[0002] Subsea communications are essential for marine resource development, ocean exploration, underwater weapon systems, and other fields. Board-to-board deep-sea connectors have become a crucial bridge between devices on the seabed. Due to the unique nature of deep-sea working environments, board-to-board underwater electrical connectors must possess stable and reliable electrical performance. Furthermore, given the harshness of the deep-sea environment, underwater damage is difficult to repair, resulting in long repair cycles and significant losses. Therefore, pre-installation testing with test sockets is essential to ensure performance meets requirements during full operation.

[0003] When the existing underwater connector test socket is docked with the plug under test, there is a problem that the position between the test socket and the plug under test is not unique. However, for most products, such as seven-core products, it is necessary to distinguish the main key position during testing, so it is necessary to ensure that the position between the test socket and the plug under test is unique. The existing underwater connector test socket cannot meet the above requirements. Utility Model Content

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] Example 1

[0030] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 As shown, an underwater connector test socket with an anti-fool mechanism is used in conjunction with a plug to be tested. The plug to be tested includes a plug housing 10, and a convex key 12 is provided on the outer wall of the plug housing 10. The socket includes,

[0031] The housing 20, the plug end of the housing 20 extends axially to form a plate 23;

[0032] A locking sleeve 30 is sleeved on the outside of the housing 20 and rotatably engaged with the outer wall of the housing 20;

[0033] A snap ring 40 is located within the locking sleeve 30 and is threadedly engaged with the locking sleeve 30. A guide through-hole 42 is formed axially therethrough in the snap ring 40. A plurality of elastic claws 43 are axially extended from the end of the snap ring 40. The area enclosed by the plurality of elastic claws 43 forms a cavity 45. Guide grooves 41 of varying sizes are formed between adjacent two elastic claws 43.

[0034] The plate 23 passes through the guide hole 42 and slides with it. The plug housing 10 is at least partially placed inside the cavity 45. The elastic claws 43 are engaged and fixed with the outer wall of the plug housing 10. The key 12 is inserted into the guide groove 41 that matches it and slides with it.

[0035] In the technical solution of the underwater connector test socket with an anti-foolproof mechanism, the elastic claw 43 is engaged and fixed with the outer wall of the plug housing 80, so that the plug housing 80 is fixed in the cavity 45. At the same time, the axial freedom of the locking sleeve 30 is restricted due to the rotational cooperation with the outer wall of the outer shell 20. The plate 23 is inserted into the interior of the guide through hole 42, and the circumferential freedom of the snap ring 40 is restricted. The locking sleeve 30 and the snap ring 40 are threadedly engaged. When the external force drives the locking sleeve 30 to rotate, the snap ring 40 moves linearly along the plate 23 and drives the plug housing 80 to move relative to the outer shell 20.

[0036] Among them, when the snap ring 40 is assembled to the shell 20, the plate 23 is first inserted into the guide hole 42, and the snap ring 40 is moved in the axial direction on the plate 23 until the snap ring 40 and the locking sleeve 30 are initially threaded together. During this process, the plate 23 passes through the guide hole 42 and slides with it; when the plug housing 10 is assembled to the snap ring 40, the plug housing 10 is first initially inserted into the interior of the cavity 45, and then the elastic claw 43 is engaged and fixed with the outer wall of the plug housing 80. During this process, the convex key 12 is inserted into the interior of the guide groove 41 that matches it and slides with it.

[0037] In the present technical solution, the plate 23 passes through the guide through hole 42 and slides with it to form an anti-fool mechanism between the snap ring 40 and the shell 20. When the snap ring 40 is assembled to the shell 20, the snap ring 40 is guided to ensure that the circumferential position between the two is fixed; the convex key 12 is inserted into the guide groove 41 adapted to it and slides with it to form an anti-fool mechanism between the snap ring 40 and the plug housing 10. When the plug housing 10 is assembled into the snap ring 40, the plug housing 10 is guided to ensure that the circumferential position between the two is fixed; at the same time, the convex key 12 is inserted into the guide groove 41, which can prevent the plug from rotating when the plug is assembled into the snap ring 40 and during the process of docking the plug with the socket.

[0038] In the technical solution of the underwater connector test socket with a foolproof mechanism, dual foolproof mechanisms between the snap ring 40 and the housing 20 and between the snap ring 40 and the plug housing 10 are used to guide the test socket, the snap ring 40, and the plug under test during assembly, so that the positions of the test socket, the snap ring 40, and the plug under test are unique, ensuring a one-to-one correspondence between the internal hole positions of the test socket and the plug under test.

[0039] More specifically, in order to achieve foolproof operation between the snap ring 40 and the housing 20, in this embodiment, as shown in FIG. Figure 5 、 Figure 6 、 Figure 7As shown, multiple plates 21 are provided, each having different widths, and are circumferentially distributed around the plug-in end of the housing 20. The number of guide holes 42 matches the number of plates 23, and the guide holes 42 match the plates 23. When the snap ring 40 is assembled to the housing 20, the multiple plates 23 are inserted into the corresponding guide holes 42.

[0040] As another embodiment, in order to save more cost, the plate 21 can also be reduced to one, and the number of the guide holes 42 and the plate 23 can be set to be consistent, and the guide holes 42 are matched with the plate 23; when the retaining ring 40 and the housing 20 are assembled, the plate 21 is inserted into the inside of the guide hole 42 to limit the relative position of the retaining ring 40 and the housing 20 in the circumferential direction.

[0041] In order to improve the convenience of inserting the plate 21 into the guide hole 42, as shown in FIG. Figure 6 As shown, the plug-in end of the plate 21 is provided with a chamfer.

[0042] In this embodiment, the plug groove 81 is provided on the plug housing 80, and the positioning boss 44 is provided on the elastic claw 43, which is mainly manifested as follows. Figure 2 、 Figure 3 、 Figure 7 As shown, at least one plug groove 11 is provided on the outer wall of the plug housing 10 , and a positioning boss 44 matching the plug groove 11 is provided on the end surface opposite to the elastic claw 43 .

[0043] When there is one plug groove 81, the plug groove 81 is distributed in a ring shape on the plug housing 80, and multiple positioning bosses 44 cooperate with the same plug groove 81; when there are multiple plug grooves 81, multiple plug grooves 81 are distributed circumferentially on the plug housing 80, and multiple positioning bosses 44 respectively cooperate with multiple plug grooves 81.

[0044] As another embodiment, the plug groove 81 can also be set on the elastic claw 43, and the positioning boss 44 can be set on the plug housing 80. It is mainly manifested in that at least one positioning boss 44 is set on the outer wall of the plug housing 10, and a plug groove 11 matching the positioning boss 44 is set on the opposite end face of the elastic claw 43.

[0045] When there is one positioning boss 44, the positioning boss 44 is distributed in a ring shape on the plug housing 80, and multiple plug grooves 81 cooperate with the same positioning boss 44; when there are multiple positioning bosses 44, multiple positioning bosses 44 are distributed circumferentially on the plug housing 80, and multiple positioning bosses 44 respectively cooperate with multiple plug grooves 81.

[0046] In the present technical solution, the setting of the positioning boss 44 and the plug groove 81 realizes the requirement of the plug housing 80 and the retaining ring 40 being engaged and fixed. When the socket and the plug are matched, the plug housing 80 is inserted into the cavity 45. At this time, the positioning boss 44 is located inside the plug groove 81, which limits the axial freedom of the plug housing 80, that is, the plug housing 80 cannot undergo axial displacement inside the retaining ring 40, thereby realizing the setting of driving the plug to move linearly in the axial direction by rotating the locking sleeve 30.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
