Description

Technical Field

[0001] The present 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. After contact, it can transmit electrical signals or current. Connectors play a vital role in electrical systems. They can establish a communication bridge between disconnected or isolated parts in the circuit, ensure the flow of current, and thus realize the intended 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 relatively high. The electrical connectors used on 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 outer cover can effectively protect the plug part. 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 narrowed by a sealing ring, which can effectively prevent external water from intruding into 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, thereby preventing water from entering the interior through the gap of the wire harness. Although the sealing ring can provide protection for the connection end of the electrical connector, since the sealing ring is made of rubber, the humidity on the ship is relatively high, which will accelerate the aging rate of the rubber, speed up the replacement cycle of the sealing ring, and reduce the sealing between the plug and the socket.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figures 1-8 The figure shows a marine electrical connector, comprising a socket 1 and a plug 2 arranged on the right side of the socket 1.

A wiring harness 4 is fixedly installed on the side of the plug 2 away from the protective sleeve 3. A protective shell 5 is provided on the outside of the plug 2 to provide protection between the plug 2 and the socket 1. Anti-slip pads 26 are fixedly installed on the top and bottom of the protective shell 5 to facilitate pulling the protective shell 5 to separate and connect the plug 2 and the socket 1; it also includes: a waterproof mechanism for sealing the plug 2 and the protective sleeve 3 against moisture, and the waterproof mechanism is installed on the inner side of the protective shell 5; an anti-slip mechanism for providing anti-slip protection for the plug 2, and the anti-slip mechanism is installed on the inner side of the protective shell 5; a quick-release mechanism for quickly disassembling the plug 2 and the protective shell 5, and the quick-release mechanism is installed on the outer side of the protective shell 5.

[0031] The waterproof mechanism includes an annular airbag 6 arranged on the inner side of the protective shell 5. The inner side of the annular airbag 6 is in contact with the outer side of the protective sleeve 3. The elasticity of the annular airbag 6 is used to improve the sealing performance between the protective sleeve 3 and the socket 1 and the plug 2. The inner side of the protective shell 5 is provided with a cavity for installing the annular airbag 6, which is convenient for positioning the annular airbag 6.

The inner side of the protective shell 5 is provided with a positioning groove for the annular rib 27 to limit the insertion, which is convenient for installing and positioning the annular airbag 6. The outer side of the annular airbag 6 is fixed with an air injection valve 7 extending to the outside of the protective shell 5. , the annular airbag 6 can be injected with air through the air injection valve 7. Two symmetrically distributed pressure strips 8 are slidably installed on the inner side of the cavity of the protective shell 5. A movable groove for the pressure strip 8 to limit the sliding of the pressure strip 8 is opened in the cavity of the protective shell 5. Slide rods 9 are fixedly installed at both ends of the pressure strip 8. A slider 10 is fixedly installed on the end of the slider 9 away from the pressure strip 8. A sliding groove for the sliding rod 9 and the slider 10 to limit the sliding of the protection shell 5 is opened on the inner side of the protection shell 5. A tension spring 11 is fixedly installed between the end of the slider 10 away from the slider 9 and the inner side of the sliding groove of the protection shell 5. By utilizing the elasticity of the tension spring 11, the slider 10 and the slider 9 pull the pressure strip 8 to squeeze the annular airbag 6;

[0032] The plug 2 can move along the inner side of the protective cover 3 and dock with the socket 1. The plug 2 drives the protective shell 5 to move along the outer side of the protective cover 3, so that the annular airbag 6 inside the protective shell 5 moves along the inner side of the protective cover 3. The annular airbag 6 can be wrapped around the outer side of the protective cover 3. The staff can inject air into the annular airbag 6 through the air injection valve 7, so that the annular airbag 6 is against the protective shell 5 and the protective cover 3, thereby improving the sealing between the socket 1 and the plug 2 and preventing moisture on the ship from entering, thereby achieving a sealing and moisture-proof effect.

[0033] The anti-slip mechanism includes an L-shaped plate 12 fixedly mounted on the outside of the pressure strip 8, a pressure rod 13 is fixedly mounted on the end of the L-shaped plate 12 away from the pressure strip 8, a sliding cavity for limiting the sliding of the L-shaped plate 12 is opened on the inner side of the protective shell 5, a positioning plate 14 is provided on the inner side of the sliding cavity and is located below the L-shaped plate 12, one end of the positioning plate 14 extends to the outside of the protective shell 5, and positioning rods 15 are fixedly mounted on both sides of the positioning plate 14, and the positioning rods 15 are rotatably mounted on the inner side of the sliding cavity of the protective shell 5, and a sleeve plate 16 is fixedly mounted on the end of the positioning plate 14 close to the L-shaped plate 12. The outer side of the sleeve 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 16. A clamping strip 17 is fixedly installed on the end of the positioning plate 14 away from the sleeve 16. 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 rods 28 is provided in the sliding cavity of the protective shell 5;

[0034] When the air in the annular airbag 6 is reduced, the slider 10 is pulled to move by the rebound force of the tension spring 11, so that the slider 10 pulls the pressure strip 8 to squeeze the annular airbag 6 through the slide rod 9, so that the annular airbag 6 maintains the sealing of the protective cover 3. At the same time, the pressure strip 8 drives the L-shaped plate 12 to move along the sliding cavity of the protective cover 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 cover 5 from falling off from the plug 2, and 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 air in time, thereby achieving the effect of safety and easy maintenance.

[0035] Working principle: First, the staff holds the anti-slip pad 26 on the outside of the protective shell 5, puts the inner side of the protective shell 5 on the outside 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 inside of the protective shell 5 contacts the outside 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 rests 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 rebound force 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 of the annular airbag 6 and the pressure strip 8 is squeezed and deformed, thereby preventing a gap from appearing 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 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 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 swings 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, and realizing the locking of the socket 1 and the plug 2. Moreover, 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 docking of the socket 1 and the plug 2.

A pulling hole is provided at one end of the plate 23 away from the sleeve 21, which is convenient for pulling the inserting plate 23 to move along the inner side of the sliding box 22. Support blocks 24 are fixedly installed on both sides of the inserting plate 23, and a guide groove for the support block 24 to limit the sliding of the support block 24 is provided on the inner side of the sliding box 22. A spring 25 is fixedly installed between the outer side of the support block 24 and the inner side of the guide groove of the sliding box 22, so that the inserting plate 23 can move and reset. A guide rod 33 that slides through the support block 24 is fixedly installed in the guide groove of the sliding box 22. The guide rod 33 is located on the inner side of the spring 2 30 to provide guidance for the movement of the support block 24. A storage component is also provided on the inner side of the mounting plate 19.

[0037] In this embodiment: Taking into account that the inner side of the protective shell 5 will enter a certain amount of impurities due to the influence of moisture, when cleaning the inner side of the protective shell 5, the staff can first pull the two plug plates 23 to move along the inner side of the slide box 22, and the plug plates 23 drive the support block 24 to compress the spring 1 25, so that the plug plates 23 are pulled out from the groove on the sleeve 21, and then the slide box 22 is pulled to make the mounting plate 19 drive the protective shell 5 to be pulled out from the outside of the protective sleeve 3, so that the inner side of the protective shell 5 can be cleaned, and the inside of the protective shell 5 can be cleaned without pulling the plug 2 out of the socket 1, and the annular airbag 6 can be replaced easily, thereby improving the convenience of installation, disassembly and maintenance of the protective shell 5.
