Rectangular Connectors - Board Spacers, Stackers (Board to Board)) are the key components of rectangular connectors. Plate gasket is a kind of thin sheet material placed between the contact surfaces of rectangular connectors, which is mainly used to strengthen the tightness and stability between connectors and protect the connector contact surface from damage. A stack connector (board-to-board) is a form of rectangular connector specifically designed to connect two or more circuit boards, usually with a multi-layer structure that allows boards to be stacked vertically and electrically connected through the connector. Board-to-board connectors transmit signals and power from one board to another via pins or terminals inside them, enabling tight integration and efficient communication between boards.

Rectangular Connectors - Board Spacers, Stackers (Board to Board)) are widely used in many fields such as communications, computers, automotive electronics, consumer electronics and industrial automation. In the communications industry, they are used for interboard connections for high-speed backplane connectors, switches, routers and other devices. In the computer field, it is commonly used in the internal board connection of servers, workstations, laptops and other devices to improve the overall system performance. In automotive electronics, it is used to establish a reliable electrical connection between the ECU, sensors and actuators to ensure the smooth operation of the vehicle control system.

• 1. What are the types of board-to-board connectors?

  1. Pin headers/pin headers: This is the cheapest and most common connection method, suitable for low-end, large-sized smart devices, development boards, debugging boards, etc. Its advantages are cheap, convenient, stable hard connection, strong overcurrent capacity, and convenient welding and testing. The disadvantages are large size, difficult to bend, large spacing, and it is difficult to connect hundreds of pins.
  2. High-end board-to-board plug-in: This connector is denser than pin headers and is widely used in compact products. Its advantages are a large number of pins, small size, and the ability to achieve more functions within a limited size. The disadvantages are high prices, cannot be plugged and unplugged frequently, and the structural design needs to be fixed.
  3. Thickened board-to-board connector: This connector is suitable for development boards, test boards, and large and fixed devices, such as computer case wiring. Its advantages are cheap and common, and it is very easy to connect and measure when used with pin headers. The disadvantages are large size, difficult to fix, and not suitable for mass production scenarios.
  4. FPC connector: This connector is suitable for smart hardware devices that need to take signals out of the motherboard. Its advantages are flexibility, small size, and changeable shape. It is suitable for connecting the main board with the daughter board, connecting the main board with the peripherals, and wiring that needs to be bent.

• 2. Rectangular connector standards

  ‌1. Rated voltage and rated current‌: The rated voltage and rated current of rectangular connectors are important indicators to measure their performance.
  For example, the GB/T 42207.5-2022 standard stipulates that the rated voltage of rectangular connectors is DC 250V and the rated current is 30A, while another standard stipulates a rectangular connector with a rated voltage of DC 400V and a rated current of 16A.
  
  ‌2. Design and structure of connectors‌: The design of rectangular connectors includes its jack design, termination form, fixing method, etc.
  For example, the CY23, CRM, and J36 series rectangular electrical connectors use termination forms such as hyperbolic wire spring jacks and printed circuit board soldering, and provide a variety of fixing forms, such as threaded guide pins and guide sleeves with locking functions, as well as riveting, threaded fastening and other fixing forms.
  
  ‌3. Materials and manufacturing standards‌: The manufacturing materials and standards of rectangular connectors are also important guarantees of their performance.
  For example, the insulator of the connector can be made of LCP material or PA66 material, which has good temperature range and stability and is suitable for different application environments. The material selection of the connector shell depends on the specific needs of the application, such as plastic, metal, alloy or glass fiber reinforced plastic, which has good insulation performance, wear resistance, corrosion resistance and mechanical strength.

• 3. Precautions for installing rectangular connectors

  Make sure all screws are tightened to prevent the connector from loosening.
  When wiring, pay attention to the positive and negative poles of the wires to avoid connecting them incorrectly.
  During the assembly process, avoid damaging the mating surface of the connector to avoid affecting the electrical performance.
  Ensure the working environment is clean to prevent dust and impurities from entering the connector.
