Why do connectors need to be tested for insertion and extraction force?

Connectors are also called connectors. Also called connectors and sockets in China. They generally refer to electrical connectors, which are devices that connect two active devices and transmit current or signals. When the male and female ends come into contact, messages or current can be transmitted. In order to ensure the reliability and stability of the connector after adaptation, this standard is specially formulated according to EIA-364-13C (International Electrotechnical Association plug-in and pull-out force test specifications), which stipulates that the plug-in and pull-out force shall not be greater than the rated value (to ensure that users will not have difficulty inserting adapter), the pull-out force must not be less than the rated value (to prevent loosening or falling under various complex situations, causing interruption and damage to the device connection).

Test insertion and extraction force procedures

Insertion and extraction force test

Test Purpose: To test the force required when inserting and extracting each terminal using a standard test male plug to evaluate the quality characteristics of the terminal and confirm that the force generated by the connector during use is sufficient to maintain the connector's functionality and suitability for consumption.

Testing basis: EIA-364-13 or MIL-STD-1344A, 2013.1.

Testing equipment: Pullout force testing machine

High-Performance Battery Plug 50A

Test Methods:

1. The size and surface roughness of the connector PIN or BLADE used for testing comply with the requirements of MIL-3197.

2. The PIN pin or BLADE of the test connector should be cleaned regularly to prevent its surface from being covered with film and affecting the accuracy of the measurement data.

3. Test step 1 (using connector PIN or BLADE):

A. Plug and unplug once to adjust the terminal status.

B. Insert the largest size test connector PIN or BLADE while measuring the insertion force. Pull out the test connector PIN or BLADE and replace it with the smallest size test connector.

Test insertion and extraction force. Since ALIGNMENT has a great influence on the accuracy of the test, special attention should be paid to the consistency of the LOAD CELL of the slave machine, the test PIN and the center line of the test sample during the test.

Test points:

1. The test object is the entire connector and complete components.

2. The test axis is the direction of normal use of the connector.

3. Unless otherwise specified, the test speed is defined as 25.4 mm/min.

Require:

1. The insertion force is generally set to the maximum value. (Maximum 35N).

2. The extraction force is generally set to the minimum value. (7N Min.initial; 3N Min.Final), some customers also require setting the maximum value.

The insertion force is the force generated when two matching connectors are completely separated from each other to the working state; the extraction force is the force generated by the two matching connectors from the working state to being completely separated. Insertion and extraction force is generated when consumers use the product. The insertion and extraction force is only generated when there is a docking end (io/plug, jack/plug). Generally there is no docking terminal, such as battery/SIM CONN. Insertion and extraction forces are not defined.
