FIG. 1 is a schematic diagram of a square insulated wire according to an embodiment of the present utility model;
fig. 2 is a schematic structural diagram of another embodiment of a square insulated wire according to the present utility model.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1, the square insulation wire disclosed by the utility model comprises a plurality of copper wire cores 10, a first ETFE material layer 11, a second ETFE material layer 12 and a third ETFE material layer 13.
The first ETFE material layer 11 has a square shape, wherein the first ETFE material layer 11 is wrapped around the plurality of copper wire cores 10.
Preferably, the plurality of copper wire cores 10 are arranged in parallel in a plurality of rows. It should be appreciated that the copper core 10 is bare copper.
Further, the area of the cross section of the plurality of copper wire cores 10 arranged in parallel in sequence is equal to the area of the cross section of the inner cavity of the first ETFE material layer 11.
The second ETFE material layer 12 has a square shape, wherein the second ETFE material layer 12 is wrapped around the first ETFE material layer 11.
The outer shape of the third ETFE material layer 13 is square, wherein the third ETFE material layer 13 is wrapped outside the second ETFE material layer 12.
In this embodiment, the inner cavities of the first ETFE material layer 11, the second ETFE material layer 12 and the third ETFE material layer 13 are all directional.
It should be understood that, since the shapes of the first ETFE material layer 11, the second ETFE material layer 12 and the third ETFE material layer 13 are square, the square insulation wire of the embodiment is not smooth, and the corners outside the square insulation wire have a clamping effect, so that the square insulation wire of the embodiment is not easy to be extruded by external force to generate lateral offset after being installed.
Further, since the inner cavities of the first ETFE material layer 11, the second ETFE material layer 12 and the third ETFE material layer 13 are all in a direction, the plurality of copper wire cores 10 accommodated in the first ETFE material layer 11 are not easy to be extruded by external force to generate lateral offset.
Preferably, the thickness of the first ETFE material layer 11, the second ETFE material layer 12 and the third ETFE material layer 13 ranges from 0.1 to 2 micrometers.
In the present embodiment, the thicknesses of the first ETFE material layer 11, the second ETFE material layer 12, and the third ETFE material layer 13 are all the same.
Of course, in other embodiments, the thicknesses of the first ETFE material layer 11, the second ETFE material layer 12, and the third ETFE material layer 13 are all different.
