[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] like Figure 1 , Figure 2 As shown, the utility model provides an aviation connector plug, including a plug rubber core 1, a first pin 2, and a second pin 3. The plug rubber core 1 includes a first pin mounting portion 11 and a second pin mounting portion 12. The first pin mounting portion 11 is formed by the second pin mounting portion 12 extending outwardly along its axial direction. The first pin 2 is arranged on the first pin mounting portion 11, and the second pin 3 is arranged on the second pin mounting portion 12.

[0031] like Figure 1 , Figure 3As shown, in this embodiment, the first pin mounting portion 11 is formed by the second pin mounting portion 12 extending outward along the axial direction thereof, that is, there is a height difference between the first pin mounting portion 11 and the second pin mounting portion 12, which can effectively extend the creepage distance between the first pin 2 and the second pin 3. In a high voltage environment, a longer creepage distance helps to avoid arc discharge and reduce the risk of breakdown, so that the voltage resistance level of the utility model is better. In addition, the first pin mounting portion 11 protrudes from the second pin mounting portion 12, which can effectively isolate the short-circuit current, so that the utility model is not easy to cause a short circuit.

[0032] like Figure 1 As shown, in this embodiment, the first pin mounting portion 11 includes a first base 111 and a second base 112 connected to the first base 111, a portion of the first pins 2 are plugged into the first base 111, and another portion of the first pins 2 are plugged into the second base 112, and there is a height difference between the upper end surface of the first base 111 and the upper end surface of the second base 112, which can extend the creepage distance between the first pins 2 on the first base 111 and the first pins 2 on the second base 112, and improve the high voltage resistance of the aviation plug connector. In addition, the first base 111 is arranged around the outside of the second base 112, and the surrounding layout can provide better physical isolation, reduce interference between adjacent first pins 2, and may also help to improve the overall structural strength and stability.

[0033] like Figure 1 , Figure 2 As shown, in this embodiment, a plurality of first plug holes 113 are provided on the first pin mounting portion 11, and a plurality of first pins 2 are plugged into the corresponding first plug holes 113. In addition, the first pin mounting portion 11 has an annular boss 114 protruding outward at the opening position corresponding to each first plug hole 113, which extends the distance between two adjacent first pins 2 along the surface of the first pin mounting portion 11, effectively extending the creepage distance, improving the withstand voltage level of the utility model, making it less likely to be broken down, improving the electrical safety of the aviation plug connector plug, and reducing the risk of failure caused by high voltage.

[0034] like Figure 1 , Figure 2As shown, in this embodiment, a plurality of second sockets 121 are provided on the second pin mounting portion 12, and a plurality of second pins 3 are plugged into the corresponding second sockets 121. In addition, the opening position of each second socket 121 of the second pin mounting portion 12 is recessed inward to form an annular groove 122, which extends the distance between two adjacent second pins 3 along the surface of the second pin mounting portion 12, effectively extending the creepage distance, improving the withstand voltage level of the utility model, making it less likely to be broken down, improving the electrical safety of the aviation connector plug, and reducing the risk of failure caused by high voltage. In addition, the annular boss 114 on the first pin mounting portion 11 is different from the annular groove 122 on the second pin mounting portion 12, which is convenient for staff to identify and check the first pin 2 and the second pin 3, and simplifies the installation and maintenance replacement process.

[0035] like Figure 3 , Figure 4 As shown, in the present embodiment, thrust steps 13 are provided inside the first jack 113 and inside the second jack 121, and the thrust steps 13 can limit the first pin 2 and the second pin 3, ensuring that the first pin 2 and the second pin 3 will not be over-inserted after being inserted into the corresponding jacks, so that the plug rubber core 1 will not be exposed after one end of the first pin 2 is inserted into the first jack 113, and the plug rubber core 1 will not be exposed after one end of the second pin 3 is inserted into the second jack 121, so that the first pin 2 and the second pin 3 are easily plugged into the pins in the aviation plug connector socket, thereby realizing the electrical connection between the aviation plug connector socket and the aviation plug connector plug. In addition, the outer side of the first pin 2 and the outer side of the second pin 3 are both provided with an undercut structure 21, which interferes with the plug rubber core 1, that is, the undercut structure 21 is inserted into the plug rubber core 1, which can prevent the first pin 2 and the second pin 3 from withdrawing, and play a limiting role, preventing the first pin 2 and the second pin 3 from rotating, ensuring that the first pin 2 and the second pin 3 maintain the correct position and direction to maintain a stable electrical connection. In addition, the thrust step 13 and the undercut structure 21 improve the connection stability between the aviation plug connector plug and the aviation plug connector socket, and reduce the risk of unstable connection or disconnection due to vibration or mechanical stress.

[0036] In this embodiment, the first pin 2 is a signal pin, which is mainly used to transmit control signals, data signals or sensor signals, etc. The second pin 3 is a power pin, which is responsible for transmitting power and providing the required electrical energy for the device. That is, the plug core 1 is provided with a signal pin and a power pin, so that the signal and power can be transmitted simultaneously in one connector, thereby improving the compactness and functionality of the design. In addition, compared with the existing power supply aviation plug and signal aviation plug that require two sets of connectors, the utility model can realize that the power supply aviation plug and the signal aviation plug only use one set of connectors, reducing the need to manufacture and assemble two different sets of connectors, simplifying the assembly process, and saving costs.

[0037] In this embodiment, the diameter of the first pin 2 is smaller than the diameter of the second pin 3. The diameter of the first pin 2 can be designed to be 0.7 mm, and the diameter of the second pin 3 can be designed to be 2 mm. Of course, in actual design, the diameter of the first pin 2 and the diameter of the second pin 3 can be designed according to actual needs.

[0038] like Figure 1 , Figure 3 As shown, in this embodiment, the number of first pins 2 on the first base 111 is 6, the number of first pins 2 on the second base 112 is 5, and the number of second pins 3 on the second pin mounting portion 12 is 4, that is, the utility model is a 15-pin aviation plug connector plug. Of course, in actual design, the number of first pins 2 and the number of second pins 3 can be designed according to actual needs.

[0039] like Figure 5 , Figure 6 As shown, in this embodiment, the plug rubber core 1 has an insulating function, and a plug nut 8 is sleeved on the outside of the plug rubber core 1 to facilitate the connection of the plug rubber core 1 with the aviation plug connector socket. After the first pin 2 and the second pin 3 are inserted into the corresponding jacks, one end of the first pin 2 and one end of the second pin 3 are arranged inside the plug rubber core 1, and the other end of the first pin 2 and the other end of the second pin 3 protrude from the plug rubber core 1, and the end of the plug rubber core 1 that exposes the first pin 2 and the second pin 3 is molded with a PVC colloid 4 through the first injection molding, and the outer side of the PVC colloid 4 is sleeved with a plug shell 5 to protect the PVC colloid 4. In addition, the end of the PVC colloid 4 away from the plug rubber core 1 is connected to a cable 6, and the outer side of the cable 6 is molded with a plastic tail net 7 through the second injection molding, which can increase the stability of the connection between the PVC colloid 4 and the cable 6.
