The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figure 1 and Figure 2 As shown, a light-weight cable connector for ship use includes an insulating housing 1. There are two insulating housings 1 and they are symmetrically arranged front to back. A socket connector 5 and a plug connector 4 are respectively clamped on the opposite surfaces of the two insulating housings 1. A clamping mechanism 2 for locking the two insulating housings 1 is provided on the front insulating housing 1, and an auxiliary mechanism 3 for assisting the clamping mechanism 2 to perform locking is provided on the rear insulating housing 1.

[0030] like Figure 1 and Figure 2 As shown, the opposite surfaces of the two insulating shells 1 are connected with a cable body 6, the cable body 6 passing through the interior of the front insulating shell 1 is clamped with the socket connector 5, and the cable body 6 passing through the interior of the rear insulating shell 1 is clamped with the plug connector 4, and the opposite surfaces of the two insulating shells 1 are fixedly connected with a sealing gasket 7, the rear surface of the front sealing gasket 7 is provided with a groove, and the front surface of the rear sealing gasket 7 is provided with a protrusion, and the connection positions of the plug connector 4 and the socket connector 5 with the insulating shell 1 on the opposite back surfaces are both provided with a sealing gasket 2 8.

[0031] like Figure 1and Figure 2 As shown, the clamping mechanism 2 includes a clamping ring 21 mounted on the front insulating shell 1, and the front insulating shell 1 is provided with a clamping member 22 for connecting with the rear insulating shell 1. The clamping member 22 and the front insulating shell 1 are jointly provided with a limit member 23 for locking the plug connector 4 and the socket connector 5.

[0032] like Figure 2 、 Figure 3 and Figure 4 As shown, the clamping member 22 includes a mounting seat 221 fixedly connected to the outer circumferential surface of the insulating shell 1 and located in front of the limiting member 23. The top of the mounting seat 221 is hinged with a push bar 222, and 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. The rear surface of the push bar 222 is embedded with a limiting ball 224, and a connecting spring is arranged between the limiting ball 224 and the push bar 222.

[0033] like Figure 2 、 Figure 3 and Figure 4 As shown, auxiliary rollers are provided at the connection between the sliding adjustment seat 223 and the pushing bar 222. The auxiliary rollers change the sliding friction between the sliding adjustment seat 223 and the pushing bar 222 into rolling friction. The pushing bar 222 has a limited sliding groove corresponding to the auxiliary roller position. The top ends of the limiting rod 232 and the pushing rod 233 are jointly embedded in a hinged hinge rod. A through groove is provided at the position of the hinge rod corresponding to the upper surface of the sealing sheet 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. The rear end of the pushing bar 222 is provided with a groove 225.

[0034] During specific use, first pass the two cable bodies 6 through the two insulating shells 1 respectively, and then clamp the plug connector 4 and the socket connector 5 on one end of the two cable bodies 6 passing through the insulating shell 1 respectively. After the plug connector 4 and the socket connector 5 are respectively clamped in the corresponding insulating shell 1, the plug connector 4 and the socket connector 5 are plugged together, and then the clamping ring 21 is pushed to move backward on the front side of the insulating shell 1. At this time, as the clamping ring 21 continues to move, the inner circumferential surface of the clamping ring 21 gradually fits the surface of the push bar 222 and moves backward, so that the 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] like Figure 2 、 Figure 3 and Figure 4As shown, the limiting member 23 includes a plurality of mounting grooves 234 arranged in a circular array on the circumferential surface of the insulating shell 1, and a push rod 233 is slidably connected inside the mounting groove 234. The rear surface of the push rod 233 is fixedly connected to the limiting plug rod 232, and the top ends of the push rod 233 and the limiting plug rod 232 are jointly fixedly connected to a sealing sheet 231.

[0036] like Figure 2 、 Figure 3 and Figure 4 As shown, a limiting groove 9 adapted to the limiting rod 232 is provided at the front end of the plug connector 4 at the position corresponding to the limiting rod 232. The limiting rod 232 slides in cooperation with the limiting groove 9. The push rod 233 is made of conductive material. The top end of the outer surface of the push rod 233 is covered with insulating material (not shown in the figure), and the bottom end of the push rod 233 is exposed to the conductive material.

[0037] When the pressing ring 21 slides backward and gradually reduces the angle between the pushing bar 222 and the mounting seat 221, the pushing bar 222 cooperates with the hinged rod to push the pushing rod 233 to slide downward inside the mounting groove 234 through the sliding adjustment seat 223. In the process of pushing the pushing rod 233 to slide downward, the sliding adjustment seat 223 slides inside the limiting sliding groove on the pushing bar 222 to ensure that the pushing rod 233 slides smoothly into the interior of the mounting groove 234. When the slope at the bottom end of the pushing rod 233 is When it connects with the front end of the plug connector 4, the pushing rod 233 pushes the plug connector 4 to move a short distance away from the socket connector 5, and then as the pushing rod 233 continues to move downward, the limiting rod 232 is inserted into the limiting groove 9 on the plug connector 4 to ensure a stable connection between the plug connector 4 and the socket connector 5, and at the same time, the sealing sheet 231 is pressed against the inside of the mounting groove 234 to ensure the sealing between the pushing rod 233 and the mounting groove 234 and the mounting groove 234.

[0038] like Figure 1 and Figure 2 As shown, the auxiliary mechanism 3 includes a clamping part 31 arranged on the outer circumferential surface of the rear insulating shell 1, and a tightening ring 32 is fixedly connected on the outer circumferential surface of the rear insulating shell 1 and located behind the clamping part 31. An external thread groove is provided on the circumferential surface of the tightening ring 32. The inner diameter size of the front side of the tightening ring 21 is smaller than the inner diameter size of the rear side, and the inner circumferential surface of the rear side of the tightening ring 21 is provided with an internal thread groove that is compatible with the thread on the tightening ring 32.

[0039] like Figure 2 、 Figure 5 、 Figure 6 and Figure 7As shown, the clamping member 31 includes a guide groove 315 opened on the outer circumferential surface of the insulating shell 1 on the rear side, and the interior of the guide groove 315 is slidably connected to a sliding plate 314 along the front-to-back direction, and the front side of the upper surface of the sliding plate 314 is fixedly connected to a concave clamping block 311, and the rear side of the upper surface of the sliding plate 314 is fixedly connected to a positioning vertical plate 313, and the rear surface of the concave clamping block 311 is provided with a groove 2 316, and the groove 2 316 is slidably matched with the groove 1 225, and a through hole is opened on the front surface of the positioning vertical plate 313, and the size of the through hole is adapted to the size of the limiting ball 224 and is clamped together, and the top of the positioning vertical plate 313 is chamfered.

[0040] When in use, as the pressing collar 21 continues to move, the pressing collar 21 pushes the pressing member 22 to rotate on the mounting seat 221, and the pushing bar 222 is clamped in the recessed portion of the concave clamping block 311, and at the same time cooperates with the groove 1 225 on the pushing collar 222 and the groove 2 316 on the concave clamping block 311. When the groove 1 225 on the pushing collar 222 fits the groove 2 316 on the concave clamping block 311 and moves downward, the pushing bar 222 generates a forward thrust on the concave clamping block 311. Since the push rod 233 pushes the plug connector 4 to move a short distance to the outside of the socket connector 5, there is a gap between the two insulating shells 1 at this time, and the push bar 222 presses the two insulating shells 1 tightly, inserts the protrusion on the rear side sealing gasket 1 7 into the groove on the front side sealing gasket 1 7, and presses the sealing gasket 2 8 between the plug connector 4 and the socket connector 5 and the insulating shell 1. At this time, the connection position of the two insulating shells 1 is sealed. At the same time, the connection position between the cable body 6 and the insulating shell 1 is sealed.

[0041] When the locking cam 324 is in the unlock state, the locking cam 324 is in the unlock state, and the locking cam 326 is in the unlock state, so that the locking cam 326 can be unlocked.

[0042] Working principle: When in use, the staff first passes the two cable bodies 6 through the two insulating shells 1 respectively, and then respectively clamps them on the plug connector 4 and the socket connector 5, and then plugs the plug connector 4 and the socket connector 5 into the inside of the insulating shell 1. At this time, the plug connector 4 and the socket connector 5 are plugged together, and then the pressing ring 21 is pushed backward, and the pressing ring 21 cooperates with the pressing member 22 to push the limiter 23 to move into the inside of the insulating shell 1. At this time, the limiter 23 pushes the plug connector 4 to the outside of the socket connector 5 for a distance and then locks the plug connector 4 and the socket connector 5. At this time, the plug The head connector 4 and the socket connector 5 are in a conductive connection state, and the setting of the limit piece 23 makes the connection between the plug connector 4 and the socket connector 5 more stable. At this time, the clamping piece 22 is clamped together with the clamping piece 31 to ensure the clamping state between the two insulating shells 1, and then the clamping ring 21 is continued to be pushed to move. When the clamping ring 21 moves to the position of the tightening ring 32, the clamping ring 21 is screwed on the tightening ring 32 through the threaded cooperation of the internal and external thread grooves on the clamping ring 21 and the tightening ring 32, and the clamping force is applied again between the two insulating shells 1, and the connection position between the two insulating shells 1 is tightened again to ensure the sealing.
