The manufacturing of terminal molds affects the quality of the terminals, especially in the essential position of the terminal. With the development of the intelligent and precise direction of the domestic mold industry in China, it has also improved the manufacturing level of the terminal industry in my country to a certain extent. In order to keep up with market competition, my country’s industry is undergoing important changes in recent years, such as the shift from molds to market-based or customer-requested flexible consumption; mold design is independent to the integration of design and integration; consumption in a certain place to global purchase And consumption changes; manufacturing factories’ demands for quality and safety are also improving from time to time. These changes are advancing and entering a new stage of application, namely the intelligent deployment stage. It has also driven the terminal manufacturing industry to intelligent and automated production technology from time to time.

Although the total amount of smart molds is not much at present, PCB terminal blocks represent the new development direction of mold technology, and they play an increasingly important role in the adjustment and development of industry product structure. Once the smart mold is deployed, it will inevitably have a strong driving effect on the entire mold industry. Therefore, it is particularly important to give priority to the deployment of smart molds in the development of the industry. It is imperative that the mold used in the terminal industry is also imperative. In order to ensure the quality and reliability of the wiring terminals and prevent the occurrence of the above-mentioned fatal shortcomings, it is recommended to discuss and formulate the corresponding selection technical requirements according to the technical conditions of the product, and carry out the following targeted reliability inspections to prevent failure. At present, there is no such item in the acceptance test of ordinary terminal consumer manufacturers, and users generally need to stop the continuity test after installation. Therefore, it is suggested that consumer manufacturers should increase some key models of products. Some terminal blocks are used in dynamic vibration environment. The actual test proves that only the static contact resistance is qualified, and it cannot guarantee the reliability of the contact in the dynamic environment. Since the connectors with qualified contact resistances often still show instantaneous charging when they stop vibration, impact and other simulated environmental experiments, for some high-reliability terminals, the dynamic vibration experiment is used to assess their contact reliability. Single hole separation force refers to the separation force of the contact member in the inserted state from being stationary to moving, which is used to characterize the contact between the pin and the socket.
