[0034] like Figures 1 to 9As shown, applying the technical solution of the present invention, the insulating shield includes: a connecting tube 1, a metal disc 12, a metal rod 15, a metal disc 2 14, a compression spring 13, a stranded wire shaft 11, and a joint assembly 2. The metal disc 12 is fixedly disposed in the connecting tube 1. The metal rod 15 is fixedly connected to the metal disc 12. The metal rod 15 is disposed in the connecting tube 1 and extends along the axis of the connecting tube 1. The metal disc 2 14 is floatingly mounted on the metal rod 15. The compression spring 13 is connected between the metal disc 12 and the metal disc 2 14. The stranded wire shaft 11 is disposed on the side of the metal disc 2 14 facing away from the compression spring 13. The stranded wire shaft 11 is rotatably disposed in the connecting tube 1. The joint assembly 2 is movably disposed at the end of the connecting tube 1. The joint assembly 2 has a wire inlet connected to the interior of the connecting tube 1. The joint assembly 2 moves to drive the stranded wire shaft 11 to rotate. The stranded wire shaft 11 has a stranded state and a conductive state. When the stranded wire shaft 11 is in the stranded wire state, the connector assembly 2 moves toward the metal disc 12, and the wire enters the connecting tube 1 from the wire inlet and is wound around the stranded wire shaft 11. When the stranded wire shaft 11 is in the conductive state, the stranded wire shaft 11 is in contact with the metal disc 2 14. In this way, the cable is placed into the connecting tube 1 from the wire inlet, and the connector assembly 2 is driven to move toward the metal disc 12. When the connector assembly 2 moves, it can drive the stranded wire shaft 11 to rotate, so that the cable can be wound around the stranded wire shaft 11, so that the fixed connection between the cable and the stranded wire shaft 11 is more stable and reliable, reducing the possibility of loosening or detachment at the cable connection point, and making the operation of winding the cable around the stranded wire shaft 11 simple and quick, thereby improving work efficiency. The setting of the compression spring 13 enables the metal disc 2 14 to maintain contact with the stranded wire shaft 11, so as to facilitate the electrical connection between the metal disc 2 14 and the cable on the stranded wire shaft 11. In this way, one end of the cable to be connected is electrically connected to metal disc 12, and the other end of the cable to be connected is wrapped around the stranding shaft 11 and electrically connected to metal disc 12 via metal disc 2 14 and metal rod 15, thereby completing the cable wiring operation. Therefore, the technical solution of the present application effectively solves the problem in the related art that the wiring operation requires the operator to manually wrap the insulating tape around the cable, which is cumbersome and inefficient.

[0035] Furthermore, the connection tube 1 can protect the connection points of the cables, thereby reducing the possibility of damage caused by mice gnawing on them and preventing the connection points of the cables from becoming loose or falling off.

[0036] Going further:

[0037] like Figures 1 to 9As shown, in an optional embodiment, the joint assembly 2 includes a rectangular groove 21 opened inside the connecting tube 1 and a rectangular rod 22 slidably connected to the inside of the rectangular groove 21, a rectangular groove 23 is opened on the surface of the rectangular rod 22, and teeth 210 are fixedly connected to the inner wall surface of the rectangular groove 23 at equal intervals. One end of the stranded wire shaft 11 is fixedly connected to a gear 24, and the gear 24 is located inside the rectangular groove 23. The gear 24 is meshed with the rectangular rod 22 through the teeth 210.

[0038] A tension spring 25 is provided inside the rectangular groove 21, and the two ends of the tension spring 25 are fixedly connected to the bottom wall of the rectangular groove 21 and the first end of the rectangular rod 22 respectively; a limiting rope 26 is provided inside the rectangular groove 21, and the two ends of the limiting rope 26 are fixedly connected to the bottom wall of the rectangular groove 21 and the first end of the rectangular rod 22 respectively.

[0039] A compression spring 27 is provided in the circular groove 1 opened on the surface of the rectangular rod 22, and a limiting ball 28 is slidably connected in the circular groove 1 opened on the surface of the rectangular rod 22. One end of the compression spring 27 is fixedly connected to the limiting ball 28. A curved groove 1 and a curved groove 2 are opened on the side wall of the rectangular groove 1 21. The curved groove 1 and the curved groove 2 are spaced apart along the axial direction of the connecting pipe 1, and the limiting ball 28 can cooperate with the curved groove 1 or the curved groove 2 to limit the position.

[0040] The joint assembly 2 includes a guide bucket 29, which is fixedly arranged inside the connecting pipe 1. The wire inlet is arranged on the necking section of the guide bucket 29. The guide bucket 29 cooperates with the wire guide, and the wire inlet is arranged opposite to the stranding shaft 11.

[0041] like Figures 1 to 9 As shown, in this embodiment: when connecting two sections of cables, the rectangular rod 122 in the rectangular groove 121 is stretched toward the outside of the rectangular groove 121, so that the limiting ball 28 is pulled out of the curved groove 1 opened inside the connecting tube 1 by the tension force. Under the action of the elastic potential energy of the tension spring 125, the rectangular rod 122 moves toward the outside of the rectangular groove 121 until the limiting ball 28 is pushed into the curved groove 2 opened inside the connecting tube 1 by the compression spring 22. The limiting rope 26 prevents the rectangular rod 122 from being pulled out of the rectangular groove 121 by the large tension force. At this time, Insert the exposed cable parts of the cables at both ends into the connecting tube 1 respectively, guide the guide bucket 29 to make the cable parts pass through the stranding shaft 11 and squeeze the metal disc 2 14 on the surface of the metal disc 12 toward the direction of the metal disc 12, and then push the rectangular rod 1 22 toward the inside of the rectangular groove 21. During the movement, the rectangular rod 1 22 drives the stranding shaft 11 to rotate through the cooperation of the teeth 1 210 inside the rectangular groove 23 and the gear 1 24. At this time, the cable inside the stranding shaft 11 is entangled on the surface of the stranding shaft 11.

[0042] It should be noted that the curved groove 1 and the curved groove 2 are located inside the rectangular groove 1 21 to facilitate the insertion of the limiting ball 28 .

[0043] Going further:

[0044] like Figures 1 to 9 As shown, in an optional embodiment, the insulating shielding cover also includes a fixing assembly 3 connected to the joint assembly 2, the fixing assembly 3 includes a fixed coil 31 fixedly connected to the second end of the rectangular rod 22, a first arc-shaped clamping plate 321 and a second arc-shaped clamping plate 322 relatively arranged on the inner wall of the fixed coil 31, and a connecting piece connected between the connecting tube 1 and the second arc-shaped clamping plate 322, the first arc-shaped clamping plate 321 is fixedly arranged on the inner wall of the fixed coil 31, and the second arc-shaped clamping plate 322 is movably arranged on the inner wall of the fixed coil 31; the second arc-shaped clamping plate 322 has a clamping state moving toward the first arc-shaped clamping plate 321 and a releasing state moving away from the first arc-shaped clamping plate 321; when the fixing assembly 3 moves toward the metal disc 12, the connecting piece drives the second arc-shaped clamping plate 322 to switch to the clamping state.

[0045] A Y-shaped rod 33 is fixedly connected to the surface of the connecting tube 1, and a linkage rod 34 is provided inside the Y-shaped rod 33. The two ends of the linkage rod 34 are respectively fixedly connected to the first rotating rod 351 and the second rotating rod 352. The surface of the first curved splint 321 is fixedly connected to the fixed rod 37, and the fixed rod 37 is fixedly connected to the fixed coil 31. A telescopic rod 36 is provided on the surface of the second curved splint 322, and the telescopic rod 36 is fixedly connected to the fixed coil 31. The first rotating rod 351 is rotatably connected to the inside of the Y-shaped rod 33 through two bearings 2, and the second rotating rod 352 is rotatably connected to the groove 1 opened on the surface of the second curved splint 322 through two bearings 3.

[0046] When the first and second locking cams 321 and 322 are in the closed position, the first and second locking cams 322 are in the closed position, so that the first and second locking cams 321 and 322 can be locked together.

[0047] Going further:

[0048] like Figures 1 to 9 As shown, in an optional embodiment, the insulating shielding cover also includes a rodent-proof component 4 arranged on the circumferential outside of the connecting tube 1, the rodent-proof component 4 includes a pipe sleeve 41 fixedly connected to the outside of the connecting tube 1, a drug storage ring 43 fixedly connected to the outer surface of the connecting tube 1, and a moving block 42 movably arranged between the drug storage ring 43 and the pipe sleeve 41, the moving block 42 is sealed with the pipe sleeve 41, and a control spring 44 is provided inside the pipe sleeve 41, and the two ends of the control spring 44 are respectively fixedly connected to the pipe sleeve 41 and the moving block 42, and the control spring 44 applies a force to the moving block 42 in the direction away from the drug storage ring 43.

[0049] Among them, the moving block 42 moves to have a closed position and a released position; when the moving block 42 is in the closed position, the moving block 42 moves to the radial outside of the medicine storage ring 43, and the moving block 42 blocks and closes the medicine storage ring 43; when the moving block 42 is in the released position, the moving block 42 moves to one side of the medicine storage ring 43, and the moving block 42 avoids the medicine storage ring 43 to enable the medicine storage ring 43 to communicate with the outside.

[0050] The rodent-proof component 4 also includes a pressure-applying member that drives the movable block 42 to switch from the release position to the closed position; the pressure-applying member includes ventilation holes 45 provided in a circular array on the pipe sleeve 41, a sealing sleeve 46 fixedly connected to the pipe sleeve 41, a hollow sleeve 49 fixedly connected to the fixed coil 31, and a sealing plug 47 fixedly connected to the hollow sleeve 49. The interior of the ventilation hole 45 is fixedly connected to a ventilation pipe 48, which extends into the sealing sleeve 46. The sealing plug 47 is provided with a circular hole 2 that is connected to the hollow cavity of the hollow sleeve 49; when the sealing plug 47 is inserted into the sealing sleeve 46, the sealing plug 47 is sealed with the sealing sleeve 46, and the movable block 42, the pipe sleeve 41, the sealing sleeve 46, the sealing plug 47 and the hollow sleeve 49 form a closed space, and the air pressure in the closed space pushes the movable block 42 to switch from the release position to the closed position.

[0051] Thus, when fixed coil 31 is moved to connect with connecting pipe 1, sealing plug 47 and sealing sleeve 46 nest and seal together, compressing the air within hollow sleeve 49. This increases the air pressure within vent 45 of hollow sleeve 49 and pipe sleeve 41, pushing movable block 1 42 outward to block and seal drug storage ring 43. When a mouse bites through hollow sleeve 49, pipe sleeve 41, sealing plug 47, or sealing sleeve 46, the air pressure within vent 45 of hollow sleeve 49 and pipe sleeve 41 decreases, and movable block 1 42, under the force of control spring 44, moves to the release position, exposing the rat poison within drug storage ring 43 and thus protecting the insulating shield.

[0052] In this embodiment, the two cable segments to be connected are secured by a connector assembly 2. The securing assembly 3 protects the joint between the two cable segments from tension, thereby ensuring the stability of the connection. The rodent-proof assembly 4 exposes the rat poison stored within the cable joints when gnawed by rats, forcing the rats to consume the poison instead of gnawing at the joints, thus protecting the device.

[0053] The stranding shaft 11 includes a rotating shaft connected to the inner wall of the connecting tube 1 and a stranding frame connected to the rotating shaft. The stranding frame includes a first frame and a second frame connected to the first frame at an angle.

[0054] In this embodiment, the rat poison is stored in the medicine storage ring 43. When the limiting ball 28 moves from the curved groove 1 to the curved groove 2 in the connecting pipe 1, the sealing plug 47 on the hollow sleeve 49 and the sealing sleeve 46 on the pipe sleeve 41 move to separate, so that the air pressure inside the pipe sleeve 41 is reduced, so that the moving block 1 42 moves in the direction away from the medicine storage ring 43 under the action of the elastic potential energy of the control spring 44, thereby exposing the rat poison stored in the medicine storage ring 43. At this time, the rat poison inside the medicine storage ring 43 can be replaced or added. When the limiting ball 28 moves from the curved groove 2 to the curved groove 1 inside the connecting pipe 1, the sealing plug 47 on the surface of the hollow sleeve 49 is inserted into the interior of the sealing sleeve 46. At the same time, the two vent pipes 48 inside the sealing sleeve 46 are inserted into the sealing sleeve. The two circular holes 2 are opened on the surface of the sealing plug 47, and the two ventilation tubes 48 are respectively inserted into the interior of the hollow sleeve 49 through the two circular holes 3. At this time, the hollow sleeve 49 is connected with the interior of the pipe sleeve 41 through the ventilation hole 45 and the two ventilation tubes 48. In the process of inserting the sealing plug 47 into the interior of the sealing sleeve 46, the air pressure inside the pipe sleeve 41 increases, so that the moving block 1 42 overcomes the elastic potential energy of the control spring 44 inside the pipe sleeve 41 and moves toward the drug storage ring 43 until the two moving blocks 1 42 contact each other. At this time, the drug storage ring 43 is closed by the two moving blocks 1 42. When a mouse bites through the pipe sleeve 41 or any position on the surface of the hollow sleeve 49, the air pressure inside the pipe sleeve 41 decreases, so that the rat poison in the drug storage ring 43 is exposed, thereby protecting the device.

[0055] It should be noted that: the cross-sectional shape of the internal cavity of the tube sleeve 41 is a convex shape, which makes it convenient for the movable block 42 to be slidably connected to the tube sleeve 41 and the connecting pipe 1 at the same time. The movable block 42 is composed of an annular piece and a circular tube, which makes it convenient for it to slide inside the tube sleeve 41 while also making it convenient for the two movable blocks 42 to close the medicine storage ring 43 through the circular tube part. The movable block 42 always slides inside the tube sleeve 41, and the movable block 42 is in sealing contact with the tube sleeve 41. The cross-sectional shape of the medicine storage ring 43 is an I-shaped shape, which is convenient for the storage of rat poison. When the control spring 44 is in the natural state, the movable block 42 does not contact the medicine storage ring 43, which is convenient for the exposure of the rat poison in the medicine storage ring 43. The sealing sleeve 46 is composed of two coaxial circular tubes, which makes it convenient for the sealing plug 47 to be inserted into the interior of the sealing sleeve 46.

[0056] like Figures 1 to 9As shown, the working principle of this embodiment is as follows: the two sections of cables that need to be connected are fixed by the connector assembly 2, and the connector of the two fixed sections of cables is not easily subjected to tension by the fixing assembly 3, thereby ensuring the stability of the connection between the two sections of cables. When the connectors of the cables at both ends are gnawed by mice, the rat poison stored inside is exposed, so that the mice give up gnawing the connectors and eat the rat poison instead, thereby protecting the device. When the two sections of cables are connected, the rectangular rod 22 in the rectangular groove 21 is stretched toward the outside of the rectangular groove 21, so that the limiting ball 28 is pulled out of the curved groove 1 opened inside the connecting tube 1, and under the action of the elastic potential energy of the tension spring 25, the rectangular rod 22 moves toward the outside of the rectangular groove 21 until it is The limiting ball 28 is pushed into the curved groove 2 opened inside the connecting tube 1 by the compressed spring 27, and the limiting rope 26 prevents the rectangular rod 12 from being pulled out of the rectangular groove 21 by a large pulling force. At this time, the exposed cable parts of the cables at both ends are respectively inserted into the interior of the connecting tube 1, and the cable parts are guided by the guide bucket 29 to pass through the stranding shaft 11 and the metal disc 2 14 is squeezed on the surface of the metal disc 12 toward the direction of the metal disc 12, and then the rectangular rod 22 is pushed toward the inside of the rectangular groove 21. During the movement, the rectangular rod 22 drives the stranding shaft 11 to rotate through the cooperation of the teeth 210 and the gear 24 inside the rectangular groove 23. At this time, the cable inside the stranding shaft 11 is entangled on the surface of the stranding shaft 11, and moves away from the connecting tube 1. When the rectangular rod 22 is pulled in the right direction, the fixed coil 31 moves in the direction away from the connecting tube 1, so that the linkage rod 34 in the Y-shaped rod 33 rotates around the central axis of the first rotating rod 351 and the second rotating rod 352 respectively, until the limiting ball 28 enters the interior of the curved groove 2 opened in the connecting tube 1. This process causes the first curved splint 321 and the second curved splint 322 to move toward each other under the cooperation of the fixed rod 37 and the two telescopic rods 36, and finally makes the distance between the first curved splint 321 and the second curved splint 322 convenient for the cable to pass through the interior of the fixed coil 31. When the rectangular rod 22 moves toward the interior of the rectangular groove 21 until the limiting ball 28 enters the interior of the curved groove 1 opened in the connecting tube 1, the first curved splint 321 The second arc-shaped clamping plate 322 clamps the outer sheathed portion of the cable, so that the joint of the two cable sections is not easily stressed, thereby ensuring the stability of the cable joint. The rat poison is stored in the medicine storage ring 43. When the limiting ball 28 moves from the curved groove 1 to the curved groove 2 in the connecting tube 1, the sealing plug 47 on the hollow sleeve 49 and the sealing sleeve 46 on the pipe sleeve 41 move to separate, so that the air pressure inside the pipe sleeve 41 is reduced, so that the moving block 1 42 moves in the direction away from the medicine storage ring 43 under the action of the elastic potential energy of the control spring 44, thereby exposing the rat poison stored in the medicine storage ring 43. At this time, the rat poison inside the medicine storage ring 43 can be replaced or added. When the limiting ball 28 moves from the curved groove 2 to the curved groove 1 inside the connecting tube 1,The sealing plug 47 on the surface of the hollow sleeve 49 is inserted into the interior of the sealing sleeve 46. At the same time, the two vent tubes 48 located inside the sealing sleeve 46 are inserted into the two circular holes 2 opened on the surface of the sealing plug 47. The two vent tubes 48 are respectively inserted into the interior of the hollow sleeve 49 through the two circular holes 3. At this time, the hollow sleeve 49 is connected to the interior of the pipe sleeve 41 through the vent hole 45 and the two vent tubes 48. During the process of the sealing plug 47 being inserted into the interior of the sealing sleeve 46, the air pressure inside the pipe sleeve 41 increases, causing the movable block 1 42 to overcome the elastic potential energy of the control spring 44 inside the pipe sleeve 41 and move toward the drug storage ring 43 until the two movable blocks 1 42 contact. At this time, the drug storage ring 43 is sealed by the two movable blocks 1 42. When a mouse bites through the pipe sleeve 41 or any position on the surface of the hollow sleeve 49, the air pressure inside the pipe sleeve 41 decreases, exposing the rat poison in the drug storage ring 43, thereby protecting the device.

[0057] Compared with the prior art, the beneficial effects of the present invention are: a connector assembly 2, a fixing assembly 3 and a rodent-proof assembly 4 are provided, so that the device can better protect the cable connection points through the cooperation of the connector assembly 2, the fixing assembly 3, the rodent-proof assembly 4 and the metal disc 12, thereby improving the drag resistance of the cable joints and giving the cable joints the function of preventing and killing rodents.
