[0016] The utility model will be further explained in connection with the drawings:

[0017] Referring to the drawings: this anti -drop cable joint, including main part 1 and setting at the interface end of main part 1 is used to reduce the interface diameter's screw nut 2, main part 1 is set with the abutment block 3 in the middle part non -interface end, and the non -interface end is set with the locking bushing 4 of using with abutment block 3 cooperation to keep main part 1 on the terminal box, and the inner periphery of locking bushing 4 is provided with two oppositely arranged clamping rods 41, and main part 1 forms the clamping end point 11 that defines the final assembly position of locking bushing 4 on main part 1 and matches clamping rod 41 at non -interface end, and the pointing channel 12 that guiding clamping rod 41 reaches clamping end point 11 is provided on main part 1, and the elastic component 5 that is set on main part 1 and can retract under extrusion is between abutment block 3 and locking bushing 4, and elastic component 5 is extruded and retracted when being set on the terminal box on main part 1 and generates the abutment degree of force that clamping rod 41 is limited in clamping end point 11. The principle of the utility model lies in, when main part 1 is set on the terminal box, main part 1 passes through the mounting hole on the terminal box, and abutment block 3 is in abutment with the outer surface on the terminal box, then elastic component 5, locking bushing 4 are inserted on main part 1, which utilizes the combination of clamping rod 41 and clamping end point 11 to make locking bushing 4 keep on main part 1, and make elastic component 5 extrude and retract deformation, and after extruding and retracting deformation, it can produce the abutment degree of force and limit clamping rod 41 in clamping end point 11, to prevent locking bushing 4 from separating from main part 1, so that main part 1 is stably set on the terminal box, and by such mode, the locking bushing 4 is kept on main part 1 by the threaded cooperation mode as prior art, so that the tool-free operation mode is assembled, is suitable for quick assembly and convenient assembly.

[0018] The directional channels 12 have two and are arranged opposite to each other, including a first directional channel 12-1, a second directional channel 12-2, and a third directional channel 12-3. The clamping rod 41 passes through the first directional channel 12-1, the second directional channel 12-2, and the third directional channel 12-3 to reach the clamping end point 11. The locking sleeve 4 rotates by utilizing the movement of the clamping rod 41 in the corresponding second directional channel 12-2. Such an arrangement enables the locking sleeve 4 to be inserted into the main body 1 at the same time as the clamping rod 41 also enters the first directional channel 12-1, and then enters the second directional channel 12-2 and the third directional channel 12-3 in sequence to reach the clamping end point. 11, thereby realizing a tool-free assembly operation mode, which is suitable for quick and convenient assembly, and also extends the total length of the route for the clamping rod 41 to reach the clamping end point 11, which can increase the difficulty of the clamping rod 41 to escape. At the same time, the first directional channel 12-1 and the third directional channel 12-3 are vertically arranged in the same direction as the insertion direction of the locking sleeve 4, and the second directional channel 12-2 is horizontally arranged, so the locking sleeve 4 and the main body 1 are both arranged into coaxial columns, so that when the clamping rod 41 moves in the second directional channel 12-2, the locking sleeve 4 rotates, thereby switching from the first directional channel 12-1 to the second directional channel 12-3.

[0019] The two second directional channels 12-2 located at different positions extend in different lateral directions to match the rotational movement of the locking sleeve 4. This setting takes into account that the two clamping rods 41 will follow the corresponding changes after the locking sleeve 4 rotates, that is, one of the clamping rods 41 moves to the left and the other of the clamping rods 41 moves to the right. In this way, the two second directional channels 12-2 extend in different directions on both sides to meet the changes of the two clamping rods 41 following the rotation of the locking sleeve 4.

[0020] The first directional channel 12-1 and the second directional channel 12-2, the second directional channel 12-2 and the third directional channel 12-3 are provided with a turning channel 12-4 on the main body 1 to guide the connecting rod 41 from the first directional channel 12-1 to the second directional channel 12-2, and from the second directional channel 12-2 to the third directional channel 12-3. The first directional channel 12-1, the second directional channel 12-2, and the third directional channel 12-3 basically extend in a straight line, while the turning channel 12-4 basically extends in an arc. Therefore, when the connecting rod 41 slides in the turning channel 12-4, the corresponding turning assembly direction is an arc-shaped direction, which can be clearly felt by the user and will play a corresponding prompting role, so that the user can predict that the turning channel 12-4 is about to be reached, which also means that the connecting rod 41 has entered the turning channel 9, which can avoid user misjudgment.

[0021] The turning channel 12-4 is formed with a fitting wall 12-41 that completely fits on the partial surface of the clamping rod 41 when the clamping rod 41 reaches the turning channel 12-4, so that the clamping rod 41 is accurately positioned in the turning channel 12-4 to match the accuracy of the clamping rod 41 entering the second pointing channel 12-2 or the third pointing channel 12-3.

[0022] The elastic assembly 5 is arranged as a spring, one end of the spring abuts against the inner surface of the terminal box when the main body 1 is arranged on the terminal box, and the other end of the spring abuts against the locking sleeve 4, the spring has a retractable characteristic under extrusion, the extrusion retraction occurs when the locking sleeve 4 is arranged on the main body 1, that is, the spacing between the locking sleeve 4 and the inner surface of the terminal box is less than the initial length of the spring, and the spring can generate elasticity to reset itself after being extruded, but the spring cannot recover to the initial length under the position limitation of the locking sleeve 4, so that the elasticity can be converted into an abutting force, the clamping rod 41 is limited in the clamping end point 11, and the pitch between the springs is small, so that the spring has a certain deformation resistance, that is, a certain acting force is required to trigger the spring deformation, so that the joint is stably arranged on the terminal box.

[0023] Although the utility model has been illustrated and described by referring to the preferred embodiments, it should be understood by those skilled in the art that various changes in form and details can be made within the scope of the claims.
