[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4The utility model provides a technical solution: a water-cooled cable joint structure, including a joint body 1, a cooling water pipe 2 and a plurality of wires 3. One end of the joint body 1 is provided with a cavity 4 for installing the end of the cooling water pipe 2. The joint body 1 is evenly distributed with a plurality of wire holes 5 for connecting the wires 3 around the outside of the cooling water pipe 2. The joint body 1 is provided with a locking mechanism for connecting the auxiliary wires 3. The locking mechanism replaces the original welding method. When part of the wires are damaged, they can be repaired after the locking is cancelled, which is convenient for the staff to carry out maintenance.

[0020] Specifically, the locking mechanism includes several groups of clamping plate assemblies 6 arranged corresponding to each wire hole 5, and the connector body 1 is provided with several squeezing assemblies 7 for squeezing adjacent clamping plate assemblies 6. The connector body 1 is provided with a driving assembly 8 for driving the several squeezing assemblies 7 to squeeze. The driving assembly 8 drives the squeezing assembly 7 to squeeze the clamping plate assembly 6, so that the clamping plate assembly 6 locks the wire 3. When part of the wire 3 is damaged, the driving assembly 8 drives the squeezing assembly 7 to cancel the locking of the clamping plate assembly 6, and maintenance can be carried out, which is convenient for the staff to perform maintenance.

[0021] Specifically, the clamping plate assembly 6 includes a fixed rod 6-1 arranged on the connector body 1, and two arc-shaped clamping plates 6-2 are rotatably installed on the fixed rod 6-1. The inner arc walls of the two arc-shaped clamping plates 6-2 are provided with anti-slip pads 6-3. The stability of the connection between the arc-shaped clamping plates 6-2 and the wire 3 is ensured by providing the anti-slip pads 6-3. After use, the adjacent clamping plate assemblies 6 are squeezed by the squeezing assembly 7, so that the two squeezing assemblies 7 squeeze the two arc-shaped clamping plates 6-2 to lock the wire 3.

[0022] Specifically, the extrusion assembly 7 includes a spring piece 7-1 arranged on the joint body 1, and an axe-shaped extrusion block 7-2 is provided at the end of the spring piece 7-1. After the driving assembly 8 is reversely driven, the axe-shaped extrusion block 7-2 is reset under the action of the spring piece 7-1, thereby automatically canceling the locking of the splint assembly 6 after the driving assembly 8 is reversely driven.

[0023] Specifically, the driving assembly 8 includes a sleeve 8-1 slidably mounted on the joint body 1, the inner wall of the sleeve 8-1 is provided with an inclined groove 8-2 for driving the extrusion assembly 7, and the end of the sleeve 8-1 away from the extrusion assembly 7 is rotatably mounted with a hand-held portion 8-3 threadedly connected to the joint body 1. When in use, the sleeve 8-1 is moved by rotating the hand-held portion 8-3, so that the inclined groove 8-2 on the sleeve 8-1 moves to drive the extrusion assembly 7 to be extruded, thereby realizing the extrusion of the splint assembly 6.

[0024] Specifically, the axe-shaped extrusion block 7-2 is provided with a resistance roller 7-3 that resists the inclined slide groove 8-2. The resistance roller 7-3 on the axe-shaped extrusion block 7-2 resists the inclined slide groove 8-2, thereby preventing the inclined slide groove 8-2 from generating a large friction force during the extrusion process of the extrusion component 7, thereby ensuring the service life of the locking mechanism.

[0025] Specifically, a plurality of strip slide grooves 9 are provided on the joint body 1, and there are four strip slide grooves 9. The interior of the sleeve 8-1 is provided with sliders 10 extending into the strip slide grooves 9, and there are four sliders 10, which ensures the stability of the sleeve 8-1 sliding on the joint body 1.

[0026] Working principle: During the use of the utility model, when part of the wire 3 is damaged, the drive assembly 8 is driven in reverse to move, and the extrusion assembly 7 is automatically reset to cancel the locking of the clamping plate assembly 6, so that it is convenient for the staff to carry out maintenance.
