What is the basic knowledge of electronic components? Connector?
日期：2019-01-24 11:19
Connector, as the key component of current or signal connection, is also an important part of industrial system. Connectors, ranging from airplanes, rockets to mobile phones, televisions, and so on, come into being in various forms, bridging circuits or other components and assuming the role of current or signal connection.
Connector
Connector, CONNECTOR. It is also called connector, plug and socket in China. Usually refers to electrical connectors. That is to say, a device connecting two active devices to transmit current or signals.
Connector is a kind of component that our electronic engineering technicians often contact. Its role is very simple: in the circuit is blocked or isolated between the circuit, set up a bridge of communication, so that the current flow, so that the circuit to achieve the intended function. Connector is an indispensable part of electronic equipment, along the current flow path, you will always find one or more connectors.
Connector forms and structures are ever-changing. With the different application objects, frequencies, power, application environment and so on, there are various forms of connectors. For example, connectors for lighting on the court are very different from those for hard drives, and connectors for igniting rockets. But no matter what kind of connector, it is necessary to ensure smooth, continuous and reliable current flow. Generally speaking, connectors are connected not only by current, but also by light, glass and plastic instead of wires in ordinary circuits. In todays rapid development of optoelectronic technology, the carrier of signal transmission in optical fiber systems is light, but connectors are also used in optical signal paths. Their functions are the same as circuit connectors.
The birth of connectors is conceived from the manufacturing technology of fighter aircraft. Aircraft in battle must be refueled and repaired on the ground, and the time spent on the ground is an important factor in a battle. Therefore, in World War II, the U.S. military authorities were determined to shorten the ground maintenance time and increase the combat time of fighters.
They first unite all kinds of control instruments and components, and then connect the connectors into a complete system. When repairing, disassemble the faulty unit and replace the new unit, the aircraft will be able to launch immediately. After the war, AT-T Bell Laboratory successfully developed Bell Telephone System. Then the rise of computer and communication industries gave more opportunities for the development of connectors derived from stand-alone technology, and the market expanded rapidly.
Classification of Connectors
Due to the increasingly diversified structure of connectors and the emergence of new structures and applications, it is difficult to adapt to try to solve the classification and naming problems with a fixed pattern.
1. According to the nature of use
External connector (for external case) and internal connector (for internal case).
2. Differentiation by Connector Hierarchy
Level 1. Component-to-package interconnection (DEVICE TO PACKING):
It refers to the connection between IC CHIP and connector.
Level 2. Encapsulation-to-substrate interconnection (COMPONENT LEAD TO CIRCCUITRY):
Refers to the connection between COMPONENT and PC board.
Level 3. Board to Board:
Refers to the interconnection between PC board and PC board.
Level 4. Connection of subsystems to subsystems (SUBASSEMBLY to SUBASSEMBLY)
Level 5. Connection between subsystems and I/O (SUBASSEMBLY TO I/O PORT)
Level 6. System to System Connection.
4. According to the way of use
Line-to-board connectors, board-to-board connectors, pair-to-line connectors, sockets, input and output connectors.
5. By Form
PCB board connector, flat cable connector, coaxial cable connector, embedded connector, pin type connector, circular connector, corner connector, printed wiring board connector.
