Compared with the traditional connection mode, the heavy-duty terminal can save 20-30% of installation cost for a machining center; the production efficiency is increased, and the error rate of wiring is reduced. Heavy duty terminals are designed specifically to withstand the worst, most demanding industrial environments and are tougher, stronger, and more resistant than conventional connectors. The heavy-load terminal adopts a modularized design, and comprises a pneumatic module, a high-current module, a field bus module and a USB interface module, so that the heavy-load terminal can be quickly connected without barriers when using modular equipment. Therefore, compared with the common connector, the connector has the advantages of higher practicability and more convenient maintenance. The international advancement in structural design, material use, and heavy-duty terminals has made connectors remarkable in terms of electrical performance. The reliability of electrical connection systems is not achieved by conventional connection means. Therefore, the device is widely applied to equipment which needs to be electrically and signally connected, such as construction machinery, textile machinery, packaging printing machinery, tobacco machinery, robots, rail transit, hot runners, electric power, automation and the like.
