Description

[Technical Field]

[0001] The present invention relates to a wiring structure of a wire harness and a wire harness. [Background technology]

[0002] Conventionally, there has been proposed a wire harness including a plurality of electric wires and a plurality of cylindrical shielding members wrapped around the electric wires. In this type of wire harness, a plurality of shielding members are wrapped around the plurality of electric wires in a corresponding manner, so that electromagnetic waves emitted from the electric wires into the surroundings are captured (or blocked) by the shielding members, thereby suppressing noise from being generated in surrounding electronic devices, etc. (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-7404 Summary of the Invention [Problem to be solved by the invention]

[0004] In automotive wiring harnesses, when electric wires are passed through an opening connecting the inside and outside of the vehicle body, a grommet made of an elastic material is used to seal the gap between the opening and the electric wires to prevent water or foreign matter from entering the vehicle body through the opening. A grommet generally has a main body portion corresponding to the shape of the opening to which the electric wires are attached and a tubular insertion portion through which the electric wires are inserted. In conventional wire harnesses, each electric wire is individually sheathed in a shielding member, and the electric wires and the shielding member sheathed around the electric wires are inserted into corresponding insertion holes in the insertion portion of the grommet. This allows the inner circumferential surface of each insertion portion to easily adhere to the outer circumferential surface of each shielding member. This ensures the wire harness's waterproofing. However, the need to sheathe each electric wire with a shielding member increases manufacturing costs.

[0005] On the other hand, there is also a shielding structure in which multiple electric wires are collectively sheathed by a single shielding member. While this shielding structure is preferable from the viewpoint of cost reduction, it is difficult for the inner peripheral surface of the insertion portion to adhere closely to the outer peripheral surface of the shielding member, and there is ample room for improvement from the viewpoint of waterproofing.

[0006] The present invention has been made in consideration of the above-mentioned circumstances, and its object is to provide a wiring harness arrangement structure and a wire harness that are cost-effective and have excellent water-tightness in a shielding structure in which a shielding member collectively sheathes multiple electric wires, and the wire harness. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the wiring harness arrangement structure according to the present invention has the following features. A wiring structure of a wire harness that is routed from the inside to the outside of a vehicle and connects an external device arranged outside the vehicle cabin with an internal device arranged inside the vehicle cabin, The wire harness includes: A plurality of wires; a shielding member that collectively covers the plurality of electric wires in a partial axial region of the wire harness from a connection portion with the external device to a panel that separates the interior and exterior of the vehicle; a fixing member provided at one end of the region and electrically connected to one end of the shielding member; a grommet having an insertion portion through which the electric wires are inserted so as to be in close contact with outer peripheral surfaces of the plurality of electric wires, The grommet is Located at a position different from the region, A panel is attached to the panel so as to close an opening formed in the panel. R, The fixing member and the grommet are arranged at a predetermined distance in the axial direction of the electric wire to expose the electric wire. The wiring harness is arranged in a structure.

[0008] Furthermore, in order to achieve the above-mentioned object, the wire harness according to the present invention has the following features. A wire harness that is routed from the inside to the outside of a vehicle and connects an external device disposed outside the vehicle cabin with an internal device disposed inside the vehicle cabin, A plurality of wires; a shielding member that collectively covers the plurality of electric wires in a part of an axial region from a connection portion with the external device to a panel that separates the interior and exterior of the vehicle; a fixing member provided at one end of the region and electrically connected to one end of the shielding member; The plurality Electric wire and a grommet having an insertion portion through which the electric wire is inserted so as to be in close contact with the outer peripheral surface of each of the The grommet is Located at a position different from the region, A panel is attached to the panel so as to close an opening formed in the panel. R, The fixing member and the grommet are arranged at a predetermined distance in the axial direction of the electric wire to expose the electric wire. It must be a wire harness. [Effects of the Invention]

[0009] The wiring structure of a wire harness and the wire harness according to the present invention will be described below. In the wire harness, a plurality of electric wires are collectively covered by a shielding member in a partial axial region from a connection portion with an external device located outside the vehicle cabin to a panel separating the interior and exterior of the vehicle. This ensures shielding performance in the above region (hereinafter also referred to as the "shielded section") of the wire harness. Additionally, the wire harness has electric wires inserted into grommets attached to the panel at positions different from the above region, and the wire harness is arranged inside the vehicle cabin. Since the interior of the vehicle cabin is generally a watertight space watertightly isolated from the exterior of the vehicle cabin, the wire harness according to the present invention is divided into a shielded section and a waterproof section as described above. In the case of the wire harness according to the present invention, in which a shielding member collectively covers a plurality of electric wires, if the shielded section and the waterproof section were not separated, the shielding member covering the plurality of electric wires collectively would be inserted through the insertion portion of the grommet. In such a case, the inner peripheral surface of the insertion portion is unlikely to come into close contact with the outer peripheral surface of the shielding member, and water or the like is likely to enter the vehicle interior from outside through the gap between the outer peripheral surface of the shielding member and the inner peripheral surface of the insertion portion. However, the wire harness of this configuration, which is divided into a shielded section and a waterproof section, can prevent water or the like from entering the vehicle interior. In addition, since the shielded section and the watertight section are separated, it is not necessary to provide a shield structure such as a shielded section in the watertight space, which reduces the manufacturing costs of the wire harness. As a result, the wiring structure and the wiring harness of the present configuration can reduce the cost of manufacturing the wiring harness and are excellent in watertightness.

[0010] The present invention has been briefly described above. The details of the present invention will become clearer by reading the following detailed description of the invention (hereinafter referred to as "embodiments") with reference to the accompanying drawings. [Brief explanation of the drawings]

[Figure 2] FIG. 2 is a simplified enlarged view of the main part of FIG. [Figure 3] FIG. 3 is a front view of the wire harness according to the embodiment of the present invention. [Figure 4] FIG. 4 is a view of the wire harness shown in FIG. 3 with the corrugated tube removed. [Figure 5] FIG. 5 is a cross-sectional view taken along line AA in FIG. [Figure 6] FIG. 6 is a cross-sectional view taken along the line BB in FIG. DETAILED DESCRIPTION OF THE INVENTION

[0012] <Embodiment> Hereinafter, a wire harness 1 according to an embodiment of the present invention will be described with reference to the drawings. As shown in Figs. 1 and 2, the wire harness 1 is typically used in a state where an electric wire 10 is inserted into an opening (not shown) formed in a panel P that separates the interior and exterior of a passenger compartment R1 of an automobile V, and a grommet 60 is used to close the gap between the opening of the panel P and the electric wire 10. Specifically, in a wiring structure 100 for the wire harness 1, the wire harness 1 is used to connect an inverter IV outside the passenger compartment R2 and a battery BT inside the passenger compartment R1.

[0013] 3 and 4, for ease of explanation, the upper side of the paper is referred to as "one end side (also simply referred to as "one end")," and the lower side of the paper is referred to as "the other end side (also simply referred to as "the other end")." More specifically, the end of the electric wire 10 where the terminal 70 is provided is the one end, and the end of the electric wire 10 where the connector 20 is provided is the other end.

[0014] As shown in FIGS. 3 and 4 , the wire harness 1 includes a plurality of electric wires 10 (a pair in this example), a braided conductor 30 collectively covering the plurality of electric wires 10 in a partial region S in the axial direction of the wire harness 1 (the vertical direction on the paper) from an inverter IV outside the vehicle compartment R2 to a panel P, an exterior member 50 covering the electric wires 10 and the braided conductor 30 in the region S, a fixing member 40 provided at one end of the region S, a connector 20 provided at the other end of the region S (which is also one end of the wire harness 1), and a grommet 60 attached to the panel P at a position different from the region S and spaced a predetermined distance from the fixing member 40. The braided conductor 30 corresponds to the "shielding member" of the present invention. The configurations of the components constituting the wire harness 1 will be described below in order.

[0015] First, the electric wires 10 will be described. Each of the electric wires 10 is composed of a round rod-shaped conductor 11 and a cylindrical insulating coating 12 that covers the conductor (see FIGS. 5 and 6). The electric wires 10 are exposed outside the vehicle cabin R2 by a predetermined distance between the fixing member 40 and the grommet 60 (see FIGS. 3 and 4). The exposed amount of the electric wires 10 is adjusted so as not to affect surrounding devices.

[0016] If the fixing member 40 and the grommet 60 are not spaced apart by a predetermined distance, the fixing member 40 and the grommet 60 will interfere with each other when the wire harness 1 is routed, as described below. For this reason, the fixing member 40 and the grommet 60 are spaced apart by a predetermined distance, and further, the electric wires 10 are exposed outside the vehicle cabin by the predetermined distance between the fixing member 40 and the grommet 60. However, if the fixing member 40 and the grommet 60 do not interfere with each other when the wire harness 1 is routed, it is preferable that there is no space between the fixing member 40 and the grommet 60 so that the electric wires 10 are not exposed. In other words, it is preferable that the region S is the entire region outside the vehicle cabin from the connector 20 to the panel P (specifically, the grommet 60 attached to the panel P).

[0017] Next, the braided conductor 30 is arranged cylindrically on the outer periphery of the covering so as to collectively surround the coverings of the plurality of electric wires 10 in a partial axial region S of the wire harness 1 (see FIG. 4). The conductors 11 of the electric wires 10 and the braided conductor 30 are typically made of copper or a copper alloy.

[0018] Next, the outer casing 50 will be described. The outer casing 50 is made of, for example, a synthetic resin formed into a tubular shape, and has a bellows portion in which concave grooves and convex strips extending in the circumferential direction of the tube are alternately arranged in the longitudinal direction (the up-and-down direction on the paper in FIG. 3). As shown in FIG. 3, the outer casing 50 is arranged to cover the electric wire 10 and the braided conductor 30 in the region S. In this example, a corrugated tube is used as the outer casing 50. However, a member other than a corrugated tube may be used as the outer casing 50 as long as it functions to protect the electric wire 10 and the braided conductor 30 inside the outer casing 50 from external interference, etc.

[0019] Next, the fixing member 40 will be described. As shown in FIG. 5, the fixing member 40 is composed of a housing 41 through which the electric wire 10 is inserted and which holds the electric wire 10, a shield shell 42 which is assembled to cover the outer peripheral surface of the housing 41, and an attachment portion 43 which is provided on the shield shell 42. The fixing member 40 is, for example, a shield bracket and is typically made of a metal material. The housing 41 is composed of, for example, two members, a first member 41a and a second member 41b, and holds the electric wire 10 by sandwiching it between the first member 41a and the second member 41b. The first member 41a and the second member 41b are maintained in a locked state by locking with each other via locking portions (not shown). One end of the braided conductor 30 is attached to the outer peripheral surface of the other end of the shield shell 42, and the one end of the braided conductor 30 is crimped by a crimping ring (not shown) or the like. As a result, when the wire harness 1 is routed in an automobile V, the mounting portion 43 is attached to the vehicle body, and the fixing member 40 is connected to the vehicle body and earthed (this point will be described later).

[0020] Next, the connector 20 will be described. As shown in FIGS. 3 and 4, the connector 20 is provided in the region S and at the other end of the wire harness 1. As shown in FIGS. 3 to 4 and 6, the connector 20 includes a terminal 23 electrically connected to the conductor 11 at the other end of the electric wire 10, a housing 21 that accommodates the terminal 23 and holds the electric wire 10, and a shield shell 22 that is assembled to cover the outer circumferential surface of the housing 21. The housing 21 is composed of, for example, two members, a first member 21a and a second member 21b, and holds the electric wire 10 by sandwiching it between the first member 21a and the second member 21b. The first member 21a and the second member 21b are maintained in a locked state by locking with each other at locking portions (not shown). The other end of the braided conductor 30 is attached to the outer circumferential surface of one end of the shield shell 22, and the other end of the braided conductor 30 is crimped by a crimping ring (not shown) or the like. As a result, the connector 20 is electrically connected to the inverter IV by the terminal 23, and is also grounded to, for example, the housing (not shown) of the inverter IV by a shield shell (not shown) or the like that the connector 20 has.

[0021] Thus, the region S formed by the electric wire 10, the braided conductor 30, the exterior member 50, the fixing member 40, and the connector 20 is a so-called shielded section. In this example, the region S is located outside the vehicle compartment R2 (see FIG. 2), and suppresses noise in surrounding electronic devices and the like caused by electromagnetic waves emitted from the electric wire 10 to the surroundings outside the vehicle compartment R2.

[0022] Next, the grommet 60 will be described. As shown in FIGS. 2 to 4, the grommet 60 is disposed outside the region S at a predetermined distance from the fixing member 40. The grommet 60 integrally includes a main body 61 having a shape corresponding to the shape of the opening of the panel P in order to close the opening (specifically, to cover the opening from the other end side), and an insertion portion 62 for inserting the plurality of electric wires 10. The grommet 60 is typically made of an elastic material such as rubber. The insertion portion 62 has a plurality of insertion holes (a pair in this example) corresponding to the plurality of electric wires 10, and is configured to come into close contact with the outer peripheral surfaces of the plurality of electric wires 10 inserted into the plurality of insertion holes, respectively. The configuration of each component constituting the wire harness 1 has been described above.

[0023] Next, as shown in Figures 1 and 2, a wiring harness installation work for attaching the wire harness 1 to a panel P will be described. First, the electric wires 10, the braided conductor 30, the exterior member 50, the fixing member 40, the connector 20, the grommet 60, and the terminal 70 are prepared. Next, the braided conductor 30 is sheathed so as to collectively cover the plurality of electric wires 10 in a partial region S in the axial direction of the wire harness 1, and the exterior member 50 is sheathed around the braided conductor 30 so as to cover the electric wires 10 and the braided conductor 30 in the region S.

[0024] Furthermore, a terminal 70 is connected to one end of each of the plurality of electric wires 10, and a terminal 23 is connected to the other end of the plurality of electric wires 10 so that a connector 20 is disposed at the other end of the plurality of electric wires 10. The electric wires 10 are held in a housing 21, and a shield shell 22 is assembled to the housing 21. Furthermore, the electric wires 10 are held in a housing 41, and a shield shell 42 integrally formed with an attachment portion 43 is assembled to the housing 41 so that a fixing member 40 is disposed at one end of the region S. Note that it does not matter whether the sheathing of the braided conductor 30 around the electric wires 10, the sheathing of the electric wires 10 and the braided conductor 30 with the sheathing member 50, the connection of the terminals 70 and the connector 20 to the ends of the electric wires, and the attachment of the fixing member 40 to the electric wires 10 are performed before or after the above steps.

[0025] Next, once the connector 20, the braided conductor 30, and the fixing member 40 are arranged in their predetermined positions, one end of the braided conductor 30 is attached to the outer peripheral surface of the other end of the fixing member 40 (specifically, the shield shell 42), and one end of the braided conductor 30 is crimped to the other end of the fixing member 40 (the shield shell 42) using a crimping ring (not shown) or the like. Similarly, the other end of the braided conductor 30 is attached to the outer peripheral surface of one end of the connector 20 (specifically, the shield shell 22), and the other end of the braided conductor 30 is crimped to the one end of the connector 20 (the shield shell 22) using a crimping ring (not shown) or the like. This electrically connects the connector 20, the braided conductor 30, and the fixing member 40 to each other.

[0026] Next, grommet 60 is attached to panel P so that main body 61 of grommet 60 closes the opening of panel P located vertically above region S (specifically, covers the opening from the other end side). Attaching grommet 60 to panel P located vertically above region S prevents water and the like from entering vehicle interior R1. Note that the method of attaching grommet 60 to panel P is not limited.

[0027] Next, the terminal 23 of the connector 20 is electrically connected to a terminal (not shown) of the inverter IV, and the shield shell 22 of the connector 20 is grounded to the housing of the inverter IV (not shown). As a result, noise such as electromagnetic waves generated in the electric wire 10 is transmitted to the shield shell 22 via the braided conductor 30, and then from the shield shell 22 to the housing of the inverter IV. In other words, the connector 20 (shield shell 22), the braided conductor 30, and the fixing member 40 are grounded to the housing of the inverter IV. As a result, noise to surrounding electronic devices and the like caused by electromagnetic waves emitted from the electric wire 10 to the surroundings outside the vehicle compartment R2 is suppressed.

[0028] Next, the electric wires 10 located on one end side of the region S are inserted into the insertion holes (not shown) in the insertion portions 62 of the grommet 60. Specifically, first, the insertion portions 62 are elastically deformed using a predetermined switch (not shown) to expand the diameter, and then the electric wires 10 are inserted into the insertion portions 62. At this time, the electric wires 10 and the terminals 70 provided at one ends of the electric wires 10 are positioned in the vehicle interior R1, and a predetermined gap is provided between the fixing member 40 and the grommet 60, and the electric wires 10 located at this position are bent vertically upward.

[0029] As described above, the plurality of electric wires 10 are inserted into the plurality of insertion holes of the corresponding insertion portions 62, so that the outer peripheral surface of each electric wire 10 is tightly attached to the inner peripheral surface of the corresponding insertion hole. This improves the waterproofing between the outer peripheral surface of the electric wire 10 and the inner peripheral surface of the insertion hole, which can be a path for water or the like to enter from the outside of the vehicle compartment R2 into the inside of the vehicle compartment R1.

[0030] Next, the fixing member 40 (specifically, the wire harness 1) is attached to the vehicle body using the attachment portion 43. At this time, the fixing member 40 is attached to a surface different from the panel P (see FIG. 2). As a result, noise such as electromagnetic waves generated in the electric wire 10 is transmitted to the shield shell 42 of the fixing member 40 via the braided conductor 30, and then from the shield shell 42 to the vehicle body. In other words, the connector 20 (shield shell 22), the braided conductor 30, and the fixing member 40 (shield shell 42) are earthed to the vehicle body. As a result, noise to surrounding electronic devices and the like caused by electromagnetic waves emitted from the electric wire 10 to the surroundings outside the vehicle compartment R2 is suppressed.

[0031] Next, the terminal 70 provided at one end of the electric wire 10 inside the vehicle interior R1 is connected to a terminal of the battery BT (not shown). As a result, the wire harness 1 electrically connects the inverter IV outside the vehicle interior R2 and the battery BT inside the vehicle interior R1. With the above steps, the wire harness 1 is completed, and the work of attaching the wire harness 1 to the panel P is also completed.

[0032] As described above, the wiring structure 100 of the wire harness 1 does not have a shield structure in the vehicle interior R1, which is a waterproof section, but has a shield structure in the vehicle exterior R2, which is a shield section. In other words, the wiring structure 100 of the wire harness 1 is divided into a shield section and a waterproof section. This allows costs to be reduced by not providing a shield structure in the waterproof section.

[0033] In addition, in a case where the braided conductor 30 collectively covers a plurality of electric wires 10 as in the wire harness 1 of the present embodiment, if the shielded section and the waterproof section are not separated, the braided conductor 30 collectively covering the plurality of electric wires 10 is inserted into the insertion portion 62 of the grommet 60. In such a case, the inner peripheral surface of the insertion portion 62 is unlikely to be in close contact with the outer peripheral surface of the braided conductor 30, and water or the like is likely to infiltrate from the outside of the vehicle compartment R2 toward the inside of the vehicle compartment R1 through the gap between the outer peripheral surface of the braided conductor 30 and the inner peripheral surface of the insertion portion 62. However, the wire harness 1 of the present embodiment, which separates the shielded section and the waterproof section, can suppress the above-mentioned risk of water or the like infiltrating from the outside of the vehicle compartment R2 into the inside of the vehicle compartment R1.

[0034] As described above, the wiring structure 100 of the wire harness 1 according to the present embodiment and the wire harness 1 are reduced in cost and have excellent watertightness.

[0035] However, it is preferable that the interior of the vehicle R1 is surrounded by a panel P made of a metal plate or the like, and that no electronic devices or the like that may cause malfunctions due to noise are installed inside the interior of the vehicle R1.

[0036] As a further effect, in the wiring structure 100 of the wire harness 1, the fixing member 40 is fixed to a surface different from the panel P, thereby reducing the load applied to the exposed portions of the electric wires 10 between the fixing member 40 and the grommet 60. Specifically, when the mounting surface of the fixing member 40 and the surface of the panel P having the opening are different surfaces, the bending rate of the exposed portions of the electric wires 10 is smaller than when the mounting surface of the fixing member 40 and the surface of the panel P having the opening are the same surface, and therefore the load applied to the exposed portions of the electric wires 10 can be reduced.

[0037] <Other forms> The present invention is not limited to the above-described embodiments, and can be appropriately modified, improved, etc. Furthermore, the material, shape, size, number, location, etc. of each component in the above-described embodiments are arbitrary and not limited as long as they can achieve the present invention.
