    Research on Simulation Application Technology

    Simulation technology is based on various disciplines and theories, takes computer and its corresponding software such as AutoCAD and Pro / E program stress analysis software as tools, and simulates, analyzes and confirms its mechanical, electrical, high-frequency and other properties by establishing product models and corresponding boundary conditions, so as to reduce the cost of product development failure caused by factors such as unreasonable material selection and structure, Improve the success rate of development and help to provide support for products to realize complex system applications.

    4. Connector Intelligent Technology

    At present, this technology is mainly used in DC series power connector products. It can detect the intelligent signal before transmitting the power supply, so as to ensure that the positive and negative electrodes are connected and start the power supply after the plug is inserted in place, which can avoid the adverse consequences of arc injury and machine burning caused by the contact when the plug is not inserted in place. In the future, enterprises need to develop similar intelligent technologies for other products.

  • Precision connector technology

    Precision connector involves many links such as product design, process technology and quality control technology. The main technologies include the following aspects:

    (1) Precision mold processing technology: adopt CAD, cam and other technologies, introduce high-precision processing equipment in the industry, and use personnel production experience and advanced equipment and technical means to realize high-precision and high-quality mold products.

    (2) Precision stamping and precision injection molding technology: realize the precision, efficient and stable all-round control and perfect surface quality of all kinds of stamping and injection molding parts to ensure product quality.

    (3) Automatic assembly technology: through the application of precision control technology and semi-automatic testing machine technology, overcome the difficult problem of manual operation of precision products and improve the core competitiveness.

    Research on manufacturing technology

    The competitiveness of products depends on the level of manufacturing technology to a certain extent. Continuous development of new manufacturing technology and improvement of existing production and processing technology can greatly improve the manufacturing efficiency and quality assurance ability of products.

    (1) Fine manufacturing process: this process is mainly aimed at technologies such as small spacing and thin thickness. Some enterprises have conducted process research on connectors with spacing less than 0.4mm. This kind of technology can ensure that the company can reach the advanced level of the international industry in the field of ultra-fine manufacturing.

    (2) Integrated development technology of light source signal and electromechanical structure: this technology can be applied to the audio connector embedded in electronic components. By adding IC, led and other electronic components to the audio connector, the audio connector has the function of transmitting analog signals and digital signals at the same time, so as to break the current design of conducting transmission by mechanical contact of audio connector.

    (3) Low temperature and low pressure forming technology: the sealing and physicochemical properties of hot-melt materials are used to achieve the effects of insulation and temperature resistance. After packaging, the wire rod protects the welding point from external force. Moreover, the packaging of DC connector body and wire rod has the effects of insulation, temperature resistance and impact resistance, so as to ensure the quality and reliability of products, In the future, it will be continuously developed and applied in different products.
