Miniature connectors play a vital role in modern electronic devices, especially in smartphones, wearables, medical devices and portable electronics. These connectors are favoured for their compact size and efficient use of space. Globally recognised micro connector brands such as TE Connectivity, Molex, Hirose, JST and Amphenol offer a wide range of micro connector solutions.

        TE Connectivity's Micro-D series connectors are known for their miniaturised design and high reliability and are widely used in military and aerospace applications. These connectors use a precision manufacturing process to achieve high density wiring in compact spaces.

       Molex's Micro-Fit 3.0 series connectors are recognised for their wide range of applications in automotive and consumer electronics. The design of these connectors focuses on miniaturisation and high current carrying capacity while maintaining excellent electrical performance.

       Hirose's µBNC (Micro BNC) series connectors are favoured by the market for their stability in high frequency signal transmission. These connectors incorporate differential signal transmission technology to reduce signal interference and improve signal integrity.

     JST's FH series connectors are known for their use in small medical devices. These connectors are designed with ergonomics and ease of use in mind while providing a high-density connectivity solution.

Amphenol's Micro-RF series connectors are recognised for their use in high-speed data communications. These connectors are designed with advanced signal transmission technologies to support data rates up to 10Gbps.

In miniature connector terminology, ‘contact resistance’ is a key indicator that affects the efficiency of current transfer. The ‘insertion and extraction force’ describes the amount of force required to insert or remove the connector, which is critical to ensuring the connector's mechanical stability.

      ‘Signal Integrity’ is a measure of a connector's performance when transmitting high-speed signals, including the amplitude, phase and frequency characteristics of the signal. Differential Signal Transmission’ is a method of transmitting signals using pairs of wires, which can significantly improve signal immunity.

     ‘Package size’ is an important parameter in the design of miniature connectors, which determines the amount of space occupied by the connector in the device. The ‘current carrying capacity’ describes the maximum current that the connector can safely transmit under normal operating conditions.

        Through these examples of well-known brands, we can see the high standards of micro connectors in terms of design, material selection, performance testing and environmental adaptability. The use of terminology, such as ‘contact resistance’, ‘insertion and extraction force’, ‘signal integrity’, ‘differential signal transfer ’, ‘package size’ and ‘current carrying capacity’, not only reflects the professionalism of the miniature connector industry, but also help equipment manufacturers and users to more accurately assess the performance and technical requirements of the connector.
