DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the adsorption diagram in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Generally, the components of the embodiment of the utility model described and shown in the adsorption diagram here can be arranged and designed in various different configurations.

[0028] In the following, some embodiments of the present application are described in detail in conjunction with the adsorption diagram. In the absence of conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0029] Please refer to Figures 1 to 4 As shown, an embodiment of the utility model provides an aircraft plug mother needle, comprising: a first section mother needle 101 and a second section mother needle 102 which are arranged integrally; the end of the second section mother needle 102 is provided with a petal structure 103 and an extension ring 105 in sequence; the petal structure 103 is at least three petals, and the same gap 104 is provided between every two of the petal structures 103; the end of the first section mother needle 101 is provided with a small column end 107 and an oblique groove 109 which are smaller in diameter than the first section mother needle 101 in sequence.

[0030] In the present embodiment, the problem that the traditional two-petal structure is prone to opening outward during long-term use, resulting in the pin being unable to fully connect to the mother pin, causing a virtual connection and poor contact, is solved by adding a petal structure 103 and an extension ring 105 outside the petal structure 103. Specifically, the petal structure 103 between the extension ring 105 and the second section of the mother pin 102, when the pin is inserted, the pin first enters the extension ring 105, and then reaches the position of the petal structure 103, and the pin is clamped by the structure of the petal structure 103 so that it can have a good electrical connection, thereby solving the problem of unstable insertion of the pin in the traditional structure using a two-petal structure; and the extension ring 105 of the present application makes the above-mentioned petal structure 103 supported by the extension ring 105 at one end and the second section of the mother pin 102 at the other end, thereby preventing the petal structure 103 from opening and deforming outward during long-term use, thereby causing a virtual connection of the pin. The small column end 107 with a smaller diameter than the female pin and the oblique groove 109 are arranged at the end of the first section of the female pin 101, so that the female pin can be well fixed in the aviation socket. The oblique groove 109 facilitates the welding of the female pin and the wire, thereby improving the stability and reliability of the connection.

[0031] Next, an aircraft insert pin in this exemplary embodiment will be further described.

[0032] In the embodiments of this application, refer to Figures 1 to 4 As shown, the first section of female needles 101 and / or the second section of female needles 102 are also provided with a limiting protrusion 106, and no matter the limiting protrusion 106 is located at the first section of female needles 101 or the second section of female needles 102, when set in the aviation socket, the limiting protrusion 106 is also located inside the aviation socket; through the limiting protrusion 106, when it is placed in the aviation plug female socket, the limiting protrusion 106 can further prevent it from shifting in various directions inside, thereby ensuring the stability of the aviation plug female needle in the aviation socket.

[0033] In the embodiment of the present application, a plug 108 is provided at the connection position between the small column end 107 and the beveled groove 109, and in the first section of the female needle 101. The plug 108 located at the connection position between the small column end 107 and the beveled groove 109 can prevent the beveled groove 109 to the small column end 107 from being hollow when connecting the wire, causing the solder to flow into the hollow, resulting in loose welding or excessive consumption of solder during welding, causing waste.

[0034] In the embodiments of this application, refer to Figure 4As shown, a small hole 111 is also provided on the first section female needle 101, and the small hole 111 is located between the small column end 107 and the plug 108 in the first section female needle 101; the above-mentioned small hole 111 is located in the above-mentioned first section female needle 101 and between the two plugs 108, and corresponding protrusions are correspondingly provided on the above-mentioned aircraft carrier seat to make it cooperate with the above-mentioned small hole, and a screw hole can also be provided at the corresponding position of the aircraft carrier seat. When the screw is tightened, the stud enters the above-mentioned small hole 111, and the above-mentioned aircraft plug female needle is fastened with the screw.

[0035] In the embodiment of the present application, the petal structure 103 is configured to have six petals; through the six-petal petal structure 103, referring to Figure 4 and Figure 6 As shown, specifically, a six-petal contact structure with a stamped inner circle can be adopted. The six-petal contact point structure has good stability, optimizes and improves the product's plugging and unplugging performance, increases the contact area with the male needle 301 and effectively reduces impedance; the six-petal contact point structure has good stability, and the plug-in contact surface with the male needle 301 is large and the impedance is low.

[0036] In the embodiments of this application, refer to Figure 5 As shown, it also includes a bracket metal sheet 201, and the bracket metal sheet 201 is provided with a tip 202, and the tip 202 is connected to the end of the oblique slot 109. Through the bracket metal sheet 201, a plurality of aircraft plug pins can be arranged on it. On the one hand, the bracket metal sheet 201 can cooperate with the mold to make a mold for support, such as Figure 5 As shown, multiple (such as 4) can be grouped together as support frames when assembled to an aircraft carrier, further improving the efficiency of assembly.

[0037] In the embodiments of this application, refer to Figure 3 The end of the extension ring 105 is chamfered 112. Through the chamfer, when the male needle 301 is inserted into the female needle of the aircraft plug, the chamfer 112 structure can prevent the male needle 301 from being scratched by sharp corners during insertion. In addition, the chamfer 112 structure can also prevent the risk of being scratched when touched by human hands.
