[0002] An electronic connector is a component used to achieve electrical connections or signal transmission within or between electronic devices. It connects conductive components in a circuit together through structures such as plugs and sockets, ensuring that current or signals can be transmitted smoothly and stably. Electronic connectors are widely used in various electronic devices, such as computers, mobile phones, home appliances, and automotive electronics. They are an indispensable part of modern electronic systems, and their performance directly affects the stability and reliability of electronic devices. Automotive connectors are important components that electronic engineers frequently deal with. Their core function is crucial: to build a bridge between disconnected circuits or isolated circuits, allowing current to flow smoothly and ensuring that the circuit can operate normally and achieve its intended function. Automotive connectors come in a variety of shapes and structures, with rich variations. Traditional electronic connectors typically use rubber rings for compression sealing between the male and female heads. However, when faced with pressure exceeding a certain level or more dynamic workloads, the rubber rings are prone to deformation or extrusion, which leads to sealing failure and affects the reliability and stability of the connector. Therefore, a waterproof sealing gasket and its electronic connector are proposed to address the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a waterproof sealing gasket and its electronic connector to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A waterproof sealing gasket and its electronic connector include a female end assembly, a male end assembly mounted on the front end of the female end assembly, a passive compression assembly mounted near the upper end of the female end assembly, the female end assembly including a mounting base, a plug-in cylinder fixedly connected to the front end of the mounting base, an annular groove, a vent channel and a column groove formed on the inner side of the plug-in cylinder, a rubber sealing ring fixedly connected to the inner side of the annular groove, the male end assembly including a male head, a limiting ring groove formed near the outer periphery of the male head, a guide groove formed near the rear end of the male head, a convex ring rotatably connected to the inner circumference of the limiting ring groove, a sleeve fixedly connected to the rear end of the convex ring, and an internal thread groove formed on the inner side of the sleeve.

[0005] As a further optimization of this utility model, a spring is fixedly connected to the lower end of the column groove, and an extended circular plate is fixedly connected to the top of the spring, with the extended circular plate sliding inside the column groove.

[0006] As a further optimization of this utility model, the top of the extended circular plate is fixedly connected to a protrusion, the protrusion extends out of the inner side of the column groove, and the upper end of the protrusion is provided with a slope.

[0007] As a further optimization of this utility model, the column groove, the vent, and the annular groove are connected, and the vent is located at the lower end of the column groove.

[0008] As a further optimization of this utility model, the male connector is inserted into the interior of the connector tube, the guide groove and the guide block are slidably engaged to limit the position of the male connector, and the guide block is fixed on the inner side of the connector tube.

[0009] As a further optimization of this utility model, the sleeve is fitted onto the outside of the plug-in cylinder, and the sleeve is screwed onto the threaded outside of the plug-in cylinder through an internal threaded groove.

[0010] As a further optimization of this utility model, the protrusion is retracted into the groove by the extrusion of the sleeve, and a rubber sealing ring is fixedly connected to the outer side of the extended circular plate, which seals the extended circular plate and the insertion cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, by setting up a female end component, a male end component, and a passive compression component, the device changes the traditional electronic connector's reliance on rubber ring compression for sealing.

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.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-7 This utility model provides a technical solution: A waterproof sealing gasket and its electronic connector include a female end assembly 1, a male end assembly 2 mounted on the front end of the female end assembly 1, a passive compression assembly 3 mounted near the upper end of the female end assembly 1, the female end assembly 1 includes a mounting base 11, a plug-in cylinder 12 fixedly connected to the front end of the mounting base 11, an annular groove 13, a vent 15 and a column groove 16 are formed on the inner side of the plug-in cylinder 12, a rubber sealing ring 14 is fixedly connected to the inner side of the annular groove 13, the male end assembly 2 includes a male head 21, a limiting ring groove 22 is formed near the outer periphery of the male head 21, a guide groove 23 is formed near the rear end of the male head 21, a protruding ring 24 is rotatably connected to the inner circumference of the limiting ring groove 22, a sleeve 25 is fixedly connected to the rear end of the protruding ring 24, and an internal thread groove 26 is formed on the inner side of the sleeve 25.

[0017] As a further implementation of this solution, a spring 17 is fixedly connected to the lower end of the groove 16, and an extension circular plate 31 is fixedly connected to the top of the spring 17. The extension circular plate 31 slides inside the groove 16. With the above arrangement, the elastic force of the spring 17 can keep the passive extrusion component 3 moving upward, so that some of the gas inside the rubber sealing ring 14 can be drawn into the groove 16, making the rubber sealing ring 14 initially concave. As a further implementation of this solution, a protrusion 33 is fixedly connected to the top of the extended circular plate 31. The protrusion 33 extends out of the inner side of the column groove 16. A slope 34 is provided at the upper end of the protrusion 33. Through the above-mentioned arrangement, the extension design of the protrusion 33 and the inclined structure of the slope 34 enable the sleeve 25 to smoothly contact and squeeze the protrusion 33 when it moves backward, thereby realizing the downward movement of the extended circular plate 31, thereby realizing the transfer of gas inside the column groove 16, so that the rubber sealing ring 14 collides and fits against the outside of the male head 21, achieving a sealing effect. As a further implementation of this solution, the column groove 16, the vent 15 and the annular groove 13 are connected. The vent 15 is located at the lower end of the column groove 16. Through the above arrangement, the annular groove 13 with its circular structure and the column groove 16 and the vent 15 with their connected design allow gas to flow freely inside, providing the necessary air pressure channel for the expansion of the sealing structure and improving the sealing response speed and effect. As a further implementation of this solution, the male connector 21 is inserted into the interior of the connector tube 12. The guide groove 23 and the guide block 18 are slidably engaged to limit the position of the male connector 21. The guide block 18 is fixed inside the connector tube 12. Through the above settings, the insertion design of the male connector 21 and the sliding engagement of the guide groove 23 and the guide block 18 ensure the stable installation and precise positioning of the male connector 21 inside the connector tube 12, improve the stability and reliability of the connection, and reduce the risk of seal failure due to improper installation. As a further implementation of this solution, the sleeve 25 is sleeved on the outside of the plug-in sleeve 12, and the sleeve 25 is screwed to the thread on the outside of the plug-in sleeve 12 through the internal thread groove 26. Through the above-mentioned arrangement, the sleeve 25 sleeve design and the screw installation of the internal thread groove 26 to the thread on the outside of the plug-in sleeve 12 provide a stable mechanical connection and precise adjustment capability, so that the sleeve 25 can smoothly drive the male head 21 to move when it moves backward, so as to achieve the effect of stable insertion of the male head 21 and the plug-in sleeve 12. As a further implementation of this solution, the protrusion 33 is retracted into the groove 16 by the compression of the sleeve 25. A rubber sealing ring 32 is fixedly connected to the outside of the expansion round plate 31. The rubber sealing ring 32 seals the expansion round plate 31 and the plug-in cylinder 12. Through the above-mentioned arrangement, the retraction design of the protrusion 33 and the sealing function of the rubber sealing ring 32 ensure the sealing performance between the expansion round plate 31 and the plug-in cylinder 12 during the sealing process, prevent gas leakage, improve the reliability and stability of the seal, and extend the service life of the connector.

[0018] Workflow: During assembly, align the guide groove 23 with the guide block 18 and insert the male head 21 into the inside of the connector 12. After moving the male head 21 backward by three millimeters, the internal thread groove 26 of the sleeve 25 is just squeezed out by the thread on the outside of the connector 12. At this time, operate the sleeve 25 and rotate the sleeve 25 to connect with the thread on the outside of the connector 12 through the internal thread groove 26. As a result, the sleeve 25 will move backward. During this process, the sleeve 25 will drive the convex ring 24 to rotate. The convex ring 24 rotates inside the limiting ring groove 22. This will also drive the male head 21 to move backward through the convex ring 24, so that the male head 21 is inserted into the inside of the connector 12, completing the installation. During sealing, following the same principle, as the sleeve 25 moves backward, it first contacts the slope 34 formed by the protrusion 33. The slope 34 has an inclined shape. Through the compression of the sleeve 25, the protrusion 33 gradually moves downward, causing the rubber sealing ring 32 to move downward. The expanding circular plate 31 compresses the spring 17, which in turn resets the passively compressed assembly 3 upward. Because the rubber sealing ring 32 seals the expanding circular plate 31 and the insert sleeve 12, the gas inside the column groove 16 will enter the annular recess through the vent 15. Inside the groove 13, the air pressure inside the annular groove 13 increases. Under the action of air pressure, the rubber sealing ring 14 expands. After the rubber sealing ring 14 expands, it will fit against the outer side of the male head 21. The guide groove 23 extends forward and connects to the limiting ring groove 22, thus leaving space for sealing between the rubber sealing ring 14 and the male head 21, thereby achieving the sealing effect between the inner side of the plug-in cylinder 12 and the outer side of the male head 21. The passive extrusion component 3 is set at the rear end of the plug-in cylinder 12, which can prevent the rubber sealing ring 14 from expanding prematurely and causing wear between the rubber sealing ring 14 and the outer side of the male head 21. Based on the above principles, the device changes the traditional method of sealing by squeezing the rubber ring. This sealing method achieves sealing by transferring gas during installation, thereby expanding the sealing structure. This significantly reduces the phenomenon of damage or displacement of the sealing ring caused by squeezing, and ensures the reliability and stability of the seal after the electronic connector is installed.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
