The heat-shrinkable cable sleeve at the connector is then heated using a heating device or blowtorch to allow it to adhere to the cable and form a cable connector. However, existing cable connectors cannot quickly and accurately connect to the cable after they are formed, resulting in an unstable cable connection that affects the subsequent use of the cable.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] To address the problems existing in the prior art, this embodiment provides a high-strength heat-shrinkable cable intermediate joint, comprising a joint body 1 and a precision fixing mechanism 2. The precision fixing mechanism 2 is located on the left and right sides of the outside of the joint body 1, enabling the joint body 1 to be firmly fixed to the cable. At the same time, a reinforcement mechanism 3 is provided, which is installed outside the precision fixing mechanism 2, thereby further improving the stability of the joint body 1 and the cable installation.

[0027] like Figure 2 , Figure 5 and Figure 6 As shown, the existing connector body 1 adopts a double-layer insulation structure, including components such as conductor connecting tube, stress composite tube and inner and outer insulation tube, which has excellent tensile strength and mechanical protection capability. After the cable outer sheath is peeled off and the internal core is connected, a special connector body 1 needs to be put on. The connector body 1 is put on the connector position, and the connector body 1 is heated to shrink and tightly adhere to the cable to form a sealing layer to become a cable connector, which can then be connected to the cable.

[0028] After the connector body 1 is attached to the cable connector, the mounting rings 21 are symmetrically engaged on the left and right sides of the connector body 1. Bolts 22 are then inserted into the mounting rings 21 and tightened for fixation. The collar 23 is then fitted onto the left and right sides of the connector body 1. Threaded pins 24, symmetrically installed on the inner side of the collar 23, are inserted into the mounting ring 21. Nut sleeves 25 are then threaded into the inner ends of the threaded pins 24. The nut sleeves 25 are located inside the mounting ring 21, ensuring a firm fit between the collar 23 and the mounting ring 21. Furthermore, engagement teeth 26 are provided on the outer end of the collar 23, and the outer and inner sides are fitted with… The first sealing ring 27 is basically the same as the component installed on the outside of the connector body 1 on the outside of the cable to be connected. The position of the toothed groove of the fitting tooth 26 is staggered with the corresponding position of the fitting tooth 26 on the outside of the connector body 1, so that the cable to be connected can contact the two sides of the connector body 1. That is, the fitting tooth 26 on the outside of the connector body 1 can be firmly engaged with the fitting tooth 26 on the outside of the cable. At the same time, the first sealing ring 27 will also engage with the inside of the collar 23 on the outside of the cable. After the fitting tooth 26 is engaged, the first sealing ring 27 will be engaged between the collar 23, which can enhance the sealing of the connection.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, after the connector body 1 and the cable are engaged and connected by the engagement teeth 26, symmetrical fixing grooves 33 are formed inside the collar 23. The fixing grooves 33 are slidably connected to the moving block 32 fixedly installed inside the moving sleeve 31. That is, the moving sleeve 31 on the outside of the connector body 1 and the moving sleeve 31 on the outside of the cable are moved to opposite positions so that they fit together. At the same time, a second sealing ring 34 is provided on the inner side of the moving sleeve 31. When the moving sleeve 31 fits, the second sealing ring 34 will be located inside the fitted moving sleeve 31, which can enhance the sealing of the connection of the moving sleeve 31. Secondly, through the outer end of the moving sleeve 31, etc. The mounting block 35 is installed at an angle, and the screw can be inserted into the mounting block 35 and tightened to further strengthen the connection between the connector body 1 and the cable. Secondly, the fixing block 36 is installed at an equal angle on the outside of the collar 23 set on the outside of the connector body 1. The connecting rod 37 is rotatably connected inside the fixing block 36. After the connector body 1 and the cable are connected, the other end of the connecting rod 37 can be rotated into the connecting block 38 set at an equal angle on the outside of the collar 23 installed on the outside of the cable. Then, the threaded rod 39 is inserted into the connecting block 38 and one end of the connecting rod 37 for tightening and limiting, which can also enhance the stability of the connection between the connector body 1 and the cable.

[0030] The working principle of this high-strength heat-shrinkable cable intermediate joint is as follows: a precision fixing mechanism 2 is symmetrically set on the outside of the joint body 1, and a precision fixing mechanism 2 is also set on the outside of the cable to be connected, which facilitates the quick and accurate connection and fixing of the joint body 1 and the cable. At the same time, a reinforcement mechanism 3 is set on the outside of the precision fixing mechanism 2, which can further enhance the stability of the connection between the joint body 1 and the cable.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
