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 is a card edge connector?

  Card edge connectors, also called card edge connectors or card edge connectors, belong to the sub-category of board-to-board connectors. When the edge of the PCB (usually equipped with gold fingers) is inserted into the connector, these metal contacts form a reliable electrical connection, enabling communication and power flow between the PCB and the connection system. This type of connector provides a cost-effective, durable and rugged solution.
  
  Card edge connectors provide a way to quickly connect/disconnect single-sided, double-sided or multi-layer printed circuit boards, which requires card edge connectors to maintain good contact pressure in harsh environments and after multiple insertions and removals or shocks and vibrations, so that the PCB pads can be worn to a minimum.
  
  Card edge connectors are available in a variety of configurations and can be tailored for countless applications. You can find the card edge connector you need at Kangrui Connector.

• 2. 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.

• 3. How do edge connectors work?

  The operation of a card edge connector involves several simple but critical steps:
  Insertion: Insert the PCB into the connector slot, aligning the conductive traces on its edge with the contacts inside the connector.
  Contact: When fully inserted, the metal contacts of the connector touch the conductive traces of the PCB, establishing an electrical connection.
  Hold: The connector holds the PCB firmly in place, usually with the help of a locking mechanism or clip to ensure a stable connection.
  Signal transmission: Electrical signals or power are transmitted through these contacts, facilitating communication between the PCB and external devices.
  Disconnection: The PCB can be easily removed or replaced by simply unplugging it from the connector, without the need for complex tools.
