Abstract

PROBLEM TO BE SOLVED: To mount a harness without using another component such as a clip or the like by mounting the anchor-shaped lock reeds formed integrally with an insulating film and inserted and locked in the mount holes formed on a harness mount body, on one or plural parts of the insulating film which holds a plurality of coated electric wires. SOLUTION: An insulating film 12 is folded into two on a central line L to hold and bonded the coated electric wires arranged in flat. The point parts of the first and third locking reeds 13, 15 are overlapped to one another, and similarly those of the second and fourth locking reeds 14, 16, and those of the fifth and sixth locking reeds 17, 18 are overlapped to one another at tip ends of them. To mount this harness by utilizing, for example, the mount holes of a door inner wall surface of an automobile, the anchor parts of the overlapped locking reeds are erected to be inserted into the mount holes, whereby the anchor parts are locked to backside of the mount holes to be mounted. The clip components or the like becomes unnecessary, which brings the economical benefit, and the working of the locking reeds can be performed simultaneously with the cutting of the insulating film, so that the cost can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat harness formed (constituted) flat,
In particular, the present invention relates to a configuration of a flat harness in which the flat harness can be mounted on a mounting fixed body without using any mounting member such as a mounting clip.

[0002]

2. Description of the Related Art A flat harness having a flat shape is known, for example, in order to route it in a narrow space inside an automobile or to make it advantageous as a wire harness attached to a wall. ing. In order to arrange and fix these flat harnesses along the inner wall surface of the automobile door 1 as shown in FIG. 5, for example, a large number of covered electric wires 2 are arranged in a flat shape, and these covered electric wires 2 are arranged. Are attached and held at appropriate positions along the periphery of the flat harness 4 by holding (holding) the covered wire bundle in a flat shape by sandwiching and adhering the two resin films 3.
In the flat harness mounting surface of the door 1, a locking hole 6 corresponding to the mounting hole 5 is formed.
And a locking hole 6 provided in the door, and an anchor-shaped clip 7 is passed through the mounting hole 5 and the locking hole 6 from the front side of the flat harness 4. The flat harness 4 is attached to the door by locking the anchor portion of the flat harness 4 inside the locking hole 6. Reference numeral 8 denotes a connector connected to the insulated wire 2.

[0003]

As described above, in order to attach the conventional flat harness 4 to the attachment 1 such as a door, a plurality of clips 7 must be prepared and used. Must be manufactured in advance, which increases the cost for manufacturing the clip. Further, parts management by the above-mentioned clip and fastening work of the clip are required, which increases labor costs and causes a problem in terms of economy.

The present invention has been made in view of such a conventional problem, and enables a flat harness to be attached to a mounting body without using a separate component such as a clip. The purpose is to increase the economic efficiency of the abolition of the use.

[0005]

In order to achieve the above object, according to the present invention, at least one portion of an insulating film for holding a plurality of covered electric wires integrally with the insulating film. The flat harness is provided with an anchor-shaped locking tongue which is inserted and locked in a mounting hole formed in the harness mounting body.

According to a second aspect of the present invention, in addition to the first aspect, the anchor-shaped locking tongues form a pair which is overlapped in the opposite direction, and the pair of locking tongues are erected from each other. The flat harness is inserted and locked in the mounting hole.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on an embodiment shown in the drawings.

In FIG. 1, reference numeral 11 denotes a plurality of covered electric wires, and reference numeral 12 denotes an insulating film for keeping a plurality of the covered electric wires 11 arranged flat in a flat shape. Is, for example, a polyvinyl chloride resin film having a thickness of about 0.2 to 0.5 mm.

The form of the insulating film 12 is large enough to hold the covered electric wire 11 bundled flat. In other words, the bundled insulated wires 11 can be clamped by folding in two at the center line (L) of the insulating film 12. The bundle of covered electric wires 11 sandwiched by the insulating film 12 and the insulating film 12 are bonded to each other by an adhesive or welding means as appropriate.

On one edge (A) of the insulating film 12 which is parallel to the center line (L), from the middle of the edge (A), in a direction parallel to the edge (A). Moreover, first and second anchoring tongue pieces 13 and 14 each having an anchor shape extending in directions opposite to each other are stamped and formed. An edge (B) opposite to the edge (A) has an anchor shape extending from both end portions of the edge (B) in a direction parallel to the edge (B) and facing each other. Third and fourth locking tongues 15 and 16 are stamped and formed.

Further, the central portion of the insulating film 12 is separated from the edge (A) and the edge (B) by the center line (L) as a boundary, and is parallel to the center line (L). 5th and 6th anchor-shaped expendable in mutually opposite directions
Are formed by punching.

The insulating film 12 formed as described above is folded in two with the center line (L) as a boundary, and the covered electric wires 11 arranged in a flat shape are sandwiched and adhered. As a result, as shown in FIG. 2, the tip portions of the first locking tongue piece 13 and the third locking tongue piece 15 overlap each other, and similarly, the second locking tongue piece 14 and the fourth locking tongue piece 14 The tips of the tongue pieces 16 overlap each other, and the tips of the fifth locking tongue piece 17 and the sixth locking tongue piece 18 overlap each other.

The flat harness thus configured (formed) is mounted on the harness mounting body 19 by utilizing the inside of a mounting hole 20 formed in the harness mounting body 19, for example, the inner wall surface of the door of an automobile. Are anchor portions of the first and third locking tongue pieces 13 and 15 overlapping each other,
The anchors of the fourth locking tongues 14 and 16 and the anchors of the fifth and sixth locking tongues 17 and 18 are erected with each other, and the two anchors that are erected are connected to the harness. By pushing into the mounting hole 20 drilled in the body 19, the mounting hole 20
The anchor portion pushed into the inside is locked on the back side (inside) of the mounting hole 20, thereby fastening (attaching) the flat harness 21 to the harness mounting body 19.

As described above, according to the present embodiment, the insulating film itself constituting the flat harness 21 includes:
Since the flat harness is provided with a plurality of anchor-shaped tongues to be attached (fixed) to a harness attachment body to which the flat harness is to be attached, clip parts and the like, which are separate parts, are used to attach the flat harness to the attachment body. There is no need for ready use, which greatly improves economics.

Since the plurality of locking tongues provided on the insulating film can be formed at the time of cutting (punching) the insulating film, it is not necessary to form the locking tongues in a single step. The economics for the economy are also enhanced.

The locking tongues locked in each of the mounting holes 20 are locked by overlapping two locking tongues (anchor portions). The rigidity in the mounting hole 20 is increased, so that the flat harness 21
Can secure sufficient mounting strength.

[0017]

As described above, according to the present invention, when a flat harness is mounted on a harness mounting body, the flat harness is connected to the harness mounting body by using a plurality of locking tongues formed on the flat harness. Since there is no need to use a separate component such as a clip, which has been used in the related art, it is possible to improve the economy and the workability of attaching the flat harness.
