Description

Connector with grounding middle plate with front end of tongue exposed

This creation is about connectors, especially a connector whose front side of the grounding midplane can expose the front end of the tongue.

Press, all kinds of electronic devices (such as: smart phones, tablet computers, desktop computers, notebook computers, digital cameras... etc.) in order to receive electronic signals and power from the outside, usually must be in the electronic device The fuselage is equipped with a signal connector. Generally speaking, the signal connector refers to all connecting components and accessories used in electronic signals and power supplies. It is a bridge for all signals. Its quality affects the transmission of current and signals. Reliability has an impact, and it is also closely related to the operation of electronic devices. In addition, through the function of signal connectors, multiple electronic devices can be connected into a complete system, which can transmit electronic signals or power to each other. Therefore, the signal connector In fact, each electronic device is an indispensable element for realizing a predetermined function.

In conclusion, with the development of AR/VR applications and the emergence of 4K/8K displays, high-quality image transmission has gradually become the mainstream. Therefore, the original analog interface certainly cannot meet the needs, making DisplayPort (video connector) a The preferred interface standard for Consumer Electronics (CE) devices. Among them, in response to modern people’s design requirements for consumer electronic devices, most of them focus on "lightweight, thin and short", but they hope to have both functional requirements. Various novel functions. Therefore, the industry must compare the configuration space of each component in the consumer electronic device in order to meet the needs of consumers in terms of appearance and function, so as to improve its competitiveness in the market. In this case, the size of the DisplayPort needs to be reduced at the same time to free up more usable space. However, as the size of the DisplayPort shrinks, the two sets of signal terminals in it will inevitably be closer. For high-frequency transmission In other words, it is easy to cause interference between the two sets of signal terminals, which affects the high-frequency and high-speed transmission performance of DisplayPort.

In addition, as the transmission speed of digital signals has become higher and higher, the digital signals transmitted through the signal connector will also experience loss during the transmission process. Therefore, the aforementioned loss is minimized, thereby making Digital signals can obtain stable and accurate transmission quality, which has become an important issue in the development of high-frequency signal connector industry. Especially, for signal connectors, the design of the mechanical structure and the high-frequency electromagnetic In terms of sexual design analysis, they are two completely different professional fields, so how to achieve the best balance point in engineering design is an even more difficult challenge.

In order to stand out in the fiercely competitive market, the creators rely on years of professional experience in the design, processing and manufacturing of various power or signal connectors, and uphold the research spirit of excellence, after long-term hard research After experimenting, I finally developed a connector of this creation with a grounding middle plate exposed at the front end of the tongue plate. With the advent of this creation, we hope to provide users with a better experience.
