[0031] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] In the description of the present invention, it should be understood that taking Figure 3 the position of the lifting plate 4 relative to the cylinder 7 as up, and vice versa as down, the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "up", "down", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention.

[0033] Referring to Figures 1-9 , a cable protection device for electrical cabinet wiring provided by an embodiment of the present invention includes a plurality of terminals 2 for plugging into the cabinet 1, and a connection part 3 is provided between each of the terminals 2 and each cable; a support mechanism is further included, the length of the support mechanism is greater than the distance between adjacent two connection parts 3, the support mechanism has a first position for abutting against the connection part 3 for support and a second position away from the connection part 3; a first power component for driving the support mechanism to switch between the first position and the second position is further included.

[0034] Specifically, an electrical cabinet is usually used to store electrical equipment and control equipment to protect them from the external environment. The cable is in the shape of a wire, and the terminal 2 is the connector at both ends of the cable. An interface adapted to the terminal 2 is provided on the cabinet body 1. Through the insertion of the terminal 2 into the interface, signal transmission is achieved. The connecting part 3 is arranged between the cable and the terminal 2, and the connecting part 3 is preferably made of hard plastic material. To prevent damage to the terminal 2 and the connecting part 3, protective shells are usually sleeved one by one at the connection position between the terminal 2 and the connecting part 3 to achieve the purpose of protection, thereby ensuring the normal connection of the equipment. This is the prior art and will not be elaborated. One of the core innovation points of the embodiment of the present invention is that a support mechanism is provided below the connecting part 3. The support mechanism can be in the shape of a long plate and is horizontally arranged below the connecting part 3. The first power component is an existing reciprocating drive component such as an electric push rod 27. The effect of such a setting is that when installing the terminal 2, the support mechanism is controlled by the first power component to be in the second position, so that the support mechanism is far away from the terminal 2, thereby facilitating the installation of the terminal 2. After the terminal 2 is installed, the support mechanism is controlled by the first power component to switch from the second position to the first position. Since the length of the support mechanism is greater than the distance between adjacent two connecting parts 3, the support mechanism can simultaneously abut against multiple (at least two) connecting parts 3 to achieve the support effect, thereby protecting multiple connecting parts 3 and the terminal 2, and the operation is convenient.

[0035] Preferably, the support mechanism includes a lifting plate 4 slidably arranged on the cabinet body 1. A plurality of vertical rods 5 are arranged on the lifting plate 4, and the plurality of connecting parts 3 are respectively located on the moving strokes of the plurality of vertical rods 5. Specifically, a vertical groove 6 is opened on the outer side wall of the cabinet body 1, and the lifting plate 4 can slide vertically along the vertical groove 6. The plurality of vertical rods 5 are all arranged on the upper surface of the lifting plate 4. By the vertical movement of the lifting plate 4, the vertical rods 5 can be driven to abut against and move away from the connecting part 3, thereby facilitating the switching of the support mechanism between the first position and the second position.

[0036] Preferably, the first power component includes a cylinder 7. The cylinder 7 is fixedly connected to the cabinet body 1, and the output end of the cylinder 7 is fixedly connected to the lifting plate 4. By controlling the extension or contraction of the output end of the cylinder 7, the power required for the support mechanism to switch between the first position and the second position can be provided.

[0037] As another embodiment of the present invention, a self-adjusting mechanism for adaptively supporting terminals 2 of different heights is provided between the vertical rods 5 and the cabinet body 1. Specifically, the plurality of vertical rods 5 are all slidably arranged on the lifting plate 4. The self-adjusting mechanism can be a plurality of reciprocating drive components such as a plurality of electric push rods 27. The output ends of the plurality of electric push rods 27 are independently connected to the plurality of vertical rods 5 respectively, so as to realize the independent control of the plurality of vertical rods 5, thereby facilitating the adaptation to terminals 2 of different heights.

[0038] As another embodiment of the present invention, the self-adjusting mechanism includes a top plate 8, a sliding seat 9 is fixedly connected to the cabinet body 1, the top plate 8 is slidably arranged on the sliding seat 9, a through hole 10 is opened on the top plate 8, a plug pin 11 is slidably arranged in the through hole 10, a jack 12 adapted to the size of the plug pin 11 is opened on the vertical rod 5, a plurality of positioning holes 13 adapted to the size of the plug pin 11 are opened on the sliding seat 9, and the plug pin 11 has a first state of being inserted into the jack 12 and a second state of being inserted into one of the positioning holes 13; further includes a second power assembly for driving the plug pin 11 to switch between the first state and the second state. Specifically, in this embodiment, the vertical rod 5 is fixedly connected to the lifting plate 4, and the connecting portion 3 is located on the moving stroke of the top plate 8. A slide rail 14 is opened on the sliding seat 9, a sliding connection portion 15 is arranged on the top plate 8, the sliding connection portion 15 is slidably connected with the slide rail 14, the through hole 10 is opened inside the top plate 8 and is horizontally arranged, the plug pin 11 is a cylindrical rod structure and is coaxially arranged with the through hole 10, the positioning holes 13 are uniformly arranged vertically on the side wall of the sliding seat 9, and the second power assembly is an existing reciprocating driving assembly such as an electric push rod 27. The function of such a setting is that when the support mechanism (referring to the top plate 8 in this embodiment) is in the second position, the plug pin 11 is in the first state, so that the plug pin 11 is inserted into the jack 12. When the support mechanism switches from the second position to the first position, the cylinder 7 is started, the output end of the cylinder 7 extends, thereby driving the lifting plate 4 and the vertical rod 5 to move vertically upward, and under the action of the plug pin 11 being inserted into the jack 12, the top plate 8 will be driven to move upward synchronously. When one of the top plates 8 abuts against the connecting portion 3 at the lowest position, then the plug pin 11 corresponding to the top plate 8 is controlled by the second power assembly to switch from the first state to the second state, so that the plug pin 11 is connected to one of the positioning holes 13, so that the top plate 8 and the sliding seat 9 are connected as a whole (that is, the top plate 8 will not continue to move upward during the subsequent upward movement of the vertical rod 5), so as to fix the top plate 8 in the first position to achieve the support effect, and then the remaining top plates 8 are controlled to continue to move upward by the cylinder 7. When another top plate 8 abuts against the connecting portion 3 at the second lowest position, the above operation will be repeated, and so on, the self-adaptive adjustment of the heights of multiple top plates 8 can be realized. When the vertical rod 5 moves vertically downward, when the jack 12 descends to be coaxial with the plug pin 11, the plug pin 11 is controlled by the second power assembly to switch from the second state to the first state, so that the top plate 8 is connected to the vertical rod 5, and the top plate 8 is driven to automatically reset when the vertical rod 5 descends, for the next support.

[0039] Preferably, the positioning hole 13 is constructed with an open end, that is, the entrance area of the positioning hole 13 is larger than its internal area, so as to facilitate the insertion of the plug pin 11 into the positioning hole 13.

[0040] As another embodiment of the present invention, a support rod 16 is elastically arranged on the top plate 8. A lifting groove 17 is formed at the top end of the top plate 8. The support rod 16 is slidably connected to the lifting groove 17. The elastic arrangement here means that a first spring 18 is arranged between the bottom end of the support rod 16 and the lifting groove 17. And in this embodiment, the connecting part 3 is located on the moving stroke of the support rod 16. The function of such an arrangement is that during the process of the top plate 8 driving the support rod 16 to move upward, the support rod 16 will be in contact with the connecting part 3 to achieve the supporting effect, and the first spring 18 can buffer the acting force between the support rod 16 and the connecting part 3, thereby avoiding damage to the connecting part 3.

[0041] As still another embodiment of the present invention, the second power assembly includes an elastic telescopic rod 19. An activity cavity 20 is formed inside the top plate 8. A first rotating seat 21 is arranged on the inner wall of the activity cavity 20. A second rotating seat 22 is arranged on the plug pin 11. The two ends of the elastic telescopic rod 19 are respectively rotatably connected to the first rotating seat 21 and the second rotating seat 22. A transmission member for driving the second rotating seat 22 to move horizontally is arranged between the support rod 16 and the second rotating seat 22. The transmission member includes a transmission rod 23. A contact rod 24 is rotatably arranged on the inner wall of the activity cavity 20. One end of the transmission rod 23 is fixedly connected to the support rod 16, and the other end of the transmission rod 23 is in contact with the contact rod 24. The second rotating seat 22 is located on the rotating stroke of the contact rod 24. Specifically, the elastic telescopic rod 19 can extend or contract, and has the ability of automatic restoration through elastic components such as springs, and the elastic components are always in a compressed state. When the plug pin 11 is in the first state, the elastic telescopic rod 19 is inclined to the left. When the plug pin 11 is in the second state, the elastic telescopic rod 19 is inclined to the right. In this embodiment, the plug pin 11 includes a first section 1101 and a second section 1102 that are slidably connected to each other, and the second rotating seat 22 is fixedly connected to the first section 1101. A second spring 25 is arranged between the first section 1101 and the second section 1102. When the plug pin 11 is in the first state and the second state, the second spring 25 is in a natural state. Rotating shafts are arranged on both the first rotating seat 21 and the second rotating seat 22. Rotating holes are arranged at both ends of the elastic telescopic rod 19. The two rotating holes are respectively rotatably connected to the two rotating shafts. The transmission rod 23 is fixedly connected to the lower surface of the support rod 16 and penetrates into the activity cavity 20. A horizontal shaft 26 is arranged in the activity cavity 20. The contact rod 24 can rotate vertically around the horizontal shaft 26. For example Figure 8As shown, the abutting rod 24 is approximately in an "S" shape. A horizontal portion 2401 is provided at its top end, and an abutting portion 2402 is provided at its bottom end. The bottom end of the transmission rod 23 abuts against the horizontal portion 2401. The second rotating seat 22 is located on the movement stroke of the abutting portion 2402. The horizontal shaft 26 is provided at the first inflection point position at the top of the abutting rod 24, and a torsion spring (not shown in the figure) is provided between the abutting rod 24 and the horizontal shaft 26. The elastic force of the torsion spring causes the abutting rod 24 to have a tendency to rotate counterclockwise. Specifically, when the top end of the support rod 16 abuts against the connecting portion 3, it will force the support rod 16 to move downward and compress the first spring 18. The support rod 16 will synchronously drive the transmission rod 23 to move vertically downward, thereby driving the bottom end of the transmission rod 23 to abut against the horizontal portion 2401 of the abutting rod 24, so that the abutting rod 24 rotates clockwise around the horizontal shaft 26, and the abutting portion 2402 of the abutting rod 24 abuts against the side wall of the second rotating seat 22, thereby pushing the second rotating seat 22 to move horizontally and driving the elastic telescopic rod 19 to rotate clockwise around the first rotating seat 21. Since the distance between the first rotating seat 21 and the first rotating seat 21 first shortens and then increases during the rotation process, that is, when the elastic telescopic rod 19 is in a vertical state, the elastic telescopic rod 19 is in the shortest state, and at this time, the elastic component inside the elastic telescopic rod 19 is compressed to the limit value. After the elastic telescopic rod 19 rotates past the vertical state, the elastic force of the elastic component inside it is instantly released, thereby driving the elastic telescopic rod 19 to extend. During the extension of the elastic telescopic rod 19, the latch 11 will be instantly inserted into the positioning hole 13 to realize the passive switching of the latch 11 from the first state to the second state.

[0042] Further, the second power assembly further includes a push rod 27. The push rod 27 is elastically arranged inside the sliding seat 9. A plurality of pushing portions 28 are arranged on the push rod 27. The plurality of pushing portions 28 are arranged in one-to-one correspondence with the plurality of positioning holes 13. A first abutting block 29 is arranged on the push rod 27, and a second abutting block 30 is arranged on the lifting plate 4. The first abutting block 29 is located on the movement stroke of the second abutting block 30. Specifically, an avoidance groove 31 is formed inside the sliding seat 9, and the push rod 27 is slidably arranged in the avoidance groove 31. Here, the elastic arrangement means that a third spring 32 is arranged between the push rod 27 and the avoidance groove 31. The elastic force of the third spring 32 has a tendency to make the push rod 27 move away from the positioning hole 13. The plurality of pushing portions 28 are evenly arranged on the push rod 27 and penetrate into the positioning hole 13. A rectangular hole 33 is formed in the lifting plate 4. The second abutting block 30 is arranged on the lower surface of the lifting plate 4. The first abutting block 29 is connected to the bottom end of the push rod 27 through a connecting rod, and the first abutting block 29 penetrates through the rectangular hole 33 and is located below the second abutting block 30. Wedge-shaped surfaces are arranged on both the first abutting block 29 and the second abutting block 30. The function of such an arrangement is that when the air cylinder 7 drives the lifting plate 4 to move vertically downward, since the bolt 11 is in the second state at this time, the top plate 8 will not move downward along with the vertical rod 5. As a result, the bolt 11 and the jack 12 deviate, which will drive the wedge-shaped surface of the second abutting block 30 to abut against the wedge-shaped surface of the first abutting block 29, thereby driving the push rod 27 to move in the direction of the positioning hole 13, further stretching the third spring 32, and enabling the plurality of pushing portions 28 to be synchronously inserted into the respective positioning holes 13 and abut against the bolt 11 inside the positioning hole 13, so as to make the bolt 11 slide in the direction of the jack 12 and drive the elastic telescopic rod 19 to automatically reset. And since the bolt 11 is not coaxial with the jack 12 at this time, the abutment of the pushing portion 28 and the bolt 11 will make the second section 1102 abut against the side surface of the vertical rod 5, thereby causing the second section 1102 to slide into the first section 1101 and compress the second spring 25 to achieve avoidance. At this time, the bolt 11 is located between the pushing portion 28 and the vertical rod 5, and both ends of the bolt 11 are not inserted into the jack 12 and the positioning hole 13, that is, the top plate 8 is not connected to the sliding seat 9 and the vertical rod 5 at this time. The top plate 8 vertically moves downward under the action of its own gravity. At this time, the elastic force of the first spring 18 is released, thereby driving the transmission rod 23 and the abutting rod 24 away. The abutting rod 24 automatically resets under the action of the elastic force of the torsion spring. When the top plate 8 drives the bolt 11 to move to be coaxial with the jack 12, the elastic force of the second spring 25 is released, so that the second section 1102 is inserted into the jack 12 to realize the passive switching of the bolt 11 from the second state to the first state.

[0043] An extrusion plate 34 is elastically arranged on the support rod 16. A connecting frame 35 is arranged on the extrusion plate 34. The connecting frame 35 is provided with a third abutting block 36. A fourth abutting block 37 is arranged on the vertical rod 5. The third abutting block 36 is located on the movement stroke of the fourth abutting block 37. Specifically, a transverse groove 38 is formed at the top end of the top plate 8. The extrusion plate 34 is slidably connected with the transverse groove 38. Here, the elastic arrangement means that a fourth spring 39 is arranged between the extrusion plate 34 and the transverse groove 38. When the support rod 16 abuts against the connecting part 3, the extrusion plate 34 is located on one side of the terminal 2. The connecting frame 35 is sleeved outside the support rod 16. The third abutting block 36 is arranged on the lower surface of the connecting frame 35. The fourth abutting block 37 is arranged at the top end of the vertical rod 5. Wedge surfaces are arranged on both the third abutting block 36 and the fourth abutting block 37. The wedge surface of the third abutting block 36 is located on the movement stroke of the wedge surface of the fourth abutting block 37. Moreover, the fourth abutting block 37 is arranged to avoid the connecting part 3 and the cable, so as to avoid interference when the fourth abutting block 37 moves upward. The function of such an arrangement is that after the top plate 8 switches from the second position to the first position, it will not continue to move upward. However, the vertical rod 5 will continue to move upward under the action of the cylinder 7, so that the wedge surface of the fourth abutting block 37 abuts against the wedge surface of the third abutting block 36. Thus, under the action of the connecting frame 35, the extrusion plate 34 slides towards the position of the terminal 2 and stretches the fourth spring 39, so as to exert an extrusion effect on the terminal 2, making the terminal 2 tightly inserted into the interface, thereby preventing the terminal 2 from falling off. When the vertical rod 5 moves vertically downward, it will drive the fourth abutting block 37 and the third abutting block 36 away from each other. At this time, the elastic force of the fourth spring 39 is released, so that the extrusion plate 34 moves away from the terminal 2, so that the extrusion plate 34 and the third abutting block 36 are automatically reset.

[0044] Further, a locking rod 40 is arranged on the third abutting block 36, and a plurality of locking holes 41 are arranged on the support rod 16. Specifically, the locking rod 40 is fixedly connected to the surface of the third abutting block 36 close to the support rod 16 and is slidably connected with the side wall of the top plate 8. The plurality of locking holes 41 are uniformly arranged in the vertical direction of the support rod 16. When the fourth abutting block 37 abuts against the third abutting block 36 and drives the connecting frame 35 to move horizontally, the locking rod 40 will be inserted into one of the locking holes 41, thereby locking the position of the support rod 16. Thus, the elastic support of the support rod 16 becomes a fixed support. At this time, the elastic force of the first spring 18 will not be transmitted to the connecting part 3, so as to prevent the connecting part 3 from being always in a stressed state, thereby preventing the connecting part 3 from being damaged. After the fourth abutting block 37 and the third abutting block 36 move away from each other, the connecting frame 35 will drive the locking rod 40 to be pulled out of the locking hole 41 under the elastic force of the fourth spring 39 to realize the automatic reset of the locking rod 40.

[0045] Only some exemplary embodiments of the present invention have been described by way of illustration. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
