Description

Technical Field

[0001] The utility model relates to the technical field of industrial connectors, in particular to a circular waterproof connector. Background Art

[0002] Industrial connectors are specialized connectors used to connect industrial equipment, machines or systems. They provide a reliable method to transmit power, signals or data and allow devices to communicate or share resources. Connectors usually consist of a plug and a socket. The socket is the receiving part of the connector, usually designed as a recessed structure, containing a set of electrodes or contact points that match the pins of the plug. The connector socket is responsible for receiving and connecting the plug to transmit power, signals or data to the corresponding device or circuit.

[0003] However, the various components of the existing connector socket are usually fixedly connected or connected by snaps, so auxiliary tools such as screwdrivers are usually needed to disassemble the connector socket, which makes it inconvenient to quickly repair it. Utility Model Content

[0008] Through the above technical solution, through the double waterproof gasket design, it is possible to effectively prevent water, liquid or moisture from invading the interior of the connector socket, protecting the connector and its internal components from water damage.

[0009] Furthermore, a first thread circle is arranged on the outer surface of the shell, and a second thread circle is arranged on the inner side of the nut.

[0010] Through the above technical solution, the shell and the nut can be threadedly connected by using the first thread ring and the second thread ring, so that the first waterproof gasket is stably sandwiched between the shell and the rope chain. The connector socket can be fixed on the equipment or at a specific position through the rope chain to prevent the connector from accidentally falling or losing, especially in a moving or vibrating environment, the rope chain can effectively prevent the connector from falling off.

[0011] Furthermore, the outer surface of the shell is provided with card slots, and the card slots are symmetrically distributed with respect to the transverse center line of the shell.

[0012] Through the above technical solution, the slot is used to dock with the protrusion.

[0014] Through the above technical solution, the shell and the dust cap can be quickly connected or disassembled by utilizing the threaded connection between the shell and the dust cap, which is beneficial to improving the convenience of connecting and disassembling the shell and the dust cap.

[0015] Furthermore, a plurality of pins are provided, and the pins are symmetrically distributed about the longitudinal center line of the shell.

[0016] Through the above technical solution, the main function of the pin is to receive the plug inside the connector socket. When the plug is inserted into the connector socket, the pin will connect with the corresponding contact point on the plug to establish a transmission channel for electrical signals, data signals or power, and different numbers of pins can be designed according to different usage requirements of the socket.

[0017] Furthermore, the first waterproof gasket is in a circular ring structure, and the outer diameter of the first waterproof gasket is equal to the maximum diameter of the shell.

[0018] Through the above technical solution, it is convenient to sleeve the first waterproof gasket on the outer surface of the shell, so as to improve the waterproof performance of the shell through the first waterproof gasket.

[0019] Furthermore, the second waterproof gasket is in a cylindrical structure, the diameter of the second waterproof gasket is equal to the inner diameter of the dustproof cap, and the second waterproof gasket is located inside the dustproof cap.

[0020] Through the above technical solution, the second waterproof gasket can be used to improve the sealing performance of the connection between the shell and the dustproof cap, thereby improving the waterproof performance of the connector socket.

[0021] Furthermore, the inner wall of the dustproof cap is provided with two protrusions, and the protrusions correspond to the card slots one by one.

[0022] Through the above technical solution, the design of the slot and the protrusion can help the dust cap to be correctly positioned on the shell, ensuring that the dust cap is correctly installed and fits tightly on the shell, thereby improving the accuracy and stability of the installation of the dust cap and the shell.

[0023] Furthermore, a through groove is provided inside the dust cap, and two through grooves are provided, and the through grooves are symmetrically distributed about the transverse center line of the dust cap.

[0024] Through the above technical solution, the through groove helps to reduce the air pressure inside the dust cap and prevent the accumulation of air pressure that makes the dust cap difficult to remove. When the connector socket is not used for a long time, internal air pressure accumulation may occur. The presence of the through groove can alleviate this situation and make disassembly easier.

[0025] Furthermore, the outer surface of the dust cap is an uneven wavy structure.

[0026] Through the above technical solution, the wavy concave-convex structure can increase the friction between the dust cap and the fingers, making it easier to grasp and remove, and helping users to easily hold the dust cap in a humid or greasy environment to ensure quick and stable removal.

[0027] Compared with the prior art, the utility model provides a circular waterproof connector, which has the following beneficial effects:

[0028] In the utility model, the double waterproof gasket design can effectively prevent water, liquid or moisture from invading the interior of the connector socket, protecting the connector and its internal components from water damage, and through the threaded connection between the shell and the nut and the dustproof cap, the shell can be quickly connected and disassembled with the first waterproof gasket, the nut, the second waterproof gasket and the dustproof cap respectively, which not only extends the service life of the connector socket, but also simplifies the maintenance process of the connector socket.
