Description

[Detailed Description of the Invention] This invention connects 1! This invention relates to a wire device that reduces gLm resistance.

Conventional electric wires have a circular cross-sectional shape, so when the electric wires are connected using a flat connector, the connection portion is a linear connection. In addition, in the case of the thickest single wire that cuts through the coating, S
There were some cases where the wires could be cut, and in the case of thin multiple wires, the outer wires could break.

In this invention, when connecting 1f51 with a connecting tool having a flat surface, ? The purpose is to reduce the electrical resistance, and also to prevent the wire from being cut or cut when the sheath is removed.

To explain this invention based on the drawings, @1.2111
! As shown in II, the cross-sectional shape of the wire is made to have a pair of parallel lines, and the cross-sectional shape of the wire coating is made to have two pairs of parallel lines that are perpendicular to each other, and the cross-sectional shape of the wire is made to have two pairs of parallel lines that are parallel to each other and perpendicular to the surface side. This is an electric wire device that has a cut groove in the middle of a pair of parallel surfaces.

Therefore, by changing the cross-sectional shape of the wire to form a pair of parallel lines, parallel surfaces can be created in the wire. Due to the presence of parallel surfaces, if the wire is connected with a connecting tool with a flat surface,
The electric resistance can be lowered than the linear connection electric resistance of conventional electric wires whose cross-sectional shape is circular.

Also, electricity &! The cross-sectional shape of the sheathing has two pairs of parallel lines that are perpendicular to each other, and a cut groove is cut in the middle of the pair of parallel faces of the sheath that are perpendicular to the parallel side of the wire. By cutting the groove a little, the coating can be split in two. Because it can be torn, there will be no cuts or cuts to anything other than the tip of the wire.

Furthermore, when the wire is used and the sheathing is to be separated from the wire, the sheathing can be torn, so the sheathing and the wire can be easily separated.

In addition, when connecting with screws, with conventional electric wires, a rotational force is applied to the wire when the screw is screwed in, and when a tension force is applied to the wire after the connection is completed, rotational force is applied to the screw. In order to improve this, it was necessary to attach a hole punching tool to the S wire, but in this invention, the wire has a pair of parallel surfaces, so it is possible to directly punch a hole in the wire.
In addition to eliminating the need for a hole puncher, as shown in FIG. 3, by utilizing the parallel surfaces of the electric wire of the present invention, the electric wires of the τα line can be overlapped and connected.

In addition, this invention can reduce the connection electrical resistance with respect to the length of the connection part of conventional electric wires, so that the connection pressure can be lower than that of conventional electric wires. Due to the fact that there are grooves in the coating,
If you make cuts perpendicular to the wire at certain intervals on one side of the wire, close to the wire, you can tear off only the insulation between the cuts, so you can tear out the flat wire from any point on the wire. coming out. Using the above, we can arrange these electric wires in parallel on a plane at a certain interval, as shown in m41g, and if we use a material that can be used with wood screws as the plane material (3), we can wire these parallel electric wires. As long as you have a device (4) that can make contact with the
Because electricity can be supplied from any position on the flat tm material B (3) to which these parallel electric wires are attached, conventionally, when changing the location of an electricity extraction device from a wall or ceiling, it was not necessary to tear down the wall or ceiling. Otherwise, the position could not be changed, but if the flat material (3) with parallel wires is applied inside the wall or ceiling, the position can be easily changed between the materials, and 1. ! When installing the air extraction device, the pressure direction and the 1% connection pressure direction are the same, so the installation screws for the electrical extraction device and the electrical wiring installation screws can be made the same.
