Technical Field

[0001] This invention relates to the field of pin testing technology, and in particular to high-density, high-strength connector pins and their testing equipment. Background Technology

[0002] Currently, the contact components with high contact requirements commonly used in electrical connectors typically include pins and sockets. The sockets, as the contact ends of the elastic body, have grooves. These grooves form elastic contact springs. When the pin is inserted into the socket, the elastic springs clamp the pin, thus maintaining contact with the pin and realizing the function of the connector.

[0003] For the product testing and processing of connector pins, in order to ensure their strength, a hardness testing device is generally required to test them, that is, to ensure the pressure resistance of the pins. The existing testing process generally involves placing the pin to be tested directly on the testing workbench, and then testing the pin with a pressure-sensing probe. Generally, both the pin tip and the pin body need to be tested. In this process, there is a lack of suitable positioning components to position the pin to ensure the stability of the pin test. Furthermore, in the use of existing pins, the pin tip and pin body are generally hollowed out to save materials while ensuring the performance, which has a certain impact on their pressure resistance.
