The working principle of the invention for the liquid metal based cable connection assembly is as follows:

when two cables 3 need to be connected, firstly, the two cables 3 penetrate through the installation ring 5 and enter the fixed ring 2 and the square tube 1, meanwhile, the metal core 4 enters between the two clamping plates 13, the starting cylinder 8 drives the push plate 9 to move and extrude the cables 3 to be fixed, the two cables 3 and the metal core 4 are driven to move towards the central point of the two clamping plates 13 by rotating the two screwed tubes 6, the installation ring 5 drives the first sliding rod 10 to move and enter the first sliding groove 11 to limit the cables 3, meanwhile, the two cables 3 push the sliding block 18 to slide and simultaneously extrude the second spring 19, the sliding block 18 drives the triangular block 20 to move, so that the triangular block 20 enters the triangular groove 15, thrust is generated through the oblique angles between the triangular block 20 and the triangular groove 15, the telescopic rod 12 extends, meanwhile, the first spring 14 generates pressure, and finally, the two clamping plates 13 approach each other until the metal core 4 is clamped tightly, the fixing is done and the power transfer can be done by the mutual contact of the two metal cores 4 or the metal conductive plates.

the invention provides a cable connecting assembly based on liquid metal, which can simply and conveniently connect and fix cables and reduce unnecessary mounting holes by mutually matching a cable 3, a mounting ring 5, a fixing ring 2, a metal core 4, a clamping plate 13, a cylinder 8, a push plate 9, a threaded pipe 6, a first sliding rod 10, a sliding block 18, a second spring 19, a triangular block 20, a triangular groove 15, a telescopic rod 13, a first spring 14 and the clamping plate 13, and has the advantages of convenience in connection and fixation and high safety.

In the process of cable connection, the connection reliability and the connection resistance at the connection position are generally factors which must be considered, the reliability and the connection resistance directly determine the quality of the connection effect, and the disconnection, unstable connection or non-tight connection and other conditions are usually generated at the connection position, so that the poor conduction effect and the large contact resistance at the connection position are caused, and at the moment, a large amount of heat is generated due to the large resistance, so that the whole device is in failure, and the material at the outer edge is likely to age to cause fire and other conditions in serious cases, therefore, the middle part of the splint is also provided with an accommodating cavity which is filled with liquid metal, the liquid metal is conductive metal, an opening is arranged at the position, corresponding to the accommodating cavity, on the inner side of the splint, the opening is hermetically connected through a conductive first elastic layer, and one side of the first elastic layer, which is close to the metal core, is provided with an elastic metal conductive, the elastic layer is electrically connected with the metal conductive plate, the side edge of the clamping plate forming the triangular groove is connected with the second elastic layer, the position, not the opening, in the clamping plate is connected with a vertical fixing plate, after the triangular block enters the bottom of the triangular groove, the triangular block can extrude the containing groove by continuously pushing, so that the liquid metal in the containing groove can extrude and push the first elastic layer and the metal conductive plate to be close to the metal core through the opening, the metal core positioned in the square tube is connected with the conductive post, two ends of the conductive column are respectively connected with the metal cores of the two cables, the holding groove can be extruded by the continuous pushing of the triangular block, so that the liquid metal in the accommodating groove can extrude and push the first elastic layer and the metal conductive plate to approach the conductive post through the opening. The same as the above, the difference is that the second elastic layer is arranged on the clamping plate side of the besieged triangular groove 15, when the triangular block 20 is close to the triangular groove 15, the second elastic layer can be extruded to a certain degree, but the extrusion will not destroy the compression effect of the first spring 14, or the compression effect of the first spring 14 is not good when the second elastic layer is not arranged, but the compression effect of the first spring 14 can still be realized, so that the clamping plate 13 can still extrude and fix the metal core 4, especially when the triangular block 20 completely fills the triangular groove 15, the size of the triangular block 20 can be set to be slightly larger or larger than that of the triangular groove, so that the triangular block 20 can be continuously pushed to extrude the triangular groove after the triangular groove 15 is completely filled by the triangular block 20, because the effect of first elastic layer, second elastic layer makes liquid metal in the storage tank can be by the maximum compressed, make electrically conductive liquid metal, electrically conductive first elastic layer, electrically conductive metal sheet can with metal core 4 and/or lead electrical pillar to can guarantee that the pressure of junction position department through liquid metal makes and realizes reliably connecting, simultaneously because all be formed with liquid metal, metal conductive plate and at every junction position and whole splint 13 inboard the parallelly connected effect of metal core 4 and electrically conductive post makes whole junction reduce contact resistance, has greatly improved electrically conductive effect and electrically conductive reliability.
