Description

Technical Field

[0001] The present application relates to the technical field of electronic connectors, and in particular to an anti-retraction and waterproof structure of a connector. Background Art

[0002] Aviation plugs, also known as aviation connectors, are a type of connector that is widely used in a variety of applications, especially in environments that require stable and reliable connections. They are commonly used in aviation, industrial automation, medical equipment, and other high-demand electronic systems.

[0003] In aviation plugs and other types of advanced connectors, waterproofing is a very important feature that ensures the reliability and functionality of the connector under various environmental conditions. Waterproof structure refers to the feature in the connector design that prevents water, moisture or other liquids from entering the connector. It is usually achieved by installing a rubber seal or gasket at the joint of the connector. When the connector is assembled, the seal is compressed to form a tight barrier to prevent moisture from entering. However, since the joint of the connector shell may be disengaged due to external force or vibration, it is easy to cause poor stability and waterproof performance of the connector.

[0004] Therefore, based on the above problems, the prior art needs to be improved. Utility Model Content

[0005] The purpose of this application is to improve the connection stability and waterproof performance of the connector housing joint.

[0006] The above-mentioned technical purpose of the present application is achieved through the following technical solutions: a connector anti-retraction and waterproof structure, comprising a first shell, to which a second shell is detachably connected, a first installation channel is hollow in the first shell, and a second installation channel is hollow in the second shell; an inner wall of the first installation channel is concave at one end close to the second shell to form a mounting groove, and the mounting groove is provided with an internal thread; the second shell comprises a receiving part and a mounting part, the receiving part is annularly arranged on the mounting part, the mounting part is provided with an external thread, the receiving part is provided with a first gasket, the first gasket is fitted on the mounting part, a first groove is concave in the mounting groove, the inner wall of the first groove can cooperate with the mounting part to clamp the first gasket, a first clamping part is provided on the receiving part, and a second clamping part is provided on the second shell, the first clamping part cooperates with the second clamping part to clamp, so as to limit the rotation of the first shell relative to the second shell.

[0007] By adopting the above technical solution, through the use of the first gasket and the tight structural fit between the two shells, it is possible to effectively prevent the intrusion of moisture and other environmental factors, protect the internal circuit connection, and thus improve the overall waterproof performance of the plug. The use of the internal and external thread matching method not only makes the connection between the first shell and the second shell tighter, but also effectively disperses the pressure at the connection, improving the stability and durability of the plug during use. Through the matching snap-fit ​​design of the first clip and the second clip, the rotation of the shell due to misoperation can be effectively prevented, thereby ensuring the safety and reliability of the electrical connection. The gasket and clip design in the structure not only improves the waterproof performance, but also reduces the wear caused by frequent operation or environmental factors, prolongs the service life of the product, and improves the connection stability and waterproof performance of the connector shell joint.

[0008] Optionally, the first clamping member is a clamping groove formed by a concave portion of the receiving portion, and the second clamping member is a buckle protruding from one end of the second shell close to the first shell.

[0009] By adopting the above technical solution, the combination of the concave slot and the raised buckle can accurately fix the relative position between the two shells. Such a physical locking mechanism provides additional protection in terms of mechanical strength and reduces the loose connection caused by vibration or impact. This slot and buckle design allows users to complete the assembly and disassembly of the plug more quickly without the use of tools, which is convenient for quick operation on site. Because the buckle design can provide an audible "click" sound to form damping, the user can intuitively know that the connection has been firmly completed. Instant feedback helps reduce electrical failures caused by improper connections.

[0010] Optionally, a guide surface is provided on the second clamping member.

[0011] By adopting the above technical solution, through the guiding effect of the guide surface of the second clip, it is convenient for the user to match the texture of the internal and external threads, so that the user can easily connect the first shell and the second shell, avoiding excessive clamping of the first clip and the second clip, which makes it impossible to connect the knob; after completing the connection between the first shell and the second shell, the design of the guide surface also plays a role in limiting misoperation, preventing the possibility of separation of the first shell and the second shell by the reverse knob due to misoperation by the user, improving the connection stability of the first shell and the second shell, and making the first clip and the second clip stably clamped, thereby improving the convenience of use and connection stability of the plug.

[0012] Optionally, there are multiple first clamping members.

[0013] By adopting the above technical solution, the design of multiple first clamping parts can realize clamping at more positions, thereby enhancing the stability of the connection. The pressure of the connection part can be effectively dispersed, the risk of loose connection is reduced, and the overall reliability of the plug is improved. Through the design of multiple clamping points, even if some clamping points are loose or faulty, other clamping points can still maintain the connection, ensuring the reliability and durability of the connection. The design of multiple clamping points can better resist the influence of external vibration and impact, and improve the stability of the connection in harsh environments.

[0014] Optionally, there are multiple second clamping members.

[0015] By adopting the above technical solution, the design of multiple second clamping parts can realize clamping at more positions, thereby enhancing the stability of the connection. The pressure of the connection part can be effectively dispersed, the risk of loose connection is reduced, and the overall reliability of the plug is improved. Through the design of multiple clamping points, even if some clamping points are loose or faulty, other clamping points can still maintain the connection, ensuring the reliability and durability of the connection. The design of multiple clamping points can better resist the influence of external vibration and impact, and improve the stability of the connection in harsh environments.

[0016] Optionally, a second gasket is mounted on the mounting portion, a second groove is formed in the mounting groove, and a groove wall of the second groove cooperates with the mounting portion to clamp the second gasket.

[0017] By adopting the above technical solution, the provision of the second gasket can further improve the sealing performance of the plug. Through the design of the second groove, the second gasket can be better clamped with the mounting portion to form a tighter sealing effect, prevent liquid or impurities from entering the connection part, and improve the waterproof performance of the plug. The addition of the second gasket can add additional gasket support to the connection part, effectively disperse the pressure at the connection, and improve the stability and durability of the connection. This helps to prevent loosening or instability during the connection process and ensure the firmness of the connection. The presence of the second gasket can effectively absorb vibration and shock, and reduce the impact of external environmental factors on the connection. This helps to improve the stability and reliability of the plug in harsh environments and extend the service life of the plug.

[0018] Optionally, a shaft sleeve is provided on the second washer, and the shaft sleeve is passed through the first installation channel.

[0019] By adopting the above technical solution, a more stable connection is formed between the second gasket and the first installation channel through the setting of the shaft sleeve. The shaft sleeve increases the contact area with the inner wall of the first installation channel, preventing external moisture and dust from entering the shaft sleeve through the gap between the shaft sleeve and the inner wall of the first installation channel. The setting of the shaft sleeve can effectively reduce the friction and wear between the installation object and the first installation channel. The service life of the plug and the connection parts is extended, the frequency of maintenance and replacement is reduced, and the overall cost is reduced.

[0020] Optionally, a receiving groove is provided on the second washer for receiving the shaft sleeve.

[0021] By adopting the above technical solution, through the cooperation between the receiving groove and the sleeve, the second washer can more firmly fix the position of the sleeve, thereby enhancing the stability of the connection. This helps to prevent the sleeve from falling off or shifting due to swinging or shaking during use, ensuring the firmness of the connection component. Through the cooperation of the receiving groove, the sleeve can be more firmly connected to the second washer, reducing friction and wear during the connection process. This helps to extend the service life of the sleeve and the second washer, reduce the frequency of maintenance and replacement, and reduce the overall cost. The design of the receiving groove can ensure a tighter connection between the second washer and the sleeve, and improve the waterproof performance. This helps to prevent liquid or impurities from entering the connection part, protect the circuit safety inside the plug, and improve the reliability of the plug.

[0022] In summary, this application has at least the following beneficial effects:

[0023] 1. Through the use of the first gasket and the tight structural fit between the two shells, the intrusion of moisture and other environmental factors can be effectively prevented, the internal circuit connection can be protected, and the overall waterproof performance of the plug can be improved. The use of internal and external thread matching not only makes the connection between the first shell and the second shell tighter, but also effectively disperses the pressure at the connection, improving the stability and durability of the plug during use. Through the matching snap-fit ​​design of the first clip and the second clip, the rotation of the shell due to misoperation can be effectively prevented, thereby ensuring the safety and reliability of the electrical connection. The gasket and clip design in the structure not only improves the waterproof performance, but also reduces the wear caused by frequent operation or environmental factors, prolongs the service life of the product, and improves the connection stability and waterproof performance of the connector shell joint.

[0024] 2. Through the guiding effect of the guide surface of the second clamping part, it is convenient for the user to match the texture of the internal and external threads, so that the user can easily connect the first shell and the second shell, avoiding excessive clamping of the first clamping part and the second clamping part, which may cause the knob to be unable to connect; after the first shell and the second shell are connected, the design of the guide surface also plays a role in limiting misoperation, preventing the possibility of the first shell and the second shell being separated by the reverse knob due to misoperation by the user, improving the connection stability of the first shell and the second shell, and making the first clamping part and the second clamping part stably clamped, thereby improving the convenience of use and connection stability of the plug.

[0025] 3. Through the cooperation of the receiving groove and the sleeve, the second washer can more firmly fix the position of the sleeve, thereby enhancing the stability of the connection.
