Description

[Detailed Description of the Invention] This invention relates to a low voltage divided conductor electric wire having a plurality of dividing lines at one end.

Traditionally, electricity was supplied to ordinary households as shown in Figure 1.
A supplementary line 3 is connected to the low-voltage main line 1 that is installed on the pillar via a connecting part 2 using a C-type connector, etc., and this supplementary line 3 is wired between touch fuses 4a, 4b, and 4c, and is further connected to a butt fuse. 4a..., each customer's roof is constructed by connecting a drop-in line 5 to every second or third house.

However, the butt fuses 4a were not good because they caused malfunctions, and leaded wire fuses were used instead.

That is, as shown in FIG. 2, branch wires 7a and 7b are branched and connected to the supplementary wire 3 by a branch portion 6, and wire fuses 9av9b are further connected to the branch wires 7a and 7b via connection portions 8av8b, respectively. Drop-in lines 11a and llb are connected via the connecting portions 10a and 10b.

This wiring method requires many connection points, that is, the connection part 2, both sides of the branch part 6, and both sides of the wire fuses 9a and 9b, making the wiring work complicated and time-consuming. There are disadvantages such as an increase in the number of locations where this occurs.

In addition, in the above-mentioned methods, supplementary wires of the same diameter are used even if the amount of electricity used by the consumer differs, so supplementary wires of the appropriate size according to each amount of electricity used are not used, which is wasteful. was there.

The purpose of this invention is to provide a split conductor wire that reduces the number of connection points, simplifies wiring work, and reduces raw material costs.

An embodiment of this invention will be described based on the accompanying drawings.

As shown in FIGS. 3 and 4, the compressed conductor 20 is made by twisting three wires 21a, 21b, 21c and wires 21d, 21e, 21f smaller in diameter than these wires, and compressing them. It is formed by molding cotton.

This compressed conductor 20 is collectively insulated by a collective insulation coating 22 .

Moreover, strands 21a and 21b. 21c and other strands 21d
, 21e, 21f are insulation coatings 23a, 23b, 23c, 23d, 23e, 2 individually starting from the terminal end of the collective insulation coating 22.
It is insulated by 3f.

Moreover, the bulk insulation coating 22 and the insulation coating 23 of the compressed conductor 20
a, 23 b, 23 C, 23 d, 23 e
, 23f is covered by a protective coating 24.

Since this divided conductor wire is made up of strands of two different sizes, it is used at branch points where the amount of power used can be divided into two for six consumer locations.

Further, the compressed conductor 20 is compression molded, and as shown in FIG. 4, has a circular cross section with no gaps between the wires.

As another example of compression molding, as shown in FIG. 5, the degree of compression during molding may be adjusted to leave some gaps between the strands.

In such compression molding, hardening and deformation of the strands due to processing are small, and therefore wiring connections are easy.

Note that the combination of wires may be appropriately composed of one wire or several wires of different diameters depending on the usage conditions, or the combinations may be organized, integrated, and standardized.

To use the split conductor wire, first connect the compressed conductor of the split conductor wire to the low voltage number 1 using a C-type connector, and then connect the wires 21a, 21b, etc. at the other end according to the expected power consumption. The lead-in wire 1 is individually connected to the electric wire fuses 9a, 9b, and further connected to the electric wire fuses 9a, 9b, and so on.
1a, 11b, . . . are connected.

Therefore, compared to the prior art, the connections on both sides of the branch portion 6 are omitted, and the number of connection points is reduced.

The split conductor electric wire of this invention has an integrated compressed conductor consisting of multiple strands divided into individual strands at one end, and can be used at branch points of electrical wiring to wire without branching and connecting. Branching can be performed.

Furthermore, since connections for branch connections are not required, the number of connection points is reduced, contributing to labor savings in wiring work and improved safety of electric wire facilities.

Furthermore, raw material costs can be reduced by using strands that match the power consumption, and since the strands are compression molded, defects such as floating strands and twists caused by strands of different diameters are eliminated. It has the following effects.
