Description

Technical Field

[0001] This utility model belongs to the field of electrical connection technology, specifically a waterproof and dustproof quick-plug connector. Background Technology

[0002] Quick-connect connectors (also known as fast-plug or quick-connect connectors) are a type of connection element that achieves connection and disconnection in seconds without additional tools through snap-fit, push-pull, or self-locking structures. They are widely used in electrical, pneumatic, hydraulic, and radio frequency applications.

[0003] The core working principle of the quick-connect connector is to achieve quick engagement and unlocking of the male and female ends through a mechanical self-locking structure. The whole can be disassembled into three core working links: locking and unlocking, media transmission, and sealing protection.

[0004] However, traditional quick-plug connectors have relatively weak protection at the connection points. In dusty, humid, or splashing water environments such as outdoors and factory workshops, dust, water droplets, and other impurities can easily enter the connector through the connection gaps, causing minor issues such as unstable signal transmission and poor equipment contact, or even short circuits. Therefore, a waterproof and dustproof quick-plug connector is proposed to address the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a waterproof and dustproof quick-plug connector.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The waterproof and dustproof quick-plug connector of this utility model includes a first connector, and a second connector is inserted into the end of the first connector; a first support block is fixedly connected to the end of the first connector, and multiple fixed rails are fixedly connected to the outer wall of the first support block; a second support block is fixedly connected to the end of the second connector; a protective plate is slidably connected to the outer wall of the first support block through multiple fixed rails; and a limit plate is fixedly connected to the end of the protective plate.

[0007] Preferably, a plurality of connectors are fixedly connected to the middle of the protective plate, a spring is fixedly connected to the inner wall of the connector, a slider is fixedly connected to the end of the spring, the slider is slidably disposed on the inner wall of the connector, a positioning post is fixedly connected to the bottom of the slider, and a rubber ring is fixedly connected to the bottom of the plurality of positioning posts.

[0008] Preferably, a magnetic plate is fixed to the end of the protective plate. The magnetic plate is located near the side of the second support block. A fixing frame is fixed to the side wall of the second support block. A metal sheet is fixed to the inner wall of the fixing frame. The metal sheet and the magnetic plate are attracted to each other.

[0009] Preferably, a protective pad is fixed to the outer wall of the second support block.

[0010] Preferably, a friction plate is fixedly connected to the outer wall of the protective plate.

[0011] The beneficial effects of this utility model are: This invention provides a waterproof and dustproof quick-plug connector. The unfolded protective plate can form a full-range shield at the connection between the first connector and the second connector, effectively preventing dust, water droplets and other impurities from entering the connection gap. This solves the problem that the connection of traditional connectors is easily corroded by dust and rainwater after plugging, resulting in poor contact or short circuit, and improves the service life and stability of the connector in complex environments.

[0012] This invention provides a waterproof and dustproof quick-plug connector. The soft material of the rubber ring can buffer the friction when the conductive wire twists, avoiding wear and breakage of the conductive wire at the end of the first connector due to long-term contact with the hard structure, thus improving the protection and durability of the conductive wire.

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below.

[0018] like Figure 1-4 As shown, a waterproof and dustproof quick-connect connector includes a first connector 1, with a second connector 11 inserted into the end of the first connector 1; a first support block 12 is fixedly connected to the end of the first connector 1, and multiple fixed rails 13 are fixedly connected to the outer wall of the first support block 12; a second support block 14 is fixedly connected to the end of the second connector 11; a protective plate 15 is slidably connected to the outer wall of the first support block 12 via the multiple fixed rails 13, and a limit piece 16 is fixedly connected to the end of the protective plate 15; after the first connector 1 and the second connector 11 are inserted, the operator holds the outer wall of the protective plate 15 and slides it along the multiple fixed rails 13. The guide rail 13 pushes the protective plate 15 towards the second support block 14 until the inner wall of the protective plate 15 is in complete contact with the second support block 14. At this time, the protective plate 15 unfolds and covers the connection between the first connector 1 and the second connector 11. The limiting piece 16 can limit the excessive sliding of the protective plate 15. This step, through the unfolded protective plate 15, can form an all-round shield for the connection between the first connector 1 and the second connector 11, effectively preventing dust, water droplets and other impurities from entering the connection gap. This solves the problem that the connection is easily corroded by dust and rainwater after the traditional connector is plugged in, resulting in poor contact or short circuit, and improves the service life and stability of the connector in complex environments.

[0019] like Figure 1-4 As shown, several connectors 2 are fixedly connected to the middle of the protective plate 15. A spring 21 is fixedly connected to the inner wall of the connector 2. A slider 22 is fixedly connected to the end of the spring 21. The slider 22 is slidably disposed on the inner wall of the connector 2. A positioning post 23 is fixedly connected to the bottom of the slider 22. Rubber rings 24 are fixedly connected to the bottom of the multiple positioning posts 23. The spring 21 is provided inside the connector 2 fixed to the middle of the protective plate 15. The slider 22 connected to the end of the spring 21 can slide on the inner wall of the connector 2. The positioning post 23 at the bottom of the slider 22 drives the rubber ring 24 to unfold, so that the rubber ring 24 fits against the outer wall of the conductive wire at the end of the first connector 1. When the conductive wire twists, it will directly contact the soft rubber ring 24. This step can buffer the friction force when the conductive wire twists through the soft material of the rubber ring 24, avoiding the problem of wear and breakage of the conductive wire at the end of the first connector 1 due to long-term contact with the hard structure, thus improving the protection and durability of the conductive wire.

[0020] like Figure 1-4 As shown, a magnetic plate 3 is fixed to the end of the protective plate 15. The magnetic plate 3 is located near the second support block 14. A fixing frame 31 is fixed to the side wall of the second support block 14. A metal sheet 32 ​​is fixed to the inner wall of the fixing frame 31. The metal sheet 32 ​​and the magnetic plate 3 are attracted to each other. During the process of sliding the protective plate 15 along the fixing rail 13 onto the second support block 14, the magnetic plate 3 at the end of the protective plate 15 will gradually approach the fixing frame 31 on the side wall of the second support block 14, and finally adhere to the metal sheet 32 ​​on the inner wall of the fixing frame 31. This step can initially fix the protective plate 15 through the magnetic attraction between the magnetic plate 3 and the metal sheet 32, preventing the protective plate 15 from shifting or falling off due to vibration or external force during use. This solves the problem that the protective plate 15 is easy to loosen by sliding contact alone, and improves the stability and reliability of the protective structure.

[0021] like Figure 1-4 As shown, a protective pad 4 is fixed to the outer wall of the second support block 14. When the protective plate 15 slides to contact the second support block 14, the protective pad 4 on the outer wall of the second support block 14 will fill the connection surface between the protective plate 15 and the second support block 14, increasing the friction and sealing when they are in contact. This step can effectively improve the fit between the protective plate 15 and the second support block 14 through the protective pad 4, reduce the generation of gaps, and further block dust and moisture from entering.

[0022] like Figure 1-4 As shown, a friction plate 5 is fixed to the outer wall of the protective plate 15. When the operator pushes the protective plate 15, his hand will come into contact with the friction plate 5 on the outer wall of the protective plate 15. The rough surface of the friction plate 5 can increase the friction between the hand and the protective plate 15. This step improves the stability of holding the protective plate 15 through the friction plate 5, avoids slipping or slipping during the pushing process, and solves the problem of inconvenient operation caused by the smooth outer wall of the protective plate 15.

[0023] Working principle: After the first connector 1 and the second connector 11 are connected, the operator holds the outer wall of the protective plate 15 and pushes it along the multiple fixed rails 13 on the outer wall of the first support block 12 towards the second support block 14 until the inner wall of the protective plate 15 is in complete contact with the second support block 14. At this time, the protective plate 15 unfolds and covers the connection between the first connector 1 and the second connector 11. The limiting piece 16 can limit the excessive sliding of the protective plate 15. The connector 2 fixed in the middle of the protective plate 15 is equipped with a spring 21. The slider 22 connected to the end of the spring 21 can slide on the inner wall of the connector 2. The positioning post 23 at the bottom of the slider 22 drives the rubber ring 24 to unfold, so that the rubber ring 24 fits against the outer wall of the conductive wire at the end of the first connector 1. When the conductive wire twists, it will directly contact the soft rubber ring 24. During the process of sliding the protective plate 15 along the fixed rail 13 onto the second support block 14, the magnetic plate 3 at the end of the protective plate 15 will gradually approach the fixed frame 31 on the side wall of the second support block 14, and finally adhere to the metal sheet 32 ​​on the inner wall of the fixed frame 31. When the protective plate 15 slides to contact the second support block 14, the protective pad 4 on the outer wall of the second support block 14 will fill the connection between the protective plate 15 and the second support block 14, increasing the friction and sealing when they contact each other. When the staff pushes the protective plate 15, their hands will contact the friction plate 5 on the outer wall of the protective plate 15. The rough surface of the friction plate 5 can increase the friction between the hand and the protective plate 15.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
