Description

The present invention relates to a method for assembling a composite cable and a composite cable, for example, a method for assembling a composite cable for a vehicle and a composite cable.

Wiring systems for vehicles such as automobiles use wire harnesses in which cables such as communication cables, power cables, and ground cables manufactured independently of each other are bundled with tape or the like as needed. Generally, in a vehicle wire harness, an operator manually binds a communication cable or a power cable by using a binding member such as a vinyl tape or an exterior material.

In Patent Document 1, a conductor cable such as a power cable or an earth cable and a tube are extruded together and covered with a coating, and the communication cable is inserted into the tube afterwards to integrate the conductor cable and the communication cable. The structure to be planned is disclosed.

In addition, the conventional composite cable requires a member cost of a binding member used when binding each cable with a tape. Further, in the conventional composite cable, the conductor cable and the communication cable are bound by the manual work of the operator, so that the appearance and the quality are varied.

In the technique disclosed in Patent Document 1, it is generally difficult to pass a cable in which terminals and connectors are connected to both ends in a tube.

<< Embodiment 1 >>
FIG. 1 is a perspective view of the composite cable 1A according to the first embodiment. Further, FIG. 2 is a cross-sectional view of the composite cable 1A according to the first embodiment. The composite cable 1A shown in FIGS. 1 and 2 is, for example, a cable capable of supplying power or grounding and transmitting an electric signal.

As shown in FIGS. 1 and 2, the composite cable 1A includes a first conductor cable 20A, a second conductor cable 30A, a cable 3A, and a connecting portion 6A.

The first conductor cable 20A is composed of a conductive member 2A and a jacket 4A. The second conductor cable 30A is composed of a conductive member 2A and a jacket 7A. The conductive member 2A is made of a material having conductivity. When the composite cable 1A is adopted as a trunk line or a branch line of a wire harness, the conductive member 2A can function as, for example, a power cable for power transmission or a ground cable for grounding.

Specifically, the conductive member 2A is a solid single wire (metal wire) made of a metal material. The conductive member 2A has, for example, a cross-sectional viewing angle shape (rectangular shape). The conductive member 2A may be any metal material having a conductive property, and metal materials such as aluminum, copper, copper alloy, tin-plated wire, iron, and nickel can be exemplified.

The outer covers 4A and 7A are made of an insulating material that covers the outer peripheral surface of the conductive member 2A. Examples of the insulating material include polyethylene, PVC, nylon, silicon and the like. For example, the jackets 4A and 7A are formed by extrusion molding. The outer covers 4A and 7A can integrally cover the outer peripheral surfaces of the conductive members 2A of the first conductor cable 20A and the second conductor cable 30A, which are arranged apart from each other in the cross-sectional direction of the composite cable 1A, for example. Shape, for example, rectangular in cross section.

The connecting portion 6A is connected to the outer cover 4A of the first conductor cable 20A and the outer cover 7A of the second conductor cable 30A. The connecting portion 6A is arranged adjacent to each of the first conductor cable 20A and the second conductor cable 30A in the cross-sectional direction. The connecting portion 6A has a predetermined distance between the first conductor cable 20A and the second conductor cable 30A in the cross-sectional direction so that a cable 3A or the like can be arranged on the upper portion 61A, and a smooth region is formed. It is formed like this. In the connecting portion 6A, the lower portion 62A, which is the opposite surface of the upper portion 61A, forms a continuous smooth surface with the lower surface portion 44A of the first conductor cable 20A and the lower surface portion 74A of the second conductor cable 30A. Further, the connecting portion 6A is formed so that the length in the extending direction is longer than the length in the extending direction of the upper portion 41A of the first conductor cable 20A or the upper surface portion 71A of the second conductor cable 30A. The connecting portion 6A is formed so as to extend together with the first conductor cable 20A and the second conductor cable 30A in the extending direction. The connecting portion 6A may be formed thinner than the thickness of at least one of the outer covers 4A and 7A of the first conductor cable 20A and the second conductor cable 30A in the cross-sectional direction.

The connecting portion 6A is made of an insulating material like the outer covers 4A and 7A. Examples of the insulating material include polyethylene, PVC, nylon, silicon and the like. For example, the connecting portion 6A is formed by extrusion molding like the outer covers 4A and 7A. That is, the connecting portion 6A may be integrally formed with, for example, the outer cover 4A of the first conductor cable 20A and the outer cover 7A of the second conductor cable 30A. The connecting portion 6A is formed separately from the outer cover 4A of the first conductor cable 20A and the outer cover 7A of the second conductor cable 30A, and is attached to the outer covers 4A and 7A by an appropriate method such as adhesion or welding. It may be connected.

The cable 3A is arranged above the connecting portion 6A, for example, in an unrestrained state. The cable 3A is a linear body here. The cable 3A is, for example, a communication cable, and more specifically, an optical fiber core wire. When the composite cable 1A is adopted as a trunk line or a branch line of a wire harness, the cable 3A can function as, for example, a communication cable for signal transmission. Here, in addition to the communication cable, a power cable, a ground cable, or the like may be arranged above the connecting portion 6A.

Although FIG. 1 illustrates a case where an optical fiber core wire as two cables 3A is accommodated in the upper portion 61A of the connecting portion 6A, the cable 3A accommodated in the upper portion 61A of the connecting portion 6A is illustrated. The number of the above is not particularly limited. That is, the number of cables 3A accommodated in the upper portion 61A of the connecting portion 6A may be one or three or more. Hereinafter, an example in which the cable 3A is a communication cable will be described.

FIG. 3 is a cross-sectional view of an optical fiber core wire as a communication cable 3A.
As shown in FIG. 3, the optical fiber core wire as the communication cable 3A has a core 101, a clad 102, a fiber wire coating 103, a cushioning material 104, and an outer jacket 105. The core 101 and the clad 102 are made of, for example, quartz glass or resin. The outer diameter of the clad 102 can be equal to or smaller than 125 micrometers commonly used in communication applications, for example 80 micrometers (including an error of ± 5%). By reducing the outer diameter of the clad 102, the bending strain of the optical fiber is reduced, and the breaking probability can be reduced. However, if the outer diameter of the clad 102 is made too small, it becomes necessary to reduce the core size, and the connection loss tends to increase.

The fiber wire coating 103 is made of an ultraviolet curable resin, a thermosetting resin, or the like. For example, in the case of in-vehicle use, it is made of silicon acrylate or the like in consideration of heat resistance.

The cushioning material 104 is a member arranged around the fiber wire coating 103 in order to increase the strength against the tensile force applied in the longitudinal direction of the optical fiber. The cushioning material 104 is composed of, for example, a plurality of fibers and is arranged on the entire circumference of the fiber wire coating 103. Examples of the fiber include aramid fiber and the like. The outer jacket 105 is preferably made of, for example, nylon or fluororesin (for example, ETFE). The outer diameter of the outer jacket 105 is preferably 1 mm or less, for example, 800 to 900 micrometers, and is appropriately configured with a desired value. By reducing the outer diameter of the outer jacket 105, the optical fiber core wire becomes easy to bend, which leads to improvement in the wiring property. However, if the outer diameter of the outer jacket 105 is made too small, the protection from the external force becomes insufficient, and the transmission loss tends to increase.

In the composite cable 1A, the communication cable 3A may be, for example, a metal wire (metal wire). In this case, the communication cable 3A is, for example, a twisted wire, a shielded wire, a coaxial cable, or the like, and may be a cable provided with a twisted wire and a jacket covering the outer periphery thereof.

FIG. 4 is a perspective view showing a state in which the connecting portion 6A of the composite cable 1A according to the first embodiment is folded back toward the first conductor cable 20A. As shown in FIG. 4, the composite cable 1A has an outer cover 4A of the first conductor cable 20A by folding back the end of the connecting portion 6A on the second conductor cable 30A side toward the first conductor cable 20A. It is formed so that it can cover at least a part of. Specifically, in the composite cable 1A, the upper portion 61A of the connecting portion 6A is folded back toward the upper portion 41A of the first conductor cable 20A, and the outer surface portion 43A of the outer cover 4A of the first conductor cable 20A and the second conductor cable 30A. The outer cover 7A can be arranged so as to be adjacent to the inner side surface portion 72A. As described above, the connecting portion 6A is folded back so that the outer surface portion 43A of the first conductor cable 20A is adjacent to the inner side surface portion 72A of the second conductor cable 30A in the cross-sectional direction, thereby forming a space extending in the extending direction. Will be done. For example, each communication cable 3A is arranged so as to be movable in space. The outer surface portion 43A of the first conductor cable 20A and the inner side surface portion 72A of the second conductor cable 30A may be in contact with each other or may be separated from each other. Further, in FIGS. 1 and 4, the lower surface portion 74A of the outer cover 7A of the second conductor cable 30A is thicker than the surface of the other outer cover, which is similar to that of the composite cable of FIG. This is an example in which the lower surface portion 44A of the first conductor cable 20A and the upper surface portion 71A of the second conductor cable 30A are set to substantially the same height position on the premise that the first conductor cable 20A is folded back to the same height. For example, all the surfaces of the outer cover may have the same thickness. These matters also apply to the following examples.

The composite cable 1A includes a holding portion 63A that holds the connecting portion 6A in a folded state. The holding portion 63A engages, for example, by adhering the upper portion 61A of the connecting portion 6A and the upper portion 41A of the outer cover 4A of the first conductor cable 20A with an engaging member such as an adhesive member. The holding portion 63A may weld the upper portion 61A of the connecting portion 6A and the upper portion 41A of the outer cover 4A of the first conductor cable 20A. Further, the holding portion 63A may engage the upper portion 61A of the connecting portion 6A and the upper portion 41A of the outer cover 4A of the first conductor cable 20A with a hook-and-loop fastener or an adhesive tape.

According to the composite cable 1A having the above-described configuration, the connecting portion connected to the outer cover 4A of the first conductor cable 20A and the outer cover 4A of the second conductor cable 30A and arranged adjacent to each other in the cross-sectional direction. 6A and. With this configuration, the composite cable 1A is used as a power cable or a ground cable by arranging at least one communication cable 3A arranged in the connecting portion 6A and folding back the connecting portion 6A. It is possible to easily produce a composite cable 1A including a first conductor cable 20A, a second conductor cable 30A, and a communication cable 3A.

Therefore, according to the composite cable 1A having the above-described configuration, the productivity can be improved.

Further, according to the composite cable 1A, the first conductor cable 20A and the second conductor cable 30A having the conductive conductive member 2A and the connection arranged adjacent to the first conductor cable 20A and the second conductor cable 30A. Since it has at least one communication cable 3A housed in the space surrounded by the part 6A, for example, power supply or grounding by the first conductor cable 20A and the second conductor cable 30A, and light as the communication cable 3A. Optical signal transmission via fiber can be realized with a single cable.

Further, since the communication cable 3A is housed in the space surrounded by the connecting portion 6A, even when an external force is applied to the outer covers 4A and 7A of the composite cable 1A and the connecting portion 6A, the communication cable 3A has an external force. It is difficult for an external force to act directly. In particular, since the connecting portion 6A is formed thinner than the outer cover 4A, 7A of at least one of the first conductor cable 20A and the second conductor cable 30A in the cross-sectional direction, the outer cover 4A of the composite cable 1A , Even if an external force is applied to 7A, the external force is first applied to the first conductor cable 20A or the second conductor cable 30A and then applied to the communication cable 3A, so that the external force is directly applied to the communication cable 3A. Hard to work. As a result, it is possible to suppress an adverse effect on signal transmission by the communication cable 3A due to an external force applied to the communication cable 3A.

In addition, when the communication cable 3A is housed in the space surrounded by the connecting portion 6A in an unconstrained state, that is, the communication cable 3A is provided with a space between the upper portion 61A of the connecting portion 6A and the communication cable 3A. When the communication cable 3A is arranged in a movable state, even if the connecting portion 6A is deformed by an external force, the communication cable 3A moves in the connecting portion 6A and an external force is applied to the communication cable 3A. It is possible to avoid this.

Further, according to the composite cable 1A, since the outer covers 4A and 7A and the connecting portion 6A are formed of a flexible insulating member, the connecting portion 6A may be plastically deformed when the composite cable 1A is curved. This makes it possible to improve the bending performance of the composite cable 1A. Further, since the composite cable 1A has a flat shape such as an ellipse or an oval in cross section, the flexibility in the short axis direction is improved as compared with a circular cable of the same material and the same cross-sectional area, and the vehicle. The ability to route to is improved.

Further, by using the optical fiber as the communication cable 3A, the signal transmission in the communication cable 3A is less likely to be adversely affected by the first conductor cable 20A and the second conductor cable 30A as the power supply line and the electromagnetic waves generated outside.

As described above, according to the composite cable 1A according to the first embodiment, it is possible to provide a cable having sufficient performance as a wire harness.
