Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a wiring material used for wiring within and between devices such as electrical and electronic devices.

[Prior art]

Conventionally, a tape-shaped wiring material 3 as shown in FIG. It is used.

As shown in Figure 3, this means that there are multiple bodies l, 1= (
This is a single wire or one-wire conductor) coated with an insulator 2. When manufacturing the wiring material 3 having such a structure, the four long bodies (1) and (1) are continuously coated with thermoplastic resin by extrusion, or two types of plastic tape are continuously supplied. A common method is to cover the conductor 1.1 from above and below and bond them together. and,
When wiring the wiring material 3 thus formed between, for example, PIIWS, cut the wiring material 3 to the required length, and then strip off the insulator 2 at both ends.
The conductors 1, 1---- are exposed, and the cough conductor Ll- is connected to the necessary parts of the device by soldering or the like. Therefore, the four bodies 1.1
--- is tinned in advance for ease of soldering or to prevent corrosion of the surface.

Ki is applied.

By the way, in the conventional wiring material 3 shown in the third I2I, it is necessary to cut the wiring material 3 every time a connection is made and remove the insulator 2 from the terminal. There is a risk of attaching conductor 1 (U) when removing 11,
This terminal processing work requires attention and time. In addition, since it is not known in advance where the wiring material 3 will be cut,
The long conductor 1, including the parts that originally do not need to be plated, that is, the parts that are covered with the insulator 2 even after connection.
．． It is necessary to apply tin plating over the entire lengthwise direction of 1, so that there is no need to waste tin plating.

[Purpose of the invention]

In view of the above problems, the object of the present invention is to provide an insulator for the terminal portion of wiring material used for wiring between electronic devices! To provide a wiring material that does not require stripping work and does not require tin plating on unnecessary parts, that is, eliminates the waste of tin plating.

[Structure of the invention]

In order to achieve the above object, the wiring material of the present invention is a wiring material in which at least both end portions of a conductor are exposed and coated with an insulator, and wherein at least the portion of the conductor covered with the insulator is covered with an insulator. The conductor surface is characterized by no tin plating.

[Embodiments of the invention]

Embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an embodiment of the wiring material of the present invention.

As this figure shows, the present invention has six bodies 1.1-
are arranged parallel to each other in a plane at a predetermined interval, and covered with an insulator 2 with both ends of the four conductors 1 and 1- exposed, and at least one of the four conductors 1 and 1- is exposed. The portion where the insulator 2 is covered is not plated, leaving an exposed surface 1 on one end of the shoulder body l.
In this figure, m bodies IB and IB, which are exposed parts of shoulder body 1, are shown.
- Tin plating is applied only to the surface. of course,
In Figure 1, it goes without saying that tin plating may also be applied to the surface of conductors IA and IA-, which are the exposed parts of the other conductor that are not tin-plated. The tinned side is soldered, and the untinned side is fitted with a connector. Further, although there is a plurality of conductors 1 in FIG. 1, there is also a single conductor as shown in FIG. Furthermore, in FIG. 2, a portion of the conductor 1 is exposed at the center of the wiring member 3, and this exposed portion of the conductor IC is also plated with tin. Therefore, other wiring materials etc. can be connected to this four-piece tC portion by soldering. Further, in the case of FIG. 2, the cross-sectional shape can be changed to a round shape, a rectangular shape, or a polygonal shape depending on the place of use. Generally, the length of the wiring material 3 shown in FIGS. 1 and 2 is 10 to 50 cm. There are the following methods for manufacturing the wiring material 3 shown in FIG. 1. First, 7
The 19 conductors 1, 1 ---- with their tin-plated ends on the same side, are lined up parallel to each other at a predetermined interval on a plane, and then the 4 conductors 1 , (2) Two plastic tapes are placed on top and bottom so that both ends of -1 are exposed for a predetermined length, and the plastic tapes are heat-pressed using a heat-press roll or the like. Of course, adhesive may be applied to the adhesive surface of the plastic tape before bonding. Another method is to place the conductors 1.1-.- on the aligned portions in an injection mold. The insulator 2 may be formed by injection molding a plastic resin.

According to the wiring material of the present invention formed in this way, the shoulders of the length necessary for connection are exposed from the beginning at both ends of the wiring material. Insulators on both ends of the material! , lI removal work is not necessary, and connection work can be done extremely easily and in a short time. Moreover, tin plating, which is provided to facilitate soldering, is applied only to the solder connection parts that require tin plating, and is not applied to other parts, such as parts covered with insulators. Since there is no tin plating, there is no waste of tin plating. In addition, when using the wiring material of the present invention made in this way,
A unit method is adopted in which several standard length wiring materials are prepared and the wiring material is used in a length that corresponds to the required length. This point is a completely different feature from the conventional cutting method.

〔Effect of the invention〕

As described above, according to the wiring material of the present invention, there is no need to strip off the insulator at the terminal part of the wiring material used when wiring between electronic devices, etc., and the wiring material does not waste tin plating. can be obtained.
