The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art. The following describes an embodiment of the present invention according to its overall structure.

Referring to fig. 1-3, a military threaded waterproof connector includes a connector housing 1, a docking seat 2, an elastic ring 3, an adjustable rod 4, an adjustable plate 5, a patch cord 6, a primary sealing ring 7, a pressure plate 8, a water absorbing ring 9, a secondary sealing ring 10, a first thread groove 11, a second thread groove 12 and a third thread groove 13, the docking seat 2 is installed at both ends of the connector housing 1, the patch cord 6 is installed at one side of the docking seat 2, the first thread groove 11, the second thread groove 12 and the third thread groove 13 are respectively installed at one side of the interior of the docking seat 2, the primary sealing ring 7, the water absorbing ring 9 and the secondary sealing ring 10 are respectively installed at one side of the first thread groove 11, the second thread groove 12 and the third thread groove 13, a plurality of adjustable rods 4 are respectively penetrated through the top and the bottom of the connector housing 1, the adjustable plate 5 is fixed at the top ends of the plurality of adjustable rods 4, the pressure plate 8 is fixed at the bottom ends of the plurality of adjustable rods 4, elastic rings 3 are sleeved on two sides of the outer surface of the connector shell 1.

Please refer to fig. 1-2, the adjustable rods 4 are slidably engaged with the connector housing 1, the outer surfaces of the adjustable rods 4 are covered with rubber pads, so that external air and water can not enter the connector through the connection between the adjustable rods 4 and the connector housing 1, the pressing plate 8 is slidably engaged with the inner wall of the connector housing 1, and the outer surface of the pressing plate 8 is smooth, so that the pressing plate 8 can slide to compress the inner space of the connector housing 1 and increase the internal pressure.

Please refer to fig. 1-3, the area of the water absorption ring 9 is larger than the area of the secondary sealing ring 10, the area of the primary sealing ring 7 is larger than the area of the water absorption ring 9, so that the primary sealing ring 7, the water absorption ring 9 and the secondary sealing ring 10 cooperate with each other to play a waterproof role, and the two elastic rings 3 are respectively located at two sides of the two adjustable plates 5, so that the elastic rings 3 can be sleeved on the adjustable plates 5 to be fixed after being pulled and moved.

The working principle is as follows: firstly, when the plug wire 6 is connected with the connector through the butt joint seat 2, a user can screw the main sealing ring 7, the water absorbing ring 9 and the secondary sealing ring 10 into the first thread groove 11, the second thread groove 12 and the third thread groove 13 respectively through threads in sequence, the connection part of the plug wire 6 and the butt joint seat 2 is sealed and waterproof preferentially by the main sealing ring 7 which is positioned at the outermost periphery, then even if water passes through the main sealing ring 7, the water can be absorbed and blocked by the water absorbing ring 9, then the connection part of the plug wire 6 and the butt joint seat 2 can be sealed again through the secondary sealing ring 10, so that the waterproof performance of the connector is ensured, meanwhile, after the connector is installed, the user can press the adjustable plate 5 to enable the adjustable rod 4 to press the pressure plate 8 towards the inside of the connector shell 1 and fix the adjustable plate 5 through the elastic ring 3, and the operation can increase the internal pressure of the connector, therefore, when water can sequentially pass through the main sealing ring 7, the water absorption ring 9 and the secondary sealing ring 10, the water can be extruded by the force larger than the external air pressure inside the connector, and the waterproof effect of the connector can be improved again.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
