Description

Technical Field

[0001] This utility model relates to the field of aviation connector technology, specifically to an aviation connector female head. Background Technology

[0002] In existing technologies, the structure of aviation connector females typically includes components such as a shell, internal metal terminals, a sealing ring, and a wiring harness. The processing and assembly process generally involves: the shell being formed using injection molding; the internal metal terminals being formed by copper stamping and then soldered to the wiring harness; the metal terminals being inserted into the shell's slots and sealed and fixed using a secondary injection molding process; and finally, the wiring harness being soldered to the PCB board to achieve circuit connection. The sealing ring is made using a rubber molding process to meet basic waterproof and dustproof requirements.

[0003] However, in the existing technology, the connection between the metal terminals and the PCB board needs to be transferred and soldered through the wire harness, which not only increases the cost of wire harness materials and soldering processes, leading to reduced production efficiency, but also poses a risk to contact reliability due to multiple soldering nodes. At the same time, the existence of the secondary injection molding sealing process further increases the complexity of the process and production costs, and the waterproof and dustproof performance is easily affected in long-term use or harsh environments. Utility Model Content

[0006] Furthermore, the buckle includes a base, a connecting plate, a vertical plate, and an inclined plate; the two bases are arranged opposite each other, the connecting plate is connected between the two bases, the vertical plate is connected above the base, and the inclined plate is connected between the two vertical plates, with the two vertical plates, the connecting plate, and the inclined plate forming a hollow section.

[0007] Furthermore, an annular portion is provided on the upper surface of the third flange portion, and four terminals are disposed within the annular portion.

[0008] Furthermore, the four terminals are arranged in a rectangular pattern.

[0009] This utility model has the following advantages: By designing the terminals as extended welding parts and directly welding them to the PCB board, this utility model eliminates the wire harness and wire harness welding process in the traditional structure, reducing material costs and process complexity, while reducing welding nodes to improve connection reliability; the shell adopts an integrated molding process, eliminating the secondary injection molding sealing process and further simplifying the production process; by adding a sealing ring to the bottom columnar part, in conjunction with the buckle to fix the PCB board, the waterproof and dustproof performance and structural stability of the product are effectively improved.

Detailed Implementation

[0013] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be pointed out that the following detailed description is illustrative and intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0014] Please see Figure 1 This utility model provides an aviation connector female, including a housing 1, a buckle 2, a terminal 3 and a sealing ring 4.

[0015] The outer shell 1 includes a bottom columnar portion 14 and a first flange portion 11, a second flange portion 12 and a third flange portion 13 arranged sequentially above the bottom columnar portion 14 from bottom to top. The outer shell 1 is integrally formed by injection molding, which eliminates the secondary injection molding sealing process in the traditional structure, simplifies the production process and reduces the process cost.

[0016] Terminal 3 is disposed on the third flange portion 13, and an extension welding portion 31 is connected above terminal 3. The extension welding portion 31 can be directly welded to the PCB board without the need for wire harness transfer, reducing wire harness material costs and welding processes, while also reducing the reliability risk of multi-node contact. Two clips 2 are symmetrically disposed at both ends of the third flange portion 13. The clips 2 can mechanically fix the PCB board, improving the structural stability of the connection between the connector and the PCB board. Two sealing rings 4 are disposed on the bottom columnar portion 14. The two sealing rings 4 are respectively located below the first flange portion 11 and between the second flange portion 12 and the third flange portion 13. Compared with the traditional single sealing ring design, the double sealing rings 4 can significantly improve waterproof and dustproof performance and adapt to harsher usage environments.

[0017] In this embodiment, the buckle 2 includes a base 21, a connecting plate 22, a vertical plate 23, and an inclined plate 25. The two bases 21 are arranged opposite to each other, the connecting plate 22 is connected between the two bases 21, the vertical plate 23 is connected above the base 21, and the inclined plate 25 is connected between the two vertical plates 23. The two vertical plates 23, the connecting plate 22, and the inclined plate 25 form a hollow part 24. The hollow part 24 can reduce the amount of material used and reduce the structural weight. At the same time, the inclined design of the inclined plate 25 facilitates the quick insertion and removal of the PCB board.

[0018] The upper surface of the third flange portion 13 is provided with an annular portion 15, and four terminals 3 are disposed within the annular portion 15. The four terminals 3 are arranged in a rectangular pattern, which conforms to the conventional design of PCB circuit layout and facilitates precise docking with the pads on the PCB.

[0019] During the assembly process, the metal terminal 3 is first integrally formed by copper stamping to form an extended welding part 31. Then, the terminal 3 is inserted into the slot of the third flange part 13 of the housing 1 according to the circuit design. The housing 1 is integrally formed by injection molding to complete the fixation. Next, the two sealing rings 4 are respectively fitted into the corresponding positions of the bottom columnar part 14. Finally, the entire connector is mechanically fixed to the PCB board by the buckle 2, and the extended welding part 31 of the terminal 3 is directly soldered to the pad of the PCB board to complete the circuit connection.

[0020] This invention achieves direct welding to the PCB board by optimizing the terminal structure, eliminating the need for wire harnesses and secondary injection molding processes, reducing costs and improving production efficiency; the combination of double sealing ring design and snap-fit ​​fixing structure enhances connection stability while ensuring waterproof and dustproof performance. The overall structure is simple and reliable, and is suitable for electronic equipment scenarios with high requirements for connection reliability and environmental adaptability.
