Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically relating to an aviation connector and its male connector assembly. Background Technology

[0002] Aviation connectors are a type of connector, often simply called aviation plugs or aviation heads. They consist of male and female connector assemblies that interlock, and are electromechanical components used to connect electrical circuits. Existing aviation connector male assemblies typically include a cylindrical shell, a cylindrical core inserted into the shell, and pins inserted into the core. During assembly, the pins are first inserted into the core, then the core is inserted into the shell and rotated circumferentially relative to the shell to a predetermined position. Finally, the shell is riveted so that internal fasteners penetrate the core, securing it in place. However, the assembly process is inefficient because rotating the core circumferentially relative to the shell to the predetermined position is done manually. This is prone to oversight, leading to misalignment of the pins and making it difficult to connect the male and female connectors. In severe cases, this can cause wiring misalignment during use, resulting in damage to electronic components. Utility Model Content

[0028] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0029] This utility model embodiment first provides a male connector assembly for an aviation connector, see reference. Figures 1 to 5 The male connector assembly 100 mainly includes a male connector housing 1, a male connector core 2, and a male connector pin 3. The male connector core 2 is inserted into the male connector housing 1, and the male connector pin 3 is inserted into the male connector core 2.

[0030] Specifically, the male head shell 1 is provided with a first cavity 11 and a second cavity 12 that are interconnected along its axial direction. The first cavity 11 is cylindrical, one side of the inner wall of the second cavity 12 is formed as a V-shaped groove surface 121, and the remaining part of the inner wall of the second cavity 12 is formed as an arc surface 122.

[0031] Specifically, the male connector core 2 includes a male connector core body 21 and an extension 22 connected to each other. The male connector core body 21 has a shape adapted to the first cavity 11 and is inserted into the first cavity 11. The extension 22 is connected to the end face of the male connector core body 21 facing the second cavity 12, and the extension 22 has a shape adapted to the second cavity 12 and is inserted into the second cavity 12. That is, the outer side wall of the extension 22 has a V-shaped protruding surface 221 corresponding to the V-shaped groove surface 121 and an arc-shaped surface 222 corresponding to the arc surface 122.

[0032] Specifically, the male PIN pin 3 is inserted into the male core 2, the first end of the male PIN pin 3 extends from the end face of the male core body 21 to the outside of the male outer shell 1, and the second end of the male PIN pin 3 extends from the end face of the extension portion 22 to the second cavity 12.

[0033] As shown in the above embodiment, the male connector assembly 100 has a V-shaped groove surface 121 in the second cavity 12 of the male connector housing 1, and an extension 22 that is inserted into the second cavity 12. The extension 22 has a shape adapted to the second cavity 12, that is, the outer wall of the extension 22 has a V-shaped protruding surface 221 corresponding to the V-shaped groove surface 121. During assembly, the V-shaped groove surface 121 of the second cavity 12 and the V-shaped protruding surface 221 of the extension 22 form a guide mechanism for insertion assembly. In the circumferential direction of the male connector core 2, the extension 22 can only be inserted into the second cavity 12 to complete the assembly when the V-shaped protruding surface 221 corresponds to the V-shaped groove surface 121. After the extension 22 is inserted into the second cavity 12, the male connector core 2 cannot rotate relative to the male connector housing 1, ensuring that the male connector core 2 can be fixed in the accurate assembly position. Based on the structure of the male connector assembly 100 described above, during assembly, the alignment and fixation are achieved through a guide mechanism composed of the V-shaped groove surface 121 and the V-shaped protruding surface 221. This eliminates the need for manual inspection to verify whether the male connector core 2 has rotated to the predetermined position relative to the outer shell in the circumferential direction. As a result, the male connector core 2 can be accurately and quickly inserted into the male connector outer shell 1, which improves the assembly efficiency of the male connector assembly 100 and increases the product yield. It also greatly avoids various defects caused by human negligence that prevents the core from being assembled to the predetermined position.

[0034] In the specific design, the inner diameter of the first cavity 11 is larger than the inner diameter of the second cavity 12, and correspondingly, the outer diameter of the male core body 21 is larger than the outer diameter of the extension 22.

[0035] In a specific embodiment, the length of the extension 22 in the axial direction of the male connector core 2 is preferably set to 0.6mm to 1.0mm.

[0036] For specific details, please refer to the following: Figure 5 At the connection interface between the first cavity 11 and the second cavity 12, the height by which the center point of the V-shaped groove surface 121 protrudes from the inner wall of the first cavity 11 (e.g.) Figure 5 The dimension d) is preferably set to 0.28mm to 0.35mm. Further, the included angle between the two inclined surfaces of the V-shaped groove surface 121 (e.g., ...) Figure 5 The angle α in the middle is preferably set to 100° to 150°.

[0037] In the specific design, there are multiple male pins 3, which are inserted into the male connector core 2 at intervals. In this embodiment, as shown... Figure 2As shown, five male connector pins 3 are inserted into the male connector core 2. In some other embodiments, the number of male connector pins 3 can be set to a range of 2 to 8, depending on the specifications of the male connector assembly 100.

[0038] Based on the male connector 100 provided in the above embodiments, this utility model also provides an aviation connector, see reference. Figures 6 to 9 and combined Figures 1 to 5 The aviation connector includes a female connector assembly 200 and a male connector assembly 100 as described in the above embodiment. The female connector assembly 200 includes a female connector housing 4, a female connector core 5, and female connector pins 6. The female connector core 5 is inserted into the female connector housing 4, and the female connector pins 6 are inserted into the female connector core 5. The number of female connector pins 6 corresponds to the number of male connector pins 3.

[0039] The female connector core 5 includes a female connector core body 51 and a plug portion 52 connected to each other. The plug portion 52 has a shape adapted to the second cavity 12. When the female connector assembly 200 and the male connector assembly 100 are connected to each other, the plug portion 52 is inserted into the second cavity 12, so that the female connector pin 6 and the male connector pin 3 are connected to each other in a one-to-one correspondence.

[0040] The above description is only a specific embodiment of this application.
