In this article, we will give you an in-depth explanation of how we should choose aviation plugs when purchasing, as well as its application scenarios and the advantages of aviation plugs compared with other domestic products. Let's take a look together below.

　　There are different classification methods for aviation plugs. According to the frequency, there are high-frequency aviation plugs and low-frequency aviation plugs; according to the appearance, there are circular connectors, according to the purpose: aviation plugs for cabinets, aviation plugs for audio equipment, power aviation plugs, special-purpose aviation plugs and so on.

　　The importance of aviation plugs in electronic systems is often underestimated. Many designers of electronic systems have had a similar experience: use the cheapest aviation plugs, but they often end up paying a higher cost. Incorrect selection and use of aviation plugs can cause system failures, product recalls, product liability cases, circuit board damage, rework and repairs, which in turn can lead to loss of sales and customers. Therefore, when designing electronic products, please do not underestimate the importance of aviation plugs, otherwise you will only make mistakes and make up for it. Obviously, the importance of choosing a suitable aviation plug for electronic devices.


　　So, how to choose an aviation plug? Affected by the economic crisis, cost factors will be taken into consideration when designing, but in addition, more attention should be paid to the high quality and stability of the product, as well as the design of the aviation plug itself. Features. I think I can provide some reference opinions for electronic designers through the innovative design of ERNI aviation plugs in the following aspects:

　　First: the idea of double pole design. In the ERNI aviation plug series, the double-pole design idea is consistent throughout. Vividly speaking, the double-bar design can be described as "two birds with one stone". Optimized terminal design to adapt to high-speed signal transmission, providing a higher orientation tolerance. In terms of inductance, capacitance, impedance, etc., the double-bar terminal structure is smaller than the box-type terminal structure for high-speed applications, and optimized to achieve the smallest discontinuity. The double-pole design allows multiple aviation plugs to be on one circuit board without plugging or short circuit problems, and there is no need for a large number of signals on a single aviation plug. The simple routing of the double poles can save space, make the aviation plug smaller, and simplify the detection of welding pins. For example, put 12 on a board. It also reduces rework costs. Practical applications such as telecommunications terminal user equipment, etc.

　　Second: No bent pin design in the assembly process. Traditional stamping may cause bending or deformation of pins due to improper processing, and the bending process will cause capillary cracks, which is not desirable in terms of long-term product performance, and will also affect circuit performance and cost. ERNI uses direct stamping of the corners, stamping terminals can avoid capillary cracks caused by the bending process, and ensure a complete electromechanical connection. The pin coplanarity is 100%, and the tolerance is controlled to ±0.05mm. The 100% surface mount pin coplanarity test ensures the reliability of the circuit board assembly process, ensures good soldering, improves the product quality rate, and reduces the cost. And improve the firmness of the right-angle aviation plug to prevent the aviation plug from being damaged due to improper operation. The term "unbreakable" is very appropriate. Especially suitable for inkjet printer controller, InterfaceModule module interface, etc.


　　Third: Surface mount design with high retention force. For SMT products, it is generally believed that the holding power on the board is poor. Is the PCB retention force of surface mount terminations lower than that of through-hole terminations? The answer is: not necessarily. Through design improvement, the retention of PCB can be effectively improved. If the soldering bracket, the hole (microhole) of the surface mount pin, and the large soldering pad are superimposed, the holding force can be improved. In fact, even I/O aviation plugs can also use surface mount pins. This can be vividly compared to "take roots". For example, in the design of X-ray machines, ultrasonic scanners, and robotic Ethernet switches.

　　Fourth: Robust design. To determine the reliability of the aviation plug, while allowing the use of flat crimping tools, the pole plate is fixed on the shell to improve the robustness, to achieve a more superior manufacturing process and increase output. To sum it up in one word is "solid as a rock." Specific applications such as positron emission tomography scanners, railway car embedded systems, etc.

　　Fifth: High current, small spacing design. With the miniaturization of automotive electronics and consumer electronics, the design concept of high current and small spacing needs to be considered. Sixth: Advanced lock design. ERNI uses a double lock design to meet different needs. The positive lock is designed for strong vibration applications. It is very suitable for automotive and subway applications. The friction lock is designed for general vibration applications. Double locks and double safety insurance ensure a reliable connection, and no special tools are required for on-site disassembly (repair/replacement) of cables. It is suitable for the design of monitors, LED car lights, etc.

　　Terminals used in aviation plugs are an important component of electromechanical components for connecting electrical circuits. Their specifications and quality requirements are very strict. Therefore, the power handling capability of the device should be considered first when selecting. Different countries have different standards when determining the power and performance specifications of the terminal products, and there is no same standard. Therefore, engineers must know how the product performance data is tested and determined, rather than simply obtaining it from the data manual.

　　In Europe, the current rating of the IEC standard marked device is determined by detecting the temperature of the metal conductor when the current increases. When the temperature of the metal pin is 45°C higher than the ambient temperature, the measurement staff will use the current as the rated current Or the maximum current value, 80% of the maximum current is also designated as the allowable current value; the UL standard adopted in the United States is different from the current value defined by the European IEC standard. The UL standard will make the temperature of the metal conductor 30°C higher than the ambient temperature 90% of the current value at the time is the nominal current value of the device. Although the standards are different, it can be seen that the temperature of the metal conductor sector is still very important in the application, and the industrial equipment usually needs to work in a high temperature environment of 80 ℃. If it is 30 ℃ or 45 ℃ higher than the environment, then the wiring The temperature of the terminal will exceed 100°C. Some materials such as compact package device materials may not meet the heat dissipation requirements. Therefore, the current must be much lower than the rated value when the terminal is used.

　　More and more companies are beginning to use terminal blocks produced in different countries. To avoid causing too many problems for product designers, they should first understand the differences between the different standards adopted by different countries. For example, Europe uses nominal value measurement. Method, in the European device design, it should be lower than the nominal value.


　　Secondly, pay attention to the termination technology when choosing the aviation plug terminal. Many termination technologies use through-hole connection. This type of connection requires mechanical support to ensure the power layer embedded in the multilayer circuit board. Maintain solid electrical contact. In addition to paying attention to the connection method, also pay attention to the type of pins connecting the terminal to the circuit board. Usually single-pin models are selected, but there are also multi-pins. The use of multiple pins can make the current more evenly distributed to the circuit board. In the wiring, it can provide more reliable mechanical stability and improve the firmness of welding.

　　The final consideration when choosing aviation plug terminals is appearance. A good appearance can have a good affinity for users.
