Description

  The present invention relates to a main harness and a harness clip for holding a branch harness branched from the main harness.

  In the interior of an automobile, electric wires of various electrical components such as a room lamp are bundled by being taped with vinyl tape or the like and arranged as a harness. Such a harness generally has a main harness bundled linearly and a branch harness branched from the main harness corresponding to the location of each electrical component. The branch harness is formed by bending the backbone harness at a predetermined location. At that time, the root portion of the portion where the branch harness is bent often floats more than the backbone harness. This is because the harness is often bent with a relatively large margin to prevent the effect of elastic energy generated when the harness is bent, the effect of the elastic restoring force of the harness itself, or disconnection. It is presumed that a part is produced and that part is played.

  For this reason, more tape is wound and tightened on the bent root portion of the branch harness than the main harness to suppress the lifting. However, the above-described tape winding requires a large number of work steps and increases the cost. Therefore, there has been proposed a support that can hold a harness having a branch harness without winding the tape as much as possible.

  Patent Document 1 below discloses a protector having a pair of upper and lower protector bodies each having a substantially T shape that accommodates a harness, and a clamp that is locked to the protector body. The clamp is locked to the protector, and the harness is fixed in the upper and lower protectors.

  Patent Document 2 listed below includes a protector having a hook shape, a notch formed on a side wall of the protector, and a regulating member that restricts bending of the harness at the notch. The harness is held in the protector and is bent in a state where the overlapping of the branch harnesses is reduced by the restriction member to suppress the branch harness from being lifted.

The following Patent Document 3 discloses a clip including a holder for holding a basic harness and a band extending from one end of the holder, and holds the basic harness with the holder and holds the branch harness with the band. is doing.

  However, in the case of the above-mentioned patent document 1, since upper and lower protectors and clamps are necessary, the number of parts is large, resulting in inconvenience in cost and assembly workability. Moreover, since the protector is formed large enough with a margin to accommodate harnesses of various sizes, large and small, the possibility that the root part of the branch harness will float cannot be thrown away. If the root part rises in the protector, it may cause abnormal noise or the harness itself may be disconnected.

  In the case of the above-mentioned Patent Document 2, there is a problem in terms of work efficiency because the harness is inserted into the protector and then bent inside the protector via the regulating member and pulled out from the notch. Furthermore, since there is no restriction member above the root portion of the branch harness, the lifting of the root portion cannot be completely suppressed. When the protector is covered, the same as in Patent Document 1 above. In addition, there are problems in cost and assembly workability.

  Furthermore, in the case of the above-mentioned Patent Document 3, it is necessary to tighten the branch harness with a band after holding the basic harness, which causes a problem in workability.

  Therefore, an object of the present invention is to provide a harness clip that can hold the main harness and the branch harness branched from the main harness with good workability and can reliably suppress the floating of the branch harness. There is.

  In order to achieve the above object, a first aspect of the present invention is a harness clip for holding a main harness and a branch harness branched from the main harness, and has a tubular shape as a whole, and extends in the axial direction.

The branch harness can be held at a predetermined position by suppressing the lifting. As described above, since the basic harness and the branch harness can be easily held by simply inserting the branch harness into the notch after the main harness is inserted into the harness holder, the workability of the holding work can be improved. .
A second aspect of the present invention provides the harness clip according to the first aspect, wherein the pressing piece is inclined along the circumferential direction of the notch portion in the insertion direction of the branch harness. is there.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, a harness clip is provided in which ribs project from the periphery of the notch.

  According to the above invention, since the rib protrudes from the periphery of the notch portion, the notch portion can be reinforced and the contact area with the branch harness is increased, so that the branch harness can be held more stably. can do.

  According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the harness holder is formed with a leg portion that engages with the attached member, and the leg portion is attached to the attached member. A harness clip in which a wall portion adjacent to the attached member is formed when engaged is provided.

  According to the above invention, since the wall portion adjacent to the attached member is formed, even if a large load is applied to the harness clip, the load is received by the wall portion so that the harness clip is attached to the attached member. It can be held in a stable posture. Moreover, even when a load in the rolling direction is applied to the harness clip, a strong resistance can be obtained, so that the harness clip can be stably held.

  According to the harness clip of the present invention, the main harness is inserted into the harness holder, and the branch harness is inserted into the cutout portion in that state, so that the presser piece is bent and the branch harness is inserted below the presser foot. Therefore, the basic harness and the branch harness can be easily held to improve the workability thereof, and the branch harness can be held at a predetermined position by suppressing the lifting of the branch harness.

  Hereinafter, with reference to FIGS. 1-3, one Embodiment of the harness clip of this invention is described.

  As shown in FIG. 1, this harness clip 10 (hereinafter referred to as clip 10) is used to dispose a harness H on a member to be attached such as a vehicle body panel 1 of an automobile.

  For example, the harness H is configured by bundling electric wires connected to an automobile room lamp, a power seat, and other electrical components. The harness clip 10 of the present invention includes a main harness H1 bundled in a straight line, and a branch harness H2 branched from the main harness H1 and bent substantially at right angles to the main harness H1. It can be effectively applied to the harness H having a substantially T-shape as a whole.

  The clip 10 is mainly composed of a harness holder 30 for holding the harness H (hereinafter referred to as the holder 30) and a leg portion 50 for attaching to the vehicle body panel 1.

  Referring also to FIG. 3, the holder 30 has a cylindrical shape as a whole, and an opening 31 is formed with a predetermined width along the axial direction thereof, and has a substantially C-shaped cross section. The harness holder 30 accommodates and holds the basic harness H1. Further, the width D1 along the radial direction of the opening 31 is formed slightly smaller than the outer diameter D2 of the backbone harness H1, so that the backbone harness H1 can be retained and retained. Further, a pair of flange pieces 32 and 32 are formed in a tapered shape from the peripheral edge along the axial direction of the opening 31 so that the basic harness H1 can be inserted into the harness holder 30 smoothly and stably. ing.

  A notch 35 is formed along the circumferential direction at substantially the center in the axial direction of the holder 30. The notch 35 is formed by being cut out from the opening 31 by a predetermined length along the circumferential direction, and thus communicates with the opening 31 (see FIG. 1). Then, after the main harness H1 is inserted into the holder 30, the branch harness H2 branched from the main harness H1 can be inserted into the notch 35.

  Further, a rib 36 projects from the notch 35 along the periphery of the notch 35 toward the outer periphery. The rib 36 includes a bottom wall rib 37 projecting along the lower surface of the notch 35 and a pair of side wall ribs 38 projecting along both side surfaces of the notch 36. Thus, by providing the rib 36 on the periphery of the notch portion 35, the notch portion 35 can be reinforced, so that the possibility of breakage or the like can be reduced. Further, even if the branch harness H2 is inserted into the notch 35 and then the position of the branch harness H2 is pulled or the like, the rib 36 contacts the branch harness H2 with a large contact area. H2 can be held more stably.

  Further, as shown in FIGS. 3A and 3C, a pair of wall portions 39, 39 protrudes along the side wall ribs 38, 38 of the notch portion 35 below. The wall portion 39 has a lower side parallel to the mounting surface when viewed from the side, and a part of the wall portion 39 is connected to a support portion 33 described later. Further, the lower end surface of the wall portion 39 is flush with the lower end surface of the support portion 33. As shown in FIG. 3B, the wall portions 39, 39 are adjacent (adjacent or abutted) to the upper surface of the vehicle body panel 1 when the clip 10 is engaged with the vehicle body panel 1 by the legs 50. ).

  As shown in FIGS. 1 and 3C, a presser piece 40 protrudes from the inner surface of the notch 35. The presser piece 40 in this embodiment has a shape that protrudes from one inner surface of the notch 35 and extends obliquely downward toward the other inner surface of the notch 35, and the notch 35. When viewed from above (a direction perpendicular to the axial direction), the holder 30 has a shape extending from the inside to the outside. Further, the upper surface 40a and the lower surface 40b of the pressing piece 40 are gently inclined along the circumferential direction of the notch portion 35, and do not protrude from the thickness T of the notch portion 35 when viewed from the axial direction. (See FIG. 3A).

  Such a presser piece 40 bends downward when the branch harness H2 is inserted from above, so that the branch harness H2 can be inserted into the notch 35 and abuts against the upper end of the branch harness H2. The branch harness H2 is pressed from above and serves to suppress the lifting. The presser piece 40 is connected to one side of the notch 35 and has a shape extending toward the other side of the notch 35, and the branch harness H2 can be inserted into the notch 35. It is only necessary that the upper end portion can be pressed, and the shape is not particularly limited.

  In the case of the presser piece 40 of the embodiment shown in FIGS. 1 to 3, the upper surface 40 a and the lower surface 40 b are gently inclined along the circumferential direction of the notch portion 35 and viewed from the axial direction. Since it is formed so as not to protrude from the thickness T of the notch 35, when the branch harness H2 is inserted into the notch 35, the presser piece 40 is gradually not pressed by the branch harness H2 and gradually. Will be pressed. Along with this, the presser piece 40 can be gradually bent, so that the presser piece 40 can be prevented from being damaged or broken. Furthermore, since the pressing piece 40 is formed so as not to protrude from the thickness T of the notch 35, it is possible to improve moldability when injection molding is performed using a synthetic resin or the like.

  As shown in FIGS. 3 (A) and 3 (C), a support portion having a predetermined width along the axial direction is provided at a lower position shifted from the opening 31 of the holder 30 by approximately 90 degrees when viewed from the side. 33 is formed. That is, the support portion 33 has a shape projecting downward from the peripheral wall of the arcuate holder 30, and the lower end surface thereof is flat and connected to the wall portion 39 described above. A leg portion 50 projects from the lower end surface of the support portion 33. By forming the leg portion 50 via the support portion 33 in this manner, the holder 30 can be attached to the vehicle body panel 1 more stably than when the leg portion 50 is directly formed on the peripheral wall of the holder 30. it can.

  As shown in FIG. 3C, the leg portion 50 includes a support column 51 extending from the lower end surface of the support portion 33 and a pair of elastic legs extending slightly obliquely from the tip end of the support column 51 toward the support portion 33. 52 and 52, and step portions 53 and 53 are formed at the tip ends of the elastic legs 52 and 52. Further, a flange portion 54 is formed on the periphery of the base end portion of the support column 51 so as to spread in a skirt shape obliquely downward toward the tip end of the support column 51. The step portion engages with the rear peripheral edge of the engagement hole 2 of the vehicle body panel 1, and the clip 10 is fixed to the vehicle body panel 1 via the leg portion 50. Further, the flange portion 54 elastically contacts the periphery of the engagement hole 2 when the clip 10 is engaged with the vehicle body panel 1, thereby suppressing rattling or the like of the clip 10. In addition, the leg part 50 is not limited to the said shape, What is necessary is just a shape which can be engaged with the vehicle body panel 1. FIG.

  Next, an example of a process of holding the harness H on the vehicle body panel 1 using the clip 10 of the present invention will be described.

  First, the basic harness H <b> 1 is inserted into the holder 30 through the opening 31. In that state, the branch harness H2 is rotated in the axial direction as shown by the arrow in FIG. 3A and inserted into the notch 35 of the holder 30. Then, the presser piece 40 formed in the notch 35 is pressed against the outer peripheral surface of the branch harness H2, the presser piece 40 is bent downward, and is pushed in until the branch harness H2 is positioned below the presser piece 40. Then, the presser piece 40 is elastically restored and its tip abuts against the upper end of the branch harness H2, and the branch harness H2 is pressed from above, so that the lifting of the branch harness H2 is completely suppressed and branched. The harness H2 can be held (see FIG. 2).

  Thus, according to the clip 10 of the present invention, the backbone harness H1 and the branch harness H2 can be easily held by simply inserting the branch harness H2 into the cutout portion 35 after inserting the backbone harness H1 into the holder 30. The workability of the harness H holding work can be improved, and the tape winding around the branch harness which has been conventionally required is not required, so that the cost can be reduced.

  Then, the holder 30 is attached to the vehicle body panel 1. That is, when the leg portion 50 of the clip 10 is inserted from the front side of the engagement hole 2 of the vehicle body panel 1, the elastic legs 52, 52 are pressed to the periphery of the engagement hole 2 and bent inward, and the step portion 53 is When reaching the engagement hole 2, the elastic legs 52, 52 are elastically restored and engaged with the peripheral edge on the back side of the engagement hole 2 so that the clip 10 is attached to the vehicle body panel 1 as shown in FIG. 2. Become.

  As described above, when the leg portion 50 is engaged with the vehicle body panel 1, the wall portions 39 and 39 formed on the clip 10 are adjacent to the upper surface of the vehicle body panel 1 as shown in FIG. Therefore, even when a large load is applied to the clip 10, the wall portions 39, 39 can contact the upper surface of the vehicle body panel 1 and receive the load. Therefore, the clip 10 can be held in a stable posture with respect to the vehicle body panel 1.

  Further, when the harness H is pulled in the state shown in FIG. 2, a lateral force acts on the clip 10, and a force (a rolling direction force) in a direction in which the leg portion 50 is pulled out from the engagement hole 2 of the vehicle body panel 1. However, as described above, since the wall portions 39 and 39 are in contact with the upper surface of the vehicle body panel 1, a strong resistance against the force in the rolling direction can be obtained, and the clip 10 and the engagement hole 2 of the vehicle body panel 1 can be stably held.

  In the above holding step, the harness H1 is inserted into the clip 10 and the branch harness H2 is rotated and inserted into the cutout portion 35. However, the harness 10 is not moved and the clip 10 is put on the backbone harness H1. The clip 10 itself may be rotated so that the branch harness H2 is inserted into the notch 35. Alternatively, the clip 10 may be attached to the vehicle body panel 1 first, and the harness H may be held by the clip 10 later.

  4A, 4B and 4C show another embodiment of the harness clip of the present invention. Note that substantially the same parts as those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The harness clip 10a (hereinafter referred to as the clip 10a) of this embodiment is different from the above-described embodiment in that the leg portion 50 for engaging with the vehicle body panel 1 is not provided. In other words, the clip 10a is not premised on being attached to a member to be attached such as the vehicle body panel 1, and is intended to be held without breaking the bundle of wires constituting the harness H and arranged at a predetermined position. .

  The clip 10a has ribs 36a projecting along the periphery of the notch 35, as in the above embodiment. However, it differs from the above embodiment in that the side wall ribs 38a projecting from both sides are formed over the entire circumference excluding the notch 35 of the holder 30.

  In the clip 10a of this embodiment, the overall shape can be reduced to the extent that the leg portion 50 is not formed. Therefore, for example, when the engagement hole 2 for engaging the leg portion 50 with the attached member cannot be formed, or the gap between the attached member and a cover member such as a carpet is small, and the leg portion 50 is simply inserted. Even when the clearance cannot be ensured, or when the attachment space for the attached member cannot simply be secured, the harness H1 having the branch harness H2 can be effectively held.

  INDUSTRIAL APPLICABILITY The present invention can be used as a harness clip that can hold a basic harness and a branch harness branched from the basic harness with good workability, and in particular can reliably suppress the floating of the branch harness.
