Description

Technical Field

[0001] The invention relates to the technical field of cable installation, in particular to a highly sealed marine cable butt joint. Background Art

[0002] With the accelerated development of globalization, the demand for international communications is increasing. In order to meet this demand, a large number of submarine cable systems have been laid on the bottom of the world's oceans. These submarine cable systems are an important part of modern Internet infrastructure and are responsible for carrying most of the world's Internet data traffic and telephone communications.

[0003] The marine cable connectors currently used on the market usually adopt a design that directly contacts seawater, that is, the metal contact heads of the cable are exposed to seawater. Although this design simplifies the installation process, since the metal contact heads of the cable are immersed in seawater, seawater is likely to remain on the metal contact heads of the cable after the connection is completed. After the metal contact heads are immersed in these residual seawater for a long time, they are easily corroded by salt, minerals and other chemicals, resulting in oxidation or formation of a corrosion layer on the surface of the contact heads, which will not only affect the quality of signal transmission, but also reduce the service life of the cable. In severe cases, it may even affect the electrical performance and may cause problems such as short circuits. Summary of the Invention

[0004] In view of this, the present invention provides a highly sealed marine cable connector, which can solve the shortcomings of existing marine cable connectors in that seawater is easily retained on the metal contacts of the cables after the connection is completed, and the metal contacts are easily corroded after being soaked in this residual seawater for a long time.

[0005] The technical implementation scheme of the present invention is: a highly sealed marine cable connector, including cable I and cable II, and also including a docking joint I, a docking joint II, a rotating ball, a rotating block, a contact head I, a guide rod, a contact head II, a spring, a rotating mechanism, a sealing mechanism and a fixing mechanism, the docking joint I is connected to cable I, the docking joint II is connected to cable II, the rotating ball is rotatably installed in the docking joint I, the rotating block is rotatably installed in the docking joint II, the contact head I is installed in the rotating ball, the guide rod is installed in the rotating block, the contact head II is slidably set on the guide rod, the two ends of the spring are respectively connected to the guide rod and the contact head II, the rotating mechanism is used to drive the rotating ball and the rotating block to rotate, the sealing mechanism is used to seal the interior of the docking joint I and the docking joint II, and the fixing mechanism is used to fix the docking joint I and the docking joint II.

[0029] See Figure 3 and Figure 4As shown, the rotating mechanism includes a connecting rod 11, a knob 12 and an indicator 13; the connecting rod 11 is rotatably provided on the docking joint I3 and the docking joint II4, the bottom end of the connecting rod 11 on the docking joint I3 is connected to the rotating ball 5, and the bottom end of the connecting rod 11 on the docking joint II4 is connected to the rotating block 6; the knob 12 is installed on the top of the connecting rod 11; the indicator 13 is set in the middle of the top of the knob 12, and the indicator 13 is arrow-shaped.

[0030] See Figure 6 As shown, the sealing mechanism includes a sealing ring I14, a sealing ring II15, a sealing strip I16 and a sealing strip II17; two sealing rings I14 are provided on the upper side of the interior of the butt joint I3, and the inner sides of the two sealing rings I14 are in close contact with the outer wall of the connecting rod 11 in the butt joint I3, and the sealing ring I14 is used to seal the inner wall of the butt joint I3 and the outer wall of the connecting rod 11, thereby preventing seawater from seeping in from between the inner wall of the butt joint I3 and the outer wall of the connecting rod 11; two sealing rings II15 are provided on the upper side of the interior of the butt joint II4, and the inner sides of the two sealing rings II15 are in close contact with the outer wall of the connecting rod 11 in the butt joint II4, thereby sealing the inner wall of the butt joint II4 and the outer wall of the connecting rod 11 The sealing is performed to prevent seawater from seeping in from between the inner wall of the butt joint Ⅱ4 and the outer wall of the connecting rod 11; a sealing strip Ⅰ16 is installed on the right side of the inside of the butt joint Ⅰ3, and the inner side of the sealing strip Ⅰ16 is in close contact with the outer wall of the rotating ball 5. The sealing strip Ⅰ16 is used to seal the inner wall of the butt joint Ⅰ3 and the outer wall of the rotating ball 5, which can prevent seawater from seeping in from between the inner wall of the butt joint Ⅰ3 and the outer wall of the rotating ball 5; a sealing strip Ⅱ17 is installed on the left side of the inside of the butt joint Ⅱ4, and the inner side of the sealing strip Ⅱ17 is in close contact with the outer wall of the rotating block 6. The sealing strip Ⅱ17 is used to seal the inner wall of the butt joint Ⅱ4 and the outer wall of the rotating block 6, which can prevent seawater from seeping in from between the inner wall of the butt joint Ⅱ4 and the outer wall of the rotating block 6.

[0031] See Figure 7 and Figure 8 As shown, the fixing mechanism includes a threaded ring 18, a rubber strip I19, a rubber strip II20 and a rubber strip III21; the threaded ring 18 is threadedly installed on the left outer side of the docking joint II4, and threaded grooves are opened on the inner side of the threaded ring 18, the right outer side of the docking joint I3 and the left outer side of the docking joint II4; the rubber strip I19 is installed in the threaded groove of the docking joint I3; the rubber strip II20 is installed in the threaded groove of the docking joint II4; the rubber strip III21 is installed in the threaded groove on the inner side of the threaded ring 18.

[0032] In the initial state, the contact head II9 in the rotating block 6 contacts the inner wall of the docking joint II4. Since the inner wall of the docking joint II4 squeezes the contact head II9, the contact head II9 retracts into the rotating block 6 and the spring 10 is in a compressed state. When in use, dock the docking joint I3 and the docking joint II4, then twist the threaded ring 18 to rotate it so that the threaded ring 18 moves between the docking joint I3 and the docking joint II4, thereby fixing the docking joint I3 and the docking joint II4 with the threaded ring 18, and contacting the rubber strip III21 on the threaded ring 18 with the docking joint I3 and the docking joint II4, and the rubber strips I19 and II20 on the docking joint I3 and the docking joint II4 with the threaded ring 18, and the rubber strips I19, II20 and III21 can be used to seal the threaded ring 18 and the docking joint I3 and the docking joint II4, thereby preventing seawater from seeping in through the gap between the threaded ring 18 and the docking joint I3 and the docking joint II4. After the docking of the docking joint I3 and the docking joint II4 is completed, twist the left and right sides. The knob 12 is rotated together, thereby driving the indicator 13, the connecting rod 11, the rotating ball 5 and the rotating block 6 to rotate, and then driving the contact head I7 and the contact head II9 to rotate until the arrows of the two indicator marks 13 point to each other. In this way, the contact head I7 and the contact head II9 are aligned. When the contact head I7 and the contact head II9 are in the aligned state, the contact head II9 will be separated from the inner wall of the docking head II4. At this time, under the elastic force of the spring 10, the spring 10 drives the contact head II9 to extend from the rotating block 6, so that the contact head II9 contacts the contact head I7. In this way, the cable I1 and the cable II2 can be docked, and the elastic force of the spring 10 can be used to make the spring 10 apply pressure to squeeze the contact head II9, so that the contact head II9 is ​​close to the contact head I7 (such as Figure 5 As shown), thereby avoiding poor contact between contact head II9 and contact head I7.

[0033] See Figure 3-Figure 5 As shown, a fluff cloth 22 is also included; the rotating ball 5 is symmetrically connected to the fluff cloth 22, and the fluff cloth 22 is used to process the liquid remaining between the docking joint I3 and the docking joint II4.

[0034] In the initial state, the pile cloth 22 is squeezed and contracted in the rotating ball 5 by the inner wall of the docking joint I 3; After the docking of the docking joint I3 and the docking joint II4 is completed, the left knob 12 can be twisted and rotated first, so that the left knob 12 drives the indicator mark 13, the connecting rod 11 and the rotating ball 5 on the left to rotate, thereby driving the contact head I7 and the fluffy cloth 22 to rotate, until the fluffy cloth 22 rotates to the position where the docking joint I3 and the docking joint II4 are docked (the fluffy cloth 22 on both the front and rear sides can be used. After the fluffy cloth 22 on one side is used, the fluffy cloth 22 on the other side will be used next time). When the fluffy cloth 22 rotates to the position where the docking joint I3 and the docking joint II4 are docked, the inner wall of the docking joint I3 will lose the squeeze on the fluffy cloth 22. At this time, the fluffy cloth 22 will fill the docking joint I through natural fluffing. 3 and the gap between the butt joint Ⅱ4, so that the residual seawater between the butt joint Ⅰ3 and the butt joint Ⅱ4 is adhered by the fluffy cloth 22, and then the residual seawater between the butt joint Ⅰ3 and the butt joint Ⅱ4 is processed to prevent the residual seawater between the butt joint Ⅰ3 and the butt joint Ⅱ4 from affecting the subsequent docking of the contact head Ⅰ7 and the contact head Ⅱ9; when the residual seawater between the butt joint Ⅰ3 and the butt joint Ⅱ4 is processed, twist the left and right knobs 12 to rotate together, and when the left knob 12 drives the left indicator 13, the connecting rod 11, the rotating ball 5, the contact head Ⅰ7 and the fluffy cloth 22 to rotate again, the fluffy cloth 22 will be squeezed by the inner wall of the butt joint Ⅰ3 and shrink again in the rotating ball 5.

[0035] See Figure 9 and Figure 10 As shown, a protective mechanism is also included, which includes a protective shell I 23, a protective shell II 24, a sealing strip III 25, a fixing ring 26 and a rubber ring 27; the protective shell II 24 is rotatably arranged on the protective shell I 23, and the protective shell I 23 and the protective shell II 24 are used to wrap the docking joint I 3 and the docking joint II 4, and arc-shaped grooves are provided on the left and right sides of the protective shell I 23 and the left and right sides of the protective shell II 24; the sealing strip III 25 is connected to the inner side of the protective shell II 24 at intervals, and the sealing strip III 25 is in contact with the protective shell I 23. The sealing strip III 25 is used to seal the protective shell I 23 and the protective shell II 24, which can prevent small particles in the ocean from penetrating from the protective shell I 23 and the protective shell II 24; fixing rings 26 are placed between the left and right sides of the protective shell I 23 and the protective shell II 24; the rubber ring 27 is arranged on the inner side of the fixing ring 26, and the rubber ring 27 is stuck in the arc-shaped grooves of the protective shell I 23 and the protective shell II 24.

[0036] After the cable I1 and the cable II2 are connected, the protective shell I23 and the protective shell II24 can be used to wrap the joint I3 and the joint II4 by closing, so as to protect the joint I3 and the joint II4 and thus prolong the service life of the joint I3 and the joint II4; then the two fixing rings 26 are squeezed into the left and right sides between the protective shell I23 and the protective shell II24 respectively, so that the fixing rings 26 fix the protective shell I23 and the protective shell II24, thereby maintaining the closed state of the protective shell I23 and the protective shell II24. When the rubber ring 27 in the fixing ring 26 contacts the protective shell I23 and the protective shell II24, the protective shell I23 and the protective shell II24 will squeeze the rubber ring 27 to deform. When the rubber ring 27 in the fixing ring 26 is aligned with the arc groove on the protective shell I23 and the protective shell II24, the rubber ring 27 will return to its original shape and be stuck in the arc groove of the protective shell I23 and the protective shell II24 (such as Figure 9 As shown), the fixing ring 26 is limited; if the protective shell I 23 and the protective shell II 24 need to be removed later, the two fixing rings 26 are pulled out from between the protective shell I 23 and the protective shell II 24 to the left and right sides respectively, so that the two fixing rings 26 are separated from between the protective shell I 23 and the protective shell II 24, and then the protective shell I 23 and the protective shell II 24 can be opened, and then the protective shell I 23 and the protective shell II 24 can be removed.

[0037] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed by the present invention, which should be covered by the scope of protection of the present invention.
