With the above technical solution, the driving portion 5 rotates axially relative to the plug 1 and the insertion portion 4, and drives the third sliding pin 72 to move along the fourth sliding groove 103 and enter the third sliding groove 102, and simultaneously drives the fourth sliding pin 73 to move along the fifth sliding groove 701; the driving part 5 drives the inserting part 4 to move synchronously along the axial direction of the plug 1, and drives the third sliding pin 72 to move along the third sliding groove 102.

In a preferred embodiment shown in fig. 3, in order to realize the re-locking of the driving part 5 and the main body 11 after the driving part 5 rotates for the second time, an arc-shaped sixth sliding groove 104 is further formed on the outer wall of the main body 11 located in the housing 12 along the outer contour of the radial section of the main body, one end of the sixth sliding groove 104 is communicated with the end of the third sliding groove 102 facing the socket 2, the other end of the sixth sliding groove is closed, and the sixth sliding groove 104 and the fourth sliding groove 103 are disposed on two axial sides of the third sliding groove 102; after the insertion portion 4 is inserted into the socket 2 and optical fiber signal connection is achieved, the driving portion 5 rotates axially relative to the plug 1 and the insertion portion 4, and drives the fourth sliding pin 73 to move along the fifth sliding groove 701, and simultaneously drives the third sliding pin 72 to enter the sixth sliding groove 104 from the third sliding groove 102 and move along the sixth sliding groove 104.

In a preferred embodiment shown in fig. 5, during the "two-in-two-out" operation of the driving portion 5, the mating portion of the plug 1 and the socket 2 is engaged by a wedge, so that the main body 11 of the plug 1 and the socket 2 remain relatively stationary.

Referring to fig. 1, in combination with fig. 2, the application method of the photoelectric composite underwater wet plug connector of the present invention adopts the photoelectric composite underwater wet plug connector of any one of the above embodiments, and includes the following steps.

In the first step, the first insertion is performed, and the purpose of the first insertion is to insert the socket 2 into the cartridge 61 and abut against the plug 1 to realize electrical signal connection, and in this process, it is observed that the first sliding pin 63 and the second sliding pin 64 enter the first sliding slot 601 at the same time. At this time, the third slide pin 72 on the driving portion 5 is abutted in the fourth slide groove 103 and the fourth slide pin 73 is abutted in the fifth slide groove 701 of the ring body 71 in the housing 12, so that the driving portion 5 is fixed to the entire plug 1 and the insertion portion 4.

Step two, performing a first rotation operation, namely rotating the driving part 5 and driving the shell 12 and the cylinder shell 61 to synchronously rotate relative to the main body part 11, wherein the purpose of the operation is to enable the sealing assembly 3 to release the sealing state of the plug 1 and the socket 2; specifically, the driving part 5 drives the housing 12 and the shell 61 to rotate the gear ring 33, in this process, it is observed that the second sliding pin 64 enters the second sliding groove 602, and because the first sliding pin 63 cannot enter the second sliding groove 602 and the first sliding pin 63 is fixedly arranged on the shell 62, the rotation of the shell 61 drives the first sliding pin 63 to abut against the first sliding groove 601 and push the shell 62 to synchronously rotate with the shell 61, so that the two gear rings 33 in the plug 1 and the socket 2 synchronously rotate, and the gear 32 drives the sealing element 31 to rotate, so that the axial direction of the through hole 301 is converted from an included angle to overlap relative to the axial direction of the cavity 101, and the through hole 301 inside the plug 1 and the socket 2 is communicated with each other through the two sealing elements 31. At the same time, in the interior of the housing 12, rotation of the drive section 5 stops rotating the drive section 5 until the second slide pin 64 moves to the closed end of the second slide slot 602, and rotation of the drive section 5 causes the third slide pin 72 to move along the fourth slide slot 103 into the third slide slot 102, such that the drive section 5 is in locking relationship with the body section 11 and can move back and forth.

Step three, performing a second insertion operation, and moving the operation driving part 5 toward the socket 2 along the axial direction of the plug 1, wherein the operation driving part is used for enabling the insertion part 4 to be inserted into the socket 2 and realizing optical fiber signal connection; since the second slide pin 64 is now located in the second slide groove 602, the drive part 5 can be moved forward relative to the plug 1. Meanwhile, inside the housing 12, on the one hand, the third sliding pin 72 has already entered the third sliding slot 102, and the fourth sliding pin 73 abutting against the fifth sliding slot 701 pushes the ring 71, so that the driving portion 5 can drive the ring 71 and the insertion portion 4 to integrally move relative to the plug 1 without being blocked; on the other hand, the plug 1 and the inside of the receptacle 2 have been communicated through the through holes 301 of the two seals 31, so that the insertion portion 4 can be inserted into the receptacle 2 through the two through holes 301 to complete the docking.

Step four, the driving part 5 is continuously rotated, the driving part 5 is rotated relative to the plug 1 and the cylinder housing 61, and the third sliding pin 72 is moved from the third sliding groove 102 into the sixth sliding groove 104 and along the sixth sliding groove 104 until the driving part 5 cannot be rotated, and the driving part 5 and the main body part 11 are locked again, so that the driving part cannot move back and forth.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
