Description

Technical Field

[0001] This utility model relates to the field of plug technology, and in particular to an aviation plug. Background Technology

[0002] In the field of electrical connections, aviation connectors are key components for signal and power transmission, and their performance and ease of installation are of paramount importance. With the continuous development of electronic technology, the requirements for aviation connectors are also increasing.

[0003] Currently, some aviation connectors have numerous problems. They have low modularity, complex component connections, and unclear division of labor, resulting in time-consuming and labor-intensive assembly and maintenance processes, increasing production costs and maintenance difficulty. When a fault occurs and repair is needed, large-scale disassembly is required. The connection between the retaining ring and the housing / cab bracket is unstable and easily falls off when subjected to external pulling or vibration, affecting the fixation of the female core component and consequently affecting the stability of signal and power transmission. This poses a significant safety hazard in fields with extremely high stability requirements, such as aerospace. The fixing method between the female core component and the housing is not ideal, and it is prone to shaking and shifting after installation, increasing contact resistance and leading to increased signal loss during transmission. In addition, the connector design is not user-friendly, requiring special tools or professional skills for installation, increasing installation time and cost. Moreover, the overall structure is not compact enough, limiting installation in small cabinets. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an aviation plug that is modular in structure, stable in connection, convenient in assembly and maintenance, reliable in electrical performance and easy to install.

[0005] To achieve the above objectives, this utility model employs an aviation plug comprising a housing containing a female core assembly. One end of the housing has a connection port, and the other end has a slot for inserting the female core assembly. A retainer is provided at one end of the slot, mounted on the bottom of the housing. The retainer has a corresponding slot in the slot, and a retaining ring is provided on the retainer. Both sides of the retainer have first cylinders for the retaining ring to rotatably engage with, the first cylinders being located at the ends of the retainer and fixedly connected to it. Above the corresponding first cylinders, the housing has second cylinders fixedly connected to it. Both sides of the retaining ring engage with the first cylinders of the retaining ring, and both sides of the retaining ring also have ear slot structures, which are hooked onto the corresponding second cylinders.

[0006] The advantages of the above structure are as follows: By adopting a modular design including the shell, female core assembly, card tray, and card ring, the division of labor among the components is clear and the connection method is clear, which facilitates assembly and maintenance. The card tray has a first cylinder on both sides for the card ring to be rotatably fitted, and the ear groove structure on both sides of the card ring is hooked onto the corresponding second cylinder on the shell. This dual connection method enhances the connection stability between the card ring and the shell and card tray, so that the card ring is not easy to fall off when the aviation plug is subjected to external force pulling or vibration, ensuring the stable fixation of the internal female core assembly. One end of the shell has a slot for inserting the female core assembly, which, together with the card tray, limits the position of the female core assembly, so that the female core assembly can be accurately and firmly installed in the shell. Moreover, the overall structure, through reasonable design, reduces unnecessary material use while ensuring functionality, achieving the purpose of saving materials, and is also conducive to installation and layout in small cabinets.

[0007] This utility model is further configured as follows: the female core assembly includes a female base and a cover plate, with a receiving space formed between the female base and the cover plate. A plug-in assembly and terminal pieces are disposed within the receiving space. The plug-in assembly includes a connecting post, a spring piece mounted on the connecting post, and a direct-insertion button inserted into the spring piece. The female base and the cover plate are connected by a latching protrusion on the female base and a latching groove on the cover plate. The female base and the cover plate are connected by a latching protrusion and a latching groove. Compared to traditional threaded connections or welding methods, this latching method has the advantages of tight connection and less susceptibility to loosening. In the plug-in assembly, the spring piece is mounted on the connecting post, and the direct-insertion button is inserted into the spring piece, ensuring good electrical contact. The elasticity of the spring piece allows for stable electrical contact between the direct-insertion button and the spring piece, reducing contact resistance, minimizing signal transmission loss, improving electrical performance, and making it more reliable in use.

[0008] This utility model is further configured such that both ends of the female connector are connected to the housing via screws. The connection between the two ends of the female connector and the housing via screws allows for easy assembly and disassembly using appropriate screwdrivers, reducing the difficulty of assembly and disassembly and facilitating operations during maintenance or component replacement.

[0009] This utility model is further configured with a threaded groove connection port. When connecting via the threaded groove connection port, simply align the threaded portion with the threaded interface of the corresponding device or cable, and then tighten it by rotation. No complex tools or professional skills are required; ordinary operators can easily complete the installation. Attached Figure Description
