D-Sub connectors are a type of electrical connector that is commonly used in various applications where a secure and reliable connection between two or more terminals is needed. Among the different types of D-Sub connectors, DBMM21W1PP is a twinaxial connector specifically designed for mobile communication applications. DBMM21W1PP connectors are small connectors that are composed of four components, namely: a plastic housing, a dielectric insert, two contacts and two solder contacts. The insert is made of high-grade epoxy material and has two channels that provide support for the two contacts which are actually the electrical terminals. The contacts are constructed from high-grade brass and are plated with gold to ensure maximum conductivity. The solder contacts are also made of high-grade copper and are soldered onto the board.The DBMM21W1PP connectors are widely used in various types of mobile communication applications such as CDMA, GSM, and UMTS network architectures. The main purpose of these connectors is to provide secure and reliable connections between two or more terminals. They are also used in wireless and Ethernet networks as well as in high-speed serial data transmission.The DBMM21W1PP connectors have a surround fabric shield and are resistant to extreme temperatures ranging from -40 degree Celsius to + 85 degrees Celsius. This makes them ideal for applications that need a high level of heat resistance and durability. Additionally, they also feature a superior electrical and environmental performance due to their superior heat dissipation capabilities, corrosion resistance and superior shielding.The DBMM21W1PP connectors are also capable of transferring different frequencies on the same connection. This makes them ideal for applications that require simultaneous communication between a mobile terminal and the base station. The connectors are also highly reliable in terms of durability and signal integrity.The working principle of the DBMM21W1PP connectors is based on the concept of compression connection. When the connector is inserted, the internal contacts are compressed down by the contact force. This compresses the contacts down and ensures a solid and reliable connection. All the contacts are then held together by the dielectric insulator, which isolates them from the external environmental factors. The insertion of a DBMM21W1PP connector must always be done with a proper tool that is designed specifically for this purpose. This is to ensure that the connectors are inserted correctly and that the contacts are not damaged or misaligned during the process.Overall, the DBMM21W1PP connectors are a reliable and versatile electrical connector that can be used in a variety of different applications in mobile communication networks. Their superior heat resistance, durability and reliable data transmissions make them one of the most popular connectors for mobile applications.
