The isolator can rotate with the rotating disk around the central axis of the rotating base to change the shape of the sections.

[0007] In some possible embodiments, the rotating seat protrudes from the center of one end of the locking member, and the rotating seat includes:

[0008] The main body contains a rotating cavity.

[0017] The first limiting part is used to restrict the rotating part from disengaging from the rotating cavity along the width direction of the isolation member;

[0018] The second limiting part is used to restrict the rotating part from disengaging from the rotating cavity along the length direction of the isolation member.

[0019] In some possible embodiments, the isolator is further provided with a limiting arm, which extends obliquely downward from the lower end of the isolator along the width direction of the isolator to near the rotating part. The distance between the free end of the limiting arm and the end face of the locking part is less than the height of the first limiting part protruding from the end face of the locking part. The limiting arm can abut against the outer side of the first limiting part to prevent the rotating part from disengaging from the rotating cavity through the notch.

[0020] In some possible embodiments, the isolator is further provided with a positioning arm that extends from the lower end of the isolator along the width direction of the isolator. The free end of the positioning arm is provided with a positioning part that can elastically press against the end face of the clip to prevent the isolator from rotating relative to the clip.

Detailed Implementation

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] Reference Figures 1 to 7The diagram shows a rotatable and adjustable isolation structure, comprising a clip 10 and an isolation member 20. The end face of the clip 10 is provided with a rotating seat 11, and the lower end of the isolation member 20 is provided with a rotating disk 21. The rotating disk 21 is detachably installed in the rotating seat 11 so that the isolation member 20 is installed at the rear end of the clip 10. The isolation member 20 divides the rear end area of ​​the clip 10 into different sections 12. Different cables can be correspondingly accommodated in different sections 12. That is, the isolation member 20 can physically isolate the cables at the rear end of the clip 10, avoiding cross-stacking between different cables. The rotating disk 21 can also rotate forward and backward around the central axis of the rotating seat 11 to change the shape of the section 12, thereby adapting to uneven cable routing. That is, when the cables in a certain section 12 are piled up in a certain area or direction, the isolation member 20 rotates relative to the clip 10 to increase the area of ​​the piled-up cables in that section 12, thereby providing sufficient space for cable arrangement.

[0049] In some possible embodiments, refer to Figures 1 to 4 as well as Figure 11 and 12 As shown, the rotating base 11 protrudes from the center of the end face of the clamping member 10. The rotating base 11 also includes a body 111 and a notch 113 formed on one side of the body 111. A rotating cavity 112 is formed inside the body 111 to accommodate the rotating disk 21. The body 111 can be integrally formed with the clamping member 10, or it can be fixedly installed on the clamping member 10 by bonding or ultrasonic welding. The rotating disk 21 is disposed at the lower end of the isolation member 20. The rotating disk 21 includes a rotating part 211. The connecting rod 212 is set at the lower end of the isolator 20. The specific rotating part 211 can be integrally formed with the isolator 20 and fixed to the isolator 20 by bonding or ultrasonic welding. During assembly, the rotating part 211 can move from the notch 113 to enter and be accommodated in the rotating cavity 112. The operator can drive the isolator 20 to rotate around the central axis of the rotating cavity 112 with the rotating part 211, thereby adjusting the shape of the interval 12 to accommodate cables piled up in a certain area or along a certain direction in the interval 12.

[0050] In some possible embodiments, refer to Figure 10 As shown, the rotating part 211 is cylindrical, spherical, conical, or elliptical, and the rotating cavity 112 is also adapted to be shaped to accommodate the rotating part 211.

[0051] In some possible embodiments, refer to Figure 11 and Figure 12As shown, the main body 111 includes a first limiting part 1111 and a second limiting part 1112. The first limiting part 1111 is annular, and the second limiting part 1112 is disposed at the upper end of the first limiting part 1111, so that the area enclosed by the first limiting part 1111, the second limiting part 1112 and the end face of the locking member 10 forms a rotating cavity 112. It should be understood that the second limiting part 1112 should also have a guide channel to accommodate the connecting rod 212, so as to ensure that the isolating member 20 can move with the connecting rod 212. The rotating part 211 is inserted into the rotating cavity 112 through the notch 113. At this time, the isolating member 20 should be located above the rotating seat 11 to divide the end face of the clamp 10 into different sections 12. After the rotating part 211 is inserted into the rotating cavity 112, the first limiting part 1111 can restrict the rotating part 211 from disengaging from the rotating cavity 112 along the width direction of the isolating member 20, and the second limiting part 1112 can restrict the rotating part 211 from disengaging from the rotating cavity 112 along the height direction of the isolating member 20.

[0052] In some possible embodiments, refer to Figures 1 to 4 as well as Figure 10 As shown, to prevent the rotating part 211 from detaching from the rotating cavity 112 at the notch 113 after assembly, a limiting arm 22 is also provided on the isolation member 20. The limiting arm 22 extends obliquely downward from the lower end of the isolation member 20 along the width direction of the isolation member 20 to near the rotating part 211. The distance between the free end of the limiting arm 22 and the end face of the locking member 10 is less than the height of the first limiting part 1111 protruding from the end face of the locking member 10. During assembly, the limiting arm 22 moves with the isolation member 20 before the rotating part 211. The limiting arm 22 moves into the rotating cavity 112 and abuts against the inner side of the first limiting part 1111. The limiting arm 22 continues to move with the isolating member 20 and moves past the first limiting part 1111 until the free end of the limiting arm 22 is located outside the first limiting part 1111. When the rotating part 211 disengages from the rotating cavity 112 at the notch 113, the free end of the limiting arm 22 will abut against the outer side of the first limiting part 1111, thereby preventing the rotating part 211 from detaching from the rotating cavity 112.

[0053] In some possible embodiments, refer to Figures 1 to 4 as well as Figure 10As shown, the isolator 20 is also provided with a positioning arm 23. The positioning arm 23 extends from the lower end of the isolator 20 along the width direction of the isolator 20. The free end of the positioning arm 23 is provided with a positioning part 231. After assembly, the positioning part 231 can elastically press against the end face of the clamp 10. That is, the friction between the positioning part 231 and the end face of the clamp 10 is used to suppress the tendency of the isolator 20 to rotate relative to the clamp 10, so that the isolator 20 will only rotate when subjected to an external force higher than the friction force. Furthermore, the end face of the clamp 10 is also provided with a positioning groove 13 that cooperates with the positioning part 231. When the isolator 20 rotates relative to the clamp 10 until the positioning part 231 is engaged in the positioning groove 13, the resistance of the isolator 20 to rotate relative to the clamp 10 is further enhanced, thereby fixing the isolator 20 at a pre-designed specific angle and preventing the isolator 20 from rotating relative to the clamp 10 and deviating from the pre-designed angle position after assembly due to a little external force.

[0054] In some possible embodiments, refer to Figure 1 , 3 As shown in Figure 10, the isolator 20 is also provided with several easy-tear lines 25. The easy-tear lines 25 can be arranged along the width direction of the isolator 20 and are distributed at intervals along the height direction of the isolator 20 on the surface of the isolator 20. When in use, a part of the isolator 20 can be folded off along the easy-tear lines 25. The purpose is that the height of the isolator 20 can be adjusted according to the depth of the matching junction box 30 or the back cover.

[0055] In some possible embodiments, refer to Figures 1 to 4 as well as Figure 10 As shown, the isolator 20 is also provided with a third limiting part 24, which is disposed on at least one side of the connecting rod 212. The third limiting part 24 can enter the guide channel as the rotating seat 11 enters the rotating cavity 112, and cooperates with the side wall of the guide channel to limit the rotation stroke of the isolator 20. In some embodiments, the third limiting part 24 can extend along the width direction of the isolator 20 on opposite sides of the connecting rod 212 to enhance the structural strength of the isolator 20 and the rotating part 211.

[0056] It should be noted that, referring to Figure 5In some embodiments, the shape of the card 10 may be rectangular. Since the length and width of the rectangle are not consistent, when the isolation member 20, which is slightly wider than the width of the card 10, is rotated to the length direction of the card 10, the space of the junction box 30 fitted on the card 10 cannot be divided into two basically independent sections because the width of the isolation member 20 is shorter than the length of the card 10. This may still cause contact between the input cable and the output cable. When the isolation member 20, which is slightly wider than the length of the card 10, is rotated to the width direction of the card 10, the card 10 cannot be installed into the junction box 30 with a matching shape because the width of the isolation member 20 is much longer than the width of the card 10. Therefore, for rectangular card 10, it is usually necessary to use two sizes of isolation members 20. The third limiting part 24 needs to cooperate with the guide channel to prevent the isolation member 20, which is slightly wider than the width of the card 10, from rotating to the length direction of the card 10, or to prevent the isolation member 20, which is slightly wider than the length of the card 10, from rotating to the width direction of the card 10. Reference Figure 5 As shown, when the limiting arm 22 is not on the side opposite to the notch 113, the limiting arm 22 cannot prevent the rotating part 211 from disengaging from the rotating cavity 112. By limiting the rotation stroke of the isolation member 20, the limiting arm 22 can also be prevented from rotating to the side not opposite to the notch 113, thus preventing the rotating part 211 from disengaging from the rotating cavity 112.

[0057] Specifically, in this embodiment, referring to Figure 5 A notch 114 is formed on the side of the second limiting part 1112 opposite to the notch 113. The notch 114 and the notch 113 are respectively provided on both sides of the second limiting part 1112 along the width direction of the locking member 10, and the notch 114 and the notch 113 are connected to form a transverse guide channel. The third limiting part 24 can only reciprocate within the notch 114 with the rotating part 211. For the separator 20 applied in the width direction of the locking member 10, refer to... Figure 10 The third limiting part 24 extends along the width direction of the isolator 20 on both opposite sides of the connecting rod 212, thereby preventing the isolator 20 from rotating in the length direction of the clamp 20; for the isolator 20 applied in the length direction of the clamp 10, refer to Figure 15 The limiting arm 22 is arranged on both sides of the connecting rod 212 in a direction perpendicular to the surface of the isolation member 20. The third limiting part 24 is arranged at the connection between the limiting arm 22 and the main body of the isolation member 20, thereby preventing the isolation member 20 from rotating to the width direction of the clamp 20. The third limiting part 24 can also enhance the strength of the connection structure between the limiting arm 22 and the isolation member 20.

[0058] This utility model also provides an electrical device, as described above. Figure 8 , Figure 9 and Figure 16As shown, it includes a rotatable and adjustable isolation structure as described in the above embodiment, and also includes a junction box 30. The card 10 can be accommodated in the junction box 30, and a cavity for accommodating cables is formed between the rear end face of the card 10 and the bottom of the junction box 30. The rear end face of the card 10 is also provided with at least two terminals 14, which are located in different intervals 12.

[0059] The electrical device can be a dimming controller, with one terminal 14 connected to an input cable and the other terminal 14 connected to an output cable. An isolation structure separates the input and output cables to prevent them from overlapping and causing safety hazards. (Refer to...) Figure 13 and Figure 14 In practice, dimming controllers are often installed on walls, with input and output cables typically located on the top and bottom sides of the controller, respectively. The specific location of the input cable is influenced by the installer's habits; it might be positioned to the upper left or upper right of the dimming power supply. The two terminals 14 of the dimming controller are usually located diagonally opposite each other on the card 10. In this case, it is advisable to install the isolator 20 along the length of the card 10. When the input cable is located to the upper left of the dimming controller, the isolator 20 can be installed along the positive direction of the card 10's length, i.e., vertically, so that the isolator 20 can be positioned according to... Figure 13 The input and output cables are isolated as shown. When the input cable is located at the upper right of the dimming controller, the isolator 20 can be rotated clockwise by a certain angle so that it is positioned along the diagonal from the upper right to the lower left of the card 10, allowing the isolator 20 to be aligned accordingly. Figure 14 The input and output cables are isolated as shown. This electrical device allows for flexible selection of the appropriate isolator 20 based on the actual location of the input and output cables. The isolator 20 can be rotated to adjust the direction of the cable-accommodating section 12, ensuring effective isolation of the input and output cables regardless of their location, thus facilitating the installation and wiring of the electrical device.

[0060] Reference Figure 16 In some embodiments, the junction box 30 has a plurality of knock-out holes 31 on its surface. When in use, the cover plate on the corresponding knock-out hole 31 can be knocked off according to the actual position of the input cable and the output cable to form a through hole for the cable to pass through.
