Description

  The present invention relates to a method for bundling a plurality of conductors, a wire harness for bundling the conductors, and a portable communication terminal including the wire harness.

In general, in various electric and electronic devices, a plurality of conductive wires arranged in a casing are used as wiring.
This type of conducting wire needs to be arranged with an effective route so as to pass between various components in a narrow internal space as the equipment is downsized.
For this reason, as shown in FIG.9 and FIG.10, according to the prescription | regulation of a path | route, bundling the conducting wire 1 and bundling several places with the heat contraction tube 2 are performed (for example, refer patent document 1).
And as shown in FIG. 11, the wire harness 3 which bundled the some conducting wire 1 is engaged with the engaging part 5 shape | molded in the housing | casing 4 which comprises an apparatus, and a path | route is specified in the case 33. However, it is incorporated in the equipment.

In particular, in a device including a plurality of housings 4, the wiring path is not only three-dimensionally complicated, but also the wire harness 3 is damaged at the edges of the housing holes and wiring boards through which the wire harness 3 passes. Therefore, as shown in FIG. 12, the heat-shrinkable tube 2 is attached to and protected from the portion that easily contacts the edge 6 portion.
JP 9-161546 A

By the way, as described above, even if a plurality of portions of the plurality of conductive wires 1 are bundled by the heat shrinkable tube 2, the entire shape of the wire harness 3 is not determined, and therefore, wiring is performed in the casing 4 constituting the device. In such a case, it must be stored in a predetermined wiring route while being manually shaped, which requires a large number of assembly steps.
In addition, in a portion where the wiring path cannot be defined, a plurality of conductors 1 are bent freely and cannot be held at a fixed position, so that noise due to an electrical signal generated from each conductor 1 affects the circuit components in the housing 4. The applied level becomes unstable and stable electrical characteristics cannot be secured.
In addition, since the overall shape of the wire harness 3 is not determined, the wires 1 are entangled with each other when packed and transported as a part or assembled into the housing 4, and it takes time and effort to loosen the wires. Would require further assembly man-hours.

  The present invention has been made in view of the above circumstances, and provides a method of bundling a conductive wire, a wire harness, and a portable communication terminal capable of wiring a conductive wire without damage with as few assembly man-hours as possible and obtaining stable electrical characteristics. The purpose is to do.

  In order to achieve the above object, a method for bundling a conductive wire according to the present invention is a bundling method for bundling a plurality of conductive wires, wherein the plurality of conductive wires are integrated and bundled together with a resin, A member that can be positioned with respect to the housing is integrally formed with the plurality of conductive wires with resin.

Moreover, the method for bundling the conducting wire of the present invention is characterized in that the member is integrally molded at a bending point formed in the extending direction of the conducting wire.
Furthermore, the conducting wire is characterized in that it is formed in a so-called three-dimensional shape in which at least one set of positional relationships of the bending points is displaced three-dimensionally.

  Moreover, the wire harness of the present invention is a wire harness having a plurality of conductive wires, wherein the conductive wires are bound by any one of the above-described methods for binding conductive wires.

  Furthermore, the portable communication terminal of the present invention is characterized in that various electrical components are wired by the above-described wire harness.

According to the method for binding conductive wires of the present invention, the conductive wires are integrated and bundled with resin, and further, the positioning member is integrally molded. Therefore, by integrating the conductive wires into a shape along the wiring path, By simply fixing the member to the substrate or the housing, it can be very easily attached to the determined wiring path, and the number of assembly steps can be minimized.
In addition, since the conductor can be securely placed in the wiring path in the housing, the conductor does not move in the housing, thereby stabilizing the level at which the noise caused by the electrical signal emitted from the conductor affects the circuit components. And stable electrical characteristics can be ensured.

  In particular, by providing the member at the bending point of the conducting wire, the conducting wire can be reliably supported at a predetermined position when mounted in the housing.

  Also, when used in mobile communication terminals where the wiring route is a three-dimensional complicated shape and wiring work is difficult, the conductor is made of resin in accordance with the three-dimensional complicated shape that bends the conductor at multiple locations. By bundling and forming, it can be easily mounted along a complicated wiring path.

  Furthermore, according to the wire harness of the present invention, since it can be made into a predetermined shape by the resin, it can be aligned when packed and transported as a part, and when transported or incorporated into a housing, Problems such as entanglement of the conductive wires can be eliminated, the assembly work can be performed smoothly, and the number of assembly steps can be further reduced.

  And according to the mobile communication terminal of the present invention, the wire harness in which the conducting wire is integrated with the resin is securely positioned or fixed to the housing by the member and wired along the complicated wiring path, so that it is stable. Electrical characteristics can be obtained, and there are no problems such as damage to the conductors, and the reliability can be improved.
