[0023] The following will describe in detail various aspects of the embodiments of the present application in conjunction with the accompanying drawings:

[0024] like Figure 1The wet electrical connector immersion test device shown includes an electric hydraulic pump 1, an oil-water pressure converter 3, a pressure chamber 2, and a high-pressure oil pipe 4 connecting the electric hydraulic pump 1, the oil-water pressure converter 3 and the pressure chamber 2. The pressure chamber 2 is a cylinder, including a top cover 9, a bottom cover 11 and a side wall 10, and is filled with insulating oil; a four-way joint 8 is provided on the top cover 9, and the other three joints of the four-way joint 8 are respectively connected to a one-way valve 5, a pressure sensor 7 and a pressure gauge 6, and the other end of the one-way valve 5 is connected to the high-pressure oil pipe 4, so the four-way joint 8 connects the electric pressure pump 1 with the pressure chamber 2, so that the electric pressure pump 1 can apply pressure to the pressure chamber 2, and the pressure sensor 7 and the pressure gauge 6 detect and display the real-time pressure in the pressure chamber. The pressure chamber 2 is vertically set up by a pressure chamber support frame 19; the cylinder 18 is arranged outside the pressure chamber 2, and is fixedly connected to the outer wall of the bottom cover 11 of the pressure chamber through a cylinder bracket 17.

[0025] Look again Figure 2 , Figure 3 and Figure 4 , Figure 2 for Figure 1 A front view of the embodiment shown, Figure 3 yes Figure 2 A cross-sectional view of the BB, Figure 4 yes Figure 2 A cross-section in another direction; Figure 3 It can be seen that an electric connector support guide frame 14 is provided in the pressure chamber 2 and is fixed to the inner wall of the bottom cover. The electric connector support guide frame 14 is fixedly connected to the electric connector female connector fixing plate 12 and is slidably connected to the electric connector male connector fixing frame 13, so that the electric connector male connector fixing frame 13 can move linearly close to or away from the electric connector female connector fixing plate 12 along the electric connector support guide frame 14 when subjected to force. Specifically, a hole is provided on the bottom cover 11 for the transmission rod 15 to pass through. The cylinder 18 is fixedly connected to the electric connector male connector fixing frame 13 through the transmission rod 15. The transmission rod 15 is sealedly connected to the bottom cover 11 through the transmission rod sealing assembly 16, so that the cylinder 18 and the electric connector male connector fixing frame 13 are sealed and indirectly connected.

When the cylinder 18 is working, it outputs power to the transmission rod 15, and the transmission rod 15 pushes the male connector fixing frame 13 of the electrical connector to move vertically upward along the electrical connector support guide frame 14, that is, drives the male connector 30 of the electrical connector to approach the female connector 20 of the electrical connector and finally combines the two, and then simulates the situation of seawater at different depths, that is, the electric hydraulic pump is used to provide power to achieve pressurization of the seawater. The working mode is: the electric hydraulic pump boosts the pressure, and the oil pressure is converted into seawater pressure through the oil-water pressure converter. The pressure in the pressure chamber is displayed by the pressure gauge and can also be displayed in real time through the pressure sensor. For example: when the pressure reaches 10MPa (1MPa seawater pressure is approximately equal to the depth of 100m seawater), it can simulate the state of the electrical connector at a depth of 1000m seawater. At this time, the insulation test, voltage resistance test and other related electrical parameter tests of the electrical connector can be carried out through the through-chamber cable connected to the end of the electrical connector.
