Card Edge Connectors - Edgeboard Connectors are specialized connectors used to connect expansion cards to the host board or backplane. This connector typically has a series of parallel metal contacts that are located on the edge of the expansion card, and when the expansion card is inserted into the host board or backplane, these contacts make contact with the corresponding connector contacts to form an electrical connection.

Card Edge Connectors - Edgeboard Connectors - have a wide range of applications in many fields. In the computer field, it is a key component of the expansion slots (such as PCI, PCIe slots) on the motherboard, which are used to connect expansion cards such as video cards, sound cards, network cards, and improve the performance and functions of the computer. In the field of communication, it is widely used in network equipment such as switches and routers to ensure high-speed data transmission and stable operation of equipment. In addition, in high-end fields such as industrial automation, medical equipment, aerospace, card edge linkers-edge plate connectors also play an important role, providing reliable support for the electrical connection of various precision equipment. These areas have extremely high performance requirements for connectors, requiring them to maintain stable electrical connections and signal transmission quality in harsh environments.

• 1. What are the types of card edge connectors?

  There are many types of card edge connectors, each suitable for different applications. Here are some common types in detail:
  
  1. PCI card edge connectors
  
  These connectors are used in computers to connect expansion cards (such as graphics cards or network cards) to the motherboard. They have multiple metal contacts to facilitate data and power transmission.
  2. SIM card edge connectors
  Used in mobile phones to secure and connect SIM cards. These connectors play a vital role in transmitting user identity and data within mobile networks.
  3. Mobile phone battery connectors
  Used to connect a mobile phone battery to its circuit board, ensuring a stable and reliable power interface with a firm edge.
  4. Printer connectors
  Connect a printhead or circuit board to a printer slot. They are equipped with multiple contacts to handle the exclusive transmission of print data and power signals.
  5. Monitor connectors
  Connect a monitor's circuit board to a video source such as a computer graphics card. Common types include VGA (Video Graphics Array), DVI (Digital Video Interface), HDMI (High Definition Multimedia Interface), and DisplayPort.
  6. Embedded system connectors
  Used in various embedded systems, such as industrial control equipment, automation equipment, medical instruments, etc., to connect internal circuit boards.

• 2. What is the purpose of a card edge connector?

  Card edge connectors play several key roles in electronic systems:
  Connectivity interface: They provide accessible interfaces for connecting PCBs to external components or systems, simplifying the establishment of electrical connections.
  Expandability: These connectors support modular expansion, allowing new modules or cards to be added to the system to enhance functionality or capacity.
  Signal transmission: They ensure the efficient transmission of various signals (digital, analog, and power) between the PCB and the connected device, which is critical for seamless system operation.
  Mechanical support: In addition to electrical connections, they provide physical support, holding the PCB in place and reducing the risk of disconnection or damage due to vibration or physical stress.

• 3. How to choose the right card edge connector?

  Choosing a suitable card edge connector requires considering the following aspects:
  Application requirements: Determine the connector type based on specific needs (such as data transmission or power connection).
  Contact quality: Choose a connector with high-quality contact to ensure reliable signal transmission and service life.
  Mechanical design: Choose a connector with a sturdy shell and alignment function to achieve a safe and stable connection.
  Compliance: Make sure the connector complies with relevant industry standards (such as RoHS) to ensure safe and environmentally friendly use.
