Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable suitable for wiring on an inner surface of a hatchback door glass or the like of an automobile, and more particularly, to a drive harness of a rear wiper attached to a lower end of the hatchback door glass from a body side. In a cable routed along the inner surface of the glass, an exterior material is attached to an electric wire converging group having a substantially circular cross section, thereby facilitating attachment to a member to be attached, such as the flat glass.

[0002]

2. Description of the Related Art As shown in FIG. 9, in a hatchback type automobile, a hatchback door glass (hereinafter abbreviated as "glass") 1 is attached to an upper frame of a body 8 via a hinge, and the glass 1 is opened and closed vertically. Stuff is provided. A rear wiper 3 and a wiper motor 5 are attached to the center of the lower end of this kind of openable / closable glass 1, and a cable 4 for driving the wiper motor 5 is connected to the body 8 from the center of the upper frame of the body 8. It is wired along the inner surface of the glass 1.

As shown in FIGS. 10 and 11, a cable 4 to be wired on the glass 1 accommodates a plurality of electric wires w, which are wired from a body 8 side, in a resin-molded protector 6. Is adhered to the inner surface of the glass 1 via the adhesive 7. At this time, the cable 4 needs to be routed from the upper edge of the glass 1 to the lower edge via one side edge, and since the distance is long, a single protector increases the size and the upper edge and the lower edge. The protector 6 is formed into straight portions 6A, 6B, 6C and curved portions 6D, 6E because the connecting portions to the edges and the side edges are curved so that integral molding is not easy. It is used in conjunction.

The above-described protector 6 has a straight portion 6
A to 6C are formed by extrusion molding using PVC, while the curved portions 6D and 6E are formed by injection molding using PP. Each part 6A-6E of these protectors 6
As shown in FIG. 11, a lid 6c is provided on the upper end of one side wall of the gutter-shaped main body 6a via a thin hinge 6b, and after the electric wire w is passed through the main body 6a, the lid 6c is closed. The lid 6c and the main body 6a are locked and locked.

[0005]

With the above-described cable wiring structure, since the protector 6 uses five separate parts, the number of parts is large, the cost is high, and the electric wires are attached to these protectors. In addition, there is a problem that the number of man-hours for mounting each protector on the glass increases.

Furthermore, since the straight portions 6A to 6C and the curved portions 6D and 6E are made of different resin, a difference occurs in the adhesive strength to glass, and there is a problem in the reliability of fixing the protector to glass. In particular, PP constituting the curved portions 6D and 6E has a problem of poor adhesiveness. Furthermore, the opaque black coating is applied to the inner surface of the glass to prevent these protectors from being viewed from the outside, but the structure where the protectors are connected in order from the inside can be seen, and the appearance is not good. There is also.

The present invention has been made in view of the above-described problems, and provides an exterior material composed of continuous parts without using the above-described protector, thereby reducing the number of parts and the number of mounting steps, and improving the appearance. The task is to make it happen.

[0008]

In order to solve the above-mentioned problems, according to the present invention, the electric wire is buried in a flexible outer material made of an insulating resin or rubber, and the electric wire is embedded in the outer material. The surface of the material to be attached to the material
A cable is provided in which both ends are protruded, and an adhesive reservoir is formed between the both protruding portions.

With the above construction, the cable is first applied to the adhesive reservoir, and the cable is lightly pressed against a flat or curved glass surface to complete the installation.
The presence of the projections at both ends makes it easy to apply the adhesive, and when mounted on glass, both projections expand outward and deform so that they can be securely bonded, and both projections become partitions and adhere. It also has the effect of preventing the protruding agent.

As described above, since the sheathing material can be continuously attached to the electric wire in the longitudinal direction and has flexibility, the intended shape can be set even at a bent and routed portion.

It is preferable that a plurality of electric wires are buried in the interior of the exterior member in a twisted state.

When the cable is bent as described above, when the cable is bent, each wire is bent while the inside and the outside of the bend are alternately replaced, and the deformation conditions accompanying the bending of all the wires are uniform. State. When multiple wires are simply buried, each wire has different expansion and contraction conditions due to bending, such as the outer wire being stretched and deformed more than the inner wire of the bend. High possibility of deformation. Therefore, in the stranded state, it can be bent relatively easily, and the bending arrangement can be performed easily. In addition, there is an advantage that the possibility of disconnection due to bending is reduced by the amount of unreasonable expansion and contraction.

It is preferable that the plurality of electric wires are embedded in the exterior material in a state of being housed in a flexible tubular interior material.

When a hollow tube is used as the interior material and is passed through the tube in tight contact with the tube, the positioning and holding of the electric wire can be ensured, and the electric wire can be more directly buried in the outer material. Since the tube is interposed, the sliding between the electric wire and the exterior material is improved, the coefficient of friction is reduced, and the tube is easily bent. Alternatively, as the interior material, a solid tube-shaped interior material in which electric wires are embedded with rubber or an elastomer may be provided as in the case of the exterior material, and the interior material may be further embedded in the exterior material. Also in this case, the positioning and holding of the electric wire can be reliably performed. As described above, when the electric wire is embedded in the interior material and embedded in the exterior material, there is an advantage that the electric wire can be more reliably protected and the electric wire can be protected even if the exterior material is torn temporarily.

The exterior material has a triangular or quadrangular cross section.
Alternatively, the protruding portion is formed by projecting both ends of one side of the semicircular shape, and an adhesive reservoir is provided therebetween (claim 4). The cable is formed by extruding an exterior material made of an insulating resin or rubber using the electric wire as a core material (claim 5).

Further, it is preferable that the plurality of electric wires are embedded in the exterior material in a state where the sliding powder is attached to the outer peripheral surface. With this configuration, when each part is expanded and contracted by bending the cable, the friction coefficient between the electric wires or between the electric wire and the exterior material is reduced by the sliding powder. Therefore, slippage between the electric wires or the outer material and the electric wire is improved, and the cable is easily bent, and the bending arrangement can be performed easily.

The electric wire buried in the exterior material may be formed only of a conductive material. For example, conductive materials may be arranged in parallel at a predetermined interval and buried with an exterior material. One side of the exterior material is used as a flat sticking surface, and both ends thereof are projected. It is sufficient to form an adhesive reservoir in advance.

The cable is fixed via the adhesive along the inner surface of the outer peripheral edge of the hatchback door of the vehicle with the adhesive reservoir filled with the adhesive.
