A connecting portion formed so as to be able to overlap with the fixing portion of the terminal member so that the first insertion hole and the second insertion hole are continuous, and projecting from the connection portion, Including a locking piece that fits into the provided anti-rotation recess, and a fitted portion that is provided on the outer peripheral side of the second insertion hole in the connecting portion, and the terminal member A non-rotating member formed separately, and one of the fitting part and the fitted part is the other Includes at least one protrusion formed in a portion facing said the other selectively mateable plurality of recesses and the protrusions in a portion facing the one is formed.

  The electric wire with a terminal according to the second aspect is the electric wire with a terminal according to the first aspect, wherein the concave portion is a through hole, and the projecting dimension of the convex portion is such that the convex portion protrudes from the through hole. Is set.

  The electric wire with a terminal according to the third aspect is the electric wire with a terminal according to the second aspect, wherein the convex portion projects to the side where the bolt is inserted, and the convex portion is in a state where the bolt is tightened. It is held by the head of the bolt.

  The electric wire with terminal according to the fourth aspect is the electric wire with terminal according to any one of the first to third aspects, wherein the convex portion sandwiches the first insertion hole or the second insertion hole. Two are formed at opposing positions.

  The ground terminal according to the fifth aspect includes: a crimping portion that is crimped to an end of an electric wire; a fixing portion that is connected to the crimping portion and has a first insertion hole through which a bolt can be inserted; A terminal member including a fitting portion provided on the outer peripheral side of the inner peripheral edge portion of the first insertion hole and a second insertion hole into which the bolt can be inserted are formed, and the first insertion hole and the second insertion hole are formed.

{Embodiment}
Hereinafter, the electric wire with terminal 10 and the ground terminal 20 according to the embodiment will be described. Drawing 1 is a perspective view showing electric wire 10 with a terminal concerning an embodiment. 2 is a schematic cross-sectional view taken along line II-II in FIG.

  The electric wire with terminal 10 according to the embodiment includes an electric wire 12 and a ground terminal 20. In the terminal-attached electric wire 10, the ground terminal 20 that is crimped to the electric wire 12 is fixed to the attachment object (here, the vehicle body panel 80) by the bolt 90.

  The electric wire 12 is configured such that a coating portion 16 is formed by extrusion coating of resin on the outer periphery of the core wire 14. The electric wire 12 is used for electrically connecting (in this case, grounding) various electric devices mounted on the vehicle or the like in a state where the electric wire 12 is arranged at an arrangement target location of the vehicle or the like. The covering portion 16 is peeled off at the end of the electric wire 12 where the ground terminal 20 is crimped, and the core wire 14 is exposed.

  The ground terminal 20 includes a terminal member 22 and a detent member 40. The ground terminal 20 is a member that is crimped to the end of the electric wire 12 in order to ground the electric wire 12.

  Next, the terminal member 22 will be described. FIG. 3 is a perspective view showing the terminal member 22.

  The terminal member 22 includes a crimping part 24, a fixing part 32, and a fitting part 38. The terminal member 22 is integrally formed by press molding or the like using a metal such as copper (including a copper alloy) or aluminum (including an aluminum alloy).

  The crimping part 24 is a part to be crimped to the end of the electric wire 12. Specifically, the crimping portion 24 includes a bottom portion 25, a core wire crimping piece 26 and a covering crimping piece 27 erected on the bottom portion 25.

  The bottom portion 25 is formed in a long plate shape, and the electric wire 12 is disposed on the main surface thereof.

  The core wire crimping piece 26 is a portion to be crimped to the core wire 14 exposed at the end of the electric wire 12. The core wire crimping pieces 26 are formed so as to protrude as a pair from both sides of the bottom portion 25 at an intermediate position in the longitudinal direction of the bottom portion 25.

  The coated crimping piece 27 is a portion that is crimped to the end portion of the covering portion 16 closer to the center side than the portion where the core wire 14 at the end portion of the electric wire 12 is exposed. Here, the cover crimping pieces 27 are formed so as to protrude in the same direction as the core crimping piece 26 from both sides of the bottom 25 at the longitudinal end of the bottom 25.

  The core crimping piece 26 and the covering crimping piece 27 are crimped to the electric wire 12 so as to fall down to the electric wire 12 side by a terminal crimping device or the like. Thereby, the crimping part 24 of the terminal member 22 is fixed to the electric wire 12, and the electric wire 12 and the terminal member 22 are electrically connected.

  However, it is not essential that the crimping part 24 has the covering crimping piece 27. The crimping | compression-bonding part 24 should just have the core wire crimping piece 26 at least. However, since the crimping part 24 has the covering crimping piece 27, the crimping part 24 is more firmly fixed to the electric wire 12, and it is possible to suppress the positional deviation or dropping of the terminal member 22 with respect to the electric wire 12.

  The fixing portion 32 is a portion that continues to the crimping portion 24. A first insertion hole 34 through which the bolt 90 can be inserted is formed in the fixing portion 32. Specifically, here, the fixing portion 32 is formed in a disc shape that is continuous with an end portion of the bottom portion 25 opposite to the end portion on which the covering crimping piece 27 is provided in the longitudinal direction. Here, the fixing portion 32 is formed to have a larger diameter than the shaft portion 94 of the bolt 90 where the screw is cut.

  The diameter of the first insertion hole 34 is set to the same diameter as the shaft portion 94 of the bolt 90 where the screw is cut (here, a slightly larger diameter), so that the shaft portion 94 of the bolt 90 can be inserted. Is formed. Further, the first insertion hole 34 is formed with a diameter smaller than that of the fixed portion 32. In addition, the first insertion hole 34 is formed concentrically with the fixed portion 32 here.

  But it is not essential that the fixing | fixed part 32 is formed in disk shape. For example, the fixing part 32 may be formed in a square plate shape. Further, it is not essential that the first insertion hole 34 is formed concentrically with the fixing portion 32. That is, the center of the fixed portion 32 and the center of the first insertion hole 34 may be deviated.

  The fitting portion 38 is provided on the outer peripheral side of the fixed portion 32 with respect to the inner peripheral edge portion of the first insertion hole 34. The fitting portion 38 will be described in detail later together with the fitted portion 48 provided on the rotation preventing member 40.

  Next, the detent member 40 will be described. FIG. 4 is a perspective view showing the detent member 40. FIG. 5 is a plan view showing the detent member 40.

  The detent member 40 includes a connecting portion 42, a locking piece 46, and a fitted portion 48. The terminal member 22 is integrally formed by press molding or the like using a metal such as copper (including a copper alloy) or aluminum (including an aluminum alloy). Further, the rotation preventing member 40 is formed separately from the terminal member 22. The terminal member 22 and the rotation preventing member 40 may be formed of different materials, but are preferably formed of the same material from the viewpoint of electrical connection.

  The connecting portion 42 is formed with a second insertion hole 44 through which the bolt 90 can be inserted. The connecting portion 42 is formed so as to be able to overlap the fixing portion 32 of the terminal member 22 so that the first insertion hole 34 and the second insertion hole 44 are continuous.

  Specifically, here, the connecting portion 42 is formed in the same shape as the fixed portion 32 in plan view. Here, since the fixed portion 32 is formed in a circular shape in plan view, the connecting portion 42 is also formed in a disk shape having the same diameter as the fixed portion 32. Further, the second insertion hole 44 is formed concentrically with the connecting portion 42 and has a diameter equal to that of the first insertion hole 34. As a result, in plan view, one of the connecting portion 42 and the fixing portion 32 is formed so as to overlap exactly without protruding.

  But it is not essential that the connection part 42 is formed in the shape similar to the fixing | fixed part 32 by planar view. That is, here, it is not essential that the connecting portion 42 is formed in a disk shape, and that the connecting portion 42 has a diameter equal to that of the fixed portion 32 even when formed in a disk shape. For example, the connecting portion 42 may be formed in a square plate shape, or may be formed in a disk shape having a larger or smaller diameter than the fixed portion 32.

  In addition, it is not essential that the second insertion hole 44 is formed concentrically with the connecting portion 42 and has the same diameter as the first insertion hole 34. The center of the connecting portion 42 and the center of the second insertion hole 44 may be deviated. The diameter of the second insertion hole 44 may be larger or smaller than the diameter of the first insertion hole 34. That is, the first insertion hole 34 and the second insertion hole 44 only need to be able to be inserted through the shaft portion 94 of the bolt 90 in a state where the terminal member 22 and the rotation preventing member 40 are fitted.

  The locking piece 46 protrudes from the connecting portion 42. The locking piece 46 is formed so as to be fitted into a rotation-preventing recess 84 provided on the attachment object.

  Specifically, the locking piece 46 is formed so as to protrude from the outer peripheral side surface of the connecting portion 42 in a manner orthogonal to the main surface of the connecting portion 42. Here, the locking piece 46 protrudes toward the side opposite to the side where the electric wire 12 is located with respect to the terminal member 22 in a state where the terminal member 22 and the rotation preventing member 40 are fitted. Is formed. The thickness dimension, the width dimension, and the protruding dimension of the locking piece 46 are appropriately set according to the shape of the rotation stopper recess 84 provided in the vehicle body panel 80.

  Further, the distance between the second insertion hole 44 and the locking piece 46 (the distance from the center of the second insertion hole 44 to the locking piece 46) is also a rotation-preventing recess 84 and a bolt insertion recess provided in the vehicle body panel 80. This value is set as appropriate according to the distance from 82, and the position at which the locking piece 46 is orthogonal to the main surface of the connecting portion 42 is determined based on this value. For example, like the latching piece 46 of the electric wire 10 with a terminal which concerns on the 2nd modification mentioned later, after projecting sideways from the connection part 42, you may orthogonally cross to the main surface of the connection part 42. FIG.

  Here, since only one non-rotating recess 84 is formed in the vehicle body panel 80, only one locking piece 46 is provided, but a plurality of non-rotating recesses 84 are formed in the vehicle body panel 80. If it is, a plurality of locking pieces 46 may be formed. That is, the locking piece 46 only needs to be formed according to the number of the rotation-preventing recesses 84 formed in the vehicle body panel 80. However, even when a plurality of the rotation-preventing recesses 84 are formed in the vehicle body panel 80, it is not essential to make the number of the locking pieces 46 equal to the number of the rotation-stopping recesses 84.

  The fitted portion 48 is provided on the outer peripheral side of the connecting portion 42 with respect to the inner peripheral edge portion of the second insertion hole 44.

  One of the fitting portion 38 and the fitted portion 48 includes at least one convex portion 50 formed in a portion facing the other. On the other side, a plurality of concave portions 60 that can be selectively fitted with the convex portions 50 are formed in a portion facing one side. The rotation preventing member 40 is attached to the terminal member 22 by fitting the convex portion 50 and the concave portion 60 together.

  Here, the convex part 50 protrudes to the side where the bolt 90 is inserted. And the convex part 50 is pressed by the head 92 of the volt | bolt 90 in the state in which the volt | bolt 90 was fastened.

  Here, two convex portions 50 are formed at positions facing each other with the first insertion hole 34 or the second insertion hole 44 interposed therebetween. Hereinafter, when distinguishing the two convex portions 50, one is referred to as one convex portion 51 and the other is referred to as the other convex portion 52.

  Specifically, here, the fitting portion 38 includes two convex portions 50. As shown in FIG. 1, the bolt 90 is inserted from the side where the electric wire 12 is positioned with respect to the ground terminal 20. For this reason, the two convex portions 50 are formed so as to protrude from the main surface of the fixing portion 32 continuous from the bottom portion 25 to the main surface on which the electric wire 12 is positioned.

  Further, the two convex portions 50 are respectively formed at positions 180 degrees apart around the center of the first insertion hole 34. More specifically, the two convex portions 50 are concentric with the first insertion hole 34, and are formed at a portion intersecting with the extending direction of the bottom portion 25 on the circumference having a diameter larger than that of the first insertion hole 34. Has been. In other words, on the circumference, one convex portion 51 is formed at a position closest to the electric wire 12, and the other convex portion 52 is formed at a position farthest from the electric wire 12.

  Here, the convex portion 50 is formed by forming a cut in a part of the fixed portion 32 and bending a portion of the fixed portion 32 where the cut is formed.

  More specifically, the one convex portion 51 formed at a position closest to the electric wire 12 is formed as follows. That is, two incisions along the radial direction are formed in the fixed portion 32, and a circumferential incision connecting end portions on the outer peripheral side among the end portions of the two incisions is formed. A portion surrounded by the cut becomes a rectangular piece. Then, the rectangular piece is bent toward the protruding direction of the core wire crimping piece 26 around the line connecting the inner peripheral ends of the two cuts along the radial direction. Further, the one convex portion 51 is formed by bending the front end of the rectangular piece to the outer peripheral side and then bending back to the fixing portion 32 side.

  The other convex portion 52 formed at a position farthest from the electric wire 12 is formed as follows. That is, two cuts along the radial direction are formed in the fixed portion 32 up to the outer periphery of the fixed portion 32, and a portion sandwiched between the two cuts is a rectangular piece. Then, the rectangular piece is bent toward the protruding direction of the core wire crimping piece 26 around the line connecting the inner peripheral ends of the two cuts along the radial direction. Further, the other convex portion 52 is formed by bending the front end of the rectangular piece toward the outer peripheral side and then bending back to the fixing portion 32 side.

  In addition, it is not essential that the two convex portions 50 are provided. Only one convex portion 50 may be provided, or three or more convex portions 50 may be provided. As the number of the convex portions 50 increases, the terminal member 22 and the rotation preventing member 40 are more firmly fitted. Further, the smaller the number of convex portions 50, the more easily the terminal member 22 and the rotation preventing member 40 can be fitted.

  Further, even when two convex portions 50 are provided, the two convex portions 50 are located at positions facing each other across the first insertion hole 34 or the second insertion hole 44 (here, the first insertion hole 34). It is not essential to be provided. For example, the two convex portions 50 may be provided at positions shifted by 90 degrees in the circumferential direction. However, the more the two convex portions 50 are separated in the circumferential direction, the more firmly the terminal member 22 and the rotation preventing member 40 are fitted.

  Moreover, it is not essential that the convex part 50 protrudes to the side where the bolt 90 is inserted (the side where the electric wire 12 is positioned with respect to the fixed part 32). The convex portion 50 may protrude on the side opposite to the side where the bolt 90 is inserted (the side opposite to the side where the electric wire 12 is positioned with respect to the fixed portion 32). In this case, the terminal member 22 is positioned on the head 92 side of the bolt 90, and the rotation preventing member 40 is positioned between the terminal member 22 and the vehicle body panel 80. In this case, the electric wire 12 can be pulled out in the direction in which the locking piece 46 is located with respect to the first insertion hole 34 as in a first modification described later.

  Moreover, although the convex part 50 is formed inside the outer periphery of the head 92 of the volt | bolt 90 in radial direction, this is not essential. The convex portion 50 may be formed outside the outer periphery of the head portion 92 of the bolt 90 in the radial direction. That is, the two convex portions 50 do not have to be in contact with the head portion 92 of the bolt 90 in a state where the bolt 90 is tightened. However, the convex portion 50 is formed on the inner side of the outer periphery of the head portion 92 of the bolt 90 in the radial direction, so that the convex portion 50 is pressed by the head portion 92 of the bolt 90 with the bolt 90 tightened. . Thereby, the fitting state of the terminal member 22 and the detent | locking member 40 can be maintained more reliably.

  Moreover, the shape of the convex part 50 is not restricted to what was mentioned above. For example, the rectangular piece may not be bent back to the fixed portion 32 side. However, the dimension of the convex part 50 in the radial direction can be increased by bending the rectangular piece back to the fixed part 32 side. Thereby, when the convex part 50 and the recessed part 60 fit, it becomes difficult to remove | deviate. Further, for example, the convex portion 50 may be projected from the fixed portion 32 like the core wire crimping piece 26 projected from the bottom portion 25. That is, the shape of the convex part 50 should just be formed in the shape which can be fitted in the recessed part 60. FIG.

  Here, a plurality of recesses 60 are formed in the fitted portion 48. Specifically, the plurality of recesses 60 are concentric with the second insertion hole 44 and are formed on the same circumference as the circumference where the two projections 50 are located.

  More specifically, the plurality of (in this case, 12) recesses 60 are formed at a constant pitch over the entire circumference on the same circumference. Thereby, the position of the locking piece 46 can be shifted by a certain angle (here, 30 degrees) with respect to the first insertion hole 34.

  Here, the recess 60 is a through hole. And the protrusion dimension of the convex part 50 is set so that the convex part 50 may protrude from the said through-hole.

  Moreover, the recessed part 60 is formed so that the convex part 50 may be contacted at the inner peripheral edge part (here, the convex part 50 is pressed down). Specifically, the radial dimension of the concave portion 60 is set to be the same as or smaller than the radial dimension of the convex portion 50 (here, slightly smaller), and the convex portion 50 is formed on the inner peripheral edge of the concave portion 60. The inner peripheral edge portion of the concave portion 60 is formed so as to hold down the convex portion 50. Thereby, after fitting the convex part 50 and the recessed part 60, it can suppress that the rotation prevention member 40 remove | deviates from the terminal member 22 in the step before the earth terminal 20 is bolted. . However, by setting the circumferential dimension of the recess 60 equal to or smaller than the circumferential dimension of the projection 50, the projection 50 is sandwiched between the inner peripheral edges of the recess 60, and the inner periphery of the recess 60. The part may be formed so as to press the convex part 50.

  As shown in FIG. 5, the plurality of recesses 60 are all formed in the same shape, but may be partially different as long as the protrusions 50 can be fitted.

  Further, it is not essential that the plurality of recesses 60 be formed at a constant pitch over the entire circumference, and some pitches may be different. For example, on the circumference where the concave portion 60 is formed, the concave portion 60 is formed only in the opposite one-fourth circumferential portion, and the concave portion 60 is not formed in the remaining circumferential portion. Also good.

  It is not essential that twelve recesses 60 are formed. It may be less than 12 or more than 12. For example, if 24 concave portions 60 are formed at a constant pitch, the position of the locking piece 46 with respect to the first insertion hole 34 can be shifted by 15 degrees. The greater the number of recesses 60, the smaller the angle at which the locking piece is displaced. Thereby, the direction which can draw out the electric wire 12 with respect to the recessed part 82 for bolt insertion can be increased.

  Moreover, it is not essential that the recessed part 60 is a through-hole. The concave portion 60 may be formed in a manner of being recessed from one main surface of the fixing portion 32 or the connecting portion 42 (here, the connecting portion 42) toward the other main surface. In this case, it is preferable that the projecting dimension of the convex part 50 is set to be equal to or smaller than the depth dimension of the recess, and the main surfaces of the fixing part 32 and the connecting part 42 are in contact with each other.

  The position of the locking piece 46 with respect to the first insertion hole 34 can be changed by changing the concave portion 60 fitted to the convex portion 50. FIG. 6 is an explanatory diagram showing a state in which the position of the locking piece 46 with respect to the first insertion hole 34 has been changed.

  Here, since the 12 concave portions are formed at a constant pitch, the position of the locking piece 46 with respect to the first insertion hole 34 is increased by 30 each time the position of the concave portion 60 fitted to the convex portion 50 is shifted by one. Can be shifted by degrees. In FIG. 6, the position of the recessed part 60 fitted to the convex part 50 is shifted from the state of FIG. Accordingly, the position of the locking piece 46 with respect to the first insertion hole 34 is shifted by 90 degrees, and the locking piece 46 that was on the extension line in the longitudinal direction of the electric wire 12 in FIG. 1 is orthogonal to the longitudinal direction of the electric wire 12 in FIG. Have come to a position to do.

  According to the terminal-attached electric wire 10 according to the embodiment, at least one convex portion 50 is formed on one of the fitting portion 38 and the fitted portion 48 and the other is selectively fitted with the convex portion 50. Since a plurality of possible recesses 60 are formed, the rotation preventing member 40 is attached to the terminal member 22 when the projections 50 and the recesses 60 are fitted. And since the position of the latching piece 46 with respect to the 1st penetration hole 34 can be changed by changing the recessed part 60 fitted to the convex part 50, it is electric wire 12 with respect to the hole for volt | bolts 90 provided in the vehicle. The degree of freedom in the direction that can be pulled out can be increased. Thereby, the electric wire 12 can be easily pulled out in a direction according to a route arranged in the vehicle.

  Further, since the protrusion 60 is a through hole, and the protruding dimension of the convex portion 50 is set so that the convex portion 50 protrudes from the through hole, the bolt 40 is attached to the terminal member 22 after the rotation preventing member 40 is mounted. The anti-rotation member 40 is unlikely to come off before 90 tightening.

  Moreover, the convex part 50 protrudes in the side into which the volt | bolt 90 is inserted, and the volt | bolt 90 is tightened by forming the convex part 50 in the position of the head 92 of the volt | bolt 90 in the state which the bolt 90 was tightened. Since the convex portion 50 is pressed by the head portion 92 of the bolt 90, it is possible to prevent the rotation preventing member 40 from coming off after the bolt 90 is tightened.

  In addition, since the two convex portions 50 are formed at positions facing each other across the first insertion hole 34 or the second insertion hole 44, the bolt 90 is mounted after the rotation preventing member 40 is attached to the terminal member 22. The anti-rotation member 40 is unlikely to come off the terminal member 22 before tightening.

  Moreover, since the position of the latching piece 46 with respect to the 1st penetration hole 34 can be changed by changing the position of the recessed part 60 fitted with the convex part 50, the position of the latching piece with respect to the hole for volt | bolts differs. Even if it is necessary to prepare a plurality of types, a single type of ground terminal 20 can be used. This eliminates the need to newly raise a mold or the like or to set up a wire crimping facility. For this reason, man-hours and costs can be reduced.

{First modification}
Next, the terminal-attached electric wire 10A and the ground terminal 20A according to the first modification will be described. FIG. 7 is an exploded perspective view showing the terminal-attached electric wire 10A according to the first modification.

  10A of terminal electric wires which concern on a 1st modification differ from the electric wire 10 with a terminal which concerns on embodiment by the recessed part 60 being formed in the fitting part 38A, and the to-be-fitted part 48A including the convex part 53. FIG.

  Specifically, a plurality of (here, twelve) recesses 60 are formed in the fixed portion 32 of the terminal member 22A at a constant pitch on the same circumference. In addition, two convex portions 53 are formed at positions facing the connecting portion 42 of the rotation preventing member 40 </ b> A across the second insertion hole 44. The two convex portions 53 protrude from the connecting portion 42 in the direction opposite to the protruding direction of the locking piece 46. Thereby, the two convex parts 53 protrude in the direction in which the bolt 90 is inserted. Here, the two convex portions 53 are formed in the same shape as the other convex portion 52 in the embodiment.

  The effect similar to the electric wire 10 with a terminal which concerns on embodiment can be acquired also by 10A of electric wires with a terminal which concerns on a 1st modification.

  Further, according to the terminal-attached electric wire 10A according to the first modified example, since the rotation preventing member 40A is located between the terminal member 22A and the vehicle body panel 80, the direction in which the locking piece 46 is located with respect to the bolt insertion recess 82. Also, the electric wire 12 can be pulled out. Thereby, the freedom degree of the direction which can draw out the electric wire 12 with respect to the hole for bolt insertion provided in the vehicle can further be raised.

{Second modification}
Next, the terminal-attached electric wire 10B and the ground terminal 20B according to the second modification will be described. FIG. 8 is an exploded perspective view showing the terminal-attached electric wire 10B according to the second modification.

  The terminal-attached electric wire 10B according to the second modification is different from the terminal-attached electric wire 10 according to the embodiment in the shape of the locking piece 46B provided in the rotation preventing member 40B.

  Specifically, the locking piece 46 </ b> B is formed so as to protrude in the axial direction of the second insertion hole 44 after protruding in the radial direction from the outer peripheral edge of the connecting portion 42. This is because the diameter of the connecting portion 42 is smaller than the distance from the center of the bolt insertion recess 82 of the vehicle body panel 80 to the rotation stop recess 84. In the case where the diameter of the connecting portion 42 is larger than the distance from the center of the bolt insertion recess 82 of the vehicle body panel 80 to the rotation preventing recess 84, a locking piece projects from the main surface of the connecting portion 42. There is also a possibility. That is, the locking piece 46B is formed at a position such that the distance from the center of the second insertion hole 44 corresponds to the distance from the center of the bolt insertion recess 82 of the vehicle body panel 80 to the rotation stop recess 84. Just do it.

  The effect similar to the electric wire 10 with a terminal which concerns on embodiment can be acquired also by the electric wire 10B with a terminal which concerns on a 2nd modification.

  In addition, each structure demonstrated by the said embodiment and each modification can be suitably combined unless it mutually contradicts.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
