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. The difference between male and female connector pins

  1. What are male and female connector pins?
  
  Male and female connector pins are the two most commonly used terminals in connectors and are also important components of connecting circuits. Male and female pins are usually made of metal, and their shapes and sizes can vary depending on the connector. Male and female pins usually appear in pairs, and the male pin can be inserted into the female pin for connection.
  
  2. The difference between male and female pins
  
  The difference between male and female pins is usually in their shape and use. The male pin is the plug in the connector, usually with a cylindrical or rectangular head, with a needle-like metal on the top, which can be inserted into the female pin for connection. The female pin is the socket in the connector, usually one or more jacks, into which the male pin can be inserted for connection. Therefore, male and female pins often appear in pairs.
  
  3. Use of male and female pins
  
  Male and female pins can be used to connect various electrical devices and lines, such as televisions, computers, telephones, and cars. They are very convenient to use and can be inserted and unplugged for easy replacement.
  
  Different connectors may require different types of male and female pins. Some connectors may require a pair of male/female pins, while others require multiple male/female pins for connection

• 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. 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.
