Description

Technical Field

[0001] This utility model relates to signal connectors, specifically to a connector with a rotary snap-fit ​​structure. Background Technology

[0002] With the rapid development of electronic information technology, RJ45 connectors have been widely used in fields such as network communication. However, most RJ45 connectors on the market currently lack waterproof functionality. In some specialized industries, such as LED displays, equipment often needs to operate outdoors or in humid environments, placing higher demands on the waterproof performance of connectors.

[0003] To meet waterproofing requirements, most existing technologies achieve waterproofing by adding a waterproof box or nut housing. However, this approach has significant drawbacks. On the one hand, the added waterproof box or nut housing makes the overall connector structure bulky, which is not conducive to the miniaturization and lightweight design of the device. On the other hand, in actual use, the insertion and removal operations are inconvenient, requiring more time and effort for installation and disassembly, reducing work efficiency and making it difficult to meet the needs of rapid connection and disconnection.

[0004] Therefore, developing an RJ45 connector that has both good waterproof performance and is easy to plug and unplug is of great practical significance. Utility Model Content

[0005] The purpose of this invention is to provide a connector with a rotary snap-fit ​​structure to solve the problems of bulky waterproof structure and inconvenient insertion and removal of existing RJ45 connectors, so as to achieve quick insertion and removal and reliable waterproofing, thereby improving the practicality and ease of use of the connector.

[0006] To solve the above-mentioned technical problems, the present invention achieves this through the following solution: The present invention provides a connector with a rotary snap-fit ​​structure, including a plug and a socket that can be plugged into each other. The plug and socket are provided with a snap-fit ​​structure that can automatically rotate to interlock after plugging in and can be manually rotated in the opposite direction to disengage from the interlock.

[0007] Furthermore, the fastening structure includes:

[0008] A rotatable locking ring located at the plug end;

[0009] A self-resetting structure is provided in the plug. This self-resetting structure is connected to the locking ring drive and can drive the locking ring to rotate and reset. After the socket end and the locking ring are inserted, the locking ring is driven to rotate by an angle through the self-resetting structure, so that the socket and the locking ring are interlocked.

[0010] Furthermore, the self-resetting structure includes:

[0011] The plug fixing part has a concave ring on the outer wall of its port and multiple partitions in the concave ring. The multiple partitions divide the concave ring into multiple arc grooves. The port of the plug fixing part also has a break that communicates with the concave ring.

[0012] A spring is placed within an arc-shaped groove.

[0013] A triangular buckle is provided on the inner wall of the locking ring. The locking ring is rotatably connected to the port of the plug fixing part, and the right angle surface of the triangular buckle abuts against one end of the spring.

[0014] Furthermore, one of the multiple arc grooves is provided as a limiting groove to restrict the rotation angle of the locking ring;

[0015] The inner wall of the locking ring is provided with a limiting protrusion, which is restricted to move within the limiting groove.

[0016] Furthermore, the outer wall of the socket's insertion end is provided with at least two L-shaped grooves;
