PCB board (Printed Circuit Board), the Chinese name for printed circuit board, referred to as printed circuit board, is one of the important parts of the electronics industry. Insulated board as a substrate, cut to a certain size, with at least one conductive graphics, and cloth with holes (such as component holes, fastening holes, metallization holes, etc.), used to replace the previous device electronic components of the chassis and to achieve the interconnection between electronic components. As this board is made using electronic printing, it is called a "printed" circuit board.

PCB Spring Terminal Blocks  is the use of spring device of the new terminal block, and it has been widely used in the world of electrical and electronic engineering industry: lighting, elevator lift control, instrumentation, power, chemical and automotive power, etc.. PCB Spring Terminal Blocks metal parts are spring device design, plastic body are used PA66 insulation material. The series of PCB Spring Terminal Blocks are easy to operate, free maintenance and have a gas-tight contact device system, that is, durable and reliable and cost-effective.

Pluggable Terminal Blocks by two parts plug-in connection, part of the line will be pressed, and then inserted into the other part, this part in soldering to the PCB board. This connection bottom mechanical principle, this anti-vibration design to ensure the long-term airtight connection of the product and the reliability of the use of the finished product. The assembly lugs can be added to both ends of the socket, which largely protect the tabs and prevent poor alignment of the tabs, while the socket design ensures that the socket can be inserted correctly into the female body. The sockets can also have assembly and locking fasteners. The assembly fasteners provide a more secure attachment to the PCB board, while the locking fasteners lock the female and the socket after installation. A variety of socket designs are available with different insertion methods for the masters, such as horizontal, vertical or angled towards the PCB, depending on the customer's requirements. Both metric and standard wire gauges can be selected.
