DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these embodiments. Furthermore, the components in the following embodiments include those that are easily replaceable by those skilled in the art, or those that are substantially the same.

[0011] [First embodiment] The wire harness WH of this embodiment shown in FIGS. 1 and 2 is, for example, a component in which a plurality of electric wires W used for signal communication are bundled together to connect various devices mounted on a vehicle, and the plurality of electric wires W are connected to the various devices using connectors or the like. The wire harness WH of this embodiment includes two electric wires W, a braided body 60 that covers the two electric wires W, and a shield bracket 1 that is electrically connected to the braided body 60 and through which the two electric wires W are inserted. Note that in the drawings, only a portion of the electric wires W is shown, and the internal structure is omitted. The shield bracket 1 includes a shield bracket main body 10, a fixing member 20, and a holder 50. The braided body 60 that covers the two electric wires W is disposed on the outer periphery of the shield bracket main body 10. The fixing member 20 is fixed to a fixed object 70, and is provided so that the shield bracket main body 10 is detachable (i.e., attachable).

[0012] In the following description, the direction in which the electric wire W extends is referred to as the axial direction X, and two directions perpendicular to the axial direction X are referred to as the width direction Y and the height direction Z. In addition, one side of the axial direction X will be referred to as one side X1, and the other side of the axial direction X will be referred to as the other side X2. Similarly, the width direction Y will be referred to as one side Y1 and the other side Y2, and the height direction Z will be referred to as one side Z1 and the other side Z2.

[0013] As shown in FIGS. 1 to 4, the shield bracket main body 10 is formed in a generally cylindrical shape with its axis CL (see FIG. 1) extending along the axial direction X. The shield bracket main body 10 is formed of a conductive metal material such as aluminum or an aluminum alloy. The shield bracket main body 10 has a rectangular tube portion 11 on one side X1 in the axial direction X and an elongated cylindrical portion 12 connected to the other side X2 of the rectangular tube portion 11. The rectangular tube portion 11 has an opening 11a that opens on the one side X1 in the axial direction X, and the elongated cylindrical portion 12 has an opening 12a that opens on the other side X2. The rectangular tube portion 11 has an outer peripheral wall 11b formed around the axial direction X that is formed in a generally rectangular shape that is long in the height direction Z, and the corners are rounded. The elongated cylindrical portion 12 has an outer peripheral wall 12b formed around the axial direction X that is formed in an elliptical cylindrical shape with its major axis aligned along the height direction Z. The long cylindrical portion 12 is connected to a bottom plate 13 formed on the other side X2 in the axial direction X of the rectangular cylindrical portion 11. The rectangular cylindrical portion 11 and the long cylindrical portion 12 are connected with their respective axes aligned and formed integrally.

[0014] A body-side conductive portion 15 is provided on the rectangular tube portion 11 of the shield bracket main body 10. The body-side conductive portion 15 extends along one side Y1 in the width direction Y from an edge portion 11c1 on one side Y1 in the width direction Y at two edge portions 11c1, 11c2 along the height direction Z among the edge portions 11c of the opening 11a of the rectangular tube portion 11 of the shield bracket main body 10. The body-side conductive portion 15 is formed in a substantially plate shape with its plate surface facing the axial direction X. The body-side conductive portion 15 is provided with a plate-shaped body-side contact plate 15a (contact portion) that connects with the edge portion 11c1 of the rectangular tube portion 11 with its plate surface facing the axial direction X, and two bent portions 15b1, 15b2 that are formed by bending each end of the body-side contact plate 15a on one side Z1 and the other side Z2 in the height direction Z to one side X1 in the axial direction X. A bent portion 15b1 is provided at an end portion on one side Z1 in the height direction Z of the body-side contact plate 15a, and a bent portion 15b2 is provided at an end portion on the other side Z2. The bent portions 15b1 and 15b2 are formed to be long in the width direction Y, which is the longitudinal direction of the body-side contact plate 15a. The body-side contact plate 15a of the body-side conductive portion 15 is also provided with a locking opening 15c (locking portion) that opens along the axial direction X. The locking opening 15c is formed in a substantially elongated rectangular shape with the width direction Y as the longitudinal direction.

[0015] Furthermore, two holder locking openings 11d are provided in the outer peripheral wall 11b of the rectangular tube portion 11 of the shield bracket main body 10 (see FIG. 3). The two holder locking openings 11d are provided in the outer peripheral wall 11b on one side Y1 in the width direction Y and the outer peripheral wall 11b on the other side Y2 (not shown), respectively.

[0016] The holder 50 can be made of a resin material and is formed in a generally cylindrical shape having an axis along the axial direction X and an inner peripheral surface shape of a generally rounded rectangle with the height direction Z as the longitudinal direction. The holder 50 is formed by combining a first holder 51 on one side Y1 in the width direction Y and a second holder 52 on the other side Y2. Two electric wires W arranged along the height direction Z are provided inside the holder 50.

[0017] The first holder 51 and the second holder 52 are provided on one side X1 in the axial direction X with band locking portions 51a and 52a extending in a beam-like manner toward the one side X1. Although not shown in detail, the first holder 51 and the second holder 52 are provided on the other side Z2 in the height direction Z with locking portions 54 (see FIG. 4) in the form of a hook-shaped locking protrusion that hooks into a locking hole. The holder 50 is assembled by locking the first holder 51 and the second holder 52 with the locking portions 54. A cable tie 58 is wound around and fastened to the band locking portions 51a and 52a. When the cable tie 58 is fastened, the first holder 51 and the second holder 52 sandwich the two electric wires W arranged therein. In this manner, the holder 50 is fixed to the two electric wires W arranged therein.

[0018] A leaf spring-shaped locking protrusion 50c is provided on one side Y1 in the width direction Y of the first holder 51. The locking protrusion 50c locks into a holder locking opening 11d on one side Y1 in the width direction Y of the rectangular tube portion 11 of the shield bracket main body 10. Similarly, a leaf spring-shaped locking protrusion 50c (not shown) is also provided on the second holder 52, and locks into a holder locking opening 11d (not shown) on the other side Y2 in the width direction Y of the rectangular tube portion 11 of the shield bracket main body 10.

[0019] To attach the shield bracket main body 10 to the electric wires W, first, the ends of the two electric wires W are passed through the opening 12a of the long cylindrical portion 12 of the shield bracket main body 10. That is, the opening 11a of the rectangular cylindrical portion 11 of the shield bracket main body 10 is located on the end side of the two electric wires W. At this time, the braid 60 covering the two electric wires W is peeled off from the electric wires W to be passed through the shield bracket main body 10 by folding it back or the like. Then, the holder 50 is fixed to the two electric wires W on the opening 11a side of the shield bracket main body 10. Then, the shield bracket main body 10 is moved toward the holder 50, and the locking protrusions 50c of the holder 50 are locked into the holder locking openings 11d of the shield bracket main body 10. Then, the holder 50, which is fixed to the two electric wires W, is fixed to the shield bracket main body 10. Therefore, the shield bracket main body 10 is fixed to the two electric wires W via the holder 50. In this way, two electric wires W are inserted inside the shield bracket main body 10. In other words, the shield bracket main body 10 is formed in a substantially cylindrical shape so that two electric wires W can be inserted therethrough.

[0020] A braided body 60 is disposed on the outer periphery of the shield bracket main body 10. The braided body 60 is formed by weaving braided wires made of a conductive metal material such as copper or aluminum, and blocks electromagnetic waves. The braided body 60 is attached to the shield bracket main body 10 so as to cover the end of the braided body 60 from the other side X2 toward one side X1 in the axial direction X of the shield bracket main body 10. The braided body 60 is attached to the outer periphery of the shield bracket main body 10, for example, by crimping a metal shield ring 61. The braided body 60 has a portion that is in close contact with the shield bracket main body 10. Therefore, the braided body 60 is electrically connected to the shield bracket main body 10.

[0021] As shown in FIGS. 5 to 8, the fixing member 20 includes a fixing-side conductive portion 21 and an attachment member 22. The fixing-side conductive portion 21 is formed in a generally crank-like shape from a conductive metal sheet material and is disposed so that its plate surface faces in the axial direction X. The fixing-side conductive portion 21 has a fixing plate 21a (fixing portion) on one side Y1 in the width direction Y and a contact plate 21c on the other side Y2, and the fixing plate 21a and the contact plate 21c are connected by a connecting plate 21b extending from an end of the contact plate 21c on one side Y1 to one side X1 in the axial direction X. The fixing plate 21a has a circular fixing hole 21a1 that opens along the axial direction X.

[0022] The fixed-side conductive portion 21 is fixed to the attachment member 22. Specifically, the contact plate 21c of the fixed-side conductive portion 21 is inserted into the attachment member 22, and the contact plate 21c is fixed to the attachment member 22. The fixed member 20 is fixed to the fixed object 70 by inserting bolts or the like (not shown) into the fixing holes 21a1 and fastening the fixing member 20 to the fixed object 70. At each end of the contact plate 21c on one side Z1 and the other side Z2 in the height direction Z, long bent portions 21d1 and 21d2 are formed by bending the contact plate 21c toward the other side X2 in the axial direction X and extending along the width direction Y. The bent portion 21d1 is provided on the one side Z1 in the height direction Z, and the bent portion 21d2 is provided on the other side Z2. The contact plate 21c is also provided with a spring contact portion 21e including a plurality of spring contacts 21e1.

[0023] 5 and 7, the spring contact 21e1 includes a contact plate 21e11 and a leaf spring portion 21e12. The contact plate 21e11 is disposed substantially parallel to the contact plate 21c and protrudes to one side X1 in the axial direction X. The leaf spring portion 21e12 is connected to the contact plate 21c and supports the contact plate 21e11 so that an elastic force is applied to the contact plate 21e11. The surface of the contact plate 21e11 on the one side X1 in the axial direction X is defined as a contact surface 21e13.

[0024] As shown in FIGS. 5 to 8, the attachment member 22 is formed in a generally rectangular parallelepiped shape that is slightly elongated in the width direction Y. The attachment member 22 is made of a resin material. The attachment member 22 has an internal space that penetrates in the width direction Y, with an attachment opening 22a on one side Y1 and an insertion opening 22b on the other side Y2. The attachment opening 22a opens in a generally rectangular shape that is long in the height direction Z, with portions corresponding to guide portions 22c1 and 22c2 (described later) being wider. As shown in FIG. 6, the insertion opening 22b opens in a generally H-shape. The body-side conductive portion 15 is inserted so that the bent portions 15b1 and 15b2 of the body-side conductive portion 15 and the bent portions 21d1 and 21d2 of the fixed-side conductive portion 21 are oriented in opposite directions in the axial direction X, and the body-side conductive portion 15 is positioned on one side X1 in the axial direction X relative to the contact plate 21c.

[0025] As shown in FIG. 5, the internal space of the mounting member 22 is provided with two guide portions 22c1 and 22c2 formed along the width direction Y. The guide portion 22c1 is provided on one side Z1 in the height direction Z, and the guide portion 22c2 is provided on the other side Z2. The guide portions 22c1 and 22c2 guide the insertion of the body-side conductive portion 15 of the shield bracket body 10 into the mounting member 22. The guide portions 22c1 and 22c2 are formed with a narrow width (distance in the height direction Z) and include a sliding portion 22c3 that is elongated in the width direction Y. The sliding portion 22c3 slides against a surface on one side X1 in the axial direction X of the body-side contact plate 15a of the body-side conductive portion 15 of the shield bracket body 10. As shown in FIG. 7, the guide portions 22c1 and 22c2 have a beam-like shape on one side Y1 in the width direction Y. When the body-side conductive portion 15 is inserted into the attachment member 22, the guide portions 22c1 and 22c2 bend toward one side X1 in the axial direction X from the state shown by the two-dot chain line in FIG. 7, urging the inserted body-side conductive portion 15 toward the other side X2 in the axial direction X, i.e., toward the contact plate 21c. Meanwhile, the contact surface 21e13 of each spring contact 21e1 of the contact plate 21c is provided with an elastic force by the leaf spring portion 21e12. Therefore, the contact surface 21e13 of each spring contact 21e1 is in close contact with the surface of the other side X2 of the body-side contact plate 15a of the body-side conductive portion 15 inserted into the attachment member 22. This electrically connects the fixed-side conductive portion 21 and the body-side conductive portion 15, establishing conduction.

[0026] As shown in FIG. 5, a locking portion 22d is provided between the guide portions 22c1 and 22c2 in the internal space of the attachment member 22. The locking portion 22d is formed in a tongue shape extending toward one side Y1 in the width direction Y. The one side Y1 is a free end and the other side Y2 is a fixed end, allowing it to bend in the axial direction X. As shown in FIG. 8, the locking portion 22d is provided with a flat plate-like main body portion 22d1 and a locking protrusion 22d2 protruding from the plate-like main body portion 22d1 toward the other side X2 in the axial direction X. The locking protrusion 22d2 is connected to the plate-like main body portion 22d1 on the one side Y1 in the width direction Y via a first connecting portion 22r1 with a curvature radius R1, and is connected to the other side Y2 by a second connecting portion 22r2 with a curvature radius R2. The surface of the locking protrusion 22d2 on the other side X2 in the axial direction X is flat.

[0027] The radius of curvature R1 of the first connecting portion 22r1 is formed to be sufficiently smaller than the radius of curvature R2 of the second connecting portion 22r2. Therefore, when the body-side conductive portion 15 is inserted into the attachment member 22 by moving it toward one side Y1 in the width direction Y, the tip of the body-side conductive portion 15 slides against the second connecting portion 22r2, causing the locking portion 22d to bend toward one side X1 in the axial direction X. Thereafter, the restoring force of the locking portion 22d causes the locking protrusion 22d2 to fit into the locking opening 15c, and the locking protrusion 22d2 is locked in the locking opening 15c. On the other hand, when the body-side conductive part 15 attempts to move in the direction of removal (the other side Y2 in the width direction Y), an edge 15c1 on one side Y1 in the width direction Y of the engaging opening 15c abuts against the first connecting part 22r1 and the surface on one side Y1 of the engaging protrusion 22d2 connecting to the first connecting part 22r1, preventing easy removal. The engaging part 22d has a tapered surface 22d3 that extends from the tip of the engaging part 22d toward the engaging protrusion 22d2. By hooking a hook-shaped tool or the like onto the tapered surface 22d3 and lifting the engaging part 22d toward the one side X1 in the axial direction X, the engaging opening 15c is released from the engagement with the engaging protrusion 22d2. The tapered surface 22d3 allows the hook-shaped tool or the like to be smoothly inserted into and hooked onto the engaging part 22d. When the engagement between the engagement opening 15c and the engagement projection 22d2 is released, the main body side conductive portion 15 can be pulled out from the attachment member 22, and the shield bracket main body 10 can be easily removed from the fixing member 20.

[0028] In this way, the shield bracket main body 10 is fixed to the object 70 via the fixing member 20. The shield bracket main body 10 is detachable from the fixing member 20 in the width direction Y. The shield bracket main body 10 can be attached to the electric wire W on which the braided body 60 is provided with the shield bracket main body 10 detached from the fixing member 20. After the work of assembling the electric wire W and the braided body 60 to the shield bracket main body 10 is completed, the body-side conductive portion 15 of the shield bracket main body 10 is inserted into the attachment member 22 of the fixing member 20 to attach the shield bracket main body 10 to the fixing member 20. As a result, the braided body 60 is electrically connected to the body-side conductive portion 15 of the shield bracket main body 10 and the fixed-side conductive portion 21 of the fixing member 20, thereby establishing conduction.

[0029] [Second embodiment] The second embodiment will be described with reference to Figs. 9 to 12. A shield bracket 201 in this embodiment is configured such that the body-side conductive portion 15 and fixing member 20 in the shield bracket body 10 of the shield bracket 1 of the first embodiment are replaced with a fixing member 220 that omits the substantially plate-shaped body-side conductive portion 215 and the attachment member 22. Therefore, the same members and parts as in the first embodiment are denoted by the same reference numerals, and their description will be omitted or simplified. Note that the braid 60 and the fixed object 70 are not shown in Fig. 9.

[0030] 9 and 10, the fixing member 220 of the shield bracket 201 is detachably (i.e., attachable to) the body-side conductive portion 215 of the shield bracket main body 10. The body-side conductive portion 215 extends along the other side Y2 in the width direction Y from an edge 11c2 at the other side Y2 in the width direction Y of two edge portions 11c1 and 11c2 along the height direction Z among the edge portions 11c of the opening 11a of the rectangular tube portion 11 of the shield bracket main body 10, and is bent 90 degrees toward one side X1 in the axial direction X, forming a substantially L-shape when viewed from the height direction Z. The body-side conductive portion 215 has a plate-shaped base 215b connected to the shield bracket main body 10 and extending along the other side Y2 in the width direction Y, and a body-side contact plate 215a (contact portion) extending from an end of the base 215b on the other side Y2 in the width direction Y toward one side X1 in the axial direction X. The base 215b and the main body side contact plate 215a are formed into plates with the same plate width, and the base 215b is arranged with its plate surface facing the axial direction X, while the main body side contact plate 215a is arranged with its plate surface facing the width direction Y.

[0031] The fixed member 220 is configured as a fixed-side conductive portion 221 having a fixed plate 221a (fixed portion) and a contact member 223 having a spring contact portion 221e (see FIG. 11). That is, the entire fixed member 220 is configured as the fixed-side conductive portion 221. In other words, the fixed member 220 has the fixed-side conductive portion 221. The fixed plate 221a extends along the axial direction X and is formed in a generally plate shape with its plate surface facing the width direction Y. A fixing hole 21a1 is provided at an end side of one side X1 in the axial direction X of the fixed plate 221a. An insertion portion 222 is provided at the other side X2 in the axial direction X of the fixed plate 221a. The insertion portion 222 has bent plate portions 222a and 222b that are bent so that plate ends extending from the fixed plate 221a to one side Z1 and the other side Z2 in the height direction Z abut against each other. The insertion portion 222 is surrounded by the bent plate portions 222a and 222b and the fixed plate 221a, and has an insertion hole 222c formed therein that is inserted along the axial direction X. The insertion hole 222c is formed so that its width (distance in the height direction Z) and height (distance in the width direction Y) are slightly larger than the width (distance in the height direction Z) and plate thickness (distance in the width direction Y) of the main body side contact plate 215a, and is formed so that the main body side contact plate 215a can be inserted therein.

[0032] The contact member 223 is formed from a sheet metal material made of a conductive metal. As shown in FIG. 11 , the contact member 223 has two plates, a first plate portion 223a and a second plate portion 223b, and a connecting plate portion 223c connecting the first plate portion 223a and the second plate portion 223b. The first plate portion 223a and the second plate portion 223b are both formed to have substantially the same rectangular plate shape. The connecting plate portion 223c is provided to connect the first plate portion 223a and the second plate portion 223b at their ends on the other side X2 in the axial direction X. The first plate portion 223a and the second plate portion 223b are spaced apart by a distance approximately equal to the plate thickness of the bent plate portions 222a and 222b in the insertion portion 222 of the fixing member 220 (fixed-side conductive portion 221). The first plate portion 223a is provided with a spring contact portion 221e including a plurality of spring contacts 221e1. As shown in Figs. 11 and 12, the spring contact 221e1 is formed to connect the other side X2 in the axial direction X to the first plate portion 223a and to protrude outward from the first plate portion 223a (the other side Y2 in the width direction Y). This supports the spring contact 221e1 so that an elastic force is applied to it. The outer surface of the spring contact 221e1 is formed as a contact surface 221e13. 12, when the body-side contact plate 215a of the body-side conductive portion 215 is inserted into the insertion hole 222c of the insertion portion 222 of the fixed member 220 from the other side X2 in the axial direction X, the contact surface 221e13 of the spring contact 221e1 is brought into close contact with the plate surface on one side Y1 in the width direction Y of the body-side contact plate 215a by elastic force, and the spring contact 221e1 (spring contact portion 221e) and the body-side contact plate 215a are electrically connected. In this way, the body-side conductive portion 215 and the fixed-side conductive portion 221 are electrically connected and conductive.

[0033] In this embodiment, the shield bracket main body 10 is detachable along the axial direction X from a fixing member 220 fixed to a fixed object 70. The insertion portion 222 of the fixing member 220 is detachable from the flat body-side contact plate 215a, so the shield bracket main body 10 can be easily attached to and detached from the fixing member 220.

[0034] [Variations] A modified example of the second embodiment will be described with reference to Figures 13 and 14. In this modified example, the main body-side conductive portion 215 and fixing member 220 (fixed-side conductive portion 221) of the shield bracket 201 of the second embodiment are replaced with a main body-side conductive portion 215A and fixing member 220A (fixed-side conductive portion 221A) of a shield bracket 201A in which the mounting direction of the shield bracket main body 10 is changed. Therefore, the same members and parts as those of the first and second embodiments are denoted by the same reference numerals, and their description will be omitted or simplified. Note that the braided body 60 and the fixed object 70 are not shown in Figure 13.

[0035] The body-side conductive portion 215A of this modified example is formed in a plate shape extending linearly toward the other side Y2 in the width direction Y. The body-side conductive portion 215A is arranged with its plate surface facing the axial direction X. A predetermined range on the tip side of the body-side conductive portion 215A is formed as a body-side contact plate 215Aa (contact portion) into which the insertion portion 222 of the fixing member 220A is inserted and which comes into contact with the spring contact portion 221e of the fixing member 220A. Similar to the fixing member 220 of the second embodiment, the entire fixing member 220A is formed as the fixed-side conductive portion 221A. The fixing plate 221Aa (fixing portion) of the fixed-side conductive portion 221A of this modified example is formed in a substantially L-shaped plate shape when viewed from the height direction Z. The fixing plate 221Aa has a tip portion 221Aa1 where the fixing hole 21a1 is provided, and is arranged with its plate surface facing the width direction Y. On the other hand, the base portion 221Aa2 on which the insertion portion 222 is provided is disposed so that the plate surface faces in the axial direction X.

[0036] In this modified example, the shield bracket main body 10 is detachable in the width direction Y from a fixing member 220A fixed to a fixed object 70. In this modified example, the main body-side conductive portion 215A is linear, but it can also be bent by bending, and the fixed-side conductive portion 221A, which is the fixing member 220A, can also be linear, so that the attachment direction of the shield bracket main body 10 to the fixing member 20 and the direction in which the electric wires W are drawn out can be freely set.

[0037] The shield brackets 1, 201, 201A described above are each formed in a cylindrical shape so that an electric wire W can be inserted therethrough, and include a shield bracket main body 10 having a braided body 60 covering the electric wire W arranged on the outer periphery and electrically connected to the braided body 60, and a fixing member 20, 220, 220A fixed to a fixed object 70 so as to be able to attach the shield bracket main body 10. The wire harness WH includes an electric wire W, the braided body 60 covering the electric wire W, and the shield bracket 1.

[0038] This allows the shield bracket main body 10, to which the electric wire W and the braided body 60 are attached, to be attached to the fixing member 20 that has been fixed to the object 70 in advance, thereby improving workability and ensuring that the electric wire W and the braided body 60 are attached to the shield bracket main body 10.As a result, it is possible to provide a shield bracket 1 and a wire harness WH that can properly fix the shield bracket 1 to the object 70.

[0039] For example, when the wire harness WH is used in a vehicle such as an automobile, the fixing member 20 may use the vehicle body as the fixed object 70, and the braided body 60 may be grounded. In recent years, aluminum wires have been used as the electric wires W in order to increase current and reduce weight, which has resulted in an increase in the size of the electric wires W and reduced workability in routing the electric wires W during routing. For example, when a shield bracket that is directly fixed to the fixed object 70, such as the body, is used, the operation of fixing the shield bracket, to which the aluminum electric wires W and the braided body 60 are attached, to the body with bolts or the like causes a large reaction force of the electric wires W, and therefore, when the shield bracket is fixed to the body, the reaction force of the electric wires W becomes large, making it difficult to achieve good attachment.

[0040] However, with the shield brackets 1, 201, 201A and wire harness WH of this embodiment, the fixing member 20 can be fixed to the body in advance, and then the shield bracket main body 10 to which the electric wires W and the braided body 60 are attached can be attached by inserting it into the fixing member 20, thereby significantly improving attachability. Furthermore, the direction in which the shield bracket main body 10 is attached to the fixing member 20, 220, 220A can be freely set, so attachment can be performed from an appropriate direction depending on the layout of the fixed object 70 of the vehicle or the wire harness WH.

[0041] Furthermore, shield bracket main body 10 has main body-side conductive portions 15, 215, 215A, fixing members 20, 220, 220A have fixed-side conductive portions 21, 221, 221A, and main body-side conductive portions 15, 215, 215A and fixed-side conductive portions 21, 221, 221A are conductive when fixing members 20, 220, 220A are attached to shield bracket main body 10. This allows for easy GND processing of braided body 60 by attaching braided body 60 to shield bracket main body 10 and fixing fixing members 20, 220, 220A to the vehicle body, for example.

[0042] Furthermore, the fixed-side conductive portions 21, 221, 221A are made of sheet metal material and have fixed plates 21a, 221a, 221Aa that serve as fixed portions fixed to the object 70, and spring contact portions 21e, 221e that electrically connect to the body-side contact plates 15a, 215a, 215Aa that serve as contact portions of the body-side conductive portions 15, 215, 215A. This allows for more reliable conduction between the body-side conductive portions 15, 215, 215A and the fixed-side conductive portions 21, 221, 221A.

[0043] Furthermore, fixing member 20 includes attachment member 22 that is fixed to fixing-side conductive portion 21 and has locking portion 22d that locks into locking opening 15c, which is the locking portion of body-side conductive portion 15. This makes it easier to insert body-side conductive portion 15 and facilitates the work of attaching shield bracket body 10 to fixing member 20, while making it difficult for body-side conductive portion 15 to come off, resulting in shield bracket 1 in which shield bracket body 10 is difficult to detach from fixing member 20.

[0044] The shield bracket and the wire harness according to the embodiment of the present invention described above are not limited to the above embodiment, and various modifications are possible within the scope of the claims.

[0045] In the above description, the fixing member is formed to be detachable from the shield bracket main body. However, for example, a structure in which the main body conductive portion of the shield bracket main body cannot be detached from the fixed-side conductive portion after being attached to the fixed-side conductive portion of the fixing member may be adopted. Furthermore, while the present embodiment illustrates the case in which there are two electric wires W, there may be one or three or more electric wires W. Furthermore, in the present embodiment, the shield bracket main body and the fixing member are electrically connected via the main body conductive portion and the fixed-side conductive portion. However, the shield bracket main body and the fixing member may not be electrically connected, and a grounding process may be separately provided. Furthermore, in the first embodiment, the main body conductive portion 15 is configured such that the engaging opening 15c engages with the engaging protrusion 22d2 of the engaging portion 22d. However, this is not limited to this, and other types of engaging structures comprising an engaged portion and an engaging portion may also be used.

[0046] The shield bracket and the wire harness according to this embodiment may be configured by appropriately combining the components of the above-described embodiment and modified examples. [Explanation of symbols]
