Technical Field
[0001] The present invention relates to the technical field of electrical connector testing, and specifically to a device and method for testing the water pressure resistance of a watertight component. Background Technique
[0002] Watertight cable assemblies are widely used in fields such as ocean engineering, underwater equipment, and ships. One of their core performances is the ability to maintain good sealing and electrical performance in a high-pressure liquid environment. To ensure the reliability of watertight cable assemblies, it is necessary to strictly test their water pressure resistance.
[0003] Traditional testing methods usually pre-sleeve a complete rubber plug on the watertight cable before assembling the watertight component to achieve the seal between the watertight cable and the water pressure resistance testing tooling. After the test is completed, the rubber plug is removed from the watertight cable by damaging the rubber plug. When the rubber plug is removed, it is no longer possible to test the water pressure resistance of the watertight component, which is not conducive to subsequent quality re-inspection and detection. Summary of the Invention

Among them, the pressure tank 1 includes a tank body 101, a first cover plate 102, and a second cover plate 103. The first cover plate 102 and the second cover plate 103 are respectively fixedly installed at both ends of the tank body 101 through long bolts 105. To ensure the sealing effect, a first sealing ring 104 is embedded on the side of the first cover plate 102 and the second cover plate 103 close to the tank body 101.
[0017] As a preferred solution, the pressurizing assembly 8 is arranged on one side of the pressure tank 1 and is communicated with the pressure tank 1. Specifically, a first through hole 106 that cooperates with the pressurizing assembly 8 is opened on the surface of the second cover plate 103.
[0018] As a preferred solution, the watertight cable assembly 2 penetrates through the other side of the pressure tank 1 and extends into the interior of the pressure tank 1. Specifically, a second through hole 107 for cooperating with the watertight cable assembly 2 is formed on the surface of the first cover plate 102. The watertight cable assembly 2 is a watertight cable already equipped with a watertight connector, and the watertight connector is placed inside the pressure tank 1 for watertight testing.
[0019] As a preferred solution, in order to ensure the sealing effect of the watertight test, a sealing assembly 10 for cooperating with the watertight cable assembly 2 is further provided inside the pressure tank 1. The sealing assembly 10 includes a fixed cylinder 7. The fixed cylinder 7 is fixedly installed on one side of the second cover plate 103, and the fixed cylinder 7 is communicated with the second through hole 107. In order to ensure the connection tightness, a second sealing ring 9 is embedded at one end of the fixed cylinder 7 close to the second cover plate 103. Two first semi-circular hole gaskets 3, two rubber plugs 4 and two second semi-circular hole gaskets 5 are sequentially arranged inside the fixed cylinder 7 from right to left. A first flange 703 is fixedly installed on the left side of the fixed cylinder 7. A pressing member 6 is fixedly installed on one side of the first flange 703 through screws. The pressing member 6 includes a second flange 601. A circular pressing plate 603 is fixedly installed on one side of the second flange 601, and the circular pressing plate 603 cooperates with the two second semi-circular hole gaskets 5. A plurality of circular holes 602 and threaded holes 705 for cooperating with each other are respectively formed on the surfaces of the second flange 601 and the first flange 703.
[0020] Further explanation, the two first semi-circular hole gaskets 3, the two rubber plugs 4 and the two second semi-circular hole gaskets 5 are all sleeved on the outer periphery of the watertight cable assembly 2, and the outer arc surfaces of the two first semi-circular hole gaskets 3, the two rubber plugs 4 and the two second semi-circular hole gaskets 5 are all in sliding contact with the inner surface of the fixed cylinder 7. Among them, one side of the inside of the fixed cylinder 7 close to the second cover plate 103 is a cylindrical surface one 704, and the other side of the inside of the fixed cylinder 7 far from the second cover plate 103 is a cylindrical surface two 702. The outer periphery of the circular pressing plate 603 cooperates with the cylindrical surface two 702. The inside of the fixed cylinder 7 is communicated with the cylindrical surface one 704 and the cylindrical surface two 702 through a conical surface 701. A semi-circular hole 402 for cooperating with the watertight cable assembly 2 is formed on the opposite side of the two rubber plugs 4. One end of the rubber plug 4 is a semi-conical structure 401, and the semi-conical structure 401 cooperates with the conical surface 701. The other end of the rubber plug 4 is a semi-cylindrical structure 403, and the semi-cylindrical structure 403 cooperates with the cylindrical surface two 702.
[0021] It should be noted that the inner holes of the first semi-circular hole gasket 3 and the second semi-circular hole gasket 5, as well as the semi-circular hole 402, are all matched with the outer diameter of the watertight cable in the watertight cable assembly 2.
[0022] The usage method of the device for testing the water pressure resistance of the above-mentioned watertight component specifically includes the following steps: Step 1: One end of the watertight cable assembly 2 sequentially passes through the second through hole 107 and the fixing cylinder 7. Then, two first semi-circular hole gaskets 3 are placed in the right cavity of the fixing cylinder 7 and sleeved on the outer periphery of the watertight cable assembly 2. Then, the operation is repeated, and two rubber plugs 4 and two second semi-circular hole gaskets 5 are sequentially placed. The circular ring pressing plate 603 is sleeved on one end of the watertight cable assembly 2. After aligning the circular hole 602 and the threaded hole 705, use a screw to pass through the circular hole 602 and threadedly cooperate with the threaded hole 705. Tighten the screw to squeeze the circular ring pressing plate 603 to squeeze the two second semi-circular hole gaskets 5. The two second semi-circular hole gaskets 5 squeeze the two rubber plugs 4, and the two rubber plugs 4 squeeze the two first semi-circular hole gaskets 3. During the process, the two rubber plugs 4 are deformed to achieve the sealed coating of the watertight cable assembly 2; Step 2: After using the long bolt 105 to fix the second cover plate 103 at one end of the tank body 101, inject a set amount of liquid into the tank body 101, and then use the long bolt 105 to fix the first cover plate 102 at the other end of the tank body 101; Step 3: The pressurizing component 8 applies the required pressure to the liquid in the tank body 101 to start the water pressure resistance test of the watertight cable assembly 2. After the test is completed, sequentially remove the second cover plate 103, the circular ring pressing plate 603, the two second semi-circular hole gaskets 5, the two rubber plugs 4, and the two first semi-circular hole gaskets 3, and then pull out the watertight cable assembly 2 from the second through hole 107 to complete the water pressure resistance test of the watertight cable assembly 2.
