What are the connector insertion and extraction force standards? What can affect connector insertion and extraction force?

The connector insertion and extraction force is the force that needs to be applied during the connection between the connector plug and the receptacle. The insertion and extraction force of the connector directly affects the reliability and service life of the connector. Therefore, there are many standards that specify and test the insertion and extraction force of connectors. The following are some common connector insertion and extraction force standards: 1. MIL-DTL-38999: This is an aerospace connector standard that specifies that the connector insertion and extraction force should be between 2 and 50 pounds of force. 2. IEC 60512: This is a standard issued by the International Electrotechnical Commission, which specifies that the insertion and extraction force of connectors should be between 1 and 15 N. 3. IPC J-STD-001: This is a standard for electronic products that specifies that the connector insertion and extraction force should be between 0.2 and 2 LBF. The insertion and extraction force of the connector is affected by many factors, mainly including the following aspects: 1. Material: The material used in the connector has a great impact on the insertion and extraction force. For example, soft materials generally require less insertion force, while hard materials require more insertion force. 2. Lubricant: The lubricant can reduce the friction when the connector is plugged and unplugged, thereby reducing the plugging force. 3. Size and shape: The size and shape of the connector also have a great influence on the insertion and extraction force. For example, the larger the contact area between the connector plug and the receptacle, the greater the insertion force. 4. Welding method: The welding method of the connector will also affect the insertion and extraction force. For example, poor soldering methods or high soldering temperatures can cause the connector to deform or deform, thereby increasing the insertion and extraction force. Connector insertion and extraction force is a very important parameter in connector design and manufacturing. Reasonable insertion and extraction force can ensure the reliability and service life of the connector, and reduce the user's difficulties in the use process.
