Rectangular Connectors - Headers, Male Pins are key components that enable signal or power connections between circuits. It consists of an insulated base and multiple metal pins arranged in a rectangular array, which are fixed to the base by crimping, welding, or threading. The needle holder serves as the female end, while the male pin serves as the corresponding male end, and the two are electrically connected through precise coordination. In terms of design principles, rectangular connectors emphasize the characteristics of high density, high reliability, and easy insertion and removal, and are widely used in situations that require stable and efficient signal transmission. Its characteristics include low contact resistance, high withstand voltage, wear resistance, and resistance to electromagnetic interference.

Rectangular Connectors - Headers, Male Pins are widely used in various electronic devices, especially in computer hardware, communication equipment, industrial automation control and other fields. In the field of computer hardware, they are used to connect core components such as motherboards, graphics cards, and memory modules, ensuring high-speed data transmission and stable system operation. In communication equipment, rectangular connectors are used to connect circuit boards, modules, antennas, etc., supporting high-speed signal transmission and complex circuit layouts. In industrial automation control systems, rectangular connectors serve as a bridge between sensors, actuators, and controllers to achieve precise control and data feedback.

• 1. 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.

• 2. What are the types of rectangular connectors?

  ‌Pin-type rectangular connector: This is the most common type of rectangular connector. The metal pin is inserted into the interface hole and rotated to tighten to achieve conductive connection.
  ‌Snap-on rectangular connector: It is fixed with self-locking mechanisms such as spring sheets or clips and is suitable for use in vibration environments.
  ‌Patch-type rectangular connector (SMT type): Suitable for use in surface mount technology (SMT), convenient and fast.
  ‌Board-to-board rectangular connector: Mainly used for the interconnection of board-level and system-level circuits, with high-density connection, low plug-in and pull-out times, and easy maintenance.
  ‌Wire-to-board rectangular connector‌: Suitable for connecting internal signals and power of equipment, can withstand high current and high temperature environments, and has the advantages of easy installation and convenient maintenance.
