Its power supply devices include various forms such as diesel generator sets, gas generator sets, hydrogen fuel cell systems and solar power generation systems. When the generator vehicle is performing power operation, cables are required for power transmission. In order to facilitate the connection of the power supply by the staff, quick connectors are generally installed on the cables.

[0003] When connecting existing quick connectors, the male plug is usually inserted into the female plug, and then the male plug is rotated. The rubber stop on the surface of the insertion end is used to limit and fix it, so that the male plug and the female plug are locked together. However, after repeatedly inserting and removing the male plug and the female plug, the rubber stop is prone to wear, which can cause the male plug and the female plug to loosen, or even cause the male plug to fall out of the female plug, affecting its use.

[0004] In addition, the dust covers on the male and female plugs need to be removed before use. When the male and female plugs are connected, these dust covers are usually tied near the plug with a connecting rope. They tend to sway around the plug, which not only affects the operator's operation of the cable, but also makes it easy for dust to enter the dust cover and then enter the plug during subsequent installation.

Detailed Implementation

[0024] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 7 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0025] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0026] This utility model is a low-voltage quick connector for power operations. Existing cable quick connectors rely solely on rubber stops for rotational locking during use, but repeated plugging and unplugging operations can easily lead to loosening of the connection or even detachment of the connector.

[0027] The dust cover removed when the plug is connected can cause it to shake around during use, affecting the operator's work. It can also easily allow dust to enter the dust cover, which can then enter the plug when the dust cover is reinstalled, affecting its use.

[0028] As one embodiment, this utility model includes a female plug 1, a male plug 2, a first dust cover 4, and a second dust cover 6. One end of the female plug 1 is provided with a first connecting end 3, and one end of the male plug 2 is provided with a second connecting end 5. Both the first connecting end 3 and the second connecting end 5 are cylindrical, and the outer diameter of the second connecting end 5 matches the inner diameter of the first connecting end 3 to form a tight fit. The first connecting end 3 and the second connecting end 5 cooperate with each other. A first support block 9 is fixedly connected to the top of the female plug 1. An insertion groove 10 is opened on one side of the first support block 9. The insertion groove 10 is rectangular, and a lifting stop block 16 is provided on the top of the insertion groove 10. The stop block 16 is cylindrical. A second support block 11 is fixedly connected to the top of the male plug 2. An insertion block 12 is fixedly connected to one side of the second support block 11. The insertion block 12 cooperates with the insertion groove 10. A fixing hole 13 is opened on the insertion block 12. The fixing hole 13 is circular, and the stop block 16 cooperates with the fixing hole 13.

[0029] In this embodiment, the male plug 2 and the female plug 1 are respectively installed at both ends of the cable to be connected. During connection, the male plug 2 (its second connecting end 5) is inserted into the female plug 1 (its first connecting end 3). As the male plug 2 moves toward the female plug 1, the insertion block 12 on the second support block 11 is inserted into the insertion groove 10 on the first support block 9. The two work together to provide auxiliary guidance. The insertion block 12 slides in the insertion groove 10 until it is in place. At the same time, the second support block 11 on the male plug 2 contacts the first support block 9 on the female plug 1. At this time, the male plug 2 and the female plug 1 are connected (the electrical connection is also established). After the connection is completed, the stop block 16 at the top of the insertion groove 10 slides down and is locked into the fixing hole 13 on the insertion block 12, thereby limiting the insertion block 12 and making the connection between the female plug 1 and the male plug 2 more stable.

[0030] As an example, a fixed cylinder 14 is fixedly connected to the top of the first support block 9. A baffle 15 is slidably connected inside the fixed cylinder 14. A stop block 16 is cylindrical and cooperates with the inner wall of the fixed cylinder 14. The stop block 16 is fixedly connected to the bottom of the baffle 15. A support rod 17 is fixedly connected to the top of the baffle 15. The top end of the support rod 17 passes through the fixed cylinder 14 and is fixedly connected to a pull ring 19. The pull ring 19 is located above the fixed cylinder 14. A spring 18 is provided on the top of the baffle 15. The spring 18 is sleeved on the support rod 17 and is located inside the fixed cylinder 14.

[0031] In this embodiment, when the insertion block 12 needs to slide to a predetermined position in the insertion slot 10, the operator pulls the pull ring 19 upwards. The pull ring 19 causes the stop block 16 to slide upwards and rise within the fixed cylinder 14. After the stop block 16 rises, it frees up space in the insertion slot 10, allowing the insertion block 12 to slide smoothly into place within the insertion slot 10. When the stop block 16 slides upwards, it compresses the spring 18 located between the stop block 16 and the fixed cylinder 14, causing the spring 18 to store elastic potential energy. When the insertion block 12 slides into place, the operator releases the pull ring 19. At this time, the stop block 16 is pushed downwards and resets within the fixed cylinder 14 by the elastic force of the compressed spring 18 below. As the stop block 16 moves downwards, it also drives the top support rod 17 and the pull ring 19 connected to it to reset downwards together. Finally, the bottom of the stop block 16 is inserted into the fixing hole 13 on the insertion block 12, thereby fixing the insertion block 12.

[0032] As an example, the first dust cover 4 is sleeved on the first connecting end 3, and the second dust cover 6 is sleeved on the second connecting end 5. A fixing groove 7 is provided on one side of the first dust cover 4. The fixing groove 7 is in the shape of a cross. A fixing block 8 is fixedly connected to one side of the second dust cover 6. The fixing block 8 is also in the shape of a cross. The fixing block 8 cooperates with the fixing groove 7.

[0033] The fixing groove 7 has a cavity, which allows the fixing block 8 to rotate after being inserted into the fixing groove 7.

[0034] In this embodiment, the first dust cover 4 and the second dust cover 6 are used to cover the connection positions of the female plug 1 and the male plug 2, blocking dust when the plugs are not connected and preventing dust from entering the plugs and affecting subsequent connections. In use, the second dust cover 6 is aligned with the first dust cover 4, and the fixing block 8 on one side of the second dust cover 6 is inserted into the fixing groove 7 on one side of the first dust cover 4. After insertion, the second dust cover 6 is rotated to connect the first dust cover 4 and the second dust cover 6 together. Then, the first dust cover 4 and the second dust cover 6 are removed as a whole for easy storage.

[0035] As an example, a storage tube 20 is fixedly connected to the first support block 9, and a rotating shaft 21 is rotatably connected inside the storage tube 20. Two limiting plates 22 are fixedly connected to the rotating shaft 21. Torsion springs 23 are provided between the two limiting plates 22 and the side wall of the storage tube 20. A pull rope 24 is provided on the rotating shaft 21. The pull rope 24 is located between the two limiting plates 22. The other end of the pull rope 24 passes through the storage tube 20 and is fixedly connected to one side of the first dust cover 4.

[0036] In this embodiment, the worker pulls the pull rope 24 to pull it out of the storage tube 20 and drive the rotating shaft 21 to rotate, thereby pulling the first dust cover 4 away from the storage tube 20 and covering the first connecting end 3 of the female plug 1. During this process, the limiting plate 22 of the rotating shaft 21 forces the torsion springs 23 on both sides to twist and store energy. When it is needed, the first dust cover 4 covering the first connecting end 3 is removed (the second dust cover 6 can be pre-installed on it). The removal action triggers the torsion springs 23 to release energy, driving the rotating shaft 21 to rotate in the opposite direction to wind and retract the pull rope 24 into the storage tube 20. At the same time, the first dust cover 4 (and the second dust cover 6) are pulled closer to the storage tube 20 and finally stop on one side of the storage tube 20 for limiting.

[0037] As an example, a label 25 is fixedly connected to one side of both the female plug 1 and the male plug 2.

[0038] In this embodiment, the male plug 2 and the female plug 1 are marked with a sign 25 to facilitate identification by staff.

[0039] Working principle of this utility model:

[0040] In use, the second dust cover 6 is removed from the second connecting end 5 and installed on the first dust cover 4. Then, the first dust cover 4 covering the first connecting end 3 is removed. After the first dust cover 4 is loosened, the torsion spring 23 drives the limiting plate 22 and the rotating shaft 21 connected thereto to rotate in the opposite direction inside the storage tube 20. The pull rope 24 is wound around the rotating shaft 21 and retracted into the storage tube 20. At the same time, the first dust cover 4 and the second dust cover 6 installed thereon are pulled to move to one side of the storage tube 20 and are limited and fixed.

[0041] After removing the first dust cover 4 and the second dust cover 6, insert the second connecting end 5 into the first connecting end 3. At this time, the insertion block 12 on the second support block 11 is inserted into the insertion slot 10 on the first support block 9, providing guidance and initial positioning for the connection of the female plug 1 and the male plug 2.

[0042] As the insertion block 12 goes deeper into the insertion slot 10 and gradually approaches the stop block 16, the pull ring 19 is pulled upward to move the stop block 16 into the fixed cylinder 14, thereby freeing up space in the insertion slot 10 so that the insertion block 12 can continue to move to the predetermined position. When the pull ring 19 is released, the baffle 15 descends in the fixed cylinder 14 under the action of the spring 18, pushing the stop block 16 at its bottom to move down into the fixing hole 13 on the insertion block 12, thus achieving the final limit of the insertion block 12.

[0043] The present invention has the following technical effects.

[0044] 1. This utility model provides auxiliary alignment and guidance when the male plug 2 and female plug 1 are plugged in through the first support block 9, the insertion groove 10, the second support block 11 and the insertion block 12. Through the cooperation of the fixing hole 13, the stop block 16, the baffle 15 and the spring 18, the connection of the male plug 2 and female plug 1 is locked after they are connected, ensuring the connection stability of the two during long-term use.

[0045] 2. This utility model uses a storage tube 20, a torsion spring 23, a fixing groove 7, and a fixing block 8 to fix the removed first dust cover 4 and second dust cover 6 to each other, and stores them on one side of the female plug 1 through the storage tube 20, preventing the removed first dust cover 4 and second dust cover 6 from falling, swinging, or interfering with the operation. The identification plate 25 makes it convenient for workers to quickly and accurately identify the female plug 1 and the male plug 2.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
