Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of connector testing, and in particular to an underwater connector insertion and removal testing device. Background Technology
[0002] In many fields such as modern marine engineering, underwater communication, and deep-sea exploration, the performance and reliability of underwater connectors play a crucial role. However, the conventional methods currently used for testing the underwater connection performance of underwater connectors have several significant shortcomings.
[0003] Typically, the existing testing procedure involves placing the connector in a specialized water container to test its sealing performance. This process requires the use of complex sealing devices and high-precision pressure sensors to create a specific water pressure environment that simulates actual underwater pressure conditions, thereby observing whether the connector exhibits any sealing failures such as leakage under this environment.
[0004] Currently, traditional testing methods are only applicable to the performance evaluation of dry-plug watertight connectors. For wet-plug connectors, which require direct underwater insertion and removal in practical applications, existing testing methods cannot simulate this critical working scenario. This results in the inability to obtain key performance data of wet-plug connectors during actual underwater insertion and removal processes, such as dynamic changes in insertion and removal force, real-time fluctuations in contact resistance, and signal transmission stability. This creates a significant technical blind spot in the research and development and quality control of wet-plug connectors, severely restricting their promotion and application in related fields, failing to meet the growing demand for underwater equipment connections, and greatly affecting the reliability and stability of the entire underwater system.

Detailed Implementation
[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0021] The underwater connector insertion and removal testing device of this utility model embodiment will be described below with reference to the accompanying drawings.
[0022] like Figures 1-3 As shown, the underwater connector insertion and removal testing device of this utility model embodiment may include a water tank 10, a sealing end cap 20, a mounting bracket 30, a drive assembly 40, a moving clamp 50, a fixed clamp 60, and an information acquisition device 70.
[0023] The sealing end cap 20 is installed at one end of the water tank 10, which provides the water environment for testing. The sealing end cap 20 is installed at one end to ensure the water tank's airtightness during testing and prevent water leakage from affecting the test results. The sealing end cap 20 can be made of sealing materials such as rubber to enhance the sealing effect and is tightly fixed to the water tank 10 by bolts or slots.
[0024] The mounting bracket 30 may include a support frame 31, a guide rail 32, and a connecting rod 33. The support frame 31 is fixedly mounted on the bottom wall of the inner cavity of the water tank 10 away from the sealing end cap 20, providing stable support for the entire device. For example, the support frame 31 may be made of stainless steel and is firmly fixed to the bottom wall of the water tank 10 by a connecting flange to ensure that no displacement or shaking occurs during testing.
[0025] The guide rail 32 and the connecting rod 33 are arranged side by side between the support frame 31 and the sealing end cap 20, providing movement guidance and support for the movable clamp 50. The guide rail 32 can be a high-precision linear guide rail to ensure the smoothness and accuracy of the movement of the movable clamp 50, reduce frictional resistance, and extend the service life of the device.
[0026] The drive assembly 40 may include a drive mechanism 41 and a lead screw 42. The drive mechanism 41 is fixedly mounted on the connecting rod 33. In this embodiment, the drive mechanism 41 may be a bidirectional drive motor, meaning that the output end of the drive motor can switch between forward and reverse rotation. One end of the lead screw 42 is connected to the output end 41 of the drive mechanism, and the other end of the lead screw 42 is rotatably connected to the support frame 31. The rotation of the drive mechanism 41 drives the lead screw 42 to rotate, thereby realizing the linear movement of the movable clamp 50.
[0027] The movable clamp 50 is movably mounted on the guide rail 32 and is threadedly connected to the lead screw 42. The movable clamp 50 is equipped with a plug connector 80, which is connected to an external power source via a cable. The fixed clamp 60 is fixedly mounted on the guide rail 32 near the upper part of the drive mechanism 41. The fixed clamp 60 is equipped with a socket connector 90 that engages with the plug connector 80. The socket connector 90 is connected to an external power source via a cable. The information acquisition device 70 is fixedly mounted on the fixed clamp 60.
[0028] To clearly illustrate the previous embodiment, in one embodiment of this utility model, as follows: Figures 1-3 As shown, the movable clamp 50 may include a lead screw nut 51, a movable slide 52, and a first clamp 53. The lead screw nut 51 is threadedly connected to the lead screw 42, converting the rotational motion of the lead screw 42 into linear motion.
[0029] The movable slide 52 is slidably mounted on the guide rail 32, and its bottom end is fixedly connected to the lead screw nut 51, while its top end is detachably connected to the first clamp 53. This detachable connection facilitates the installation and replacement of the first clamp 53, allowing for customization based on different plug connector 80 models. For example, the movable slide 52 can be connected to the first clamp 53 via snap-fit, riveting, or threaded fasteners (screws, bolts, or bolts). The first clamp 53 is fixedly connected to the plug connector 80 via threaded fasteners.
[0030] Furthermore, in one embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the fixing fixture 60 may include a fixing platform 61 and a second fixture 62. The fixing platform 61 is fixedly mounted on the guide rail 32, and the second fixture 62 is detachably mounted on the fixing platform 61, and the second fixture 62 is fixedly connected to the socket connector 90 by threaded fasteners.
[0031] It should be noted that the first clamp 53 and the second clamp 62 described above can both be composed of arc-shaped upper and lower clamps. The two arc-shaped upper and lower clamps can be connected by threaded fasteners to fix the connector.
[0032] Furthermore, in one embodiment of this utility model, such as Figure 1As shown, the information acquisition device 70 may include a lighting lamp 71 and a camera 72. The lighting lamp 71 and camera 72 are respectively located above the socket connector 90 and are fixedly connected to the fixed platform 61 via a connecting bracket. The lighting lamp 71 and camera 72 are respectively connected to an external power source via cables. The lighting lamp 71 may be a high-brightness LED light, providing sufficient illumination in the underwater environment to facilitate clear recording of the testing process by the camera 72. The camera 72 may be a high-definition waterproof camera, capable of recording the insertion and removal process of the plug connector 80 and the socket connector 90, providing intuitive video data for subsequent analysis of test results. This helps to observe details of the connector during underwater insertion and removal, such as whether air bubbles are generated or physical changes in the connection points.
[0033] Specifically, in the actual testing process, firstly, an appropriate amount of water is injected into the water tank 10, and after reaching the predetermined water level, the sealing end cap 20 is installed. Based on the models of the plug connector 80 and socket connector 90 to be tested, appropriate first clamp 53 and second clamp 62 are selected and installed. The plug connector 80 and socket connector 90 are fixed on the movable clamp 50 and fixed clamp 60 respectively, and the corresponding cables are connected to the external power supply. Then, the drive mechanism 41 is controlled to drive the lead screw 42 to rotate. The rotating lead screw 42 drives the lead screw nut 51 to move. The moving lead screw nut 51, through the movable slide table 52, moves the plug connector 80 toward the socket connector 90 until the plug connector 80 is inserted into the socket connector 90.
[0034] When it is necessary to remove the plug connector 80 from the socket connector 90, the operator can control the drive mechanism 41 to drive the lead screw 42 to rotate in the opposite direction, thereby driving the lead screw nut 51 to move the plug connector 80 away from the socket connector 90 until the plug connector 80 is removed from the socket connector 90.
[0035] At the same time, camera 72 records the insertion and removal process of plug connector 80 and socket connector 90 in real time, providing intuitive video data for subsequent analysis and test results.
[0036] As a possible alternative, to facilitate the repeated plugging and unplugging of the plug connector 80 and the socket connector 90 within the water tank 10, a first limit switch can be installed on the support frame 31, and a second limit switch can be installed on the fixed platform 61. Both the first and second limit switches are electrically connected to the drive mechanism 41. Both the first and second limit switches can be travel switches.
[0037] Understandably, when the drive mechanism 41 drives the lead screw 42 to rotate, the rotating lead screw 42 drives the lead screw nut 51 to engage the plug connector 80 with the socket connector 90. At this time, the moving slide 52 abuts against the second limit switch. The second limit switch controls the drive mechanism 41 to drive the lead screw 42 to rotate in the opposite direction, thereby driving the lead screw nut 51 to move the plug connector 80 away from the socket connector 90. When the plug connector 80 is pulled out of the socket connector 90, the moving slide 52 abuts against the first limit switch. At this time, the first limit switch controls the drive mechanism 41 to rotate in the forward direction. The lead screw 42 drives the lead screw nut 51 to move the plug connector 80 towards the socket connector 90, thus realizing the repeated automatic plugging and unplugging action of the connector. The camera 72 records the plugging and unplugging process of the plug connector 80 and the socket connector 90 in real time, thereby accurately simulating the actual working conditions when plugging and unplugging underwater, effectively improving the comprehensiveness and accuracy of underwater connector testing.
[0038] In another embodiment of this utility model, such as Figure 4 As shown, the aforementioned underwater connector insertion and removal testing device may further include a separation mechanism 100. The separation mechanism 100 may include an extension arm 110, a handle bolt 120, and a pressure rod 130. One end of the extension arm 110 is detachably connected to the movable slide 52, facilitating disassembly when separation testing is not required, without affecting normal insertion and removal testing. The other end of the extension arm 110 is threadedly connected to the handle bolt 120.
[0039] The pressure rod 130 is inclinedly mounted on the handle bolt 120, and the angle between the pressure rod 130 and the extension arm 110 is 45°. During the 45° separation test, the pressure rod 130 can be operated by manipulating the handle bolt 120 to apply a separation force to the plug connector 80, simulating special separation situations that may occur in actual use, and testing the performance of the connector under this condition.
[0040] Understandably, the operator can remove the movable clamp 50, manually insert the connector, and then apply a 45° separation force to the plug connector 80 via the top pressure rod 130, recording the separation process data to test the plug's tilt separation performance. This enables the device to support automatic / manual operation, multi-parameter feedback, and 45° separation testing.
[0041] In summary, the underwater connector insertion and removal testing device of this utility model can accurately simulate the actual working conditions when it is inserted and removed underwater, effectively improving the comprehensiveness and accuracy of underwater connector testing.
