[0017] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0018] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] The present invention provides a four-coaxial sintered sealed watertight connector, comprising a four-coaxial sintered socket and a watertight plug. Figure 1 As shown, the watertight plug consists of a plug housing 1, a jack insulator assembly 2, a jack assembly 3, a first differential jack assembly 4, a first O-ring 5, a connecting nut 6, a first fixing claw 7, a parallel coil spring 8, a sealing ring assembly 9 and a tail pipe 10.

[0020] This invention is suitable for medium-depth underwater operations and can simultaneously transmit differential signals and low-frequency electrical signals. The quad-coaxial sintered sealed watertight connector consists of a quad-coaxial sintered socket and a watertight plug, which are threaded together for a reliable connection. The connector is also marine-resistant and can withstand long-term use in corrosive marine environments.

[0021] Among them, the jack insulator assembly 2 cooperates with the positioning key slot of the plug shell 1 through the positioning key to achieve circumferential anti-rotation, and is axially fixed by adhesive; the first fixing claw 7 is stuck in the internal ring groove of the plug shell 1 to axially fix the jack insulator assembly 2; the first O-ring 5 is installed in the external ring groove of the plug shell 1; the parallel coil spring 8 is stuck in the external ring groove of the plug shell 1 to axially fix the connecting nut 6; the jack assembly 3 and the first differential jack assembly 4 are sent into the jack insulator assembly 2 using a picking and delivering operation, and the first differential jack assembly 4 is protected by a sealing ring assembly 9 after wiring; the tail pipe 10 is installed at the tail of the plug shell 1 by threads, and vulcanization grooves are left on the outer surfaces of the tail pipe 10 and the plug shell 1 to facilitate vulcanization treatment.

[0022] like Figure 2 As shown, the quad-coaxial sintered socket mainly consists of a glass sintered component 11, a sealing ring 12, a jack insulator component 13, a second O-ring 14, a third O-ring 15, a jack component 16, a second differential jack component 17, a fixing claw 18 and a sealing tube component 19.

[0023] The present invention adopts a glass sintering structure for signal transfer, which solves the problem that the four-coaxial socket cannot be axially watertight, improves the overall sealing performance of the socket, and the axial hydrostatic pressure index of the socket is not less than 6.15MPa; at the same time, it takes into account the differential signal transmission performance and allows the transmission of gigabit network signals.

[0024] like Figure 3 As shown, the glass frit assembly 11 is mainly composed of a socket housing 11-1, pins 11-2, a glass insulator 11-3 and differential pins 11-4.

[0025] The present invention proposes a double-layer combined sintering sealing structure for differential pins, which solves the problem that differential pins cannot be glass-sintered. When the internal and external pressure is 101 kPa, the leakage rate index is no more than 1×10 -8 Pa·m 3 / s.

[0026] Among them, the sealing ring 12 is installed in the internal ring groove of the socket shell 11-1; the jack insulator assembly 13 cooperates with the positioning key groove of the socket shell 11-1 through the positioning key to achieve circumferential anti-rotation, and is axially fixed by adhesive; the fixing claw 18 is stuck in the internal ring groove of the socket shell 11-1 to fix the jack insulator assembly 13 axially; the second O-ring 14 and the third O-ring 15 are installed in the external ring groove of the socket shell 11-1; the jack assembly 16 and the second differential jack assembly 17 are sent into the jack insulator assembly 13 using a picking and sending operation, and the second differential jack assembly 17 is protected by the sealing ring assembly 19 after wiring; the differential pin 11-4 does not affect the signal transmission performance after glass sintering.

[0027] The embodiment of the present invention provides a tail end contact body anti-rotation positioning and guiding structure, which ensures that the needle and hole contact bodies have completed anti-rotation positioning and started guiding docking before they start contacting, thereby ensuring the assembly accuracy of the needle and hole contact bodies.

[0028] It should be noted that the threaded connection between the quad-coaxial sintered socket and the watertight plug in this embodiment of the present invention provides both longitudinal and radial seals when engaged. These seals are achieved by O-rings installed in the grooves of the plug housing 1 and sealing rings installed on the mating surface of the socket. When the quad-coaxial sintered socket and the watertight plug are properly mated, the O-rings and sealing rings are compressed appropriately between the plug housing 1 and the socket housing 11-1, achieving a seal with a hydrostatic pressure of no less than 6.15 MPa.

[0029] Furthermore, the materials used for the quad-coaxial sintered socket and watertight plug are marine-resistant. The external structural components are machined to provide support and protection. Made of high-quality stainless steel with a passivated surface treatment, this material offers excellent corrosion resistance, particularly pitting resistance, and good room-temperature mechanical properties, along with sufficient strength and toughness. This ensures the circular electrical connector operates properly in a marine atmosphere characterized by high temperatures, high salt spray, and mildew, while enduring the combined effects of wind, waves, salt spray, and humidity found in diverse sea areas, as well as temperature fluctuations in varying airspaces, sunlight, rain, snow, and high electromagnetic radiation.

[0030] The above description is merely a specific embodiment of the present invention and should not be construed as limiting the scope of the invention. Therefore, substitutions of equivalent components, or equivalent changes and modifications made within the scope of patent protection, should still fall within the scope of this patent. Furthermore, the technical features of the present invention may be freely combined with one another, with other technical solutions, and with other technical solutions.
