The pin and female connector, as a connector plug, is mainly used to achieve reliable connection between boards, and is currently widely used in various products in the electronics industry. Under the influence of factors such as spacing, pin count, and row count, the shape of pin female connectors is usually relatively slender. Therefore, in practical application scenarios, when the connector undergoes frequent insertion and extraction actions or continuous vibration, the force values of different intensities may cause the contact terminals to deviate from their normal working positions, thereby causing abnormal or even complete failure of the connector function. Therefore, it is particularly crucial to conduct insertion and extraction force testing on pin and female connectors.
The following are the core points for testing the insertion and extraction force of pin and female connectors:
1、 Clearly define the test object: The object of the insertion and extraction force test should be the entire pin and female connector product. Among them, the mating contact point between the male and female connectors is the core part for achieving electrical connection and is the key focus area for testing.
2、 Determine the testing axis: The direction of force applied during testing must follow the force direction of the pin and female connector product under actual normal use. Because the force exerted on connectors in practical applications usually has a specific direction, only by testing according to the actual direction of use can the working condition of the connector be truly simulated, thereby obtaining accurate and reliable test results.
3、 Standardized testing speed: Except for products with specified testing requirements, under normal circumstances, the standard testing speed for pin and female connectors is generally set at 25.4mm/minute.
4、 Set the minimum value for destructive testing: During the destructive testing phase, the minimum value is usually set to 4.9N Min. By setting this minimum value, the structural stability and reliability of the connector under extreme stress conditions can be effectively evaluated, providing important basis for the design and optimization of the connector.
