Backplane Connectors - Specialized refers to backplane connectors designed and produced to meet the needs of specific industries or applications. These connectors are carefully optimized in terms of structure, materials, electrical properties, etc., to ensure the best performance in a specific working environment. They not only inherit the basic functions of traditional backplane connectors, such as connecting circuit boards, transmitting signals and currents, but also put forward higher customization requirements for specific application scenarios, such as high temperature resistance, corrosion resistance, electromagnetic interference resistance, etc.

Backplane Connectors - Specialized applications are broad and diverse, mainly covering industries with high requirements for electrical connection performance. First of all, in the aerospace field, backplane connectors - dedicated are widely used in the electrical systems of aircraft, satellites and other equipment to ensure the reliability and stability of electrical connections in harsh environments such as extreme temperatures, high vibration and strong electromagnetic radiation. Secondly, in the field of military defense, such connectors also play an important role in providing stable and reliable electrical connections for weapons and equipment and command and control systems. In addition, backplane connector - dedicated is also widely used in industrial automation, medical equipment, high-speed railway, Marine engineering and other fields.

• 1. What is a backplane connector?

  A backplane connector is a connector used in large communication equipment, ultra-high performance servers, giant computers, industrial computers, high-end storage devices, etc. Its main function is to connect a single board (daughter card) and a backplane, so that the single board and the backplane form a 90-degree vertical structure, thereby transmitting high-speed differential signals or single-ended signals and large currents

• 2. How does a backplane connector work?

  The working principle of a backplane connector is mainly to connect a single board (daughter card) and a backplane to achieve high-speed differential signals (differentencial signals) or single-ended signals (single end signals) and large currents. ‌
  The backplane connector is a special connector designed to establish an electrical connection between a single board and a backplane. The design of this connector forms a 90-degree vertical structure between the single board and the backplane, thereby optimizing the efficiency and stability of signal transmission. The main application areas of backplane connectors include large communication equipment, ultra-high performance servers, giant computers, industrial computers, and high-end storage devices. In these applications, backplane connectors play a vital role, ensuring the reliability of high-speed signal transmission and the stable flow of large currents.
  
  The design of the backplane connector also takes special consideration of the shielding system to reduce the interference and crosstalk problems that may occur in high-frequency signal transmission. The shielding system includes at least one shielding unit, each of which is composed of at least one U-shaped shielding sheet, a sealing shielding sheet and a grounding metal connecting sheet. Such a design not only improves the quality of signal transmission, but also enhances the durability and reliability of the connector.
  

• 3. How to use the backplane connector?

  The main function of the backplane connector is to connect the single board (daughtercard) and the backplane to form a 90-degree vertical structure, which is used to transmit high-speed differential signals or single-ended signals and transmit large currents. ‌This connector usually consists of a metal slot and several circuit chips. By inserting the external device into the slot, the communication function between the external device and the computer motherboard is realized. The backplane connector is generally located on the back of the computer case, hence the name. Its main purpose is to connect the motherboard and various peripheral devices, thereby expanding the input and output functions of the computer, such as connecting a printer, mouse, keyboard, monitor, etc. At the same time, it is also an indispensable component for upgrading computer hardware. Users can add new expansion functions or replace damaged original ports by replacing the backplane connector.
  
  The production process and quality management of the backplane connector have strict requirements because of the diversification and refinement of its internal structure. In order to meet the interface requirements of various different devices, the backplane connector needs to have various complex arrangements, pin numbers and shapes, etc. At the same time, on the basis of ensuring the quality and stability of signal transmission, it is also necessary to consider the compatibility of metal slots with external devices and mechanical strength.
