In the field of electronic components industry, it is often involved in the test of product insertion and extraction force. What are the key points of the insertion and extraction force test of pin array and bus array in electronic connectors? Let me give you an introduction from a professional point of view, so that you can have a deep understanding of what are the key points of the test of the insertion and withdrawal force of the pin row and the bus row in the electronic connector.
Key points for testing the insertion and withdrawal force of connector pin and busbar
A、 Test points:
1. The test object is the whole connector (focusing on the pair of plug contacts)
2. The test action axis is the direction of normal use of the connector (the opposite direction of terminal assembly).
3. Unless otherwise specified, the speed is 25.4mm/minute
4. It is a destructive test.
B、 Specification requirements:
1. Generally set the minimum value (4.9n min.).
2. The terminal retention force is defined to ensure that the terminal (conductor) is fixed in the plastic. The terminals that have been assembled in the plastic are in the process of cracking (such as welding / pulling during product handling / SMT) and use (such as male and female mating).
3. The pins and busbars will receive external force when they are processed (vibration and street impact). Therefore, the retention force of the terminal and the plastic must be sufficient, so that the pin will not be returned after the terminal is subjected to unexpected force, resulting in connection interruption and connection function failure.
