Understand that the real secondary lock does not have a secondary protective effect, but more effectively protect it. The real meaning of this is that after the primary lock, if the primary lock fails or no operation verification is in place, the secondary lock is It is very important to ensure that the first lock is protected after the first lock is locked. The force arm mechanism is the most commonly used in the secondary locking structure combined with the primary lock. Because the primary locking is related to the insertion force, a form similar to the force arm mechanism is required according to the mechanical design concept, so as to achieve both labor-saving and The connector can be easily snapped into place. For the requirements of the lever arm, USCAR has talked about a lot of the ergonomic operability of the lever arm. USCAR also stipulates the force requirements for the relevant primary locks and secondary locks in the case of opposite insertion and non-insertion. Actually we are big
Everyone thinks that USCAR is the standard for connectors, but I think that the USCAR standard is not only a technical standard, but also guides designers to make the structure reliable in the design process, how can the structure and performance be reliable under the premise of reliable.
