Connector is a component commonly used in PCBA processing. Its function is very simple: to build a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can achieve the intended function. Connectors are indispensable parts in electronic equipment. When you observe the current flow path, you will always find one or more connectors. The form and structure of connectors are ever-changing. With different application objects, frequencies, power and application environments, there are various types of connectors. For example, the connector for lighting on the court is quite different from the connector for hard disk drive and the connector for igniting rockets. However, no matter what kind of connector, it is necessary to ensure that the current flows smoothly, continuously and reliably. In general, the connector is not limited to the current. Today, with the rapid development of optoelectronic technology, the carrier of signal transmission in optical fiber systems is light. Glass and plastic replace the wires in ordinary circuits. However, connectors are also used in the optical signal path, and their functions are the same as circuit connectors.
What if there is no connector? At this time, the circuits shall be permanently connected with continuous conductors. For example, if the electronic device is to be connected to the power supply, both ends of the connecting wire must be firmly connected with the electronic device and the power supply by some method (such as welding). In this way, no matter for production or use, it has brought a lot of inconvenience. Take the automobile battery as an example. Assuming that the battery cable is fixed and welded firmly on the battery, the automobile manufacturer will increase the workload, production time and cost for installing the battery. When the battery is damaged and needs to be replaced, the car should also be sent to the maintenance station for desoldering, removing the old one, and then welding the new one. Therefore, more labor costs should be paid. With a connector, you can avoid many troubles. Just buy a new battery from the store, disconnect the connector, remove the old battery, install a new battery, and reconnect the connector. This simple example illustrates the benefits of connectors. It makes the design and production process more convenient and flexible, and reduces the production and maintenance costs.
The future technological innovation will mainly focus on the following directions
1. Miniaturization development technology of connector
This technology is mainly developed for the trend of connector miniaturization, and can be applied to the microminiature connectors below 0.3mm. It belongs to the new variety of MINI USB series products. It can be used for multi contact expansion card slot connector, and can meet and exceed the strict requirements of multi contact surface adhesion technology for coplanar contact, with high accuracy and low cost.
2. High frequency and high speed wireless transmission connector technology
This technology is mainly aimed at a variety of wireless device communication applications, with a wide range of applications.
3. Research on Simulation Application Technology
The simulation technology is based on various disciplines and theories, with the computer and its corresponding software such as AutoCAD, Pro/E program stress analysis software as tools, through the establishment of product models and corresponding boundary conditions, the mechanical, electrical, high-frequency and other performances are simulated, analyzed and confirmed, so as to reduce the cost of product development failure caused by factors such as material selection, unreasonable structure, etc., and improve the success rate of development, It is helpful to provide support for product realization of complex system applications.
4. Intelligent connector technology
This technology is mainly used in DC series power connector products. Before power transmission, intelligent signal detection can be carried out to ensure that the positive and negative electrodes are connected and the power supply is started only after the plug is inserted in place. This technology can avoid the adverse consequences of electric arc injury and machine burning caused by conducting contact when the plug is not inserted in place. In the future, enterprises need to develop similar intelligent technologies for other products.
5. Precision connector technology
Precision connector involves many links such as product design, process technology and quality control technology. The main technologies include the following:
(1) Precision mold processing technology: CAD, CAM and other technologies are adopted, high-precision processing equipment in the industry is introduced, and personnel production experience and advanced equipment technology are used to achieve high-precision high-quality mold products.
(2) Precision stamping and precision injection molding technology: to achieve all kinds of stamping and injection molding parts precise, efficient and stable all-round control and perfect surface quality, and ensure product quality.
(3) Automatic assembly technology: through the application of precision control technology, semi-automatic testing machine technology and other applications, overcome the difficulties of manual operation of precision products and improve the core competitiveness.
