[Problems to be solved by the invention]
However, in order to attach the attaching member to the flexible film-like harness and attach it to the attached member in this way, in addition to the flexible film-like harness, components such as an attaching member are separately required, and the attaching work of the attaching component is also required. Therefore, there is a problem that the parts cost is increased and the number of man-hours is increased.
[0005]
The present invention has been made in view of such a problem, and an object of the present invention is to provide a mounting structure of a flexible film-like harness which can reduce the number of components and simplify the mounting operation.
[0006]
[Means for Solving the Problems]
The mounting structure of a flexible film-like harness according to the present invention is a mounting structure of a flexible film-like harness formed by laminating a conductor on an insulating film to a member to be mounted, wherein the member to be mounted includes a mounting protrusion. The flexible film-like harness has an insertion hole into which the mounting protrusion is inserted, and extends from an edge of the insertion hole toward the mounting protrusion, and is inserted in the insertion direction by inserting the mounting protrusion into the insertion hole. It is characterized by comprising an elastic movable piece that bends and resists in a direction opposite to the insertion direction.
[0007]
According to the present invention, the mounting protrusion provided on the member to be mounted is inserted into the insertion hole provided in the flexible film-like harness, and the elastic movable piece abuts on the mounting protrusion in a state of being bent in the insertion direction. The flexible film-like harness is fixed and attached in a state where the harness is pressed against the attached member by the resistance of the elastic movable piece. This makes it possible to reduce the number of components such as members to be attached to the member to be attached to the flexible film harness, thereby simplifying the attaching operation.
[0008]
The flexible film harness has a so-called flexible printed circuit (FPC) structure in which, for example, an insulating film and a conductor formed by etching are combined, and the flexible film harness is formed by combining an insulating film and a conductor formed by punching. It may have a so-called flexible flat cable (FFC) structure.
[0009]
Further, it is preferable that a plurality of elastic movable pieces are formed for one insertion hole.
[0010]
It is preferable that the mounting projection has a groove or a projection-shaped stopper at an end in a direction orthogonal to the insertion direction, which comes into contact with the distal end of the elastic movable piece in a bent state.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a diagram for explaining a flexible film harness mounting structure according to an embodiment of the present invention, and FIG. 2 is a partially enlarged perspective view of a mounting portion of the flexible film harness.
As shown in FIG. 1, a flexible film-like harness 1 has, for example, connectors 3a and 3b fitted to connectors such as electrical components at both ends of a band-shaped main body 2, and an attachment attached to a predetermined position with a tape 4. It comprises a mounting clip 5 as a member, tube protection members 6a and 6b for protecting the vicinity of the connectors 3a and 3b, and a corrugated tube 7 for protecting a predetermined position. The flexible film-like harness 1 is adjusted in shape by making use of its flexibility and bending predetermined bending portions 8a and 8b in accordance with the shape of a not-shown attached member such as an automobile frame. A predetermined position of the main body 2 between both ends of the flexible film-like harness 1 attached to the trim 9 as a member to be attached is, for example, an H-shaped thickness direction when viewed from the thickness direction of the flexible film-like harness 1. A plurality of insertion holes 10 formed by cuts penetrating the trim 9 are formed, and, for example, a plurality of columnar mounting projections 11 to be inserted into the insertion holes 10 are formed at positions corresponding to the insertion holes 10 of the trim 9. . In this example, the insertion hole 10 has a structure in which the elastic movable piece 15 is bent by the insertion of the mounting projection 11 to form a hole-shaped space (see FIG. 2).
[0012]
As shown in FIG. 2, the flexible film harness 1 is provided on a base film 12 made of an insulating resin film such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyimide (PI), and polyolefin (PO). A wiring 13 formed by patterning a conductive material such as copper foil is formed, and a coverlay 14 made of a synthetic resin or the like is placed on the base film 12 and the wiring 13. In this example, the flexible film-like harness 1 has a so-called flexible printed circuit (FPC) structure in which the wiring 13 is formed on the base film 12 by etching. A so-called flexible flat in which a wiring 13 formed by punching on the film 12 is attached, a base film 12 and a coverlay 14 are laminated on the wiring 13, a thin wire is crushed into a rectangular wire, and this is laminated on the base film 12. It may have a cable (Flexible Flat Cable: FFC) structure.
[0013]
In order to attach the flexible film-like harness 1 to the trim 9, the insertion hole 10 may be fitted into the attachment protrusion 11 of the trim 9. By doing so, the elastic movable piece 15 of the insertion hole 10 bends in the fitting direction of the mounting projection 11, and the tip thereof comes into contact with the mounting projection 11 and is caught, and is in the opposite direction to the insertion direction of the elastic movable piece 15. The main body 2 of the flexible film-shaped harness 1 is pressed against the trim 9 side and fixed by the resistance force to the trim 9. At the end of the mounting projection 11 in the direction perpendicular to the insertion direction, a groove or a projection-like stopper (not shown) is formed, which abuts the distal end of the elastic movable piece 15 in a bent state. In this case, the distal end portion of the elastic movable piece 15 is more reliably hooked on the mounting projection 11, so that the mounting state of the flexible film harness 1 to the trim 9 can be stabilized. Further, depending on the cutting mode of the insertion hole 10, only one elastic movable piece 15 may be formed for one insertion hole 10, or as shown in FIG. What is done may be.
[0014]
A portion of the flexible film-like harness 1 other than the portion attached to the trim 9 is attached to a frame (not shown) or the like by an attachment clip 5 having an anchor portion 5a.
[0015]
【The invention's effect】
As described above, according to the present invention, the mounting projection provided on the member to be mounted is inserted into the insertion hole provided on the flexible film-like harness, and the elastic movable piece is mounted in a state of being bent in the insertion direction. Since the flexible film-shaped harness is pressed against the member to be mounted by the resistance of the elastic movable piece, the flexible film-like harness is fixed and mounted to abut on the protrusion. Thereby, there is an effect that it is possible to reduce the number of components such as a member for attaching the flexible film harness to the member to be attached and to simplify the attaching operation.
