[0028] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0029] This application provides a cable protection device, such as... Figures 1 to 8 As shown, the cable protection device includes a main body 100 and a first limiting block 200. The main body 100 is provided with a through hole 101 for the cable 10 to pass through and an installation port 102 communicating with the through hole 101. The two side walls opposite to the installation port 102 are provided with first limiting blocks 200, and a through gap 201 is formed between the two first limiting blocks 200. The width of the through gap 201 is smaller than the diameter of the through hole. The edge side 310 of the main body 100 is provided with a slot 103 for holding the mounting plate 20.

[0030] The cable protection device provided in this application embodiment has an installation port 102 on the main body 100 that communicates with the through hole 101. A cable passage gap 201 is formed between the first limiting blocks 200 on the two side walls opposite to the installation port 102. The width of the cable passage gap 201 is smaller than the diameter of the through hole. A slot 103 for holding the cable 10 with the mounting plate 20 is provided on the edge side 310 of the main body 100. Therefore, during the cable 10 wiring process, the cable protection device only needs to be held on the mounting plate 20 by the slot 103, and the cable 10 is inserted into the through hole 101 through the cable passage gap 201, making the cable passage operation of the cable protection device simple and convenient. The first limiting block 200 can prevent the cable 10 from coming loose from the through hole 101.

[0031] Optional, such as Figure 1 As shown, the first limiting block 200 has a first inclined surface 210 on the side opposite to the through hole. The first inclined surface 210 is used to guide the cable 10 into the cable passage gap 201. By setting the first inclined surface 210 to guide the cable 10, it is easier for the cable 10 to move from the mounting port 102 along the first inclined surface 210 to the cable passage gap 201, and then be inserted into the through hole 101 through the cable passage gap 201, thereby reducing the difficulty of the cable passage operation. Specifically, the cable 10 that needs to be wired passes through the mounting port 102, and under the guidance of the first inclined surface 210, it is inserted into the through hole through the cable passage gap 201.

[0032] In some embodiments of this application, such as Figures 1-3 As shown, the main body 100 includes a first protective layer 110, a second protective layer 120 and a third protective layer 130 stacked in sequence. The wire through hole 101 and the mounting port 102 both penetrate the first protective layer 110, the second protective layer 120 and the third protective layer 130. The upper surface of the first protective layer 110, the side surface 310 of the second protective layer 120 and the lower surface of the third protective layer 130 form a slot 103.

[0033] Optionally, the first protective layer 110, the second protective layer 120, and the third protective layer 130 each have a sub-through hole 104 and a sub-opening 105 communicating with the sub-through hole 104, and each of the two sidewalls opposite to the sub-opening 105 is provided with a limiting part 202, and a sub-gap 203 is formed between the two limiting parts 202; the sub-through holes 104 of the first protective layer 110, the second protective layer 120, and the third protective layer 130 are connected to form a wire-passing through hole 101, the sub-openings 105 of the three are connected to form an installation port 102, the limiting parts 202 of the three are stacked to form a first limiting block 200, and the sub-gap 203 of the three are connected to form a wire-passing gap 201.

[0034] Specifically, since the first protective layer 110, the second protective layer 120, and the third protective layer 130 are stacked sequentially, the sub-through holes 104 of the first protective layer 110, the second protective layer 120, and the third protective layer 130 are connected in the stacking direction to form a wire through hole 101, the sub-openings 105 of the first protective layer 110, the second protective layer 120, and the third protective layer 130 are connected in the stacking direction to form an installation port 102, the limiting portions 202 of the first protective layer 110, the second protective layer 120, and the third protective layer 130 are stacked to form a first limiting block 200, and the sub-gap 203 of the first protective layer 110, the second protective layer 120, and the third protective layer 130 are connected in the stacking direction to form a wire through gap 201.

[0035] In some embodiments of this application, such as Figures 4-6As shown, the cable protection device also includes a second limiting block 300, which is disposed at one end of the through hole 101 in the axial direction. The second limiting block 300 has a through notch 301 for the cable 10 to pass through, and the width of the through notch 301 is smaller than the diameter of the through hole 101. By providing the second limiting block 300 at one end of the through hole 101 in the axial direction, the second limiting block 300 can change the torque path, making it less likely for the cable protection device to fall off the mounting plate 20.

[0036] Specifically, in combination Figure 6 As shown, cable 10 includes a first end 11 and a second end 12. The first end 11 is installed on the control board, and the second end 12 is connected to the working device. A in the figure is the contact point between the edge of the mounting plate 20 and the cable protection device. Since the first end 11 of cable 10 needs to be installed first, only the second end 12 of cable 10 will generate tension during installation. When the cable protection device is subjected to the tension of cable 10, the resultant force direction intersects with the mounting plate 20 at point B, which is far away from the edge of the mounting plate 20. Compared with the contact point A between the edge of the mounting plate 20 and the cable protection device, the cable protection device can be effectively prevented from falling off the mounting plate 20, thereby protecting the cable 10.

[0037] Optionally, the side of the second limiting block 300 facing the main body 100 is provided with a second inclined surface 302 on both sides of the wire passage notch 301. By setting the second inclined surface 302, the surface area of ​​the two opposite side walls of the wire passage notch 301 can be reduced. When the cable 10 passes through the wire passage notch 301 of the second limiting block 300, the smaller contact surface can reduce friction and facilitate wiring.

[0038] Optionally, a third inclined surface 303 is provided at the opening of the cable passage notch 301. The third inclined surface 303 is used to guide the cable 10 into the cable passage notch 301. By providing the third inclined surface 303 to guide the cable 10, it is easier for the cable 10 to be inserted into the cable passage notch 301 from the opening of the cable passage notch 301 along the third inclined surface 303, thereby reducing the difficulty of the cable passage operation.

[0039] In some embodiments of this application, such as Figure 7 and Figure 8 As shown, a reinforcing block 400 is provided on the side 310 of the second limiting block 300, and the reinforcing block 400 is connected to the main body 100. By providing the reinforcing block 400, the second limiting block can maintain its relative position on the main body 100 when subjected to the stress of the cable 10.

[0040] Specifically, the side 310 of the second limiting block 300 may include a first side 311, a second side 312 and a third side 313. The first side 311 and the third side 313 are located on opposite sides of the wire passage notch 301, and the second side 312 is connected between the first side 311 and the third side 313. Reinforcing blocks 400 may be provided on the first side 311, the second side 312 and the third side 313.

[0041] Optionally, the reinforcing block 400 is provided with a fourth inclined surface 401, which connects the side surface 310 of the second limiting block 300 with the side of the main body 100 facing the second limiting block 300. By providing the fourth inclined surface 401 on the reinforcing block 400, the relative position of the second line limiting block on the main body 100 can be maintained more effectively when it is subjected to the stress of the cable 10.

[0042] Optionally, the cable protection device is a component made of rubber or silicone material. That is, the cable protection device can be made of rubber or silicone material, which will not damage the outer sheath of the cable 10 and helps to protect the cable 10.

[0043] It is understood that the number of through holes 101 can be one or more to allow multiple cables 10 to pass through; the number of mounting ports 102 is the same as the number of through holes 101, and the number of second limiting blocks 300 is also the same as the number of through holes 101. For example, as... Figure 1 and Figure 4 In the embodiment shown, there are two through holes 101, and correspondingly, there are also two mounting ports 102 and two limiting blocks 300. The two mounting ports 102 are connected to the two through holes 101 in a one-to-one correspondence, and the two limiting blocks 300 are assembled to the two through holes 101 in a one-to-one correspondence.
