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 the role of the male plug of the rectangular connector?

  The male plug of the rectangular connector is mainly used to transmit signals and energy, and is an indispensable part of electrical equipment. The design and application of the rectangular connector are based on its unique structure and function, making it widely used in industrial control systems, instrumentation, communication equipment, and aerospace. The principle of the rectangular connector is to use the metal contact between the plug and the socket to achieve electrical connection. There are neatly arranged metal terminals in the socket, and there are a corresponding number of pins on the plug corresponding to them. When the socket and the plug are properly docked, the pins can be connected to the terminals to form a path, thereby realizing the transmission of electrical signals and power. The rectangular connector also has the characteristics of waterproof, dustproof, shockproof, and fireproof, which can adapt to various harsh environments and ensure the stable operation of the equipment. Due to its high reliability and durability, rectangular connectors are also widely used in automobiles, rail transit, medical equipment and other fields, becoming an ideal choice for connecting electrical equipment.

• 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. How to install rectangular connectors

  Assembly steps of rectangular connectors
  
  1. Preparation: Prepare rectangular connectors, screwdrivers, screws, electric drills, mounting plates, and rulers.
  2. Determine the position: Measure the position of the rectangular connector on the mounting plate with a ruler and mark this position.
  3. Drill holes: Use an electric drill to drill holes on the mounting plate that match the rectangular connector.
  4. Fix the connector: Place the rectangular connector into the drilled hole and fix it with screws.
  5. Connect the wires: Insert the wires into the gap of the rectangular connector, make sure the wires are inserted in place, and then fix the screws with a screwdriver to ensure that the wires are firmly connected.
  ‌6. Complete the connection‌: Insert the wire at the other end into another rectangular connector and lock it.
