[0002] Among various marine technologies, submarine communications are the basic condition for the realization of other technologies. Therefore, marine optical cables and deep-sea watertight connectors play a key role in signal transmission and connection. Deep-sea watertight connectors are divided into dry plug connectors and wet plug connectors according to the plug-in type. The former plugs and sockets are directly put into the water for use after docking on land, while the latter plugs and sockets need to be docked in water before use. In order to verify the long-term reliability of the product, watertight connectors undergo relevant underwater tests according to the standards. Dry plug connector plugs and sockets are tested as a whole. The difference between wet plug and pull is that it needs to verify the performance changes when plugging and unplugging underwater.

It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0025] like Figure 1 As shown, in this embodiment, the underwater plug-in test device includes: a first bracket 10, a second bracket 20, a driving structure 30 and a shooting structure. The second bracket 20 is arranged on the first bracket 10, and the second bracket 20 is used to fix the first connector. The driving structure 30 includes a power source 31 and a driving member 32, and the power source 31 and the driving member 32 are both arranged on the first bracket 10. The driving member 32 is movably arranged and can drive the second connector to move, and the second connector is plugged in or disconnected with the first connector. The shooting structure is arranged on the first bracket 10 and faces the first connector and the second connector. The angle of the shooting structure is adjustable.

[0026] According to the technical solution of this embodiment, the second bracket 20 is arranged on the first bracket 10, and the second bracket 20 can fix the first connector. The driving structure 30 includes a power source 31 and a driving member 32. The power source 31 and the driving member 32 are both arranged on the first bracket 10. The driving member 32 is movably arranged and can drive the second connector to move, thereby driving the second connector to plug and match with the first connector or disconnecting the second connector from the first connector. The shooting structure is arranged on the first bracket 10 and faces the first connector and the second connector. At the same time, the angle of the shooting structure is adjustable. Through the above arrangement, the first bracket 10 can effectively fix the driving structure 30, the shooting structure and the second bracket 20, and the second bracket 20 can fix the first connector, so that the positions of the driving structure 30, the shooting structure and the first connector are more stable. At the same time, under the action of the driving member 32, the first connector and the second connector can be driven to plug and match. The shooting structure can shoot the plugging process of the first connector and the second connector, thereby realizing the observation of the plugging and unplugging process of the first connector and the second connector, thereby obtaining real-time data. And because the angle of the shooting structure is adjustable, the shooting can be made clearer and more accurate by adjusting the angle. Specifically, when testing, the underwater plug-in test device is placed underwater, and the second connector is driven to move by the driving structure 30, thereby realizing the plug-in test underwater. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that it is difficult to realize the plug-in test of the connector underwater, thereby affecting the test effect.

[0027] A single hydrostatic pressure test cannot truly reflect the performance changes of wet-plug connectors in complex environments. This is also a drawback of current wet-plug connector testing. In order to truly simulate the performance of wet-plug connectors, it is necessary to form online performance detection of plugging and unplugging in a water pressure environment and plugging and unplugging capabilities under turbid water pressure. The technical solution of this embodiment can realize underwater plug-in testing and thus improve the test effect.

[0028] Specifically, in this embodiment, the underwater plug-in test device further includes an underwater light, which is directed toward the first connector and the second connector, thereby making the shooting structure clearer. The shooting device connects the entire loop to the outside of the underwater plug-in test device and the lead wire through a branch flying line, and the connection of an external device can monitor the plug-in status of the first connector and the second connector in real time.

[0029] like Figures 1 to 3As shown, in this embodiment, the driving member 32 includes a driving cylinder 321 and a guide rod 322. The guide rod 322 is connected to the driving end of the driving cylinder 321. The guide rod 322 extends into the second bracket 20 and is connected to the second connector. The guide rod 322 can extend the length of the driving cylinder 321 and make it better connected to the second connector. In addition, the guide rod 322 can be guided and matched with the second bracket 20, so that the moving direction of the guide rod 322 is more stable and not prone to deflection, thereby ensuring that the first connector and the second connector will not be misaligned when plugged in.

[0030] In this embodiment, the power source is a cylinder, and the maximum plugging and unplugging force is designed according to the inner diameter of the cylinder barrel and the pressure at the cylinder input end. Conversely, the inner diameter of the cylinder barrel and the pressure at the cylinder input end can also be reversely designed according to the maximum plugging and unplugging force requirements of the product. When plugging and unplugging, the plugging and unplugging force is set to avoid excessive plugging and unplugging force from damaging the first connector and the second connector.

[0031] like Figures 1 to 3 As shown, in this embodiment, a connecting hole 3221 is provided at the end of the guide rod 322 facing the drive cylinder 321, and the driving end of the drive cylinder 321 is adjustably inserted into the connecting hole 3221. The above arrangement enables the distance between the guide rod 322 and the drive cylinder 321 to be adjustable, thereby enabling the first connector and the second connector of different sizes to be matched.

[0032] like Figures 1 to 3 As shown, in this embodiment, the driving member 32 further includes an adjusting member 323, which is disposed on the guide rod 322 and cooperates with the driving end of the driving cylinder 321. The arrangement of the adjusting member 323 can effectively achieve adjustment, thereby adjusting the position of the guide rod 322.

[0033] like Figures 1 to 3 As shown, in this embodiment, the adjusting member 323 includes an adjusting nut 3231, which is arranged at the end of the guide rod 322, the axis of the adjusting nut 3231 coincides with the center line of the connecting hole 3221, and a threaded structure matching the adjusting nut 3231 is arranged on the driving end of the driving cylinder 321. The adjusting nut 3231 has a simple structure and is easy to set.

[0034] like Figure 1 As shown, in this embodiment, the first bracket 10 includes a first mounting plate 11, a second mounting plate 12, and a connecting frame 13 connected between the first mounting plate 11 and the second mounting plate 12, and the second bracket 20, the driving structure 30 and the power source 31 are all arranged on the connecting frame 13. The first bracket 10 has a simple structure, is easy to set up, and has a good overall structural strength, which can effectively protect the structure inside it.

[0035] like Figure 1 As shown, in this embodiment, the first mounting plate 11 is provided with an avoidance hole 111, and the avoidance hole 111 is provided corresponding to the power source 31. The avoidance hole 111 can pass through the watertight cable, thereby realizing online performance testing of the first connector and the second connector. For example, online testing of insulation resistance, withstand voltage, and electrical continuity. These items can also reflect whether the sealing performance of the connector is reliable. If the sealing performance fails, its electrical performance will not meet the requirements.

[0036] like Figure 1 As shown, in this embodiment, the connecting frame 13 includes a plurality of connecting rods 131 arranged at intervals and a plurality of connecting rings 132 connected to the outer peripheries of the plurality of connecting rods 131. There is a hollow area between the plurality of connecting rods 131 and the plurality of connecting rings 132, so that water can directly contact the first connector and the second connector, and at the same time, the first connector and the second connector can be protected from being hit.

[0037] like Figure 1 As shown, in this embodiment, the underwater plug-in test device further includes a support structure 40, which is disposed between the second mounting plate 12 and the second bracket 20. The arrangement of the support structure 40 can support the second bracket 20, thereby making the position of the second bracket 20 more stable. Specifically, in this embodiment, the support structure 40 supports the second bracket 20, thereby avoiding the controller 50.

[0038] Of course, in an embodiment not shown in the drawings, the support structure can be arranged to be raised and lowered.

[0039] like Figure 1 As shown, in this embodiment, the underwater plug-in test device further includes a controller 50, which is controllably connected to the power source 31. The controller 50 can control the start and stop of the drive structure, and specifically, the controller 50 can control the start, stop and moving speed of the drive structure 30 according to the real-time test results.

[0040] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0041] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0042] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0043] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
