BACKGROUND OF THE INVENTION
(a) Technical Field of the Invention
The present invention relates generally to a structure of a signal connector that helps improve the quality of high-frequency signals and is easy to manufacture.
(b) Description of the Prior Art
The Universal Serial Bus (USB) interface, as a standard input/output interface, has been widely used in the designs of a variety of electronic devices. In 1994, Seven world-famous computer and communications companies, including Intel, Compaq, Digital, IBM, Microsoft, NEC, and Northern Telecom, jointly established the USB Association (USB-IF) and initially set up the USB interface specification, making it widely recognized by personal computer (PC) manufacturers. The interface has gradually become a required interface for hardware manufacturers.
Taking scanners, printers, and meal ordering machines as examples, USB Type-B connectors are often used for transmission of signals. However, technology is changing with each passing day and the amount of information required is continuously increasing. Therefore, new models featuring faster transmission speeds have been emerging from USB Type-B connectors for transmitting high-frequency signals, as compared to ordinary ones.
However, the above-mentioned USB Type-B connector suffers, in practical uses thereof, the following problems and deficiencies that need to be improved:
The USB Type-B connector is more complicated in the manufacture thereof, because insertion pins for connecting with a circuit substrate are often connected in a dual in-line package (DIP), and the front and rear rows are the same so as to result in necessity of drilling operation for both the front and rear rows. This not only increases the time cost, but also generates more noise interference and causes greater feedback losses.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a design of making an upper-row first high-frequency transmission conductor group soldering portion, an upper-row central grounding transmission conductor soldering portion, and an upper-row second high-frequency transmission conductor group soldering portion in a surface-mount technology (SMT) form to allow the high-frequency characteristic impedance to be symmetrical and matched, thereby reducing noise interference and having lower feedback losses and making the manufacturing process more convenient.
The primary structure that the present invention adopts to achieve the aforementioned primary objective comprises an upper-row transmission conductor group and a lower-row transmission conductor group arranged below the upper-row transmission conductor group, wherein the upper-row transmission conductor group comprises an upper-row first high-frequency transmission conductor group, an upper-row first high-frequency transmission conductor group bend portion, an upper-row first high-frequency transmission conductor group soldering portion, an upper-row central grounding transmission conductor, an upper-row central grounding transmission conductor bend portion, an upper-row central grounding transmission conductor soldering portion, an upper-row second high-frequency transmission conductor group, an upper-row second high-frequency transmission conductor group bend portion, and an upper-row second high-frequency transmission conductor group soldering portion, and the lower-row transmission conductor group comprises a lower-row first signal transmission conductor, a lower-row first signal transmission conductor soldering portion, a lower-row power transmission conductor, a lower-row power transmission conductor soldering portion, a lower-row second signal transmission conductor, a lower-row second signal transmission conductor soldering portion, a lower-row grounding transmission conductor, and a lower-row grounding transmission conductor soldering portion, such that during transmission of signals through the upper-row first high-frequency transmission conductor group and the upper-row second high-frequency transmission conductor group, due to the surface-mount technology (SMT) arrangement of the upper-row first high-frequency transmission conductor group bend portion, the upper-row first high-frequency transmission conductor group soldering portion, the upper-row second high-frequency transmission conductor group bend portion, and the upper-row second high-frequency transmission conductor group soldering portion, so that mounting the entirety to the circuit substrate can be implemented with a simple process and there is no need to drill holes in the circuit substrate, and bettered characteristics impedance, enhanced high-frequency quality, reduced noise interference, and lowered feedback loss can be achieved.
Through the above technology, the problems that the conventional USB Type-B connector is more complicated to manufacture due to the pins that are inserted and connected to a circuit substrate being mostly made connectable using dual in-line package (DIP), and being identical for both the front and rear rows, so as to cause necessity of implementing drilling operations on both the front and rear rows, resulting in not only an increase of the time cost, but also more noise interference and greater feedback loss can be overcome to achieve the practical progress of the above-mentioned advantages of the present invention.
