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. What is the role of the connector shell?

  1. Play a mechanical protection role: The shell isolation separates the inside and outside of the connector, playing a mechanical protection role. Especially for bumps, outdoor environments or the outside of electronic equipment, its sturdy shell can effectively resist external mechanical effects, thereby preventing damage to the insulator and contacts.
  2. Waterproof and dustproof: The shell can protect the internal structure of the connector from external environmental factors such as dust and water. Especially for connectors used underwater or in the field, the shell also has a higher sealing performance to varying degrees.
  3. Play the role of supporting and installing insulators: When the insulator with contacts is installed on the connector housing, the contacts pass through the housing in the plug and socket to obtain precise spatial position, thereby ensuring high precision of mutual matching.
  4. Play the role of connecting and separating the plug and socket: The connection, l

• 2. Connector shell material?

  ‌Plastic‌: Plastic connector shells usually have good insulation properties and low cost, and are suitable for some low-voltage and low-frequency application scenarios. Commonly used plastic materials are polyvinyl chloride (PVC), polyamide (PA), polypropylene (PP), etc. Plastic materials are light, but may not be as durable as metal materials.
  ‌Metal‌: Metal connector housings have high wear resistance, corrosion resistance and mechanical strength, and are suitable for high-voltage, high-frequency, and high-speed transmission applications. Commonly used metal materials include ‌aluminum alloy, ‌stainless steel, copper, etc. Metal materials are strong, but the cost is high and may not be as light as plastic.
  ‌Alloy‌: Alloy connector housings combine the advantages of metal and plastic, with good mechanical properties and corrosion resistance. Commonly used alloy materials include ‌zinc alloy, ‌magnesium alloy, ‌aluminum-magnesium alloy, etc. Alloy materials combine the strength of me

• 3. Connector housing spring positive force setting requirements?

  1. Insertion and extraction force test‌:
  The test object is the entire connector, including all components.
  The test action axis is the direction of normal use of the connector.
  Unless otherwise specified, the test speed is defined as 25.4mm/minute.
  Insertion force is generally set to a maximum value (35N Max.).
  Pull-out force is generally set to a minimum value (7N Min. initial; 3N Min. Final), and some customers also require a maximum value.
  
  ‌2. Locking force test‌:
  The purpose is to confirm that the contact interface of the connector does not separate when subjected to unexpected forces to ensure functionality under unexpected conditions.
  Generally set to a minimum value (30N Min.).
  
  ‌3. Retention force test‌:
  This part is not explicitly mentioned in the search results provided, but according to the general test requirements for connectors, retention force may involve measuring the ability of the connector to maintain its connection state under specific conditions.
