To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.

Referring to fig. 1, 2 and 3, the inventor provides a sealed underwater rectangular electrical connector. The electrical connector is composed of a plug module 1 and a receptacle module 2. Further, the plug module 1 may be composed of a plug incoming line 11, a plug first housing 13, a plug second housing 12, a hydraulic channel 14, a diaphragm spring 15, a piston first seal ring 16, a plug magnetic pole 17, a plug male 18, a diaphragm spring 19, a swash block piston 20, a plug wire 21, a plug 22, and the like. The socket module 2 is composed of a female plug 3, a socket magnetic pole 4, a reed 5, a socket lead 6, an electric brush 7, a first socket shell 8, a second socket shell 9, a socket incoming line 10 and the like, and the plug module 1 and the socket module 2 can be mechanically fastened through the female plug 3 and a male plug 18.

As a preferred structure of the present invention, the plug first housing 13 and the plug second housing 12 are assembled together by a screw structure and form a hollow cavity inside thereof. The hollow interior of the plug second housing 12 is used for the plug inlet line 11 to pass through, and the plug inlet line 11 is further electrically connected to the plug 22 via the plug wire 21. In addition, an upper cavity, a lower cavity and a hydraulic channel 14 are arranged inside the first plug housing 13, the hydraulic channel 14 is filled with sealed hydraulic oil, the upper cavity is in sealing fit with a left piston of the swash block piston through a first piston sealing ring 16 and is communicated with the lower cavity through the hydraulic channel 14, the lower cavity is in sealing fit with the plug 21, and the plug 21 can axially move relative to the first plug housing 13. The diaphragm spring 19 is arranged between the left-hand piston of the swash block piston 15 and the upper chamber of the first plug housing 13, which first plug housing 13 is provided on the plug-in end face side with a plurality of plug poles 17 and several small recesses for the circumferential positioning of the ball spring assembly 22 fitted with the small holes provided on the swash block piston 15.

Likewise, the first receptacle housing 8 and the second receptacle housing 9 of the receptacle module 2 are both hollow dielectric materials and are assembled together by a threaded arrangement. The hollow interior of the second housing 9 of the socket is used for passing through a socket inlet wire 10, and the socket inlet wire 10 is electrically connected with the tongue-shaped plates 5 through the socket lead wires 6. In addition, a groove for installing the brush 7 is arranged in the first socket shell 8, and the brush 7 and the socket inlet wire 11 can move axially relatively but keep an electric connection state. The socket first housing 8 is provided with a plurality of socket poles 3 on the insertion end surface side.

Further, in the case of the double tightening of the primary magnetic locking and the secondary mechanical locking, the plug 22 is in contact with the reed 5, thereby electrically communicating the plug incoming line 11 and the socket incoming line 10, and is insulated from the liquid water outside the connector.

Further, the following will further illustrate the working principle of the underwater electrical connector of the present invention:

(1) when the connector is pulled out: preferably, the operator only needs to take up the plug module 1 and the socket module 2 of the connecting machine with both hands respectively, and further loosens the connection on the connecting machine through the female connector 3 and the male connector 18. In this way the subsea connector will unlock the mechanical lock. Further, under the action of the diaphragm spring 19, the swash block piston 15 will be moved to the right, thereby retracting the lower cavity of the plug first housing 13 to the left in the plug 21 under the negative pressure of the hydraulic oil, while achieving complete separation of the connectors.

(2) During the operation of inserting the connector: an operator firstly grasps and aligns the plug module 1 and the socket module 2 with both hands, and then makes the plug module 1 and the socket module 2 approach each other continuously until the plug magnetic pole 17 and the socket magnetic pole 3 contact each other by overcoming the acting force of the diaphragm spring 19. At this time, the balls on the ball spring assembly 22 are pressed against the corresponding small grooves of the first plug housing 13, and the plug magnetic poles and the socket magnetic poles are installed in a matching way with different magnetic poles, and the mutual magnetic force can overcome the acting force of the diaphragm spring, so that the plug module and the socket module are kept in a magnetic locking state. Since the swash block piston 15 moves leftward and thus the plug 22 moves rightward with respect to the lower cavity of the plug first housing 13 by the hydraulic oil pressure, the connector completes the electrical connection after the plug 22 contacts the reed 5. At this time, the primary magnetic locking is manually completed. Further, after the primary magnetic locking operation is finished, the relative positions of the socket first housing 8 and the plug first housing 13 can be tightly fixed through the mechanical fastening of the female plug 3 and the male plug 18. In addition, due to the self-locking characteristic of the swash block piston 15, the connector can adapt to high-pressure and complex deepwater area operation environment.

It should be noted that, although the above embodiments have been described herein, the invention is not limited thereto. Therefore, based on the innovative concepts of the present invention, the technical solutions of the present invention can be directly or indirectly applied to other related technical fields by making changes and modifications to the embodiments described herein, or by using equivalent structures or equivalent processes performed in the content of the present specification and the attached drawings, which are included in the scope of the present invention.
