Origin and Characteristics of Connectors Where do connectors come from and what are their characteristics?

With the rapid growth of consumer electronics, automotive electronics and communication terminal markets, as well as the continuous transfer of global connector production capacity to Asia and China, Asia has become the most promising connector market, and China will become the world's fastest growing and largest connector market. The automotive market is the largest connector segment, with a typical light vehicle having approximately 1,500 connection points. China's connector market is expected to continue to grow faster than the global average. Over the next five years, China's connector market will grow at a CAGR of 15%. By 2019, China's connector market volume will reach 93 billion yuan. Do you know how connectors came to be? Do you know the market for connectors? Do you know the simple characteristics of connectors?

I. Connector Market Analysis With the rapid growth of consumer electronics, automotive electronics and communication terminal markets, as well as the continuous transfer of global connector production capacity to Asia and China, Asia has become the most promising connector market, and China will become the world's fastest growing and largest connector market. The automotive market is the largest connector segment, with a typical light vehicle having approximately 1,500 connection points. China's connector market is expected to continue to grow faster than the global average. Over the next five years, China's connector market will grow at a CAGR of 15%. By 2019, China's connector market volume will reach 93 billion yuan. II. Advantages of connectors Improvement of production process - Connectors simplify the assembly process of electronic products. Simplify the mass production process; Easy to maintain - if an electronic component fails, the faulty component can be quickly replaced when installing the connector; Easy to upgrade - with the advancement of technology, the components can be updated when installing the connector, replacing the old components with new and better ones Replace old components with new and better ones; Improve design flexibility using connectors gives engineers more flexibility in designing and integrating new products and systems with components. III. The Origin of Connectors The birth of connectors was conceived from the manufacturing technology of fighter planes. Aircraft in combat must be refueled and maintained on the ground, and the amount of time spent on the ground is an important factor in the success or failure of a battle. Therefore, in World War II, the U.S. military authorities decided to shorten the time spent on the ground for maintenance and increase the combat time of fighter planes. They began by unitizing the various control instruments and components and then connecting them into a complete system through connectors. When repairs were made, the faulty unit was taken apart and replaced with a new one, allowing the airplane to take off for combat immediately. After the war, AT-T Bell Labs successfully developed the Bell Telephone System, and the subsequent rise of computers, communications, and other industries led to more opportunities for connectors derived from stand-alone technology, and the market expanded rapidly. It is the following picture

IV. ORIGIN AND CHARACTERIZATION OF CONNECTORS Meaning of connector A connector is a device (including accessories) used to connect circuits or electronic machines. It is called a connector. Broadly speaking, a connector is a bridge between all signals, including a variety of unitized electronic and electrical modules and components that are connected into a complete system in a short period of time. V. Connector classification 1. According to the nature of use, there are external connectors (for external chassis) and internal connectors (for internal chassis). 2. Crimp and I.D.CT type according to the processing method is also known as perforated, soldered and plug-zero. 3. According to the use of can be divided into wire to board connectors, board to board connectors, wire to wire connectors, sockets and I / O connectors. 4. According to the form of can be divided into PCB According to the form can be divided into PCB connectors, flat cable connectors, coaxial cable connectors, embedded connectors, crimp connectors, circular connectors, angular connectors and printed circuit board connectors. 5. According to the structure can be divided into general-purpose connectors, moisture-proof and waterproof connectors, environmentally friendly connectors, gas-tight connectors, fire-resistant connectors, waterproof connectors. VI. The composition of the connector connector by the insulator, plug connector, socket connector and conductor composition. 1. insulator used to maintain the fixed position of each combination, and complete the combination of electrical insulation between the combination. 2. plug combination of rectangular or round steel pins or terminals used to insert the socket combination of components (terminals or springs). 3. socket connector is a connector component with elastic function in order to plug connectors and maintain good contact.4. Cords are generally used as electrical cords, such as electronic cords, flat cables, and isolation cords. VII. Characteristics of the connector 1. One of the male or female contacts is flexible, and the interconnection of the contacts ensures the connection of the circuit. 2. The terminal part of the contact has a wiring structure that is easy to realize wiring or printed circuit boards. That is, for welding, encapsulation, clamping, through-hole welding and other structures.3. Contacts are fixed in the correct position of the insulator, can be used to maintain the voltage insulation resistance between the contacts.4. The use of coupling structure, the contacts are easy to plug and unplug, and will not change position after vibration or impact.
