Spring terminal is a new type of terminal with spring devices, which has been widely used in the world electrical and electronic engineering industries: lighting, elevator lifting control, instrumentation, power supply, chemistry and automobile power supply. The metal parts of spring series terminals are all designed with spring devices, and the plastic body is made of PA66 insulating material. Spring series terminals are easy to operate, maintenance-free, equipped with airtight contact device system, durable, reliable and cost-effective.
Plug-in series terminal PTB is formed by plugging two parts. One part compresses the wire and then inserts it into the other part, which is soldered to the PCB. This shockproof design is based on the principle of bottom mechanics, which ensures the long-term airtight connection of products and the reliability of finished products. Assembly ears can be added at both ends of the socket, which can protect the insert to a great extent and prevent the insert from being arranged badly. At the same time, this socket design can ensure that the socket can be inserted into the mother correctly. The socket may also have an assembly button and a lock button. The assembling buckle can be fixed on the PCB board more stably, and the locking buckle can lock the mother body and the socket after installation. Various socket designs can be matched with different insertion methods, such as horizontal, vertical or inclined printed circuit boards, and different methods can be selected according to customer requirements. You can choose metric instruments or standard instruments.
