Description

Technical Field

[0001] This utility model relates to a connector, and more particularly to a nylon aviation-grade insert nut. Background Technology

[0002] Electronic connectors, also known as circuit connectors or electrical connectors, are conductor devices that bridge two conductors in a circuit, allowing current or signals to flow from one conductor to the other. They are widely used in various electrical circuits to connect or disconnect current or signals. This connection can be temporary and easy to plug and unplug, or it can be a permanent junction between electrical devices or wires. For connectors with direct thread connections, one end is directly mounted on the active device; however, the angle is difficult to adjust during operation, and excessive force can easily cause local misalignment, thus affecting its use.

[0020] like Figures 1-6As shown, a nylon aviation-grade rear nut includes a rear connector 1, a front connector 2, a union 3, and a front cover 4, assembled sequentially along the same axis. The rear connector 1 is provided with a threaded tightening nut 5. After initial assembly, the connection is strengthened by tightening the nut 5 to prevent loosening. The design of the tightening nut 5 eliminates the need for a complex structural layout, facilitating production and processing. The rear connector 1 and the front connector 2, as well as the front connector 2 and the front cover 4, are all connected by threads. The union 3 is sleeved on the front connector 2, and is threadedly connected to the rear connector 1. The front connector 2 is axially locked by the union 3. The threaded connection is convenient to operate, provides a tight connection, and offers good electrical sealing, meeting design requirements. The design of the union 3 utilizes a union connection method, avoiding excessive length and enhancing the structural strength of critical components. The union form, i.e., being threaded onto the connector and fixed, combined with axial locking, ensures that critical components are securely and reliably held within it.

[0021] The front connector 2 and the rear connector 1 are equipped with electrical connection components, which include a main positioning seat 6, a secondary positioning seat 7, a supplementary positioning seat 8, an open pipe 9, a closed pipe 10, and a sealing ring 11. The open pipe 9 is a through structure along the axis, and the closed pipe 10 is closed at one end. The open pipe 9 and the closed pipe 10 are electrically connected. The secondary positioning seat 7 is located on both axial sides of the main positioning seat 6, and the supplementary positioning seat 8 is located on the side of the main positioning seat 6 and the secondary positioning seat 7 near the closed pipe 10. Between the main positioning seat 6, the secondary positioning seat 7, and the supplementary positioning seat 8, there are several positioning holes 12 for the opening pipe 9 or the closing pipe 10 to pass through. The opening pipe 9 has a sleeve portion 13 at the end near the closing pipe 10. The inner diameter of the sleeve portion 13 is greater than or equal to that of the closing pipe 10, and the outer diameter of the sleeve portion 13 is greater than that of the opening pipe 9. Each of the opening pipe 9 and the closing pipe 10 is provided with a separating limiting ring 14. The sealing ring 11 is sleeved on the outer wall at the junction of the main positioning seat 6, the secondary positioning seat 7, and the supplementary positioning seat 8. The split design of the electrical connection assembly is conducive to the assembly of components made of different materials, and the design is compact and tightly connected. During assembly, due to the design of each node, there are matching sealing rings 11 and connecting structures to enhance the tightness of the connection. The sleeve portion 13 is easy to process and manufacture, and can also strengthen the local structural strength. The design of the limiting ring 14 is conducive to the stable installation of each positioning group, and together with the design of the sealing ring 11, it meets the design and usage requirements.

[0022] The front connector 2 has a retaining flange 15 on its outer side wall, which is simple and reliable in design and meets the requirements for live-fit connection. The sleeve part 13 has a slot 16 on its outer wall for easy assembly. Both the front connector 2 and the rear connector 1 have positioning strips 17 on their inner walls, and the electrical connection assembly has positioning grooves 18 corresponding to the positioning strips 17. The positioning strips 17 and positioning grooves 18 are fitted and fixed together. The design of the positioning strips 17 and positioning grooves 18 can enhance the tightness of the connection and reduce the impact of factors such as vibration. The rear connector 1 also has a mounting plate 19 on its inner wall, and the front connector 2 also has a mounting groove 20 on its outer wall. The mounting plate 19 and mounting groove 20 are fitted and fixed together. Furthermore, by using a fitting method for the components of the main body, they can be connected into a tight whole, which is beneficial for safe use and improves service life.

[0023] The open connector 9 and the closed connector 10 have oblique cuts 21 at their outer ends to facilitate the insertion of large-strand wires and reduce installation difficulty. The electrical connection assembly has circumferentially arranged positioning blocks 22 on its outer wall, and the front connector 2 and the rear connector 1 have matching limiting grooves 23 on their inner walls. This staggered arrangement of positioning and fitting structures improves structural stability and simplifies assembly. The diameter of the front cover 4 gradually increases from one end to the other. One end of the front cover 4 has an elastically clamping constriction portion 24, which also has a tightening nut 25. The front cover 4 provides ample internal space for easy wiring without affecting the tightening and fixing at the constriction portion 24. The constriction portion 24 has evenly spaced notches 26 along its circumference, and a protective sleeve 27 is provided inside. A limiting strip 28 is also provided at the constriction portion 24 to prevent the protective sleeve 27 from detaching. The notch 26 is one embodiment that reduces stiffness through segmentation to achieve the required elastic force.
