In the process of separation, the socket body 21 and the ferrule 11 are separated, and in the process of separation.

In the present utility model, the outer casing 22 is fixedly connected to the socket member 20 and integrally formed, the threaded sleeve 12 is movably sleeved on the plug member 10, and the threaded sleeve 12 can be axially displaced along the plug member 10.

When the plugging action is performed, the ferrule 11 and the socket body 21 are combined, that is, the pins are inserted into the jacks to realize the electric connection of the connector.

Before the plugging action, the sleeve member 30 is sleeved on the ferrule 11 or the socket body 21, so that the sleeve body 32 of the sleeve member 30 is inserted into the buffer cavity 23, and since the sleeve body 32 is of the same diameter as the ferrule 12 and the socket body 21, the inner walls of the sleeve body 32 and the socket body 21 are closely attached to the inner walls of the sleeve body 32 (a cavity for accommodating the sleeve body 32 is also arranged between the ferrule 11 and the sealing ring 13).

The sleeve body 32 of the present utility model is made of rubber or plastic material having elastic deformation. The sleeve body 32 is bent in the buffer chamber 23, or the end of the sleeve body 32, which is positioned in the buffer chamber 23, is provided with a sphere having the same diameter as the buffer chamber 23, so that the buffer chamber 23 is sealed.

Even if the plugging action is performed at the water bottom, the sleeve body 32 which can be deformed can isolate water in the buffer cavity 23 between the outer wall of the sleeve body 32 and the inner wall of the outer sleeve shell 22, thereby realizing the sealing action.

The end of the outer casing 22 facing the ferrule 11 is provided with a locking ring 25, the locking ring 25 is in threaded connection with the end of the outer casing 22, and the purpose of the locking ring 25 is to screw in along the axial thread of the outer casing 22 and apply a force to the sleeve body 32 along the radial direction of the socket body 21, so that the interior of the sleeve body 32 is sealed with the ferrule 11 and the socket body 21 after being inserted and isolated from the buffer cavity 23.

The circumferential surface of the locking ring 25 is provided with a second thread ring 27 cooperating with the thread bushing 12, the purpose of which is to further effect the connection of the locking ring 25 and the thread bushing 12, thereby further sealing the connected portion of the socket body 21 and the ferrule 11.

The socket body 21 is provided with an end seal 26, and the end seal 26 is located at a side of the second thread ring 27 away from the plugging end.

The inner wall of the end part of the threaded sleeve 12 facing the plugging end is provided with the inner concave ring 14 matched with the end sealing ring 26, the purpose of the threaded sleeve is to realize the sealing of the end part of the threaded sleeve 12, and even if the outer diameter of the end sealing ring 26 is larger than the outer diameter of the inner concave ring 14 (i.e. interference fit) by rotating the threaded sleeve 12, the end sealing ring 26 and the inner concave ring 14 can be matched through the deformation of the end sealing ring 26, and the position of the end sealing ring 26 can be prevented from being changed in the process of the matching of the end sealing ring 26 and the inner concave ring.

The end seal 26 is located at the front end of the internal thread of the thread bush 12 (as viewed from the end of the thread bush 12 being able to enter the interior of the thread bush 12), so that the threaded portion of the thread bush 12 can be prevented from being in direct contact with the water body, and further the possibility of rust on the threaded connection portion within the thread bush 12 can be reduced.

The locking ring 25 comprises an equal-diameter ring body 251, one side of the equal-diameter ring body 251 is connected with a threaded pipe fitting 252, the outer wall of the threaded pipe fitting 252 is in threaded connection with the inner wall of the end part of the outer casing 22, the side edge, far away from the equal-diameter ring body 251, of the threaded pipe fitting 252 is connected with a plurality of flap edges 253, and the flap edges 253 are arranged on the side edge of the equal-diameter ring body 251 in an equidistant annular array.

Although in the above-described solution, the sleeve body 32 is made of a deformable flexible material, such as silica gel or rubber, and the sleeve body 32 needs to have deformability and also needs to have a certain hardness and toughness, so as to resist deformation caused by the force applied during the plugging action of the ferrule 11 and the socket body 21, and the purpose is to seal the buffer chamber 23 by deformation of the sleeve body 32 in the buffer chamber 23, and obviously, such deformation is not regular or has ideal sealing property for the buffer chamber 23.

Therefore, the guide rib 254 is provided inside the present utility model, and the guide rib 254 is used to achieve the convergence of the plurality of flaps 253 toward the axis of the ferrule 11, so that the plurality of flaps 253 of the locking ring 25 are restrained by the guide rib 254 while moving in the axial direction of the buffer chamber 23 during the plugging operation of the ferrule 11 and the socket body 21, and thus the flaps 253 are overlapped to move in the radial direction of the socket body 21, and the sleeve body 32 is pressed toward the socket body 21.

Of course, the flap 253 presses the sleeve body 32 to contact the outer circumferential surface of the socket body 21, and simultaneously divides the sleeve body 32 into an inner cavity and an outer cavity, the cavity where the connection part of the ferrule 11 and the socket body 21 is located is isolated from the cavity of the buffer cavity 23, and the sleeve body 32 positioned in the buffer cavity 23 deforms under the extrusion action to seal the sleeve body.

The buffer chamber 23 can also be designed between the sealing ring 13 and the insert 11 in the present utility model.

The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application, the scope of which is defined by the claims. Various modifications and equivalent arrangements may be made to the present application by those skilled in the art, which modifications and equivalents are also considered to be within the scope of the present application.
