[0022] [Description of embodiments of this disclosure]

[0023] The embodiments of this disclosure are first described by listing them.

[0024] The connection structure of the storage component and the protective component disclosed herein is as follows.

[0025] (1) The connection structure of the receiving member and the protective tube includes: a linear conveying member; a receiving member that receives a first part which is part of the linear conveying member; a protective tube that covers a second part which is another part of the linear conveying member; and an opposite receiving member that receives a third part of the linear conveying member located on the opposite side of the first part, separated by the second part, wherein the protective tube is formed to reach the length of both the receiving member and the opposite receiving member.

[0026] Because the protective tube is shaped to reach both the receiving component and the opposite receiving component in terms of length, it can prevent the linear conveying component from being exposed to the outside. In addition, it is easy to maintain the connection between the protective tube and the receiving component and the opposite receiving component.

[0027] (2) Alternatively, the receiving component may include a receiving main body for receiving the first part and an extension protruding from the receiving main body toward the second part, wherein the end of the protective tube overlaps with the extension in the extending direction of the linear conveying component. Because the end of the protective tube overlaps with the extension in the extending direction of the linear conveying component, the linear conveying component is less likely to be exposed to the outside.

[0028] (3) Alternatively, the end of the protective tube may be attached to the extension. The thickness of the connection between the protective tube and the extension can be adjusted to the thickness of the protective tube, thus miniaturizing the connection structure between the housing component and the protective tube.

[0029] (4) Alternatively, a mark may be provided on the extension portion, indicating the appropriate position of the end of the protective tube that covers the extension portion. Because the protective tube covers the extension portion, the end of the protective tube can be visually observed. The positional relationship between the end of the protective tube and the mark can be used as a standard to confirm whether the protective tube is properly covering the extension portion.

[0030] (5) Alternatively, the boundary between the main body and the extension can be the mark. By confirming whether the protective tube reaches the boundary between the main body and the extension, or the positional relationship between the end of the protective tube and the boundary, it can be confirmed whether the protective tube properly covers the extension.

[0031] (6) Alternatively, the end of the protective tube can be inserted into the extension. This allows the end of the protective tube to be protected within the extension.

[0032] [Details of the embodiments of this disclosure]

[0033] The following is a reference to the appendix. Figure 1 Specific examples of the connection structures between the receiving and protective components in this disclosure are described below. Furthermore, the invention is not limited to these examples, but is intended to include all modifications within the meaning and scope equivalent to the claims, as shown by the claims.

[0034] [Implementation Method]

[0035] The connection structure between the storage component and the protective component in Embodiment 1 will be described below. Figure 1 This is a schematic top view showing the connection structure 10 of the housing member and the protective member. The connection structure 10 of the housing member and the protective member includes a linear conveying member 20, a housing member 30, a protective tube 40, and connector covers 52A and 52B. Connector covers 52A and 52B are examples of housing members on opposite sides.

[0036] The linear transmission component 20 can be any linear component that transmits electricity or light. For example, the linear transmission component can be a general electrical wire with a core wire and a sheath around the core wire, or it can be a bare conductor, shielded wire, stranded wire, enameled wire, nickel-chromium heat-resistant alloy wire, optical fiber, etc. As a linear transmission component for transmitting electricity, it can also be various signal lines and various power lines. In addition, the linear transmission component can be a single linear object or a composite of multiple linear objects (stranded wire, cable that combines multiple linear objects and covers them with a sheath, etc.).

[0037] Here, the linear transmission member 20 is described as an example of an electric wire 20. The electric wire 20 is a wiring member that electrically connects electrical components to each other in a vehicle. Here, multiple electric wires 20 are bundled together in a manner corresponding to the wiring path in the vehicle. Therefore, it is also possible to understand this connection structure 10 as part of a wire harness including multiple electric wires. Here, the multiple electric wires 20 branch and are bundled. Furthermore, in each figure, the multiple electric wires 20 are illustrated in a bundled form. In this embodiment, the multiple electric wires 20 extend in three directions, more specifically, they are bundled in a T-shaped branching manner. In this embodiment, the branch portion of the multiple electric wires 20 is the first portion 21, and the two portions extending from the first portion 21 are the second portions 22A and 22B. Additionally, a third portion 23A and 23B exists on the side of the electric wire 20 opposite to the first portion 21, separated by the second portions 22A and 22B. Here, the third portions 23A and 23B are the ends of the electric wire 20.

[0038] The storage member 30 is a member that houses the first part 21, which is part of the wire 20. Here, the storage member 30 houses the branching portion as the first part 21 of the multiple wires 20. That is, the storage member 30 maintains the branching portions of the multiple wires 20 in a certain branching shape. The storage member 30 can also be a water-stopping member that inhibits the flow of water along the wires 20.

[0039] The storage component 30 may also be a resin component molded with the first part 21 of the wire 20 as an insert. The storage component 30 may also be a component consisting of a pair of box-shaped resin components, which can store the first part 21 of the wire 20.

[0040] The protective tube 40 is a tubular member that covers the second portions 22A and 22B, which are other parts of the wire 20. Here, it is assumed that the protective tube 40 is a corrugated tube with alternating large-diameter portions 42 and small-diameter portions 44. A recess 42g with an opening on the inner circumference is formed inside the large-diameter portion 42 of the inner circumference of the protective tube 40. The recess 42g is formed along the entire circumference of the large-diameter portion 42, and therefore is an annular recess 42g formed along the circumference of the protective tube 40. Such annular recesses 42g include the ends of the protective tube 40, and a plurality of such recesses are formed at intervals along the entire length of the protective tube 40. The protective tube 40 may also be a tube shape with continuous portions of the same shape.

[0041] Connectors 50A and 50B are connected to the ends of the wire 20. Connector covers 52A and 52B are placed on the base ends of the connectors 50A and 50B. That is, a terminal is connected to the end of the wire 20, and the terminal is held within the cavity formed in the connectors 50A and 50B. The wire 20 extends outward from the base ends of the connectors 50A and 50B. The connector cover 52A is an example of a receiving member on the opposite side because it covers the third part 23A of the wire 20, including the portion inside the connector 50A and the portion extending from the base end side of the connector 50A. Similarly, the connector cover 52B is an example of a receiving member on the opposite side because it covers the third part 23B of the wire 20, including the portion inside the connector 50B and the portion extending from the base end side of the connector 50B.

[0042] The aforementioned housing member 30 houses the first part 21 of the wire 20, the protective tube 40 covers the second parts 22A and 22B of the wire 20, and the connector covers 52A and 52B house the third parts 23A and 23B of the wire 20. In this case, to protect the wire 20, the housing member 30 and the protective tube 40 preferably cover the wire 20 without exposing it between them. Furthermore, the connector covers 52A and 52B and the protective tube 40 preferably cover the wire 20 without exposing it between them. Therefore, the following structure is adopted in the connection structure 10 of this housing member and protective tube.

[0043] Figure 2 This is a partially exploded view of the connection structure 10 between the storage component and the protective tube. Figure 3 yes Figure 1 A partial sectional view.

[0044] like Figures 1-3 As shown, the protective tube 40 is formed with a length that reaches both the housing member 30 and the connector covers 52A and 52B. Here, "the protective tube 40 reaching the housing member 30" means that the end of the protective tube 40 contacts the housing member 30, or overlaps at least a portion of the housing member 30 in the extension direction of the wire 20. This prevents the wire 20 from being exposed between the protective tube 40 and the housing member 30. Similarly, "the protective tube 40 reaching the connector covers 52A and 52B" means that the end of the protective tube 40 contacts the connector covers 52A and 52B, or overlaps at least a portion of the connector covers 52A and 52B in the extension direction of the wire 20. This also prevents the wire 20 from being exposed between the protective tube 40 and the connector covers 52A and 52B.

[0045] In this embodiment, the storage component 30 includes a storage main body 32 and extensions 34A and 34B.

[0046] The main body 32 houses the first portion 21 of the wires 20. Here, the main body 32 houses the first portion 21, which serves as a branch portion of the multiple wires 20. The main body 32 maintains and protects the branch shape of the multiple wires 20. More specifically, the main body 32 is formed in a cuboid shape. The main body 32 does not necessarily have to be cuboid; it can have other shapes. For example, the main body can be a shape with a recessed cuboid portion, a shape with a protrusion, or a shape combining planar and curved surfaces. The multiple wires 20 are guided into the main body 32 from one side. The first portion 21, which serves as a branch portion of the multiple wires 20, is housed within the main body 32. Second portions 22A and 22B, which branch and extend from the first portion 21, extend outward from the other sides of the main body 32 and their adjacent sides.

[0047] Extensions 34A and 34B are formed to protrude from the receiving main body 32 toward the second portions 22A and 22B of the wire 20. Here, extension 34A is formed as a cylindrical shape protruding from the side of the receiving main body 32. The portion of the first portion 21 of the wire 20 extending from the side of the receiving main body 32 is housed in extension 34A. The second portion 22A extends outward from the top end of extension 34A. Extension 34B is formed as a cylindrical shape protruding from the other side of the receiving main body 32. The portion of the first portion 21 of the wire 20 extending from the other side of the receiving main body 32 is housed in extension 34B. The second portion 22B extends outward from the top end of extension 34B. Extensions 34A and 34B may also be formed as rectangular tubes.

[0048] When assuming that the housing member 30 is an example of a resin component in which the first part 21 is molded as an insert, it is assumed that the extensions 34A and 34B are resin components in which the first part 21 is molded as an insert together with the housing body 32. It is also assumed that the housing member 30 is an example of a component comprising a pair of box-shaped resin components capable of housing the first part 21. In this case, it can be assumed that the extensions 34A and 34B are semi-cylindrical portions divided together with the housing body 32, and these semi-cylindrical portions are assembled in a manner that clamps the first part 21.

[0049] The extensions 34A and 34B are formed to be of a thickness that can be inserted into the end of the protective tube 40. Here, the outer diameter of the main body of the extensions 34A and 34B is set to be smaller than the inner diameter of the protective tube 40.

[0050] The connector cover 52A is a component that houses the main body 53A and the extension 54A, and is, for example, a component molded from resin. The connector cover 220 can be a component formed integrally by molding, or a component that combines a pair of box-shaped resin components. The connector cover 52A can also be formed from an elastic component such as rubber.

[0051] The housing body 53A covers the rear end of the connector 50A, and together with the connector 50A, houses the third portion 23A, which serves as the end of the wire 20. The extension portion 54A is a cylindrical portion extending from the base end of the housing body 53A, and houses the third portion 23A of the wire 20 that extends from the base end of the housing body 53A. The portion of the wire 20 between the aforementioned extension portion 54A and the extension portion 34A is the second portion 22A.

[0052] The connector cover 52B is a component comprising a housing body 53B and a retaining part 54B, and is, for example, a component molded from resin. The connector cover 220 can be a component integrally formed by molding, or a component consisting of a pair of box-shaped resin components. The connector cover 52B can also be formed from an elastic component such as rubber.

[0053] The housing body 53B covers the rear end of the connector 50B, and together with the connector 50B, houses the third portion 23B, which serves as the end of the wire 20. The retaining portion 54B is a cylindrical portion extending from the base end of the housing body 53B. The retaining portion 54B is shaped to house the other end of the protective tube 40, and a tube positioning protrusion 55B is formed on its inner circumference, which is inserted into the annular recess at the other end of the protective tube 40. The retaining portion 54B houses the third portion 23B of the wire 20 extending from the base end of the housing body 53B, together with the other end of the protective tube 40. Regarding the connector cover 52B, as a two-part structure, it can also be formed as a combined structure that clamps and fixes the connector 50B and the other end of the protective tube 40. The portion between the aforementioned extension 34B and the retaining portion 54B in the wire 20 is the second portion 22B.

[0054] Between the housing member 30 and the connector cover 52A, a protective tube 40 is formed with a length that reaches both the housing member 30 and the connector cover 52A. Here, one end of the protective tube 40 contacts the housing body 32, covering the extension 34A. One end of the protective tube 40 overlaps with the extension 34A, which is an element of the housing member 30, in the extension direction of the wire 20, so the protective tube 40 reaches the housing member 30. Furthermore, the other end of the protective tube 40 contacts the housing body 53A, covering the extension 54A. The other end of the protective tube 40 overlaps with the extension 54A, which is an element of the connector cover 52A, in the extension direction of the wire 20, so the protective tube 40 reaches the connector cover 52A.

[0055] The length L of the protective tube 40 is studied in relation to the distances between the various parts. Preferably, the length L of the protective tube 40 exceeds the distance D1 between the extension portions 34A and 54A. Furthermore, the length L of the protective tube 40 is preferably greater than the longer of the distance D2 between the extension portion 34A and the receiving body portion 53A, and the distance D3 between the receiving body portion 32 and the extension portion 54A, in the direction of wire 20 extension. This makes it easier for the protective tube 40 to remain in a state covering the extension portions 34A and 54A. For example, the length L of the protective tube 40 can also be set to be the same as the distance D3 between the receiving body portion 32 and the receiving body portion 53A. Again, the length L of the protective tube 40 is preferably greater than the distance D in the direction of wire 20 extension than the distance D between the receiving body portion 32 and the receiving body portion 53A. In this case, the protective tube 40 is disposed in a compressed state between the receiving body portion 32 and the receiving body portion 53A.

[0056] Between the housing member 30 and the connector cover 52B, a protective tube 40 is formed with a length that reaches both the housing member 30 and the connector cover 52B. Here, one end of the protective tube 40 contacts the housing body 32, covering the extension portion 34B. Because one end of the protective tube 40 overlaps with the extension portion 34B, which is an element of the housing member 30, in the extension direction of the wire 20, the protective tube 40 reaches the housing member 30. Furthermore, the other end of the protective tube 40 is held within the retaining portion 54B. Because the other end of the protective tube 40 overlaps with the retaining portion 54B, which is an element of the connector cover 52B, in the extension direction of the wire 20, the protective tube 40 reaches the connector cover 52B.

[0057] In other words, the other end of the protective tube 40 is held in a position where it is positioned by the retaining part 54B. Based on the position where the other end of the protective tube 40 is positioned by the retaining part 54B, the length L1 of the protective tube 40 is set to exceed the position P1 of the top end of the extension part 34B and reach the position P2 of the receiving member 30. The protective tube 40 can be set to a length where one end connects to the receiving member 30, or it can be set to a length where that end covers the extension part 34B. Similarly, the length L1 of the protective tube 40 can also be a compressed size between the receiving member 30 and the connector cover 52B.

[0058] According to the connection structure 10 of the housing member and the protective tube, the protective tube 40 is formed to reach the length of the housing member 30 and the connector covers 52A, 52B, which are housing members on the opposite side. Therefore, the wire 20 can be prevented from being exposed to the outside from between the housing member 30 and the protective tube 40 or between the connector covers 52A, 52B and the protective tube 40.

[0059] Furthermore, by setting the distance between the housing member 30 and the connector covers 52A, 52B, and the length of the protective tube 40, the connection between the protective tube 40 and the housing member 30 or the connector covers 52A, 52B can be maintained. Therefore, special structures for connecting the protective tube 40 to the housing member 30 or the connector covers 52A, 52B, such as hook structures, fastening structures, or winding fixing structures, can be omitted, and the connection can be maintained with a simple structure.

[0060] In addition, because the end of the protective tube 40 overlaps with the extensions 34A, 34B, 54A and the retaining part 54B, gaps are less likely to occur between the protective tube 40 and the housing member 30, connector covers 52A, 52B, etc., and the wire 20 is less likely to be exposed to the outside.

[0061] Furthermore, because the end of the protective tube 40 covers the extensions 34A, 34B, and 54A, the thickness of the connection between the protective tube 40 and the extensions 34A, 34B, and 54A becomes the same as that of the protective tube 40. Therefore, this connection structure 10 is miniaturized. Additionally, since the protective tube 40 covers the extensions 34A, 34B, and 54A, the end of the protective tube 40 can be visually seen from the outside. Therefore, it is easy to determine the extent to which the protective tube 40 covers the extensions 34A, 34B, and 54A.

[0062] [Variation Example]

[0063] Various variations will be described based on the above embodiments.

[0064] Figure 4This is a partially enlarged view showing the first modified example. In this modified example, a mark 136A is provided on the extension 34A, indicating the appropriate position of the protective tube 40 covering the extension 34A. Here, a protrusion that annularly protrudes from the main body of the extension 34A is formed at the base end of the extension 34A. The step on the top side of this protrusion is marked 136A.

[0065] When placing the protective tube 40 onto the extension 34A, visually confirm the relative positional relationship between the end of the protective tube 40 and the mark 136A, ensuring that the end of the protective tube 40 extends beyond the mark 136A. This confirms that the protective tube 40 is securely attached to the extension 34A. In other words, because the protective tube 40 is attached to the extension 34A, the end of the protective tube 40 can be visually confirmed. Furthermore, using the positional relationship between the end of the protective tube 40 and the mark 136A as a standard, it can be confirmed that the protective tube 40 is properly attached to the extension 34A.

[0066] In this modified example, a protrusion is formed in the extension 34A, and a mark 136A is formed through the step of the protrusion. In the first embodiment described above, the boundary between the housing body 32 and the extension 34A can also be used as the mark 36A. By checking the positional relationship between the end of the protective tube 40 and the mark 36A, it can be determined whether the protective tube 40 properly covers the extension 34A. For example, if the end of the protective tube 40 reaches the mark 36A, that is, if it contacts the housing body 32, it can also be determined that the protective tube 40 properly covers the extension 34A. Furthermore, if the distance between the end of the protective tube 40 and the mark 36A is a predetermined size or less, it can also be determined that the protective tube 40 properly covers the extension 34A.

[0067] Figure 5 This is a partially enlarged cross-sectional view showing the second modified example. In this modified example, a positioning protrusion 235A is formed in the extension 34A, and the positioning protrusion 235A is embedded in the annular recess 42g of the protective tube 40. Here, the positioning protrusion 235A is formed as an annular protrusion shape protruding circumferentially along the extensions 34A and 34B, and is formed between the top end and the base end of the extension 34A. The outer diameter of the positioning protrusion 235A is larger than the minimum inner diameter of the protective tube 40, and is the same as or smaller than the inner diameter of the annular recess 42g. In addition, the thickness of the positioning protrusion 235A is the same as or smaller than the width of the annular recess 42g (the width in the direction along the axial direction of the protective tube 40). As a modified example of the positioning protrusion 235A, an inclined surface 235g may also be provided (see reference). Figure 5(The double-dotted line). The inclined surface 235g is a part used to facilitate the external insertion of the protective tube 40. For example, the inclined surface 235g can be formed on the outer surface of the positioning protrusion 235A in a manner that slopes inward toward the top end of the extension 34A. Thus, when the protective tube 40 is externally inserted into the extension 34A, the protective tube 40 contacts the inclined surface 235g and is smoothly guided toward the base end of the extension 34A. Thus, the protective tube 40 is easily externally inserted into the extension 34A. In addition, when the protective tube 40 is placed on the extension 34A, the base end portion of the extension 34A in the positioning protrusion 235A is embedded in the annular recess 42g, so the protective tube 40 is not easily dislodged from the extension 34A.

[0068] Furthermore, the end of the protective tube 40 is covered onto the extension portion 34A by pressing the extension portion 34A into the end of the protective tube 40, and the positioning protrusion 235A is embedded into the annular recess 42g at the end of the protective tube 40. As a result, the protective tube 40 is not easily detached from the extension portion 34A.

[0069] Figure 6 This is a partially enlarged cross-sectional view showing the third modified example. In this modified example, an extension portion 334A is provided instead of an extension portion 34A. The inner diameter of the extension portion 334A is set to be larger than the outer diameter of the protective tube 40. Therefore, the end of the protective tube 40 can be inserted into the extension portion 334A.

[0070] In this example, one end of the protective tube 40, when inserted into the extension 334A, reaches the receiving member 330 including the extension 334A. As described above, the protective tube 40 is formed to reach the length of the receiving member 330 and the connector cover 52A, so the end of the protective tube 40 is not easily detached from the extension 334A, and the wire 20 is not easily exposed to the outside between the protective tube 40 and the receiving member 330.

[0071] According to this modified example, since the end of the protective tube 40 is inserted into the extension portion 334A, the end of the protective tube 40 can be protected within the extension portion 334A. Furthermore, as described above, by setting the length of the protective tube 40, a structure can be ensured that the protective tube 40 will not easily detach from the extension portion 334A, thus eliminating the need for a structure where the end of the protective tube 40 is hooked onto the extension portion 334A. Additionally, the need to confirm whether the end of the protective tube 40 is fully inserted into the extension portion 334A can also be eliminated.

[0072] Figure 7 This is a partially enlarged cross-sectional view showing the fourth modified example. In this modified example, the extensions 34A and 34B are omitted in the storage member 430 corresponding to the storage member 30 in the above embodiment. Furthermore, the extension 54A is omitted in the connector cover 452A corresponding to the connector cover 52A.

[0073] Even in this case, when the protective tube 40 is set to a length that reaches and contacts the housing member 430 and the connector cover 452A, the wire 20 is unlikely to be exposed between the protective tube 40 and the housing member 430 and the connector cover 452A. Similarly, when the protective tube 40 is set to a length that reaches and contacts the housing member 430 from the connector cover 452B, the wire 20 is also unlikely to be exposed between the protective tube 40 and the housing member 430.

[0074] In the above embodiments, it is not necessary for the receiving member 30 to receive the branch portions of the multiple wires 20. The receiving member can receive either the middle portion of the wire in its extension direction or the end portion of the wire. The same applies in the above variations.

[0075] The connector cover described in the embodiments or variations may also be an integrally formed part with the connector.

[0077] The aforementioned wiring harness WH1 can be installed in a vehicle, for example, as a wiring component connecting the vehicle body 500 and the wheel 510. The wiring harness for the wheel needs to be installed in the narrow space between the wheel arch and the wheel 510. Furthermore, because it is installed around the wheel, the protection requirements are relatively high. In the aforementioned connection structure 10, etc., the wires 20 can be prevented from being exposed between the protective tube 40 and the housing member 30, etc., and the connection structure 10 can be miniaturized. Therefore, it is suitable for use as the wiring harness WH1 connecting the vehicle body 500 and the wheel 510.

[0078] Furthermore, the aforementioned wiring harness WH2, for example, is located further forward than the vehicle compartment in a vehicle, and can be installed in the vehicle as a wiring component disposed in a space S separated from the outside. This space S is called the engine compartment in vehicles equipped with internal combustion engines, and sometimes the space where an electric motor is located in electric vehicles. Such a space S can also be understood as a space where power generators such as internal combustion engines and electric motors are disposed. Since the space S is an environment prone to vibration due to internal combustion engines and electric motors, vibration is also applied to the wiring components disposed in the space S.

[0079] The length of the protective tube 40 is set to reach the housing member 30 and the connector covers 52A and 52B. Therefore, when the wire harness WH2, including the connecting structure 10, is disposed in the aforementioned space S, the protective tube 40 can easily maintain its position relative to the housing member 30 and the connector covers 52A and 52B, even under vibration. In particular, the ends of the protective tube 40 overlap with the extension portions 34A, 34B, 54A and the retaining portion 54B. Therefore, even if the wire harness WH2 vibrates, the protective tube 40 covers the extension portions 34A, 34B, and 54A, and correspondingly, even if the protective tube 40 shifts, the exposure of the wire 20 can be suppressed. Therefore, even in a vibration environment, the wire 20 can be adequately protected with a simple structure.

[0080] Furthermore, the structures described in the above embodiments and modifications can be appropriately combined as long as they do not contradict each other. For example, in one end of the protective tube and the other end, a structure in the embodiment where the protective tube overlaps with the extension portion and a structure in the fourth modification where the extension portion is omitted can coexist.

[0081] The invention has been described in detail above; however, the description is illustrative in all respects and the invention is not limited thereto. It will be understood that numerous modifications not illustrated can be conceived without departing from the scope of the invention.
