Circular Connectors - Housings are an important part of circular connectors that provide physical support and protection for connectors. This housing is usually made of metal or high-strength plastic, which ensures the stable operation of the connector in complex and changeable environments. The design of the circular connector housing takes into account mechanical strength, electromagnetic shielding, protection level and other factors to meet the needs of different applications.

Circular Connectors-Housings In the field of industrial automation, circular connector housings have become an indispensable part of connecting various automation equipment and control systems because of their durability and easy maintenance. In the aerospace industry, in the face of extreme environmental conditions and demanding performance requirements, the circular connector housing ensures the reliable operation of the connector in extreme conditions such as high altitude, high speed, high temperature and low temperature by using high-strength materials, special surface treatment and precision sealing design. In addition, in many industries such as automotive electronics, medical equipment, communication equipment, energy and power, the circular connector shell also plays a key role, providing a solid guarantee for the stable connection and efficient operation of electrical and electronic equipment.

• 1. Circular connector structure?

  1. Shell: Usually made of materials such as metal or plastic, it serves as the shell of the entire connector and is used to protect the internal electronic components. The shape of the shell is usually circular or cylindrical.
  2. Plug: A part of the connector, usually fixed at one end of the device, and its structure includes the center lead, shell, contact, etc.
  3. Socket: The other part of the connector, usually fixed at the other end of the device. The socket usually corresponds to the structure of the plug and is composed of pins, contacts, etc.
  4. The key part of the connector, used to transmit signals and energy between the plug and the socket. The contact is usually made of conductive metals such as copper, which has high conductivity and corrosion resistance.
  5. Sealing ring: Used for sealing the connector to protect the internal components from external influences such as water, corrosion, dust, etc.

• 2. How to distinguish the male and female connectors?

  1. Appearance difference: Male connectors usually have protruding pins, while female connectors have recessed slots. This is one of the most common ways to distinguish.
  2. Marking difference: Some connectors may have markings on the shell, such as "M" for female and "F" for male.
  3. Internal structure difference: In some special cases, the internal structure of male and female connectors is also different.
  Of course, the most reliable way is to check the specifications and technical information of the connector, which usually clearly indicate the gender of the connector.

• 3. Connector shell specification model?

  1. ‌RJ45 connector‌: This is a common network connector used for information socket connections in wiring systems. The RJ45 connector consists of a plug and a socket. The plug has 8 grooves and 8 contacts and is widely used in computer networks.
  2. ‌DB series connector‌: Including DB9, DB15, DB25, DB37 and other models. These connectors are usually used for serial communication, with different pin numbers and external dimensions, suitable for different data transmission requirements.
  3. D-Sub connector: D-Sub series connectors have DB9, DB15, DB25 and other models. The shell material can be plastic or metal, which is suitable for signal transmission between various electronic devices.
  ‌4. Tyco Electronics connector shell: For example, model 1473672-1, this connector shell is suitable for switching power supplies, relays, filters, etc., with a 2.2mm pitch and 1-row design.
  5. Micro-adapter relay shell: With a 4.80mm pitch, it is suitable for micro-adapter relay applications and prov
