[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1-3 As shown, a sealed and fastened cable joint includes an intermediate insulating seat 1, a cable joint assembly 7, and a sealing and fastening assembly 8. A butt joint 2 is fixed to both sides of the intermediate insulating seat 1, and the middle of the intermediate insulating seat 1 has a hollow structure. An insulating mounting cylinder 3 is provided on the outer side of the butt joint 2, and the insulating mounting cylinder 3 is fixedly connected to the intermediate insulating seat 1. Connecting grooves 4 are provided on both the left and right outer sides of the intermediate insulating seat 1, and the connecting grooves 4 have annular structures. The butt joint 2 and the insulating mounting cylinder 3 have concentric circular structures, and a gasket 5 is provided between the butt joint 2 and the insulating mounting cylinder 3. A liquid-retaining air bladder layer 6 is adhered to the inner wall of the insulating mounting cylinder 3, and the liquid-retaining air bladder layer 6 has an annular structure. The cable joint assembly 7 is installed on one side of the butt joint 2, and the cable... The connector assembly 7 includes a cable plug tube 701 and a connector body 702. The connector body 702 is integrally fixed to the side of the cable plug tube 701 near the connector 2. The inner side of the connector body 702 is provided with an internal thread, and the outer side of the connector 2 is provided with an external thread. The connector 2 and the connector body 702 are screwed together. The two connectors 2 on both sides of the intermediate insulating seat 1 can be connected to the cable connector assemblies 7 on the left and right sides. The connector 2 can be screwed together with the connector body 702. The connection method is relatively convenient. The gasket 5 can provide good sealing performance. The cable plug tube 701 can serve as a cable channel, allowing the cable to be installed inside. The insulating mounting cylinder 3 outside the connector 2 can provide protection.

[0024] like Figure 1 , Figures 3-4As shown, a sealing and fastening assembly 8 is installed on the outer side of the connector body 702. The sealing and fastening assembly 8 includes a protrusion 801, an outer shield 802, and a snap-fit ​​connector 803. A ring of protrusions 801 is fixed to the outer side of the top of the connector body 702, and an outer shield 802 is fixed to the outer side of the middle part of the connector body 702. The snap-fit ​​connector 803 is integrally fixed to the front end of the outer shield 802. The cross-section of the outer shield 802 is L-shaped, and the size of the cavity between the outer shield 802 and the connector body 702 matches the size of the insulating mounting cylinder 3. The snap-fit ​​connector 803 is engaged with the connecting groove 4. The snap-fit ​​connector 803, the outer shield 802, and the connector body 702 are all connected together. 2. It has a concentric circle structure. During the connection process between the connector body 702 and the mating connector 2, the protrusion 801 on the outer side of the top of the connector body 702 can pierce the liquid storage bladder layer 6 on the inner wall of the insulating mounting cylinder 3 when rotating and docking. This allows the adhesive inside the liquid storage bladder layer 6 to overflow and fill the gap between the connector body 702, the mating connector 2, and the insulating mounting cylinder 3. After the adhesive has fully cured, the entire cable connector can be tightened and sealed. Furthermore, the snap-fit ​​connector 803 of the outer shield 802 can be snapped into the connecting grooves 4 on both sides of the intermediate insulating seat 1 to further seal and protect the connection. The outer shield 802 and the insulating mounting cylinder 3 can enhance the structural strength of the connector.

In use, the two mating connectors 2 on either side of the central insulating base 1 are first connected to the cable connector assemblies 7 on the left and right sides. The threaded connection method is convenient. During the connection process between the connector body 702 and the mating connector 2, the protrusion 801 on the outer side of the top of the connector body 702 can pierce the liquid-filled gas bladder layer 6 inside the insulating mounting cylinder 3 during rotational connection, allowing the adhesive inside the liquid-filled gas bladder layer 6 to overflow and fill the connector body 702 and the mating connector 2, as well as the insulating mounting cylinder 3. After the adhesive fully cures, the gap between the sleeves 3 will allow the entire cable joint to be tightened and sealed. At the same time, the snap-fit ​​connectors 803 of the outer shield 802 can be snapped into the connecting grooves 4 on both sides of the intermediate insulation seat 1, further sealing and protecting the external connection. The gasket 5 between the connector 2 and the connector body 702 provides good sealing performance, and the insulating mounting sleeves 3 outside the connector 2 provide protection. Furthermore, the outer shield 802 and the insulating mounting sleeves 3 enhance the structural strength of the joint. This completes the process of using the sealed and tightened cable joint.
