It should be noted that, the sliding member 132 is provided with a second channel 135, and the column 133 is disposed through the second channel 135, that is, the sliding member 132 is sleeved on the column 133.
Specifically, during plugging engagement, the body 111 abuts against the inner wall of the housing 131, then approaches the slider 132, abuts against the slider 132, and abuts against the plunger 112 and the post 133, and under the action of external force, the slider 132 moves in a direction away from the body 111, so that the post 133 protrudes relative to the slider 132, and under the action of the post 133, the plunger 112 moves in a direction away from the post 133, so as to communicate with the first accommodating groove 115 and the second accommodating groove 136, and further, the first optical fiber stub 113 and the second optical fiber stub 134 are abutted. It should be noted that, the axis of the first accommodating groove 115 is perpendicular to the axis of the first channel 114, the axis of the second accommodating groove 136 is perpendicular to the axis of the second channel 135, and since the axis of the first channel 114 and the axis of the second channel 135 are coincident, it is understood that the axis of the first accommodating groove 115 and the axis of the second accommodating groove 136 are parallel, so when the axis of the first accommodating groove 115 and the axis of the second accommodating groove 136 are coincident, the first accommodating groove 115 is aligned with the second accommodating groove 136, and the first optical fiber butt joint 113 is moved from the first accommodating groove 115 to the second accommodating groove 136 and is butt jointed with the second optical fiber butt joint 134.

The working principle of the underwater wet plug connection device 100 is as follows:
Before docking, the plunger 112 seals the first accommodating groove 115, and the sliding member 132 seals the second accommodating groove 136, so that a closed space is formed, so that the first optical fiber butt joint 113 and the second optical fiber butt joint 134 are in a sealed environment before docking, and the influence of marine organisms on the transmission effect and the service life of the optical fiber butt joint before docking is avoided.
During the mating process, one end of the body 111 of the male plug 110 extends into the housing 131 and moves in the direction of the slider 132 to abut against the slider 132, and at this time, the plunger 112 abuts against the cylinder 133. Under the action of external force, the sliding member 132 moves in a direction away from the body 111, that is, the sliding member 132 moves in the axial direction thereof toward the inside of the female plug 130, the plunger 112 moves in a direction away from the cylinder 133, that is, the plunger 112 moves in the axial direction thereof toward the inside of the male plug 110, so that the plunger 112 opens the first accommodating groove 115, the cylinder 133 extends into the first channel 114, so that the second accommodating groove 136 moves from the second channel 135 to the first channel 114, thereby communicating with the first accommodating groove 115, and the first optical fiber butt joint 113 and the second optical fiber butt joint 134 are connected.
After the first optical fiber splice 113 and the second optical fiber splice 134 are mated, i.e., after the male plug 110 and the female plug 130 are mated, the male plug 110 and the female plug 130 are locked. At this time, the first optical fiber butt joint 113 and the second optical fiber butt joint 134 are still in a blocking state with the outside, so that the first optical fiber butt joint 113 and the second optical fiber butt joint 134 are still in an environment of sealing after the male plug 110 and the female plug 130 are in butt joint, so as to avoid the influence of seawater and marine organisms on the transmission effect and service life of the optical fiber butt joint after butt joint.
The first optical fiber butt-joint 113 and the second optical fiber butt-joint 134 are both connected by optical fibers, so that information transmission is realized when the optical fibers are in butt joint.
Further, in the embodiment of the present invention, there are various configurations for the first optical fiber butt-joint 113 and the second optical fiber butt-joint 134 to be abutted, for example, the first optical fiber butt-joint 113 is movably disposed in the first accommodating groove 115 and has a tendency to move toward the first channel 114, or the second optical fiber butt-joint 134 is movably disposed in the first accommodating groove 115 and has a tendency to move toward the sliding member 132. In practice, one or both configurations may be selected to interface the first fiber optic splice 113 and the second fiber optic splice 134.
In the present embodiment, the first optical fiber butt joint 113 is movably disposed in the first accommodating groove 115 and has a tendency to move toward the first channel 114, the plunger 112 includes a blocking portion 116 and a supporting portion 117, the blocking portion 116 is connected with the supporting portion 117, the diameter of the supporting portion 117 is smaller than that of the blocking portion 116, and the blocking portion 116 is slidably matched with the first channel 114, wherein the blocking portion 116 blocks the first accommodating groove 115 when the male plug 110 and the female plug 130 are disengaged, and the blocking portion 116 opens the first accommodating groove 115 when the male plug 110 and the female plug 130 are in plug-in matching.
Specifically, before docking, the end face of the abutting portion and the end face of the body 111 are located on the same plane, and the blocking portion 116 blocks the first accommodating groove 115, so that the first optical fiber butt joint 113 is located in the sealed environment. In the abutting process, the abutting portion abuts against the sliding member 132, and under the action of external force, the plunger 112 moves towards the inside of the male plug 110 in the axial direction of the plunger, so that the blocking portion 116 opens the first accommodating groove 115, the abutting portion 117 approaches the first accommodating groove 115, and the diameter of the cross section of the abutting portion 117 in the direction perpendicular to the extending direction of the abutting portion is smaller than that of the cross section of the blocking portion 116 in the direction perpendicular to the extending direction of the abutting portion, so that a certain movable space is provided for the first optical fiber butt joint 113, and the first optical fiber butt joint can move from the first accommodating groove 115 to the first channel 114, so that the first accommodating groove 115 and the second accommodating groove 136 can move into the second accommodating groove 136 continuously when being communicated. When the blocking portion 116 opens the first accommodating groove 115, a portion of the first optical fiber butt joint 113 extends into the first channel 114, and a diameter of a cross section of the pillar 133 perpendicular to the extending direction thereof is equal to a diameter of a cross section of the abutting portion 117 perpendicular to the extending direction thereof, so that the first optical fiber butt joint 113 and the second optical fiber butt joint 134 can be smoothly abutted when the second accommodating groove 136 is opposite to the first accommodating groove 115.
Further, the male plug 110 further includes a first elastic member 121, two ends of the first elastic member 121 are respectively connected to the body 111 and the first optical fiber butt joint 113, and the first elastic member 121 is configured to enable the first optical fiber butt joint 113 to have a tendency to move from the first accommodating groove 115 to the first channel 114. Before docking, the blocking portion 116 blocks the first receiving groove 115, thereby compressing the first elastic member 121, and when the blocking portion 116 opens the first receiving groove 115, the first elastic member 121 is restored to return to the original state, so that the first optical fiber docking head 113 is moved toward the first channel 114 by the first receiving groove 115 under the elastic force of the first elastic member 121.
In combination with the above, a first guiding inclined surface 118 is provided at the connection portion of the blocking portion 116 and the abutting portion 117, wherein the first guiding inclined surface 118 is used for connecting with the first optical fiber butt joint 113 when the plunger 112 moves toward the column 133, and guiding the first optical fiber butt joint 113 to move from the first channel 114 to the first accommodating groove 115. The first optical fiber abutment 113 is provided with a second guiding ramp 119, the second guiding ramp 119 being adapted to contact the first guiding ramp 118. When the first accommodating groove 115 is to be plugged again for the plugging portion 116, the first optical fiber butt joint 113 is moved upward by the first guide inclined surface 118 and the second guide inclined surface 119, so that all the optical fibers return to the first accommodating groove 115, and the phenomenon that the plugging portion 116 abuts against the first optical fiber butt joint 113 in the moving process is avoided.
The male plug 110 further includes a second elastic member 122 disposed in the first channel 114, where the second elastic member 122 is configured to enable the plunger 112 to have a tendency to move toward the body 111 for abutting against the sliding member 132 to block the first accommodating groove 115. The female plug 130 further includes a third elastic member 137 disposed in the housing 131, and the third elastic member 137 is configured to enable the sliding member 132 to have a tendency to move toward the end of the post 133 for abutting against the plunger 112, so as to block the second accommodating groove 136.
Specifically, in the present embodiment, when the male plug 110 and the female plug 130 are mated, the plunger 112 and the cylinder 133 abut against each other, the plunger 112 moves in the direction of the second elastic member 122 under the action of external force, thereby compressing the second elastic member 122, the body 111 and the slider 132 abut against each other, and the slider 132 moves in the direction of the third elastic member 137 under the action of external force, thereby compressing the third elastic member 137 until the first optical fiber butt joint 113 and the second optical fiber butt joint 134 are mated. Thereby, when the male plug 110 and the female plug 130 are disassembled, the second elastic member 122 and the third elastic member 137 are released to be restored to the original state, thereby causing the plunger 112 to move toward the end for abutting against the slider 132 under the action of elastic force to block the first receiving groove 115, i.e., to move toward the outside of the male plug 110 in the axial direction, and the slider 132 to move toward the end abutting against the plunger 112 under the action of elastic force to block the second receiving groove 136, i.e., to move toward the outside of the female plug 130 in the axial direction.
Further, the first channel 114 includes a first segment and a second segment, the first segment is communicated with the second segment, the inner diameter of the first segment is smaller than that of the second segment, and the first accommodating groove 115 is communicated with the second segment, wherein the first segment is used for being matched with the abutting portion 117, and the second segment is used for being matched with the blocking portion 116.

In order to prevent the blocking portion 116 from entering the first section from the second section during the assembly and disassembly, the inner diameter of the first section is smaller than the diameter of the blocking portion 116. And, a third guiding inclined surface 126 is provided at the junction of the first and second segments for cooperating with the first guiding inclined surface 118 to improve the sealing property of the first receiving groove 115.
