[0095] In the embodiment of the present application, the second protective tube 312 is configured to have a conical structure, wherein the two ends of the second protective tube 312 along the second direction are respectively a large end 3121 and a small end 3122, wherein the large end 3121 is connected to the small end 3112, so that the cable body 32 can be conveniently inserted from the large end 3121 and passed through the small end 3122, thereby facilitating the quick insertion of the cable body 32 into the interior of the second protective tube 312.

[0096] Optionally, along the first direction, the difference between the size of the small end 3112 and the size of the large end 3121 is not less than the diameter of the core wire.

[0097] exist Figure 4 In the figure, the big end 3111 and the small end 3112 of the first protective tube 311 are consistent in shape and size, and the big end 3121 and the small end 3122 of the second protective tube 312 are also consistent in shape and size, wherein the width of the first protective tube 311 is W1, and the width of the second protective tube 312 is W2, wherein the difference between the size of the small end 3112 and the size of the big end 3121 is the difference between W1 and W2, and the difference between the sizes of W1 and W2 is greater than or equal to the diameter of a core wire, so that the first core wire 321 can be easily led out.

[0098] In the embodiment of the present application, the cable assembly 30 includes multiple core wires arranged side by side along the first direction, and the difference between the size of the small end 3112 and the size of the large end 3121 along the first direction is not less than the diameter of the core wire. In this way, a core wire can be passed through a position where the small end 3112 and the large end 3121 of the first cable tube are offset, and can be led out from the inside of the first protective tube 311 to the outside, so as to be electrically connected to other components of the electrical equipment 200.

[0099] Optionally, along the first direction, the difference between the size of the small end 3112 and the size of the large end 3121 is W, the difference between the number of core wires in the first protective tube 311 and the number of core wires in the second protective tube 312 is N, W is greater than the sum of the diameters of the N core wires, and N is a positive integer greater than 1.

[0100] Continue to refer to Figure 4 As shown, when two or more core wires need to be led out at the same time, they can be led out from both sides of the second protective tube 312 along the width direction, or they can be led out from one side of the second protective tube 312 along the width direction. In order to facilitate the lead-out of N core wires, W is greater than the sum of the diameters of the N core wires, that is, the difference between W1 and W2 needs to be greater than or equal to the sum of the diameters of the N core wires, where N is a positive integer such as 2, 3 or 4.

[0101] In the embodiment of the present application, by making the difference W between the size of the small end 3112 and the size of the large end 3121 larger than the difference N between the number of core wires in the first protective tube 311 and the number of core wires in the second protective tube 312, wherein W is larger than the sum of the diameters of the N core wires, N core wires can be passed through the staggered positions of the small end 3112 and the large end 3121 of the first wiring tube at one time, so that the N core wires can be led out from the inside of the first protective tube 311 to the outside to be electrically connected to other components of the electrical equipment 200.

[0102] Alternatively, if Figure 6 As shown, the first protection tube 311 is provided with a first opening 3113 , and the first opening 3113 is provided on a side surface of the first protection tube 311 .

[0103] It should be noted that the two ends of the first opening 3113 are respectively connected to the two ends of the first protection tube 311 along the second direction, so that the structure of the first protection tube 311 with the first opening 3113 can be formed by a plate-like structure through a winding process.

[0113] Optionally, the number of protective tubes here is two, or the number of protective tubes can be set to three or four. In this case, the protective member 31 is composed of three sections of protective tubes with different widths or four sections of protective tubes with different widths, wherein the newly added protective tube can be connected to the large end 3111 of the first protective tube 311, or to the small end 3122 of the second protective tube 312, and corresponding changes can be made according to the width change of the cable body 32.

[0114] For example, the cable body 32 is a structure with three sections of different widths. In this case, the protective tube uses three sections of different widths to protect the three sections of the cable body 32 respectively, thereby protecting the cable body 32 of different widths.
