PCB terminals we can almost see electronic equipment is inseparable from it, electronic watches, calculator, general computer, small to big to the computer, communication electronic equipment, military weapon systems, as long as there are integrated circuits and other electronic components, electrical interconnection between them are used for PCB. Besides fixed all sorts of small parts, it provides integrated circuits and other electronic components fixed assembly of mechanical support, implementation of integrated circuits and other electronic components between wiring and electrical connection or electrical insulation, provide the required electrical properties, such as the characteristic impedance, etc. At the same time to provide automatic soldering resistance welding graphics; Instrumentation for components, inspection and maintenance to provide identification characters and graphics.
Plug type series terminals play an important role in the PCB terminal blocks, consists of two parts can be connected with the plug, the section line pressure, then plugged into another part of this section in the welding on the PCB. The pick up at the bottom of the mechanical principle of the vibration design ensures that the product of long-term air tight connection and the use of the finished product reliability. Can add assembly ears on both ends of the socket, assembling the ear to a large extent can protect splicing and can prevent the splicing arrangement position, at the same time, this design can ensure outlet socket right into the matrix. Socket button can also be assembled and locked. Assembly button bits can be more firmly fixed on the PCB, lock button to lock the mother after the installation is completed and socket. All kinds of socket design can match different maternal insertion method, for example: horizontal, vertical or inclined to printed circuit boards, etc., can choose different ways according to the customer's requirements. Can choose metric gauge can also choose to standard gauge, is currently on the market's best-selling terminal type.
As electronic devices more and more complex, more and more parts need, PCB terminals above line and parts is becoming more and more intensive. Although our PCB terminals industry achieved rapid progress, but at the moment are obviously larger than that of advanced countries still has great improvement and upgrade the space in the future.
