Description

Technical Field

[0001] The present invention relates to a fixing structure for an optional connector in a wire harness.

Background Art

[0002] Conventionally, wire harnesses have been laid in every corner of a vehicle, such as in an engine room, inside a door, or inside a room, for the purpose of supplying power to electrical components and transmitting signals. Some wire harnesses include optional connectors for equipment (optional parts) that are optionally installed in the vehicle. In such a wire harness, for example, some wires branch off from a main line formed by bundling a large number of wires as branch lines, and an optional connector is connected to the end of each branch line.

[0003] The number of branch lines and optional connectors varies depending on the number of parts required according to the type of vehicle and optional equipment. However, in order to improve the efficiency of manufacturing and management of wire harnesses, it has become common to minimize the types (part numbers) of wire harnesses and standardize them. In this case, the wire harness is provided with the number of branch lines and optional connectors corresponding to a vehicle with a large number of parts, and an operator selectively uses the necessary connectors during vehicle assembly. Therefore, in the case of a vehicle with a small number of parts, there are branch lines and optional connectors that are not used during assembly. If this optional connector contacts the vehicle body or other parts during driving vibration or the like, problems such as damage to the vehicle body or other parts or generation of abnormal noises may occur.

[0004] As a countermeasure, an adhesive tape is wound in one direction along the main line of the wire harness with an optional connector attached, and the optional connector is fixed to the main line of the wire harness. When an operator selectively uses the necessary optional connector, the optional connector to be selectively used is removed from the adhesive tape (see, for example, Patent Document 1).

[0005] [Patent Document 1] Japanese Patent Publication No. 2016-13004 [Overview of the project] [Problems that the invention aims to solve]

[0006] However, as mentioned above, the wire harness with the optional connectors fixed to the main wire is assembled at a separate location such as a parts manufacturer, compactly rolled up and packaged, and then transported to the vehicle assembly site. However, there is a concern that during transport before assembly to the vehicle, the optional connectors may come loose from the adhesive tape and detach from the main wire of the wire harness.

[0007] The object of the present invention is to provide a fixing structure that makes it difficult for a discarded optional connector, which is connected to a branch wire that has branched off from the main wire of a wire harness, to come loose from the main wire. [Means for solving the problem]

[0008] To achieve the above objective, the fixing structure according to the present invention is a fixing structure for fixing an optional connector connected to a branch line branched from the main line of a wire harness to the main line, wherein the fixing member having a band portion and a clamp portion for fixing the wire harness to a vehicle on which the wire harness is laid has the band portion wrapped around the main line, The aforementioned The present invention is characterized by comprising: a first adhesive tape wrapped around one side of the main line in the direction of extension of the main line with respect to the band portion; and a second adhesive tape located on one side of the direction of extension of the main line with respect to the band portion on the side of the optional connector opposite to the side of the main line facing the main line, and located on the other side of the direction of extension of the main line with respect to the band portion on the side of the main line where the clamp portion exists, and wrapped around the band portion with a winding axis in a different direction from the first adhesive tape, straddling the band portion.

[0009] According to this configuration, Even if the second adhesive tape tries to shift to one side of the main wire (the side with the first adhesive tape) due to vibrations in the direction of extension of the vehicle's wire harness main wire, the second adhesive tape can catch on the fixing member and prevent it from shifting to one side of the main wire (the side with the first adhesive tape), thereby making it less likely for the optional connector to come off the first adhesive tape and detach from the main wire.

[0010] Furthermore, a fixing structure for fixing an optional connector connected to a branch line branched from the main line of a wire harness to the main line, comprising: a first adhesive tape wrapped around the outer circumference of the main line and the optional connector, viewed as a whole with the optional connector along the main line, on a first winding axis parallel to the extending direction of the main line; and the main line, the optional connector, and the outer circumference of the first adhesive tape, viewed as a whole with the first adhesive tape wrapped around them, axis and The device comprises a second adhesive tape wound around a second winding axis in a different direction, wherein the second adhesive tape partially overlaps with the first adhesive tape in the portion wound around the outer circumference of the optional connector, and is wound at an angle to the first adhesive tape in a side view. With the band portion of a fixing member having a band portion and a clamp portion for fixing the wire harness to the vehicle on which the wire harness is laid wrapped around the main wire, the first adhesive tape is wrapped around the first winding shaft on one side of the main wire in the direction of extension with respect to the band portion, and the second adhesive tape is located on one side of the main wire in the direction of extension with respect to the band portion on the side of the optional connector opposite to the side facing the main wire, and on the other side of the main wire in the direction of extension with respect to the band portion on the side of the main wire where the clamp portion is located, and is wrapped around the second winding shaft so as to straddle the band portion. It would be good to do so. In this configuration, the first adhesive tape is wrapped around the outer circumference of the main wire and optional connector, viewed as a whole, with a first winding axis having a first angle parallel to the direction of extension of the main wire. The second adhesive tape is wrapped around the outer circumference of the main wire, optional connector, and first adhesive tape, viewed as a whole, with a second winding axis in a different direction from the first winding axis. The portion of the first adhesive tape wrapped around the outer circumference of the optional connector overlaps with the first adhesive tape, and in a side view, the second adhesive tape is wrapped at an angle to the first adhesive tape. As a result, even if the vehicle vibrates in the direction of extension of the main wire harness, the second adhesive tape prevents the first adhesive tape from shifting relative to the optional connector, thereby making it less likely for the optional connector to come off the first adhesive tape and detach from the main wire. Furthermore, the second adhesive tape is wrapped around a first winding axis that is parallel to the direction of extension of the main line, and the first adhesive tape is wrapped around it. Those who By winding it on the second winding shaft in the opposite direction, the optional connector will not come off during normal operation, and the optional connector will be straight. stretchWhen the wire harness is pulled along the direction of extension of the main wire, the portion of the second adhesive tape attached to the optional connector is pulled in conjunction with the optional connector, causing the portion of the second adhesive tape near the boundary between the main wire of the wire harness and the optional connector to bend outwards, becoming more perpendicular to the direction of extension of the main wire. This outward bending of the second adhesive tape makes it easier to move the optional connector away from the main wire of the wire harness, thus facilitating the removal of the optional connector from the main wire of the wire harness by the worker.

[0012] Also Even if the second adhesive tape tries to shift to one side of the main wire (the side with the first adhesive tape) due to vibrations in the direction of extension of the vehicle's wire harness main wire, the second adhesive tape can be prevented from shifting to one side of the main wire (the side with the first adhesive tape) by catching on the fixing member, thereby preventing the optional connector from coming off the first adhesive tape and moving away from the main wire. Miss It can be made more difficult. [Effects of the Invention]

[0013] According to the present invention, the first adhesive tape is wrapped around the outer circumference of the main wire and optional connector, viewed as a whole, using a first winding shaft with a first angle that is approximately 0 degrees with respect to the direction of extension of the main wire. The second adhesive tape is wrapped around the outer circumference of the main wire, optional connector, and first adhesive tape, viewed as a whole, using a second winding shaft with a second angle that is different from the first angle that is respect to the direction of extension of the main wire, so as to overlap with the first adhesive tape at the portion of the optional connector. As a result, even if the vehicle vibrates in the direction of extension of the main wire of the wire harness, the second adhesive tape can prevent the first adhesive tape from shifting relative to the optional connector, thereby making it less likely for the optional connector to come off the first adhesive tape and detach from the main wire.

[0014] Furthermore, by wrapping the second adhesive tape around a second winding shaft that has a different angle from the first winding shaft that has a first angle, which has an angle with respect to the direction of extension of the main wire, the optional connector is prevented from coming off under normal conditions. When the optional connector is pulled along the direction of extension of the main wire of the straightened wire harness, the portion of the second adhesive tape attached to the optional connector is pulled in conjunction with the optional connector, causing the portion of the second adhesive tape near the boundary between the main wire of the wire harness and the optional connector to bend outwards, becoming closer to perpendicular to the direction of extension of the main wire. This outward bending of the second adhesive tape makes it easier to move the optional connector away from the main wire of the wire harness, thus facilitating the removal of the optional connector from the main wire of the wire harness by the worker. [Brief explanation of the drawing]

[0015] [Figure 1] This figure schematically shows the fixing structure of an optional connector (disposable connector) for a wire harness in a disposable state according to one embodiment of the present invention, where (a) is a top view showing a disposable connector connected to the end of a branch wire of the wire harness fixed to the main wire of the wire harness, and (b) is a side view of the same state. [Modes for carrying out the invention]

[0016] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0017] The configuration of the fixing structure 1 for fixing an optional connector C to the main line H1 of a wire harness H according to one embodiment of the present invention will be described with reference to Figure 1.

[0018] The structure of the wire harness H and the like are generally known. In this embodiment, a wire harness with a generally known structure is used as the wire harness H, and details of the structure of the wire harness H and the like are omitted.

[0019] The wire harness H is laid in every corner of the vehicle, such as in the engine room, inside the door, and inside the room, for the purpose of supplying power and transmitting signals to electrical components and the like. It includes a main line H1 formed by bundling a large number of electric wires, and a plurality of branch lines such as a branch line H2 from which some electric wires are branched and drawn out from the main line H1. At the end of the branch line H2, an optional connector C, which is a female connector for example, is connected, and at the end of each branch line, an optional connector, which is a female connector, is connected.

[0020] In this embodiment, it is assumed that the number of branch lines and optional connectors including the branch line H2 and the optional connector C is more than the necessary number according to the type of vehicle in which the wire harness H is laid, the number of parts such as optional equipment, and the like. In this case, some of the plurality of optional connectors are fitted to connectors (component-side connectors) such as male connectors on the corresponding component side to be used for mounting the corresponding component to the wire harness H, while the remaining optional connectors are not fitted to connectors (component-side connectors) such as male connectors on the component side and are not used. The optional connector C in FIG. 1 is an optional connector in a disposable state (hereinafter, referred to as a "disposable connector"). In this embodiment, it corresponds to one of the remaining optional connectors. In the following description, the "optional connector C" is described as the "disposable connector C" as appropriate.

[0021] The wire harness H is fixed to the vehicle using the band clamp 10 in a state where it is laid in the vehicle. The band clamp 10 includes a band-shaped band portion 11, a band lock portion 12 provided at the rear end of the band portion 11 and having a through hole 12a formed therein, a frustum-shaped base portion 13 formed on the surface of the band lock portion 12 opposite to the surface where the band portion 11 is present, and a clamp portion 14 protruding from the surface of the base portion 13 opposite to the surface where the band lock portion 12 is present. Note that the band clamp 10 corresponds to the "fixing member" of the present invention, the band portion 11 corresponds to the "band portion" of the present invention, and the clamp portion 14 corresponds to the "clamp portion" of the present invention. <0000,094><0000,095><0000,096>As shown in FIG. 1, the band portion 11 is wound around the outer periphery of the main line H1 of the wire harness H, and its tip is inserted from one side of the through hole 12a formed in the band lock portion 12 and pulled out from the other side to tighten the main line H1, so that the main line H1 and the band clamp 10 do not move relative to each other. <0000,097><0000,098><0000,099>The adhesive tapes T1 to T3 are strip-shaped tapes having an adhesive applied on one surface. <0000,100><OO00,101><0000,102>As shown in FIG. 1, the adhesive tape T1 is wound around the outer periphery of the main line H1 at the tip where the branch line H2 branches from the main line H1, and further, the branch line H2 whose extending direction is bent by approximately 180 degrees is placed along the main line H1. In this state, when the main line H1 and the branch line H2 are viewed as a unit, it is wound around the outer periphery of the main line H1 and the branch line H2 viewed as a unit. Naturally, the adhesive tape T1 is wound so that the surface coated with the adhesive faces inward. <0000,103><0000,104><0000,105>With the main wire H1 tightened by the band portion 11 of the band clamp 10, as shown in Figure 1, the disposable connector C is positioned along the main wire H1 on the side of the main wire H1 opposite to the side facing the band lock portion 12, such that when viewed from above, a part of the disposable connector C overlaps with the band portion 11. In this embodiment, when the disposable connector C is positioned along the main wire H1, the direction from the insertion side of the branch wire H2 of the disposable connector C (hereinafter referred to as the "insertion side") to the terminal side (hereinafter referred to as the "terminal side") is the axial direction of the main wire H1 (the direction in which the main wire H1 extends), so that the disposable connector C is positioned along the main wire H1.

[0026] As shown in Figure 1, with the disposable connector C aligned along the main line H1, and the main line H1 and disposable connector C viewed as a single unit, the adhesive tape T2 is wrapped around the outer circumference of one side of the main line H1 in the direction of extension of the main line H1 (the side with the terminal surface of the disposable connector C), with the band portion 11 as the reference point, using a first angle that makes approximately 0 degrees with respect to the direction of extension of the main line H1 (the axial direction of the main line H1) as the winding axis (hereinafter referred to as the "first winding axis"). (The tape is wrapped in a direction perpendicular to the axial direction of the main line H1, i.e., along the outer circumference of the main line H1). Naturally, the adhesive tape T2 is wrapped so that the side with the adhesive applied faces inward. Note that the adhesive tape T2 corresponds to the "first adhesive tape" of the present invention, the first angle corresponds to the "first angle" of the present invention, and the first winding axis corresponds to the "first winding axis" of the present invention.

[0027] The disposable connector C has a shape in which a portion of the terminal side (the portion indicated by arrow a in Figure 1(b)) is cut off, and in this embodiment, the adhesive tape T2 is wrapped around it so as to include the cut portion. Therefore, unless countermeasures are taken, the disposable connector C is likely to come off the adhesive tape T2 due to vehicle vibrations, etc.

[0028] As shown in Figure 1, with adhesive tape T2 wrapped around the outer circumference of the main line H1 and the disposable connector C, the main line H1, the disposable connector C, and the adhesive tape T2 are viewed as a single unit. The adhesive tape T3 is wrapped around an axis (hereinafter referred to as the "second winding axis") whose angle with respect to the extending direction of the main line H1 (axial direction of the main line H1) is different from the first angle. When wrapping adhesive tape T3 around the second winding axis, adhesive tape T3 overlaps with adhesive tape T2 in part of the portion where adhesive tape T2 wraps around the disposable connector C. Furthermore, when wrapping the adhesive tape T3 around the second winding shaft, on the side of the disposable connector C opposite to the side facing the main line H1 (the side opposite to the side where the band lock portion 12, base portion 13, and clamp portion 14 of the band clamp 10 exist, relative to the axis of the main line H1), it is positioned on one side in the extending direction of the main line H1 relative to the band portion 11 (the side where the terminal surface of the disposable connector C is located, relative to the band portion 11). On the side of the main line H1 where the band lock portion 12, base portion 13, and clamp portion 14 of the band clamp 10 exist (the side where the disposable connector C does not exist, relative to the axis of the main line H1), it is positioned on the other side in the extending direction of the main line H1 relative to the band portion 11 (the side where the terminal surface of the disposable connector C is not located, relative to the band portion 11, i.e., the side where the insertion surface of the disposable connector C is located, relative to the band portion 11), so as to straddle the band portion 11. Naturally, the adhesive tape T3 is wrapped so that the side with the adhesive applied faces inward. Note that the adhesive tape T3 corresponds to the "second adhesive tape" of the present invention, the second angle corresponds to the "second angle" of the present invention, and the second winding axis corresponds to the "second winding axis" of the present invention.

[0029] The adhesive tapes T2 and T3 described above form the fixing structure 1.

[0030] With the adhesive tape T3 wrapped diagonally around the main wire H1, the disposable connector C, and the outer circumference of the adhesive tape T2, the clamp portion 14 of the band clamp 10 is fitted into the mounting hole on the vehicle side and secured. As a result, the wire harness H is laid on the vehicle in a state where it is relatively difficult to move relative to the vehicle.

[0031] According to the above embodiment, the adhesive tape T2 is wrapped around the outer circumference of the main wire H1 and the detachable connector C, viewed as a whole, with a first winding shaft having a first angle that is approximately 0 degrees in relation to the direction of extension of the main wire H1. The adhesive tape T3 is wrapped around the outer circumference of the main wire H1, the optional connector C, and the adhesive tape T2, viewed as a whole, with a second winding shaft having a second angle that is different from the first angle in relation to the direction of extension of the main wire H1, so as to overlap with the adhesive tape T2 at the detachable connector C. Therefore, even if the vehicle vibrates in the direction of extension of the main wire H1 of the wire harness H, the adhesive tape T3 can prevent the first adhesive tape from shifting relative to the detachable connector C, thereby making it difficult for the detachable connector C to come off the adhesive tape T2 and detach from the main wire H1.

[0032] Furthermore, by winding the adhesive tape T3 on a second winding axis having a second angle different from the first winding axis having a first angle that is approximately 0 degrees with respect to the direction of extension of the main wire H1, the optional connector C is prevented from coming off under normal conditions. When the disposable connector C is pulled along the direction of extension of the main wire H1 of the straightened wire harness H, the portion of the adhesive tape T3 attached to the disposable connector C is pulled in conjunction with the disposable connector C, causing the portion of the adhesive tape T3 near the boundary between the main wire H1 of the wire harness H and the disposable connector C to bend so as to be nearly perpendicular to the direction of extension of the main wire, causing the adhesive tape T3 to bulge outwards. This outward flexing of the adhesive tape T3 makes it easier to move the disposable connector C in the direction of removal from the main wire H1 of the wire harness H, thus facilitating the removal of the disposable connector C from the main wire H1 of the wire harness H by the worker.

[0033] Furthermore, even if the adhesive tape T3 tries to shift to one side of the main wire H1 (the side with the adhesive tape T2) due to vibrations in the direction of extension of the main wire H1 of the vehicle's wire harness H, the adhesive tape T3 can catch on the band lock portion 12 or base portion 13 of the band clamp 10, preventing it from shifting to one side of the main wire H1 (the side with the adhesive tape T2). This makes it less likely for the disposable connector C to come off the adhesive tape T2 and detach from the main wire H1.

[0034] Furthermore, various design modifications can be made to the aforementioned configuration within the scope of the matters described in the patent claims.

[0035] The present invention is widely applicable to fixing structures for optional connectors in wire harnesses. [Explanation of Symbols]
