Description

Technical Field

[0001] The invention relates to the field of electrical equipment, in particular to a marine electrical connector. Background Art

[0002] An electrical connector, also known as a connector, joint or socket, is a device used to connect two active devices. Its main function is to transmit current or signals. It is usually composed of a male end and a female end. It can transmit electrical signals or currents through contact. Connectors play a vital role in electrical systems. They can establish a bridge of communication between disconnected or isolated parts of the circuit to ensure the flow of current, thereby realizing the predetermined function of the circuit. In the electrical system of a ship, electrical connectors are an indispensable part, ensuring the stable connection between various electrical components inside the ship.

[0003] Since ships are on the water for a long time, the humidity inside the ships is heavy. The electrical connectors used in ships need to have a certain moisture-proof ability to prevent short circuits caused by moisture. The existing Chinese public patent document: CN214068973U discloses a connector with a waterproof function. The plug part can be effectively protected by the outer cover. The panel of the outer cover can be embedded in the embedding groove of the connecting seat to achieve a close connection between the outer cover and the connecting seat. The gap between the outer cover and the connecting seat is reduced by a sealing ring, which can effectively prevent external water from invading the interior; at the same time, the wire harness can be wrapped by a rubber sealing sleeve to reduce the gap between the wire harness and the overall structure, and prevent water from entering the interior through the gap of the wire harness. Although the sealing ring can provide protection for the connecting end of the electrical connector, since the sealing ring is made of rubber, the humidity on the ship is heavy, which will accelerate the aging speed of the rubber, speed up the replacement cycle of the sealing ring, and reduce the sealing between the plug and the socket.

The outer side of the sleeve plate 16 is provided with a long groove for limiting the sliding of the pressure rod 13, and the pressure rod 13 is slidably installed in the long groove of the sleeve plate 16. A clamping strip 17 is fixedly installed at one end of the positioning plate 14 away from the sleeve plate 16, and a sleeve frame 18 is fixedly installed on the outer side of the socket 1. A clamping hole for inserting the positioning plate 14 is provided on the outer side of the sleeve frame 18. The height of the clamping hole is greater than the sum of the heights of the clamping strip 17 and the positioning plate 14. A plurality of equally distributed support rods 28 are fixedly installed at the bottom of the L-shaped plate 12, and a slot for limiting the insertion of the support rod 28 is provided in the sliding cavity of the protective shell 5;

[0034] When the protective shell 5 is sleeved on the outer side of the protective shell 3, the two positioning plates 14 on the protective shell 5 can be inserted into the card holes of the sleeve frame 18. When the air in the annular airbag 6 is reduced, the resilience of the tension spring 11 is used to pull the slider 10 to move, so that the slider 10 pulls the pressure strip 8 through the slide rod 9 to squeeze the annular airbag 6, so that the annular airbag 6 maintains the sealing of the protective shell 3. At the same time, the pressure strip 8 drives the L-shaped plate 12 to move along the sliding cavity of the protective shell 5, so that the L-shaped plate 12 drives the pressure rod 13 to move along the long groove on the sleeve plate 16, and pushes the sleeve plate 16 to move downward. The sleeve plate 16 drives the positioning plate 14 to swing outward with the positioning rod 15 as the fulcrum, so that the card strip 17 on the positioning plate 14 can be against the outer side of the sleeve frame 18, preventing the protective shell 5 from falling off from the plug 2, and it is convenient for the staff to determine whether the annular airbag 6 is leaking according to the swing of the positioning plate 14, so as to replenish the air in time, thereby achieving the effect of safe anti-falling and convenient maintenance.

[0035] Working principle: First, the staff holds the anti-skid pad 26 on the outside of the protective shell 5, puts the inner side of the protective shell 5 on the outer side of the protective sleeve 3, and inserts the plug 2 into the inner side of the protective sleeve 3, pushes the protective shell 5 to move, so that the plug 2 and the socket 1 are docked. At this time, the annular airbag 6 on the inner side of the protective shell 5 contacts the outer side of the protective sleeve 3, and the two positioning plates 14 on the protective shell 5 are inserted into the card holes of the sleeve frame 18. Then, the staff opens the air injection valve 7 and injects air into the annular airbag 6 through the air injection valve 7, so that the annular airbag 6 is pressed between the protective shell 5 and the protective sleeve 3. The annular airbag 6 improves the sealing between the protective sleeve 3 and the protective shell 5, thereby improving the sealing between the plug 2 and the socket 1, preventing moisture on the ship from entering between the plug 2 and the socket 1. At the same time, the annular airbag 6 pushes the two pressure strips 8 to move synchronously. The pressure strip 8 pulls the slider 10 along the slide groove inside the protective shell 5 through the slide rod 9, so that the slider 10 stretches the tension spring 11. When the air in the annular airbag 6 is reduced, the pressure of the annular airbag 6 on the pressure strip 8 is reduced, and the slider 10 is pulled to move by the resilience of the tension spring 11, so that the slider 10 drives the slide rod 9 along the slide groove. As the protective shell 5 moves in the slide groove, the slide bar 9 can pull the pressure strip 8 to squeeze the annular airbag 6, so that the contact surface between the annular airbag 6 and the pressure strip 8 is squeezed and deformed, thereby preventing a gap between the annular airbag 6 and the protective sleeve 3, and maintaining the sealing of the annular airbag 6 to the protective sleeve 3. At the same time, the pressure strip 8 drives the L-shaped plate 12 to move synchronously along the slide cavity of the protective shell 5, so that the L-shaped plate 12 drives the pressure rod 13 to move along the long groove on the sleeve plate 16, and the pressure rod 13 can push the sleeve plate 16 to move downward, and the sleeve plate 16 drives the positioning plate 14 to move along the sleeve frame 1 with the positioning rod 15 as the fulcrum. 8 is swung in the card hole, so that the card strip 17 on the positioning plate 14 can be against the outside of the sleeve frame 18, thereby locking the sleeve frame 18, and then locking the protective shell 5 on the sleeve frame 18, preventing the protective shell 5 from falling off from the protective sleeve 3, thereby locking the socket 1 and the plug 2. In addition, when inspecting, the staff can judge whether the annular airbag 6 is leaking by the swing of the positioning plate 14, which is convenient for timely replenishing the annular airbag 6 and improving the convenience of later maintenance, thereby achieving the effect of sealing and moisture-proofing, and improving the safety of the socket 1 and the plug 2.
