[0009] 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.
[0010] For convenience of explanation, FIGS. 2 to 4 show only the cross section of the grounding target portion to which the ground terminal is fixed.
[0011] [Embodiment] The wire harness WH shown in Figure 1 is an assembly component made by bundling together multiple wiring materials W used for power supply and signal communication, for example, to connect various devices mounted on a vehicle or between ground surfaces.
[0012] The wire harness WH includes a wiring material W and an earth terminal 1 provided at an end of the wiring material W. The wire harness WH may further include a grommet, a protector, a fixing device, etc.
[0013] The wiring material W is a so-called earth wire. The wiring material W includes, for example, a conductive core wire W1 and a covering portion W2 that covers the outside of the core wire W1.
[0014] The core wire W1 is formed by bundling together a plurality of metal wires made of a conductive metal, such as copper, copper alloy, aluminum, aluminum alloy, etc. The core wire W1 may be made by twisting together a plurality of wires, or may be a metal rod, etc.
[0015] The covering portion W2 is a wire covering that covers the outer periphery of the core wire W1 and is formed by extrusion molding an insulating resin material, for example.
[0016] At least one end of the wiring material W has the covering W2 stripped away to expose the core wire W1, and an earth terminal 1 is provided at the end of this exposed core wire W1. The earth terminal 1 is attached to the grounding target part A and serves as a so-called earth.
[0017] Here, the ground target part A is formed by applying a non-conductive film such as a paint film to the surface of a housing made of a conductive metal material or the like, thereby forming a planar ground plane AS. As shown in FIG. 1 , the ground target part A in this embodiment is formed in a plate shape, with its front surface functioning as a first ground plane AS1 and its back surface functioning as a second ground plane AS2. Here, the back surface of the ground target part A functioning as the second ground plane AS2 is the surface A2 on one side in the thickness direction of the ground target part A. The front surface of the ground target part A functioning as the first ground plane AS1 is the surface A1 on the other side in the thickness direction of the ground target part A. The ground target part A is formed, for example, by a body panel of a vehicle. The ground target part A also has a through-hole AH1 into which the tip end of the ground terminal 1 can be inserted and a through-hole AH2 into which the fixing part of the ground terminal 1 can be inserted. The ground terminal 1 is typically fixed facing the ground plane AS and is electrically connected to the ground target part A via a contact part with the ground plane AS, thereby being grounded.
[0018] The earth terminal 1 of this embodiment includes a wiring material connection portion 100, a main body portion 200 including a contact portion with the ground surface AS, and an anchor portion 300 located on the base end side of the main body portion 200. In addition, the earth terminal 1 of this embodiment has the main body portion 200 formed in a stepped shape, and a plurality of protrusions 400 are provided at the contact portion with the ground surface AS, and the interaction between the plurality of protrusions 400 and the anchor portion 300 facilitates the work of attaching and detaching the earth terminal 1 to the ground target portion A, thereby realizing a configuration that can improve workability. Below, each component of the earth terminal 1 will be described in detail with reference to Figs. 1 to 4.
[0019] In the following description, of the first, second, and third directions that intersect with one another, the first direction will be referred to as the "X direction," the second direction will be referred to as the "Y direction," and the third direction will be referred to as the "Z direction." The X, Y, and Z directions are perpendicular to one another. The X direction typically corresponds to the height direction of the ground terminal 1 and the thickness direction of the ground target area A. The YZ directions typically correspond to the extension direction of the ground target area A, the Y direction typically corresponds to the longitudinal direction of the ground terminal 1, and the Z direction typically corresponds to the short-side direction (also referred to as the width direction) of the ground terminal 1, unless otherwise specified. In the following description, the directions will be described as directions when the ground terminal 1 is attached to the ground target area A via the anchor part 300.
[0020] Furthermore, the lower side in the X direction typically corresponds to the surface A2 side on one side in the X direction of the ground target area A, the side where the anchor part 300 is located relative to the ground target area A (inside the ground target area A), etc. Furthermore, the upper side in the X direction typically corresponds to the surface A1 side on the other side in the X direction of the ground target area A, the side where the wiring material connection part 100 is located relative to the ground target area A (outside the ground target area A), etc.
[0021] In the following description, the direction in which the anchor part 300 is fixed to the ground target part A may be referred to as the "fixing direction." The fixing direction is typically the direction in which the anchor part 300 is inserted into the through-hole AH2 of the ground target part A, and corresponds to the direction in which one protrusion part 400 supported by the ground target part A is rotated around the rotation fulcrum F1 when the earth terminal 1 is assembled to the ground target part A (rotation direction θ1 shown in FIG. 2 ).
[0022] The earth terminal 1 is formed from a conductive metal, such as copper, copper alloy, aluminum, aluminum alloy, etc., and is formed by pressing a single sheet of metal into a single unit, including the wiring material connection portion 100, main body portion 200, and anchor portion 300.
[0023] The wiring material connecting portion 100 is a portion to which the wiring material W is connected. As shown in FIG. 1 , the wiring material connecting portion 100 includes a base portion 110 where the terminal of the wiring material W is disposed, a core wire connecting portion 120 to which the core wire W1 of the wiring material W is connected, and a covering connecting portion 130 to which the covering portion W2 of the wiring material W is connected. The core wire connecting portion 120 and the covering connecting portion 130 are each configured to include, for example, a pair of crimping pieces, and the wiring material W is crimped by crimping the core wire W1 together with the crimping piece of the core wire connecting portion 120 and crimping the covering portion W2 together with the crimping piece of the covering connecting portion 130. Note that the connection method between the wiring material connecting portion 100 and the wiring material W is not limited to the crimping method described above, and other methods may be used.
[0024] The main body portion 200 is connected to the core wire connecting portion 120 of the wiring material connecting portion 100, and is positioned opposite the ground surface AS of the ground target portion A when the anchor portion 300 is fixed to the ground target portion A. As shown in FIGS. 1 to 3 , the main body portion 200 is formed in a plate shape as a whole. The main body portion 200 is also formed in a Z-shape and has multiple bent portions. More specifically, the main body portion 200 includes a base-end main body portion 210, a tip-end main body portion 220 positioned with a step below the base-end main body portion 210 in the X direction, and a connecting portion 230 positioned between the base-end main body portion 210 and the tip-end main body portion 220. The main body portion 200 also has bent portions between the base-end main body portion 210 and the connecting portion 230 and between the connecting portion 230 and the tip-end main body portion 220.
[0025] The base-end side main body portion 210 is the portion that is connected to the wiring material connection portion 100. As shown in Fig. 1, the base-end side main body portion 210 is formed in a substantially rectangular shape. The base-end side main body portion 210 is formed in a planar shape, and when fixed to the ground target portion A via the anchor portion 300, it is positioned opposite the first ground surface AS1, which is the surface of the ground target portion A.
[0026] As shown in FIG. 1, the base end main body portion 210 is connected to the base portion 110 of the wiring material connecting portion 100 on the base end side in the Y direction, and is connected to the connecting portion 230 on the tip end side in the Y direction.
[0027] 1, the base-end main body 210 has, as the protrusion 400, a first protrusion 410 that protrudes downward in the X direction, and is electrically connected by contacting the first protrusion 410 with the first ground plane AS1. Details of the first protrusion 410 will be described later.
[0028] 1, the tip side main body portion 220 is formed in a substantially polygonal shape, tapering toward the tip side in the Y direction. The tip side main body portion 220 is formed in a planar shape, and when attached to the ground target portion A via the anchor portion 300, it is positioned opposite the second ground surface AS2, which is the back surface of the ground target portion A.
[0029] 1, the distal end side main body portion 220 is connected to the connecting portion 230 on the base end side in the Y direction. In other words, the proximal end side main body portion 210 is connected to the distal end side main body portion 220 via the connecting portion 230 on the distal end side in the Y direction.
[0030] 1, the tip side main body 220 has a second protrusion 420 that protrudes upward in the X direction as the protrusion 400, and is electrically connected by contacting the second protrusion 420 with the second ground plane AS2. Details of the second protrusion 420 will be described later.
[0031] The size of the base-end main body portion 210 and the size of the tip-end main body portion 220 are not particularly limited, but it is preferable that the length in the Y direction of the base-end main body portion 210 be set longer than the length in the Y direction of the tip-end main body portion 220.
[0032] The connecting portion 230 is a portion that connects the base-end main body portion 210 and the tip-end main body portion 220. As shown in Fig. 1, the base-end main body portion 210 is formed in a substantially rectangular shape. The connecting portion 230 is formed in a planar shape, and when fixed to the ground target portion A via the anchor portion 300, it is positioned so as to intersect with the first ground surface AS1 and the second ground surface AS2.
[0033] As shown in FIG. 1, the connecting portion 230 is connected to the base end side in the Y direction with the base end main body portion 210, and to the tip end side in the Y direction with the tip end main body portion 220.
[0034] The anchor portion 300 is a portion that can fix the main body portion 200 to the ground target portion A. As shown in FIGS. 1 to 3, the anchor portion 300 is provided on the base end side in the Y direction of the main body portion 200, and protrudes from one surface of the base end side main body portion 210 (main body portion 200) in the X direction, i.e., from the back surface of the base end side main body portion 210 (main body portion 200).
[0035] 2 and 3, the anchor part 300 has a pair of arms 320 supported in a cantilevered manner by a shaft part 310 extending from the main body part 200. The anchor part 300 is inserted into a through hole AH2 formed in the ground target part A by bending the pair of arms 320, and the tips of the arms 320 are respectively engaged with the edges of the through hole AH2, thereby fixing the anchor part 300 to the ground target part A.
[0036] The anchor portion 300 may be formed, for example, by bending the metal plate that constitutes the main body portion 200, etc., or may be formed separately from the metal plate that constitutes the main body portion 200, etc., and then joined to the metal plate.
[0037] Next, the protrusions 400 provided on the base end main body portion 210 and the tip end main body portion 220 will be described in more detail with reference to FIGS.
[0038] As described above, the protrusion 400 of this embodiment is a portion that is formed on the main body 200 and is electrically conductive when in contact with the ground plane AS. As shown in Fig. 1, the protrusion 400 is formed on the base-end main body 210 and includes a first protrusion 410 that protrudes downward in the X direction, and a second protrusion 420 that is formed on the tip-end main body 220 and protrudes upward in the X direction.
[0039] The first protrusion 410 is provided on the distal end side of the base-end main body portion 210 in the Y direction, and more specifically, is provided on the distal end side (connecting portion 230 side) of the anchor portion 300 in the Y direction. The first protrusion 410 protrudes from one surface of the base-end main body portion 210 (main body portion 200) in the X direction, i.e., from the back surface of the base-end main body portion 210 (main body portion 200). As shown in FIG. 1 , the first protrusion 410 is formed in a plate shape with its thickness direction aligned with the Z direction. The first protrusion 410 is formed in a substantially triangular shape when viewed from the Z direction, and is tapered downward in the X direction. The first protrusions 410 are provided at the ends along the Y direction, and the first protrusions 410 are positioned at intervals in the Z direction. As shown in Figure 3, each base end main body portion 210 is attached to surface A1 of the ground target area A, and is therefore positioned so that the pointed portion of the first protrusion portion 410 comes into contact with the paint film PF1 on the first ground surface AS1 (see Figure 4).
[0040] The second protrusion 420 is provided on the tip side of the tip side main body 220 in the Y direction, and protrudes from the surface on the other side in the X direction of the tip side main body 220 (main body 200), i.e., from the surface of the tip side main body 220 (main body 200). As shown in FIG. 1, the second protrusion 420 is formed in a plate shape with its thickness direction aligned with the Y direction. The second protrusion 420 is formed in a substantially triangular shape when viewed from the Y direction, and is tapered upward in the X direction. As shown in FIG. 3, the second protrusion 420 is attached to the surface A2 of the ground target area A, and therefore the pointed portions of the second protrusions 420 are positioned so as to contact the coating film PF2 of the second ground surface AS2 (see FIG. 4).
[0041] Although the shape of the protrusion 400 has been described as being substantially triangular, the shape is not particularly limited as long as it can contact the ground surface AS and provide electrical conductivity. The protrusion 400 may be, for example, circular, rectangular, polygonal, or thorn-shaped.
[0042] Furthermore, the positions of the first protrusion 410 and the second protrusion 420 are not particularly limited, but it is preferable that the distance Y1 between the first protrusion 410 and the anchor portion 300 is set to be longer than the distance Y2 between the first protrusion 410 and the second protrusion 420.
[0043] Next, the installation operation of the ground terminal 1 will be described with reference to FIGS.
[0044] First, the worker inserts the tip end side of the main body 200 into the through hole AH1 formed in the ground target part A. At this time, as shown in Fig. 2, the tip end side main body 220 and the connecting part 230 of the earth terminal 1 are inserted into the through hole AH1, and the first protrusion 410 formed on the base end side main body 210 is supported by the first ground surface AS1 of the ground target part A.
[0045] Then, the worker rotates the main body 200 in the rotation direction θ1 around the first protrusion 410. At this time, the ground terminal 1 rotates so that the base-end main body 210 approaches the first ground surface AS1, and the tip-end main body 220 approaches the second ground surface AS2. Then, the anchor 300 located on the base-end side of the base-end main body 210 in the Y direction is inserted into the through-hole AH2 along the fixing direction (the rotation direction θ1 shown in FIG. 2), and the main body 200 is fixed to the ground target part A via the anchor 300 (see FIG. 3).
[0046] Therefore, with this configuration, the ground terminal 1 can bring the second protrusion 420 formed on the distal main body 220 into contact with and penetrate the coating film PF2 of the grounding target area A, thereby bringing the second protrusion 420 into contact with the second grounding surface AS2 located inside the coating film PF2 and establishing electrical continuity (see FIG. 4). Also, the ground terminal 1 can bring the first protrusion 410 formed on the proximal main body 210 into contact with and penetrate the coating film PF1 of the grounding target area A, thereby bringing the first protrusion 410 into contact with the first grounding surface AS1 located inside the coating film PF1 and establishing electrical continuity (see FIG. 4).
[0047] Furthermore, in the ground terminal 1, the length of the base-end main body portion 210 in the Y direction is set longer than the length of the tip-end main body portion 220 in the Y direction, and the distance Y1 between the first protrusion 410 and the anchor portion 300 is set longer than the distance Y2 between the first protrusion 410 and the second protrusion 420 (see FIG. 3 ). Therefore, the ground terminal 1 can apply a large force to the second protrusion portion 420 by the principle of leverage through rotational motion with the first protrusion 410 as the rotation fulcrum F1, the base end side of the base-end main body portion 210 as the operating force point, and the second protrusion 420 as the point of application. More specifically, when a force (operating force) is applied to the base end side of the base-end main body portion 210, a moment is generated which is the operating force multiplied by the distance from the first protrusion 410 to the operating force point, and the moment generated on the base-end main body portion 210 side is generated on the tip-end main body portion 220 side as a reaction. Since the distance from the first protrusion 410 to the operating force point is set longer than the distance (distance Y2) from the first protrusion 410 to the second protrusion 420, a force greater than the operating force applied to the operating force point can be applied to the second protrusion 420, which is the point of action.
[0048] Therefore, with this configuration, the ground terminal 1 can be installed with a lighter operating force by using the first protrusion 410 as the rotation fulcrum F1 of the main body 200 to bring the second protrusion 420 into contact with the coating film PF2 on the ground target area A to establish electrical continuity, and the first protrusion 410 into contact with the coating film PF1 on the ground target area A to establish electrical continuity. Therefore, the ground terminal 1 can be attached to the ground target area A with a lighter operating force, and fixed to the ground target area A via the anchor 300.
[0049] As described above, the ground terminal 1 of this embodiment includes a wiring material connection portion 100 to which a conductive wiring material W is connected, a base-end main body portion 210 connected to the wiring material connection portion 100, a tip-end main body portion 220 located at a step along the X direction (first direction) relative to the base-end main body portion 210, and a main body portion 200 having a connecting portion 230 connecting the base-end main body portion 210 and the tip-end main body portion 220, and an anchor portion 300 protruding to one side along the X direction from the base-end main body portion 210 and fixable to a ground target portion A. Furthermore, the ground target portion A to which the ground terminal 1 is attached includes, when the anchor portion 300 is fixed to the ground target portion A, a first ground surface AS1 facing the base-end main body portion 210 on one side in the X direction and a second ground surface AS2 facing the tip-end main body portion 220 on the other side in the X direction. In addition, the base end main body portion 210 of the earth terminal 1 has a first protrusion portion 410 protruding to one side along the X direction, and the tip end main body portion 220 has a second protrusion portion 420 protruding to the other side along the X direction, and when the anchor portion 300 is fixed to the first ground surface AS1, the first protrusion portion 410 of the base end main body portion 210 comes into contact with the first ground surface AS1 and is electrically connected, and the second protrusion portion 420 of the tip end main body portion 220 comes into contact with the second ground surface AS2 and is electrically connected.
[0050] With this configuration, the ground terminal 1 can bring the second protrusion 420 into contact with the second ground surface AS2 and establish electrical continuity by rotating the main body 200 in the rotational direction θ1 while the first protrusion 410 is in contact with the first ground surface AS1. Furthermore, the ground terminal 1 can bring the first protrusion 410 into contact with the first ground surface AS1 and establish electrical continuity, while at the same time fixing the anchor 300 to the grounding target part A. Therefore, the interaction between the anchor 300 and the protrusion 400, which includes the first protrusion 410 and the second protrusion 420, and the ground terminal 1 can be attached to and detached from the grounding target part A more easily, improving workability.
[0051] Furthermore, the first protrusion 410 of the ground terminal 1 described above is supported by the first ground surface AS1 when the anchor part 300 is fixed to the first ground surface AS1, and serves as a rotation fulcrum F1 for the main body part 200. With this configuration, the ground terminal 1 can apply force to the second protrusion 420 by the principle of leverage through rotational motion with the first protrusion 410 as the rotation fulcrum F1, the base end side of the base-end main body part 210 as the operating force point, and the second protrusion 420 as the point of action. When a force (operating force) is applied to the base end side of the base-end main body part 210, a moment is generated that is the operating force multiplied by the distance from the first protrusion 410 to the operating force point, and the moment generated on the base-end main body part 210 side generates a reaction on the tip-end main body part 220 side. Therefore, when the anchor portion 300 located on the operating force point side is fixed to the ground target portion A, the force applied to the operating force point is applied to the point of action, thereby bringing the second protrusion portion 420 into contact with the second ground surface AS2 and establishing electrical conductivity.
[0052] Furthermore, the ground target portion A described above is formed in a plate-like shape with its thickness direction along the X direction, and has a through hole AH1 into which the tip side main body portion 220 and the connecting portion 230 can be inserted, with the surface A1 on the other side in the X direction constituting the first ground surface AS1 and the surface A2 on one side in the X direction constituting the second ground surface AS2. Furthermore, the tip side main body portion 220 of the main body portion 200 is positioned with a step on one side in the X direction relative to the base side main body portion 210, and with the tip side main body portion 220 and the connecting portion 230 inserted into the through hole AH1 and the anchor portion 300 fixed to the first ground surface AS1, the base side main body portion 210 is fixed to the first ground surface AS1, and the tip side main body portion 220 is fixed to the second ground surface S2. With this configuration, with the tip-side main body 220 and the connecting portion 230 inserted into the through-hole AH1, the ground terminal 1 can support the first protrusion 410 on the first ground surface AS1, which is the front surface of the ground target portion A. Furthermore, by fixing the anchor portion 300 to the ground target portion A, the ground terminal 1 can bring the second protrusion 420 into contact with the second ground surface AS2, which is the back surface of the ground target portion A, for electrical continuity, and at the same time bring the first protrusion 410 into contact with the first ground surface AS1 for electrical continuity.
[0053] The ground terminal 1 according to the embodiment of the present invention described above is not limited to the above embodiment, and various modifications are possible within the scope of the claims.
[0054] For example, the shapes of the ground terminal 1 and the ground target portion A to which the ground terminal 1 is attached are not limited to those shown in FIGS. 1 to 4. The ground terminal may have a distal main body portion positioned above the proximal main body portion in the X direction, with a step therebetween. The ground target portion to which the ground terminal is attached may include two contact portions extending in the YZ directions and spaced apart in the X direction. In this case, the ground terminal may be positioned between ground surfaces facing each other, with the first protrusion supported by one ground surface positioned below in the X direction. Furthermore, by rotating the ground terminal 1 around the first protrusion as a rotation fulcrum and fixing the anchor portion to one ground surface, the second protrusion can be brought into contact with another ground surface positioned above in the X direction for electrical conduction, while the first protrusion can be brought into contact with one ground surface for electrical conduction.
[0055] Furthermore, the number of protrusions 400 formed on the main body 200 is not particularly limited.
[0056] Furthermore, the main body 200 may have a support protrusion that supports the main body by contacting a part to be grounded, in addition to the protrusion 400 that contacts the ground surface and is electrically connected.
[0057] The ground terminal according to this embodiment may be configured by appropriately combining the components of the above-described embodiments and modified examples. [Explanation of symbols]
