FIG. 1 is a partial schematic diagram of a flat parallel line according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of the flat parallel line of FIG. 1 . Please refer to Figure 1 and Figure 2 at the same time. In this embodiment, the flat parallel wire 100 includes at least two wires 110 that are combined side by side with each other. Here, four wires 110 are used as an example. These wires 110 are combined side by side by hot pressing or the like, as shown in FIG. 1 . As shown, the four wires 110 shown are substantially coplanar.

FIG. 3 is a schematic diagram of the components of the core wire of FIG. 2 . Please refer to FIG. 2 and FIG. 3 at the same time. In this embodiment, each wire 110 includes at least three bundles of core wires 112 and insulating materials 111 . The bonding parameters between the core wire 112 and the core wire 112 can be appropriately adjusted to adjust the relative position between the two. In another embodiment, the insulating material can cover the outer surface of the core wire 112 without gaps. The aforementioned hot pressing is for the insulating material 111 , so that the adjacent insulating materials 111 can be combined side by side with each other. Furthermore, the insulating material 111 is selected from materials that do not drop chips, so that the flat parallel wire 100 is advantageously used in an environment such as a clean room. In addition, each core wire 112 is formed by twisting a plurality of yarns 112a and a plurality of conducting wires 112b. Here, the yarn 112a is, for example, a polyurethane fiber, which has better tension and toughness. After twisting and weaving it, the central structure of the core wire 112 is formed, which can effectively improve the physical properties of the yarn 112a. It directly reacts to the core wire 112 , that is, the core wire 112 has the resistance to withstand dynamic bending.

The wire 112b is a bare copper wire or a bare copper wire with an outer coating (for example, a tinned copper wire, that is, the outer surface of the bare copper wire has a metal coating). Here, the form of the wire 112b can be determined by selecting a corresponding copper material according to the usage state, required structural strength and impedance. Furthermore, the wire 112b is twisted around the outer periphery of the yarn 112a as a medium for electrical transmission, but since the wire 112b is substantially attached to the outside of the yarn 112a, Therefore, in terms of structural composition, it does not need to bear too much stress caused by dynamic bending, and thus its service life can be improved accordingly.

Referring to FIG. 2 again, in the present embodiment, the outer diameter D2 of each wire 110 is 0.5 mm to 2.5 mm, and the preferred one is 1.725 mm to 1.745 mm. The thickness of the insulating material 111 is 0.2 mm to 0.6 mm. The outer diameter of each core wire 112 is 0.5 mm to 0.6 mm. Accordingly, when the four wires 110 are combined to form the flat parallel wire 100 , the width D1 of the flat parallel wire 100 is 4.8 mm to 10 mm, and the preferred value is 6.9 mm to 6.98 mm. The flat parallel wire 100 shown in this way can be applied to different movable parts of various automatic machines and occupies less space, and due to the characteristics of the aforementioned core wire 112, it can freely deform and maintain its planar shape while maintaining its planar shape. Flat and parallel in shape 100.

Please refer to FIG. 2 again. It should also be mentioned here that the core wires 112 of the present embodiment are distributed at an equal angle with respect to the central axis C1 of the electric wire 110 in the insulating material 111 . Three bundles of core wires 112 are shown here, so The axes of any two adjacent core wires 112 have a central angle of 120 degrees relative to the central axis C1. This allows the core wires 112 to share the stress close to each other when the wire 110 is in a dynamic bending state, so as not to cause stress concentration to cause damage to the wire 110 . In addition, the number of bundles of the core wires 112 in one electric wire 110 can be selected from 3 to 7 bundles under the premise of conforming to the aforementioned range of the outer diameter D2 of the electric wire 110 (1.2 mm to 2.5 mm).

FIG. 4 is a simple schematic diagram of the flat parallel wire of FIG. 1 performing a bending resistance test. Referring to FIG. 4 , due to the aforementioned component characteristics, the bending resistance of each wire 110 in this embodiment is that the number of dynamic bending times is greater than 10 million times, and the bending radius R1 is 0.5 mm to 30 mm , wherein the bend can be a U-shaped bend or a V-shaped Bend. In this way, the flat parallel wire 100 can withstand the operating environment of repeated dynamic bending. Taking the wire 110 shown in FIG. 4 as an example, one end P1 is a fixed end, and the other end P2 is a moving end, which represents the reciprocating movement of the automatic equipment during operation, so that at least a partial area of the wire 110 is bent. folds, and as the time sequence increases, the folds are formed in different parts.

To sum up, in the above-mentioned embodiments of the present invention, the flat parallel wire is formed by combining at least two wires side by side with each other, wherein each wire includes at least three bundles of core wires and an insulating material, and the insulating material is wrapped outside the core wires , and each core wire is twisted by a plurality of yarns and a plurality of wires, and the wires are wound outside the yarns. Accordingly, for the core wire, the yarn with extensibility and toughness is used as the central structure, so that the structural strength of the core wire can be increased and the toughness thereof can be improved. Furthermore, the electric wire composed of at least three bundles of core wires can make the electric wire have the aforementioned characteristics accordingly. The flat parallel wire formed by combining multiple wires side by side can have higher resistance to deflection due to the aforementioned characteristics, and thus can withstand the operation situation of dynamic repeated bending, which can meet the requirements of modern production lines. need.

In other words, the flat parallel wire created by the present invention gathers a plurality of parallel wires, and due to the characteristics of the aforementioned core wire, it has a large degree of freedom in the direction of bendability or flexibility, and has high resilience. Therefore, the flat bundling wire can be freely bent or deflected along with the movable parts of the automation equipment, and can easily return to the original undeformed flat bundling wire during the reciprocating movement.
