Description

Technical Field

[0001] The utility model relates to the technical field of marine electric connectors, in particular to a marine electric connector with a self-locking function. Background Art

[0002] In addition to meeting general performance requirements, electrical connectors must also have good contact, reliable operation, and easy maintenance. They are widely used in the marine industry, such as marine electrical connectors.

[0003] There is a seal for a marine electrical connector (authorization announcement number: CN217848452U). It is equipped with a sealing plate that can be raised and lowered at the socket end. When the sealing plate seals the socket end, it prevents the parts inside the socket end from being in contact with moist air for a long time, which may cause a short circuit. When the plug-in is plugged into the socket end, the sealing plate can be adjusted to move up without affecting the connection between the plug-in and the socket end.

[0004] However, this type of marine electrical connector has some shortcomings in actual use: the connection between the plug and the socket end is not tight enough. As the ship sails on the water, the hull and the devices inside the ship will shake, causing the electrical connector on the ship to gradually detach under long-term shaking, thereby causing abnormal operation of the marine electrical connector. Therefore, we propose a marine electrical connector with a self-locking function to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a marine electrical connector with a self-locking function to solve the above problems.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A marine electrical connector with a self-locking function comprises a plug and a socket end, the plug being provided with a connector, the socket end being provided with a slot, the connector of the plug being plugged into the slot on the socket end, the top and bottom sides of the plug being fixedly mounted with a first semicircular side panel, the first semicircular side panel being provided with two fan-shaped slots, the top and bottom sides of the socket end being fixedly mounted with a second semicircular side panel, the second semicircular side panel being provided with a translation slot, the translation slot being provided with an elastic connection mechanism, the second semicircular side panel being provided with two circular chambers respectively, and both circular chambers being provided with an anti-backward deflection mechanism.

[0008] Preferably, the two fan-shaped grooves on the first semicircular side plate are symmetrically arranged, and the two fan-shaped grooves are spliced to form an M shape, so that the positioning protrusion can be deflected and abut against the end of the fan-shaped groove.

[0009] Preferably, the elastic connection mechanism includes an I-shaped translation block movably installed in the translation groove, one end of the first spring is fixedly installed on one side of the I-shaped translation block, the other end of the first spring is fixedly installed on one side of the inner wall of the translation groove, and the top side of the I-shaped translation block is provided with a locking mechanism for two fan-shaped grooves; it is convenient to adjust the two sets of rotating plates and positioning protrusions.

[0010] Preferably, the locking mechanism includes one end of two rotating plates rotatably mounted on the top side of the I-shaped translation block, and positioning protrusions are fixedly mounted on the bottom sides of the other ends of the two rotating plates, and the two positioning protrusions are respectively inserted into the ends of the corresponding fan-shaped grooves; the sloped triangular plate passes through the outside of the second semicircular side plate and fits against one side of the corresponding rotating plate, so as to limit and fix the angular position of the rotating plate after deflection, thereby reducing the situation where the rotating plate deflects back.

[0011] Preferably, the anti-return mechanism includes a circular plate movably installed in the circular chamber, a sloped triangular plate fixedly installed on one side of the circular plate, the sloped triangular plate extends to the outside of the second semicircular side plate and rests on one side of the corresponding rotating plate, one end of a second spring is fixedly installed on the other side of the circular plate, and the other end of the second spring is fixedly installed on one inner wall of the circular chamber.

[0012] Preferably, the slope triangular plate is provided with an arc-shaped slope, and the arc-shaped slope on the slope triangular plate is located on a side away from the rotating plate, so as to facilitate the rotating plate to pass through the slope triangular plate after deflection.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The marine electrical connector with a self-locking function uses two sets of elastic connection mechanisms to insert the positioning protrusions on the rotating plate into the corresponding fan-shaped grooves, and then deflect the two sets of rotating plates. When the rotating plates are deflected and abut against the arc slopes on the corresponding slope triangular plates, the slope triangular plates and circular plates are squeezed downward, causing the second spring to be deformed and compressed under force until the positioning protrusions on the rotating plate are deflected and abut against the end of the fan-shaped groove. The slope triangular plate is passed through the outside of the second semicircular side plate and fits against one side of the corresponding rotating plate through the anti-return deflection mechanism, thereby limiting and fixing the angular position of the rotating plate after deflection, reducing the situation where the rotating plate deflects back. The marine electrical connector in this case can achieve a stable locking connection between the plug-in and the socket end, avoiding the situation where the marine electrical connector is separated due to shaking, and ensuring the normal operation of the marine electrical connector.

The connector 3 of the plug-in 1 is plugged into the slot 4 on the socket end 2. The top and bottom sides of the plug-in 1 are fixedly mounted with a first semicircular side plate 5, and the first semicircular side plate 5 has two fan-shaped grooves 6. The top and bottom sides of the socket end 2 are fixedly mounted with a second semicircular side plate 7, and the second semicircular side plate 7 has a translation groove 8, and an elastic connection mechanism is provided in the translation groove 8. Two circular chambers 13 are respectively provided in the second semicircular side plate 7, and both circular chambers 13 are provided with an anti-backward deflection mechanism.

[0022] Furthermore, the two fan-shaped grooves 6 on the first semicircular side plate 5 are symmetrically arranged, and the two fan-shaped grooves 6 are spliced to form an M shape; this facilitates the positioning protrusion 12 to abut against the end of the fan-shaped groove 6 after deflection.

[0023] Furthermore, the elastic connection mechanism includes an I-type translation block 9 movably installed in the translation groove 8, one end of the first spring 10 is fixedly installed on one side of the I-type translation block 9, and the other end of the first spring 10 is fixedly installed on the inner wall of one side of the translation groove 8. The top side of the I-type translation block 9 is provided with a locking mechanism for the two fan-shaped grooves 6; it is convenient to adjust the two sets of rotating plates 11 and the positioning protrusions 12.

[0024] Furthermore, the locking mechanism includes one end of two rotating plates 11 rotatably mounted on the top side of the I-shaped translation block 9, and the bottom sides of the other ends of the two rotating plates 11 are fixedly mounted with positioning protrusions 12, and the two positioning protrusions 12 are respectively inserted into the ends of the corresponding fan-shaped grooves 6; through the sloped triangular plate 15, it penetrates to the outside of the second semicircular side plate 7 and fits against one side of the corresponding rotating plate 11, so as to limit and fix the angular position of the rotating plate 11 after deflection, thereby reducing the situation where the rotating plate 11 deflects back.

[0025] Furthermore, the anti-return mechanism includes a circular plate 14 movably installed in the circular chamber 13, a sloped triangular plate 15 is fixedly installed on one side of the circular plate 14, the sloped triangular plate 15 passes through the outside of the second semicircular side plate 7 and rests on one side of the corresponding rotating plate 11, and one end of a second spring 16 is fixedly installed on the other side of the circular plate 14, and the other end of the second spring 16 is fixedly installed on one inner wall of the circular chamber 13.
