1) Continuity detection
At present, there is no such item in the product acceptance test of general terminal manufacturers, and users generally need to conduct continuity testing after installation. Therefore, it is suggested that manufacturers should add 100% point-by-point continuity detection to some key models of products.

2) Instantaneous interruption detection
Some terminal blocks are used in dynamic vibration environments. Experiments have confirmed that only checking whether the static contact resistance is qualified cannot guarantee reliable contact in a dynamic environment. Because the connectors with qualified contact resistance often still have instantaneous power failures during simulated environmental tests such as vibration and shock, it is best to conduct 100% dynamic vibration test assessments for some terminals that require high reliability. its contact reliability.
3) Single hole separation force detection
The single-hole separation force refers to the separation force that the contacts in the mated state change from static to moving, which is used to indicate that the pins and sockets are in contact. Experiments show that the single-hole separation force is too small, which may cause the signal to be cut off instantaneously when subjected to vibration and shock loads. It is more effective to measure the contact reliability by measuring the separation force of a single hole than to measure the contact resistance.
