DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulated wire used for electric wiring in household electric appliances and office automation equipment, or electric wiring across walls and floors in houses, for example. More specifically, the present invention relates to an insulated wire for obtaining electrical continuity by attaching with a screw at the time of wiring.

[0002]

2. Description of the Related Art Conventionally, this type of insulated wire includes
For example, as shown in FIG. 8, at the time of wiring, one end of the insulating material 2 of the insulated wire 1 is peeled off to expose one end of the conductive material 3. The first crimping portion 4b of the round terminal 4 having a round shape is wound and crimped by using a special tool, and the second crimping portion 4c of the round terminal 4 is wound around one end of the insulating material 2 and crimped. There is something. Then, a screw (not shown) is inserted into the screw insertion hole 4d of the fastening portion 4a, and the round terminal 4 is screwed to an appropriate position to obtain electrical continuity.

[0003] Some conventional insulated wires, for example, as shown in FIG.
The mold terminal 5 is connected to one end of the conductive material 3 in the same manner as described above.
In some cases, the crimping portion 5b is wrapped and crimped by using a special tool, and the second crimping portion 5c is wrapped around one end of the insulating material 2 and crimped.

[0004]

However, such a conventional insulated wire 1 requires a special tool for crimping the round terminal 4 and the Y terminal 5, and the round terminal 4 · Y
The reliability of the crimping between the mold terminal 5 and the conductive material 3 is required. Further, as shown in FIG.
Since a is deviated from the center of the cross section of the insulated wire 1, it is necessary to check the mounting direction when mounting with the screw. In addition, since the second crimping portions 4c and 5c are crimped to the insulating material 2 of the insulated wire 1, the outer diameter of the circular cross section is further increased, and it is difficult to mount the insulated wire 1 thinly at the time of wiring. Was.

SUMMARY OF THE INVENTION It is an object of the present invention to prevent the workability of an insulated wire during wiring from being deteriorated, and to make it possible to mount the insulated wire thinly.

[0006]

Therefore, an insulated wire 10 according to the present invention comprises a flat conductive material 11 having a plurality of screw holes 11a, as shown in the following embodiments, and the conductive material. 11 including the screw insertion hole 11a.
And an insulating material 12 that covers the metal .

[0007] In the insulated wire 10 of the first aspect, as shown in the following embodiment, a plurality of the conductive materials 11 are provided in parallel and insulated from each other. It is characterized by being integrally coated with the insulating material 12.

According to a third aspect of the present invention, as shown in the following illustrated embodiments, the insulating coated electric wire 10 according to the first aspect is characterized in that an adhesive 14 is provided on one surface of the insulating material 12. And

[0009]

When wiring, the insulating material 12 is peeled off to expose the screw insertion hole 11a of the conductive material 11, and the screw insertion hole 11a is removed.
a and insert the screw 13 into the screw mounting position.

According to the second aspect of the present invention, the plurality of conductive members 11 provide separate electrical continuity.

According to the third aspect of the present invention, the insulated wire 10 is attached to, for example, a wall surface or a floor surface with the adhesive material 14.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of one end of an insulated wire according to one embodiment of the present invention.

The insulated wire 10 includes a conductive material 11 and an insulating material 12. The conductive material 11 is made of a flat, narrow, metal plate having a predetermined length.
Are provided. Each of the screw insertion holes 11a is formed in a circular shape.

The insulating material 12 is provided so as to cover the entirety of the conductive material 11.

For example, when wiring is performed in an air purifier, the insulating material 12 at one end and the other end (not shown) of the insulated wire 10 is peeled off using a cutter, for example, as shown in FIG. Screw insertion hole 11a
To expose. Then, for example, if there is an uneven portion in the housing or a step in the mounting position, the insulated wire 1
0 is bent as shown in FIG. If there are irregularities in the housing or if there is a difference in the mounting direction, the insulated wire 10 is bent as shown in FIG. Then, the appropriately insulated wire 10 is provided along the concave and convex shape in the housing (not shown), and the screw 13 is inserted into the screw insertion hole 11a and screwed into the screw mounting position.

In the above-described embodiment, when wiring,
Peel off the insulating material 12 at both ends of the insulated wire 10,
The example in which the screw insertion hole 11a of the conductive material 11 is exposed and attached has been described. However, as shown in FIG. 4, the insulating material 12 at both ends of the insulated wire 10 is peeled off to expose the screw insertion hole 11a of the conductive material 11, and the insulating material 12 in the middle of the insulated wire 10 is removed. Partially peel off,
A plurality of screw insertion holes 11a of the conductive material 11 may be exposed and attached with screws 13, respectively. In this way, for example, when making a long assembly line, connection terminals can be easily formed at arbitrary length positions of the insulated wire 10 and, as in the conventional case shown in FIG. The troublesome work of screwing with the screw 21 while connecting the electric wires 1... Can be omitted.

In the illustrated embodiment, the screw insertion hole 11a has a circular shape. However, as shown in FIG. 5, the screw insertion hole 11a may be a long hole.

Further, in the illustrated embodiment described above, an example is shown in which one conductive material 11 is used. However, as shown in FIG. 7, two conductive materials 11 may be provided in parallel, insulated from each other, and integrally covered with an insulating material 12.

Further, the insulated wire 10 of the present invention
As shown in FIG. 6, a configuration in which the adhesive 14 is provided on one surface of the insulating material 12 may be employed. Then, when wiring is performed, the release paper 15 is peeled off, and the insulated wire 10 is attached and fixed to, for example, a wall surface or a floor surface with the adhesive material 14.

[0020]

Therefore, according to the present invention, at the time of wiring, the insulating material is peeled off to expose the screw insertion hole of the conductive material, and a screw is inserted into the screw insertion hole and screwed into the screw mounting position. The following advantages are obtained as compared with the method of crimping the terminal. No need for tools to crimp the terminals. High reliability because there is no crimping part. Check the mounting direction of the connection terminals to avoid the hassle of mounting. Therefore, workability can be improved as compared with the related art.

Also, since it is flat, it does not take up much space and can be mounted thin, for example, when wiring is performed along the board surface in the device.

According to the second aspect of the present invention, it is not necessary to crawl several electric wires when obtaining electrical conduction at a plurality of locations.

According to the third aspect of the present invention, since the adhesive is attached with an adhesive material, the wiring state can be integrated with a wall surface or a floor surface, etc., and can be finished finely. There is no risk of snagging.
