PCB terminal we can see almost all electronic equipment without it , small electronic watches, calculators , general computer , large computers, electronic communication equipment, military weapon systems , integrated circuits and other electronic components as long as they to be used in the electrical interconnection between the PCB. In addition to fixing a variety of small parts , but it offers a variety of integrated circuits and other electronic components fixed mechanical support assembly to achieve integrated circuits and other electronic components and electrical connections between wiring or electrical insulation , provide the required electrical characteristics as characteristic impedance . While providing for the automatic soldering solder graphics ; Cartridge for the components , inspection, maintenance provide identification characters and graphics.
Pluggable terminal block series played in important role in PCB terminal blocks , connected by a two-part plug part of the cable clamp , and then into the other part, which in soldered to the PCB board. This connector at the bottom of mechanical principles, this anti-vibration design ensures long-term product and finished products using gas-tight connection reliability . Both ends of the socket assembly can be added ears , assembling in large part to protect the ear tabs and tab arrangement can prevent poor location , but this outlet is designed to ensure that the socket can be inserted into the correct parent . Sockets also have assembled and Lock buckle clasp bit . Buckle assembly can play a bit more firmly fixed to the PCB , the lock button to lock the mother and socket bit after the installation is complete. Socket design can be used with a variety of different maternal insertion method , for example : horizontal, vertical or tilted to the printed circuit board , you can choose a different way according to customer requirements. You can select either metric gauge can also choose standard gauge , is currently the terminal type on the market selling .
As electronic devices become more complex , the need for more and more parts , PCB terminals on top of the line and the parts are more intensive . Although China PCB terminal on the industry has made considerable progress, but compared with the developed countries there is a large gap , the future is still much space for improvement and upgrading .
