Underwater cables are a vital infrastructure supporting global data exchange, carrying approximately 99% of the world's intercontinental communication traffic. They are the most important information carriers in modern international communication. Junction boxes play a crucial role in cable signal transmission systems. They are mainly used to protect wire connection points, prevent wires from being directly exposed to the outside, reduce the impact of external factors on wire connections, and thus reduce safety hazards such as short circuits and leakage.

However, the wiring steps of the above-mentioned cable junction box are cumbersome and inconvenient to use.

[0066] Further, with reference to the specific description of Figure 4 、 Figure 5 ,

[0067] The wiring box body 100 further comprises a sliding hole 1011, a sliding rod 1012, a first screw hole 1013, a hollow bolt 1014, a jacking rod 1015, a brake disc 1016, a positioning groove 1017, and a brake piece 1018. The sliding hole 1011 is evenly distributed and arranged on the side surface of the sedimentation groove 108 away from the sedimentation block 109. The sliding rod 1012 is evenly distributed and fixedly installed on the side surface of the sedimentation block 109 away from the electrode one 1010, and is in sliding connection with the inner wall of the sliding hole 1011. The first screw hole 1013 is evenly distributed and arranged on the side surface of the rotating column 104 away from the sedimentation groove 108, and the position corresponds to the sliding hole 1011 one by one. The hollow bolt 1014 is threadedly screwed in the first screw hole 1013.

[0068] Specifically, the end of the plurality of electrodes one 1010 coincides with the end of the plurality of electrodes two 205, then the end plug 201 is continuously inserted into the socket 102 until the tapered protrusion of the electrode one 1010 is inserted into the tapered groove of the electrode two 205, and then the electrode one 1010 and the sinker 109 are pushed to slide into the sink groove 108, and the four slide rods 1012, the four jacks 1015, the brake disc 1016 and the plurality of brake pads 1018 slide together, at the same time, the spring 1020 is compressed and stored, when the end plug 201 is inserted into place, the surface of the brake pad 1018 just touches the inner wall of the socket 102, so that the static friction between the surface of the brake pad 1018 and the inner wall of the socket 102 prevents the rotating column 104 from rotating easily, ensuring the stability of the cable connection.

[0069] Further, with reference to Figure 2 、 Figure 8 ,

[0070] The wire insertion body 200 further comprises a locking sleeve 206, a wire tooth 207, a ratchet 208, a rectangular groove 2010, a bite block 2011, a torsion ring 2012, a ring groove 2013 and an L-shaped torsion block 2014. The locking sleeve 206 is rotatably installed on the outer wall of the end plug 201. The wire tooth 207 is formed on the outer wall of the locking sleeve 206. The ratchet 208 is formed on the outer wall of the end plug 201. The rectangular groove 2010 is formed through the outer wall of the locking sleeve 206, and there are two of them. The two rectangular grooves 2010 are diagonally distributed about the center of the locking sleeve 206. The torsion ring 2012 is rotatably installed on the outer wall of the locking sleeve 206 and located outside the two rectangular grooves 2010. The ring groove 2013 is formed on the inner wall of the torsion ring 2012 and located outside the two rectangular grooves 2010. The L-shaped torsion block 2014 is fixedly installed on the inner wall of the ring groove 2013, and there are two of them. The two L-shaped torsion blocks 2014 are respectively located inside the two rectangular grooves 2010. The L-shaped torsion block 2014 is straightly bent. The bite block 2011 is integrally formed on the inner wall of the side of the rectangular groove 2010 close to the bent end of the L-shaped torsion block 2014. The end of the bite block 2011 is matched with the ratchet 208, and the bite block 2011 engages with the ratchet 208.

[0071] The wire box body 100 further comprises a wire hole two 1019. The wire hole two 1019 is formed on the inner wall of the socket 102 close to one end of the wire insertion body 200. The wire hole two 1019 is threadedly connected with the wire tooth 207. The wire hole two 1019 is fixedly provided with a sealing ring 300 inside. The sealing ring 300 is used for sealing and waterproofing between the wire box body 100 and the wire insertion body 200.

[0072] Specifically, during the process of inserting the end plug 201 into the socket 102, the torsion ring 2012 is rotated clockwise, which drives the two L-shaped torsion blocks 2014 to rotate together. During this process, the side surface of the L-shaped torsion block 2014 is in contact with the inner wall of the side of the rectangular groove 2010 away from the engaging block 2011, thus driving the locking sleeve 206 to rotate together. The rotation of the locking sleeve 206 drives the opened thread 207 to rotate, so that the thread 207 is fixed in the socket 102 under the action of the thread force of the second silk hole 1019. During this process, the engaging block 2011 rotates together with the locking sleeve 206. Due to the engagement of the engaging block 2011 at the end and the ratchet 208, the locking sleeve 206 cannot rotate counterclockwise, thereby ensuring the stability of the cable communication signal transmission. When it is necessary to separate the plug-in main body 200 from the wire box main body 100, the torsion ring 2012 can be directly rotated counterclockwise, which drives the L-shaped torsion block 2014 to rotate towards the direction close to the engaging block 2011, causing the end of the bent end of the L-shaped torsion block 2014 to be in contact with the surface of the engaging block 2011. Under the action of the wedge force, the engaging block 2011 is pushed away from the ratchet 208, and the engaging block 2011 is elastically deformed, thereby disengaging the ratchet 208. Then, the torque transmitted by the L-shaped torsion block 2014 to the engaging block 2011 is transmitted to the locking sleeve 206 through the engaging block 2011, thereby driving the thread 207 to rotate counterclockwise along the inside of the second silk hole 1019, and the plug-in main body 200 is withdrawn from the socket 102. It is convenient to assemble and disassemble, and is suitable for use in complex environments.

[0073] The underwater ship communication cable sealing pressure terminal box in the scheme is used for connecting the cable. When the terminal is connected, first, the end plug 201 is aligned with the end of the socket 102, and the end plug 201 is slowly inserted into the socket 102. During this period, the end of the rotating column 104 slowly enters the inner cavity of the end of the end plug 201, and further under the magnetic force between the plurality of magnets N two 203, the plurality of magnets S two 204, the plurality of magnets S one 106 and the plurality of magnets N one 107, the rotating column 104 is driven to rotate by a certain angle, the plurality of magnets S one 106 is rotated to the side close to the plurality of magnets N two 203, and the plurality of magnets N one 107 is rotated to the side of the plurality of magnets S two 204. At this time, under the action of magnetic attraction, the rotating column 104 will not continue to rotate, and the rotating column 104 rotates to drive the sedimentation block 109 and the plurality of electrodes one 1010 to rotate together. It should be noted that after the plurality of magnets S one 106 is rotated to the side close to the plurality of magnets N two 203, and the plurality of magnets N one 107 is rotated to the side of the plurality of magnets S two 204, the end of the plurality of electrodes one 1010 coincides with the position of the end of the plurality of electrodes two 205. Subsequently, the end plug 201 is continuously inserted into the socket 102 until the tapered protrusion at the end of the electrode one 1010 is inserted into the tapered groove at the end of the electrode two 205. With the continuous insertion of the end plug 201, the electrode one 1010 and the sedimentation block 109 are pushed to slide into the inside of the sedimentation groove 108, and the four slide rods 1012, the four jacks 1015, the brake disc 1016 and the plurality of brake pads 1018 are driven to slide together. At the same time, the spring 1020 is compressed and stored. When the end plug 201 is inserted in place, the surface of the plurality of brake pads 1018 just abuts against the inner wall of the socket 102, so that under the action of the static friction between the surface of the brake pad 1018 and the inner wall of the socket 102, the rotating column 104 as a whole will not easily rotate, ensuring the stability of the cable connection.
