Description

Technical Field

[0001] The present invention relates to the technical field of cable joints, and particularly to a marine light cable and its joint. Background Art

[0002] A cable butt joint, also known as a cable connector or a cable joint, is a device used to connect the conductor ends of two cables to ensure the reliable transmission of current, signals or data. It is widely used in various fields such as power systems, communication networks, and industrial equipment. Among them, the marine cable butt joint belongs to one of them.

[0003] When the cable butt joint is used on a ship, during the navigation of the ship, the hull itself will often jolt.

Detailed implementation manners

[0028] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] As Figure 1 and Figure 2 shown, a marine light cable joint includes an insulating housing 1. The number of the insulating housings 1 is two and they are symmetrically arranged front and back. A socket connector 5 and a plug connector 4 are respectively clamped on the opposite surfaces of the two insulating housings 1. A pressing mechanism 2 for locking the two insulating housings 1 is arranged on the front insulating housing 1, and an auxiliary mechanism 3 for assisting the pressing mechanism 2 to lock is arranged on the rear insulating housing 1.

[0030] As Figure 1 and Figure 2 shown, the cable bodies 6 penetrate through and are connected to the opposite surfaces of the two insulating housings 1. The cable body 6 penetrating through the interior of the front insulating housing 1 is clamped with the socket connector 5, and the cable body 6 penetrating through to the interior of the rear insulating housing 1 is clamped with the plug connector 4. First sealing gaskets 7 are fixedly connected to the opposite surfaces of the two insulating housings 1. A groove is formed on the rear surface of the first sealing gasket 7 on the front side, and a protrusion is arranged on the front surface of the first sealing gasket 7 on the rear side. Second sealing gaskets 8 are arranged at the connection positions of the opposite surfaces of the plug connector 4 and the socket connector 5 with the insulating housing 1.

[0031] As Figure 1and Figure 2 As shown in Figure 2 , the pressing mechanism 2 includes a pressing collar 21 sleeved on the front insulating housing 1. A pressing member 22 for connecting with the rear insulating housing 1 is arranged on the front insulating housing 1. A limiting member 23 for locking the plug connector 4 and the socket connector 5 is jointly arranged on the pressing member 22 and the front insulating housing 1.

[0032] As Figure 2 、 Figure 3 and Figure 4 As shown in Figure 2 , Figure 3 and Figure 4 , the pressing member 22 includes a mounting seat 221 fixedly connected to the outer circumferential surface of the insulating housing 1 and located in front of the limiting member 23. A push bar 222 is hinged to the top end of the mounting seat 221. A torsion spring is arranged between the push bar 222 and the mounting seat 221. A sliding adjustment seat 223 is slidably connected to the push bar 222. A limiting ball 224 is embedded and connected to the rear surface of the push bar 222. A connecting spring is arranged between the limiting ball 224 and the push bar 222.

[0033] As Figure 2 、 Figure 3 and Figure 4 As shown in Figure 2 , Figure 3 and Figure 4 , auxiliary rollers are arranged at the connection positions between the sliding adjustment seat 223 and the push bar 222, which change the sliding friction between the sliding adjustment seat 223 and the push bar 222 into rolling friction. Limiting chutes are respectively opened at the positions of the push bar 222 corresponding to the auxiliary rollers. The top ends of the limiting insertion rod 232 and the push rod 233 are jointly embedded and hinged with a hinge rod. A through groove is opened at the position corresponding to the hinge rod on the upper surface of the sealing piece 231. The top end of the hinge rod passes through the through groove and is hinged to the lower surface of the sliding adjustment seat 223. A bevel 225 is arranged at the rear end of the push bar 222.

[0034] During specific use, first, the two cable bodies 6 are respectively passed through the two insulating housings 1. Then, the plug connector 4 and the socket connector 5 are respectively clamped on one end of the two cable bodies 6 passing through the insulating housings 1. After the plug connector 4 and the socket connector 5 are respectively clamped inside the corresponding insulating housings 1, at this time, the plug connector 4 and the socket connector 5 are plugged together. Then, the pressing collar 21 is pushed to move backward on the front insulating housing 1. At this time, as the pressing collar 21 continuously moves, the inner circumferential surface of the pressing collar 21 gradually fits against the surface of the push bar 222 and moves backward, so that the included angle between the push bar 222 and the mounting seat 221 gradually decreases, and at the same time, the torsion spring between the push bar 222 and the mounting seat 221 is contracted.

[0035] As Figure 2 、 Figure 3 and Figure 4As shown, the limiting member 23 includes a plurality of mounting grooves 234 formed in a circumferential array on the circumferential surface of the insulating housing 1. A push rod 233 is slidably connected inside the mounting groove 234. A limiting insertion rod 232 is fixedly connected to the rear surface of the push rod 233. A sealing piece 231 is fixedly connected to the top ends of the push rod 233 and the limiting insertion rod 232 together.

[0036] As Figure 2 、 Figure 3 and Figure 4 shown, limiting grooves 9 adapted to the limiting insertion rods 232 are respectively formed at the front ends of the plug connectors 4 at positions corresponding to the limiting insertion rods 232. The limiting insertion rods 232 are in sliding fit with the limiting grooves 9. The push rod 233 is made of a conductive material. The top end of the outer surface of the push rod 233 is coated with an insulating material (not shown in the figure). The bottom end of the push rod 233 is in a state where the conductive material is exposed.

[0037] During specific use, when the pressing collar 21 slides backward and gradually reduces the angle between the push bar 222 and the mounting seat 221, at this time, the push bar 222 drives the push rod 233 to slide downward inside the mounting groove 234 through the sliding adjustment seat 223 and the hinge rod. During the process of pushing the push rod 233 to slide downward, the sliding adjustment seat 223 slides inside the limiting chute on the push bar 222 to ensure that the push rod 233 smoothly slides into the mounting groove 234. When the slope at the bottom end of the push rod 233 contacts the front end of the plug connector 4, at this time, the push rod 233 pushes the plug connector 4 to move a short distance away from the socket connector 5. Then, as the push rod 233 continues to move downward, the limiting insertion rod 232 is inserted into the limiting groove 9 on the plug connector 4 to ensure the stable connection between the plug connector 4 and the socket connector 5. At the same time, the sealing piece 231 is pressed tightly inside the mounting groove 234 to ensure the sealing between the push rod 233 and the mounting groove 234 and the mounting groove 234.

[0038] As Figure 1 and Figure 2 shown, the auxiliary mechanism 3 includes a clamping member 31 arranged on the outer circumferential surface of the rear insulating housing 1. A tensioning ring 32 is fixedly connected to the outer circumferential surface of the rear insulating housing 1 and located behind the clamping member 31. An external thread groove is arranged on the circumferential surface of the tensioning ring 32. The inner diameter dimension of the front side of the pressing collar 21 is smaller than that of the rear side. An internal thread groove adapted to the thread on the tensioning ring 32 is arranged on the inner circumferential surface of the rear side of the pressing collar 21.

[0039] As Figure 2 、 Figure 5 、 Figure 6 and Figure 7As shown in the figure, the snap-in part 31 includes a guiding chute 315 formed on the outer circumferential surface of the rear side of the insulating housing 1. A sliding plate 314 is slidably connected in the guiding chute 315 in the front-rear direction. A concave snap-in block 311 is fixedly connected to the front side of the upper surface of the sliding plate 314. A positioning vertical plate 313 is fixedly connected to the rear side of the upper surface of the sliding plate 314. A second bevel 316 is provided on the rear surface of the concave snap-in block 311. The second bevel 316 is slidably engaged with the first bevel 225. A through hole is formed in the front surface of the positioning vertical plate 313. The size of the through hole is adapted to and snap-fitted with the size of the limiting ball 224. The top end of the positioning vertical plate 313 is provided with a chamfer.

[0040] During specific use, as the pressing collar 21 continues to move, when the pressing member 22 is pushed by the pressing collar 21 to rotate on the mounting seat 221, the pushing bar 222 is snapped into the notch inside the concave snap-in block 311. At the same time, in cooperation with the first bevel 225 on the pushing bar 222 and the second bevel 316 on the concave snap-in block 311, when the first bevel 225 on the pushing bar 222 fits on the second bevel 316 on the concave snap-in block 311 and then moves downward, at this time, the pushing bar 222 generates a forward thrust on the concave snap-in block 311. Since the pushing rod 233 pushes the plug connector 4 to move a short distance outward from the socket connector 5, there is a gap between the two insulating housings 1 at this time. The pushing bar 222 presses the two insulating housings 1 together, inserts the protrusion on the rear sealing gasket 7 into the groove inside the front sealing gasket 7, and presses the sealing gasket 8 between the plug connector 4 and the socket connector 5 and the insulating housing 1. At this time, the connection position of the two insulating housings 1 is sealed. At the same time, the connection position between the cable body 6 and the insulating housing 1 is sealed.

[0041] As the pressing collar 21 continues to move, when the limiting ball 224 on the pushing bar 222 is snapped into the through hole on the positioning vertical plate 313, the rear end of the pressing collar 21 moves to the front end of the tensioning ring 32 at this time. Then, the pressing collar 21 is rotated. The internal thread groove on the pressing collar 21 is threadedly engaged with the external thread groove on the tensioning ring 32. By continuously rotating the pressing collar 21, the inner diameter of the small diameter of the pressing collar 21 fits on the front surface of the concave snap-in block 311 and drives the concave snap-in block 311 to move backward. At this time, the concave snap-in block 311 cooperates with the sliding plate 314 to slide backward in the guiding chute 315. At the same time, the concave snap-in block 311 drives the pushing bar 222 to move backward synchronously, applying a secondary pressing force between the two pressed insulating housings 1 to further ensure the sealing performance of the connection between the two insulating housings 1.

[0042] Working principle: During specific use, first, the staff passes two cable bodies 6 through two insulating shells 1 respectively, then clamps them onto the plug connector 4 and the socket connector 5 respectively, and then inserts the plug connector 4 and the socket connector 5 inside the insulating shell 1. At this time, the plug connector 4 and the socket connector 5 are inserted together. Then, by pushing the pressing collar 21 backward, the pressing collar 21 cooperates with the pressing member 22 to push the limiting member 23 into the insulating shell 1. At this time, the limiting member 23 pushes the plug connector 4 outwards a certain distance from the socket connector 5 and then locks the plug connector 4 and the socket connector 5. At this time, the plug connector 4 and the socket connector 5 are in a conductive connection state. The setting of the limiting member 23 makes the connection between the plug connector 4 and the socket connector 5 more stable. At this time, the pressing member 22 is clamped with the clamping member 31 to ensure the pressing state between the two insulating shells 1. Then, continue to push the pressing collar 21 to move. When the pressing collar 21 moves to the tensioning ring 32 position, through the thread fit of the internal and external thread grooves on the pressing collar 21 and the tensioning ring 32, the pressing collar 21 is screwed onto the tensioning ring 32 to apply a pressing force to the two insulating shells 1 again, and the connection position between the two insulating shells 1 is pressed again to ensure the sealing performance.
