【考案の詳細な説明】 「産業上の利用分野」 本考案は、電気機器等の内部配線や自動車の配線用とし

に使用する耐屈曲性圧接電線に関するものである。[Detailed Description of the Invention] "Industrial field of application" The present invention is intended for internal wiring of electric devices or wiring of automobiles, and is used for connecting an insulation displacement terminal to movably wire an intermediate portion. The present invention relates to a flexible press-connecting electric wire.
「従来の技術」 一般に、電線に耐屈曲性を付与する手段として、下記の
二様のものがある。即ち、その一つは導線を細線化して

状に配線されている。"Prior Art" Generally, there are the following two means for imparting flex resistance to an electric wire. That is, one is a thin wire twist structure in which conductors are thinned into a group and the thin wire group is twisted to form an electric wire, and the other one is disclosed in Japanese Utility Model Publication No. 58-133215. In addition, there is a twisted structure with a reinforcing string that twists several thin wire conductors centered around a tough and flexible aramid fiber string, and these bend resistant wires are used for internal wiring of electrical equipment etc. The middle of the wiring is movably arranged so that it can be repeatedly moved.

接端子に使用できないものとされている。"Problems to be solved by the invention" Among the flex-resistant electric wires of the conventional structure described above, the former thin wire twisted structure has "twisted" due to pressure contact resistance when pressure-contacted to the U-shaped slot of the pressure-contact terminal. Therefore, the contact property with the pressure contact terminal is not good, and moreover, "twisting collapse" progresses over time, and the pressure contact state gradually deteriorates, so that it cannot be used for the pressure contact terminal.

In addition, there is a problem that the wire diameter becomes significantly thicker than that of a normal wire having the same conductor area (a wire in which cords are not twisted).
本考案は、以上の従来構造の不具合点を解消する耐屈曲
性圧接電線を提供するものである。The present invention provides a bending-resistant pressure-welded electric wire which eliminates the above-mentioned problems of the conventional structure.

The shape is such that it is in close contact with the inside of each thin wire conductor group. The outer peripheral compression is preferably performed at a compression ratio of 80% to 95%, which is the outer diameter ratio of the "outer diameter after plastic deformation" to the "outer diameter of the bare electric wire".

When pressure-bonded to the pressure-contact terminal, "twist collapse" does not occur and good contact with the pressure-contact slot is obtained, and the contact is stable without change over time.
Further, since the twisted structure of the thin wires around the reinforcing cord is maintained, the bending resistance due to the twisted structure of the thin wires and the physical strength such as the breaking strength due to the reinforcing cord are secured.

線化をもたらす特有作用がある。Furthermore, the reinforcing cord present in the center exhibits a parasol outer edge shape of continuous concave curved surface that closely contacts the inside of each thin wire conductor group due to the pressing force at the time of plastic deformation of the outer circumference of the wire, and Since the voids between the reinforcing cords are embedded, the plastic deformation of the outer periphery and the embedding of the voids prevent the wire from being significantly thickened due to the presence of the reinforcing cords. That is, in the bending-resistant pressure-bonded electric wire of the present application, "the inner portion of the thin wire conductor forming the outer periphery is the portion in contact with the reinforcing cord of the soft center material without being plastically deformed", and the reinforcing cord has the "parasol outer edge shape" However, the bending resistance and flexibility of the bending-resistant electric wire are not impaired, and the relative joining posture between the soft center material and the hard outer peripheral material is stable, and there is a specific action that leads to the thinning of the electric wire.

Referring to FIG. 1 showing an embodiment of the present invention, a bending resistant pressure-bonded electric wire 1 of this embodiment has an extra fine wire of “0.12 Ta × 8” on the outer circumference of a reinforcing cord 2 of aramid fiber (380 denier). The conductor wires 3 are arranged and twisted to form a unit electric wire 4 having an outer shape D 1 , the outer periphery of the unit electric wire 4 is pressed, and the outer periphery of the assembly of the ultrafine conductor wires 3 is plastically deformed to form the outer conductor D 4 . It has a circular outer circumference. And
The cross section of the reinforcing cord 2 is such that the concave curved surfaces 5 are continuous and exhibit a substantially octagonal parasol outer edge shape, and each concave curved surface 5 is in close contact with the inside of each ultrafine conductor wire 3.

With the reinforcing cord 2 as the center, an ultrafine conductor wire group 3 is arranged on the outer periphery thereof, and a die is forcibly passed while being twisted by a twisting machine, and the outer periphery is plastically deformed by the forced passage of the die, and FIG. 1 (A). After that, the insulating coating 6 is formed on the outer periphery thereof to obtain the shape of FIG. 1 (B).

The parasol outer edge-shaped reinforcing cord 2 consisting of a series of concave curved surfaces 5 along the inner curved surface is closely sealed, so the stability of the twisted shape by the reinforcing cord 2 and the ultrafine conductor 3 is extremely good, and the pressure welding is performed. When pressed against the terminal 7, as shown in FIG.
Good contactability is ensured without the occurrence of "twisting", and there is no risk of "twisting" over time.

施例の耐屈曲性圧接電線の破断力は8.4kg）。The plastic deformation occurs only on the outer periphery that is forcedly passed through the die, and the inside of each of the ultrafine conductors 3 that is in contact with the flexible reinforcing cord 2 pushes the reinforcing cord 2 to leave the reinforcing cord 2 in the void portion. Since the inner portion of the reinforcing cord 2 is maintained in its original shape, the twisted structure in which the ultrafine conductors 3 are arranged around the reinforcing cord 2 is maintained and is based on the twisted structure. The bending resistance of the entire electric wire is ensured within a necessary range, and the physical strength such as the breaking force of the electric wire due to the presence of the reinforcing cord 2 is sufficiently ensured (see FIG. Breaking force is 8.4kg).
そして、前記圧縮比による縮径によって、電線の太線化
が抑止され、同一導体断面積の通常電線と対比した太線
化度は小幅に止められる。Then, the diameter reduction due to the compression ratio suppresses thickening of the electric wire, and the degree of thickening of the electric wire in comparison with a normal electric wire having the same conductor cross-sectional area is kept to a small width.

域が好ましい。In addition, the compression ratio in the present invention is defined as "diameter of the reinforcing cord 2
As a result of confirming in a trial example in which various conditions such as the wire diameter and the number of extra fine wires 3 "are combined, when the compression ratio is 80% or less, the reinforcement string 2 is" extruded "due to excessive processing and is twisted. In addition, at a compression ratio of 95% or more, "twisting collapse" occurs at the time of pressure welding due to insufficient workability, and in the twisted structure that is usually expected as a pressure welding wire, the region of compression ratio = 80% to 95% preferable.
