Description

Technical Field

[0001] This utility model relates to the field of dustproof component technology, specifically a dustproof rubber plug assembly and an electronic connector. Background Technology

[0002] Electronic connectors, as an indispensable key component of electronic devices, play a bridging role, enabling wires, printed circuit boards, and other components to connect with each other and achieve efficient transmission of current or signals. There are many types of connectors, such as board-to-board connectors and wire-to-board connectors. Different types of connectors vary in shape, size, and performance to meet diverse connection needs and provide important guarantees for the stable operation of electronic products.

[0003] Dustproof components for electronic connectors are key accessories for ensuring connection reliability. Their core function is to prevent dust, moisture, oil and other contaminants from entering the connector interface, avoiding contact oxidation, short circuits or signal transmission obstruction. These components can extend the service life of the connector and enhance its dustproof capability in harsh environments.

[0004] However, current dustproof components face the prominent problem of excessively high friction coefficient between themselves and components in practical applications. This excessive friction is particularly evident during connector insertion and removal operations. When operators perform insertion and removal actions, the edges of the dustproof component and the components will generate severe relative friction, resulting in serious wear on the contact surfaces. With the increase of insertion and removal times, the wear of the dustproof component will gradually intensify, and its edges may develop burrs, missing corners, or even cracks, creating gaps in the tightly fitted areas. Dust, moisture, and other contaminants can then enter the connector through these gaps, causing a significant reduction or even complete loss of dustproof function. Therefore, a dustproof rubber plug assembly and electronic connector are proposed to address the above problems. Utility Model Content

[0030] 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.

[0031] 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.

[0032] Please see Figures 1-7 This utility model provides a technical solution:

[0033] A dustproof rubber plug assembly and an electronic connector include a connecting wire 1, through which a plug seat assembly 2 is fixedly connected. A vent valve 3 is inserted and installed inside the plug seat assembly 2. A dustproof plug assembly 4 is fixedly connected to one side of the plug seat assembly 2. A rotating assembly 5 is spirally connected to the outer side of the plug seat assembly 2. An air storage assembly 6 is fixedly connected to the side of the plug seat assembly 2 away from the dustproof plug assembly 4. The plug seat assembly 2 includes a threaded fixing disc 21, with an inter-disc hole 22 on the inner side of the threaded fixing disc 21. A slot 23 is formed on one side of the threaded fixing disc 21, and a clamping plate 24 is fixedly disposed inside the slot 23. The clamping plate 24 is positioned on the... A rubber plug strip 25 is fixedly connected to one end of the groove 23. A rubber block 26 is bonded and fixed to one side of the clamp 24. The dust plug assembly 4 includes a rubber plug 41. A sealing strip 42 is bonded and fixed to the outside of the rubber plug 41. A first through hole 43 is opened on one side of the rubber plug 41. A support tube 44 is fixedly connected to the inside of the rubber plug 41. The rotating assembly 5 includes a threaded sleeve 51. An anti-slip block 52 is fixedly connected to the outside of the threaded sleeve 51. A retaining ring 53 is bonded and fixed to one end of the threaded sleeve 51. The gas storage assembly 6 includes a rubber sleeve 61. A second through hole 62 is opened on one side of the rubber sleeve 61. A reinforcing rib 63 is fixedly connected to the inside of the rubber sleeve 61.

[0034] As a further implementation of this scheme, several inter-disc holes 22 are provided, and multiple inter-disc holes 22 are evenly distributed in a ring array. The number of slots 23 is the same as the number of clamps 24. The clamps 24 are arc-shaped. The positions of the rubber plugs 25 correspond one-to-one with the positions of the clamps 24. The rubber blocks 26 are provided on the side of the clamps 24 near the gas storage component 6. The inner side of the rubber blocks 26 has a cavity. The slots 23 restrict the movement of the clamps 24 to prevent the clamps 24 from shaking. The clamps 24 and the rubber plugs 25 are inserted into the slots 23 at the same time, which can prevent the clamps 24 from rigidly contacting and breaking with the threaded fixed disc 21. The cavity on the inner side of the rubber blocks 26 gives it a good deformation effect. When subjected to a certain pressure, it will deform, leaving room for the clamps 24 to rotate.

[0035] As a further implementation of this solution, the rubber plug 41 has a ring-shaped transverse projection. Several sealing strips 42 are provided, evenly and equidistantly distributed on the outside of the rubber plug 41. The vertical cross-section of the sealing strips 42 is a semi-elliptical shape. The first through hole 43 is connected to the inter-disc hole 22. A portion of the vent valve 3 is located inside the rubber plug 41. The central axis of the support tube 44 is on the same straight line as the central axis of the rubber plug 41. A threaded fixing disc 21 is fixedly connected to one side of the support tube 44. The rubber plug 41 has a ring-shaped transverse projection and possesses good elasticity, allowing it to tightly fit the outer periphery of the corresponding mating parts, forming a relatively complete... The sealing structure is based on the sealing strip 42, which has a semi-elliptical vertical cross section. This shape has a certain degree of flexibility and adaptability. When the rubber plug 41 comes into contact with mating parts of different shapes or slightly uneven surfaces, the sealing strip 42 can better fit the contact surface and automatically adapt to the slight shape differences, ensuring the reliability of the seal and reducing the risk of seal failure due to the precision of the mating parts. The first through hole 43 is connected to the inter-disc hole 22, ensuring that the gas flow path is unobstructed. The vent valve 3 is integrated into the rubber plug 41, reducing the complexity of external connecting parts, making the overall structure more compact and saving installation space.

[0036] As a further implementation of this solution, the threaded sleeve 51 is fitted on the outside of the threaded fixed plate 21, and several anti-slip blocks 52 are provided, which are arranged in a ring array. The inner side of the retaining ring 53 is arc-shaped and fits against the outer side of the clamping plate 24. Through the threaded connection between the threaded sleeve 51 and the threaded fixed plate 21, a tight and stable connection can be achieved. The anti-slip blocks 52 can prevent slippage when rotating the threaded sleeve 51, ensuring smooth operation and improving the convenience of operation. The arc-shaped inner side of the retaining ring 53 and the groove design that fits against the outer side of the clamping plate 24 can make the retaining ring 53 form a uniform clamping force on the clamping plate 24, avoiding deformation or displacement caused by uneven force on the clamping plate 24.

[0037] As a further implementation of this solution, part of the vent valve 3 is set inside the rubber sleeve 61, and the second through hole 62 is connected to the threaded fixing plate 21. The reinforcing rib 63 has a rectangular horizontal projection. The outer side of the rubber sleeve 61 is in close contact with the rubber block 26. Part of the vent valve 3 is set inside the rubber sleeve 61, which can form a wrap-around protection for the vent valve 3, effectively reducing the impact of external vibration and impact on the vent valve 3, reducing the risk of damage caused by external forces. The reinforcing rib 63 can provide greater support and stability in the horizontal direction, effectively enhancing the structural strength of the rubber sleeve 61.

[0038] An electronic connector comprising a dustproof rubber plug assembly as described in any one of the preceding claims.

[0039] Working process: When using the device, the copper contact at one end of the connecting wire 1 needs to be inserted into the corresponding component. Then, the anti-slip block 52 is rotated to drive the threaded sleeve 51 to rotate. Through the helical engagement between the threaded sleeve 51 and the threaded fixing plate 21, the relative position between the vent valve 3 and the rotating component 5 is changed, thereby causing the retaining ring 53 to slide on the outside of the clamping plate 24. The rubber block 26 itself is elastic and has a cavity on its inner side, so that the retaining ring 53 presses against the clamping plate 24, causing the rubber block 26 to deform and change the angle of the clamping plate 24. Thus, the clamping plate 24 and the rubber block 26 together compress the rubber sleeve 61, causing the air inside the rubber sleeve 61 to be discharged into the rubber plug 41 through the vent valve 3, which is simultaneously located in the threaded fixing plate 21, the rubber plug 41, and the rubber sleeve 61, thereby making the rubber... The increased air pressure inside the plug 41 better supports the rubber plug 41, and the sealing strip 42 makes the connection between the device and the component tighter. The reinforcing rib 63 makes the rubber sleeve 61 more stable, improving its durability and pressure resistance. The support tube 44 provides internal support for the rubber plug 41, preventing it from shaking or shifting when inserted into the component's socket. When the device needs to be removed from the component, simply rotate the anti-slip block 52 in the opposite direction to rotate the threaded sleeve 51, thereby changing the relative position of the vent valve 3 and the rotating component 5. At this time, the excess air inside the rubber plug 41 will return to the rubber sleeve 61 through the vent valve 3, allowing the device to be easily removed from the component without wear due to excessive friction with the component.

[0040] 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.
