[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Refer to the instruction manual appendix Figure 1-7 An embodiment of the present invention provides a cable connection protection connector, such as... Figure 1 and Figure 5 As shown, it includes two end positioning mechanisms 1; multiple synchronous connecting rods 2 are fixedly connected between the two end positioning mechanisms 1, and two limit sleeves 3 are fixedly installed on the outer wall of each of the multiple synchronous connecting rods 2, and a central protective mechanism 4 is slidably installed on the outer wall of the multiple synchronous connecting rods 2.

[0017] Reference Figure 6-7As shown, the central protective mechanism 4 includes a protective housing 41 that is slidably installed on the outer wall of multiple synchronous connecting rods 2. Multiple air storage chambers 43 are opened inside the protective housing 41. Multiple sealing sleeves 44 that communicate with the air storage chambers 43 are fixedly installed on both sides of the protective housing 41. An air baffle plate 45 is fixedly installed at the vertical center line position of each air storage chamber 43 to divide the inner cavity of the air storage chamber 43 into two parts.

[0018] Piston rods 46 extending into the inner cavity of the air storage chamber 43 are inserted into the sealing sleeves 44 on both sides of the protective housing 41. A sliding sleeve 410 that is slidably connected to the synchronous connecting rod 2 is fixedly installed at one end of the piston rod 46 extending out of the outer wall of the sealing sleeve 44. A return spring 411 that is fixedly connected to the air baffle plate 45 is fixedly installed at the other end of the piston rod 46 extending into the inner cavity of the air storage chamber 43. Under normal conditions, both return springs 411 are in a contracted state, and both piston rods 46 move at the vertical centerline position inside the two air storage chambers 43 separated by the air baffle plate 45. The two limiting sleeves 3 provided on each synchronous connecting rod 2 are also symmetrically arranged about the vertical centerline of the protective housing 41.

[0019] When the synchronous link 2 moves, it synchronously drives the end positioning mechanism 1 at both ends to move on the outer wall of the cable. At the same time, when the limiting sleeve 3 on one side comes into contact with the sliding sleeve 410 and synchronously presses against the piston rod 46 on the corresponding side to move away from the air-blocking plate 45, the piston rod 46 on the other side contracts in conjunction with the elastic restoring force of the return spring 411 and moves into the inner cavity of the air storage chamber 43.

[0020] Two air guide pipes 47, which are connected to the air storage chamber 43, are fixedly installed on the inner wall of the protective shell 41. A connecting pipe 49 is provided between the two air guide pipes 47, and multiple airbag strips 48 are connected in a ring-shaped manner with equal spacing on the outer wall of the two air guide pipes 47. The two air guide pipes 47 are arranged symmetrically about the vertical center line of the air baffle plate 45.

[0021] Specifically, a one-way valve is provided on the piston part of the piston rod 46. When the piston rod 46 approaches the air baffle plate 45, the one-way valve on the piston part closes, and when the piston rod 46 moves away from the air baffle plate 45, the one-way valve on the piston part opens. A one-way valve is also provided at the connection between the gas storage chamber 43 and the gas guide pipe 47. When gas flows from the gas storage chamber 43 to the gas guide pipe 47, the one-way valve at the connection opens, and when gas flows from the gas guide pipe 47 to the gas storage chamber 43, the one-way valve at the connection closes.

[0022] Understandably, when splicing two cables is required, the cables can be passed through the inner cavity of the protective housing 41. Two air ducts 47 surround the splice of the cables, and multiple airbag strips 48 are evenly distributed around the outer periphery of the splice. Regardless of which side of the air baffle plate 45 the piston rod 46 moves towards the air baffle plate 45, the gas in the corresponding cavity can be squeezed into the inner cavity of the air duct 47, and the gas can enter the multiple airbag strips 48. After expansion, the gas fully presses against and limits the cable's outer wall. Thus, when the cable is affected by external forces, the central protective mechanism 4 can not only buffer the axial direction of the cable connection, but also apply a clamping force to the radial circumference of the relatively weak cable connection through the air ducts 47 and airbag strips 48, thereby enhancing the connection strength of the cable connection in real time, reducing the risk of circuit breakage caused by loosening of the connection, and improving the stability of the power system.

[0023] Furthermore, in combination Figure 5-6 As shown, the two end positioning mechanisms 1 include fixed chucks 101 fixedly connected to both ends of multiple synchronous connecting rods 2 respectively. Each of the two fixed chucks 101 has a rotating chuck 102 rotatably connected to the side of the synchronous connecting rod 2. The interior of each of the two rotating chucks 102 is provided with a positioning component for clamping the cable. In actual use, after the two cables are connected, they pass through the inner cavity of the two fixed chucks 101, the rotating chuck 102 and the protective housing 41 in sequence. The connection head is limited and covered by the protective housing 41.

[0024] Among them, combined Figure 4 As shown, the centers of the protective housing 41, the fixed chuck 101, and the rotating chuck 102 are all on the same horizontal line. The purpose of this arrangement is to ensure that the two fixed chucks 101 and the rotating chuck 102 at both ends of the protective housing 41 are all limited and covered on the outer walls of the two cables, keeping both ends of the two cables on the same horizontal line, thereby maintaining the stability of the connection between the two cables.

[0025] Meanwhile, multiple elastic pressure plates 42 are hinged to both ends of the protective housing 41, and the multiple elastic pressure plates 42 are arranged in a ring-shaped, equidistant manner around the inner circumference surface of the protective housing 41. In actual use, depending on the thickness of the cable, after passing the two connected cables through the interior of the protective housing 41, the multiple elastic pressure plates 42 at both ends are adjusted to conform to the outer surface of the cable and evenly adhere to the outer wall of the cable. Then, by wrapping the multiple elastic pressure plates 42 with insulating waterproof tape, they are fixed to the outer wall of the cable. This allows the protective housing 41 to stably limit and cover the connection of the two cables, providing anti-collision and anti-displacement protection for the connection of the two cables.

[0026] In practice, after the two cables are connected, they are passed through the inner cavities of the two fixed chucks 101, the rotating chuck 102, and the protective housing 41 in sequence. Then, according to the length of the two cables, the synchronous connecting rod 2 is moved to the outer wall of its two end positioning mechanisms 1 on the two cables. After the two end positioning mechanisms 1 are adjusted to the appropriate positions of the two cables, multiple elastic pressure plates 42 are wrapped around the outer wall of the cables with insulating waterproof tape, so that the connection of the two cables can be protected and limited.

[0027] As a further expansion of this plan, refer to Figure 2-3 As shown, the positioning assembly includes multiple sliding grooves 103 formed on the outer wall of the rotating chuck 102. Movable support rods 104 are rotatably mounted inside the inner cavities of each sliding groove 103, and sliding brackets 105 are slidably mounted on the outer walls of each movable support rod 104. A fixed support rod 106, fixedly connected to the fixed chuck 101, is rotatably mounted on one side of each sliding bracket 105. An anti-slip pressure plate 107 is rotatably connected to the side of each sliding bracket 105 away from the fixed support rod 106. In actual use, rotating the rotating chuck 102 allows the movable support rods to... The displacement of 104 causes the sliding bracket 105 to slide on its outer wall, and changes the tilt angle of the sliding bracket 105. This causes multiple sliding brackets 105 to move closer to or further away from the center of the rotating chuck 102 in sync, thereby enabling real-time clamping and limiting according to the different thicknesses of the cables, thus maintaining the stability of both sides of the two cables. When the two cables are pulled by external force, the fixed connection with the synchronous link 2 ensures that the two cables always maintain synchronous movement, thereby avoiding the problem of loosening at the connector caused by external force pulling the cables.

[0028] Multiple sliding brackets 105 and anti-slip pressure plates 107 are arranged in a ring-shaped, equidistant manner around the inner circumference of the rotating chuck 102. The purpose of this arrangement is to ensure that the multiple sliding brackets 105 and anti-slip pressure plates 107 are uniformly positioned and pressed against the outer wall of the cable, so that the outer wall of the cable is subjected to balanced force, thereby maintaining positioning stability.

[0029] Multiple synchronous linkages 2 are arranged in a ring-shaped, equidistant manner around the outer wall of the rotating chuck 102, and the multiple synchronous linkages 2 are fixedly connected to the rotating chuck 102. The purpose of this arrangement is to enable the multiple synchronous linkages 2 and the protective housing 41 to rotate synchronously when the rotating chuck 102 is rotated.

[0030] Furthermore, a connecting turntable 108 is fixedly installed on one side of the rotating chuck 102 and is rotatably connected to the fixed chuck 101. The outer wall of the connecting turntable 108 is provided with a plurality of arc-shaped limiting grooves 109. A plurality of fixed support rods 106 pass through the limiting grooves 109 and are fixedly connected to the fixed chuck 101. The purpose of this arrangement is to ensure that when the rotating chuck 102 is rotated, the connecting turntable 108 rotates synchronously on one side of the fixed chuck 101. Moreover, when the connecting turntable 108 and the rotating chuck 102 are rotated and adjusted as a whole, the setting of the limiting grooves 109 will not affect the position of the fixed support rods 106.

[0031] Meanwhile, fixed brackets 111 are hinged to the side of the fixed chuck 101 away from the rotating chuck 102. Multiple locking holes 110 are provided in a ring-shaped, equidistant manner around the circumference of both the fixed chuck 101 and the connecting turntable 108. In actual use, after adjusting the overall position of the fixed chuck 101 and the rotating chuck 102, the rotating chuck 102 and the connecting turntable 108 are rotated so that the positioning component is clamped on the outer wall of the cable. The locking bolt is then passed through the locking holes 110 provided on the connecting turntable 108 and the fixed chuck 101 to fix the position of the rotating chuck 102, thereby fixing the clamping position of the positioning component.

[0032] Alternatively, the mounting bracket 111 can be fixed to the wall by tightening bolts to position and install the two cables, thereby maintaining the stability of the cable connection.

[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
