Description

Connector having a ground plate exposed at the front end of a tongue plate

Technical Field

The present invention relates to a connector, and more particularly to a connector with a grounding middle plate, which can expose the front end of a tongue plate.

In order to receive electronic signals and power from the outside, various electronic devices (e.g., smart phones, tablet computers, desktop computers, notebook computers, digital cameras, etc.) usually have to configure a signal Connector on the body of each electronic device, generally speaking, the signal Connector (Connector) refers to all the connecting components and accessories thereof applied to electronic signals and power, and is a bridge for all signals, the quality of which affects the reliability of current and signal transmission and is also closely related to the operation of the electronic device.

In view of the above, with the development of AR/VR applications and the emergence of 4K/8K displays, high-quality image transmission is becoming mainstream, so that the original analog interface is certainly unable to meet the needs, so that DisplayPort (display interface) becomes the preferred interface standard of Consumer Electronics (CE) devices, wherein, in response to the design requirements of modern people for the appearance of Consumer Electronics devices, most of them are "thin, short, and small", but the functional requirements are expected to have various novel functions, so that the practitioner must be weighed to fit the configuration space of each component in the Consumer Electronics device to meet the needs of the Consumer between appearance and function, so as to improve the competitiveness of the practitioner on the market, which causes the volume of DisplayPort to be also reduced, so as to move more available space, however, with the reduction of the volume of the DisplayPort, the two sets of signal terminals therein are necessarily closer, and for high frequency transmission, the two sets of signal terminals are likely to interfere, which adversely affects the high frequency and high speed transmission performance of the DisplayPort.

In addition, under the situation that the transmission speed of the digital signal has been advancing to high speed and high frequency, the digital signal transmitted through the signal connector itself will also generate loss during the transmission process, so that the loss is minimized, and the digital signal can obtain stable and accurate transmission quality, which has become an important issue in the development of the high frequency signal connector industry, especially, for the signal connector, the design of the mechanical structure and the analysis of the high frequency electromagnetic electrical design are two distinct professional fields, so how to obtain the best balance point in the engineering design is a difficult challenge.
