Description
Technical Field
The present invention relates to a USB a male connector, and more particularly, to a USB a male connector capable of providing a better high frequency shielding effect and solving the problem of crosstalk expansion of a ground terminal.
Background
The USB connector has advantages of plug and play and high-speed transmission, and the transmission capacity of the USB connector has been greatly developed from the newly developed USB1.0 specification to the current microsbb 3.0 specification, and is currently and generally applied to electronic products. The USB related transmission protocol is a specification established by the USB association (USB Implementer form inc. USB-IF), and all USB connectors must conform to the specification to communicate with other USB connectors.
In the past, in order to suppress the problem of high-frequency noise, USB3.0 type a has been largely shielded by improving a ground terminal, for example: the grounding terminal is connected with the outer shell and is designed to be in a ring-shaped shielding type surrounding the periphery of the high-frequency terminal or the periphery of all the terminals, so that EMI and RFI generated by the high-frequency terminal are isolated by using a grounding signal; or the power terminal is arranged at the outer side of the high-frequency terminal to block the interference of the high-frequency signal and the outside by matching with the isolation effect of the grounding terminal.
However, the above mentioned high frequency noise suppression means of USB3.0 type A has the following problems and disadvantages to be improved:
first, the main influence object of high frequency noise is mainly the mutual interference between internal terminals, and only the ground signal isolation of the ground terminal is used, so its effect is very limited.
Second, the ground terminal is designed to be a ring-shaped shielding type, which effectively increases the overall shielding effect, but causes high-frequency crosstalk to be transmitted to other terminals along the ground terminal.
Third, the high-frequency characteristics are optimized by not fully utilizing the characteristics of the high-low potential difference of the power supply terminal.
Therefore, how to solve the above-mentioned problems and disadvantages is a direction in which the authors of the present invention and the related manufacturers engaged in the industry desire to research and improve.
Therefore, in view of the above-mentioned shortcomings, the present inventor has collected the relevant information, evaluated and considered in many ways, and tried and modified continuously with years of experience accumulated in the industry, and finally devised the present invention.

With the above description, it can be understood that the structure of the present invention can provide better high frequency shielding effect and solve the problem of crosstalk expansion of the ground terminal according to the corresponding matching of the structure, and the detailed description will be described below.
Referring to fig. 1 to 8, which are a perspective view of a preferred embodiment of the present invention and a cross-sectional view taken along line a-a of fig. 7, when the above components are combined, it is clear from the drawings that the transmission conductor set of the present invention is composed of a first high-frequency differential signal transmission conductor pair 1, a first power transmission conductor 2, a low-frequency signal transmission conductor pair 3, a second power transmission conductor 4, a second high-frequency differential signal transmission conductor pair 5, and a ground transmission conductor 6, and thus is a male connector conforming to USB3.0 type a specification, but the arrangement of the transmission conductors is different from the conventional one. In addition to using the first bending base portion 23 of the first power transmission conductor 2 to extend the terminal of the first power transmission conductor 2 from the front side of the first high-frequency differential signal transmission conductor pair 1 to the inner side thereof directly so as to isolate the noise of the first high-frequency differential signal transmission conductor pair 1 by using the potential difference (V +) of the first power transmission conductor 2, similarly, using the second bending base portion 43 of the second power transmission conductor 4 to extend the terminal of the second power transmission conductor 4 from the front side of the second high-frequency differential signal transmission conductor pair 5 to the inner side thereof directly so as to isolate the noise of the second high-frequency differential signal transmission conductor pair 5 by using the potential difference (V-, the second power transmission conductor 4 has the characteristics of GND at the same time) of the second power transmission conductor 4, as shown in FIGS. 2 and 3, thereby, the first and second power transmission conductors 2 and 2 are used, 4 is disposed between the first and second high frequency differential signal transmission conductor pairs 1, 5 to isolate the noise between them by potential difference, which is better than the isolation effect of the ground signal alone.
In addition, an annular isolation portion 63 is formed on one side of the ground transmission conductor 6, and is disposed around the first power plate contact portion 22, the low frequency signal plate contact pair 32, and one side of the second power plate contact portion 42, so as to isolate the interference entering from the front opening of the connector, and the elastic interference portion 631 touches the shielding shell 72, so as to guide the interference signal to the ground through the shielding shell 72. The length of the ground transmission conductor 6 is shortened so that the ground connection portion 62 is located between the low frequency signal plate-like contact pair 32 and the ground elastic contact portion 61 is located between the first high frequency differential signal elastic contact pair 12 and the second high frequency differential signal elastic contact pair 52 and on the same plane P (as shown in fig. 5), in other words, the entire length of the ground transmission conductor 6 does not extend between the first high frequency differential signal transmission conductor pair 1 and the second high frequency differential signal transmission conductor pair 5, thereby solving the conventional high frequency crosstalk problem transmitted between the first and second high frequency differential signal transmission conductor pairs 1 and 5 through the ground terminal. Therefore, the contact portions of the male connector terminals of the present invention still maintain nine (the first high-frequency differential signal elastic contact pair 12, the first power plate-like contact portion 22, the low-frequency signal plate-like contact pair 32, the ground elastic contact portion 61, the second power plate-like contact portion 42 and the second high-frequency differential signal elastic contact pair 52), but the welding portions do not include the ground transmission conductor 6, and only eight (the first high-frequency differential signal welding pair 11, the first power welding portion 21, the low-frequency signal welding pair 31, the second power welding portion 41 and the second high-frequency differential signal welding pair 51), and the ground elastic contact portion 61 can abut against the outer shell 92 of the female connector 9 through the ground terminal 91 of the female connector 9 when abutting against a female connector 9 (as shown in fig. 6 to 8).
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, therefore, the present invention should be construed as being covered by the appended claims and their equivalents.
