Description

Adding a high-frequency connector for lapped gold fingers in a grounded metal casing

This creation is about a connector, especially a high-frequency connector that adds a gold finger to the metal casing to enhance the anti-EMI performance.

According to the connector, the connector refers to all the connecting components and their accessories on the electronic signal and power transmission. It is the transmission bridge of all currents and signals on the general electronic device. The design and production quality will naturally be good. It has a very important impact on the reliability of current and signal transmission, and is also closely related to whether the electronic device can maintain normal operation. Generally speaking, all kinds of electronic devices (such as smart phones, tablets, desktop computers, notebook computers, digital cameras, etc.) will be configured with corresponding types according to their design requirements. Frequency connectors, in order to enable the electronic devices not only to maintain their normal operation, but also to exchange data with each other, so that the connectors can be between components and components, between devices and devices, or between systems and systems. The current and signal are transmitted to form a complete telecommunications system. Therefore, the connector is the most basic component required for the telecommunications system.

According to the industry research report, in the past decade or so, compared with other component industries, many Taiwanese companies entering the connector industry are still quite profitable ethnic groups. The reason is mainly related to electronics. In the field of devices, regardless of the positioning and division of the electronic devices of their respective international manufacturers or Taiwanese manufacturers in the market, it has become increasingly clear, and This has become a very clear point. This phenomenon has also led to considerable technical differences between the high and low-order connectors used in their respective electronic devices. This feature has enabled the manufacturers to commission the Taiwan connector manufacturers. All kinds of connectors are strictly required to be able to produce connectors that meet their special requirements and have a wide range of application capabilities. This demanding product requirement forces Taiwan connector manufacturers who are commissioned to OEM. We are working harder on product improvement and research and development, in order to have a variety of specialized projects to produce various connector products that meet different requirements of customers. According to this, Taiwan connector manufacturers have been groping for more than ten years. Under the study and tempering, I have already trained the technical ability to avoid the competition of the low-cost Red Sea (Chinese related manufacturers).

However, as early as the decade of the 2008 financial turmoil, the relevant Taiwan connector manufacturers who used connectors as their main products had clearly felt and experienced a serious industrial crisis. At that time, the PC industry was weak due to the overall market demand. The barriers to entry and the fierce competition in the industry have been devastating, and this has affected the connector industry in Taiwan. As a result, many Taiwan connector manufacturers are facing a crisis of survival that cannot continue to operate, and they suddenly realize that they should adjust their business strategies immediately. And expect to be able to take advantage of the multi-transformation strategy, so that the application level of connector products is no longer limited to the PC industry, but should be more widely covered with various communication or consumer electronics (such as: mobile phones and game consoles. .., etc. According to this, Taiwan connector manufacturers, which originally relied heavily on computers and their peripheral devices, have been transformed into products for research and development and production of various consumer electronic products, displays, etc. in the past decade or so. The niche type connector used.

However, as mentioned above, the 2008 financial turmoil has indeed broken the industry tacit or unspoken rules that have long been followed by many players in the connector industry, such as the US, Europe and Japan that originally produced high-end or high-end technology connectors. Connector manufacturers, under the pressure of increasing shortage of profits, also considered the production of low-end connectors, and seriously invaded Taiwan connector manufacturers. In the main product line that has been mastered for many years, in addition to the change of the situation, Taiwan connector manufacturers must add a new strategy to balance the points and aspects that have not been reviewed in the past. For the future, the various characteristics of the connector, research, development and improvement, in order to produce more and better meet the market needs of the excellent connector products, can now occupy a place in the market, for example, as mentioned above, the connector It is an important basic component for transmitting current and signals between the electronic devices themselves and each other. It has an extremely important and critical influence on whether the electronic devices themselves and each other can maintain normal operation. In recent years, due to various electronic devices in the market Under the urgent need of continuous improvement of transmission speed, how to maintain the accuracy and stability of signal transmission quality and speed under the premise of high-speed data transmission, it is naturally widely concerned and valued by relevant scholars and practitioners; Transmission as an example, from the early USB 1.0 maximum transfer speed of 12Mbps, gradually evolved to USB 2.0 The maximum transmission speed is 480Mbps. Later, during the USB 3.0 (Super Speed USB) period, the maximum transmission speed of data is increased to 5Gbps. Even in the USB 3.1 Gen 2 period, the maximum transmission speed is directly increased to 10Gbps. There is a strong demand for high speed data transmission.

Traditionally, the electronic connector technology has mainly focused on the mechanical structure design of the signal terminals in each connector. However, with the development of technology, the transmission speed of digital signals has been moving toward high speed and high frequency. The digital signals transmitted by the electronic connectors themselves are also lost during transmission. Therefore, how to minimize the loss, so that the digital signals can obtain stable and accurate transmission quality, has become a high-frequency electronic connector industry. An important topic in development. According to the development of high-frequency electronic connector products, it is a difficult and arduous technical threshold. In particular, it is two in the design of mechanical structure and its analysis of high-frequency electromagnetic electricity. Very different areas of expertise, therefore, how to take engineering design The best balance point is a daunting challenge. In view of this, how to ensure the high-frequency electronic connector has good structural strength, it can simultaneously improve its high-frequency signal transmission quality accuracy and transmission. The performance of speed stability has become an important topic for this creation, and it is expected that the innovative technology derived from this creation can effectively shorten the time course of developing high-frequency electronic connectors in the industry and enhance domestic The ability to analyze and design high-frequency signals to connect with world technology.

In order to stand out in the highly competitive high-frequency electronic connector market, the creators rely on years of experience in the design, processing and manufacturing of various power supply or signal connectors, and adhere to the spirit of excellence in research. After a long period of hard work and experimentation, I finally developed a high-frequency connector that adds a gold finger to the grounded metal casing.
