The terminal block is used to achieve electrical connection accessories, the industry is divided into the scope of the connector. With the increasingly high degree of industrial automation and industrial control requirements become more stringent, accurate, and gradually rise in the amount of terminal. With the development of the electronics industry, the use of the terminal is more and more and more and more types. At present, the most widely used in addition to the PCB terminal hardware terminal nut terminals, spring terminals.

Terminal block plug the existing wiring technology in the most cost-effective form of multi-angle cable access can be achieved with 90 ° and 270 ° plug interface matching a 5.0 mm and 5.08 mm centerline spacing to meet industry standards open and closed plug requirements can be superimposed on end-to-end, and will not affect the centerline spacing of additional cable access point of view can be supported in the standard 3.5mm and 3.81mm vertical and right angle plugs.
