Description

  The present invention relates to a wire harness fixing tool, and more particularly, to fix a wire harness to a fixing material such as a vehicle body panel for a wiring harness routed in an automobile, and in particular, a position with an attachment position provided on the fixing material. The adjustment can be performed in a wide range.

  Conventionally, clips are attached to the wire harness within the allowable crossing range with respect to the mounting holes provided in the body panel, etc., but when the wire harness is routed, a positional shift occurs, and the wire harness is attached to the body panel. Therefore, there are various types in which the clip position can be adjusted.

  For example, Japanese Patent Laid-Open No. 9-210252 (Patent Document 1) related to the previous application of the present applicant provides a clip 1 shown in FIG. The clip 1 has a substrate member 2 fixed to the wire harness W and a single rod bent to connect the first shaft portions 3a and 3a at both ends to the substrate member 2 in a freely rotatable manner. A shaft member in which an intermediate portion sandwiched between the first shaft portions 3a and 3a is parallel to the longitudinal direction of the wire harness W and a second shaft portion 3b is provided at a predetermined distance from the first shaft portions 3a and 3a. 3 and a clip member 4 slidably and rotatably attached to the second shaft portion 3 b of the shaft member 3.

  Since the clip member 4 is slidable in the longitudinal direction with respect to the wire harness W and can also be rotated around an axis parallel to the wire harness W, the clamp 1 can change the position and orientation of the clip member 4. It can be changed in various directions, and the absorption direction of the tolerance with the locking hole of the vehicle body can be increased. However, there is room for improvement in that the movable range in the longitudinal direction of the clip member 4 with respect to the wire harness W is small, and the fixing point of the clip member 4 is not fixed, and the wire harness W fixed to the vehicle body is likely to be rattled. There is.

  On the other hand, Japanese Patent Laid-Open No. 11-164454 (Patent Document 2) proposes a clamp 5 shown in FIGS. The clamp 5 has an inverted L-shaped frame projecting from both sides in the width direction of the substrate member 6 fixed to the wire harness, and forms a guide frame 6a having one end as a closed wall and the other end as an opening. ing. After the clip member 7 and the spring 8 for biasing the clip member 7 are inserted and assembled in the guide frame portion 6a, the stopper 6b protruding from the board member 6 is tilted to open the open end of the guide frame portion 6a. Is configured to be closed.

  The clamp 5 can take a large movable range in the longitudinal direction of the clip member 7 with respect to the wire harness, but there is a problem in that the movable direction is limited to one direction. Moreover, since the long guide frame part 6a which fits the clip member 7 so that sliding is possible is integrally provided in the board | substrate member 6, a guide frame part is so large that the movable range of the clip member 7 is enlarged. There is also a problem in that the board member 6 integrated with 6a needs to be elongated, and the tape winding fixing positions to the wire harnesses at both ends of the board member 6 are separated from each other, so that the layout is easily restricted.

Japanese Patent Laid-Open No. 9-210252 JP-A-11-164454

  The present invention has been made in view of the above problems, and when misalignment occurs between a locking hole of a fixing member such as a vehicle body panel and a clip attached to a wire harness, not only one direction but also multiple directions and a wide range. It is an object of the present invention to provide a wire harness fixture that can absorb misalignment.

In order to solve the above problems, the present invention is a fixture for attaching a wire harness to be wired to a vehicle to a vehicle body
A fixing member that is fixed to the wire harness, and a vehicle body locking member that is detachably attached to the fixing member.
The fixing member is either a substrate portion that is tape-fixed to the wire harness, or a wire harness attachment portion that is either a band winding portion including a band wound around the wire harness and a band locking portion; and the wire harness attachment portion And even-numbered divided pieces each independently protruding in the shape of an even regular polygonal frame, and each divided piece has its protruding end bent outwardly to project a locking piece, and the locking piece While protruding from the tip of the
The vehicle body locking member includes a long base portion and a clip portion protruding from the base portion,
The base is formed at both ends of a central plate portion projecting from the clip portion, both side plate portions projecting from the opposite side of the clip portion by bending the both ends, and the inside end by bending the tip of the both side plate portions. A projecting locked plate portion, and forming a guide groove portion having a U-shaped cross section for fitting the locking piece of the divided piece,
A plurality of pairs of mounting holes for inserting the protrusions are provided at opposite positions of the side plate portions at intervals in the length direction, or one continuous mounting hole is provided, and a plurality of pairs are formed from the inner surfaces facing the mounting holes. There is provided a fixing tool for a wire harness, wherein the locking projections are provided at intervals in the length direction.

  It is preferable that the number of the divided pieces is four, six, or eight so that the fixing member has a square, regular hexagonal, or regular octagonal frame shape.

  The wire harness fixture having the above-described configuration is configured to fit the locking piece of the fixing member into the guide groove portion of the vehicle body locking member when the vehicle body locking member is attached to the fixing member formed separately. Thus, it is possible to regulate the positional deviation in the vertical separation direction between the vehicle body locking member and the fixing member. In addition, by inserting the protrusion of the fixing member into the mounting hole of the vehicle body locking member, the displacement of the vehicle body locking member and the fixing member in the sliding direction is restricted, and the fixing member and the vehicle body locking member are Can be locked.

  The wire harness fixture has a base portion of the vehicle body locking member that is long, and a plurality of pairs of attachment holes for inserting the protrusions of the fixing member in the long base portion at intervals in the length direction. By providing, it is possible to increase the slide movement distance of the vehicle body locking member, and thus the clip portion.

  Moreover, the sliding movement direction with respect to the fixing member of the vehicle body locking member can be changed depending on which of the divided pieces projecting in the shape of a regular polygon frame is fitted with the vehicle body locking member. Specifically, in the case where the four divided pieces project in a square frame shape on the fixing member, by selecting the mounting direction of the vehicle body locking member from two directions orthogonal to each other, The tolerance with the locking hole can be absorbed in two directions, and when the six divided pieces project in the shape of a regular hexagonal frame, the sliding movement direction of the vehicle body locking member is set to 60 degrees. By selecting from the three directions, the tolerance with the locking hole of the vehicle body can be absorbed in the three directions, and when eight divided pieces project in a regular octagonal frame shape, By selecting the sliding movement direction of the stop member from four directions having an intersection angle of 45 degrees, the tolerance with the locking hole of the vehicle body can be absorbed in the four directions.

  As described above, when the wire harness fixture of the present invention is used, the attachment position of the vehicle body locking member relative to the fixation member, that is, the attachment position of the clip portion relative to the wire harness can be adjusted by moving in multiple directions. Since the movable distance in the direction can be increased, the movable range of the clip portion can be expanded, and the tolerance absorption range with respect to the locking hole of the vehicle body can be expanded.

  In the present invention, in order to increase the movable distance of the clip portion relative to the wire harness, the base portion of the vehicle body locking member is elongated, and a guide groove portion for guiding the movement is provided in the elongated base portion. It is not necessary to set the fixing member to be fixed to the wire harness to be long. Therefore, since the wire harness attachment part of the fixing member fixed to the wire harness can be constituted by a short substrate part or a band winding part, the degree of freedom in layout can be increased.

  Furthermore, since the mounting position of the clip portion relative to the wire harness can be determined by inserting the protrusion of the fixing member into the mounting hole of the vehicle body locking member, the fixing point of the wire harness is determined and fixed to the vehicle body. The looseness of the wire harness can be prevented.

  Furthermore, when the vehicle body locking member is slid, removed from the fixing member, or removed and replaced with a different pair of divided pieces, a pair of opposed divided pieces in which projections are inserted into the mounting holes, By pressing with a finger from the outside, the pair of split pieces bend in the direction of proximity to each other, and at the same time, the protrusions are detached from the mounting holes to release the lock coupling state of the vehicle body locking member and the fixing member. Can do. Further, since the divided pieces are not connected to the adjacent divided pieces in the shape of a regular polygonal frame and project independently from each other, it is possible to sufficiently ensure the bending deformation of each divided piece. The removal operation and the slide operation of the locking member can be easily performed.

The clip portion protrudes from one end side in the length direction of the central plate portion of the base portion.
Thereby, the position of a clip part can be moved also by once removing a vehicle body locking member from a fixing member, and changing so that the position of the said clip part may be front-back or left-right reverse. Furthermore, since the movable distance in each direction with respect to the wire harness of the clip portion can be further increased by using together with the slide movement, the absorption range of the tolerance with the locking hole of the vehicle body can be greatly expanded. .

  Each of the divided pieces may be provided with a rib extending on the inner surface thereof in the protruding direction of the divided piece. By providing the ribs, the strength of the divided pieces can be increased, and damage to the divided pieces and deterioration of the lock function can be prevented.

  As described above, according to the present invention, the vehicle body locking member protruding from the clip portion can be moved in multiple directions with respect to the wire harness, and the movable distance in each direction can be increased. The movable range of the clip portion is widened, and the tolerance absorption range with respect to the mounting hole of the vehicle body can be expanded.

  By inserting the protrusion of the fixing member into a desired mounting hole of the vehicle body locking member, the mounting position of the clip portion with respect to the wire harness can be determined, so the fixing point of the wire harness is also determined, and the wire fixed to the vehicle body The rattling of the harness can be prevented.

  In addition, when the guide groove portion for guiding the sliding movement of the vehicle body locking member is provided on the side of the elongated vehicle body locking member, the fixing member fixed to the wire harness has a protrusion to be inserted into the mounting hole. It is not necessary to set the fixing member to be long, and the degree of freedom in layout such as a tape winding fixing position on the wire harness can be increased.
