Description

Technical Field

[0001] The utility model relates to the field of electric connectors, in particular to an underwater electric connector. Background Art

[0002] A connector is an electromechanical component that connects electrical circuits. Its function is to build a bridge of communication between blocked or isolated circuits within a circuit, so that current can flow and the circuit can achieve its intended function. Underwater electrical connectors are a commonly used device in marine engineering. Faced with the conductivity of underwater liquids in the ocean and the working environment of underwater pressure, underwater pluggable electrical connectors must not only have the conventional performance of ordinary electrical connectors, but also have the ability to adapt to the special working environment of the ocean underwater, so as to achieve convenient, fast, safe and effective connection and separation.

[0003] In a Chinese patent, an electrical connector for underwater work is disclosed, and its patent number is CN214957551U. In the patent, an electrical connector for underwater work includes a socket, the socket is a cone shell structure, the end of the socket is connected to the socket wire end, and the inner side of the other end of the socket is provided with a socket fixing structure; the socket fixing structure is composed of equidistant annularly distributed plug sleeves and a central plug located in the middle. An electrical connector for underwater work uses a cone structure to insert the plug and the plug between the socket and the plug, so that the contact surface is a cone surface, which can effectively prevent liquid from penetrating. The connection is threaded between the tightening ring and the sealing ring, and the gasket pressed on the inner wall of the sealing ring can stably tighten the two ends of the plug and the socket and seal the connection end surface, which can play a stable waterproof structure and improve the sealing of the plug and the socket.

[0004] The above-mentioned published patents have the following disadvantages:

[0005] (1) In the prior art, the waterproof and insulating properties of the connection parts of the electrical connectors used underwater are very good. However, since both ends of the electrical connector need to be used with connecting wires, there is a certain gap between the connecting wires at both ends of the electrical connector and the electrical connector body, resulting in the risk of water ingress during the use of the electrical connector.

[0006] (2) In the prior art, electrical connectors located underwater are generally sealed and waterproofed using sealing rings. However, after being used for a period of time, the sealing rings are in contact with water for a long time, which causes the surface of the sealing rings to age, thereby affecting the waterproof performance of the electrical connectors.

[0007] The technical problem to be solved by the utility model is to overcome the above technical defects and provide an underwater electrical connector.

[0008] In order to solve the above problems, the utility model proposes the following technical solutions:

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 6 As shown, an underwater electrical connector includes a plug 1, a socket 2 is arranged at one end of the plug 1, a connecting groove 202 is arranged at one end of the socket 2 and connected to a connector 3 through a screw ring 1 301, and an insulating pad 1 203 and an insulating pad 2 302 located at one end of the socket 2 and the inner side of the connector 3 protect the plug 1 through their insulating materials, an insulating sleeve 306 located on the inner side of the connector 3 is fixed on the surface of the plug 1 to further protect it, a connecting line 1 4 and a connecting line 2 5 respectively fixed at one end of the plug 1 and the socket 2 facilitate signal transmission, a first protective sleeve 6 located on the outer side of the connector 3 is connected to a second protective sleeve 7 provided with a screw ring 2 702 through a limiting ring 602 at one end thereof, and three sealing rings 8 located at one end of the connector 3, one end of the socket 2 and one end of the second protective sleeve 7 are fixed by a fixing assembly 801, and the fixing assembly 801 is provided with a rotating shaft 811 connected to a fixing plate 812 to limit the sealing ring 8.

[0028] The multiple contacts 101 disposed on the surface of the plug 1 correspond one-to-one to the multiple contact holes 201 on the surface of the socket 2 .

[0029] Through the above technical solution, the one-to-one correspondence between the contacts 101 and the contact holes 201 makes the plug 1 and the socket 2 more tightly connected, facilitating the transmission of signals, power, etc. by the electrical connector, thereby ensuring the normal use of the electrical connector.

[0030] The connecting ring 1 303 inside the connecting member 3 is connected to the connecting ring 2 305 rotating on the surface of one end of the plug 1 through a large spring 304 .

[0031] Through the above technical solution, under the elastic force of the large spring 304, after the connector 3 is threadedly fixed to the socket 2, the elastic force of the large spring 304 is used to enable the plug 1 on the surface of the connecting ring 2 305 to be tightly connected to the socket 2 to prevent the two from being separated during use.

[0032] An isolating ring 1 601 and an isolating ring 2 701 are respectively provided at the connection points between the first protective sleeve 6 and the second protective sleeve 7 and the connecting line 1 4 and the connecting line 2 5 .

[0033] Through the above technical solution, the isolation ring 1 601 and the isolation ring 2 701 can ensure that the connection between the two and the connecting line can be tighter, ensuring that the structure of the electrical connector is more stable when used underwater.

[0034] The insertion rod 813 sliding on the surface of the fixed plate 812 is connected to the stopper 815 through the shift rod 814 , so that the small spring 816 of the stopper 815 can be extended and retracted to control the position of the shift rod 814 .

[0035] Through the above technical solution, under the elastic force of the small spring 816, the stopper 815 can drive the shift rod 814 to extend and retract, ensuring that the insertion rod 813 at one end of the shift rod 814 can move away from the slope at the bottom, thereby facilitating the separation and connection of the fixed plate 812.

[0036] The insertion rod 813 slides on the surface of the insertion rod 813 through a slider 817 at one end, and the bottom end of the insertion rod 813 is clamped through a slope structure.

[0037] Through the above technical solution, under the action of the slider 817, when the bottom end of the plug rod 813 is disengaged, the plug rod 813 can slide up and down, which is convenient for fixing the sealing ring 8 on the inner side of the fixing plate 812.

[0038] During use, when the user uses the underwater electrical connector, the contact 101 on the surface of the plug 1 is inserted into the inner side of the contact hole 201, and the plug 1 is connected to the socket 2 through it. The connecting piece 3 located on the outside of the plug 1 is fixed to the inner side of the connecting groove 202 of the socket 2 through the screw ring 1 301 at one end thereof. During the rotation of the connecting piece 3 through the screw ring 1 301, the large spring 304 between the connecting ring 1 303 and the connecting ring 2 305 is used to ensure that it can squeeze the plug 1 so that it is more stably connected to the socket 2, and the first protective sleeve 6 and the second protective sleeve 7 located on the outside of the connecting piece 3 are connected through the screw ring 2 702 to further protect the electrical connector. At the same time, when the sealing ring 8 used for sealing needs to be replaced, under the elastic force of the small spring 816, the shift rod 814 can assist the insertion rod 813 to move to one side, and under the action of the slider 817, the insertion rod 813 can move upward, so that the fixing plate 812 is opened through the rotating shaft 811, and the inner sealing ring 8 is replaced.
