claws 30 are provided by bending the rear end of each extension 28 radially inward (see Figs. 1 and 2). Specifically, each claw 30 is bent along a fold F1 extending in the circumferential direction. Both circumferential edges of each claw 30 are parallel to each other and extend along the radial direction (see Fig. 3). The tip edge (rear edge) of each claw 30 is formed to be parallel to the fold F1. In other words, the tip edge (rear edge) of each claw 30 extends in the circumferential direction. At the tip of each claw 30, both circumferential ends are chamfered (C-face).

[0026] The claws 30 have the same radial dimension (projection dimension). In other words, each claw 30 projects radially inward from the inner surface of each extension 28 by the same dimension (see FIG. 3). The folds F1 of the extensions 28 adjacent in the circumferential direction are arranged shifted in the axial direction (see FIG. 4). These claws 30 bite into the outer surface of the sheath 14 of the shielded electric wire 10 by crimping the crimping portion 25 to the shielded electric wire 10 (see FIGS. 2 and 3). This prevents the outer conductor 16 from moving in the axial direction or rotating in the circumferential direction relative to the shielded electric wire 10. Between the claws 30 adjacent in the circumferential direction, the side edges of the claws 30 that extend radially and face each other are shifted in the axial direction (see FIG. 1).

[0027] When performing the crimping process of crimping the crimping portion 25 to the shielded electric wire 10, the crimping portion 25 and the front end portion of the shielded electric wire 10 are set in an applicator (not shown). In the crimping process, the substrate portion 26 is deformed by reducing its diameter and is crimped so as to be wrapped around the outer periphery of the shielded electric wire 10. In a state in which the crimping portion 25 is crimped to the shielded electric wire 10, a region of the crimping portion 25 forward of the retaining portion 29 is crimped to the outer periphery of the sleeve 18 and the folded portion 15, and the folded portion 15 is radially sandwiched between the sleeve 18 and the crimping portion 25 (see FIG. 2). As a result, the folded portion 15, the sleeve 18, and the crimping portion 25 are fixed in an integrated state so as to be conductive.

[0028] In a state where the crimping portion 25 is crimped to the shielded electric wire 10, the retaining portion 29 is disposed between the front end of the sheath 14 and the rear end of the sleeve 18 (see FIG. 2). Then, the outer peripheral locking portion 33 straddles the cut-out portion of the substrate portion 26, and the locking protrusion 35 is housed in the through hole 38 (see FIG. 3). For example, when the crimping process is performed, the inner peripheral locking portion 37, which comes into contact with the inner surface of the base portion 34, is pressed radially inward via the base portion 34. As a result, the inner peripheral locking portion 37, which comes into contact with the inner surface of the base portion 34, is deformed so as to be recessed radially inward (see FIG. 3). In this way, the first locking surface 36 and the second locking surface 39 face each other in the circumferential direction and come into a state of being abutted and locked (see FIGS. 1 and 3). The engagement between the first locking surface 36 and the second locking surface 39 prevents the crimping portion 25 from opening in the circumferential direction, and maintains the state in which the crimping portion 25 is fixed to the outer periphery of the shielded electric wire 10.

[0029] When the crimping portion 25 is crimped to the shielded electric wire 10, each claw portion 30 is pressed radially inward, narrowing the gap between adjacent claw portions 30 in the circumferential direction, and bites into the outer surface of the sheath 14. The claw portions 30 adjacent in the circumferential direction are arranged offset in the axial direction. Therefore, the claw portions 30 do not come into contact with each other in the circumferential direction even if the gap between adjacent claw portions 30 in the circumferential direction narrows.

[0030] Next, the operation of the first embodiment will be described.

[0031] The crimping structure of the electric wire and the outer conductor of the present disclosure includes an open barrel-shaped crimping portion 25 provided on the outer conductor 16 connected to the end of the shielded electric wire 10 and crimped to the outer periphery of the shielded electric wire 10. The crimping portion 25 has a base portion 26, a plurality of extension portions 28, and a plurality of claw portions 30. The base portion 26 is arranged so as to surround the outer periphery of the shielded electric wire 10. The plurality of extension portions 28 are arranged in a line in the circumferential direction of the shielded electric wire 10 in a form of extending in a cantilever shape backward in the axial direction of the shielded electric wire 10 from the rear edge of the base portion 26. The plurality of claw portions 30 are formed by bending the rear end of each extension portion 28 radially inward of the shielded electric wire 10 and bite into the outer surface of the sheath 14 of the shielded electric wire 10. Between the claw portions 30 adjacent to each other in the circumferential direction, the side edges of the claw portions 30 that extend along the radial direction and face each other are shifted in the axial direction. According to this configuration, between the circumferentially adjacent claw portions 30, the side edges of the claw portions 30 facing each other in the circumferential direction are offset in the axial direction, so that it is possible to prevent interference between the adjacent claw portions 30 without narrowing the protruding ends of the claw portions 30. This allows the tips of the wide claw portions 30 to bite into the outer surface of the shielded electric wire 10, so that the outer conductor 16 and the shielded electric wire 10 can be firmly fixed to each other.

[0032] The claw portions 30 are bent along circumferential folds F1, and the folds F1 of circumferentially adjacent extension portions 28 are arranged to be shifted in the axial direction. With this configuration, the simple configuration of shifting the folds F1 of adjacent extension portions 28 in the axial direction can prevent adjacent claw portions 30 from interfering with each other, and thus the tips of the claw portions 30 can be inserted into the outer surface of the shielded electric wire 10 without narrowing them.

[0033] A through hole 38 penetrating in the radial direction is formed in the rear edge of the base plate portion 26, and the region of the rear edge of the base plate portion 26 where the through hole 38 is formed protrudes rearward. The extension portion 28 has a first extension portion 28A and a second extension portion 28B adjacent to each other in the circumferential direction. In the axial direction, the dimension of the first extension portion 28A is larger than the dimension of the second extension portion 28B. The first extension portion 28A is disposed in the region of the rear edge of the base plate portion 26 where the through hole 38 is formed, and the second extension portion 28B is disposed in the region of the rear edge of the base plate portion 26 where the through hole 38 is not formed. According to this configuration, the position where the first extension portion 28A, which has a larger axial dimension, extends from the rear edge of the base plate portion 26 is set to be rearward of the position where the second extension portion 28B, which has a smaller axial dimension, extends from. This makes it possible to prevent the claw portion 30 of the first extending portion 28A from interfering with the claw portion 30 of the second extending portion 28B.

[0034] [Embodiment 2] A second embodiment of the present disclosure will be described with reference to Fig. 5 to Fig. 7. A shielded conductive path 200 having a crimped structure between an electric wire and an outer conductor in the second embodiment differs from the first embodiment in the direction in which the fold F2 extends. Since the other configurations are the same as those in the first embodiment, the same reference numerals are used for the same configurations, and a description of the structure, action, and effect will be omitted. In the drawings, the "front side" and the "rear side" are represented by "F" and "B", respectively.

[0035] As shown in FIG. 5, the axial dimensions of the extensions 128 are the same. The fold F2 extends so as to intersect diagonally with respect to both the axial and circumferential directions. The positions of adjacent folds F2 in the circumferential direction are aligned in the axial direction. In other words, the positions of the multiple folds F2 are aligned in the axial direction and are lined up in a row in the circumferential direction. The leading edge (rear end edge) of each claw 130 is formed so as to be parallel to the fold F2. Each claw 130 is bent along the fold F2 that is diagonal with respect to both the axial and circumferential directions (see FIG. 6). As shown in FIG. 7, when viewed from the axial direction, the leading edge of each claw 130 extends in a direction along the circumferential direction.

[0036] The claws 130 are bent along folds F2 that are oblique to both the axial and circumferential directions, and the positions of adjacent folds F2 in the circumferential direction are aligned in the axial direction. With this configuration, the axial positions of adjacent folds F2 in the circumferential direction are aligned, so that it is possible to prevent interference between adjacent claws 130 and to improve the appearance.

[0037] <Other embodiments> The present disclosure is not limited to the embodiments described above and in the drawings, but is indicated by the claims. The present invention includes the equivalent meaning of the claims and all modifications within the scope of the claims, and is intended to include the following embodiments. (1) Unlike the first and second embodiments, extending portions 228 having three different axial dimensions may be provided as shown in Fig. 8. In this case, it is preferable to make the circumferential width dimension of extending portion 228 having a larger axial dimension larger than that of extending portion 228 having a smaller axial dimension. This makes it difficult for extending portion 228 having a larger axial dimension to bend radially, and makes it easier to maintain the state in which claw portion 230 is bitten into the sheath. (2) By increasing the circumferential width at the tip of the claw (i.e., by increasing the contact dimension of the tip of the claw that contacts the outer surface of the sheath), the outer conductor and the shielded wire can be more firmly fixed. Therefore, unlike the first and second embodiments, by providing an extension 228 over the entire rear edge of the base plate 226 as shown in Fig. 8, the contact dimension of the tip of the claw that contacts the outer surface of the sheath can be increased, and the outer conductor and the shielded wire can be more firmly fixed. (3) Unlike the first and second embodiments, the shielding layer may be made of a metal foil. [Explanation of symbols]
