Description

  The present invention relates to a wire harness clamp for wiring a wire harness used for wiring of an electric device of a vehicle to the vehicle.

  A wire harness used for wiring of a vehicle (automobile) is routed to a predetermined position on a vehicle body panel via a wire harness clamp. Various applications have been filed for wire harness clamps (see, for example, Patent Document 1). Here, the wire harness means a bundle of a large number of electric wires, which are bundled into one by a converging tape, a waterproof tube or the like.

For example, an electric device may be assembled later on a vehicle that has been assembled once, such as a wheelchair lifting device in a welfare vehicle. In this case, it is necessary to add a wire harness for operating the electric device later. For example, it is conceivable that a new wire harness is stacked and fixed to a wire harness routed on a body panel by a binding band or the like. However, this method has poor workability and poor appearance. For this reason, as shown in FIG. 9, it can be considered that the wire harness clamps are stacked in multiple stages. When the wire harness clamps 51 are stacked, the wire 53a of the wire harness 53 attached to the lower wire harness clamp 52 may be bitten. In addition, since the upper wire harness clamp 51 is normally attached to the lower wire harness clamp 52 with the wire harness 54 attached, the wire harness 54 becomes a blind spot and it is difficult to visually recognize the lower state. Become. As a result, the wire 53a of the lower wire harness 53 may be disconnected, or the upper wire harness clamp may be half-fitted (fitted in the middle).

  In view of the above-described problems, an object of the present invention is to prevent a wire harness attached to a stacked wire harness clamp from being bitten when the wire harness clamp is attached in an overlapping manner.

Means for Solving the Problems and Effects of the Invention

The present invention for solving the above problems is as follows.
In order to route the wire harness to the vehicle, the mounting structure for attaching the second wire harness clamp to the first wire harness clamp attached to the vehicle,
Wherein the first wire harness clamp includes a clamp portion fixed to the vehicle, a front Stories body portion which is disposed on the side surface of the wire harness mounting portion where the clamp portion and integrally attached to supporting the wire harness, and a engaging portion for fitting the fitting hole portion provided in the second wire harness clamp attached to the differences from the clamp portion and the wire harness mounting portion before Symbol body portion,
The fitting hole is formed from the bottom surface of the second wire harness clamp toward the inside ,
The engagement portion has a length in a direction orthogonal to an attachment axis direction that is a direction in which the second wire harness clamp is attached to the first wire harness clamp from the distal end portion of the engagement portion to the main body portion. An inclined surface part that is continuously longer as it goes toward the side is provided ,
The wire harness mounting portion is disposed on a side wall of the main body portion extending from the end of the inclined surface portion to the clamp portion,
The element wires that are separated from the wire harness mounting portion and are positioned on the inclined surface portion are pushed out toward the wire harness mounting portion by the bottom surface portion of the second wire harness clamp .

  The present invention is configured as described above, and when the second wire harness clamp is mounted on the first wire harness clamp, the fitting hole portion of the second wire harness clamp is connected to the first wire harness. While being in contact with the inclined surface portion of the locking portion of the clamp for use, it is caused to approach relatively in the mounting axis direction. At this time, even when the wires of the wire harness attached to the first wire harness clamp are arranged on the inclined surface portion, when the first and second wire harness clamps are relatively approached, The second wire harness clamp pushes this strand. Thereby, the possibility that the second wire harness clamp may bite the wire is reduced. Since the worker can easily attach the second wire harness clamp to the first wire harness clamp, the attachment work is facilitated.

  It is desirable that the inner peripheral surface of the fitting hole portion of the second wire harness clamp is inclined at the same angle as the angle formed by the attachment axis and the inclined surface portion.

  Thereby, when the fitting hole part of the clamp for 2nd wire harnesses is fitted to the engaging part of the clamp for 1st wire harness, and both were made to approach relatively, the inner peripheral edge part of the said fitting hole part, No gap is formed between the engaging portion and the inclined surface portion, and the second wire harness clamp reliably pushes out the wire of the wire harness.

  And the latching means for preventing that both isolate | separate in the state which the engaging part of the clamp for said 1st wire harness was fitted in the fitting hole part of the said clamp for 2nd wire harness is provided. Can be like that.

  Thereby, the 1st and 2nd clamp for wire harnesses can be connected reliably. The locking means includes the locking hole provided in the engaging portion of the first wire harness clamp, and the engaging portion in a state where the engaging portion is fitted in the fitting hole portion of the second wire harness clamp. A locking claw that protrudes inward from the inner peripheral surface of the fitting hole portion so as to be elastically deformable so as to enter and be held in the stop hole can be provided.

  Examples of the present invention will be described. 1 is a perspective view of the clamp complex 100, FIG. 2 is a front view of the first and second wire harness clamps 101 and 102 separated, FIG. 3 is a side view of the state of FIG. 2, and FIG. It is a bottom view of the clamp 101 for 1st wire harnesses.

  Examples of the present invention will be described. In the present specification, as shown in FIG. 1, a clamp complex 100 formed by stacking first and second wire harness clamps 101 and 102 on a body panel 1 of a vehicle (not shown). explain.

  As shown in FIGS. 2 and 3, the body panel 1 of the vehicle is made of a metal plate having a predetermined thickness. The body panel 1 is gently curved in a side view, and a substantially rectangular mounting hole 2 is provided at the top. The first wire harness clamp 101 is attached to the attachment hole 2. Then, the second wire harness clamp 102 is stacked and attached to the first wire harness clamp 101. Both the first and second wire harness clamps 101 and 102 are made of a resin material. As shown in FIG. 1, the left-right direction of the clamp complex 100 is described as P, and the front-rear direction is described as Q.

  First, the first wire harness clamp 101 will be described. As shown in FIGS. 1 to 3, the first wire harness clamp 101 has a main body portion 4 provided on the upper portion of the flange portion 3 having a larger area than the mounting hole 2 of the body panel 1, and the lower portion thereof. And a clamp portion 5 that is inserted into the mounting hole 2 of the body panel 1. A wire harness attachment portion 6 made of an elongated thin plate is provided on the side surface portion of the main body portion 4 so as to protrude in the left-right direction P. A wire harness 201 is attached to each wire harness attachment portion 6 by a fixing means such as a tape or a binding band. In addition, in FIG. 2, the part of the clamp part 5 of the clamp 101 for 1st wire harnesses is displayed by the cross section.

  The cross-sectional shape of the clamp part 5 is a similar rectangular shape slightly smaller than the mounting hole 2 of the body panel. On each side surface portion in the left-right direction P of the clamp portion 5, elastic claws 9 are respectively provided in portions where the portion excluding the base end portion 8 is extracted by the slit 7. The elastic claw 9 is rotatable in the direction of the arrow 10 with the base end portion 8 as a fulcrum (see FIG. 2). Then, in a state where the first wire harness clamp 101 is not attached to the attachment hole 2 of the body panel 1, the top portion of each elastic claw 9 protrudes outward from the side surface portion of the clamp portion 5.

  When the clamp portion 5 of the first wire harness clamp 101 is inserted into the mounting hole 2 of the body panel 1, the pair of elastic claws 9 are pressed against the inner peripheral surface of the mounting hole 2. The pair of elastic claws 9 are elastically deformed so as to approach the insertion axis C <b> 1 of the mounting hole 2 in the direction of the arrow 10, with their base end portions 8 serving as pivot points. When the pair of elastic claws 9 pass through the mounting hole 2 of the body panel 1, the elastic deformation state of the pair of elastic claws 9 is released, and the pair of elastic claws 9 have their base end portions 8 as rotational fulcrums as arrows 10. It is elastically restored so as to be away from the insertion axis C1 in the direction. In this state, the tops of the pair of elastic claws 9 protrude outward from the mounting holes 2 of the body panel 1. Thereby, the clamp part 5 is hold | maintained in the attachment hole 2 of the body panel 1 in the retaining state.

  As shown in FIGS. 2 and 3, an engaging portion 11 is provided at the upper end portion of the main body portion 4. The engaging portion 11 is fitted into a fitting hole portion 12 (described later) of the second wire harness clamp 102. At this time, the axis in the fitting direction is set as the attachment axis C2. In the case of the present embodiment, the insertion axis C1 and the mounting axis C2 are provided on the same straight line. The engaging portion 11 includes a flat plate-like upright plate portion 13 erected in front of the central portion of the upper end surface of the main body portion 4 and upper end surfaces of both end portions of the upright plate portion 13 in the left-right direction P. And a pair of inclined surface portions 14 provided obliquely to the upper end surface of the main body portion 4. The length of each inclined surface portion 14 in the front-rear direction Q is continuous from the upper end portion (tip portion) of the upright plate portion 13 toward the lower end portion (the vicinity of the main body portion 4 of the first wire harness clamp 101). Is getting longer. The standing plate portion 13 is provided with a window portion 13 a for locking a locking claw 15 (described later) provided in the fitting hole portion 12 of the second wire harness clamp 102.

  Next, the second wire harness clamp 102 will be described. As shown in FIGS. 1 to 3, the second wire harness clamp 102 is provided with a fitting hole 12 into which the engaging portion 9 of the first wire harness clamp 101 is fitted. Further, the second wire harness clamp 102 has a wire harness mounting portion 16 made of an elongated thin plate protruding in the left-right direction P.

  The inner peripheral surface 17 on the rear side of the fitting hole 12 of the second wire harness clamp 102 has an inclination angle θ (each inclined surface portion) of the pair of inclined surface portions 14 of the engaging portion 11 in the first wire harness clamp 101. 14 and the mounting axis C2). That is, the angle formed between the rear inner peripheral surface 17 and the mounting axis C2 is θ. In addition, the inner peripheral surface 18 on the front side in the fitting hole 12 is provided in parallel with the attachment axis C <b> 2 so as to be disposed close to the upright plate 13 in the fitted state with the engaging portion 11. And the latching claw 15 which goes to the attachment axis line C2 protrudes in the part extracted except the base end part 20 by the slit 19 from the inner peripheral surface 18 of the front side. The locking claw 15 is rotatable in the direction of the arrow 21 with the base end portion 20 as a rotation fulcrum (see FIG. 3). The latching claw 15 is provided in a state in which the engaging portion 11 of the first wire harness clamp 101 is fitted in the fitting hole portion 12 of the second wire harness clamp 102. Enters the window 13a. Thereby, the clamp 102 for 2nd wire harnesses is hold | maintained in the clamped state by the clamp 101 for 1st wire harnesses (refer FIG. 6).

  The operation of the clamp complex 100 of the present embodiment will be described. The clamp portion 5 of the first wire harness clamp 101 is inserted through the mounting hole 2 of the body panel 1. The pair of elastic claws 9 are pressed by the mounting holes 2 of the body panel 1 and are elastically deformed with the base end portion 8 as a rotation fulcrum. When the pair of elastic claws 9 pass through the mounting hole 2 of the body panel 1, the elastic claw 9 is elastically restored in the opposite direction with the base end portion 8 as the pivot point. Thereby, the clamp 101 for 1st wire harnesses is hold | maintained in the attachment hole 2 of the body panel 1 in the retaining state. The wire harness 201 is fixed to the wire harness attachment portion 6 of the first wire harness clamp 101 by fixing means (tape, binding band, etc.).

  The fitting hole 12 of the second wire harness clamp 102 is fitted into the engagement portion 11 of the first wire harness clamp 101 in this state. That is, as shown in FIG. 3, the engaging portion 11 of the first wire harness clamp 101 and the fitting hole portion 12 of the second wire harness clamp 102 are arranged to face each other, and they are arranged in the direction of the attachment axis C2. Move relatively close. At this time, as shown in FIG. 5, the opening-side end edge portion 17 a is replaced with the first wire harness clamp 101 on the inner peripheral surface 17 on the rear side of the fitting hole portion 12 of the second wire harness clamp 102. Both are relatively brought close to each other while being in contact with the inclined surface portion 14 of the engaging portion 11. As a result, no gap is formed between the inner peripheral surface 17 on the rear side of the fitting hole portion 12 and the inclined surface portion 14 of the engaging portion 11. For this reason, even if it is a case where the strand 22 removed from the wire harness 201 of the clamp 101 for 1st wire harness has adhered to the inclined surface part 14 of the engaging part 11, the inner peripheral surface of the fitting hole part 12 18 slides down the inclined surface portion 14 of the engaging portion 11 diagonally, thereby pushing out the strand 22 attached to the inclined surface portion 14. This prevents the second wire harness clamp 102 from biting the wire 22 of the wire harness 201. Moreover, the side by which the wire harness 201 is attached in the engaging part 11 becomes an inclined surface (inclined surface part 14), The effect that the strand 22 of the wire harness 201 becomes difficult to adhere is also show | played.

  As the second wire harness clamp 102 approaches the first wire harness clamp 101 relatively, the locking claw 15 provided on the inner peripheral surface 18 on the front side of the fitting hole portion 12 11 abuts on the upright plate portion 13. The locking claw 15 is elastically deformed in the direction away from the attachment axis C <b> 2 in the direction of the arrow 21 with the base end portion 20 as a rotation fulcrum. Then, when the locking claw 15 enters the window portion 13a of the upright plate portion 13, the locking claw 15 is elastically restored and the locking claw 15 is locked to the window portion 13a. Thereby, the clamp 102 for 2nd wire harnesses is hold | maintained in the retaining state with respect to the clamp 101 for 1st wire harnesses.

  As described above, in the first and second wire harness clamps 101 and 102 of the present embodiment, the end edge portion 17 a of the rear inner peripheral edge portion 17 in the fitting hole portion 12 of the second wire harness clamp 102. Are brought into contact with the inclined surface portion 14 of the engaging portion 11 of the first wire harness clamp 101, and the two are simply connected in the direction of the attachment axis C2. At this time, the possibility that the second wire harness clamp 102 bites the element wire 22 of the wire harness 201 of the first wire harness clamp 101 is very small. For this reason, even if the wire harness 201 is attached to the second wire harness clamp 102, the operator does not check the state of the first wire harness clamp 101, and the second wire harness is created without any effort. The clamps 102 can be stacked, and the mounting work is extremely easy.

  In the second wire harness clamp 102 of the above-described embodiment, the inner peripheral surface 17 on the rear side of the fitting hole portion 12 is an inclined surface. However, like the second wire harness clamp 103 of the embodiment shown in FIG. 7, the inner peripheral surface 23 on the rear side of the fitting hole 12 may be a straight shape. In this case, as shown in FIG. 8, when the locking claw 15 of the second wire harness clamp 103 is locked to the window portion 13 a of the upright plate portion 13 of the first wire harness clamp 101, the front-rear direction Q It is desirable to form a straight-shaped portion 24 at the lower end portion of the inclined surface portion 14 so that the inner peripheral surface 23 on the rear side of the fitting hole portion 12 is fitted.

  In the first and second embodiments described above, the wire harness clamps are stacked in two stages. However, the wire harness clamps may be stacked in three or more stages. The second wire harness clamp 102 does not necessarily have to be stacked on top of the first wire harness clamp 101. For example, the case where the 2nd wire harness clamp 102 is piled up and attached from the lower part to the clamp 101 for the 1st wire harness attached to the ceiling surface of the vehicle may be sufficient. In this case, since the strand 22 hangs down, it becomes very easy to bite the strand 22 with the conventional wire harness clamp. However, in the wire harness clamp mounting structure of the present embodiment, the second wire harness clamps 102 and 103 are mounted while pushing out the wire 22, so that the wire 22 can be bitten even when stacked from below. It is extremely small.

  In each of the above-described embodiments, the insertion axis C1 of the first wire harness clamp 101 and the attachment axis C2 of the second wire harness clamp 102 are provided on the same straight line. However, this is the case where the insertion axis C1 and the mounting axis C2 intersect (that is, in the first wire harness clamp 101, the clamp portion 5 and the engagement portion 11 are not provided on the same straight line). May be.
