Description

Technical Field

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

[0002] As avionics equipment evolves towards higher density and modularity, connectors, as key components for signal and power transmission between various electronic systems, have become crucial factors affecting overall performance and safety due to their structural stability, electrical connection reliability, and mating accuracy. Existing aviation connectors typically employ a method of individually inserting conductive terminals into the base or housing. Because the terminals and base are not integrated, they are prone to loosening or poor contact during vibration, impact, or long-term use, thus affecting signal transmission stability and system reliability.

[0003] Furthermore, existing connectors often lack effective foolproof designs and guiding mechanisms in their mating structures, making it easy for users to make mistakes such as inserting them backwards or incorrectly during actual operation. This can even lead to deformation or damage of the terminals due to stress, increasing maintenance costs and the risk of system failure. There is a need to provide an aviation connector that solves these problems. Utility Model Content

[0004] The purpose of this application is to provide a technical solution to address the problems mentioned in the background section.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] An aviation connector includes a base and a plurality of conductive male terminals. Each of the conductive male terminals is molded with an insulating block and mounted on the base therethrough. Anti-foolproof positioning pins are also provided on both sides of the base. At least one insertion guide post is also installed on the base between the anti-foolproof positioning pins.

[0007] Preferably, the base at the anti-foolproof positioning pin is further provided with a fixing piece, and one end of the fixing piece is provided with a screw hole and is bent into shape.

[0008] Preferably, one end of the conductive male terminal is sheet-shaped, and the other end is cylindrical.

[0009] Preferably, the width of one section of the conductive male terminal sheet is 1.5mm-5mm and the thickness is 0.3mm-1mm.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] This connector solution includes a base and several conductive male terminals. Each conductive male terminal is integrally fixed to an insulating block via injection molding, ensuring excellent structural stability and electrical insulation when installed on the base, preventing loosening or displacement due to vibration or long-term use. The insulating block serves as the mounting medium, firmly embedding the conductive male terminals into the base, ensuring precise positioning and long-term reliability of the conductive components. To prevent incorrect insertion direction by the user, anti-foolproof positioning pins are provided on both sides of the base. By cooperating with the corresponding structure of the female end, they achieve mechanically limited insertion in one direction, effectively eliminating reverse insertion and improving system safety. Simultaneously, at least one insertion guide post is provided on the base between two anti-foolproof positioning pins.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-3 An aviation connector includes a base 1 and a plurality of conductive male terminals 2. Insulating blocks 3 are molded onto each of the conductive male terminals 2 and mounted on the base 1 via them. Anti-foolproof positioning pins 4 are respectively provided on both sides of the base. At least one insertion guide post 5 is also installed on the base 1 between the anti-foolproof positioning pins 4. In this connector design, each conductive male terminal 2 is integrally fixed to the insulating block 3 by injection molding, thereby ensuring good structural stability and electrical insulation performance when the terminal is installed on the base 1, preventing loosening or displacement due to vibration or long-term use. The insulating block 3 serves as the mounting medium, firmly embedding the conductive male terminals onto the base 1, ensuring precise positioning and long-term reliability of the conductive components. To prevent users from inserting the plug in the wrong direction, anti-foolproof positioning pins 4 are provided on both sides of the base 1. By cooperating with the corresponding structure of the female end, they can achieve mechanical limiting of insertion in one direction, which can effectively prevent the problem of reverse insertion or incorrect insertion and improve system safety. At the same time, at least one insertion guide post 5 is provided on the base 1 between the two anti-foolproof positioning pins 4. During the insertion process, the guide post cooperates with the guide hole of the female end to guide the plug to be inserted along the correct path, effectively preventing the problem of insertion misalignment and terminal damage, reducing insertion and extraction resistance, and improving the smoothness of operation.

[0024] Preferably, the base at each of the anti-foolproof positioning pins 4 is further provided with a fixing piece 6, one end of which has a screw hole 61 and is bent into shape. The fixing piece 6 is integrally connected to the base 1 through a bent structure design, and a screw hole 61 is pre-set at one end, so that the entire connector structure can be firmly fixed to the equipment mounting surface by screws, improving seismic performance and structural stability. The bent design not only facilitates cooperation with external structures, but also relieves installation stress, adapts to different installation angles or space constraints, and improves the versatility and reliability of the connector.

[0025] Preferably, the conductive male terminal 2 has one sheet-like segment 21 and the other cylindrical segment 22. This structure achieves a dual-form terminal design. The sheet-like segment 21 is used to connect with planar structures such as circuit boards or ribbon cables, providing a larger contact surface and welding area, thus improving conductivity and mechanical stability. The cylindrical segment 22 is used to connect with the female terminal socket, ensuring smooth insertion and removal and compatibility with various interface types. The combined application of these two forms improves the connector's adaptability and electrical performance.

[0026] Preferably, the width of one section of the conductive male terminal 2, the sheet-like portion 21, is 1.5mm-5mm, and the thickness is 0.3mm-1mm. This dimensional design is based on the stringent requirements for balancing the structural rigidity and conductivity of aerospace connectors in complex environments. The sheet-like terminal mainly connects to planar structures such as PCB pads and power cables. Its width determines the size of the soldering or pressing surface, thus affecting the soldering strength and heat dissipation capacity; the thickness directly affects the cross-sectional area, which in turn affects the resistivity, current carrying capacity, and bending resistance. In the aerospace field, connectors need to withstand frequent mating and unmating, high-frequency vibration, and temperature cycle changes. Therefore, the size range of the terminal must ensure sufficient thermal stability, electrical continuity, and structural rigidity without sacrificing installation density.

[0027] Preferably, the diameter of one segment of the cylindrical 22 of the conductive male terminal 2 is 0.8mm-3.5mm. Controlling the terminal diameter between 0.8mm and 3.5mm can effectively cover the connection requirements from low-power high-density connection to medium-to-high-power low-frequency plugging and unplugging, while taking into account the material response range of mechanical wear distribution and thermal stress diffusion during plugging and unplugging cycles.

[0028] Preferably, one section of the cylindrical part 22 of the conductive male terminal 2 has a diameter of 1 mm. A diameter of 1 mm results in a cross-sectional deformation response that is less than the critical elastic compression zone, enabling uniform surface or point contact distribution under small insertion force. This is suitable for plug-in systems sensitive to structural loads. This size allows the terminal to recover from deformation within the elastic range, thereby maintaining interface integrity and contact stability after multiple insertions and removals.

[0029] Preferably, one section of the cylindrical portion 22 of the conductive male terminal 2 has a diameter of 2mm. This 2mm diameter is located at the critical point of rigidity and flexibility in a typical aerospace connector structure, achieving an optimal balance between insertion force, contact area, conductive path, and interface temperature rise. The rigidity at this size is sufficient to support repetitive elastic deformation under high insertion and extraction frequencies, avoiding contact resistance fluctuations caused by fretting wear. Simultaneously, the localized thermal diffusion region generated at the contact surface can be stabilized in a low-gradient change state, helping to maintain a constant terminal interface resistance. Furthermore, this diameter facilitates conventional precision machining and electroplating, resulting in high material utilization and consistent finished product quality.

[0030] Preferably, one section of the cylindrical portion 22 of the conductive male terminal 2 has a diameter of 3 mm. The larger contact cross-section formed by the 3 mm diameter has a lower current density and heat power density, which can slow down the local heating rate and significantly reduce thermoelectric fatigue. The structural stiffness is significantly improved, giving it stronger resistance to lateral shear force and axial indentation force during the insertion process, and it can still maintain interface alignment even when the insertion frequency is high or there are slight errors in the insertion and removal guidance accuracy.

[0031] Preferably, the insertion guide posts 5 are arranged in two spaced intervals. The double guide posts can form a stable spatial insertion reference frame, and their geometric arrangement constitutes two constraint points in space. The planar stability and axial alignment of the connector are achieved through the minimum three-point positioning rule. The two guide posts can restrict the rotational degree of freedom of the connector on the insertion and extraction path (constraining the torsional angle) and effectively disperse the reaction torque brought by the insertion force, thereby avoiding the transverse shear stress generated by the connector due to initial insertion deviation or dense terminal arrangement. In addition, the guide structure provides interference pre-positioning in the initial stage of insertion, ensuring that the male terminal and female hole contact surface achieve synchronous cooperation under controlled load, improving insertion accuracy and contact surface wear symmetry.

[0032] Preferably, the insertion guide post is provided as two spaced-apart posts. Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
