[0039] Example 1

[0040] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0041] Please refer to Figures 1 to 5As shown, an optoelectronic hybrid watertight connector comprises: a plug assembly, comprising a first shell made of stainless steel, a first insulating seat 103 made of PPS or PEK is sealed in the first shell, and the above-mentioned socket assembly comprises a second shell made of stainless steel, a second insulating seat 206 made of PPS or PEK is sealed in the second shell; since PS (polyphenylene sulfide) and PEK (polyether ketone) are two high-performance engineering plastics, both have excellent high temperature resistance and can be used for a long time in a high temperature environment without failure, the heat deformation temperature of PPS is about 200°C, and the heat deformation temperature of PEK is higher, about 250°C to 300°C. In this application, PEK material is preferably used as the material of the insulating seat, and the above-mentioned PEK (polyether ketone) can also be replaced by PEEK (polyether ether ketone) with similar performance.

The present application can preferably use 316L stainless steel. The first insulating seat 103 and the second insulating seat 206 are provided with an even number of interconnected optical fiber connection assemblies and metal connectors that can be connected to each other. Since optical signals need to be transmitted in both directions, an even number of optical fiber connection assemblies are used to support the bidirectional transmission of signals, and multiple metal connectors that can be connected to each other. Through multiple metal connectors, electrical signals can be transmitted or power can be supplied to the equipment to form a power supply loop or an electrical signal loop.

The above-mentioned ceramic tube 112 can form a good protection for the above-mentioned optical fiber connection core to avoid overheating of the connector and deformation or damage of the optical fiber connector; the material of the metal connector and its preset diameter enable it to adapt to the preset voltage threshold and current threshold and the contact resistance is not greater than 0.2mΩ; a connecting nut for connecting to the second shell is provided on the outside of the first shell; wherein, when the plug assembly is connected to the socket assembly, a seal is formed at the connection position.

[0045] The corresponding second housing 205 is provided with threads. When connected, the connecting nut 106 is connected and fastened with the threads on the second housing 205. Moreover, since the first insulating seat 103 is sealed and connected with the first housing, each connecting pin can withstand a high voltage of 2000V and a large current of 50A. An even number of optical fibers are also provided in the connector to enable it to transmit electrical signals and optical signals simultaneously, solving the problem that the current connector can only support electrical connection and has a single function. The first insulating seat 103 is provided with at least one first pin 101 and at least one first hole 102 to enable it to It supports large current loops, and by setting the pins and sockets in the same plug, the corresponding sockets are provided with matching sockets and pins, so that it can directly replace the fool-proof design, and there is no need to design a fool-proof structure for it. The pins in the plug can be aligned with the sockets in the socket, otherwise the connection cannot be made. In addition, the length of the pin can be designed to be slightly longer than the above-mentioned fiber optic pin connector assembly. When the pin is correctly inserted into the socket, it can also guide the connection of the fiber optic pin connector assembly, ensure the precise docking of the fiber optic pin connector assembly, and protect it from colliding with other protruding positions, causing deformation or damage that affects its use.

[0046] In this embodiment, compared with traditional connectors that generally only support voltages below 1,000 volts and current transmissions below 10 amperes, the above-mentioned optoelectronic hybrid watertight connector of the present application can support voltages up to 2,000 V and current transmissions of 50 A by designing the coordination of each pin and each socket, thereby greatly improving its electrical performance. It can also solve the problems of insufficient pressure resistance and poor watertightness of traditional connectors when used in special environments such as underwater. The above-mentioned optoelectronic hybrid watertight connector adopts a sealing design and forms a sealing position between the plug assembly and the socket assembly, thereby effectively improving the pressure resistance and watertightness and ensuring reliability in harsh environments.

[0047] It should be noted that the above-mentioned pins can withstand a high voltage of 2000V and a large current of 50A. The above-mentioned pins can be made of copper alloy materials with a larger diameter and plated with precious metals on the surface, which can not only improve their high temperature resistance and oxidation resistance, but also improve their stability. For example, copper or copper alloy pins with a diameter of 4.9 to 5mm can be used, and pure gold can be plated on the surface.

[0048] Example 2

[0049] A photoelectric hybrid watertight connector, wherein Figure 1As shown, the first housing includes a plug housing 107, a wire cover 108, a first wire locking sleeve 109, and a second wire locking sleeve 110; the first insulating seat 103 is sealed and arranged in the plug housing 107; one end of the wire cover 108 is connected to the first insulating seat 103, and the other end is connected to one end of the first wire locking sleeve 109; the second wire locking sleeve 110 is arranged at the other end of the first wire locking sleeve 109, and partially fits and extends to the inner circle of the first wire locking sleeve 109.

At the same time, the first locking wire sleeve 109 and the second locking wire sleeve 110 lock the cable or its inner lining.

[0050] Further preferably, a locking nut 111 for locking the cable is provided inside the plug housing 107 and at the end of the second locking wire sleeve 110. The locking nut 111 can be locked on the outer skin of the cable, so that the cable is connected to the above-mentioned plug assembly more tightly and firmly. A vulcanized 3M colloid 115 is provided at the tail end of the outside of the above-mentioned plug housing 107; a first epoxy sealant 114 for sealing is provided in the gap between the position where the plug housing 107 is connected to the vulcanized 3M colloid 115 and the cable, so that the connection between the cable and the connector has better air tightness and water tightness; when used for underwater operations, the problem of insufficient sealing can be effectively avoided. Through the above-mentioned structure, it can withstand underwater pressure of up to 10MPa. For example, it can be applied to deep-water robots, and the socket end of the cable is arranged on the robot, which is sealed and fixed by a plug assembly, and is used for power supply through the electrical connection of the pin and the socket. By supporting high voltage and large current, the electric energy it can transmit can meet the needs of underwater operations. At the same time, the signal is transmitted through the optical fiber. Since the optical fiber has the advantages of stable signal, long transmission distance and no interference from electrical signals, the stability of the signal can be ensured, so as to precisely control the underwater robot.

[0051] It should be noted that since the equipment in deep water areas needs to withstand greater pressure, it needs sufficient power to resist the water pressure during operation, and other operation outputs are also required to power the underwater equipment, especially deep water equipment which requires greater power. This application increases the voltage tolerance threshold and current tolerance threshold of the connector to enable it to better meet work needs.

[0052] Further preferably, Figure 1As shown, a first sealing ring 104 is also provided at a position opposite to the inner side of the plug housing 107 and the connecting nut 106; when the plug assembly and the socket assembly are connected, the first sealing ring 104 forms a seal with the outer side of the second shell 205, wherein the first sealing ring 104 can be a silicone sealing ring.

The retaining spring 105 is arranged in the slot between the connecting nut 106 and the plug housing 107 to prevent the connecting nut 106 from falling off from the plug housing 107.

[0054] Further preferably, the gap between the second shell 205 and the second insulating seat 206 is filled with a second epoxy sealant 209. For example, epoxy sealant can be poured into the gap between the second shell 205 and the second insulating seat 206 for sealing, and the second epoxy sealant 209 is formed after it dries, so that it forms a seal at the tail of the socket assembly.

[0055] Further preferably, the second jack 201 and the second pin 203 are connected to the wire at the end thereof and are also sleeved with a first heat shrink tube 207, and the second fiber optic pin assembly 202 is connected to the fiber at the end thereof and is also sleeved with a fiber optic heat shrink tube 208; the second housing 205 is provided with a ring groove at its end, and a second sealing ring 204 is provided in the ring groove. By covering the connection position of the optical fiber and the second fiber optic assembly 202, and the connection position of the second jack 201 and the second pin 203 at the end thereof and the wire, the connection position can be protected from external environment damage, such as moisture, dust, chemical liquid, etc. This helps to extend the service life of the optical fiber or wire, while reducing the frequency of maintenance and replacement. On the other hand, the heat shrink tube has a certain insulation performance, which can effectively isolate the optical fiber or wire at the connection position to prevent electrical failure or signal interference caused by external reasons; on the other hand, the heat shrink tube has a certain flexibility, which can effectively fix the optical fiber or wire at the connection position to avoid accidental pulling or vibration causing unstable connection or breakage.
