[0017] To enable those skilled in the art to better understand and implement this patent, the markings in the accompanying drawings are explained in detail below.
[0018] In the figure: 1—shell, 2—electrical unit, 11—body, 12—extension, 13—extension groove, 14—accommodating groove, 21—conductor, 22—insulating layer, 141—extension groove.
[0019] Implementation Example 1: Please see Figures 1 to 4 A power cable with a rectangular cross-section has a shell 1 and multiple electrical units 2. Each electrical unit 2 is composed of a conductor 21 and an insulation layer 22, with the insulation layer 22 covering the conductor 21. The shell 1 is composed of multiple bodies 11 and multiple extensions 12. The bodies 11 are identical and arranged in parallel. The extensions 12 connect adjacent bodies 11. Multiple receiving grooves 14 are distributed at intervals inside the bodies 11. The extensions 12 are distributed at intervals between adjacent bodies 11, and extension grooves 13 are formed between adjacent upper and lower extensions 12. The electrical units 2 are located in the receiving grooves 14 and extension grooves 13.
[0020] The power cable with a rectangular cross-section described above is characterized in that there are no electrical units 2 between adjacent extension bodies 12, and within the uppermost and lowermost extension grooves 13.
[0021] The power cable with a rectangular cross-section described above is characterized in that: each body 11 has multiple receiving grooves 14 and adjacent receiving grooves 14 do not contact each other.
[0022] The power cable with a rectangular cross-section described above is characterized in that: the shell 1 is an integral structure.
[0023] The power cable with a rectangular cross-section described above is characterized in that: the cross-section of the shell 1 is rectangular.
[0024] The power cable with a rectangular cross-section described above is characterized in that the material of the shell 1 is plastic.
[0025] The aforementioned power cable with a rectangular cross-section has three rows of body 11 and two rows of extensions 12.
[0026] Implementation Example 2: Please see Figure 5 and refer to Figures 1 to 4 A power cable with a rectangular cross-section, basically the same as in Implementation Example 1, except that it has four rows of body 11 and three rows of extensions 12.
[0027] Implementation Example 3: Please see Figure 6 and refer to Figures 1 to 5 A power cable with a rectangular cross-section, basically the same as in Implementation Example 1, except that it has five rows of body 11 and four rows of extensions 12.
[0028] Implementation Example 4: Please see Figure 7 and refer to Figures 1 to 6 A power cable with a rectangular cross-section is basically the same as the above-described embodiment, except that: the shell 1 is composed of a body 11 and multiple extensions 12. The extensions 12 protrude from the left edge of the body 11, and the width of the extensions 12 is the same. The extensions 12 are spaced apart on the left edge of the body 11, and an extension groove 141 is formed between adjacent extensions 12. The space above the uppermost extension 12 and the space below the lowermost extension 12 are extension slots 13. When forming the cable, multiple identical shells 1 are taken and arranged in parallel, with all extensions 12 facing the same direction. The extensions 12 of the later ones are tightly attached to the surface of the body 11 of the previous shell 1. The electrical unit 2 is placed in the receiving groove 14 and the extension slot 13. The extension 12 on the surface of the outermost body 11 is then cut off, forming a shell adhesive with a rectangular cross-section. In use, the extensions 12 are separated and the electrical unit 2 is removed, thus completing the separation.
