What is circular connector d38999

‌D38999‌ is a circular connector, also known as a lightweight military circular connector, which belongs to the MIL-DTL-38999 series. This connector was originally born in the 1960s to provide a rugged and durable military solution. Over time, the D38999 connector has become more and more popular due to its smaller contacts and higher density insertion mode, and has become the standard for military specification connectors in military and aerospace applications. Despite multiple developments and improvements, including new shell styles, coupling methods, derivatives, and new features, the D38999 connector has maintained its popularity. For example, Amphenol's new Series Five connector is the latest product in this series, which combines all the functions of the traditional 38999 connector in a lighter, smaller and more compact package to support the changing needs of the aerospace industry.

Advantages of D38999 connectors

The features of D38999 connectors include temperature resistance, environmental resistance, fast coupling, improved EMI shielding, radiation resistance, and optimized design and materials. It uses machining technology and has excellent high temperature resistance, and can operate stably over a wide temperature range. In addition, it also has good radiation protection and is suitable for environments that need to resist radiation. Quick coupling is achieved through triple start threads, with improved EMI shielding function, effectively reducing electromagnetic interference, and ensuring stable and reliable signal transmission. The contact body of the D38999 connector is made of copper with gold plating, and the insulator is made of thermoplastic, ensuring high conductivity and corrosion resistance and durability. At the same time, its chemical nickel plating process enhances wear resistance and anti-corrosion and anti-rust functions, making the product feel better and more durable.

FAQ about Circular Connectors

Loose connection:

Loose connection is one of the most common problems during use, which may be caused by a variety of factors, such as plug and socket are not fully aligned, internal reed fatigue or damage, shell wear, etc. Loose connection will cause signal interruption or power loss, affecting the normal operation of the equipment;

Solution strategy:

1. Make sure the plug and socket are properly aligned when connecting;

2. Check regularly and replace damaged or aged parts in time;

3. You can replace high-quality products with better quality and better performance;

Poor contact:

It may cause signal distortion or reduced power transmission efficiency due to internal fouling, oxide formation, reed deformation or wear, etc.;

Solution strategy:

1. Clean regularly to remove fouling and oxides;

2. Use lubricants or contact improvers to reduce reed wear and improve contact performance;

3. Avoid applying excessive force on the product to prevent reed deformation;

Mis-insertion and wrong insertion:

We sometimes have problems with mis-insertion or wrong insertion due to similar appearance, which may cause equipment damage or safety problems, especially in high-density This problem is more common in highly connected environments;

Solution strategy:

1. Use color coding or markings to distinguish;

2. Check the type and specification carefully before connecting to ensure correct matching;

IV. Improper environmental adaptability:

The product may perform poorly under specific environmental conditions, such as high temperature, high humidity, vibration or corrosive environments, which may lead to performance degradation or short life;

Solution strategy:

1. Select the appropriate product according to the application environment;

2. Use protective covers or sealants to protect it from environmental factors;

3. Check environmental adaptability regularly and replace inappropriate ones in time;

V. Difficulty in maintenance and replacement:

Maintenance and replacement in some complex equipment or systems may be very difficult, especially when the location of the product is particularly difficult to reach, which will more easily cause problems;

Solution strategy:

1. Consider maintainability when designing the equipment to ensure easy access and replacement;

2. Use modular design to make its replacement easier;

3. Perform preventive maintenance regularly to reduce the possibility of emergency replacement.
