[0002] The M12 waterproof connector is a 12mm diameter circular electrical connector widely used in industrial automation, sensor connections, robotics, rail transportation, outdoor monitoring equipment, and other scenarios for transmitting power, signals, or data.

[0003] When using a traditional M12 waterproof connector, the first step is to align the male connector plug with the female connector socket and insert it. After insertion, manually rotate the outer nut to tighten it clockwise.

[0004] Although this method can complete the connection of the M12 waterproof connector, the nut will wear out or strip due to frequent tightening over a long period of time, thus affecting the waterproof performance of the M12 waterproof connector. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-sealing M12 waterproof connector, which aims to improve the problem in the prior art where the nut is worn or stripped due to frequent tightening, thus affecting the waterproof effect of the M12 waterproof connector.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-sealing M12 waterproof connector, comprising:

[0008] Male plug;

[0009] The female plug is connected to the male plug.

[0010] Two plugs are fixedly connected to the outer left side of the female plug;

[0011] Two mounting cavities are formed on both sides of the interior of the male plug;

[0012] Two guide blocks and two horizontal plates are provided. The two guide blocks are slidably connected inside the two mounting cavities, and the two horizontal plates are fixedly connected to the outside of the two guide blocks.

[0013] Two protrusions and two springs, the two protrusions being fixedly connected to the bottom of the two guide blocks, and the two springs being fixedly connected to the top of the two guide blocks;

[0014] And a protective component for protecting the connector joint.

[0015] Furthermore, the protective assembly includes two guide rods, which are fixedly connected to the outer sides of the female plug. Each of the two guide rods is slidably connected to a movable block. Each of the two movable blocks is fixedly connected to a connecting plate on both sides of its outer side. Each of the two connecting plates is fixedly connected to a protective plate.

[0016] Furthermore, the male plug has through holes on both sides inside, and the two protrusions are slidably connected inside the two through holes.

[0017] Furthermore, the male plug has through holes on both sides of its exterior, and the two horizontal plates are slidably connected inside the two through holes.

[0018] Furthermore, each of the two insert blocks has a slot inside, and the two protrusions are inserted into the two slots.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-5This utility model provides an embodiment of a high-sealing M12 waterproof connector, comprising: a male plug 1; a female plug 2, the male plug 1 and the female plug 2 being inserted into each other; two plug blocks 3, the two plug blocks 3 being fixedly connected to the outer left side of the female plug 2; two mounting cavities 5, the two mounting cavities 5 being formed on both sides inside the male plug 1; two guide blocks 6 and two horizontal plates 7, the two guide blocks 6 being slidably connected inside the two mounting cavities 5, the two horizontal plates 7 being fixedly connected to the outer side of the two guide blocks 6; two protrusions 9 and two springs 8, the two protrusions 9 being fixedly connected to the bottom of the two guide blocks 6, the two springs 8 being fixedly connected to the top of the two guide blocks 6; and a protective assembly. For the connector joint used for protection, the male plug 1 has through holes 11 on both sides inside, and two protrusions 9 are slidably connected inside the two through holes 11. The through holes 11 facilitate the movement of the protrusions 9. The male plug 1 has through holes 2 on both sides outside, and two horizontal plates 7 are slidably connected inside the two through holes 2 12. The through holes 2 12 facilitate the movement of the horizontal plates 7. The two insert blocks 3 have slots 10 inside, and the two protrusions 9 are inserted into the two slots 10, which improves the stability of the connection between the male plug 1 and the female plug 2. The male plug 1 has a socket 4 on the right side inside, and the two insert blocks 3 are inserted into the two sockets 4, which serves as the initial connection between the male plug 1 and the female plug 2.

[0035] Specifically, when assembling the male plug 1 and female plug 2, firstly, the two horizontal plates 7 are moved simultaneously to both sides. At this time, the two horizontal plates 7 slide horizontally under manual operation, causing the two guide blocks 6 fixedly connected to their bottoms to slide within the two mounting cavities 5 inside the connector housing. During the movement of the guide blocks 6, the two protrusions 9 fixed to their tops also move synchronously. Simultaneously, the movement of the two protrusions 9 applies pressure to the two springs 8 located behind them. Therefore, the two springs 8 will undergo compression deformation under pressure. When the guide blocks 6 push the protrusions 9 away from their original positions, the outer left side of the female plug 2... Two pre-fixed plug blocks 3 are aligned with two sockets 4 opened on the right side inside the male plug 1. The plug blocks 3 are inserted into the sockets 4 to achieve the initial connection between the plugs. Then, after releasing the two horizontal plates 7, the two protrusions 9 automatically spring back to their original positions under the reaction force of the two springs 8 and are inserted into the two pre-set slots 10 inside the two plug blocks 3 to complete the automatic locking and fixing. Through the design of this structure, the M12 waterproof connector can achieve a fast and stable connection during the docking process without the need for rotation and tightening like traditional connectors. This avoids the thread wear or stripping problems caused by frequent tightening and further enhances the overall waterproof performance of the connector.

[0036] Reference Figures 3-6The protective assembly includes two guide rods 14, which are fixedly connected to the outer sides of the female plug 2. Each guide rod 14 is slidably connected to a movable block 15. Each movable block 15 is fixedly connected to a connecting plate 16 on both sides of its outer side. Each connecting plate 16 is fixedly connected to a protective plate 17. Each side of the female plug 2 has a mounting groove 13. The two movable blocks 15 are slidably connected inside the two mounting grooves 13. The mounting grooves 13 facilitate the movement of the movable blocks 15. The two protective plates 17 are made of rubber, which has good elasticity and flexibility and can fit tightly to the surface of the connector.

[0037] Specifically, after the male plug 1 and female plug 2 are connected, the two protective plates 17 are moved. The movement of the protective plates 17 causes the two connecting plates 16 fixed at their bottom to move. The connecting plates 16 cause the two moving blocks 15 fixed at their bottom to slide laterally outside the two guide rods 14. Finally, the protective plates 17 cover the connection point of the male plug 1 and female plug 2. In this way, the two rubber protective plates 17 can protect the connection point of the M12 waterproof connector. The protective plates 17 can effectively prevent moisture, dust, oil and other external substances from entering the connector. At the same time, they enhance the sealing of the connection point, thereby extending its service life.

[0038] Working principle: When the male plug 1 and female plug 2 are connected, firstly, the horizontal plates 7 move to both sides simultaneously. The movement of the two horizontal plates 7 moves the two guide blocks 6 fixed at the bottom inside the two mounting cavities 5. When the two guide blocks 6 move, they move the two protrusions 9 fixed at the top synchronously. At the same time, the two springs 8 are squeezed, causing the two springs 8 to deform under force. Then, the two plugs 3 fixed on the left side of the female plug 2 are aligned with the two sockets 4 opened on the right side of the male plug 1. Then, the two plugs 3 are inserted into the two sockets 4. At this time, the male plug 1 and female plug 2 complete the connection operation. Then, the two horizontal plates 7 are released. Under the reaction force of the two springs 8, the two protrusions 9 are reset and inserted into the two slots 10 opened inside the two plugs 3. This realizes the connection of the M12 waterproof connector. After connection, there is no need to twist, avoiding the problem of wear or stripping caused by frequent twisting, thereby improving the waterproof effect of the M12 waterproof connector.

[0039] After the male plug 1 and female plug 2 are connected, the two protective plates 17 are moved. The movement of the two protective plates 17 moves the two connecting plates 16 fixed at the bottom. The movement of the two connecting plates 16 moves the two moving blocks 15 fixed at the bottom laterally outside the two guide rods 14, so that the two protective plates 17 cover the connection point of the male plug 1 and female plug 2. Thus, the connection point of the M12 waterproof connector is easily protected by the two rubber protective plates 17. The protective plates 17 further enhance the sealing of the connection point, preventing moisture, dust, oil and other contaminants from entering the connector, thereby improving the service life of the M12 waterproof connector.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
