Description

TECHNICAL FIELD The present invention relates to an insulated wire in which a conductor is covered with an insulator.

As an insulated wire, one using a rectangular conductor is known (for example, Patent Document 1). According to this, it is possible to reduce the wiring space as compared with the one using the round electric wire. Moreover, according to this, since flexibility is small, when fixing an insulated wire to a wall surface etc., the fixed part can be reduced compared with the round electric wire which twisted several strands together.

However, there are cases where it is desired to bend or bend the insulated wire. In this respect, the one using the rectangular conductor is not convenient. Therefore, an insulated wire in which a plurality of conductor foils that can rub against each other are laminated has been proposed (for example, Patent Document 2). According to this, flexibility in the stacking direction can be improved.

However, in the insulated wire described in Patent Document 2, the flexibility in the direction perpendicular to the stacking direction is also increased, and the effect of reducing the number of fixing points when fixing to the wall surface is impaired.

EMBODIMENT OF THE INVENTION Hereafter, although embodiment which actualized the insulated wire of this invention is described using drawing, the technical scope of this invention is of course not limited only to this. Note that detailed descriptions of well-known techniques are omitted. In this specification, when an insulated wire is referred to as an upward or downward direction, a rightward direction, or a leftward direction, it means the up, down, left, or right direction when FIG. 1 is viewed from the front.

(embodiment)
First, the configuration of an insulated wire 1 that is an embodiment will be described with reference to FIGS. 1 to 5. FIG. FIG. 1 is an explanatory view showing an insulated wire 1 of this embodiment. FIG. 2 is an explanatory diagram showing the structure of a single-wire conductor.

As shown in FIG. 1 , the insulated wire 1 is mainly composed of a single wire conductor 11 and an insulator 12 . In FIG. 1, the length of the insulated wire 1 is drawn short due to space limitations, but it is actually longer, for example, several tens of meters.

As shown in FIG. 2, the single-wire conductor 11 is formed by alternately performing mountain folds and valley folds at equal intervals on a long conductive metal thin plate 111 so that folds are formed along the longitudinal direction. A plurality of partitioned portions 114 partitioned by respective folds 112 and 113 are overlapped in a bellows shape. In FIG. 2, the thin conductive metal plate 111 is depicted as having no thickness for the sake of clarity of explanation, but in reality the partitions 114 are in close contact with each other as shown in FIG. Also, not all of the folds and compartments are labeled.
In FIG. 2, the length of the single-wire conductor 11 is shown to be short due to space limitations, but it is actually longer, such as several tens of meters.

The thickness of the conductive metal thin plate 111 is desirably 0.05 mm to 0.1 mm, and the number of partitions 114 is desirably 50 or more. 1 and 2, the thickness of the conductive thin metal plate 111 and the number of partitions 114 are not depicted faithfully for convenience of explanation. The height is 0.07 mm and the number of compartments 114 is 100.

The conductive thin metal plate 111 can be made of a metal foil that is a good conductor, such as copper foil or aluminum foil. In this embodiment, an electrolytic copper foil is used, which provides a uniform thickness.

FIG. 3 is an explanatory diagram showing the bending direction (laminating direction) of a single-wire conductor. FIG. 4 is an explanatory diagram showing the bending direction of the single-wire conductor (the direction perpendicular to the stacking direction).
The single-wire conductor 11 can be bent and bent in the direction of the arrow shown in FIG. 3, that is, the stacking direction, but it cannot be bent or bent in the direction of the arrow shown in FIG. 4, that is, the direction perpendicular to the stacking direction. is difficult. As a result, when the insulated wire 1 is fixed to a wall surface or the like, it is possible to reduce the number of fixing points and to bend it at a necessary place.

When the single-wire conductors 11 are connected to each other, the division portions 114 are alternately overlapped. At this time, the ends of the single-wire conductors 11 may be slightly opened and overlapped as they are. They may be alternately superimposed. In addition, regardless of which method is used, it is preferable to apply pressure so as to sandwich the outermost two partitions 114, 114 after overlapping. This pressure is preferably about 10 kg/cm ² . The connection between the single-wire conductors 11 can be applied not only when the single-wire conductors 11 are arranged on a straight line, but also when the single-wire conductors 11 are arranged at right angles.

When two books are alternately stacked one page at a time, they cannot be pulled off due to frictional force. However, when the partitioned portions 114 are alternately stacked, the same state occurs. etc., and can be treated with ordinary insulating tape.

In addition, by alternately overlapping the division portions 114, a large contact area can be ensured, and the electrical resistance at the time of connection between the single-wire conductors 11 can be reduced.

The insulator 12 is made of an insulating material and covers the single-wire conductor 11 . The insulator 12 has an inner side that is one size larger than the single-wire conductor 11 and has a plurality of protrusions 121 formed therein. The entirety of the insulator 12 is supported by the single-wire conductor 11 by the protrusion 121 coming into contact with the single-wire conductor 11 . This is because the flexibility of the single-wire conductor 11 is impaired if the entire inside is in close contact with the single-wire conductor 11 .

FIG. 5 is an explanatory diagram showing the configuration of the insulator. Note that the insulator 12 shown in FIG. 5 is obtained by cutting the insulator 12 shown in FIG.
The protrusion 121 may be a linear protrusion as shown in FIG. 5(a), or may be a dot-like protrusion as shown in FIG. 5(b). In addition, in FIG.5(b), the code|symbol is not attached|subjected to all the protrusion parts.

The contents described above are merely related to one embodiment of the present invention, and do not mean that the present invention is limited to the above contents.
