Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to plug-in wiring.

[0002]

[Prior art]

 With the sophistication of electronic products, the miniaturization and miniaturization of electronic parts and assembly parts, which represent leading-edge technology, have become the trend of the times. For this reason, the trends of electronic products are being followed or leading the trends of electronic products, and electronic parts and assembly parts are developing with the goal of reducing the occupied volume (downsizing) and manufacturing costs.

Since circuits of electronic parts and assembled parts are extremely complicated, signals are transmitted using wiring. Circuits of electronic parts and assembly parts are connected by bus wiring.

[0004]

[Problems to be solved by the invention]

 However, it is difficult to manufacture the connecting terminal portion of the wiring with high accuracy in response to the precision and miniaturization of electronic parts and assembly parts, and the manufacturing cost tends to rise relatively.

Further, in the conventional plug-in wiring shown in FIG. 5, the thermoplastic insulating coating material 11 and the signal line (wiring) 12 are individually mass-produced, and the insulating coating material 11 is divided into two to form the signal line 12. Are sandwiched in between, and the insulation coating material 11 is integrated by pressure bonding.

However, according to this method, a void W is likely to be formed in the contact surface between the insulating coating material (insulating coating layer) 11 and the signal line 12, and the signal line 12 made of a copper wire is easily separated from the insulating coating layer 11. Further, there is a possibility that a problem such as deterioration of signal transmission quality or poor contact may occur due to the oxide film generated by contact with air. On the other hand, since the insulating cover layer 11 and the signal line 12 are separately manufactured, there is a problem that the cost for additional man-hours increases. Further, since the number of signal lines 12 forming the plug-in wiring is set at the time of manufacturing, the flexibility at the time of application is poor.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a plug-in wiring which has high quality, can reduce manufacturing cost, and is excellent in applicability. And

[0014]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the plug-in wiring according to the present invention, FIG. 2 is a sectional view of the plug-in wiring, and FIG. 3 is formation of an insulating coating layer of the plug-in wiring. FIG. 4 is a schematic diagram for explaining the process, and FIG. 4 is an explanatory diagram for explaining the tear groove portion.

As shown in FIGS. 1 and 2, the plug-in wiring according to the present invention includes a plurality of flat copper wires 21 to 23 which are signal wires (wirings) which are arranged in parallel and extend in the longitudinal direction. An insulating coating layer 3 made of a synthetic resin such as vinyl chloride (PVC) and a fixing member 4 made of a synthetic resin such as polyvinyl chloride (PVC) for fixing the connection terminal portion 29 for insertion. .

The insulating coating layer 3 is formed by integral extrusion molding so as to cover the surfaces of the flat copper wires 21 to 23, and extends in the longitudinal direction at a position located between the flat copper wires 21 to 23. It has concave groove portions 31 to 33 for tearing.

The integral extrusion molding is performed, for example, as shown in FIG. That is, the plurality of flat copper wires 21 to 23 are introduced into the extrusion die 52 of the extruder via the guide roll 51. Then, it is integrated with a thermoplastic resin (not shown) that is a raw material of the insulating coating layer, the surfaces of the flat copper wires 21 to 23 are covered with the thermoplastic resin to form the insulating coating layer, and the groove for tearing is formed. It is formed and extruded at the same time. After that, it was introduced into a water tank for cooling, and plug-in wiring was obtained.

Therefore, the contact surfaces of the insulating coating layer 3 and the flat copper wires 21 to 23 are in close contact with each other, and it is difficult for voids to be generated, and the oxide film generated by the contact with air lowers the transmission quality of signals or Since problems such as poor contact do not occur, it is possible to obtain high quality products.

Further, the tear groove portions 31 to 33 extending in the longitudinal direction are applied by tearing and separating an appropriate groove portion when using the plug-in wiring as shown in FIG. Since it is possible to obtain plug-in wiring having the number of flat copper wires corresponding to the number of connection terminals of the connector section, it is excellent in applicability.

Further, since the insulating coating layer is formed in a single process, the cost for additional man-hours is unnecessary as compared with the conventional case including a plurality of processes. It is possible to reduce the manufacturing cost.

On the other hand, a fixing member 4 for fixing the wiring terminal portion 2 is attached to the wiring terminal portion 29 for inserting and connecting the flat copper wires 21 to 23, and the connection can be made easily and accurately. It is possible to obtain high quality products.

Further, the thickness A of the insulating coating layer of the tear groove portions 31 to 33 is calculated from the thickness B of the insulating coating layer between the flat copper wires 21 to 23 and the tear groove portions 31 to 33. , So that it is thin. In other words, since the strength of the groove is relatively weak, it is easier to preferentially tear and separate the groove, and after tearing, the flat copper wire is exposed and does not come off. , Can be surely prevented.

The present invention is not limited to the above-described embodiment, but can be variously modified within the scope of the utility model registration claim.

[Effect of the invention]

 As described above, according to the present invention, the following effects can be obtained by the configurations described in the respective claims.

According to the first aspect of the invention, since the insulating coating layer formed by integral extrusion molding and the contact surface of the flat copper wire are in close contact with each other, voids are unlikely to occur, and oxidation generated by contact with air is generated. The film does not cause problems such as deterioration of signal transmission quality or poor contact, and the connection terminal part for inserting the flat copper wire is fixed by a fixing member, so it is easy and accurate. Since they can be connected, it is possible to obtain high quality products. Further, since the insulating coating layer covering the flat copper wire is formed by integral extrusion molding, the cost for additional man-hours is not necessary and the manufacturing cost can be reduced. Further, when used, the plug-in wiring having an arbitrary number of connection terminals can be obtained by tearing and separating an appropriate concave groove portion, which is excellent in applicability.

According to the second aspect of the invention, since the thickness of the insulating coating layer of the concave groove portion is smaller and thinner than the thickness of the edge coating layer between the flat copper wire and the concave groove portion, the strength of the concave groove portion is high. , It becomes relatively weak, and it is possible to easily tear and separate the concave groove portion preferentially, and it is possible to reliably prevent the flat copper wire from being exposed and coming off after tearing. It is possible.
