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. What is a rectangular connector male plug?

  The rectangular connector male plug usually refers to the pin or plug-in terminal in the connector, which is used to form a connection with the female plug. In the connector of electronic equipment, the output end of the circuit is usually directly equipped with a plug, while the input end of the circuit is equipped with a socket, which forms the male and female plugs in the connection process. The plug generally refers to one end of the connecting wire or cable, which has several pins. The shape and number of the pins generally correspond to the number of holes in the corresponding socket so that they can be inserted into the correct position. In a rectangular connector, the correct connection of the male and female plugs is crucial, especially in high voltage, high frequency, high current and other environments. The correct connection can not only ensure the transmission quality of signals and electric energy, but also effectively avoid accidents such as short circuits, circuit breaks, and fires.

• 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.

• 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 a clean working environment to prevent dust and impurities from entering the connector.
