1. Current-carrying capacity When selecting connectors, it is important to focus on their current-carrying capacity. To ensure the reliability and stability of the connectors, we should apply derating design and also consider the insulation voltage between the pins.   2. Structural dimensions The external dimensions of the connectors are crucial for product connections, especially in situations with limited space, such as connectors on single boards. We must avoid interference with other components. Depending on the available space and installation position, choose appropriate installation methods (front or rear installation) and connector shapes (straight, angled, T-shaped, circular, square). 3. Impedance matching Impedance matching is particularly critical for certain signals, especially RF signals. Strict adherence to impedance matching is necessary, as mismatching can cause signal reflections and affect signal transmission. Generally, signal transmission requirements for connector impedance are relatively lenient.   4. Shielding With the advancement of communication products, electromagnetic compatibility (EMC) is becoming increasingly important. Therefore, when selecting connectors, it is essential to ensure they have metal housings and are equipped with cable shielding layers. The shielding layers must be connected to the connector's metal housing to achieve effective shielding. An alternative method is to use injection molding to wrap the plug area with copper foil and weld the cable's shielding layer to the copper foil. 5. Misconnection prevention Preventing misconnections involves two aspects. Firstly, the connectors themselves should have misconnection prevention features since they can be erroneously connected due to rotation or misalignment. It's preferable to choose connectors with misconnection prevention features or arrange their positions to facilitate unique assembly. Secondly, when multiple signals use the same type of connector to reduce the number of materials, it is crucial to be mindful of the risk of inserting plug A into socket B. To avoid potential serious consequences (not just simple warnings), different types of sockets, such as male and female connectors, must be chosen.   6. Reliability Connectors primarily serve the purpose of signal transmission, so the connection points must be reliable. For instance, surface contact reliability is superior to point contact, and pinhole-type connectors are better than leaf spring-type connectors.   7. Versatility In the process of connector selection, it is preferable to choose materials that are as versatile as possible, especially among products within the same series. This reduces the variety of materials, increases purchase quantities, thus lowering costs and reducing supply risks.   8. Operating environment Connectors used in different environments have specific requirements, such as outdoor, indoor, high-temperature, high-humidity, salt spray, fungus, and cold conditions, each having unique connector demands.   9. Insertion and withdrawal frequency The number of times connectors can be inserted and withdrawn is limited, and when this limit is reached, the performance of the connector may decline. Connectors intended for frequent insertions and withdrawals should be selected with careful attention to their durability. 10. Live conditions Connector types should be chosen based on whether they will be used in live conditions or not. Pin-type and socket-type connectors may be more suitable for different live conditions.   11. Comprehensive consideration In the process of connector selection, different factors often interact with each other. Hence, during the selection process, it is essential to take a comprehensive approach and choose the most suitable connectors. The quality of connector selection will have varying degrees of impact on the product at different stages.

Whether it is a high-frequency electrical connector or a low-frequency electrical connector, insulation resistance, dielectric withstand voltage (also known as dielectric strength) and contact resistance are the most basic electrical parameters to ensure that the electrical connector can work normally and reliably. Usually, there are clear technical index requirements and test methods in the routine delivery inspection items of groups A and B of the quality consistency inspection of the technical conditions of electrical connector products. These three inspection items are also an important basis for users to judge the quality and reliability of electrical connectors. However, according to the author's practice in the inspection of electrical connectors for many years, it has been found that there are many inconsistencies and differences in the specific implementation of relevant technical conditions among various manufacturers and between manufacturers and users. , operating methods, sample handling and environmental conditions and other factors are different, which directly affect the accuracy and consistency of the test. For this reason, it is very beneficial to improve the reliability of electrical connector inspection to conduct some special discussions on the three conventional electrical performance inspection items and the problems existing in actual operation.        In addition, with the rapid development of electronic information technology, a new generation of multi-functional automatic testers are gradually replacing the original single-parameter testers. The application of these new test instruments will greatly improve the detection speed, efficiency, accuracy and reliability of electrical properties.   Insulation resistance refers to the resistance value that occurs when a voltage is applied to the insulating part of the connector to cause leakage current on the surface or inside of the insulating part. That is, insulation resistance (MΩ) = voltage (V)/leakage current (μA) applied to the insulator. Through the insulation resistance test, it is determined whether the insulation performance of the connector meets the requirements of the circuit design, or whether its insulation resistance meets the relevant technical conditions when it is subjected to environmental stress such as high temperature and humidity.      Insulation resistance is the limiting factor in designing high impedance circuits. Low insulation resistance means large leakage current, which will destroy the circuit and normal operation. If a feedback loop is formed, the heat and DC electrolysis generated by excessive leakage current will damage the insulation or deteriorate the electrical performance of the connector.        DMIC produces and sells various high-current connectors, connectors, UPS/EPS power sockets and other products, specializing in providing supporting equipment for manufacturers of automobiles, electric vehicles, communication power supplies, medical equipment, power distribution equipment, handling equipment, solar energy and new energy product service.

As an essential electrical device, connectors are primarily used for connection and conduction. Among various materials, metals have the most outstanding conductivity, making their usage irreplaceable. However, metals also possess their own "personality," referred to as resistance in physics, which is a crucial factor in the electrical performance of connectors.   There are many types of power connector battery plugs, which exist in different corners of our surrounding environment. We may use connectors unconsciously in our daily life. So, what exactly is a connector? To understand better, let's consider items in our homes. For example, a plug for a desk lamp, an interface for a USB flash drive, or a jack for headphones are all examples of small quick-connect connectors. Larger connectors, on the other hand, may be familiar to you, as they can be found in control gear or fiber optic connectors in your car. There are many classifications of resistance, but today we mainly focus on analyzing the electrical strength of the battery plug connector of fast power supply products. Signal transmission needs to be loaded with electric waves, using the power transmission ability in the conductor. However, if there is interference or operational problems in the transmission of electricity, like a ship navigating a river, signal errors and loss can occur. This situation must be resolved.   To account for interference, the current needs to remain within the transmission line without being affected by other signals. Solutions to this situation include incorporating EMI shielding on the mating portion of the connector. During the test, a certain range of frequencies is loaded into the connector, and the attenuation of the transmission frequency after passing through the connector is checked to determine whether the connector meets the required standards. Regarding the issue of transmission delay, it is mainly attributed to internal factors of the metal. Different metals possess varying resistance values and require different cross-sectional sizes. Consequently, the design and material selection for a specific connector demand careful consideration.

The use of wiring terminals is highly prevalent in various applications today, making their quality and production standards critically important. They serve as fundamental assurance factors for production efficiency and processes. Given their widespread demand and strong functionality, there is a wide variety of product types available, particularly in terms of the compatibility between different plugs and sockets. DMIC supports OEM development, design and overall wire harness solutions.Achieving universality in these connections would better align with practical production needs.   To meet these requirements, it is common practice to incorporate locking mechanisms at the connecting positions. This facilitates easy insertion and removal of terminals while ensuring secure fastening. Consequently, the terminals can function more reliably, leading to their popularity in the market. The most popular types of terminals in the market are socket connectors that adapt to various types of plugs. The greater the adaptability, the more satisfied the purchasers become. This concept is reminiscent of the interchangeable standard components used in early industrial production. The ability to interchange components without affecting performance is a result of the similar internal structure of connectors, with slight variations in design and tighter integration with the female counterparts. If standardized production is achieved, wiring terminals will possess the same level of adaptability.
