[Modes for carrying out the invention]

[0010] Embodiments of the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited by these embodiments. Furthermore, some of the components in the following embodiments may be easily substituted or substantially identical to those that are easily substituted by those skilled in the art.

[0011] Figure 1 is a perspective view of a wire harness WH to which the protector 1A according to this embodiment is applied. The protector 1A of this embodiment shown in Figure 1 is incorporated into a wire harness WH routed in a vehicle such as an automobile. Here, the wire harness WH is, for example, a bundle of multiple wiring materials W used for power supply and signal communication to connect various devices mounted on a vehicle, and the multiple wiring materials W are connected to each device with connectors or the like. The wiring material W is, for example, an insulated wire in which a core wire, which is made up of multiple conductive metal strands bundled together, is covered with an insulating coating. The wiring material W may also be a bundle of multiple insulated wires. The wire harness WH of this embodiment comprises the wiring material W and the protector 1A provided on the wiring material W. In addition, the wire harness WH may also be composed of various other components such as grommets, electrical connection boxes, and fasteners.

[0012] The cable routing material W includes a main line section W1 and branch line sections W2 that branch off from the main line section W1. The protector 1A protects the cable routing material W routed inside it, is fixed to the vehicle, and restricts the routing path of the cable routing material W. The protector 1A has a main body section 10. The main body section 10 is composed of two parts, including a first main body section 11 and a second main body section 12. The protector 1A is installed on the cable routing material W (main line section W1, branch line section W2) by sandwiching it between the first main body section 11 and the second main body section 12. The main body section 10 is provided with a cylindrical section 13. The main line section W1 of the cable routing material W is inserted through the cylindrical section 13. The branch line section W2 and the main line section W1 are led out from the opposite side of the cylindrical section 13 in the direction of extension of the main line section W1 of the main body section 10.

[0013] A terminal mounting portion 20A is provided on the side of the first main body portion 11 of the main body portion 10, to which a terminal 50 is attached. The terminal 50 is provided at the end of the electric wire EW. Here, as shown in Figure 2, the terminal 50 has an electric wire connection portion 51 to which the electric wire EW is joined and electrically connected to the electric wire EW, and an electrical connection portion 52 which is conductive with the electric wire connection portion 51 and electrically connected to the mounting target 80 (connection partner, see Figure 5). In this embodiment, the terminal 50 is a crimp terminal. The terminal 50 is formed by pressing a single sheet metal material, such as punching and bending. The electric wire connection portion 51 has a coating crimp portion 51a to which the coating portion of the electric wire EW, which is an insulated electric wire, is crimped by a barrel piece, and a conductor crimp portion 51b to which the coating portion is peeled off at the end of the electric wire EW to expose the conductor portion, and the exposed conductor portion is crimped by a barrel piece. The electrical connection portion 52 is formed in the shape of a roughly ring-shaped plate, with a circular hole 52a that penetrates through the center.

[0014] In the wire connection section 51, the electric wire EW is arranged on one side of a roughly plate-shaped substrate 51c (see also Figure 7), while the electric wire EW is not arranged on the other side of the substrate 51c. Here, in the wire connection section 51, the outer surface to which the electric wire EW is not connected, i.e., the outer surface of the substrate 51c, is referred to as the first outer surface 51d of the wire connection section 51 (see also Figure 7). On the other hand, in the wire connection section 51, the outer surface to which the electric wire EW is connected, i.e., the outer surface of the barrel piece of the insulation crimp section 51a and the conductor crimp section 51b, is referred to as the second outer surface 51e. Furthermore, in the terminal 50, the side to which the electric wire EW is connected is referred to as the front side 53, and the side to which the electric wire EW is not connected is referred to as the back side 54. With the terminal 50 attached to the terminal mounting portion 20A of the protector 1A, the first outer surface 51d and the second outer surface 51e are arranged on the front side 53 and the back side 54, respectively, along the third direction Z, which will be described later. Such a wire EW is a branch cable branched from the main line W1 and can be an earth wire, and the terminal 50 can be an earth terminal.

[0015] Returning to Figure 1, the protector 1A is fixed to the mounting target 80 (see Figure 5), such as the vehicle body, via the terminal mounting portion 20A. For example, the protector 1A is fixed to the vehicle body by inserting a stud bolt (not shown) protruding from the vehicle body into the terminal mounting portion 20A together with the terminal 50, and then screwing a nut onto the stud bolt to secure it. Alternatively, a bolt (not shown) may be inserted through the terminal 50 and the terminal mounting portion 20A and screwed into a female threaded portion (not shown) provided on the mounting target 80 to fasten it. In this way, once the terminal 50 is assembled to the terminal mounting portion 20A and fixed to the mounting target 80, the terminal 50 is electrically connected to the mounting target 80 via the terminal mounting portion 20A.

[0016] In the following explanation, the direction along which the electric wire EW extends with the terminal 50 attached to the terminal mounting portion 20A of the protector 1A will be referred to as the first direction X, and the two directions perpendicular to the first direction X will be referred to as the second direction Y and the third direction Z. The third direction Z is the direction in which the stud bolt, etc., is inserted through the terminal 50 and the terminal mounting portion 20A. Furthermore, in the following explanation, one side of the first direction X will be referred to as side X1 and the other side as side X2. Similarly, the second direction Y will be referred to as side Y1 and the other side Y2, and the third direction Z will be referred to as side Z1 and the other side Z2.

[0017] As shown in Figures 3 and 4, the terminal mounting portion 20A has a wire connection portion arrangement portion 21A where the wire connection portion 51 is arranged, an electrical connection portion arrangement portion 22 where the electrical connection portion 52 of the terminal 50 is arranged, and a mounting restricting portion 30A which has a first restricting contact portion 31A and a second restricting contact portion 32A that restricts the mounting direction of the terminal 50 in a direction parallel to the plane including the first direction X and the second direction Y, and also restricts the mounting posture of the terminal 50. The terminal mounting portion 20A is formed to protrude from the side surface 11a of the first main body portion 11 of the main body portion 10 of the protector 1A to one side Y1 in the second direction Y. The terminal mounting portion 20A is provided with a substantially flat base portion 25 which protrudes from the side surface 11a of the first main body portion 11 to one side Y1 in the second direction Y, and has its plate surface facing the third direction Z. The base portion 25 is provided extending from the wire connection portion arrangement portion 21A to the electrical connection portion arrangement portion 22. The surface of the base portion 25 on one side Z1 in the third direction Z is connected to a support plate 26c that protrudes from the side surface 11a of the first main body portion 11 on one side Y1 in the second direction Y, with its plate surface facing the first direction X.

[0018] As shown in FIG. 3, a substantially cylindrical collar 22a is provided on the base portion 25 in the electrical connection portion arrangement portion 22. The collar 22a is formed of a metal material or the like and has conductivity. As shown in FIG. 5, the collar 22a has a flange portion 22a1 at the end on one side Z1 in the third direction Z. The collar 22a is press-fitted into the hole 25a of the base portion 25 from one side Z1 in the third direction Z, and the flange portion 22a1 of the collar 22a is locked to the surface on one side Z1 in the third direction Z of the base portion 25 and fixed to the base portion 25. As shown in FIGS. 4 and 5, the end face 22a2 on the other side Z2 in the third direction Z of the collar 22a is substantially flush with the surface on the other side Z2 in the third direction Z of the base portion 25 and is exposed. Further, the electrical connection portion 52 of the terminal 50 is placed on the end face 22a3 of the surface on one side Z1 in the third direction Z of the collar 22a. Here, the electrical connection portion arrangement portion 22 includes the end face 22a3 on one side Z1 in the third direction Z of the collar 22a.

[0019] As shown in FIG. 2, on one side Z1 in the third direction Z of the base portion 25 of the electrical connection portion arrangement portion 22, in order to regulate the movement and deviation of the terminal 50 in a direction parallel to the plane including the first direction X and the second direction Y around the electrical connection portion arrangement portion 22, a substantially annular peripheral wall 24 standing upright toward one side Z1 in the third direction Z is provided. Further, one side X1 in the first direction X of the peripheral wall 24 is an intermittent portion 24b where the peripheral wall 24 is intermittently and widely opened. Further, on the surface on one side Z1 in the third direction Z of the base portion 25, a plurality of recesses 25b for preventing material loss are provided between the peripheral wall 24 in the radial direction of the collar 22a and the collar 22a.

[0020] As shown in FIGS. 3 and 4, the wire connection part arrangement part 21A includes a flat surface 253 on one side Z1 in the third direction Z in the base part 25 of the wire connection part arrangement part 21A. From the surface 253, a first support plate 21h stands upright toward one side Z1 in the third direction Z. The first support plate 21h is formed in a long rectangular plate shape with the first direction X as the longitudinal direction, and the plate surface is arranged facing the second direction Y. At the end of the first support plate 21h on one side Z1 in the third direction Z, a second support plate 21j is provided so as to protrude toward one side Y1 in the second direction Y with the plate surface facing the third direction Z.

[0021] As shown in FIGS. 4 and 5, on the surface 21j1 on the other side Z2 in the third direction Z of the second support plate 21j, a substantially rectangular parallelepiped-shaped protrusion 21k that is long in the second direction Y and protrudes toward the other side Z2 in the third direction Z is provided. The protrusion 21k is provided along the edge on the other side X2 in the first direction X in the second support plate 21j. The protrusion 21k is a first regulation abutting part 31A provided so as to be able to abut against the wire connection part 51 from one side Z1 in the third direction Z. Also, as shown in FIGS. 3 and 5, the surface 253 facing the protrusion 21k in the third direction Z is a second regulation abutting part 32A provided so as to be able to abut against the wire connection part 51 from the other side Z2 in the third direction Z. As shown in FIGS. 4 and 5, on one side X1 in the first direction X of the protrusion 21k, a protrusion 21m that protrudes from the surface 21j1 of the second support plate 21j toward the other side Z2 in the third direction Z is provided. The protrusion 21m is formed in a substantially plate shape with a height lower than that of the protrusion 21k.

[0022] Specifically, as shown in Figures 4 and 5, the projection 21k, which is the first restrictive contact portion 31A, is provided on one side Z1 of the third direction Z relative to the wire connection portion 51, and the surface 253 corresponding to the projection 21k, which is the second restrictive contact portion 32A, is provided on the other side Z2 of the third direction Z relative to the wire connection portion 51, and the space S1 along the third direction Z between the first restrictive contact portion 31A and the second restrictive contact portion 32A is open on at least one side Y1 of the second direction Y. The surface 253 including the second restrictive contact portion 32A is provided on the same plane as the end face 22a3 of the collar 22a on one side Z1 of the third direction Z (a plane parallel to the plane including the first direction X and the second direction Y). In other words, the surface 253 including the second restrictive contact portion 32A is parallel to the end face 22a3. This allows the terminal 50 to be positioned on the terminal mounting portion 20A without any looseness.

[0023] On one side Z1 of the second support plate 21j in the third direction Z, a locking portion 21n is provided, which is formed in a substantially U-shape when viewed from the second direction Y. The locking portion 21n has an opening 21n1 that penetrates in the second direction Y. The locking portion 21n is locked when the locking portion 14a of the cover 14 shown in Figure 1 is inserted into the opening 21n1, and the locking projection 14a1 of the locking portion 14a is locked. The cover 14 is attached after the terminal 50 is attached to the terminal mounting portion 20A.

[0024] As shown in Figure 4, the wire connection section 21A is provided with a support plate 25e that connects to one side X1 in the first direction X of the base section 25 on the electrical connection section 22 side and to the side surface 11a of the first main body section 11. The support plate 25e is provided with its plate surface facing the first direction X. On one side Y1 in the second direction Y of the support plate 25e, a connecting plate 25f is provided that connects the support plate 25e to the base section 25 on the electrical connection section 22 side. The connecting plate 25f is provided with its plate surface facing the second direction Y. The other side X2 in the first direction X of the connecting plate 25f is connected to the base section 25 of the electrical connection section 22. The support plate 25e and the connecting plate 25f support the base section 25, which includes the surface 253 designated as the second restricting contact section 32A, from the other side Z2 in the third direction Z.

[0025] As mentioned above, as shown in Figure 3, a peripheral wall 24 is provided around the electrical connection section 22. The peripheral wall 24 is provided with an intermittent section 24b. The intermittent section 24b includes a guide section 240b, which corresponds to the wire connection section 51. That is, the peripheral wall 24 is provided with an intermittent section 24b in the portion that includes the guide section 240b, which corresponds to the wire connection section 51. The guide section 240b has a guide surface 241b that is continuous with the surface 253 of the base section 25 in the wire connection section 21A. The guide surface 241b, together with the surface 253, is provided as a surface parallel to the surface including the first direction X and the second direction Y. The guide surface 241b is formed in an arc shape that is substantially along the circumferential direction of the peripheral wall 24. A recess 254 is provided between the guide section 240b and the end 24e of one side Y1 in the second direction Y of the peripheral wall 24.

[0026] The terminal 50 is attached to the terminal mounting section 20A as follows. As shown in Figure 6, the terminal 50 is positioned with its front side 53 facing one side Z1 of the third direction Z, the wire connection section 51 is aligned with the guide section 240b of the intermittent section 24b, and the electrical connection section 52 is positioned in the electrical connection section 22 from one side Z1 of the third direction Z. The back side 54 of the electrical connection section 52 is in contact with the end face 22a3 of the collar 22a. Then, the terminal 50 is rotated around an axis along the third direction Z at the center of the hole 52a (in the direction indicated by arrow D5) so that the wire connection section 51 faces the wire connection section 21A. The rotation of the terminal 50 is restricted by the fact that the other side Y2 of the second direction Y in the space S1 between the first restricting contact section 31A and the second restricting contact section 32A is closed by the side surface 11a. In this way, the terminal 50 is positioned in the position shown in Figures 1 and 5. When the terminal 50 is attached to the terminal mounting portion 20A, the back surface 54 of the wire connection portion 51, including the first outer surface 51d, is in contact with the surface 253 of the base portion 25. The conductor crimping portion 51b of the wire connection portion 51 is positioned between the projection 21k and the surface 253 in the third direction Z. The insulation crimping portion 51a of the wire connection portion 51 is positioned between the projection 21k and the projection 21m in the first direction X. The projection 21m serves to prevent the terminal 50 from coming loose. For example, the insulation crimping portion 51a comes into contact with the projection 21m when the wire EW is pulled to one side X1 in the first direction X.

[0027] The electrical connection portion 52 of the terminal 50 is positioned so that the hole 52a is concentric with the collar 22a. By inserting a stud bolt (not shown) or bolt (not shown) erected on the mounting object 80 through the hole 52a and the collar 22a and fastening it, the protector 1A can be fixed to the mounting object 80, and the end face 22a2 of the collar 22a will be in close contact with the mounting object 80, thereby electrically connecting the terminal 50 and the mounting object 80 via the collar 22a. Therefore, the mounting object 80 is the connection partner to which the electrical connection portion 52 of the terminal 50 is electrically connected.

[0028] After assembling the terminal 50, the cover 14 can be attached to the terminal mounting portion 20A. The cover 14 has an insertion portion 14b that is inserted between the second support plate 21j and the surface 253 of the base portion 25. The insertion portion 14b reduces the likelihood of the wire connection portion 51 of the terminal 50 shifting due to vibration or other factors.

[0029] On the other hand, as shown in Figure 7, if an attempt is made to attach the terminal 50 with its back side 54 facing one side Z1 of the third direction Z (the front and back reversed from the normal mounting position in Figure 6), then when attempting to rotate the terminal 50 around the third direction Z to insert the wire connection portion 51 into the wire connection portion arrangement portion 21A, the conductor crimping portion 51b, including the first outer surface 51d of the wire connection portion 51, will come into contact with the projection 21k, making attachment impossible.

[0030] Thus, when attempting to install the terminal 50 in a mounting position other than the normal mounting position by reversing the front side 53 and the back side 54, the projection 21k, which is the first restrictive contact portion 31A, interferes with the first outer surface 51d of the wire connection portion 51 to which the wire EW is not connected. In other words, the first restrictive contact portion 31A is provided so as to be able to contact the first outer surface 51d. Similarly, when attempting to install the terminal 50 by reversing the front side 53 and the back side 54, the surface 253, which is the second restrictive contact portion 32A (the surface 253 facing the projection 21k in the third direction Z), interferes with the second outer surface 51e of the wire connection portion 51 to which the wire EW is connected. In other words, the second restrictive contact portion 32A interferes with the second outer surface 51e. The surface 253 of the portion of the second restrictive contact portion 32A that faces the projection 21k in the third direction Z is provided so as to be able to contact the second outer surface 51e to which the electric wire EW is connected at the electric wire connection portion 51.

[0031] Furthermore, if an attempt is made to insert the terminal 50 from a direction other than the restricted mounting direction of the terminal 50, for example from one side X1 of the first direction X, even if the electrical connection part 52 is lifted to one side Z1 of the third direction Z in an attempt to avoid interference between the electrical connection part 52 and the peripheral wall 24, the first restricting contact part 31A (projection 21k) will interfere with the wire connection part 51.

[0032] In this way, the mounting restricting section 30A aligns the wire connection portion 51 of the terminal 50 with the intermittent portion 24b and positions the electrical connection portion 52 from one side Z1 in the third direction Z to the electrical connection portion arrangement section 22, thereby restricting the mounting direction of the terminal 50 to rotate it in the direction of arrow D5 around the axis along the third direction Z, which is parallel to the plane including the first direction X and the second direction Y, so that the wire connection portion 51 is positioned in the wire connection portion arrangement section 21A, and also restricts the mounting posture of the terminal 50 so that the front side 53 of the terminal 50 faces one side Z1 in the third direction Z.

[0033] The protector 1A described above comprises a main body portion 10 through which the cable material W is inserted, and a terminal mounting portion 20A provided on the main body portion 10 to which a terminal 50 is attached, having a wire connection portion 51 to which the electric wire EW is joined and electrically connected to the electric wire EW, and an electrical connection portion 52 which is conductive with the wire connection portion 51 and electrically connected to the other party. The terminal mounting portion 20A comprises an electrical connection portion arrangement portion 22 in which the electrical connection portion 52 is arranged, a wire connection portion arrangement portion 21A in which the wire connection portion 51 is arranged, and the terminal 50 The mounting restricting portion 30A restricts the mounting direction in a direction parallel to a plane including a first direction X along the direction in which the electric wire EW extends and a second direction Y intersecting the first direction X, and also restricts the mounting posture of the terminal 50. The mounting restricting portion 30A includes a first restricting contact portion 31A that is provided so as to be able to abut the electric wire connection portion 51 from one side Z1 of the third direction Z that intersects the first direction X and the second direction Y, and a second restricting contact portion 32A that is provided so as to be able to abut the electric wire connection portion 51 from the other side Z2 of the third direction Z. The terminal mounting section 20A is provided around the electrical connection section 22 and has a peripheral wall 24 that is erected toward one side Z1 of the third direction Z. The peripheral wall 24 has an intermittent section 24b in the part that includes a guide section 240b which corresponds to the wire connection section 51. The mounting restricting section 30A restricts the wire connection section 51 to be aligned with the intermittent section 24b, the electrical connection section 52 to be positioned in the electrical connection section 22 from one side Z1 of the third direction Z, and the terminal 50 to be rotated around the third direction Z to position the wire connection section 51 in the wire connection section 21A. The wire harness WH is provided with a protector 1A equipped with a terminal mounting section 20A on the wiring material W.

[0034] As a result, when attaching the terminal 50 to the terminal mounting section 20A, even if one attempts to attach it with the front side 53 and back side 54 reversed compared to the correct mounting position, the terminal 50 and the mounting restricting section 30A will interfere, making it impossible to attach the terminal 50. Therefore, since the terminal cannot be attached in an incorrect mounting position, there is no need to visually confirm whether the terminal 50 is attached in the correct mounting position. Thus, a configuration for attaching the terminal 50 to the terminal mounting section 20A can be properly realized. Furthermore, while the peripheral wall 24 restricts the misalignment of the terminal 50, the terminal 50 can be attached to the terminal mounting section 20A by a simple assembly operation that only involves rotating the terminal 50 placed from the third direction Z.

[0035] Furthermore, the first restrictive contact portion 31A is provided so as to be able to contact the first outer surface 51d of the wire connection portion 51 to which the wire EW is not joined, and the second restrictive contact portion 32A is provided so as to be able to contact the second outer surface 51e of the wire connection portion 51 to which the wire EW is joined, and the first outer surface 51d and the second outer surface 51e are arranged on the front and back sides, respectively, along the third direction Z. As a result, if the terminal 50 is to be installed in the wrong mounting position, the first outer surface 51d or the second outer surface 51e of the wire connection portion 51 will come into contact with the mounting restrictive portion 30A, which reduces the chance of accidentally installing the front side 53 and the back side 54 in reverse, especially in the case of a terminal 50 where the appearance of the electrical connection portion 52 on the front side 53 and the back side 54 is the same, such as a crimp terminal.

[0036] Furthermore, if the terminal 50 is mounted from a direction other than the restricted mounting direction of the terminal 50, or if the mounting position of the terminal 50 is other than the correct mounting position, at least one of the first restricting contact portion 31A and the second restricting contact portion 32A will interfere with the terminal 50. As a result, if an attempt is made to mount the terminal 50 from an incorrect mounting position or direction, at least one of the first restricting contact portion 31A and the second restricting contact portion 32A will interfere with the terminal 50, thereby further reducing the likelihood of incorrect assembly of the terminal 50.

[0037] Furthermore, the first restricting contact portion 31A is a projection 21k provided on one side Z1 of the third direction Z relative to the wire connection portion 51, and the second restricting contact portion 32A is a surface 253 provided on the other side Z2 of the third direction Z relative to the wire connection portion 51, and the space S1 between the first restricting contact portion 31A and the second restricting contact portion 32A is open on at least one side Y1 of the second direction Y. This, in combination with the peripheral wall 24, makes it possible to properly realize an installation position in which the terminal 50 is installed by rotating it, which is an installation operation that makes it easy to assemble correctly.

[0038] Furthermore, the protector according to the embodiments of the present invention described above is not limited to the embodiments described above, and various modifications are possible within the scope of the claims.

[0039] In the above description, the terminal mounting portion 20A is mounted with the front side 53 of the terminal 50 facing the other side Z2 of the third direction Z. However, by reversing the configuration of the first restricting contact portion 31A, the second restricting contact portion 32A, and the peripheral wall 24 in the third direction Z, the front side 53 can be mounted facing one side Z1 of the third direction Z. Furthermore, although a crimp terminal was exemplified in the above embodiment, other types of terminals can also be used. For example, instead of a crimping method for the wire connection portion 51, a terminal joined by other joining methods such as resistance welding, ultrasonic bonding, or laser welding can be used.

[0040] The protector and wire harness according to this embodiment may be constructed by appropriately combining the components of the embodiments and modified examples described above. [Explanation of Symbols]
