Description

  TECHNICAL FIELD The present invention relates to an option connector fixing structure for fixing an option connector provided on a branch line terminal branched from a trunk line of a wire harness routed to an automobile or the like to the trunk line of the wire harness when not in use. .

  Conventionally, a wire harness constructed by bundling a plurality of electric wires or optical cables that are routed to an automobile or the like has a structure in which a number of branch lines are branched from appropriate locations on the main line, and is provided at the end of the branch line. It is designed to be connected to various electrical components etc. via the connectors and the like.

  By the way, for example, even in the same vehicle type, optional electrical components that are selectively attached depending on the grade may be set. In such a case, in a wire harness configured for the same vehicle type, a case may occur in which a so-called optional connector provided on a specific branch line terminal for optional electrical components is unused depending on the grade. Such an unused optional connector needs to be fixed and held on the main line of the wire harness from the viewpoint of interference with other members and prevention of abnormal noise.

  Therefore, conventionally, as shown in FIG. 3 of Japanese Patent Application Laid-Open No. 7-131919 (Patent Document 1), a binding tape such as a vinyl tape is provided around a branch line portion of an optional connector superimposed on a trunk line of a wire harness. A fixing structure that winds and binds is widely adopted. Further, as shown in FIG. 1 of Patent Document 1, a fixing structure has also been proposed in which a branch line portion of an option connector is bound to a trunk line of a wire harness using a binding band.

  However, in such a conventional fixing structure, there is a problem in that work efficiency is poor when an optional connector is used, because it is necessary to cut a vinyl tape or a binding band with a cutting tool such as scissors. In addition, there is a problem that wastes such as broken binding bands and vinyl tape are generated, and the disposal thereof becomes complicated. Furthermore, there is a possibility that such waste (broken fragments) may be mixed into other connectors or various electrical components.

  In addition, at the part where the optional connector is provided, the weight of the wire harness is heavy and easily vibrates when the vehicle travels, and other wire harnesses and parts are often arranged nearby, The generation of collision noise due to contact with other members may be a problem. For this reason, it is necessary to take measures to prevent collision noise by covering the periphery of the main wire of the wire harness provided with the optional connector with a shock-absorbing exterior material, and there is a problem that the number of parts and work man-hours cannot be avoided. It was.

JP-A-7-131919

  The present invention has been made in the background of the above-mentioned circumstances, and the solution is to use an unused optional connector provided on a branch line terminal, a broken piece or a discard member with respect to the trunk line of the wire harness. An optional connector fixing structure with a novel structure that can be easily and stably detachably fixed without causing a collision, and that can also prevent the occurrence of collision noise between the wire harness and other members. There is to do.

  A first aspect of the present invention is a fixing structure for fixing an optional connector provided at a terminal of a branch line branched from a trunk line of a wire harness to the trunk line of the wire harness, and an outer peripheral surface of the trunk line is a hook-and-loop fastener On the other hand, a fixing member made of a hook surface of the hook-and-loop fastener is provided on at least one surface of the branch line and the optional connector, and the fixing member is attached to the covering material of the covering material. The option connector is detachably connected to the main line by adhering to an arbitrary location.

  According to this aspect, the fixing member formed of the hook surface of the hook-and-loop fastener provided on the surface of at least one of the branch line and the optional connector with respect to an arbitrary position of the trunk line covered with the covering material formed of the loop surface of the hook-and-loop fastener By attaching, the optional connector can be detachably connected to the main line. Since the connection between the optional connector and the main line is realized by using the loop surface and hook surface of the hook-and-loop fastener, when using the optional connector, pull the optional connector to release the engagement between the loop surface and the hook surface. The connection can be released simply by doing. Therefore, there is no occurrence of a broken piece, a discard member, or the like, which has been a problem when the conventional tape is bound. In addition, the reconnection can be performed simply by attaching the fixing member to an arbitrary place of the covering material, and the optional connector can be easily and easily attached to / detached from the trunk line without requiring a new process or member. .

  Moreover, even if the loop surface of the hook-and-loop fastener is used as a covering material, the trunk line is covered, so the collision noise between the wire harness and other members can be prevented with a small number of parts, and a simple and stable optional connector The attachment and detachment with respect to the trunk line can be advantageously realized.

  According to a second aspect of the present invention, in the first aspect, an outer peripheral surface of the branch line is covered with the fixing member.

  According to this aspect, since the outer peripheral surface of the branch line is covered with the fixing member made of the hook surface of the hook-and-loop fastener, by using the fixing member without using a special buffer agent, the branch line and the other member Reduction of impact sound and collision sound at the time of interference can be expected. Further, since the fixing member and the covering member can be adhered over a wide range, the optional connector when not in use can be firmly and stably held by the trunk line.

  In the present invention, a fixing member made of a hook surface of a hook-and-loop fastener provided on at least one surface of a branch line and an optional connector with respect to an arbitrary position of the trunk line covered with a covering material made of a loop surface of the hook-and-loop fastener. By attaching, the optional connector can be detachably connected to the main line. Thereby, when using the option connector, the connection can be released simply by pulling the option connector and releasing the engagement between the loop surface and the hook surface. Therefore, there are no broken fragments or discarded members that have been a problem in the conventional structure. In addition, the reconnection can be performed simply by attaching the fixing member to any place of the covering material, and the optional connector can be easily and easily attached to / detached from the trunk line without requiring a new process or member. Moreover, even if the loop surface of the hook-and-loop fastener is used as a covering material, the trunk line is covered, so the collision noise between the wire harness and other members can be prevented with a small number of parts, and a simple and stable optional connector It can be advantageously attached to and detached from the main line.

  Embodiments of the present invention will be described below with reference to the drawings.

  First, FIG. 1 shows an option connector fixing structure 10 as an embodiment of the present invention. In the optional connector fixing structure 10, an optional connector 14 for optional electrical components (not shown) is provided at a terminal of a branch line 12 b branched from a trunk line 12 a of the wire harness 12 in a wire harness 12 routed to an automobile or the like. Applies to what The option connector fixing structure 10 of the present embodiment is a structure for fixing the unused option connector 14 to the main line 12a when the option electrical component is not mounted on the vehicle and the option connector 14 is unused. It is.

  The wire harness 12 is bundled by winding a binding tape 18 or the like around the outer peripheral surface of a large number of electric wire groups 16, and the ends of the trunk line 12a and the branch line 12b are connected to the electric wire groups 16a and 16b. Shaped connectors 14 and 20 are attached.

  Moreover, the outer peripheral surface of the trunk line 12a is a covering material composed of the loop surface 24a of the hook-and-loop fastener 24 over substantially the entire length in the longitudinal direction from the vicinity of the branch portion 22 where the branch line 12b branches from the trunk line 12a to the terminal of the trunk line 12a. It is covered. For example, the covering operation is performed by using a tape-like member in which one surface in the thickness direction is an adhesive surface and the other surface is formed with the loop surface 24a of the surface fastener 24. It can be implemented by winding the side toward the outer peripheral surface of the trunk line 12a.

  On the other hand, the outer peripheral surface of the branch line 12b is covered with a fixing member made of the hook surface 24b of the hook-and-loop fastener 24 in the vicinity of the terminal. For example, such a covering operation is performed by using a tape-like member in which one surface in the thickness direction is an adhesive surface and the other surface is formed with a hook surface 24b of the hook-and-loop fastener 24. It can be carried out by winding the side toward the outer peripheral surface of the branch line 12b.

  Next, a mode in which the option connector 14 is detachably connected to the trunk line 12a of the wire harness 12 using the wire harness 12 according to the option connector fixing structure 10 having the above-described structure will be described in detail below. First, the terminal of the branch line 12b of the wire harness 12 is gripped, and the hook surface 24b of the hook-and-loop fastener 24 provided near the terminal of the branch line 12b is connected to the loop surface 24a of the hook-and-loop fastener 24 provided on the outer peripheral surface of the trunk line 12a. Adhere to any location. Thereby, the loop surface 24a and the hook surface 24b of the hook-and-loop fastener 24 are engaged, and the option connector 14 provided at the end of the branch line 12b is connected to the trunk line 12a of the wire harness 12. On the other hand, when the option connector 14 is used, the loop surface 24a of the hook-and-loop fastener 24 and the hook surface 24b are engaged by pulling the terminal of the branch line 12b provided with the option connector 14 in a direction away from the trunk line 12a. The option connector 14 can be detached from the main line 12a after being released. Accordingly, by using the wire harness 12 according to the option connector fixing structure 10, the option connector 14 can be detachably connected to the trunk line 12 a of the wire harness 12.

  According to the option connector fixing structure 10 of the present embodiment as described above, the connection between the option connector 14 and the trunk line 12a is realized by using the loop surface 24a and the hook surface 24b of the surface fastener 24. 14 is not used, the hook line 24b of the hook-and-loop fastener 24 provided on the branch line 12b is attached to an arbitrary portion of the loop surface 24a of the hook-and-loop fastener 24 provided on the trunk line 12a. The option connector 14 provided at the terminal 12b can be fixed to the trunk line 12a of the wire harness 12. On the other hand, when the option connector 14 is used, the loop surface 24a and the hook surface 24b of the hook-and-loop fastener 24 can be easily pulled by pulling the terminal of the branch line 12b provided with the option connector 14 in a direction away from the trunk line 12a. The option connector 14 can be detached from the main line 12a after the engagement is released. Therefore, it can be easily fixed when not in use, and can be easily removed when it is used, as compared to the case where the tape is fixed as in the prior art. Will not occur. In addition, even if it is necessary to fix again, since it can be performed simply by attaching the hook surface 24b of the hook-and-loop fastener 24 to the loop surface 24a of the hook-and-loop fastener 24, a new work process and members are not required. The option connector 14 can be easily and simply fixed to the main line 12a.

  In addition, the trunk line 12a side of the hook-and-loop fastener 24 is covered with the loop surface 24a of the hook-and-loop fastener 24 because the trunk line 12a side, which is relatively heavy and easily generates a large noise due to vibration during vehicle travel, is covered with a vehicle body (not shown) Generation of collision noise with other members can be advantageously prevented.

  As mentioned above, although embodiment of this invention has been described, this invention is not limited at all by the specific description in this embodiment. For example, in the above-described embodiment, the outer peripheral surface of the branch line 12b is covered with the fixing member including the hook surface 24b of the hook-and-loop fastener 24 only in the vicinity of the end of the branch line 12b. 26, the outer peripheral surface of the branch line 12b may be covered with a covering material made of the hook surface 24b of the hook-and-loop fastener 24 over substantially the entire length in the longitudinal direction from the vicinity of the branch portion 22 to the end of the branch line 12b (see FIG. 2). Thereby, since the loop surface 24a and the hook surface 24b of the hook-and-loop fastener 24 can be adhered over a wide range, the option connector 14 when not in use can be firmly and stably held by the trunk line 12a. Furthermore, absorption of impact sound and interference sound at the time of contact of the branch line 12b using the hook surface 24b with the vehicle body or other members can be expected.

  In the above embodiment, the outer peripheral surface of the branch line 12 b is covered with the fixing member made of the hook surface 24 b of the hook-and-loop fastener 24, but the outer peripheral surface of the option connector 14 is a fixing member made of the hook surface 24 b of the hook-and-loop fastener 24. It may be covered, or both outer peripheral surfaces may be covered with a fixing member made of the hook surface 24 b of the hook-and-loop fastener 24.
