Description

Connector and method for increasing its data transfer rate

The present invention relates to a structure of a connector and a method for speeding up the data transmission rate of the connector by adjusting the internal structure of the connector.

In modern electronic devices, USB is a serial port bus standard for connecting computer systems and external devices. It is also a technical specification for input/output interfaces. It is widely used in digital products such as personal computers and mobile devices, and is extended to photography. Equipment, digital TV, game consoles and other related fields. In order to smoothly transmit data and signals between the computer and external devices when the connector ports are connected, how to design a low-loss connector suitable for high-speed digital transmission is very important.

In response to the era of the Internet of Things, the amount of information and data is increasing day by day, and the high-speed data transmission function has become the goal pursued by the market. Therefore, high-speed USB transmission lines are introduced with the trend. The introduction of the USB Type-C interface connector not only reduces the size, weight and thickness of the connector itself, but also allows the plug end to be connected to its mating socket end on the front and back during the insertion action, and conforms to USB data transmission. IF transfer rate requirements.

Currently, the USB 3.2 Gen 2 Type-C connector on the market has a data transfer rate of 10Gbps, and most USB 3.2 Gen 2×2 connectors with a higher data transfer rate are still under development. In terms of technical specifications, the theoretical transfer rate of USB 3.2 Gen 2×2 is up to 20 Gbps, which is twice that of USB 3.2 Gen 2. Type-C transmission lines and connectors designed with two channels must be used, and both the host and the target end have The corresponding chip can achieve a data transfer rate of 20 Gbps.

The internal structure of the USB 3.2 Gen 2 Type-C interface connector is roughly symmetrical up and down. Figure 1 shows the structure of the upper half of the plug end of the conventional USB 3.2 Gen 2 Type-C interface connector. The structure of the upper half of the socket end of the conventional USB 3.2 Gen 2 Type-C interface connector is shown in FIG. 2A and FIG. 2B .

The internal structure of the plug end 100 in FIG. 1 includes a plurality of pins soldered on a circuit board 160 for high-speed data transmission with a computer or other devices. These pins include sets of data transmission pin pairs 110, 120, 130, power pins 140a, 140b and ground pins 150a, 150b. The plug end 100 is positioned to be plugged and unplugged and supports the connection of various devices. Its main function is to provide data transmission and power supply, which plays an important role in the data transmission process, and is the most widely used connector type for high-speed data transmission today.

2A shows a plurality of pairs of data transmission pins 210 , 220 , 230 , power pins 240 a , 240 b and ground pins 250 a , 250 b inside the socket end 200 , all of which are soldered to a circuit board 260 . The circuit board 260 is a circuit board in a destination device for data transmission. FIG. 2B shows an insulator 280 covering the pins of the socket end 200. The insulator 280 is used to fix the pins, so that the pins can be firmly fixed in the socket end of the connector and not scattered due to the plugging and unplugging of the device. Lose.

The structural characteristics of the USB 3.2 Gen 2 Type-C interface connector are symmetrical up and down and the volume is reduced, and the internal space of the connector is reduced accordingly, resulting in the spacing of the data transmission pins compared with other specifications of the USB interface connector. The spacing of the data transmission pins much smaller. During high-speed signal transmission, in addition to the signal to be transmitted in the transmission channel, the signal transmitted by the adjacent data transmission pin will be sensed, resulting in a certain degree of coupling interference. In addition, the shrinking of the internal space will change the circuit parameters of the data transmission pins, resulting in unexpected resonance modes, resulting in increased loss of signal transmission in the resonance frequency region, so that when the plug end of the connector is connected to the socket end The ideal high-speed transmission effect cannot be achieved.

However, connector designers often expect signal transmission to operate in environments with relatively regular electromagnetic field distributions. In the conventional USB 3.2 Gen 2 Type-C interface connector, the data transmission pins are assembled with plastic parts or insulators in order to meet the plugging force during connection; or the specific purpose of the connector itself, such as After vertical turning and then connecting, the data transmission pins have some irregular shapes, which will also change the circuit parameters of the data transmission pins, resulting in irregular distribution of the electromagnetic field, which is the main cause of unexpected resonance modes. Therefore, the current USB 3.2 Gen 2 Type-C interface connector structure with a data transfer rate of 10Gbps, when the operating frequency is between 9 GHz and 14 GHz, there will be an unexpected resonance phenomenon that is difficult to solve, causing transmission in this area. When the signal loss increases, the transfer rate of the connector is limited, making it difficult to further expand the application to the USB 3.2 Gen 2×2 interface connector with a data transfer rate of up to 20Gbps on the basis of the original hardware.

One of the objectives of the present invention is to provide a connector, which is slightly modified on the hardware basis of the existing USB 3.2 Gen 2 Type-C interface connector, so as to solve the problem of unexpected resonance in a specific area and provide wider signal transmission passband to achieve the data transfer rate of the USB 3.2 Gen 2×2 interface connector.
