detailed description

The embodiments of the present invention are described in detail below, and the examples of the embodiments are illustrated in the drawings, wherein the same or similar reference numerals are used to refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are intended to be illustrative of the invention and are not to be construed as limiting.

The inventors of the present application have discovered and recognized that due to factors such as signal reflection, dielectric loss, and skin effect loss, the high frequency spectrum portion of the data signal after transmission through the data cable connector may be severely attenuated, especially when transmitted. When the rate reaches 10Gb/s, the data cable of several tens of centimeters will have significant attenuation, which will result in received waveform distortion and decoding errors. The longer the cable length, the more serious the distortion of the signal waveform will be. The signal distortion caused by the cable causes the bit error rate to rise, so that the actual data transmission rate does not meet the user's requirements.

The higher the data transfer rate, the more limited the cable length of the USB connector. For example, in the current USB 3.1 specification, the USB connector supporting the 10 Gb/s transfer rate is recommended to have a cable length of no more than 1 meter. In the related art, the length of the USB connector supporting the transmission rate of 10 Gb/s or more is not more than 1 meter. Even if the length of some products is more than 2 meters, the supported data transmission rate only reaches the standard of USB2.0 (480Mb/ s). However, there are many occasions in life that require a longer USB connector. Therefore, there is a need to increase the length of the USB connector while still meeting the requirements of ultra-high speed transmission rates.

Based on this, an embodiment of the present invention proposes a data cable connector.

The data cable connector according to the embodiment of the present invention will be described below with reference to the accompanying drawings. It should be noted that, in order to highlight the advantages, other leads other than the high-speed differential data transmission line in the data cable connector are omitted in FIGS. 1-5. There are many types of high-speed differential data transmission lines, such as shielded twisted pairs, coaxial pairs, and dual-core coaxial lines. The transmission lines shown in the drawings do not represent a specific type but are merely illustrative.

1 is a block schematic diagram of a data cable connector in accordance with an embodiment of the present invention. As shown in FIG. 1, the data cable connector includes a first connector 10, a second connector 20, and a connection cable assembly 30. In one embodiment of the invention, the data cable connector can be greater than one meter in length and the data cable connector can achieve a single channel data transmission rate of 10 Gb/s or more and meet signal integrity requirements.

The first end of the connection cable assembly 30 is connected to the first connector 10, and the second end of the connection cable assembly 30 is connected to the second connector 20. The connection cable assembly 30 has 2N data transmission units 31 and 2N data.
