Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a deep-water connector. Background Art

[0002] Connectors refer to all connection components and their accessories used in electronic signals and power supplies. From the perspective of electronic assembly, connectors are plug-in parts that can be disengaged or replaced. In other words, connectors are bridges between all signals. Their quality not only affects the reliability of current and signal transmission, but also affects the quality of the entire electronics and its operation. As the second largest pillar industry of electronic components, connector manufacturing industry produces functional components with electrical connection characteristics. Its main function is to play the role of electrical connection and signal transmission between devices and components, components and cabinets, systems and subsystems. It is one of the essential basic components for the electrical connection of the entire circuit system. Today, connectors have been widely used in aerospace, military equipment, communications, computers, automobiles, industry, household appliances and other fields.

[0003] As human beings accelerate the pace of ocean exploration and development, underwater electrical equipment and devices are widely used. At this time, connectors are needed to connect underwater electrical equipment with surface terminal equipment or power supplies. In addition, for deep water environments, connectors need to have good waterproof properties to prevent water from entering the equipment room and burning the equipment, causing the signal to be frequently disconnected during ground testing. At present, conventional deep-water connectors use a threaded anti-loosening mechanism to connect the plug and the socket together through a threaded connection. However, during long-term use in deep water environments, it is inevitable that water will penetrate through the gap between the plug and the socket, causing water to flow into the connector and burn the equipment.

[0004] With respect to the above-mentioned related technologies, there is a problem that water may penetrate through the connection between the plug and the socket. Summary of the invention

[0005] In order to alleviate the problem of water infiltration through the connection between the plug and the socket, the present application provides a deep water connector.

[0006] A deepwater connector provided in the present application adopts the following technical solution: a deepwater connector, comprising a plug mechanism and a socket mechanism, wherein the plug mechanism is threadedly matched with the socket mechanism, and a first waterproof gasket is provided at the threaded matching position of the plug mechanism for preventing water from penetrating.

[0007] By adopting the above technical solution, a first waterproof gasket is provided at the threaded joint between the plug mechanism and the socket mechanism. When the plug mechanism and the socket mechanism are threadedly mated, the presence of the first waterproof gasket inside can prevent water from penetrating into the interior of the connector, thereby alleviating the problem of water penetrating through the connection between the plug and the socket.

[0019] By adopting the above technical solution, a third waterproof gasket is provided at the tail of the insertion part. If water penetrates from the connection between the plug mechanism and the socket mechanism and passes through the first waterproof gasket, the setting of the third waterproof gasket will prevent water from entering the interior of the connector, thereby enhancing the airtightness of the connector.

[0028] 2. Before the plug nut and the socket housing are threadedly engaged, the end cover clamping ring and the external water retaining ring are in a separated state. When the plug nut is rotated to drive the plug housing close to the socket housing, when the distance from the second waterproof gasket to the end cover clamping ring is smaller than the distance from the external water retaining ring to the end cover clamping ring, the external water retaining ring is threadedly engaged with the end cover clamping ring, and the end cover waterproof ring is clamped between the external water retaining ring and the end cover clamping ring to achieve waterproof sealing. At this time, continue to rotate the plug nut, and the guide bevel on the push member gradually abuts against the support ring.

The plug mechanism 11 is threadedly matched with the socket mechanism 2. The threaded tail end of the plug mechanism 11 is sealed with a first waterproof gasket 119 for preventing water from penetrating.

[0039] A first waterproof gasket 119 is provided at the threaded engagement position of the plug mechanism 11 with the socket mechanism 2. When the plug mechanism 11 is threadedly engaged with the socket mechanism 2, the presence of the first waterproof gasket 119 inside can prevent water from penetrating into the interior of the connector, thereby alleviating the problem of water penetrating through the connection between the plug and the socket.

[0040] For details, please refer to the attached Figure 2 and attached Figure 3 As shown, the plug mechanism 11 includes a plug housing 111 and a plug nut 112. The plug housing 111 and the socket housing 21 are both columnar as a whole, and a circle of raised first blocking ring 1113 is arranged on the outer periphery of the plug housing 111, and a circle of second blocking ring 1121 abutting against the first blocking ring 1113 is arranged on the inner wall of the plug nut 112. After the plug nut 112 is inserted from the left end of the plug housing 111, the first blocking ring 1113 and the second blocking ring 1121 abut against the left side of the first blocking ring 1113, so that the plug nut 112 abuts against the outer periphery of the plug housing 111, and the socket housing 21 is threadedly matched with the plug nut 112, so that the plug mechanism 11 and the socket mechanism 2 are fixedly connected together.

[0041] Refer to the attached Figure 5 As shown, an end cover clamping ring 113 is welded to the outer periphery of the plug nut 112, an end cover waterproof ring 114 is provided on the side of the end cover clamping ring 113 facing the socket housing 21, an external water retaining ring 115 is provided on the side of the end cover waterproof ring 114 facing the socket housing 21, an external water retaining ring 115 is extended away from the inner wall of the external water retaining ring 115 with an external water retaining ring 116, a plurality of bolts are evenly arranged on the circumference of the end cover clamping ring 113, and the end cover clamping ring 113 passes through the end cover waterproof ring 114 and is bolted to the external water retaining ring 115.

[0042] Refer to the attached Figure 5 and attached Figure 6 As shown, a pusher 117 is hingedly connected to the circumference of one side of the end cover clamping ring 113 toward the external water retaining ring 115. The pusher 117 is rod-shaped as a whole. The pusher 117 can move toward or away from the center of the external water retaining ring 115 with the hinge seat as a fixed point. Four pushers 117 are evenly arranged on the inner side of the end cover clamping ring 113. Limiting plates 1173 are arranged on both sides of the hinged movement direction of each pusher 117 to prevent the hinged member from swinging significantly. A guide bevel 1171 is arranged on the side of the end of the pusher 117 away from the end cover clamping ring 113 toward the center of the end cover clamping ring 113. The socket mechanism 2 includes a socket housing 21, and an annular fixing ring 22 is arranged on the outer periphery of the socket housing 21 near the connection between the socket housing 21 and the plug nut 112. A support ring 23 and a second waterproof gasket 25 are arranged on the fixing ring 22. The second waterproof gasket 25 is located on the side of the support ring 23 away from the end cover clamping ring 113. The support ring 23 can abut against the inclined surface of the guide bevel 1171. In the process of threaded engagement between the plug nut 112 and the socket housing 21, the end of the pushing member 117 can abut against the second waterproof gasket 25 and push the second waterproof gasket 25 to move. When the plug nut 112 and the socket housing 21 are completely threadedly engaged, the second waterproof gasket 25 can abut against the external water retaining ring 116 to achieve the sealing of the connector.

[0043] Refer to the attached Figure 1 and attached Figure 2 As shown, the plug housing 111 includes an insertion portion 1111, which is located at one end of the plug housing 111 inserted into the socket housing 21. The inner diameter of the insertion portion 1111 is smaller than the inner diameter of the rest of the plug housing 111. A third waterproof gasket 1112 is provided at the rear end of the insertion portion 1111 for waterproofing.

[0044] Refer to the attached Figure 1 and attached Figure 2 As shown, the inside of the plug housing 111 is successively installed with a tail cap 121, a wire clamp 122 for wiring, a shielding pressure ring 124 for enhancing the anti-interference ability of the connector, an insulator fixing sleeve 120 and a pin insulator assembly 118 from the tail end away from the socket mechanism 2 to the end inserted into the socket mechanism 2. The pin insulator assembly 118 includes a pin 1181 and a pin seat 1182. The pin 1181 is inserted and fixed in the pin seat 1182, and the insulator fixing sleeve 120 is sleeved on the outside of the pin insulator assembly 118.

[0045] Refer to the attached Figure 2 and attached Figure 6 As shown, the socket mechanism 2 also includes a hole insulator assembly 24, a grounding spring 26 and a hexagonal nut 27. The hole insulator assembly 24 is installed inside the socket housing 21. The hole insulator assembly 24 includes a plug hole 241 and a plug hole seat 242. The plug hole 241 is provided on the plug hole seat 242. The hole insulator assembly 24 cooperates with the pin insulator assembly 118, and the pin 1181 cooperates with the plug hole 241 one by one. The grounding spring 26 is arranged between the hole insulator assembly 24 and the socket housing 21 to fix the hole insulator assembly 24 inside the socket housing 21. The hexagonal nut 27 is arranged outside the socket housing 21 and is threadedly matched with the socket housing 21 to connect the connector to the outside.

[0046] Refer to the attached Figure 2 and attached Figure 6As shown, a snap-in convex ring 11821 is provided on the outer periphery of the pin seat 1182, and a snap-in concave ring 1201 matching with the snap-in convex ring 11821 is provided on the inner wall of the insulator fixing sleeve 120. The snap-in convex ring 11821 and the snap-in concave ring 1201 are snap-in with each other to prevent the pin insulator assembly 118 from rotating in the insulator fixing sleeve 120 and failing to match with the hole insulator assembly 24. The insertion portion 1111 is provided with a snap-in boss 1202, and a snap-in groove 211 is provided on the inner wall of the socket housing 21 to snap-in with the snap-in boss 1202. The snap-in boss 1202 and the snap-in groove 211 are snap-in with each other to ensure that each pin 1181 matches with the corresponding jack 241, thereby ensuring the normal connection of the connector. A fourth waterproof gasket 123 is provided between the wire clamp 122 and the shielding pressure ring 124 to prevent water from entering the insulator fixing sleeve 120 and improve the waterproof performance of the connector. The tail cap 121 is threadably matched with the tail end of the plug housing 111 to fix the parts inside the plug housing 111 .

[0047] The implementation principle of a deep-water connector in the embodiment of the present application is as follows: before the plug nut 112 is threadedly engaged with the socket housing 21, the end cover clamping ring 113 and the external water retaining ring 115 are in a separated state. When the plug nut 112 is threadedly engaged with the socket housing 21, the plug nut 112 is rotated so that the plug nut 112 drives the plug housing 111 close to the socket housing 21. When the distance from the second waterproof gasket 25 to the end cover clamping ring 113 is less than the distance from the external water retaining ring 116 to the end cover clamping ring 113, the external water retaining ring 115 is threadedly engaged with the end cover clamping ring 113, and the end cover waterproof ring 114 is clamped between the external water retaining ring 115 and the end cover clamping ring 113 to achieve waterproof sealing. At this time, continue to rotate the plug nut 112, and the guide bevel 1171 on the push member 117 gradually abuts against the support ring 23. During the abutment between the guide bevel 1171 and the support ring 23, the support ring 23 gradually lifts the push member 117 so that the end of the push member 117 abuts against the second waterproof gasket 25, and because the push member 117 is being lifted, it will push the second waterproof gasket 25 to move away from the plug nut 112. When the plug nut 112 and the socket housing 21 are fully threadedly connected, the second waterproof gasket 25 is at the edge of the fixing ring 22 and tightly abuts against the external water retaining ring 116, thereby achieving the sealing of the connector, which can reduce the entry of water into the threaded connection between the plug nut 112 and the socket housing 21, causing the thread rust at the connection between the plug nut 112 and the socket housing 21 or water to enter the inside of the connector. The plug mechanism 11 is provided with a sealing sleeve and a first waterproof gasket 119 at the end of the threaded mating part with the socket mechanism 2. When the plug mechanism 11 is threadedly mated with the socket mechanism 2, due to the presence of the first waterproof gasket 119 inside, even if water penetrates into the connector through the threaded connection between the plug nut 112 and the socket housing 21, the first waterproof gasket 119 can effectively block it. If water still passes through the first waterproof gasket 119, the third waterproof gasket 1112 provided at the end of the insertion part 1111 can further block the water.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
