[0036] like Figure 1-8 As shown, an embodiment of the present invention provides a cable connector, including a mounting shell 1, the mounting shell 1 has three arc-shaped two sides, and the two sides of the mounting shell 1 are respectively connected with a first connecting shell 2 and a second connecting shell 3 with an arc-shaped arrangement;

[0037] In the technical solution of this embodiment, by providing three installation shells 1, the three wires inside the cable can be butted and installed. By placing two wires that need to be connected together at the two sides of the installation shell 1 respectively, and butting and fixing the two sides of the installation shell 1 by the first connection shell 2 and the second connection shell 3, the connection and installation operation of the wires can be achieved;

[0038] like Figure 2 , Figure 3 and Figure 8 As shown, a clamping plate 4 is installed on the inner side wall of the first connection shell 2, the second connection shell 3 and the installation shell 1. The clamping plate 4 is arranged in an arc shape and a plug rod 23 is fixedly connected to the side wall. A slot 24 is opened on the inner wall of the first connection shell 2, the second connection shell 3 and the installation shell 1. The plug rod 23 matches the slot 24 and the plug rod 23 is inserted into the slot 24.

[0039] In the technical solution of this embodiment, when the cable conductors are butt-jointed and installed, the operator can select a clamping plate with a plug rod 23 of a suitable length according to the wire diameter of the wire, and then insert the plug rod 23 into the slot 24 on the inner wall of the first connection shell 2, the second connection shell 3 and the installation shell 1, so as to realize the installation operation of the clamping plate 4. At this time, when the first connection shell 2, the second connection shell 3 and the installation shell 1 are butt-jointed and installed, the clamping plate 4 can be used to realize the butt-jointing and fixing operation of the cable conductors of different wire diameters of the present cable connector, thereby improving the adaptability of the installation;

[0040] like Figure 1 and Figure 2 As shown, a positioning and mounting assembly 5 is provided on the first connecting shell 2, the second connecting shell 3 and the mounting shell 1, and the positioning and mounting assembly 5 includes a fixing plate 8, and the fixing plates 8 are fixedly connected to the side walls of both sides of the first connecting shell 2, the second connecting shell 3 and the mounting shell 1, and a plurality of fixing screws 9 are passed through the fixing plate 8, and a fixing nut 10 is threadedly connected to one end of the fixing screw 9;

[0041] In the technical solution of this embodiment, after the first connection shell 2, the second connection shell 3 and the installation shell 1 complete the clamping and fixing of the internal wires of the cable, the positioning operation between the three fixing plates 8 on the same side can be achieved by passing the fixing screws 9 through the same three fixing plates 8, and the locking between the first connection shell 2, the second connection shell 3 and the installation shell 1 can be achieved by tightening the fixing nuts 10 on the fixing screws 9, so that the cable wires can be stably and securely docked and installed together, which is convenient for installation and use;

[0042] like Figure 4 and Figure 6 As shown, a conductive connection assembly 6 is disposed in the inner cavity of each mounting shell 1, and the conductive connection assembly 6 includes a threaded rod 11, and a plurality of truncated cone blocks 12 are evenly distributed and threadedly connected on the side wall of the threaded rod 11, and two conductive rods 13 are symmetrically and movably connected to the truncated cone blocks 12, and one end of the conductive rod 13 away from the truncated cone blocks 12 penetrates the side wall of the mounting shell 1, and a worm gear 14 is fixedly connected at one end of the threaded rod 11, and a worm 15 is meshed on the worm gear 14, and the worm 15 penetrates the side wall of the mounting shell 1 and is movably connected to the mounting shell 1;

[0043] In the technical solution of this embodiment, before connecting the cable conductor, the operator needs to measure the insulation thickness of the internal conductor of the cable. After measuring the insulation thickness data, the operator rotates the worm 15, the worm 15 engages the turbine 14 to rotate, the turbine 14 drives the threaded rod 11 to rotate, the threaded rod 11 engages the truncated cone block 12 to move, and the length of the conductive rod 13 extending to the inside of the installation shell 1 can be controlled by moving the truncated cone block 12. When the conductive rod 13 extends to a length that is sufficient to penetrate the insulation layer and is in firm contact with the internal conductor, the operator stops rotating the worm 15. As the above principle, the cable connector can realize the connection and installation of conductors with different insulation thicknesses, which can not only effectively improve the convenience of cable connection, but also improve the versatility of cable connection.

[0044] like Figure 6 As shown, further, two inclined grooves 25 are symmetrically provided on the outer side wall of the truncated cone block 12, and a slider 26 is installed on one end of the conductive rod 13 close to the truncated cone block 12, and the slider 26 is movably connected to the inclined groove 25. The truncated cone block 12 is driven to operate by the threaded rod 11, so that the slider 26 can be moved in the shoe groove 25, which is convenient for adjusting the position of the conductive rod 13 and convenient for adapting to different thicknesses of insulating skin for conductive use;

[0045] like Figure 6As shown, further, one end of the worm 15 away from the worm wheel 14 extends out of the mounting housing 1 and is provided with a groove 27, the groove 27 is arranged in a regular hexagon, and the groove 27 is arranged corresponding to the hexagonal wrench, and the worm 15 can be rotated and adjusted by the hexagonal wrench, which is convenient for operation;

[0046] like Figure 1 and Figure 7 As shown, a combined connection assembly 7 is arranged between several second connection shells 3, and the combined connection assembly 7 includes a mounting groove 16. The second connection shells 3 are all provided with mounting grooves 16, and connecting screws 17 are inserted into the mounting grooves 16. The connecting screws 17 are threadedly connected with connecting nuts 18 and threaded sleeves 19, and the threaded sleeves 19 are fixedly connected with a concentrically arranged positioning sleeve 20 at one end away from the connecting screw 17. The same positioning rod 21 is sleeved on several positioning sleeves 20, and both ends of the positioning rod 21 are threadedly connected with positioning bolts 22. The inner side wall of the positioning sleeve 20 is arranged in a regular hexagonal shape, and the outer wall of the positioning rod 21 is a regular hexagon with the positioning sleeve 20 and is matched with the positioning sleeve 20;

[0047] In the technical solution of the present embodiment, because the connection operation between the cables with three conductors is adopted, after the cable conductors are connected in pairs by installing the shell 1, the first connecting shell 2 and the second connecting shell 3, the connected conductors are distributed and arranged, and the threaded sleeve 19 is rotated so that the connecting screw 17 is rotated out of the specified length, so that the positioning sleeves 20 can be placed together and the inside of the positioning sleeves 20 is penetrated, and the positioning rod 21 is passed through both sides to obtain the positioning sleeves 20, and the positioning bolts 22 are tightened at both ends of the positioning rod 21, and the positioning bolts 22 are used to limit the forward and backward movement of the positioning sleeve 20, so as to complete the forward and backward position positioning of the cable connector, and because the positioning sleeve 20 and the positioning rod 21 are both arranged in a regular hexagon, the cable connection rotation is limited, and the various connecting conductors can be evenly distributed and arranged to avoid mutual influence at the connecting point of the conductors, thereby improving the stability of the cable connection, and the insulation effect of the cable connection can be further improved by setting a mold on the outside and injecting insulating material into the mold, thereby improving the stability and safety of the cable connection.

[0048] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details.
